COLORADO.

This Company is formed for the purpose of acquiring and
working valuable mineral properties situated at the head
of Geneva Valley.

Geneva Valley is sixty-four miles from Denver, and opens
on to the north fork of the Platte Valley at Grant, where
there is a station on the Denver and South Park Eailway.

The property is composed of a number of mines and min-
ing claims, including the well-known Revenue lode, which
crops out and crosses the continental water-shed. This
mine, together with the group of lodes below it on the At-
lantic slope, came into the possession of the parties owning
the Britannic tunnel, and those owning the Leviathan tun-
nel, several years ago. Acting under the advice of mining
experts, it was decided to suspend active working from the
surface, and to prove the lodes by tunneling from the moun-
tain side. Accordingly, the two tunnels were started about
one thousand feet apart. The Britannic tunnel cutting, in
its course of 1,025 feet, no fewer than fourteen silver and
gold-bearing lodes, and the Leviathan intersecting, in 800
feet, 13 lodes, which are undoubtedly extensions of the
former ; together they may well be called the Geneva Group.
Little more has been done upon these lodes than to prove

their value, but sufficient has been accomplished to dem-
onstrate their vast paying capacity when fully devel-
oped, and also to continue and increase their present ore
producing capacity.

The surface claims are ihe Ee venue, Baltic, Celtic, Repub-
lic, Oceanic, Gaelic, Adriatic, Murphy, Hugh Kelley, Best,
Dudley, Blue, Little Eailroad and the Kelly & Dudley
lodes, for all of which United States Government patents
have been issued, also the Jurassic, Japanic, Occidental and
Graphic — all secured in accordance with the United States
mining laws, and embracing with the tunnel rights an
immense mining territory.

Included in the purchase is the property embraced in the
following inventory :

This Company takes all the ore broken at the mines,
estimated at 300 tons, and slag at the smelting works, about
300 tons.

.The mines have been reported upon by several mining
engineers and experts, under whose advice the improve-
ments and developments have been made. Formerly, Mr.
E. 0. Old, M. E., of Georgetown, was employed by the then
owners of the Eevenue, and in a careful report gave an un-
hesitating opinion of the great value of this mine and of
the merits of the other claims. Later, Mr. Thos. Belt, F.
G. S. M. E., of London, England, examined the Eevenue
and other property as far as then opened, and advised push-
ing the Britannic tunnel in preference to working from the
surface, concluding his report as follows: "Altogether, I
consider the Eevenue mine, both as regards its production
of valuable ore and the great advantages the district offers
for the erection ot reduction works, the most promising un-
dertaking that came under my notice in Colorado, and am
satisfied that if judiciously managed will yield enormous
profits."

The lodes in the Leviathan tunnel have not been ex-
plored as much as they have been in the Britannic, but as
in most instances they will be found to be continuations of
the veins cut in the Britannic tunnel, the report and de-
scriptions apply generally to the whole property. A record
is attached of some mill runs and samples.

The extensive forests in Geneva Valley are becoming
valuable, and are practically under the control of this com-

pany. Lumber is being shipped to Denver from a point
twelve miles below Grant, and accessible timber is becom-
ing daily more scarce. Rough Colorado lumber is worth
in Denver $22.50 per 1,000 feet ; the freight from Grant
would be about four dollars per thousand, leaving a wide
margin for profit.

Taken altogether, the combined interests present one of
the most perfect and extensive mining properties in Amer-
ica. Some of the directors visited the mines in October,
and have every confidence, that after carrying out some fur-
ther improvements, that the mines will be at once placed
in a paying condition. They satisfied themselves thoroughly
in respect to titles, and the correctness of the extracts and
reports attached hereto, and have no hesitation in recom-
mending the enterprise as one of the soundest and most
promising mining investments in Colorado.

According to purchase this company takes possession of
the properties free from all debts or other encumbrances.

WASHINGTON, D. C., October Zbth, 1883.

To the Board of Directors of " The Geneva Grey Copper,
Silver and Gold Mining and Milling Company :"

Gentlemen : —

Having visited the mining property known as the Geneva
property, situated at the head of Geneva Gulch, in Clear
Creek, Park and Summit Counties, in the State of Colo-
rado, and personally examined the same for my own satis-
faction and that of others, lor the purpose of ascertaining
its value, beg leave to submit the following report, which
is substantially a copy of a report made by me to Hon. B.
F. Jonas and Gen. John A. Logan.

First. I submit the following copies of letters and pa-
pers relating to this property, namely — 1st. Letter of
George Teal, a mining Engineer of Boulder, Colorado ;
2nd. Let;er of Hon. J. B. Grant, Governor of that State;
3rd. Letter of Geo. Rust & Co., owners of a recently con-
structed Concentration works at Decatur, Colorado, and
4th. A letter of A. A. Egbert, the General Superintendent
of the Colorado division of the Union Pacific Railroad
Company.

These letters explain themselves.

Second. The result of my personal examination of these
mines, and the property belonging to them. To begin
that, I call your attention to the printed report made to
Jno. W. Godfrey, by A. W. Kellogg, (copy herewith en-
closed). This report, as to the amount and character of
developemnt-work done in the mines, I found substantially
correct. In making my examinations of the property, I
explored all the tunnels, shafts and levels or drifts, cut and
sunk. There are three tunnels, namely, — the "Britannic,"
the "Leviathan," and the "Mallory." The " Britannica"
has been run into the mountain (the main divide of the
Rocky Mountains, a distance of about 1050 feet from the
Atlantic side, and within about 300 feet of the Pacific
slope.) The " Leviathan" a distance of about 750 feet,
and the " Mallory" about 400 feet. The " Leviathan" cuts
two veins; one of which has some developement-work
done The " Britannic, " or principal tunnel, cuts three
good silver veins, the " Celtic," the " Baltic," and the
" Revenue." It cuts the " Celtic" lode at about 400 feet

in the Mountain, the "Baltic" at about 750 feet, and the
"Kevenue" near its present terminus. On the "Celtic"
vein or lode, a drift has been run a distance of near 200
feet, passing in its course the shaft sunk on that vein from
the surface, thus furnishing good ventilation of the tunnel
at that point. On thj " Baltic" vein or lode, the principal
work of ore developement has been done; at the point
where the "Britannic" tunnel cuts or crosses this vein, a
shaft has been sunk, on the vein, to the depth of 240 feet.
From which shaft, at intervals of each 60 feet in its down-
ward course, drifts have been been run, on the vein, dis-
tances averaging about 100 feet each, thus exposing,
ready for mining, the vein 60 by 100 feet for each 60 feet
thus run. This is what is called in mining p.rlance
" Blocks, or 01 e in sight." There are four of these "blocks"
opened and developed in this 240 feet shaft. In my meas-
urement of this vein, in this shaft and in the different drifts
run from it, I make the average thickness 16 inches. The
thinest point I found being 8 inches, and running from that
to 23 inches. But allowing the vein to average only 12
inches, then we find that there is ore in these four blocks, (60
by 100 feet each), 24,000 cubic feet, and allowing 10 cubic
feet to the ton there is 2,400 tons of ore ready to be taken
out for market from this devlopement alone. The assays
I had made from ore that I took from this vein, in person,
excluding the largest, " No. 6," shows an average of $118.-
28 per ton. In obtaining the samples, I cut the vein at
various points in the shaft and dirifts, and, in doing so, I
took the ore in each case from clear across the vein, in or-
der to secure an average quality of the vein. These sam-
ples I took personal charge of and took them to Denver
to be assayed, and before having the assays made, I made
inquiry of the oldest and most reputable citizens of that
place, Governor Grant among the number, to ascertain who
was the reliable assayist there, and was unanimously re-
commended to rely upon Prof. E. B. Burlingame. I then
committed my samples to him to assay. His certificate
thereof was mailed to you at New Orleans, also a copy
thereof to Gen. John A. Logan at Chicago. In regard to
these assays I will explain that I did not intend the large
assay " No. 6 " should be included with the other eight in
making the average assay of the lode. After I had pro-
cured the samples I did, for that purpose, I then, with the

mining engineer, looked through the vein to try and find
the richest specimen we could, and selected the " Bismuth"
specimen, from which assay " No. 6 " was made. But,
excluding that, the average of the remaining eight shows a
value far above what is now considered valuable mining ore.
The best informed men T found said to me that ore which
would run $60 per ton, with reasonably moderate transpor-
tation, would pay well. On the subject of the market for
the ore of these mines and the transportation thereof, I will
say that, with the main tunnel, (the Britannic,) being com-
pletely through the mountain to the Pacific slope, a dis-
tance of only about 300 feet from its present terminus,
brings that end of the tunnel to within about two miles of
the town of Decatur, situated immediately below that point,
in the valley ot a tributary of Snake River, where the
Concentration (works) mill of Geo. Rust & and Co. is now-
operating, and, by the construction of a suitable tramway,
the ore can be transported from the Pacific end of the tun-
nel to that point automatically. Besides this, I have the
assurance of the General Superintendent of the Colorado
Division of the U. P. K K., that its South Park branch,
now within ten miles of Decatur, will be extended to that
point early next spring (see his letter). With these facili-
ties, all the ore of these mines, (both high and low grades),
can be available conveniently and at a large profit. In ad-
dition to the ore development, above mentioned, there is
now out of the mines, and on the ore dumps at the Atlan-
tic ends of these tunnels, about 300 hundred tons of low
grade ore, that is to say, ore taken from the mine in mak-
ing these developements, from which the richest parts have
been culled and carted or packed to market. This low
grade assay $51.07 per ton. (See assay No. -5.) Hitherto
all ore taken from these mines had to be taken to " Grant,"
a station on the South Park Railroad, distant 12 miles from
the mines. Consequently, this low grade ore was not and
could not be made available. But with the " Britannic "
tunnel completed it can be made available at a good profit.
There are embraced in this property, nine well defined
fissure- veins or lodes, all in one group, the titles to which
are perfect; beginning with the United States patents, and
coining down to the present owners, in one unbroken line.
Besides these lodes, there is a large amount of other prop-
erty, consisting of timber lands, and milling sites, all with
like titles. Also, a large amount of machinery and tools,

10

consisting of one heat concentrator ; steam saw mill, in
complete order ; one 35-horse power engine, in the mines,
complete ; a complete assay office and apparatus ; black-
smith shops snd tools of all kinds, nearly.

The tunnels referred to are all well constructed, and in
excellent working condition; their sizes are about 6 feet in
width, and from 6J to 7J in height, The shafts and drifts
are all large and roomy and all in good working condi-
tion. There is no water encountered in any of them. In-
deed the attitude of these works is so great (about 11,000
feet) that no danger of being interferred with by water need
ever be apprehended. From the cost of tunnelling and
shafting at the present time, with the modern appliances
therefor, the work of this character already done in these
mines could not now be done for anything near the price
for which this property has been purchased, namely,
$200,000. So that, on the plan proposed to operate it the
only question that need be considered by those engaging in
the enterprise and furnishing the $30,000 in cash to be
placed in the treasury of the company, as a fund to defray
the necessary expenses and to push the " Brittanic" tunnel
through to the Pacific slope, and to construct a tramway to
transport the ore to the mill or railway at Decatur, by the
time next spring when the railroad reaches that point, is
whether the quantity and quality of the ore in the several
veins developed and belonging to the property will justify
the investment.

On that subject I have no hesitancy in saying that, from
my personal examination, I am satisfied that the ore al-
ready developed in the "Baltic" vein, with the low grade
ore above referred to as already out, is vastly more than
sufficient to cover the $30,000 and provide for the interest
on the $200,000 of the bonds of the company, at 6 per cent,
per annum, given in payment for the entire property; and
also to make all necessary developments and improvements
for the further operation of the mines in the future. If I
am correct in this, then those who furnish that operating
capital, will be secure in being reimbursed the amount con-
tributed to that fund within the first year, and have the in-
terest represented by their stock in any future there may
be in property, without any cost, beyond the use, for that
time of the sum thus advanced to start the enterprise. As
I presume you are not acquainted with the history of the

11

property, and its operation in the past, I deem it proper
to explain that, as I learned it in Colorado from those who
have known it from its first discovery, these mines were
originally owned, partly by a company, and partly by individ
uals. Upon the development of these several lodes in the
beginning, it was found from their "dips," that they were
running together at no great distance down ; therefore the
company, and the several individual claimants consolidated
their interests, and organized what was known as " The
Geneva Consolidated Mining and Smelting Company." The
business affairs of this company was committed to the man-
agement of a man who proved extravagant and careless, and,
before the stockholders found it out, involved the company
largely in debt; to provide for the payment of which the
company borrowed money and secured that loan by a trust
deed on the entire property. The company failing to pay
the first interest thereon, the trust was executed, the prop-
erty sold and purchased by the cestue que trust, who sold to
this new company. This is the explanation why such an
amount ot valuable development-work on good veins of ore
is made obtainable at the price of $200,000, payable in the
bonds of this company, due in ten years, bearing interest at
6 per cent, per annum, payable semi-annually, with the
privilege of the company paying the whole or any part
thereof at any time after one year, if it desires to do so.
These bondssecured by a first mortgage on the property only .

The basis of my estimates upon which I express)the opin-
ion that there can be no risk in embarking in the enterprise
proposed is : that allowing the ore in " Blocks " to be 2,400
tons, which assays §113.28 per ton, I reduce that assay to
$100 per ton, then allow the large cost of one-half for tak-
ing that ore out of the " Blocks," and milling the same,
still there would be a net value thereof of $120,000 besides
the avails of 300 tons of low grade ore now out.

In conclusion, I will add that, so well am I satisfied with
the property, after a thorough personal examination of the
same, and its future, that I shall take one of the six inter-
ests to furnish the $30.000, on the plan proposed by Gen.
Simmes, in the formation of the new company, which I
suppose he has fully acquainted you with, and I shall not
hesitate to advise any of my friends, who may be able to
do so, to do likewise.

Yery respectfully, &c.,

(Signed) W. W. WILSHIRE.

BOULDER, COLORADO, October 13, 1883.
W. W. WILSHIRE Esq.:

DEAR SIR : Yours of to-day to hand, and in reply will
say, 1st. I do regard the property valuable, and one, had I
means, would cheerfully invest in. I also feel satisfied that
with proper management^ both in regard to the working of
the mine and the treatment of the ore, the mine can and
will pay largely.

Its past management is no secret; in fact, it has been
well known as the mine of the forty thieves. Therefore,
it is not to be wondered at why so much money has been
expended, and so little returns.

2d. The mine can be worked all the year without any
extra cost or danger. The snow does not affect the devel-
opment ot the property. Some winters the roads are bet-
ter for travel from the mines to the railroad, owing to the
good sleighing.

Yours, most respectfully,

GEORGE TEAL,

Mining Engineer.

Indorsed as follows:

I regard Mr. George Teal as one of our most able and
reliable mining engineers in Colorado.

I know Mr. Teal; he is a good mining engineer ; has
been in the management of large mines. I have no doubt
about his statements being correct.

DEAR SIR : In reply to your inquiry as to the reputation
of Mr. E. E. Burlingame as an assay er, I am happy to say

DENVER, COLORADO, October 15, 1883.
Mr. W. W. WILSHIRE:

DEAR SIR: You ask me the character of my reduction
works at Decatur, &c. It is for treating copper and zinc
or antimony ores, or such ores as are considered refractory.
Can use lead ore that does not run more than 10 per cent,
in lead, but do not pay anything for it, as we cannot at
present save lead; but in the course of a year we expect to
add a smelter to our plant. Our plant is complete, and
the first run has been made and is a great success. We
can handle at present about ten tons per day, but by the ad-
dition of an automatic roaster can increase with our present
capacity to 30 tons. We are running on Montezuma ores
at present, which they have to bring eight miles up the
valley.

We expect the railroad in soon, when we will be the
natural centre for all ores in that region.
Very truly yours,

ON THE

Geneva Mining Estate.

DENVER, COL., January 1, 1882.

DEAR SIR : In accordance with your request, I herewith
submit my report on the " Geneva Mining Estate :"

LOCATION, ETC.

It is situated in Clear Creek and Park counties in Colo-
rado, about seventy miles from Denver, and consists of nine-
teen lode claims on Ke venue Mountain, at the head of
Geneva Creek, the tributary of the Platte Eiver ; of four
mill sites on said creek; of 480 acres of timber and agricul-
tural land at Grant, a station on the D., S. P. & P. Railroad,
located at the mouth of Geneva Creek ; of a smelter, saw
mill, offices, etc., at Asterville, about eight miles from Grant,
on said creek, and of boarding houses, machinery, and
mining buildings at the mines.

LODE CLAIMS.

These claims are known as the Revenue, Baltic, Celtic,
Republic, Oceanic, Adriatic, Gaelic, Graphic, Belgic, Blue,
Best, (for all of which Government patents have been issued,)
Japanic, Occidental, Murphy, Hugh Kelley, Dudley, Little
Railroad, and Kelley and Dudley. These latter are distinct
claims, but covered and protected by the surface lines of the
patented claims.

HISTORY.

The discovery of good surface ore (float) on Revenue
Mountain, in 1873, induced several prospectors to com-
mence work at that point, and a large number of locations
were soon made. The result of further work was the pro-

16

duction and shipment of fair quantities of high-grade pay
ores; some of it of such exceptional richness as to attract
the attention of investors, who, with a view of opening the
claims at greater depths, purchased several of them, pro-
jected and drove the Leviathan tunnel. The company op-
erating this tunnel also purchased quite a number of the
adjoining surface locations, and did some valuable prospect-
ing work by sinking shafts and running cross-cuts thereon,
while driving their main tunnel a distance of 764 feet into
the mountain, cutting several veins at a good depth, but not
securing any large quantity of pay ore except from the
second vein cut. One of the properties which attracted
much attention, by reason of its rich surface ores, was the
Eevenue mine. This property was purchased for a large
consideration from the original discoverers, and soon passed
into the hands of English capitalists, who organized the
Revenue Mining Company, by whom the work was prose-
cuted and large shipments of rich ore made. Other prop-
erties were acquired by this company, and, after some time,
a conflict of title arising with the Leviathan Tunnel Com-
pany, a consolidation of property and interests was effected,
and the Geneva Consolidated Mining and Smelting Com-
pany was organized, with a capitalization of two million
five hundred thousand ($2,500,000) dollars. By this con-
solidation of interests the new company was well situated
for good and effective work. Possessed of an immense
mineral territory, with fissue-veins, mill, and tunnel rights
of assured value, this company should have made a great
success, and have added largely to the world's store of
precious metals at a profit. That these results were not at-
tained is to be regretted, but must not be charged against
the property. An elaborate system of development was
inaugurated and carried on until, by reason of lavish ex-
penditure and mismanagement, the credit of the company
was exhausted and its property sold to meet the demand of
creditors. The mine development thus obtained, at a loss
to stockholders, is all of value to future owners. The ex-
penditure for the erection of the smelter may be considered
as nearly a total loss, as it is of no practical value to the
estate.

This enterprise was but a repetition of the mistake so
often made by mining companies who, when operating at
a distance from suitable ore markets, seek to lessen their
freight charges by endeavoring to successfully treat their

17

own refractory ores, and this in total disregard of the fact
that such ores of one class only can not he smelted econom-
ically; that a variety of ores, not usually obtainable from
any one mine, must be had to secure a proper flux and such
a profit as will warrant the expense of plant and treatment.
The only works needed with this property is a concentrating
mill, and that only when a large quantity of low grades
shall have accumulated.

Stopes have also been driven to the amount of 650 fathoms.
I estimate, roughly, the proper cost of the above work at
$120,000. The erection of smelter, saw mill, buildings, ma-
chinery, etc., will make another item of a least $200,000. I

18

am informed, however, that under the system of manage-
ment adopted, the outlay has been over $500,000. From
the best information I can obtain, the property has pro-
duced between $150,000 and $200,000.

In the early history of the mines, much of the work was
done by lessees, and large quantities of high grade ore were
stolen and never accounted for. It has lately transpired
that ore was regularly transported to Georgetown, a distance
of fourteen miles, by night, from which the company never
realized a dollar, and of which we are unable to get any
returns as to quantity and value. The ore must have been
high grade, in order to stand such high freight and treating
charges as would be demanded under the circumstances. In
many instances, also, sampling works, where the company
marketed their ores, have changed hands, and the books of
the previous owners can not be obtained from which to se-
cure accurate returns. I append copies of returns from the
Boston and Colorado Smelting Company, showing ship-
ments to them which aggregate over $38,000. My estimate
of total production is made from what I know of the ore
at present, and from what I can indirectly learn from
parties familiar with the character of the ore bodies in
the past.

My attention was called to the property in Jul v last, when
I was shown a list of assays made by Professor Burlingame,
of this city, (a copy of which is appended and marked Ex-
hibit B.) They gave such a fine average that I was induced
to examine the property, with a view to its future possibil-
ities. At that time I took forty- two samples of ore from
the various workings, many of these samples being assayed
from curiosity only, but resulting in another large average,
as shown in Exhibit C, hereto attached. Since that time I
have had the general management of the work and have
carefully examined the property, making frequent tests of
the ore, and with uniformly large results, so much so that
I am surprised at the quantity of the ore and its exceptional
value. From these tests and my familiarity with the work-
ings I am, therefore, to a certain extent, qualified to esti-
mate the probable value of the ore already extracted.

In sinking and in driving the levels and stops, nearly 4,000
tons of ore should have been extracted, worth in the rough
at least $50 per ton. This would give an aggregate yield
of nearly $200,000, as indicated above, though it may not
have reached that amount.

19

CHARACTER OF THE ORES.

The ores of this district are mainly argentiferous, galena,
and bismuth, iron and copper pyrites, gray copper, and zinc
blend. Ruby, brittle, and native silver are also found, and
nearly all of these ores carry a small percentage of gold.

TREATMENT OF THE ORES.

At present the most available manner of realizing from
these ores is to rough dress them by hand, and ship to
smelters all ores running $75 per ton and upward. Ore of
this class in quantity will pay handsomely, and the facilities
for marketing them are increasing every year. Plans are
now being considered for the erection in various portions of
the State of leaching works similiar to those used in Cal-
ifornia whereby pyrites ores can be handled at a much less
cost than by smelting. If this be done, the Geneva ores
should be submitted to a different dressing and three classes
made, viz: smelting ore — galena, gray copper, and bismuth;
chlorination ore — iron and copper pyrites; concentration
ore — all ore of too low grade for profitable shipment.

FUTURE WORK.

In regard to the future working and development of this
great property, I suggest--

1st. The completion of the Britannic tunnel through to
the Pacific slope, a distance of 300 feet.

2d. Tne completion of the upraise on the Revenue vein
until a junction is made with the main or working shaft.

3d. The extension of the Mallory tunnel to a junction
with the blue lode.

4th. The extension of the West tunnel level on the Bal-
tic vein to a junction with a drift from the Mallory tunnel
on the same vein.

5th. The projection and driving of a lower or main tun-
nel at least 600 feet deeper than the Britannic tunnel and
from the lowest available point on the Pacific slope.

The first four items of the projected work are designed
to secure proper ventilation, open new ground, and furnish
adequate facilities for working; the ground already parti-
ally explored.

20

The latter item to constitute a new and grander system
of development, and I give a few ot the many reasons call-
ing for immediate work in this direction :

1st. The cutting of veins not encountered in the Britannic
tunnel or other workings, but known to exist on both sides
of the mountain.

2d. The opening of large bodies of ore in the Baltic,
Blue, Kevenue, and other veins now being worked, and in
the most favorable manner.

3d. The probabilities that the many veins cut by the
Britannic tunnel will be found concentrated into a few larger
veins at this greater depth, and thus be worked at less ex-
pense.

4th. The increased facilities for handling and marketing
ores.

On the Pacific slope, where it is proposed to start this
tunnel, we are much nearer railroad connections, and the
expense to get the ore to the market will be greatly re-
duced ; the water supply is more regular for steam purposes,
and there is less danger of snow-slides and consequent im-
pediment to the work. In order to secure the best results'
in this, as in every other enterprise, it is necessary that
ample funds should be provided for machinery plants and
development-work. This property being already developed
to a depth of over 500 feet, its value is a demonstrated fact.
The continuity of the ore bodies and their increasing strength
and richness is known, and there is not the slightest doubt
as to their permanence, and therefore, in the future, all plans
should be made with the idea ot prosecuting the work to
great depths. Powerful and automatic machinery should
be provided, and, while carefully guarding against the mis-
takes and reckless expenditures of the past, no money should
be spared to make the improvements permanent in their
character.

So far, in this State, proper attention has not been paid
to the use of labor-saving devices in connection with the
mining industry. In driving the tunnels and other work
on this property I would advise, so far as practicable, the
use of power-drills, automatic transportation of the ore,
and every device by which time and money can be saved,
even if the first cost ot the plant is large, in the long run
itwill pay to use automatic appliances wherever possible, and

21

to pay good prices for hand labor when machinery cannot
be substituted.

With an adequate plant and working capital this property
can, at a low estimate, be made to produce handseme divi-
dends on a capital of $500,000 invested, and is now in much
better shape to produce such dividends than are a majority
of the mining properties of the State.

From year to year its output can be increased a? new
ground is opened and better facilities are provided for the
extraction and treatment of its ores. If the lower tunnel
is at once driven to a junction with the Baltic and Revenue
veins, (which will at that depth be united,) a body of ore
will be exposed and available worth many times the price
now asked for the property. For every foot of levels driven
irom such point of junction at least one hundred tons of ore
will be ready for extraction, worth from $75 to $10u per
ton. This is not a wild estimate, but a reasonable deduc-
tion from past experience in the upper workings. By refer-
ence to the maps accompanying this report you will see at
a glance how admirably this property is located for a sys-
tematic development by cross-cut tunnels.

Revenue Mountain is a portion of The Great Divide, or
Continental Watershed, and is cut by an unusual number
of true fissure veins, running nearly parallel with the divide,
and outcropping at an elevation of over 12,000 feet above
sea level. At this point the divide is comparatively nar-
row or thin. It is, therefore, practicable to speedily cut
these veins at nearly a right angle by these cross-cut tun-
nels, and thus open up large reserves of ore, while securing
perfect ventilation and drainage and the means of extract-
ing ore at a minimum cost. The importance of such a
location is never underestimated by practical miners, and
should not be overlooked by investors. Hoisting ore and
water from great depths, as is necessary when confined to
shaft work only, is one of the largest items of mining ex-
penses, and should only be resorted to when the conforma-
tion of the ground will not permit of a system of tnnnels.

The maps and plats accompanying this report will give
you a good idea in detail of the location of the property
and the work accomplished to date. The proposed lower
tunnel noted on two of the maps is the one projected and
commenced by the old company on the Atlantic slope, and
only cuts the veins 400 feet lower or deeper than the

22

Britannic tunnel. My suggestion is in regard to a deep
tunnel from the other, (Pacific slope,) the mouth of which
would not be more than one mile distant from the track of
the Denver, South Park and Pacific Railroad, at Decatur,
to which point surveys have been completed, and where
smelting works will doubtless be erected during the coming
season. This proposed tunnel will cut the veins from 200
to 300 feet deeper than is practicable irom the other slope,
and save at least 12 miles of ore transportation. It may
also become valuable as a means ot railroad communica-
tion through the great range, it being the quickest and most
accessible route out.

ORE RESERVES.

There is now in sight in the Baltic vein, below the 120
feet level, a block of ground 248 feet long by 155 feet in
depth, and averaging at least 9 inches in thickness,
which will yield 3,803 tons of ore, worth at least $90 per
ton, or a total of $342,292, while scattered through the old
Baltic stopes, in the workings of the Celtic, Revenue, and
Leviathan vein No. 2, good ore is exposed, which would,
though not technically in sight, aggregate aa equal amount,
or a total of nearly a million dollars worth of ore, exposed in
the present workings. Cut this down even 50 per cent, for
expenses of extraction and treatment, and a handsome mar^
gin remains.

Before making this estimate, I went carefully through
all the workings below the 120 feet level, taking samples
across the high grade ore streak, (which averaged more
than 12 inches every 4 or 5 feet, regardless of the grade of
ore,) my assays gave, from three large lots taken in this
manner, respectively, 140.6, 102.5, and 30.2 ounces of silver,
or an average of 91.2 per ton.

In conclusion, I can heartily commend this property as
one of the best in the entire region devoted to mining. The
estate is large, and very valuable in all respects. The
tract of land at and near Grant, including that town site, is
finely located well watered and timbered, and yearly in^
creasing in value. The mill and tunnel sites are also de-
sirably located. The lode claims are true fissures, and
therefore destined to hold their value for many years,
Clear Creek county, in which they are located, ranks as one

23

of the largest and surest producers in the State, having
yielded since 1859 over $20,000,000 of the precious metals,
and each year increasing her output. However valuable
for the time being, deposits of ore may be, it is to fissure-
vein mining we must look for that steady and never failing
supply of gold and silver which gives wealth to the nation
and the judicious investor. I cannot insist too strongly that
if your friends interest themselves in this property they
should bring to the enterprise the same business capacity
that characterizes all other successful business ventures.
The mining industry has carried, in years past, a load of
ignorance and incapacity that would have swamped any
other industry, and had it not been for the exceptionally
large profits arising from the few enterprises that were
fairly managed, even it could not have survived. There
are to-day thousands of dollars lying in the slag dump of
the Geneva smelter that should have gone as dividends to its
owners ; and all over this State, like monuments of folly, ex-
ist to remind you and us of the sure effects of ignorance and
mismanagement. With attention to three important items,
men of capital can secure magnificent returns from mining ;
without this attention the results of investment must nearly
always prove disastrous: First, secure property that pos-
sesses intrinsic value and gives assurance of permanency ;
second, provide the enterprise with an adequate working
capital; third, employ practical mining skill in the man-
agement of your property.

In the Geneva Mining Estate you will find the first requi-
site, and my experience and observation both teach that
if you will meet the other requisites you will be greatly
benefitted and immensely repaid. In this particular case
and with this property it rests entirely with the manage-
ment to make the enterprise a glorious success.

Eespectfully yours,
(Signed) A. W. KELLOGG.

NOTE. — In making our estimates at least 25 per cent, should be ad-

make the total $48,092.85.

We find, by corresponding with men who held leases on

DENVER, COL., May 15, 1883.
GEN. B. B. SIMMES,

Denver, Col.:

MY DEAR SIK : I learn with pleasure that you have se-
cured the Geneva property, and in response to your inquiries
can say briefly, that you have obtained one of the best prop-
erties in the State. I prepared a report on this property
in January, 1882, for a Mr. Godfrey, of New York city,
which gives full details in regard to the extent of the prop-
erty and its development. You doubtless have a copy of
this report, and I am at this time confident that no state-
ments were therein made which will not stand the closest
examination and be confirmed by any reliable expert.
Since writing that report I have visited many of the lead-
ing mines of the State and find none that excel the Geneva
combination, both in present and prospective value, and I
therefore congratulate you on your purchase.

It is now understood that the Chicago, Burlington, &
Quincy E. E. will extend its line across the head of Geneva
Gulch this season, its track passing within 200 yards of the
mine, and thus putting the property in direct connection
with Denver and other smelting centres. The Denver, South
Park. & Pacific E. E. is also pushing its line up the Snake
river to Decatur, and will be running regular trains from
that point this year. The smelting works at Decatur, of
which mention is made in my report, are under construction
and will buy ore this season.

All over the State the mining prospects are flattering and
the output of ore for the first quarter of this year gives as-
surance that the yield of precious metals for 1883 will be
many millions in excess oi any previous year.

I was shown yesterday a large sample of ore taken from
the Terrible mine at Georgetown, (same county and Mineral
Belt as that in which Geneva is situate,) which runs from
900 to 1,200 ounces in silver. This ore was from the depth
of 1,300 feet, the lower workings of the mine, and at this
point the vein is stronger and richer than at any other
depth in the mine. This should give you renewed confi-
dence in deep mining, and in tne permanence and value of
the Geneva property.

29

You enter upon the mining business at a very favorable
time, recent improvements in mining and mill machinery
make it possible to mine and mill ores at a profit, which a
few years ago could not be handled, while the extension of
our various railroad systems to remote camps is bringing a
greater variety and quantity of ore to market and rendering
it possible to establish large smelting works where our ores
can be treated at a minimum cost.

There are many thousand dollars now lying idle in the
ore and slag dumps of the Geneva property that can be
made available this season, it not having been practicable
hitherto to move this slag and ore on account of heavy
transportation and smelting charges. Under wise manage-
ment the Geneva property should pay handsome monthly
dividends for years to come on a capitalization of $500,000,
and if I owned the property with capital enough to provide
a good plant of automatic machinery, I would not sell it at
that figure.

With best wishes for your success, and the assurance that
I shall be glad, at any time, to furnish you with any infor-
mation I may possess in regard to the property or the best
mode of working it,

I remain,

Yours, very truly,

A. W. KELLOGG,

COPY OF REPORT OF PROF. BOARD,

OP THE

SCHOOL OF MINES, GOLDEN, COL.,

UPON THE REVENUE GROUP.

(NOW KNOWN AS THE GENEVA GROUP.)

This property has been worked from the surface for some
years past ; more lately, however, these surface workings
have been partially abandoned, owing to the expense con-
sequent upon hoisting from the lower levels after they had
been carried down to the depth of 200 feet. The mine hav-
ing been proved beyond question a rich and paying one,
the decision was come to to open it by a tunnel which
would (besides intersecting many other prominent veins be-
longing to the company) cut the Revenue Mine at the depth
of 400 leet. This tunnel, known as the Britannic Tunnel,
has been driven in during the last three years, and has been
carried a distance of 1,025 feet, cutting on its way no less
then fourteen veins, three of which only have been worked
on — the " Celtic" " Baltic" and '' Revenue" It has been
considered of primary importance to push on the tunnel,
the other eleven veins were only sufficiently worked on to
determine their general bearing (vide Plan, No. 1.)

Britannic Tunnel is driven from the head of Geneva Gulch,
on the Atlantic Watershed, about 8° north of west, or al-
most at right angles to the general lay of the dividing
ridge, which is almost due north and south, and gaining the
crest of which, the Pacific Watershed is reached. The
tunnel, if pushed about 300 feet further, would, in fact, be-
come a connecting link between the waters of the Platte on
the east, and of the Snake on the western side of the range.

The geological formation exposed by the Britannic Tun-
nel is similar to that of the Georgetown district on the

31

north, and the St. John's Mines on the south; the whole of
the great mineral belt which intersects Colorado being, in
fact, the same; that is, the belt in which true fissure veins
occur. Gneiss, interstratified by veins of porphyry, granite,
and other metamorphic rocks, is the country rock of the
district, which in this case seems to be perfectly riddled with
mineral-bearing veins, which can readily be traced on the
surface from a point about half a mile northeast of the Reve-
nue workings to 1 J miles southwest, where the Montezuma
district is reached, through which the veins pass to the St.
John's district, also to the head of Deer Creek, the Snake
and Hall Valley.

THE CELTIC MIXE (No. 7 on the map) was the first cut
by the tunnel on which any important work was done, it
being deemed necessary to take advantage of its surface
shait and make connection with the tunnel for ventilation,
as well as to develop; the vein being a large and promising
one, and cut at 454 feet in, this point being 240 feet from
the surface. This shaft has developed a vein from six inches
to (in places) 2 J feet wide, the ore consisting of yellow and
grey copper, galena, zinc-blende and iron pyrites. It will
average about 50 ounces of silver per ton, and when worked
can give a large yield.

THE BALTIC MINE (No. 10 on the map) has been actively
working during the past season. A roomy engine-house
has been blasted out, and a shaft sunk 120 feet, and a rise
put up 123 feet. From the tunnel levels have been driven
east 189 feet, and west 160 feet; at a point 60 feet below
the tunnell levels a drift has been driven east 126 feet, and
west 71 feet. The best body of ore is down below these
levels, being 12 inches thick and very rich ; but a good aver-
age body of six inches is visible through almost the entire
workings; and when the 120-foot levels are driven in, so as
to open the best stopes, a production oi about 10 tons is ex-
pected, which will average 100 to 120 ounces. The last lot
of first class, which was sold to Professor Hill (seven tons),
gave an average of 265 ounces. To-day the Baltic Mine
could not produce one-half of the estimated yield; but it
must be borne in mind that whilst the rich ore in the shaft
has been exposed, the drifts are not yet sufficiently advanced
to enable stopes to be started, or the mine in any way to do
itself justice. It is intended to sink the main shaft a fur-

32

ther distance of 340 feet, and connect it with a second tun-
nel from the Geneva basin, which would work, drain and
ventilate the whole property, and give the mine a "back"
of about 800 feet, and the Revenue one of 900.

The ore from the mine is particularly clean, and free from
spar and gangue, and consists of iron pyrites, generally en-
closing a broad streak of grey copper quartz, sprinkled lib-
erally with brittle silver and occasional small streaks of
galena or blende. On the surface a shaft has been sunk for
35 feet, and bismuth, silver, galena aud grey copper met
with in separate streaks. The crevice is large and well de-
fined, and unmistakably a true fissure.

THE REVENUE MINE (No. 12 on the Plan) is the next on
which important work has been done, and is the mother
vein of the district. When first struck, it was a narrow and
unimportant looking streak, but after a raise nad been put
up some 30 feet, a large body of ore was struck. At the
point of intersection with the tunnel the vein was 888 feet
in, and 400 feet from the surface. The "rise" has now been
put up 70 feet and is intended to connect with the 180-foot
shaft of the upper workings. This will probably be done
in the early spring of 1884, which will at once give a ready
and cheap access to the large bodies of ore left standing in
the " Upper Mine," and largely increase the daily yield.
A drift is now being driven west from the Revenue rise,
and a very good body of ore struck, a sample from which,
lately assayed, is said to have given 1,260 ounces per ton.
The average of the mine has been about 75 ounces, and
yields about a ton to the fathom. The ore is chiefly grey
copper and galena, mixed with heavy spar and some little
blende, with iron and copper pyrites. The vein matter ex-
tends to 12 to 14 feet, and the lode is almost perpendicular,
all the others pitching in a greater or less angle in towards it.
It is my opinion that at greater depths those lodes will come
together and form one large body, in which case the ex-
penses of running would be decreased and the yield increased.
The vein which runs along the ridge of the mountain has
been opened from the surface by three shafts, 180, 120, 70
feet deep, which have been connected with levels driven on
the lode, and exposing a strong and valuable vein for a dis-
tance of about 300 feet. Part of this ground is now leased
out, the men making good pay, though they have to pack

33

the ore to Georgetown (23 miles by trail), pay all expenses
and a royalty to the company of 25 per cent. Large board-
ing houses and ore-sheds have been constructed at the mouth
of the tunnel, and others, together with the company's of-
fices on the plateau below, from which the lower tunnel is
to start. The furnace- house, saw-mills, general offices and
stores have recently been constructed in the valley below,
where ample supplies of timber and iron ore beds have been
secured.

The other veins belonging to the company on the Atlantic
slope, which have already been|(or will be) cut by the tunnel,
are the "Kepublic," "Gaelic," "Adriatic," "Belgic," "Oce-
anic," "Dramatic," "Comic," and part of the "Perry Hunt,"
and u Congress."

THE LEVIATHAN TUNNEL, belonging to Detroit and Bal-
timore parties, is situated about 900 feet southwest of the
Brittanic Tunnel, and has been driven in 800 feet, inter-
secting several promising lodes. The latest cut is one show-
ing 15 inches of ore, with 100 ounces per ton, chiefly iron
pyrites. A large quantity of ore may be mined here next
season. About a mile west of the Brittanic Tunnel, and in
the horse-shoe adjacent to Montezuma district, are a num
ber of important veins, the most prominent of which is the
'' Colorado," owned chiefly in London. A large sum has
been expended in the development of this property. A
shaft has been sunk about 70 feet, and intersected by a
cross-cut tunnel about 120 feet, and drifts run out northeast
and southwest on the vein for some 200 feet — a short upper
drift, some 40 feet. Here a large body of ore has been ex-
posed, chiefly galena, carrying from 55 to 60 ounces per
ton ; but, owing to the difficulty and expense hitherto ex-
perienced in packing the ore to market, the mine has been
remaining idle for the past year.

A tunnel has been started below, and driven in about
150 feet, which will, when completed, give a back of at
least 350 feet, and make the ore to be mined much more
cheaply. Like the whole of the Kevenue property, this
mine is secured by a United States patent. Other more
prominent mines in the immediate vicinity may be enu-
merated as follows : The Treasure Vault, Silver Bell, Elgin.
St. Charles, Chicago, Silver Glen, Naval, Gilman (extension
of the Colorado), Eagle Bird, Bob Tail, Queen, Modoc,

34

Santa Fe, Anglo-Saxon, Sherman, Mary Anne, A. V. Sill,
Comstock, Victoria, Minnie, May Flower, America, York
Town, Lexington, Centennial, Casino, Elendale, Tainburg,
Corkingdale, Joe Lee, Perry Hunt, Congress, Star, Green,
Blue, etc., etc. Of these, besides the Colorado, the Star,
Silver Bell, Gilman, Green, Treasure Yault, and one or two
others, have had a considerable amount of work done, and
show, as do indeed most of the others, good bodies of ore ;
but the high rates of freight hitherto prevalent have, in
most cases, checked both development and production, so
that the whole district may be said to be in its infancy.
The completion of the wagon road, built by the Revenue
Company to Grant, will stimulate work not a little ; but
with the facilities afforded by railroad communication, it is
believed that the whole district must rapidly assume the
position nature has given it every chance of getting —
namely, one of the surest and largest producing districts of
Colorado. In conclusion, I would again briefly refer to
the Revenue Company's property. It is, beyond all ques-
tion, a very valuable one, the true fissure character and
richness of the veins being beyond all question. The rich
ore exposed in the Baltic shaft will be available at a mini-
mum cost when the drifts below (now in progress) are push-
ed further in, and the stopes opened. This work is now
rapidly progressing, and when these stopes are opened, and
when, in the Revenue Mine, the connection between the
70-foot rise and the 180-foot shaft has been made, the gene-
ral production — which to-day, by careful calculation, is es-
timated to be from 5 to 7 tons per diem — would be con-
siderably more than doubled ; whilst, when the lower tun-
nel intersects the veins on the 900-foot level, and the Ger-
manic Tunnel, cutting the surface workings near the north-
east boundary, and connected with them by the extension
of the present levels, enables the whole of the upper work-
ings to be brought into play, discharging their ore by the
main shaft to the 900-foot level, the product of these mines
daily may be confidently estimated as second to but very
few indeed in the State. From my personal examinations
of the Geneva and St. John's Mines, together with the re-
ports I have heard of the adjacent districts of Montezuraa,
Deer Creek, and the head waters of the Snake River, and
with the knowledge gained by the purchase and smelting of
many tons of ore from these and surrounding districts, I

35

believe a daily production of 100 tons is the very least that
can be estimated ; and that these veins will be permanent
producers, in contradistinction to those of deposit forma-
tions, is also beyond doubt. The broad rule, too, of rich-
ness increasing with depth (which is not always a safe one
to base estimates on) seems, in the case of the Revenue
Group, to be substantially borne out ; ior by far the rich-
est ore yet struck is in the deepest workings, the body lately
struck 60 feet below the tunnel level (extending to 120 feet
to the bottom of the shaft) assaying, the superintendent in-
forms me, as high as from 2,000 to 3,000 ounces per ton.

Explanatory of the above report, I herewith forward the
longitudinal Plan of Britannic Tunnel, showing the va-
rious veins hitherto struck ; Section of the Revenue Moun-
tain, showing the course of said lodes, also the points of
intersection by Revenue Tunnel, and the line of proposed
lower tunnel ; Section of Baltic Mine, showing ground al-
ready opened and that stoped out up to date.
