Summary:

Impala Rustenburg explores and mines the Merensky and UG2 Reefs, which are separated by a sequence of primarily anorthositic and noritic layered units, ranging from 45m in the northern part of the mining right area and thickening to 125m in the south.

The Merensky Reef is generally composed of an upper feldspathic pyroxenite, overlying a thin basal chromitite stringer, followed by an anorthosite to norite footwall. Locally, this is termed a ‘pyroxenite reef’. In some areas a pegmatoidal pyroxenite and a second chromitite stringer may be developed between the feldspathic pyroxenite and the footwall units. Locally this pegmatoidal pyroxenite can exceed 2m in thickness. This is termed a ‘pegmatoid reef’.

The UG2 Reef is defined as the main chromitite layer, with most PGM and base metal mineralisation confined to this unit, with a poorly mineralised pegmatoidal pyroxenite footwall. The main chromitite layer’s hangingwall is a feldspathic pyroxenite containing up to four thin and poorly mineralised chromitite layers. The vertical grade distribution is depicted in the accompanying graphs, showing peak values at reef contacts associated with chromitite. The average 6E ratios show the differences between the Merensky and UG2 Reefs, particularly the higher platinum to palladium ratio in the Merensky Reef and the relatively high proportion of rhodium in the UG2 Reef.

Both mineralised horizons dip gently away from the sub-outcrop in a north-easterly direction at 10° to 12°. The reefs may be disrupted by minor and major faults, lamprophyre, syenite and dolerite dykes, late- stage ultramafic replacement pegmatoid bodies and potholes. The potholes are generally circular and represent ‘erosion’ of, or slumping into the footwall units. They vary from a few metres to tens of metres across and up to tens of metres in depth. These features are accounted for in the Mineral Resource and Mineral Reserve estimates as geological losses, contributing to dilution or absence of the mineralised horizons.
