New data needs Airborne geophysics, with additional specific mapping after geophysics.
Geologic mapping and modeling needs 1:24,000 scale maps to be published.
Geophysical survey and modeling needs High resolution aeromagnetic and aeroradiometric data to assist with framework geology such as structural features and contacts.
Digital elevation data needs Lidar complete.
