New data needs Rock geochemistry, detailed mapping, geophysics.
Geologic mapping and modeling needs No modern 1:24,000 scale mapping exists.
Geophysical survey and modeling needs Inadequate Rank 4 and 5 aeromagnetic and radiometric data; Rank 1 data would be useful.
Digital elevation data needs Lidar complete.
