Location: The occurrence is located about three-quarters of a mile from the north side of Grant Lake at an elevation of about 3,000 feet. It is situated in the SE1/4 section 26, T. 5 N., R. 1 E., of the Seward Meridian. This is location 67 of Cobb and Tysdal (1980) and location S-229 of Jansons and others (1984). This location is accurate to within a quarter of a mile.
Geology: The occurrence consists of abundant thin quartz veins in a reddish-brown schist that is mapped as the Valdez Group of Late Cretaceous age (Tysdal, 1978 [MF-880A]). The veins are within a shear zone that may be associated with the Placer River fault system. A single grab sample contained 3 ppm silver, 1,000 ppm copper, 700 ppm vanadium, 500 ppm chrome, 300 ppm cobalt, 200 ppm zinc, and 100 ppm nickel (Tysdal, 1978 [MF-880-A]).
Workings: A single grab sample contained 3 ppm silver, 1,000 ppm copper, 500 ppm chrome, 700 ppm vanadium, 300 ppm cobalt, and 200 ppm zinc (Tysdal, 1978 [MF-880-A]).
Age: Cretaceous or younger; the veins cut rocks of the Valdez Group of Late Cretaceous age.
