The UG2 Reef is defined as a main chromitite layer, with most of the mineralisation contained within this unit, followed by a poorly mineralisedpegmatoidalpyroxenite footwall.
Impala holds contiguous mining rights and prospecting rights for a total area of 33 191ha across 20 farms or portions thereof. The prospecting area involving the joint venture with Royal Bafokeng Resources Platinum (Pty) Ltd (RBR) has this year for the first time been factored into the Mineral esource estimate. Agreement has been reached in priciple with a third party to transfer a portion of the Mineral Resources in the southern extremity on the so-called Fourth and fifth Bagokeng Area pending regulatory approvals. The corresponding mineral Resources have been excluded from the 2010 statement.
Both the Merensky and UG2 Reefs are being exploited; the bulk of the mining at Impala is conventional breast mining. Mechanisedbord and pillar mining takes place in selected areas only, while limited open pit mining takes place at the outcrop position.
