HISTORY OF THE
BUCKH0RN NINE
MINING ENGINEER TELLS OF
WORK ACCOMPLISHED
THERE

Fred J.. Siebert, consulting engi-
neer of the Buckhorn Mines company,
in speaking of the property of that
company in a newspaper interview in
Reno recently, said:
The Buckhorn mine was discov-
cred in the winter of 10000 by Joe
Lynn. His partners we're w. s. Nc
Crea, William Ebert, James Dwyer
and John Swan.
"Mr. Wingfield and associates pur-
chased the property on September s.,
1909, for $4,000 and subsequently
Mr.. Wingfield bought extensions
bringing the total price for the hold
fractions up to $4,000. The deal
was completed on April 1, 1910, with
out waiting for the time of the OPP
ton to be concluded. Since then
10000 feet of development work
was done, exposing an enormous ton
mage of low grade ore.
The amount of tonnage that will
be worked in the mill depends en-
tirely upon the working costs which
we may be able to secure in actual
operations. With this end in view
the best mining and milling machin-
cry has been installed together with
an effective power plant.
THE mill is up to date. 1t was
designed to reduce the ores at the
lowest possible cost and with the
greatest amount of extraction. 1t
is expected to treat between $50 and
400 tons daily. The power plant
is situated at Beowawe. 1t contains
two powerful engines directly con-
nected with General Electric gener-
ators having a capacity of from 10
to $50 horsepower. The transmits
sion 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.
THE mine is different from any
other in the world. The central core
of the orebody is an intruded por-
phyry augite andesite, intruded
through many different alternating
sheets of basalt and volcanic scoria.
This central core has been the sOlu-
ton channel and the values have
spread out to large widths.
The prime movers are at Beo-
wave and everything at the mine is
lone electrically. The main haul
age from the mine is $500 feet long,
1850 feet of which is underground
and transportation is by electric To-
comOtives.
From the central core of the
augite andesite the values fade each
way and tonnage depends therefore
upon the cost of production, but the
commercial values are in places at
least $50 feet in width. The ore
zone, so far as proven, is about 1900
feet in length.
THE first hundred feet in depth
on the deposit includes practically
all of the Oxidized ore, which will
be mined and milled first. The de-
post to that point is almost vertical.
1t will be mined by the glory-hole
system. Below this depth the de-
pOSlt turns OH rdCner nat ana Will De
mined by the top slice system, which
is in effect the most up to date system
of caving.
The mill is a straight cyanide
plant as the ore requires no amalga-
nation of concentration. The ore
contains very little quartz. and is
very easily mined and crushed. 1t
is so soft that air drills will not
be used, the only compressor being
in the mill for the purpose of agitat
ing the pulp.
practically all the drilling under
ground is done by augers. In the
glory-hole work churn drills will be
operated. A moderate amount of
powder will bring down many hun
dreds of tOns of ore, which will fall
into chutes directly connected with
the haulage tunnel and removed di-
rectly to the top of the mill.
THE company has erected a splen-
did hotel for the accommodation of
it's men. The sleeping rooms are at
considerable distance from the din
ing hall, so hat the men who are off
shift will not be disturbed in theiI
slumbers. The hotel is equipped
with shower baths and a clubroOm.
