M1ssou1A, Aug. ls.-[Special. Work i.
rapidly progressing on the Iron Mountain
concentrator. A carload Of machinery ar
rived last Tuesday and the foundations are
prepared so that it can Immediately be
placed in position. Mr.. La CrosiA, whc
has charge of its construction, says the mill
will be crushing ore by Oct, 10.
On Deep creek the development during
the week has been very favorable. The
tunnel on the May Day has been driven
about ten feet and continues to show a
strong vein of galena.
On the United States Treasury develop
ment is continued with two shifts as here
tofore.
The Little Anaconda tunnel has now
reached u point vertically under the shaft,
and a raise is being made which will CON
neot tho wo. A crossous from the tunnel
recently cut a fine vein of galsna. fourteen
inches in thickness and assaying high both
In silver and lead.
From Spring Gulch considerable ore is
being shipped. The keystone now en-
ploys twelve minesr and is shipping a great
deal of high grade ore. The o. r. d.. N.
tunnel has cut a small flow of water which
10 thought to indicate the near approach of
the main vein. The streak of gray copper
ore which was struck some two months
since has been drifted on each way and has
shown up we'll, eight tons of good grade
of ore having been extracted. This will
soon be shipped, and also several carloads
of screenings and second class ore, which
are ON the dumps of the old shaft. The
main tunnel is now in about $50 feet.
From Thompson river, 100 miles.snorthwest
of Mlssoula, Superintendent Ward Of the
Buckeye, reports o strike of three feet of
high grade ore In the new lower tunnel.
Considerable high grade ore has been
shipped from this mine, and this tunnel
will penetrate the mountain FOG feet below
the old workings.
Phillip Runyon, who has charge Of the
hydraulic placers on Windfall creek, fifty
miles west of Missoula, has been town for
the past two days and reports very favor
ably on the property. The company is
using two fumes, one on each side of the
water for both. In the fall, however, only
one can be used at a time. The fumes are
thirty inches wide and have a grade of
eight anG a half inches to the rod, each
using about 500 inches of water. The
north fums is 1926 feet in length and the
last fall and this spring. The lumber was
sawed on the ground with whip saws. At
present a six-inch pipe with eighty foot
vertical pressure is used, but the company
contemplate next spring putting in d four
taen-inch iron pipe with a little giant
nozzle and a derrick with which to handle
the large boulders. The bank varies from
thirteen to twenty-five feet in thickness,
from five to six feet of which is the pay
gravel laying on a clay bedrock and aver
aging about five cents to the pan. Four
hundred and fifty feet farther up the gulch
the flumss will touch the true decomposed
granite bedrock. The company own eighty
acres below the iume, twenty acres of which
are used as dumping ground for the fumes
now in use. Above the fumes they own
sixty acres, which can be worked by the
fumes now in. The gold from this gulch
sells at the banks for $1S.75 per ounce.
