GOLD AND SILVER.

TEXAS.
The
total output of gold from Texas mines from 1885 to the end of 1922 is
given by Charles W. Henderson as $43,607, and the output of silver for
the same period was 16,455,480 ounces.
Gold.—The small annual yield of gold has been mainly a by-product, and none has been reported since 1919.
Silver.—The
mine production of silver from Texas in 1922 was 644,980 fine ounces,
against 516,766 ounces (revised figures) in 1921. The greater part of
the silver continued to come from the Presidio mine, and the remainder
was derived from small shipments of copper ore and lead ore from
Hudspeth County.
UTAH.
Gold.—The total output of gold in Utah from 1864 to 1922, inclusive, is given by V. C. Heikes,5 of the United States Geological Survey, as $104,309,290.
The
mine production of gold increased from $1,769,905 in 1921 to $2,296,855
in 1922. The Bingham district, Salt Lake County, produced $1,187,355,
and the Tintic district, partly in Juab County and partly in Utah
County, produced $465,321. The placer gold in 1922 amounted to $2,130,
and the output recovered by cyanidation and amalgamation was about
$212,660. About 32.8 per cent of the Utah gold was derived from copper
ores mined mainly in Salt Lake and Juab counties; lead and lead-zinc
ores contained 32.6 per cent; and siliceous ores 34.5 per cent.
Silver.—The total output of silver in Utah from 1864 to 1922, inclusive, has been 433,756,159 fine ounces, according to Heikes.5
The
mine production of silver in Utah in 1922 was 17,271,100 ounces, an
increase of 5,019,102 ounces. The largest production was made in Juab
County, credited with 6,338,689 ounces, mainly from lead ores, against
5,031,030 ounces in 1921. Utah County had 2,217,547 ounces, mostly from
lead and siliceous ores, against 2,559,368 ounces in 1921. Of the Salt
Lake County output of 1,678,618 ounces, the Bingham district produced
1,381,299 ounces. The Tintic district, in Juab and Utah counties,
produced 8,533,954 ounces, mainly from lead and siliceous ores; and the
Park City region, in Summit and Wasatch counties, produced 5,245,194
ounces, all from lead and siliceous ores. Altogether in 1922 the lead
ores of Utah yielded 8,183,741 ounces of silver, the copper ores
473,284 ounces, the copper-lead ores 20,919 ounces, and the dry and
siliceous ores 8,110,733 ounces. The crude ore smelted in 1922
contained 12,940,173 ounces, and concentrates contained 2,737,644
ounces.
WASHINGTON.
The total production of gold in Washington from earliest mining to the end of 1922 is given by C. N. Gerry,6 of the United States Geological Survey, as $28,442,523, and the total production of silver as 8,170,091 fine ounces.
