Location: The prospect is located on the southwest side of the head of Mallard Bay. It is in the NW1/4 section 12, T. 2 N., R. 9 E., of the Seward Meridian. This is location 232 of Cobb and Tysdal (1980) and location S-47 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: The country rock in this area is greenstone of the Orca Group of early Teriary age (Cobb and Tysdal, 1980). No workings are reported, although Johnson (1919 [B 692-C, p. 144, 146]) reported a test shipment of 20 tons of ore that contained 1,452 pounds of copper. The U.S. Bureau of Mines examined this area in 1981 and found chalcopyrite-pyrrhotite bearing greenstone float but no workings. Samples collected by the U.S. Geological Survey from an open cut contained as much as 0.5 percent copper and 0.3 percent nickel (Kurtak and Jeske, 1986).
Workings: No workings are known, but Johnson (1919 [B 692-C, p. 144, 146]) reported a test shipment of 20 tons of ore that contained 1,452 pounds of copper.
