increase estimated at is per cent in the
Nye County production of gold, from
So. 1913. 935 in 1912 to So. 602. 1853 in 1918,
is due to the large tonnage of silver ore
treated at Touopah and Of gold ores al
Manhattan. The latter, according to
the closest estimates. produced $577, 900
in gold from quartz mines aud p%lacers,
as against 1897 $3.50 in 1912. At the Gold
field Cons olidated mines at Goldfield
nearly the same tonnage of gold ore was
treated at the mill as in 1912, but the
average grade was lower according to
printed monthly reports. Ore ship
ments in the district were made from
the O. 0. D.. Nevada Eagle, Vernal,
Belmont, Great Bend and Diamondfelu
Black Butte mines. Aside from Gold
field Consolidated, the most important
production came from the Jumbo Elk.
tension mine from which 1000 tons per
month were concentrated at the Bonnie
Glare mill, 38 miles south of Goldfeld.
The last half of the year this mill was
altered also to cyanide ore from the
Florence Goldfeld mine, and In October
90 tons Pc day were being treated. In
Churchill County important gold and
silver productions were made by the
Nevada Wonder and Nevada Hills Com
panies. In the ~Searchlight district OF
Clark County much gold ore was cy.
anided. especially at the Q~uartetr,
mine. but the plant burned in August.
Production from National and Seven
Troughs was comparatively small.
Nevada in 1918 was the leading State
N silver production, which came mainly
from the silver ores at Tonopah. The
mine production increased to about 49,
Boo, 900 ounces, or about z per cent.
Eleven of the Tonopah mines produced
IL. 923, Col ounces of silver, which was
extracted from the ore largely by the
cyanide process. In 1919 the district
yielded 10. 144. 987 ounces of silver. The
Belmont mine followed by the Tonopah
Mining aud West End Consolidated
were the largest producers. On the
Comstock lode in Storey County the
silver ores yielded about l,248, 900 in
in gold and silver. This is slightly less
than the output valued at 81 1859 ,089 in
1912. The newly opened mines of
Rochester in Humboldt County in.
creased production in 1918. These are
essentially silver ores. In September,
100 tons per day were being shipped by
way of Oreana. a new narrow gauge
road to this point being completed. At
Virginia City the Mexican mill turned
out much bullion, not only from the
Mexican mine but also from the Monte
Cristo mine which was leased. The
Buffers plant of the Ohollar Leasing
Co. was active on Chollar and Potosi
ore and the new Comstock Phoenix
mill In Six Mile Canyon was operated.
An increase estimated at 2 per cent
in the mine production of copper. from
So. AT. 494 pounds in 1919 to about 49,
1858. $50 pounds in 1918, is due to q
Light increase in the output of the Ne
vada Consolidated and Giroux mines
from copper ''~porphyries" at Ely and
in a larger output of copper matte at
he Thompson smelter from Mason
valley. Nevada Douglas, and custom
ores. Shipments Of copper ore were
made from the Pyramid Lake region in
Washoe County since transportation
feached the district.
The lead mine output decreased from
10. soc, 100 pounds in 1912 to 10. 800 900
pounds in 1918. or about 81 per cent.
This decreaae is largely due to the fall
ing of Of shipments from the Bullion
vile failing dump near Phoebe. The
Yellow Pine district in Clark County
had Its usual output of about $500. 900
pounds. The lead mines in Eureka
