This paper reports on the Ragged Top Wilderness Study Area in Arizona which contains Proterozoic granite and sedimentary rocks, Cretaceous volcanic rocks and granodiorite porphyry, and Tertiary rhyolite. Part of the Silver Bell Caldera is included in this study area. No metallic resources were identified. The southwest corner has a high and a moderate resource potential for gold, silver, lead, vanadium, barite, molybdenum, copper, and zinc in vein deposits. The east side has a low resource potential for these elements. Parts of this study area have a moderate potential for copper, silver, gold, and molybdenum in porphyry copper deposits, a low potential for uranium deposits in sedimentary rocks, and a low potential for thorium, rare-earth elements, quartz, feldspar, and mica in granite.
