Name of the Project
Mponeng extension and deepening project.

Location
West Wits region, South Africa.

Project Owner/s
Harmony Gold Mining Company.

Project Description
Mponeng is a world-class mine with two excellent, well-defined orebodies – the Carbon Leader reef (CLR) and Ventersdorp Contact reef (VCR) – with average face grades of more than 14 g/t and recovered grades of more than 9 g/t.

The project will access the VCR and CLR orebodies below existing infrastructure. This will be achieved through the selective extraction of the high-grade VCR areas to the east and west, through independent accesses, while eliminating the requirement to mine the lower-grade fretted terrace in the geographical centre of the orebody. 

The CLR at the TauTona shaft pillar will also be mined, accessing this through the 75 Level at Mponeng. 

The project extends the life of Mponeng to 20 years and adds 2.34-million ounces in mineral reserves.
