The tonnage treated by the Globe,
Leadville, Pueblo. Durango and Salida
smelters was approximately the same
as in 1914. Increased shipments OF
copper ore we're made from Rico to
plants in Utan and copper matte was
shipped from Ouray to Utah. Cyanide
precipitates and copper ore were
shipped to Omaha. Some Rico ore
was shipped TO San Pedro. New Mex.
leo. The mating plant at Ouray was
operated during the greater part OF
the year. The tonnage treated at the
United States Zinc Company's mag.
netc-wet concentration mill and smell
ter at Pueblo showed a heavy In.
crease. The Western zinc oxide plant
at Leadville was placed In successful
operation in April and operated
throughout the year on Leadville zinc
-carbonates.
The gold output of Cripple Creek
tTeller County,, was s13,539,245. an
increase of s1.543.129. The yield was
also $507,32S larger than the 1908
yield, which was the largest yearly
output since 1906. Cripple Creek, to
the end Of 1915 has produced $272.
$4,000. The Roosevelt tunnel con
tinued to lower the water in the
s,, ha
Golden Cycle. where electric pumps
are used. Several shafts were extend
ed to the depth OF 1900 to 1000 feet
Work on the extension of the tunnel
stopped November 4. 1914. when the
FL Paso plant was destroyed by fire
was resumed March 2, 1915, the tun
mel then being 17,127 feet long. To
ward the end of the year the tunnel
was approaching the Elkton property
and the flow was in excess of $4,000
gallons per minute.
The Golden Cycle cyanidation mill
at Colorado City and the Portland
cyanidation mills at Colorado Springs
nnd Victor were operated steadily
with an increased output. The Strat
toms Independence mill was included
in the sale of the mine to the Port
land Company. The Union cyanida
ton plant at Florence was idle and
the smaller plants in the district were
not as actively worked as heretofore
The tonnage of smelling ore Increased
appreciably. The discovery of body
of exceptionally high grade ore in the
Cresson mine In December, 1914, re
suited in greatly increased output o
the district for the first quarter o
the year 1915.
Lake County. chiefly from Leadville
but also including the Lackawanna
Gulch and St. Kelvin lode districts ant

in 1914. Metallic gold was shipped
during the year from the Ibex AM
Third Venture mines. The output o
J., zinc carbonate was 10000 tons of 2.
per cent zinc, against 113,SS1 tons o
!. 24.3 per cent in 1914. The zinc sui
? phide smelling ore and concentrating
ore combined was $4,000 tons of 9.

947 tons of 2l.2 per cent zinc in 1914
Operations were resumed in April a
the 50.ton zinc oxide plant. and 1t wa,
operated successfully during the yea
on zinc carbonate ores Of 16 per cen
or less. The Pingree f1otation plan
was operated on zinc-lead sulphid'
