\cpec1aI TO silver StaCe)
SPOKANE, WASH, March 21.-
Mines in Shoshone county, in the
Cour d'Alene district contributed
minerals of value Of $l5,275 ,O2415
of total ore production of $17,135,-
f695.9o in 1910, according to a report
compiled by R. Cushing Moore, state
mine inspector, as follows: Gold, g.
ITO fine ounces, s64,2s3.7O; silver, r.
262,271 fine ounces, $3,S13 ,579.8a;
lead, 229,950,506 pounds, $l0,34S,-
1880; copper 5,003,649 pounds, $685.
469.42; zinc, 5,995,600 pounds, $685.
1880. The production in 1909 is es-
timated at $13, ,723, JOG. The output Of
the district since its discovery in
1885 is placed at $2l00O0,OOO. Only
two properties worked to depths Of
more than two thousand feet, have
been exhausted during the last 25
years.
Inspector Moore declares that more
development work is in progress and
the producing properties are sending
out larger quantities of ore than ever
before, adding that the district has a
brilliant future, as all the mines have
as good ore bodies at depth as were en-
countered in the upper workings. I'm
proved machinery has been installed
on several properties and with the de-
velopment work now going forward
much additional equipment will be re-
quired.
The Bunker Hill & Sullivan mine
has been developed to depth Of more
than 5000 feet on the dip Of the vein.
The Standard and Mammoth is about
the same depth, which the Morning has
2,700 feet and the Hecla and Hercules
have fully 1900 feet ach, with no ap-
parent diminution in the quantity or
grade of ore. Interesting geological
conditions have been exposed in the
Bunker Hill and the Morning Mines
In the first named the vein in descend
ing is virtually paralleling the bed
ding planes of the sedimentary series,
/ in which all the ore bodies of the dis
tl'ict occur.
The Bunker Hill & Sullivan has
maintained its remarkable output
throughout the year, having produced
approximately 70,000,0o0 pounds of
lead and 1,245, 900 ounces Of silver. A
shaft has been sunk and levels opened
up to depth of 1900 feet below the
j
| than 5000 feet on its dip benesth the
apex. An additional unit of 500 tons
daily capacity is under construction to
give a milling capacity of 1900 tons.
! Wardner mine, formerly the Last
Chance, owend by the Federal Mining
& Smelling company, has operated con-
tinuously under the present manage
ment. All differences between the
Federal and Bunker Hill companies
have been adjusted, the latter secur-
ing title to all claims formerly owned
by the Federal company in the dis
trict, the Federal company retaining
possession of the Wardner mine, from
which it is permitted to extract ore
until it is exhausted, the Bunker Hill
company in return giving the Federal
company large block of its stock.
Caledonia mine a near neighbor of
the Bunker Hill & Sullivan and the
Federal properties, but on separate
vein system, has made the most re-
markable record of any property in
the Coeur d'Alene since the discovery
of the Hercules. The property. which
was located in 1885, was idle until
three years ago, and owing to the
meager geological knowledge of the
district, it attracted little or no atten
ton. It's development has demon
strated the likelihood of a number of
similar vein systems in the district.
The ore, which is of unusually high
grade in lead and silver, carrying also
on important proportion Of copper,
has been developed to a depth of 500
feet by an inclined shaft, equipped
with an electric hoist. The ores pro-
duced to date have been hand sorted
and shipped direct, the company hav-
ing no milling facilities; but with the
completion of long tunnel from
Deadwood creek, which will tap the
vein several hundred feet deeper than
the bottom of he shaft, ore can be
handled directly to the railroad, at
greatly reduced cost of operation. This
also will afford the advantage OF treat
ing the milling ore as it is extracted
from the mine, so that the profits
should be materially increased in the
future.
Stewart mine has produced during
the major portion of the year, its ore
being handled by rail to Wallace,
where it is milled in one of the units
formerly used by the Mammoth mine.
Active development has been carried
on and large reserves of milling ore
put out in sight The property also is
upon a separate vein system, but the
character of the ore more nearly con
forms to the main Wardner vein sys-
tenn than that of the Caledonia.
