Location: The Hughes Bar placer mine is on the east bank of the Koyukuk River about a mile south of the village of Hughes. The exact location is problematic; for this record, the site is the location shown by Cobb (1972, [MF458]).
Geology: Fine gold has been mined from several bars along the Koyukuk River since at least the 1890's. Hughes Bar, with Florence and Tramway Bars (in the Wiseman quadrangle), were some of the better-known localities (Maddren, 1910). Smith (1913) concluded that the gold on these bars had been carried for a considerable distance. Maddren (1910) indicates that perhaps $4,000 in gold (about 200 ounces) has been produced from the Hughes Bar. No other information is available.
Workings: Surface mining.
Age: Quaternary.
