Rio Tinto Q2 Production: Copper Cost Guidance Slashed, Kennecott Outage, Lithium Ahead of Plan

summarizeSummary

Rio Tinto's Q2 production update featured 3% H1 copper equivalent growth, a sharp reduction in copper cost guidance, and early lithium production, but a Kennecott smelter outage and large working capital outflow temper the outlook.

• Copper Cost Guidance Slashed

  Copper C1 net unit cost guidance has been reduced to US 30-50c/lb from US 65-75c/lb, driven by higher gold prices and productivity gains.

• Kennecott Smelter Outage

  A flash converting furnace breach in June will require a 75-day rebuild, reducing refined copper and gold output in H2 2026, though total copper production estimates are unchanged.

• Lithium Projects Ahead of Plan

  First production achieved at Sal de Vida and Fénix 1B ahead of schedule; Q2 lithium carbonate equivalent production rose 20% YoY.

• Oyu Tolgoi Tax Dispute

  Oyu Tolgoi paid $443 million in disputed Mongolian tax assessments in March 2026; Rio Tinto is in discussions with the government to resolve the matter.

A mixed Q2 production report from Rio Tinto reveals both operational momentum and emerging headwinds. While copper equivalent production grew 3% in the first half—powered by a 31% surge at Oyu Tolgoi—total copper output fell 7% in Q2 after a furnace outage at Kennecott, which will continue to weigh on refined metal in the second half. In a significant positive, the company more than halved its copper cost guidance. Lithium projects also reached first production ahead of schedule. However, a $443 million Mongolian tax payment and a $1.2 billion working capital drain raise cash flow concerns, offering a comprehensive look at the portfolio's shifting dynamics.
