Group profile

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

Domiciled in South Africa, Sibanye-Stillwater owns and operates a portfolio of high-quality operations and projects, which are grouped by region: the Southern Africa region and the United States region.

Globally, Sibanye-Stillwater is the third largest producer of palladium and platinum and features among the world’s top ten gold producing companies.

The PGM-bearing ore mined at Sibanye-Stillwater’s operations in South Africa and Zimbabwe in the Southern Africa region is processed to produce PGMs-in-concentrate. At operations in the United States region, the ore mined is processed, smelted and refined to produce a PGM-rich filter cake.

The primary PGMs produced at the Southern Africa operations are platinum, palladium and rhodium, which, together with the gold that occurs as a by-product, are referred to as 4E (3PGM+Au), by ratio approximately 58% Pt, 32% Pd, 8% Rh and 2% Au). At operations in the United States region, the PGMs produced are principally palladium and platinum (78% Pd and 22% Pt), which are referred to as 2E (2PGM).

OUR VISION

Superior value creation for all our stakeholders through mining our multi-commodity resources in a safe and healthy environment.

Our structure

Southern Africa

The Southern Africa region houses the gold and PGM operations and projects located in South Africa and Zimbabwe.

Our underground and surface gold mining operations in South Africa are the Cooke, Driefontein and Kloof operations in the West Witwatersrand (West Wits) region of Gauteng and the Beatrix operation in the southern Free State. Sibanye-Stillwater also owns and manages significant gold extraction and processing facilities where ore is treated and beneficiated to produce gold doré. In addition, several organic projects currently underway are aimed at sustaining these gold mining operations into the long term.

Our PGM assets in the Southern Africa region are Kroondal (50%), the Rustenburg Operations (100%) and the tailings retreatment entity, Platinum Mile (91.7%) in North West Province, South Africa, and Mimosa (50%) in Zimbabwe.

Southern Africa


United States

The United States region houses our PGM operations and projects located in the United States, Canada Argentina. These include the East Boulder and Stillwater mining operations and the Blitz project in Montana, in the United States, and two exploration-stage projects, Marathon, a PGM-copper porphyry in Ontario, Canada, and Altar, a copper-gold property in San Juan, Argentina.

Assets in this region also include the Columbus Metallurgical complex in Montana. This complex houses the concentrator and smelter facilities as well as a base metal refinery which produces a PGM-rich filter cake that is further refined by a third-party precious metal refinery. These processing and metallurgical facilities are also used to process recycled material such as spent autocatalytic convertors and petroleum refinery catalysts.

OUR PRODUCTS

Gold

In the Southern Africa region, Sibanye-Stillwater mines, extracts and processes gold-bearing ore to produce a beneficiated product, doré, which is then sent for further refining at Rand Refinery Proprietary Limited (Rand Refinery) which produces 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 refiners of gold globally, and the largest in Africa. Rand Refinery markets and sells the refined gold on international markets to customers around the world.

Platinum group metals

Sibanye-Stillwater mines PGM-bearing ore that is processed to produce PGMs-in-concentrate at its operations in the Southern Africa region and, in the United States region, the ore mined is processed, smelted and refined to produce a PGM-rich filter cake.

At operations in the Southern Africa region, the primary PGMs produced are platinum, palladium and rhodium, which, together with the gold that occurs as a co-product, are referred to as 4E (3PGM+Au).

At operations in the United States region, the PGMs produced are principally palladium and platinum, which are referred to as 2E (2PGM).

By-products

In the Southern Africa region, uranium ore is a by-product at certain of Sibanye-Stillwater’s gold operations. The underground ore is processed initially to recover the uranium and then reprocessed to extract the gold.

At our PGM operations in the Southern Africa region, the minor PGMs produced as co-products are iridium and ruthenium, which, together with the three primary PGMs, are referred to as 6E (5PGM+Au). In addition, nickel, copper and chrome, among other minerals, are produced as by-products.

At the PGM operations in the United States region, by-products include rhodium, gold, silver, copper and nickel.
