Summary:

At Inata, mineralisation occurs within a well-defined shear zone marking the boundary between the granitic and volcanic rocks of the Damba-Inata Domain in the west and the Sona Sedimentary Basin in the east. Gold mineralisation occurs within a sub-vertical shear zone that cuts along folded carbonaceous shales that are sandwiched between sedimentary and volcanic rocks. Quartz-feldspar porphyry dykes intrude along the shear zone and are contemporaneous with the later stages of gold mineralisation. Gold mineralisation is always linked to quartz veins (boudinaged, folded or brecciated quartz veins) or disseminated in haematitic alteration haloes around quartz-carbonate-albite veins.

The Inata gold deposit is deeply weathered with the base of complete oxidation extending down to depths of 60m. A transitional zone of moderate oxidation extends down to more than 150m depth.
