A mineral survey of the Chama-southern San Juan Mountains Wilderness study area in Colorado revealed demonstrated coal resources in an area of substantiated coal resource potential and areas of probable resource potential for petroleum and metals including molydenum, copper, zinc, lead, and silver. The coal deposit that underlies the northwestern part of the study area at its westernmost extension requires further study for a more accurate determination of the coal resources that underlie the area. Drilling also is required to determine depth, magnitude, and tenor of the postulated porphyry deposit containing copper and molybdenum in the northernmost part of the study area. Geophysical surveys and detailed geologic mapping in advance of drilling are needed in the areas delineated as having potential for oil and gas resources.
