Location: Coal Creek is a west tributary to Sinuk River; the mouth of Coal Creek is about three-quarters of a mile upstream from where the Nome-Teller road crosses Sinuk River. Coal Creek is not identified by name on the current U.S. Geological Survey Nome C-2 quadrangle map. The mine is in the south 1/2 section 5, T. 9 S., R. 36 W., Kateel River Meridian. It is located to within about a quarter mile. This is locality 59 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).
Geology: The Coal Creek placer gold mine is developed on graphitic schist and coal-bearing Tertiary sedimentary rocks that may be downfaulted against schist. Herreid (1970, figure 1, p. 10) described the Tertiary sedimentary rocks as conglomerate with marble and schist fragments; coal beds are present in these sediments along Coal Creek. Collier and others (1908, p. 84) reported that the coal-bearing strata along Coal Creek had a northwest strike and dipped southwest at about 30 degrees. An adit driven in the west bank of Coal Creek crosscut layers of bitiminous coal about 16 inches thick that are separated and floored by fire clay layers. They proposed that the coal basin probably covered about one-half of a square mile. Placer gold was found in the gravels of Coal Creek as the creek was being prospected for coal (Collier and others, 1908, p. 217). Hydraulic mining was proposed for the creek with water from a source in the Kigluaik Mountains but was apparently never undertaken on a large scale. Some placer gold here may have been derived from reworking of the Tertiary sedimentary rocks.
Workings: Some small-scale surface placer gold workings are present. An adit was used to prospect coal beds in the area.
Age: Quaternary; gold may have been derived by rewoking of Tertiary sedimentary rocks.
