Notice to ASX/LSE Changes to the Classification of Rio Tinto Key Management Personnel 1 January 2021 Consistent with our efforts to simplify and align activities across the Group, and to coincide with the review of our next Remuneration Policy ahead of it being submitted for shareholder approval at our 2021 AGMs, the Board has agreed a change to the classification of executives designated as Key Management Personnel (KMP) under the Australian corporations legislation. Effective 1 January 2021, all non-executive directors, the Group Chief Executive and the Chief Financial Officer, all Product Group Chief Executives, the Chief Commercial Officer and the Group Executive Strategy & Development, will remain classified as KMP. The Group Executive Human Resources, the Group Executive Group General Counsel and the Group Executive Safety Technical & Projects, will not be classified as KMP from 1 January 2021. This change has been made to align those executives classified as KMP with those classified as Persons Discharging Management Responsibilities (PDMR) under UK legislation. In addition to this change, there will be two further title changes made. Vera Kirikova, whose current title is Group Executive Human Resources, will take on the title of Chief People Officer, and Barbara Levi, whose current title is Group Executive Group General Counsel, will take on the title of Chief Legal, Governance & Ethics Officer. These changes will also be effective 1 January 2021. This announcement is authorised for release to the market by Rio Tinto's Group Company Secretary.

Media Release Rio Tinto enters scandium market with construction of new plant in Canada 14 January 2021 SOREL-TRACY, Canada – Rio Tinto will become the first producer of high-quality scandium oxide in North America, with construction of a new commercial scale demonstration plant underway at its Rio Tinto Fer et Titane (RTFT) metallurgical complex in Sorel-Tracy, Quebec. RTFT expects to begin commercial supply of scandium oxide in the second quarter of 2021. With its world-class aluminium business, Rio Tinto is also well positioned to produce aluminium-scandium alloys to meet customer’s needs. Rio Tinto is investing US$6 million for the construction of a first module in the plant, with an initial capacity to produce three tonnes of scandium oxide per year, or approximately 20% of the current global market. The Government of Quebec is contributing approximately US$650,000 to the project through the Quebec Plan for the Development of Critical and Strategic Minerals. The new plant will have the ability to add further modules in line with market demand. RTFT developed an innovative process it has proven at pilot scale to extract high purity scandium oxide from the waste streams of titanium dioxide production, without the need for any additional mining at its ilmenite mine in Havre-Saint-Pierre, Quebec. Scandium oxide is used to improve the performance of solid oxide fuel cells, which are used as a power source for data centres and hospitals, as well as in niche products such as lasers and lighting for stadiums or studios. It is also used to produce high-performance aluminium-scandium master alloys for the aerospace, defence and 3D printing industries. Rio Tinto Iron and Titanium managing director Stéphane Leblanc said “We are proud to offer North America’s first reliable supply of scandium oxide using an innovative and sustainable process, with the construction of this new plant. Rio Tinto has been engaged in the exploration and production of rare earths and critical minerals globally for a number of years, to meet the demand in new and emerging technologies. With the support of Rio Tinto’s aluminium business, we are uniquely positioned to deliver aluminium-scandium master alloys and develop synergies with North America’s manufacturing supply chain.” Quebec Minister of Energy and Natural Resources Jonatan Julien said “RTFT's scandium oxide valorization project is a concrete example of how we can extract value from our mining wastes. It demonstrates our ability to innovate and seize business opportunities in a growing market as we strive to ensure secure supplies of critical minerals. This business has the potential to become a major scandium supplier outside China.” Quebec Minister of Economy and Innovation Pierre Fitzgibbon said “The step just taken today by Rio Tinto Fer et Titane has the potential to position Quebec as a world leader in the extraction and commericalisation of scandium. With this project, Quebec will become the largest producer of this rare metal, which will have a major impact on our exports and Quebec’s supply chains, particularly in key sectors such as the electrification of transportation and aerospace. I commend the entire RTFT team for this project, which combines innovation and responsible use of our resources.” Both the high quality scandium oxide and aluminium-scandium master alloy will be commercialized under the business brand name Element North 21.

Notes to editors Rio Tinto Fer et Titane (RTFT) operates an open cast ilmenite mine at Lac Tio near Havre-Saint-Pierre, on Quebec’s North Shore. The ore is then sent by boat to its metallurgical complex in Sorel -Tracy, Quebec, where high-quality titanium dioxide feedstock, pig iron, steel and metal powders are extracted. Together, the sites employ over 1,600 people. RTFT has operated in Quebec for 70 years and pioneered the process of removing iron from ilmenite. In the last decade, RTFT has focused on developing, marketing and fine-tuning the UGS process, which produces slag with a very high titanium dioxide content sold to pigment producers. Founded in 1967, RTFT’s Research & Development Centre conducts research on process improvement and develops new products. The Centre features state-of-the-art equipment and highly specialised instruments, such as inductively coupled plasma spectrometers, X-ray machines, atomic absorption units, gas and image analysers and scanning electron microscopes.

Notice to ASX/LSE Page 1 of 2 NZAS reaches deal with Meridian to extend operations to 2024 14 January 2021 Rio Tinto has reached an agreement on a new electricity agreement with Meridian Energy that allows New Zealand’s Aluminium Smelter (NZAS) to continue operating the Tiwai Point aluminium smelter until December 31, 2024. The extension provides certainty to employees, the local community and customers while providing more time for all stakeholders to plan for the future. While discussions with the New Zealand government are progressing in relation to their commitment to address the smelter’s high transmission costs, a new agreement has been reached with Meridian Energy in relation to power prices, making the smelter economically viable and competitive over the next four years. The extension also provides time for detailed closure studies to be completed and for NZAS to support the government and Southland community in planning for the future. Plans for eventual closure of the Tiwai Point smelter will include extensive stakeholder consultation, including within the Southland community and reflect the company’s robust closure and remediation standards. Rio Tinto Aluminium chief executive Alf Barrios said “We are pleased to have reached an agreement with Meridian Energy that will enable the Tiwai Point smelter to continue producing some of the lowest carbon aluminium in the world. This agreement improves Tiwai Point’s competitive position and secures the extension of operation to December 2024. It also provides Rio Tinto, the New Zealand government, Meridian, and the Southland community more time to plan for the future and importantly gives our hard-working team at Tiwai and our customers the certainty they deserve.” In July 2020, Rio Tinto announced the conclusion of a strategic review of the smelter and a decision to wind down operations by August 2021 due to high energy and transmission costs. NZAS is a joint venture between Rio Tinto (79.36%) and Sumitomo Chemical Company Limited (20.64%). It employs around 1000 people directly and creates a further 1600 indirect jobs in Southland.
