Rio Tinto’s Record Rally Faces a Test as Lithium Projects Gear Up

Rio Tinto shares hit near all-time highs as Q1 copper-equivalent output rises 9%, lithium projects ramp up, and cost efficiencies boost margins despite weather disruptions.

Rio Tinto’s stock has been on a tear, surging roughly 51% since the start of the year and trading at €104.58 — just shy of its all-time high of $174.79 reached on April 22. The rally, which has seen the shares climb 37% in the past 30 days alone, reflects a market increasingly convinced that the mining giant’s operational turnaround is sustainable. But with the shares up 92% over the past 12 months, the question now is whether the next leg of growth can match the momentum.

The first-quarter production numbers provide plenty of ammunition for bulls. Rio Tinto’s copper-equivalent output rose 9% year-on-year, driven by a standout performance from its Pilbara iron ore operations in Western Australia. Production there jumped 13%, marking the second-strongest opening quarter since 2018. That was despite two tropical cyclones that knocked about 8 million tonnes off shipments. The company expects to claw back roughly half of those losses over the coming months, and overall sales still managed to edge above the prior-year level.

The copper division also delivered, with consolidated output climbing 9%, helped by the ramp-up at Oyu Tolgoi in Mongolia and the start of drilling at the Resolution project in the US. In aluminium, bauxite production took an 11% hit from severe weather, but output of primary aluminium and alumina still ticked higher.

Investors have also taken note of the cost side of the equation. Rio Tinto’s efficiency programme, targeting $650 million in annual productivity gains, has already been delivered ahead of schedule. That has helped shore up margins even as the company navigates a volatile commodity price environment.

Perhaps the most closely watched storyline, however, is the lithium push. The group produced 12,700 tonnes of lithium carbonate equivalent in the first quarter, with heavy rains in South America hampering the Olaroz and Fenix operations. But the ramp-up of the new Rincon facility partially offset those losses. The bigger test comes in the second half, when two more projects — Fenix 1B and Sal de Vida — are due to reach mechanical completion and begin first production. Rio Tinto is sticking with its full-year guidance of 61,000 to 64,000 tonnes of LCE.

The market is betting that these new lithium assets will help diversify the company away from its heavy reliance on iron ore, and that the demand cycles for battery metals are increasingly decoupling from traditional economic swings. A smooth start-up in the second half would go a long way toward validating that thesis.

Not everything has gone smoothly. The company reported two fatalities at its Simandou and Kennecott operations earlier this year, prompting a thorough safety review. The Kennecott underground project has since resumed a phased restart since mid-April.

For the full year, Rio Tinto has reaffirmed its production and sales targets across all core commodities: iron ore sales of 343 million to 366 million tonnes, consolidated copper output of 800,000 to 870,000 tonnes, and aluminium production of 3.25 million to 3.45 million tonnes. With the stock already pricing in much of the recent operational strength, the focus now shifts to execution — particularly on the lithium front — and to external factors such as geopolitical developments on global commodity markets.
