OUR VISION

Superior value creation for all of our stakeholders through responsible mining and beneficiation of our mineral resources.

Our structure

Southern Africa

In South Africa, our gold producing assets and projects are located throughout the Witwatersrand Basin and our PGM assets are on the southern portion of the western limb of the Bushveld Complex, near Rustenburg. Mimosa, in the south of the Great Dyke in Zimbabwe, is a PGM-joint venture with Impala Platinum Holdings Limited (Implats).

Southern Africa


United States

Our PGM-producing assets are located in a geological formation, the J-M Reef, in south-central Montana. The J-M Reef, the only known significant source of PGMs in the United States, is the highest-grade PGM deposit known in the world.

OUR PRODUCTS

Gold

In our SA region, Sibanye-Stillwater mines, extracts and processes gold-bearing ore to produce a beneficiated product, doré, which is then refined further at Rand Refinery Proprietary Limited (Rand Refinery) 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 33% interest in Rand Refinery, one of the largest global refiners of gold, and the largest in Africa, which then markets and sells the 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), for jewellery and for various industrial purposes.

Platinum group metals

At our PGM operations in South Africa and Zimbabwe, the primary PGMs produced are platinum, palladium and rhodium, which together with the gold occurring as a coproduct, are referred to as 4E (3PGM+Au), by ratio 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-inconcentrate, which is currently processed further by third parties.

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

The major sources of demand for PGMs are for autocatalytic convertors and jewellery. Together, these two areas account for around 72% of platinum demand while, for palladium, autocatalytic convertors account for 80% of demand for that metal.*

By-products

At our PGM operations, 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.
