Mineral resources of the Little Wood River Wilderness Study Area, Blaine County, Idaho

The Little Wood River Wilderness Study Area is in south-central Idaho 12 mi west-northwest of Hailey. This study area consists of Paleozoic sedimentary rocks overlain by Tertiary volcanic rocks. The parts of this study area that are underlain by Paleozoic rocks have moderate mineral resource potential for silver, barite, copper, lead, zinc, gold, and tungsten in epithermal deposits. The resource potential for other undiscovered metals, oil and gas, geothermal uranium, sand and gravel, and building materials is low.
