Location: The occurrence is located in the SW1/4 section 34, T. 1 N., R. 1 E., of the Seward Meridian. It is situated at an elevation of about 2,400 feet on the southeast side of the southwest terminus of Godwin Glacier, southeast of peak 5265. This is location 92 of Cobb and Tysdal (1980) and location S-195 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: Nelson and others (1985) described the host rock for this occurrence as pale to leek-green aphyric to porphyritic pillow basalt with subordinate pillow breccia, tuff, and siltstone. Bedrock in the area is the Valdez Group of Late Cretaceous age. The occurrence consists of two veins. One is a massive sulfide vein that is composed of solid pyrrhotite with disseminated chalcopyrite (Grant and Higgins, 1909). The other is quartz vein, as much as 8 feet wide, contains copper and gold. No assay results are reported in the literature.
Workings: No workings, improvements, or assay results are reported.
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.
Commodities (Major) - Au, Cu
Development Status: None
Deposit Model: Cyprus massive sulfide (Cox and Singer, 1986; model 24a)
