Wilderness study area, mineral resources of the Sleeping Giant, Lewis and Clark County, Montana
- US Geological Survey (US)
- US Bureau of Mines (US)
A Mineral resource survey was conducted in 1987 by the U.S. Geological Survey and the U.S. Bureau of Mines to evaluate mineral resources (known) and mineral resource potential (undiscovered) of the Sleeping Giant Wilderness Study Area (MT-075-111) in Lewis and Clark County, Montana. The only economic resource in the study area is an inferred 1.35-million-ton reserve of decorative stone (slate); a small gold placer resource is subeconomic. A high resource potential for decorative slate exists directly adjacent to the area of identified slate resource and in the northeastern part of the study area. The rest of the study area has a low potential for decorative slate. The westernmost part of the study area has a moderate resource potential for copper and associated silver in state-bound deposits in green beds and limestone; potential is low in the rest of the study are. The study area has a low resource potential for sapphires in placer deposits, gold in placer deposits (exclusive of subeconomic resource mentioned above), phosphate in the Spokane Formation, diatomite in lake deposits, uranium, oil, gas, geothermal energy, and no resource potential for phosphate in the Phosphoria Formation.
