BUCKHoRM MINE DESCRIBED
Ore Said to Be Easily and Cheap
ly Mined and Treated by
New Process

= ID OF the Hill OF the
Buckhorn Mines Company and its
successful test are announced by
Fred j. Siebert, who is associated
with George Wingfeld and others
in this company. Mr.. Siebert upon
his return from the property, which
is located 80 miles south of Beowawe,
said to the Reno Gazette:
"The Buckhorn mine was dis
covered in the Winter of 10000 by
Joe Lynn. His partners were w. S.
McCrea, William Ebert, James
Dwyer and John Swan. | made a
preliminary examination of the prop
erty on August 8, 1909, and return
ed on August 10 and made a thor
ough examination.
Low Cost Of Operation
"Mr. Wingfeld and associates pur-
chased the property on September 5,
1909. for $4,000 and subsequently
Mr.. Wingfield bought extensions,
bringing the total price for the hold
ing of Ia claims and several fractions
up to $4,000. The deal was COM
pleted on April 1, 1910, without wait
ing for the time of the option to be
concluded. Since then 10000 feet
of development work has been done,
exposing an enormous tonnage of
low-grade ore.
The amount of tonnage that will
be worked in the mill depends entire
ly upon the working costs which we
may be able to secure in actual OPP
erations. With this end in view the
best mining and milling machinery
has been installed together with an
effective power plant.
"The mill is up-to-date. 1t was de-
signed to reduce the pres at the low
est possible cost and with the great
est amount of extraction. 1t is ex-
pected to treat between $50 and 400
tons daily. The power plant is sit
uated at Beowawe. 1t contains two
powerful engines directly connected
with general Electric generators
having a capacity of from ITO to $50
| horsepower. The transmission line
is approximately 80 miles in length.
The total cost of mining and milling
the ore is expected to be less than
$2.75 per ton.
In Class of Its Own
"The mine is different from any
other in the world. The central
core of the ore body is an intruded
porphyry (augite andesite) intruded
through many different alternating
sheets of bazalt and volcanic scoria.
This central core has been the solu-
ton channel and the values have
spread out to large widths in the
beds of basalt and ~scoria, which have
been favorable to ore deposition.
These beds of scoria have been
most favorable on account of their
porous nature. but some of the soft
er basalt flows have also formed
large deposits. So far as the work
has progressed it shows nine differ
ent basalt flows and a similar number
of scoria beds.
"The prime movers are at Beo-
wave and everything at the mine is
done electrically. The main haulage
from the mine is $500 feet long, 1850
feet of which is underground and
transportation is by electric loco
motives.
From the central core of the aug
lite andesite the values fade each sav
and tonnage depends therefore upon
the cost of operation, but the COM
mercial values are in places at least
l5O feet in width. The ore zone, so
far as proven, is about 1900 feet in
length.
"The first hundred feet of depth
on the deposit includes practically all
of the oxidized ore. which will be
mined and milled first. The deposit
to that point is almost vertical. 1t
will be mined by the glory hole sys-
tenn. Below this depth the deposit
turns off rather fiat and will be mined
by the top slice system, which is in
effect the most up-to-date system of
caving.
