Geologic setting

Geologic description

Note: As of 2008, this site and several others in the vicinity are being explored as a single entity by Freegold Ventures Inc. (Freeman, 2008) Considerable new mineralization has been discovered that indicates this is part of a larger mineralized system that is described as a separate ARDF site (LG205).
On August 26, 1910, 2.5 tons of ore from the Stepovich prospect yielded $700 in gold (13.5 ounces of gold per ton) (Times Publishing Company, 1912). The only other reference to the Stepovich Mine is a map location shown by Chapin in 1914.
