THE MINES.
ALICE.

o'""o " oe worked TO some extent, opera
lions are principally confined to the fourth
and fifth levels, which are being steadily
driven ahead with the usual excellent results.
The slopes, though wide, are all in ore, no
attempt being made to extract the full width
OF the vein. Crosscutting from the 7OO-foot
station has not yet been resumed, as the dis
charge pipe has not yet arrived. The two
new pumps, however, have been placed in
position, and on the arrival of the pipe, which
IS coming by fast freight, the vein will be
tapped at the earliest practicable moment.
GREY ROCK.
Operations in the new shaft, which got to
be too deep for the successful working of the
whim, are still suspended awaiting the arriv-
al OF the necessary steam hosting machinery,
which is expected in a few days. In the west
shaft on the lower level energetic work con-
tlnues and an average daily product of 80
tons of free ore is being extracted and shipped
to the Silver Eow.mill. Although not excep-.
t~ionally rich, the Grey Rock ore, from the
ease with which it can be milled and mined,
is far more profitable than refractory ore of a
much higher grade. The thousands of tons
which have already been extracted, and the
vast amount still untouched in the mine, will
perhaps mill not to exceed $50 per ton, but
this, after the deduction of working expenses.
leaves a very satisfactory margin for the
owners of the property.
GAGNON.
This mine continues to be developed with
out any material change in the character of
the ledge. The lower level running east
from the bottom of the main shaft at a depth
Of 225 feet, has been extended to a length of
le5 feet, following a we'll defined vein of
base ore, Of which about 25 tons are being ex-
tracted daily. The first class ore is being
shipped east for reduction and the second
class is treated at the Colorado works. The
obliging superintendent, Mr.. Rosenthal, YES
terday informed our reporter that sinking of
the main shaft would be resumed in about
two weeks. The present machinery is
thought to have power sufficient to sink to a
depth of between 400 and 500 feet.

The new shaft is making excellent pro-
gress and is now down ITO feet. 1t will prob
ably pass through the vein within the next so
feet, after which a rather heavy volume or
water may be expected. The hoisting gear
for this shaft will be the largest in the terri
tory. In the drift east from the bottom of the
working shaft work has been stopped for the
present in the face, and the reserve of ore on
the foot.wall side of the ledge in the drift is
being extracted. This reserve averages from
six to ten feet in thickness and is over 800
feet long, and is being token out to facilitate
stopping when the smelter shall have fired up.
The rich strata and pockets are being sacked
for shipment and the lower grade ore is &C.
cumulating on the dump.
ANsELMo.
Since last report a level has been started
from the bottom Of the west shaft which will
open up the new vein lately discovered and
which for a time was enormously supposed to
be a continuation of the main ledge. The
east drift is in - feet and the west 6 feet.
In the latter the ore body Is two feet wide
and OF apparent richness, though the value
cannot be accurately stated, as no assays OF
it have yet been made. In the west drift the
vein is not SO wide, nor does the ore look so
we'll.
In the main shaft there are no important
change to note. The slopes in the 7O-foot
level are in excellent shape and are yielding
several tons per diem.
In the lower level, 100 feet from the sur
face, some exceedingly high-grade rock has
been extracted during the past week. The
drifts are in 40 feet each way, and are being
vigorously extended. The ore body varies
from three to.four feet in width, and is we'll
defined, compact and clean. Shipments to
the smelter are made almost daily though $50
tons of second-class ore, assaying $50, remains
on the dump.
sTAR WEST.
The two shafts at a depth of 100 feet, have
been connected by a drift, Which shows a
continuous vein of high-grade ore from one
to the other. 1T varies from two to three feet
in thickness and possesses all average assay
value of 5000. liz view of the large amount
of ore opened up between this drift and the
surface 1t is not deemed necessary to resume
sinking at once, though the necessary ma
chinery will be ordered in proper season.
Instead, therefore, of exploring any further
below water level, the owners have deter
mined to Slope and without any further de-
velopment it is plain to see that they have a
long winter's..work ahead of them. That the
labor will be profitable is equally beyond dis
putc.
