Comments on the geologic information

  • Geologic Description = The Liberty Creek placer mine was initially staked in 1934, and held for two years. In 1937, it was re-staked, and active from 1937 to 1941. It was staked again in 1977. In the 1930's, there was some hand placer mining at the site. The site is currently being mined for placer gold using mechanized methods (J.M. Messing, oral communication, 1998). The geology in the vicinity of Liberty Creek consists of Paleozoic and/or Precambrian biotite gneiss and schist (amphibolite facies), and a small area of greenschist-grade Paleozoic phyllite and schist (Foster, 1970; Foster and Keith, 1994).

Economic information about the deposit and operations

Development status Producer

Comments on exploration

  • Status = Active

Mining district

District name Fortymile

Comments on the production information

  • Production Notes = The mine had some small production during the 1930's. Mechanized mining began on a small scale in the 1970's. Larger scale mining was attempted in the early 1990's. The current activity is at a modest level (J.M. Messing, oral communication, 1998).

Comments on the workings information

  • Workings / Exploration = The site has been staked numerous times since 1934. It was initially staked in 1934, held for two years, and re-staked again in 1937. It was active from 1937 to 1941, and staked again in 1977. In the 1930's, there was some hand placer mining activity at the site. It is currently an active, mechanized, low-grade placer mine (J.M. Messing, oral communication, 1998).
