western part Of I-enlhi county, Ida.
which was described cit length in The
Butte Miner of recent date. should
prove TO be true. there has been dis
covered to the world what viii eventu-
ally become one CT the mos. profit
able and popular mining camps |he
world has ever known.
This camp was first discovered by
Bannock Indian 1hree years ago this
fall He was accompanied by Mr. r.
Bell, who is now sojouEuing in this
city, a guest at the Cullen, and who
was the first to investigate the In
dams find and located the first claim
in the new camp.
Mr. Bell was seen by a Herald re-
porter yesterday, who gave him the
following interesting facts relating to
the progress of the new camp since its
discovery.
The district is located 80 miles west
of Salmon City, the county seat Of
Lemhi county, on a tributary Of the
Salmon river and since the fail OF 1894
when the new district was first organ
lied. there has been 60 full mining
claims located in one block covering
about five miles in length on the prin-
cipal mineral zone, and over a mile in
width, adj of which have a good surface
showing of mineral.
The formation is a black mica schist
and soft crumbly granite, cut by dykes
of various colored igneous rocks, which
in many instances run in contact
,fg1, 1,a1-
northwest by southeast, and stand at a.
very steep angle in the formation. The
veins vary from a foot TO so feet thick
ard are usually filled with a soft sandy
quartz gangue that pans we'll in free
gold at the surface. but which rapidly
turns base as depth is attained.
There seems to be three principal
parallel courses Of mineral that can
be traced across The country for miles
with its lateral extent still underlined
The best developed property in camp
is known as the Uncle Sam group
which is now under bond and lease TO
Mr.. ]. o. Swift of Haley. Ida. This
group consists CT five full claims,
which carry three distinct veins of
mineral, but most of the development
is on the north vein which is opened
UP by an adit tunnel $50 feet in length
and a raise Of 70 feet, all Of which is
driven On ore, and the tunnel at pres
ent has a face depth of $50 feet This
work cost 81 per foot TO drive 1T and
exposes 100000 worth of ore. which
has an average value of abouI $40 per
ton in gold and 25 per cent. copper.
The rich mineral seems to stand in
chutes 40 to go feet dong and four feet
Thick OF bornite ore. very similar to
chat found in the mines Of Butte Nont.
"a massive blue suiphide of copper
the intervening spaces between the
same kind Of mineral. which Will make
a fine concentrating ore. and runs from
10 per cent. copper and SOC. per unit
IN gold. This concentrating ore IS
proved by cross cuts TO extend into the
hanging wall for 80 feeE.
Mr. Swift has started a second adit
tunnel on the vein 200 feet lower down
the mountain, which he intends TO
drive in 400 feet, when it viii be even
with The face OF the upper tunnel, and
II is estimated will add to the measur-
able reserves in sight at least another
Si,0e0,000 worth of mineral that is likely
to be of better quality and higher
grade per ton than in the tunnel above.
The natural advantages for the rapid
and economical development of this
property could hardly be excelied. The
vein IS n contact fissure which stands
nearly vertical in the formation and
COURSES sCuarely into The face of a very
steep mountain. A tunnel started in
on the vein at the foot of tire mountain
and driven in 5000 feet would have a
face depth OF about 1900 feet under a
point on the vein where II crops
through TO the surface five feet thick
and carrying 5 per cent. native shot
copper and So Der ton in gold, besides
a pay streak Of high grade GRE ten
inches thick that runs as high as so
per cent. copper and Sos per ton in
gold; and between this point and the
foot of the mountain, along the course
OF the vein. rich float ore and groupings
can be found on every 100 feet, ildi-
eating that such a tunnel would pass
through a succession of rich ore chutes
and expose one of she most phenogl-
email c0ppar-go.d zones in the world.
To give an idea of the magnitude and
possible future OF the camp Mr.. Bsil
states that there is at least half a
dozen other groups of claims in the
camp within two miles of the one just
described that have equally as fine a
surface showing and which promise to
prove up as well when development and
depth is attained.
One Of these. the Brown Scar crouD,
has a cross-cut tunnel driven through
the vein at a depth Of so fec: belew
the surface, which exposes a body OF
fine concentrating ore 100 feet thick.
which averages 3 per cent. copper and
s. per ton in gold. and that also car
