Location: The prospect is located near the head of Cedar Bay in the N1/2 section 8, T. 10 N., R. 12 E., of the Seward Meridian. This is location 184 of Tysdal (1978 [MF-880-A]) and location S-116 of Jansons and others (1984). This location is accurate to within half a mile.
Geology: The prospect is a 6- to 70-foot- wide shear zone in silicified graywacke and Eocene muscovite-bearing granite. The zone contains quartz veins carrying chalcopyrite, covellite, pyrite, and sphalerite (Jansons and others, 1984). The largest vein is 20 centimeters thick and 1 to 1.5 meters long. It contains mostly pyrite along with traces of chalcopyrite and covellite (Tysdal, 1978 [MF-880-A]). The single working on the prospect is a 700-foot adit. Three grab samples collected by the U.S. Bureau of Mines contained from 30 to 825 ppm copper (Jansons and others, 1984).
Workings: The single working on the prospect is a 700-foot-long adit. Three grab samples collected by the U.S. Bureau of Mines contained from 30 to 825 ppm copper (Jansons and others, 1984).
Age: Eocene or younger; the shear zone cuts Eocene granite.
Alteration: Silicification.
