|Location and accuracy||The prospect is located on the west side of Finski Bay in the W1/2 section 24, T. 11 S., R. 11 W., of the Copper River Meridian. This is location 186 of Tysdal (1978 [MF-880-A]) and location S-105 of Jansons and others (1984). This location is accurate to within half a mile.|
Geologic descriptionThe prospect is hosted in sheared pillow basalt and greenstone of the Orca Group of Tertiary age. It consists of three 0.5- to 1-foot-wide quartz veins. The veins contain pyrite and chalcopyrite (Cobb and Tysdal, 1980). The single working on the prospect is a 70-foot drift. The U.S. Bureau of Mines sampled this prospect in 1981; they collected two samples of vein material that contained 11 and 70 ppm copper (Jansons and others, 1984).
