| Basis for focus area |
ARDF occurrences, prospective geology, geochemical anomalies. |
| Identified resources |
None. |
| Production |
None recorded. |
| Status |
Unknown. |
| Estimated resources |
None. |
| Geologic maps |
No modern mapping better than 1:250,000 scale. |
| Geophysical data |
Partly (50%) adequate aeromagnetic coverage (Porcupine survey), other parts inadequate; inadequate aeroradiometric coverage. |
| Favorable rocks and structures |
Devonian and related evolved granitic rocks emplaced into continental margin successions including abundant carbonate. |
| Deposits |
None. |
| Evidence from mineral occurrences |
None. |
| Geochemical evidence |
None. |
| Geophysical evidence |
No data. |
| Evidence from other sources |
High prospectivity determination based on Karl and others (2016). |
| Comments |
This is a poorly mapped, geologic hole in the understanding of Alaska and contains a known peralkaline intrusive complex with REE-bearing minerals hosted in quartz veins and associated sparse placer workings suggesting upside prospectivity. |
| Cover thickness and description |
Unknown. |
