The Conterminous United States Mineral Assessment Project; background information to accompany folio of geologic, geochemical, geophysical, and mineral resources maps of the Reno 1 by 2 degree Quadrangle, Nevada and California
The Reno 1 ? by 2 ? quadrangle in west-central Nevada was studied by an interdisciplinary research team to appraise its mineral resources. The assessment is based on geological, geochemical, and geophysical field and laboratory investigations, the results of which are published as a folio of maps, reports, figures, and tables, with accompanying discussions.

The Conterminous United States Mineral Appraisal Program; background information to accompany folio of geologic, geochemical, geophysical, and mineral resources maps of the Tonopah 1 by 2 degree Quadrangle, Nevada
The Tonopah 1 ? by 2 ? quadrangle in south-central Nevada was studied by an interdisciplinary research team to appraise its mineral resources. The appraisal is based on geological, geochemical, and geophysical field and laboratory investigations, the results of which are published as a folio of maps, figures, and tables, with accompanying discussions.

Mineral Resources of the Morey and Fandango Wilderness Study Areas, Nye County, Nevada
The Morey (NV-060-191) and Fandango (NV-060-190) Wilderness Study Areas are located in the northern Hot Creek Range about 25 mi north of Warm Springs, Nev. At the request of the Bureau of Land Management, 46,300 acres of the Morey and Fandango Wilderness Study Areas were studied. In this report, the area studied is referred to as 'the wilderness study area', or simply 'the study area'. Geologic, g

EAST PART OF THE RAYMOND PEAK ROADLESS AREA, CALIFORNIA.
The east part of the Raymond Peak Roadless Area, Alpine County, California encompasses about 58 sq mi along the crest and eastern slope of the Sierra Nevada. Based on a mineral survey there are demonstrated silver-gold resources at five properties within a large area of probable silver-gold potential in the east part of the area. A small area with probable mineral-resource potential for skarn-type

LINCOLN CREEK ROADLESS AREA, NEVADA.
On the basis of a mineral survey, the Lincoln Creek Roadless Area, Nevada was determined to have little likelihood for the occurrence of mineral resources. Geologic terrane favorable for the occurrence of contact-metasomatic tungsten deposits exists, but no evidence for this type of mineralization was identified. The geologic setting precludes the occurrence of fossil fuels and no other energy res

FREEL AND DARDANELLES ROADLESS AREAS, CALIFORNIA.
As a result of a mineral survey of the Freel and Dardanelles Roadless Areas, California several areas having demonstrated resources were identified: tungsten at the Alpine mine in the Dardanelles Roadless Area; silver and copper at the Mountain Top mine in the Freel Roadless Area; and, zinc, silver, and copper at the Alhambra prospect just outside of the Dardanelles Roadless Area. An area along th
