Valterra Platinum is poised to embark on a transformative phase at its Mogalakwena mine, transitioning towards underground operations. This strategic move, set to commence with trial mining by late 2026, represents a proactive response to the evolving challenges within the platinum group metals (PGM) industry, particularly the natural depletion of high-grade ore from traditional open-pit methods. By delving deeper into the earth, Valterra aims not only to sustain but potentially enhance its PGM output, ensuring its continued prominence in the global market. This undertaking is a testament to the company's long-term vision, adapting to geological realities while striving for increased efficiency and production volume.
Valterra Platinum Commences Pivotal Underground Mining Trials at Mogalakwena
In a significant announcement, Valterra Platinum is set to begin underground trial mining at its expansive Mogalakwena mine in South Africa's Limpopo province by the close of 2026. This development was shared by project general managers during a recent media tour, highlighting a crucial shift for what is globally recognized as the largest open-pit PGM operation. The move is strategically targeted at the Sandsloot pit, renowned for its superior ore grades, signaling a calculated effort to counteract the natural decline in ore quality from the existing five open pits.
Platinum miners in South Africa have increasingly faced the necessity of deeper excavation to sustain production volumes, a practice that inherently escalates operational costs and risks. Mogalakwena, a cornerstone asset for Valterra, currently contributes nearly half of the company's total PGM production. To navigate this complex terrain, Valterra initiated a comprehensive feasibility study for the underground project in July, with an anticipated completion and investment decision slated for the first half of 2027.
Stephan Nothnagel, the general manager for Mogalakwena's underground mining studies, articulated the ambitious timeline, envisioning initial ore extraction and a potential ramp-up to a substantial 3.6–4.5 million tonnes per annum operation beyond 2030. This expansion is projected to significantly bolster Mogalakwena's concentrate production, with an expected increase of 10–50%. Concurrently, executives Martin Poggiolini and Agit Singh emphasized the company's dual focus: strengthening existing market demand and exploring avenues for new demand creation.
This strategic pivot follows Anglo American's decision in June to complete the demerger of approximately 51% of its stake in Valterra Platinum, an action approved by shareholders. Anglo American will maintain a 19.9% interest, which it intends to responsibly manage towards a complete separation over time.
From a journalist's perspective, Valterra Platinum's decision to venture into underground mining at Mogalakwena underscores a fascinating paradigm shift within the mature mining industry. It highlights the delicate balance between maximizing resource extraction and adapting to geological constraints and economic realities. This move is not merely about extending the mine's lifespan but represents an innovative embrace of deeper, more complex extraction methods to secure the future of platinum production. It also speaks to the resilience and forward-thinking nature of companies operating in a sector perpetually challenged by diminishing accessible resources. The success of this underground endeavor could serve as a blueprint for other established mines facing similar challenges, illustrating how strategic investments in advanced mining techniques can unlock significant untapped potential and ensure sustained profitability in an ever-evolving global market. Moreover, the focus on expanding demand for PGMs signals a broader industry effort to innovate not just in supply, but also in market development.
