INSPECTION OF
SEVEN TROUGHS
Local Mining Man Returns
From Camp an EnthuSi-
asst on Its Merits.
EXAMINES LEADING MINE
AND SUBMITS CALCULATIONS ON
ITS VALUE.

On his own account and in the inter
ests of a number of operators who
have holdings in the Seven Troughs
en- Troughs district, r. ]. Evans has
been making an inspection of the mine.
He returned yesterday morning abso-
lutely convinced that the property was
a big one, and that the camp, the en-
tire camp, was one of exceptional mer-
it. He states that Salt Lakers are go
ing to make the mistake of their lives
if they don't capture the mines and
business Of the Seven Troughs camp.
He cites that this city let Tonopah and
Goldfield get away from it and, he de-
clares. that neither of them. big as
they have been and are, will begin to
rank with Seven Troughs when once
the camp has squared away for action.
Yesterday afternoon Mr.. Evans pre-
pared statement which he is going to
submit to those who were largely re
sponsible for his trip to the mine. FROM
it the following extracts are made:
Il found the surface improvements
"a consist of an engine house, enclos-
iHs an engine capable of handling the
whole of the present work to the depth
of 525 feet; a blacksmith shop. tool
room, change room and a good ore
house. A splendid two-compartment
shaft, sunk to the depth of SIS feet,
well timbered and lighted at each sta
ton by electricity, furnished by the.
cOmpdnyRs own works. On the surface
at a point on the vein some fifty feet
from the present working shaft, and i'm
gully, marks the only place where the
ore is exposed. and there only for some
few inches, covering the width of the
trail made by the sheep and furnish
ing the inducement for further pros
pecting by the discoveries.
Underground Development.
Going down the shaft to the 1eO-
foot level, 1 found the vein was en-
cOuntered a few feet from the shaft by
a cross-cut and that drifts north and
south for a distance of 100 feet or more
were all in ore and exposing a streak
of high-grade on the foot wall seventy
five feet or more in length. The vein
is white quartz, and some ten or twelve
feet wide, with the white quartz or pay
shoot twelve to sixteen inches. The
values contained IN this shoot run from
SO to 800 per pound. The next three
feet of ore laying on sthe line to the
high-grade shoot will carry values from
S25 to $50 per ton, and the balance s.
to SIS per ton.
ION the 230-foot level found a sim
liar condition to that on the 160-foot
level, but a greater strength to the
vein. The 'Jewelry shop" as the pay
shoot is commonly designated was
fully two feet wide where opened. The
ore conditions are about the same as on
the. 160-foot leSel as to the amount of
work done and exploration of the pay
shoot, and in addition thereto, the COM
pany has extended the drift on the
north side some 200 feet on the vein i'm
a good grade of ore, and carrying
values of from SO to $500 per ton.
ION the 300 and 4O0-foot levels. while
the work has not been so far advanced
as on the 230-foot level. the conditions
are identical with those on the 5G0-foot
level as far as work has advanced and
the showing is equally encouraging.
The shaft being perpendicular, and the
vein having a dip of some 70 degrees.
the amount of work necessary to reach
the vein increases as depth is gained.
Values in Sight.
81 would not attempt to give any
kind of accurate estimate of ore in
sight in this property, and l defy any

mine and do sampling without a mill
test that would be at all reliable. [
might, however, give you some idea by
a few calculations. Suppose we figure
the vein to the 400-foOt level continu-
Gus. That is four-fifths of it's present
depth. Then figure fifty feet in length
on the vein. This one-half it's pres
ent development; and then say three
feet wide, development showing it to
be six to twelve feet. We will say the
ore averages $500 per ton, while in real
ity the least ever found in the quartz
vein, after eliminating all rock that
shows free gold values in sorting, has
never run under $500 per ton, and from
that to more than $4,000 per ton Thus
we have 400 feet of depth, fifty feet of
length by three feet of width, or a total
of $4,000 cubic feet. Allowing twelve
cubic feet per ton of ore, which is high,
we have 5000 tons of ore that is worth
$500 per ton, or s1,5O0,000. These calcu-
lations are made from one fraction of
the ore body, on the north end. On the
south the vein has been opened for a
distance of 200 feet in drifting, and ap-
pears even richer than on the north
side, and samples taken every ten feet
shows the ore body to carry values
ranging from 81 to $500 per ton; the
width of this vein has not been fully
developed.
81 find the company has arranged
with parties in Lovelock, who have a
little furnace capable of reducing from
100 to 200 pounds of this fabulously
rich ore per day. Upon my arrival
there a fifty-six-pound run as the in
itial trial WIS made. The returns from
the fifty-six pounds of ore in gold and
silver was a brick weighing 1853 ounces,
and carrying better than 81 500 in gold,
in addition to its silver Values
