Geologic setting

Geologic description

Disseminated chalcopyrite, azurite, malachite, manganese mineralization, and undefined Mo, Pb, and Zn minerals associated with the contact area between Tertiary basalt-andesite breccia and a Tertiary sequence of hypabyssal granites and granodiorites. Resource Associates of Alaska (1976) reported a one-foot-long channel sample assayed 103 ppm Ag, 20,000 ppm Cu, 107 ppm Mo, 17,000 ppm Pb, and 2,000 ppm Zn.

Production and reserves

Workings or exploration Resource Associates of Alaska (1976) reports a one-foot-long channel sample assayed 103 ppm Ag, 20,000 ppm Cu, 107 ppm Mo, 17,000 ppm Pb, and 2,000 ppm Zn.

Production notes No production

Additional comments

Best chance for significant deposits in this area is along the contact of basalt-andesite with granite (Resource Associates of Alaska, 1976). Site is in Lake Clark National Park and Preserve.
