$RIO · RIO TINTO PLC
Rio Tinto filed its Q3 2026 production results via 6-K. Copper equivalent production rose ~1% YTD, driven by Oyu Tolgoi copper (+27% YoY in Q3, +29% YTD) and Pilbara iron ore. Simandou achieved a ~10 Mtpa annualised production run-rate (100% basis) and remains on track for 60 Mtpa by H2 2028. All 2026 production and unit cost guidance is unchanged. The company has achieved more than $2 billion of capital release year-to-date under its $5-10 billion program.
- Oyu Tolgoi copper production rose 27% YoY in Q3 to 114kt, running at a ~450 kt annualised rate.
- Simandou iron ore achieved a ~10 Mtpa (100% basis) annualised production run-rate in Q3; remains on track for 60 Mtpa by H2 2028.
- Pilbara iron ore sales of 85.7 Mt (100% basis) were up 2% YoY; full-year guidance of 323-338 Mt unchanged.
- Rio Tinto has achieved more than $2 billion of capital release year-to-date under its $5-10 billion program.
- Lithium carbonate equivalent production rose 33% YTD to 40.3 kt, though full-year guidance is tracking at the lower end of 61-64 kt.
RIO shares down 2.05% to $91.15 in regular trading, with a modest -0.19% move since filing. The decline likely reflects broader macro pressure (iron ore prices down 8% QoQ, lithium carbonate down 14% QoQ) outweighing the operational positives.
Rio Tinto's two highest-growth assets — Oyu Tolgoi copper and Simandou iron ore — both hit key ramp-up milestones in Q3, validating the company's growth pipeline to 2030.
Copper market remains extremely tight with LME prices hitting a record $6.74/lb in August and spot TC/RCs at a record low of -$267/t. Iron ore prices held a narrow $97/dmt band but higher seaborne freight costs compressed producer netbacks, particularly for Atlantic supply.
Middle East conflict continues to drive volatility in energy and freight markets; Strait of Hormuz conditions remain highly volatile. Pilbara unit cash costs face headwinds from higher diesel prices (+$0.9/t YTD, potentially $1.1/t full-year) and adverse FX at US$0.70/A$ vs guidance assumption of US
