Reserves & resources

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
