Comments
Comment (Workings): Workings / Exploration = Grab sample of limonite-stained material (USGS OF 398, sample 848) contained 50 ppm Ag, 100 ppm Cu, more than 10,000 ppm Pb, more than 10,000 ppm Zn. Type of workings: surface
Comment (Deposit): Model Name = Lode: breccia pipe
Comment (Geology): Geologic Description = Zone of intense hydrothermal alteration containing fragments of volcanic rock cemented by quartz carrying pyrite, galena, sphalerite and chalcopyrite. Country rock is mapped as Tertiary porphyry complex, but may include argillite and limestone of Permian age, gabbro dikes and sills of Triassic age, and rocks of the Pennsylvanian-Permian Tetelna Volcanics
Comment (Exploration): Status = Inactive
