Geological map of the Kangankunde carbonatite pipe in Malawi, showing a km-scale intrusion and clear concentric ring-like lithological zonation and structure. This illustrates the necessity for multiple geological drillholes for proof of concept for a relatively simple carbonatite model.

D Inversion of Aeromagnetic data for Target i10 with AMT section and planned drillholes. The causative geology for the magnetic signatures is interpreted to be close to surface. The depth of overburden from this AMT section is interpreted to be ~120m. This target in interpreted as a simple single phase carbonatite phase/pipe with a possible outer ring indicated by a weak magnetic low.
