The report Of the mineral produce
s23.5oo,0oo, according to the estimate
just received Of the United States Geo
logical survey. This figure is $3.50, 900
I less than that of State Mine Inspector
/ Bell, published in the last issue of The
Miner. Mr.. Bells estimate was based
on actual figures for ii months and a
4 close estimate made for the month IF
December very near its close. Being
in closer touch with the Industry than
the geological suryey,-it is probable
! that Mr.. Bells figures are more nearly
correct, and that complete data will
bring the geological survey figures to
practically the same amount The es-
innate of the latter is here given in

ldaho's Mineral Output. *
In 1913 the metal mine output OF
Idaho was so much increased that the
total value exceeded that of the record
year, 1906, according to preliminary
estimates Of c. N. Berry, of the United
States Geological Survey. The value
of the gold, silver, copper lead, and
Iziac mine production was over $235O0,
600, an increase of over $2,00o,000, ar
nearly 10 per cent. Record productions
were made in silver, lead, and zinc,
and substantial Increases were made
IN, nf nh rr1J ~,
remained close to the Yield of 1912, the
figures for 1913 being $1,373,0O0. The
gold yield from quartz mines. espec-
tally the De Lamar mine, which was
closed IN the last part Of the year, con-
tinued to decrease. To compensate for
this loss the gold output from dredg-
ing continued 10 increase and that
from copper ore was greater since the
Lost Packer snelter was operated
Zig Increase in Silver.
1.-THE mine yield Of silver output In
creased 20 per cent, from S,294,745
ounces in 1912 TO about 100000 ounces
in 1918, large increase even over the
previous record output Of 1906. In
silver output the state, which in 1918
had value of nearly $6,00O0o0 was
only exceeded by Nevada, Utah, and
Montana. Nearly all this silver was
derived from lead ore and Concentrate,
shipments of which were unusually
large. Another feature which account
ed for this record output was the large
production from the Greonhll- Clove-
land mine near Mace and the Hercules
mine at Burke for the mines of Lee
lande district are notable for high sill
yer content.
Great Gain in Copper,
"The copper output from Idaho
mines increased from 7,492,152 pounds
in 1912 to about 9,312,0O0 pounds in
1913, an increase of over u per cent
The three main factors in the copper
output We're the shipments of crude ore;
and concentrate from the Snow Storm
mine at Larson, the yield of copper
ores from the Empire Copper property
at Maclsay, and the copper matte pro- i
duced at the Lost Packer plant at
Ivers. Increased yield was made from
all these properties and dividends
were paid by the first and last. Cop
per was also recovered from the lead
ores of Lemhi and ,Shoshone counties.
Other copper properties are being OPP
ened in the Hunter district .of Sho-
shone county A deposit Of interest
was that developed by the National ,
Mining company, which began the
erection of large mill in which the
flotation process will probably be !
used.
Lead the Big Factor.
