METAL OUTPUT

BY U. 8. GEOLOGICAL SURVEY

was about s~23,960,00O, according to
preliminary figures compiled by Vic
tor C. Heikes, Of the United States
Geological Survey, Department of the
Interior. This represents an increase
of about $4,000 over the output
In 1919. A large decrease in the
quantity of gold was balanced by In
creases in other metals, but the out
put of copper. lead and zinc was still
far below that Of 1918.
The gold output Of Nevada de-
creased from s~4.541.502 in 1919 to
about s3,579.O00 in 1920. a decrease
OF more than twenty per cent. The
Goldfield Consolidated property, for
several years the largest gold pro-
Queer In Nevada, was operated by the
Goldfeld Development Company. and
a comparatively small production was
reported. The output Of gold from
the Tonopah district, however, in
creased from s771,s04 in 1919 to
about $1,063,000 in 1920, on account
| of the larger output of the accom-
panying silver. which was favored by
a high price. The Nevada Consoli-
dated Company, at Ely, operating
the largest copper mine of Nevada,
was also the largest producer Of gold
in the State. The Elkoro mine, at
J~arbidge, was the largest producer
Of gold from gold ores, and the Tono-
pah Belmont Company produced the
most gold from silver ores. other
mines that made an output of gold
valued at more than $15O,00O each
were the West End, Tonopah Extern
sion, Consolidated Virginia. and Ton
opah Mining Company. The Fair
view Round Mountain, Round Noun
tain, Rochester Mines, Elko Prince,
Montana Tonopah, and Florence
mines were also producers of gold,
though several of these failed to
reach the output of the previous year.
The mines Of the Comstock district
were active, especially in develop
ment work, though their output of
| gold was somewhat less than In 1919,
when they produced $355,640. In
the Rochester district, the Rochester
Mines Company was a large produc-
er of gold, and there was a fair in
crease over the output in 1919. Late
In the year the new dredge Of the
Gold Canyon Dredging Company be-
gan operations near Dayton on old
Comstock tailings.
The mine production Of silver in
| creased in quantity from 6,S63,580
ounces in 1919 to about ~7,786.000
| ounces in 1920 and in value from
s~7.6S7,210 to about s~8,480,O00. The
large mines of Tonopah district pro-
duced about 100000 ounces of sill
yer in 1920. against 3,56S,S75 ounces
in 1919 and 5.929,920 ounces in
1918. The largest producers of sill
yer were the Tonopah Belmont. West
End Tonopoh Extension, Tonopah
| Mining, and Montana Tonopah mines.
Large quantities of silver were also
produced by the Rochester mines
Company, Tonopah Divide, Spruce
Monarch. Black Metals. Consolidated
Virginia. Prince Consolidated. and
Nevada Packard. The Comstock dis
triet produced about $4,000 ounces
and several properties at Rochester
produced about $4,000 ounces. In
Churchill County a decided decrease
resulted from the idleness Of the Me-
vada Wonder mine.
The mine output of copper in
creased In quantity from 52,331,175
pounds In 1919 to about 55,790,000
pounds In 1920. but decreased in val
ne from $~s,733,599 to about $751;
000- The output was less than half
that in 1913. The Nevada Consoli-
dated. at Ely. in White Pine County.
was the largest producer and contri-
buted more than 1000. 900 pounds
of copper a month; but the Console
dated Coppermines, In the same coun-
ty. made no effort to produce copper
ore under the prevailing conditions.
The Mason Valley smelter, at Thomp-
son. in Lyon County. was idle during
the entire year, and many of the
mines of Lyon and Mineral Counties
therefore found 1t impossible to OPP
crate.
The mine output of lead increased
in quantity from ~15,s49.370 pounds
in 1919 to about ~1s.510.000 pounds
in 1920 and in value from $S13,517
to about s1.5s2.O00. The Prince
Consolidated mine, at Phoebe. and
the Yellow Pine mine, in Clark Coun-
ty. were the largest lead producers
