PRODUCTION IN 1918

but silver, copper and lead increased.
ing 1913, according to Chas. w. Hen
derson, of the United States Geologi-
cal Survey, was SIS, S,146,916 in gold,
9,325, ,255 ounces of silver, 87,620, 1854
pounds of lead, 7,29S,2s9 pounds of
copper, and 11S, S,346,429 pounds Of zinc
| Tin terms of spelter and zinc in zinc
oxide), with total gross value of re-
covered metals of $35.449, ,298, as COM
pared with 37,32O,966 in 1912. a de-
crease in value for 1913 of 81 ,S71 ,66S,
or five per cent. There was a de-
crease Of SAL ,646 in gold, an increase
W 1,113,185 ounces of silver, an in
crease of. 12,37S,097 pounds of lead,
an increase of 19O,966 pounds of cop
per. and a decrease of 12,876,3S3
pounds of zinc. The heaviest decrease
in value was $2,439,974 for zinc, but
there were increases of s5S2,O31 for
silver and s469,394 for lead.
Cripple Creek produced 60 per cent
Of the total gold yield of the state,
with yield of s10,9O5 .OO3, as com
pared with s11,O0S.362 in 1912. The
output for IL months from Cripple
Creek seemed to indicate a produc-
tion for IL months of s11, 1874 900, but
the severe storm of December 4th
so crippled transportation facilities
that the December yield fell off
heavily. There was an increased
yield of gold bullion from custom cy-
anidation plants at Colorado Springs
and from cyanidation mills in the
district, the decreased yield being
due to a decreased tonnage of smelt-
J ing ore. The Roosevelt tunnel con-
tinued to lower the water level grad
ually. In the Vindicator and Golden
Cycle mines electric pumps were in
stalled. Lower levels were opened
in various properties.

of lead, and 93,S42,S pounds of zinc
(representing 70 per cent of the state
yield, with total vaiue of s9919.-
The output of zinc carbonate was
135, ,760 tons of 27.45 per cent zinc,
against 142.7s2 tons OF 29.2 per cent
in 1912. The production of zinc sui
phide shipped was 1886 tons of %
per cent zinc, as compared with 1o4,-
14s tons of "a per cent in 1912. 9th
er classes of ore from Leadville show
ed little change from 1912.
