value in gold and silver, copper, lead
and zinc, according to preliminary es-
Inmates of V. c. Heikes, of the Uni
ted States Geological Survey OF this
total, which is about 5 per cent less
than in 1912, the value of copper forms
the largest part, or 81 per cent; that of
gold, 80 per cent; that of silver, rs per
cent; and the values of lead and zinc
each about 2 per cent.
The mine production of gold de
creased about 10 per cent, from $l3,-
456,180 in 1912 to $l2,072,Oo0 in 1918
The silicious ores cyanided were the
main source of gold, which, in the
form of bullion, was shipped chiefly
from Goldheld, Tonopah, Fairview,
Wonder, Virginia City, Manhattan,
Round Mountain, National and Seven
Troughs An increase estimated at Is
per cent in the Nye county produc-
ton OF gold, from $3l23,935 in 1912 to
$3,o02,753 in 1918, is due TO the large
tonnage of silver ore treated at To
nopah and OF gold ores at Manhattan
The latter, according to the closest es-
Inmates, produced S577,900 in gold
from quartz mines and placers, as
against S497 $50 in 1912 AT the Cold
field Consolidated mines at Goldheld
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,
Vcrnal, Belmont, Great Bend and Dia
mondfield Black Butte mines. Aside
from Goldheld Consolidated, the most
important production came from the
Jumbo Extension mine from which
2,060 tons per month were concen-
trated at the Bonnie Claire mill SO
mitcs south of Goldheld The last half
OF the year this mill was altered also
TO scyanide ore from the Florence
GeldEeld mine. and in October 50 tons
per day were being treated In
Churchill county important gold and
silver productions were made by the
Nevada Wonder and Nevada Hills
companies. In the Searchlight dis
trict OF Clark county much gold ore
was cyanided. especially at the Quar-
tette mine. but the plant burned in
August. Pi ioduction from National
and Seven Troughs was comparatively
small
Nevada in 1913 was the leading
State in silver production, which came
mainly from the silver ores at To
nopah The mine production in
creased to about Is. 100000 ounces, or
about 7 per cent Eleven OF the To-
nopah mines produced ll,9Z5.ool
ounces OF silver, which was extracted
from the ore largely by the cyanide
process. In 1912 the district yielded
l0,l44.o87 ounces OF silver. The Bel
mont mine followed by the Tonopah
Mining and West End Consolidated
were the largest producers. On the
CoInstock lode in Storey county the
silver ores yielded about 81 ,24S,O0O in
gold and silver. This is slightly less
than the output valued at 81 ,3S2,OSe IN
1912. The newly opened mines OF
Rochester in Humboldt county in
creased production in 1913. These are
essentially silver ores. In September
100 tons per day were being shipped
by way of Oreana, new narrow
guage road to this point being com
plcied. At Virginia City the Mexi-
can mill turned on much bullion, not
only from the Mexican mine, but also
from the Monte Cristo mine which
was leased. The Buffers plant OF the
Chollar Leasing Co was active on
Chollar and Potosi ore and the new
Comstock Phoenix mill in Six Mile |
Canyon was operated.
An increase estimate at per centin
the mine production of copper from
86,477 ,494 pounds in 1872 to about
88,36SSo0 pounds in 1918, is due 10
slight increase in the output of the Ne
vada Consolidated and Giroux mines
rom copper ''porphyries" at Ely and
in 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 transporta-
tion reached the district.
The lead mine ouput decreased from
lo, 500, 100 pounds in 1912 to l5,3OO,0O0
pounds in 1918, or about Il per cent
This decrease is largely due to the
falling off of shipments from the Bull
lionyille failing dump near Phoebe
The Yellow Pine district in Clark
county had its usual output of about
