Rio's bumper dividend is mostly a copper story

Rio (ASX: RIO) these days is in a position of strategic weakness versus BHP when it comes to iron ore. 

In Western Australia, its mineral endowment simply isn't as good. So, much like the ugly guy on the dating app needs something extra going for him, Rio has always had to be better than BHP in other ways to attract investor capital.

The results look good

These results were perhaps an example of that. Every one of Rio's newly restructured divisions - iron ore, copper, and aluminium & lithium - beat expectations. Net debt came in below forecasts while free cash flow came in well above. Rio's stock is trading up almost 5% since yesterday.

Costs are coming down too - a focus of new boss Simon Trott. And costs aren't just coming down by firing people; productivity gains have been real. With inflation rising thanks to the US–Iran war pushing up energy and input costs, lower costs give Rio a buffer.

Remarkably, all 22 major development projects - Simandou, the Pilbara replacement mines, Argentine lithium, the Oyu Tolgoi underground ramp-up - are on or ahead of schedule.

"The company continues to be a leader in project execution," Goldman Sachs' Paul Young, one of Australia's best mining analysts, said of the results. Young credits decision-making moving away from London and Perth and back to the mine sites as helping here.

The cherry on top for shareholders: a large dividend (US$2.11 a share, up 43%) deriving heavily from a big swing in copper profits, which we discuss below.

Copper to the future

Beyond the dividend, copper is shaping the company's future.

The headline Rio ran with was that it is no longer mostly an iron ore miner: copper, aluminium and lithium together delivered more than half of its profit. (Caveat: Rio says this while simultaneously chasing higher iron ore grades in Africa with Chinese partners.)

Copper alone was the standout: profits jumped 84% to US$5.7 billion, to around 36% of group earnings, and are now chasing down iron ore's US$6.8 billion, which was flat despite record first-half Pilbara production.

Lithium, copper's energy-transition cousin, matters more now too, despite the sledgehammer Trott took to the division on arrival. It will contribute less than 2% of earnings next year, but the Arcadium acquisition - struck near the bottom of the market in late 2024 - leaves Rio near the bottom of the cost curve with a front-row seat on direct lithium extraction, a technology that threatens to steepen that very curve. (Hence plans to triple output within 24 months as the lithium winter thaws.)

Rio's copper weakness: a thinner pipeline

Back to copper: if there's a gripe (UBS has made it), it's that Rio's pipeline thins out beyond 2030. 

Viewing this, Rio is drilling its longer-dated options in earnest. Surface drilling has begun at Resolution in Arizona after Trump greenlit the land exchange; underground drilling starts next quarter. Studies continue at La Granja in Peru. And Rio retains its 30% stake in Escondida, the world's biggest copper mine, alongside operator BHP's controlling 57.5%.

Goldman forecasts Rio's copper-equivalent production growing about 10% between 2025 and 2030 — barely 1% this year, then roughly 3% a year from 2027. 

The drivers are the Oyu Tolgoi underground ramp-up (albeit the Mongolian government has forced Rio to attack lower-grade panels first: a possible ~50kt hit to copper and gold across 2027–28) and higher grades at Bingham Canyon from 2027.

What are the risks?

For all the copper talk, Rio remains an iron ore and aluminium miner first. Its earnings sensitivities to price swings still skew that way. And this was fundamentally a commodity price-driven half, which is presumably why CFO Peter Cunningham went out of his way to insist it wasn't just a price story.
