Site is in Lake Clark National Park and Preserve.
Location: Approximately 5.6 km north of Kijik Mountain, near peak 3,180. Locality 19 of Nelson and others (1985) and locality 27 of MacKevett and Holloway (1977). Sec. 35, T. 4 N., R. 29 W., of the Seward Meridian. Locality accurate within 1.6 km.
Geology: Area of widespread zinc and trace lead anomalies associated with silicified zones in felsic volcanic rocks. Several zones of intense fracturing and iron-staining contain 1 percent to 3 percent pyrrhotite or pyrite. Samples taken from zones of intense fracturing and iron-staining yielded values of 220 to 260 ppm Zn (Resource Associates of Alaska, 1976). The volcanic rocks include: rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows (Nelson and others, 1983; unit Tv). Potassium-argon ages for Unit Tv range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).
Workings: Samples taken from zones of intense fracturing and iron-staining yielded values of 220 to 260 ppm Zn (Resource Associates of Alaska, 1976).
Age: Tertiary; volcanic host for mineralization has potassium-argon ages that range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
Alteration: Iron-staining, silicic alteration, and slight chloritic alteration of volcanic rocks (Resource Associates of Alaska, 1976).
Production: No production
