The mine is in the Wrangell-St. Elias National Preserve.
Location: This placer gold mine is on lower Bryan Creek, 2,500 feet northwest of hill 4615 and 6,500 feet southwest of peak 6075. The site is the approximate midpoint of 3,000 feet of placer workings outlined by Richter and Jones (1973). It is in the SW1/4 of section 16, T. 3 N., R. 19 E. of the Copper River Meridian. Cobb and Richter (1980) include this mine under the name 'Bryan Cr.'. This is locality 68 of Richter and others (1975) and National Park Service locality WRST-70 (unpublished data).
Geology: Richter and Jones (1973) show placer mine workings along about 2,500 feet of Bryan Creek. The creek was prospected in 1914 and is characterized by abundant native copper nuggets with the placer gold (Capps, 1916). The placer deposit is at least partly on a clay false bedrock. Bedrock exposed along the channel of Bryan Creek is Cretaceous volcanic and volcaniclastic rocks (Richter and Jones, 1973).
Workings: Richter and Jones (1973) show placer mine workings along about 2,500 feet of Bryan Creek.
