Location and accuracy This Fox Creek, with headwaters in the uplands of Atlakumtsitak Mountain, is an east tributary to Slate Creek (GO020). The placer mine location is about 2 miles upstream of the confluence of Fox and Slate Creeks, at the mouth of a small unnamed west tributary (Fechner, 1988, fig. 5). It is locality 15 of Hoare and Cobb (1977) and of Cobb and Condon (1972).

Geologic setting

Geologic description

A small amount of placer gold mining has taken place on Fox Creek; minor production was reported in 1936 (Smith, 1938). This east tributary to Slate Creek (GO020) is called 'Fox Gulch' by Hoare and Cobb (1977). The location of workings was plotted by Fechner (1988, fig. 5), who estimated that about 20,000 yards of material had been mined. The deposit was on a low bench along the east side of the stream, where 6 to 7 feet of gravel covered a small, 100- by 200-foot area of pay on bedrock. The average grade was reported to be 0.08 ounce of gold per cubic yard (Roehm, 1937). The gold was coarse, smooth and bright. Fechner (1988) collected 5 samples of sediment along about 3 miles of Fox Creek; these samples contained a trace to 0.0003 ounce of gold per cubic yard. Bedrock in the area includes Paleozoic and Mesozoic sedimentary and volcanic rocks, locally intruded by Upper Cretaceous to Lower Tertiary granitic rocks and Jurassic mafic/ultramafic plutonic rocks (Hoare and Coonrad, 1978).

Production and reserves

Workings or exploration The location of workings was plotted by Fechner (1988, fig. 5), who estimated that about 20,000 yards of material had been mined. The deposit was on a low bench along the east side of the stream, where 6 to 7 feet of gravel covered a small, 100- by 200-foot area of pay on bedrock. The average grade was reported to be 0.08 ounce of gold per cubic yard (Roehm, 1937).
Indication of production Yes; small
Production notes Fechner (1988, Figure 5) estimated that about 20,000 yards of material had been mined. As the average grade was reported to be 0.08 ounce of gold per cubic yard (Roehm, 1937), production could have been 1,600 ounces of gold. This is considered a maximum estimate of production.
