zinc.
The tonnage treated by the Globe.
Leadville, 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
Il
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 n heavy In
crease. The Western zinc oxide plant
at Leadville was placed in successful
operation in April and operated
throughout the year on Leadvile zinc
carbonates.
The gold output of Cripple Creek
tTeller County,, was $13.539,245. an
increase Of $1.543.129. The yield was
also $507,32S larger than the 1908
yield, which was the largest yearly
output since 1906. Cripple Creek, to
the en- 1915 has produced $272,-
$4,000. The Roosevelt tunnel con-
tinued to lower the water in the
mines, except in the Vindicat6r-I
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
Ell Paso plant was destroyed by fire |
was resumed March 2, 1915, the tun-
mel then being l7,127 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-
tion 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 a body
of exceptionally high grade ore in the
Cresson mine in December, 1914, re-
suited in greatly increased output OF
III district for the first quarter OF
II year 1915.
~ Ake County, chiefly from Leadville,
but no including the Lackawanna
Gulch u St. Kevin lode districts and
the ArkaSsas River dredge district,
produced \.2G1 900 in gold, 2,G6O.oo0
ounces of sVer, 2O,00O,000 pounds Of
lead, 1.s40,o0A pounds of copper, and
100000 poulNs of zinc, with total
value of s14,0O,O0O, against $1,571,-
451 in gold, 3.SO,S3O ounces of silver,
26,7S4,615 pound, Of lead. 2,3S2,910
pounds of copper, rs, 763,334 pounds Of
zinc, with a total ralue of $9,057,297
in 1914. Metallic eold was shipped
duripg the year from the IbeX anl
Third Venture mines. The output of
zinc carbonate was 10000, tons of 90 |.
per cent zinc. against 113,SS1 tons of
s4,3 per cent in 1914. The zinc sui
phide smelling ore and concentrating
ore combined was $4,000 tons of "a
per cent zinc, as compared with ILL.,
947 tons of 2l.2 per cent zinc in 1914.
Operations were resumed in April at
the 5O-ton zinc oxide plan-. and 1t was
operated successfully during the year
on zinc carbonate ores of 16 per cent
or less, The Pingree flotation plant
was operated on zinc-lead sulphide
ores from Leadville and Red Cliff.
The water in the downtown mines
was lowered by electric pumps to near
" 700 feet at the Penrose shaft. The
Derry Ranch dredge, below Malta, be-
gan operations in October and from
thence on regular shipments of bull
,ior were sent to the Denver Mint.
