New data needs Geologic mapping at 1:24,000 scale; airborne geophysics; evaluate locations on lidar.
Geologic mapping and modeling needs Geologic mapping following geophysics.
Geophysical survey and modeling needs High resolution aeromagnetic and aeroradiometric data to assist with framework geology such as structural features and contacts. Can aeromagnetic data detect iron associated with the deposits?
Digital elevation data needs Lidar complete.
