BIG YEAR FOR NEVADA MINES
From the U. s Geological Survey

The value of the gold. silver, cop
per. lead and zinc from the mines of
Nevada in 1916 was approximately
s52,475, 900, according to the prelimi-
nary figures of Victor c. Heikes. of
the United States Geological Survey.
Department of the Interior. This
total represents an increase of near
ly $4,000, 900. or about So per cent.
above the corresponding figure of
1915, which was $34, ,551 ,436. There
were large increases, and record pro-
ductions, made in copper. lead, and
zinc. but there was slight decrease
in silver and large decrease in gold.
The mine output of gold was val
ued at approximately 100000 in
1916. a decrease of 22 per cent from
the output of 1915, which was $11,-
404. 300. The gold output from cop
per ore was increased. but that from
amalgamation and cyanide mills was
less in many of the camps. The
Pittsburg- rg-Silyerpeak mill. in Esme-
ralda County, was dismantled, and
the Buckhorn, in Eureka County,
was closed down. Both of these were
important producers in past years.
The Goldfield Consolidated. which is
the most important gold producer of
the State, was treating approximate
ly 10000 tons of ore per month. The
output, however. was considerably
less than in former years. A large
fotation plant was being added at
this property. The Jumbo Exten-
sion doubled its ore output. shipping
from 1000 to 5000 tons per month.
Shipments were also made from the
Atlanta. and fiotation concentrates
by the Nevada Metal Extraction
Company. One of the most import
ant additions to the gold and silver
production was from the operations
of cyanide mill at the Elko Prince
property at Midas. Operations at
Seven Troughs. National. and Round
Mountain were somewhat less than
in the preceding year. From Search
light. in Clark County. ore and pre-
cipitates were shipped, and at Raw
hide. in Mineral County. the Nevada
New Mines acquired the Black Eagle
property and operated two mills. At
Aurora there was also an increase in
gold output.
The mine production of silver was
about l3. $50. 900 ounces. which repre-
sents a decrease from IA, Ass, $40
ounces in 1915. The value of this
output, however, on account of the
higher price of silver. increas ed from
1881, ,139 to about So. .000. 900 or %
per cent. The silver output comes
chiefly from the Tonopah district.
where there was a marked decrease.
In 1915 the district produced 516.s37
tons of ore. $2,228,9 1888 in gold, and
10,171 ,374 ounces of silver. In 1916
the district produced approximately
448,0OO tons of ore 81 ,941 900 in gold.
and 1884 900 ounces of silver. The
largest producers were the Tono-
pah Belmont, Tonopah Extension.
Tonopah Mining. Jim Butler. West
End, Montana Tonopah. Halifax To-
nopah, and Tonopah Midway. The
Rescue Eula and Cash Boy were new
producers. AT the Tonopah Exten-
sion property 10 stamps were added
to the mill equipment. In the Ro-
chester district. of Humboldt County,
there was an increase in both gold
and silver production from mill opera
tions at the Nevada Packard and the
Rochester Mines Company, each
treating 100 tons day. tits planned
to double the capacity of the plant
of the Rochester Mines Company.
In the Comstock district, of Storey
County, there was an increase of ap-
proximately go per cent in the value
of the gold and silver output. The
production in 1915 was valued at $685.

the most important producer. ship
