County
furnished 10,550,303 ounces, mainly from the siliceous ores of Tonopah.
Mineral County ranked second with an output of 522,987 ounces, mainly
from the Hawthorne and the Rawhide districts. Storey County followed
with 320,716 ounces from siliceous ores of the Comstock. Humboldt
County was fourth in 1910 with a production of 280,632 ounces, chiefly
from National. White Pine County produced 199,222 ounces, mainly from
copper ores, and Esmeralda County 198,703 ounces, largely from the
Goldfield ores. Of the total silver production in Nevada in 1910
siliceous ores produced 11,763,012 ounces, mainly from Tonopah, lead
ores 583,282 ounces, chiefly from the Hawthorne district, and copper
ores 107,365 ounces, mostly from the Ely district.
New Hampshire and Pennsylvania.—There
was a small production of gold and silver from the New Milan
copper-pyrite mine in New Hampshire in 1910, and the figures of output
have been combined with those of the recovery of precious metals from
copper-pyrite concentrates from ores of the Cornwall iron mine of
Lebanon County, Pa. Concentrates from the latter are saved by magnetic
separation, and briquetted, for sale to copper smelters, by the Grondal
process, the result being increased purity of the iron ores and a
marketable product of copper pyrite. The production in 1910 from both
States was $6,017 in gold and 526 fine ounces of silver.
New Mexico.—The
production of gold in New Mexico was $482,424 in 1910, against $239,491
in 1909, an increase of $242,933. Socorro County led in output of gold
with $311,114, followed by Grant with $65,932, and Lincoln with
$55,276. Siliceous ores, mainly from Socorro, Lincoln, and Grant
counties, produced over 88 per cent of the gold output; copper ores,
mainly from Grant County, furnished over 6 per cent, and placers
supplied $26,094, or 5.4 per cent of the total. The smelters in New
Mexico remained idle in 1910, the shipping ores going mainly to the El
Paso and the Copper Queen plants. The gold ores, however, are mainly
siliceous milling and cyaniding ores. The development of mines and
erection of gold mills in New Mexico in 1910 indicates further increase
in output in 1911.
The
silver production of New Mexico in 1910 was 843,987 fine ounces,
against 397,783 ounces in 1909, an increase of 446,204 ounces. Socorro
County produced 662,000 ounces in 1910, or 78.4 per cent of the total,
chiefly from siliceous ore from the Mogollon district, and the
Magdalena district of Grant County supplied 156,557 ounces, or 18.5 per
cent, chiefly from siliceous, copper, and lead ores.
Oregon.—The
gold production of Oregon in 1910 was $679,488, against $781,964 in
1909, a decrease of $102,476. Baker County again led in production of
gold, with an output of $401,002, followed by Josephine County with
$150,048. The total placer production was $170,925, of which Josephine
County produced $86,775 and Jackson County $37,926. Of the gold output
from quartz mines Baker County produced $389,726, in 1910, and
Josephine County $63,273. Six dredges in Oregon produced $34,010 in
1910, the greater part of which came from Jackson County. Southwestern
Oregon produced $209,324 in gold in 1910 (a decrease of $64,921), of
which the placer output was $130,103 (a decrease of $55,149).
Northeastern Oregon produced $470,164 in gold (a decrease of $37,555),
of which the placer output was $40,822 (an increase of $4,756).
