Rio Tinto Refreshes $10 Billion Debt Programme as Copper and Lithium Spending Builds

LONDON, April 1, 2026, 14:01 BST

Rio Tinto plc published a supplementary prospectus for its U.S.$10 billion Euro Medium Term Note programme on Tuesday, refreshing an existing debt framework as the miner keeps funding channels open. The filing, approved by the UK Financial Conduct Authority, covers notes issued by three Rio Tinto Finance (USA) entities and guaranteed by Rio Tinto plc and Rio Tinto Limited. 1

The timing matters. Rio is spending heavily on copper and lithium while recent cyclone damage has hit shipments from its Pilbara iron ore system, still the group’s main earnings base. In February, Rio said operating cash flow rose to $16.8 billion in 2025, but free cash flow fell 28% and net debt climbed to $14.36 billion; days ago, it said Cyclone Narelle had disrupted Pilbara shipments without knocking it off full-year guidance. 2

Tuesday’s notice was limited to publication of the updated prospectus for the existing $10 billion programme. In simple terms, an EMTN programme is a standing bond framework that lets a company return to debt markets more quickly when it wants to sell notes. 1

Chief Executive Simon Trott said with Rio’s annual results that the company would keep investing in “value-accretive growth” and that its “strong cash flow and balance sheet” supported shareholder returns. Rio also said it remained on track for 3% compound annual growth in copper-equivalent output to 2030, a measure that converts different mined products into copper value so investors can compare growth across the portfolio. 3

The spending list is long. Rio secured a $1.175 billion financing package in March from four international lenders for the Rincon lithium project in Argentina, saying the money would diversify funding sources for the $2.5 billion development. 4

On copper, Katie Jackson, head of Rio’s copper business, told Reuters last week the company was “quite committed to bringing copper on as quickly as we can” at Resolution Copper in Arizona and wanted output in the early- to mid-2030s. Rio has already started a $500 million drilling campaign after gaining control of key acreage at the site. 5

The wider sector is moving the same way. BHP, Rio’s closest rival, has put copper at the centre of its growth pitch too, with incoming CEO Brandon Craig saying any merger or acquisition would have to be “incredibly compelling” against its existing project options. Rio, for its part, abandoned takeover talks with Glencore in February and went back to its internal pipeline. 6

“It is possible that the two companies re-engage at some point in the future, but that is not our base case,” Jefferies analyst Christopher LaFemina said after the Glencore talks collapsed, adding Rio would likely go it alone. Later that month, Rio said it was testing market interest in selling its titanium and borates business and looking at ways to monetise infrastructure across divisions. 7

That does not remove the near-term risks. Rio said on March 30 that Cyclone Narelle had cut expected iron ore shipments by about 8 million metric tons, though it kept 2026 Pilbara guidance unchanged at 323 million to 338 million tons and said it could recover roughly half the lost volumes. 8

A weaker iron ore market, more weather disruption in Australia, or setbacks in Mongolia and Arizona could shift the funding picture again. Jackson said Rio was open to lowering management fees and interest charges in talks with Mongolia over Oyu Tolgoi, but warned the company was carrying “a very real and significant risk” there. 5
