MIDDLE MOUNTAIN-TOBACCO ROOT ROADLESS AREA, MONTANA.
A mineral-resource survey of the northern part of the Tobacco Root Mountains, Montana determined that the area included in or enclosed by the Middle Mountain-Tobacco Root Roadless Area contains serveral areas of probable or substantiated mineral-resource potential. Most of the mineralized areas are located in or adjacent to intrusive rocks of Late Cretaceous age. Mineral resources are probably of three types: disseminated and stockwork copper and molybdenum in porphyry-type deposits; gold-silver-quartz veins; and gold-bearing silicified zones. No energy resources were identified in this study.
