Matti 1982 <p>Geological, geochemical, and geophysical evidence, together with a 'review of historical mining and prospecting activities,&nbsp;suggests that most of the Whitewater Wilderness Study Area has low potential for all types of mineral and energy resources- including&nbsp;precious and base metals, building stone and aggregate, fossil fuels, radioactive-mineral resources, and geothermal&nbsp;resources. One small area in the southern part of the study area shows evidence of gold and silver mineralization, and this locality&nbsp;has a low to moderate potential for the discovery of low-grade gold and silver resources.</p> application/pdf 10.3133/mf1478A en U.S. Geological Survey Mineral resource potential map of the Whitewater Wilderness Study Area, Riverside and San Bernardino counties, California reports
