Geologic setting

Geologic description

Eakin (1914) reported that some placer gold had been recovered on the south bank of the Koyukuk River. Reed (1938) mentions a bar deposit on the lower Koyukuk River, opposite Red Mountain, similar to other bar deposits along the river. Six panned-concentrate samples from a gravel bar in this area all contained very fine- to fine-grained gold. The best sample had 1 fine and 12 very fine flakes of gold; the concentrate was analyzed and contains 3,848 ppb gold (Kurtak and others, 2002).
