Comments on the geologic information

  • Geologic Description = The Montana placer prospect consists of a left-limit bench on Montana Creek over a distance of about 2 miles (3.2 km). Overburden ranges from 20 to 40 feet (6 m to 12 m) thick, and auriferous gravels average about 10 feet (3 m) thick. Reconnaissance drilling suggests that most values are on bedrock. The auriferous gravels are overlain by Quaternary eolian and colluvial deposits (Thorson and Guthrie, 1982). The Montana Creek Placer deposit is inferred to be Pleistocene, based on isotopically dated Quaternary units in Colorado Creek (Thorson and Guthrie, 1982).
  • Age = the Montana Creek Placer deposit is inferred to be Pleistocene, based on isotopically dated Quaternary units in Colorado Creek (Thorson and Guthrie, 1982).

Economic information about the deposit and operations

Development status Prospect

Comments on exploration

  • Status = Active

Mining district

District name Innoko

Comments on the production information

  • Production Notes = No production records have been found. In 1996 and 1997, a small exploration camp was being assembled at Colorado Creek for a placer drilling program on Montana Creek.

Comments on the workings information

  • Workings / Exploration = The prospect was first mentioned by Mertie (1936). According to Steve Neirod and Ron Rosander (oral commun., 1982), a reconnaissance churn drilling program in the 1950s conducted by Strandberg and Sons Mines Inc. encountered a low grade gold-bearing paystreak of unknown extent.
