|Location and accuracy||The prospect is located on the west slope of a mountain about 2 miles south of Golden at an elevation of 1,500 feet. It is in the W1/2 section 23, T. 10 N., R. 8 E., of the Seward Meridian. This is location 112 of Condon and Cass (1958), location 76 of Cobb and Richter (1972), location 162 of Cobb and Tysdal (1980), and location S-127 of Jansons and others (1984). This location is accurate to within half a mile.|
The prospect is hosted in sheared graywacke and slate of the Valdez Group of Late Cretaceous age. The deposit is in a 2- to 5-foot-wide shear zone and consists of lenses and stringer veins of quartz as much as 2 feet wide (Tysdal, 1978 [MF-880-A]). The shear zone dips vertically and is traceable for 300 feet along a northeast strike. The veins contain arsenopyrite, galena, pyrite, sphalerite, and gold (Johnson, 1914 [B 592-G, p. 225]).The workings on the prospect consist of a 155-foot adit; improvements in the early 1900s included an arrastre mill and cabin (Johnson, 1914 [B 592-G, p. 225]).

|Workings or exploration||The workings on the prospect consist of a 155-foot adit; improvements in the early 1900s include an arrastre mill and cabin (Johnson, 1914 [B 592-G, p. 225]). No assay results are reported. The U.S. Bureau of Mines searched for the prospect in 1979 and 1980 but did not locate it (Hoekzema and Sherman, 1983).|
