The locality is in the Wrangell-Saint Elias National Park and Preserve.
Location: This mine is on the south valley wall of the Chitistone River east of the lower part of Lime Spring Creek. It is at an elevation of about 3,200 feet, 3,500 feet northwest of elevation 5615, about 1,000 feet south of the center of section 11, T. 5 S., R. 16 E. of the Copper River Meridian. This is locality 73 of MacKevett (1976); the location is accurate to within a few hundred feet. Cobb and MacKevett (1980) included this mine under the name 'Peavine'.
Geology: The deposit at this mine consists of malachite and azurite with some chalcocite that occurs in a brecciated fault zone that cuts both Triassic Chitistone Limestone and underlying Triassic Nikolai Greenstone (Miller, 1946; MacKevett and Smith, 1972; MacKevett, 1976). A small amount of mineralized material was shipped in the winter of 1973-74 (MacKevett, 1976). The mine was developed by a short adit and surface workings. Copper mineralization is common in Nikolai Greenstone and is thought to have accompanied regional deformation and low-grade metamorphism in the Late Jurassic to Early Cretaceous (MacKevett and others, 1997).
Workings: The mine was developed by a short adit and surface workings.
