Suklak Creek is the old name for this stream, and it was worked by 'Big Jim' Edwards. Much of the information in the primary reference is hearsay.
Location: Big Jim Creek is a west-flowing tributary into the southern lake of Twin Lakes, which are approximately 15 miles west of Chandalar. The location (SW1/4 sec. 2, T. 31 N., R. 7 W., of the Fairbanks Meridian) approximately coincides with locality 7 in DeYoung (1978). The location is accurate within a 1-mile radius.
Geology: This small placer mine produced native copper nuggets as well as gold (Reed, 1938). The amount of production is unknown, but it was probably quite small.
Workings: Worked by rocker and panning as late as 1937. No further information available.
Age: Quaternary.
Production: Small-scale placer mining for gold probably was sufficiently productive to cover wages.
