Location: This mine is located in the SW1/4 section 7, T. 9 N., R. 1 W., of the Seward Meridian. It is situated on Bear Creek at an elevation of 2,200 feet. This is location 5 of Cobb and Richter (1972), location 5 of MacKevett and Holloway (1977), location 10 of Cobb and Tysdal (1980), and location S-301 of Jansons and others (1984). The location is accurate to within 300 feet.
Geology: The deposit at this mine consists of an auriferous, sulfide-bearing, quartz-calcite vein as much as about 16 inches thick. The vein is hosted in sandstone of the Valdez Group of Late Cretaceous age and Eocene(?) felsic dikes (Cobb and Tysdal, 1980). The vein contains arsenpyrite, pyrite, galena, sphalerite, an unknown copper mineral, and gold. Workings consist of a 30-foot-deep flooded shaft and a 6-foot adit about 625 feet west of the shaft (Hoekzema and Sherman, 1983).
Workings: The workings consist of a 30-foot shaft with a small drift that filled with water during mining and a 6-foot adit about 625 feet west of the shaft . A five-stamp mill was erected between 1912 and 1914, but not enough ore was found and the mill was removed (Tuck, 1933). The U.S. Bureau of Mines sampled the dump of the mine in 1981 (Hoekzema and Sherman, 1983); the two grab samples they collected contained 6.2 ppm and 0.86 ppm gold and 24.7 and 1.7 ppm silver.
Age: Eocene(?) or younger; the vein cuts Eocene(?) felsic dikes.
Alteration: Both the dikes and sandstone show sericitic alteration (Cobb and Tysdal, 1980).
Production: No recorded production (Jansons and others, 1984).
Commodities (Major) - Au; (Minor) - Cu, Pb, Zn
