The Rio Tinto plc (RIO) SEC filings page provides access to the company’s official disclosures as a foreign private issuer, including Form 20-F annual reports and Form 6-K current reports.

Recent Form 6-K filings reference a wide range of information relevant to investors, such as production results, capital markets presentations, operating model updates, changes in total voting rights and issued capital, dividend notifications and director interest notices. They also include media releases and stock exchange announcements on topics like lithium Mineral Resources and Ore Reserves, the Salares Altoandinos lithium project in Chile, the Rhodes Ridge Joint Venture feasibility study in the Pilbara, and Rio Tinto’s Nuton technology for copper.
Through these filings, investors can follow how Rio Tinto reports on critical minerals projects in Argentina and Chile, joint ventures such as La Granja in Peru, and agreements with partners and Indigenous organisations.

This makes it easier to understand the regulatory record behind Rio Tinto’s iron ore, copper, aluminium, scandium and lithium businesses without reading every page in detail.
Rio Tinto reported strong fourth quarter and full-year 2025 operating results, highlighted by an 8% year-on-year increase in copper equivalent production and 5% higher shipments. Pilbara iron ore achieved record quarterly production and shipments in Q4, with full-year Pilbara shipments of 326.2 Mt on a 100% basis, only slightly below 2024 despite earlier cyclone disruption. Copper production on a consolidated basis rose 11% to 883 kt for 2025, driven by the ramp-up of Oyu Tolgoi, where underground development is now complete and delivering record quarterly output. Bauxite reached a record 62.4 Mt, up 6%, aluminium rose 3% to 3.38 Mt and lithium carbonate equivalent production was 57 kt, reflecting growth in Argentina operations. The company met or exceeded its 2025 production guidance across product groups and kept 2026 production guidance unchanged from prior disclosures, while exploration and evaluation expense fell to $795 million from $935 million in 2024.
Rio Tinto filed a Form 6-K summarising a series of December 2025 announcements by Rio Tinto plc and Rio Tinto Limited. The report bundles stock exchange notices and media releases on capital structure, management shareholdings, project development and community agreements.
Key items include an updated total voting rights and issued capital statement, several disclosures on shareholdings of persons discharging managerial responsibility and key management personnel, and notifications of unquoted equity securities and director interest changes. Operationally, the exhibits cover initial reporting of lithium Mineral Resources and Ore Reserves, a lithium-focused investor "Deep Dive" and site visit to Argentina, first copper produced using Rio Tinto’s Nuton technology, and a media release on battery-electric haul trucks in the Pilbara with BHP. The filing also highlights Indigenous agreement updates and a $191 million feasibility study for the Rhodes Ridge Joint Venture on an iron ore mine of up to 50Mtpa in the Pilbara.
Rio Tinto PLC filed a 6‑K that compiles recent Stock Exchange announcements covering changes in shareholdings by senior personnel, a director's interest notice, notifications about the interim dividend and its currency exchange rates, and a note on total voting rights and issued capital.

Rio Tinto plc and Rio Tinto Limited filed a Specialized Disclosure Report on Form SD for the fiscal year ended December 31, 2024, to comply with U.S. rules on reporting payments by resource extraction issuers. Instead of providing a separate, detailed payment schedule in this document, Rio Tinto uses an allowed alternative reporting regime and points to its 2024 UK Payments to Governments Report filed at Companies House under the UK Reports on Payments to Governments Regulations 2014. That UK report, which the SEC recognizes as an acceptable substitute, covers payments made by Rio Tinto and its subsidiaries to governments and is incorporated here through reference and as exhibits. The company also provides an interactive XBRL data file and the full UK report as exhibits to this filing.
Rio Tinto plc and Rio Tinto Limited submitted a Form 6-K as foreign private issuers. The filing primarily forwards a stock exchange announcement dated 27 August 2025 titled “Rio Tinto announces operating model and executive team updates to unlock additional shareholder value.”
The Form 6-K itself is administrative, indicating that the detailed information on changes to the operating model and executive team is contained in Exhibit 99.1, rather than in the body of this report.
