was due to Bunker Hill Co.'s closure in 1978 of the Pan American Mine in
Lincoln Coun ty. Lesser quantities of lead came from small operations in
Churchill, Elko, Eureka, and Lander Counties In 1979 the promi nent producer
was Gold Creek Silver Mines in Elko County. 
 Mercury.—Production fell slightly in 1978, compared with that
of 1977,
but rose in 1979 to surpass the 1977 level in both quantity and value. Nevada
remained the leading mercury mining State for both years, producing nearly
99% of the Nation's metal. The McDermitt Mine, Humboldt County, was the United
States largest single producer; other production in Nevada was as a byproduct
from the Carlin Gold Mining Co. in Eureka County. 
 Molybdenum.—All Nevada molybdenum production came as a byproduct
from
Kennecott Copper Corp.'s McGill copper concentrator. Production fell dramatically
in 1978, 
compared with that of 1977; only stocks were shipped in 1979 Because of closure
of Kennecott s mining facilities in White Pine County, molybdenum production
in 1979 was only a third of that for 1978. In 1979, the Anaconda Co. announced
plans for a mining and milling complex (Hall property) for molybdenum ore
in Nye County, about 20 miles northwest of Tonopah. 
 Silver.—Silver production rose slightly in 1978, compared with
that
of 1977, but in 
1979 dropped below the 1977 level. Value rose significantly in 1979 because
of rapid price increases in the last half of the year. There were 14 producers
in 1978, and 11 in 1979. West Coast Oil and Gas Corp.'s Gooseberry Mine,
Storey County, was the leading producer both years. Notable production also
came from Duval's Copper Canyon and Bunker Hill's Pan American Mines (1978).
 Events in 1979 should, in the future, cause Nevada to again be prominent
