home and the outrageous charge of the
railway corporations and the smelter
trust will be avoided and employment
given to several hundred men in the
various reduction plants. Already six
mills have been completed or are under
construction and will he ready Tor bust
ness within thirty days. Other plants
will be put up and before another wear
rolls around it is safe to predict that 80
per cent of the tonnage of the camp will
he be treated at home. The six mills
mentioned below represent a capital in
vested Of S225,000 and their combined
capacity will be 1876 tons daily. The
tonnage is not great, but the value of
the ore is however. 1t is greater than
that OF the famous Homestake or the
Treadwell-the two biggest stamp mill
gold mines on the continent. The ore
now being milled runs all the way from
Sl5 to over 81 900 a ton.
The new reduction plant at the Com
bination mine has now been in opera
ton over a week and Superintendent
Collins is enthusiastic over the way
everything has been running. 1t is n
OF the most complete mills OF it's kind in
the world and everything about it is new
and up-to-date. Ten ! $50 pound stamps

and day, and although no cleanup has
yet been made those in charge are con-
WINGED from experimental assays on the
concentrates and tailings that the plant
is making a saving ever in excess of the
percentage guaranteed by DR.. f. l..
Bosqul, who erected the mill. Anal
gamation, concentration and cyaniding
of the concentrates and shines is what is
being done and very little of the values
are found in the tailings, but to be GER
tain that the greatest saving possible
the tailings are run into a big tank and
at some future time when the little gold
contained in them is thoroughly oXi-
died, and If it is found hat they can be
handled at a profit all will again be III
4, through c~yaniding tanks. The water
supply, which is piped from Alkall
springs ten miles northwest of the mine,
) abundant. The pipe line which was
quilt at a cost of $3.50 900 is conveying
5000 gallons of water to the mine daily
and this could be increased to 100,0 900
with the present pumping capacity at
the springs. The water supply = said
10 be almost ~inexhaustible, and any
time it is deemed necessary to increase
the size of the mill there will not be any
danger of a shortage of water to supply
the additional stamps. After the ore
is first run through a crusher and re-
duced to a size not larger than a small
walnut it is convt yed to the automatic
sampler by an endless belt and then is
fed to the stamps. A 2O-mesh screen is
used and the pulgerized rock then flows
over the matchmaking tables, and that
which flows off the tables is sluiced into
a Huntington mill of which there are

The screen on the Huntington is a 30
mesh. From the Huntington the ore
runs over another plate and the thor
ougEly pulverIZed ore is then run on the
concentrating tables, there being one
Frue vauner and II Triumph for each
oatterv. During the past week five of
the stamps have been used IN Combina-
ton high grade ore and probably never
before in the history of milling was such
high grade ore run through. Alter run
ming over the matchmaking tables the
taillngs are being sluice4 mt 9 large

will be draw off, the tailingo shOveled
ont and after being dried by the sun will
be sacked and shipped. The vast ma
jority of mining men will he inclined to
smile when they read OF talllugs being
shipped to a smelter and come to the
conclusion that the fellow who wrote the
article did not know the difference be-
tween concentrates and taillnys. The
ore that is being treated from The Com.
bination at present ASSAYS from $500 to
81 900 Il ton, and it is estimated that -
per cent OF the assay value is saved by
amalgamation leaving p per cent or
from 5000 to $3.50 Il ton value to the en-
tire mass OF finely pulverized ore. AS
that is about the grade that escapes
high railway charges the company is
making money III not using the concen-
trating tables. 1t is also too high to
cyanide-at least the company will try
a lover grade of ore for that purpose at
first. The five stamps on the company's
ore are crushing about l. tons of ore
daily. 1t is found necessary to clean off
the plates every two hours, on count
of the quicksilver being loaded with gold
and not able to take up any more of the
bright yellow particles.
The other battery is working on jan
uary ore and here the concentrating ia
bles are in use and the saving made by
them will be treated by the cyanide pro-
cess. The January ore comes from the
low grade dump and samples from $25
to $50 a ton. A trial run of 500 tons will

Is to 20 tons daily.
The total cost OF the mill was in round
numbers $50, 900, and to this must be
added the pipe line outlay OF $4,000 or
a total of $3.50 900.
The New Western Reduction COM
pany's plant is located a little south and
west of town and is nearing completion.
Amalgamation, concentration and cva-
hiding will be used. Five stamps will
be ready for work early next week and
Is additional ones each weighing $40
pounds have been ordered and work Of

ing will be started in a lew days The
company has also a we'll equipped sam
pier in connection that has a capacity OF

be purchased. To each battery of stamps
