The tonnage treated by the Globe.
Leadville. Pueblo, Durango and Salida
smelters was approximately the same
a. 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 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 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
(Teiler County,, was $13.539.245. 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
mines, except in the Vindicator-
Golden Cycle. where electric pumps
are used. Several shafts were extend
cd to the depth Of 1900 to 1000 feet.
Work on the extension Of the tunnel.

El 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
and Victor were operated steadily
with an increased output. The STRAIT
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 a greatly increased output OF
the district for the first quarter of
the year 1915.
