Location: The prospect is located in the SE1/4 section 8, T. 6 N., R. 2 W., of the Seward Meridian, at elevations between 4,200 and 4,400 feet. The site is about 2.2 miles east-northeast of Devils Pass. This is location 95 of Condon and Cass (1958), location 82 of Cobb and Richter (1972), location 94 of MacKevett and Holloway (1977), location 147 of Cobb and Tysdal (1980), and location S-258 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: The deposit at the North Star prospect consists of a vuggy, milky-white quartz vein (Hoekzema and Sherman, 1983). The vein, as exposed 200 feet above the portal of an adit, strikes N5E and dips 60NW, roughly parallel to the foliation of the Valdez Group (Late Cretaceous age) slate host rock (Nelson and others, 1985). The rock at the portal is blocky graywacke that breaks into brick- and flagstone-like fragments (Hoekzema and Sherman, 1983).
Workings: A trail leads to a caved adit (Jansons and others, 1984). The U.S. Bureau of Mines collected surface samples in 1979. A grab sample contained trace amounts of gold and silver. A 6-inch-long chip sample assayed 0.08 ounce of gold per ton and a trace of silver (Jansons, 1981).
Age: Cretaceous or younger; the vein cuts rocks of the Valdez Group of Late Cretaceous age.
