Evidence from mineral occurrences Potential from mineral system/deposit type.
Geochemical evidence Unknown.
Geophysical evidence Unknown.
Evidence from other sources Unknown.
Comments Broadly permissive for large igneous province conduit-type Ni-Cu-PGE mineralization and stratiform PGE enrichment (Skaergaard-type stratiform mineralization).

New data needs Geophysical data.
Geologic mapping and modeling needs Geologic mapping could be improved.
Geophysical survey and modeling needs High resolution aeromagnetic and aeroradiometric coverage. Aeromagnetic data expected to image mafic rocks and associated structures, radiometric data can help with geologic mapping in vegetated terrane; alteration may be imaged. Electromagnetic methods may help image sulfides.
Digital elevation data needs Lidar adequate.
