The Ragged Top Wilderness Study Area (AZ-020-197), for which mineral surveys were requested by the U.S. Bureau of Land Management, encompasses 4,460 acres in southcentral Arizona. Field work was carried out in 1987 by the U.S. Bureau of Mines and the U.S. Geological Survey to appraise the identified (known) resources and assess the mineral resource potential (undiscovered) of the wilderness study area. The study area includes the northern part of a mineralized area that includes the Silver Bell porphyry copper deposits. Despite this proximity to a major mine and the presence of several mines and prospects within and near the study area, no metallic resources were identified. Part of the southwest corner of the study area has high resource potential for gold, silver, lead, vanadium, barite, molybdenum, copper, and zinc in vein deposits. Adjacent parts of the study area to the north, west, and south have moderate resource potential for zinc, lead, barite, molybdenum, gold, silver, and copper in similar veins.
