$574,000.
The Goldfield district yielded $740,265 in gold in 1919, against
$1,212,572 in 1918. Nye County produced $1,537,980, of which Tonopah
yielded $771,804—a decrease in Tonopah of nearly $516,000. The counties
having a substantial increase in gold were Elko, Churchill, and Lyon.
Forty-seven per cent of the decrease in the outrAit of gold was due to
diminished yield from Goldfield and Tonopah.
Silver.—-There
was a decrease in the mine production of silver in Nevada in 1919, the
total being 6,863,580 fine ounces, against 10,000,599 ounces in 1918.
Nye County (almost wholly from the Tonopah district) again led in
output with 3,622,680 ounces, which was about 2,482,000 ounces less
than in 1918. Pershing County, with 706,700 ounces, Churchill County,
with 488,000 ounces, and Lincoln County, with 457,000 ounces, were the
other counties which had an output exceeding 400,000 ounces. Dry or
siliceous ores yielded all but 556,997 ounces of the output of silver,
and 88 per cent of this yield was recovered by cyanidation.
NEW MEXICO.
Gold.—The
mine production of gold in New Mexico in 1919 was $655,656, against
$682,791 in 1918. The Mogollon district, Socorro County, produced
$148,136; Grant County, $243,391; and Colfax and Lincoln counties,
$253,687.
Copper
ores, chiefly from Grant County, contained $233,489, and dry and
siliceous ores yielded $407,691. The output from other kinds of ore was
very small and the placer output was only $4,959.
Silver.—The
mine production of silver in New Mexico decreased from 1,394,365 fine
ounces in 1917 to 782,421 ounces in 1918 and to 837,418 ounces in 1919.
Socorro County produced 412,917 fine ounces, chiefly from siliceous
ores from the Mogollon district, the remainder from the mixed ores of
the Magdalena district. The output of silver from Grant County
decreased from 338,833 ounces in 1918 to 336,499 ounces in 1919, and
most of this yield came from the Lordsburg and Central districts. Dry
and siliceous gold and silver ores, chiefly from Grant and Socorro
counties, yielded 65 per cent of the total; copper ores, chiefly from
Grant County, yielded 28 per cent. The remainder of the production was
from lead and copper-lead ores, mainly from the Central, Cooks Peak,
Lake City, Victorio, and Magdalena districts.
OREGON.
Gold.—The
mine production of gold from Oregon decreased about 23 per cent, being
$977,845 in 1919 against $1,270,465 in 1918. The placer mines yielded
only $380,651, or $117,598 less in 1919 than in 1918. Sixty-six per
cent of the output from deep mines was from siliceous ores. The deep
mines of the State produced $597,194, a decrease of $175,022. The two
dredges in Baker County and one dredge in Grant County produced
$296,750, and a few drift mines, hydraulic, and surface placers in
Baker, Jackson, Douglas, Crook, Josephine, Wheeler, and Malheur
counties produced the remainder of the placer gold. Baker County, with
a yield of $837,163, was the only county that produced more than
$100,000 in gold.
