|Location and accuracy||The prospect is located in the NW1/4 section 20, T. 7 N., R. 9 E., of the Seward Meridian. It is situated on or near the northwest shore of South Bay on the south side of Perry Island. This is location S-99 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe prospect consists of a 4- by 8-foot open cut on 2- to 3-inch-wide epidote veins in granite (Jansons and others, 1984). Tysdal and Case (1979) mapped the rocks in this area as Eocene granite and granodiorite. Iron-stained veins have silicified the surrounding wall rock. The U.S. Bureau of Mines collected samples from this prospect that contained as much as 1 ppm copper (Jansons and others, 1984).
