Geologic mapping and geochemical sampling show that the eastern third of the Lusk Creek Roadless Area in Illinois has a substantiated resource potential for fluorspar, lead, zinc, and barite, and other parts of the area have a probable resource potential for fluorspar. Fluorspar, which occurs along fault zones in the eastern part of the area, has been produced in the adjacent Illinois-Kentucky fluorspar district. There is little promise for the occurrence of other mineral or energy resources.
