Colorado metals for eleven months of
1916. with an estimate for December,
from data compiled by Charles w.

The tonnage treated by the Globe,
Leadviile. Pueblo, Durango and Salida
smelters was approximately the same
as In 1914. decreased shipments OF
copper ore were 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 10 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
netic-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 outpr. OF Cripple Creek

increase OF s1.5s3.129. The yield was
also s507.S2S larger than the 1908
yield. which was the largest yearly

The Golden Cycle cyanidation mill
at Colorado City and the Portland
cyanidation mills at Colorado Springs

with an increased output. The STRAIT

in the sale of the mine to the Port.

tion plant at Florence was idle and
the smaller plants in the district we're
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 of
the district for the first quarter of
the year 1915.

but also including the Lackawanna

during the year from the Ibex and

zinc carbonate was 10000 tons of 22

was operated on zinc-lead sulphide
ores from Leadville and Red Cliff.
