Company Overview & Strategic Evolution: Sibanye Stillwater Limited

Sibanye Stillwater Limited emerged from the strategic merger of Sibanye Gold—a stalwart in South African gold mining—and the US-based Stillwater Mining Company. This merger forged a global mining entity with deep roots in both the southern hemisphere and North America. Today, the company boasts a diversified portfolio that extends across South Africa, the United States, and new investments in rare earth element (REE) assets.

• Global Reach: Extensive mining operations in South Africa (gold, PGMs) and Montana, USA (PGMs, rare earths).
• Core Sectors: Gold, platinum, palladium, and rare earth elements—vital for a wide spectrum of current and emerging technologies.
• Strategic Pivot: In 2025, the company sharply pivoted towards sustainable mining and critical mineral production, aligning with the world’s accelerating demand for green energy and advanced manufacturing.
• Geographical Diversification: Deploying resources across two continents to reduce geopolitical risks and strengthen supply chain resilience.

This evolution not only secures Sibanye Stillwater Limited’s relevance in traditional and emerging mineral sectors, but also positions the company at the forefront of responsible resource development.

Flagship Operations: Mining Gold, PGMs & Rare Earths in South Africa and the USA

At the heart of Sibanye Stillwater operations are several flagship mines, each contributing to both local economies and the global supply of critical minerals:

South Africa: Gold and PGMs (Platinum Group Metals)

• Gold Operations: Massive gold mines across the South African gold belt contribute substantially to the region’s economy and employment.
• PGMs: South Africa remains one of the world’s largest producers of platinum and palladium, elements that are indispensable for the automotive and industrial manufacturing sectors, especially in catalytic converters for emissions reduction.
• Social & Economic Impact: These mines engage thousands of workers, generate crucial infrastructure improvements, and anchor wider community development initiatives.

Montana, USA: Stillwater – The American Anchor for PGMs & Rare Earths

• Stillwater Operations: One of the only significant primary sources of platinum and palladium in the United States, supporting American industry and supply chain independence.
• Rare Earths (REE): The recent establishment of the Stillwater Rare Earth division places Montana at the center of the USA’s rare earths supply, with deposits critical for the green energy transition, high-tech manufacturing, and defense sectors.
• Technological Advancements: The Montana assets are testing grounds for advanced extraction methods and environmental best practices setting new industry standards for sustainability.

“Stillwater’s operations supply nearly 5% of the U.S. rare earth metals crucial for sustainable technology production.”

Stillwater Rare Earth: Focus on Critical Minerals for Green Technology

A key highlight for 2025 has been Sibanye Stillwater’s intensified focus on rare earth elements through its Stillwater Rare Earth division. In an era when advanced electronics, renewable energy systems, and national defense applications hinge on the secure supply of rare earths, the company’s commitment positions it as a pioneering force in the sector.

Why Are Rare Earth Elements (REEs) So Important?

• Vital Components: Elements such as neodymium, praseodymium, and dysprosium are fundamental in making permanent magnets for wind turbines, electric vehicles (EVs) motors, and various electronics—from smartphones to satellites.
• Defense and Advanced Manufacturing: Rare earths are indispensable for the U.S. defence sector and emerging energy technologies.
• Supply Chain Security: U.S.-based production reduces overreliance on unstable international sources and enhances national resource security.

Optimized, Sustainable Extraction Methods

The Stillwater Rare Earth division employs optimized extraction techniques designed to minimize environmental impact and enhance recovery rates. This approach ensures the delivery of critical elements with a significantly lower environmental footprint than industry norms, setting a valuable benchmark for others to follow.

Sustainable Mining: Sibanye Stillwater’s Environmental Innovations

As market and regulatory expectations in 2026 and beyond demand greater responsibility, Sibanye Stillwater Limited continues to emphasize sustainability in every aspect of its mining operations. This shift is not only about compliance—it’s a strategic pivot towards ensuring environmental and social license to operate.

• Comprehensive ESG Framework: The company’s ESG framework is integrated across all sites, governing safety, resource use, and community engagement.
• Cutting-edge Technologies: Adoption of remote sensing, automation, and water recycling systems for cleaner and more efficient extraction and processing of minerals.
