washinRton.-The output OF Colo
sado mines for eleven months OF 1913
With an estimate for December. &C
eording to preliminary figures by
Charles W. Henderson. OF the United
States Geological Survey, shows pro
duction OF 1895, 600 in gold, 9.1S0.o00
ounces OF silver, s5,500,000 pounds OF
lead. 1854. 900 of copper. and 129.6so.-
900 pounds OF zinc Tin terms OF spell
tsr and zinc In zinc oxide), with TO-
tai value of $40 ,20o. 900. compared with
e37, ,320,996 in 1912 This shows de-
crease OF 5000. 900 in gold, an increase
Of 100000 ounces Of silver. an In
crease of 10,3O0,OOO pounds OF lead, an
increase OF 100000 pounds OF copper,
and a decrease Of 2,640.o00 pounds OF
sine. The heaviest decrease in value
was 1872 900 for zinc, and there we're
increases OF $4,000 for silver and
4377,oO 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 we're 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 s176,oo0 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
we're operated steadily, with an in
creased output Cyanide mills in the
district also made an increas sed yield.
The Standard chlortnation and cyanid-
atlon 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 LeadviIle Output Declines.
Lake county (chiefly Leadville. but
for 1918 including the Lackawanna
Gulch district) produced $9Sl,416 in
gold. 100000 ounces OF silver, 2,000.-

Of zinc, with a total value Of $l0.000,-
900. as against 311, ,7s0,1S1 in 1912. The
output OF zinc carbonate was $4,000
tons Of approximately 81 per cent zinc,
against 142,7s2 tons Of 29.2 per cent
a. no of yiu
sulphide shipped varied little from the
1O4,l4S 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 Canon 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.
The San Juan region Of Dolores, La
Plata, Ouray, San Juan and San Mi
guel counties produced s4,116,000 in
gold, 2.s47 900 ounces OF silver. 21,165,-
900 pounds of lead, 3.630,000 pounds
