Location and accuracy This prospect is along Willow Creek, a headwater tributary of Cleary Creek. It is about 1.2 miles north-northwest of Cleary Summit in the SW1/4NE1/4 sec. 25, T. 3 N., R. 1 E., of the Fairbanks Meridian. The location is accurate to within 2,000 feet.

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).
The only published information on this prospect states that some rich gold ore was extracted prior to 1910 (Brooks, 1911). The prospect was clearly distinct from the nearby Tolovana mine (ARDF no. LG110) at that time, but may have been developed with the Tolovana mine later. No information is available on the character of mineralization.
Geologic map unit (-147.457047551331, 65.062176561338)
Mineral deposit model Gold-quartz vein.
Age of mineralization Probably about 90 Ma based on analogy with similar gold deposits nearby.
