Century Zinc Operation

100%-owned zinc tailings retreatment (secondary mining) operation in Queensland, acquired on 22 February 2023, hydraulically re-mining and processing tailings from the historic Century open-pit mine. 2025 was a strong year, beating production and cost guidance: ore mined and processed rose to 8,210kt, payable zinc production increased 22% to 101kt and AISC improved 17% to US$1,921/tZn, driving adjusted EBITDA to US$88M (R1.6bn) on enhanced production stability, firmer zinc prices and lower treatment charges. The operation anchors the AUS zinc reserve and resource base (308kt and 963kt contained zinc) and forms part of the Group's circular-economy secondary mining portfolio.
