Information leading to the delineation of this focus area

Basis for focus area ARDF occurrences, prospective geology, geochemical anomalies.
Identified resources None.
Production None recorded.
Status Current and past exploration.
Estimated resources No published resources, however significant likelihood of resources at Fort Knox.
Geologic maps Sporadic 1:250,000 scale mapping across the region, with postage stamps of higher-quality map coverage.
Geophysical data Inadequate aeromagnetic and aeroradiometric coverage, will be partly addressed by planned Phase 1 Earth MRI coverage acquisition.
Favorable rocks and structures Evolved granites such as the Goodpastor, Gardiner Creek granites, aplitic, granite and pegmatitic ilmenite-series granites.
Deposits N/A: significant potential for future resource definition at Fort Knox.
Evidence from mineral occurrences ARDF occurrences include Fort Knox, Banner, Section 21, Quartz Porphyry, etc.
Geochemical evidence Anomalous HUC's for W, Ta, Au, Mo, Au in rock chips and stream sediments.
Geophysical evidence No data.
Evidence from other sources High prospectivity determination based on Karl and others, 2016.
Cover thickness and description Unknown.
Authors Douglas C. Kreiner, James V. Jones III, Melanie B. Werdon.
New data needs New mapping, geophysics, and updated geochemical sampling.
Geologic mapping and modeling needs Mapping at 1:100,000 scale or better.
Geophysical survey and modeling needs Aeromagnetics and radiometrics collected at Rank 2.
Digital elevation data needs IfSAR coverage is complete over entire focus area.
