A Cu-Au-Ag-Mn-Fe-Ba mine located on 6 claims in West-central sec. 28, T1S, R11W on 'Cemetary Ridge', 4 miles North of Clanton's Well, on BLM-administered land. Owned by Messrs. J.J. Collins & C. Johnson. NOTE: MRDS places this locality in sec. 30, T1S, R11W.
Mineralization is spotty and weak copper mineralization and staining, with minor gold and silver, and a gangue of iron and manganese oxides, quartz, gouge, and brecciated wall rock along fractures and faults cutting a small area of Mesozoic schist, Precambrian granite, and Cretaceous or Tertiary rhyolite porphyry and an irregular hornblendite dike. This dike ranges up to about 60 feet (18 meters) wide but pinches out in several places along its irregular strike. It consists mainly of coarsely crystalline hornblende, marked by numerous spots and irregular veinlets of secondary quartz. Near the veinlets the dike has been rather strongly epidotized.
Workings include 2 shallow shafts approximately 1,200 feet (375 meters) apart and a few surface cuts. No production record.
