Alaska Kardex No. 031-27 (Kardex is a card file mining claim information system located at the State of Alaska DNR Public Information Center in Fairbanks).
Location: The reference point for this prospect is at an elevation of about 2,000 feet near the east end of Reds Lake approximately 24 miles north of Chandalar (sec. 24, T. 34 N., R. 5 W., of the Fairbanks Meridian). Its location is somewhat speculative because it is derived from a sample collected around 1900. This occurrence is listed in several publications (Cobb, 1976, [OFR 76-340]; DeYoung, 1978; Cobb and Cruz, 1983) as some variant of Chandalar River, North Fork. The location is accurate within a 1-mile radius.
Geology: This prospect is described only as a sample of a quartz vein, collected prior to 1900, which assayed 0.42 oz Au and 0.14 oz Ag (Schrader, 1900). The country rock near this prospect is a relatively large outcrop area of albite-epidote-chlorite-muscovite greenschist (Brosg
