Snapshot	The Mogale Tailings Retreatment project (MTR project) consists of the Mogale Cluster tailings storage facilities (TSFs) and the Soweto Cluster TSFs(MSC). The Company completed a definitive feasibility study on the Mogale Gold TSFs and announced the results of this study on 30 June 2022 (the study). The study demonstrated compelling economics and the potential to significantly increase the Group’s gold production (an increase in excess of 25% compared to current Group annual production) over an initial life-of-mine of 13 years. Remining of the MSC TSFs has the potential to add further production upside and extend the life-of-mine to 21 years.

• Tailings

Summary:

The ore that will be treated at the MTR plant originated from the previously mined and metallurgically treated Kimberley, Bird, Livingstone, South and Main Reefs from historical gold mining operations of WRCM, Luipaardsvlei Gold Mine, Rand Leases and DRD Gold. The reefs are arenaceous conglomeratic sedimentary rocks of the Archaean age and are generally considered as ancient river placers. These reefs are frequently less than a metre thick and characterised by abundant pyrite, which may comprise up to 5% of the reef, as well as flyspeck and/or seam carbon/kerogen. These three components display a strong spatial correlation with the gold mineralisation, which is rarely visible, in the 10 to 20 micron range.

The tailings of the treated material were deposited onto various TSFs on surface that will be reclaimed over the modelled life of the operation. Once re-treated, the final tailings emanating from these TSFs will be consolidated into a modern tailings facility, through the filling of legacy opencast mines and the construction of an enlarged modern facility on the 1L23-25 footprint. This will reduce the MTR plant’s environmental footprint and associated environmental impact.
