A mineral investigation in the nearly contiguous Black Butte and Elk Creek Roadless Areas of northern California, indicates that small parts of both roadless areas have a probable mineral-resource potential for small manganese-copper- or chromite-type deposits. There is little promise for the occurrence of energy resources in the areas. Investigation of geothermal resource potential and of the potential for other hydrothermal base- and precious-metal mineralization should be initiated.
