|Location and accuracy||Locality is about 4 km NE of mouth of Tazimina Creek on the western flank of a 1,495 m (~4,900 ft) high ridgeline. This is locality 37 of Nelson and others (1985) and locality 36 of MacKevett and Holloway (1977). SE1/4 sec. 20, T. 1 S., R. 27 W., of the Seward Meridian. Location is accurate within 800 m.|
Geologic descriptionDisseminated 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.
