The production report is operationally mixed — strong iron ore and lithium growth offset by a copper miss at Kennecott and a material tax dispute in Mongolia. Monitor H1 2026 financial results for revenue and free cash flow impact from the working capital outflow and the Mongolian tax payment. The Kennecott smelter rebuild timeline (75 days) will pressure H2 copper output.

Executive Summary
Rio Tinto released its Q2 2026 production results, reporting a 3% YoY increase in copper equivalent (CuEq) production for H1 2026. Key highlights include record first-half iron ore production in the Pilbara, a 31% YoY increase in copper production at Oyu Tolgoi, and first production ahead of plan at the Sal de Vida and Fénix 1B lithium projects. However, total consolidated copper production fell 7% YoY in Q2 due to operational issues at Kennecott, and the company disclosed a $443 million tax dispute with Mongolia and a ~$1.2 billion working capital cash outflow.

- $443M Mongolian tax dispute could escalate if not resolved.
- Working capital outflow of ~$1.2B pressures near-term free cash flow.
- Yarwun alumina refinery 40% production cut from October 2026.
- Simandou ramp-up dependent on permanent crushing facilities delivery in H2 2026.
