3 January 2023

Total voting rights and issued capital

In accordance with the Financial Conduct Authority’s (FCA) Disclosure Guidance and Transparency Rule 5.6.1R, Rio Tinto plc notifies the market that as of 30 December 2022:

1.Rio Tinto plc’s issued share capital comprised 1,255,843,808 Ordinary shares of 10p each, each with one vote.

2.6,189,083 ordinary shares of 10p each are held in treasury. These shares are not taken into consideration in relation to the payment of dividends and voting at shareholder meetings.

Accordingly the total number of voting rights in Rio Tinto plc is 1,249,654,725. This figure may be used by shareholders (and others with notification obligations) as the denominator for the calculation by which they will determine if they are required to notify their interest in, or a change to their interest in, Rio Tinto plc under the FCA’s Disclosure Guidance and Transparency Rules.

Note:

As at the date of this announcement:

(a)Rio Tinto plc has also issued one Special Voting Share of 10p and one DLC Dividend Share of 10p in connection with its dual listed companies (‘DLC’) merger with Rio Tinto Limited which was designed to place the shareholders of both companies in substantially the same position as if they held shares in a single enterprise owning all of the assets of both companies;

(b)the Special Voting Share facilitates joint voting by shareholders of Rio Tinto plc and Rio Tinto Limited on joint electorate resolutions; and

(c)there are 371,216,214 publicly held Rio Tinto Limited shares in issue which do not form part of the share capital of Rio Tinto plc.

LEI: 213800YOEO5OQ72G2R82

Media release

Nuton Acquires Common Shares of Regulus Resources

30 January 2023

LONDON--(BUSINESS WIRE)-- Rio Tinto venture Nuton LLC (“Nuton”) has completed an arm’s length non-brokered private placement financing with Regulus ("Regulus" or the “Company”) for a strategic investment of US$15 million (C$20,460,1531) (the “Financing”).

Pursuant to the Financing, Nuton was issued 20,058,974 common shares in the capital of the Company (each, a “Common Share”) at an issuance price equal to C$1.02 per Common Share. Upon completion of the Financing, Nuton acquired beneficial ownership and control over 20,058,974 Common Shares representing 16.1% of the issued and outstanding Common Shares on completion on a non-diluted basis.

In connection with the Financing, Regulus and Nuton have entered into a collaboration agreement wherein Nuton was granted certain investor rights, including allowing Nuton to maintain its equity interest in Regulus if it maintains said interest above 10%. Additionally, Nuton shall be allowed to nominate a director to the board of directors of Regulus. The Company and Nuton have agreed to form a joint advisory committee to share expertise, exploration concepts and discuss development opportunities at the Company’s AntaKori project in Peru. The Company has granted exclusivity to Nuton in the area of novel, patented or trade secret leaching technologies, for a period of one year after the delivery of metallurgical samples from AntaKori to Nuton for testing. For a one-year period, Nuton has agreed to not sell any share of Regulus, acquire greater than a 19.9% interest in the Company and vote its common shares in favour of each director nominated by the Company. Nuton acquired the Common Shares for investment purposes.

Notes to editors

Nuton is an innovative new venture that aims to help grow Rio Tinto’s copper business. At the core of Nuton is a portfolio of proprietary copper leach-related technologies and capability – a product of almost 30 years of research and development. Nuton technologies offer the potential to economically unlock copper sulphide resources, copper bearing waste and tailings, and achieve higher copper recoveries on oxide and transitional material, allowing for a significantly increased copper production. One of the key differentiators of Nuton is the potential to deliver leading environmental performance, including more efficient water usage, lower carbon emissions, and the ability to reclaim mine sites by reprocessing mine waste.
