NEVADA MINERAL PRODUCTION
For Year 1912 Shows Amaz-
ing Increase And Proves Our
Mineral Resources.

The total metal yield from ores
mined in Nevada during 1912. ac-
cording to preliminary figures by Y.
c. Heikes of the United States Geo.
logical Survey, was valued al nearly
s36,500,000, which was little over
per cent greater than the value for
1911
The gold output forms the largest
part, or 81 1a per cent, of the total
value; copper nearly S4k percent,
silver slightly in excess of 23 per
cent and lead and zinc each over 2
per cent. The Goldfield mines pro-
dueed more ore but less gold in 1912
and with this decreased output from
the National and Seven Troughs dis
triets was the principal cause of q
decrease in total gold production OF
about IS per cent from the yield of
| S18,193,397 in 1911. The mill at
the National mine was burned early
in September, and work was delayed
at Seven Troughs by damage from
cloudburst in July The Goldfeld
Consolidated, according to report
published was producing 10000 tons
of ore month, but the recovery
from ore treated decreased from
| s25.09 q ton in January to S13.13
In September The Manhattan and
Round Mountain districts and mines
IN the Fairview district increased
their gold yield in 1912. The Au
rora and Rexal districts and the
new district of Rochester, in Hum
boldt county, are expected to add to
the future gold output. The Nevada
gold output for 1912 is estimated at
about $19,500,00O.
There has been a steady increase
in the annual silver output of Ne
Yada since 1901, when production
began at the Tonopah mines. In
1912 the producers of Tonopah in
creased the yield of ore from about
5000 tons to nearly $4,000 tons
weekly but the average silver con-
tent per ton decreased. The new
Tonopah-Belmont mill at the mine
began crushing ore in July, and
new 150-ton cyanide plant was erect
ed for the West End mine and oper-
ated the last half of the year. A
new 10-stamp mill at the Mcnamara
mine had its initial run in January.
The estimated per cent increase
in the silver output of Nevada, from
13,1S4,e01 ounces in 1911 to about
13,S40,000 ounces in 1912 was due
to lead ore shipments from Phoebe,
in Lincoln county. There was much
activity in the Comstock district of
Storey county. The Yellow Jacket
and Mexican mills were operated
the entire year, and a new cyanide
plant was completed for the Ophir
mine and operated in October.
An increase estimated at II per
cent in the production of copper
from 67,377,51S pounds in 1911 to
100000 pounds in 1912 is due to
the new smelter which started oper-
ations early in 1912 at Thompson
on copper ores produced chiefly from
the Mason valley and Nevada Doug
lass properties in the Yerington dis
trict High-grade copper matte was
shipped from this plant to Garfield,
Utah, for conversion. II is reported
that conyerters for the production of
blister copper will be built in 1913
at Thompson. The Nevada Consoli-
dated mines at Ely produced daily
from 10000 to $4,000 tons of low
grade copper ore, which was concen-
trated and then sheltered at the
Steptoe smelter at MeGill. One unit
of the Nevada Consolidated coneen-
traitor was devoted to the daily treat
ment of about 1000 tons of Giroux
copper ores. The labor strike of 26
days eurtailed the production to
some extent at the three mines.
Mines in the Phoebe district of
Lincoln county and the Yellow Pine
district of Clark county furnished
largest part of the lead production,
which is estimated to have increased
from 3,263,657 pounds in 1911 to
nearly 100000 pounds in 1912.
The adjustment of litigation at Pi-
oche resulted in increased ore pro-
duction in that camp. along with the
completion of railroad spur to the
Bullionville failing dump, which
furnished from IL to 15 cars daily.
About 800 tons of iron manganese
ore, containing small quantities of
lead and silver, was shipped daily
from the Prince mines, and 100 tons
