Status of Airborne Geophysics Data: Existing and Required
With the lack of detailed airborne geophysical data and numerous existing and new concessions to be awarded there is need for Area Wide Surveys and Proprietary Surveys.
Magnetics and Radiometrics:
Mining areas covered with 700m – 500m grids that need to be infilled to 200m – 100m and at 60m height
Needed for uranium and base metals, gold and copper exploration
Gravity (Gradiometer):
Significant lack of gravity data in general
Useful in general and for iron-ore exploration
Electromagnetics:
Significant lack of EM data in general
EM data in the greenstone belt and massive sulphide zones

Importance Of High Resolution Aeromagnetic Data
Click image to expand
Aeromagnetic data is used for exploration of gold and hydrothermal deposits:
Gold-rich areas are associated with changes in rock magnetism
Archean orogenic gold mineralization in areas of structural complexity
Major shear zones and faults form conduits for mineralising fluids
Shear zones and faults are associated with magnetite destructive alteration causing linear negative magnetic anomalies
Aeromagnetic data identifies lineaments as a reliable indicator of geological structures
Iron-rich magnetic units are host rocks for mineralisation due to their reactivity with gold-bearing fluids
