Key production metrics from own operations for H1 F2025 compared to H1 F2024 are as follows: H1 F2025 H1 F2024 PGM production oz 4E oz 4E % variance Equivalent refined metal production from own operations at Zondereinde 165 076 160 188 3.1 Concentrate production from own operations at Booysendal 256 759 250 004 2.7 Concentrate production from own operations at Eland 37 488 32 574 15.1 Total equivalent refined metal production from own operations 451 213 434 977 3.7 Chrome concentrate production tonnes tonnes % variance Production at Zondereinde 242 402 229 679 5.5 Production at Booysendal 358 833 382 867 (6.3) Production at Eland 115 387 54 146 113.1 Total production 716 622 666 692 7.5 Equivalent refined PGM from third parties was 59 743 oz 4E (H1 F2024: 83 107 oz 4E), a decline to be expected given the current PGM sector dynamics. The group continues to grow PGM production from own operations towards our strategic goal of one million 4E ounces per annum, whilst preferentially targeting mechanised mining from quality UG2 orebodies, and concurrently reducing our overall risk profile through operational, geographical, metallurgical and revenue diversification. Our focus on mining of UG2 ore has also yielded substantial value through sales of chrome concentrate. This strategy continues to reinforce our position at the lower end of the sector cost curve and, importantly, also doing so on a positive risk-adjusted basis, thereby ensuring the sustainability of our long-life, quality assets. PGM production from Zondereinde remains on target, despite a stoppage during November as a result of a failure of a primary Eskom feed substation. Chrome concentrate production has benefitted from increased UG2 milling and further incremental improvements in chrome recovery. The commissioning of 3 shaft, where development and equipping continues, will positively impact production and efficiencies at Zondereinde over the medium to long-term. Above target PGM production from Booysendal once again demonstrates the intrinsic quality of this operation and Northam's continued efficient unlocking of the orebody's inherent long-term potential. Preferential milling of Merensky ore, a singular intervention to reduce stockpiles that were built up over time, has temporarily reduced production of chrome concentrate at Booysendal. The ramp-up of Eland continues but was marred by two tragic fatal accidents, the first involving a barring incident which occurred during shotcreting operations in a development tunnel, and the second related to a conveyor belt engineering incident occurring during a maintenance procedure. In spite of these events and the resultant stoppages, stoping production remains on target, with an increase in run of mine UG2 ore milled. This, together with upgrades to both the PGM and chrome concentrators, led to improved recoveries and consequently higher production of PGM and chrome concentrate. Our full year production guidance in respect of own operations remains unchanged, notwithstanding volatile and challenging market conditions impacting the entire PGM sector.
