year. An increased tonnage from Col
orado was shipped to the Garfield.
Aidvale, and Murray plants in Utah.
Cya:.ide precipitates and ore were
shipped from Colorado to Omaha. The
United States Zinc Company's mag
netic plant and zinc smelter at Pueblo
was operated steadily on zinc-lead
ores from various counties In Colo
RADIO, and also from Arizona, Idaho.
Montana. Nevada. and Utah The
Western Chemical Company's sui
phuric acid, magnetic separation, and
wet concentration plant, at Denver,
was operated steadily, as was the En-.
pire Zinc Company's magnetic separa.
don plant, at Canon City, both treat
ing chiefly Leadville lead-zinc ores.
The Sutton, Steele and Steele dry con-
centration and static electric separa-
tion plant was operated throughout
the year on many tests lots and later
on custom ore purchased from various
districts in TIE state.
Cripple Creek produced 60 per cent
Of the total gold yield Of the state,
with a yield of $1O,905.003, as COM
pared with $11,00s,362 in 1912. The
output for II months from Cripple
Creek seemed to indicate production
for IL months of $11,184, 900, but the
severe storm Of December 4th so Grip
pied transportation facilities that tho
December yield fell off heavily. There
was an increased yield Of gold bullion
from custom cyanidation plants at
Colorado Springs and from the cyan
idaticn mills in the district, the de-
creased yield being due to decreased
tonnage OF smelling ore. The Roose-
velt tunnel continued to lower the wa
ter level gradually. In the Vindica-
tor and Golden Cycle mines electric
pumps were installed. Lower levels
were opened in various properties.
The Golden Cycle and Portland cy-
anidation mills at Colorado Springs
wer operated steadily. The Portland,
STATIONS Independence, Ajax, and
several other cyanidation plants in
the district were operated continu-
ously. The Standard chlorinatiop and
cyanidation plant at Colorado City
was idle, but the Union cyanidation
plant, at Florence, was operated part
of the year on old tailings. The pub
lie report Of the Portland company for
1913 shows a total OF 1892 tons Of
an average assay value Of $2.95 per
ton was treated at the Portland COM
pany's Victor mill, with satisfactory
net earnings. The Stratton's 1nde-
.pendence report shows a recovery OF
7s.4S per cent on ore averaging $3.O76
per ton. the cost of working the mill
being $1.46 per ton.
