Economic information

Comments on the geologic information

  • Geologic Description = Eightmile Creek is one of several tributaries to the Bettles River in which placer gold has been reported. Little descriptive information is available for this creek, but Reed (1938) reported that very good prospects had been found and that mining had occurred near the mouth in the early 1900s. Joesting (1943) reported placer cinnabar on this creek. Reed (1938) reported schist bedrock near the mouth of the creek, but Dillon and others (1996) mapped Ordovician black phyllite and marble near the mouth and Ordovician to Cambrian(?) quartz-feldspar schist farther upstream.
  • Age = Quaternary.
