THE MINES.
What the Developments Of q Week have
Uncovered.
Moose.

Operations continue active. Work in the
face of the south drift has been stopped for
the present, as the line of the next claim has
been almost reached. The Slope midway
betw the face of the drift and the vertical
shaft has made connection with the incline
and an increased body of ore is now being
extracted. The vein at the point of connec-
ton was three feet wide but its value is less
than that taken from the face of the level.
1t mills only seventy ounces. Within the
past few days work onthe bottom of the level
on a line with the incline has been commenced
posed to be about forty feet distant. After
this the vein will be worked by underhand
stopping tween this point and the main shaft.
A cut several feet deep has already been sunk
exposing a foot vein of $500 rock and about
eighteen inches OF second-class ore. In the
west level, which is intended to make connec-
ton with an old shaft $50 feet distant, good
progress is being made. A foot of low grade
manganese ore, carrying about thirty ounces,
is being followed and in several places large
pockets of it have been found. The ere in
this end of the level bears a strong resem-
blance to that which the Magma Charta is now
yielding, which fact, in the opinion of the
~lessees, indicates that the Moose IS a large off
shoot of that mammoth ledge. About one
hundred tons of carefully sorted ore are now
on the dump which will be soon shipped for
reduction. The
Grey Rock
Continues 10 ship about twelve tons per diem,
though the base ore is piled on the dump.
Work on the 70 foot or lower level is active
its length now being 100 feet. 1t is still pen
etrating a mass of solid base ore of unknown
dimensions, Carrying forty ounces in silver
per ton. 1t is an ore which can be easily
milled by roasting, and on the erection of a
furnace in the Silver Bow mill there is no
doubt that the mire will become one of the
largest producers of the district. The
Mamie.
Located north east OF the Cora,ls lately show
ing up to good advantage. The shaft has at
tanned a depth of forty-two feet, and shows
in the bottom a three-foot vein of ore carry
ing from forty to fifty ounces in silver.
Exactly what is being done in this mine is
producing a considerable quantity Of high
grade copper ore, which is being packed ready
for shipment. The
Rock Island
Owned by Hickey and Stewart,is being open
ed up with vigor. Three shafts are being
sunk. The west shaft under lease to Hall
and Lynch is not looking very we'll at pres
ent, but the boys are confident of striking
it lower down. The next shaft east is under
lease to Glenn and Cheesman, who on Fri
day at the bottom of a forty-foot vertical
shaft uncovered a two-foot body of fine look
ing free milling ore. No assays have yet been
made, so it is impossible to state the value OF
the find though there is little doubt that it
will prove a profitable one. In the third
shaft, which in the opinion of som is on 4
different ledge from that on which the other
two are sunk, a depth of sixty-two feet has
been attained and a level run. The ore vein is
from two and a half to five feet thick and is
yielding eight tons per diem, the assay value
being from $35 to $40 a ton. Between nine
ty and one hundred tons of ore are one the
dump. On the
Burnett
Fifteen men are employed. There is no per-
ceptible change in the aspect of the mine.
The level running east from the 25O-foot tun-
mel is--being pushed rapidly ahead and Is in
solid ole of which a nine-toot breast is being
extracted. Several cross cuts haye been run
on this level, and at no place has the ore
body been found less than eighteen feet wide.
Although it is not high grade ore, it pays we'll
for extraction. At present no blasting is nee
essary, two men ON each shift having no diff
Guilty in breaking down from fifteen to twen-
ty-five tons per diem. The level from the
bottom of the Wine in the west level is no "
in. about fifty feet and is still being pushed
forward. The ore is not very high grade ow-
ing to the proximity of the water level, but
the wonderful size and length Of the ledge
argue we'll for its quality at a greater depth,
where according to the Clayton theory, Ger
tain forms of the silver leached from above
have been deposited. The Burnet Is now
producing about thirty-fve tons of ore daily,
and is keeping two mills, the Centennial and
Dexter, in operation. Mr.. Clark, Of the lat
ter mill, is now working up a 1000 ton lot of
ore from the mine and will probably cont ract
for some more.
Clear Grit.
Thu sixty foot level in this mine was ex-
tended about forty feet west of the working
shaft by the lessees last fall, and left with the
