The sixth chromite seam in the Lower Group (LG6) is an important source of chromite ore and is the ore body extracted at the mine. In the Eastern Lobe, in the vicinity of the mine, the strike is nearly north-south, with a dip of approximately 10 degrees towards the west. The average thickness of the LG6 seam is about 1.86 metres in the mine area.

The area influenced by any given hole is found as follows: (1) Divide angle at hole by 180°. (2) Multiply total area of entire prism by above result. (3) Multiply area found by (2) by the average thickness (found by solution of the formula) of ore in the hole, which thus transforms this smaller prism into volume.

Ferrovanadium is available in alloys containing 40%, 60% or 80% vanadium. The 60% and 80% grades are mostly produced by the aluminothermic reduction of vanadium oxides in the presence of steel scrap or by direct reduction in an electric furnace. The 40% grade is produced from slag and other vanadium products by the silicon reduction process.
