Highlights as at December 31, 2020

  • A 40% increase in 4E Platinum group metals (PGM) Mineral Reserves at the SA PGM operations to 39.5M 4Eoz, primarily due to the inclusion of the Marikana K4 project (12.7 M 4Eoz) and the Klipfontein opencast project (0.1M 4Eoz) following detailed feasibility studies.
  • A 7% (5.8Moz) increase in 2E PGM Mineral Resources, with additional Mineral Reserves of 0.8M 2E PGM ounces defined at East Boulder Mine replacing combined depletion of 0.7M 2Eoz during 2020.  Combined stable Mineral Reserves of 26.9M 2Eoz at the US PGM operations.
  • Stable Mineral Reserves of 11.3Moz at the SA gold operations, with depletion of 1.0 Moz for 2020 off-set by
    • an 0.8Moz increase in attributable Mineral Reserves from DRDGOLD due to the increase in Sibanye-Stillwater’s shareholding in DRDGOLD from 38.05 to 50.1%,
    • an additional 0.2Moz Mineral Reserves derived from secondary reef exploration programmes at the Driefontein operation.
  • Mineral Resources at the SA gold operations decreased by 15.9Moz, primarily due to the exclusion of Below Infrastructure Mineral Resources at Driefontein
  • The declared Mineral Resources and Mineral Reserves for our managed operations and projects are the outcome of a detailed annual operational and life of mine (LoM) planning process and are indicative of the considerable underlying mineral assets base which supports sustainable and robust long-life production.
