Valterra Platinum CEO Craig Miller rode down into the Mogalakwena open pit inside a Komatsu 930 haul truck, using the company’s annual safety day to signal a shift in culture. The visit put a human face on an aggressive operational overhaul reshaping the world’s top platinum supplier.

Miller spent the shift with driver Dikeledi, discussing daily site hazards, personal accountability, and steps toward eliminating workplace injuries across all operating tiers. The chief executive said safety remains deeply personal, adding that operational procedures must protect the families and futures of workers across pits, processing plants, and administrative offices.

Rebuilding value outside Anglo

The grassroots engagement comes alongside a sharp earnings turnaround during Valterra’s first full financial stretch separated from former parent Anglo American. Miller took the helm in October 2023, subsequently navigating the miner through its May 31, 2025, demerger to secure dual listings in both Johannesburg and London.

Net profit climbed sharply to R15.81 billion ($962.8 million) from R7.39 billion ($450 million), boosted by firm realized commodity pricing across primary offshore markets. Adjusted EBITDA leaped 68 percent to R33.37 billion ($2.03 billion), while overall revenue rose 6.7 percent to touch R116.33 billion ($7.08 billion).

An 89 percent rally in dollar basket prices for platinum group metals widened operating margins, shielding the miner from broader industrial inflation. Strict cost controls and insurance payouts from previous site disruptions protected the balance sheet, while sustained demand from automotive and manufacturing clients in Europe and Asia kept physical shipments steady.

Taking the dig underground

Valterra is now leveraging western supply security worries to position South Africa as a vital supplier of critical industrial minerals. Management contends geopolitical fissures hand local exporters a clear advantage, provided regional logistics lines and port infrastructure hold steady enough to support long-term private capital projects across the country.

Mogalakwena remains the engine room of that broader commercial ambition, generating nearly half of group output. The open-pit asset delivers between 900,000 and 1,000,000 ounces each year at bottom-tier cash costs. Yet deepening surface pits eventually squeeze margins, forcing engineers to plot smarter, lower-cost access routes to deeper deposits.

Planning now centers on transitioning operations at the adjacent Sandsloot deposit underground, targeting higher-grade ore bodies to curb extraction costs. The underground model drastically cuts surface tailings, operating at a 2-to-1 waste ratio versus open-cast ranges of up to 10-to-1, saving massive volumes of heavy transport fuel.

Squeezing costs through tech

Efficiency gains are running directly through downstream concentrator circuits as well. Valterra installed Jameson flotation cells at the site, marking an industry first for platinum processing. The high-intensity technology cuts concentrate volume, drives down electricity demands during subsequent smelting cycles, and removes haulage trucks from congested local road routes.
