Yolla Bolly-Middle Eel Wilderness And Big Butte-Shinbone, East Fork, Murphy Glade, and Wilderness contiguous roadless areas, California

A mineral survey of the Yolla Bolly-Middle Eel Wilderness, California identified a mine with inferred resources of manganese and an occurrence with inferred resources of nickel. The adjacent Big Butte-Shinbone Roadless Area to the west has an area of probable potential for the occurrence of chromium-nickel-cobalt resources and mines with demonstrated and inferred resources of manganese and chrome-nickel-cobalt. The known deposits are small and low grade. The East Fork, Murphy Glade, and Wilderness Contiguous Roadless Areas are considered to have little promise for the occurrence of mineral resources. The geologic terrane precludes the occurrence of fossil fuel resources.
