Highlights as at December 31, 2019

  • 90% increase in the total Platinum Group Metals (PGM) Mineral Resources to 389.0Moz and a 20% increase in the Group’s PGM Mineral Reserves to 55.1Moz, primarily due to the inclusion of the Marikana (previously Lonmin) assets, acquired in June 2019
  • Ongoing successful definition drilling at the Blitz project, Stillwater Mine, at the United States (US) PGM operations yielded 2.0Moz of additional Mineral Reserves
  • Gold Mineral Resources at the South African (SA) gold operations increased by 52% primarily due to a reduction in costs associated with the Kloof integration project, facilitating a decrease in cut-off grades
  • Exploration projects’ advanced through the establishment of key partnerships including Aldebaran Resources Inc, Generation Mining Ltd and Wallbridge Ltd
