Officials Of Southwestern Nevada
Mines Company Tell of Good
Work Accomplished Dur
the Past Year.

Malcolm Mcdonald, the general man
ager OF the company, have just been
made public.
President Knox states the com
pany is in an excellent condition
financially and that the houldings
which consist of twelve full claims

about sixty miles from Tonopah.
nave greatly increased in value dur
ing the past year.
General Manager McDonald's re-
port deals with the workings of the
mine and W. quote from it as fol-
lows:
10 the President and Board of Di-
rectors of the Southwestern Ne
yada Mines Company.
Gentlemen IL herewith submit
my annual report, giving in detail,
the work that has been done at your
properties during the year and the
future possibilities of the mine The
properties are situated about four
miles from the town of Reyeille. and
about sixty mills east of Tonopah. in
the Reveille range of mountains.
which have a general n%ortherly and
%southerly strike. The different for
nations consist Of rhyollte. lime and
quartzite. The lime and quartzite
being s~edimentary, aere undoubtedly
nat deposits, and were later tilted by
the erupted rock rhyolite. The ore
occurs between the quartzite and
lime. the former being the footwall
OF the deposits. This was, in my
opinion, deposited from hot ascend
ing solutions. between the lime and
quartzite, depositing the metals, sill
yer and lead, as e%arbonates and sui
phides. The ledge ore body was dis
covered through an incline shaft on
the lime quartzite, and on account of
this ore settling away from The
hanging wall for a distance of from
one 70 ten feet, it gave an excellent
opportunity TO prospect the ore be-
Tor commencing development work.
After thoroughly examining the ore
body. a tunnel was started and run
for a distance Of two hundred feet 10
The same deposit of ore that was dis
covered through the old incline shaft.
This tunnel saved the expense of
hosting, and cut the ore dody about
!.
100 feet lower than the old workings.
lt also proved hat the ore is continu-
Gus from the point where he in
clint came into the ore, TO the tun-
net level Further development
WORK was continual through the tnn-
mel level by running a DRIFT along the
contact on the east side of the de-
post, Off a distance of 1926 feet. and
on he west size for a distance OF 40
feet. A prospecting winze was sunk

which proved to be l20 feet. This
proved the continuation of the ore
deposit to this depth. Another
Wine was then started from this
level on the hanging wall, and sunk

run 100 feet, proving the continuity
Of the ore body This work was m
done by hand, aud therefore expea-
slye Only enough drifting was
done at this level to prove that the
ere was continuous for a distance Of
1870 feet below the main tunnel level.
when all Of this prospecting work on
The lower levels was discontinued f,
until permanent mining operations !
could be commenced by the sinking
Of a double compartment shaft
through the lime Gaping to the ore
bodies. {.
During the year there has been :
total OF 912 feet Of development
work,
This Is exclusive of stopping. In the
prosecution of this work we have
mined about 1000 tons of nrst class [
and 1000 tons of second class ore. '
The first class has a value of about
St5 per ton, a portion Of which has
shipped, the balance remaining
On the dump. The second class ore |
a value of $40 per ton, and is
a smelling grade. The develop
hents which have been considered so
do not include the old workings

II Is therefore strongly advised :
NAT a modern hosting plant be in
stalled to sink a vertical shaft to de-

greater depth, and at less expense
