This report presents the results of a mineral survey of the South Providence Mountains Wilderness Study Area (CDCA-262), California Desert Conservation Area, San Bernardino County, California. Geologic, geochemical, and geophysical evidence, together with a review of historical and recent mining and prospecting activities, suggests that much of the South Providence Mountains Wilderness Study Area has a wide range of potential for the occurrence of several types of undiscovered mineral resources. Eight mines and prospects in the study area have potential for gold, silver, lead, or copper resources. A high potential for epithermal volcanogenic gold resources is indicated for one small area of altered metavolcanic, plutonic, and hypabyssal rocks, and a moderate potential for epithermal gold resources is indicated for three other small areas. A low potential for placer gold resources is indicated for all alluvium in the area with particularly strong support for two small areas. Radioactive-mineral resources are possible in one area of granite, which is ascribed a low resource potential. A low potential for hydrocarbon resources is indicated for basinal sediments in a small part of the study area. Mines in and immediately adjacent to the study area contain an estimated 200,000 tons of indicated and inferred marginal gold reserves and an additional 11,000 tons of marginally economic gold-bearing dump reserves. Thirteen mines have potential for additional resources. 30 refs., 5 figs., 5 tabs. (ACR)
