THE MINERAL INDUSTRY OF NEVADA

val's Copper Canyon pit. 
 In 1979, Kennecott began engineering feasibility studies on recovering copper
from old tailings at McGill; the engineering work contract was awarded to
Pullman Torkelson Co. of Salt Lake City, Utah. 
 Gold.—Nevada led all States in gold production in 1977; it was
second
in 1978, and fell to third in 1979. The State produced nearly 26% of the
Nation's newly mined output in 1978 and 22% in 1979. The Carlin Mine, Eureka
County, continued to be the State's largest producer. Production for both
years was centered in Elko, Eureka, Lander, Lincoln, Nye, Storey, and White
Pine Counties. Placer gold recovery was insignificant. About 10 heap-leach
cyanidation plants operated in the State, producing precious metals. 
 Dramatic price increases over the past 2 years have spurred gold exploration
activity to an alltime high in terms of expenditures. 
In April 1978, Freeport Minerals Co. announced the discovery of a substantial
gold deposit in Jerritt Canyon, Elko County. Anomalous values have been located
over a 42-square-mile area. Pinson Mining Co., a syndicate of four Canadian
mining firms, announced the Pinson and Preble gold properties, Humboltit
County, will be in production in 1980, at a cost of $14 million. 
 Iron Ore.—Output in 1979 increased over that reported in 1977-78;
value for 1979 nearly doubled that for 1977. Direct shipping ore accounted
for 88% of total mine production. All 1979 shipping-grade ores were produced
by the Nevada Barth Corp. (Eureka County), and Cooney Bros. (Pershing County).
Standard Slag Co. concentrated 21,000 long tons of iron ore from its Stakes
iron property in Nye County. 
 Lead.—Production in 1978 showed a small decrease compared with
that
of 1977, while 1979 output fell significantly. This
