NEVADA AUSTIN
ERECTS PLANT
PROPERTY IN LANDER COUNTY
BEING EQUIPPED To TREAT
OUTPUT

Nv PAN
the Nevada Austin Mines company's
property at Newpass, % miles from
Austin in Lander county, has been
started, was the announcement
made by Frank Margrave, president
and general manager of the COM
pany.
The Nevada Austin Mines COM
pany owns eight claims in the dis
trict which we're taken under OPP
ton about a year ago by Margrave
and associates from Cunningham
and Baird of Salt Lake City. Over
10000 feet of work has been done
in the four tunnels on the property
and 600 feet of this WORK was on
two of the five parallel veins that
traverse the property.
The ore from the tunnels, oil
which there is several thousand tons
o piled on the dumps, runs about
20 per cent in free go'T in its val
ues and, according to tests
made for Margrave, a high eytrac-
ton can be secured with a cyanide
plant. After having the property
examined by experts and the ore
blocked out, Margrave decided to
erect the mill and has employed
Douglas Muir, metallurgical engi-
neer. to draw the plans aud super
intend the construction OF the p'an:.
I'VE have made examinations or
plants in all parts of the country.
said M~argrave, "'in order 10 deter
mine Just what kind of a plant we
will put in. Our Investigations
were exhaustive, covering the great
err part of a year and the plans are
now complete The ore VIII De
crushed in a Blake jaw crusher and
then sent through steel pail tube
mills.
According to mill tests the full
extraction from the ore can be Sc
cured when it is ground to lO-mesh,
but in order to avoid mecl&nlcal
difficulties caused by the settlinS
sand in the classifiers and tnicNen-
ers. we expect to crush to ABOUT So
mesh in the steel ball mills.
The mill will be e%quippet with
Dorr thickeners and ~agitato"s, Oh
yer filters and Merrill zinc dust pre-
cipitating press. 1t will be operated
by power furnished by a 100 n. p.
DIESEL engine. One of the interest
ing features of the plant aud one
that will save a big sum in operat-
ing expenses will be the lns,al'atlon
of an apparatus to use the exhaust
gases from the DIESEL engine in
heating the solutions in the tanks
during the winter.
1--WE have just completed "A five
mile pipe line from Gilbert Creek
which will supply plenty OF water
for the plant. This creek VIII sup
plv 200 gallons a minute, thus as
surfing us that this feature OF the
operations, which has caused con-
siderable trouble and eXpeuse IN
other mills. will be we'll taken care
Of"
After taking the option on the
property Margrave made a caretul
study of the conditions and the lay
of the veins and then started work
in the lowest of four tunnels thai
had already been driven 12oo feet
bv the former owners. The T
tunnels above had been driven on
the ore for 400, 500 and Zoo feet'
respectively. In the lower tunnel
the former operators failed to strike
the vein where they expected and
rave up the work.
For several hundred feet the w
mel had been driven on a Straleht
line. and then a small quartz string
err. apparently a fault, was picked
I'D and followed on a bend untii the
~12OO-foot mark had been reached.
The stringer did not lead to tie
vein and the work was finally
abandoned. They had drifted to
the east Of the tunnel in several
places, but failed to strike the Vein.
Certain that the vein which had
been opened up so Well in the upper
tunnels continued dowl, MargraVe
secured Paul Hursh, old-time miner,
to take charge Of t;,e ~ope'at.ons
Hursh drove a dris, to the wet at
the face of the tunnei ard picked
up the ore in IL feet. He then went
back several hundred feet tro!l The
ACE and opened the ore in a five
foot raise.
The former owners had driven
the tunnel under and TO the cas- OF
the vein for several hundred feet,
apparently being fooled by the dip
of the vein, which changed slightly
from that maintained in TIE uple'
tunnels. Phil Hursh." sail Mar
