the Con-Imperial pit and protect historic houses and landmarks. Late. in
1978, the company obtained the necessary State permits to operate a gold
processing plant near Manhattan in Nye County. The plant will employ 60 people.
 Late in 1979, Anaconda announced its decision to begin construction on a
mining and milling complex to treat molybdenum ore in Nye County about 20
miles northwest of Tonapah. Development costs will approach $22 million,
and the project will employ nearly 400 people. Estimated life of the mine
and open pit operation is 20 years. 
 Resumption of large-scale tungsten mining near Imlay, in Humboldt County,
was announced by Utah International in 1979. The company submitted an application
to the State for permission to construct the $50 million facility. 
 Drilling exploration for metals and nonmetals continued at an alltime high
for both years. The principal metal ores involved were gold, silver, tungsten,
and molybdenum; barite, gypsum, and clay were the principal nonmetallics.
Several exploration 
companies are reevaluating and drilling in and along the Roberts Mountain
thrust fault. This mineralized zone in the fault system extends from the
southwest to the northwest in north-central Nevada. Freeport Minerals Co.
announced in April 1978, the discovery of a substantial gold deposit in Jerritt
and Marlboro Canyons, within the Humboldt National Forest in Elko County.
This deposit is significant; the company staked claims covering 42 square
miles. A company called Freeport Gold Co., a subsidiary of Freeport Minerals
and FMC, was formed to continue evaluation of the property and to be the
operator. In late 1979, environmental baseline studies commenced for a draft
environmental impact statement on the mine. Under an option agreement, Freeport
was also exploring a block of claims of the Owyhee Syndicate, near Tuscarora.
Geochemical surveys and rotary drilling indicate that measurable gold values
are present over much of the area. 
 Amselco Minerals, Inc., a wholly owned U.S. subsidiary of Selection Trust
Ltd. of London, anounced a major gold discovery
