ing. A vertical shaft sinks to d
depth of 652 feet by the side OF the
vein. This reaches a point consid-
erably below the lowest No 3. level.
The plan is to pump water from the
bottom of the shaft to the 300-foot
level and pass il out through the
No. 3 ~crosscut. Drifts on the ore
have been run from each station
both ways from the shaft. The
longest drift is 900 feet on the
sixth level, other drifts being 400
feet and over.
The shaft on the Buffalo claim is
400 feet southwest OF the Monarch
shaft, reaching 900 feet in depth
This is an old shaft and the in
tcntion is 20 drive a crosscut from
the surface to tap this shaft at a
point 800 feet below the collar. This
crosscut will be 200 feet lower than
the Monarch's lowest tunnel level.
The Last Chance has a separate
vein. The workings will be con-
ncctcd so as to deliver ore from all
parts of the group to the top OF the
main shaft where the r bins con-
noct with the upper terminal OF the
aerial tramway. Besides the bodies
of ore exposed in the mine there is
said to be $50, 900 ton of ore Of
good milling grade on the dumps,
much of which was the result Of old
workings.
The tramway line, connecting the
mine with the mill, Is II miles in
length. II is the Bicichcrt system
made by the Trenton Iron Works.
This line is a fine piece of work
and is nov in working order. II
cost $34, 600.
The mill building is up and en-
closed and the machinery is being
installed as rapidly as it can be
hauled in, but the long distance
from the railroad occasions much
delay.
The plant of the mill provides for
crushing, amalgamation, rcgrind-
ing, concentration and cyanidation,
accompanies by thorough classified
ton and sizing. A Gates crusher,
two sets OF Sherman rolls and five
Huntington mills will do the crush
ing and regrindirg. The concer-
trating will be performed by 10
Sherman tables. The shines re-
s%ulting from regrindings will pass
to a series OF hydraulic STEERS, the
heavier product from the latter pass
ing to tables and the overflow to
cyanide tanks. The principal saw
ing is expected to be as the result
of concentration, though consider
able value will doubtless be caught
on the amalgam plates and that in
the lighter shines by cyanide. F.
w. Sherman of Salt Lake planned
the mill and he has the contract to
supply the machinery. The mill
will operate by wafer power, two
De Reymer water wheels having
been installed for this purpose. A
100-horsc power electric motor has
also been installed in the mill for
power purposes in Ease of accident
