Rio Tinto reported strong fourth quarter and full-year 2025 operating results, highlighted by an 8% year-on-year increase in copper equivalent production and 5% higher shipments. Pilbara iron ore achieved record quarterly production and shipments in Q4, with full-year Pilbara shipments of 326.2 Mt on a 100% basis, only slightly below 2024 despite earlier cyclone disruption. Copper production on a consolidated basis rose 11% to 883 kt for 2025, driven by the ramp-up of Oyu Tolgoi, where underground development is now complete and delivering record quarterly output. Bauxite reached a record 62.4 Mt, up 6%, aluminium rose 3% to 3.38 Mt and lithium carbonate equivalent production was 57 kt, reflecting growth in Argentina operations. The company met or exceeded its 2025 production guidance across product groups and kept 2026 production guidance unchanged from prior disclosures, while exploration and evaluation expense fell to $795 million from $935 million in 2024.
