Production Targets The estimated average production of ~500ktpa copper and ~330kozpa gold for the years 2028-2036 referenced on slides 20, 22 and 33 are underpinned as to 13% by Proved Ore Reserves and 87% by Probable Ore Reserves. The estimated average production of ~340ktpa copper and ~360kozpa gold for the years 2023-2027 referenced on slide 33 are underpinned as to 27% by Proved Ore Reserves and 73% by Probable Ore Reserves. The estimated average production of ~290ktpa copper, ~260kozpa gold and ~1,710kozpa silver for the estimated reserve life of approximately 30 years referenced on slide 33 are underpinned as to 26% by Proved Ore Reserves and 74% by Probable Ore Reserves. These production targets are stated as recovered metal and have been scheduled from current mine designs for the Oyu Tolgoi underground and open pit mines by Competent Persons in accordance with the requirements of the Australasian Code for Reporting of Exploration Results, Minerals Resources and Ore Reserves, 2012 Edition. Forward-looking statements This presentation includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts included in this report, including, without limitation, those regarding Rio Tinto’s financial position, business strategy, plans and objectives of management for future operations (including development plans and objectives relating to Rio Tinto’s products, production forecasts and reserve and resource positions), are forward-looking statements. The words “intend”, “aim”, “project”, “anticipate”, “estimate”, “plan”, “believes”, “expects”, “may”, “should”, “will”, “target”, “set to” or similar expressions, commonly identify such forward-looking statements. Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of Rio Tinto, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements, particularly in light of the current economic climate and the significant volatility, uncertainty and disruption arising in connection with the Ukraine conflict and the Covid-19 pandemic. Such forward-looking statements are based on numerous assumptions regarding Rio Tinto’s present and future business strategies and the environment in which Rio Tinto will operate in the future. Among the important factors that could cause Rio Tinto’s actual results, performance or achievements to differ materially from those in the forward-looking statements include, but are not limited to: an inability to live up to Rio Tinto’s values and any resultant damage to its reputation; the impacts of geopolitics on trade and investment; the impacts of climate change and the transition to a low-carbon future; an inability to successfully execute and/or realise value from acquisitions and divestments; the level of new ore resources, including the results of exploration programmes and/or acquisitions; disruption to strategic partnerships that play a material role in delivering growth, production, cash or market positioning; damage to Rio Tinto’s relationships with communities and governments; an inability to attract and retain requisite skilled people; declines in commodity prices and adverse exchange rate movements; an inability to raise sufficient funds for capital investment; inadequate estimates of ore resources and reserves; delays or overruns of large and complex projects; changes in tax regulation; safety incidents or major hazard events; cyber breaches; physical impacts from climate change; the impacts of water scarcity; natural disasters; an inability to successfully manage the closure, reclamation and rehabilitation of sites; the impacts of civil unrest; the impacts of the Ukraine conflict and the Covid-19 pandemic; breaches of Rio Tinto’s policies, standard and procedures, laws or regulations; trade tensions between the world’s major economies; increasing societal and investor expectations, in particular with regard to environmental, social and governance considerations; the impacts of technological advancements; and such other risks identified in Rio Tinto’s most recent Annual Report and accounts in Australia and the United Kingdom and the most recent Annual Report on Form 20-F filed with the United States Securities and Exchange Commission (the “SEC”) or Form 6-Ks furnished to, or filed with, the SEC. Forward- looking statements should, therefore, be construed in light of such risk factors and undue reliance should not be placed on forward-looking statements. These forward-looking statements speak only as of the date of this report. Rio Tinto expressly disclaims any obligation or undertaking (except as required by applicable law, the UK Listing Rules, the Disclosure Guidance and Transparency Rules of the Financial Conduct Authority and the Listing Rules of the Australian Securities Exchange) to release publicly any updates or revisions to any forward-looking statement contained herein to reflect any change in Rio Tinto’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. Nothing in this presentation should be interpreted to mean that future earnings per share of Rio Tinto plc or Rio Tinto Limited will necessarily match or exceed its historical published earnings per share. Past performance cannot be relied on as a guide to future performance. Disclaimer Neither this presentation, nor the question and answer session, nor any part thereof, may be recorded, transcribed, distributed, published or reproduced in any form, except as permitted by Rio Tinto.

Nevertheless, iron ore price support emanated from disruptions to seaborne supply and scrap availability in China – China’s steel demand and production declined by -5% YoY and -4% YoY respectively, but with scrap availability and consumption -12% lower YoY, hot metal output remained largely unchanged close to 880Mt (-1% YoY) – China’s 2022 iron ore imports remained effectively unchanged YoY at almost 1.2Bt, while port inventories were drawn down from 155Mt to 131Mt during the year – Meanwhile, iron ore supply trended below its 2021 and 5-year average levels during most of 2022, due to extreme rainfall in Brazil during Q1, the war in Ukraine, and India’s decision to impose export duties. The major iron ore producers shipped 1.13Bt of iron ore (unchanged YoY), but the remainder of seaborne supply declined -13% YoY, bringing total iron ore exports down - 3.2% YoY 800 850 900 950 1000 1050 1100 1150 1200 Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec 5 Yr Range 2021 5 Yr avg 2022

However, Chinese aluminium export growth slowed from +34% YoY in H1, to +3% YoY in H2 – Aluminium production increased by 2% in 2022, driven by 4% growth in China. But low hydropower generation forced smelter cuts in southern China, resulting in a QoQ decline in Q4 output – Global reported inventories declined substantially in 2022. The market tightness is very clear in the US, where the Midwest premium has now rallied by over 50% from the Q4 low – Copper consumption held up as weakness in residential property was compensated for by strength in EVs, renewables and non-residential construction – Supply disruptions persisted in 2022, mainly from Latin America, limiting supply growth – Visible stocks fell to historically low levels and will require rebuilding in coming years after market deficits – Investors increased their copper position through H2 – TiO2 feedstock price appreciation supported by low inventories and tight supply through 2022 – Demand for TiO2 products was impacted by a weakening macro environment over the second half. This resulted in sales volume declines for pigment producers in North America and Europe – TiO2 feedstock supply growth has been moderate despite rising prices
