0wYHEE COUNTY MINES
From State Mine Inspector, Robt.
NJ Bells Report for, 1905.

west corner of the state, still continues
the most prominent precious metal
producer, and largest employer Of min
ing labor in the state, next to Shoshone
county, the old bonanza mines of Sill
yer City and DeLamar forming the
principal source of bullion.
A good ,isal of development work
was done aud undertaken, however, on
other properties IN this famous old
mining section. and the future looks
bright, with the promise of continued
and increasing production.
TRADE DOLLAR CONSOLIDATED NINE
The Trade Dollar Consolidated vein
enjoyed one of the banner years of its
history in the matter of production,
and it is probably in better physical
condition today, with more ore blocked
out ahead than it ever has been since
the consolidation or before.
The company continues to carry a
force of 225 men in niue and mill.
There was over 5000 feet of straight
development work accomplished dur
ing the year, in addition to the ore
production, and a reserve of high grade
mineral blocked out and undercut that
guarantees the continued operation of
the mill for tSo years ahead. In addi-
ton to this, and extensive area of prob
ably very productive territory was
proven.
DEWEY Tunnel The great Dewey
Tunnel of the Trade Dollar Consoli-
dated property is now in 1880 feet
from the mill level with maximum
face depth of 1,700 feet, and the rich
values of the mine have been developed
down as low AS this level. Electric
power is employed in the operation of
this mine aud mill in almost every de-
partment, and its application is re-
duced to fine system
The milling costs have been reduced
to $3.50 per ton, with saving of SO 4-l0
per cent. The ore is white quartz, con
tanning copper-iron pyrites and silver
sulphide minerals. The proportion Of
values is about "a silver to ID gold
The plant is of 20 stamps. wet crushing
aud concentrating, which saves about
q of the values, and the tailings are
amalgamated ip pans and settlers with
out further grinding and by the addi-
tion of little blue stone, salt and
mercury with steam heat. About q of
the value are saved in the concentrates
which are shipped to the smelters, and
the average value of the ore treated
during the year was something over
$50 per ton.
The great tunnel on this mine has
proved big success in facilitating its
drainage and economical operation, to
gether with demonstrating the contin-
uity of the ore to great depth. 1t is
true that as far as the vein has been
explored at this deep level the ore
shoots are not so continuous as in
some of the levels above, but they
nevertheless show a connection of rich
mineral through TO this level and
afford new drainage surface to sink
from with the prospect of remineral-
ization and more extensive distribution
of mineral at still greater depth, as was
experienced in the great Bunker Hill
drain tunnel in Shoshone county.
DEL-MAR MINE. E.-The old DeLamar
mine, five miles below the Trade Dol
lar, on Jordan creek, continues in
splendid physical condition. 1t dis
continued the production of ore on the
18th of August for the purpose of in
stalling new milling plant. A con-
siderable force of men we're kept on de-
velopment work in the mine, however,
and it's ore reserves of the quality
handled during the past three or four
years are reported to be extensive at
this date, and the continued successful
and profitable operation of this great
mine is practically guaranteed for sew
eral years by the action of the manage.
ment in rebuilding the mill, as the we'll
known conservatism of the company
owning this property iusures this sup
position.
The new mill is expected to be in
shape for operation at an early date
1t includes several modern improve
ments that are expected to reduce the
cost of handling the ore and increase
the percentage of saving, especially OF
the silver values. The great mill tun-
mel is being prepared for reopenIng-
