|Location and accuracy||The prospect is at an elevation of 1,300 feet, on the crest of the ridge about 1.2 miles northeast of Golden. It is located in the SW1/4 section 1, T. 10 N., R. 8 E., of the Seward Meridian. This is location 96 of Condon and Cass (1958), location 80 of Cobb and Richter (1972), location 96 of MacKevett and Holloway (1977), location 152 of Cobb and Tysdal (1980), and location S-135 of Jansons and others (1984). This location is accurate to within a quarter of a mile.|
The prospect is hosted in sheared graywacke and slate of the Valdez Group of Late Cretaceous age. The deposit consists of a single quartz vein carrying arsenopyrite and gold (Cobb and Tysdal, 1980). The vein is in an 8-foot-wide shear zone that strikes northeast and dips 70NW. The vein ranges from 2 to 8 inches wide. The workings on the prospect consist of a 6- by 9-foot open cut.The U.S. Bureau of Mines sampled this prospect in 1979. Two grab samples contained 0.75 ppm and a trace amounts of gold (Hoekzema and Sherman, 1983).
