the mine output of gold, silver, cop
per, lead, and zinc in New Mexico in
1912, according to Charles w. Hender.
son, of the United States Geological
Survey at Washington, was $S,527, 955,
as against $2,7O4,s43 in 1911, an in
crease of $5,S2S,112.
The production of gold showed an
increase of $21,63S; silver $227,165;
copper $5,1O797s; lead, $113,751; and
zinc, $352,579.
Socorro county produced, chiefly
from the siliceous ore mines of Mogol-
Ion, $525,629 in gold, or 81 per cent of
the total state yield. There were in
creased yields of gold in Grant, Luna,
Otero, and Santa Fe counties, chiefly
from siliceous, copper, and lead ores.
The output of placer gold was $780,
926, against $1S,714 in 1911.
OF the silver yield Socorro county
produced, chiefly from the Mogollon
district, 1,126,429 fine ounces, or 70
per cent of the state total. Grant
county furnished 356,$57 ounces, chief
ly from siliceous, copper, and lead
ores; these two counties combined
produced over SO per cent of the total
silver yield.
Of the lead output, Grant county
produced 2,3O97 1872 pounds, chiefly
from the Central district, the Magda-
lena district, Socorro county, yielded
2,192,792 pounds; Luna county yielded
S27,556 pounds, chiefly from the vic
torio district; and the Gallinas dis
trict, Lincoln county, yielded 103,911
pounds. The increase for the state
for 1912 was 2,527796 pounds. Con-
centrates contained 1,9S4,435 pounds
of lead, and crude ore sent to smell
tiers 3,5O9,5S3 pounds
The tonnage of zinc sulphide con-
centrates from Kelly, Socorro county,
decreased somewhat, but the tonnage
of zinc carbonate ore increased, with
resultant small increase in zinc
yield for this county, from which
comes the greater part of the zinc out
put of New Mexico In addition to the
magnetic separation and wet-concen-
tration mill of the Tri-Bullion Co., the
new concentration mill of the Ozark
Co. with flotation equipment also),
was placed in operation in 1913, and
the output for 1913 may show a con-
siderable increase. In January, 1912,
the zinc deposits at Hanover, Grant
county, were reopened after being idle
a year, and a large tonnage of zinc con-
centrates was shipped from Pinos Al
tos. In Luna county considerable
tonnage of zinc carbonate was shipped
from the Cooks district, and several
shipments of zinc carbonate were
made from the Tres Hermanas and
Victoria districts.
The number of productive mines in
New Mexico in 1912 was las, of which
twenty-six were placers, against 105
in 1911, of which twenty were placers.
The average total recoverable value
per ton of ore produced decreased
from $11.54 in 1911 to 1929 in 1912,
adding to the large tonnage of low
grade copper ore handled by the Chino
tons Of ore from New Mexico was sold
ore treated in 1912, an increase over
1911 of 1,119,5S7 tons. OF this total 106,-
1913 tons went to a amalgamating and
cyaniding mills, 1,142,002 tons went
to mills for concentrating only, and
104,0S6 tons went crude to smelters.
OF the $42O,447 in gold and S42,O1S
ounces of silver in bullion produced
in New Mexico In 1912, the cyanide
process yielded $SSS,69S in gold and
S41, 575 ounces of silver, the re-
mainder being recovered by amalga-
nation.
The copper output of the state was
chiefly from Grant county, which pro-
duced 32,952.133 pounds. or 81 per
cent Of the total yield.
The increase in the copper output
came chiefly from the operations of
the Chino Copper Co.. which is mining
a great low-grade copper deposit at
Santa Rita by steam shovels. This
ore is concentrated at Hurley, where
a 5,000-ton plant has been erected in
five section, two sections being in OPP
Grafton at the beginning of the year
1912 and the other three being sue
cessively placed in operation during
the year, the last being completed in |
December. The annual report OF this
company shows that no more than
four section of the plant were oper-
ated continuously for any part of the
year 1912, but 1t is planned to operate
all five sections. The total gross pro-
