Location: Maddren (1915) located this placer prospect near the Tuluksak River about 5 miles downstream from the mouth of Granite Creek (BH015). The coordinates given here are at about this location, about 0.6 mile southwest of the center of section 12, T. 10 N., R. 62 W. However, there is no other reference to this prospect and its exact location is uncertain. This is locality 9 of Cobb (1972 [MF 455]) and of Hoare and Cobb (1977).
Geology: Maddren (1915) reported that fine gold was found in a 50-foot prospect shaft through frozen ground near the Tuluksak River about 5 miles below the mouth of Granite Creek (BH015). The prospect is on the lower part of the river, where the gradient decreases as it enters onto the lowlands of the lower Kuskokwim River. The low elevation and proximity to the Kuskokwim River lowlands suggest that Quaternary sea level fluctuations could have influenced placer development on the lower Tuluksak River. There apparently has been no other work on the Tuluksak River below the mouth of Granite Creek.
Workings: A 50-foot prospecting shaft was dug before 1915 through frozen ground.
Age: Quaternary.

Commodities (Major) - Au
Development Status: None
