THE MINES.
N'"s Notes from ihs Butte Bsnan.as.
PACIFIC,

Sooo az Aottt
men are employed who extract daily 20 tons
.. ore from which fact some idea may be had
VI '"e size OF the ore body. The slopes are
III VI On all sides as is also the drift. The
"es' uf'it Is not being advanced at present as
'ne company has no facilities for milling any
greater supply than is produced from the east
"t't' several hundred tons of ore are on the
d''mp which will average from $50 to S35
per ton. 1t is perfectly free and can there
lore be easily and inexpensively milled. The
silver Bow mill is now making a run on Pa
cific ore with gratifying results.
MOUNTAIN BOY.
From the bottom of the main incline.
which is 2lO feet deep, the drifts east and
west rave each been extended 10 feet during
The past week and are now being actively
pushed onward. The ore body, which from
the surface to the 10O-foot level did not aver
age more than a foot in thickness, is now
three feet wide, with little or no ledge mat
Ter. The ore is not, at present, of very great
richness, but yet contains enough precious
metal to leave a handsome margin after de-
Quoting all cost of extraction and reduction,
The water occasions very little trouble and
The expenses of running the mine are, there
fore, inconsiderable as compared with what
1t would be if a heavy volume of water had to
DO hoisted. On the dump are 70 tons Of excel
lent ore which will be shipped to the smelter
this week. The first load was sent yester-
day.
ANSELMO.
Work on the Shaft house having been COM
pleted, energetic operations have been re-
sumed in the mine with most encouraging
results. In the lOO-toot level the ore body
has greatly enlarged and is now seven feet
wide in the Slopes. OF this three feet assays
from $50 to $l15 per ton and the balance
between $40 and $50. Sinking In the old
shaft has also been resumed and it is now 1875
feet deep. The 2OO-foot level is expected to
be opened up during the coming winter, and
if the ledge continues to increase in width as
it has done during the last 100 leet, all i'm
mense body of ore is sure to be opened up.
The within with which it is proposed to con.
tinue the sinking of the new shaft to a depth
of 200 feet will be completed this week.
COLUsA.
Little is being done at present in this prop
erty except to widen the 16O-foot level to the
full width of the vein. by this means
enough ore has been extracted to supply the
Montana smelter, and at the same time the
mine is being put in excellent shape for the
working of the Slopes when occasion may re-
quire. The new shaft, at a depth of 100 feet,
has been connected with the east level by a
crosscut and a station has been put in. Sink
Ing will soon be resumed and the hosting
and pumping machinery started up.
The shaft house, GOxIO0 feet. is rapidly APP
preaching completion. The gallows rame
for the hosting works will be the largest in
the territory.
Active development continues and is
| great lv facilitated by the steam pump which
has lately been placed in position. The shaft
Gan inclinc) yesterday attained a depth OF Az
feet, and the vein has widencu to four feet,
double its width at the surface. The black
manganese ore, which pinched out at the
water level, has reappeared at the bottom aud
assays $40 per ton instead Of $40 as formerly.
The ledge also contains conside,ab green
chlolidrs, a picked sample of which taken
several days ago from the bottom Of the shaft
assayed $3.50 per Ion. OF course there is
very little OF his class Of ore at present, but
there is q good show of its coming III stronger:
and it is wide enough even low to add We;
materially to the average value Of the output
rlc developments on the Ophir are yeL toe
limited to enable one to form a correct pin
ion as to its future, but the lessee says lie is
satisfied with the outlook and proposes tt
stay with it, and it is known that those who
gave up the lease on the mine several months
ago because of the expense OF procuring the
necessary pumping machinery are now kick
ing themselves very energetically.
NORTH STAR.
The east and west drifts from the bottom
OF the new shaft are being pushed forward
and considerable ore is being extracted. The
west drift IS in II feet and the east consider
ably further. In the latter tho ledge is about
four feet wide, but is somewhat irregular and
broken up so that the ore body proper is not
more than two feet wide. The product assay
from $50 to $75 per ton, picked samples going
much higher. There are now so tons OF ore
on the dump, and about the same amount
has been lately shipped TO the Clipper mil
tor tire atment.
SALISBURY.
Operations are principally confined to the
stones in the east drift which are yielding
about eight tons OF ore per diem. 1t varies
in ASSAY value from $50 to $40 per ton, and i:
being shipped to the Burlington mill, wh'c'
it keeps constantly supplied.
