SWEETWATER ROADLESS AREA, CALIFORNIA AND NEVADA.

Mineral surveys of the Sweetwater Roadless Area, located on the east side of the central Sierra Nevada in California and Nevada, were conducted. On the basis of these investigations, the roadless area has probable and substantiated resource potential for gold, silver, copper, iron, molybdenum, and tungsten. If undiscovered resources are present, they are likely to be of the epithermal-vein and disseminated precious-metal (silver, gold), disseminated molybdenum porphyry, or contact-metasomatic (iron, copper, molybdenum, tungsten, gold) types. The geologic terrane precludes the occurrence of fossil fuel resources.
