eleven months of 1914, with an es-

preliminary figures by Charles w.
Henderson of the United States geo.
logical survey, indicates a yield of
$19,S60,OO0 in gold, S,742,00O ounc-
es of silver. 75,550,O00 pounds of
lead, 6,677,000 pounds of copper
and 96,0OO,O00 pounds of zinc Tin

S97,773 pounds of lead, ~7,227,S26
pounds of copper and 119,346,429
pounds of zinc, with a total value of
s35,450,5S5, in 1913. This shows
an increase of $1,713,0OO in gold
and decreases of $4,000 ounces in
silver. 12,34S,000 pounds in lead,
$4,000 pounds in copper, and 49,
100000 pounds in inc. In addition
to the decrease in quantities of sill
yer and the base metals, the falling
off in average value for these metals
caused a decrease in value of $685.
900 for silver, $9921,0O0 for lead
and $3.50, 900 for inc.
The tonnage treated by the Globe,
Leadville, Pueblo and Salida smelt-
ers was approximately the same as
in 1913. Copper ore from Rico and
copper matte from Ouray were ship
ped to lants in Utah. Cyanide re-
cipitates and copper ore were ship
ed to Omaha. The copper mating
plant at Ouray was operated stead
lily during the year and a 2OO-ton
increase was made in it's capacity,
construction work being completed
by the end of the year 1914. The
tonnage treated at the United States
Zinc company's magnetic plant and
smelter at Pueblo was less than in
1913.
The gold output of Cripple Green
TELLER county, was $12,04S, 900, an
Increase of $1,143, 900. This is the
largest production for any one year
since 1908. Cripple Creek to the
end of 1914 has produced $259,OOO.-
600 in gold. The Roosevelt tunnel
continued to lower the water level
gradually, except in the indicator
and Golden Cycle mines, where cleo
trio pumps. installed in 1913, ara
used. In July, 1914, preparations
were completed for continuing the
tunnel to the Vindicator-Goldan
Cycle territory, and since then the
tunnel has been advanced at the
rate of six feet a day.
The Golden Cycle and Portland
cyanidatiOn mills at Colorado
Springs were operated steadily,
with a considerably increased out
put. Cyanide mills in the district
also made an increased yield. The
Union cyanidation mill at Florence
was idle. The tonnage of smelling
ore from Cripple Creek increased ap-
probably.
Lake county. chiefly from Lead
vile, but also from the Lackawanna
Gulch and st. Kelvin districts, pro-
duced $~1.554,0OO in gold. $500, 900
ounces of silver, 27,OOO,OOO pounds
of lead. 2,47O,OOOO pounds of lead,
2,470,0O0 pounds of copper and TO-
600, 900 pounds of zinc, with a total
value of $4,000. 900, against $1,O23,-
631 in gold, 3,4O0,31S ounces of sill
yer. 2~9,2S6,1S3 pounds of lead. L.
923,9S7 pounds of copper and 93,-
S42,S57 pounds of inz, with a total
value of $~9,919,433, in 1913. The
output of zinc carbonate was Ill ,0G0
tons. of PAT per cent zinc, against
1890 tons of 27.45 per cent zinc
in 1913. The zinc sulphide smelt-
ing ore and concentrating ore COM
bined increased from 97.704 IONS of
23 per cent zinc in 1913 to 1900
tons of 20 per cent zinc in 1914. The
zinc carbonate ore was treated at
smelters in Kansas, Oklahoma, Illi-
nois and Wisconsin,, and the zinc
sulphide was treated at the Empire
Zinc company's magnetic separation
plant at Canon City, at the Western
Chemical company's sulphuric acid
wet concentration and magnetic sep
aratiOn plant at Denver, at the Unit
ed States Zinc company's magnetic
plant and smelter at Pueblo, at the
zinc oxide plant at Coffeyville, Kan,
and at other zinc smelters. A So
ton zinc oxide plant was built at
Leadville for the treatment of zinc
carbonate ores of 16 per cent or less,
but was operated for only a short
period. The Leadville district mill
was remodeled and the minerals sep
aration flotation equipment added,
and after considerable experimental
work was operated on zinc-lead sui
phide ores from Leadville and Eagle
county. Some zinc sulphide ore was
also treated at the Sutton, Steele &
Steel company's dry separation plant
at Denver during the year, but in
December this plant was closed. The
