County
output of silver, the Bingham district produced about 80 per cent. The
Tintic district, in Juab and Utah counties, yielded 6,681,644 ounces
(mainly from lead ores); and the Park City region, in Summit and
Wasatch counties, produced 2,572,586 ounces, mainly from lead and
lead-zinc ores. Altogether the lead ores of Utah yielded 6,672,725
ounces of silver in 1918, the copper ores 1,445,559 ounces, the
lead-zinc ores 1,243,638 ounces, and the dry or siliceous ores
3,987,068 ounces. The crude ore smelted in 1918 contained 10,612,588
ounces and concentrates contained 2,316,766 ounces.
WASHINGTON.
The total production of gold in Washington from earliest mining to the end of 1918 is given by C. N. Gerry, of the United States Geological Survey, as $27,753,350, and the total production of silver as 7,363,533 fine ounces.1
Gold.—-The
mine production of gold in Washington in 1918 was $304,658, against
$492,324 in 1917. Of the production in 1918 more than 92 per cent was
derived from ores shipped directly to smelters, less than 4 per cent
came from ores treated by amalgamation or cyanidation, and less than 1
per cent came from placers. Siliceous ores supplied about 96 per cent
of all gold recovered and copper ores about 3 per cent. Ferry County
alone produced $276,066 in 1918, against $332,071 in 1917. Nearly all
the yield from Ferry County was, as usual, from the Republic district.
Silver.—The
mine production of silver in Washington increased from 282,320 ounces
in 1917, to 310,093 ounces in 1918, of which Ferry County produced
101,376 ounces, mainly from siliceous ores, and Stevens County 168,669
ounces, mainly from copper ores.
WYOMING.
The
total production of gold in Wyoming from 1867 to the end of 1918 is
given by Charles W. Henderson as $1,235,975, and the output of silver
for the same period as 69,540 ounces.2
The
mine production of gold in Wyoming in 1918 was $871, against $3,762 in
1917, and that of silver 965 ounces in 1918, against 3,415 ounces in
1917. The Hartville district, in Platte County, produced most of the
gold mainly from copper ores shipped to smelters. Copper ores shipped
from mines in Albany, Fremont, and Carbon counties contained nearly all
the remainder of the gold and silver reported in 1918.
PHILIPPINE ISLANDS.
The
output of gold in the Philippine Islands from 1907 to 1918, inclusive,
has been $9,049,522. The mine production of gold for 1918 was
$1,290,000, against $1,408,161 in 1917, $1,514,200 in 1916, $1,320,900
in 1915, $1,371,514 in 1914, $868,362 in 1913, and $570,212 in 1912.
The mine production of silver in the Philippine Islands in 1918 was
4,138 ounces and was recovered entirely from gold bullion refined.
