Report: Rock Creek Claim This small site was studied in detail by the U.S. Bureau of Mines (1988) because it is within the Electric Peak Wilderness Study Area. They found a N80E 85SE vein three feet wide containing pods of massive pyrite, arsenopyrite, galena, and sphalerite, and speculated that the property contained 15,000 tons of inferred subeconomic resources at .09 oz/ton gold and 3.44 oz/ton silver. Host rocks are latitic and andesitic Elkhorn Mountains Volcanics, which contain narrow alteration bands of kaolinite, chlorite, and pyrite about the vein. We also noted abundant calcite and siderite within the veins. Two dry caved adits are present, but the extent of the workings probably totals less than a few hundred feet.
