THE SHELTER AT VEISER
Prospects Of Proposition Which Would
Meet Great Need.

The Salt Lake Tribune of Monday
contains the following, which shows
how interested in this county MIN
ing people are and how quickly any
new districts tributary to Weiser will
attract attention:
There are so many people turning
their attention toward the new cop
per mining regions along the Snake
river in western Idaho, that much
machinery and material is going over
the railroads into that section. The
Seven Devils is 100 miles north of
Weiser, while at the southerly end of
that great mineral belt lies district
which seems destined to figure as one
of great importances in the future,
which is called Iron Mountains, on
occount of the large deposits of
valuable iron ores which outcrop on
it's summit and sides. An old camp
called Mineral has existed for many
years at its base, near Snake river,
but these mines were principally
silver mines and have been closed
for several years. A new copper
camp on the east slope of Iron mount
ain is now coming to the front.
Iron mountain, which is about two
miles east and southeast of Mineral,
rises to about 5000 feet elevation, and
its apex shows large cappings of iron
ore. The formation here is granite
porphyry, but on the northeast slopes
of the mountain are series of paral-
lei contacts of porphyry and crysal-
lized lime. The contacts are highly
mineralized, and at several points
the surface discloses large outcrops
of soft, porous, oxidized iron, or
"gossan, which turns into deposi,
of iron and copper pyrites, with 6
showing of carbonate ore now ant
then impregnating the ledge matter
for distance of twenty-five to fifty
feet, and possibly 100 feet in som'
cases. These large bodies of sui
phides and oxides will probably range
from 25 to 45 per cent in iron, 3 t.
30 per cent in copper and from ST tc
81 in gold and silver per ton.
The country on the east slope O.
Iron mountain at the head of Mann
creek is we'll supplied with timber
water, etc. The veins on the eas
slope of Iron mountain in the nev
copper belt dip to the southwest to
ward the center of the mountain
The principal feature of Iron mount
ain, it is now generally believed, vii
be the immense deposits of iron ant
copper, the latter coming in whereve
any depth has been gained, the irol
steadily changing into copper where
ever the large iron cappings hav
been opened. There is such stron
showing of copper under these larg
iron deposits that mining men ar
fastening to get foothold on lro
mountain and they are figuring o
plans for timbering under the mount
ain to cut into what may prove to b
some of the largest copper deposit
of the Northwest The Iron mount
ain is located upon the great miners
zone which extends through til
Heath and Seven Devils mountains
and its close proximity to the raj
roads at Middle valley and Weisel
with good wagon roads to the latte
point, makes it very attractiN
mining camp. A number of minin
men who have just visited Ire
mountain pronounce the surfat
showing and the formation, with tt
lime and porphyry contact vein
capped with large deposits of oxi
lied iron, as the most attracti'
