according to Charles G.. Yale of the
United States geological survey, was
s26,S12,4S9, compared with $780,
asa, 946 in 1912 and $25,174,677 in
, 1911. Except in zinc there was an
increase in the output of all these
metals, although the tonnage from
deep mines showed a decline and
there we're fewer mines reporting
production than in 1912.
The mine production of gold in
1913 was $20,4O6,95S = $693,4SO
more than in 1912, an increase Of
1852 per cent. The deep mines 81
the state produced $11,570,7S1, or
500 per cent of the total. The in
crease in gold from deep mines for
the year was %$502,966. or asa per
cent. The placer mines produced
$~S,S36,177 in gold, an increase OF
$190,514, or 2.2O per cent.
This output of gold in California
was the largest in 81 years, the yield
of 1883 having been $24,313,S73.
Only three times in 40 years has the
gold output exceeded $20,00O,0 900,
and If the year 1883 is excluded, the
gold output in 1913 was higher than
it has been since 1864. The gold Is
now derived from extensive opera
tions rather than from efforts of in
dividuals or numerous small enter.
prises. Some of the deeper quartz
mines are working as good ore Mt
vertical depths of 5000 to nearly
1000 feet as was found near the sur
face. The dredgers are now produc-
ing 91.56 per cent of the placer
gold from ground which was former
ly considered worthless for mining,
as being too poor in gold, having no
fall" or no drainage, and on which
water could not be used advantage
ously on any scale under the old
system of gravel mining. There are
now SO dredges in operation in Cal
ifornia, and since the beginning of
operations has reached a total Of
$63,5O5,485. From a production of
$2O6,3O in 1899 the annual output
from gold dredges reached in 1918
the sum of $S,09O,294, which Is
3.64 per cent of the total gold yield
of the state and 1.56 per cent of the
total output of placer gold. The n.y.
draulic mines produced $329,300, or
3.73 per cent of the total production
of gold in the state in 1918, the drift
mines produced ~$192,53S. or 2.1S
per cent; and the surface or sluic-
ing mines produced $224,045, or
2.53 per cent.
There were 40 deep mines re-
porting production in 1913, a de-
crease of 1872 compared with 1912.
A total of 2,495,958 tons of ore was
treated in 1913, a decrease of 49,
$50 tons. The s%iliceous ore treated
at gold and silver mills amounted to
1,A05,2 58 tons, yielding $S,469,245
in gold. or $4.44 a ton in bullion.
From this ore was derived 1852
tons of concentrates, which o n
tanned 50, ,656 in gold, or 5000
a ton. The average value in gold
and silver in the ore milled was
$5.57 a ton, of which 1852 was in
gold and S cents in silver. The $751;
1879 tons of ore sent to smelters
produced $S4O,03O in gold, or $1.58
a ton; and the treatment of 59,511
tons of old tailings yielded $197,650
in gold, or 1892 a ton. OF the total
recovery of gold in bullion from ore
treated at gold and silver mills, ST.
O25,279 was won by direct cyanida-
ton and $7,443,966 by amalgama-
ton. The total recovery of gold by
the cyanide process, including that
recovered by the treatment of old
tailings, was $~1,2S9,353.
The production Of silver at mines
in California in 1913 was 1,378,399
fine ounces, valued at $832,553, an
increase of 1928 fine ounces in
quantity and of $4,000 In value.
Much the larger portion, 1,158,517
fine ounces, valued at $699,745, was
derived from crude smelling ores.
Shasta county, as usual, was the
largest producer of silver, making
an output of 705.634 fine ounces
valued at $426,2O3, from the smelt-
ing of copper ores. 1926 fine ounc-
es from siliceous ores, 745 fine ounc-
es from placers, and 80 fine ounce
from lead ores = a total yield for
the county of TAI, 773 fine ounces,
valued at $44S,O31. The deep mines
of the state produced 1,343,O2O fine
ounces of silver, valued at $811,184,
and the placers produced $3.50 fine
ounces, valued at $21,369.
