Location and accuracy 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.

Geologic setting

Geologic description

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 (Brosgé and Reiser, 1964). This greenschist is in contact with a sliver of the Devonian(?) Horace Mountain pluton to the south and Devonian calcareous units to the north. Brosgé and Reiser (1972) included this occurrence in a group of anomalous stream-sediment and rock samples that show gold values and anomalous lead, zinc, copper, and silver. They imply an association between the above-described quartz vein sample and a sample of galena from a nearby prospect in limestone which returned values of 360 ppm Ag and 6.5 ppm Au. The location of the nearby prospect is not given.
