Comments on the geologic information

  • Geologic Description = This placer deposit is developed on weathered, coarse-grained, porphyritic biotite granite (Brooks, 1925, p. 19; Prindle, 1908, p. 40). Gold is derived from a mineralized zone near a contact between Cretaceous granite and schist (Brooks, 1911 [B 480, p. 69]). The paystreak was said to be narrrow (Prindle, 1908, p. 40). The alluvium consists of granitic sand about 8 feet deep (Prindle, 1908, p. 40). The gold varies from from 750 to 934 fine (Glover, 1950).
  • Age = Quaternary placer.

Economic information about the deposit and operations

Development status Past Producer
Commodity type Metallic

Comments on exploration

  • Status = Inactive

Mining district

District name Fairbanks

Comments on the production information

  • Production Notes = There probably was some minor production before 1908, and relatively modern tailings along the creek indicate some production in recent years.

Comments on the workings information

  • Workings / Exploration = Open-cut mining took place in the valley floor sometime before 1908 (Prindle, 1908, p. 40). Evidence for more recent mining is the placer tailings and a mine marked on the Fairbanks (D-1) NW topographic map on Hill Creek ,but no other information is available.
