running of the big pump about three
hours a day. Thus it will be seen that
should the flow of water become much
greater it could easily be handled.
The bottom of the shaft is now down
1,2s4 feet and will be sent down as fast
as possible until the 1,500-foot point is
reached, where, according to present
plans, considerable prospecting in the
nature of crosseuts will take place. An
air lift has been installed to handle
the sinking pump, with a lift of 20 feet,
which does away with the block and
chain, thereby saving a great deal of
time and labor in removing the pump
before blasting.
Sinking in the Red Plume shaft is
progressing very favorably, the bottom
being now down about 500 feet, or 100
feet below the point where work was
resumed, which depth corresponds
with the 600-foot level of the Mizpah
shaft, at which point the shaft will be
connected with the Mizpah workings by
a crosscut now being run for that pur-
pose. The bottom of the shaft exposes
from 2 to 3 feet of quartz carrying very
low values.
Throughout the mine the usual ener-
getic prospecting and development work
has been accomplished, a total of 442
feet of new ground having been broken,
3161a in the Mizpah workings, 911A in
the Silver Top, and "a in the Red
Plume. During the past week several
of the workings on ore have shown con-
siderable improvement, the veins show
ing a marked increase in strength and
carrying good milling values. The
slopes in the older workings continue to
yield the regular tonnage, which is sent
to their 1O0-stamp mill at Millers.
The Montana.
During the past week the Montana
made a good record in the way of de-
velopment work, there having been
broken a total of 204 feet of new
ground, the most of which was on ore,
thus adding considerably to the visible
tonnage in the mine. Considerable new
work is being done in the way of open
ing up the ground, and as the forma-
ton is highly mineralized it is more
than probable that the new ore bodies
will be encountered. The older work
ings in the mine show little change from
former reports, the veins in general
maintaining their strength and values.
During the week all 40 stamps in the
mill were kept dropping, crushing a
total of 1000 tons of ore, 646 of which
came from their W mine and 384
from the MacNamara, and yielding an
average extraction of 80 per cent. Dur
ing the coming week the balance of the
MacNamara ore on hand will be treated,
after which all the stamps will drop or
their W product. The usual semi
monthly cleanup of precipitates was
reduced to bullion this week in the
c~ompany's new refinery, the milling
and pouring process occupying the
greater part of Wednesday and Thurs
day, and resulted in the production of
% bars of bullion weighing between So
and 90 pounds to the bar, in which
form the product of the cyanide tanks
is shipped to Selby's, where gold and
silver are separated, the concentrates
being shipped as formerly to the same
company for treatment.
MacNamara Sinking.
Excellent progress is being made in
the MacNamara double-compartment
shaft, which is being sent down at the
rate of 4 feet, a total distance of %
feet having been reported for the week.
The bottom of the shaft is down $40
feet below the collar, or 140 feet below
the point where sinking was resumed.
The formation shows no change, being
dacite. At this rate the S00-foot point
