TIE MINES.
GREY ROCK.

put III, connecting the face of the drifts with
the cross-cut, and the iron for the turn-table
having arrived, the extraction of ore has been
greatly facilitated. The east and west drifts
are each in about 80 feet, and are yielding
thirty tons of ore per diem, a~ssaying
about $40 per ton. Tomorrow the initial
step VIII he taken for the systematic and
proper development of this great property.
Already a half Il dozen lodges have been dis
covered on the claim. Some of them are
wide, and have produced rood ore, but
neither OF the two shafts already sunk IS
large enough to carry on explorations to any
considerable depth, and extensive hosting
machinery is necessary, if the company de-
sire to prosecute developments below water
level this could not be employed in
shafts such as those now sunk Oh the property.
Accordingly, it has been decided to sink a
main double compartment shaft. Bids for
sinking the first hundred feet have already
been invited and received, and it is expected
That Tomorrow, sinking will begin at a point
ABOUT fifty feet southeast of the new shaft
house. After a depth of 100 feet Shall have
'S'"'HSh, iClot4IS H'ii pumping Ildclllll-
cry will be supplied, and the shaft will be
continued to a depth of 300 feet. During
The sinking, no attempt will be made to ex-
tract ore, but drifts will be run below water
20 ascertain the character and continuity Of
the lodges. On reaching the 3O0-foot level
a heavy force CT men will be employed,
cross-cuts, levels and slopes will be run, and
coasters will be put into the Silver Bow mill
to enable the company to treat the base ore.
The Grey Rock is destined to prove u great
property. From the 40-foot level in the west
Shaft to the 92' foot leycl, the width of the
ledge increased from s to 20 feet of solid ore,
and there is so far 10 reason to doubt that
1t Will continue to improve in the future as it
las done in the past. The results Of sinking
$50 feet below water will therefore,. be watched
with deep interest.

lhis claim is probably a west extern sion of
the High Ore. 1t was purchased a few
months ago by Mr.. w. a. Clark for SIS, $500
but since that time 10 work has been done
until within the past few days. The shaft is
now about twenty feet deep following q ledge
of free ore of somewhat low grade. No
walls are yet visible as the workmen are ex-
tracing only about four feet of the ledge. A
few loads of the ore have been tested at the
Dexter with a very satisfactory result, and
hereafter the Tom Marshall Will I've added to
the list of paying properties in the camp.
BELL.
There is nothing Important this week to re-
port from the Bell. The lower east level IS
beng pushed ahead Oh the hanging wall side
of the ledge. and is now distant from the
shaft about 20 feet. The ore product remains
unchanged in character, ~assaying high in sill
yer and containing a high percentage of cop
per. Judging from recent developments in
the Bell it is quite safe to assert that on the
expiration of the bond arrangements will be
made for the immediate purchase of the
property.
MOOSE.
AS the lease on this property is almost ex-
PRED, and as a great deal of the surface ore
has been stopped out, Messrs. Passage IL Rice
do not feel justified in carrying on very ex-
tenSivc explorations at present. In order
properly to develop the mine the east and
west shafts should be sunk at least 100 feet
further, but for the reason stated this will not
be dome unless a renewal of the lease is
shaft, i blind shaft was started three days ago.
It a depth OF five feet a body Of 50 ounce ore
was uncovered which iii the bottom, II feet
from the surface, has opened out to 4 width
Of four feet. The lessees will probably con-
~centrato their energies N this hole until the
lease expires.
rRARI 4.
In tl" main Shaft water was struck last
week, neccssitatins a temporary suspension
Of work. Sink NJ was then resumed on the
old shaft, several hundred feet east on the
sanc ground but probably not on tie same
ledge. The Shaft is 45 feet deep and is fol
lowing Il l5-inch vein of rather high grade
ore, il bucket sample on Friday a~ssaying 40
ounces. About 90 tons of ore are on the
dump and unless water soon intrudes its ul-
welcome presence active sinking will continue
as the quality and size of the vein improve
with depth.
LEXINGTON.
The daily output continues at about Is
tons, being regulated By the stamp capacity
of the Lexington mill. The bulk of The ore
is be ny extracted from the east level. The
main shaft, TO be sunk to 4 depth of $40 feet
from a point some distance south Of the pres
ent working shaft, will be commenced about
the lst Of July and for the first hundred feet
will be sum with a wliym which is now in
course of construct ion, This shaft will
doubtless be of material benrfil to the camp
as, in the opinion of competent Judges, it will
prove the existence of 4 bonanza in 10 way
inferior to the Alice Itself.
