The results of a mineral survey of the Cabinet Mountains Wilderness, Montana indicate areas of probable and substantiated resource potential for copper, silver, lead, zinc, and gold. No potential for other metals or energy resources was identified in this survey. The mineral-resource potential of the area was evaluated by interpretation of geologic mapping, geochemical, geophysical, and gravity surveys, and by examination of mines and prospects, these studies were conducted from 1972 to 1974. Exploration by private industry has resulted in discovery of significant copper-silver deposits in and adjacent to the wilderness.
