$50 feet from the bottom a crosscut was run
to determine the width of the ledge at this
point it was 40 feet from wall to wall and
carried a large quantity of high grade ore.
One hundred feet from the surface a drift to
the east is in 65 feet, all in ore streaks which
are very rich. In one place on this drift
there is 20 feet of ore.
The west drift, 1OO-foot level, is in 45 feet,
running through a body of very good looking
ore some OF which is very rich.
About 1000 tons of ore have been extracted
from this mine above the 100-foot level.
The lowest lot worked went about So ounces
and the highest in the neighborhood of 800
ounces. 49, .. .. .. .L... ....
The AIoultOn Mine. ..
Owned by w. A. Clark, lies directly west of
and adjoins the Alice mine. A shaft has
been sunk on what is called the North Spur
to a depth Of Is feet. The east drift from
the bottom is in about 80 feet, all in ore. As
the ledge was never crosscut on this level 1t
is impossible to form any opinion as to its
width.
The west drift, 71-foot level, is in As feet,
showing about the same character of ore and
vein matter as the east drift.
A large quantity of ore has been extracted
from above the 71-foot level which worked in
the mill from 30 to 100 ounces in silver and
from Sc to SIP per ton in gold.
At the time sinking was stopped the water
ever, probably drained the ledge and there
would be little difficulty in sinking now.
The Pollock Mine.

one mile northeast of the Alice hosting
works.
A shaft is down 30 feet following a streak
of ore which although narrow is of a high
grade. 4 lot of ore taken from there worked
120 OF. in the mill. West of the shaft, on the
ridge, the ledge is very strong and will aver
age about 4 feet IN width. The ore taken
from here worked so OF. The pay streak,
however, is very narrow not averaging over
l0inches. Should the crevice fill with pay
ore this would be a very fine piece OF proper
ty. They expect to resume operations soon
and prospect the ledge thoroughly, the sur
face indications would certainly justify the
expenditure of a considerable sum of money.

which cut an enormous body of low grade ore
about 40 feet in width. A shaft was started
in the groupings at a point where the ledge
about 20 feet wide and IS now down
20 feet in ore all Of the way which is how
ever, Of rather a low grade and carries a
heavy percentage OF manganese. No cross
cut having beeu run from this shaft it is i'm
possible to determine the worth of the ledge.
The great size of the ledge on this mine aud
the fact that all of the ledge matter carries
more or less silver gives the property a con-
delable value as should the ore increase but
very little in richness, it would be a remark
ably productive piece of ground.
The Black Bear Mime,
Owned by McDermott 81 Co., is situated
about 2 miles north of the Alice and adioins
the Thick Herder mire on the west. The
main shaft is down IS feet, 5 feet of which is
used as a stump, showing but little ore. At a
depth of so feet a station was opened.
The east drift, so foot level, is in about Is
feet at the point where it was started a very
nice looking streak of ore was encountered
and followed for about so feet; here it
pinched down to a mark, and the next 90 feet
was run through ledge matter with some
narrow streaks of ore showing occasionally,
then ore began to come in, and at present the
face of the drift is looking well, showlng3
feet of ore, some Of it, l am told, of a very
high grade.
The west drift, 50 foot level, was run about
So feet, when, following a streak of good ore
ranging in width from 1 to 5 feet, a s.break"
in the ledge was encountered. After consid-
cradle aimless labor it was determined that
the ledge had broken over to the south, and a
crosscut was started in that direction, which
is now in about IS feet, running through
granite and crossing several large streaks of
ledge matter. The face is now in a mass of
granite vein matter and tale. Twenty feet
from where the crosscut was started a streak
OF quartz was encountered, some of which
assayed very well, and a drift has just been
started east at this point, the face of which
shows some considerable fair looking ore it
has consequently been determined that this
is the ledge, although it seems to me exceed
ingly doubtful. Still as the walls in this section
of the country do not appear at any time to
be very we'll defined, this may be the same ore
body which showed before the break was
encountered.
Considerable ore has been stopped out above
the so foot level, some of which was of very
high grade. They are now working about 10
men and extracting a small quantity of good
ore. At the
Work is still suspended on the main shaft, it
being deemed useless to continue sinking at
present as the ore has changed from free
milling to copper, in the bottom.
Drifts were started during the week from
shaft No. 2, east and west, at the point where
the ore changes from free to base. The east
drift isin about 9 feet. showing a ledge Z feet
in width; some samples, taken from this drift
yesterday, resulted as follows: Free ore, 100
ounces base, 101 ounces in silver and 81 per
cent. copper. -.. ..r.....0 . g..
In the east stope from shaft No. 3 they are
taking out about 8 tons of free ore daily as
little base ore as possible is extracted at pres
ent, there being no sale for it. At the

Sinking has been suspended in the main shaft;
