GOLD, ETC., IN CALIFORNIA, NEVADA, AND OREGON 129

NEVADA

 The value of the mine production of gold, silver, copper, lead, and zinc
in Nevada, in terms of recovered metals, decreased from $11,673,787 in 1931
to about $5,135,792 in 1932. Compared with the 1931 production there were
decreases in the output and value of all metals, substantial ones being recorded
in the output and value of copper, lead, and zinc. Silver decreased 46 percent
in both quantity and value compared with 1931.

 Gold.—The gold from mines in Nevada decreased from $2,941,473 in 1931-
to about $2,695,607 in 1932. The decline in gold production in 1932 recalls
the period from 1892 to 1895 when the output dropped below $2,000,000 a year,
reaching the lowest point in 1893 with a production of $985,700. Mine production
was revived in 1896 by the gold discoveries at Delamar, which again promises
to become an important gold-producing district, Gold contributed over 52
percent of the total gross value of metals produced in the State in 1932.
Five companies, each producing between 10,000 and 20,000 ounces, yielded
52 percent of the State total; these 5 companies combined with 6 other companies,
each producing between 1,000 and 10,000 ounces, yielded over 71 percent of
the total gold output of the State. Due to the decrease in mining activity
in all parts of Nevada, the yield of gold did not increase as it did in some
other gold-producing States. In the Robinson district, White Pine County,
where considerable gold has been recovered heretofore from the mining of
copper ores, a substantial decrease was recorded; but in the Goldfield district,
Esmeralda County, the output of gold exceeded that in 1931. The mines of
the Tonopah district produced about the same amount of gold as in 1931. The
leading gold-producing companies in Nevada in 1932 were the Elkoro Mines
Co. at Jarbidge; the Bradshaw, Inc., at Goldfield; the Nevada Consolidated
Copper Co. at Ely; and the Gold Hill Development Co. and the Nevada Porphyry
Gold Mines, Inc., both at Round Mountain.
 A record of the exact number of people prospecting in Nevada for placer
gold during 1932 is not available, but engineers of the Nevada State Bureau
of Mines estimate that 600 to 700 men were at work in placer areas. The gold
produced in regularly worked placer districts increased over that of the
previous year, but just how much was produced by small-scale mines was not
determined. The principal placer areas producing iii 1932, named in order
of production, were Round Mountain, Battle Mountain, Manhattan, Osceola,
and Lynn.
