tue Dig mining plant OF the UnlteQ
Comstock Mines company, from the
coarse crushing to the cyanide depart
ment, is now in operation, with some
portions for a full 24-hour day, and
with every detail of the equipment OPP
Grating smoothly.
While the daily tonnage of ore now
being treated is about 1000 tons, ore
shipments are being increased gradu-
ally until the full capacity of $500
tons or more will be fully attained.
Underground, the mining end of the
project is in full operation and ore
shipments made continuously through
the haulage tunnel, ore for glory holes
now being drawn through at the sur
face located between the Imperial and
Jacket shafts.
The electric trolley haulage system
is functioning perfectly and the ore is
being transported to the mills in trains
of Il cars, 20 tons to the trip. Four
cars are dumped automatically and at
one time at the ore pocket at the head
of the coarse grinding plant. The build
Ing program at the portal of the haul
age tunnel at Comstock has been prac-
tically completed, all that remains be-
ing the finishing touches to the assay
office and hospital.
More than so mining men left in au-
tomobiles from Wallace, Ida, last Mon
day for the Broken Hill mine near
Huron, Mont. A new strike of silver
has been made at the property, which
IS $500 feet above sea level.
A new outbreak of the West Colusa
fire occurred on two levels of the
mine Wednesday, and it is still being
fought bitterly. More than 100 helmet
men are working in the fire zon in an
effort to confine the deadly fumes.
While no information would be given
out at the mine, it is understood that
the fire Is a sudden outbreak of n
that has been smouldering for several
years between the West Colusa and
Tramway. 1t was stated that more of
the present working sections of the
mine are in danger.
The old Alabama mine in the Little
Rockies is undergoing new exploration
and showing good results. The mill
is in operation on ore that is mined
during development, but no attempt is
being made to block and mine on a
large scale at the present time. The
future of the property appears excep-
tionally bright as development pro-
crosses, and the mill is expected to be
running at full capacity.
The ore of the Little Rockies in
northern Montana is gold bearing and
is recovered by cyanidation. The de-
posts are in the sedimentary rocks
of that region and are peculiar and un-
usul. The gold is supposed to be in a
state of solution in the clay-like mat
rix, as no visible particle of the yellow
metal has ever been seen. But cyanide

Sulphur-dioxide has proved to be the
right material to use in securing values
from low grade coppers. At least
that is what the bureau of mines at
Washington, d. c., claims, and the
statement is well fortified with u
thentic details from the Tucson sta
ton. 1t is state that teaching discov-
cries above So per cent have been
made in test work on ores taken from
the Big Indian mine, 80 miles south
of Moab, Utah.
The use of iron as a p~recipitant,
according to the report of the bureau,
insures a higher recovery than appears
possible by e~lectrolysis. The Big In
dian mine is a low grade copper prop
erty that is II miles from the nearest
railway point. Owing to its remote
ness from a railway and the low grade
character of its ores, it was selected
for use in these experiments.
Edmund So Leaver, metallurgist in
charge, predicts that the successful
! commercial operation of the property
is possible under the new process of
recovery. The values in the ore are
all copper, occurring as azurite and
malachite in sandstone. In Montana
| there are lots of copper deposits that
should be brought out under operation
by means of the new and cheap pro-
cess of recovery.
With the completion of the Electric
power line to the Emery mine and
mill, October /, the Zozel district,
eight miles east of Deer Lodge, will
greatly increase production. Joe
Whitworth of that city is making ar
engagements to run the Emery mill to
capacity, and it is being overhauled
awaiting the electric connections.
The force in the mine will be in
creased and Whitworth and his asso-
ciates expect the Emery to again rank
among the good producers. The Blue
| Eyed Maggie, adjoining the Emery, is
being worked by Jim Higgins, who re-
ports that he is stopping on a two foot
vein of ore, a streak near the foot
wall. more than six inches wide show
ing returns of 500 per ton in silver,
gold and lead.
A car of ore was shipped to East
Helena Tuesday. The shaft is down
II feet and with the completion of
the power line, Higgins expects to sink
the Blue Eyed Maggie another 100
feet. =,
In the same district Dightfoot and
Eagle are working the Maynard mine
and have uncovered some good ore.
They are at present sinking a shaft.
Other adjoining claims which show
good prospects are the Argus, owned
by Shultz and Peterson; the Bonanza,
owned by the Zozel estate, and the
Emma Darling, owned by George
Boothroyd. Several Butte lessons are
making negotiations on another prop
erty in this district.
The shaft of the Butte Main Range
of the Tuolumne is down to a depth
of 1900 feet. A station is being cut
or that level and when it is completed
sinking will be resumed and continued
to a depth of 2,400 feet.
According to a circular letter sent to
stockholders of the Callahan Zinc
Lead company by John Borg, president,

erty of the Galena Mining company is
