A key feature for F2023 has been the strong production performance and contribution from all our operations. Key production metrics for F2023 compared to F2022 are as follows: F2023 F2022 oz 4E oz 4E % variance Equivalent refined production from own operations at Zondereinde 321 901 321 962 (0.0%) Concentrate production from own operations at Booysendal 452 903 372 623 21.5% Concentrate production from own operations at Eland 48 800 33 086 47.5% Total equivalent refined metal production from own operations 809 775 716 488 13.0% Equivalent refined metal purchased from third parties 120 407 61 961 94.3% Total equivalent refined metal production from own operations 930 182 778 449 19.5% including refined metal purchased from third parties Significant production growth has been achieved during F2023 as a result of focussed execution of the group’s growth strategy, which continues to deliver against set targets. Challenges remain, particularly in respect of high mining inflation and the potential for further and possibly more severe Eskom load curtailment events. However, our growth and operational diversification programmes remain on-track and continue to demonstrate the value of our counter cyclical investments and execution capacity across the group, as well as our flexibility in dealing with these challenges.
