Location: Located on ridge southeast of Shishakshinovik Pass in T. 23 N., R. 12 E., Kateel River Meridian. Shown as location 52 in Mayfield and Grybeck (1978). Accurate to within 2000 ft. (600 m).
Geology: Minor amounts ofgalena, sphalerite and molybdenite in granite near contact. Deposit is 1. 5 mi. (2.4 km) long and up to 20 ft. (6 m) thick. Granite intrudes sequence of limestone, dolomite, shale, graphite schist, and quartz-chlorite schist; it probably is an apophysis of the Shishakshinovik pluton ( Mayfield and Grybeck, 1978).
Workings: Surface workings and high geochem anomalies in Pb, Zn and Mo Mayfield and Grybeck (1978). One float boulder found in drainage contained 5% galena, 10%-15% pyrite, and 3% sphalerite. Degenhart, (1978, p. 391) reported several analyses of samples: sample BM 1230 contained 630 ppm Pb and 400 ppm Zn; a 900 ft (305 m) chip sample of granite (BM 1226) contained 2% Pb, 1.65% Zn, and 3 oz./ton (102 g/ton) Ag. Other mineralized float samples observed in the area.
