Highlights

  • Copper equivalent production rose 13% YoY in Q2 and 6% for H1 2025, driven by higher copper output and Arcadium integration.

  • Pilbara iron ore production hit highest Q2 levels since 2018, rebounding from Q1 weather disruptions.

  • Simandou project accelerated, with first shipment now expected in November 2025.

Rio Tinto (ASX:RIO) has released operational performance numbers for the second quarter of 2025, highlighted by a 13% year-on-year increase in copper equivalent (CuEq) production. The encouraging result reflects improvements across copper, iron ore, and bauxite segments, along with the impact of the Arcadium acquisition.

Chief Executive Jakob Stausholm attributed the results to operational efficiency and project execution, noting, “We delivered excellent operational performance from our mine operations with record production from our bauxite business and from Oyu Tolgoi.” He added that the company remains focused on driving long-term profitable growth while building a more diversified business.

Copper and Bauxite Drive Quarterly Growth

Copper production has exceeded expectations, positioning the company at the upper end of its full-year copper guidance. The ramp-up at Oyu Tolgoi underground mine, combined with output from Escondida, contributed to this growth. Additionally, copper unit costs are now projected near the lower end of guidance due to effective cost control and higher-than-expected gold prices.

Bauxite production also reached a new quarterly record, the second in a row, and is now tracking toward the higher end of full-year guidance. 

Iron Ore Recovers; Simandou Timeline Accelerated

Despite disruptions from four cyclones in Q1, Pilbara iron ore operations recorded their highest Q2 production since 2018, signaling a full recovery. However, full-year Pilbara shipments are still expected at the lower end of guidance, subject to heritage and regulatory approvals.

In a key development, Rio Tinto announced that first shipments from its Simandou iron ore project in Guinea are now expected around November 2025, ahead of previous timelines. The company expects to ship between 0.5 and 1.0 million tonnes this year under its SimFer joint venture, marking an important milestone for the high-grade iron ore asset.

Production and Cost Guidance Maintained

Rio Tinto has maintained its 2025 production and unit cost guidance, with no changes from previous forecasts:

  • Pilbara iron ore: Lower-end of shipment guidance due to Q1 cyclones.

  • Copper: Higher-end of production guidance; lower-end of cost guidance.

  • Bauxite: Higher-end of production guidance.

  • Titanium dioxide slag: Lower-end of production guidance due to weaker market demand.

The company noted that cost performance in Pilbara iron ore benefited from a weaker Australian dollar in the first half of 2025.

Rio Tinto also confirmed that its Western Range iron ore development was completed on time and on budget, while the Hope Downs 2 project received all necessary government approvals in Q2.

Executive Appointment and Market Reaction

Rio Tinto announced the appointment of Simon Trott as Chief Executive, effective 25 August 2025, as part of its long-term leadership succession planning.
