• Total reef tonnes milled for the quarter at 1 427.4 kt (Q4 FY2022: 1 446.8 kt), utilising stockpiles to maintain plant throughput
• Quarterly PGM production at 42.7 koz (Q4 FY2022: 45.3 koz)
• Rougher feed grade of 1.66 g/t (Q4 FY2022: 1.67 g/t)
• Recovery of 71.7% (Q4 FY2022: 76.2%) as oxidised ore from the stockpile was fed into the circuits
• Quarterly chrome production at 383.1 kt (Q4 FY2022: 416.2 kt)
• Grade of 17.0% Cr2O3 (Q4 FY2022: 17.3%)
• Recovery at 65.7% (Q4 FY2022: 69.6%) impacted by high variability of ore mix and feed grade, as well as work on spiral adjustment and replacement, impacting mainly specialty output with metallurgical chrome output up on a quarter-by-quarter basis
• Vulcan Plant optimisation continuing with increased output on track for H2 FY2023 Karo Platinum Update
• Construction commencement ceremony was held on 7 December 2022, with land clearing continuing
