Geological Survey Issues a State
ment Showing 20 Per Cent
Less Production in 1914

compared with 1913 is shown in a
statement just issued by the U. 5.
Geological Survey. and is credited to
the influence of the European war
in lowering the price of the baser
metals. especially copper The ealue
Of the metal output Of Nevada in
1913 was s37 .097 .000 and the estimate
for 1914, by V. G. Hekes Of the Geo
logical Survey. is $2S. 800. 900. Mr..
Heikes states that there was a marked
decrease in copper production in
Nevada. especially during the last
third Of the year, considerable fall
ing off in lead and zinc and smaller
decreases in gold and silver.
The output of gold represented
about 40 per cent of he total value.
In 1914 there was decrease of a per
cent from $11. .795. .130 to about SILL
800. 900. owing partly to the lessened
output of copper ore and partly TO q
decrease in production of siliceou
ores, although many gold camps in
creased their production. The Gold
field district was by far the largest
gold producer in the State, as in for
mer years. The Goldfield Consoli-
dated Company treated over 1885,
600 tons of ore. but the yield de-
clined by over a million dollars. This
was Offset in part by better produc-
ton from other mines near by, es-
pecially that of the Jumbo Extension
Co.. which was milling and shipping
from 1900 to 5000 tons a month. the
ore being treated at Bonnie Clare
the first half of the year and later in
a section of the Goldfield Consoli-
dated plant. The Goldfield Florence
and Diamondfield were also active
producers. At the close of the year
promising strikes were made in the
camp. At Tonopah the gold output
increased from $2,613,843 in 1918 to
70. $50. 900 in 1914. In the Fairview
and Wonder districts. Churchill
County. there was slight increase
in gold, principally at the Nevada
Hills and Nevada Wonder mines. AT
Round Mountain a slight increase
was recorded, but at both National
and Seven Troughs marked increases
were made. In Mineral County the
Aurora Consolidated property was
acquired by the Goldfield Consoli-
dated Co., the new mill was complet-
ed and a considerable production was
reported. At Manhattan production
decreased about 40 per cent. -Four
mills were active for part of the
year. The Big Pine, Commercial
Mines, Manhattan Consolidated and
White Caps were large producers.
A new 2OO-ton mill for the Big Pine
was completed in December. At
Buckhorn. in Eureka County, 300
ton cyanide plant was active. Mills
were active at Rawhide and Jarbidge.
and new 10-stamp plants were
erected at Bullfrog and Basalt. At
Blair the Pittsburg Silver Peak mill
was in continuous operation, produc-
ing gold bullion, principally by
amalgamation.
The silver output decreased from
16. 500. .083 ounces in 1918 to about
Is, 200, 900 ounces in 1914 or only
about 5 per cent, although the price
per ounce was much reduced. The
value decreased from $9,718.410 to
about $8,313,0O0 The Tonopah dis
trict produced about 11.757. .00O
ounces from $1,000 tons of ore,
against 1854 437 ounces in 1918.
The largest output came from the
Tonopah Belmont, Tonopah Mining,
Tonopah Extension, West End and
Jim Butler mines. The rest of the
silver came largely from the Nevada
Hills and Nevada Wonder mines in
Churchill County, and from the Com
stock district, Storey County. The
output from the Comstock. however,
was considerably decreased. Much
silver ore was shipped from the Ro-
chester district. which produced 7O1..
407 ounces in 1918. The greater
part of the Nevada silver output
continues to come from siliceous ores
cyanided. At Virginia City the work
of unwatering the mines at the
2500-foot level was accomplished
Tube mill and classifiers were added
to the concentration plant of the
