Mineral resources potential map of the Pusch Ridge Wilderness Area, Pima County, Arizona
A mineral resource assessment of the Pusch Ridge Wilderness Area was conducted by the U.S. Geological Survey and U.S. Bureau of Mines. The area was evaluated for its mineral potential by analysis of geochemical samples by the U.S. Geological Survey and by examination of mines, prospects, and mineralized areas by the U.S. Bureau of Mines. The Pusch Ridge Wilderness Area has a low potential for minerals and little surficial indication of potential for oil, gas, or geothermal energy. Assignment of a low potential is based on consideration of geologic environments where mineral and other resources might be expected.

Mine and prospect map of the Pusch Ridge Wilderness Area, Pima County, Arizona
The Endangered American Wilderness Act of 1978 created the Pusch Ridge Wilderness. During 1979, the U.S. Geological Survey and the U.S. Bureau of Mines investigated the area to evaluate the mineral resources. In addition to field investigations, studies by the Bureau of Mines personnel included courthouse research to ascertain claim locations within and near the area. Field work involved sampling and mapping located prospects. Rock samples were obtained from most of the working examined. A total of 55 samples were collected for assaying. All samples were fire-assayed for gold and silver, and at least one sample from each locale was checked by spectrographic analysis. Analytical results of all samples are available from the Bureau of Mines, Intermountain Field Operations Center, Denver Federal Center, Denver, Colorado 80225.
