Rio Tinto’s 2026 Spring Rally: Record Output, a Landmark Guinea Shipment, and a Looming Legal Hangover

Rio Tinto enters its AGM with soaring shares and record copper output, but faces legal liabilities, fatal accidents, and royalty disputes.

Rio Tinto is charging into its annual general meeting on May 6 with a formidable hand — a near-doubling of its share price over the past year, a 9% jump in copper-equivalent production, and the arrival of its first commercial iron ore cargo from Guinea’s giant Simandou project in China. Yet beneath the headline strength, the Anglo-Australian miner faces a trio of headwinds: a damaging Australian court ruling over historical royalty payments, a fatal accident at two of its operations, and the lingering question of how much those legal liabilities will ultimately cost.

The operational numbers from the first quarter are undeniably robust. The ramp-up of the underground Oyu Tolgoi mine in Mongolia propelled copper output to 229,000 tonnes, while iron ore production in Western Australia’s Pilbara region logged its second-best start to a year in eight years. That performance came despite tropical cyclones that wiped out roughly eight million tonnes of iron ore shipments; management is confident it can claw back about half of that volume over the remainder of 2026. The full-year Pilbara guidance remains unchanged at between 323 million and 338 million tonnes.

The market has taken notice. Rio Tinto’s shares closed at €105.10 on Tuesday, a whisker below their 52-week high and up almost 52% since January. Analysts have been scrambling to raise their price targets. Argus lifted its target to $120 with a buy recommendation, following similar moves by Bernstein and JPMorgan, which set a target of 7,200 pence but kept a “neutral” rating. Berenberg, more cautious, trimmed its target to 6,600 pence and maintained a “hold.”

Beyond the core mining business, Rio Tinto is making tangible progress on its low-carbon transition. The Fenix 1B and Sal de Vida lithium projects have reached mechanical completion, with first production expected in the second half of 2026. The company has also extended its partnership with the Clontarf Foundation by five years, a program supporting Indigenous youth in the Pilbara that bolsters the miner’s social license to operate in the region.

But the quarter was not without tragedy. Fatal incidents occurred at both the Simandou project in Guinea and the Kennecott mine in Utah. Operations were halted immediately; Kennecott has since resumed production in stages since mid-April.

The most pressing financial uncertainty stems from an April ruling by the Supreme Court of Western Australia. The court found Rio Tinto and its joint venture partner Hancock Prospecting liable for backdated royalty payments to former business partners Wright Prospecting and DFD Rhodes, relating to revenue from certain Pilbara mines. The exact sum will be determined in a separate proceeding, but Hancock has estimated future claims at roughly A$18 million per year. As operator of the Hope Downs joint venture, Rio Tinto carries a share of the liability, and the unresolved quantum is likely to draw pointed questions from shareholders at the AGM in London.

For now, the operational momentum is carrying the day. The Simandou milestone — the first commercial cargo to reach China from Guinea’s massive, long-delayed iron ore deposit — adds a strategic dimension to Rio Tinto’s supply chain that competitors will find hard to match. The question is whether the legal and safety shadows will darken further before the year is out.
