Ivanplats’ Platreef project in Limpopo is challenging conventional approaches to underground PGM mining.

Using its unusually thick orebody to support a highly mechanised, bulk-mining model. Richard Jansen van Vuuren travelled to Limpopo Province in South Africa to discuss the deeper aspects of this once-in-a-generation ore body with Shadrack Dedeka, MTS Manager: Mining (Ivanplats) and Maemo Moshakgomo, GM: Operations (Ivanplats).

Unlike many traditional South African PGM operations, which extract narrow reefs typically one to two metres thick, Platreef’s orebody exceeds 20 metres in thickness, with an average grade of approximately four grams per tonne. This geological advantage creates opportunities for larger-scale extraction, improved productivity and reduced reliance on labour-intensive conventional mining methods.

The operation is being developed around mechanisation and long-hole stoping, supported by a phased expansion strategy designed to increase production capacity as underground infrastructure develops.

Technology is central to this approach. Advanced infrastructure and VR operator training are intended to strengthen workforce readiness, support safer operating practices and improve efficiency in a complex underground environment.

As South Africa’s PGM industry faces pressure to improve productivity, manage costs and sustain competitiveness, Platreef offers an alternative model for exploiting thick, high-tonnage mineral deposits.

Its development highlights how geology, mechanisation and digital training can combine to reshape underground mining - potentially offering lessons for future PGM projects in South Africa and beyond.
