Karari - Dervish is a structurally complex deposit and is bound by several post mineralisation faults. The principal fault that offsets Karari from Dervish in the Osman Fault. Mineralisation is principally hosted in volcanoclatic sandstones and to a lesser extent intermediate intrusives. Gold is strongly associated with albite, K-Feldspar, silica, haematite, carbonate and pyrite alteration. Mineralisation is dominated by two key orientations; (i) sub-parallel to lithological contacts, striking NNW and dipping moderately to the NE, and (ii) a WNW striking and shallowly NE dipping with a northerly plunge.

A recent 3D seismic survey was completed over the deposit to assist in unlocking further endowment from the system, which has already delivered significant growth.
