Location: This occurrence is about 4 miles west of St. James Bay. It is at an elevation of approximately 2,000 feet, near the terminus of a glacier at the head of a creek draining into St. James Bay. It is in the SW1/4 NW1/4 section 33, T. 37 S., R. 61 E. of the Copper River Meridian. The location is accurate.
Geology: This occurrence is in Silurian graywacke, turbidite, and limestone of the Point Augusta Formation (Brew and Ford, 1985). The deposit consists of pods and stringers of pyrite in siliceous argillite and in quartz veins. A U.S. Bureau of Mines sample of a quartz-calcite vein contained up to 4,000 ppm copper and 1,600 ppm zinc (Clough and Redman, 1989). The general area is underlain by metamorphosed Silurian and Devonian clastic rocks, limestone, and volcanic units; Permian limestone and siltstone; and small plutons of Tertiary and Cretaceous granodiorite (Brew and Ford, 1985).
Workings: Only surface sampling.
