MINING DISTRICTS-

ALLEGHANY MINING DISTRICT.

Including Alleghany, Forest, Chips Flat and Minnesota.
Introduction.

The Alleghany district is one of the older California gold camps,
famous in early days for rich placer and drift mines. Miners working
gold quartz veins often find extremely rich ore shoots which present
interesting problems in vein formation.

Situation, etc.

The district is situated in the southwestern part of Sierra County,
twenty-five miles northeast of Nevada City. Alleghany may be
reached by stage from three railroad points — ^from Nevada City via
Mountain House (forty miles) ; from Loyalton and Truckee on the
northeast and southeast, respectively, via Downieville and Mountain
House. A regular daily stage from Nevada City is the shortest route.
The stage roads are poorly located in regard to rain and snow,
causing the region to be isolated during winter. The freight rate
from Nevada City to Alleghany is $20 a ton. The Nevada County
Narrow Gauge Railroad terminates at Nevada City, and the Southern
Pacific Railroad connects with the other points.

The climate is characterized by heavy rains and deep snow in
winter, and by dry, warm summers. The growth of yellow pine has
been almost completely cut, but there are still large areas covered
with timber on the ridges south of the South Fork of Yuba River and
on the North Bloomfield divide.

The Alleghany district was one of the first placer regions to be
worked in California. The rich river bars were mined first, after
which hydraulieking and drifting in ancient gravel beds of Neocene
age was carried on. Lode mining became important in 1907 after
the discovery of the Tightner vein at Alleghany. The total gold
production to 1913 is estimated at between $5,000,000 and $6,000,000 ;
in 1912 it amounted to $293,561.

Topography.

The topography is characterized by streams separated by gently
rolling areas. The river canons are deep and precipitous. Alleghany
and Chips Flat are on opposite slopes of the canon of Kanaka Creek,
a branch of the Middle Fork of Yuba River. The northern part of the
district, about Forest, is drained by Oregon Creek. A broad andesite

2 MINES AND MINERAL RESOURCES.

breccia ridge between Oregon and Kanaka creeks is about 1000' above
the general level, with a moderate slope on the south side. The
general elevation of the region is from 4000' to 5000'.

Geology.

The region consists' off intensely folded sedimentary rocks, intruded
by basic igneous rocks; andesite breccia covers both igneous and.
sedimentary rocks in certain areas. The sediments and intrusioiis
were eroded before the andesitic flow took place and fragmentary
areas of the andesite are sometimes underlain by old Neocene gravel
beds. Slates and sandstones are exposed as parallel bands running
approximately north and south. A band of Cape Horn slate one mile
wide lies to the west, while the Blue Canon formation, which is three
miles in width, lies to the east. The general strike of the beds is
north with dips of 80° to 90° E. The Delhi formation is com-
posed of a dark brown, hard, fine-grained rock, and occurs in contact
with serpentine near the southwest border of the district.

The Cape Horn and Blue Canon formations are separated by.
serpentine and amphibolite. Compressive stresses have caused the
igneous rocks to be schistose in character, especially the amphibolite
which has probably been derived by pressure, from diorite or gabbro.
In some places the amphibolite schists are chloritic and diflScult to
distinguish from clay slates.

West of Alleghany the serpentine consists of four parallel narrow
bands in amphibolite. Along Oregon Creek a serpentine belt encloses
a mass of gabbro ; the surface exposure of this belt is broken on the
ridge south of Oregon Creek by a capping of andesite breccia.

Historical geology.

The oldest known rocks in the region are those of the Blue Caiion
and the Cape Horn formations, which belong to the Carboniferous
division of the Paleozoic. The former is composed of gray slates and
quartzitic sandstones, while the latter is composed only of clay slates.
The Delhi formation in the southwestern part of the district rests on
Cape Horn slates which are known as the Calaveras formation in
other regions.

At the end of the Carboniferous period the sediments were closely
folded and compressed. Erosion took place during the Juratrias
period, at the end of which the sediments were folded into high moun-
tain ranges. Intrusions of basic and igneous rocks occurred at about
the same time. The principal ore deposits followed these intrusions.

A period of folding and faulting occurred again in late Cretaceous
time and* the high Sierra Nevada range was formed. Deposition,
following erosion, built up auriferous gravels in the river beds of the

I:

;l]t

SIERRA COUNTY. 3

Neocene period ; some of these have been covered by andesite breccia
which flowed down the Neocene river valleys, at the close of the
Tertiary period, as volcanic mud. Andesite covers the chief inter-
stream ridgea and has preserved many of the auriferous gravel
deposits from being eroded.

Mineral depoiiU.

The mineral deposits occur both as lode and placer. The lode
deposits are well-marked fissure veins. The placer deposits are
covered by andesite and recent river bars.

Tertiary grave it.

A tributary of a Neocene river runs through Minnesota, Chips Flat,
Alleghany and Forest. At Minnesota 20' of fine quartz gravel is
exposed. The channel below the andesite has been drifted along its
satire length and was found to be very rich. At Chips Flat a few
acres are exposed, consisting of coarse gravel with well-washed
quartz boulders. At Smith's Flat, one mile south of Alleghany,
gravel banks 50' high show flat cobbles of quartz and siliceous slate
on bedrock. The gold is coarse and has often worked its way down
into bedrock. At Forest, $150,000 is reported to have been produced
i'rom a small amount of heavy gravel; one foot of bedrock was
extracted with 2j' of gravel, yielding $7 per cubic yard. Drifting
fiperations have been carried on in a small way at various points
along the ridge west of Alleghany. In general the Neocene gravels
were deposited in branches of a great drainage system that sloped to

tfie Sacramento Valley. Both bedrock gravel and bench gravel con-
tain gold, but the former is richer. Gravels intercalated with
andesite tuff seldom carry values.

The gold probably accumulated during erosion of the various quartz
veins of the region. In some cases the Neocene gravels themselves
have been eroded, and the gold reconcentrated in modern streams;
an example of this is the shifting bars of Kanaka Creek and the
Middle Fork of Yuba River.

Lodo deposits.

The gold quartz veins are mineral fillings of fissures in the bedrock
(pre-Cretaceous) series. Quartz has been deposited by waters circu-
lating in the fissures, which vary in size and regularity. A large vein
eiten splits into a series of stringers, especially when passing from
amphibolite into serpentine. The gold is seldom evenly distributed,
usually being concentrated in bodies or in elongated steeply dipping
ore-shoots, several of which may occur along a vein. Productive
veins occur in slate, serpentine and amphibolite, but chiefly in the
latter. They strike north, northeast and east, and dip from 40°
to 60° E.

The veins in the amphibolite are generally persistent but vary in
width. There is usually a well-defined wall, where they pinch out,
with some gouge which may be followed until the quartz reappears.
Serieite occurs in minute veinlets within the veins, especially in the
crushed portion. Secondary dolomite and siderite are sometimes
found as crystals formed on the quartz.

Arsenopyrite occurs in the veins as large-bladed crystals, and as
irregular masses broken and veined by quartz. It is the most impor-
tant vein sulphide, as it contains gold and is an indicator of rich ore-
shoots. Banded quartz is regarded as a favorable indication for good
gold values; the arsenopyrite in such ores occurs as bands and has
been recrystallized in minute perfect octahedral crystals. Fine
crystalline arsenopyrite found in veins some distance from the shoots
of high grade ore usually contains only small amounts of gold. The
gold ranges in size from microscopic particles to pieces several milli-
meters across. It occurs as thread-like veinlets and as replacements
of the quartz veinlets which cross the arsenopyrite. It also occurs in
small irregular fissures, away from the arsenopyrite, usually asso-
ciated with galena. The galena is not abundant but is commonly
associated with rich ore. It often occurs as a replacement of quartz,
one crystal being the center of radiation of closely spaced slender
galena needles, about two millimeters long. ^linute crystals of dark
brown sphalerite often occur with the galena and pyrite is found
associated with the other sulphides. Tetrahedrite and chalcocite

SIERRA COUNTY. 5

occur in small amounts. Minerals occurring in the wall rock are
calcite, dolomite, mariposite, arsenopyrite and pyrite.

As shown by the microscope,* arsenopyrite crystallized before the
quartz and the gold is deposited later than the arsenopyrite. The
coarsely crystalline arsenopyrite carries gold; apparently the gold
was carried in later solutions traveling through the vein and was pre-
cipitated by the arsenopyrite. Near the arsenopyrite, gold and
various sulphides, such as galena, were deposited in minute fissures.

AMERICAN HILL MINING DISTRICT.

This district includes the country within two miles of the town of
American Hill. The region contains both lode and placer deposits,
but mining has been done chiefly in the Tertiary river gravels, which
are especially rich in the region of the quartz veins. It is in south-
western Sierra County, about five miles east of Alleghany, and thirty-
one miles northeast of Nevada City. The nearest shipping point is
Nevada City, terminus of the Nevada County Narrow Gauge Eailroad,
from which a daily stage is run to Forest. The distance from Forest
to American Hill is about six miles over fair roads.

The summers are warm and dry, but there are heavy rains and
snowfall in the winter. This region is but sparsely timbered. Wolf
and Bear creeks furnish a good supply of water.

Topography.

The region in general consists of rolling interstream ridges.
American Hill (elevation 5000') is situated on a flat topped ridge
covered with andesite which lies between two branches of Wolf
Creek. The canons of Wolf and Bear creeks, which drain the region,
are from 1000' to 1500' de^p.

Geology.

The formations consist of closely folded Blue Canon slates and
quartzitic sandstones, intrusive granite, and andesite and basalt flows.
The Blue Canon is the oldest formation, being of Carboniferous age.
The granite intruded in early Cretaceous or late Jurassic time.
Stream gravels accumulated during the Neocene period and at its
close much of the region was covered by volcanic andesite breccia.
In early Pleistocene the partially eroded andesite was covered in
places by local basalt flows.

6 MINES AND MINERAL RESOURCES.

The basalt is fine grained, sometimes vesicular, and generally eon-
tains small crystals of olivine. The granite is coarse grained and of
light gray color. It consists of white feldspar with large crystals of
gray quartz, with small amounts of hornblende and biotite. Other
rocks present are the same as in the Alleghany District.

The Tertiary gravels are characterized by coarse gold. At
American Hill and extending for a mile westward around the head
of Little Wolf Creek bench gravels outcrop. On the east side of
Wolf Creek, at Bunker Hill, a gravel bed 300' thick lies in a trough
in the bedrock and is covered with clay and sand. This channel is
believed to extend under the lava cap. Two long tunnels, driven
some years ago, but now inaccessible, showed the existence of two
channels at different elevations.

There are two known quartz veins in the district, one directly
south of American Hill, and the other about a mile in a southeasterly
direction. Their outcrops strike northerly and may be traced for
perhaps a quarter of a mile. The first vein dips 80° E ; it is a fissure
vein in Blue Canon slate. The southern vein appears to occur along
a contact between slate and granite.

BRANDY CITY DISTRICT.

The Brandy City mining district is located in the extreme western
portion of Sierra County, twelve miles by trail west of Downieville.
It comprises the auriferous gravels of the west fork of the Neocene
channel of North Yuba River, which have been worked for gold since
the early fifties. Brandy City is situated at an elevation of about
3700' on the southwest end of a gently sloping ridge. Clipper Mill,
eight miles by trail west of Brandy City, has stage connection with
Oroville, thirty-four miles distant, and Quincy, fifty miles distant.
Downieville is about forty-eight miles, by stage, southwest of Loyal-
ton, a point on the Western Pacific Railroad; also about sixty-eight
miles by stage northeast of Marysville, and about forty-four miles
north of Nevada City. During the spring and summer months the
stage roads and trails are fair, but during the winter months, owing
to heavy rainfall and snow, they are very poor. Sufficient water for
that portion of the district immediately around Brandy City has been
obtained from Canon and Cherokee creeks. Rock and Slate creeks
furnish water for the section north of Brandy City.

History of mining.

The deposits of auriferous gravels belonging to the La Porte
channel have been hydraulicked. Operations on a large scale were
carried on at Poverty Hill in the extreme north of the district until

- ■■■'Axu^

1891. In 1906 and 1907 the gravels of Poverty Hill were prospected
with the idea of working them by drifts.

Opposition to hydraulic mining in 1891 stopped large operations
carried on along the channel between Canon Creek and Cherokee
Creek. The Brandy City Mining Company later obtained control of
the water rights and most of the claims. Water is carried by ditches,
under the supervision of the U. S. Debris Commission, and in 1909,
30,000 cubic yards of the upper part of the gravel was hydraulicked
with a recovery of lOff per cubic yard.

Topography.

Slate Creek, to the north of this district, flows along the north-
western side of a ridge, and Canon Creek flows along the southeastern
side of the same ridge. The canons formed by the two creeks are
steep and precipitous. On the ridge are the Council Hill, Pairplay,
Union Hill, Scales and Poverty Hill diggings.

Brandy City, Grizzly Hill and Indian Hill diggings are situated on
a ridge lying between Canon Creek to the northwest and the North
Fork of Yuba River to the south. The district is drained by the
North Fork Yuba River, and its tributaries.

Geology.

Amphibolite composes most of the exposed portion of this district.
An area of Calaveras slate is in contact with it on the north. Small
exposures of andesite tufif cap the auriferous gravels at Poverty Hill
and Union Hill. At Council Hill, near the line of contact between
the amphibolite and the Calaveras formation, a small exposure of
andesite tuflf caps the auriferous gravels. A strip of the Calaveras
formation about one-fourth mile wide extends through the amphibo-
lite north of Brandy City and trends in a northerly direction. A
portion of this, as well as a considerable portion of the amphibolite,
is capped by andesite tuflf north of Brandy City. A narrow strip of
serpentine cuts through the amphibolite and is in contact with
andesite tuflf and the underlying auriferous gravels at Brandy City.
Southwest of this serpentine is an area of Calaveras slates, trending
southerly, in contact with amphibolite. On this exposure of the Cala-
veras formation is found the auriferous gravels of Indian Hill. A
small exposure of gabbro occurs about one mile southeast of Brandy
City.

8 MINES AND MINERAL RESOURCES.

The auriferous gravels of the district are all of Neocene age. The
main channel extends from the Poverty Hills inlet of Scales Diggings,
reappears at llock Creek outlet and continues to Union Hill, Fair-
play, Council Hill, Brandy City, Grizzly Hill and Indian Hill.

DOWNIEVILLE MINING DISTRICT.

Including Downieville, Goodyears Bar, Eureka, Sierra Turnpike and Cornish

House.

The Downieville district includes large deposits of recent aurifer-
ous gravels, along the North Fork of Yuba River and its branches,
from which millions of dollars have been washed; the most valuable
deposits are exhausted. Tertiary auriferous gravels occur in two or
three scattered areas. The district is one of the largest producers of
placer gold in the region. Small amounts of gold have been obtained
from two or three quartz veins. A lens of dolomitic limestone in the
extreme eastern part of the district extends northwesterly from the
North Fork of Yuba River for about one mile in length.

Downieville, the county seat, is situated at an elevation of 3000' in
the west-central portion of Sierra County. It is forty-four miles by
road north-northeast from Nevada City, via North San Juan and
Camptonville. The distance by road from Marysville, in Yuba
County, is sixty-eight miles. Downieville may also be reached from
Loyalton, forty-eight miles by road to the east on the Western Pacific
Railroad.

The climate of the district is moderate. The summers are warm
and dry, but during the winter months there is heavy rainfall and
some snow. It is in the central portion of the Tahoe National Forest
and is wooded with yellow and sugar pine, spruce, fir and oak. The
region has an abundant water supply. The North Fork Yuba River
and its tributaries run through the district and furnish a cheap source
of electric power.

History of mining.

Gold-bearing gravels of modern streams were worked at an early
date. Tertiary auriferous gravels were mined by a shaft at the
Pliocene mine, four miles south of Downieville. At the Ruby mine,
one mile north of Table Mountain and three miles south of D(>wnie-
ville, gravels have been mined by means of a tunnel. At the head of
Slug Canon, two miles south of Downieville, the City of Six gravel
deposits occur where an old river channel has been tunneled through
to Rock Creek, a tributary of the North Fork Yuba River to the west.
The Bald Mountain Company has worked its channel by tunnels that
enter the ridge on the south slope. The gravel of the Nebraska

SIEERA COUNTY. 9

diggings, two and a quarter miles southeast of the Pliocene shaft,
has been extensively mined. In 1905 the Downieville district pro-
duced $34,000 in placer gold; in 1909 the production dropped to
$17,000.

Topography.

Downieville is located at the juncture of the North Fork of the
North Fork with the North Fork of Yuba River. The land rises
from Downieville in three directions. To the northwest the eleva-
tion increases from 3000' to 5000' in less than two miles. To the
northeast the canon sides are most steep, the slope being greater
than 1:1, and the elevation reaches 5500' along the ridge. This
ridge runs parallel to the North Fork Yuba River, and forms the
divide between it and the. East Fork of the North Fork; south of
Downieville the land rises to a long level ridge trending east between
the North Fork and the Middle Fork of Yuba River ; at Table Moun-
tain it reaches an elevation of 5619'.

Geology.

The region is made-up primarily of folded and compressed sedi-
mentary rocks of the Calaveras formation, which have been meta-
morphosed to clay-slates and quartzites. Intrusions of serpentine,
gabbro and amphibolite have taken place in the western part of the
district. The serpentine extends north and south as long belts
through the district. It is covered with andesite on Fir Top Moun-
tain, but is exposed on the eastern slope of Saddleback Mountain
farther to the north; it makes up the east slope of Goodyear Creek
Canon. In the southeastern portion of the district a large intrusion
of granite occurs in the Calaveras formation.

One-half mile east of Downieville a long narrow dike of gabbro
intrudes the Calaveras formation; it is about two miles long and
extends in a northwesterly direction. Near its northern extremity
the Gold Bluff quartz vein occurs.

Eureka is located five miles by trail northwest of Downieville. It
.is on Neocene gravels which rest on a belt of augite-porphyrite less
than one-half mile wide enclosed by the Calaveras formation. The
augite-porphyrite was probably derived from augitic tuffs, lavas and
dikes of Juratrias age, compressed and metamorphosed along with
the surrounding sediments.

10 MINES AND MINERAL RESOURCES.

The Calaveras formation composes the country west of Eureka.
On the upper portion of the broad flat ridge furthest west there is a
capping of andesite breccia continuous with the andesite running
southwest in Poverty Hill district.

During Eocene time the Sierra Nevada was eroded, and during the
Neocene period auriferous gravels accumulated. At the end of
Neocene time extensive lava flows occurred, a remnant of which is
the andesite breccia remaining on the highland in the south of
Downieville district. About the same time a great dislocation
occurred along the eastern base of the Sierra Nevada, which changed
the grade of the western slope of the range and greatly increased
erosion. Eruptions of basalt occurred in early Pleistocene time and
cover many scattered areas such as the Table Mountain region.

Mineral deposits.

On the high ridge south of Downieville auriferous Tertiary gravels
occur capped with andesite. There are two distinct channels. The
older one extends toward the Bald Mountain Extension mine channel.
The younger channel lies 116' lower and connects with the old Rock
Creek diggings. At the Pliocene mine, a shaft was sunk through the
andesite breccia to the gravel resting on Calaveras bedrock, and at
the Ruby mine, three miles south of Downieville, a tunnel was put in
at the base of the andesite breccia.

The City of Six gravels occur at the head 'of Slug Canon, at the
base of andesite and basalt, the bedrock being Calaveras slate. The
exposed material is 500' wide and one-third of a mile long, with
pebbles composed of quartz and metamorphic rock.

Tertiary river gravels three miles northwest of Downieville have
been hydraulicked at the Monte Cristo mine, at the Excelsior mine,
one mile northeast of the latter on the opposite side of the andesite
cap, and at two places on the ridge between the North and Middle
Forks of the North Fork Yuba River. This ridge also contains the
Wide Awake drift which extends under the andesite cap.

Auriferous gravels of recent origin occur along the North Pork of
the North Fork of Yuba River to a point five miles north of Downie-
ville. They occur at the river junction at Downieville and in dis-
connected patches in each direction along the North Pork of Yuba
River. The deposits are extensive at Goodyears Bar and for two and
one-half miles up Goodyear Creek. Water- worn pebbles of chrome*
iron have been found in the gravels of Goodyear Creek; these have
apparently been washed from the neighboring serpentine.

Recent gravels also occur along the Middle Fork of the North Pork
of Yuba. Some of these now lie at an elevation of 150' above the

SIEERA COUNTY. 11

river. At Downieville remnants of gravel benches, formerly mined
with good returns, are still preserved.

Two gold-quartz veins have been developed in the canon of the
North Fork of the North Fork of Yuba River, about a mile north of
Downieville. The veins are quartz fillings in the Calaveras forma-
tion, one being of the contact type. The outcrop extends for one-
fourth of a mile in a north and south direction. At the Good Hope
mine, west of and about 500' above the river branch, a contact vein
between slate and serpentine, strikes northwest and dips 45° W.
into the hill. The Gold Bluff vein occurs farther north on the
opposite side of the creek ; it is being worked near the north end of the
gabbro dike east of Downieville. Quartz veins are numerous on the
ridge south of Downieville and prospectors have discovered four
gold-quartz veins in Jim Crow Ravine.

GIBSONVILLE MINING DISTRICT.
Including Gibsonville and Whiskey Diggings.

This district contains extensive exposures of Tertiary auriferous
river gravels. Gibsonville has been only a moderate producer of
gold. Some chrome has recently been produced.

This district is located in the northwest comer of Sierra County.
Gibsonville is sixty-eight miles by road northeast of Marysville,
twenty-six miles by road south of Quincy, and approximately thirty
miles by road west of Clio, a point on the Western Pacific Railroad.
The condition of the roads in summer permits of the use of auto-
trucks, but in winter there is a great deal of rain and snow, and the
roads are often impassable. A daily stage runs from Marysville.

Gibsonville is a few miles north of the Tahoe National Forest, and
a great deal of timber is still uncut in the surrounding region. A
good supply of water is furnished by Little and East branches of
Slate Creek, and their numerous tributaries. Electric power is
furnished at a low rate.

History of mining.

Nearly all the main Tertiary river channel between Gibsonville
and the old Hepsidam camp has been mined by means of tunnels.
From 1875 to 1895, the Niagara Consolidated Company drifted on the
channel between Hepsidam and Bunker Hill, a distance of about a
mile. The channel at Hepsidam between rims was 800' wide, of
which 500' to 600' was drifted. The recovery from much of the
drifted ground was as high as $3 a cubic yard. One and a half miles
southwest of Gibsonville the Feather Fork Gold Gravel Company has
drifted for one mile up the channel from the Thistle shaft, which is
said to have been pumped dry at great expense.

12 MINES AND MINERAL RESOURCES.

In the region about Gibsonville and Whiskey Diggings 2,500,000
cubic yards of gravel are reported to have been washed, and in 1891,
500,000 cubic yards were estimated to be still available. In the year
1905 Gibsonville produced $6600 and La Porte $18,000 worth of
placer gold ; in 1909 both together produced $32,000.

Topography.

This small district lies mostly on the south slope of a flat ridge
between South Fork Feather River and Slate Creek, a tributary of
the North Fork Yuba River. Gibsonville is at an elevation of 5000'
on the south slope of the ridge and is 200' above the bed of Little
Slate Creek, which flows southwestward.

Geology.

The southern portion of the district is composed of amphibolite,
continuous with- that in the Port Wine district to the south. East of
Gibsonville serpentine and Calaveras slates and quartzites occur in
contact with the amphibolite. Along the ridge north of Gibsonville
fmd Whiskey Diggings a capping of andosite covers the amphibolite,
serpentine, and the Calaveras rocks.

One mile southeast of the Hepsidam drift a dike of quartz-porphyry
intrudes the Calaveras formation ; it outcrops for over one-fourth of
a mile and strikes northwest. A small body of glacial detritus
remains three-fourths of a mile south of the Hepsidam drift.

Mineral deposits.

The only mineral of economic importance at the present time is
gold which occurs in the gravels of the Neocene river channels.
The main Tertiary river channel west of the Neocene divide in the
Downieville quadrangle passes through Gibsonville, Whiskey
Diggings and Hepsidam. From Gibsonville the channel slopes
southwestward through La Porte, Scales and Indian Hill, toward
Camptonville.

From Gibsonville to La Porte the channel is deeply covered by
andesitic tuffs and clays. At the Thistle shaft, one and one-haH
miles southwest from Gibsonville, the clays composed largely of
volcanic mud, become from 300' to 400' thick; the channel is 1500'
wide and the rims rise very steeply. Similar conditions hold between
Gibsonville and Hepsidam.

SIERRA COUNTY. 13

Following up the channel from La Porte to Gibsonville the average
present grade 'is about 80' to the mile; from Gibsonville to Whiskey-
Diggings it is about 250' to the mile, and from there to Hepsidam
about 400' to the mile. Although the grade of the channel between
Gibsonville and Hepsidam greatly increases there is no change in the
character of the gravel; the rapid increase in grade is ascribed to a
differential elevation toward the east. From Thistle shaft to Hep-
sidam the channel is easily accessible by tunnels, having been mined
almost continuously.

The channel has been mined continuously underneath the ridge,
two miles above Gibsonville, by the Niagara Consolidated Mining
Company. It is 800' wide between rims, 500' to 600' of which was
drifted. The gold on the bedrock was coarse and the upper gravels
carried some gold in places. Much of the drifted ground yielded as
much as $3 per cubic yard. Several sudden * jumps* of 3' or 4' each
occur in the channel and probably represent faults crossing the bed-
lock. Under the summit of the ridge a sudden drop occurred,
necessitating another tunnel 50' lower; this was found to be the
beginning of a fault zone which depressed the channel on the Nelson
Creek side by several hundred feet. This fault zone lies approxi-
mately in the extension of the Spanish Peak fault, in the Bidwell Bar
quadrangle, but they can not be connected with certainty.

There is another fault zone in the region of La Porte. The block
between these two zones, which includes the channel from La Porte
to Hepsidam, has been sharply tilted.

The Bunker Hill drift, across the ridge in Plumas County, is a mile
and a quarter northeast of Hepsidam. There the channel is exposed
imder the lava-capped ridge, on the slope to Feather River. The
channel between Bunker Hill and Hepsidam has been mined by drifts.

INDIAN HILL MINING DISTRICT.
Including Indian Hill and Snowden Hill.

This district is situated in the west central portion of Sierra County.
Indian Hill lies a mile and a half south of the North Fork Yuba River
and ten miles southwest of Downieville. It is fifty miles, by road,
northeast of Marysville; and forty miles, by road, north of Nevada
City. There is an abundance of water, timber and cheap electric
power.

Gold is produced chiefly from mines in Tertiary and modern stream
gravels. Hydraulic mining was at one time extensively carried on.
One quartz vein, containing gold, is as yet merely a prospect.

14 MINES AND MINERAL RESOURCES.

Topography.

Indian Hill is situated in a saddle of a ridge 900' in cflevation above
Indian Valley. The level floor of this valley is somewhat less than
one-fourth mile in width and is about three miles long.

No streams of importance from the south flow into the North Yuba
at Indian Valley, but to the east Humbug Creek and St. Catherine
Creek flow from Snowden Hill. On the east side of this hill Woodruff
Creek flows northward to Goodyears Bar. Fiddle Creek drains the
region north of Indian Valley and almost parallels the North Yuba
to within three-quarters of a mile from their junction.

Geology.

The Calaveras formation makes up most of the eastern portion of
the district. Amphibolite and serpentine form the eastern border,
intrusions of granite, amphibolite and serpentine with some augite-
porphyrite occur in the west. Flows of andesite and basalt occur in
the southeastern portion of the district.

PIKE MINING DISTRICT.
Including Tippecanoe, Grizzly Gulch and Nelson Mill.

Gold occurs, in this district, in small scattered areas of Tertiary
river gravels. At Tippecanoe a few acres of Tertiary auriferous
gravels have been hydraulicked. A quartz vein at the Alaska mine,
one-haH mile north of Pike, was worked to a considerable extent
thirty-five years ago.

Pike is situated in the extreme southwest corner of Sierra County
at an elevation of 3300'. A good water supply is furnished by
Oregon Creek, Grizzly Creek and the Middle Fork of the Yuba River.
Various uncut bodies of timber in the surrounding country are
sources of lumber. The nearest railroad station is Nevada City,
twenty-eight and a quarter miles to the south, by way of Campton-
ville. Marysville, on the Southern Pacific Railroad, lies fifty-three
miles by road to the southwest.

Topography.

The region is made up of many small ridges and divides. Pike
occupies a flat ridge which extends about a mile and a half southward
and then drops 1200' in one-half mile, to the Middle Fork Yuba River.
Grizzly Creek drains Pike and the region to the southeast. To the
north of Pike the land rises to an elevation of 4000', forming the

SIERRA COUNTY. 15

divide south of Oregon Creek; this creek is a long tributary almost
paralleling the Middle Fork Yuba. River and draining the northern
region about Tippecanoe and Forest. Tippecanoe is on a broad ridge
drained by Indian Xjreek to the south. .

Geology.

Diabase occurs around Pike. North of the diabase a broad belt of
serpentine is in contact with Delhi Tocks on the east; it carries
irregular bodies, of amphibolite. In the northeastern part of the
district, north of the andesite cap, and? in contact with the Delhi
formation to the west, there is an intrusive body of granite-porphyry.

The region is composed largely of black siliceous folded sedimen-
tary rocks of the Delhi formation, pierced by the above intrusives.
Both sedimentary and intrusive rocks forming the present interstream
ridges are usually capped by andesite, which also covers the aurif-
erous gravels which were deposited in channels of rivers during the
Neocene period. Pleistocene erosion has left this andesite only on
the uplands.

Mineral deposits.

A Tertiary river channel almost coincides with Oregon Creek.
Areas of gravel exposed along this channel at Tippecanoe lie in flat
benches sometimes less than 100' above. the present stream. At
Tippecanoe the deposit is 100' thick and consists of quartz and chert
pebbles, often imperfectly washed; no volcanic rocks are contained
in the deposit. A small body of gravM is exposed one-half mile east
of Nelson Mill. Another gravel deposit one mile east of Plum Valley
rests on a bedrock of the' Delhi formation and is capped with andesite
to the northeast. Some drift mining rhaCbeeii done three and three-
quarter miles northeast of Pike, in. a gravel deposit resting on
serpentine.

The Alaska vein occurs one-half mile north of Pike. It strikes
east, outcropping for a distance of about one-half mile, and dips
north. The vein is of quartz, filling a fissure in diabase. The ore
once produced was very rich in coarse gold.

POKER FLAT MINING DISTRICT.

Including the region aboiit Poker Flat, Table Rock and Rowland Flat.

This district lies southeast of the Gibsonville district. Table Rock
is seventy-two miles by road northeast of Marysville; roads also
connect with Quincy, thirty miles to the north via Gibsonville, and
with Mohawk, twenty-seven miles to the northeast. Daily stages run
from Marysville and from Quincy when weather permits. In the
winter, when there is much snow and rain, the roads are in many

places impassable, but in the summer they are in fair condition tod
permit the use of motor trucks. Water is supplied by num[^H)ti«r
tributaries of Slate Creek and Canon Creek. Cheap electric po"V^er
may be obtained.

History of mining.

On the south slope of the ridge southeast of Table Rock a gravel
deposit, known as the California Diggings, has been hydraulicked.
On the south side of Canon Creek, opposite the California Diggings,
the Deadwood gravel deposit has been worked by both hydraulic and
drift mining. The gravel has been followed under the andesite eap
in a southeasterly direction to the Bunker Hill mine. The gravete
about Potosi and Howland Plat have been drifted along the ebamiel
under the lava.

The production of placer gold at Table Rock, along with that of
St. Louis in the adjoining Port Wine district, was $28,000 in 1905
and $26,700 in 1909.

Topography.

Table Rock and Mount Fillmore lie between Canon Creek and Slate
Creek, tributaries of the North Pork Yuba River. Table Rock, ele-
vation 6980', is a high peak on a ridge which extends southwestward
to Queen City and Port Wine. Canon Creek lies south of Table Rock
at an elevation of 4800'. In the Poker Flat region to the east andesite
forms a cap continuous with that on Table Rock and Mount Fillmore^
elevation 7816'. The north slope is drained by the East Branch of
Slate Creek. Rattlesnake Peak, elevation 7400', is on a ridge three
miles east of Poker Flat ; its north slope is characterized by irregular
spurs. The ridge south of Poker Flat is broad and flat, and purtially
covered with andesite ; it continues westward to Deadwood Peak.

The main drainage of the district has a general southwest direction ;
the streams are all tributaries of the North Fork Yuba River.

Geology.

Closely folded slates and quartzites compose most of the district.
They generally strike north and dip nearly vertically. In the extreme
southeastern portion of the district they strike northwest and dip
75° E. On the ridge east of Deadwood Peak the sediments have a
northeast strike.

Both north of Potosi and west of Poker Flat amphibolite occurs.
Northwest of Potosi it strikes northeast, and dips 70° SB.

18 MINES AND MINERAL RESOURCES.

About one and one-half miles west of Mount Fillmore a belt of
serpentine, about three-fourths mile wide, is in contact with amphib-
olite on the west, and with the Calaveras formation on the east. A
narrow belt of serpentine just east of Poker Plat extends in a north-
easterly direction; it is probably continuous, under the andesite cap,
with the northern belt.

One mile east of Poker Flat a body of augite-porphyrite one-fourth
mile wide and two miles long extends northward towards Mount
Fillmore. A small body of the same rock also occurs one-half mile
west of Poker Flat.

One mile northeast of Rattlesnake Peak a body of granite about
one-half mile in diameter intrudes the Calaveras formation. Its
northern border is covered by basalt.

Deadwood Peak is covered by an isolated body of andesite, which
itself is covered by a small body of basalt. A mile and a half north-
cast of Poker Flat a small area of andesite partly covers a narrow
area of rhvolite lava.

At some time in the Juratrias period there were flows of augitic
lavas and tuffs ; these were compressed with the Calaveras formation
and form the augite-porphyrite of the present time. The amphibolite
may have been formed in a similar manner, but it is likely that the
amphibolite and serpentine were intruded into the Calaveras forma-
tion at the end of the Juratrias period. Granite was probably
intruded about this time.

During the Tertiary period the region was eroded and auriferous
vein material accumulated in the river beds. Toward the end of
Neocene time rhyolite flows occurred, followed later by an extensive
flow of andesite, covering practically the entire region. Following
this an uplift occurred, which increased the rate of erosion.
Scattered basalt flows took place during the early part of the
Pleistocene epoch and a period of glaciation followed during the
middle part of the Pleistocene. One small area one mile northwest
of Rattlesnake Peak remains covered by glacial detritus.

Mineral deposits.

The only mineral deposit, at present of economic importance, is
gold which occurs in gravels of the Neocene river channels. Water-
worn pebbles of chrome-iron found in the gravel at Howland Flat
probably came from the serpentine area east of Gibsonville.
' The main Tertiary river channel west of the Neocene divide extends
from Port Wine and St. Louis through Howland Flat and Potosi,
disappearing at the latter place under the lavas of the Mount Fill-
more ridge. The channel has been followed through the ridge by
tunnels, reappearing on the south slope at Gold Canon. It is reported

SIERRA COUNTY. 19

that the channel rises towards the middle of the ridge and then falls
so that at Gold Canon the elevation is the same as at Howland Plat.
The rise and fall is by steps, the channel being suddenly cut off at
several points by polished and striated walls indicating faults. At
Howland Flat the gravel is well exposed and rests on a bedrock of
amphibolite ; to the south at Table Rock the channel is covered by
andesite.

The California Diggings are located on the south slope of Table
Rock, in a ravine draining into Caiion Creek. The bedrock is
amphibolite; the andesite of Table Rock partially covers the gravel
and separates the exposure from that at Howland Flat.

White quartz gravel occurs in the Deadwood channel, one mile
southwest of Poker Flat, on a bedrock of the Calaveras formation.
To the south the gravel is capped by andesite, under which the
channel has been followed for about a mile in a southeasterly direc-
tion to a claim known as the Bunker Hill. In the tunnel many faults
and numerous lava dikes have been encountered.

Auriferous gravel has been mined on the south slope of the lava-
capped Rattlesnake Peak ridge by drifting at the Red Oak property
and by hydraulicking at the Rattlesnake property. The gravel rests
on the Calaveras formation. Some drifting has been done in the
basalt-capped gravel lying on granite northeast of Rattlesnake Peak.

PORT WINE MINING DISTRICT.
Including the region about Port Wine, Queen City and St. Louis.

Port Wine is located close to the northwestern border of Sierra
County, sixty-five miles, by road, northeast of Marysville, a point on
the Southern Pacific Railroad. There is a mountain road from Port
Wine to Johnsville via Gibsonville, thence to Blairsden on the
Western Pacific Railroad, a distance of about thirty-five miles. The
roads are fair in the summer, but in many places impassable during
the winter, at which time there are heavy rains and snowfall. Port
Wine and Queen City lie at elevations of about 5000' above sea level.

The district is wooded with fir and spruce. Water is plentiful in
Caiion Creek, Little Canon Cl-eek, and the tributaries of Slate Creek
which flow through the district.

History of mining.

In 1897, at the Bunker Hill claim, not to be confused with the mine
of the same name further south in the Poverty Hill district, a tunnel
was run under the lava. At the Lucky Hill mine development work
has shown that gravel underlies portions of the andesite cap between
the Bunker Hill and the Iowa shaft to the south.

MINES AND MINERAL RESOURCES.

SIERRA COUNTY. 21

Most of the Tertiary channel has been mined from Port Wine
through Queen City, Grass Plat, Gardener's Point, Cedar Grove
Ravine and St. Louis to Howland Flat. In 1891 it was estimated
that on the Port Wine ridge 1,600,000 yards of gravel had been exca-
vated, while 5,000,000 cubic yards remained. The value of the placer
gold produced at Port Wine in 1905 was $3500, and in 1909, $1000.
The St. Louis property had a somewhat higher production.

Topography.

The district consists of two parallel divides, and a portion of a
third. These ridges, and the streams between, have a northeasterly
direction.

Port Wine and Queen City, one-half mile apart, lie between Canon
Creek and Slate Creek. West of these settlements the ground slopes
gently to Slate Creek, while to the east it rises to the top of the divide,
and then drops 1200' to Canon Creek.

A broad flat divide becoming a narrow ridge to the north, separates
Canon Creek from Little Canon Creek. Grass Flat is on the same
divide as Queen City. St. Louis is on the southwestern end of How-
land Plat, between Slate Creek and Cedar Grove Ravine.

Geology. .

A belt of the Calaveras formation extends in a northwest direction
through Port Wine and Queen City. It is in contact with amphibolite
both to the northeast and southwest ; Queen City lies near the north-
eastern contact. It consists of closely folded slates and quartzites,
which strike northwesterly and dip nearly vertically. Andesite
covers these formations on the ridge between Slate and Canon creeks.

A series of lenticular shaped bodies of augite-porphyrite arc
enclosed in the Calaveras formation and extend under the andesite
southeast of Queen City. It is composed of volcanic tuffs or lava
flows that have been folded in with the sediments and metamor-
phosed. The age of the formation of igneous rock which later was
changed to augite-porphyrite is probably Juratrias.

Amphibolite may have been formed in a manner similar to the
augite-porphyrite, but is possibly a metamorphosed diorite or gabbro.
Two miles northeast of Queen City the schistosity has a vertical dip
and an east-west strike. The amphibolite, if intrusive, is probably
post-Juratrias in age.

22 MINES AND MINERAL RESOURCES.

Auriferous gravel accumulated during the Neocene epoch. Toward
the end of this time an extensive flow of andesite occurred probably
covering the entirp region, and. later still an uplift increased the rate
of erosion ; most of the andesite was worn away but considerable
remains capping the interstream ridges.

Minaral deposits.

The only mineral deposit known at the present writing is placer
gold which occurs in the gravels of the Tertiary river channels.

The Port "Wine channel is a branch of the main Tertiary river
channel to the west of the Neocene divide (Sierra Buttes). The
gravel, in general, consists of well-washed white quartz pebbles lying
in a well-defined channel several hundred feet wide and 50' deep.
Heavy masses of pipe clay, occurring above the gravel, are often
covered by andesite tuff.

The Bunker Hill gravel, one-half mile southwest of Port Wine,
covers the contact between amphibolite and the Calaveras slates.
The bedrock at Port "Wine consists of the Calaveras formation. At
Queen City the bedrock is both Calaveras and amphibolite, while at
Grass Plat it is amphibolite. The deposits are al! partially covered
with andesite on the ridge to the southeast. The Lucky Hill drift
mine, between the Bunker Hill and the Iowa shaft to the south, proves

the continuity of the Tertiary channel, below the andesite cap,
between the latter two places.

At St. Louis, an extensive gravel deposit is exposed. There is only
one small area of andesite breccia capping the gravel in this region
and that lies to the east on a spur from Table Rock. The bedrock in
this region is amphibolite.

A deposit of gravel which occurs on the ridge between Canon
Creek and Little Canon Creek has been extensively mined. Good
exposures are seen at Morristown, two miles southeast of Port Wine,
and at Craig's Flat, one and one-fourth miles farther south. At
Craig's Plat the upper surface of the gravel appears to have been
eroded before it was covered by andesite breccia. These gravels are
probably on the same channel as the gravel at Eureka, in the Eureka
District, one and one-half miles southeast.

POVERTY HILL MINING DISTRICT.
Including Poverty Hill, Scales and Mount Pleasant.

This district includes large deposits of Tertiary auriferous river
gravels which have been developed along the main channel extending
from Hepsidam to Scales. No gold is obtained from the more recent
river gravels nor from quartz veins.

The district is located near the western boundary of Sierra County.
The elevation of Scales is 4300' above sea level. Marysville, on the
Southern Pacific Railroad, is fifty-nine miles by road to the south-
west. A very mountainous road runs from Scales northeast to Clio,
on the Western Pacific Railroad. The roads are in fair condition in
summer, but in many places impassable in winter, during which time
there is heavy snowfall and much rain. Water is plentiful. Several
lakes occur in the immediate vicinity of Scales. Canon Creek, with
numerous short tributaries, flows through the district. In the north
are Slate Creek and its tributaries. Cheap electric power is available.

History of mining.

Hydraulic mining has been carried on at the Sailor Boy and the
Fairplay mines and at McMahons, Scales and Poverty Hill. The
gravels have been drifted at the Lucky Hill, Iowa and Bunker Hill
properties. The Poverty Hill District produced $11,000 in placer
gold in 1905, but only $6800 in 1909.

24 MINES AND MINERAL RESOURCES.

Topography.

The region consists of the southeastern portion of the elevated area
between Slate Creek to the north and Canon Creek to the south, and
also of the broad ridge south of Canon Creek.

Poverty Hill is on a southern tributary of Slate Creek. Mount
Pleasant lies at an elevation of 4500', two miles southeast of Poverty
Hill. At the base of the gently sloping south side of Mount Pleasant,
Scales is located on a nearly level area a mile and a half southwest of
the summit. Southeast of Scales the ground slopes towards Caiion
Creek.

Geology.

The chief formation in the southern part of the district is the Cala-
veras, consisting of closely folded slate and quartzite. It is con-
tinuous with the same formation in the Indian Hill District to the
south.

In the eastern part of the district are belts of serpentine and
amphibolite. The amphibolite inert fuses in. width to the northwest
and is covered by flows of andesite on the ridges east of Poverty Hill
and south of Caiion Creek. A lonj?, narrow cap of andesite extends
along the rim of the canon southeast of Scales. A small intrusive
body of granodiorite underlies the Tertiary gravels at Scales and is
in contact with the Calaveras formation to the southwest.

In Rock Creek, one-fourth mile southwest of Scales, dikes of white
quartz-porphyry cut the Calaveras formation. The rock has a fine
grained ground mass of quartz and feldspar, with phenocrysts of
feldspar, biotite, hornblende and quartz. These dikes may be geneti-
cally related to the granodiorite.

The region was eroded during the Neocene epoch and the auriferous
gravels were deposited, the gold probably being derived from eroded
quartz veins.

Mineral deposits.

Gold is the only mineral of economic value in the region. It occurs
as small particles of various sizes in Tertiary gravels which are
generally richest where the rivers crossed the auriferous slate belts.
In 1891 it was estimated that at Scales and Mount Pleasant 4,050,000
cubic yards, and at Poverty Hill 2,250,000 cubic yards, of gravel had
been removed. The amounts still available at these places have been
estimated at 60,000,000 and 5,000,000 cubic yards, respectively.

One of the main channels of the Tertiary river systems ran from
Scales southward through Indian Hill to Camptonville. North of
Scales the channel forked, one branch extending through Poverty

SIERRA COUNTT. 25

Hill, La Porte and Hepsidain, the other through Mount Pleasant, dis-
appearing under the lava and reappearing at Bunker Hill, Port Wine
and Potosi.

The main gravel channel has an average grade of 100' to the mile
taken as far south as- Camptonville. The lowest grade, 60' to the
mile, occurs between Poverty Hill and Scales; there the channel has
a general soiithi'rly direction, and is filled with quartz gravel to a
depth of 120'. The bedrock is granodiorite and the Calaveras forma-

tion. Prom Poverty Hill the channel extends through Secret
Diggings to La Porte.

The smaller Port "Wine branch is almost parallel to the main
channel, lyin^ only from two to three miles east of it. The channel
is several hundred feet wide and has well-defined rims of amphibolite
rising several hundred feet above the bottom. The quartz gravel,
iibout 50' deep, is overlain by heavy masses of pipe clay, which is
covered by andesite tuff or basalt.

The Iowa shaft was sunk through cemented gravel at a point nearly
three miles, by road, northeast from Scales. The elevation of the
collar of the shaft is 4900', while that of the lowest bedrock found
exposed is 4582'. The mine was worked about thirty years ago and
it is reported that $30,000 worth of gold was recovered.

A small amount of hydraulic mining has been done at the Sailor
Boy property two miles east- south east of Scales; drift mining has
been carried on at the Biinker Hill property two miles southeast of

26 MINES AND MINERAL RESOURCES.

Scales. At both places the gravel rests on a bedrock of the Calaveras
formation and is composed of pebbles of dark quartzite, siliceous
schist and Tertiary lavas. At McMahons, two and one-half miles
east of Scales, the gravel rests on amphibolite; the pebbles in the
lowest gravels are composed of white quartz; High bedrock inter-
venes between these gravels and those at Eureka.

SIERRA CITY MINING DISTRICT.
Including the region around Sierra Buttes, Furnier and Church Meadows.

This district includes some of the most profitable quartz mines in
the entire Downieville quadrangle. There are only a few deposits
of auriferous Tertiary gravel within the district, but recent gold
bearing gravels occur along the North Fork Yuba River.

Sierra City is situated in the south-central portion of Sierra County,
twelve miles by road east of Downieville along the North Fork Yuba
River. The distance by road from Nevada City is fifty-six miles via
North San Juan and Camptonville. A road connects with Loyalton,
thirty-six miles northeasterly, and with Marysville, county seat of
Yuba County, eighty miles to the southwest. A daily autostage
makes the twenty-mile run between Sierra City and Blairsden, a
town on the Western Pacific Railroad, between the months of June
and December. The region about Sierra City has warm summers,
but the winters bring heavy rainfall and snow. An abundance of
water is supplied by the North Yuba River with its many tributaries
and by many glacial lakes which occur in the eastern part of the
country.

History of mining.

The only mineral product of present economic importance is gold.
Many lenses of magnesian limestone occur to the west and north of
Sierra City, and there are masses of magnetite in the extreme
northern part of the district.

The placer gold deposits along the North Fork Yuba River were
worked long ago and produced much gold.

The gold quartz veins have been worked with profit for many years
but are now undergoing a period of depression. The largest of these
veins are found at the Sierra Buttes, the Young America, the Moun-
tain mine and the Phoenix mine.

MINES AND MINERAL RESOURCES.

Topography.

The district is very rugged and mountainous. Sierra City is in the
narrow valley of the North Fork Yuba River at an elevation of 4300'.
It lies at the southern base of the Sierra Buttes, which rise to an
elevation of 8615' in a distance of two miles. To the south the region
rises abruptly from the river to a flat-topped ridge, 2500' above the
river.

CHROMITE.*

Case and VLjer Property. Owners, Case and Myer, Downieville.
Leased to Bynon and McGonigal, Downieville. Comprises seven loca-
tions and 90 acres of patented land, a total of 230 acres, situated
thirty-five miles from Rlairsden.

Pipes of chromite in serpentine have been developed by an open
cut, shaft and stopes. In July, 1918, nine men were employed. The
property had produced four carloads of ore at that time and was
thought capable of yielding perhaps six carloads more. The ore was
said to average about 45% CrgOg. It was hauled a mile in wagons,
one-half mile in an aerial tram and thirty-three miles in autotrucks
to Blairsden on the Western Pacific Railroad. The hauling season
lasts from June 1 to the first rains in autumn.

Dorriff IBne. Owners, Dorris, Davis, Bradbury and Dobbie, all of
Forest. Leased to Morgan and Leichester of Nevada City. Includes
five unpatented locations, 100 acres, near Forest and thirty-three miles
by road from Nevada City.

Small lenses of chromite have been mined by shallow shafts and an
open cut. The production to the end of July, 1918, was a small car-
load with possibly 15 tons of ore still in sight. Hauling to Nevada
City in autotrucks cost $15 a ton.

EvaBs Prospect. Owner, Robert Evans, Forest. Four tons of
chromite taken from a small 'shaft was shipped in July, 1918, and
there was said to be no more ore in sight at that time. The claim
is near the Dorris mine.

Fiaane Prospect. Owner, Steven Finane, Forest. This claim,
located near the Dorris mine, produced 8 tons of 45% chromite ore up
to August 1, 1918, and showed no promise at that time of further
production.

Macchaus Mine. Owners, Macchaus, Redmayne, McGonigal and
Finane, of Alleghany. Located twenty-nine miles from Nevada City,
near Alleghany. The property consists of 3 unpatented claims
covering an area of about 60 acres.

This mine yielded a little over 200 tons of chromite, said to average
46% CrgOg, from lenses containing 15 to 20 tons each which were
mined by open cuts. The property was reported worked out and
abandoned August 1, 1919.

•Note. — For the following data on chromite properties in Sierra County, we are
Indebted to the United States Bureau of Mines for the use of field notes taken by
Harry Thompson.

30 MINES AND MINERAL RESOURCES.

Redmayne and McOonigal Prospect. Owners, Geo. Bedmayne and
D. McGonigal.

This property, located four and one-half miles from Sierra City,
showed about 25 tons of float ore said to carry 30% CrgOg, which was
too low grade to be profitably handled, considering the long haul to
the railroad.

White Bear Mine. Owner, John Costa, Downieville. Leased to
Ostrom Brothers and Lindvall Brothers, Downieville. Comprises 5
placer locations situated seven miles from Downieville and forty miles
from Blairsden.

The four lessees worked the property during the summer of 1918,
and produced about 250 tons of ore containing 40% to 45% CtjOs.
The ore was taken .on pack animals one-half mile, then loaded on
trucks which hauled it to Blairsden. The total cost of hauling was
$20 a ton. The claims are on a steep mountain-side where the outcrop
was poor, and it was hard to estimate future production. Work
stopped in September, 1918, on account of rain.

This property has a total area of 441.02 acres and consists of the
Bald Mountain, Parkman and Oregon Creek Tailings claims, covering
a length along the channel of 5000'. The surface is lava capped and
covered with manzanita brush.

It was discovered in 1869 by a shaft 268' deep. A bedrock tunnel
1800' was run to this point in two years. The cost of putting the
property on a paying basis, in 1872, was $20,000. From that time
until 1887 the total production was $3,100,000; the net profit,
$1,300,000, was divided among 20 stockholders. The death of H. W.
Wallis, manager and superintendent in 1887, was followed by the
closing down of the mine. A consolidation of the Bald Mountain, the
Bald Mountain Extension and the Ruby properties, covering an area
of abotit 1500 acres, was brought about by Mark N. Ailing, of Downie-
ville. He, with the assistance of W. F. Coperland of Alameda,
organized a development company to reopen these mines. Work was
begun in July, 1914.

32 MINES AND MINERAL RESOURCES.

The higher ehamiel, the * Great Blue Lead/ was about worked out
and the pillars nearly drawn, when an incline was put down on the
contact of the bedrock and the lava filling of a deeper channel, which
found the channel to be 62' deeper than the higher lead and to contain
rich gravel. A break 400' long in the bottom of this deeper lead at
this point was worked and $60,000 is said to have been extracted.
This deeper channel was again tested by a shaft 400' soutli of this
point.

The property covers two ancient channels, the * Great Blue Lead*
(now worked out), being the older and the higher, and the 'Deep
Bald Mountain Channel,' an intervolcanic channel of the andesitic
period. The older channel was worked to the Ruby mine line, where
the lava filling of the newer channel cut off the pay gravel almost
exactly on the boundary line. This channel comes in from the Ruby
claim, crosses the 'Blue Lead' diagonally with a southwest course at
the north end of the Bald Mountain ground, courses south along the
west side of the 'Blue Lead' in close association with the same,
encroaching on the higher lead, more or less, for 3900', when it again
crosses the 'Blue Lead '"just below the point of confluence of the Bald
Mountain Extension tributary with the 'Blue Lead,' there cutting
away several hundred feet of the higher channel. The Ruby Com-
pany discovered this same deep lead and worked the west benches
of it for about 1000' to the Bald Mountain line. Except for 400',
the 'Deep Channel' has not been worked from the Ruby line to the
south line of the Bald Mountain property. Calaveras slates and
amphibolite schists with long parallel lenses of serpentine make up
the country rock. Rich quartz ledges occur in the schists and slates
along the contacts. Erosion of these by ancient rivers and tributaries
accounts for the richness of the ancient channels. The pay gravel
ranged from 300' to 600' in width and from 10' to 50' in depth. The
gravel was all quartz and quartzites, medium sized to fine; bedrock
mostly slate (Calaveras), soft and a good gold catcher. The gold
was mostly coarse, nuggets ranging from 1 to 20 ounces being
common, with some pieces weighing as much as 73 ounces, though fine
gold was also found. Black sands and arsenical sulphides were
common. Several quartz ledges were found in the mine, one with
free gold in place in the rock; the gravel below where the channel
had crossed the ledge was cemented together with sulphides.

In the southern portion of the Ruby ground the 'Deep Bald Moun-
tain Channel' cuts diagonally across and down through the 'Blue
Lead,' eroding away about one-half mile of original channel and
I'econcentrating. This channel was profitably worked by the Ruby
Company downstream to their boundary line 3900' further south.
The Bald Mountain Company sank an incline into this channel, the

SIERRA COUNTY. 33

gravel being practically all quartz, free and rich in gold. Four
hundred feet further south a shaft was sunk into this channel and.
rich quartz gravel 7' thick was found. About 3200' further south the
South Fork Company crossed this channel and found the gravel prac-
tically all quartz, aud carrying about 50ff per ton car in gold. It
appears that the bulk of the gold contained in the *Deep Lead/ and
derived principally from the erosion of the higher channel, lies on
the Bald Mountain ground. On this assumption it is estimated that
this deep channel will pay to work throughout the entire 5000'
channel in the Bald Mountain claim.

(October 2, 1915.) A shaft is being sunk to tap the north extension
of the Bald Mountain channel and is down 80'. Anottier shaft is
being sunk to develop a quartz ledge encountered in tunnel workings.
The Bald Mountain tunnel is being repaired and placed in shape for
C'perations.

Since Report XIII of the State Mineralogist (1896), the channel
has been worked about 1000' northward from where the tunnel struck
the channel. It was here cut off by lava, which fills the depression
of some secondary channel. After spending much money and more
than a year's time in searching for the continuation of the pay lead,
the mine was closed down.

In working south, or downstream, the pay channel was followed to
within 300' of the face of the old workings, extending into the moun-
tain from Forest City. Here the pay was cut off by lava, resulting in
the abandonment of this portion of the mine, including the tunnel
one and one-fourth miles in length, run from the headwaters of
Kanaka Creek, about three miles easterly from Forest City, through
which the above work was done.

It is thought that about one-half mile of virgin channel still lies in
the northern portion of the property. Extensive surveys were made
in 1914 to ascertain the position of this segment.

A large, deep, unprospeeted channel also extends through the
property from north to south along the western boundary, the eastern
tributaries of which are probably responsible for the erosion of the
higher channel at the various intervals where it has been cut away.

The Bald Mountain mine adjoins on the west.

This property consists of from 1000 to 1600 acres of patented
ground, including the Yuba, Gallant, Stanislaus, San Joaquin, Sacra-
mento, Merced, Columbia, and Wolf Creek claims, covering a length
along the channel of five miles.

The deposit consists of old channel gravels, coursing north and
capped with lava. The gravel is quartz and granite with some big
boulders on a bedrock of slate, porphyry and granite. It varies from
4' to 5' in depth and has a width of 600'. It has been worked for
the past 10 or 12 years only during the winter and spring on account
of shortage of water, which is obtained from Wolf Cre^k and from
the tunnel.

There are 5000' of tunnels, drifts and raises. The main tunnel,
3500' long, has exposed over 600' of gravel. The amount of gravel
worked could not be determined.

Equipment consists of a boarding house, blacksmith shop and tools.

This property consists of seven claims of 160 acres each, namely,
Gibraltar, Germania, Eclipse, Eclipse Extension, Divide, Gibraltar
Extension and Germania Extension. The aggregate of 1120 acres
covers a length along the channel of two miles. There is a good stand
of fir timber suitable for mine timber, fuel, etc., on the ground. The
property was first located in 1881 by Fritz Trimphin,. who ran a 600'
tunnel. The present company was reincorporated in 1893. Two men
were working in the summer of 1914.

The deposit is made up of old. river channel gravels, blue quartz on
soft slate bedrock with andesite capping. The gravel courses west
and varies from 2^' to 5' in depth. There is not much water in the
channel.

Development consists of a 1780' tunnel, 80' too high, several
upraises between the 900' point and the face of tunnel, a 310' shaft
sunk to bedrock, 400' from the face of tunnel, and a 35' drift in bed-
rock at the 296' point. All pay gravel taken from the shaft. No
breasting has been done. The main channel is supposed to be east of
the shaft, or in other words, the shaft struck a high reef of bedrock.

There is an 8-h.p. gasoline hoist on the property and a sawmill
is under construction.

40 MINES AND MINERAL RESOURCES.

This property has been located several times. It was last owned
by Chas. Hendel under the name of the Lucky Hill, until relocated by
the present owner in 1913.

The deposit is made up of quartz gravel of the Port Wine channel.
Its course is southwest and it is from 60' to 80' in depth, lying on a
bedrock of schist, and capped with 500' of andesite.

A shaft is to be sunk 300' through lava on the Gold Hill claim
farthest north.

Adjoining mines are the Iowa on the southwest, the Mountain Boy
on the north and the Bonton, Bella Union and Hardscriabble on
the east.

This property consists of located land aggregating about 700 acres,
of which 140 acres are patented. There is good timber on the ground
for mining purposes.

The mine was formerly leased to and operated by Chinese, wko
made good pay, but in 1910 it was sold to the state. The present
company was organized and it was reopened in July, 1914. A
deposit of gravel extending the full length of the claim was over-
looked by the Chinese. About 1000' of the channel has been worked,
producing in the neighborhood of $1,000,000.

Development work consists of a number of long crosscut tunnels
and drifts, the present crosscut working tunnel being 1800' in length
to where it cuts and bottoms the channel. This tunnel intersects the
channel near the western end of the property, so that the gravel is
extracted by working upgrade on the stream, thereby draining itself.
A number of long drifts have been extended into the ehannel from
the main working tunnel and an immense quantity of gravel has been
opened up. The upper tunnel, designed to ventilate the mine, is
1200' long. It will have to be continued 180' in order to connect with
the east drift, thereby giving the required ventilation to the whole
mine. .

The channel system passing through the Gold Star is part of the
Blue Lead of the Neocene period, and is known as the Narry Red,
Young America, or Gold Star, and Cortoma and Slattery chani^l^
from the names of nearby mines. The trend is southeasterly, south-
erly and southwesterly. The channel is from 150' t6 200' in width
and from 4' to 10' in depth, and is capped with a large deposit of

SIERRA CJOUNTY. 41

vol^a»ic lava. Portions of the gravel are uncemented and free-
washing, while other portions are cemented. Samples show from $3
to $7 per ton. This channel has been worked in the Young America
and Cortoma properties when it ran from $5 to $10 per car. To the
west, in the Omega and Slattery properties the values proved equally
B£B good. At present there is a breast of gravel 250' in length across
tli« drift, and from 4' to 10' in depth. This can be worked as soon
as the drift is put in proper working condition. There is a reserve of
ahotrt 4600' of channel in this ground.

A number of quartz veins having the general characteristics of
veins m the Alleghany District are found on the property, in a broad
belt or finger of serpentine which runs northwesterly and south-
easterly through its center. East of the serpentine is amphibolite,
to the west is slate, and the Oriental vein is on the amphibolite-
serpentine contact. The Oriental mine has produced $3,000,000, one
btinch of (yte containing $740,000. That portion of the Oriental veins
which i& in the Gold Star ground should be developed, as there are
in^eatioiis that it would probably be a large producer. On the slate
and serpentine contact is a continuation of the vein found on the Kate
Hardy property to the north. This property has produced large
amounts of specimen ore.

The mine is equipped with several trains of gravel cars, blacksmith
shop, complete set of tools, and outbuildings. There are a number
of long flumes for washing the gravel, but these are out of repair.

Water can be obtained free the year round from a ravine situated
about 2000' west of the mouth of the working tunnel. It will be
necessary to construct a 4" pipe line from the mouth of the tunnel to
the ravine in order to give ample water for all requirements. Mining
is done principally with pick and shovel, powder being used only
occasionally to loosen the ground. The channels are overlain by a
cemedted sand whi^h makes a splendid roof, requiring but little
timbering and the cost of mining the gravel should not exceed $1 per
ton. One miner can produce from 4 to 6 cars of gravel per shift and
is paid at the rate of $3 for 8 hours work.

The Kate Hardy property adjoins on the north, the Oriental on the
southeast, the Young America on the east, the Cortoma on the north-
east and the Omega and Slattery properties on the west.

The Iowa property embraces 400 acres patented, including the
Iowa, Manhattan, Centennial, and Iowa Tailings mine. Besides this,
Harris owns the Black Bear location (139.14 acres). Quartz Hill,
patented (39.98 acres), and Canada (Empire) location (300 acres,
mostly worked out to Port Wine). The property is situated on the
flat south of Lone Tree and Bald Mountain and contains good timber.

The deposit is an old Neocene channel coursing north on schist
bedrock and capped with andesite.

It was located in the early 70 's. Bought by Harris and others in
1876 and worked by them until 1879. The property is credited with
a total output of $85,000.

The channel is developed by a shaft 300' deep, a 600' incline and a
drift 400' to the north, also a 6000' drain tunnel. The shaft is sunk
100' through lava. In the 400' drift to the north, in the last work-
ings, a rim is said to be dipping steeply to the northwest and it is
claimed that the channel lies west of the workings and that all the
workings are in a breakover from the main channel. A 3000' tunnel
is to be driven from the ravine on Canon Creek.

There are no records of the amount of gravel worked, but it is said
that it averaged $1.75 to $2 per car, and that one man could take out
10 ears per day.

The Kanaka drift mine consists of the Kanaka Nos. 1 and 2, whicli
cover the 'Kanaka Blue Lead' channel for about 4000', and the
Kanaka Nos. 4 and 5, which cover about 4000' of the * Kanaka White
Lead' channel, a south extension of the 'Mount House drift mine'
channel. Claim No. 5 embraces a portion of the old Unmedico claims.
There is a total area of about 600 acres of unpatented ground. Claims
Nos. 1 and 2 include 'Long Point,' a lava-capped ridge extending in
a southerly direction. Nos. 4 and 5 extend south across a lava-capped
ridge covered with thick manzanita brush on top and yellow pine,
spruce, fir, cedar and oak timber on the sides.

Tunnel work was prosecuted in a small way by Dr. Eraser of San
Jose from 1900 to 1911 on the old Unmedico claims with the aim of
tapping the 'White Lead.' The claims were abandoned on his death
and relocated in 1912 by the present owners. The property was
being developed by Arthur Fritsche of Berkeley, who had the mine
under lease and- option to purchase in 1915. Operations began
October 7, 1914, and a small crew of men were to be employed during
the winter.

The 'White Lead' is a channel from 200' to 400' in width, filled
with white quartz gravel from 3' to 10' in thickness. A thick layer
of pipe clay lies over this with andesitic lava tuffs, mud and breccia
on top, capped in turn with basaltic lava cemented mud. This
channel courses south. The 'Kanaka Blue Lead' lies at such a level
and courses in such a direction that it is thought to have been a
tributary to the 'White Lead.' The gravel is fairly coarse but not
big and the gold is free. Soft Calaveras schists and slates form the
bedrock of the channel, which follows along close to the east contact
of the west belt of serpentine in the Calaveras rocks.

A lower tunnel (No. 1) 500' in length, extends in a northeasterly
direction from the west branch of Blue Ravine. It begins in ser-
pentine and strikes slate at the face. Two raises disclosed pay
gravel, but not in place, and the channel proper is thought to lie
about 600' further in the hill in the Calaveras formation. This tunnel
is about 80' lower than the channel proper, and another tunnel was

for 430'. Nothing but serpentine was found as it did not extend to
the contact. Prospect shafts are now being sunk on the surface
preparatory to running a bedrock tunnel to the main channel. The
gravels are to be treated in revolving trommels before running
through sluices, owing to gold being carried away on the unwashed
rocks.

In 1914 there was only prospecting equipment on the ground.
Water is obtained from Blue Ravine and local springs. The Yuba
Hydroelectric Company's power line crosses the property near its
center.

Operations were resumed on this property in August, 1915.
Development consists of two shafts and drifts, but it was decided to
drive a crosscut tunnel to tap the channel at depth. Snowsheds
erected early in the winter of 1915-1916 permitted continuous work,
and the drift had been run 240' by March. It will be extended 100'
further to tap the channel. Eight men were employed and more
were to be added with the opening of spring. The nearby Alleghany
mine is to be operated by the same interests.

46 MINES AND MINERAL RESOURCES.

The Lost River mine consists of the following claims: the Lost
Kiver Nos. 1, 2, 3, 4, and the Tailings claim, a total of 700 acres,
covering about two miles of channel. It is situated on lava-capped
tableland, heavily timbered on the slopes and covered with dense
manzanita. The Bunker Hill contains 640 acres, covering a length
along the channel of two miles, making a total of four miles.

The property was discovered about 1880 and James Arnott, Sr.,
organized a company known as the Rocky Peak Mining Company,
and two main tunnels were run. Owing to exhaustion of funds, the
company ceased operations about 1895, finally abandoning the prop-
erty about nine years later. In 1904 it was relocated, but after
failing to organize a development company it was again abandoned.
In 1911 the property was again located by Mark N. Ailing and others,
and in 1913 Norton E. Wilcox of Berkeley and Paul W. Smith of
Downieville took the property under lease and option to purchase.
During the summer of 1914 they put down ten drill holes locating
the channel. Two shifts of two men each and three men cutting
M'^ood were employed. The Bunker Hill was discovered in 1875.
Five men were at work in 1914 running a 325' tunnel, 6' by 5' in
the clear.

The Rocky Peak Mining Company ran a tunnel in a northwesterly
course for 700' or 800', and some pay gravel was found a short
distance from the mouth on what was thought to be a bench. The
tunnel, which started in slate bedrock, soon ran into lava, filling the
trough of an ancient river. At the face a shaft was sunk 90' in lava,
but a heavy flow of water forced the abandonment of this attempt.
The company then moved down to Monterey Ravine and ran a tunnel
under a big surface slide. This Monterey tunnel is from 700' to 800'
in length, begins in slate bedrock and runs N. 70° W. (magnetic) into
hard fine sand and granular *pipe clay.' No channel in place was
found. Wilcox and Smith have recently used a No. 3 Keystone
churn drill, and located both rims and the approximate position of
the deepest poHion of the channel. The average depth of the holes
is 155'. Gravel was found in six of them, there being as much as
10' in some. Pay gravel was struck in the tenth hole, about 600'
west of the NW. J of Sec. 4. The gold is small and well rounded.
A tunnel to develop and drain the mine was to be started in the spring
of 1915.

The channel appears to be of good size, ranging in width from 200'
to 400', with gravel composed of quartz and quartzite rocks, but no
lava pebbles. It is free and contains medium sized boulders on the
bedrock of hard, siliceous black slate. Several feet of granular pipe
clay immediately overlies the gravel, above which comes andesites
and basalt. The channel courses about due south, or a little to the

west of south, and this channel is thought to be a southern extension
of some of those worked in the Port Wine Ridge.

About three miner's inches of water was developed by the old
Monterey tunnel.

The Lucky Dog property consists of one claim, with an area of 150
acres covering a length along the channel of 400'. It is a relocated
claim and assessment work only has been done in the last ten years.

The deposit consists of old channel gravels, mostly lava, but with
some quartz, lying on porphyry bedrock and capped with lava. The
channel courses north and the pay gravel has a depth of 4'. .

The ground has been developed by a tunnel through hard rock and
1300' in the channel. Some water was encountered.

There is a cabin on the property.

U. S. Geol. Survey Folio 66, Colfax.

The Mabel Mertz property consists of five locations, a total of 495
acres, covering a length of 6000'. It is situated on a lava-capped
ridge near the headwaters of Kanaka Creek, and has a good stand of
timber.

The property was located July 7, 1895, by the present company and
has been worked at intervals for the last 16 years, producing to date
about $2000. It was shut down in May, 1914, but was to be worked
by two men during the winter.

There is a total of about 8000' of tunnels, drifts and raises. The
lower is 2700' long; the upper tunnel, 92' above, is 800' long. The
tunnels are driven through shale and porphyry, most of the work
having been done in the fault zone in the northern part of the channel.

The gravels are the same as those in the Emigrant channel of the
Nebraska mine. They course south on a bedrock of slate and are
capped with andesite.

The northern part is said by Ailing to have been raised 105' with
a throw to the west of 250'.

Considerable water encountered.

and estimated to carry a stand of about 300,000' of pine and cedar.
Three men were working in 1914 driving a tunnel.

A blacksmith shop and cars make up the equipment.

The deposit is made up of old channel gravels, mostly red, on a
bedrock of slate. The gravel is 30' deep, and the capping of andesite
averages 50' in width and 4' in depth.

The west channel was struck by a 1600' tunnel and shaft. Water
was encountered. A tunnel which will have to be 1500' long, was
being run 100' lower. An area 50' by 1500' has been worked.

The Miner's Home mine comprises five claims and a tailings claim,
namely, the Kewana, North Kewana, Union, Hibernia, Shirley, and
Creek tailings claim, a total of 155 acres, covering a length along the
channels of from 3000' to 4000'. It is situated on the rolling ground
at the base of Table Rock.

The lower channel was worked out by the Union and Hawkeye
companies during the early days by drifting. It is said to have
averaged 60^ per square foot of bedrock. In the Hawkeye 66,506
square feet of bedrock yielded a gross return of $77,000, or $1.16 per
square foot. When, work stopped, gravel was running $7.75 per
18 cubic foot car. This region has produced in the neighborhood of
$14,000,000.

The main tunnel, 6' by 6' in cross section, is 3170' long. It is
called the Talk tunnel and is driven on the north rim 1800' (40' below
the old Hawkeye tunnel), then a raise of 12' and the tunnel continues
'J 50' in old gravel and clay, then a raise of 33' into the north rim of
the upper channel, in which it continues 500' farther east. A few
laterals have been driven into the gravel, but very little breasting
has been done. A drift across the channel would be advisable to see
whether the pay gravel and clay will be found across the whole width
as developed in the lower channel.

The deposit is an intervolcanic channel lying on rhyolite tuflf, etc,
The channel courses southwest with a big swing to the south between
the Hawkeye and the end of the property. The gold is found in a
so-called blue clay which is evidently a fine ash containing large
boulders of white quartz, well rounded and waterworn, together with
fine wash gravel, and it is said to be coarser than that which was
taken out of the lower channel, ranging in size from fine to pieces as
large as a dime. It appears that the old channel was first covered by
the rhyolitic deposit and later, at the time of the deposition of the
blue ash, there was a break above and the gold and old channel gravel
was washed down onto the rhyolitic bedrock. The blue clay disin-
tegrates in the water. In the upper channel there is said to be 6000
square feet of bedrock blocked out which will average $1.06 per
square foot and 230,000 square feet practically proven. The width of
the channel is reported to have been 500' and the upper channel was
worked to a considerable width in the Hawkeye claim by Overstreet

at a large profit. The lower gravel is stated to have been 5' to 10' in
thickness, above which was the rhyolitic tuff, then came 1' to 2' of
pay gravel mixed with 'blue clay' and from 25' to 109' of fine wash
gravel capped by andesite.

Equipment consists of a washhouse, blacksmith shop, 10 cars (18
cubic foot) and all tools for 20 men. Water through a 10" pipe
under 60' head is purchased from the Water Company at $250 per
year. Labor costs $3.25 to $4 per day. Freight from Marysville to
mine is 1^^ per lb. There is no timber on the property and lagging,
delivered costs $6 per M.

At the Hawkeye mine, adjoining, considerable gravel was worked
during the summer of 1915 with good results. Snowsheds were built
so work can be continued throughout winter.

The Monte Carlo mine was being operated in the summer of 1915,
yielding nuggets worth $3 to $4 each. The pay continues to increase

the channel of 3000'.

The Morristown property was purchased by Harris in 1885,
hydraulicked in 1888, and closed down in 1890.

The deposit consists of old channel gravels 75' deep, 200' wide and
capped with andesite, coursing north. The gravel is free, contains
some quartz boulders and lies on slate bedrock. There is said to be
400 acres that could be hydraulicked; $7000 was taken out in one
short season with water obtained from Little Grizzly Creek. There
is a 3-mile ditch which delivers 2500 inches under 125' head for 4J
months out of the year.

Must be drifted on back channel to work.

The Mountain House property consists of eight claims, the Moun-
tain Nos. 1 to 8, inclusive, discovered and located in 1911, 1912, 1913.
It covers a length along the channel of 13,000'. The surface is
characterized by a high lava-capped ridge covered with brush and
timber, with good loam in the flats and on the northern slopes.

A discovery tunnel, about. 700' long in the gravel, is supposed to be
following down stream, but no grade in the channel was found
beyond the first 75', indicating that the deposit discovered is either a
bench or a flat place of unusual length. Lava, with considerable
water, was encountered in this tunnel, so a tunnel 40' lower was run
400' and the same lava encountered again, indicating that a second
and deeper channel has cut through the original or else that the main
channel is lower than any of the workings. No breasting has been
done except for testing purposes. The main tunnel has been run
along the center of the deposit, laterals being extended to the
supposed rims on either side.

The channel courses due south on Calaveras formation between
serpentine bodies throughout the property. The gravel is quartz,
ranging from 2' to 6' in thickness, nearly every pebble of which is
white. It is about 200' wide and is capped by about 22' of pipe clay,
overlaid with several hundred feet of andesite tuff, mud and breccia,
covered in turn with basalt. The gravel is free and the gold assays
946 fine.

Where the channel had grade, it was prospected for a width of
cbout 65', an occasional pan being found yielding as much as 50ff.

52 MINES AND MINERAL RESOURCES.

Where the lava was encountered at the end of about 600' of dead
level deposit, the gravel carried very little gold. This channel is
thought to be the south extension of the White Bear channel. A 9'
quartz ledge follows the contact along the west side of the Calaveras
formation.

Equipment consists of 2 iron cars, 10 cubic foot capacity, 8- and
12-lb. T-rails, 7" galvanized air pipe and blower rim by gasoline engine,
washing floor 16' by 20', dwelling houses and a blacksmith shop at
the mouth of each tunnel. Water supply from local springs has been
developed.

Timbers, spruce and fir, cost only $1 per set, as plenty of timber is
standing on the ground. Five men were employed, wages being $2.50
per day, with board, in 1914.

At present, the gravel is washed in a small sampling wash yard
and run through a short string of boxes with pole and Hungarian
riffles, the tailings being dumped into a ravine.

Pleasant View Mine. Comprises the Pleasant View No. 1 and No. 2
(formerly called the Jackson and Roman) and the Flatiron claims,
covering 220 acres, with 2250' of channel still said to be unworked.
The property is on Oregon Creek three miles from Camptonville, and
thirty miles from Nevada City by wagon road. It is owned by E, E.
Brownell, II. N. Stetson and Julia C. Wyncoop, and is leased, with
option to purchase, to 0. D. Woodman of Camptonville and Nevada
City.

The deposit is in a deep channel and has been worked by tunnel
200' below the surface. In the fall of 1918 the tunnel was 1635' long,
and a total length of 900' of channel had been mined. The bedrock
is slate, the capping pipe clay, and the pay gravel is said to be 65'
wide. Five feet of gravel and 10 inches of bedrock are mined.

SIEBEA COUNTY.. 55

Woodman reports a total operating cost of $1.50 a ton. Shallow
flat holes are driven by hand and are shot with one-half a stick of
dynamite. Round pine and fir timber is used. Gravel is washed in
a line of sluices 175' long, but the gold is coarse and most of it is
caught in the first 20'. Marion Creek furnishes enough water for ten
months work. Tailings are restrained by a dam, and a new dam 10'
high was planned. The present operator began work in December,
1916. He planned to employ five men in the winter of 1918-19.
Miners are paid $3 a day and board. The total production of the
property to date is said to have reached $100,000.

This property consists of two claims, the Lassiat and Bettinger, a
total of 120 acres with a length along the deposit of 2000'. The sur»
face is flat.

In early days it was worked as a hydraulic mine, but was relocated
by the present owners in 1908. Six men were employed at $4 per day
in 1911

The channel has been developed by a 505' vertical 2-compartment
shaft, 4' by 8'. The west rim was struck at 505' and an incline at
45' was run following the rim for 300', but gravel has not been
encountered as yet. The channel is an old Neocene channel coursing

the locatiou of the channel and determination of its width and depth,
a long paain tunnel will be driven to develop the holdings. Pre-
liminary surveys indicate it will be necessary to extend the tunnel

The Ruby property consists of the patented Guatemala and Guate-
mala Extension claims, 440 acres, and the Garnet placer (20 acres),
arid Rock Creek tailings locations, covering in all about 3000' of the
creek.

In 1856 an ancient channel was discovered by a shaft sunk on the
bank of Rock Creek at the north end of the Ruby claims, and the
gravel was worked for years. The property was purchased in 1871
by the Ruby Gold Gravel Mining Company, and in 1880 the 2200'
double compartment bedrock tunnel was started. Two years later
the main Ruby channel was struck and the mine was then opened up
on a large scale and profitably worked for 11 years, during which
time portions of two distinct channels were mined. The Ruby
channel, a quartz channel varying in width of pay gravel from 200'
to 600', was lost about the center of the property and about 2000' of
this channel still remains intact within the limits of the Ruby claims.
An intervolcanic channel was worked to the south boundary line of
the property about 1000' in 1894. Since 1896 the mine has been
leased and b'onded to two different parties who did some work
searching for the lost Ruby channel, without success. It is now
bonded to Copeland and Ailing, who work this property in connection
with the Bald Mountain and Bald Mountain Extension properties,
and are endeavoring to reopen them as one mine.

SIEBBA COUNTY. 57

Pay gravel in the Ruby channel averaged $3 per ton car, although
much richer gravel was frequently found. That in the intervolcanic
channel averaged $2.50 per ton car. The gold was mostly coarse and
easily saved, although the gravel from the intervolcanic channel was
somewhat cemented and the tailings ran high. Nuggets ranging from
1 to 45 ounces were common, and one was found which weighed
201.56 ounces, this being in the intervolcanic channel and along the
contact of serpentine and Calaveras bedrocks where most of the
coarse gold occurred. This so-called *Line of Coarse Gold' extended
in a north and south direction and was especially noticeable for about
800'. Quartz ledges rich in gold have been found in the Ruby, and
c»ne, although only a small ledge, has been considerably developed.
The general course of the three Ruby channels is southerly although
they have wound about and across each other.

The water-right in Rock and Little Rock creeks is owned and the
mine itself discharges from 3 to 4 miner's inches. As the Yuba
Hydroelectric Company has recently installed a power line to Forest
City, it is the plan of the operators to install electric power for
haulage and revolving trommels to disintegrate and thoroughly wash
the gravel before dumping it into the creek, to be worked over later
as heretofore.

The Scott property consists of the Bluebell (80 acres). Common-
wealth (160 acres) and the Manxman (160 acres), all locations. It
is situated on the lava-covered ridge at the head of Tennessee Gulch
and carries a good stand of timber. Although Tennessee Gulch was
worked in early days, Corlett took $45,000 out of one-half acre during
the year 1900.

This deposit is made up of old channel gravels, coursing N. 52° W.
The gravel, with quartz boulders, is 12^ deep, covered by 80' of pipe
clay, and lies on bedrock composed of blue slate and quartzite.
Water was encountered in too large a quantity to pump, the mine
flowing 100 inches.

Development work on the Scott consists of a tunnel through 100'
of slate, 60' through vein into pipe clay and 200' in intervolcanic
gravel carrying some gold. A winze sunk 80' through pipe clay

The Sierra Geneva property, covering 270 acres and nearly a mile
of channel, promises to become one of the most important drift mining
enterprises of the district. Much fine gold was panned here by old-
timers, but the main deposit was overlooked owing to heavy timber
and surface soil, until exposed a few years ago by a shaft in the Kate
Hardy quartz mine on the east. The channel crosses the big Kate
Hardy ledge from which rich surface pockets of gold undoubtedly
fed the gravel, and is entirely below a serpentine dike.

Bedrock is slate. An inclined shaft is being sunk to the bottom
of the channel on the northern rim to get into the dish of channel and
work upstream. The old, rich New Jersey claims adjoin on the wesi.

This property consists of one claim, the South Fork, 800 acres in
extent. There is some second growth timber on the property.

It was discovered in 1873, and in early days the old Blue Lead
was worked through the property. The present company leased the
property in 1903 and purchased it in 1910. Ten men were working
in 1913; three men were doing assessment work in 1914. It was
bonded in December, 1915, to Thos. Wilson of Manhattan, Nevada,
representing a Nevada company, who planned to soon begin active
work.

The channel is developed by a 5500' tunnel starting from Oregon
Creek, below Forest. It runs southeast for about 700', all timbered,
then runs 1800' N. 73° 28' E., where a raise of 16' struck gravel; then
HOC in gravel and islands of bedrock, then east for 600' and finally
1200' to the side line of the claim. The tunnel cuts a flat deposit of
gravel 1100' in width carrying free gold. Numerous raises have been
driven. It is probably a second period channel containing quartz
and fine gravel. The course is north and south and it is capped
with lava.

Equipment consists of one Temple-IngersoU air electric drill, com-
pressor, blower, blacksmith shop and timber shop. Electricity is used
for power and lighting. Adjoining mines are the North Fork and the

The Uncle Sam property consists of the Uncle Sam gravel claim and
the Uncle Sam Extension placer claim, unpatented. It covers a
length along the channel of 6000', the surface being rough and hilly.
There is good timber on the property on th^ north side of Ridge road.
It was discovered and first worked in 1850, closed in 1853, reopened
in 1869, closed in 1870, reopened in 1896 and closed in 1898. Swell-
ing bedrock was the reason for closing each time. It has again been
reopened, and after cutting through 1600' of old workings, the pay
streak was found in September, 1914. Fourteen-inch timbers which
have to be constantly repaired, are used to hold the swelling ground,
the average cost per running foot amounting to $8 for a tunnel
(9'x5')x8'.

The gravel is chiefly white quartz pebbles with some boulders, on
soft bedrock of chloritic schist, talc and serpentine. The gravel is
capped by rhyolitic tuf¥ which is in turn capped by basalt. The
channel courses southwest with pay gravel from 40' to 150' in width
and 6" to 4' in depth.

SIEERA COUNTY. 61

Rich gravel was uncovered in April, 1915, the strike appearing to
be the most important made in the district in years. The pay streak
averaged 35' wide, with the product yielding about $5 per car. Con-
siderable coarse gold and many small nuggets have been extracted.
The gravel is a portion of the White Bear channel, and is being
operated through the same shaft as the North Fork mine.

Power is purchased from the Middle Yuba Hydroelectric Company
at a rate of 1^^ per kilowatt hour. Fourteen-inch round timbers are
used, costing $3 per set. Ten men were employed in 1915 at a rate
of $3.25 per 8 hours. The run averages 4 cars (2500 lbs. each) per
day per man.

The property was worked in early days, and a second time by
Slavonians, working at intervals, about 1890. The White Bear
channel was faulted toward the south, and Winrod is now trying to
find the faulted part. Costa took over the property in July, 1906,
and it has been worked ever since. Twelve hundred feet of channel
yielded $200,000. A 2200' tunnel through slate passed the channel
and a total of about 1000' of upraises did not disclose it. A new
tunnel one-half mile north is 2000' long. Three raises were put up,
one 70' and another 116'. Prom the latter drift was run 200', then
raised 130', without passing out of bedrock. Twelve hundred feet of
channel, width of from 60' to 70', depth of pay 4', was worked from
the adjoining Monte Cristo claim.

The deposit is old river channel gravels coursing NE.-SW. The
gravel is composed of free white quartz lying on a bedrock of slates
and serpentine and capped with lava. The depth of the deposit is
5', the width 6' to 100'.

In May, 1916, work was resumed in the New York tunnel to find
the northern extension of the White Bear channel.

This property consists of the Wide Awake, Never Sweat, Germania
and Argentine locations, an area of 200 acres, with a length of a mile
and a half along the channel. It is situated on a lava-capped ridge
and there is considerable timber on the property.

The "Wide Awake was first discovered in 1884. It was worked as a
drift mine up to 1894 and produced $100,000. The Never Sweat pro-
duced $10,000 by ground sluicing, and Rouse piped out $10,000 from
the Argentine by hydraulicking. Four men were working and about
$900 was spent on development work in 1914.

The channel courses NE.-SW. and is developed by three tunnels.
The old No. 1 tunnel was run in lava 900', then in gravel 800', worked
by incline. No. 2 tunnel is 2000' long, part in lava. No. 3 tunnel,
20' below No. 2, ran 1000', 700' of which was in lava, to strike the
gravel, worked downstream at intervals for 1000', then ran north-
northwest 700'. A front channel is supposed to have been opened by
a new tunnel from the Never Sweat 'spell-out.' It is in slate 71',
then 276' in workings, including 200' of gangways in gravel worth
80^ a load.

The deposit consists of old Neocene channel gravel, 25' in depth,
capped with 500' of andesite and pipe clay, and lying on bedrock of
slate. The gravel is free, with some quartz and blue quartzite in
large boulders.

The front channel is 60' deeper than the back channel, but the
gravel is of the same character. Considerable water was encoun-
tered. Equipment consists of a boarding house, blacksmith shop, gas
engine and homemade sawmill.

J. Ross Brown began work on the Hawkeye in 1857, spending
$30,000. The property was purchased from Aaron Todd, and worked
by the present owners from 1900 to 1910.

The lower channel was mined in early days, though a block of
ground is said to be left, and later bedrock was worked. Idle at
present.

The deposit is old Neocene channel gravel on bedrock of volcanic
sand and ash, and capped with andesite. It is opened by the Wink-
eye tunnel 2200' in length with 300' in gravel, and the balance in
amphibolite and schist. An area of about 200' by 200' by 4' has been
mined in the upper channel. Water is obtained from the Sierra
Union water ditch, owned by T. Donohue Estate and J. H. Thomas,
Oakland. The Miner's Home property adjoins.

The company arranged in April, 1916, to drive a main drainage and
working tunnel from the Wisconsin side of the ridge, which will
effectively drain the property and avoid the use of pumps. The Uncle
Ham adit has been abandoned. Numerous small nuggets, weighing
from a few grains to 9 ounces, have been recently found in the
channel. The company is also exploring the Blue Point claim. A
tunnel was in 600' in 1916 and is advancing to tap the north end of
the channel adjoining the Ruby mine. A compressor and machine
drills are to be installed at once to facilitate driving of the new
Wisconsin tunnel.

The property consists of 1000 acres of unpatented placer locations,
covering a length of two and one-half miles. There is some small and
second growth timber on the claims.

The mine was worked extensively from 1883 to 1890; was idle for
17 years and then reopened in 1907 by the present owners. Ten to
12 men have been employed throughout the year, 35 during the season
from June to August, when 2000 cubic yards per day are hauled.

The deposit consists of old Neocene river channel gravels, the
gravel being small, cemented in spots and containing very few large
boulders. The channel is winding, but has a general N.-S. course.
The greatest depth is 200' and the pay gravel has a width of from
700' to 800'. It has a 40' lava capping.

There are 6 monitors, 2 being used at a time, and 6000' of 4' by 4'
tiume, with sawed blocks 1' square laid on a grade of 2^" in 12'. A
Hendy water power tramway handles boulders up to 5 tons.

Two thousand inches of water from Canon Creek and 1000 inches
from Cherokee Creek under a 240' head, are owned.

Transportation costs are $1.75 per 100 pounds from San Francisco.
Labor was paid $3 to $3.50 per day in 1914 and the cost of mining
300,000 yards was $40,000.

With an abundant water supply, hydraulicking was being done
with good returns in May, 1916.

This property consists of 60 acres of placer locations, covering a
remaining 400' of channel on the Pendola claim. It is situated on
the nearly flat surface of a valley and all timber has been cut.

It was discovered in 1852 by J. Joubert, brother of the present
owner, and has been run during the water season, from 4 to 6 months,
continuously for the last 14 years. Five men are employed.

The deposit is on the same channel as the Brandy City, Grizzly Hill
and Indian Hill mines. It is blue gravel 100' deep and 300' in width
lying on a slate bedrock, and is cemented on the bottom 4' to 6' deep.
The gravel averages about 10^ per cubic yard, the gold being flaky
like bran. Water is obtained from branches of Indian Creek. The
amount depends on rainfall, varying from 400" to 800" under a 140'
head. Monitors are used.

For impounding the tailings, there is a concrete dam, 54' high, 15'
to 18' thick at the bottom, 6' wide on the top, and 240' long ; 400,000
cubic yards were already stored in 1914 and 6' more were to be added
for a total capacity of 500,000 cubic yards. Houses, blacksmith shop,
pipe line, tools, etc., comprise the equipment.

Adjoining mines are the Indian Hill, Walker and Rossi, Italian
Diggings, and the worked-out Indian Ranch.

The Neocene Placer Mining Company's property consists of the
following claims: Cleveland and Sierra hydraulic (98.86 acres),
Oversight (110.45 acres), Gold Cup (136.61 acres), Keservoir (150.04
acres), Relocation (104.94 acres), Lincoln (58.54 acres), Baltimore
(20.70 acres), Good Hope (112.50 acres) and Southern (93.96 acres),
a total of 896.6 acres, all patented. It is situated on the gently
sloping plateau between Mount Pleasant and Scales, and there is
good timber on the property.

These claims have been worked since early days. In working the
channel, owing to the extreme difficulty of breaking up and trans-
porting the boulders which have to be handled by derrick or slack
(able, only about three hours a day can be devoted to piping during
a working water season of four months. Six hundred feet of the
channel has been worked, but very little of the lower gravel has been
touched in the last ten years, owing to the boulders. The method of
working is by sluices, tunnel and undercurrents. A system has been
used here which it seems could be successfully applied to other
hydraulic mines. The boulders are piled up across the channel and
then a small sluice with a 4^oj^ of 4" in 12' carries the fine sand and
gravel to the piled rock, there depositing them to form a dam. The
present company built a dam about four miles below^ Scales costing
$12,000, but it was filled up in one year by the piping and gravel from
natural erosion, and they are now considering putting in another one
«t a point where it is estimated that a dam 400' high would impound
all the available gravel in the district.

50' to 150' in depth in a channel coursing south on slate bedrock.
Most of the hydraulicking has been done on top gravel, 30' above bed-
rock. It is estimated that the gravels will average 50^ a cubic yard,
some ground in the Scales pit having gone $2 6r $3 per cubic yard.
Three men were working in 1915. '

Equipment consists of three derricks, slack cable hoist, pipe lines,
reservoirs, etc. An electric generating plant was installed about
1910, but was only used for a short time. Water, under 150' head,
is obtained from two reservoirs capable of holding sufficient water
for a two weeks' run.

This property consists of two claims, the Alhambra and Alhambra
Extension, an area of 40 acres covering a length along the lode of
3000'. It is situated on both sides of Canon Creek. There is no
timber on the property.

It was first located by Lindsay and leased by a Scotch company
(Sutherland). Abandoned and relocated by P. Carmichael. Bought
from him by present owner in 1895. Freeborough has taken out
$10,000 from pockets. Assessment work only was being done in 1914.

The lode has been developed by a 350' tunnel on the vein in the
banging wall, a 150' shaft and two crosscuts 300' and 35' in length
toward the foot-wall. Very little stoping has been done.

The deposit is along the contact of serpentine and slates. There is
a 140' fissure filled with mariposite, quartz and altered rock, in which
free gold is found in decomposed stringers in the slate hanging wall.
The ore contains free gold, pyrite and galena. The quartz veins vary
from 2' to 3' in width, strike N. 57° W., dip 45° E., and have a proven
length on the surface of 3000'.

Water rights on 600 inches of water under 130' head from Canon
Creek are owned and the property is equipped with a Huntington
mill, Sears roller quartz mill, house and blacksmith shop, and a saw-
mill built in July, 1914.

It was bonded to M. Caulfield and J. S. McFarlane of Downieville
and a small crew of men put to work in 1915. Ore was being taken
out and further work was planned for the spring of 1916.

76 MINES AND MINERAL RESOURCES.

Alhambra Ifiine. Owners, P. 0. Richardson, Downieville; J. H.
Rixey and E. Spoindli, Ilayward.

Location: Downieville Mining District, See. 21. T. 19 N.. R. 11 E , 6 miles by
trail or 9 miles by road southeast of Downieville. Elevation 5000' to 5500'.
Bibliography: U. S. Geol. Survey Folio 37, Downieville.

This property consists of eleven claims, including the Alhamhra,
Alibaba, Comet and Jumbo. There are 220 acres in all, with a length
along the lode of 6000'. The surface is steep, rising from Jim Crow
Canon to the lava-capped ridge.

The property was worked by Jesse Carney in 1875 with a 5-stainp
mill. The present owners bought it in August, 1912, and located the
northern extension. Three men were working in 1914, two in the
mine and one in the mill.

The Alhambra vein is developed by a 360' tunnel on the vein, which
reaches a depth of 175' below the outcrop, and 300' of open cuts on
the surface. On the Comet claim there is a tunnel 350' through slate,
then on the ledge south 200'. One hundred feet above the lower
tunnel 250' has been driven on ledge to the south. There are
numerous crosscuts on the Comet, but the ground is not well opened
up, and very little ore has been stoped.

There are six parallel veins on this property. The Alhambra vein
may or may not be the northern extension of the Comet vein. The
ore contains free gold and arsenopyrite, and lies between a porphyry
foot- wall and a hanging wall of slate. The whole country rock is
decomposed and altered. The vein varies from 6' to 8' in width,
strikes N. 10° W. and dips 80° W. The 30' lode on the Comet
property is said to vary from $1 to $9 per ton for a width of 14'.

There is good timber on the property. The equipment consists of
a sawmill driven by a 10-h.p. Peerless gasoline engine, a Rix 20-h.p.
6"x 6" Duplex upright compressor, lighting dynamo, a complete o'
Sears roller mill driven by a water wheel, mill building and board-
ing house.

Gasoline and water are both used for power; 12 inches of water
under 300' head is available.

80 MINES AND MINEBAIi RESOURCES.

The Bullion vein has been developed by three tunnels. The Upper
tunnel is a 180' crosscut and 1070' driven northwest on the vein; it
is inaccessible. The Middle tunnel, 180' below, is a 900' crosscut and
300' on the vein, but is caved for 400'. The Lower tunnel, 130' below
the Middle tunnel, is an 1100' crosscut adit with 75' to go to cut the
vein. There are 600' of backs running into the hill from the Upper
tunnel. Ore has been stoped for 80' above the tunnel level, 10' by
200'. A winze in the Middle tunnel 20' deep showed a 9' vein of ore
going $12. There are surface workings only on the California vein.
The Lower tunnel is open in slate and serpentine. It will be neces-
sary to drift 400' northwest on the vein from where the Lower tunnel
will intersect it to strike the big shoot.

The veins are both quartz fissure veins, carrying free gold, pyrite
and galena. The foot-wall is slate, the hanging wall -is * porphyry,'
red oxide of iron full of quartz stringers, and there is gouge on both
walls. The Bullion vein varies from 3^' to 12' in width, strikes
northwest, dips 50° NE., and has a proven length on the surface of
7500'. Three pay shoots developed, one 70' long and 3^' wide plated
$15, another 100' by 5', and a third 300' by 6' plated between $7.50
and $12. Between the Upper and Middle tunnels there are 30,000
tons of ore in main shoot reported to average on the plates $7.50.
The California vein shows a width on the surface of 6'. It strikes
east and dips 50° N.

There is a new two-story boarding house and a blacksmith shop on
the property, also cars, rails and pipe.

Water is used for power, 150 inches under a 1000' head is available
for six months of the year from Black Canon, and 27 inches is
obtained from the Middle tunnel under a 400' head.

A new adit in which rails and an air pipe line are being placed, was
being driven in 1914 to cut the vein which occurs in a contact of
serpentine and porphyry. In September, 1915, a contract was let
for extending the lower adit 100', it being expected that it will inter-
sect the rich shoot formerly worked near the surface, giving 400' of
backs on the vein. Henry Appilom was superintendent.

An electric plant was installed and put in operation early in 1916,
supplying the various buildings with lights. This mine is run in con-
junction with the Monarch, which is also bonded to Gillespie. By
the middle of February, 1916, shaft sinking had reached 350' and was
progressing rapidly. A 10-stamp mill was working one shift, and an
IngersoU-Rand compressor was being installed to facilitate mining.

The Colorado-Yellow Jacket mine consists of three claims, the Colo-
rado, Colorado Extension and Yellow Jacket, a total of 37.66 acres of
patented ground. After having been practically abandoned, this
mine has suddenly become one of the most promising in the district.
In July, 1914, the caretaker in charge, an experienced prospector,
discovered a large shoot of gold-bearing quartz, and the owner
returned to develop the property. An electrically operated air com-
pressor will be installed and ore will be opened up by drifts. The
mine is on Kanaka ridge and is a south extension of the El Dorado.

There are two claims in this property, the Dreadnaught, 20 acres,
and the Seneca Fraction, 5 acres, covering a length along the lode of
1600'. They are situated on the northwest bank of the South Fork
Kanaka Creek, and have some timber on them.

Development consists of a 280' crosscut to the vein and 320' run
on it, reaching a vertical depth below the outcrop of from 200' to 250'.
A raise connects with old workings, and a winze has just been started.

The vein is a quartz filled fissure, the foot- wall being serpentine and
the hanging wall schist. It averages 4' in width, strikes N. 12° W.,
and dips 45° W., and has a proven length on the surface of 1500', but
may be faulted. A 200' pay shoot was encountered.

This property has been under the present ownership for the past
ten years. It is now bonded to Walter Harris, F. B. Delaney and
Jerry Wood, all of Alleghany. Harris and one man were working
the property in 1915. The total output to date is between $50,000
and $100,000. It is equipped with a 1-stamp mill.

cisco ; formerly was bonded with the Emerald quartz group to Clifford
Smith and others, of San Francisco.

Development consists of a 643' adit on a vein, which may not be
the Elcy vein, also a 75' shaft and open cuts.

There are two main veins, the Elcy and Mariposa, and a number
of other veins and 'blowouts.' The Elcy is a quartz fissure vein
containing free gold, pyrite and arsenopyrite, between a foot-wall of
slate, and a hanging wall of granite ('porphyry'). It varies from
2^' to 4' in width, strikes north, following the contact, dips 45° E.,
end has a proven length of 2000' on the surface. The Mariposa vein
varies from 18" to 2' in width, strikes northeast and dips vertically
between walls of granite. Ore in the Elcy shaft ran $27, and that

Three claims, the El Dorado, the El Dorado Extension and the
Terrible, make up this property, which adjoins the Tightner. There
are 45 acres covering a length along the El Dorado lode of 1800' and
along the Terrible of 1500'. It is situated on the steep south side of
the South Branch of Kanaka Creek and contains some timber.

The owners have held this property for 35 years, but in 1915 it was
bonded by Fessler Brothers to J. L. and J. W. Armstrong of Alle-
ghany. A total of $150,000 had been taken out to 1914, the greater
part by Fessler.

The El Dorado is developed by an 1100' tunnel on the vein, 900'
bearing S. 58° to 70° E., then 200' bearing S. 2° W. The vertical
depth below the outcrop, at the end of the tunnel, is 700'. At a
distance of 980' in from the tunnel mouth is a 25' winze in good ore ;
800' in an 18' main raise. At 980' there is an upraise of 225', with
ore stoped on each side for a width of 30'.

The El Dorado vein is a fissure with well defined walls, filled with
quartz, mariposite, and altered wall rock and carrying free gold and
arsenical pyrite. The foot-wall is serpentine and mariposite, the
hanging wall amphibolite schist. The vein varies from 3' to 10' in
width, strikes S. 58° to 78° E., curving and striking S. 2° W., dips
60° SW., and has a proven length on the surface of 1500'. Three pay
shoots were encountered, as follows: 190' from mouth of tunnel a
pay shoot 40' long and 3' wide ; 800' in, one 60' long and 3' wide ;
980' in, one 125' long and 2' to 3' wide. Ore from the inside stope
averaged $40 per ton for a width of 2'. The ore carried 1.2% con-
centrates, worth $70 per ton.

Mine equipment consists of blacksmith shop and a cabin, tools, a
compressor (water power), 2 Waugh and 1 Ingersoll drills. The
reduction equipment consists of a 10-stamp 750-lb. Risdon mill and
2 Johnson concentrators driven by a Pelton water wheel.

A water right to 150 inches under 115' head from South Fork
Kanaka Creek is owned.

There is a total area in this property of 887 acres, all patented, as
follows: Franklin, Napoleon, Luther, Wallace, Hull, Four Hills,
Reynolds and Southeast Extension of Four Hills, quartz claims of
180 acres total ; Whippoorwill placer, 160 acres, and Gibraltar placer,
147 acres, covering the outlet of Spencer Lakes and Middle Fork
Yuba River; timber land in the SW. i of Sec. 11-21-11; SW. i of
Sec. 35-22-11, SE. and NE. i of SE. i Sec. 11-21-11, 400 acres. The
property covers a length along the lode of 3000'. It is situated on the
high lava-capped ridge between Jamison Lakes and Gold Valley near
the headwaters of East Fork and Middle Fork of the North Fork
Yuba River. There is very little timber at the mine, but the timber
tracts are well wooded.

The mine was worked in early days by Mexicans. Later a 4-stamp
mill was erected by a man named Spencer. The Four Hills Company
took out from $250,000 to $500,000 in one pocket from a hole 15'
below the surface. Since the purchase of the property by the present
owner, very little real development work has been accomplished, and
only pocket mining has been done the last two years. Pockets rang-
ing from $1500 to $6000 have been taken out from near the surface
during this time. Two men are working the outcrop.

The main vein is developed by a 300' vertical shaft. A drain
tunnel crosscuts 1100', then runs 200' south on the vein and cuts the
shaft. at the 150' level. From this point 1300' of drift was run south
on the vein. Sixteen hundred feet was run on the vein by the Upper
Mill or Mexican tunnel into the hanging wall to intersect the raise.
Numerous crosscuts have been run at different points in the workings
without results. A number of shoots have been stoped, ranging
from 100' to 300' in length; *Big Stope,' from the mill level to sur-
face, a width of 6' and length of 200', was said to average $60 per
ton; $20,000 is said to have been taken from one *Main Stope' put up
70' from the Drain Tunnel when the ore pinched out, and by drifts
from the shaft 100' below the Drain tunnel level for a length of 300'.

The above is the only vein so far developed, though there are others
on the property. It is a quartz filled fissure vein. Large bodies seem
to be formed by the intersection of veins and stringers with the main
fissure, and the ore is said to be enriched at these points. The ore
carries free gold near the surface, many rich pockets of oxidized ore
having been taken out at shallow depths. In some places sulphides

(pyrite, chalcopyrite, galena and arsenopyrite) come to the surface.
The walls are quartz porphyry and schist, and the vein varies in
width from 1' to 20', the average being 4' to 5'. On the north end it
strikes east, on the south end north, forming a horseshoe. It dips
45° SW., and has a proven length on the surface of 3000'. There are
said to be a number of shoots of ore averaging $5, which have never
been stoped. On the surface, there is an outcrop 20' in width, in
which the best values occur along the foot and hanging walls, the rest
of the vein being massive white quartz. This property in many ways
resembles the Plumas Eureka, being on the same belt of quartz
porphyry as the Plumas Eureka, four miles to the north, and the
Sierra Buttes, ten miles to the south.

Equipment consists of Pelton wheels and generator capable of
developing 300 horsepower, but it would cost $600 to put them in
shape. There is also an electrically driven compressor, a hoist driven
by compressed air, and a 20-stamp mill, 850-lb. and 950-lb. stamps,
only 5 of which are being used.

Water from Spencer Lakes is taken down to Middle Fork under
950' head, and there is also a water supply from springs.

Adjoining mines are the Empire and Sierra Iron.

The Gold Canon property, embracing the Gold Canon patented
claim and the Gold Queen, Fortune and Gold Canon Extension loca-
tions, a total area of 72 acres, lies on both sides of the Middle Fork of
the Yuba River, which forms the boundary between Sierra and
Nevada counties.

The mine was discovered in the '60 's. It has been worked at
intervals since and is credited with a production of $730,000, the
greater portion of which came from above the adit level. There are
two main quartz veins known as the Gold Canon and Gold Queen,
but most of the exploratory work has been done on the Gold Canon
vein. The Gold Queen vein has been opened to a depth of from 30'
lO 50' by a 100' crosscut and a drift on the vein 150' in length. The
development work on the Gold Canon lode, which can be traced for
a distance of 1800' on the surface, consists of an adit tunnel, driven
as a crosscut a distance of 600' and then on the vein for 1600', giving
a depth below the outcrop of from 80' to 300'.

An incline shaft was sunk to a depth of 370' and connected with
the adit, and 160' below the connection a drift was run northwest on
the vein a distance of 500'.

The Gold Canon vein is said to vary in width from a few inches to
4', and the Gold Queen to average about 2'. The veins are quartz-
filled fissure veins with a general strike of N. 40° W., and a dip of
45° NE.

They cross the contact of serpentine and amphibolite schist, the ore-
bodies occurring in the schist within a few hundred feet of the
contact. The well known Plumbago and Tightner mines occur in
this same area of amphibolite schist and serpentine and the occurrence
of orebodies and the mineralogical content of the ore in the Gold
Canon vein is characteristic of the other mines of the district. The
ore is quartz carrying free gold and arsenopyrite, containing a high
percentage of gold ; some pyrite, chalcopyrite, galena and zinc blende.
The ore shoots are as a rule small and irregularly distributed
throughout the vein, generally being found near the foot-wall.

The property is equipped with a 5-stamp mill (1000-lb.), a 400
cubic foot Hendy air compressor, a small 8 x 10 duplex hoist, drill
tools, boarding house and other buildings. Electric power is supplied

The Golden King consists of two claims, the Gold King and Gold
King Extension, an area of 40 acres and covering a length of 3000'
along the lode on both sides of Kanaka Creek. It was last worked in
1895. Production 1890-1895, $250,000.

The vein is of the quartz fissure type, containing free gold and
arsenopyrite, with a foot-wall of schist and a hanging wall of serpen-
tine. It varies from 1' to 12' in width, strikes northwest and dips
45° NE., and has a proven length of 3000' on the surface.

It was developed by a 400' vertical shaft, on the west side of the
creek, 100' above the creek level, and an adit tunnel 800' long, driven
on the vein from the collar of shaft. Ore stoped to the surface is
said to have gone $25 per ton. On the 400' level a drift was run
from the shaft, northwest 600'.

The mine is equipped with a good 10-stamp Hendy mill and 3 Frue
vanner concentrators driven by water and steam, also a bunkhouse,
superintendent's house and assay office.

The Ironsides mine adjoins the Alhambra and consists of eight
claims, the Sierra Del Oro, South Extension, North Extension, North
No. 1, North Extension No. 2, East Extension, West Extension, and
West Extension No. 1, a total of 160 acres, covering a length along
the lode of 7500'. It is situated in a steep canon dropping from the
lava covered divide between North Pork and Middle Fork Yuba
River. Some timber grows on the property.

Jack Ironsides discovered this property in the '60 's. A small mill
was erected and a little stoping done, but later the mill burned down.
The ground was relocated by the present owners in 1910. From nine
to fourteen men worked up to May, 1914, and it was expected to
work six or seven men during the winter of 1914-1915.

The deposit includes the Ironsides and some other parallel veins
which have not been developed except by open cuts. The Ironsides
is a fissure vein with a filling of quartz, slate and porphyry, carrying
free gold, arsenopyrite and galena, cutting the strike of the slates at
an angle. Both the foot and hanging walls are sometimes slate and
sometimes porphyry. It varies in width from a small stringer vein
to 16', strikes north, dips 61° E., and has a proven length on the
surface of 7500'. The main pay shoot developed was 200' long and
from 4' to 12' wide.

The Ironsides is developed by an 80' crosscut to the vein, then 600'
on the ledge to the first shoot 110' long (stoped to surface). At a
point 60' further the top of another shoot 32' long and 3' wide was
struck, and a winze sunk 10' in ore. The upper tunnel, 70.5' above
the lower one, is an 80' crosscut driven to the vein, then along it for
240' through pay ore, which was stoped 72' to the surface. A winze
was sunk 200' from the crosscut for 42' in good ore. A short tunnel
on the south side of the gulch, 52' above the lower tunnel, struck
another shoot 90' long, which was worked to the surface. A crosscut
tunnel 1500' long from the creek would give 575' of backs below the
lower tunnel level.

A blacksmith shop, a lighting dynamo, and a Nissen 1-stamp mill
having a capacity of 8 tons of quartz per 24 hours, driven by a 12-
h.p. Fairbanks-Morse distillate engine, comprise the mine equipment.

The Pilgrim ditch, two miles in length, takes water from Harris
Meadow. A minimum of 28" and a maximum of 150" under a 450'
bead is available. The operators were putting in a pipe line in 1914.

The Jim Crow property consists of one claim, the Jim Crow, twenty
acres in area, located in 1897 by the present owners, and covering a
length along the lode of 1500'.

There are two veins, the North Extension of the Elcy, and the
Blanket vein, both quartz fissure veins. The former varies from 18"
to 3' in width, strikes north and dips 45° E. The foot-wall is slate,
the hanging wall granite. The Blanket vein varies from 6" to 2' in
width, dips 10° E. and has slate walls.

There is a 40' shaft driven to the Blanket vein and a 400' tunnel on
the contact. No quartz was encountered, so the mine was abandoned.

Bibliography: U. S. Geol. Survey Folio 37, Downieville.

The property consists of two claims, the Jumper and Tippecanoe, a
total of 40 acres, covering a length along the lode of 3000'. It is
situated south of the South Pork of the North Yuba at the head of
Slate Castle Ravine, extending to the top of the ridge, between Slate
Castle and Secret ravines. There is good timber on the property.

Wm. Kidd first located the claims in 1900. They were purchased
from Kidd by Julian and Sergent, lapsed and relocated by the present
owner in 1910. Two men were working in 1914, putting ore through
an arrastra, run by means of an overshot wheel, which used water
from a large spring.

There are two veins on the property: the Big Ledge and Little
Ledge, parallel and 250' apart. No work has been done on the Big
Ledge, which is hard quartz. The Little Ledge is a 3^' vein com-
posed of clay gouge with sulphides. It strikes north, and has a
proven length on the surface of 300'. The dip is probably vertical,
but may be a little to the east.

This property consists of the Kate Hardy and Derelict claims,
patented, covering 2900' along the lode; also the Blue Bird, Blue
Bird Extension, and Hooligan unpatented; and an undivided half-
interest in the Brush Creek Placer claim ; a total area of 240 acres.
The Kate Hardy lies on the south side of Oregon Creek, and the
Derelict on the north. There is some timber on the property.

The Kate Hardy mine has been worked at intervals since about
1860 and has a reported production of $225,000. Baggs purchased
the property from Tyler Dudley in 1908. Twelve men were
employed, 2 on top, 7 in the mine, and 3 in the mill, in 1914.

The vein on the Kate Hardy is developed by a lower tunnel 650'
long, the face being 275' below the surface, and an upper tunnel, 300'
long, 160' above the lower one. A raise, 360' in the lower tunnel,
strikes a middle tunnel 90' above, 300' in. There is a crosscut 27'
long, and 360' in on the lower tunnel, to the hanging wall. From the
bottom of a 45' winze from the lower tunnel crosscut, another driven
to the hanging wall shows 15' of quartz. A. tunnel on the Derelict
claim is run 150' on the vein at the same level as the lower Hardy
tunnel. All the tunnels are run on the foot-wall. A surface crosscut
on top of the hill, 350' to 400' beyond the face of the tunnel, shows
42' of quartz. The present operators propose to sink 500 feet.

The deposit is a quartz fissure vein, the ore having a ribbon struc-
ture and carrying free gold, pyrite and arsenopyrite. The ore is
partly oxidized, but contains considerable quantities of sulphides,
which commonly consist of small patches of finely crystalline pyrite,
the latter rarely going over $10 per ton. The foot-wall is serpentine,
and the vein varies from 10' to 30' in width. It strikes N. 24° W.

The Kenton property consists of the Kenton, King Solomon, and
King Solomon millsite locations, covering 60 acres, and extending
:>000' along the lode.

It was discovered in 1860 and is supposed to have had a large pro-
duction. Eight stamps were installed in 1864 and 10 more added in
1882, but for the last few years practically no gold has been obtained.
It was last worked about 1912 by Judge Polk, of Los Angeles.
Bonded in April, 1915, to New York people, represented by Judge
Case.

A 90' crosscut tunnel strikes the vein 125' below the outcrop, 400'
was drifted on the vein and from 4^' to 9' stoped on the hanging wall
side. A crosscut tunnel runs 120' below the upper tunnel, 513' to the
ledge and 14' south on the vein. On the King Solomon claim there
is a 150' crosscut tunnel and a 350' drift south in broken country
rock, but no well-defined vein was encountered.

The Kenton quartz vein carries free gold and patches of pyrite,
snd arsenopyrite throughout. It varies from 4' to 16' in width,
strikes a little east of north and dips 45° E., between walls of schist
or diorite.

Besides the old 18-stamp mill containing 4 Union vanners, there is
a boarding house and bunkhouses.

100 MINES AND MINERAL RESOURCES.

The Lost Treasure property consists of two claims, the Comet and
the Lost Treasure, an area of 40 acres covering 1500' along each lode.
The surface is steep and rugged, with a good stand of timber. It
was located in 1909 by the present owners.

The Lost Treasure vein is developed by a 70' tunnel on the vein,
reaching a depth below the outcrop of 40', and the Comet vein by
open cuts and a shaft 12' deep.

The Lost Treasure vein, 400' east of the Comet vein, is a fissure
filled with quartz and porphyry and carrying gold, arsenopyrite and
pyrite, with some free gold near the surface in oxidized ore. Both
walls are porphyry. The vein is from 1' to 8' in width, strikes a
little north of west, dips 45° S., and has a proven length of 1000' on
the surface. Bunches of arsenopyrite, but no pay shoots, developed.
The Comet is a quartz fissure vein carrying free gold and pyrite. The
walls are porphyry. It is 2' wide, strikes east, dips 45° S. and
has a proven length on the surface of 1500'.

The mine is within two miles of the Middle Yuba Hydroelectric
Company's line, but a blacksmith shop with tools is the only
equipment.

The Brush Creek mine lies one mile to the west, the Kate Hardy
one and one-half miles to the south.

The Mammoth Springs quartz property consists of three claims,
the Contact, Contact No. 1 and Contact No. 2, a total of 60 acres,
covering a length along the lode of 4500'.

The deposit consists of the Talc contact vein and a quartz vein
100' to the west. On the Talc vein there is an upper tunnel driven
500' on the ledge, and reaching a depth of 150'. From the face of
this tunnel there is a 250' incline shaft. A tunnel, 150' below, will
have to be driven 200' further to reach the shoot. The Quartz vein
is developed by a 30' shaft and a 100' tunnel on the vein reaching a
depth of 50' below the outcrop.

The Talc vein carries free gold in talc schist and 1^% of arsenical
pyrites. The foot-wall is serpentine, and the hanging wall slate.

This property consists of three claims, all patented: the Ophir
(17.87 acres), the Mariposa (15.34 acres), and the Eclipse (20.65
acres).

The last work was done about 15 years ago. The total production
is said to be $118,000.

The property is developed by three tunnels. The upper tunnel,
300' long, reaches a depth of 70' below the outcrop; the middle
tunnel, 70' lower than the first, is 250' long, and the lower tunnel, 70'
below the second, is 600' long. They are all driven on the vein. A
crosscut tunnel started 180' west of the lower tunnel has been driven
a distance of 200'. The vein is worked from the 180' level in a winze
to the upper workings. There is a 200' prospect tunnel and winze on
the Eclipse vein from North Fork Kanaka Creek, and from the west
side of the creek a 300' tunnel on the Ophir vein showed it to be from
18" to 4' wide, 300' below the surface. Some rich ore was produced.
The vein is spotty, and productive in specimen ore.

The Mariposa and Ophir vein is a fissure vein, from 18" to 3' in
width, striking N. 30° W., and dipping 45° NE. The foot-wall is
serpentine and the hanging wall schist.

Property bonded to J. R. Hilmsley and Clay Covenay in August,
1915. Arrangements have been made to install electric power.
There is a 5-stamp mill on the property.

102 MINES AND MINERAL RESOURCES.

Mexican Group. Owners, T. J. Jerome and Ed York, Downieville.

Location: Downieville Mining District, Sees. 25 and 26, T. 20 N., R. 10 E.,
1 mile east of Downieville, thence 44 miles by road southwest to Nevada
City (N. C. N. G. R. R). Elevation 4000'.

Bibliography: U. S. GJeol. Survey Folio 37, Downieville.

The Mexican group comprises five locations, the Colorado, Golden
Star, South Fork, Mexican No. 1 and No. 2, a total of 100 acres, with
12 acres of patented land on the river. The claims are situated on
the high ridge east of Downieville, and are cut through by the Yuba
River. There is some timber on the property.

Mexicans located the property in early days, and it was later
relocated by Judge Davidson, who did assessment work for 30 years.
It was again relocated in 1906 by York Brothers, who have since been
doing assessment and development work.

The Mexican and a parallel vein, 40' west, have been worked by
two tunnels. The lower tunnel, 30' above the road, is in 350' on the
vein, and the upper tunnel, 125' vertically above it, is in the same
distance. Both tunnels are in a pay shoot, shown by open cuts to be
900' long on the surface. Another vein, the South Fork, has been
developed by surface cuts only. The Hartley vein has been developed
by a lower crosscut tunnel 300' long, with 50' driven on the vein;
80' above this a crosscut tunnel was driven 70' and 150' drifted on the
vein, all in ore. In 1914 stoping was being done above the upper
tunnel to the surface, 45' above. One hundred fifty tons of ore
stoped frojn July to November 15, milled $3.30.

The deposit is in quartz fissure veins in slate, the vein filling being
quartz and slate, carrying free gold, arsenopyrite and pyrite. The
Mexican vein varies from 2' to 15' in width, the parallel vein averages
4' to 5' in width. They strike north, dip 70° to 80° E., and have a
proven length on the surface of 3000'. The South Fork vein is a con-
tact vein carrying pyrite, but no arsenopyrite. The foot-wall is
quartzite, the hanging wall slate. This vein is 20' wide, strikes
north, and dips east. The Hartley vein runs across the formation,
striking northeast, and dipping 60° NW. It is 5' wide on the foot
and hanging wall with a 5' horse between.

A mill completed in June, 1914, is equipped with a Hendy mill
having five 900-lb. stamps using 50-mesh screens, and a Johnson con-
centrator. There is room in the building for 10 stamps.

Electric power is obtained from the York Electric Plant, which
supplies Downieville. Three thousand inches of water from the
Middle Fork of North Fork Yuba River are available.

The Minnie D. quartz property has a total area of 30 acres. The
two claims, the Lucky Holm (20 acres) and the Minnie D. Fraction
(10 acres), have a length along the lode of 2300'. It is situated on
the steep west side of the gulch formed by the North Fork of Kanaka
Creek, with the outcrop on the top of the hill. Located in 1905 by
the present owner.

It is developed by two tunnels, 60' apart vertically. The upper
tunnel follows the vein for 150' ; the lower tunnel, 320' long, struck
the vein 25' in. The face is 100' below the surface. The following
notes are largely from H. G. Ferguson's report in Bulletin 580, U. S.
Geol. Survey:

The vein strike varies from N. 65° W. to N. 80° W. and the dip
averages 46° NE. It cuts sharply across the schistosity of the
iimphibolite and is, in several places, joined by stringers from the
foot-wall side. The thickness varies from a maximum of 15" to prac-
tically nothing, the usual width being about 2". The quartz is dis-
tinctly banded and in places approaches comb structure. It contains
nests of little pyrite crystals, accompanied by specks of sphalerite and
gafena. Free gold is found where the stringers from the foot-wall
intersect the vein. The gold is in the quartz near the sulphides and
is very commonly smeared out along slips in the vein. A rare occur-
rence of gold was seen in the presence of minute specks on the faces
of pyrite crystals.

The Tightner, Morning Glory and Martin Rorig mines adjoin.

Monarch Mines. Owners, J. H. and F. M. Lee, Sierra City. Bonded
to R. G. Gillespie, Pittsburg.

Location : Sierra City Mining District, 3 miles northwest of Sierra City ; Blairs-

The Monarch Mines property consists of 520 acres of locations
covering a length along the lode of 12,000'. They are the Alconda,
Mountain Lily, Monarch, Homestake, Miner's Dream, Independence
No. 1, Snowflake (water right), besides 20 other claims. It is located
along the west rim of the ridge from Sierra Buttes, and there is some
good timber on the property.

104 MINES AND MINERAL RESOURCES.

Lee Brothers located the claims in 1909. They were worked in
1910 by Thompson and bonded in 1912 to Gillespie, who began work
in August, 1913. A total of 35 men were working two shifts, 12 in
the mine and 4 in the mill, at that time.

The vein is developed by a 100' shaft in the hanging wall, a 225'
crosscut, which is being driven into the foot-wall, and 500' driven on
the vein. An old 170' shaft is connected by a 60' incline.

The vein is made up of quartz stringers in decomposed amphibolite
at the contact of serpentine, amphibolite and slate. There is 100' of
decomposed rocks with stringers, 6' of which has been worked. The
foot-wall is serpentine, the hanging wall is slate and * porphyry,' prob-
ably oxidized amphibolite. It strikes N. 38^ W., dips 60° to 65°
NE., and has a proven length on the surface throughout the claim.
A pay shoot 100' long has been developed. The ore is oxidized and
free milling.

The shoot of rich ore, encountered early in 1916 on the lower level,
has been traced for 150' along the foot- wall, and is apparently
developing into one of the best veins yet discovered in the property.
The management is considering driving a long working tunnel to open
the ore bodies several hundred feet below the present workings.
This tunnel would also displace the shaft as the main working
avenue.

Mine equipment consists of a 150-k.w. Pelton hydroelectric
generator unit, 12,200' of pole line, 2-drum Hendy electric hoist, 220-
volt, 50-h.p. motor, sawmill of 5000 feet a day capacity, large
bunkhouse, hoisthouse, and blacksmith shop. There is a 20-stamp
mill equipped with 10 new Taylor Grass Valley stamps and 10 old
stamps in a new corrugated iron building. A new pump and an air
compressor are being installed and a large dam is being constructed
in Black's Canon to hold the tailings. Twenty stamps were dropping
in 1916. Dan McMonigal is manager.

In February, 1916, the vein on the 200' level had been opened for
over 300' by the west drift. It averages 7' in width and is of milling
grade. The shaft is to be deepened to 400', giving 700' of backs, and
a main working adit will be driven later.

Power is obtained from the South Fork of North Pork Yuba
through an 8300' ditch, carrying 600 inches of water with a 150' head.

The Sierra Buttes properties adjoin on the southeast.

The Oriental group consists of the following claims, all patented :
Carrolson, Ethel, Pittsburg, Alta, Alta Annex, Admiral, Blue Jay,
Oriental and Oriental Millsite, making a total of 153.4 acres. The
mine is situated on the north side of Kanaka Creek.

The mine had been idle for some years previous to 1915. One shoot
between the surface and the 400' level produced $3,000,000, of which
amount $734,000 came from a single area 14' by 22'.

The following description is drawn nearly verbatim from H. G.
Ferguson's report in Bulletin 580 I, U. S. Geol. Survey:

The vein is reached by a 4150' tunnel from the canon side at an
elevation of 4050', which, for the most part, passes through amphib-
olite schist, but from the 3600' point to the face is in much altered
microcline granite. Two veins developed on this level. The southern
vein cuts the granite, but is here small and poorly defined. The
northern vein is at the northern contact of the granite and schist and
has been developed only on this level. For about 400' it follows the
contact very closely, but at the west end it passes first into granite
and then into schist. The southern vein is developed on several
levels.

The strike varies, but averages about N. 70° W. The dip is from
30^ to 35° N. in the lower levels, but steepens to 50° in the upper
levels. In places the quartz pinches out for short distances, but on
the whole it is fairly persistent, with a maximum width observed of
10'. All stoping was done along the foot-wall, generally the lower
2' of the vein being mined. Small quartz stringers are very common

in the schist near the vein, and pyrite occurs in the quartz in small
patches half an inch across. The granite near the vein carries pyrite
and much carbonate and is said to carry gold. In the rich ore, how-
ever, there is the same association of gold and coarsely crystalline
arsenopyrite that occurs in the other mines of this district.

Operations were resumed in May, 1915, with 10 men employed by
the Croesus Gold Mining and Milling Company, with Walter B.
Pearson in charge. A 10-stamp mill with two 6-foot Prue vanners
was placed in commission December 5. Bunkhouses and other build-
ings have been completed.

[This company is said to have mined about 5000 tons from below
the tunnel, but abandoned the property in 1917. — C. A. Logan.]

This property consists of one patented claim, the Osceola, 20.66
acres in area. It is situated above the North Fork of Kanaka Creek.
Development work was in progress in May, 1913.

H. G. Ferguson* says the following regarding this property :
''The upper tunnel, at an elevation of 4370', follows the vein N.
60° W., for about 40', and then for the same distance N. 47° W. The
dip is here 55° NE. The vein consists of white quartz and is 6' wide
at the portal and 2' at the face. The lower tunnel at an elevation of
4200', has a length of 1650'. The strike of the vein in the outer part
of this tunnel is N. 45° W., in the central part between N. 60° and
70° W., and near the face N. 25° W. Near the portal the dip is 50°
NE. In the central part it steepens to 70° or more, and near the face
of the tunnel it flattens to 35°. The vein has a maximum width of

10', but between points 650' and 1150' from the portal the quartz
pinches out and the tunnel follows a crushed zone in the schist.
From the 1150' point to the face the quartz is continuous. Near the
portal there is a split in the vein and a part goes ofif to the north with
a dip of 60° W. In the richer patches the quartz contains narrow
dark bands of crushed arsenopyrite, and near these free gold is
found. The ore, so far as could be seen, is similar to that of the
other mines in this district. * * * A large amount of ore has
been taken out from this mine, but the production is unknown."

The Oxford group consists of the Good Hope, Good Hope Extension
No. 1, No. 1 South, No. 2 North and No. 3 North, claims, all patented.
The total area is 100 acres, with a length along the lode of 6000'.

The main tunnel starts from the east side of the claim, at an eleva-
tion of 3400'. This tunnel crosscuts the slate, and reaches the vein
at 650', from which point 800' is drifted on the vein to the north and
100' to the south. Another tunnel, on Extension No. 1, is a 150'
crosscut and 50' drifted on the vein. On Extension No. 2 a 250'
crosscut cuts the vein 80' from the mouth, and drifts north on the
vein for 30'.

The deposit is in a quartz fissure vein 50' away from the contact
of slates and serpentine. The ore is oxidized, the quartz carrying
free gold, but arsenopyrite will probably be found at depth. The
walls are a mixture of slate and soapstone, but the hanging wall on
No. 2 Extension is porphyry. The vein strikes N. 15° W. to N. and to
N. 15° E., dips 53° E., and has a proven length on the surface of 6000'.

Operated with the Gold Bluff, which is also under bond to Grant
Snyder. A tramway is being built to transport Oxford ore to the
mill on the Gold Bluff.

A 150-light generator is installed to furnish electric light to mill,
boarding house and bunkhouse.

The Phoenix group contains 124.7 acres of patented claims, namely,
the Phoenix, Phoenix Millsite, Phoenix Extension No. 1 and No. 2,
West Extension No. 1, No. 2, No. 3 and No. 4, Phoenix East Extension,
No. 1 Millsite, and, besides these, five unpatented millsites, making
Jibout 150 acres in all. The lode is covered for a length of 9600'. It
is situated on the southeast and southwest slopes of Sierra Buttes.

The property was discovered by Mexicans in 1862. Later it was
owned by James Winstead, who took out $112,000, $44,000 of which
was from the West Extension. Next owned by Beard and Winstead,
and bought by A. C. Busch in 1889 from Beard for $27,000. Busch
took out $48,000 until 1891, since which time it has been in litigation.

The mine is developed by a 700' adit tunnel to the vein, with drifts
on the vein 450' west and 350' east. There is a 112' winze from drift
20' east of the adit, and a raise of 150' on the main shoot. Two old
shafts are both caved. One-half of the ground above the adit tunnel
level has been stoped, averaging $5.50 per ton, with limits of $8
and $4.

The vein is a quartz fissure carrying free gold, pyrite, galena and
ehalcopyrite. There is quartz gouge on both walls, the foot-wall being
blue diorite and the hanging wall porphyry. The width of the vein
is about 3^', and it strikes east, and dips 63° to 74° N. Three shoots
developed as follows: 125' by 3' wide, 50' by 3' and 84' by 3'; 1%
to 2% concentrates go $150 per ton.

Equipment consists of a 20-stamp Hendy mill, 20 years old, but in
good condition, and electrical machinery, moved to the Young
America mine, but still owned by the Phoenix.

The Plumbago property consists of eight quartz claims and one
.millsite, all patented, namely, the Hope (17.21 acres), Crofts (10.84
acres), Clute (17.21 acres). Gold Beater (12.72 acres), Standard
(13.22 acres), Standard Extension (19.25 acres). Enterprise (17.54
acres), Marion (20.36 acres) and Plumbago Millsite (3.64 acres), a
total of 132 acres. It is situated on the south side of the divide
between Kanaka Creek and the Middle Fork Yuba River.

Work has been carried on at intervals since before 1860, and the
production is said to have amounted to several millions. A total of
55 men were employed in 1915.

The mine is developed by a 200' crosscut tunnel, then 3800' of
drifting on the vein. This is called No. 4 or lower tunnel. At 2300'
from the portal there is a 330' winze with level No. 5, 113' below,
then 135' to No. 6, then 80' to No. 7. On No. 6 level 500' has been
drifted NW.-SE., on No. 6 drifts run 130' east and 460' west, and
between No. 6 and No. 7 a drift runs 210' west. At the northwest
end of No. 4 tunnel a break or split was encountered, the same as in
the upper levels.

The vein lies in a belt of amphibolite, between two bands of ser-
pentine less altered than usual. This belt is about 300' wide at the
widest part, but narrows to the northwest, where it passes under the
gravels which cap the ridge and wedges out again to the southwest.

SIERRA COUNTY. 113

The vein strikes N. 45° W., and dips 30° to 45° NE., sometimes 60°.
The quartz forms in lenses, varying from 1' to 12' in width, with rich
spots which seem to follow poorly marked shoots which have a south-
east pitch. The localization is considered to be due to an intersection
of -two veins. The quartz carries free gold in bunches. Outside of
the high grade the ore carries irregular amounts of sulphides, prin-
cipally pyrite, but including also galena, sphalerite and chalcopyrite.
Prom 1% to 2% of concentrates run $80 to $100 per ton.

Equipment consists of 2 Westinghouse generators, 180-h.p., 220 volt,
and 240-h.p., 220 volt ; two compressors, 550 cubic foot and 700 cubic
foot capacity, Norwalk and IngersoU, respectively, and a Ward drill
sharpener, houses, etc. The mill is equipped with a 20-stamp 850-lb.
Joshua Hendy battery and 4 Johnson concentrators. Mill and con-
centrating plant were destroyed by fire March 17, 1915, but a new
15-stamp battery and concentrators, arranged to facilitate th-i
addition of extra units, went into operation on July 5, 1915.

Water is obtained from Middle Fork Yuba River under 94' head
through 6000' of 34" redwood pipe. Transportation costs are $15
per ton from Nevada City.

[The mine was closed in the summer of 1918 and the manager's
absence made it impossible to get any new data. The winze is said
to have reached a depth of 800' below No. 4 tunnel, which is said to
be the limit attainable with the present hoist. Information regard-
ing reopening of the property is conflicting. — C. A. Logan.]

The Rainbow property consists of three claims, all patented, the
Farnham (12.6 acres). Groves (17.21 acres) and Hanley (20.64 acres),
covering a length along the lode of 4500'. It is situated on the steep
banks of Kanaka Creek.

The vein was discovered in 1885 in the course of gravel mining and
is said to have produced $1,500,000. There had been a 10-stamp mill
which was burned down in May, 1913, on the property. Leased for
six months to E. S. Brindle and Company, starting September 1, 1914.

114 MINES AND MINERAL RESOURCES.

The vein is developed by two tunnels. The lower one is a 1500'
crosscut to the vein, then on it for 700'. The upper tunnel, 500'
above lower tunnel, is 3000' in length. An upraise from the lower
connects with the upper tunnel.

Two veins have been developed to some extent. The smaller one
has an average strike of about N. 15° W., and dips 65° W.; the other
vein has a general strike of about N. 70° W., and dips 30° to 65°
north. The latter has furnished the gold yielded by the mine. The
quartz is milky white, generally between 1' and 2' wide, but in some
places reaches 5' or 6'. Intersecting veins enter from both foot and
hanging wall, but a band of gouge everywhere separates the inter-
secting vein from the main vein, indicating later movement parallel
to the strike. The ore occurs in small rich shoots, very rich masses
of free gold and arsenopyrite having been taken out around the edges
of the large mass of quartz found near the intersection of two veins.

There is an Ingersoll-Rand 12" x 14" single stage compressor on the
property. Both electricity and water are used for power. Water is
obtained from Kanaka Creek under 160' head.

The Sebastopol vein is developed by a 300' crosscut, which is driven
250' on the vein. The greatest depth reached below the outcrop is
90', and one raise 60' long is driven to the surface.

The deposit consists of quartz and altered country rock, carrying
free gold and less than 1% of sulphides. There is no well-defined
vein. The foot-wall is augite-porphyrite, altered near the vein, and
the hanging wall is said to be the same. The lode varies from 12' to
20' between walls and gold is stated to be found throughout. Its
strike is east, the dip 70° N., and it can be traced on the surface for
600'. One pay shoot 250' in length developed.

Equipment consists of cars and a blacksmith shop. A 5-stamp
Risdon mill is now being erected, the mill building being large enough
for 10 stamps. Five men were employed in 1914.

Water is obtainable from the Westphal Dam under 90' head.

Adjoining mines are the Round Lake quartz mine and the Westphal
placer claim. The latter has not been worked for the last five or
six years.

The Sherman property consists of one patented claim, the General
Sherman, 25 acres in area, and covering 2200' along the lode. H. G.
Ferguson has substantially the following to say regarding this
property :

"There is a tunnel 1000' long on the vein (100' below its outcrop). The main vein
is well defined for the first 700'. At 650' from the portal the tynnel encountered a
nearly horizontal quartz stringer, which has been followed for 450'. Beyond this It
pinches out, and only small discontinuous stringers of quartz are found to a point
within about 50' of the face, where a vein about 1' wide comes in.

The vein is sinuous, the strike varying between north and N. 30° W., and the dip
averaging about 60° W. The vein material is white quartz, slightly iron-stained.
In places it contains small inclusions of schist, and rarely small patches of pyrlte
associated with a little minutely crystalline arsenopyrite. Parallel to the walls are
streaks of gouge, containing pyrite."

The Sierra Alaska property embraces the following claims: The
Bates (11 acres), Spencer (11 acres), Phillips (9 acres). Grizzly (17.18
acres), all patented, and the Hog Eye (20.65 acres), New Alaska
Extension (20 acres). Parasite (20 acres) and Lonesome Cub (20
acres), unpatented, as well as two patented homesteads, making a
total of 480 acres. The Alaska lode is covered for a length of 4600',
and the Grizzly for 2600'. There is some timber on the property.

The lodes were discovered in 1863 in washing Texas Ravine. The
property has been sold to two different companies, and exploited in
London and Glasgow. It was sold to an English company, then
bought by present owners at a bankrupt sale in 1904. The total pro-
duction to date has been about $1,000,000 from 100,000 tons of ore.
Forty men were working in 1914.

The mine is developed by a vertical 3-compartment shaft, 900' deep.
At level No. 1, 120' below the collar, there is a drain tunnel 1300'
long; on level No. 2, 300' deep, is a drift 800' west on the Cassely
vein spur. On level No. 3, 450' deep, a drift runs 1500' east on the
Alaska vein, also a crosscut 62' west of the shaft runs to the Cassely.
Drifted on the Cassely for 400', then crosscut 200' to the Grizzly and
drifted 320' on the vein. At 550' (No. 4 level), crosscut 165' to the
Cassely, drifted on Cassely 235' west, crosscut 76' to the north, to the
Alaska vein and drifted on the latter 130' west and 1900' east. At
680' (No. 5 level), crosscut 64' to the Alaska vein and straight into
the northwest wall 266', then drifted west 200' and east 1500'. A
main winze being sunk 1325', was down 235' and drifting east and
west from the 115' level was in progress in 1914. The areas stoped
are very irregular.

Grizzly workings : No. 1 tunnel, 80' below surface, was run 200' on
the vein. The No. 2, starting in the drain tunnel of the Alaska, rims
770' on the vein. At 760' in, a raise now 100' up, is being driven to
the surface for ventilation.

The Alaska vein is characterized by lenses in serpentine. These
lenses are quartz, and calcite with quartz, carrying free leaf and
crystal gold. There is some ribbon rock. The vein averages 84'
' '^tween walls, while the quartz lenses have a maximum width of 16'.

SIERRA COUNTY. 119

As a rule the best values are in the enlarged part of vein, in true
lenses. The vein strikes N. 53° E., and dips 80° N. from the surface
to the 680' level, where it swings and at the 900' level it dips 45° S.
The Grizzly vein shows in line. Its walls are diabase, and the strike
is N. 78° E., the dip varying from 36° to 45° N.

It is necessary to pump 712,000 gallons per day from level No. 3,
using two Worthington 4-stage centrifugal pumps, 1000 gallons each,
against a 380' head. On No. 5 a Jamesville 150-h.p. turbine pumps
330,000 gallons to No. 3. On No. 4 a Byron Jackson 2-stage 50-h.p.
turbine pumps against a 100' head. A maximum of 1,500,000 gallons
per day is handled. There is also a 35-h.p. 3-stage 4" Albinger
pumping 300 gallons per minute against a 200' head.

Equipment consists of an 850 cubic foot 98-lb. compressor, made
with Regler valves, requiring 185 horsepower loaded, a machine shop,
lathe, drill press, blacksmith shop complete. Ward drill sharpener,
and a 2-drum, 75-h. p. General Electric hoist capable of 1500'.
Reduction equipment consists of a 40-stamp Joshua Hendy mill con-
taining 20 850-lb. stamps and 20 1050-lb. stamps, using 35-mesh
screens with high discharge, giving 92% amalgamated in the mortar.
The mill was erected in August, 1912, and also contains 6 Wilfley and
2 Deister tables. Water from the mine is used in the mill.

Power is obtained from thfe Pacific Gas and Electric Company at
440 volts. The total operating cost per ton is from $3.90 to $4;
wages were $2.75, $3 and $3.25. Transportation from Nevada City
costs $9 per ton. Reported idle in 1917.

The Sierra Buttes property consists of fifteen claims, six of which
are not patented, and includes the Independence quartz, Bigelow
quartz and millsite, Buttes Union quartz and Ariel quartz; also the
Oaks, Excelsior, Buttes and Packer placer claims. There is a total
of 660 acres, 360 of which is timber acreage. The property is situated
on the steep side of Sierra Buttes and covers a length of a mile and
a half along both veins.

Work was first begun on the mine in 1850. It was owned and
mined by an English company between 1870 and 1904 or 1905, when
it was purchased by Hayes, since which time it has been continuously
worked. The production by the English company was in the neigh-
borhood of $17,000,000.

120 MINES AND MINBRAI. RESOURCES.

Mining was being done in 1914 from the sixth level. On the ninth
level, 1200' northwest of the shaft, ore which averages $9 is 8aid to
have been encountered. A crosscut driven 400' into the hanging wall
tneountered a ledge which is probably one of the branches of the
Ariel vein. The No, 9 tunnel runs in from the level of the road at
Sierra City. 7200', to the Independence shaft, then 1350' to the end
of the drift. Of the 7200', 2000' is crosscut, the balance on the ledge.
The No. 6 level is 400' farther into the hill than the end of No. 9.
The main slope is the Mammoth, which follows down the Independ-
ence shaft. Stoped, at places, above the eighth level.

There are several veins in the property. The Ariel, also caJled
Independence, is the main one. The South Cliff is a branch vein from
the "Whiskey, which approaches the Ariel, but does not intersect it.
The Ariel branches into a number of different veins on the ninth level,
on which practically no prospecting has been done. The veins are
quartz fissures, carrying free gold, pyrite and a small amount of
galena and chalcopyrite. The Ariel is from 6' to 20' in width, the
f-trikc varying from N. 51" W. to S. 80° W. The dip is 54° N. The
foot-wall is greenstone and serpentine; the hanging wall quartz-
porphyry. Four pay shoots developed, the Mammoth being 300' long
and from 15' to 20' wide.

Mine equipment consists of a 2-stage compressor driven by water
power under 500' head, a blacksmith shop, 10 Ingersoll machine drills,
and boarding house. There are two mills, the lower one containing

-iO 900-!b. stamps erected in 1905 aud run by water caught at No. 8
level, 500' above. The ore is handled by tramway. The upper mill
is a 20-8tamp Pulton, 850-lb. stamps, with Challenge feeders. This
mill is at No. 5 level. Both mills were in running order in 1915. The
com pressor- house, part of stamp mill and other equipment was swept
away by a snowslide on January 9, 1916.

A ditch from Salmon and Sardine lakes delivers 300 inches of water
at No. 6 level under a i>00' head, a 1600' head abo^"^ the river.

The Sierra Standard Mining Company's property embraces two full
and three fractional mining claims, the Standard, Baker, Baker South
Extension, Standard Extension and Standard West Extension, having
a combined area of 80 acres and covering a length along the lode of
2010'. In general contour the surface is steep, and it contains some
timber.

The property was located by Tom Steel and Baker, who extracted
$28,000. It was purchased by the present owners from Crittenden in
1910. The total production to 1915 is said to be $75,000. Assessment
work only is being done at present.

Development consists of a 77' crosscut adit to the Big vein, then
along the vein 250' to its intersection with a cross-vein. It was
followed 100' beyond the intersection and then crosscut 60' to the
cross-vein. Drifted on cross-vein for 150' and then crosscut back
into the hanging wall for 100' to the Big vein. There are six tunnels,
from a few feet to 120' in length on the Big vein. A block 40' by
120' by from 5' to 8' was stoped on the cross-vein, producing $55,000.

The Big vein is quartz with gouge and talc in places near the con-
tact of serpentine and porphyry. The ore carries free gold and is
oxidized near the surface. The walls are porphyry, the distance
between walls being 14', and the average width of vein 4'. It strikes
N. 40° W., dips 50° to 60° E., and has a proven length on the surface
of 1500'. The production of this vein has been about $20,000. The
cross-vein carries free gold and arsenical pyrites. It crosses the for-
mation layers of black porphyry, strikes east, dips 45°, and is from
3' to 4' in width.

The mine is equipped with a 42 cubic foot 4^" x 4^" upright Duplex
air compressor. A 350' ditch delivers a minimum of 12 inches and a
maximum of 500 inches of water under a 125' head from Sailor
Ravine, averaging 200 inches for six months of the year.

The '16 to 1' property consists of two claims, both fractions, the
'16 to 1' and the Bagle, covering a length along the lode of 2200'. It
is situated on the steep slope between Alleghany and Kanaka Creek.

The property was located in 1908 by Lawson and Bradbury. Its
production is estimated by H. G. Ferguson to have been between
$150,000 and $300,000.

The main tunnel is a 125' crosscut to vein, then 900' on the vein.

124 MINES AND MINERAL RESOURCES.

A light 10-stamp mill, formerly in use at a mine near Washington,
was hauled to the Sixteen to One late in 1918, and was reported to be
ready for operation January 15, 1919. A new hoist has also been
installed.

The vein being mined has recently been the subject of a lawsuit
between this company and the Twenty-One Mining Company. The
latter company was said to be mining the downward extension of the
Sixteen to One's vein. In the suit the Twenty-One Company con-
tended that the vein was an extension of one outcropping within their
own surface boundaries. On the showing made in the underground
workings, judgment was awarded the Sixteen to One.

Finally, the Twenty-One Company brought suit to force the Sixteen
to One to confine mining operations on the Sixteen to One vein, under
the surface of the Twenty- One property, strictly to the area of the
vein as defined by the walls. This latter case had not been decided
in February, 1919.

The Sovereign mine consists of ten claims, a total of 200 acres,
covering a length along the lode of 4500'.

The Nevada vein is tapped by a 700' crosscut which gives 350' of
backs. From this point drifts have been run 150' north and 100'
south on the vein, and a raise of 60' put up. A 115' shaft has been
sunk on the Elanore vein, and a timnel 175' long has been driven on
the Yuba vein. A 400' crosscut had not reached the Yuba vein
in 1914. Practically no stoping has been done, the mine just having
been opened up. Six men were to be employed. The tailings, which
average $5, are leased to George E. Bigelow, Sierra City, who is
putting up a 25-ton cyanide plant.

The Nevada vein is a fissure vein cutting across the strike of the
slates, the ore running 3% pyrite and galena. Free gold averages
$1.50. It has a maximum thickness of 11', but averages 3', strikes
north, dips 60° W., and has a proven length on the surface of 4500'.
The Yuba vein carries free gold, with very little sulphides. It has a
width of 12', strikes N. 20° W. and dips 55°. The Elanore vein
carries free gold and has a width of 3', strikes N. 10° E. and dips
60° W.

Equipment consists of two 50- ton Beer's roller mills, 30-50 mesh,
and a 25-ton cyanide plant, agitated with air, 3 Overstrom concen-
trators, air compressor, drills, etc. A new compressor is being
installed. Water is carried in a 14" pipe under a 250' head from
Ladies Canon, giving a minimum of 85 horsepower at low water.

This property consists of seventeen and one-half claims, both
quartz and gravel, with a total area of 340 acres. It is situated on
a steep lava-covered ridge, and contains some timber. It was located
in 1889, and called the Telephone mine. The owner, Mitchell, took
out $500,000 from the gravel, it having averaged $50 to the car. A
company was formed in Chicago and purchased the property 12 years
ago. They advanced the purchase price $30,000, and also $15,000
additional, and a power house (40 horsepower) usin^ water from
the mine and melting snow, giving a minimum of 10-15 horsepower
and a maximum of 100 horsepower was built. It was worked for
four or five years when a quartz ledge was discovered, which was
drifted on 50' and stoped 30' to the lava capping above. A 5-stamp
mill was carried away by a snowslide, rebuilt, and again carried away
in 1907, after which the mine was closed down. It was reopened in
1908 to prospect for gravel.

The gravel claims of the Telegraph Company were bonded to Hunt
ajid Bell in June, 1915. There is no well-defined channel, but
apparently a series of benches.

The property has been developed by a 1500' tunnel, and two shafts,
one 65' deep not on the vein, and one 35' deep on the vein. The main
tunnel branches, one branch extending 500' north to an incline in the
old workings, the other running 800' east, where work will be recom-
menced. The main tunnel has been retimbered, and the compressor
and hoisting machinery have been overhauled and put in shape to
begin sinking on the vein at once.

Equipment consists of a 5-stamp Hendy mill with 750-lb. stamps,
concentrator and boarding houses, and a 180-gallon per minute
centrifugal pump.

Adjoining mines are the Hilo and Monte Cristo.

Serious damage to buildings and machinery by fire and snowslides
compelled suspension of active quartz development.

drawn largely from Bulletin 580 1, U. S. Geol. Survey, by H. Q.
Ferguson ;

The Tightner vein was rediscovered by H. L. Johnson in 1907,
During the placer operations of early days the vein had been cut in
a bedrock tunnel, but no attention was then paid to it. Mr. Johnson,
interested by stories of old-timers regarding rich quartz gold,
reopened the old tunnel and is reported to have taken out nearly
$500,000 in gold. The present company began operations in 1911
and has developed the vein on the lower level. The production under
the present management had been about $600,000 up to Jane, 1913.

The upper tunnel (elevation 4495.8') was driven in from the ravine,
30' below the hotel, and at a distance of 650' encountered the vein.
A number of tons of very rich ore were taken out, and several other
rich bunches were discovered in drifting and sinking. A fault, slip

128 MINES AND MINERAL RESOURCES.

J 00' vertical and 300' horizontal, was encountered in sinking, and the
vein was lost. A lower tunnel was started from the North Fork of
Kanaka Creek, one-half mile below the town on the Eclipse claim, at
an elevation of 4082.5'. It was driven in a northwest direction
through the hanging wall of the vein for a distance of 1265', where a
crossing was encountered with talc gouge and quartz stringers. A
drift was started N. 30° W. on this formation, and at a distance of
350' north of crosscut intersected the main vein striking north.

The Tightner vein is a fissure vein in schist, altered near the vein
and slips to talcose or chloritic schist. Hydrothermal alteration is
common, but irregular. Masses of dolomite and mariposile are
irregularly distributed along the walls, and in places there is silicifi-
cation as well. The vein crosses the steeply dipping laminae of the
schist, but the schist is so sheared and altered near the walls that
the difference in dip between the vein and the schist can only rarely
be observed. The fissure vein, which is faulted by a vertical slip 100'
and horizontal 300', has a well-defined black clay gouge on the fault
wall, showing striations raking 73° to the north from horizontal.
The principal values are in rich * specimen' gold, which occurs in
'rich bunches' in poorly defined ore shoots. Arsenopyrite carrying
large amounts of free gold makes up the rich ore. The foot-wall is
amphibolite schist, altered schist, talcose, etc. The hanging wall is
soft and heavy talc, chloritic schist and serpentine. The maximum
width of the vein is 20', the average from 3' to 5'. Its strike varies
in different parts through an angle of 45°, around north. The dip
\aries from 30° to 55° E. The rich ore taken from the lower work-
ings has come from two areas, one just south of the winze connecting
the upper and lower workings and the other about 700' north of the
winze. At each place the vein is wider than the average, its width
being about 7' at one place and 10' at the other ; moreover, they both
lie at the north ends of marked enlargements of the vein and at
nearly equal distances, about 100', north of intersecting veins. In
March, 1916, the long crosscut from the lower adit intersected the
Osceola vein, disclosing medium grade ore. Crosscutting was being
continued to reach the Red Star ledge, which yielded bonanza in the
upper workings.

Milling is done with mine water. The 10-stamp mill is running
steadily. About 100 men were employed in the summer of 1915.

The mine and mill were being operated with a small force of men
in September, 1918. The lower levels of the mine have been tempo-
rarily abandoned, but some stoping was being done above the main
working tunnel.

SIERRA COUNTY. 129

The Tightner vein has been prospected for 1200' on the strike and
for 800' on the horizontal projection of the dip, the winze having
reached an inclined depth of 340' below the upper (main) level. The
main tunnel has been driven north 6500' under the Red Star claim
without developing much rich ore. There is an unprospected vein
varying in width from 6" to 30' on the Contact Extension claim.

Where the ore was low grade, pillars were left and no timber was
used; in good ore, stulls and headboards were put in. An electric
hoist at the top of the winze brought the ore from the lower levels
and it was hauled thence to the mill by mules. Mining costs about
$4 a ton. Only about 15 men were employed in September, 1918, and
it was said to be nearly impossible to get miners.

It was found that the galena in the concentrate carried about $100
a ton, while the pyrite was worth only about $40 a ton. On account
of the lack of any plant nearby for treating the sulphides, and the
high cost of hauling to the railroad ($20 a ton being the rate to
Nevada City) a differential concentration was being made in 1915.
The galena was saved on two Deister tables and the pyrite was run
to waste. This plan was abandoned soon, and lately all the sulphides
have been saved and stored. Two new batteries of five heavy stamps
each on concrete foundations were running in 1915, giving a total of
20 stamps with a capacity of about 2700 tons a month. Cost of treat-
ment was said to be about $1 a ton. Besides $470,000 produced
during the Johnson regime, the present company reports a yield of
$1,526,000 to the end of 1917.

Tightner Mine Dump. Owner, Tightner Mines Company. Leased
to R. L. Hathaway and W. H. Martin, of Nevada City. The lessees
erected a battery of five 850-lb. stamps in 1916. The rock milled was
the dump thrown out during H. L. Johnson's regime. The mill was
in operation from September 12, 1916, to September 1, 1917. It was
run by electric power and plain amalgamation only was used. Prob-
ably somewhat over 5000 tons were milled and it is said locally that
a handsome profit was realized.

The Tomboy Eureka property consists of two unpatented claims,
the Tomboy and the Tomboy Extension, having an area of 40 acres,
which covers a length along the lode of 3000', and the Eureka, a
N.-S. claim along the serpentine contact. The property was located
35 years ago, and relocated 20 years later by A. M. Bixby. The out-
put to date has been between $4000 and $5000.

130 MINES AND MINERAL RESOURCES.

The Tomboy vein is developed by a tunnel 12' crosscut and 200'
driven on the vein. Another tunnel 50' below is a 240' crosscut, then
140' on the vein ; 310' in from the mouth of the lower tunnel, there is
a raise on an ore shoot. The Eureka vein is opened up by a 200'
crosscut, and 100' on the vein.

The Tomboy vein is quartz and porphyry, carrying free gold, a
little arsenopyrite and pyrite, with porphyry walls. It varies from
6" to 7' in width, strikes east, and dips 60° S. The Eureka vein
varies from 3" to 3' in width, strikes north, and has a flat dip to the
east. The ore is in lenses of quartz which carry principally arseno-
pyrite.

Equipment consists of a cabin, blacksmith shop, tools, etc. Elec-
tricity is transmitted a distance of 1500' and used for power.

The Twenty-One property contains four claims, the Twenty-One,
Belmont, Valentine and Tightner Extension, a total of 60 acres cover-
ing 2400' along the lode. It is situated on the steep rise from Kitnaka
Creek to Alleghany. The production from early day pocket mining
to date has been about $100,000. The North American Exploration
Company surrendered their bond in February, 1915, and the property
was taken over by G. W. Mitchell and associates of Sacramento.

There are two veins, the * 16 to 1' and the Tightner. The former is
a quartz and talcose schist fissure vein, carrying free gold and arseno-
pyrite, with walls of schist. It strikes N. 40° W. and dips northeast
from 45° to vertical. The Tightner vein pinches and swells greatly,
quartz being absent for considerable distances. Although at a lower

SIERRA COUNTY. 131

level than neighboring mines, there appears (according to H. G.
Ferguson) to be more oxidation, and secondary pyrite is said to be
prominent. The walls are schist, and the strike varies from N. 10°
to 50° W., the dip being from 30° to 50°.

Development work consists of an old shaft 165' deep, now full of
water. A tunnel was driven 500' on the '16 to 1' vein from Kanaka
Creek, then crosscut 155' northeast to the Tightner vein, which was
drifted on for 1400', giving 900' of backs. At a point 350' from the
face of the drift on the Tightner vein a 90' raise was driven. An inter-
mediate drift was started at the top and some stoping has been done
from this raise. Three shoots have been developed as follows: 120'
north of the crosscut a shoot 120' long, 2' wide, averaging $7; 580'
north a second shoot 240' long by 3^' wide, averaging $10; and
1020' north a third shoot, 300' long by 4' wide, averaging $11.

There is a blacksmith shop on the property and a mill with 10
stamps. Lane mill and Frue vanners are being installed. Electric
power is obtained from the Middle Yuba Power Company.

Ten men were w^orking in 1914.

The Tightner mine adjoins this prospect on the northwest.

Late in 1918 the company was involved in a lawsuit with the Six-
teen to One, in which judgment in the sum of $100,000 was awarded
the latter, because of alleged invasion of the Sixteen to One vein.

The Uncle Sam property consists of the Uncle Sam and the Uncle
Sam Extension placer claims, and the Simpson (1500' by 420'),
Verrue (1500' by 420'), Yates (1500' by 220'), and Keller (1500' by
220'), claims covering 3000' of the ledge discovered in working the
gravels.

The ground was worked in early days for gravel, and $100,000 was
taken out. Stone began work on the ledge in 1910, and it has been
developed by a 1037' inclined shaft (14°) through lava into the
channel. A 700' crosscut runs to the west rim, from which point a
55° inclined shaft, 75' to the first level and 100' to the second,

the wall 100', and crosscut of 90', picked up a ledge dipping 60^ NE.
On No. 2 level a 60' crosscut has been run into the hanging wall.

A winze sunk in April, 1915, intersected an ore body 5' wide,
showing gold and arsenical sulphides. A marked change in the vein
occurred after passing water levels and the ore is the most peculiar
ever found in the district. Extending to a point about 30' below
water level the vein contained considerable iron sulphurets, some
gold and traces of silver. Further down the sulphurets are displaced
by arsenical minerals with a higher gold content and a rapid increase
in silver values. In 1914 the ore was said to carry practically equal
values in gold and silver, marking the first time in the history of the
district that silver in important percentages has appeared.

The ore occurs in quartz lenses carrying free gold, arsenopyrite,
pyrite and marcasite. The foot-wall is chloritic schist and black
coal,(?) the hanging wall is a hard diorite. The vein varies from 2'
to 18' in width, strikes N. 20° W., and dips 80° SB. It is estimated
that 2000 tons of $7 ore is exposed, and the erection of a 5-stamp mill
is contemplated.

Equipment consists of a blacksmith shop, 10-h.p. electric hoist,
12"x 12" compressor and machine drills. Electricity is used for
power.

There were eight men employed in 1914.

It is an old mine, discovered by Willowby. In 1906 it was worked
by Roddy, who purchased it for $20,000 from Pete Lorenzi, of Johns-
ville. Roddy sold it to the present owners in 1909.

The development works consists of two tunnels, one 566' long, part
crosscut, and a lower one 700' long, part crosscut. Some stoping has
been done on the front ledge. The back ledge is not cut by either
tunnel, but ore was being taken in 1915 from a shaft, then 20' deep,
which was being sunk on the back ledge.

There are two parallel veins from 75' to 100' apart, both quartz
fissure veins containing free gold, pyrite and galena. The strike is
north, and the dip 60° W., between a foot-wall of slate and hanging
wall of porphyry. Ore averaging $40 per ton was being taken out
in June, 1915.

Equipment consists of an old 10-stamp Union Iron Works mill,
900-lb. stamps, and two concentrators, remodeled, and run by steam.
There is also a boarding house, blacksmith shop and office. Four men
are employed at present.

Adjoining mines are the Oakland and Empire.

The York mine is located on the AUeghany-Downieville belt of
serpentine, adjoining the townsite of Downieville on the south. It
has yielded over $75,000 in bonanza ore that required no milling, from
a shaft less than 100' deep, and was to be reopened in the summer of

1915 under bond and optioij by a Sacramento company. Early in

1916 preparations were under way for the unwatering of the old
100' shaft preparatory to further sinking. All materials were on
hand, and the work of repairing the power line was in progress.
Geo. B. Morse is in charge.

The Tinney Mines, Incorporated, of 825 Tenth street, Sacramento,
was incorporated May 1, 1916, to take over the option.
