MAZATZAL WILDERNESS AND CONTIGUOUS ROADLESS AREAS, ARIZONA.

A mineral survey has shown that the Mazatzal Wilderness, Arizona has demonstrated resources of silver, gold, lead and mercury, small areas of substantiated mineral-resource potential for silver and copper, and areas of probable resource potential for resources of silver, copper, lead, mercury, and molybdenum. Gold, silver, and copper resources occur in small deposits in the north-central, eastern, and southern parts of the wilderness. A small demonstrated mercury resource is located at the Sunflower mine near the southeastern corner of the wilderness adjacent to the well-known Sunflower mining district. Molybdenum mineralization found during this study in the Tangle Creek area west of the Verde River may extend eastward into the roadless area and the wilderness. Tin occurrences not previously known in the Mazatzal region were found in the central part of the wilderness, and uranium was found near Horseshoe Reservoir, but there is little promise for the occurrence of tin and uranium resources. No potential for fossil fuel resources was identified in this study.
