$17,752,627;
Maryland, from 1867 to 1914, with $71,339; North Carolina, from 1799 to
1914, with $23,416,357; South Carolina, from 1829 to 1914, with
$5,176,237; Tennessee, from 1831 to 1914, with $230,217; and Virginia,
from 1828 to 1914, with $3,293,407. The output of all of these States,
except North Carolina, has been relatively small in recent years, but
the region is classic ground and the placers and free-milling quartz
lodes produced the first gold for domestic coinage, which caused the
establishment of a United States mint at Dahlonega, Ga., and a United
States assay office at Charlotte, N. C. The region also furnished the
first trained gold miners and stamp-mill operators to develop the gold
fields of Colorado and California.
Gold.—The
combined mine production of gold in Alabama, Georgia, North Carolina,
South Carolina, Tennessee, and Virginia in 1914 was $173,364, against
$165,733 in 1913. North Carolina again ranked first, with $131,141,
followed by Georgia with $16,270, Alabama with $11,970, and South
Carolina with $7,360. The output is almost wholly from gold-quartz ores
and from placers. The output from Tennessee was $6,194, entirely from
copper ores of the Ducktown district.
Silver.—The
output of silver from the southern Appalachian States was 100,727
ounces in 1914, against 111,205 ounces in 1913. Tennessee supplied the
bulk of this as usual (97,402 ounces in 1914) from the Ducktown copper
mines.
TEXAS.
Gold.—The
total output of gold from Texas mines from 1885 to the end of 1914 is
given by Charles W. Henderson as $46,618.' The yield has been merely
nominal and a by-product, being only $234 in 1914 and $340 in 1913.
Silver.—The
total production of silver in Texas from 1885 to 1914, inclusive, has
been 11,742,409 fine ounces, valued at $7,924,494, according to
Henderson. The mine production of silver in 1914 was 530,817 ounces,
against 427,553 ounces in 1913. The bulk of the Texas production of
silver has been from the oxidized milling ores of the Presidio mine,
Shafter district, Presidio County, whose ores were first treated by
amalgamation and more recently by cyanidation. Operations continued
throughout 1914.
UTAH.
Gold.—The
total output of gold in Utah from 1864 to 1914, inclusive, is given by
V. C. Heikes, of the United States Geological Survey, as $82,580,121.2 There has been a continued decrease in recent years due mainly to declining output and final exhaustion of the Mercur mines of Tooele County.
The
mine production of gold in Utah in 1914 was valued at $3,265,347,
against $3,565,229 in 1913. Salt Lake County again had the largest
output, $2,159,500 in 1914, against $1,777,214 in 1913. The Bingham
district alone, with its enormous output of copper and other ores,
produced $2,151,520 in gold in 1914. The Tintic district,
