General area of interest is highly iron-stained with hematite and oxidized pyrite. Site is in Lake Clark National Park and Preserve.
Location: Locality is about 4 km northeast of the mouth of Currant Creek and includes the unnamed tributaries of Currant Creek. This is locality 26 of Nelson and others (1985) and locality 28 of MacKevett and Holloway (1977). Sec. 26, T. 3 N., R. 27 W., of the Seward Meridian. Accurate to within 1,600 meters, the occurence may extend up to 2.5 km downstream from the plotted point.
Geology: Mineralization is in form of disseminations and fracture fillings of pyrite and chalcopyrite in strongly iron-stained intermediate volcanics and in the neighboring hypabyssal granitic to granodioritic intrusives near contact of Tertiary granitic rocks and Tertiary volcanic rocks. Interpreted by Resource Associates of Alaska (1976) as a volcanic neck or breccia pipe, composed of highly fractured, silicified, and recrystallized volcanic rocks. Resource Associates of Alaska (1976) reported a nearby stream sediment sample with value of 1,200 ppm Cu.
Workings: Resource Associates of Alaska (1976) reported a stream sediment sample with value of 1,200 ppm Cu.
Age: Tertiary or younger.
Alteration: Volcanic rocks are silicified, recrystallized, and iron-stained.
Production: No production
Reserves: No reserves
Commodities (Major) - Cu
Development Status: None
Deposit Model: Porphyry Cu ? (Cox and Singer, 1986; model 17 ?)
