 Bauxite production of 58.7 million tonnes was 7% higher than 2023, exceeding our guidance. We delivered record annual production at Gove and Amrun following implementation of the Safe Production System. We shipped 40.9 million tonnes of bauxite to third parties, 10% higher than 2023. Segmental revenue for bauxite increased 28% to $3.1 billion . This includes freight revenue of $0.5 billion (2023: $0.5 billion). Alumina production of 7.3 million tonnes was 3% lower than 2023, due to the impacts to our Gladstone operations from the breakage of the third-party operated Queensland Gas Pipeline in March. Gas supplies to our Gladstone operations from the third-party operated Queensland Gas Pipeline were meeting 100% of our requirements by year- end. As the result of sanction measures by the Australian Government, Rio Tinto has taken on 100% of capacity of Queensland Alumina Limited (QAL) for as long as the sanctions continue. This results in use of Rusal’s 20% share of capacity by Rio Tinto under the tolling arrangement with QAL. This additional output is excluded from the production tables in this report as QAL remains 80% owned by Rio Tinto and 20% owned by Rusal. Aluminium production of 3.3 million tonnes was 1% higher than 2023. At our New Zealand Aluminium Smelter (NZAS), production continued to ramp up following a previous call from Meridian Energy to reduce electricity usage in August 2024, for which we are compensated. As previously reported, we expect the ramp-up to run through to the second quarter of 2025. We completed the previously announced acquisition of Sumitomo Chemical Company’s (SCC’s) 20.64% interest in NZAS on 1 November 2024 and now fully own the Tiwai Point aluminium smelter. We also completed the previously announced acquisition of SCC’s 2.46% stake in Boyne Smelters Limited (BSL). The completion of this transaction, along with the recently completed acquisition of Mitsubishi’s 11.65% stake in BSL, brings Rio Tinto’s total interest in BSL to 73.5%. Production is reported including these changes in ownership from 1 November 2024.
