Location and accuracy This placer gold mine is reported to be on a bench near the mouth of Chicago Creek (Mendenhall, 1902). Chicago Creek is an east tributary to Kugruk river. The mouth of Chicago Creek on Kugruk River is 4,000 feet downstream of the Chicago Creek coal mine. This site is approximately located and is only known within one mile. It is locality 62 of Cobb (1972; MF 417; 1975; OFR 75-429).

Geologic setting

Geologic description

This placer gold mine is reported to be on a bench near the mouth of Chicago Creek (Mendenhall, 1902) and some mining took place in 1906 (Brooks, 1907). The exact location and the nature of the deposit has not been described. Bedrock in the area is extensively covered by tundra but it is probably part of a Lower Paleozoic metasedimentary assemblage (Till and others, 1986). Tertiary coal-bearing sediments are locally exposed along Kugruk River upstream from Chicago Creek.
