New data needs Geologic mapping, and geochemical analyses.
Geologic mapping and modeling needs 1:24:000 scale geologic mapping.
Geophysical survey and modeling needs Rank 1 or Rank 2 aeromagnetic and radiometric coverage. Aeromagnetic data may image mafic rocks, associated structures, and possibly alteration zones. Radiometric data can help with geologic mapping in vegetated terrane.
Digital elevation data needs Lidar complete.
