Wedoany.com Report-Aug. 30, Valterra Platinum has outlined plans to begin trial mining at its Mogalakwena operation in Limpopo province, South Africa, by late 2026. The mine, located north of Johannesburg, is widely regarded as the world’s largest open-pit platinum group metals (PGM) mine. The announcement was made by project leadership during a recent media visit.

Valterra hopes that the underground mine will contribute to a 10–50% increase in Mogalakwena concentrate production.

Mogalakwena currently comprises five open pits, with the Sandsloot pit identified for underground development due to its higher ore grades. South Africa’s platinum sector has been increasingly moving underground to sustain production as surface ore grades decline, a shift that brings both higher costs and operational challenges. Mogalakwena remains a core asset for Valterra, contributing nearly half of the company’s total PGM production.

The company began a feasibility study for the underground expansion in July 2025, with completion expected in the first half of 2027. Based on the study’s findings, an investment decision will be made. Stephan Nothnagel, general manager of Mogalakwena underground mining studies, said: “We are also envisioning a trial mining… in the back end of 2026.” He further indicated that initial extraction could pave the way for a potential ramp-up to a 3.6–4.5 million tonnes per annum (mtpa) operation beyond 2030.

If successful, the underground development is expected to support a 10–50% increase in Mogalakwena concentrate output. This expansion is seen as an important step for Valterra to maintain its production profile and secure long-term supply from its most significant mine. Executives Martin Poggiolini and Agit Singh emphasized that the company is not only focused on increasing production but also on scaling up demand in current markets while working to establish new demand segments.

In a separate update, Anglo American finalized the demerger of approximately 51% of its stake in Valterra Platinum in June 2025, following approval from shareholders. After the restructuring, Anglo American now retains a 19.9% holding in Valterra, which it intends to manage responsibly as part of a process to achieve full separation over time.

The Mogalakwena underground project marks a key phase in Valterra’s strategy to adapt to changing ore conditions, manage operational costs, and enhance long-term output. With trial mining expected in late 2026 and full feasibility results due in 2027, the project has the potential to reshape the company’s production base and extend the future of one of its most valuable assets.
