Rio Tinto announced on 14 October 2025 that it achieved record bauxite production and expects over 50% output growth at its Oyu Tolgoi copper mine this year, signaling strong performance in its key mining operations.

However, the company cautioned that it may miss its 2025 Pilbara iron-ore shipment target due to scheduled maintenance, with Q3 shipments showing signs of weakness. Despite these concerns, Rio Tinto’s stock rose 2.3% in Sydney, closing at A$128.12.

On a positive note, Rio Tinto lowered its 2025 copper unit cost guidance to US$1.10–US$1.30 per pound, down from the previous US$1.30–US$1.50 range, benefiting from rising gold prices associated with its copper mining operations.

The combination of record bauxite output, improved copper cost efficiency, and strategic production guidance positions Rio Tinto to navigate operational challenges while sustaining growth across its diversified mining portfolio.
