SAL Ian t. Idu. lI.--1H mere has
bene Miserable interest shown in
eastern Utah. both from a geological
and commercial standpoint, says a
of the Mininw World.
This district is reached from Thomp-
sons Springs. Utah, on the Denver
a Rio Gr4nde railroad by way of
Moab. abont SIS miles by stage, or
from PlacerviI1e, Colo, on the Rio
caande Western railroad, about the
same distance.
These deposits were discovered as
early as 1882 and specimens of ma
tive copper. brought to LeadviHe
Indian property by an old prospcetor
with his pack train. The various
properties have continued to change
hands with varying success until now
when several strong companies have
undertaken their development.
The Cashin mine. situated about rs
miles northwest of P1acerville, Colo,
has been commented upon by S. F.
Emmons in bulletin No. $50 of the
IL. S. geological survey He states
that the product from this mine to
Gate, of copper which averaged 12.5
per cent and of silver which averaged
lS4 ozs. per ton, has been 2,067 tons.
Some shipments have been made CIV
ing returns as high as 512 ozs. sill
yer per ton. Another shipment goes
SO per cent copper and ~ ozs. silver
per ton. The silver values run irreg-
ularfy in the various forms of cop
per. Masses of native copper occur
in the koain in the 500 foot level.
One block of native copper was found
which weighed 500 pounds.
The various metallic minerals are
chalcacite, bernite, native copper,
malachite and azurite. Beautiful
crystals of these minerals are found
at various times either forming or
already formed on the walls of the
mine workings.
Various processes have been tried
to treat the ore from this mine. The
Russell teaching process was once
used to extract the silver by means
of weak solution of hyposulphite of
OF soda. This process extracted SO
per cent of the silver value, but was
too expensive for copper extraction.
Thirty-one hundred tons of ore, av-
eraging 3.5 Ter cent copper and 2S
ozs. silver. were treated by this pro-
cess at the mine. A small smelter
was also erected, iron for fiux in the
form of pyrites being shipped from
Ophir, Colo. Coke for fuel came
from ovens % miles east of the smell
Ter. The copper matter carried high
silver values.
The next largest property in this
section is the Big Indian. 35 mills
of Moab There have been
| several repofts made on ms property
I all favorable as regards the ore nj
reserve. The question is how to treat
! the ore economically. The Big In
dian property is being financed by
wv d. BOhm and others of Salt Lake
4 City and New York The property is
|. being paid for on installments, and
while the total price is about $780,
600 for the property alone, the plant
that should be installed will cost
NEARLY 100000 This property is
being managed by B. W. Todd, who
has had considerable experience in
copper mining in Montana.
! Another property of value is owned
by the Lisbon Valley Copper COM
lpany, situated in a narrow valley OF
the same name, some 5 miles south
least OF the Big Indian mine The lis
bon Valley property has recently been
taken over By Denver people. who are
energetically developing it. There
are two distinct beds of copper car
Donate on this property, each 25 feet
thick dipping at about 35 degrees.
An inclined shaft has been sunk
nearly 100 feet on one of these beds.
Samples taken across an Is inch
ST. eak Of ore average Ill per cent
copper; the remainder of the bed av-
erages per cent The two beds are
