A former underground Cu-Ag-Au-Fe occurrence/prospect/mine located in the NE¼SW¼ sec. 32, T5S, R20E, G&SRM. Discovered 1902. Closed 1945.
Mineralization is ore hosted in the Pinal Schist and metavolcanics (brecciated Precambrian schist and rhyolite cemented by specularite). An associated rock unit is the Copper Creek Granodiorite. Ore control was a zone of brecciation.
Area structures include block faulting trending NNW. Regional trends: minor Pre-Cretaceous E- and NE-trending folds and major Post-Cretaceous NNW-trending faults.
Accurate Original Entry (1902): ^29.7% Cu. Last production was in 1902; 15 tons of ore at 29.5% Cu; several dollars in Au and Ag were reported from the Copper Bar and Sam Jones prospects.
