FERGUS COUNTY MINES.

1t is learned upon the authority of
Grant Robinson manager of the Kendall
group of mines. situated in the North
Moccasin mountains, that the work upon
the tunnel commenced on the Leaking
lode is being prosecuted as rapidly as the
nature of the ground and other condi-
tons will permit. depth has already
been attained of 85 feet, and no change l.,
yet apparent in the quality of the ore
discovered at the point from which oper-
atoms were begun. Barring accidents
and other causes, a week longer will see
the tunnel driven to a depth of 1875 feet,
when prosecuting will begin; but this
will not interfere with the prosecution of
the tunnel along the main body of ore.
The plan now is to continue work on the
tunnel for a further distance of 315 feet.
The amount of ore now being extracted
fl ON the mine will average in the neigh
hOrhoOd of 40 tons per day. and is taken
to the mill for treatment as fast as it is
taken out
The new cyanide mill of A. S. Wright
d Co., situated at the head of Cave
gulch, was started Monday morning.
:. his mil is a large one, having ca
pacity of of 220 tons of ore a day, and en-
bodies number of improvements not

operation in Fergus county. It's manage
ment is in the hands of such careful men
as A. L. Losnger and j. II. Mccormick
both OF whose names is a guarantee of
the successful outcome of the enterprise
The mill was designed primarily for the
treatment of the ores extracted from the
Whisky Gulch group of mines. and hence
is known as the Whisky Gulch MILL al
though it occupies a site somewhat re-
moved from the properties whence it de-
riveS it's name. The mill has been con-
structed on what is known in mining
parlance as the terrace plan, having
four floors, one above the other, the first
or upper floor being connected by chute
with an ore bin capable of holding three
tons of ore at one time. A Gates crush
er, with a crushing capacity of so tons
per hour, receives the ore from this
chute after it is passed over a screen.
When the ore has been sufficiently re-
duced by this process, it is conveyed by
a belt cup conveyor, by means of which it
is raised and dumped into revoly-
ing ne-fourth-inch mesh revolving
screen. The fine ores are then carried
through a trough to the teaching tanks
on a belt conveyor, the coarser pieces in
the meanwhile passing through another
trough to another Gates rollers, where
they are subjected to another crushing
process and are then carried by sec
ond cup conveyor into another revolving
screen. Here the fines, as in the first
instance. pass to belt conveyors and
thence to the tanks. the residue being
taken back to the rolls for further treat
ment.
The ore in the tanks is distributed in
the bottoms of the tanks by a species Of
horizontal revolving bar, which is SO
constructed as to level the ore. and takes
the place of a man. The four tanks are
arranged SO as to take up very little
room. The tanks each have depth of S
feet and 8 inches, and are 25 feet inches
in diameter and are capable Of holding
! 20 tons. They are equipped with false
bottom meshes TOR filtering purposes, the
| solution being introduced through a per.
forated crossed pipe l Il inches in dame
ter. The second application is made in
| the usual method by hose from the top.
The mill is supplied with three large So
| luton tanks. The original solution tank
| has been placed on the second upper ter
| race at some distance above the Stun
| tanks, to which it passes in such way
to thoroughly saturate the ore below.
! When the solution has performed it's

pipes into what is known as the settling
| tanks, and then passes into four round
| bottom zinc boxes. From the stump tank
/ into which it goes from the zinc boxes,
! the solution is pumped into the original
solution tank, and then back to the start
! ing point.
The company has spared no pains to
make their mill complete in every re-
| Spect and have constructed everything
rs edful in the way of offices, stores.
! boarding houses, etc, for this purpose.
It is now engaged in carrying on opera :

! ent will not run the mill except to re-
duce such ore as may be taken out in
the course of the development work done
Upon their claims. Just now the greater
Fart of this work is being done on the
Cloud lode, upon which claim four tun-
nels are being driven.
