|Location and accuracy||The prospect is at an elevation of 1,000 feet on the north side of Siwash Bay. It is in the SW1/4 section 11, T. 10 N., R. 11 E., of the Seward Meridian. This is location 87 of Cobb and Richter (1972), location 112 of MacKevett and Holloway (1977), location 181 of Cobb and Tysdal (1980), and location S-119 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
Geologic descriptionThe only information about this occurrence is that it is a copper prospect, possibly a massive sulfide occurrence, in sedimentary rock of the lower Orca Group of Tertiary age (Cobb and Tysdal, 1980).
