Location: The occurrence is located just east of the north summit of Andy Simons Mountain at an elevation of 5,100 feet. It is situated in the SW1/4 section 33, T. 4 N., R. 1 E., of the Seward Meridian. This is location S-222 of Jansons and others (1984). This location is accurate to within 300 feet.
Geology: Country rock in this area is siltstone and slate of the Valdez Group of Late Cretaceous age (Nelson and others, 1985). The occurrence consists of a 1- to 1.5-foot-wide quartz vein that strikes N65E and dips vertically (Hoekzema and Sherman, 1983). Metallic minerals consist of chalcopyrite, galena, pyrite, and sphalerite. Two grab samples assayed 0.06 and 0.08 ounce of gold per ton and 0.16 and 0.25 ounce of silver per ton (Jansons and others, 1984).
Workings: There are no workings or improvements reported in the literature. Two grab samples assayed 0.06 and 0.08 ounce of gold per ton and 0.16 and 0.25 ounce of silver per ton (Jansons and others, 1984).
Age: Cretaceous or younger; the vein cuts rocks of the Valdez Group of Late Cretaceous age.
Reserves: The U.S. Bureau of Mines estimated a resource of 50 tons of ore containing 0.076 ounces of gold per ton, and 0.2 ounces of silver per ton (Hoekzema and Sherman, 1983).
