A mineral survey of the Golden Trout Wilderness, California revealed that four areas in the wilderness have resource potential for tungsten and base and precious metals. One, the Mineral King pendant, has substantiated potential for tungsten deposits; the others are designated as having probable resource potential for tungsten and base and precious metals. Demonstrated tungsten resources exist at the Pine Tree mine, a skarn deposit in the Mineral King pendant. There is no evidence for the existence of large undiscovered deposits within the wilderness. The geologic terrane precludes the occurrence of organic fuel resources.
