COLORADO'S 191 8 metal PRODUCTION
OUTPUT OF OVER
GOLD DEcREAsED SILVER. LEAD INCREASED

= Washington.-The output Of Colo.
.hado mines for eleven months Of 1913
with an estimate for December. ac-
cording to preliminary figures by
Charles w. Henderson, Of the United
States Geological Survey, shows pro-
duction Of $18.395, 900 in gold, 9,150, 900
ounces of silver, S5,500,0oO pounds Of
lead, 7,G34,000 of copper, and 129.6s0,-
600 pounds of zinc Tin terms of spell
ter and zinc in zinc oxide), with to-
tai value of $36,200. 900, compared with
$37,320,996 in 1912. This shows de-
crease of 100000 in gold. an increase
of 100000 ounces Of silver, an in
crease of 100000 pounds of lead, an
increase of 100000 pounds of copper,
and decrease Of 2,540,000 pounds Of
zinc The heaviest decrease in value
was s1,7S2 900 for zinc, and there were
increases of $4,000 for silver and
s377,000 for lead.
The tonnage treated by the Globe,
Leadville, Pueblo and Salida smelters
showed an appreciable increase for
the year. An increased tonnage was
also shipped to the Murray, Garfield
and Midvale plants in Utah. Cyanide
precipitates were shipped to Omaha.
The United States Zinc Company's
magnetic plant and smelter at Pueblo
was operated steadily.
The output of Cripple Creek
showed an increase Of $176,000 in gold.
The Roosevelt tunnel continued to low
er the water level gradually. In the
Vindicator and Golden Cycle mines
electric pumps were installed. Lower
levels were opened during the year.
The Golden Cycle and Portland cya-
nidation mills at Colorado Springs
were operated steadily, with an in
creased output. Cyanide mills in the
district also made an increased yield.
The Standard chlorination and cyanid-
at,on plant at Colorado City was idle,
but the Union cyanidation plant at
Florence was operated part of the year
on old tailings. The tonnage OF smelt-
ing ore from Cripple Creek decreased
slightly.
Value Of LeadviIIe output Declines.
Lake county (chiefly Leadville, but
for 1918 including the Lackawanna
Gulch districD produced $9S1,416 in
gold, 100000 ounces Of silver 2,000.-
900 pounds of copper, 2S,00O,00O
pounds of lead and 9s,00O,000 pounds
of zinc, with total value Of 100000
900, as against 81, 1,7sO,131 in 1912. The
output Of zinc carbonate was $4,000
tons Of approximately 27 per cent zinc,
against 142,7S2 tons Of 1912 per cent
zinc in 1912. The production Of zinc
sulphide shipped varied little from the
1O4,14S tons Of "a per cent zinc In
1912. The zinc carbonate ore was
treated at smelters in Kansas, Okla
homa, and Wisconsin and the zinc sui
phide was treated at the Empire Zinc
Company's magnetic separation plant
at Cafion City, at the Western Chem
ical Company's wet concentration and
magnetic separation plant at Denver,
at the United States ZINC Company's
magnetic plant and smelter at Pueblo,
and at the zinc oxide plant at Coffey-
Vile, Kans.
