Location: The prospect is located in the SE1/4 section 12, T. 9 N., R. 2 W., of the Seward Meridian. It is at an elevation of 2,600 feet, and 1,000 feet N70W from the turn at the head of Bear Creek. This is location 11 of Tysdal (1978 [MF-880-A]) and location S-300 of Jansons and others (1984). The location is accurate to within a quarter of a mile.
Geology: The deposit consists of auriferous, sulfide-bearing, quartz veins that heal fractures in an Eocene(?) felsic dike. The veins are highly irregular, range to as much as 1 foot wide, and contain pyrite and arsenopyrite (Jansons and others, 1984). The dike generally strikes N15W and dips 55W (Hoekzema and Sherman, 1983) and also contains pyrite and arsenopyrite. The country rock is siltstone (Tysdal, 1978 [MF-880-A]) of the Valdez Group of Late Cretaceous age (Nelson and others, 1985).
Workings: The workings on this prospect consist of a single adit that is 90 feet long. The adit was mapped and sampled in 1982 by the U.S. Bureau of Mines (Hoekzema and Sherman, 1983). Three chip samples assayed only trace amount of gold and less than 0.05 ounce of silver per ton. A grab sample of dump material assayed 0.05 ounce of gold per ton and 0.03 ounce of silver per ton. There is no reported production.
Age: Eocene or younger, the probable age of the dike host rock.
