|Location and accuracy||This placer mine is on Willow Creek, a north tributary to lower Ahtell Creek. It is at an elevation of about 2,700 feet, about 0.9 mile upstream of the junction of Ahtell Creek. The site is very close to the northeast corner of the Nabesna C-6 quadrangle. This is locality 60 of Richter and others (1975). It is located to within a few hundred feet. Cobb and Richter (1980) included this mine under the name 'Willow Cr.'.|
Geologic descriptionA small placer gold mine on Willow Creek was apparently worked and abandoned in the 1930s (Richter, 1964). If this deposit is similar to other gold placers in the area, the gold is probably rough, wiry, or dendritic and it may have been associated with wiry native silver and native copper (Moffit, 1954; Richter, 1964; 1966). Bedrock in Willow Creek is dominantly andesitic volcanic rocks of the upper Paleozoic, Tetelna Volcanics but felsic plutonic rocks of the Ahtell pluton are exposed about 2 miles to the west (Richter, 1966; 1976).
