Location: The occurrence is about 0.5 mile northwest of the summit of hill 2301 in the SE1/4 section 33, T. 11 N., R. 12 E., of the Seward Meridian. This is location S-117 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: The occurrence is in graywacke and consists of a 10-foot-wide shear zone containing quartz veins carrying chalcopyrite and pyrite (Jansons and others, 1984). Nelson and others (1985) mapped the bedrock in this area as Valdez Group of Late Cretaceous age. This occurrence was discovered by the U.S. Bureau of Mines. They collected a grab sample that contained 0.6 percent copper and 26 ppm silver (Jansons and others, 1984).
