Key points
- The survey uses a modified Cessna 208A Caravan flying 100 to 150 feet above sea level across thousands of square kilometers of Gold Coast Resource’s offshore Ghana concessions.
- Two Scintrex CS-3 cesium magnetometers on the wingtips plus a triaxial fluxgate magnetometer on the tail stinger measure magnetic field strength and gradient to map geology beneath the seabed.
- The method targets magnetic signatures from minerals like magnetite that often accompany buried paleo channels and sedimentary environments where offshore alluvial gold may have accumulated.
- The video features Chris Payne, CEO of AiGeo, explaining the aircraft’s sensors and the airborne survey methodology.
