|Location and accuracy||The occurrence is located at an elevation of 1,500 feet and about a mile northwest of the head of Snug Harbor. It is located in the SE1/4 section 7, T. 2 N., R. 10 E., of the Seward Meridian, at an approximate elevation of 1,500 feet. This is location 141 of MacKevett and Holloway (1977), location 237 of Cobb and Tysdal (1980), and location S-42 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionNelson and others (1985) mapped bedrock in this area as Orca Group of early Tertiary age. The occurrence consists of a north-south-trending 30-foot-wide shear zone that cuts greenstone. The shear zone contains as much as 5 percent pyrrhotite and traces of chalcopyrite. A chip sample across the zone contained 14 ppm copper and 50 ppm zinc (Kurtak and Jeske, 1986).
