| 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. |
