Gandau 2

The large target in this licence area is the Kanoma Granite which is an ovoid intrusion belonging to the ‘older granite’ suite of late Proterozoic to early Palaeozoic age. The Kanoma Granite measures 9 x 4km and is a striking feature both in the field and on satellite imagery. The ‘older granite’ suite characteristically hosts pegmatitic phases in veins and marginal accumulations. These pegmatites are highly radioactive and contain significant quantities of columbite/ tantalite which is a major source of niobium and tantalum. Pegmatites can also be host to uranium mineralisation.

EcoPhoenix’s approach to finding economically viable quantities of columbite/tantalite and possibly uranium involves:
• Field geological and structural mapping
• Stream sediment and soil geochemistry
• Field Gamma Ray spectrometry survey

Such an anomalous looking feature will be investigated to see if it is harbouring significant amounts of economic minerals.
