Group profile

Sibanye-Stillwater is an independent, global, precious metals mining company producing a unique mix of metals that includes platinum group metals (PGMs) and gold.

Globally, Sibanye-Stillwater is the largest primary producer of platinum* and the second-largest palladium* producer. It is also the second-largest producer of gold from South Africa.

* Including proforma of the Lonmin transaction

Domiciled and with its head office in South Africa, Sibanye-Stillwater owns and operates a portfolio of high-quality global operations, processing facilities and projects made up as follows:

United States (US) PGM operations

The East Boulder and the Stillwater (including Blitz) mines are located in Montana, in the United States. The Columbus Metallurgical Complex, which smelts the material mined to produce PGM-rich filter cake, also recycles PGMs from autocatalysts.

Southern Africa (SA) PGM operations

The Kroondal, Rustenburg and Platinum Mile operations are located on the western limb of the Bushveld Complex in South Africa, while the Mimosa joint venture is situated on the southern portion of the Great Dyke in Zimbabwe. Platinum Mile is a retreatment facility, which reprocesses arisings from Rustenburg.

South Africa (SA) gold operations

The Driefontein, Kloof and Cooke surface operations and associated processing facilities are located on the West Rand of the Witwatersrand Basin, while Beatrix is in the southern Free State goldfields. Sibanye- Stillwater also has an interest in surface tailings retreatment facilities located from the East Rand to the West Rand through our 38.05% stake in DRDGOLD Limited (DRDGOLD).


Our projects include:

  • The Marathon PGM project in Ontario, Canada
  • The Altar and Rio Grande copper-gold projects in the Andes in north-west Argentina, close to the Chilean border
  • The Hoedspruit, Zondernaam and Vygenhoek, PGM projects in South Africa
  • The Burnstone and the southern Free State gold projects in South Africa

Operating framework

Our operating framework is underpinned by strong, ethical corporate governance that is based on the principles of accountability, transparency, competence, responsibility, fairness and integrity, which are fundamental to the long-term sustainability of our business and to sustained value creation for all stakeholders. These principles, which are implicit in and integral to our CARES values, are applied in the management of our business and in engaging with and reporting to shareholders and other stakeholders. Our governance structures, processes and policies, together with our code of ethics, underpin execution of our strategy and support our business model.


Platinum group metals

At our PGM operations in South Africa and Zimbabwe, the primary PGMs produced are platinum, palladium and rhodium, which together with gold, are referred to as 4E (3PGM+Au). Production by ratio is approximately 58% platinum (Pt), 32% palladium (Pd), 8% rhodium (Rh) and 2% gold (Au). The PGM-bearing ore mined here is processed to produce PGMs-in-concentrate, which is currently processed and refined by third parties.

The US PGM operations primarily produce palladium and platinum (78% palladium and 22% platinum), referred to as 2E (or 2PGM). The PGM-bearing ore mined is processed and smelted to produce a PGM-rich filter cake. A third party refines the filter cake to produce refined PGMs.

The major sources of demand for PGMs are for use in autocatalysts and jewellery. Combined, these two areas accounted for around 69%* of gross platinum and palladium demand in 2018. Autocatalysts alone accounted for 40%* of gross platinum demand and for 85%* of gross palladium demand in 2018.

Sibanye-Stillwater mines, extracts and processes gold-bearing ore at its SA gold operations to produce a beneficiated product, doré, which is then refined at Rand Refinery Proprietary Limited into gold bars with a purity of at least 99.5% in accordance with the London Bullion Market Association’s standards of Good Delivery. Sibanye-Stillwater holds a 44% interest in Rand Refinery, one of the largest refiners of gold globally, and the largest in Africa. Rand Refinery markets and sells refined gold on international markets to customers around the world.

The main sources of demand for gold are as a store of value (such as central bank holdings), as an investment (exchange traded funds, bars and coins), jewellery and for various industrial purposes.


At our PGM operations in both regions, the minor PGMs – iridium and ruthenium – are produced as co-products. They, together with the three primary PGMs, are referred to as 6E (5PGM+Au).

In addition, at the SA PGM operations, nickel, copper and chrome, among other minerals, are produced as by-products.
