and zinc, according to preliminary es
Inmates of V. C. Heikes, of the United
States Geological Survey. OF this to
tai, which is about per cent less than
in 1912, the value of copper forms the
largest part, or 81 per cent; that of
gold 33 per cent; that of silver, 25
per cent; and the values of lead and
zinc each about 2 per cent.
The mine production of gold dc
creased about 10 per cent, from 3d.
456, $50 in 1912 to $12,072,00 in 1913.
The siliceous ores cyanided were the
main source of gold, which, in the
form of bullion was shipped chiefly
from Goldfeld, Tonopah, Fairview,
Wonder. Virginia City, Manhattan,
Round Mountain, National and Seven
Troughs. An increase estimated at Is
per cent in the Nye county production
of gold, from $3,123,935 in 1912 to
$3,602,753 in 1913, is due to the large
tonnage of silver ore treated at Tono-
pah and of gold ores at Manhattan.
The latter, according to the closest
estimates, produced $577, 900 in gold
from quartz mines and plaeers, as
against $497 $50 in 1912. At the Gold
field Consolidated mines at Goldfeld
nearly the same tonnage of gold ore
was treated at the mill as in 1912, but
the average grade was lower, accord
ing to printed monthly reports. Ore
shipments in the district were made
from the c. o. D., Nevada Eagle, Yer
nal, Belmont, Great Bend and Dia-
mondfield Consolidated the most i'm
portant production came from the
Jumbo Extension mine from which
1000 tons per month were concentrat
ed at the Bonnie Clare mill 3S miles
south of Goldfeld. The last half of
the year this mill was altered also to
cyanide ore from the Florence Gold
field mine, and in October so tons per
day were being treated. In Churchill
county important gold and silver pro
ductions were made by the Nevada
Wonder and Nevada Hills companies
In the Searchlight district of Clark
county much gold ore was eyanided,
especially at the Quartette mine, but
the plant burned in August Produce
tion from National and Seven Troughs
was comparatively small.
Nevada in 1913 was the leading
state in silver production. which came
The mine production increased to
about 15,300,000 ounces, or about 7
per cent Eleven of the Tonopah mines
produced 11,923,651 ounces of silver,
which was extracted from the ore
largely by the cyanide process. In
1912 the district yielded 10,144,9S7
ounces of silver. The Belmont mine
followed by the Tonopah Mining and
West End Consolidated were the larg-
est producers. On the Comstock lode
in Storey county the silver ores yield
ed about $1,24s,00O in gold and sill
yer. This is slightly less than the out
put valued at 1882, ,0S9 in 1912 The
newly opened mines Of Rochester in
Humboldt county increased produc-
tion in 1913. These are essentially
silver ores. In September, 100 tons
per day were being shipped by way of
Oreana, a new narrow guage road to
this point being completed. At Vir-
ginia City the Mexican mill turned
out much bullion, not only from the
Mexican mine but also from the
Monte Cristo mine which was leased.
I The Buffers plant of the Chollar Leas-
/ ing Co. was active on Chollar and
Pososi ore and the new Comstock
+ Phoenix mill in Six Mile canyon was
operated.
An increase estimated at per cent
in the mine production of copper, from
/ s6,477 ,494 pounds in 1912 to about
4 ss,36s, 800 pounds in 1913, is due to a
slight increase in the output of the
Nevada Consolidated and Giroux
mines from copper "porphyries at
4 Ely and in a larger output of copper
matte at the 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 trans
portation reached thhe district
The lead mine output decreased
from 1880, 100 pounds in 1912 to Is,
100000 pounds in 1913, or about 81
per cent. This decrease is largely
due to the falling off of shipments
from the Bullionville tailings dump
near Phoebe. The Yellow Pine district
in Clark county had its usual output
of about 6,500,000 pounds The lead
mines in Eureka county did not all re
sumo work, but the production of lead
was greater than for several years.
The output of recoverable speltel
from zine ores sold or treated increas
ed from 13,322,9ss pounds in 1912 tC
1887 900 pounds in 1913, or about Il
per cent Practically all of this out
put is from the Yellow Pine district
from carbonate ores. The Yellow
Pine property and the Potosi mine
were the largest producers of zinc.
Two copper plants at McGill and
Thompson were in continuous opera
tion. At Thompson seven milling
plants using principally the cyanide
process, treated 565,0O0 tons of slice
Gus ores. In the Manhattan camp
four mills oprated, treated approx
mately $4,000 tons of ore. All the
milling plants on the Comstock lode
and at Silver City were in operation
with steady tonnage maintained.
