Location: Coarse Gold Creek is a west tributary to Kougarok River. Its mouth is 2 miles west of the Nome-Taylor road measured from just north of where it crosses North Fork (Kougarok River). Sainsbury and others (1969) show placer mine workings to be present along 2,000 feet of the drainage starting 1,000 feet upstream of its mouth on Kougarok River. This is locality 33 of Cobb (1972; MF 417; 1975; OFR 75-429).
Geology: Little is reported concerning placer gold on central Coarse Gold Creek. Gold was reported and some mining took place somewhere on the creek by 1908 (Collier and others, 1908; Smith, 1909). Sainsbury and others (1969) show placer mine workings to be present along 2,000 feet of the drainage starting 1,000 feet upstream of its mouth on Kougarok River. Bedrock is not exposed in the area of these workings. The diorite in bedrock referred to in early reports (Collier and others, 1908) is probably metadiabase or metagabbro of the mafic metavolcanic assemblage of the region, considered to be Ordovician by Till and others (1986). As Sainsbury and others (1969) show some metagabbroic rocks in bedrock upstream where other placer mining took place on this creek (BN023), the early reports may be for upstream locations rather than for the area at the mouth (locality 33 of Cobb, 1972, MF 417).
Workings: Sainsbury and others (1969) show placer mine workings to be present along 2,000 feet of the drainage starting 1,000 feet upstream of the creek's mouth on Kougarok River.
