Geographic coordinates

Geographic coordinates: -161.2327, 59.30927 (WGS84)
Relative position Slate Creek is a north tributary to Goodnews River. This location is on Slate Creek just below the mouth of Wattamuse Creek (GO021) and just east of the local airstrip. The location of at least some placer mining on Slate Creek is assumed to be close to and downstream of that on Wattamuse Creek. This mine is included in locality 13 of Hoare and Cobb (1977) and of Cobb and Condon (1972).

Comments on the geologic information

  • Geologic Description = The principal placer gold producer in the area, Wattamuse Creek (GO021) flows into Slate Creek, a north tributary to Goodnews River. Parts of Slate Creek near Wattamuse Creek have been extensively drilled and explored and apparently placer mined (Hoare and Cobb, 1977). Some of the placer ground near Wattamuse and Slate Creeks includes bench deposits (Smith, 1934, p. 46-47). Between Wattamuse and Fox Creeks, the Slate Creek drainage has about 7 to 8 feet of gravel and has been prospected with encouraging results (Reed, 1931), although mining has apparently not taken place. Fechner (1988) noted that some small-scale mining has taken place on Slate Creek above Fox Creek (GO042). He collected 7 sediment samples along about 6 miles of the drainage above the mouth of Wattamuse Creek. The gold content of these samples ranged from undetectible to 0.0014 ounce 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).
