|Location and accuracy||This prospect is on Mineral Creek, a small south tributary to the upper Kluvesna River. It is at an elevation of about 3,500 feet in the NE1/4 of section 26, T. 1 S., R. 8 E. of the Copper River Meridian. This is locality 179 of MacKevett (1976); the location is accurate to within 1,000 feet. Cobb and MacKevett (1980) included this prospect under the name 'Mineral Cr.'.|
Geologic descriptionIn this area, many quartz veins up to 4 feet thick contain pyrite, chalcopyrite, and minor chalcocite (Moffit and Mertie, 1923; MacKevett, 1976). The veins are commonly less than 2 feet thick, are localized along faults showing post-vein displacement, and cut both Permian argillite and upper Jurassic granitic rocks. Assays show up to 3 ounces of both gold and silver per ton (Moffit and Mertie, 1923). The area was explored with several short adits and drifts.
