Rio Tinto Weathers Cyclone Damage as Low-Carbon Strategy Gains Momentum

Rio Tinto shares double since June 2025 as Q1 output rises 9%, cyclone losses hit iron ore, and lithium projects near first production.

Rio Tinto’s share price is hovering near a 52-week high, having more than doubled since June 2025, as the mining giant navigates a first quarter marked by both operational resilience and a fresh push into sustainable materials. The stock, trading at roughly €105, reflects investor confidence that the company can absorb weather-related disruptions while positioning itself for long-term growth in copper, lithium, and low-carbon aluminium.

Cyclone Narelle Leaves a $3 Million Response in Its Wake

Tropical Cyclone Narelle, a Category-3 system that struck Western Australia’s Pilbara region in late March, combined with Cyclone Mitchell in February to knock out approximately eight million tonnes of iron ore shipments. Rio Tinto responded with a two-tranche humanitarian package totalling A$3 million. On 21 April, the company pledged A$1.5 million for Queensland and the Northern Territory, followed two days later by an additional A$1 million for Western Australia, directed to the state’s emergency services authority, DFES.

In Queensland, A$1 million is being split between the Australian Red Cross and the State Emergency Service, while the Northern Territory receives A$500,000. Employees can also channel donations through the RioGivers programme, with the company matching their contributions.

Despite the weather-induced losses, Rio Tinto is standing by its full-year iron ore shipment guidance of 323 million to 338 million tonnes. Management expects to recover roughly half of the cyclone-related shortfall over the remainder of the year. Heavy rainfall also weighed on bauxite production, which slid 11% to 13.3 million tonnes in the quarter.

Strong First Quarter Underpins the Outlook

The operational picture beyond the weather damage remains robust. Rio Tinto reported a 9% year-on-year increase in copper-equivalent production for the first quarter of 2026, driven by the ramp-up at the Oyu Tolgoi copper mine in Mongolia and a solid performance from its aluminium division. Iron ore output from the Pilbara rose 13%, delivering what the company described as its second-best first quarter since 2018.

Productivity initiatives have already locked in annualised savings of $650 million, and the full-year production and cost forecasts remain unchanged.

Lithium and Copper Projects Inch Closer to Reality

Rio Tinto is simultaneously advancing its next generation of growth assets. The Fenix 1B and Sal de Vida lithium projects have reached mechanical completion, with first production targeted for the second half of 2026. In Arizona, the company has begun drilling at the Resolution Copper project, made possible by a land swap completed in March.

These developments signal Rio Tinto’s intent to diversify beyond its traditional iron ore stronghold and tap into the metals critical to the energy transition.

A Low-Carbon Aluminium Play for the Data Centre Boom

In a move that underscores its sustainability ambitions, Rio Tinto has formed an industrial partnership with cable manufacturer Prysmian. The two companies will jointly develop low-carbon aluminium cables aimed at the rapidly expanding data centre market. Rio Tinto will contribute its smelting technology, while Prysmian brings its cable production expertise. The goal is to reduce the carbon footprint of critical IT infrastructure.

The data centre sector is growing at breakneck speed, and demand for energy-efficient materials is rising in tandem. Whether this partnership translates into meaningful revenue will depend on how quickly low-carbon aluminium becomes the industry standard. The next set of quarterly results will reveal whether the operational momentum can be sustained and whether Rio Tinto can indeed claw back those lost eight million tonnes of iron ore.
