AIRBORNE GEOPHYSICAL SURVEY

Objectives

• Perform airborne geophysical surveys over the Volta and Keta Basins over an area of 98,000 km²;

• Maintain the processing and interpretation skills of the GSD geophysicists;

• Test hypothetical possibilities of the occurrence of sediment-hosted base metal mineralization and diamondiferous kimberlites;

• Provide a geological framework to perform future geological mapping for mineral exploration and ground water resources.

Aircraft used for Magnetic and Radiometric Survey

Scope

• Phase1: geological outline through Radar and optical satellite imageries.

• Phase 2: airborne geophysical survey over the two basins for magnetics and spectrometry.

• Phase 3: airborne electromagnetic and magnetic geophysical survey of specific areas, following the completion and interpretation of phase 2, using fixed wing time domain technology.

• Phase 4: interpretation of the combined geology and geophysics.

• Phase 5: production of factual and interpretation maps.
