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 (LG207).
Mineralization found in prospect pits consisted of bladed stibnite and pyrite with abundant antimony, arsenic and iron oxides (Smith, 1913). A 100-foot adit was driven below the prospect pits but did not intersect the mineralization seen in the pits.
Geologic map unit (-147.451047804897, 65.0642766655403)
Mineral deposit model Stibnite vein.
Age of mineralization Mid-Cretaceous by analogy with other mineralization in the area.

Production and reserves
