Structure: Fault
Alteration: Silicification
Deposit: Workings penetrate a large silicified outcrop on the bradshaw fault zone. The silicified rock dips about 35 NE and is elongate nw-se parallel to the fault zone. The rock is similar to that in the atlanta mine except that it has fewer open spaces. Breccia fragments appear to be completely silicified carbonate rock. The deepest portions of the mine penetrate carbonate beds which have been silicified intact with only minor brecciation. No sulfide minerals were found but limonite present in open spaces has probably been derived from oxidation of pyrite. Sampling done by standard slag co indicates widespread Au and Ag mineralization present at the bradshaw mine. Invisible U minerals are present, but a radiometric survey of the mine dump in 1978 indicates anomalous radioactivity.
Geology: Ore in 2 zones of red jasperoid a western zone 500 feet long and 150 feet wide, eastern zone is smaller narrow n60 W stringers and crevices carry oxidized Ag minerals
Ore(s): Fault, Fractures
