Alaska Kardex No. 031-61B (Kardex is a card file mining claim information system located at the State of Alaska DNR Public Information Center in Fairbanks).
Location: This site is at an elevation of about 4,800 feet, approximately 3 1/2 miles northwest of the junction of Thru Creek and the North Fork Chandalar River (SW1/4 sec. 5, T. 35 N., R. 5 W., of the Fairbanks Meridian); the location is accurate within a 1/2-mile radius.
Geology: The limited information about this prospect describes it as malachite and chalcopyrite in quartz veinlets in the Silurian and Devonian Skajit Limestone near its contact with the Upper Devonian Hunt Fork Shale (Grybeck, 1977; Brosg
Workings: Claims were staked in 1972 and 1976.
Age: Devonian(?) based on reported Early Devonian Pb/Pb zircon ages from the associated Baby Creek batholith and Horace Mountain plutons (Dillon and others, 1996).
Commodities (Major) - Cu
Development Status: None
