MINING DISTRICTS.
BUTTE VALLEY MINING DISTRICT.
Including Sunnyside.
Gold is the only metalliferous product of importance in the Butte
Valley district. It has been produced from rich placer diggings in
gravels of both recent and ancient streams. Considerable gold is also
being recovered from quartz veins, and prospects for the future are
promising.
The settlement of Butte Valley (sometimes known as Butt Valley)
is situated at an elevation of 4600', ten miles by stage from Crescent
Mills on the Indian Valley Railway. It is about ten miles by trail west
of Greenville, and about nine miles by stage road south of Prattville.
Prattville is sixteen miles by stage northwest of Greenville, which is
ten miles northwest of Keddie, a station on the main line of the
Western Pacific Railroad. During the winter months heavy falls of
snow and rain make transportation difficult. The roads are good
during the summer.
Timber consists of pine, fir, spruce and tamarack. Water is
plentiful, since the North Fork Feather River, Indian Creek, Yellow
Creek, and several small streams flow through the district.
History of mining.
A few relatively small deposits of ancient auriferous gravel have
been mined in this district. Deposits of auriferous gravel occur in
the recent beds of the North Fork Feather River, Indian Creek and
Rush Creek. This gravel was once rich in gold, and was extensively
mined. At some localities it has been worked over a number of
times, and mining still continues. Very little mining of gold quartz
deposits has been done, although there are several prospects.
Topography.
Dyer Peak, elevation 7400', in the northeastern part, is the highest
point in the district. South of the peak there is a gradual slope to a
broad-topped ridge, elevation 6400', lying between North Fork
Feather River and Indian Creek. This ridge has a steep, north-
westerly face where bordered by the North Fork Feather River, and
is deeply cut by Indian Creek, which flows westerly. Red Hill rises
to an elevation of a little over 6000' between North Fork Feather
River and Indian Creek. The west side of Dyer Peak slopes pre-
cipitously to Big Meadows, which is a broad, flat area, lying at an
elevation of about 4300'. The streams in this area head in broad
shallow valleys, but as they approach North Fork Feather River they

( ut deep canons. This whole region drains into North Pork Feather
River, which heads in Big Meadows. Indian Creek drains all of the
southern portion of the district and Yellow and Chip creeks western
portions.

Geology.
In the northeastern portion of the district, on the slopes of Dyer
Peak, diabase and porphyrite are exposed. They lie in contact on the
north with basalt; on the west with the alluvium of Big Meadows,
and on the south wdth quartz-porphyry. The formations southeast
of here all strike northwest, being overlain by basalt to the northwest
in the regions of Prattville, Longville, Yellow Creek and Chip Creek.
The formations in succession from northeast to southwest are
peridotite, Arlington formation, diabase, Calaveras formation,
diabase, Cedar formation, peridotite and Calaveras formation. The
igneous rocks lie in narrow bands between the sedimentary for-
mations.
The Grizzly formation is composed chiefly of slates ; it is of Silurian
age and is the oldest fossiliferous rock yet discovered in northern
California. A small area occurs along the south contact of the
quartz-porphyry with the peridotite. The Arlington formation, sup-
posed to be of Devonian age, is composed of gray sandstone, slate
and conglomerate. The Calaveras formation, belonging to the Car-
boniferous period, consists of comparatively small lenticular masses
of quartzite, slate and limestone, cut by occasional auriferous quartz
veins and areas of gabbro and other intrusive rocks. The Cedar
formation, of the Juratrias period, consists of metamorphosed slates
and limestone, in which auriferous quartz veins have been found.
The diorite of this district usually contains plagioclase, hornblende,
black mica and quartz, and belongs to the quartz-mica-diorite series.
The sedimentary rocks in contact with diorite are greatly altered.
Peridotite is an intrusive rock originally composed of olivine, and, in
many cases, pyroxene. When pyroxene becomes the predominant
mineral the rock is called pyroxenite. Since its intrusion the olivine
and some of the associated minerals have been altered to serpentine.
Diabase and porphyrite are the other intrusive rocks of the Juratrias
period; they have been subjected to great pressure, accompanied by
an alteration of their mineral constituents. Andesites, which are
characterized by the predominance of pyroxene, are called pyroxene
andesites; in like manner some of the rocks are called hornblende
andesites. Generally the andesites are older than the rhyolites,
PLUMAS COUNTY. 3
dacites and basalts. The rhyolites of this district are light-colored,
usually lithoidal, and occasionally composed of perlitic glass. Basalt
is the most common and widely distributed lava of the district,
having escaped from many volcanic vents towards the end of the
Neocene period; it flowed down the canons cut in the older rocks,
occasionally damming them up, and giving rise to fertile meadows.
The relation of land and sea in northern California and Oregon,
was essentially the same throughout the Silurian, Devonian, Car-
boniferous and Juratrias periods; frequent oscillations of the land
with reference to the sea level are recorded in the changes of sedi-
ments. These strata, originally deposited horizontal, have since been
faulted and metamorphosed; the fractures have been filled with
auriferous quartz veins. The deformation did not all occur at the
same time ; the first tilting took place before the oldest Triassic forma-
tion was deposited. The rocks were again folded during the
Juratrias, at the close of which period the great deformation occurred
which raised the whole of northern California above sea. In this
district there were active volcanoes during the Carboniferous and
Juratrias periods. Many of these older eruptions have been folded
and displaced along with the sedimentary rocks. Later volcanic
action occurred during Neocene time. To the younger flows of basalt
this district is indebted for the development of its agricultural and
grazing lands. Lava in many places dammed up the canons, in which
by gradual accumulation of gravel, sand, mud, infusorial earth and
vegetable matter, beautiful meadows formed, as typified by Big
Meadows, Humbug Valley and Butte Valley.
Mineral deposits.
By the disintegration of the auriferous slates of the Cedar and
Calaveras formations gold has been furnished for placer mines in the
Quaternary stream gravels of Indian Creek, Rush Creek, and the
North Fork Feather Biver. The deposits in the region of Lot's
diggings and Dutch Hill are typical occurrences of auriferous gravels
of ancient streams. They have all been mined and the latter is said
to have been rich. The gravel at Dutch Hill is about 1000' above the
North Fork Feather River and at Lot's diggings near the latitude of
the fortieth parallel, the gravel lies nearly 4000' above the level of
the river where it cuts across the range. It is evident that there has
been a great change in the drainage of the country since these gravels
were deposited.
Lode mines and prospects in this district are limited to the
auriferous slates, of which the Cedar formation and the Calaveras
formation have been the most productive. Intermingled with the
auriferous slates are eruptive rocks, and it has been found that the
4 MINES AND MINERAL RESOURCES.
most promising prospects of the district are located near the borders
of these eruptive masses. The ore bodies may be in the auriferous
slates or the eruptive rock, but in either case they are not far from
the contact.. Among the quartz mines and prospects are the Saver-
cool and Del Monte mines on both banks of the North Pork Feather
River just to the north of Seneca, the Lictum and Plumas Amal-
gamated quartz mines in the Calaveras formation between Seneca and
Indian Falls, and the Elizabeth Consolidated in the Cedar formation
to the east of Red Hill. Considerable quantities of gold have already
been taken out, and the future is promising.
CRESCENT MILLS MINING DISTRICT.
Including Greenville.
The leading mineral product of this district is gold, though some
silver and copper are produced as by-products. The gold has come
mainly from the Crescent Mills belt of quartz mines, but it has also
been mined in the recent and ancient stream gravels. Exposures of
iron ore occur in the district, but iron has not been exploited.
Crescent Mills is in the north central portion of Plumas County.
It is a station on the Indian Valley Railroad, ten miles from Paxton,
the junction. Greenville lies nearly four miles northwest of Crescent
MiUs.
Staging is difficult during the winter, as the heavy precipitation of
rain and snow renders the roads bad, but during the summer months
traveling is quite good.
The elevation of Crescent Mills is 3520', and that of Greenville
3580'. Both are situated on the west side of Indian Valley. During
the winter months cold, wet Weather is typical, but it is warm and dry
as a rule during the summer.
Considerable timber is found covering the slopes and ridges sur-
rounding Crescent Mills. Yellow and sugar pine with some fir, spruce
iind tamarack are common, and underbrush grows on the slopes.
AVolf Creek, draining the country north of Greenville, Dixie Creek
to the south, and Indian Creek, comprise the natural water supply.
In addition, a large reservoir, called Round Valley Reservoir, is
situated at an elevation of 4480', about two miles south of Greenville
and west of Crescent Mills.
History of mining.
The principal producing mines have been the Crescent Mills, Green
Mountain, Indian Valley and McGill-Standart, which lie in the
Crescent Mills mining belt. In October, 1914, there were but two
active producers.
PLUMAS COUNTY. 5
Placer mines in the auriferous gravels of present streams have been
worked for some years. Near Arlington Bridge and Shoofly Bridge,
both on Indian Creek southwest of Crescent Mills, mining is still
going on. The annual yield, including placers in Light's Cailon and
above Flournoy on Indian Creek, is about $10,000.
Some mining of auriferous gravels of ancient streams has been
done. One placer, one-third of a mile northwest of Round Valley
Reservoir, is said to have yielded $150,000.
The total production of the Crescent Mills belt is stated to have
exceeded $6,650,000.

Topography.
The district is situated on what is generally known as the Grizzly
Mountain block, which lies at the northern end of the Sierra Nevada,
northeast of the main crest, and between it and the Diamond Moun-
tain block.
The Grizzly block comprises the Grizzly Mountains and Keddie
Ridge. In the Grizzly Mountains the crest line and escarpment are
well marked, presenting a steep slope of over 3000' at the west end
of Genesee Valley. The crest line sinks and curves toward the north-
west; disappearing at Taylorsville into the Indian Valley, it rises

again in Keddie Ridge and curves back to its northwest course. The
broad gap in the crest occupied by Indian Valley is more than a mile
in width. Keddie Ridge, which carries the crest beyond Indian
Valley, extends for about fourteen miles both extremities, ending in
plains.
The southwest slope of Grizzly Mountains is gentle. About
Crescent Mills and Greenville, the block is broken down to the level
of Indian Valley, which crosses the main crest. This gives especial
prominence to the escarpment of Arlington Heights and Houghs Peak,
which form a second crest. Beyond Round Valley Reservoir the slope
is better preserved in the northwestern inclination of the divide
I etween Indian Creek and the North Fork Feather River.
Indian Creek, flowing in a general southwesterly direction from
Crescent Mills, has cut a deep notch through the Grizzly block, both
sides of which slope gradually to the crest.
The district is completely drained by Indian Creek and its tribu-
taries. Wolf Creek drains the northern portion, Dixie and Clear
creeks the southern, and Houghs Creek the eastern part.
Geology.
In the northern portion of the district, extending from Keddie Peak
westward, is a large exposure of Taylor meta-andesite. In contact
with this on its southern width is an extensive area of meta-rhyolite,
the latter completely enclosing the Greenville arm of Indian Valley.
South of this meta-rhyolite is an exposure of Arlington formation
having a northwest-southeast trend, and in contact on its northern
edge with the meta-rhyolite and the alluvium deposits of Indian
Valley. Bordering the Arlington formation on its southern edge,
Taylor meta-andesite which trends generally northwest-southeast, is
in turn bordered by a relatively large area of Shoofly formation.
West of Indian Creek there are four small exposures of basalt and
two of rhyolite. Two relatively small exposures of andesite are seen,
one about one mile east of Arlington Bridge; one capping some
auriferous gravels and in contact with the meta-rhyolite. Four small
areas of serpentine, one on the northern edge of Round Valley Reser-
voir, are enclosed by meta-rhyolite. The serpentine on the north of
Round Valley Reservoir is in contact with an exposure of grano-
diorite, which is fully enclosed by the meta-rhyolite. Another very
small exposure of granodiorite is seen fully enclosed by serpentine in
contact on all sides with the meta-rhyolite just to the northwest of
Round Valley Reservoir. A fairly large area of Taylorsville forma-
tion lies about two miles west of Greenville, and another lies two
miles southeast of the town, in contact with the alluvium deposits of
PliUMAS COUNTY. 7
Indian Valley. Dikes of rhyolite are seen in two places, one about
three-fourths of a mile diie north of Round Valley Reservoir in the
granodiorite, and three smaller ones in the Taylorsville formation
west of Greenville. A small exposure of auriferous gravels is seen in
the Shoofly formation, west of Indian Creek ; another partially capped
by andesite lies northeast of Greenville, and another is found about
three miles northeast of Greenville in the meta-rhyolite.
The meta-rhyolite is a massive gray siliceous rock generally con-
taining phenocrysts of quartz or feldspar in a uniformly fine, compact
ground mass. It is of pre-Silurian age, and the oldest rock in the
district. The next oldest is the Taylorsville formation of fine sedi-
ments, slates and thin-bedded sandstones of Devonian age. The
Taylor meta-andesite is decidedly green in color aind porphyritic when
unaltered. This great mass, comprising a lava flow, lies conformably
between the Arlington and the Shoofly beds. The igneous rocks of
the late Jurassic or early Cretaceous include serpentine, granodiorite
and rhyolite dikes. Most of the material included under the desig-
nation of serpentine is typical green serpentine. The rock called
granodiorite is a light-colored and for the most part medium-grained
rock, which looks like granite. The rhyolite dike rock varies from
light gray to pale green and reddish brown, containing small pheno-
crysts of quartz, but is rarely porphyritic. These are all later than
the formations with which they are in contact, and the latter are
later than the granodiorite. During the Tertiary period a flow of
rhyolite of Miocene age took place. This is a siliceous lava, generally
light-colored or brownish and more or less porphyritic, with grains of
quartz and sometimes with scattered crystals of feldspar or -biotite.
The andesite of the Pliocene period is a light gray lava more or less
porphyritic in thin section. A felty dark gray ground mass encloses
crystals of plagioclase, also hornblende, biotite and pyroxene in
various proportions. The exposure east of Arlington Bridge is black,
and breaks with irregular fracture. The andesite overljdng the
auriferous gravel, a mile northeast of Greenville, is richer in augite
and poorer in amorphous matter than that near Arlington Bridge.
The basalt, seen on the ridge west of Shoofly, in part covering rhyo-
lite, belongs to the Quaternary period. It is a lava wihich is darker
colored, more compact, and heavier than andesite and frequently
contains visible grains of yellowish-green olivine.
On the valley border, one mile northeast of Greenville, there is a
mass of gravel exposed along the road for over half a mile which may
represent an early diversion of the Jura River. These gravels belong
to the Quaternary period. The valley alluvium, also of the Quater-
nary, is the sediment which fills Indian Valley. It contains some
8 MINES AND MINERAL RESOURCES.
gravel, but sand ie more widely distributed and silt is the most
common material, making an excellent soil for agriculture.
Mineral deposits.
Two types of auriferous gravels have been mined in this district:
(1) the gravels of the present stream beds and the terraces near
them; and (2) the gravels of ancient streams or high gravels.
Under the head of present stream gravels are small workings on
one of the benches near Shoofly Bridge by water taken out of the
narrows and having a fall of nearly 100'. Placer mining has also
been carried on along the upper course of Wolf Creek.
A third of a mile northwest of Bound Valley Reservoir a placer
mine on the slope toward the reservoir is said to have yielded
i^l50,000. Its richness was attributed to residual material from the
veins of the Standart-McGill mine. This deposit comes under the
head of ancient stream gravels.
The principal production from the district has come from the
Crescent Mills belt, which extends from the neighborhood of Taylors-
ville N. 50° W. through the Crescent Mills and Greenville dis-
tricts to Wolf Creek, a distance of about fifteen miles, with a width
of a little over a mile. In the Crescent Mills district the metalliferous
deposits are confined chiefly to the igneous rocks in more or less well-
defined quartz veins running through the granodiorite. The veins
run generally parallel to the course of the belt, but in a few cases
there are small veins nearly at right angles to the others. The oi?e is
.auriferous pyrite, sometimes in small bodies, but generally dis-
seminated in the narrow strip of sheared rock of the partially formed
vein in which there is usually some quartz. The pyrite is nearly
always changed to limonite, setting the gold free. In the Green
Mountain mine, one mile west of Crescent Mills, one subordinate vein
carries a small amount of chalcopyrite, but in general copper is
absent.
EDMANTON MINING DISTRICT.
This district, including Meadow Valley, is typified by deposits of
gold and manganese. The gold occurs both in river and lake gravels
and also in vein deposits in a lode formation. The manganese is
found in both vein and lode formations.
The district is located in the west-central portion of Plumas
County, Edmanton is about thirteen miles by road west of Quincy.
The latter is connected by the Quincy Western Railroad to the
Western Pacific Railroad at Quincy Junction (Marston).
Road conditions, while fair in summer, are quite uncertain in the
winter months, due to rain and snow.
FLUliAS COUNTY. 9
The elevation of Bdmanton is 4900', and the climate combines
warm, dry summers with winters having considerable snow and
rainfall.
The district is included in the Plumas National Forest and contains
tamarack, fir, spruce, yellow and sugar pine.
The mineral of chief importance is gold, found in the Diadem lode,
and also in auriferous gravels. Two veins of oxide of manganese
are found near the Diadem lode, and also a well-defined vein of
hematite and magnetite.
Several lakes in the northern part of the district and the head-
waters of numerous small tributaries to the North and Middle Fork
of the Feather River assure a good water supply, while considerable
uncut forest furnishes plenty of fuel and timber.
History of mintng.
The auriferous gravels of the Neocene period have been mined at
the Monte Gristo claims, about two miles west of Edmanton, by
means of a tunnel. Similar deposits have been noticed on the top of
Spanish Peak, and also a mile and a half west of the peak. Two
miles east of Buck's Ranch, pebbles like those at the Monte Cristo
claim were noted, and about three miles southeast of Edmanton a
large deposit of similar character is seen.
The Pleistocene lake gravels in the vicinity of Grub Flat have been
mined over by hydraulicking.
The Diadem lode, composed of quartz veins in clay slate, containing
rich selenides of gold and silver combined with lead and copper, has
been exploited to a depth of over 300'.

Topography.
The general character of the country in this district is mountainous.
Edmanton is situated in Eagle Gulch, which traverses in a north-
easterly direction a rather continuous range of high peaks trending
northwest.
Buck's Ranch, approximately four miles southwest of Edmanton,
is located in this same canon, which has a gentle slope of about 300'
downwards from Edmanton to Buck's Ranch.
From Edmanton, to the northwest, there is a gradual rise for three
miles to the top of Spanish Peak, elevation 7047'. From Spanish
10 MINES AND MINERAL RESOURCES.
Peak northwest to Mt. Pleasant, for three miles, the top of the ridge
is nearly level, Mt. Pleasant being 7111' in elevation.
On the eastern slope of the ridge, between Spanish Peak and Mt.
Pleasant there is a chain of glacial lakes, connected by small tribu-
tary streams, flowing into Silver Creek, which, in turn, drains into
Spanish Creek, thence into Indian Creek and the North Pork Feather
River.
To the southeast of Edmanton there is a gradual rise to the top of
a broad-topped plateau trending southeast. The general surface of
this plateau is rather even, the few peaks being all of about 5500'
altitude. As the plateau nears the canon of the Middle Fork Feather
River, there is an even, but somewhat steep drop of about 2500' It
is drained on the southern side by Bear Creek and smaller tributaries,
which flow into the Middle Fork Feather River. On the northern
slopes it is drained by Rock Creek and tributaries, which flow into
Spanish Creek, Meadow Valley and Grub Flat, about three iniles
northeast of Edmanton, having an average altitude of 3900'. Big
Creek, flowing through Eagle Gulch, drains Meadow Valley and flows
into Rock Creek and thence into Spanish Creek.
Geology.
The southern portion of the broad plateau region to the southeast
of Edmanton, where cut through by the Middle Fork Feather River
and Bear Creek, consists of the Calaveras formation. This extends
northwesterly to Haskins Valley. North of the eastern portion of
this belt of Calaveras fornaation is a broad capping of andesite of the
Neocene period. This covers the broad plateau section to the south-
east of Edmanton and extends north as far as Meadow Valley. West
of the andesite capping and north of the, Calaveras formation is a
strip of granite formation of the bedrock series nearly two miles in
width and extending westward about three miles, where it broadens
out to the north, covering Spanish Peak ridge as far north as Mt.
Pleasant and all the country to the west excepting Buck's Valley,
Haskins Valley and a strip about two miles long by one-half of a mile
wide on the top of Spanish Ridge, which is covered by an andesite
capping.
On the north and east slope of Spanish Peak ridge is a series of fine
moraines which form an area more than four miles long, as far south
as Spanish Peak.
East of this morainal deposit is a narrow strip of Calaveras forma-
tion. This strip of Calaveras formation is in contact on the west with
the granite from Spanish Peak southerly.
PLUMAS COUNTY. 11
To the east of the last mentioned Calaveras formation is a strip of
amphibolite schist, trending generally in a southeasterly direction.
East of this comes a strip of Calaveras formation, and then serpentine.
Meadow Valley and Grub Flat are composed of gravel beds of the
Pleistocene period.
The bedrock series embraces sedimentary rocks which were turned
into a nearly vertical position during or before the post-Juratrias
deformation, together with associated igneous rocks. The rocks of
the Calaveras formation are metamorphosed sedimentary rocks of
Carboniferous age. The amphibolites and amphibolite schists are
metamorphosed igneous rocks. Serpentine comes under the head of
the magnesian series, since magnesia is a prominent constituent. The
granitoid rocks include the granites, granodiorites and quartz-
diorites.
The superjacent series consists of late Cretaceous, Eocene, Neocene
and Pleistocene sediments lying unconformably on the bedrock series.
During the Neocene period this district was a country of low relief,
and the auriferous gravels were deposited by streams during this
period.
Under the head of the superjacent volcanic rocks may be classed the
basalts and andesites. These are of the Neocene and later periods.
There is a general fault zone trending to the southeast, running
nearly six miles along the east side of Spanish Peak. There is also
evidence of faulting along the Diadem lode at Edmanton; this is in
the same general fault zone as that along Dogwood and Bear creeks
and the east slope of Spanish Peak ridge. The displacements appear
to have taken place after the last andesitic eruptions, either at the end
of the Neocene or early in the Pleistocene.
Mineral deposits.
The gravel deposits of the district are mostly those of the Spanish
Peak gravel channel. They are made up of pebbles of pyroxene-
andesite, and were mined at the Monte Cristo claim at the south edge
of the deposit. Another exposure is seen on the top of Spanish Peak
itself, and again at a point one and one-half miles west of Spanish
Peak, the gravel being capped by andesite breccia. Another exposure
of gravel overlain by andesite breccia, is seen on the flat six miles
southeast of Spanish Peak. The pebbles here are mainly of quartzite
and other siliceous rocks.
The gravel beds of Grub Flat and vicinity are made up of Pleisto-
cene lake gravels. A large area of the lower gravel beds have been
hydraulicked. Underlying the well-rounded gravel northwest of
Grub Flat is some decomposed 'cement' gravel, made up of small
12 MINES AND MINERAL RESOURCES.
round, red, brown and white particles, between which decomposed
tuff has been deposited.
The Diadem lode at Edmanton, with a strike of N. 37° W. and
dipping 60° NE., has an average width of 60'. The vein matter
is a highly ferruginous mass of material consisting of quartz, oxide
of iron, chalcedony and manganese in clay slate. The lode has been
exploited to a depth of 300'. Rich selenides of gold and silver com-
bined with copper and lead are found.
There is a well-defined vein of hematite and magnetite paralleling
the Diadem lode 400' westerly, and conforming to it in dip and
strike. It may be traced for more than two miles and varies from
6" to 3' in thickness.
A vein of oxide of manganese occurs near the Diadem lode, and
another deposit three-fourths of a mile due south is known as the
Penrose lode. The latter has been traced northwesterly as far as
Eagle Gulch. The manganese is in the form of pyrolusite and
psilomelane.
About two miles west of Spanish Ranch post office and about three-
lourths of a mile southwest of Meadow Valley bodies of chromic iron
are found in place, and abundant pebbles of chromic iron are seen in
the Meadow Valley Pleistocene conglomerate.
GENESEE MINING DISTRICT.
The mineral products of this district are gold and copper. Some
placer mining for gold has been done in Tertiary gravels, but at
present it is confined to the Quaternary stream gravels. Drift mining
for gold and copper is carried on in the Genesee mining belt, extend-
ing N. 22° W. from Ward's Creek to Lights Canon.
Genesee is situated about fourteen miles, by stage, from Crescent
Mills, in approximately the central portion of Plumas County. Cres-
cent Mills is on the Indian Valley Railroad, ten miles from Paxton, a
main line station on the Western Pacific Railroad, and about twenty-
nine miles, by stage, southwest of Susanville, county seat of Lassen
County.
Travel by road during the winter months is difficult on account of
heavy rain and snow fall, but during the summer months the roads
are quite passable.
Genesee is situated at an elevation of 3690' on the southern end of
Genesee Valley. The climate in summer is warm and dry, in winter
cold and wet.
Timber is quite plentiful on the surrounding ridges. Spruce, fir,
yellow pine, sugar pine and tamarack are found. The slopes are
covered with brush, principally manzanita.
PLUMAS COUNTY. 13
In the Genesee mining belt the ore, in some cases, is auriferous
quartz and limonite, but in others it is chiefly bomite, chalcopyrite,
ehalcocite, or copper carbonates. Placer mining for gold has been
carried on to some extent in the auriferous gravels of both ancient
and recent streams.
Indian Creek, including its tributaries, assures a plentiful water
supply to the whole district. Hosselkus Creek rising in the north
and flowing southwesterly. Hungry Creek in the northeastern part,
and Squaw Creek, Red Clover Creek, Wards Creek and Little Grizzly
Creek, in the southern part, all of which flow into Indian Creek, cover
the entire district.
The forest growth furnishes sufficient mining timber and fuel.
History of mining.
During the great gold excitement in California prospectors found
their way into the mountains about Indian Valley as early as 1850.
Many locations followed the discovery of the ''Bullion Ledge," a
short distance northwest of Greenville, in 1851. Gold was the
primary object of search, but the discovery of rich copper ores in
1865 led to the erection of a small furnace, which maintained a
sporadic activity for four years. The Gruss mine along Wards Creek
on the border of Genesee Valley has been in operation for over twenty
years. This is in the Genesee mining belt, in which in 1904 there
were five active mines. The belt extends from Wards Creek, N. 22''
W. to Lights Canon. Conservative estimates placed the production
of the Genesee belt at $450,000 up to 1904.

Topography.
The district lies on the long and gentle southwest slope of the
Diamond Mountain block, which extends from Honey Lake south-
westward to the Grizzly Mountains. Its crest line lies close along its
northeastern side, from McKesick Peak to Diamond Mountain. The
slope to the southwest has the appearance of a plateau, the prominent
features of Diamond Mountain block being the escarpment, the
plateau slope and the valleys along its Western border.
Kettle Rock Mountain is the greatest elevation in the district, being
7850' high, or about 2000' above the general level, but it rises for the
most part by such gentle slopes that it is not out of harmony with
the peneplain. The upper portions of the streams are in broad
shallow valleys, but as they approach the middle portion of the block

they cut deeper and deeper until they flow in canons. The canons
of Indian and Squaw creeks above Flournoy are examples, and they
open into a broad alluvial valley below. The general trend of the
valley belt along the border of the Diamond Mountain block is
southeast-northwest from Genesee Valley to Mountain Meadows.
Genesee Valley has a breadth of from one-third to three-fourths of a
mile and a length of nearly six miles northeast and southwest directly
across the general trend of the valley belt. It is a flat alluvial plain
on both sides of Indian Creek, with an irregular border from jutting
spurs and lateral branches running up Red Clover, Wards, Hosselkus
and Little Grizzly creeks. Between North Arm and Genesee Valley,
there is a gap forming a broad depression in the ridge crest that joins
Mount Jura and Kettle Rock. This gap is a remnant of the old valley
of the Jura River. Southeast of Genesee Valley there is a gradual
rise to a broad-topped plateau, cut with rather deep notches by the
eaiions of Little Grizzly, Wards and Red Clover creeks.
All of the drainage of the district goes into Indian Creek ; Hosselkus
Creek on the northwest, Indian Creek on the northeast, Red Clover,
Wards and Little Grizzly creeks, on the south drain into Indian
Creek, which in turn drains into the North Fork Feather River.
Geology.
The eastern portion of the district, except in the southeast comer,
is composed of a large mass of granodiorite, which projects in on the
north side of Genesee Valley to a point about two miles northeast of
Genesee. A relatively large exposure of basalt is seen in the south-
east. Lying north of Genesee Valley is a blunt wedge shaped area
of Trail formation with a base about two miles in width along
Hornfels Point. From Genesee Valley the Trail formation extends
southeast to the basalt area above mentioned. Just to the south of
this area of Trail formation is a small area of granodiorite. South of
Genesee Valley, lying between Trail formation and basalt on its east
and Robinson formation on its west, is a strip averaging about one-
half mile wide of Kettle meta-andesite. North of Genesee Valley is a
broad area of Kettle meta-andesite averaging about four miles in
width and trending northwesterly. North of Genesee Valley and west
of the granodiorite spur which lies north of Genesee Valley, is an
exposure of Swearingen slate, in contact on its west with Robinson
formation and Hosselkus limestone. South of Genesee Valley is a
strip of Robinson formation, trending northwest and southeast,
averaging a little less than one-half mile in width. North of Genesee
Valley the Robinson formation is divided into two narrow belts by
volcanic rocks, and is cut off by volcanic rocks about a mile south of
PLUMAS COUNTY. 15
X.ucky S. road, but reappears and shortly ends on the north side of a
ravine leading down to Peters Creek. North of Genesee Valley,
separating the Robinson formation, is a flow of Reeve meta-andesite
trending northwest. This is a narrow belt with a considerable
expansion about one and one-half miles north of Genesee Valley. It
is cut off by Hull meta-andesite on the north. A second belt similar
to the first, borders the Robinson formation on the west, but its long,
slender, dike-like south end, penetrating the Taylor meta-andesite,
does not reach Genesee Valley. South of Genesee Valley a small area
of meta-andesite occurs east of Ward's Creek, in contact with Robin-
son formation. On both sides of Genesee Valley, trending northwest
to a point about a mile south of Lucky S. road, where it is cut oflf by
Hull meta-andesite, is a strip less than one-half mile in average width
of Taylor meta-andesite. South of Genesee Valley a dike of Hull
meta-andesite cuts the Peale formation into two narrow belts for a
distance of about a mile and a half. West of the Peale formation
and on both sides of Genesee Valley is an exposure of Hull meta-
iindesite. To the south of Genesee Valley it occupies a rather broad
area in contact on the west with meta-rhyolite. North of Genesee
Valley and lying to the east of the Hull meta-andesite is a deposit of
Foreman formation, narrow near Genesee Valley and broadening out
to a width of aboijt two miles to the north of Taylor diggings. It is
again interrupted by North Arm, whence it continues northwest to
Mountain Meadows. On the west it is in contact with the Hinchman
sandstone. Several small areas of andesite are seen in this district.
One, about a mile long and less than one-half mile wide in its widest
portion, lies on Homfels Point; another, at the head of Foreman's
Ravine, overlies a small area of auriferous gravels. South of South
Fork Foreman's Ravine is an exposure of rhyolite, and another larger
exposure occurs about a mile northeast of Taylor diggings. Several
deposits of Tertiary auriferous gravels are seen: at Taylor diggings,
a mile northeast of the summit of Mount Jura there is a relatively
large exposure, and on the Lucky S. road a flat-topped mass of gravel
caps the divide and main spur for over three miles. A small mass of
«?ravel is seen on the Lucky S. road about two and one-half miles east
of Hull diggings, and there are three flat-topped deposits at an eleva-
tion of from 5500' to 5800' capping the divide between Wards Creek
and Little Grizzly Creek, southwest of Genesee Valley. Another
mass is seen on the divide between Wards Creek and Red Clover
Creek.
The oldest rock in the district, the meta-rhyolite, is a massive gray
siliceous rock which generally contains phenocrysts of quartz or feld-
spar embedded in a uniformly fine, compact groundmass. It is of
pre-Silurian age. The Peale formation, belonging to the Calaveras
16 MINES AND MlNEltAL R£SOUftCES.
group of Carboniferous age, is a reddish to brown slaty shale, passing
into tuflfaeeous sandstone and fine conglomerate. The Taylor meta-
andesite, also of the Calaveras group, is a decidedly green rock and,
in this district, has a pronounced porphyritic structure with pheno-
crysts of plagioclase or augite. The meta-andesite dips southwest
beneath the Peale beds. The Kettle meta-andesite of the late Car-
boniferous is decidedly porphyritic, with many small phenocrysts of
feldspar, some of hornblende and rarely quartz embedded in a
reddish-brown or gray partially crystalline groundmass« The
eruption of the great mass of Kettle meta-andesite probably occurred
about the time the Robinson formation was deposited. The Reeve
meta-andesite is composed of white crystals of plagioclase plentifully
scattered in a compact dark groundmass. The relation of the Reeve
meta-andesite to the Kettle meta-andesite is not clear, though it
appears that the Kettle meta-andesite is the older. The Robinson
formation includes a succession of variably sediments ranging from
shale to conglomerate and composed chiefly of igneous material. The
tuflfaeeous conglomerate and sandstone are composed almost wholly
of volcanic material erupted in connection with the eflfusion of the
mass of meta-andesite. It dips to the southwest between the Taylor
meta-andesite, which was the source of its material. The Robinson
beds evidently lie uncomforably beneath all the later formations with
which they come in contact. The Hosselkus limestone is dark blue on
fresh fracture, weathers light gray and contains a few veins of white
calcite. It is evident that in the Taylorsville region there is a
decided interruption between the Hosselkus limestone and the
Robinson formation. It is possible that their contact is a plane of
displacement. The Swearinger formation is chiefly a dark slaty
shale, sometimes more or less calcareous and again decidedly siliceous.
The Swearinger slate and the Hosselkus limestone are everywhere
conformable, the general dip is to the southwest beneath the
Hosselkus limestone and shows that in the Taylorsville region the
Jurassic has been overturned. The Trail formation, of Jurassic age,
includes a mass of strata composed largely of slaty shales with some
interbedded sandstones and conglomerates. The general dip of the
formation is southwest, at an angle ranging from 35° to 80° and it
passes beneath the Swearinger slate and Hosselkus limestone. The
horizon of the Trail formation appears to be unconformably over the
Swearinger slate. The Foreman formation is a succession of shale,
sandstone and conglomerate in which the sediment is for the most
part derived from rocks which are not clearly volcanic. The general
strike of the Foreman formation is northwest, and the dip is to the
southwest immediately beneath the Hinchman formation and all the
other formations of Mount Jura which have been overturned. The
PLUMAS COUNTY. 17
Hull meta-andesite of the late Jurassic is greenish to reddish in color.
The prevailing type is essentially non-porphyritic and, in general,
is only partially crystalline. The fact that it penetrates the Foreman
beds to the northeast of Mount Jura, indicates that its eruption took
place near the close of the Jurassic. The rock included under the
head of granodiorite is a light-colored, and for the most part, medium-
grained rock which looks like granite, composed chiefly of plagioclase
and feldspar. Where the granodiorite comes in contact with the
Swearinger slate and Trail formation, these have been converted into
dark, flinty hornfels. The andesite is a light gray lava more or less
I>orphyritic in thin section. It has a felty dark gray groundmass
enclosing crystals of plagioclase and hornblende, biotite and pyroxene
in smaller proportion. It occurs in sheets covering the older rocks,
and is of Pliocene age. The basalt is a darker colored, more compact
and heavier lava than the andesite, not plainly porphyritic, but
frequently containing grains of yellowish green olivine. This basalt
is made up of two lava flows of Quaternary age. The later basalt is
dark gray, holocrystalline and rich in augite. The earlier is black
and compact and contains much amorphous matter. Mount Ingalls
was the vent for the flow in this district.
Mineral deposits.
The placer deposits of this district are of two kinds. Tertiary
auriferous gravels and Quaternary stream gravels. Among the
former are those of the Mount Jura divide, extending northeast from
Mount Jura toward Kettle Rock. There are four areas, and the
divide preserves a cross section of the ancient valley once occupied
by Jura River. The two larger masses have been mined at Taylor
and Hull diggings. These four areas were in all probability once
connected. The gravels of the Mount Jura divide contain no pebbles
of the Tertiary lavas. The pebbles of Tertiary rocks present are all
of types that belong to the pre-Tertiary bedrock series. South of
Genesee Valley, there are three flat-topped masses capping the divide
between Wards and Little Grizzly creeks. These were mined at the
old Peake diggings. In these gravels, pebbles of old rhyolite or
quartzite like those of Grizzly Mountains are most abundant, with
some of darker igneous rock and a few of granite. Pebbles 6'' to 10"
in diameter are common, but boulders as large as 2' are rare.
Mining has been carried on in the present stream gravels of Indian
Creek above Flournoy, and on Little Grizzly Creek, one of the
strongest streams of the region. The entire annual yield of the
placer mines within and bordering on the Indian Valley quadrangle,
is probably somewhat less than $10,000.
18 MINES AND MINERAL RESOURCES.
Under the head of lode-mining, the mines of the Genesee belt are
important. The most continuous activity in the district has been
along Wards Creek on the border of Genesee Valley, where the Gruss
mine has been in operation for over twenty years. This mine is on
both sides of the contact between the Kettle meta-andesite and the
slaty shale of the Robinson formation. In the shale the partially
formed veins follow narrow sheer zones, in which there is some
auriferous quartz associated with limonite. The adjacent meta-
andesite is often decidedly slaty and its ores chiefly chalcopyrite or
bomite, with copper carbonates near the surface. Near by is the
Mve Bears mine, in the Robinson slate, and this is much like the
Gruss. The Green Ledge, Pilot, and others in the Kettle meta-
andesite have small veins of quartz with bornite and some chalcoeite.
The veins are generally less than 5'' in thickness. Across Genesee
Valley is the Cosmopolitan mine on the contact of the granodiorite
with the Hosselkus limestone and Swearinger slate. The ore is chal-
copyrite and bornite, forming solid bodies up to 15' in thickness. On
the surface the contact is marked by masses of garnet and epidote,
which were not seen beneath, but in the Duncan mine the garnet and
epidote are associated with the ore. The Bluebell mine is in the
Hosselkus limestone near the contact, and from one of its shafts some
tons of carbonate of copper have been brought up in connection with
cave breccia.
In the Taylor gravel diggings some years ago a bed of coal about
five feet thick, lying nearly flat beneath the auriferous gravels, and
resting directly on the upturned edges of Jurassic sandstone, was laid
bare. About one ton was mined for blacksmithing purposes.
GRANITE BASIN MINING DISTRICT.
Including Buckeye, Gold Lake and Merrimac.
The gold in this district is found principally in quartz veins in
granite formations. Some gold has been taken from auriferous
gravels of the Neocene period, both by hydraulicking and drift
mining, and some from the gravel of the Little North Fork River.
The district is situated in the western portion of Plumas County
and the eastern portion of Butte County. Buckeye, approximately
the center of the district, is on the boundary line between Plumas and
Butte counties. Buckeye is about six miles by trail due east of Big
Bar, a station on the Western Pacific Railroad, and about thirteen
miles by stage, northeast of Berry Creek, another station on the
Western Pacific Railroad.
Considerable snow and a rather heavy rainfall in the winter months
render the roads somewhat uncertain, but in the summer they are
quite passable.
PLUMAS COUNTY. 19
Buckeye is 5000' in elevation. Granite Basin is in the neighbor-
hood of 4500', and Gold Lake and Merrimac 4250' and 3900', respec-
tively. In the summer the climate is warm and dry, but the winters
are quite rigorous.
Mine timber and fuel are obtained from the surrounding forest,
which includes tamarack, yellow and sugar pine, fir and spruce.
The only mineral of importance is gold, which is mined both from
gold-bearing quartz veins and by hydraulicking. At the Horseshoe
mine, three miles southeast of Merrimac, the gravel of the Little
North Fork River is washed.
French Creek, Little North Fork, and their tributaries on the south
and west of the district and tributaries of the North Fork Feather
River on the north furnish a plentiful water supply to the district.
History of mining.
The Reynolds mine, three miles northwest of Merrimac, was worked
for some time, a quartz vein in granitoid quartz-diorite containing
the gold values; and narrow quartz veins in the granite area known
as Granite Basin have been worked. Some hydraulicking has been
done to the east of Buckeye and one drift mine has been worked at
Buckeye in the auriferous gravels.

Topography.
Granite Basin in the eastern portion of the district is a small granite
area formed by erosion, and lying mostly between 4500' and 5000'
altitude. Sloping gradually up to the north, there is formed a chain
of hills, chief among which is Frenchman Hill, about three miles
northeast of Granite Basin with an elevation of 5993', and Soapstone
Hill, about three miles northwest of Granite Basin, with an elevation
of 5500'. The general trend of this chain of hills is northeast. To
the west there is an easy raise to an elevation of about 5000', cut by
the canon formed by Marble Creek, on the western part of which is
situated Buckeye with an elevation of 5000'. About five miles due
south of Granite Basin, two rather pronounced promontories are
formed at the joining of Marble Creek, a tributary, and the Little
North Fork River. East of the Little North Fork, which flows
due south from Granite Basin, there is a fairly even slope to a broad
low-sloping area in which is situated Gravel Range and China Gulch.
West of the Plumas-Butte county line, the general slope of the whole
district is to the southwest. The slope is even and slight to French
Creek, which flows nearly due south throughout the district. This
portion of the district is cut by numerous small tributary streams of
20 MINES AND MINERAL RESOURCES.
French Creek flowing in a general westerly and southwesterly
direction.
The western portion of the district is drained by French Creek and
its tributaries which flow into the North Fork Feather River. The
northern part is drained by Grizzly Creek and tributaries, which in
turn, flow into the North Fork Feather River. The Little North Fork
and Marble Creek drain the southern and eastern portions, these
flowing into the Middle Fork Feather River.
Geology.
Granite Basin is composed entirely of granite of the bedrock series.
The exposure of this granite is somewhat circular with an average
diameter of approximately two and one-half miles. It is surrounded
by a wide area of araphibolite of the same series. In contact with
the amphibolite to the northeast is a fairly large area of serpentine.
Soapstone Hill, in the amphibolite area, is capped with serpentine, on
the northeast of which is a small area of Calaveras formation. Bear
Ranch Hill is capped with serpentine with a lens-shaped exposure of
Calaveras formation about one-fourth of a mile by a mile and a half,
to the east of and in contact with it. About a mile and a half to the
east of Buckeye there is a small exposure of serpentine.
In contact with the whole amphibolite area, except for a small part
about a mile and a half to the north of Buckeye where there is an
exposure of older basalt, is an area of serpentine about one-half of a
mile in width, broadening out both to the east and the west to a con-
siderable extent. In the southeastern portion of the district the
serpentine is in contact with an area of Calaveras formation about
two by four miles. In contact with the Calaveras formation on the
west is a comparatively narrow exposure of amphibolite, trending
northerly. In contact with and on the west of the amphibolite is a
large exposure of granite comprising the balance of the district and
all of that section to the southwest of Buckeye, Merrimac and Gold
Lake.
The older basalt is a sock-shaped exposure on the instep of which
Buckeye is situated. There is another small exposure of this older
basalt about one mile southeast of Buckeye.
The rocks forming the bedrock series are the Calaveras formation,
the amphibolites and amphibolite-schists, the serpentines of the mag-
nesian series, and the granites, granodiorites and quartz-diorites.
Two relatively small exposures of the older basalt of the Neocene
period, and a few deposits of auriferous gravels comprise the super-
jacent series.
PLUMAS COUNTY. 21
Mineral deposits.
Of the three exposures of auriferous river gravels in the district,
the one at Buckeye has been mined by drift mining. The others, one
a mile southeast, and one a mile and a half east of Buckeye, have
both been hydraulicked. All are capped by older basalt.
The Horseshoe mine, three miles southeast of Merrimac, is a present
river gravel mine. A dam is built across the Little North Pork and
the water turned into a flume. The gravel is then sluiced into the
narrow gorge of the horseshoe, and allowed to accumulate during the
summer. It is carried off during the winter months floods.
In the granitoid-quartz diorite three miles northwest of Merrimac
some quartz veins have been found to contain considerable gold.
The Reynolds mine was worked for some time.
In Granite Basin there are gold-bearing quartz veins that have been
worked with profit. The veins have a general northeast-southwest
trend. They are seldom over 2' in width and stand either vertical or
at a high angle. The ore contains auriferous pyrite as well as galena
and zinc-blende, and is said to run $20 per ton. These veins have
been worked at the Coquette and Robinson mines.
Limestone lenses found in the Calaveras formation east of Merrimac
have not been exploited.
JOHNSVILLE MINING DISTRICT.
Including the region about Johns ville, Jamison, Mohawk and Long Valley.
In the large area included in this district gold is found in lodes and
in both Tertiary and recent placers. The vein gold comes from the
notable region about Plumas Eureka, in a belt continuous with the
quartz-porphyry belt to the south in the Sierra City district. Placer
gold is found farther north in the valleys drained by the Middle Fork
Feather River.
The district is located in the south central portion of Plumas
County. Johnsville is eight miles by road west of Blairsden on the
Western Pacific Railroad, with which point it is connected by daily
stage (except on Sunday) in good weather. The condition of the
roads is fair in summer, but not dependable in winter.
The elevation of Johnsville is 5200', and there is a heavy precipita-
tion of rain and snow during the winter months, but the summers are
warm and usually dry.
The region is not far from the border of the Tahoe National Forest,
in which the chief growths are yellow and sugar pine, tamarack, fir
and spruce.
Gold is the chief mineral product of economic importance at the
present time. Many limestone masses and some marble occur within
22 MINES AND MINERAL RESOURCES.
the district, and a little has been burned for lime. A deposit of
magnetite occurs in the southern extremity of the district.
The water supply is good. Mohawk is on the Middle Pork Feather
River, whose numerous small tributaries run throughout the district.
Glacial lakes occur west and south of Johnsville.
Sufficient timber is furnished by the still uncut forest in the
surrounding region.
History of mining.
The Pleistocene or recent river gravels in the Middle Fork. Feather
River Valley were mined a long time ago, and in nearly all places
were found to be rich in gold.
Considerable hydraulic mining has been done on gravel occurring
at the south end of a spur from the andesite-covered Grizzly Moun-
tains and at the Cascade mine. Tertiary gravels have been
hydraulicked.
A gravel deposit four and one-half miles northeast of Johnsville
was penetrated by Millers lower tunnel in the year 1890.

Topography.
The general character of the country is mountainous. Johnsville
and Plumas Eureka are situated near the base of the east slope of
Eureka Peak, which has an elevation of 7490'. From Eureka Peak
a ridge curves north for two miles and then northwest for four miles,
the top being nearly level. South of Eureka Peak this ridge is
broken by the canon of Jamison Creek, from which it rises again to
form Bunker Hill, 7400' in elevation. The ridge continues south,
curving into the Downieville district.
East of Bunker Hill a number of highly elevated glacial lakes are
connected by streams, which flow northeast into Jamison Creek, and
thence into the Middle Fork Feather Kiver.
For several miles east of Eureka Peak ridge the country flattens
out, but is divided by many shallow stream depressions continuous
with the canons higher up on the ridge. Separating this locality
from Long Valley on the north is Big Hill, five miles northwest of
eTohnsville, and 5700' in elevation. It is of very low slope from the
south, but steeper on the north toward Middle Feather Kiver and
Long Valley. Big Hill also forms the divide between Little Poplar
Valley on the west and Jamison Creek on the southeast.
PLUMAS COUNTY. ad
East and north of Long Valley a high mountain chain runs in a
northwest direction. The northern part of this chain is caUed the
(jrizzly Mountains, of which the highest peak is 7777' in elevation.
Several spurs radiate down to Long Valley.
In the south the mountains are less steep. Happy Valley extends
east of Long Valley, separating the Grizzly Mountains ridge into a
widspread system of spurs to the south. Mt. Jackson and Penman
■peak occur on this system, the elevations being respectively 6625'
and 7280'. Mohawk Valley lies to the southwest. This is a broad
level valley running northwest along the Middle Fork Feather River.
The elevation of the valley is about 4500' above sea level.
Gsology.
The western portion of the district consists of folded slates and
cfuartzites of Calaveras formation, generally of nearly vertical dip
toward the east, and northerly strike,
Kimning through Eureka Peak and Bunker Hill the contact
between the Calaveras formation and the quartz-porphyry belt is .
continuous with that in the Sierra City district to the south. Except
for one small patch, this quartz-porphyry belt does not appear again
north of Eureka Peak until the base of the Grizzly Mountains, just
north of Long Valley, is reached. From here Ihe belt continues
northwesterly, in contact with the Calaveras on each side.
West of Eureka Peak a body of intruded gabbro occurs in contact
with the quartz-porphyry. Another body further south is possibly
connected with the first under the intervening glacial detritus.
if ihe country south of Mount Elwell, ii
24 MINES AND MINERAL BESOUBGES.
Augite-porphyrite extends north of Eureka Peak, in a belt super-
ficially resembling the quartz-porphyry. This rock has a schistosity
with a northwest strike and a dip of from 70° to 75° SB. It is in
contact with the Calaveras formation on the west. Near Johnsville
the belt is covered by glacial detritus, but south of Johnsville around
Mt. Elwell and Long Lake it is five miles wide.
The quartz-porphyry and augite-porphyry were extended in
Juratrias time or earlier, but have been compressed somewhat with
the Calaveras formation. The augitcrporphyry appears to be younger
than the quartz-porphyry.
An area of Robinson formation, composed of tuflf, trachyte, and red
slate, occurs in the northern portion of the district, separated from
the Calaveras formation by augite-porphyrite. The beds strike
northeast and dip 60° E.
In contact with this on the south near the head of Grizzly Valley
is an intruded body of granite-diorite. Granite-diorite bodies also
occur at the head of Little Long Valley Creek, in Happy Valley, and
in various other places at the edge of the andesite cap covering the
large area north and south of Grizzly Valley, and it is probable that
the entire cap is underlain largely by granodiorite.
An irregular shaped body of mica-schist is exposed near the upper
end of Grizzly Valley, in contact with granodiorite and partially
covered by alluvium and andesite. This formation is possibly a part
of the Robinson, that has been thoroughly recrystallized to form
schists.
Andesite, and some rhyolite and basalt, cover the uplands north of
Mohawk Valley. These lavas are not extensive about Johnsville, but
cover the region four miles to the west, and the peaks west of
Eureka Peak.
A series of limestone masses occur on Eureka Peak and Bunker Hill
in the Calaveras formation, crossing Nelson Creek Canon, and a body
of crystalline limestone occurs in Little Long Valley Creek Canon.
The Calaveras formation is of Carboniferous age. The Robinson,
also Carboniferous, is deposited on top of the Calaveras. At the end
of the Paleozoic era these sediments were raised out of the sea, folded
and compressed.
No sediments of the Juratrias period appear in the district, but
during that time quartz-porphyry and augite-porphyrite were
extended. At the end of the period these were folded and com-
pressed with the previous sediments in the first great Sierra Nevada
uplift. Extensive granodiorite intrusions, and also the gabbro,
accompanied this movement.
PLUMAS COUNTY. 25
Tertiary auriferous gravels accumulated in the Neocene epoch and
toward its end separate flows of rhyolite, basalt and andesite took
place.
Another uplift, accompanied by faulting with the downthrow on
the eastern side, followed the volcanic activity. One line of faulting
probably runs through the Mohawk Valley.
In early Pleistocene time scattered flows of basalt occurred, the
lava following the river valleys eroded in the andesite. After this
came a period of glaciation, shown by glacial detritus and lakes. The
following period extends into the present time.
Mohawk Valley is the remains of a lake that filled the valley in
Neocene and Pleistocene times. The lake obtained its maximum
development after the andesite eruption, which appears to have
formed it.
The rocks occurring within the district are Calaveras slate,
quartzite, and limestone, Robinson tuflP and red slate, mica schist,
augite-porphyrite, quartz-porphyrite, gabbro, granodiorite, andesite,
basalt and rhyolite.
Mineral deposits.
The most important mineral is gold, which occurs in quartz veins
in the southern portion of the region about Eureka Peak, and in
gravels of both Tertiary and recent streams in the central and
northern portions.
On the steep eastern slope of the ridge four and one-half miles
northeast of Johnsville, a large deposit of auriferous Tertiary gravel
is exposed, surrounded by andesite breccia. Its altitude is about
6500'. A gravel deposit under the andesite was penetrated by Millers
lower tunnel in the year 1890. The gravel was subangular, con-
taining small fragments of blackened wood, and was evidently a gulch
gravel. The bottom of the channel is 400' vertically below the top
of the ridge.
A small deposit occurs at a point two and one-half miles northwest
of Johnsville, on a bedrock of augite-porphyrite; some hydraulic
mining has been done here.
In the extreme northern portion of the district, gravel deposits
occur on two spurs of the Grizzly Mountains, about two and one-half
miles southeast of Tower Rock. They are in a channel continuous
with one in Honey Lake quadrangle, farther north. Gravel in this
channel is again exposed at the Cascade gravel mine, on Little Grizzly
Creek Canon, thirteen miles north of Johnsville, and four and one-half
miles southeast of Tower Rock. Calaveras formation composes the
greater part of the bedrock, and rising ground to the south and west
is covered by andesite breccia. Sandy layers are interstratified with

the gravel. The deposit is 325' thick. Large granodiorite boulders,
presumably from the granodiorite region to the south, are found in
the gravel and indicate that the river flowed north.
At the base of a spur from Grizzly Mountains on the northern slope
of Little Long Valley there is another exposure of gravel, probably
the southern continuation under the andesite of the Cascade mine
channel. Prom the bedrock Calaveras formation and quartz-porphyry
the elevation is 5600' to 6000'. On the south end of the spur a large
area has been hydrsulicked.
Under the andesite and rhyolite of Lava Peak between Little Long
Valley and Long Valley creeks the gravel is again exposed. On the
spur south of Long Valley Creek there is a similar, but more extensive
deposit, the elevation of some of this gravel being only 5000'.
The deposit of well-rounded gravel at the north end of Mohawk
Valley, when in place, rests on Carboniferous slates. The low alti-
tude, about 4500', of the portion about the mouth of Cedar Creek is
probably due to landslides. On the south it is in immediate contact
with the Mohawk Lake beds. This and the gravel of the northern
part of the channel are composed of pebbles with coarse sand and
very little fine sediment, so it is probable that this channel has a
steeper grade than the one in the southwest of the Downieville
quadrangle.
The Plumas Eureka, one of the most notable lode mines in the
Downieville quadrangle, occurs within this district on the eastern
slope of Eureka Peak, one-half mile west of Johnsville. The vein
matter in this mine is composed of firm white quartz containing a
large percentage of pyrite, with galena and sphalerite. The gold

occurs both free in the quartz and in the pyrite, in about equal
amounts. This mine has been worked profitably for many years, but
is now almost completely exhausted. The Little Jamison quartz
mine is one and one-fourth miles south of the Plumas Eureka. The
country rock in this neighborhood is quartz-porphyry, gabbro and
augite-porphyry. Much of the surrounding region is covered by
glacial drift.
LA PORTE MINING DISTRICT.
Including the region about La Porte and American House.
This district has been the largest placer gold producer in Plumas
County. The main Tertiary river channel west of the Neocene divide
in the Downieville quadrangle runs through La Porte. As in the
adjoining district, however, no gold is obtained from recent gravels
or from quartz veins at present. La Porte is the principal shipping
point of the region. It is estimated that at least $60,000,000 was
forwarded from here from 1855 to 1871, including considerable gold
obtained before 1855 from the present rivers.
La Porte is located in the southwestern comer of Plumas County,
near the Sierra County line. It is fifty-one miles northeast of Oroville
on the Western Pacific Kailroad and the Southern Pacific Railroad in
Butte County. A daily stage (except Sunday) runs from Oroville,
omitting only the worst of the winter when the roads are not passable.
There is also a daily stage from Marysville, sixty-five miles by road
southwest of La Porte. Roads to the north connect La Porte with
Quincy and with Clio.
The winter months are characterized by heavy rains and snow, but
the summers are tolerably warm and dry. La Porte has an elevation
of 5000'.
The district lies a short distance from the northern border of the
Tahoe National Forest. Yellow pine, sugar pine, tamarack, fir and
spruce compose the larger growths, and the steeper slopes are densely
covered with manzanita and ceanothus brush.
Gold alone constitutes the mineral production of the district.
There is a good water supply. Slate Creek and its tributaries flow
through the southern part, and the headwaters of the South Fork
Feather River in the northern portion.
Electricity at a moderate price is available as a source of power.
History of mining.
In the La Porte district the greater part of the auriferous Tertiary
river gravels have already been mined away. Together with Spanish-
town, 10,400,000 cubic yards of gravel had been excavated up to the
28 MINES AND MINERAL RESOURCES.
year 1891 and 800,000 cubic yards remained at that time as ultimately
available.
The gravels of the entire region have been mined by hydraulicking
and by drifting operations. In 1901 a tunnel was completed two
miles northeast of La Porte, and the channel was mined successfully
for some distance upstream.
About three miles northeasterly from La Porte the Feather Pork
Gold Gravel Company has opened the channel by a long tunnel, the
elevation of which was determined from borings. The channel was
profitably drifted upon to a point where it widened out so that the
gold was not sufficiently concentrated.
In 1905, La Porte produced $18,000 of placer gold; and in 1905,
$6600 in Gibsonville. In 1909 La Porte and Gibsonville together
produced $32,000.

Topography.
The La Porte district is a sloping region of few hills, to the north-
west of Slate Creek.
La Porte is situated at an elevation of 5000' on a gently sloping
ravine of a tributary that runs southeast into Slate Creek. The
latter, a branch of the North Fork Yuba River, flows southwestward.
Slate Creek Canon on the La Porte side is not steep, and is only about
800' deep.
North of La Porte the ground slopes gradually upward, until an
elevation of 5500' is reached; then the grade increases to the top of
Bald Mountain, 5918' in altitude and one mile north of La Porte.
The southern slope of Bald Mountain forms a watershed for the creek
running through La Porte, but on the northern slope tributaries of the
South Fork Feather River flow north to meet the South Fork in Little
Grass Valley. This broad level valley, running in a southwesterly
direction, lies between the ridge west of Gibsonville and Whiskey
Diggings on the southeast and Grass Valley Hill ridge on the north-
west. The depth of the valley is about 800', and the distance between
the ridges is two and one-half miles.
Lexington Hill, in the Bidwell Bar quadrangle west of Bald Moun-
tain, is a little over 5800' in elevation. The two hills form a con-
necting link from Pilot Peak between the Gibsonville ridge and a
similar continuous ridge in the Bidwell Bar quadrangle, on which
American House is located. This ridge is parallel to the Mooreville
ridge, but separated from it by Lost Creek Canon.
PLUMAS COUNTY, 29
Geology.
The greater part of the district within the Downieville quadrangle,
excepting the southern area, is covered by andesite breccia or Pleisto-
cene alluvium deposits. The broad Bald Mountain and Grass Valley
Hill ridges are covered by andesite, while alluvium occupies the
bottom of Little Grass Valley.
A belt of Calaveras slates and quartzites one mile wide runs north-
westward, through the district. On each side it is in contact with
amphibolite, the western contact passing a little east of La Porte.
The Calaveras formation is again exposed in Little Grass Valley north
of the lava cap.
The amphibolite continues westward into the Bidwell Bar quad-
rangle. Lexington Hill is formed of amphibolite. West of this area
of sediments, the amphibolite body continues until it comes in contact
with the serpentine and with the great body of granite which is so
prominent in the Bidwell Bar quadrangle. A long belt of the Cala-
veras formation, narrowing to less than one-fourth of a mile in the
north, runs in a north-south direction one mile west of Lexington Hill.
The amphibolite appears to have been originally augite tuflfs and
surface lavas, but these have been altered, so that it now consists
chiefly of green aluminous amphibole usually of the fine fibrous uralite
type, but in part of a more coarsely fibrous, recrystallized variety.
The amphibolite and Calaveras formation extend downward indefi-
nitely, and are continuous with the same formations in the Port
Wine district in the south.
The Calaveras is the oldest formation in the district. During the
Carboniferous period it was deposited as shale and sandstone. At the
end of the Paleozoic era an uplift occurred which folded the strata
somewhat, and at the end of the Juratrias the first great uplift of the
Sierra Nevadas closely folded and compressed the sediments, and thus
metamorphosed them into slates and quartzites.
During the Tertiary period erosion was at first rapid, but in the
latter part, in the Neocene epoch, the country had been worn low, and
the velocity of the various streams reduced so that auriferous gravels
accumulated. These and the surrounding region were then covered
by a mud flow of andesite breccia. The andesite flow in places covers
some older massive basalt which preceded the andesite, and the basalt
occasionally covers the auriferous gravels, but the basalt flow was not
extensive.
At the end of the Neocene epoch the region was again elevated, the
movement being accompanied by faulting and an increase in the rate
of erosion.
Glacial detritus, which characterizes the Pleistocene period, is not
found in the La Porte district.

The rocks which occur are: amphibolite, Calaveras slates, and
quartzite, andesite and older basalt.
Mineral deposits.
Placer gold in Tertiary river gravels is the only mineral product of
the district. No gold is produced from the gravel of modern rivers
or from quartz veins at the present time.
The main river channel west of the old Neocene divide (Sierra
Buttes) in the Downieville quadrangle runs through the district.
The channel slopes southward from Hepsidam and Gibsonville,
through La Porte and Secret diggings, then on to Scales, Indian Hill
and Camptonville.
At La Porte the well-exposed white quartz gravel lies on a bedrock
of amphibolite and the Calaveras formation. It may have come from
quartz veins immediately adjacent and now exposed in the old river
bed where the gravel has been hydraulicked away. The lower
gravels were quite rich, averaging from $2 to $20 per cubic yard. A
bank of gravel 250' by 100' and' 30' high yielded gold at the rate of
$20.87 per cubic yard.
Auriferous gravel occurs at Secret diggings on the main channel,
one mile south of La Porte, and at Bamards, one mile farther south-
west. The bedrock is in each case amphibolite and there is no
andesite in the vicinity. Both deposits have been hydraulicked.
Dutch diggings are at the northwest end of the La Porte gravel
deposit. Here the exposed channel is 500' wide, with steeply rising
rims. On the southwest side the amphibolite rim rises several hun-
dred feet probably without being influenced by faulting. Along the
road northeast and southeast of Bald Mountain the amphibolite is
exposed, showing that the northeast rim also rises sharply, in spite of
the downthrow fault which occurs between here and Dutch diggings.
The gravel banks show 80' of almost clean quartz gravel ; even next
to the bedrock few boulders occur over 6" in diameter. Fifty feet of
sands and clays occur above the gravel, the clay being partly car-
bonaceous, evenly stratified and conformable on the gravel. Above
the clays is a heavy cap of andesite tuff. Most of the gold was on
bedrock or within 2' of it; that in the upper gravels was fine
and flaky.
Two miles north of La Porte the Halsey bore hole showed the
following strata. Starting with the lowest first : 5' quartz gravel, 10'
gravel and clay, 2' gravel, 14' gravel and clay, 98' quartz gravel, and
316' of volcanic sand, clay and lava.
Near the Clay Bank tunnel, half a mile southeast of La Porte, there
was only 14' of gravel, covered by 167' of clay. Above the clay in
places a heavy body of gravel lies with many pebbles of andesite and

l>asalt, representing an intervoleanie channel later than the Tertiary
p:ravel channels.
A small patch of Tertiary gravel occurs at American House, in the
Bidwell Bar quadrangle. This deposit, lying in a sag 800' above
Salt Creek, probably represents a tributary of the main La Porte
channel. A capping of basalt covers the Calaveras bedrock east of
the gravel patch. The bedrock to the west is amphibolite.
On both east and west the bedrock rises several hundred feet,
showing the old river valley. A considerable body of white quartz
gravel underlies the alluvium deposit in Little Grass Valley, two miles
northwest of Bald Mountain. This has been much exploited by
shallow shafts, but, being lower than the South Fork Feather River,
because of excess water it can not be profitably mined. The gravel
is not thoroughly rounded, thus resembling that at La Porte and
Richmond Hill.
Above La Porte, the channel has been seriously disturbed by move-
ments in a fault zone which is at least one mile wide and which has a
general northwest direction. The total downthrow on the northeast
side is probably 520'. The first fault is exposed in the bedrock at the
upper end of the La Porte diggings ; here the downthrow on the east
side is 55', and the gravel beds are bent over the nearly perpendicular
fault scarp.
Three*quarters of a mile southeast of La Porte on a bedrock of
Calaveras formation a detached body of gravel lies abnormally
depressed 200' below the level of the old channel. At this point the
channel paralleled the fault lines, and several slices have been differ-
entially dropped or elevated. The downthrow is 200' to the north-
east, but there are several intermediate benches. The Clay Bank
tunnel, portal elevation 4000', has been driven 3000' northwest to
open a supposed channel, but no gravel of value had been found up to
1901. It is probable that only a fragment of the northeast rim, cut
off by a fault, exists here.
At Dutch diggings, at the upper end of the La Porte gravels, the
channel was drifted on northwestward for 500', and was* then found
to be cut off by a body of lava. The relations suggest that a down-
throw on the northeast side of at least 130' had been encountered.
This is no doubt the continuation of the fault zone that caused the
depression in the vicinity of Spanish diggings.
LIGHT'S CAftON MINING DISTRICT.
The mineral products of this district are gold and copper. Gold is
obtained almost wholly by placering and hydraulicking the gravels
of both recent and ancient streams. Copper is produced from the
32 MIKES AND MINERAL BE80UBCES.
mines in the northwestern part of the Genesee mining belt. Some
noteworthy deposits of iron ore in the district have not, as yet, been
exploited.
Engels, about centrally located in Light's Canon district, is at the
terminus of the Indian Valley Railroad, twenty-two miles from
Paxton, on the Western Pacific Railroad. The district as a whole is
in the north central portion of Plumas County and Taylorsville is
approximately seven miles, by stage, from Crescent Mills, a station on
the Indian Valley Railroad. The climate in winter is cold and wet,
and heavy rains and considerable snowfall renders travel by road
very difficult. In summer it is warm and dry, and the roads are
quite good.
Timber is plentiful throughout the district. The principal varieties
are yellow and sugar pine, spruce, fir and tamarack. Manzanita and
ceanothus brush cover the slopes.
The district is drained by Light's Creek and its tributaries.
Sufficient water for mining is obtained in the lower parts of the
district, but due to their altitude it is almost impossible to obtain
enough water for even a few weeks of each year to work the gravels
which rest upon the summits.
History of mining.
As early as 1850, the country about Indian Valley was prospected
for gold. In 1851 the * Bullion Ledge' was discovered a short distance
northwest of Gibsonville, and many locations followed. Within ten
years Greenville was an active mining camp. Copper ores were
discovered in 1865, but their noteworthy development has taken place
only within the last four or five years. No great mines had pre-
viously been developed around Indian Valley, but many small ones
contributed to a total output up to 1914, of about $7,700,000. The
ores carry values in gold, silver and copper. Iron ore, coal, building
stone and mineral springs are present, but have not yet become
sources of revenue. About the head of Light's Creek, Mountain
Meadows and Moonlight, ancient gravels have been mined in a small
way for over twenty years, and the total yield has been approxi-
mately $500,000. Placering of recent stream gravels has been carried
on at a number of points, particularly in Cooks Canon and on Light's
Creek, where rather persistent efforts have been made. The entire
yield of the placer mines within and bordering on the Indian Valley
quadrangle is about $10,000 annually.

PLUMAS COUNTY. 33
Topography.
This district lies in the northwestern end of the Diamond Mountain
block on the gently sloping southwest side. The block gradually
narrows beyond Lone Rock, loses its relative elevation, and dies out
in a plain before reaching the head of Susan River. The upper
courses of the stream are in broad, shallow valleys, but as they
approach the middle portion of the block they cut deeper and deeper
until they flow in canons. Light's Canon and Cook's Canon, opening
into a broad alluvial valley below, are good examples. Running
northeast, on the southwest side of the district is North Arm, a branch
of Indian Valley, which extends up Light's and Cook's creeks for
nearly five miles. Mountain Meadows, triangular in shape and from
one-fourth to nearly one mile in width, lies to the northwest of the
district. Widening to the northwest, it merges into the plains
bordering the volcanoes about Lassen Peak. Along the eastern side,
its margin is rather indefinite on the gentle slope of the Diamond
Mountain block. . It has a general elevation of 4800', and is about
1300' above the general level of Indian Valley and North Arm, from
which it is separated by a low divide at the head of Cook's Canon.
The drainage of this region goes into two separate systems, the
Great Basin and the Sacramento River. The northwestern part of
the district is drained by Willards, Williams and Cheney creeks into
Susan River, and finally into Honey Lake, which has no outlet. The
eastern and southeastern parts of the district are drained by the head-
waters of Indian Creek and Lone Rock Creek, one of its tributaries.
The southwestern portion is drained by Light's and Cook's creeks,
thence into Indian Creek, which flows into North Fork Feather River.
Geology.
On the west of the district is an exposure of Foreman formation
averaging about a mile and a half in width, trending northwesterly
from North Arm to Mountain Meadows. The west side is in contact
with meta-rhyolite, Robinson formation and Kettle meta-andesite, in
the order of their occurrence. On the east it contacts with Kettle meta-
andesite. Reeve meta-andesite and auriferous gravels. At the head of
Cooks Canon there is an exposure of Reeve meta-andesite overlain by
auriferous gravels to the north. East of the Foreman formation is a
broad area of Kettle meta-andesite, trending in a general north-
westerly direction with an average width of about two miles. Two
small areas of Foreman formation, entirely isolated from the ma;in
mass, are seen in the area of Kettle meta-andesite, one on Light's
Creek and the other on Surprise Creek. Lying between the Kettle
meta-andesite and the granodiorite is a long narrow strip of River
meta-andesite running a little east of south from Moonlight to Light's
34 MINES AND MINEBAL RESOURCES.
Creek, where it bends, running into the Kettle meta-andesite. The
balance of the district is composed of granodiorite, except where over-
lain by andesite and auriferous gravels. Between Lucky S. mine and
Lone Bock Creek is a mass of andesite, capping the granodiorite and
the auriferous gravels. North of Moonlight there is a mass of
auriferous gravels overlying Kettle meta-andesite and granodiorite;
and between Diamond Mountain, Thompson Peak, Lone Rock Creek
y.nd Lights Creek is a large area of auriferous gravels overlying the
granodiorite. Two large areas of andesite on the north, two small
ones in the west and east central portions cap the gravels.
The oldest rock in the district, the Kettle meta-andesite of Car-
boniferous age, is decidedly porphyritic, with many small pheno-
crysts of feldspar and some of hornblende, and rarely a few round
grains of quartz. These are embedded in a reddish brown or gray,
partially crystalline groundmass, containing small grains of plagio-
clase and quartz. The Kettle meta-andesite is clearly of volcanic
origin. Its mass is made up of an extended series of lava flows and
products of volcanic explosions, the individual sheets of lava and
tuff being locally visible. The Reeve meta-andesite, an igneous
eruption of the late Carboniferous, is made up of white crystals of
plagioclase plentifully scattered in a compact dark groundmass,
giving the rock a porphyritic structure. No phenocrysts of augite
are present, and the dense groundmass appears largely amorphous
and full of feldspar microlites. The Reeve meta-andesite occurs as a
definite flow and tuff forming a long narrow belt running northwest.
The relation of the Reeve meta-andesite to the Kettle meta-andesite is
not clear, though it appears that the Kettle meta-andesite is the older.
The Foreman formation of Jurassic age, is a succession of shale, sand-
stone and conglomerate, in which the sediment is for the most part
derived from rocks which are not clearly volcanic. In this district
the Foreman beds come in direct contact with the meta-rhyolite and
Robinson formation without any intervening Jurassic and Triassic
.strata. The rock included under the head of granodiorite, of late
Jurassic or early Cretaceous, is a light-colored and for the most part
medium grained rock which looks like granite. It is generally a
quartz diorite, but locally the orthoclase may increase and the rock
passes into granodiorite. Most of the granodiorite is rich in quartz
and hornblende and is fine grained. The quartz diorite is clearly
younger than the Kettle meta-andesite and the meta-rhyolite which
it intersects.
The auriferous gravels of the district are patches of the main mass
of Tertiary gravels spread over an area about twenty miles in length
by nine miles in breadth. The Moonlight region, twelve miles north
PliUltAS OOUNTT. 35
of TayJorsville at the hoad of Surprise Creek, shows a total thickness
of gravels of over 1000^ The lower 400' is chiefly sand, and the
upper 600' is gravel or conglomerate. The latter is sometimes so
firmly cemented that when the rock is broken the fracture passes
through instead of around the pebbles. The deposit at the southeast
head of Mountain Meadows is a body of well-rounded gravel which
cavers the broad and low divide between Mountain Meadows and
Cooks Canon. It is underlain by sand, and the whole mass is not
over 20' in thickness. On the Sierra crest, near Diamond Mountain,
at an altitude of 7000', there is a deposit of jgravel about 300' in
thickness, resting on the granite. Southwest of Diamond Mountain,
in the flat country drained by the headwaters of Indian Creek, the
gravels are widely distributed in a heavy body. The andesite, of
Pliocene age, is a lava usually light gray, which is more or less
porphyritic in thin sections. Crystals of plagioclase are numerous,
those of biotite, hornblende and pyroxene in various proportions are
somewhat less abundant. The felty dark gray groundmass contains
many minute microlites of feldspar and black grains of magnetite in
a light brown glassy base. It occurs in sheets around the volcanic
vent from which the flows and ejected material issued. The masses
around Lone Rock and between Lone Rock and Indian Creek are of
hornblende andesite, closely related to that north of Kettle Rock.
The andesitic tuff and breccia which form Diamond Mountain are full
of black bordered hornblende. It is evident that the eruptions of
lava occurred within the gravel period, overflowing the earlier gravels
and furnishing the material for the later ones.
Mineral deposits.
The auriferous gravels which have been mined in the district are
of two kinds: (1) gravels of the present stream beds and terraces
near them, and (2) the gravels of ancient streams, or high gravels on
the mountain summits far above the streams of today. Placer mining
has been carried on in the auriferous gravel of present streams in
Cooks Canon and several other small streams, but the most effective
and persistent effort has been made on Light's Creek. Here work is
carried on for several months every year with giants and water under
100' of pressure, but the amount of debris moved is small.
The gravels of ancient streams are mined near the border of Moon-
light, at the southeastern head of Mountain Meadows, and in Cook's
Canon. Operations have been maintained for a month or more every
year for twenty years, but the work is confined to the lower edges of
the deposits. As the gravels rest upon summits, it is almost impos-
sible to obtain water in quantities sufficient for ordinary mining even
a few days or weeks each year. In the east branch of Light's Canon
36 MINES AND MINERAL BESOUBCES.
the gravels have been prospected, and good values are said to have
been found in bore holes which penetrate the andesite covering to a
depth of 200' to 300'.
Several mines in the southern portion of the Genesee mining belt
are located in this district. In some deposits the ore is auriferous
quartz and limonite ; in others the ore is chiefly bomite, chalcopyrite,
chalcocite and copper carbonates. Quartz is the most common
gangue mineral, but in one case barite appears and in another a
irreen mineral like actinolite. A small vein of barite in the altered
andesites at the old Indian Valley silver mine locally contains traces
of copper ore. Near the northwestern end of the Genesee belt in the
Superior mine, the gangue of the bornite is a green fibrous mineral,
like actinolite. A number of parallel vertical veins are well exposed
in the open cut and contain disseminated particles and nodules of
bornite. The larger ore bodies are free from gangue. The wall rock,
a fine-grained granodiorite, is the same on both sides, and the veins
are sharply defined.
A promising deposit of iron ore is located eleven miles north of
Taylorsville at the southern border of Moonlight, in a broad valley at
an elevation of 5600', where an area of about two acres occurs having
led soil strewn with black chunks of hematite with some magnetite.
Some of the fragments are 2' in diameter. No excavations have been
made, but the ore on the surface and the color of the soil indicate a
considerable body of iron ore beneath.
About one-third of a mile wtest of this locality a small opening
exposes a mass of hematite, in part breccia, over 4' thick. It strikes
nearly east approximately in line with the area noted above, and dips
about 45° S.
A few degrees west of south from the two-acre area there are a
number of small pits and fragments of iron ore in line to an old
opening made by Hulsman, which exposes a vein-like mass of mag-
netite and hematite. Some of the fragments have magnetic polarity,
others are not magnetic at all. The opening is only about 10' deep,
and the ore is said to run out at that depth. It is possible that there
are two lines of iron ore deposits, one nearly north and south, and
the other approximately at right angles. The two lines appear to
meet in the two-acre area.
QUINCY MINING DISTRICT.
Including the region about Quincy, Elizabethtown and Wilson Point.
Small amounts of gold have been produced from the alluvial
deposits in American Valley and from a number of gold-bearing
quartz veins located within this district.
PLUMAS COUNTY. 37
Quincy, the county seat of Plumas County, is situated in the central
part. By road it is sixty-one miles northeast from Oroville on the
"Western Pacific Kailroad and Southern Pacific Railroad. The Quincy
Western Railroad connects Quincy with Marston, now called Quincy
Junction, on the Western Pacific Railroad about four and one-half
miles northeast. Roads from Quincy run north to Crescent Mills,
Taylorsville and Greenville, south through Gibsonville and La Porte,
west through Spanish Ranch, and southeast to Cromberg and
Mohawk. These roads are serviceable to ordinary traffic during the
dry warm summer, but in the winter a heavy precipitation of rain and
snow makes them often impassable. In the vicinity of American
Valley, however, the snowfall is very light.
The mountainous part of the district is covered with timber, con-
sisting generally of yellow pine, sugar pine, spruce, fir and tamarack.
Manzanita brush covers many of the steeper slopes.
In American Valley the growing of alfalfa and dairy farming are
profitable occupations.
Water is plentiful. Spanish Creek runs along the eastern edge of
American Valley and Thompson and Spring Garden creeks are
branches to the mountains in the south. The Middle Fork Feather
River, with its many tributaries, runs through the southern part of
the district.
History of mining.
Some years ago a shaft was sunk in the middle of American Valley
to reach the gold in the gravel deposits there, but little if any gold
was taken out.
,piacer gold has been mined, however, along the Middle Pork
Feather River, principally at English Bar, and at another bank
further to the east, and hydraulic mining has been carried on in con-
nection with a deposit of late Tertiary gravel three-fourths of a mile
northwest of Spring Garden Ranch.
About half a mile west of Nelson Point a Tertiary gravel deposit
has been hydraulicked, and three miles northeast at the New Nelson
placer mine a channel has been followed under the volcanic capping
by a tunnel.

In general, the district consists of the broad, flat American Valley
lying between mountains to the north and south.
American Valley is nearly two miles across at the widest point.

northern edge.
Quincy is at an elevation of 3407'. To the south a stream caoon
divides a moderately sloping spur from Claremont Hill, three and
three-fourths miles south of Quincy. This star-shaped hill is charac-
terized by many spurs with moderate slopes along their axes, but
whose sides drop steeply down to the intervening streams. Clare-
mont Hill consists of several peaks, the highest of which has an
elevation of 7014'. A level-topped spur extends southeasterly for one

mile to Crescent Hill, 6600' in elevation. From this point the ground
slopes down steeply, forming part of the north side of Middle Fork
Feather River Caiion.
Prom Claremont Hill a broad, flat divide extends southwest. At
the southern cd^e of this area is the steep Middle Fork Feather River
Canon. Several tributaries, about one mile long, run down the canon
sides to the river 1800' below.
East of Claremont Hill a s-pur extends out that is joined at a little
distance by a ridge of peaks running south to Limestone Point, 5811'
in elevation, and 1800' above the river.
The more gradual eastern slope of Limestone Point ridge is drained
by "Willow Creek, a tributai-y of the Middle Fork Feather River.
Further north, in Thompson Valley, Thompson Creek flows north in
the opposite direction and joins Spring Garden Creek, the eastern
branch of Spanish Creek.
The streams forming Spanish Creek flow northeast through

level grade. Uniting two and one-half miles northeast of Quincy, in
Spanish Creek, the waters flow north into Honey Lake quadrangle
where they join Indian Creek, which empties into the North Fork
Feather River, and later into the Sacramento.
Northwest of American Valley, in the vicinity of Elizabethtown,
the ground slopes irregularly to peaks of less than 5000' elevation.
Geology.
The greater part of the Quincy district is composed of closely
folded slate and quartzite of Calaveras formation. In the south-
western portion a broad belt of serpentine continues up from the
Sawpit district, and this is joined on the east by a body of amphibo-
lite. The northwestern corner of the district is composed of a large
mass of augite porphyrite. Claremont Hill and Crescent Hill are
capped by basalt, and a large area of basalt occurs several miles east
of Claremont Hill, covering andesite breccia, which runs eastward
across the ridges.
Serpentine occurs as a belt three miles wide along the Middle Fork
Feather River, but it narrows somewhat in the north.
West of Claremont and Crescent Hills the contact is with amphibo-
lite schist. Further north the contact is with the Calaveras forma-
tion. The serpentine and amphibolite schist extend from the surface
downward indefinitely, as they represent intrusions of basic igneous
rocks which have been metamorphosed to their present forms. North
of Claremont Hill the amphibole schist lens, in contact on both sides
with the Calaveras formation, narrows to a point.
^ All the region from Claremont Hill to the northeast of Thompson
Valley, including the rock under the alluvial deposit in American
*' Valley, is composed of the Calaveras formation.
^^ A recent fault occurs in the Calaveras formation a little southwest
of Spring Garden Creek and parallel to it.
^^"^ About one and one-half miles northwest of Spring Garden Ranch a
body of quartz-porphyry is in contact with the Calaveras formation
■ and the augite-porphyrite. This is schistose in the same direction
and in the same degree as the augite-porphyrite.
American Valley and Thompson Valley are covered by recent
Pleistocene alluvial deposits. American Valley represents a basin
filled with gravel, sand and other sediments deposited by large creeks
emptying into it. The valley may have been a shallow lake bed.
'-' The Calaveras formation was deposited in Carboniferous time, and
'^ is the oldest formation in the district. These sediments were meta-
jnorphosed to partly micaceous slates and to quartzites by land move-
ments at the end of the Paleozoic era and again at the end of the

Juratrias, the latter movement being the first great uplift of the
Sierra Nevada. The rocks that later formed the serpentine and
pyroxenite were intruded at about this time. Before this, during the
Juratrias period, the rhyolitic lavas and the basic lavas and tuffs
which were later compressed respectively to quartz porphyry and
augite-porphyrite, were formed. The age of the gold-bearing quartz
veins is probably early Cretaceous. During the later Neocene epoch
of the Tertiary period of erosion, auriferous gravels accumulated in
the Neocene rivers. Toward the end of the Neocene extensive mud
flows of andesite breccia occurred following smaller flows of massive
basalt. This was followed by an uplift which increased the rate of
erosion. In early Pleistocene time scattered eruptions of massive
basalt took place. No remains of the Pleistocene glacial period are
found within the Quincy district.
The youngest formation is the alluvial deposit in American Valley,
which was formed in recent Pleistocene time.
The rocks found within the district are: Calaveras slates and
quartzites, serpentine, amphibolite schist, quartz-porphyry, augite-
porphyrite, andesite-breccia and basalt.
Mineral deposits.
Qold forms the most important mineral deposit, occurring in both
the Tertiary and present river gravels, in the Pleistocene gravels of
American Valley, and in quartz veins. The only other mineral
deposit is a lenticular mass of limestone at Limestone Point, two
miles west of Nelson Point.
The auriferous gravels occurring three-fourths of a mile northwest
of Spring Garden Ranch belong to the volcanic period. Deposits
from Pleistocene lake beds cover the ground about the gravels, but to
the east they are covered by andesite. The bedrock is Calaveras
formation.
On the north side of the Middle Fork Feather River half a mile
west of Nelson Point a gravel deposit now exposed was presumably
at one time covered by the andesite breccia overlying the adjacent
country to the north. The gravel rests on a bedrock of Calaveras
formation and is only about 200' above the present river, at an eleva-
tion of 4000'.
Four miles northwest of Nelson Point on the south slope of Clare-
mont Hill, at an elevation of 6400', there is a channel containing
gravel composed chiefly of quartz and other siliceous rocks, largely
subangular in character, thereby indicating a small watercourse. The
gravel, which was covered by andesite breccia, contained a good deal
of gold in spots.
PLUMAS COUNTY. 41
The New Nelson placer mine is located three miles northeast of
Nelson Point on the slope of the high ridge overlooking the Middle
Fork Feather River. The channel is opened by a tunnel having an
elevation of 4500', and has been followed under the volcanic cover
toward the northeast; this channel may connect with the gravels at
Spring Garden, three miles northeast, or with the channel found in
a nearby tunnel of the Western Pacific Railroad.
The gravels at Spring Garden are, however, at least 500' lower
than at the New Nelson mine, due to an intervening fault running
parallel to Spring Garden Creek.
Auriferous Pleistocene gravel occurs at English Bar along the
Middle Fork Feather River, a little over two miles east of Nelson
Point. The deposit extends for a mile along the river. One mile
east of English Bar there is a similar but less extensive gravel deposit.
About one mile north of Nelson Point, on the west side of Willow
Creek, there is a considerable deposit of early Pleistocene gravel.
The western border of this area is 400' higher than the eastern side
on Willow Creek.
In American Valley Pleistocene gravels are found between Quincy
and Meadow Valley, several hundred feet above the present canon
of Spanish Creek on the north side of the stream. American Valley
was a lake for a short time after the dislocation at the close of the
Neocene period. Gravels indicating an outlet are found two and one-
fourth miles northwest of Quincy, near Elizabethtown. The eleva-
tion of the slate bedrock at this point is 3800', and at Quincy it is
3407'. The gravels correspond to some small remnants of bench
gravel about 500' above the present bottom of lower Spanish Creek
and East Branch. This outlet was later abandoned by the stream.
In the gulch from Elizabethtown to American Valley auriferous
deposits of later channels are found draining towisird American
Valley.
These deposits, 50' to 100' below the present creek bottom, connect
with the gravels buried below the alluvium of American Valley. No
rich gravel was found in the latter.
Quartz veins are abundant in the slates along Willow Creek east of
Claremont Hill. Others occur near the serpentine belt contact, on
the south side of the Middle Fork Feather River Canon, only a few
hundred feet above the river, opposite Crescent Hill. The veins are
part of the system which runs along the serpentine belt, similar to
that about Onion Valley. They strike in a northwesterly direction.

SAWPIT FLAT MINING DISTRICT.
Including Sawpit, Onion Valley (Eclipse) and Last Chance.
In this extensive area gold is produced chiefly from gravely of the
old Tertiary rivers. Gold quartz veins are known, but few are
developed, and the district may be classed as one of the smaller
nroducers.
ft.
The district occupies a portion of the southern part of Plumas
County. Sawpit is sixty-six miles by road northeast of Oroville on
the Southern Pacific Railroad and Western Pacific Railroad, and
fifty miles, by road, west of Clio on the Western Pacific Railroad. It
is one and one-half miles northwest of Onion Valley, also known as
Eclipse. Roads connect with Gibsonville and La Porte to the south
and with Nelson Point (nine miles) and Quincy (twenty miles) to the
north. The roads are fair and serviceable to ordinary traffic during
the summer, but in winter they are often impassable, the winter
months being accompanied by heavy falls of rain and snow. The
summers are generally warm and dry. Elevation of Onion Valley
6300'.
The district lies about five miles north of the northern boundary of
the Tahoe National Forest, and the vegetation includes yellow pine,
sugar pine, spruce, fir and tamarack, with the steeper slopes covered
by manzanita brush.
Limestone deposits are known within the district, but none are
utilized.
Water is plentiful. South Fork Feather River and Onion Valley
Creek have their sources within the district, and Nelson Creek flows
northwest to the Middle Fork Feather River, whose many tributaries
run throughout the northern part.
History of mining.
At Richmond Hill one-half mile southwest of Sawpit, auriferous
Tertiary gravels are exposed, and have been mined by hydraulic
operations. The Union Hill gravel mine, two miles to the east, on
the slope of the intervening andesite ridge, has also been worked by
the hydraulic method, as well as a deposit two and one-half miles
northwest of Onion Valley, at the base of an andesite capping.

Topography.
The district as a whole is quite mountainous. A number of
irregular ridges extend in various directions, some with steeply
sloping sides, others, like the one extending down to Grass Valley
PLUMAS COUNTY. 43
Hill, and the one on which Sawpit is located being more gradual.
Sawpit, at an elevation of 6050', lies on an andesite-covered upland
area trending in a northwest direction. On the north and west,
where the area of low slope ends, the V-shaped Middle Fork Feather
River Canon slopes down 1500' in one mile. Many tributaries, one or
two miles in length, run down the slope at right angles to the river,
Avhich here flows from east to west.
Onion Valley Creek drains the south slope of Sawpit Flat, and runs
west and then north, joining with the Middle Feather River in the
Bidwell Bar quadrangle.
This creek drains the northern slope of the ridge extending north-
oast from Grass Valley Hill in the La Porte District.
One and one-half miles south of Sawpit across the headwaters of
Onion Valley Creek, the highest peak of the Grass Valley Hill ridge
rises to an elevation of 6842'. The ridge continues eastward for a
mile, to a saddle where the road crosses, and then the ground slopes
first slightly and then much more steeply to the top of Pilot Peak,
7505' in elevation, and a mile and a quarter southeast of Onion Valley.
From Pilot Peak ridges radiate irregularly in various directions.
The Gibsonville ridge runs southwest, the Grass Valley Hill ridge
west ; the Sawpit Flat northwest, the Plumas-Sierra county boundary
ridge southeast. North and east of Pilot Peak, several spurs extend
for a mile or so, and then drop rather steeply to Nelson Creek.
Poorman Creek, a branch of Nelson Creek, runs between two of these
spurs, both of which have steep southern slopes. About four miles
southeast of Pilot Peak, the steep Blue Nose Mountain ridge runs
north from the Sierra-Plumas boundary ridge and forms the divide
between the headwaters of Hopkins Creek and a branch of Nelson
Creek. On the east side of Nelson Creek a long ridge with many
Fpurs extends north from Eureka Peak in the south. To the north
of the mouth of Poorman Creek, the slope from the ridge top down
is quite moderate, being from 1 in 7 to 1 in 8.
The drainage of the district in general is to the west and north, to
the Middle Fork Feather River, which flows west and south, flnally
emptying into the Sacramento River. In the southwest part of the
district, the headwaters of the South Fork Feather River run south-
west between Gibsonville and Grass Valley Hill ridges.
Geology.
The greater part of the district is composed of closely folded slates
and quartzites of Calaveras formation and serpentine, both extending
downward from the surface indefinitely. A body of amphibolite
occurs in the region of Sawpit and to the south; this also has an
indefinite downward extension. Andesite covers Sawpit Flat and

Grass Valley Hill ridge. Small areas of glacial detritus occur at
Onion Valley and a mile and a half southwest of that town. At
Onion Valley it is partially covered by alluvium.
In the extreme west, north of the andesite breccia and basalt
rapping about Fowler Peak, the Calaveras formation extends nortii-
ward in contact with serpentine on the east. Several long lenses of
limestone occur, one along Last Chance Creek and another farther
south.

The serpentine is extensively developed in this district, the belt
varying in width from three to four miles. The serpentine on the
broad flat interstream area northwest of Sawpit is covered by
andesite. At the upper end of Bird Caiioii, about a half a mile north
of Sawpit, a belt of amphibolite is seen in contact west and east with
serpentine and covered by basalt and andesite in the north. This
belt widens from one niile in the north to three in the south. The
serpentine and amphibolite form part of the great serpentine belt
which extends southward through the Downieville and Colfas
<{uadrangles.
The eastern contact between the serpentine and Calaveras forma-
tion runs in a northwesterly direction through Onion Valley, and
extends north under the andesite breccia cap, appearing again one
and three-fourths miles north of Onion Valley. The Calaveras for-
mation composes the remainder of the district from this contact
eastward. About four and three-fourths miles northeast of Onion
Valley the strata strike northwesterly and have a vertical dip; two
PLUMAS COUNTY. 45
and one-half miles further east, however, the strike is northeasterly
and the dip 80° toward the southeast.
The Calaveras formation is the oldest in the district, being of the
Carboniferous period. At the end of the Paleozoic era and at the
end of the Juratrias period the sediments were folded and compressed
in uplift movements. The later movement was the first great uplift
of the Sierra Nevada range. Basic rocks, such as diabase and
pyroxenite, which were later metamorphosed to amphibolite and
serpentine, were intruded at this time. The age of the gold quartz
veins is early Cretaceous. During the later part of the Tertiary
period, known as the Neocene epoch, auriferous gravels accumulated,
and these were covered in a few places by flows of massive basalt and
everywhere by mud flows of andesite breccia. Blue Nose Mountain
ridge is covered by massive andesite, and there is evidence that lava
issued from this region.
The flows of volcanic material took place before the end of the
Neocene. At the close of the epoch a movement, accompanied by
some faulting, increased the grade of the western slope, and the rapid
erosion which followed left the andesite only on' the high interstream
areas. During Pleistocene time a period of glaciation occurred,' and
glacial detritus remains in Onion Valley and in several patches to
the south and southeast.
The rocks found within this district are: More or less micaceous
slates of the Calaveras formation, quartzites of the same formation,
serpentine, amphibolite, andesite and basalt.
Mineral deposits.
The only mineral of present economic importance is gold. The
entire production comes from placer mines in the old auriferous
Tertiary river gravels, but gold is known to occur in quartz veins in
the neighborhood of Onion Valley. Deposits of light gray limestone
containing from 10% to 19.5% MgO are found at Last Chance, four
and one-half miles northwest of Onion Valley.
The Richmond Hill hydraulic gravel mine is located three-fourths
of a mile southwest of Sawpit, on Onion Valley Creek, at an elevation
of 5500'. Bedrock is serpentine on the west and amphibolite on the
east. The white quartz gravel is well exposed and not covered by
undesite breccia. It is not thoroughly rounded, thus resembling the
gravel underlying Little Grass Valley and at La Porte. The channel
may possibly run from Little Grass Valley to the Richmond Hill below
the andesite capping on the intervening ridge.
From the Richmond Hill mine the deposit is exposed for about a
mile northeasterly and is then covered by andesite. A gravel deposit
occurs on the same channel at the Union Hill mine, three-fourths of a

mile farther east, on the east side of the ridge. This mine has also
been worked by hydraulic operations.
Less than one-half mile north of Sawpit white quartz gravel
occurring under the black basalt has been drifted upon. The gravel
at Sawpit is probably on the Richmond Hill-Union Hill channel.
North of Sawpit the ridge is covered by andesite breccia. On the
northern border of this capping, two and one-half miles northwest of
Onion Valley, a deposit of gravel rests on serpentine bedrock. Imme-
diately to the west is an area of Neocene basalt, extending further
down the slope than the gravel deposit.
Two masses of white quartz gravel also occur at the north and
west base of Blue Nose Mountain, at the edge of the breccia capping,
on bedrock of the Calaveras formation.
Both deposits are about 500' below the Bunker Hill tunnel,
a mile and a half northwest of Hepsidam, a drift mine in the Gibson-
ville District. At the Bunker Hill mine the last of the La Porte
channel was seen. It is possible that the two deposits at the base of
Blue Nose Mountain represent downthrow portions of the Hepsidam
deposit. Extensive faulting has occurred in this region, which was
formerly, one of enormous volcanic activity. Lavas have issued here,
much of which is massive andesite, in part dikes, occupying fissures
in the bedrock.
On the ridge north of Poorman Creek two and one-half miles north-
east of Pilot Peak, the Blue Lead gravel mine is located. The white
quartz gravel has a rubble of andesitic boulders on top, resembling
the massive andesite immediately to the west.
Gold-bearing quartz veins occur at Onion Valley near the contact
between the serpentine and Calaveras formation. Veins also occur
further east in fissures in the Calaveras. About three miles northwest
of the town two or three veins occur in the Calaveras formation or
near the contact. They ha"ve a northwesterly strike, and are part of
a vein system that seems to run parallel or along the contact between
the serpentine belt on the west and the Calaveras formation on
the east.
SPANISH RANCH MINING DISTRICT.
This district, which includes most of Meadow Valley, is typifie^d by
deposits of both Pleistocene lake gravels and those of Neocene rivers.
Some chromic iron is found in place and pebbles of chromic iron are
common in the lake and river gravels.
The district is in approximately the west central portion of Plumas
County, Spanish Ranch being seven miles by stage west of Quincy.
Quincy is connected to Quincy Junction on the Western Pacific Bail-
road by the Quincy Western Railway.
The altitude of Spanish Ranch is about 3650^, and the cliinate is
warm and dry during the summer months, with much snow and raifi-
&11 m the winter. As may be expected, the condition of the roads in
winter is not dependable, but in the summer they are quite good.
The district is part of the Plumas National Forest, and it cont^ons
fir, spruce, tamarack, yellow and sugar pine timber. The slopes arc
usuaHy thickly covered with underbrush.
The chief mineral is gold, found in Neocene river gravels and in
Pleistocene lake deposits. Two deposits of chromic iron are found
in place in the district, one about two miles to the west of Spanish
Hftn^ Post Office, and the other about three-fourths of a mile south-
west of Meadow Valley.
Spanish Creek in the northwestern part of the district, Wapanse
Creek in the northeastern part, Rock and Snake creeks in the
southern part and several small lakes furnish a plentiful water supply
throughout the year.
-History of mining.
The Meadow Valley Pleistocene lake gravels have been very exten-
sively mined by the hydraulic method at Gopher Hill, a mile and a
quarter east of Spanish Ranch. A large area of the lower gravel beds
at Grub Plat, a mile and a half southwest of Spanish Ranch, have
been mined, as well as some of the gravels three and a quarter miles
east of Meadow Valley post office, on a branch of Slate Creek. The
old mines known as Shores Hill and Badger Hill on the ridges east
end west of Whitlock Ravine have been mined by hydraulicking.
At the west edge of the lava area which caps Chaparral Hill is a
deposit of Neocene river gravel which has been hydraulicked. There
are several other patches of the same gravels, some of which have
been worked to the east of Spanish Creek. The Bean Hill hydraulic
mine is two miles northwest of Spanish Ranch. Two miles north of
^anii^ Ranch the Pine Leaf channel has been worked underneath a
capping of andesitic tuflE at the Pine Leaf and Knewil mines.

Topography.
To the east of Spanish Creek, which flows in a general southeasterly
direction until it reaches Spanish Ranch, where it changes to an
easterly direction, there is a ridge extending from Chaparral Hill,
elevation 5500', in a general easterly direction throughout the district.
48 MINES AiSTD MiNEtlAL BfeSOUROilS.
The general slope of the ridge is slightly towards the east. It slopes
gently to the south into Mieadow Valley, the elevation of which is less
than 4000'. Two small hills of 4200' are seen in Meadow Valley east
of Spanish Eanch. To the southeast of Meadow Valley the ground
slopes in a gentle rise to another ridge extending in a general south-
easterly direction.
The whole district is drained by Spanish Creek and tributaries to
it, whose waters flow into Indian Creek, which in turn, flows into the
North Fork Feather River. Wapanse Creek, with headwaters at
Smith Lake in the north of the district, flows southerly into Spanish
Creek, draining Snake Lake Valley. Snake Creek and Bock Creek
drain the southern portion of the district.
Geology.
Spanish Creek, from its headwaters down to Meadow Valley, cuts
through a large area of serpentine. Chaparral Hill in the northwest
part of this section is capped with a deposit of andesite tuff. Meadow
Valley, Snake Lake Valley and several small areas, one to the east
of Badger Hill diggings and three on the sides of Rock Creek Canon,
are composed of Pleistocene lake beds. On the northern slope of the
ridge north of Meadow Valley is an area of the Cedar formation,
composed of little altered clay slates. This is in contact on the west
with the serpentine forming the ridge, on the south with the andesitie
tuff capping this ridge and on the east with the Calaveras formation.
A small exposure of serpentine is seen in Meadow Valley just to the
east of Spanish Peak. The ridge south of Meadow Valley is capped
with andesitie tuff.
The Meadow Valley lake beds of Pleistocene age are composed
mostly of gravel. Some time late in the Pleistocene the rocky barrier
between Meadow Valley and American Valley was cut through by
Spanish Creek, thus draining the lake.
The Cedar formation is of the Juratrias period, being the only area
assigned to that period in this quadrangle.
Of the bedrock series, only the serpentine and the Calaveras for-
mation are present in this district.
The andesitie capping, exposed on the ridges, is of the Neocene
period and belongs to the superjacent series.
Mineral deposits.
Gold is found in auriferous gravels of two periods and of different
modes of deposition.
Several exposures of Pleistocene lake gravels are seen in and
around Spanish Ranch. At Gopher Hill, a mile and a quarter east
of Spanish Ranch, the gravels have been mined extensively by the
hydraulic method. On the exposed cliffs there are two layers -of
gravels, about 50' apart, of a light buff color, and from 1' to 5' in
PLUMAS COUNTY. 49
thickness. The pebbles are usually small, from 1" to 4" in diameter.
There is but little doubt that all the isolated gravel patches were
originally connected with the large Meadow Valley area of lake
gravel.
Of the Neocene auriferous gravels there is an exposure at the west
edge of the lava cap which covers Chaparral Hill. This exposure was
worked by the hydraulic method and was known as Fales Hill. To
the southeast of this, on the same ridge, are other exposures of these
&ame gravels, some of which have been worked.
Two miles northwest of Spanish Ranch, at an elevation of about
4600', is the old hydraulic mine of Bean Hill, containing quartz
gravels of the oldest prevolcanic epoch. The Pine Leaf channel, two
miles north of Spanish Ranch, has been traced northwesterly for
about a mile. The channel is 200' wide, the gravel 4' thick, and it
yielded about $1.50 per yard.
TAYLORSVILLE MINING DISTRICT.
The most important mineral in this district is gold, but some copper
is produced as a by-product. Nearly all the gold has come from veins
containing auriferous pyrite, found in the southern portion of the
district in what is known as the Crescent Mills belt of quartz mines.
Taylorsville is situated a little north of the central portion of
Plumas County. It is about seven miles by stage northeast of
Crescent Mills, a station on the Indian Valley Railroad, and about
twenty-nine miles by stage southwest of Susanville, county seat of
Lassen County.
Owing to heavy precipitation of rain and snow during the winter
months the condition of the roads is poor, but during the warm dry
summer the roads are quite good. Taylorsville has an elevation of
3550^
The ridges surrounding it are well covered with timber, chiefly fir,
spruce, tamarack, yellow and sugar pine, and a liberal supply of
underbrush covers the slopes.
Gold is produced both from drift and placer mines. There is a
deposit of pyprhotite a mile and a half south of Taylorsville, but it
has not been exploited.
Indian Creek, and Montgomery Creek, one of its tributaries, assure
a plentiful water supply to the district.
History of mining.
As early as 1850 prospectors found their way into Indian Valley.
Mining claims are more or less distinctly grouped in two belts, the
Crescent Mills belt and the Genesee belt. The southern end of the
Crescent Mills b^It lies southwest of Taylorsville and practically all
the mining in this district has been done there.

Topography.
The district lies in the Grizzly Mountain section of the Grizzly-
Mountain block, the latter extending from the Diamond Mountain
block to the main crest of the Sierras. The Grizzly Mountains have
ft well-marked crest line and escarpment, which presents a steep slope
of over 3000' to the west end of Genesee Valley. The crest line sinks
and curves toward the northwest, running to Taylorsville, where it
disappears in Indian Valley. A small notch is cut by Montgomery
Greek across the north end of Grizzly Mountains, where it flows into
Indian Creek, about two miles southeast of Taylorsville. The latter
borders the district on the northeast edge and with Montgomery
Creek and Houghs Creek comprises the drainage system of the
district.
Geo^lo^y.
In the southeastern portion of the district is a large exposure of
Hull meta-andesite, trending generally northwest, in which there is
an exposure of Mormon sandstone about one-fourth mile wide by one-
half mile long in the northern portion. West of this Hull meta-
andesite is meta-rhyolite, trending generally northwest with a deposit
of Grizzly formation in contact with it on the west. Two miles south
of Taylorsville, a lens-shaped mass of serpentine has been intruded.
Further south a larger mass of serpentine cuts through both the
Taylorsville formation and the Grizzly formation and into the meta-
rhyolite. On the west this serpentine is in contact with Taylor meta-
andesite. Southwest of Taylorsville is a body of granodiorite, narrow
at the ends and about one-half mile wide in the middle, trending in a
northwest-southeast direction for nearly four miles in contact on the
west with Arlington formation. There are three rhyolite dikes about
two miles to the west of Taylorsville at the contact between Taylor
meta-andesite and the Taylorsville formation, and three cutting the
terpentine which lies about two miles to the south of TaylorsvlUe.
Two small exposures of Hosselkus limestone are seen west of Little
Grizzly Creek, in the Hull meta-andesite. In the Tant meta-andesite
there are two exposures of Hardgrave sandstone, one lying on the
contact with the meta-rhyolite and the other just to the northeast of
it. Three exposures of Thompson limestone are seen, two in the
Mormon sandstone and one just to the south of the contact between
the Mormon sandstone and the meta-rhyolite.
The pre-Silurian meta-rhyolite is the oldest formation in the
district. It is a massive gray siliceous rock with occasional incon-
PLUMAS CaUNTT. 51
spicuons phenocrysts of quartz in a uniformly jSne, compact ground-
mass. Gn the lower slope of Grizzly Mountains it has a decided
seMstose structure, due to the compression and consequent shearing.
The Grizzly formation of Silurian age is a gray, well-defined but
thin-bedded quartzite overlain by lentils of limestone and inter-
stratified with shaley, often siliceous slate (argillite) having irregular
cleavage. The coarser beds of quartzite contain small pebbles of
rhyolite.
The Taylorsville formation of Devonian age is composed of fine
sediments, chiefly slates and thin-bedded sandstones. Near the
middle are Well-defined beds of light-colored quartzite, and at the
base is locally a fine conglomerate. The general dip of the formation
is to the southwest.
The Arlington formation, belonging to the Calaveras group of
Carboniferous age, is made up chiefly of fine, gray thin-bedded sand-
stone, with some shale in part silicified and a few beds of con-
glomerate. Along Houga Creek it is bounded by granodiorite. These
bordering igneous rocks are younger and either penetrate or over-
flow it.
The Taylor meta-andesite, of the Calaveras group of Carboniferous
age, is a decidedly green rock. Where not much altered it is
porphyritic with crystals of augite. It is apparently an eruption
interstratified with Carboniferous rocks.
The Hull meta-andesite varies from greenish to reddish. Much of
it is in well-defined sheets representing lava flows. The fact that it
penetrates the Mormon sandstone indicates that its eruptions took
place near the close of the Jurassic.
The serpentine in this district is a typical green serpentine, varying
greatly in composition. The most abundant form is composed almost
wholly of a light-colored pyroxene with a small amount of dark
green hornblende. The serpentine intersects the meta-rhyolite and
all Paleozoic rocks, but does not come in contact with later sediments.
In turn, it is cut by quartz diorite, and dikes of the later rhyolite,
indicating that it belongs among the first eruptions of the late
Jurassic or early Cretaceous.
The rock included under the head of granodiorite is a light-colored
and for the most part medium-grained rock resembling granite, com-
posed chiefly of plagioclase feldspar and quartz. It is of late Jurassic
or early Cretaceous age.
The dike rocks of the late Jurassic or early Cretaceous vary in color
from light gray to pale green and reddish-brown. Small pheno-
crysts of quartz are always present, but they are rarely porphyritic.
52 MINES AND MINERAL RESOURCES.
The Hosselkus limestone, two small exposures of which appear
directly in contact with the Hull meta-andesite, is of Triassic age. It
is a dark blue on fresh fracture, but weathers light gray, and contains
a few veins of white calcite.
The Hardgrave sandstone is of Jurassic age and only two small
exposures are seen in the district. It is red or gray in color, varying
irom a fine shaley sandstone to conglomerate, and is almost wholly of
tuffaceous character.
The Fant meta-augite andesite is a greenish to reddish brown rock,
more or less porphyritic, sometimes with augite, but often with
plagioclase phenocrysts. The groundmass is made up of small
crystals and grains of feldspar, augite and magnetite, generally with
some amorphous matter. It is of Jurassic age. That portion lying
on the lower slope of Grizzly Mountains includes fragments of Hard-
grave sandstone, showing it to be a volcanic effusion in the interval
between the deposition of the Hardgrave sandstone and the Thompson
limestone.
The Thompson limestone, of Jurassic age, is gray and somewhat
shaley. On the lower slope of Grizzly Mountains are three isolated
ledges lying along a line extending nearly east and west. This is
later than the Fant meta-andesite to the west and seems to conform-
ably overlie the Mormon sandstone.
The Mormon sandstone, comprising a curved area on the lower
slopes of Grizzly Mountains, is chiefly gray.
Mineral deposits.
The metalliferous deposits in this district are confined largely,
through not wholly, to the igneous rocks, but they are not definite
contact deposits. They are in more or less well-defined quartz veins,
usually running parallel to the course of the belt, but in a few cases
small veins run nearly at right angles to the others. The ore belt
itself is in the narrow mass of granodiorite southwest of Taylorsville.
The ore is auriferous pyrite, sometimes in small bodies, but generally
disseminated in the narrow strip of sheared rock of the partially
formed vein in which there is usually some quartz. The pyrite is
nearly always changed to limonite, setting the gold free.
Two-thirds of a mile south of Taylorsville at the old Pettinger
mine, a small imperfect vein in the Taylorsville slate is impregnated
with carbonates of copper, generally green but sometimes blue.
A mass of pyrrhotite, one and one-half miles south of Taylorsville,
lies in a narrow strip of sheared sandstone, running north and south
near the horizon of the Montgomery limestone, but the largest body,
ybout 10' in thickness, is at a point where the sheared sediments end
against serpentine.

MINES AND MINERALS.
CHROMITE.
In the Quincy District three prospects were noted which had not
made any production up to the end of July, 1918.^
L. Eddelbuttel and Thomas Hughs of Quincy had two locations in
the inaccessible canon of Middle Fork of Feather Eiver.
J. L. Foisie of Quincy had one undeveloped prospect three miles
west of Spanish Peak Sawmill.
J. Gifford of Meadow Valley had two locations which were under
lease to F. E. Young and A. L. Smith of Quincy. Two men had
started prospecting late in July, 1918, and hoped to produce a carload
of ore.
Jitney Chrome Mine.^ Owners, McCarty and Hughs, Quincy.
Located in a very inaccessible part of the Quincy District on the east
bank of Middle Fork of Feather River, in Sec. 14, T. 23 N., R. 9 B.,
ten miles southwest of Quincy. The group comprises two claims
which were operated under lease by the Union Chrome Company.
The principal orebody was a lens of solid chromite 6' wide in the
center, and 80' long ; the southern 20' of the orebody had been offset
a distance of 5' by a fault. This lens had a northerly strike and
pitched 80° W. It was said to carry 46% CrgOg.
It was developed by an open cut. At the end of July, 1918,
175 tons had been mined and there was said to be no more in sight.
The trail from this property raises about 3000' in ascending the
mountain to the end of a road which, in turn, drops 3000' to Quincy
in a distance of about six miles.
Valley View^ chrome property is near Greenville. It is owned by
W. P. Boyden and Fred Koenig of Greenville and was leased on
royalty to A. E. Vandercook of Oakland, who is reported to have
transferred his lease to the Western Ores Company.
It is said that one car of ore was shipped in 1916 and two cars in
1917, averaging 32% CrgOg. The property was idle in July, 1917.

along the lode. It is situated on the ridge northeast of Last Chance
Creek and there is a good stand of pine timber on the property.
The claims are prospects, located in 1914, and only a limited amount
of prospecting has been done.
Development work at time of visit in 1913 consisted of a tunnel,
40' long on the Copper Queen and a series of shafts 10' to 20' in depth.
The deposit consists of a quartz vein capped with iron gossan
between walls of diorite. It averages 2' in width with a maximum of
4' ; strikes northwest, dips vertically and has a proven length on the
surface of 3000'. The ore contains chalcopyrite and bornite.

This property consists of five claims: the El Dorado No. 1 and
No. 2, Bear, Wild Cat and Napoleon, situated on the timbered ridge
east of Last Chance Creek. It covers a length along the lode of 3000',
and is 70 acres in area.
The property was discovered in 1909 and has been worked off and
on since that date. One car of ore, assaying 56% copper, was
shipped.
Development work consists of a crosscut tunnel 60' to the vein,
cutting it 50' below the outcrop, and a drift easterly for 155'.
The deposit consists of a series of quartz fissure veins in granite.
The ore /is basic, containing chalcopyrite, bornite, malachite, and
azurite. The main vein has a maximum width of 5' with an average
of 3', strikes east, and dips 55° N., with a proven length on the sur-
face of 3000'. There is an E.-W. vein 500' south of the main vein
with a tunnel on it 25' long, which shows the vein to be 5' wide,
and the ore to average 5% to 6% copper.

56 MINES AND MINEBAIi RESOURCES.
The property contains 154 claims, of which 23 are patented. There
are two groups, known as Engels and Superior mines, the latter being
two and one-half miles south of the Engels mine. The lode is covered
for about three miles; there are good outcrops on many of the claims,
and the entire area is believed to be well mineralized. In 1917 the
company claimed an ore reserve of not less than 3,000,000 tons of ore
above the tunnel levels, and total probable reserves of not less than
10,000,000 tons of 2^% copper ore.
Diller mapped the country rock in the vicinity as granodiorite.
Rogers describes the rock in which the ore occurs as norite-diorite.
He notes granodiorite, some of it rich in biotite, as a differentiation
product of the diorite. Graton and McLaughlin describe it as ' * noritic
in character, being composed of plagioclase and slightly subordinate
amounts of orthorhombic and monoclinic pyroxenes, and biolite."
They observe that it is *' probably a basic differentiate of the great
Sierra Nevada batholith of granodiorite.''
Turner and Rogers described the Engels mine deposit as a mag-
matic segregation. According to Turner, the ore occurs disseminated
through the fresh diorite, in which most of the fractures are post
mineral. The metallic oxides and sulphides, as described in their
article, appear to have crystallized out from the magma in the same
way as the feldspar hornblende, pyroxene and biotite. Quoting
Turner, *'the ore minerals are largely interstitial between the silicate
minerals, and thus later in crystallizing out.'' In the Superior deposit,
on the other hand, the ore minerals are largely deposited along joint
planes, and are clearly of secondary origin-. These writers, particu-
larly Professor Rogers, came to the conclusion that the development
of chalcocite and some covellite by replacement of bomite is the work
of ascending, heated alkaline waters.
Graton and McLaughlin, as the result of later studies of the deposit
and of many thin sections of the ores, took issue with the above
findings. They concluded that:
**1. The ores, instead of being magmatic in the sense that they were
initial constituents of the dioritic rock in which they occur, were
introduced after the rock had solidified and had suffered notable
dynamic and chemical changes, and constitute replacements formed
under pneumatolytic and hydrothermal conditions * * *.
**2. Although the possibility of formation of a small amount of
chalcocite from ascending solutions can not be absolutely excluded,
no satisfactory evidence of chalcocite of replacement origin formed
in this way, i. e., by upward secondary enrichment, has come under
our observation. Most of the chalcocite and all of the covellite at
Engels unquestionably result from replacement of earlier sulphides
PLUMAS COUNTY. 57
through the agency of descending meteoric waters and a competent
explanation for all of the chalcocite is to be found in normal down-
ward enrichment. ' ' The question of the origin of the rich chalcocite
ore is of the utmost importance, as when once determined, it will
throw much light on the future of the mine.
The deposit was discovered in the middle '80 's by Henry Engels.
At that time it was so remote from the railroad that production was
nearly out of the question. Nevertheless, some high grade ore is said
to have been shipped from the Superior group to Swansea. Assess-
ment work was intelligently done, so that known ore reserves grew
larger each year. In 1894 the Engels group, according to the State
Mineralogist's Report, comprised three claims, developed by three
tunnels, the longest then reported 425' long. In 1912 the same group
was proven to a depth of 250', and the copper belt was described as
being 1800' wide with a gossan outcrop 300' wide and 2000' long.
Over 4000' of development work had been done in five years past on
the Engels group, but only about 500' on the Superior group.
In 1911 a 500-ton blast furnace was built, but was never operated
on account of government objection to fumes. Early in 1914 the
company was reorganized and a minerals separation flotation plant
capable of treating a maximum of 225 tons daily, was built at a cost
of $50,000. This plant was put in operation in February, 1915, and
gave the mine the distinction of being the first to depend entirely on
oil flotation for the recovery of copper sulphides. This process gives
a much higher grade concentrate than ordinary water concentration,
because of the presence of iron oxides in the ore. An extraction of
77.6% was obtained from an ore said to average 3.8% copper. The
concentrate that year averaged 33.82% copper. In ten months,
8,724,494 pounds dry concentrate were made. Development cost 67^
a ton, mining 40ff, treatment $1.20, marketing $1.14 and general
expense 78fJ. The capacity of the mill was doubled late in 1915.
An electric plant with a maximum capacity of 400 horsepower was
built and electricity was brought in over a line two miles long. This
proved inadequate and had to be supplemented at once by distillate
engines. The property at this time was twenty-six miles from the
railroad and there was a grade of 1800' in the last two and one-half
miles to the mine. The concentrate, carrying 5% to 6% moisture,
had to be sacked and lowered on the tramway to the lower terminal,
where it was picked up by trailers drawn by a Holt caterpillar
tractor. This delivered it over the worst of the road to trucks which
hauled it to Keddie for shipment to the Garfield smelter.
During 1916 the Indian Valley Railway (broad guage) was built
twenty-two miles from Paxton to the mine at a cost of $500,000.
58 MINES AND MINERAL RESOURCES.
This road is owned principally by the Engels Copper Mining Com-
pany. The same year the Great Western Power Company built at a
cost of $150,000 an electric transmission line thirty-eight miles long
from its Butte Valley plant to the mine.
Over 14,000' of development work had been done to the end of
1916 in the Engels group, and during that year the Superior group
was also opened with very encouraging results. The ore bodies have
been opened by tunnels and winzes, and further prov(^n to a depth of
500' below the lowest working level by diamond drilling. The
oxidized zone is covered in most places by 6' of soil, but where bare
it shows a leached rock stained by malachite, limonite and chryso-
colla. The oxidized zone is irregular in its lower limits, merging
into mixed chalcocite and carbonates, the richer parts of which have
been mined but are now inaccessil^le. Below this, is the zone of
sulphide enrichment which has yielded considerable chalcocite carry-
ing 16% to 20% copper. This zone was 25' thick and dipped gently
southwest. This ore gives place to bornite at depths of 100' to 130',
with some stringers of chalcocite extending deeper. The ore body
has an average width of 40' and maximum of 150'. It strikes N.
80° E. and dips 8° SW. Six tunnel levels have been opened. No. 1,
the highest, was run 30' with a 50' raise; No. 2, 810' with 320' of
crosscuts and a 75' raise; No. 3, 180' with 110' of crosscuts; No. 4,
1500' with 970' of crosscuts and 260' of raises and winzes, with a
stope 400' long, 40' wide and 10' high in 1916 ; No. 5, drift 1110' with
650' of crosscuts, 200' of raises and a stope 300' by 40' by 70' ; and
No. 6 the lowest level. Recent work has been on levels 4, 5 and 6, but
the extent to which these have been carried to date is not known.
The ore body has been proven on the surface and in the upper levels
for 1500' on the strike, and had been opened to a vertical depth of
700' at the beginning of 1919.
In the Superior group, developments have been equally gratifying.
A main tunnel and shaft are being driven, and it is planned to sink
the latter to a depth of 1000'. A stope 500' long was started early in
1919. The ore in the Superior occurs chiefly along joint planes and
there are occasional small bodies of high grade.
Pyrite is notably absent from the Engels ore and has been men-
tioned as occurring at only one place in the Superior. This accounts
in large measure for the high grade of copper concentrate obtained.
The ore is now chiefly bornite averaging 2.3% copper as milled,
giving a concentrate carrying about 25% copper. The total mill
capacity of the two plants was said to be 1500 tons a day in April,
1919, and subsequently it was planned to increase the capitalization
of the company and bring the mill capacity to 2000 tons a day. The

60 MINES AND MINERAL RESOURCES.
The property was discovered in 1905 and has been worked off and
on since that time. In 1915 it was under bond and lease to J. F.
Cutler and four men were working, two on top and two in the mine.
It is developed by a vertical shaft 120' in depth, from the bottom
of which drifts have been run 25' south and 50' north. There is also
a crosscut tunnel 125' long.
The deposit is a fissure vein filled with quartz and schist cutting
the diorite, and containing bornite, chalcopyrite and some magnetite.
The ore runs 3% to 5% copper with about $1.20 gold and some silver
values. Wall rocks of the quartz vein are altered to actinolite schist.
The vein has a maximum width of 15', averages 4', strikes N. 20° W.,
dips 85° W., and has a proven length on the surface of 3600' The
oxide zone has a depth of 35' and is capped by an iron gossan.
Oil was being used for fuel in 1917, and a 25-horsepower steam
hoist, a 40-horsepower boiler and a No. 5 Cameron pump are included
in the equipment.

Location: Sea 25, T. 24 N., R. 16 K, 9 miles north of Chilcoot (W. P. Ry.)
by Chilooot and Last Chance road. Elevation 6250'.
This property consists of 160 acres of patented ground, covering a
length along the lode of 3000'. The claims are the Mohawk, and Last
Chance, both situated on the west slope of Adams Mountain, and
carrying a plentiful stand of pine timber.
The deposit was discovered in 1905 and has been worked off and
on since then. It is now under lease to F. J. Channing and C. N.
Shaffer of Reno. In 1913 there was shipped to the Western Ore
Purchasing Company a daily production of about eight tons, which
runs 6% copper. The total production to date has been about
1000 tons.
The vein has been developed by a 180' shaft inclined at 80°, on
which there are three levels: the 50', with a drift 125' north, the
120' with a drift 125' north and the 180' with a drift 65' north, and
about 240' of crosscuts. The vein has been stoped from the 120' level
north to the tunnel level.
The deposit consists of a series of parallel veins cutting a granite
formation. The main (Mohawk) vein, has a filling of quartz and

granite, and granite walls. The maximum width is 10', average 4'.
It strikes N. 20° E., dips 80° W., and has a proven length on the
surface of 3000'. One ore shoot developed 30' long and averaged 4'
in width. The ore goes 6% to 8% -copper, 40^ gold and 2 ounces
silver. There is some molybdenite associated. A northwest-south-
east vein, with a dip of 50° E., was cut on the tunnel level. It lies east
of the main vein, but probably intersects it in depth. The oxidized
zone has a depth of 50'.
Equipment comprises an 80-h.p. boiler, IngersoU-Rand compressor,
a 25-h.p. single-drum hoist and a Knowles pump. Fourteen men were
employed in 1917.

Location: Sec. 25, T. 24 N., R. 16 E., 8 miles north of Chilcoot, 10 miles by
wagon road north of Chilcoot station on W. P. Ry. Elevation 6500'.
This property consists of 8 claims — the Last Chance Nos. 1, 2, 3,
4 and 5, King George, King Edward and Copper King. There is a
total of 160 acres, covering a length along the vein of 4500'. It is
situated on the slope of the ridge northwest of Mt. Adams. Sugar
pine and spruce are plentiful.
The property was discovered in 1909 and has been worked inter-
mittently to date. Six men were working in 1917, three on top and
three in the mine. It produced 90 tons of 6% to 8% copper ore.
Development work consists of a 104' shaft on Last Chance No. 1,
from the bottom of which drifts run 38' southwest and 104' northeast.

The 21 locations comprising the property, together with the Shoofly
Ranch, patented, on which the first discovery of copper ore was made,
extend in a general northeast direction, parallel with the strike of the
underlying schists.
Besides numerous surface cuts, the principal development on the
property is a tunnel 80' long crosscutting the strata. It enters on the
bank of Indian Creek within the boundaries of the Shoofly Ranch.
The copper ore occurs disseminated in a quartz schist, with a nearly
vertical dip ; with clay slates to the west and a series of igneous rocks,
chiefly porphyrites to the east. The copper-bearing vein belt is

believed to follow the center line of the locations with an average
width of 80', and a copper content given as nearly 2%. The ores
noted are generally bornite, with blue and green carbonates, the latter
constantly forming at the surface from a leaching action. It occurs
in minute sheets and lenses between the much contracted laminations
of the schist, which everywhere exhibits the action of compressive
force, and in general structure resembles strikingly the copper-
bearing schists of Calaveras County.

The property consists of 400 acres, 200 of which are patented. The
patented claims are the Bullion, Bullion Extension, Copper Center,
Copper Center Extension, Rob, Rob Extension, Walker, Walker
Extension, Valley View and Valley View Extension. ' The holdings
extend from the top of the mountain, south to Little Grizzly Creek,
and the main workings are situated on top of the ridge about two
miles south of Mt. Ingalls, at an elevation of 8000'. There is good
timber on the property.
Walker Brothers have held the property for the last five or six
years. The mine has been favorably reported on by numerous engi-
neers and the controlling interest has been purchased for a large sum.
The company was pushing development work late in 1918.
The vein has been developed by a 50' shaft and two 75' north and
south drifts on the vein. A crosscut has also been driven 80' through
the vein from the bottom of the shaft, and there are 300' of open
cuts on the surface.
The vein is a quartz vein 6' to 8' in width in an altered zone of a
maximum width of 80' impregnated with sulphides containing copper,
silver and gold. The ore of the quartz vein encountered in the shaft
at a depth of 15', contains basic sulphides, bornite, chalcopyrite and
tetrahedrite (gray copper). This shaft was inaccessible at time of
visit, but the vein walls are said to be diorite. The strike is north-
west and the dip is 65° NE. Ore on the dump is reported to run 7%
to 12% copper, with unknown amounts of gold and silver.
The mine is equipped with a sawmill, 7 thousand feet capacity, a
15-horsepower boiler and hoist. A new 60-horsepower boiler and
engine and a compressor were installed in January, 1914. There are
three houses, including a new bunkhouse.
The nearest mines are the Gruss and Mother Lode (Caiman).
64 MINES AND MINERAL RESOURCES.
High grade ore assaying 12% copper was struck in October, 1915,
in the 150' drift from the 125' level. Construction of a 4600' aerial
tramway, a 100-ton flotation plant, and ore bins was progressing.
Prospecting with diamond drills has proven an ore body for a dis-
tance of 200' in the Walker mine. Assays average 7.20% copper,
$1.11 gold and 2.7 ounces silver. This is an average of assays taken
each five feet for 200' in a hole put down from the 65' level 250'.
Further drilling is under way from the 125' level. Reserves are
estimated at 20,000 tons. A crosscut at the 125' level averaged 6%
to 8% copper and 3 to 4 ounces silver. A second crosscut now in
400' will open the ore 75' below the shaft bottom and 800' in. The
Leschen aerial tram, under construction, operates by gravity, and will
handle 250 tons in 16 hours.
A new flotation plant was completed in October, 1916. It had a
capacity of 85 tons daily but was being enlarged to an ultimate
capacity of 200 tons. The plant consists of Blake crusher, Marcy
ball mill. Dorr classifier, Callow cells. Dorr thickener and Oliver filter.
Daily output in summer of 1918 was said to be 18 tons of concentrate,
and a recovery of 95% copper and 75% gold and silver was claimed.
Electricity is used for power. Concentrate is shipped to Tooele.
Cost per ton for milling during the first half of 1918 was said to be
$2 a ton.

About one-half mile west of Flournoy 's the mountain is covered by
mining locations, comprising the Williams group. On this mountain
the whole outcrop appears to be heavily mineralized by iron and
copper in the form of oxides, carbonates and sulphides. So little
development work has been performed that no estimate of the worth
of the claims can at the present time be made, but it is doubtless the
outcrop of an immense mineralized dike.

The Bellevue Mining Company's holdings include the Louise,
Feather Fork Gold mine, Chaleedonia, National, Eureka Consolidated,
Blackie and Last Chance properties. The total area is 2000 acres
with a length along the channel of three miles. It is located across
a lava covered ridge on the steep west bank of Slate Creek.
Work was carried on through the 400' Thistle shaft from 1890 to
1896, but when the shaft was flooded in 1901 a lower tunnel was
started.
Development work consists of a 5400' tunnel, 8' by 8' in the clear,
costing $14.50 per foot, not including overhead charges. Working
upstream from the end of tunnel, 3000' were explored, 1300' breasted,
and downstream 900' explored and 600' breasted. A new tunnel will
start 4811' from the portal of the main tunnel, running N. 27°, 16' W.
3060' to reopen the most northerly workings, which are about a mile
south of Thistle shaft. Width of gravel deposit is 1400', prospected
by tunnel in line with main tunnel. Area worked is 1700' by 120'.
Tailings go into Slate Creek.
The deposit is free Neocene channel gravel, coursing southwest,
containing large quartz boulders. Country rock is amphibolite and
slate ; the bedrock is slate. The gravel and sand is 150' deep, capped
with andesite, the pay gravel being 120' wide and 4' deep, including
G" of bedrock. Several faults were encountered j 600' north of the

tunnel a vertical fault had a downthrow of about 10'. At a point
1000' north of the first fault, a second occurred, the fault plane
dipping northwest 30° with a downthrow of 30' to the north; and
GOO' further there is a fault striking northwest and dipping 45° SW.
The workings are timbered throughout with round timbers at 40^,
7' caps 4^ff, lagging 3^^. Forty men were employed in 1915, six
outside; miners getting $3.50 per day, muckers $3.25. Two to six
cars of one cubic yard capacity per man per day were produced ; $4 to
$10 a cubic yard is the total operating cost. Transportation charges
are $1.25 per 100 pounds from Marysville. The mine is being worked
at the present time, but with a small force only, on account of war
conditions.

This property consists of 120 acres of patented ground, charac-
terized by broad ridges and a wide ravine at the head of the creek.
It was originally located by Bushman in early days. In 1911 and
1912 it was under bond to Capt. Henry Adams, but it has been idle
since March, 1912.
Development consists of a 1200' tunnel, 600' of which was run in
early days. A vertical shaft 133' to bedrock was sunk by Adams,
passing through alluvial wash composed of slate, decomposed clays,
etc. The quantity of gravel worked in early days is not known, but
the last company handled very little.
The so-called 'Old ChanneP gravel is really an alluvial wash com-
posed of angular fragments of slate and vein quartz that have been
derived from the disintegration of the surrounding slates, which are
cut by numerous stringers from a few inches up to veins 8' in width,
with heavy gouge and well defined walls. The width of pay gravel
is 40' with a depth of 18" to 3'. The deposit ranges from 30' to 100'
in depth, is free and has no large boulders but contains fragments of
slate 1' to 2' in length, lying on slate bedrock. A large amount of
water is encountered, too much to handle by pumping, and all of the
workings have to be timbered.
The equipment consists of a Fairbanks-Morse gasoline hoist and a
gasoline driven American Well Works pump, good houses and barn.

The country rock is slate and schist, the deposit being in the former
old river channel of the North Fork. The course is north, with a
depth of 40' of quartz and greenstone gravel with large boulders.
The bedrock is slate. This channel can be traced southward where it
crossed the North Fork above Seneca and has been encountered and
worked in the Glazier, Cameron, Scott, San Jose, Wisbein and Sunny-
side mines. The pay gravel is about 6' deep above bedrock. Above
this occurs a false bedrock of cemented sand upon which is said to lie
another 5' of pay gravel. No large amount of water encountered.
Equipment consists of pumps, houses and blacksmith shop.
Power can be had from North Fork Feather River under a head of
400', 20" in season.
The Pliocene, on the same channel, is an adjoining mine.

This property includes five claims, namely, the Dutch Hill placer,
the Barker Hill placer, the Banner placer, the Barker Hill quartz, and
the Cummings Hill quartz claim. It is situated on top of a high
ridge which lies west of the North Fork Feather River and covers
4400' along the old channel.
The deposit was worked from the early '50 's until 1873 as a drift
mine. In that year the small claims were consolidated by C. W. Read

of Sacramento and a thirty mile ditch was put in from Lassen Peak
hi a cost of $500,000. This company is supposed to have tak^^n out
about $200,000 from the hydraulic cuts. After hydraulic work was
stopped, drifting was again taken up but after $175,000 had been
taken from 24,000 cubic yards of gravel, the mine was closed down.
A few years later the Savercool Brothers reopened the mine and
worked it continuously for twenty years by drifting and hydraulick-
ing, taking out about $200,000, $100,000 from the hydraulic pits and
$100,000 by drifting, the gravel running about $10 per yard. It has
now been idle for some years.
The deposit is composed of gravels of Neocene age cemented in
places and containing some large boulders, on bedrock of slate, sand-
stone and quartzite, with a basalt capping. The total overburden is
325' of gravel and lava. The course of the channel is north, and the
width of pay gravel is 1600'.
There are also two quartz veins on the property. The Barker Hill
vein, opened by a tunnel 200' in length, is said to have averaged $4.50
per ton. It strikes northwest and dips 60° southwest. The Cum-
min gs Hill quartz vein, discovered in working the Cummings gravel
deposit, was never assayed, but prospected well in the pan. It strikes
northwest and dips southwest. Below these veins the gravel was
very rich in rough quartz gold. The channel has been faulted at two
points; the lower fault strikes north and the throw is said to have
been 800' vertical, while the upper fault strikes east, with a throw of
200'. The channel between for 2500' is unbroken.
Thirty inches of water are obtained under a head of 90', but steam
is used for power. The cost of mining is about 95ff a cubic yard.
Adjoining properties are the San Jose and Sunnyside.

The property consists of 53 acres, with a length along the channel
of 4000'.
A main shaft was sunk 107' deep and from the bottom of it drifts
were run north toward Emigrant Hill, a distance of 3000'. The
channel was worked for a width of 40'. This gravel is said to have
averaged $20 per day per man. The ground was heavy and had to be
closely timbered, and a large amount of water was encountered.

This property includes two claims, with an area of 40 acres. It is
situated on Besty Gulch, tributary to Spanish Creek.
The mine was worked in early, days by hydraulicking, and the
ground is said to have been entirely worked out.
The deposit was old channel gravel, some rounded gravel and local
wash, on bedrock of slate. There is 180' of gravel to bedrock, free
and with very few boulders. The width of pay varied from 20' to 50'
and it had a depth of 3' above bedrock.
The deposit was breasted by an 800' tunnel through the hill and an

There are eleven claims, total area 1186 acres. The channel on
this property is in line with and said to be the continuation of, the
La Porte channel, which was worked for twenty-five years up to 1914
on the south, in the famous Belle view drift mine. The latter property
is reported to have made an annual average output of $750,000.
Both rims of the channel are well defined. The bedrock is slate
and there is an overburden of from 150' to 1000' of andesitic material.
The property has a good stand of timber on the higher ground and
the water supply is said to be ample during the entire year. Exact
data on the depth and width of channel are not available.
74 MINES AND MINERAti RESOURCES.
Development work done lately indicates the presence of two
channels, one crossing Onion Valley Creek about one-fourth mile
west of the mouth of Bird Creek, and the other at the mouth of
Cement Creek; some think that the channel forks on this property,
one fork continuing south to the Belleview and La Porte, while the
other branch connects with the Grass Valley channel.
W. de Varilla, in a report made in January, 1914, advised running
a tunnel to strike the pay gravel in the channel at the lower end of
the property to take advantage of gravity. He estimated a tunnel
]000' long costing about $9000, would be required, and that the total
cost of opening the property would be about $15,000.

The property consists of a patented placer claim, 160 acres in area,
following the channel for three-fourths of a mile. It was located by
McMillan in 1884, and is situated on the west bank of the North Fork
Feather River, with a steep slope to the top of the ridge.
It is developed by a tunnel 1450' long. There are 800' of raises,
tour raises showing gravel lying on a steep rim. The tunnel is now
in 125' beyond the last raise, and is expected to reach the channel in
a short time. It passes through Calaveras slates and costs about $10
per foot to drive.
The deposit is composed of old river channel gravels, quartz gravel,
free 'ironstone' and boulders, following the course of the present
river, 250' above it. The depth of gravel varies from 18' to 30'

There are two groups of claims, the Morning Star and North Star,
containing 760 acres, in this property. They lie on the north side of
Blue Nose Peak, which rises to an elevation of 7300'.
Development work consists of two tunnels, a crosscut tunnel 250'
long passing through 50' of slate and 200' of lava, and a main tunnel
driven 1600' from the north end of the Morning Star claim. A winze
put down 65' from the end of the crosscut was abandoned on account
of water. The main tunnel follows the course of the old channel,
300' being driven through schist; 800' from the portal, a 30' raise
encountered gravel and 15' x 12' x 6' was stoped. From this stope
another 20' raise was put up and ground 40' x 40' x 60' was stoped,
1000 cars yielding $1300. From the top of the last stope a drift was
run 250' to the east, the first 50' in gravel, the rest in country rock
and 3600 cubic yards were worked. Another tunnel has been started,
200' below the crosscut tunnel.

This property comprises 200 acres of locations, with an undeter-
mined length along the channel of approximately 4000'. It is situated
in a comparatively wide ravine at the head of several creeks.
All of these claims, worked in early days as hydraulic and drift
mines, were consolidated in July, 1913. The new company planned
to start a tunnel from Litle Black Hawk Creek, on the Keystone
claim, which is expected to cut the Jackass channel 200' in. This
tunnel can also be extended to drain the Newtown Flat channel.
Numerous old tunnels have been run, including the Jeffery tunnel,
700' long. There is a new shaft, 90' deep, on the Missing Link.
The deposit consists of water- worn gravel and a few large boulders
under a capping of 75' of clay, gravel and debris. It lies on a bed-
rock of slate, and the channel is supposed to course southwest. A
large amount of water was encountered. As exposed in the Emigrant
Hill hydraulic workings, pay gravel was 60' to 70' wide and from

This property embraces the following 670 acres of placer locations :
Hampton Placer, 180 acres; Willow Placer, 90 acres; California
Placer, 160 acres; Pacific Placer, 160 acres; and Alder Placer, 80
acres. The length of channel covered is said to be two miles. It is
situated on the east side of Nelson Creek from the creek to the top
of the ridge.
The present owner located the group in 1879. It was under bond
to the Continental Mining Company at one time, but reverted to the
original owner in 1912. Two men were working in 1913. The pro-
duction to date has been about $3000.
Development work consists of a 180' tunnel through gravel and
pipe clay which cost about $10 per foot, a 260' tunnel in slate costing
about $5 per foot, and two shafts, 99' and 80', both through gravel
and pipe clay. The tunnels are timbered. Twenty feet of gravel
600' X 200' has been hydraulicked.
The deposit is supposed to be on the old *Blue Lead River Channel.'
It is made up of tree quartz gravel with medium-sized boulders on
slate bedrock. The channel courses south and is capped with 600' of
lava. A good-sized flow of water was encountered. The pay gravel
is 1000' wide and has a depth of 90' which it would pay to hydraulic.

This property consists of 800 acres of patented ground and 1000
acres held by location. The claims are located for a distance of five
miles along the supposed course of an old channel. The steep caiion
of the Feather River and also low ridges and wide alluvial deposits
along Willow Creek make up the surface.
The property is situated on a forest reserve, and a protest was filed
on a portion of the ground which the company abandoned. The river
bars and hydraulic mines were worked in early days. Nine men were
employed at time of our visit.
Work on the five miles of channel has been almost entirely confined
to the Blue Gravel claim, where an incline 250' long was put down
and 500' of drifts were run from the bottom of the incline across the
course of the channel and three raises were put up. No information
is obtainable as to the amount or value of gravel developed. A 200'
shaft, sunk through lavj). is said to have reached the channel, but the
PLUMAS COUNTY. 85
present company has never had it unwatered. A small amount of
gravel has been worked by hydraulicking.
The deposit is old river channel lying on a bedrock of slate, sup-
posed to be the former course of the Middle Fork Feather River.
The gravel is nearly all free. In places it is capped with andesite
and older basalts. A large amount of water was encountered in the
workings.
Equipment consists of houses and blacksmith shop.
There are two ditches of two miles each which supply a small
amount of water under a head of 100'. Labor costs $3.50 per day

This property consists of 119 acres of patented ground, covering a
length along the channel of 2500'. It is situated in a flat arm of
American Valley.
Discovered in 1852 and bought from W. W. Kellogg by the present
owners in 1906.
A number of shafts have been sunk and the channel has been
worked for a distance of 500'.
The mine consists of old channel gravels coursing southwest, said
to be a continuation of the Emigrant Hill deposit. The gravel is
free, being waterworn with angular local wash on bedrock of slate.
There is about 140' overburden of sand and gravel. Large amounts
of water were encountered, too much to handle, with a depth of pay
of 4' above bedrock. It is estimated that there is still 2000' of virgin
ground to be worked, the bedrock averaging $4 per square foot.
The fact that the water can not be handled is a serious drawback.

Kelly has owned this ground for the last 20 years. It has been
surveyed for patent and bonded to W. W. Bobbins, 4115 Helena
street, Spokane, Washington. Good pay was opened up in February,
1914, and four men were working then.
Development consists of a 5' x 6' tunnel, 1000' long, through
quartzite and slate which cost $10 per foot. The last raise put up
through 20' of slates struck a small amount of gravel and another
raise to be put up is expected to encounter the center of the main
channel. A small area of gravel has been worked by an old branch
from the main tunnel. Hand drilling methods are used in working.
The deposit consists of old river channel gravel with a northerly
course, composed of quartz, ironstone' and greenstone boulders.
The bedrock is slate and quartzite. There is a gravel overburden
and different flows of lava, totaling 600'. A quartz ledge was
encountered in a former bedrock tunnel carrying gold and chalco-
pyrite and also some carbonates. No work was done on this vein.
Quartz veins have also been encountered in the present tunnel, but
no assays have been taken. A medium amount of water was
encountered.

This property consists of 160 acres of patented ground, covering a
length along the channel of three-fourths of a mile. It is situated on
the west bank of the North Fork Feather Eiver. The tunnel and
channel are 200' above the bed of the present river. Fair timber
stands on the property.
The mine is developed by an 800' tunnel with a 30' to 45' raise at
the end of the channel. A large but unknown amount of gravel has
been worked from the east rim in old workings. In the old workings
all of the tunnels were too high to bottom the channel, and drifts were
run along the east rim only. From these drifts winzes were put down
and the ground breasted regardless of the large amount of water that
had to be pumped. The gravel stands fairly well. It is breasted and
the large boulders separated by a grizzly in the chutes, then trammed
800' to the washhouse in one-ton cars. The old workings followed
the east rim for half a mile, and the winzes that were sunk as deep as
water would permit never reached the bottom of the channel. The
Peterson crosscut 200' across the channel was 25' above the bottom,
and a shaft put down 18' failed to reach bedrock. The center of the
channel and the west rim are therefore supposed to be virgin ground.
The present workings were also run too high. The main crosscut
will have to be continued, and another raise put up to reach the
bottom of the channel.
The deposit is made up of old river channel gravel on a bedrock of
slate with stringers of quartz in it. The channel courses N. 17° E.
and has an overburden of 600' of gravel and lava. A large amount
of water was encountered. Width of pay gravel is 100', depth 3' to
4', above bedrock. Most of the gold occurs on bedrock. The pro-
duction in the two years of 1913 and 1914 has been $20,000. The
total production to 1913 is said to have been $150,000.
A small amount of water under 300' head is available. The cost of
running the tunnel averaged $10 per foot, and the cost of working
the gravel is about $1 per ton, assuming four cars are produced per
man per day. Three men have been employed for the last three years
during the summer season, and two men will work all winter doing
development work.
There is a blacksmith shop and equipment on the property.

88 MINES AND MINERAL RESOURCES.
This property consists of 105 acres of placer ground and two quartz
claims. There is a total area of 145 acres situated on the flat across
the ridge that forms the west bank of the river back of Seneca, and
it contains good timber.
The deposit consists of surface placers and old channel, supposed
to be a southern extension of Dutch Hill. The bedrock is slate, and
the gravel is lava-capped. A 30' shaft was sunk in ore on a well-
defined quartz vein in slates, developed on the property. A large
dump from the shaft is said to average $8 per ton and is good-looking
oxidized quartz. The vein strikes a little west of north and dips
60° W. The gulch in which the shaft is located cuts across the vein
and is said to have been very rich below the vein. This ledge was
cut 115' below the outcrop by a bedrock tunnel and is reported to
have been 12' to 29' in width, carrying a heavy percentage of
auriferous pyrite and some free gold.
The ground has been owned by Pizzoni for the last 20 years. The
surface placers are said to have been rich.
Assessment work only was being done in 1914. Tunnels aggre-
gating 5000' in length have been run, but all are believed to have
been too high. A large amount of pay gravel was developed on a
bench where breasts are said to have been 100' in width, but no
attempt is being made to open up the deep channel.
Adjoining mines are the Dutch Hill, to the north, and the Sunny-
side to the south, the latter in operation.

' The property consists of Star and Vermont claims (once known as
the New York and Ophir), the Hepsi tailing claim, P. S. damsite
and New York damsite. All of the Star claim is on the northeast
end of the Gibsonville channel, which is a branch of La Porte channel.
Part of the channel on this claim is lava-capped and part can be
hydraulicked. The Vermont claim is cut in two by Whiskey Creek.
PLUMAS COUNTY. 91
It is hydraulic ground. The channel was 800' wide on the adjoining
North America.
Application for permission to build a basket dam on the New York
damsite has been made and the site approved. The site chosen is on
the north branch of Slate Creek. About 1000 miner 's inches of water
are said to be available. There is a storage lake on top of the high
crest, a large reservoir, and a complete system of ditches.
These claims were once held in common ownership with the higher
ground on the North America. The tunnel driven to work the higher
ground was too high to work these lower claims. It is said that
ownership changed before the North America was worked out and
the company had no occasion to undertake mining the lower ground.
The new owners, known locally as the *San Jose Company,' began
hydraulicking the Vermont claim in violation of law, and were
stopped by injunction. They failed to pay their men, who next year,
through their foreman, jumped the claims when the company failed
to do assessment work.
One rim of the channel has been reached by prospect shafts and an
open cut which was driven from the northern branch of Slate Creek.
The bedrock was found to be pitching away, dipping one foot in five,
and the rim gravel was said to carry $1.80 a yard. It has been esti-
mated that it will require 300' of drift to strike the bottom of the
channel. The Hepsidam channel crosses the serpentine belt, which is
held to make probable the occurrence of platinum.
There is a camp with accommodations for 20 men, at an elevation

Holdings consist of 280 acres in section 14 and 160 acres in sec-
tion 15, on the gentle east slope of Grizzly Hill.
The property was discovered by Lavasse in 1854 and is said to
have been worked steadily on a small scale. The Hydraulic King
Company worked it from 1907 to 1909, and the present company since
that date.
The deposit consists of a large amount of silt and sand and a small
amount of quartz on a slate and schist bedrock. The course of the
channel is southeast, the depth of the gravel being from 6' to 24'. It
is all said to carry gold.
Equipment consists of six houses, blacksmith shop, bams and a
sawmill of 8000 feet capacity. The water installation consists of two
giants working with 300'' under a head of 120'. There are 7000' of
24" pipe and two ditches, three miles and one and a half miles in
length.
The ground is worked by two giants, sluices 3' wide and 1500'
in length and 1000' of tail races. Eight acres have been worked.
Tailings are caught by a 20' concrete dam on Willow Creek.
There were 18 men (two shifts), employed at wages of from $2.25
to $3 per day and board, in 1914. Capacity is 1000 yards per day at
a cost of 15ff per yard. In 1912 the production was 7500 yards
valued at $4800.

The Alhambra mine embraces the Alhambra and Alhambra Exten-
sion locations. Patents have been applied for and final papers were
expected by January 1, 1914. The total area, which cover 3000'
along the lode, is 40 acres.
The mine is situated near the headwaters of the South Branch of
the Middle Fork Feather River on the southwest slope of Franklin
Hill. Deep caiions are characteristic of the surface.
It was located in 1855, but assessment work only has been done in
late years. The development work consists of an 85' vertical shaft
in diorite, and a tunnel driven on the vein, whose length is unknown
on account of caving. At the 60' level in the shaft a crosscut 12'
long through diorite shows the vein to be 14' wide and at the 80'
level another crosscut shows the vein to be 16' wide. There is one
small stope on the latter level, and an open cut on the vein 100' long
and 20' deep.
The strike of the Alhambra vein is east, and the dip vertical. The
south wall is diorite, the north wall 'porphyry' and the filling is
solid quartz, varying in width from 6' to 8', with gouge on both
walls. This quartz carries free gold, galena, pyrite, and chalcopyrite
in small amounts. On the 80' level three samples taken across 16'
of quartz assayed $9, but the ore is said to average only $5.

The mine contains one patented claim, the Altoona, extending 1500'
along the vein and 500' wide. It is situated on the flat top of the
ridge between Crescent Mills and North Canon, near the Round
Valley Reservoir, and is 16 acres in area.
The mine was discovered by F. Emmons in 1870 and was bought
by the present owners from the Emmons Estate in 1906. In 1912 it
was bonded to A. N. Fauntenack of Seattle, and 12 to 14 men were
employed, but during 1913 it was idle.
The greatest depth reached on the vein is by a winze, 100' below
the tunnel level, or 230' below the outcrop, and the length driven on
the vein is 800'. There is also a crosscut 170' to the south. A stope
30' X 5' X 150' extends from the adit level to the surface.
The wall rock is 'porphyry,' probably decomposed meta-rhyolite
or andesite, and the vein is a quartz-filled fissure and stringers, with
an easterly strike and a dip of 45° to 60° S. Its average width
is 5', the maximum 16', aijd the length of the pay shoot is 306', with
a width of 5'. The vein filling is iron-stained quartz containing free
£?old. In the upper workings the ore is oxidized, but at the bottom
of the winze sulphides are found in places. It is said to plate $5 to
$7 per ton in free gold. Both the country rock and vein are faulted.
Equipment consists of one Fairbanks-Morse 32-horsepower crude
oil engine, blacksmith shop, four new cabins and a Fairbanks 16-horse-
power distillate hoist. The mill building is equipped with a Denver
roller mill, patent electrical amalgamator, rock breaker and Card
concentrating table.

The property was worked in early days, but was bought by the
present owner in 1902.
There are three veins in the lode — the Poorman, 3000'; Antelope,
3000'; and Ilawkeye, 6000'. The Poorman vein has been developed
by a 140' tunnel with a winze from the tunnel 110' deep and a drift
20' in length along the vein on the tunnel level. The Antelope vein
is developed by a 65' shaft, and short drifts. A crosscut now being
driven will cut the vein 310' below the surface. The Hawkeye is
opened by a 70' shaft and a 200' tunnel driven on the vein.
Wall rock is ({uartzite in the Poorman and Antelope and a lime-
stone foot-wall and granodiorite hanging wall in the Hawkeye. The
Poorman lode is composed of stringers of quartz and country rock
containing free gold and no sulphides. The vein is 14' wide, with
2" stringers, and strikes north with a vertical dip. The Antelope vein
is 5' wide and is composed of silicious oxidized ore containing free
gold, malachite and azurite. It dips 30"^ E. with a northeast strike.
The Hawkeye contains lenticular })odies of chalcopyrite and native
copper in a zone 75' to 100' wide, striking northeast and dipping
50° E. The ore runs $14 to $21 in the Antelope, and $5 to $40 iii
copper, gold and silver in the Hawkeye. This mine is undoubtedly
on the southern extension of the Genesee-Wa.lker copper belt, which
seems to follow along the contact of the granodiorite wherever the
overlying basalt and andesite have been eroded.
Equipment consists of a cabin and blacksmith shop.

The property consists of six claims, all said to be patented. It
comprises 120 acres with a length along the lode of 5000'.
This mine has been worked at intervals for 16 years, but is idle
at present. Fifty thousand dollars is said to have been taken from
the shoot worked in early days in the Fissure vein (Queen of Genesee
jedge), from ore reported to have averaged $20 in gold and to have
carried a considerable amount of copper.
The old works, consisting of a 60' shaft and numerous tunnels,
100' to 300' in length, are caved, but some w^ork done by the Austrian
Syndicate is in good condition. The property can be developed to
a depth of 300' to 800' by tunnels from Robertson Ravine and to a
depth of 1400' by a proposed Cooper Mountain tunnel.
The country rock is meta-andesite and schists, in which there is a
(juartz fissure vein containing bornite and gold, 8' wide, with andesite
loot and hanging walls. It strikes northwest and dips 70° SW., and
basa length proven on the surface of 5000'. There is also an ore-
bearing zone in schists near their contact with porphyry. The ore
contains bornite and carbonates and has schist hanging and foot-
walls. An average width of about 2', with a maximum of 8', con-
tains 2% copper and $3.10 gold. The strike is northwest and dip

The property consists of three claims in the Bell group, Bell, Iowa
and Leavitt Extension, all of which are patented. The total area,
about 60 acres, covers a length of 2000' along the lode. It is situated
at the head of Elizabethtown Flat, where the ridge rises abruptly
from the flat.
The mine was discovered in early days by hydraulicking and in
1879 the present owners erected a 10-stamp mill on the property. It
is now idle. The ore is said to have averaged $15.
Development work consists of two tunnels, an upper tunnel 500'
long, and the lower tunnel 50' below, 600' long. There are numerous
crosscuts in the lower tunnel, and it has been stoped to the extent of
100' in length, 11' in width and 50' in height. On the north side of the
hill, a tunnel has been run on the vein a distance of 75', then a winze
sunk to a depth of 30' and a drift driven from the bottom, south, for
a distance of 30'. Old workings have caved.
The deposit is characterized by quartz veins and stringers in a
siliceous dike 60' wide, with both hanging and foot-walls of slate.
The vein is said to have been worked for a wddth of 11' to 15', the
ore being free milling, with a small amount of pyrite and manganese.

This property consists of four claims, the Mammoth, Whip-poor-
will, Jumbo and Jumbo Extension, located July 12, 1913. It con-
tains 80 acres, with 2580' along the lode, and is located on a high
7-idge of serpentine lying south of Haskins Valley.
Development work consists of shallow surface cuts across the lode,
which show the deposit to be auriferous for a width of 120'. The
property contains a decomposed body of iron-stained talc and ser-
pentine material, which strikes northeast. The gold-bearing zone
lies near the contact of the serpentine and the Calaveras slates, and
the ore is said to average $4 and $5 per ton for a width of 120'.

This property consists of four claims, all patented, having an area
of 76 acres. It is situated on the ridge on the north side of Genesee
Valley.
The mine was discovered in 1860. In the early days the ore was
smelted in the old Genesee smelter, or was shipped to Swansea, Wales.
No work has been done for a number of years.
There are several tunnels on the property. The main one is 500'
3n length with a number of drifts run on stringers. It developed a
5' vein of gold ore assaying $3.40. This vein, it is said, will cut the
copper vein within 100' at a depth of 240'. Some ore has been
stoped in the upper levels. The lower tunnel is in 270' in grano-
diorite. The upper tunnel, 60' long, exposes 14' of chalcopyrite, and
the middle tunnel, 120' long, shows 17' of ore averaging 6% copper.
The first working was from a shaft 65' deep, now inaccessible.
The country rock is slate, limestone and granodiorite. The ore
forms in solid masses of bornite and chalcopyrite, in limestone and
slates near the contact with granodiorite.
Near the surface there is malachite and azurite. It is said to carry
^•old and silver. The maximum width of the ore-bearing zone is

160 acres of timber in sections 14 and 15. It is situated on Indiaa
Creek on the west side of Indian Valley at the base of a ridge which
rises 1000' above the floor of the valley.
The deposit was diseovered in 1864 and worked at intervals until
1894, since which time it has bi'en idle. The surface workings are
tiaved and iuaccessibti" and the 400' shaft is full of water. It would
cost from $25,000 to .-fioO-OCO to reopen the mine.
The country rocks are meta-andesite. andesitc and slate. Appar-
ently there are a number of quartz veins and cross veins in the meta-
andesite and meta-rhyolite. They carry free gold and a very small

hanging walls 'porphyry' (meta-rhyolite). The Horseshoe vein has
a width of 17' of hard quartz and is 86' between the walls on the
400' level. It strikes N. 70° W. and dips 72^ S., with a proven
length of 400' on the surface. The Pet vein is 3' wide, strikes east,
and has a vertical dip. The Crescent vein varies from 5' to 8',
strikes northwest and dips 4.5° to 70° N, The ore stoped from the
('rescent ledge from the 200' level to the surface is said to have
_ averaged from +8 to iiil2 per ton for a width of 5' to 12'. On the
200' level at the junction of the Pet and Hor.seshoe veins, the ore
body was 15' wide and went from ^A to !|i5 per ton. On the 400' level
an orebody 17' wide and 60' in length is said to have averaged $5
per ton for the total width.
Development work consists of a 400' vertical shaft, and two cross-
cuts driven on the vein from the 400' level, 150' and 250' to the north

and south, respectively. In the crosscut to the south at a distance
of 117' a vein was encountered which is said to have had 17' of quartz
on the foot- wall and 76' of soft oxidized ' porphyry ' between the walls.
The body of quartz was 60' long and apexed 60' above the 400' level.
Ore was stoped from the Crescent ledge from the 200' level to the
surface.
The mine equipment is practically useless. The mill was torn
down and sold for junk in May, 1918.
Water for power was obtained from the Round Valley Reservoir,
but any power in the future will probably be electric from the Great
Western Power Company's Big Meadows project. Work begun
under the supervision of Albert Burch in the summer of 1918, was
discontinued because of war conditions.
The Green Mountain, the nearest mine, was last reopened in 1901.

This property comprises two patented claims, the Summit, 750' by
600', lying between the Indian Valley property and the Hibernia
claim of Standart, and the Crown Point, 600' by 1500'. It contains
30 acres and is situated on the top of the ridge south of Greenville.
The holdings were purchased in 1876 from the Bank of California,
but were not included in the sale of the Indian Valley mine.
The country rock is granodiorite and meta-rhyolite. The veins
are quartz-filled fissures containing free gold and sulphides, said to
run $16. It is now idle.
Development consists of a 600' tunnel driven on the Summit vein,
which is also cut at the 1200' level by the Union tunnnel from the
Indian Valley mine. The vein strikes N. 40° W., has a vertical dip
and a proven length of 1500' on the surface. Considerable ore has

are characteristic of the surface.
The deposit was located in 1911 and prospecting work was being
done.
A 40' shaft sunk on a vein is now inaccessible, and a crosscut tunnel
has been started which is in 20'. It will have to be driven 100' to
strike the vein 75' below^ the outcrop.
The veins are of quartz, occurring near the contact of serpentine
and Calaveras slates. The 40' shaft show^ed a vein 21" on the foot-

This property comprises the Diadem and Red Point patented quartz
claims and the Victor Fraction, 20( ?) acres in all, with a length along
the lode of 3000'. It is situated on the southeast slope of Spanish
Ridge, and steep ravines are characteristic of the surface.
The property was located in 1865. It is now idle and very little
work, development or otherwise, has been done in the last 10 years.
There are three tunnels, the lower tunnel 1000' long cutting the
\ein at a vertical depth of 300', the Arrastra tunnel 550' long, and
No. 2 tunnel 300' long, together with numerous crosscuts and a shaft
from the lower tunnel to the surface. Most of the ore taken from
this mine was from a shoot 125' long which was worked from the
Arrastra tunnel level to the surface, a distance of 250'. In early days
the surface was worked as a placer mine.
The lode is 60' in width, being a replacement of dolomite by silica,
quartz, chalcedony and in the lower levels large amounts of silicified
and altered dolomite. There is one vein, the Diadem, the filling
being quartz lenses, chalcedony, iron oxide, siliceous dolomite and
manganese, very rich in free gold 200' below the surface, with
ehalcopyrite and selenides. The foot-wall is slate, the hanging wall
schist. Its strike is N. 37° W., and the dip is 60^ NE., with a proven
length on the surface of 3000'. Owing to the altered condition of the
vein near the surface and the presence of oxides of manganese, there
has probably been a surface enrichment to a depth of 250', below
which point very little rich ore has been found. Pyrite concentrates
go $110 a ton and compose 1% to 2% of the ore.
Equipment consists of good buildings, shops, etc., and two old
Huntington mills. Steam and water power were used.
Adjoining mine is the Honeycourt.

This property comprises nine claims, namely, the Summit, West
Pacific, Bird, Pacific, Drury, Arctic, John Bull, Phoenix, and East
Phoenix, the latter seven being patented. There are 180 acres cover-
ing a distance along the lode of 4000', and 320 acres of timber land
included in the property. The surface is formed of high ridges and
steep canons.
The property was discovered in 1869. It was purchased by Droege
in 1905, and has been worked by Lindbloom since August, 1911. The
Droege mine includes the John Bull and Phoenix claims, on which a
considerable amount of work was done in early days. All work at
present (1918) is on the Drury or Ellis vein. There has been a total
production to date of about $300,000.
Development consists of two adits, No. 2 adit being 2400' in length,
and No. 3 adit 255' below No. 2, being 1900' in length. The latter
cuts the vein at a vertical depth of 600'. A winze sunk from No. 3
adit 1400' from the mouth, was put down 100' on the vein and drifts
driven west 150' and east 200', where • a fault was encountered.
The vein was again picked up by driving along the fault for a dis-
tance of 98', and the adit was continued on the vein beyond the fault
for 200'. Most of the ore above No. 3 adit level has been stoped to
the surface. In some places two veins have been stoped with a horse
of about 30' of country rock between. Short shoots have been and
are being stoped, both east and west of the winze on the 100' level.
The ore is run from stope chutes in small buckets, trammed 400' to
the shaft, hoisted by a small electric hoist to adit No. 3, and dumped
into bin; cars (1 ton) are hauled to the mill by horse, five cars to a
train. Very little ore is blocked out.
The deposit consists of lenticular fissure veins in country rock of
meta-rhyolite, granodiorite and serpentine. The Standart-McGill
vein is a crushed and oxidized quartz vein in ^porphyry' and green-
stone, probably a diorite, containing free gold and black oxide of
PLUMAS COUNTY. 115
manganese on the walls. In the unoxidized portion of the vein the
ore is said to carry from 2% to 59? of surphides. The foot- wall is
heavy decomposed and altered rock, possibly meta-rhyolite. The
hanging wall in some places is the same as the foot-wall and in other
is greenstone (diorite). The vein varies from a seam to 12' in width,
will probably average 4|', and strikes: east with a dip of 70° N.
There are numerous faults, some being post mineral.
The mine equipment consists of a 14" x 14" Rix compound com-
pressor driven by a Pelton waterwheel; three 3" machine drills, and
electric generator, 220 volts, 148 amperes, with direct connected
Pelton enclosed wheel. The mill contains 25 Hendy stamps, weight
1150 pounds, five Pindar concentrators (Buddie type), and amal-
gamating plates. It is in good condition.
Water is obtained from Round Valley Reservoir under a 300' head
at the mill and the same water is used again at the compressor plant,
300' below the mill. The number of men employed is 23 on top, 20 to
25 in the mine, and 4 (3 shifts) in the mill. Labor was paid $3.50;
mill men $4.50. The per cent extraction is 75%. Tailings run 40^
and are disposed of in North Caiion.
Adjoining mines are the New York and Indian Valley, both idle for
a number of years.
[Ten stamps were in operation in June, 1918. The ore is said to
average $5 with occasional rich shoots. Fifteeu men were employed.
Cost of mining and milling, which was $1.50 a ton in 1914, had
increased to $2.25 in 1918.]

as practically no work has been done since the XIII Report.
The property lies on the north side of the east branch of the North
Fork Feather River, and has been held for many years by the present
owner. The surface along the river was placered in early days.
The deposit consists of a quartz fissure vein in country rock of
slate, serpentine and limestone, carrying free gold and small amounts
of galena, pyrite and chalcopyrite. The foot and hanging walls are
slate, and the strike is N. 45° W., and the dip 55° SW. The lode is
shown to be 75' in width where the river cuts it, and there is a proven
length of 700' on the surface.

This property includes 12 claims, covering 240 acres and also a
water right. It has been held by the present owners for a number
of years, and developed by numerous tunnels aggregating 600' in
length. A vertical depth of 150' on the vein has been reached by the
lower tunnel and 150' has been driven on the vein. The contact can
be developed to a depth of 1200' by a lower tunnel. Assessment
work only is being done at present.
A mineralized zone 200' wide containing high grade kidneys forms
a contact deposit in country rock of granodiorite and limestone.
The ore carries bornite, chalcoeite, $20 in gold, and 158 ounces of
silver and is found in small bunches irregularly distributed. The

This property comprises the following claims: Thompson placer,
Schafer quartz, Last Chance and Scheiser Ravine. Application for
patent was made on the claims several years ago but the case was pro-
tested and afterward appealed by the Bureau of Forestry, but Little
has won in both cases, and expects patents in the near future. There
is a total area of 107 acres, 60 acres being placer. The length along
the lode is 3600'. High ridges and deep ravines are surface features.
The property was worked as a placer in 1850, but all the workings
do not cross the vein. It was first worked as a quartz mine by
F. Lewis in 1880. Rich Gulch, when placered in early days, is said
to have yielded $9,000,000, and the gold was undoubtedly derived, for
the most part, from the erosion of the Halstead, Elizabeth, Cameron
vein.
The deposit is a fissure vein in slate, with well-defined walls. There
is one quartz fissure vein composed of quartz and slate with gouge on
walls, containing free gold, small amounts of galena, chalcopyrite
PLUMAS COUNTY. 117
and arsenopyrite. It strikes N. 66° W. and dips 80° SW., with a
}>roven length on the surface of 3600'. The vein is supposed to be
faulted at the south end of the Scheiser claim.
Development work consists of three tunnels, the upper tunnel
(elevation 39200, 279' through slate; the middle tunnel (elevation
3750'), 530' through slate; and the lower tunnel (elevation 3620'),
150' through slate, but not yet to the vein. There are drifts, cross-
cutting the middle tunnel as follows : 94', 38' and 60', and a raise of
30'. The middle tunnel cuts the vein at a vertical depth of 150'.
There has been a total of 166' driven on the vein from the upper
tunnel and 391' from the middle tunnel. All the ground has been
stoped from the upper tunnel to the surface. The 391' of drifts,
from the middle tunnel, on the vein are all in ore varying from 1' to
5' in width, which is said to have an average value of $10 per ton.
There were two men employed in 1914.
The Halstead mine adjoins the Elizabeth on the southeast and the
veins are supposed to be the same, a fault having thrown the vein a
distance of 600' northeast at a point where Scheiser Ravine cuts
across the strike of the lode. The country to the northwest, which
comprises the Elizabeth mine, is badly broken and Scheiser Ravine
may be the result of the dislocation. This lode can be traced from
the East Branch North Fork Feather River, which it crossed near
Virgilia where the outcrop was extensively worked by hydraulicking,
through the Duncan, Halstead, Elizabeth Consolidated and Cameron
claims, a distance of twenty-five miles.
Fairplay Mine. Owner, F. E. Thomas, Quincy.

This property comprises two claims, the Fairplay and Fairplay
Extension, the latter being a fraction (500' x 600'). In all, there are
26 acres, having a length along the lode of 2000'.
This ground was located by the present owner in 1897, but assess-
ment work only has been done. The property is held in hopes that
the adjoining Bell mine will be worked.
Development consists of two tunnels, 90' and 50' in length, with a
winze from the lower tunnel sunk 25' which reaches the vein 70'
below the outcrop. Ore with an average width of 7' is said to
average $10 per ton.
This deposit is supposed to be a south extension of the Bell lode.
There is one quartz vein in slate, varying in thickness from 6' to 8',
striking N. 15° W. and dipping 80° E., with stringers from a few
inches up to 3' in width. It is free milling and contains some pyrite.

Brown Bear, Polar Bear, Grizzly Bear, and Cinnamon; the latter
being the only one unpatented. There are 204 acres in the tract, 184
patented, and a length along the lode of 8100'. Deep gulches with
steep slopes to the top of the ridge, affording fine tunnel sites, are
characteristic of the surface.
The property was discovered in 1876 by Geo. Brandt, and was later
purchased by the Five Bears Mining Company. At present it is idle.
The mill closed in December, 1912, but four men worked underground
until May, 1913. Gold production to date about $32,000.
The mine is developed by a tunnel, driven 1400' on the vein, its
lace being 900' below the outcrop. In the timnel between stations
909 and 1080 the vein is 9' wide and said to average 5^% copper,
from stations 1127 to 1240 the vein is 13' with chalcopyrite averaging
2.3%. At one point 350' from the mouth the vein is stoped 50' above
the tunnel level.
The deposit consists of orebodies irregularly distributed through a
zone of slates and shales of Calaveras formation, following a narrow
shear zone and forming imperfect veins. There are three veins but
only the main vein (zone) is developed. The filling is a small amount
of auriferous quartz, crushed slate and gouge. The oxidized ore
contains limonite, manganese oxide and free gold (rusty) ; the sul-
phide ore, chalcopyrite and chalcocite with a very small amount of
quartz. A zone of slate and shale 400' wide occurs with altered and
metamorphosed andesite on both foot and hanging walls, the andesite
sometimes being porphyritic. The strike is north, the dip varying
between 20° and 70°.
Equipment consists of two Pelton waterwheels, one 18" and the
other 48", a two-drill Giant air compressor, assay plant, blacksmith
shop, five houses, stable, air pipes in tunnel, a 10-stamp mill, 700-
pound stamps, feeders, and two Eccleston concentrators.
Water from Weed Creek, 200" under 109' head, is used for power,
but under 1200' head 500" can be developed.
Cost of development work about $7 per foot, mining 60^ per ton,
treatment 80^^, timber (own) 2^^ per foot, transportation 45^ per 100
pounds from Keddie. Extraction of gold about 60%.

This property comprises six claims, having an area of 120 acres and
a length along the lode of 1000'. The surface is characterized by
steep ridges and V-shaped caiions near the headwaters of several
creeks.
It was bonded to the present company in 1907.
The deposit occurs as quartz veins in country rock of Calaveras
slates and porphyrite. There are two veins, the Gold Leaf and the
Hobart, the former being a quartz fissure vein with small gouge on
both walls; both contain free gold and small amount of pyrite and
galena. The foot and hanging walls are porphyrite and schists. In
width the Gold Leaf vein varies from 2' to 14', the strike is north,
dip 70° W., and it has a proven length on the surface of 600'. The
Hobart vein varies from 3' to 20', with an average width of 4', strikes

The pay shoot is 200' long and averages 4' wide.
A crosscut tunnel has been run 200' to the Gold Leaf vein, on which
there is also a 35' shaft. Another crosscut tunnel has been run 650',
cutting the Hobart vein 125' below the outcrop, and there is an incline
shaft on the vein 100' in length. The Hobart vein has been stoped
from the surface to 25' above the main tunnel for a length of 50'.
The average value of the ore is $3 per ton, while that in the Gold
Leaf vein is said to assay $6 to $19.
Houses and a blacksmith shop comprise the mine equipment. The
reduction equipment consists of an old 5-stamp mill (850-lb. stamps)

This property consists of nine claims in all, three, the Jersey, Ever-
green, and Wolf Creek, being patented. There are 180 acres covering
a length along the lode of 3000'.
The property vsras purchased by G. Standart, father of the present
owners, in 1882. It was idle from 1911 to October, 1913, when it was
reopened with 10 men employed in cleaning out. The mine has pro-
duced to date about $750,000.
The deposit is a lenticular fissure vein near a contact of slate and
serpentine. The filling in both veins is quartz and slate, containing
free gold and very little sulphide. The foot-wall of the Gold Stripe
is serpentine, the hanging wall slate, but both the hanging and foot
wall of the Wolf Creek vein are schist. The veins are parallel, 500'
apart, and strike east, with a dip of 45° S., the lenses varying from
5' to 10' in width. The Gold Stripe has a proven length on the sur-
face of 4000' ; the Wolf Creek about 1000'.
Development work on the Gold Stripe vein consists of a 300'
crosscut adit which cuts the vein at a depth of 230', and 1000' driven
on the vein. The Wolf Creek vein is developed by a 600' tunnel
driven along the vein, 60' below the surface. In the Gold Stripe
three shoots were stoped, No. 1, 300' x 80' high; No. 2, 220' long
X 130' ; No. 3, 200' X 230' ; and in the Wolf Creek vein two shoots,
No. 1, 60' X 60', and No. 2, 100' x 60' have been stoped.

This property comprises seven claims, namely, the Quincy Nos. 1,
2, 3, Gold Rim, Gold Rim Extension, Spring Nos. 1 and 2 ; the Quincy
No. 1 is 1300' X 600^ all others 1500' x 600'. The total area is 138
acres, covering 4300' along the lode. Lava-covered ridges and deep
canons with steep grades to the Feather River mark the surface.
The ground was located by Hall in 1911, and assessment and
development work consists of two open cuts 13' x 17' x 10' deep, also
a 60' crosscut from Poorman's Creek, cutting the vein at a vertical
depth of 30'. Some good assays have been reported but it is not
known what the quartz will average.
The deposit consists of quartz veins and stringers in slate, but
development has not been sufficient to prove whether or not they are
associated with an igneous dike. One vein can be traced through
the Gold Rim, Gold Rim Extension and Quincy No. 1. Its filling is
iron-stained schist containing free gold and arsenical pyrite with a
foot and hanging wall of slate. The width varies from 6" to 24".
It strikes N. 55° W., dips 80"" E. and has a proven length on the

This property composes one claim, the Green Ledge, which is not
patented. It is situated on the east bank of Ward Creek with a steep
slope to the top of the ridge, and is 21 acres in area.
It was one of the first claims w^orked in the Genesee Valley district
and has been held by the present owners for over 20 years. From
one shoot 90' long, :V to 8' wide and 90' high it is said that $25,000
was taken, with an estimated loss in the tailings of $75,000 in
auriferous copper sulphides. Assessment work is being done in a
tunnel from the bank of Ward Creek 400' below the old workings.
Mine development consists of a tunnel 340' long, a shaft 138' deep
and a 24' crosscut at the bottom of the shaft. Eighteen feet of this
ucsscut averaged $2.80 gold and 1^% copper. The shaft is full of
water and the north adit has caved.
There are two veins, the Green Ledge and the Pocket, parallel
and distant from each other 240'. The country rock is slate, schist
and meta-andesite. The Green Ledge vein is a quartz and porphyry
fissure vein carrying free gold and copper sulphides. The foot-wall
is andesite and the hanging wall schist. It varies from 3' to 8' in
width, strikes N. 20° W., dips 80° NE., and has a proven length on
the surface of 5000'. The Pocket vein is a quartz vein with hanging
and foot- walls of schists, carrying chalcopyrite and chalcocite, which
contain high values in gold and silver. It varies from narrow
stringers to 4' in width, strikes N. 20° W. and dips 40° NE. Values
are found in pockets.
The only equipment is a blacksmith shop.

This property consists of three patented claims, the Ruby, Brilliant
and Emerald Fraction, and two locations, the North Star and Sarah
.Tane. The two latter were relocated in 1913 hy G. A. Hall and others
who claun that assessment work had not been done for a number of
years. The mill and entrance of tunnels No. "> and No. 6 are situated
"n the relocated claims. The t"tal area is 'lO acres, with a length
along the lode of 4500'. The outcrop is on the ridge whicli rises to
an elevation of lOCO' above Indian Valley,
The mine was discovered in 18(iO and worked at intervals until
1890 and is said to have produced to date $1,000,000 to $2,000,000.
The tunnel was last reopened in 1901 and all workings are now caved
Hnd inaccessible. It is estimated that $50,000 would be required to
leopen this property. Very little ore whs develojied on the No. 6
level, the orebodies having ap|i;irenti.v been lost by faulting between
No. 5 and No. 6 levels.

dips 45° to 50° SW., with a proven length on the surface of 3000'.
Ore from the Blake shoot was oxidized and free milling; that from
the Sulphide shoot was mostly auriferous pyrite.
There are six tunnels in all: No. 1 was 250' long; No. 2, 350' long;
No. 3, 1500' long; No. 4, 520' below the apex, 3000' long; No. 5 was
360' below No. 4 ; and No. 6, 480' below No. 5, was 6075' long. The
No. 6 tunnel was driven 1100' as a crosscut to the vein, then continued
for a distance of 1000' along the vein and then the hanging wall
west of the vein was crosscut for a distance of 4000'; the last 400'
being in serpentine. The end of this tunnel, when discontinued, was
about 600' east of the Cherokee shaft. The Blake shoot was stoped
200' above and 330' below No. 5 level and is said to have been cut off,
both above and below, by faults. This shoot was 300' long, 8' in
width and ran $10 to $12 per ton free milling. The sulphide shoot
was stoped from the 500' level to the surface, a distance of 920', and
is said to have been 8' to 40' in width.
There is no mine equipment at present. An old 60-stamp mill is
in ruins and worthless.
Water under 800' head was obtained from Round Valley Reservoir.

Indian Valley, Genesee, Honey Lake.
PLUMAS COUNTY. 125
This property includes three claims, the Genesee or Grass, and
Genesee Extension, lode claims, and the Lebanon placer claim. It
has an area of 60 acres with a length along the lode of 2700'. The
vein occurs at the base of the ridge where Ward Creek enters Genesee
Valley Flat.
The mine was discovered in 1856 by Ward and Davis. It was
I^urchased by Gruss in 1881 and since that time has been worked by
the Gruss family, being credited with a total production of $460,000,
of which amount $185,000 went to Gruss.
The mine is developed by a 100' vertical shaft from which there are
drifts 500' north and 300' south. The new 200' vertical shaft is
connected by an incline raise on the vein of 183'. Prom the 200'
level a crosscut runs 96' east from the shaft to the lode, then 150' is
driven south but not on the vein, and from this two crosscuts are
driven at 80' and 150', west 25' and 70', respectively, to the vein;
and 30' is driven on the vein south from the latter crosscut. The
ground has been stoped from the 100' level to the surface, a length of
800' and an average width of 5'. A cross vein in what is known as
north hill has also been stoped for 150'. Ore was being broken in
1913, 50' below the 100' level, but very little ore has been stoped from
the 300' to the 100' level. Ore then being broken near the top of the
raise is drawn off at the 200' level, trammed 300' to the shaft, hoisted
to the surface by a water-driven hoist, crushed in a Gates crusher in
the head frame and fed directly into a 10-stamp Hendy mill. Tail-
ings are dumped on the placer claim.
The character of the deposit is crushed and brecciated shear zones
in slates and schists near the contact of the slates and meta-andesite.
There are no well-defined veins, but parallel stringers of quartz and
calcite occur. The decomposed and altered rocks are iron-stained
and the gold occurs in narrow seams and pockets containing limonite
and manganese oxide. The foot-wall is altered schist and, in some
places, slate, the hanging wall is black slate, altered and iron-stained
near the vein. There are two parallel zones 20' to 30' apart, with an
average width of 5' and a maximum of 20' each, striking N. 20° W.
and dipping 45' to 60' W., with a proven length of 800' on, the
surface. Most of the gold occurs in the oxidized veinlets in the shear
zones, oxidized to a depth of 200'. On the 200' level sulphide ore-
bodies have been encountered, containing bornite, tetrahedrite and
ehalcopyrite following calcite seams in the altered schists. The gold
in the oxidized zone is generally fine and * rusty' and difficulty has
been experienced in the past in amalgamating. One per cent con-
centrate ranges from $150 to $350 per ton in value.

The property consists of four claims, including the Rich Gulch,
Byers and Halstead. There are 80 acres, with a length along the
lode of 6000'. The surface is characterized by steep ridges, giving
excellent opportunities for development by tunnels.
It was discovered in 1881 by Joe Halstead. Most of the develop-
ment has been in the form of assessment work, and consists of two
tunnels, the English, 200' long and cutting the vein 150' below the
outcrop ; and the Blacksmith tunnel, 350' in length with two crosscuts
in it. At present the mine is idle.
The country rock is slate and serpentine. The deposit is quartz
fissure veins following the general strike of the slates, associated with
veins in a brecciated mass of altered and silicified rock which has
been recemented by quartz carrying gold, galena, pyrite and small
amounts of chalcopyrite. The walls are slate. Quartz veins are 3'
and 4' in width, but the altered and silicified breccia* is 20' to 30'.
The strike is N. 43° to 53° W., the dip 65° to 75° NE., and it can be
traced at intervals for 6000'. There is a 200' pay shoot in the English
tunnel. The ore is free milling and is said to average $3 to $4.50,
but probably not for the whole width of the vein.

sion, Plumas, Kesmett and Seiieea Eureka. The total area of 200
acres is characterized by a steep ridge running east. The ridge is
very narrow, showing quartz on the surface, and the vein probably
follows the course of the ridge.
The original locators were Rickard and Mandeville. The property,
then consisting of three claims, was purchased in 1893 by Hazzard.
There is one man working.
It is developed by two tunnels, the Ridge tunnel of 580' and the
Bear tunnel of 230', and two crosscut tunnels on the Bear vein, below
Bear tunnel, of 95' and 300'. Neither of the two latter have encoun-
tered the vein, which is supposed to lie very flat.
The deposit is apparently a dike of fine grained rock brecciated
and reeemented by quartz carrying auriferous sulphides, pyrite and
arsenopyrite. There is one main vein of quartz and dike rock, which
has been folded into an anticline, the filling being quartz and
cemented breccia with streaks of solid sulphides. Free gold occurs
in the oxidized portions, but very little is found in the sulphide zone,
which is near the surface. The foot-wall is composed of slate, the
hanging wall of slate and schist. The width of vein is from 5' to 20'
and strike east. It dips 40° S., the Bear vein on the other leg of the
anticline, dipping 45° N. Values are very unevenly distributed in
the sulphide ore, assays from the same sample varying by a wide
margin. Partially oxidized arsenical ore assays from $6 to $25.

The Dewey, Hobson and Black Jack claims comprise this property.
With an area of 60 acres, it covers a length along the lode of 4500'.
The vein follows the course of a steep gulch from Soda Creek to the
top of the ridge with a difference in elevation of 1000'.
The mine was worked by J. S. Hall in 1875 and was then known as
the Plumas National. Relocated by the present owners in 1903, it is
now under bond to G. H. Hall, son of the former owner. When the
sulphide orebody in the lower tunnel was encountered, a roaster was
erected, and attempts were made to treat the ore in this manner, but
only $12 of the $32, which the ore is said to have averaged, was
recovered. The shoot was 600' in length and 6' in width.
Development work consists of an upper and lower tunnel. The
upper tunnel «uts a 6' vein 400' from the portal at a vertical depth of
400'. The lower tunnel, at a distance in of 1540', cuts the vein at a
depth of 1000'. There is no connection between the tunnels.
The deposit is a quartz vein in slate, the country rock being slate
and meta-andesite. There is one vein consisting of quartz, black
talc gouge and black slate, containing free gold with some sulphides.
The foot-wall is meta-andesite (altered) and the hanging wall is black
slate (altered). The vein varies from 6' to 8' between vralls, but it is
not all solid quartz. The strike is N. 40° W., the dip 45° S., and there
is a proven length on the surface of 4500'.
The Plumas Amalgamated adjoins this property, and Hall has a
theory that the Plumas Amalgamated vein is a faulted portion of
this vein.

This groitp comprises thirty-one locations, on nearly all of which
some development has been done. They are the Moonlight, Wasp,
Grant, Hulsman, Sherman, Oregon, Olympia, Davenport, Edward,
Sidehill, Sperm, Oak, Shough, Gentle Annie, Cabin Ridge, No
Wonder, Dexter, Live Oak, Fair View, Stone Point, Fritz, Big
Spring, Big Boo, Belmont, Claremont, Vermont, Pala Cedar, Orient,
Mammoth and Crystal. The mountain side on which they lie is
very abrupt.
A tunnel has been started well down, so as to obtain 800' to 1000'
of depth under the heaviest croppings. This is a crosscut tunnel
and is in 150'. On the Mammoth claim several open cuts show sul-
phide and carbonate ore, which can be traced northerly for 900'.
On the Orient claim a tunnel has been driven 150'.
The Gentle Annie claim is prospected with open cuts. On the
Oregon there is a 13' shaft at the east end, and on the west end a
superficial cut. Down the hillside from an outcrop on the Olympia
claim is an 85' tunnel. There is a 20' open cut along the outcrop of
the vein on the No Wonder claim. On the south hillside is the
Palisades tunnel, which was driven to cut a ledge which crops 12'
in width above it. This tunnel has a length of 197', but has not
reached the ledge aimed at, although it has cut several small veins.
The country rock is granodiorite and meta-andesite, the veins being
quartz veins carrying gold and silver and copper sulphides. On the
mountainside and following the course of a proposed tunnel are
12 ledges. The widest vein is found near the apex of the hill and
is about 13' wide. The character of the ore is carbonate with some
sulphide. On the Gentle Annie claim there is a vein varying from 6'
to 8' in width. The ore is siliceous, carrying red oxide, carbonates
and pyrites, and can be traced for over 800'. A 13' shaft on two of
the claims shows peacock copper ore in the bottom. Their width is
unknown. Assays are reported as showing from 10% to 60% copper.
The shaft on the Oregon claim is in green and blue stained ore, said
to contain 20% of copper and to be rich in gold. Some copper
glance is visible in the ore. The vein strikes south of west and the
north wall is diabase, the south diorite. On the west end of the
Oregon claim, a cut discloses some good carbonate and siliceous ore
reported to assay 48% copper, $14 gold and 15 ounces silver. A
vein parallel with the main one just described also shows good ore.
On the Olympia claim a vein of carbonate ore outcrops and is exposed
SO' in width by an open cut. The tunnel lower down the hillside
cuts 30' of gray carbonate ore. The inclosing rock is a diabase,
spotted with coarse crystals of feldspar. A vein of green carbonate

This property comprises four claims, Independence No. 1, No. 2,
Emancipation and Gem. There is a total of 80 acres, covering 3000'
along the lode. Lava-covered ridges and steep ravines are charac-
teristic of the surface. Winters Creek flows north from Mt. Wash-
ington, where the lava-capped 'Old Channel' is located.
The property was located in 1911, and eight men were working
until November, 1912. One hundred twenty tons of ore said to
average $186 per ton were shipped to the Selby smelter.
Development work consists of two inclined shafts, 50' apart, 30'
and 55' deep. There is a 30' drift connecting the two shafts 25'
below the surface, and two crosscuts 10' below the surface on the
Emancipation-Gem vein.
There are two veins, the Emancipation-Gem being 200' west of the
Independence. Both are quartz veins associated with 'porphyry'
dikes near the contact of serpentine, slate and schist. The Inde-
pendence vein is composed of quartz and altered porphyry containing
free gold and arsenopyrite in various stages of oxidation. The foot-
wall is 'diabase schist,' possibly amphibolite, and the hanging wall
slate: It varies from 3' to 10' in width, strikes N. 45° W., dips
55° W. and has a proven length on the surface of 500'. The
Emancipation-Gem vein is composed of quartz and altered porphyry
containing free gold and pyrite. The character of the walls has not
been determined. There is a zone 150' wide, 6' to 20' of which is
claimed to be mineralized, which strikes N. 26° W., dips 55° E. and
has a proven length on the surface of 3000'. These are supposed to
be the southern extension of the veins worked in the Plumas Bonanza
mine.

This property comprises in all 580.9 acres, two patented placer
claims, 235 acres, one placer location, 160 acres, and nine quartz
claims, all patented, 185 acres. Steep slopes are characteristic of the
surface, but the veins are near the creek level and can not be
developed by tunnels.
The property was discovered in 1888 and bought by the present
owners in 1889. From 47 to 50 men are usually working. Shut
down in September, 1913, for lack of water, but reopened in January,
1914. No dividends have been paid for the past three years, all
money taken out being put in exploratory work which has so far
developed little ore, and unless other orebodies are developed the
mine will probably be shut down for good within a couple of years.
It averaged a monthly production of 1900 tons worth $5500 to $7000.
Bullion production to November 1, 1913, was $1,358,925, concentrates
34,511 tons at $5. Fifty men working in July, 1915, with good ore
coming from new workings.
Development consists of the Haskins drain tunnel, 1800' long,
driven S. 20° E., which strikes the shaft at the 165' level, then a
( rosscut driven southwest 1150' from the bottom of the shaft, where
the new vein was encountered by a raise of 170' from the crosscut.
A drift was driven south on this vein for 1400' and the vein was
btoped 50' above this level, where it was cut off by a fault. The
main crosscut was then driven west 200' at an angle from its former
course, and another raise of 100' was put up to the vein and a drift
driven south about 1500'. No. 2 level: The ground has been stoped
between this and No. 3 level, above. The crosscut was continued 100'
and another raise was put up to the vein 50' above the crosscut and a
drift was run south on the vein for 1160'. Most of the ore was stoped
between this level and No. 2 level above. The crosscut was continued
beyond the raise for a distance of 120', where it intersected the vein
on its dip. From No. 3 drift a crosscut was run west and at a
distance of 190' intersected a vein dipping 70° W. and some

specimen ore was taken out. The hanging wall of this vein is a line-
grained porphyry dike. The crosscut was continued through this
porphyry dike, driven 450' in gabbro, and from the end a 490' raise
at 45° was put up. The shaft is 325' deep.
The deposit consists of fissure veins in gabbro. There are two, the
old vein and new vein. The former is quartz containing free milling
oxidized ore, and 600' of pay shoot has been worked. It averages
10' in width and has no outcrop, having been discovered in placering.
It strikes N. 20° W., and dips 25° E. The new vein is quartz carry-
ing free milling gold and auriferous pyrite which contains a small
amount of gold ($13). This vein averages 10' in width and has no
outcrop, having been encountered in crosscutting. It strikes N. 15°
W. and dips 30° W. There are four pay shoots, worked for 800'.

This property comprises two patented claims, the Morning Star and
Trenton. There is a total area of 40 acres with a length along the
lode of 3000'. Frazier Creek divides the property, cutting across the
strike of the vein. There is an easy slope from the creek to the top
of the ridges.
The claims were located in 1876 by O'Brien and Sullivan. In 1890
the property was purchased by Robinson, bonded in 1905 by Trow-
bridge and in 1912 by Holbrooke and Cohn, San Francisco, who, it
was reported, spent $10,000 and only succeeded in sinking the shaft
10' before work was abandoned. Chas. Lyser was superintendent.
It has been idle since the summer of 1912.
Development work consists of a shaft 100' deep near the portal of
the lower tunnel on the east side of Frazier Creek and a drift on the
vein 150' to the northeast from the bottom of the shaft. There are
also three tunnels on the vein — the upper tunnel, 75'; middle tunnel,
300'; and lower tunnel, 300', northeast of the creek and 300' south-
west of the creek. All groimd is stoped from the lower tunnel to the
surface, and a small amount from the 100' level in the shaft.
The deposit consists of a fissure vein near the contact between
granite and diorite. The vein filling is quartz and in some cases
decomposed granite and glass quartz crystals. The vein varies from
2' to 4' in width, strikes N 41° E., and dips 80° E. The foot-wall is
granite, the hanging wall diorite, and there is a proven length on the
surface of 2000'. Several pay shoots 40' to 50' in length developed in
the 600' opening. The ore is said to average $10 per ton, 2% sul-

PLUMAS COUNTY. 145
This property embraces seven and a fraction claims, namely, the
Baltimore, Little Joe, Mother Lode, Evening^ Star, Fine Friend, Key-
stone, Gold Fish, and Home Rule. There are 150 acres covering a
length along the lode of 4500'. It is situated in the caiion and on the
ridges on both sides of Ward Creek.
The property was discovered in 1902 by the present owner, who
has been working it alone.
A copper-bearing zone has been developed by numerous shallow
shafts and superficial open cuts. There are two shafts on the Little
Joe claim, 80' and 24' deep, and a shaft on the Gold Fish 30' deep.
A tunnel has been started on a narrow stringer called the Keystone
vein which is said to be an extension of the Gold Fish vein. On the
Mother Lode claim a tunnel has been driven 110' through the
andesite porphyry, 250' south of the Little Joe shaft. This will have
to be driven 50' further.
The deposit is composed of stringers and bunches of quartz and
altered schist, the quartz carrjdng sulphides of copper and free gold
in the oxidized portion of the different zones. The foot-wall and
hanging walls are schist and andesite. There are a number of
parallel shear zones, all of which show more or less indications of
copper. The general strike is N. 30° to 40° W. All dip about 45°
E. except the Gold Fish, which dips 45° W., nearly the dip of the
slates which lie to the west of the Gold Fish claim. A lot of 13 tons
of ore is said to have been shipped to Selby's which averaged $86 per
ton (gold $6.36, silver 43 ounces, and the rest copper). This ore
was taken from the Little Joe shaft and was hand sorted, ratio
unknown. A lot of 300 tons on the dump is said to average $30
per ton.
Water power could be developed if necessary.
Adjoining mines are the Five Bears and the Gruss.

The mine was discovered by the present owners in 1895. The
Wheeler Lumber Company tried to patent the ground but the patent
was protested by Kutchendorf . The two owners worked the property
in 1913.
It is developed by a main tunnel driven at an angle from the foot-
wall to the dike, across the dike to the hanging wall vein and a
drift run 300' east on the vein. A winze is put down from the point
where the tunnel cuts the ledge 45' on the vein, also a winze 275'
from the crosscut is sunk 20' on the vein. Another tunnel started on
the east end of the claim in the dike, if run 400' more will cut the
vein 100' below the upper workings.
The deposit is a dike of ' porphyry ' 70' in width with quartz veins
on each wall. The dike is decomposed and full of small quartz
stringers. The country is badly faulted. There are two veins, the
hanging wall and the foot- wall vein. The former is characterized by
quartz, with gouge on both walls, containing free gold and pyrite,
partially oxidized. The foot-wall is the porphyry dike and the
hanging wall slate. The vein varies from 4' to 11', strikes S. 87^ W.,
dips 60° to 70° S., and has a proven length on the surface of 1500'.
The ore assays $2 to $7 per ton. The foot-wall vein is made up of
quartz and clay carrying free gold and no sulphides. Its foot-wall is

The Mountain Lion Nos. 1, 2, 3 and 4 claims comprise this property.
There is a total of 80 acres with a length along the lode of 6000'. It
is situated on the steep slope from Ward Creek to Peele Ridge (4000'
to 6000').
The property was discovered in 1902 and acquired by the present
owners in 1905. It is idle at present, assessment work only being
done.
It has been opened on the surface by numerous trenches. A cross-
cut tunnel 750' in length will have to be driven 50' farther to cut
the vein.
There is one vein, the Mountain Lion, from which white quartz
came from some of the surface cuts carrying bornite, 'gray copper'
(tetrahedrite), free gold $400, silver as high as 20 ounces and 6%
copper. Both walls are meta-andesite. The vein varies from 5' to 6'
in width, strikes N. 20° W., dips 75° SW., and has a proven length on
the surface of 1100'.
Adjoining mines are the Gruss and Five Bears.

This property is composed of four locations, namely, the Plumas,
Oliver Quick, Mudhen and Minnie S. The Mudhen is a north exten-
sion of the Minnie S., which is a north extension of the Morning Star.
There are 80 acres covering a length along the outcrop of 3000'.
The property was located in the early days by J. Peppin. Assess-
ment work only was being done in 1914.
The Minnie S. vein has been developed by shallow shafts and open
cuts. A crosscut tunnel has been driven 700' through granite in
doing the assessment work for the past 12 years and it is believed
that the vein will be cut 160' below the outcrop, within a few feet.

Shallow shafts and open cuts comprise all that has been done on the
vein covered by the Plumas claim.
The Minnie S. vein strikes N. 37° E. and dips 80° E. Ore from this
vein resembles the Morning Star ore and contains free gold, galena
and ehalcopyrite in small amounts. The ore from the surface is
reported to have run a? high as $90 per ton. The foot-wall is granite,
the hanging wall diorite, and the vein is said to be 3' wide.

This property contains five claims, known as the Native Son No. 1
to No. 5. It is situated on a high ridge south of Genesee Valley, and
east of Ward Creek.
The holdings were discovered in 1907 and purchased by the present
owners in 1910.
The mine has been developed by a 200' tunnel, a 45' shaft and open
cuts, but assessment work only is now being done.
There is one vein, a quartz stringer vein carrying ehalcopyrite, in
a siliceous zone near the contact of slates and altered andesite. The
foot-wall is slate and the hanging wall slate and andesite. The
siliceous zone is said to be 100' in width. It strikes N. 30° W., dips
70° SW., and has a length proven at intervals on the surface of
4000'. It is said to be a continuation northward of the Walker
Brothers deposit, but this is doubtful.

This property comprises 23 acres with a length along the New
Century vein of 1500' and along the Whidden of 1200'. Not patented.
The New Century location lies southwest of the Caldwell claim, and
the Whidden Fraction location, 1200' x 100', lies northwest of the
Caldwell, between it and the Jennie mine. Low ridges are charac-
teristic of the surface.
J. A. Hall is doing assessment work on the claims.
The Whidden vein is developed by a 40' tunnel. The New Century
has three adits, the upper adit 160' long, 25' below the outcrop, the
FLUMAS COUNTY. 149
middle adit 190' long, 60' below the upper tunnel, and the lower adit
280' long, 90' below the middle tunnel. There is a raise from the
middle to the upper tunnel, in which is said to be 60' of ore averaging
$12 per ton, the limits being $8 to $40. Ore from the Whidden vein is
said to mill $14. Concentrate to the amount of 2% assays $100
per ton.
The deposit consists of two small quartz fissure veins in granite.
The New Century vein is free milling and contains 2% sulphides. It
averages 18" in width, strikes N. 35° E., dips 70° B., and has a proven
length on the surface of 5000'. The Whidden vein contains 2%
sulphides and is free milling. It averages 16" in width, strikes north-

This property embraces the following claims: New York placer,
40 acres (patented), Buena Vista, Prospect, Plowboy (patented),
New York (patented), Brooklyn, Luson placer, and 80 acres of
timber. There is a total of 230 acres covering a length along the
lode of 6000'. It is situated on the steep slopes from the canon to
the top of the ridge, giving good tunnel sites.
This mine was operated from 1872 to 1883 by Troleaven and May.
It was reopened in 1898-1902 by J. D. "Whitney, but assessment work
only, has been done in the last few years. The mine is said to have
produced to date about $400,000. During the Whitney regime 12,000
tons of an assay value of $70,000 yielded $43,000 bullion.
The property is developed by three tunnels. No. 2 tunnel, 1800'
in length, is 90' below the outcrop. It is driven as a crosscut for
297' and then on the vein for 1350'. No. 3 tunnel, 190' below No. 2,
has been driven 450' as a crosscut and will have to be driven 300'
farther, to cut the first pay shoot. From 1872 to 1883, 600' along the
vein from No. 2 tunnel to the surface was stoped. Under the
Whitney management it was extended 700'. Stopes in that distance
yielded 12,000 tons for a distance of 100' above No. 2 level, the
average length of the shoots being 90' and width 12'. From No. 2 to
the surface it is estimated that the ore resources are 75,000 tons, net
value $261,000 (ore value per ton $7, working costs and metallurgical
losses $3.50, net value per ton $3.50). It is also estimated that if

No. 2 tunnel is continued ahead for 800' and the lower tunnel is
driven 1500' on the vein with the same results as in No. 2 tunnel,
400,000 tons of additional ore will be blocked out.
The deposit consists of the main New York vein, and two smaller
veins, which have not been prospected. It is a quartz-filled fissure,
the orebodies occurring as lenses in quartz and porphyry vein filling.
Some of the ore is a recemeiited fault breccia. The ore is free milling,
(•xidized near the surface, pyritic below. Both walls are quartz
porphyry. The deposits are lenticular shoots 150' to 250' in length,
40' to 50' apart and 8' to 18' in width. The strike is N. 21° W., dip
63° SW., and it has a proven length on the surface of 6000'. Seven
pay shoots averaged 90' in length and 12' in width. Minor faults
are common.
Equipment consists of blacksmith shop and tools, small hoist,
sinking pumps, Giant air compressor (320 cubic feet free air per
minute), belt driven from Pelton waterwheel, air drill, cars, houses,
stable, messhouse, assay office, and an old 15-stamp mill built in 1871.
Water from Round Valley Reservoir under a head of 320', but with
an 800' head possible, is available. The ditch carries 600" and water
costs 10^ per inch.
Costs for mining $1.30 per ton, treatment $1.83 per ton (old mill).
Loss in treatment per ton 52%, extraction 48%. Tailings $3.20 to $4.
Total operating cost per ton $3. Concentrates 3% run $50. Labor
cost $3.50 per day. Transportation charges San Francisco to mine
1^ per pound. Good ore was encountered in the upper workings in
November, 1915, and driving on No. 3 tunnel was to be immediately
resumed. The operators planned to build a 10-stamp mill in the
spring.

There are eight locations, covering discoveries by Hewitt Brown
in 1907 and 1910 in this property, a total of 160 acres with a length
along the lode of 7500'. It is situated in deep V-shaped canons, one
mile east of Pilot Peak, a lava-capped elevation 7500' high.
An adit, 500' long, cuts the vein 100' below its outcrop, and there
are two 10' crosscuts to the west wall 450' and 500' from the mouth
of adit, also one crosscut to the east in slate for 50' and a raise of
100' to the surface. One stope 50^ north of the raise ext^ids 60'
above the tunnel level. This length may be the limit of the pay
shoot ; the owners, however, claim that there are no well-defined zones
of enrichment. All drilling is done by hand, and very little blasting
is necessary as the material can, in most cases, be worked by pick

and shovel. Ore is loaded in the tunnel from chutes, trammed to the
adit mouth and lowered by ears to the mill 200' below. Tailings are
disposed of in Hopkins Creek.
The orebody consists of stringers of quartz in a decomposed dike,
which is so altered in the present surface workings that it is impos-
sible to determine its original character. There are two parallel
veins 300' apart, of the same character, replacement and impregnation
of dike by quartz, only one of which is developed. The ore is for the
most part oxidized but some small bunches of partially oxidized
{irsenopyrite have been found. The walls are Calaveras slates, and
the decomposed dike material ranges from 10' to 15' in width. It
strikes N. 13° W. Near the surface the vein dips 80° W. ; where cut
by the tunnel 100' down it is nearly vertical, and it will probably dip
east at depth. There is a proven length of 3000' on the surface. The
ore is said to average $10 with assays as high as $100 probably from
quartz stringers. As all of the workings are in the oxidized zone,
it is impossible at present to tell the size and value of the orebody in
the unaltered zone, but at depth the quartz veins will carry a large
percentage of arsenopyrite. It is doubtful whether the unaltered
dike rock will carry values throughout its entire width. The arseno-
pyrite concentrates vary from $15 to $25 per ton in value.
Water is used for power. Equipment consists of a blacksmith
shop, good house and barn, and a 5-stamp mill (1059 pound stamps)
with two Johnson concentrators. Transportation charges are 1^ per
pound from Quincy.
The Rose quartz is the nearest mine.

There are two claims composing this property, the Oversight and
the Oversight Extension, 40 acres in area and covering the lode for
3000'. Steep V-shaped canons are distinctive features of the surface.
The claims were located by the present owners in 1911. One man
was working in 1914.
The mine is opened by two tunnels, No. 1, 70' long, driven on the
Big vein, and No. 2, 130' long, driven on the Stringer vein. Two
winzes, 15' and 10' and two raises 10' and 25' from No. 2 tunnel, fol-
low rich bunches of partially oxidized ore.
The Big vein is a quartz vein in decomposed serpentine. The foot-
wall is altered serpentine, the hanging wall schist. The ore is quartz
with mariposite, and bright green chromiferous mica, probably

resulting from alteration of serpentine. It averages 6' in width,
strikes north and dips 65° W. The gold is evenly distributed and
the vein has a proven length on the surface of 200'. It is said to
average $4.99 to $6 per ton. The Stringer vein is a 6" quartz
stringer at right angles to the cleavage of the slates, containing
arsenopyrite. Both walls are schist and slate. It strikes N. 3° W.,
dips 40° W., and contains rich pockets of oxidized ore. There is a
fair prospect of developing good ore in the Big vein. The Stringer
vein does not amount to a great deal but may enrich the Big vein at
the point of intersection, approximately 100' below the present adit
level. On the surface the Stringer vein lies about 200' east of the Big
vein.
Adjoining mines are the Crescent Hill Gold Mining Company, one
mile north across Feather River Canon, and Plumas Bonanza, one
mile east across the ridge in Winters Creek basin.
Recent crushing (in 1916) showed an average of $15 per ton with
some ore of higher grade.

This mine is situated on the eastern border of the north arm ot
Indian Valley at the foot of Indian Range.
It has been worked intermittently as a gold mine ever since 1867,
but the old mine openings have long since caved. Development
during later years consists of two tunnels crosscutting the ledge, with
various drifts, upraises and winzes totaling 1700' in length.
The ledge runs from 5' to 15' in width, and has a well-defined
hanging wall formed by a fault plane. It strikes N. 33° W., with a
dip of 50° SW. The formation is chiefly felsite, and felsitic
porphyry, occasionally becoming schistose; overlain to the east by a
red metamorphic schist, probably of igneous origin. The ledge is
evidently an impregnation deposit, with the strongest mineralization
next to the hanging wall. Above the water level its original sul-
phides of iron and copper are largely oxidized and the copper leached
out, while the manganese silicate which abounds has originated
various oxides, chiefly pyrolusite. Gold forms the principal value
above the water level, with from 2% to 3% of copper, as bornite,
copper glance and some carbonates of copper. The gold alone has
so far been the object of development.

This property contains six claims, a total of 120 acres covering a
length along the lode of 3000'. Lava-capped peaks and deep
V-shaped canons mark the surface.
It has been owned by Turner since 1900. Three men were working
in 1914.
A crosscut tunnel 500' in length was being driven which will
intersect a vein and give 100' of backs.
There are two veins on the property, one of which is developed.
Slate, capped by lava, forms the country rock. The developed vein
is a quartz-filled fissure with a large percentage of arsenopyrite and
some free gold. It lies between a foot-wall of black slate, and a
hanging wall of schist or slate. The vein varies from 4' to 6' in
width, strikes northwest and dips east. Ore from this vein is said
to average $15 for the whole width. It is mined by hand drilling.

This company holds nineteen claims, maps and names of which are
not available. There are 380 acres in all, situated on the top of a
flat ridge with a rapid fall to Soda Creek.
The property was discovered in 1880 and was purchased in 1910 by
the present owners. About 20 acres of the 'blanket' vein was stoped
by former owners. Six men were working in 1917.
All of the development work has been done under the blanket vein
by a tunnel 275' below the top of the hill. This tunnel appears to be
lower than any portion of the blanket vein and all of the ore has been
developed by raises from different branch drifts. The main tunnel

was driven a distance of 500' S. 10° W., at which point a drift was
run 400' to the west. It was then continued 100' S. 10° W., and a
drift was run 100' in an easterly direction. It turned and was
driven nearly west for a distance of 200' and then in a southwesterly
direction for 700', making? a total length of tunnel of about 1500'.
From points 200' and 500' beyond the turn, drifts were run west for
100' and 115', respectively. The work so far accomplished by the
present owners has been in the nature of exploratory work only and
no estimate of the ore reserves can be made.
The deposit is characterized by quartz veins and stringers near the
contact of slates and meta-andesite. The Monitor blanket vein lies
nearly flat on the top of the hill and covers an area of about 60 acres.
All of the ore is oxidized and free milling. The foot-wall is quartzite
?nd greenstone, the hanging wall clay slates. It lies as a sort of
synclinal fold, and dips both north and south with a maximum of
20^^. The width of the stringers and slate varies 8' to 20' with the
pay ore occurring in bunches. The Black Prince vein is a free milling
quartz vein in greenstone. The foot-wall is greenstone (altered
andesite), the hanging wall quartzite and greenstone. The vein is
solid quartz 8' wide, striking N. 10° \V., and dipping 15° SW., with
a proven length on the surface of 400'.
The geology of this property is complex and a detailed study of
the deposit would have to be made to arrive at any definite con-
clusion regarding the origin and possibilities of the Plumas Amal-
gamated deposit.
The mine is equipped with a superintendent's house, bunkhouse
and blacksmith shop.
The mine was equipped in 1914 with ten 225-pound Straub stamps,
operated by steam and having a capacity of 12 tons in 24 hours.
Amalgamation only is used and recovery is said to be about 70%.
The property was idle in 1918.

The mioe at that time was developed by a 50' shaft and 60' driven
on the vein from the bottom of the shaft. No ore had been stoped,
the mill being run on rock taken out in development work.
The deposit consists of quartz veins cutting across the strike of
states, probably following a siliceous dike. There are two veins, but
practically no work has been done on the Creek vein. The vein
filling is quartz, gouge and kaolin, the solid quartz outcrop showing
15' wide in places. The quartz is free milling, with very little
sulphide as the workings are in an oxidized zone. It varies from
6' to 20' in width, averaging 8', strikes N. 85° W., and dips 30° to
45° N., with a proven length on the surface of 3000'. The Creek vein
is proven for 1500'. The ore averages $10 per ton, with assays
reported as high as $100.
The mine is equipped with log cabin, 2-stamp, triple discharge,
Union Iron Works mill and concentration plant, the latter not being
used at present, as the ore carries practically no sulphide. The mill
is run by water power from Winters Creek.
Tailings are disposed of in Winters Creek and Middle Pork Feather

Th«re is a total area, including timber rights, of 2500 acres in this
property. It is situated on the east slope of Eureka Peak from
Jamison Creek to the summit.
The mine was located in 1850 and operations began in 1851, con-
siderable work being done prior to 1875. It was closed down by the
Sierra Buttes Company in 1897, then purchased by the Johnson
Graham Mining Company and in 1909 by the present company. Onlj^
fjxploratory work was being done in 1915,

and the Lawton has been sloped for 200' above the Eureka tunnel
level. A very large area has been sloped on different veins, but it is
impossible to describe the workings without maps.
The deposit is made up of a complex system of quartz veins with
well defined walls. The main vein is at or near the contact of quartz
Iiorphyry and gabbro. At intervals flat floors of quartz are found
lying nearly horizontal. All the veins are of white free milling
quartz carrying varying percentages of sulphides, pyrite, chalco-
pyrite, arsenopyrite and galena. The Eureka vein varies from 1' to
6' in width, averaging 4', strikes southwest and dips 75° NW. The
'76' vein varies from 1' to 4' in width, strikes southeast and dips
25° S. The North vein averages 8' in width, varying from 1' to 20',

The Little Jumbo and the Plumas Jumbo claims comprise this
property. There is an area of 40 acres covering a length along the
lode of 1500'. It is situated on the ridge southwest of Mt. Adams
and contains a good stand of sugar pine and spruce.
This property was discovered in 1901 and has been worked as a
prospect off and on since that time. Idle at present.
A tunnel 125' long reaches a depth on the vein of 50'. This, with
a series of prospect shafts, makes up the development work.
The deposit forms a series of parallel veins in granite. They are
true fissure veins, with a quartz gangue impregnated with chalcopyrite,
bomite, malachite and azurite. Th^ maximum width of the vein is
6', the average being 2'. It strikes northeast, dips 45° NW., and has
a proven length on the surface of 1500'. The ore is basic.

This property consists of five claims, 100 acres in area and covering
a length along the lode of 4500'.
The mine was worked in the 70 's by G. Standart of Greenville and
is said to have produced $180,000. One hundred tons of ore removed
by underhand stoping below the Premium tunnel is reported to have
yielded $816. The mine has been idle since 1898, assessment work
only being done.
The East and West veins are developed by open cuts only. The
Premium tunnel, with a length of 460' on the vein, develops the
Premium vein to a maximum depth of 135'. The Lower tunnel is
350' below the Premium tunnel and will crosscut all three veins. It

is already in 155' and has cut the East vein, which is 20' wide and
assays $1.80. The tunnel will have to be driven 200' farther to cut
the Premium vein. One shoot has been stoped to a height of 65'
above the Premium tunnel for a width of 4' and another shoot has
been stoped to the surface, 135', for a width of 8'. Ore is said to
have averaged $11 per ton.
The three veins in this property, namely, East, Premium, and West,
are all quartz fissure veins in granodiorite, the vein filling being
quartz and decomposed granodiorite.
The ore is free milling, being oxidized and containing very little
sulphide. The East vein is 20' wide, strikes N. 50° W., dips 70° SW.,
and has a proven length on the surface of 800'. The Premium is
composed of two veins, 8' and 4' wide, striking N. 50° W., dipping
80° SW., and having a proven length on the surface of 1000'. The
West vein strikes N. 40' W., dips 70° NE., and is 3' wide. It has a
length of 400' proven on the surface and one pay shoot 140' long has
been developed.
There is an old 5-stamp mill with 600-pound stamps on the property.
Water is obtained from Crystal Lake under a 260' head, though a
much greater head can be obtained, it being possible to secure a
3300' head from Hough Creek.

160 MINES AND MINERAL RESOUBCES.
This property contains the Oriental, Reising and Pennant quartz
locations and the Reising and Rattlesnake placer locations. There is
a total of 130 acres, 71 of which are placer locations. The length
along the lode is 4215'. Narrow ridges and deep canons charac-
terize the surface.
The property was worked as a placer in early days, before the
claims were relocated. Assessment work only is now being done,
and so far it has been of little utility. It consists of an 80' tunnel
from the creek, now caved in, another tunnel run in from the ravine
east of the Reising house, which to all appearances is outside of the
lode proper, and prospecting 15' above the creek by a shallow open
cut 300' across the outcrop.
The deposit consists of two large lodes. Upper lode, 123'; Lower
lode, 157', with 150' of bedrock intervening. The lode itself consists
of a highly metamorphosed quartzite, largely charged with sericitic
mineral, and some calcite, impregnated with finely divided pyrite.
In this vein matter irregular stringers of white quartz ramify in all
directions and interbedded, well defined, large veins of quartz occur.
Small fragments of slaty rock, generally well charged with pyrite,
occur all through the vein matter, and pyrites are also found
sparsely scattered through the vein quartz. The Upper lode is more
irregular and disrupted and has less dear quartz visible. The gold
seems to be associated with quartz, which may be of later origin
than the quartzite as in some cases the 'vein^ quartz seems to cut the
cherty quartzite. Samples taken along the outcrop on the creek
averaged $1.16 for a total width of 114', and on the Lowjeir.lode $1.25
for a width of 138'. These samples were taken from hard outcrop
and there is no doubt but that the value of the ore could be materially
increased by the selection of quartz showing greater mineralization
than the whole body of the outcrop. Both the foot and hanging walls
are schists and slates. These lodes have a general northerly trend
and dip from 60° to 80° E. They have been traced on the surface at
intervals for a distance of 3000'.
Rush Creek furnishes a large and never failing water supply,
probably not less than 500 cubic feet at the lowest stage and
averaging over 1000 cubic feet. Good opportunities for the storage
of water exist at the head of the creek. For a large power supply
the waters of the river. East Branch of the North Fork Feather River,
may be utilized by electrical transmission not exceeding three miles.
A flume and ditch about 2500' in length belong to the property, with
the water privileges pertaining thereto.
The best gold prospects have been obtained from the quartz and
stringers carrying pyrite, which have in some cases been oxidized,

leaving cavities and iron-stained bands of quartz. The surface
debris overlying the lower lode was sluiced off and a considerable
quantity of angular gold, containing particles of quartz was
recovered in the sluice boxes. The pieces of gold were in some cases
quite large and the character shows that their migration has been
slight, and that they were in all probability derived from the lode
quartz.

Posey and Miller, representing Colorado men, took a bond on this
mine in September, 1915. By the middle of October the dismantling
of the 20-stamp mill and the installation of Sears-Smith rotary mills
with a capacity equivalent to 40 stamps was in progress. The shaft
was to be deepened and a six mile road from the basin to Junction
House on the Oroville road was to be built. This is the initial step
toward the development of the Granite Basin District on a large scale
by the United States Exploration Company.
In the fall of 1918 it was stated that development had proven
unsatisfactory and work had been suspended till after the war.

This property consists of nine claims, names unknown, none of
which are patented. There is a total of 180 acres with a length along
the lode of 3000'. High lava-capped peaks and deep V-shaped canons
mark the surface.
The main vein (No. 1) is developed by a 178' crosscut adit to the
vein, cutting it 150' below the outcrop, and 60' driven along the vein.
There is also a winze on the vein extending 30' below the tunnel level.
The No. 2 vein is developed by a 60' shaft with a 50' crosscut from
the bottom, and the Rose vein by a 259' crosscut adit, meeting the
vein 100' below its outcrop, with 95' driven on the vein. Drilling is
done by hand. The deposit consists of quartz veins evidently follow-
ing a siliceous porphyry dike in slates. The workings are in the
decomposed dike and no crosscuts have been run to true walls.
Nos. 1 and 2 veins, parallel and 85' apart, are made up of quartz and
decomposed porphyry containing free gold, auriferous arsenopyrite
and galena. The foot-wall of No. 1 vein is not determined, the

hanging wall is slate. It varies in width from 10' to 15'; strikes
N. T" E., dips 70° E., and has a proven length on the surface of
1000'. No 2 vein has slate walls, is 50' in width, strikes N. 10^ E.,
and dips east. The Rose vein is a quartz vein in slates with a filling
(ȣ rose quartz. It varies from 3' to 6' in width, with an average of
4' strikes north and dips east. It carries free gold and a very little
galena and arsenopyrite. No. 1 vein averages $9; No. 2, where 15'
wide, runs $4.80 a ton ; where 30' wide, it runs $3.50. The Rose mine
is a very good looking prospect, and from panning of ore appears to
be well worthy of extended development. Pinal judgment can not
be passed until the veins are crosscut and developed at deeper levels.
Masses of arsenopyrite are found, which can be burned and show a
large amount of gold. Free gold also occurs in the center of hard,
glassy looking qtiartz, not associated with sulphides nor a product of
oxidation. Galena in appreciable quantities is associated with the
arsenopyrite.
There are on the property a blacksmith shop and cabins ; a 5-stamp
Hendy mill, rock breaker and concentrator to be run by a distillate
tmgine are being installed. A tramway will be installed from the
mouth of tunnel No. 1 to the mill, a distance of 300'.

It was discovered in the early days, but no ore has been stoped as
yet, though it is a prospect with good chances.
There is a 300' shaft on the dip of the vein. A 100' drift east from
the shaft, on the 150' level, shows the vein splitting. The main wall
continues its regular course without quartz, while quartz stringers
swing into the foot-wall until the strike is nearly north and the dip

This property consists of five claims, the Atlantic, Pacific, Hibernia
and the Green Mountain timber tract (160 acres), all patented, and
the McLellan placer claim (160 acres), a location. There are 60
acres of quartz claims and 320 acres of timber and placer ground,
covering a length of 1500' on the Indiaii Valley vein and 3000' on
the South Eureka vein. It is situated on the top of the ridge south
of Greenville with good timber on the property.
G. Standart purchased the group in 1890 and it has been held in
the family up to the present time. Two men are working in the
McLellan crosscut doing assessment work. Options have been given
on this property and a number of properties adjoining and a con-
solidation is said to be under way.
The South Eureka vein has been devoloped by a crosscut 450' long,
reaching a maximum depth of 80' and 400' driven on the vein. It
has been stoped for a length of 400', a width of 12' and a depth of
80'. A tunnel 100' long has been driven on the McLellan vein,
leaching a depth below the outcrop of 350', and a crosscut tunnel
300' long has been driven on the Hibernia vein and 200' x 20' x 120'
of ore has been stoped. The Pennsylvania tunnel from the McLellan
claim into the Hibernia, 500' below the surface, will have to be driven
200' farther to cut the McLellan vein. It will also be extended to cut
the South Eureka.
The deposit is composed of three quartz fissure veins near a contact
of granodiorite and meta-rhyolite. The vein filling of all the veins
in quartz and gouge, the ore being oxidized and containing free gold.
The South Eureka vein is 12' to 14' in width, strikes N. 30° W., inter-
secting the Indian Valley vein, and dips 70° NE. The foot-wall is
granodiorite and the hanging wall is * porphyry,' probably meta-
rhyolite. It has a proven length on the surface of 3000'. Two pay
shoots have been developed 80' and 450' in length, the ore, it is said,
plating $6 to $8. The McLellan vein dips 65° E. Its walls are
* porphyry' and it has a proven length on the surface of 3500', and
two 100' pay shoots developed ore which is said to have averaged
$6 to $7 per ton.

hills are characteristic of the surface, and fair timber stands on the
property.
The mine was located in 1880 and has been worked at intervals
since that time. It was under lease in 1913 to Len Hensath of Brush
Creek, who, with an assistant, was repairing the mill.
The Specimen vein has been developed by the Showshed adit of
600', driven on the vein, and the West vein by an adit tunnel of 500'
driven on it. Ore has been stoped from the tunnel levels to the sur-
face. The Showshed adit reaches a maximum depth of 160'.
There are two quartz veins in granite, the Specimen and the West,
rather flat fissure veins, parallel and 300' apart. The ore contains
rich specimens of free gold and also 1% of sulphides. The Specimen
vein, which varies from 6" to 15", averages 1' in width, strikes north-
cast, dips 30° E., and has a proven length on the surface of 1000'.
The West vein varies from 1" to 15" in width and strikes northeast.
Pay shoots are short, but one 10' in lei^gth produced $20,000. Ore
averages $12 to $14 in both veins.
Several houses furnish living quarters, and an old 4-stamp 750-

former is quartz and recemented breccia carrying free gold, galena,
pyrite and some chalcopyrite. Both walls are slate. The vein varies
from 20' to 60' between walls, strikes N. 45° W., and dips 70° NE.
It has a proven length on this group of 2000', and also extends
through other claims. The vein carries gold throughout the 2000',
an average value of 14 samples taken from different places, being $7.
The Contact vein is filled with quartz and calcite. It is 30' wide and
strikes N. 45° W. Maximum assay value $7.
Water power on North Fork Feather River up to 10,000 horsepower
is available.
The Elizabeth Consolidated and Halstead mines are extensions of
the Summit vein to the southeast. The Duncan, Halstead and Eliza-

Quincy by good automobile road. Elevation 3800'.
Bibliography: U. S. Geol. Survey Folio 37, Downieville.
This property includes two patented claims, the T. C. and 0. K.,
40 acres in area and covering 3000' along the lode. There is fair
timber on the ground.
It has been held by the present owner since 1880, but no work has
been done on the claims for many years and their value is prob-
lematical.
This deposit consists of one vein exposed in a 130' shaft, said to
be the same as the Iowa vein of the Bell group. It is a quartz vein
with stringers following a siliceous dike, containing free gold and
pyrite. The foot- wall and hanging wall are made up of quartzite and
slate. It strikes N. 15° W., and has a proven length on the surface
of 600'.

group is situated on the northern slope of the canon of Middle Fork
Feather River, 2500' above the river. Though sparsely timbered,
excellent timber can be had within one mile of the mine. The claims
were located by Teflft in 1906 and two men are working at the
present time.
The vein has been developed to a depth of 170' by a crosscut adit
240' in length. From the point where this adit encountered the vein,
a drift was driven north within the vein for a distance of 105' and
south for 225'. The above work blocked out 10,000 tons of ore
averaging over $7 per ton. There are also 800 tons of ore on the
dump. A lower tunnel started 180' below the upper tunnel was in
a distance of 100' in 1913. It is estimated that this tunnel will have
to be driven 250' farther to intersect the vein. If the oreshoot proves
to be of the same length and width as on the level above, a drift on
the vein will develop 20,000 additional tons of ore.
The Teflft vein lies in a narrow belt of amphibolite schist between
Calaveras slates on the east and a belt of serpentine on the west.
The vein is a true fissure vein and cuts diagonally across the general
strike of the schists and slates. Its course is nearly north and the
dip is 60° W. The average width of the vein is 5', the maximum
about 8'. Both walls are an altered schist, and a clay gouge is found
on both. The vein filling is an oxidized, iron-stained 'sugar' quartz,
which contains 'rusty' gold, and is free milling. There are three
other veins on the property, which in 1913 had only been opened by
superficial open cuts, but pan samples taken from these veins all
showed free gold. The ground stands well and very little timbering
has been necessary. There are five buildings on the property, which
include a blacksmith shop and stable. An air compressor, was
installed in January, 1914.
If a mill is built, wood or oil will have to be used for fuel until
such time as water power can be developed. Transportation costs
Iff per pound from Quincy.

This property consists of four claims, the.Taft (formerly known as
the Blaine), Blue Mule, Ladlee, and Roosevelt. There is a total of
75 acres with a length along the lode of 3000'. The mine is situated
on the ridge south of Greenville and there is a fair stand of timber
on the property.
It was worked in early days and was acquired by the present
owners in 1903. Assessment work only is being done at present.
The property is developed by tunnels. The Lower tunnel is a
525' crosscut to the Ladlee vein, 600' below the surface, and 60'
drifted on the vein. The Ladlee tunnel cuts the vein 100' below the
surface, and is then driven 60' on the vein. The Blaine tunnel is a
100' crosscut with 700' driven on the vein, 400' below the outcrop.
A small amount of ore was stoped in the latter.
The deposit is supposed to be made up of two veins, but it may be
one faulted vein. It is a quartz fissure at the contact of meta-rhyolite
and diorite, the filling being quartz and 'porphyry.' It is free
milling and contains 1% of auriferous pyrite assaying $121 per ton,
and some manganese oxide. Both hanging and foot walls are made
up af 'porphyry' and granite. The vein varies from 10' to 25' in
width, strikes east, and dips 80° S. It has a length proven on the
surface, by open cuts, of 1500'. In the Ladlee tunnel the vein is 3'
wide and assays $12.50. In the Blaine the vein is said to be 4' wide
and to assay $14.
Equipment consists of a cabin, blacksmith shop and tools. Water
power is available from Round Valley Reservoir.

This property, together with the Southern Eureka group, Hibernia
and McLellan, was purchased in October, 1915, by Geo. D. Needy
and associates of Spokane, Washington, who expected to push
development. The Southern Eureka Mining Company was organized
by Spokane people, with a capitalization of $2,000,000, to operate the
properties. The group contains approximately 450 acres of mineral
ground. Geo. D. Needy, E. F. Yaeger, M. D. DeHoflf, Hal J. Cole

170 MINES AND MINERAL RESOURCES.
The property is situated on a ridge of gentle slope and consists of
two claims, the White Oak and Black Oak, 40 acres in area and
covering a length along the lode of 3000'. The timber was cut over
in early days.
Wormley has owned the property for a long time, but has been
doing assessment work only in the past 15 years.
A 200' tunnel has been driven on the vein and one crosscut to the
east, near the face of the tunnel driven 30' through slate cut
numerous quartz stringers, none, however, with well defined walls.
One vein composed of small stringers of quartz following the strike
of slates and not well defined, was worked. The filling is iron-
stained quartz and gouge, with some pulverized quartz containing
free gold.
The stringers vary from 2" to 1', the general strike being northwest
and the dip 80° E. There is a proven length on the surface of 3000'.
The Bushman drift placer mine adjoins, in which the gold has been
derived in part from the erosion of the veins and stringers on the
White Oak quartz property.

This property embraces 110 acres of locations, namely, the White
Lily quartz mine, Addie Bell quartz mine, Wedge Fraction, Whitloek
placer (60 acres) and Madison placer (old Calliope claim). It covers
a length of 3000' along the lode, and is situated on the east bank of
North Fork Feather River with a steep rise to the top of a ridge.
The property is well timbered.
It was located in 1896 by P. K. Dunn and has been worked ever
since by the Dunn family. Suit was brought by the Del Monte
Company, in 1912, because of a drift passing through the side line
of the White Lily into the Del Monte property, and the White Lily
people have been prevented by injunction from removing ore. The
total yield of the mine to date is about $225,000. Two men are
leasing and working in a part of the mine not under injunction.
Negotiations are now under way for the consolidation of the White
Lily and Del Monte properties^ The owners are said to be anxious
to sell and if satisfactory terms can be arranged there is apparently
enough ore in sight to pay for the property.
The vein is made up of quartz and quartz stringers in slates, schist
and gouge in a badly shattered zone near the contact with altered
meta-andesite and possible diorite. The vein filling is oxidized
•rushed quartz containing free gold and very little sulphide, the ore
PLUMAS COUNTY. 171
being so crushed that very little powder is necessary for breaking it.
The foot- wall is slate with clay gouge and the hanging wall is said to
be diorite. In width the deposit varies from 30' to 60', 30' being the
average width of the stopes! The strike is east and the average dip
is said to be 35° N., but at the lower tunnel level the orebody appears
to be lying nearly flat. Tailings are disposed of in North Fork
Feather River.
The mine equipment consists of houses, barns, blacksmith shop and
electric hoist. The reduction equipment includes a complete new
10-stamp 1000-pound Hendy mill. This was installed in the latter
part of 1911 but on account of the suit was never operated. There
is also an old 2-stamp mill which can be put into shape to run.
Water from North Fork Feather River to the amount of 2500"
under 30' head is available for turbines. Cost of treating ore with
the old equipment was $2.50. Tailings vary from 50ff to $1,25.

This property consists of four locations, the Jackson, Munro,
Tunnel and Lizzie (fraction), a total of 70 acres, covering a length
along the lode of 3000'. It is situated near the top of the ridge back
of Crescent Mills, 1000' above the floor of Indian Valley. There is a
fair stand of timber on the property.
In early days rich pockets were taken out from the surface work-
ings to a depth of 50'. It has been worked recently under bond by
W. W. Robbins, but is idle at present.
The vein is developed by a 60' crosscut adit, then a drift of 50' on
the vein. Pocket mining has been done for a length of 100' and to
an average depth of 50'.
There is one cherty quartz vein, really a siliceous zone with no
well-defined walls, impregnated with sulphides, marcasite, pyrite and
a small amount of finely disseminated galena. Very little free gold
has been found below the oxidized zone, a depth of 50'. Some ore
containing as high as 5% sulphide, goes $200, but the best values are
in ore containing galena. The walls are siliceous rhyolite. The ore
zone varies from 8' to 10', but the sulphides are not equally dis-
tributed. The strike is N. 32° W., the dip vertical and there is a
proven length on the surface of 300'. No distinct pay shoots
developed.
There is a blacksmith shop at the mine.

This property consists of three claims, two of which are patented,
containing 60 acres and having a length along the lode of 4500'. It
is situated on the west side of Fall River and has good tunnel sites
and a good stand of timber.
It was discovered in 1888 by Jack Moore and purchased by Wolters
and Company in 1889. There has been a total production of
about $2000.
The property is developed by a 700' tunnel to the first vein, which
is then continued 150' to strike the second vein, on which there is a
50' shaft, and drifts 100' south and 250' north. Two shoots of 50'
and 100' were stoped for an average width of 4'.
The deposit consists of quartz fissure veins containing free gold,
chalcopyrite and pyrite. The foot-wall is porphyry, the hanging waU
granite. The vein varies from 4' to 6', strikes northeast and dips
45° W. There is a length proven at intervals on the surface of 700'.
The pay shoots, stoped, milled $6 to $7 per ton; and carried 4% sul-
phides assaying $50 to $150 per ton. Two hundred inches of water
under 80' head are available from Fall River.

Development consists of two tunnels 150' and 145' in length, imder
the lava, and a 22' shaft put down 150' beyond the end of the
145' tunnel.
The deposit represents present river gravels, eroded from rocks of
the bedrock series and lava gravel, running east. Bedrock has not
been reached, as too much water was encountered in the shaft. The
deposit is capped with andesite and basalt. The gravel is fine, but
has some large boulders in it. A portion lying on 'hardpan' to a
depth of 7' is said to have averaged 16^ to 24^ per yard. No test
pits or drilling have been done, and until some work has been done,
the value, depth, etc., are problematical. Surface gravels can only
be worked profitably by dredge or dragline scraper.

This property comprises 40 acres of locations in the creek bed just
above Johnsville. It has a length along the channel of 3000'.
The claims were relocated by the present owner in 1909. About
20 acres of the property was worked in early days. Assessment work
only being done at present.
The deposit consists of free glacial and creek gravels, with some
boulders. They are the surface gravel of Jamison Creek, the gold
being derived from the erosion of the Plumas Eureka and Jamison
'/eins. The channel courses north.

Property consists of 940 acres. High ridges with steep slopes to
watercourses characterize the surface.
The ground was first located in 1896, was relocated by the present
owners in 1908. Assessment work only has been done. The deposit
is crossed by the Western Pacific Kailway at Virgilia, and if it will
average CaCog, as the sample shows, it is undoubtedly of commercial
value.
A 142' open cut across the deposit is the only work that has been
done, and so far this has not encountered the west wall.

Braito Mine. Owners, Fred E. Braito and T. J. Mason, Crescent
Mills. Comprises one claim in Sec. 26, T. 26 N., R. 9 E., M. D. M.,
near Crescent Mills.
The ore body lies in schist and strikes northwest. It is developed
by open cuts and a tunnel, which showed mixed ore for a width of
4' to T.
During 1917 the property was under lease to the Noble Electric
Steel Company. They employed 30 to 40 men and up to January 1,
1918, had shipped 20 carloads of ore to their Heroult smelter.
Burch and Woody Prospect is near the line of Sees. 21 and 28,
T. 26 N., R. 9 E., four miles west of Crescent Mills. When the prop-
erty was visited in 1917, a small amount of manganese oxide, which
was too siliceous to sell, had been taken out.
Crystal Lake Manganese Group, known also as the Mt. Hough, is
owned by H. A. and R. L. Kloppenburg and H. S. Myton of Quincy
and leased to Smith Brothers of Taylorsville, who bought the lease
from Allen and Robinson.
The group comprises three claims in Sec. 8, T. 25 N., R. 10 E., on
Mt. Hough, five miles east of Indian Falls. Half a mile of road was
required to reach the deposit.
Allen and Robinson shipped ten cars of ore from the property
before selling their lease. Smith Brothers report shipments of seven
or eight carloads during 1918, and expect to keep up production
during 1919.
The ore could be traced for 200' along the strike, N. 42° W. When
visited, an orebody 6' wide and pitching 80° SW., was exposed. It
is said that the ore from this property carries from 50% to 54%
metallic manganese, which would make it equal in grade to any in
the state. It has been sought after for use in dry batteries.
*From Bulletin 76, Calif. State Mining Bureau, August, 1918.
180 MINES AND MINERAL RESOURCES.
Diadem Lode is one of a group of three claims which include 20
acres in Sec. 33, T. 24 N., R. 8 E., fourteen miles southwest of Quincy.
Manganese oxides and rhodonite are reported to occur in a quartz
vein on this claim associated with iron oxide. The vein strikes N.
37° W. and dips 60° NE.
No development work for manganese had been done at time of
visit and it is believed that the deposit is only superficial.
Iron Queen Claim was located by Chas. Devlin and A. F. Smith in
Sec. 8, T. 26 N., R. 9 E., about six miles northwest of Crescent Mills.
Two small, short open cuts had developed a little good ore, bul most
of the manganese oxide was too siliceous.
The Penrofle Mine, on Mumford Hill, three miles southwest of
Meadow Valley, near Edmanton, shows an occurrence of manganese
oxides in the gossan of a quartz vein similar to that at the Diadem
lode. The deposit is probably superficial.
MOLYBDENUM.i
The Dufay and Eyhi properties near the Mohawk mine (about eight
miles northwest of Chilcoot) have been worked for copper ores which
are said to carry some molybdenite. Some ore was shipped by Dufay
in 1915, but apparently no use was made of the molybdenite con-
tained.
Mohawk Mine. The ore at this copper property, which lies eight
miles by road northwest of Chilcoot, is said to carry a small amount
of molybdenite, but none of it has been recovered separately.
Murdock Mining Company. The property contains nine claims
located nine miles northwest of Chilcoot and a mile beyond the
Mohawk. Shoots of molybdenite ore occur here in quartz veins
which carry principally bornite and chalcopyrite. Two tons of high
grade molybdenite were picked out of the dump and shipped by lessees
in 1916, but no production has been reported since. The vein prin-
cipally developed is 3' to 4' wide, and it is said that it can be traced
for over half a mile. A more detailed description of the mine is given
under Copper.

STONE INDUSTRY.
The Chilcoot Granite Company. R. B. Myers, manager, 204 Bacon
Block, Oakland, owns a granite quarry near Chilcoot on the Western
Pacific Railroad, but it has not been operated recently.
Paul Sonognini, at Chilcoot, has a granite quarry which he has
operated in a small way for several years past, but it was idle in 1938.
The Western Pacific Railroad, at several places along their right
of way in Plumas County, but principally near Chilcoot, utilizes
granite for rubble and ballast. A ditcher, Rodger's ballast, and flat
cars are used.
