The project contains 5.5 km strike length of mineralised gabbro. The mineralised gabbro generally outcrops as low ironstone ridges within the project area.  A typical cross-section through the Gabanintha deposit is shown below shows the basal “massive” magnetite unit which is overlain by a series of lower grade disseminated bands.


The long section below shows the weathering profile over the northern portion of the Gabanintha deposit. The weathering profile varies with the base of complete oxidation (BOCO) and the top of fresh (TOFR) being shallower in the north (left hand side).


The weathering of the basal massive unit has a direct impact on the recoveries of vanadium. The vanadium at Gabanintha is associated with magnetite which is magnetic, hence the first step in processing is magnetic separation. Oxidised magnetite is weakly to non-magnetic and cannot be separated from the gangue minerals (silica, alumina) efficiently. 

Areas where the transition and fresh zones are close to surface are obvious targets for initial production.
