Notice to ASX/LSE 5 May 2022 Rio Tinto Limited AGM – Address by the Chairman Simon Thompson, Chairman Rio Tinto Limited 2022 Annual General Meeting, Melbourne **Check against delivery** Good morning to everyone here in Melbourne, and to those of you joining us virtually. My name is Simon Thompson, I am the Chairman of Rio Tinto, and my pleasure to welcome you to our 2022 Annual General Meeting. It’s a particular pleasure to see so many of our shareholders here, in person. We start, as always, with safety – our top priority. So, please take a moment to listen to this short safety announcement. [Safety briefing] In the same way that safety is critically important to us, so too is our respect for the communities that host our operations around the world. It gives me great pleasure to introduce Aunty Diane, who is a senior Elder of the Wurundjeri people, the Traditional Owners of the land on which we meet today. Aunty Diane is accompanied by Mr Eric Edwards on the didgeridoo. [Welcome to Country] Thank you, Aunty Diane for your welcoming words, and to you and Eric for a wonderful opening to our AGM. We are holding this year’s AGM as a hybrid meeting. Shareholders who are unable to attend in person can view the meeting live via the Lumi platform. They will be able to ask questions, either orally or in writing, and to cast their votes through the platform. In addition, a video recording of today’s proceedings will be available on our website after the meeting. The quorum is present, and I now formally open the meeting. It’s my pleasure to introduce my fellow members of the Rio Tinto Board. Starting on my left with Tim Paine, our Australian Company Secretary, Simon McKeon, Senior Independent Director of Rio Tinto Limited, Megan Clark, Chair of our Sustainability Committee, Peter Cunningham, our Chief Financial Officer, Jakob Stausholm, our Chief Executive, and Dominic Barton, my successor as Chair of the Board, Simon Henry, Chair of our Audit Committee, Jennifer Nason and Ngaire Woods. Ben Wyatt and Sam Laidlaw, Senior Independent Director of Rio Tinto plc and Chair of our Remuneration Committee, are here in Melbourne but are unable to attend in person having both tested positive for COVID upon arrival. We also have with us Trevor Hart, our external auditor from KPMG. We have had a number of changes to the Board over the past year. Michael L’Estrange retired at the conclusion of the Rio Tinto Limited AGM in May 2021 and, last month, Hinda Gharbi retired from the Board at the conclusion of the Rio Tinto plc annual general meeting on 8 April. I am very grateful to both Michael and Hinda for their contributions to Rio Tinto. In June, we appointed Peter Cunningham as our Chief Financial Officer and in September 2021, we welcomed Ben Wyatt to the Board. Ben’s knowledge of finance, public policy, trade and Indigenous affairs has already proved to be invaluable. Exhibit 99.1

Notice to ASX/LSE Page 2 of 6 As previously announced, I will step down as Chairman at the conclusion of this meeting. I am delighted that the Board has announced the appointment of Dominic Barton as my successor. Dominic has extensive business and international relations experience, as well as a deep understanding of the linkages between business, governments and society. I wish him every success. Dominic, perhaps I could also ask you to say a few words? [Dominic’s remarks] Thanks, Dominic. As I reach the end of my eight years on the Board, it has been a privilege to be part of the leadership team of this great company. I am proud of the direction that Rio Tinto is taking and of the talent, resilience and commitment of our employees and contractors around the world. I will say more about this in a moment. But first, let’s deal with some of the formalities for the meeting. In order to make today’s proceedings as efficient as possible, I declare that voting on all resolutions is now open. As usual, resolutions will be decided by poll. For those attending online, if you are eligible to vote at this meeting, a polling icon will appear on your screen. Selecting that icon will bring up a list of resolutions and present you with voting options. To cast your vote simply select one of the options. There is no need to hit a submit or enter button as the vote is automatically recorded. For those shareholders here at the meeting itself, if you have already sent in your proxy forms you do not need to vote again but for proxyholders in the room, and those shareholders who have not appointed a proxy and are eligible and wish to vote, you may complete your voting card at any time, and they will be collected at the end of the meeting. I will now make some introductory comments, before handing over to Jakob for his review of the year. 2021 was a year of transition. We appointed a new Chief Executive, a new Chief Financial Officer and nine members of ExCo took on new roles. Following this unprecedented period of management change, we focused on rebuilding relationships and strengthening our social licence, while setting out a new strategy that seeks to re-establish Rio Tinto as a leader in an industry that has a critical role to play in creating a sustainable and prosperous future for people and for the planet. Following engagement with management and the Board, the new senior management team, led by Jakob, has established four objectives. In the opening video, you saw some of the important work going on around the business globally in pursuit of these objectives, and Jakob will speak further about our progress shortly. In addition, we rolled out three new values – care, courage and curiosity – and a new strategy with the energy transition at its heart. We are now focused on delivering the strategy, in collaboration with our partners and other stakeholders. In 2021, we achieved our third fatality-free year in a row. This achievement reflects the hard work and dedication of our employees and contractors worldwide. Sadly, however, people are still getting injured at work, so we must remain vigilant and focused. While some countries adapted to life with COVID-19, the pandemic continued to exact a heavy toll during 2021, particularly in some of the developing countries where we operate. I am very proud of the resilience and care shown by everyone in the business, for each other, and for their local communities. Our responsibility for the wellbeing of our employees and contractors extends beyond the traditional areas of health and safety. In 2021, we launched the Everyday Respect initiative to help us create a safer, more respectful and more inclusive environment by preventing, and improving how we respond, to unacceptable behaviour in the workplace.

Notice to ASX/LSE Page 3 of 6 I am grateful to Liz Broderick, former Australian Sex Discrimination Commissioner, for advising the Everyday Respect task force that we set up to drive this initiative, and to the more than 10,000 employees and contractors worldwide who participated in listening sessions and surveys as part of the discovery phase. The findings in the report are deeply confronting, and we are determined to implement all 26 recommendations set out in the report. It is clear, both from the findings of the Everyday Respect taskforce and the tragedy at Juukan Gorge, that we must create a work environment where everyone feels safe and empowered to speak up if something is not right. Our 2021 operating and project development performance was negatively impacted by COVID-related travel restrictions, labour shortages, supply chain disruptions, and the transition to improved communities and heritage management processes in the Pilbara and elsewhere. Nevertheless, we achieved record financial results on the back of high commodity prices, with underlying earnings of US$21.4 billion and free cash flow of US$17.7 billion. The Group’s direct economic contribution to the countries where we operate, including payments to our employees, our suppliers, governments, local communities and our shareholders, amounted to US$67 billion. We paid US$13.3 billion in taxes and royalties globally, including A$14.8 billion, here in Australia. In view of this strong financial performance, we have paid a final dividend of 417 US cents per share, and a special dividend of 62 US cents per share. This represents our highest ever total dividend of some US$16.8 billion, or A$14.23 Australian per share. I am now going to focus on climate change, which is the defining issue for our age, and is at the heart of our new strategy. Rio Tinto has a critical role to play in the energy transition, supplying essential materials, including copper, lithium, high-grade iron ore and aluminium, all of which are vital for the transition to a low carbon economy. Our new strategy sets out our plans to grow production in each of these metals. And we have made significant progress in this area with the acquisition of the Rincon lithium project in Argentina and the commencement of underground mining at Oyu Tolgoi in Mongolia. Most recently, the Board has given in- principle approval of the path forward for the development of the Simandou iron ore project in Guinea, in line with international ESG and compliance standards. We also have a responsibility to reduce the Scope 1 and Scope 2 carbon emissions from our operations. The materials we produce already have a much lower carbon intensity than most of our competitors, and we have set ambitious new targets for a 15% reduction by 2025, and a 50% reduction by 2030. To thrive in the long term, we also need to be part of net zero value chains, particularly for steel and aluminium. Our fourth TCFD-aligned Climate Change Report, published in February this year, sets out our goals, working in collaboration with our customers and suppliers, to reduce our indirect Scope 3 emissions. In recognition of the urgent need for action on climate change, by business, governments, consumers and investors, we are for the first time this year putting our Climate Action Plan to our shareholders for an advisory vote, in Resolution 17. We continue to implement the recommendations arising from the Juukan Gorge tragedy in May 2020. In September last year, we published an interim report on our Communities and Social Performance commitments. And there is a huge amount of work going on to improve our processes and build mutually beneficial and respectful partnerships with Traditional Owners and other First Nations peoples around the world. It is a multi-year journey, but we are making good progress – such as the agreement with the Yinhawangka Aboriginal Corporation – the first of our new generation of agreements with Australian Traditional Owners, which sets out our approach to the co-management of culture and heritage, and offers a template for future agreements in the Pilbara.

Notice to ASX/LSE Page 4 of 6 We have emerged from the challenges of the past few years with a firm commitment to become a more inclusive, respectful and caring company, that creates value for all stakeholders. We have set out a new strategy that will re-establish Rio Tinto as a leader in an industry that has a uniquely important and challenging role to play in creating a sustainable and prosperous future for people and the planet. With the new senior management team and the new strategy in place, 2022 is all about delivering our strategy, in collaboration with our partners and other stakeholders. Let me finish by thanking my colleagues on the Board, and especially Jakob, for their hard work, commitment, and dedication to Rio Tinto over the past year and for their insights, advice and support during my time as Chairman. I will now ask Jakob, our Chief Executive, to give us an update on the business. [Jakob speech] Thank you, Jakob. Let’s now move to the formal business of the meeting. The notice of meeting, containing the text of each resolution, was published on our website and made available to shareholders on 8 March. I will take the notice, as read. Resolutions 1 to 17 and 19 will be dealt with under the joint electorate procedure with Rio Tinto plc shareholders, who cast their votes on these resolutions at the corresponding meeting in London, on 8 April. Resolutions 1 and 4 to 15 relate to the routine business of annual general meetings, such as the receipt of the Annual Report, the election and re-election of directors, and the re-appointment and remuneration of the auditors. You will see that the business of the meeting includes two resolutions relating to remuneration. The first, resolution 2, relates to the approval of the Implementation Report, which describes the remuneration arrangements in place for members of the Board and of the Executive Committee during 2021. This vote is advisory and is required for UK law purposes. The second, resolution 3, relates to the approval of the Directors’ Remuneration Report. This vote is also advisory and is required for Australian law purposes. In addition, as a result of our 2020 Remuneration Report receiving a ‘first strike’ at last year’s AGMs, a further conditional resolution, resolution 19, appears on this year’s notice of meeting. If we receive a ‘second strike’ this year, with more than 25% of shareholders voting against resolution 3 in relation to our 2021 remuneration report, the votes on resolution 19 would be valid, and, if resolution 19 is passed, we would be required to convene a separate general meeting to consider fresh elections for directors. If, however, the 2021 Remuneration Report receives a vote of 75% or more in favour, then there will be no ‘second strike’ and the poll on Resolution 19 will not be required. As in past years, we have included a resolution seeking authority for Rio Tinto to make political donations. We have no intention of altering our policy, which is not to make donations to political parties or to political candidates. However, the UK law on this issue is very broadly drafted. So, we are seeking this authority, as a precautionary measure. In addition, for the first time this year, we are putting forward a non-binding, advisory resolution, giving shareholders the opportunity to vote on the Climate Action Plan set out in our 2022 Climate Change Report. Finally, resolution 18 will be voted on by Rio Tinto Limited shareholders only and has been proposed as a special resolution. It is a routine resolution which comes up every year, to allow Rio Tinto Limited to buy back its own shares.

Notice to ASX/LSE Page 5 of 6 Your directors are unanimously of the opinion that all the resolutions proposed in this notice, except for Resolution 19, which is the conditional resolution regarding the holding of fresh elections for directors, are in the best interests of shareholders and of Rio Tinto as a whole. Accordingly, we recommend that you vote in favour of all the resolutions, except Resolution 19, where we recommend that you vote against. We will now take questions from shareholders on any matters relevant to the business of the meeting. Only shareholders or their representatives or proxyholders are entitled to ask questions. [Q&A] Ladies and gentlemen – that brings us to the end of the meeting. I would like to thank all of you for your participation in today’s meeting and continued support of Rio Tinto. For those of you here in the room with us today, I hope that you will join my fellow directors and members of the executive team for some refreshments in the Lounge. There will be signs outside to show you the way. And as you leave, please remember to hand in your completed poll cards. I now declare the meeting closed.

EX-99.2

Notice to ASX/LSE 5 May 2022 Rio Tinto Limited – Address by the Chief Executive Jakob Stausham, Chief Executive Rio Tinto Limited 2022 AGM Annual General Meeting, Melbourne **Check against delivery** Thank you, Simon. First, I would like to acknowledge and pay my respects to the Wurundjeri people, the Traditional Owners of the land on which we meet today, and all Traditional Owners and First Nations people that host our operations around the world. 2021 was a defining year. When I became Chief Executive, it was clear that we needed a reset. We needed a clear sense of purpose – putting respect for people, communities and land at the heart of our contribution. And we needed to listen. We produce materials vital for the energy transition. But that’s not enough. The way we produce these essential materials is what will make the difference – to our customers, to host communities and governments, and to you, our shareholders. We must align our business priorities with society’s expectations and ensure all our stakeholders benefit from our success. We have a lot of work to do – but we are on the right path. We implemented the biggest management change in our history and set four objectives essential to our success: being the best operator, achieving impeccable ESG credentials, excelling in development, and strengthening our social licence. We launched our new strategy, including ambitious climate change targets, setting a new direction for us to contribute to, and thrive in, a decarbonising world. And we set new, simple values that connect us all as human beings – care, courage and curiosity. I would like to take a moment to talk about the humanitarian crisis in Ukraine, which has caused enormous suffering to innocent people. I join the world in condemning the violence and hoping for a peaceful and rapid end to this conflict. We have no operational assets or employees located in Russia or Ukraine; however, we are taking action in a few areas. Firstly, we are in the process of terminating all commercial relationships we have with Russian businesses. Most recently, we now have 100% capacity of Queensland Alumina Limited, which was previously operated through a joint venture with Rusal. We remain committed to ensuring the continued safe operation of QAL, as a significant employer and contributor to the local Gladstone and Queensland economies. In 2021, we maintained our commitment to safety first. The ongoing pandemic has touched all of us in some way. Sadly, we have lost colleagues, family and friends around the world to this virus. I’d like to take this opportunity to sincerely thank our people for their commitment, resilience and sacrifice during another COVID-constrained year. They have done a superb job. I am very proud. Exhibit 99.2

Notice to ASX/LSE Page 2 of 5 We continue to prioritise controls, support government vaccination campaigns and clinics near our operations and working to help our colleagues and communities with vital supplies. Despite the ongoing pandemic, we delivered a strong safety performance with zero fatalities for the third consecutive year. While this is great news, being able to go home to family at the end of a shift should be a given, not an achievement. The independent study on Workplace Culture conducted by former Australian Sex Discrimination Commissioner, Liz Broderick, allows us to understand the experiences of our workforce and how we can prevent and respond to harmful behaviours. The findings are deeply disturbing. Many of our employees have experienced bullying, racism and sexism. I offer my heartfelt apology to every team member, past and present, who has suffered because of these behaviours. This is not the kind of company we want to be. The report also contained 26 detailed recommendations. We will implement them all. We have already upgraded some site facilities and launched our new confidential reporting programme, MyVoice. With the executive team’s commitment, we can make a positive and lasting change and make Rio Tinto a less hierarchical, more humane place to work. Our financial performance in 2021 was very strong and demonstrated both the quality of our assets and the strength of our business model. The recovery of the global economy, driven by industrial production and high demand for our products, resulted in significant price strength for our major commodities. As Simon noted, we have achieved record financial results in 2021, with EBITDA of US$38 billion and net earnings of US$21 billion. Each of our four product groups was highly profitable. Our Iron Ore business continues to be the primary contributor, but we also benefited from an increased contribution from the other three product groups. Aluminium for example, recorded 20% return on capital employed in the second half of 2021, up from just 3% during 2020. A highlight for me comes when you compare the results for 2021 with a similar period of strong demand and prices a decade ago. Last year, we converted a far higher proportion of prices into earnings. And, because of our strict capital allocation, we converted these earnings into higher free cash flow of US$17.7 billion. This enabled us to declare record dividends of US$16.8 billion, a 79 per cent pay-out ratio. In 2021, we made progress against each of our objectives – but we know we have a lot ahead of us. One of our objectives is to restore our reputation as best operator. The Rio Tinto Safe Production System will empower our people to achieve consistent operational performance and unlock real and sustainable improvements at each of our assets. We have deployed it at five sites, and we will be rolling it out at many more, with up to 30 deployments at 15 sites over the coming months. Our second objective is to have impeccable ESG credentials. We provide materials to help the world progress. We have a responsibility to produce these materials in the right way. Society is demanding a greater commitment on climate change. Our new strategy includes ambitious climate targets. The first step is to address our own footprint. We have brought forward our 15% reduction target for our Scope 1 and 2 emissions from 2030 to 2025, and we more than tripled the target for 2030, seeking to reduce our carbon footprint by 50%. Rio Tinto is among the biggest electricity users in the Western world and also has significant land holdings. This provides a great opportunity, but also comes with a great responsibility. Our new climate targets are underpinned by an intention to invest US$7.5 billion. We will be disciplined, and these investments will, in aggregate, be value accretive at modest carbon prices.

Notice to ASX/LSE Page 3 of 5 We are mobilising the organisation, unleashing the skills and creativity of our many engineers to identify opportunities to decarbonise our assets and invest in renewable power. Construction of our first 34MW solar plant at the Gudai-Darri mine and 45MW battery system at Tom Price continued in 2021 and mark an important step in reducing our carbon footprint in the Pilbara. The solar plant will deliver approximately one third of Gudai-Darri’s average electricity demand. It is a first step in a broader programme to leverage the Pilbara’s natural advantages in solar and wind resources and deploy renewable power at scale. We recognise that processing our products also generates material indirect Scope 3 emissions. We are partnering on a number of potential technologies to decarbonise our value chains, including with BlueScope and POSCO, to explore low-carbon steelmaking pathways. And we have committed to increasing our R&D spend to speed up the development of technologies to enable our customers to decarbonise. In Aluminium, our ELYSIS joint venture with Alcoa, supported by Apple and the governments of Canada and Quebec, have already produced aluminium with zero direct carbon emissions at a fairly large scale. We are now scaling up to full commercial size cells in 2023 and commercialisation of this ground-breaking technology remains on track from 2024 onwards. We are investigating iron making with Pilbara fines using sustainable raw biomass to replace coking coal, and microwaves as a supplementary energy source. Initial test results are promising. We are now progressing the design of a larger scale continuous pilot plant. The third objective is to excel in development. All the materials we produce today are fundamental for the energy transition and beyond, including iron ore. We are well placed to grow and meet the increased demand. In the past year we have made meaningful progress on creating a pipeline of options that will create value for our shareholders in the years to come. Our ambition is to increase our investment in growth capital up to US$3 billion annually by 2023 to 2024, and to prioritise commodities that are essential for the drive to net zero. And we have demonstrated our willingness to grow via acquisitions. The Rincon lithium project in Argentina brings growth in a commodity essential to the energy transition, while at Oyu Tolgoi our proposal to acquire full ownership of Turquoise Hill will simplify the ownership structure and provide additional exposure to copper. We believe the terms of proposal are compelling for Turquoise Hill shareholders, and Rio Tinto will remain disciplined in pursuing this opportunity. Without a doubt the most significant development in terms of growth was resetting the relationship with the Government of Mongolia and Turquoise Hill. One of the highlights of my career was to stand side-by-side with the Prime Minister of Mongolia as we commenced underground mining. It was the culmination of years of hard work and dedication to develop such a complex greenfield project. We continue to look for new options and innovative ways of developing projects faster, but we will only do this in line with our ESG standards, while maintaining our absolute commitment to capital discipline. An example of this approach in action is Simandou. This project will deliver the high-grade iron ore essential to decarbonising the world’s steel industry. Last month, the Board gave its in-principle approval to the path forward for the project. The Framework Agreement recently signed with the Government of Guinea and our Chinese joint venture partners sets out co-development of the port and rail infrastructure, which will occur in line with international ESG and compliance standards. We look forward to working together to develop this nation-transforming project and I am personally committed to ensuring that the people of Guinea benefit from Simandou along with our shareholders and customers. In 2021, we committed US$2.4 billion to the Jadar lithium-borates project, one of the world’s largest greenfield lithium projects. In January 2022, the Government of Serbia cancelled the Spatial Plan for the project and required all related permits to be revoked. We remain committed to exploring all options and are reviewing the implications for our activities and our people in Serbia.

Notice to ASX/LSE Page 4 of 5 The fourth objective is to strengthen our social licence. We are focussed on listening and resetting relationships. This takes time, but we are moving forward on a model which is respectful and looks to provide certainty of protection for cultural heritage and mining. In February this year, we announced an agreement with the Yinhawangka Aboriginal Corporation. The co- designed management plan will ensure protection of significant social and cultural heritage values at the Western Range iron ore project in the Pilbara. We are continuing to improve our approach and we are engaging with other Traditional Owner groups in the Pilbara to develop similar plans. The discovery at the Yirra rock shelter, which confirmed the presence of the Yinhawangka people in the region for more than 50,000 years, is incredible news. We are working with Traditional Owners to support the works at this sacred site as our first Traditional Owner-led heritage excavation. We will continue to support more of these significant research projects to ensure we celebrate and care for cultural heritage. As the major shareholder, we were very disappointed to learn of the material cost and schedule over runs on the Ranger rehabilitation project in the Northern Territory announced by Energy Resources of Australia earlier this year. We remain committed to ensuring the rehabilitation project is completed to a standard that will establish an environment similar to the adjacent Kakadu National Park. We also acknowledge the Mirarr People’s concerns around the future of the undeveloped Jabiluka deposit and restate our full support for ERA’s commitment that this deposit will not be developed without their consent. We have a clear direction and strategy for the company to grow and decarbonise. We are rebuilding relationships and evolving our culture, supported by simple, human values. I am proud of the progress we made in 2021. But most of all I am proud of the talented, energetic and committed people across Rio Tinto, like those you saw in the video earlier, who are working hard to make our company even better. It is through working together and listening to the perspectives of all stakeholders, including our customers, host communities and you, our shareholders, that we will achieve our objectives. Our business is strong, and we are all committed to making Rio Tinto even stronger. Finally, I would like to take this opportunity to thank you, Simon, for your guidance and mentorship since I joined the Board. Through your support for transitioning the business to thrive in a low-carbon world, your legacy will be felt long into the future. Thank you.

EX-99.3

Notice to ASX/LSE Page 1 of 12 5 May 2022 Results of Rio Tinto annual general meetings The annual general meetings of Rio Tinto plc and Rio Tinto Limited were held on 8 April 2022 and 5 May 2022 respectively. Under Rio Tinto’s dual listed companies structure established in 1995, decisions on significant matters affecting shareholders of Rio Tinto plc and Rio Tinto Limited in similar ways are taken through a joint electoral procedure. Resolutions 1 to 17 contained in the notices of meeting of each Rio Tinto plc and Rio Tinto Limited, and Resolution 22 in the Rio Tinto plc notice of meeting and the corresponding Resolution 19 in the Rio Tinto Limited notice of meeting set out in tables 1 and 2 below, fall into this category. Resolutions 18 to 21 of the Rio Tinto plc notice of meeting, in table 3 below, were put to Rio Tinto plc shareholders only. Resolution 18 of the Rio Tinto Limited notice of meeting, in table 4 below, was put to Rio Tinto Limited shareholders only. All resolutions were carried, except for Resolution 22 in the Rio Tinto plc notice of meeting and the corresponding Resolution 19 in the Rio Tinto Limited notice of meeting, the poll for which was not valid because more than 75% of the votes validly cast on Resolution 3 (Approval of the 2021 Directors’ Remuneration Report) were cast in favour of that resolution. Resolution 17, to approve Rio Tinto Group’s Climate Action Plan, was endorsed by Rio Tinto Limited and Rio Tinto plc shareholders, with 84% of the votes validly cast on the resolution across the joint electorate voted in favour of that resolution. The Climate Action Plan puts the low-carbon transition at the heart of Rio Tinto’s business strategy: combining investments in commodities that enable the energy transition with actions to decarbonise the company’s operations and value chains. The results of the Rio Tinto plc polls were certified by the scrutineer, Computershare Investor Services PLC, and the results of the Rio Tinto Limited polls were as reported by the duly appointed returning officer, a representative of Computershare Investor Services Pty Limited. These results are as set out below. Information on the final proxy position for each company is detailed in Appendix 1, and the votes cast on each resolution as a percentage of the issued capital of each company is set out on our website at www.riotinto.com/invest/shareholder-information/annual-general-meetings.

This places Chinalco close to the 14.99% holding threshold agreed with the Australian Government at the time of its original investment in Rio Tinto.

Notice to ASX/LSE Page 5 of 12 Appendix 1 FINAL PROXY POSITION Shareholders are encouraged to look at the voting figures provided in the main part of this announcement, as proxy figures may not be an accurate indication of the voting at the annual general meetings; a proxy is an authority or direction to the proxy holder to vote and not a vote itself. As such, the proxy figures do not reflect the votes cast by shareholders who attend the meeting in person, or through an attorney or corporate representative. References in this appendix in respect of Resolutions 1-17 and Resolutions 22 in the Rio Tinto plc notice of meeting and the corresponding Resolution 19 in the Rio Tinto Limited notice of meeting, to an appointment specifying that a proxy abstain on a resolution should, when referring to voting at Rio Tinto plc’s annual general meeting, be taken as references to the appointment specifying that the proxy withhold from voting on a resolution. The proxy position for each company (excluding the proxy votes carried from one meeting to the other meeting by the Special Voting Shares in accordance with the DLC structure) on the resolutions put to both Rio Tinto plc and Rio Tinto Limited shareholders under the joint electoral procedure was as follows: PROXY POSITION FOR RIO TINTO PLC AND RIO TINTO LIMITED ON JOINT DECISIONS Rio Tinto plc Rio Tinto Limited 1.
