Mineral resource potential map of the Hells Hole further planning area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico
During 1979, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to evaluate the mineral resource potential of the Hells Hole Further Planning Area. The investigations included geologic mapping, geophysical studies, geochemical sampling, and a survey of known mines, prospects, and mineralized areas. This report summarizes the results of those studies.
