Rio Tinto to acquire Chilean exploration assets and enter joint venture with Codelco

01 August 2023

Rio Tinto has agreed to purchase PanAmerican Silver’s stake in Agua de la Falda S.A. (“Agua de la Falda”), a company with exploration tenements in Chile’s prospective Atacama region, and to enter a joint venture with Corporación Nacional del Cobre de Chile (“Codelco”) to explore and potentially develop Agua de la Falda's assets.

Under the agreement, Rio Tinto will acquire PanAmerican Silver’s 57.74% operating stake in Agua de la Falda for $45 million and the grant of net smelter returns royalties. Rio Tinto will also acquire 100% of nearby concessions known as the Meridian Property for $550,000 and the grant of net smelter returns royalties.

Codelco, which is the world’s largest copper producer and is owned by the Chilean State, holds the remaining 42.26% of Agua de la Falda.

Rio Tinto Chief Executive Jakob Stausholm said “Copper is critical for the global energy transition, which is at the heart of Rio Tinto’s strategy, and Chile is one of the most important sources of world supply as demand for copper in renewables and electrification grows.

“Partnerships are essential to find better ways to provide materials the world needs, and we are pleased we can bring our global exploration capability to a joint venture that will be able to access Codelco’s strong local presence and industry expertise.

“Although this is an early-stage exploration project, we are very excited to be actively exploring in Chile in partnership with Codelco.”

Codelco Chairman Maximo Pacheco said “Codelco welcomes Rio Tinto in Agua de la Falda. This is a remarkable opportunity to put two leading mining companies to work together, leveraging the combined experiences, strengths, and capabilities of each organisation. By joining forces, we can enhance our exploration and development efforts for a highly promising asset.

“Public-private partnerships have proven to be successful for Codelco and Chile for many years, and we are convinced that this is a compelling alternative to move a project forward and to complement the significant exploration and project portfolio being developed exclusively by Codelco.”

The joint venture builds on an underground mining collaboration agreement between Rio Tinto and Codelco signed on 12 October 2022, aimed at encouraging innovations and technology to improve safety, productivity and environmental, social and governance (ESG) outcomes.

Agua de la Falda has previously been explored for precious metals with minimal modern exploration for copper. Analysis by Rio Tinto Exploration indicates it is prospective for new copper discoveries, which will now be the focus of the joint venture.

Rio Tinto releases interactive map of tailings facilities in alignment with GISTM requirements

04 August 2023

Rio Tinto has today disclosed detailed information on 14 of its global tailings facilities and their progress towards conformance with the Global Industry Standard on Tailings Management (GISTM).

These tailings facilities are those rated Very High or Extreme under GISTM classifications, based on the highest potential consequences in the extremely unlikely event of a failure.

Rio Tinto Chief Technology Officer Mark Davies said "Since the tragic failure of the tailings facility at Brumadinho in Brazil in 2019, the entire industry has been working to improve the way we manage tailings facilities.

"Responsible tailings management is critical to ensure the safety of our people and communities and to protect the environment. It is fundamental for our business and social license. We have made considerable progress since August 2020 towards conformance with the GISTM. We have completed most of the work and have detailed plans to complete outstanding items.

“GISTM has meant a step change in how the industry manages its tailings facilities. Good tailings management is also about transparent partnership, and we have been working with the local communities near our facilities to increase awareness of our management practices and how we can best work together to continue to keep people and the environment safe from harm.”

Details of these facilities and their progress in implementing the requirements of the GISTM can be accessed via an interactive map available at http://www.riotinto.com/tailings.

EXHIBIT 99.6 Media Release Rio Tinto and H2 Green Steel partner to accelerate the green steel transition 9 August 2023 LONDON – Rio Tinto and H2 Green Steel, an industrial startup establishing large scale production of green steel, have signed a multi-year supply agreement for high grade direct reduction iron ore pellets from Rio Tinto’s Iron Ore Company of Canada (IOC) operations. Rio Tinto will also purchase and on-sell a part of the surplus low carbon hot briquetted iron (HBI) produced by H2 Green Steel during the ramp-up of its steelmaking capacity. IOC’s direct reduction pellets will account for a significant part of the iron ore supply to H2 Green Steel’s flagship plant in Boden, Sweden, which will be one of the world’s first large-scale producers of low carbon iron and steel. The fully integrated, digitalised, and circular plant is expected to start operations in 2025, processing direct reduction pellets into HBI and then making steel through electric arc furnaces using green hydrogen. The Boden site will hold one of the world’s largest electrolysis plants for green hydrogen production. The production of steel, a key material for infrastructure and net-zero energy transition, currently contributes around 8% of global carbon emissions. By using green hydrogen in electric arc furnaces instead of coal in traditional steelmaking with a blast furnace, CO2 emissions can be reduced by up to 95 percent. H2 Green Steel Chief Executive Officer Henrik Henriksson said: “This is a significant milestone for our project in Boden. Not only by securing a supply of the high-quality iron ore needed for our green steel production, but also because we have a buyer for a portion of the HBI we initially expect to produce. Rio Tinto is a global leader in the mining industry and we welcome its concrete actions to accelerate the decarbonisation of the steel industry.” Rio Tinto Head of Steel Decarbonisation Simon Farry said: “We are partnering across the steel ecosystem to find better ways to support the decarbonisation of iron and steel making, and to reduce our scope 3 emissions. Our supply of high-grade iron ore pellets will support the acceleration of H2 Green Steel’s project, and on-selling their low-carbon HBI will enable us to gain a deeper understanding of the future needs of our customers and end users in the emerging green iron and steel market.”

EXHIBIT 99.7 Media Release Rio Tinto to build the largest solar power plant in Canada’s North 10 August 2023 YELLOWKNIFE, Canada – Rio Tinto’s Diavik Diamond Mine will build the largest solar power plant across Canada’s territories, featuring over 6,600 solar panels that will generate approximately 4,200 megawatt- hours of carbon-free electricity annually for the mine. The solar power plant will provide up to 25% of Diavik’s electricity during closure work that will run until 2029, with commercial production from the operation expected to end in early 2026. The facility will be equipped with bi-facial panels which will not only generate energy from direct sunlight, but also from the light that reflects off the snow that covers Diavik for most of the year. It will cut diesel consumption at the site by approximately one million liters per year and reduce emissions by 2,900 tonnes of CO2 equivalent, which is comparable to eliminating the emissions of 630 cars. President and Chief Operating Officer of the Diavik Diamond Mine Angela Bigg said: “I am delighted that we will be significantly increasing our renewable power generation with the largest solar power plant in Canada’s northern territories at the Diavik Diamond Mine. Through its wind-diesel hybrid power facility, Diavik is already a leader in cold climate renewable technology and this important project reinforces our dedication to reducing our carbon footprint. I would like to thank both the Government of the Northwest Territories and the Government of Canada for their support to deploy this project.” The solar power plant will significantly expand Diavik’s renewable energy generation, which already features a wind-diesel hybrid power facility that has a capacity of 55.4 MW and provides the site’s electricity. The project is supported by CAN$3.3 million in funding from the Government of the Northwest Territories’ Large Emitters GHG Reducing Investment Grant program, and CAN$600,000 from the Government of Canada’s Clean Electricity Investment Tax Credit. Government of the Northwest Territories Finance Minister Caroline Wawzonek said: “The Diavik solar power plant is a welcome sign of Rio Tinto’s commitment to renewable energy and reducing emissions. The Government of the Northwest Territories is pleased to have provided support through the Large Emitters GHG Reducing Investment Grant program, one of the original pieces of our made-in-the-NWT approach to the federal carbon tax. This collaboration exemplifies our commitment to facilitating sustainable development while reducing greenhouse gas emissions in the Northwest Territories and should be a signal of how our economic development can continue to position us as leaders in these spaces.” Diavik is working with the Government of the Northwest Territories and community partners to determine how its renewable energy infrastructure can best benefit the region following closure. Rio Tinto is progressing decarbonisation initiatives across its global operations, with the aim of reducing its Scope 1 and 2 greenhouse gas (GHG) emissions by 50% by 2030 and to achieve net zero across its operations by 2050.

Media Release 2 / 3 Construction will start in coming weeks and the solar power plant will be fully operational in the first half of 2024. Notes to editors The Diavik mine, 100 percent owned and operated by Rio Tinto, is Canada’s largest diamond producer and produces 3.5 to 4.5 million carats of rough diamonds per annum. Since mining began in 2003 Diavik has produced over 100 million carats of diamonds. Commercial production is expected to end in the first quarter of 2026. Under the Large Emitter Greenhouse Gas Reducing Investment Grant Program, the GNWT set aside twelve per cent (12%) of the total carbon tax paid by a prescribed large emitter during a fiscal year and makes the fund available to that emitter for projects that contribute to a reduction of greenhouse gas emissions in the Northwest Territories. The Diavik Solar Power Plant is the first project to be funded by the Large Emitter Greenhouse Gas Reducing Investment Grant Program.

EXHIBIT 99.8 Notice to ASX/LSE Agreements reached on trans-Guinean infrastructure in milestone for Simandou iron ore project 11 August 2023 Rio Tinto and the Simfer1 joint venture (Simfer) reached an important milestone today by concluding key agreements with the Republic of Guinea and Winning Consortium Simandou2 (WCS) on the trans-Guinean infrastructure for the world class Simandou iron ore project. The Co-Development Convention with the Republic of Guinea and associated agreements adjusting Simfer and WCS’s existing mine conventions create the legal framework for the co-development of more than 600 kilometres of new multi-use rail together with port facilities, that will be used to export iron ore from the Simandou mining concessions in the southeast of the country. Rio Tinto Executive Committee lead for Guinea and Copper Chief Executive Bold Baatar said “With these agreements we have reached an important milestone towards full sanction of the Simandou project, bringing together the complementary strengths and expertise of Rio Tinto and our partners, the Government of Guinea and Winning Consortium Simandou, for the infrastructure that will unlock this world class resource. Simandou, the world’s largest known undeveloped supply of high-grade, low-impurity iron ore, will strengthen Rio Tinto’s portfolio by complementing our existing Pilbara and Iron Ore Company of Canada products.” The infrastructure capacity and associated cost will be shared equally between Simfer, which is developing blocks 3 and 4 of the Simandou project, and WCS, which is developing blocks 1 and 2. China Baowu Steel Group has also previously entered into a term sheet agreement with WCS that may see it partner in the WCS scope for blocks 1 and 2 of the Simandou mining concession and the infrastructure joint venture. The Co-Development Convention requires ratification by the Guinean State. It is also subject to a number of conditions, including the Guinean State’s approval of the final feasibility study for the project. Negotiations continue between the partners to finalise the investment agreements and related shareholders’ agreements which underpin the co-development. A further announcement will be made when appropriate concerning these agreements.

Rio Tinto and Government of Madagascar reach agreement supporting the long-term operation of QMM

23 August 2023

Rio Tinto and the Government of Madagascar have reached agreement on the future fiscal arrangements for QIT Madagascar Minerals (QMM) and renewed their long-term partnership for the sustainable operation of the QMM mine in Fort Dauphin, Madagascar.

The new agreement was confirmed by the High Constitutional Court of Madagascar on 8 August 2023 and signed by the parties on 22 August 2023.

It will enhance the benefits received by the people of Madagascar and support a sustainable future for the QMM mine, providing certainty for Rio Tinto on the fiscal arrangements.

Under the terms of the agreement, there will be an increase in the royalty rate from 2% to 2.5% and QMM will issue its first dividend to the Government of Madagascar in 2023. An amount equalling the US$12 million dividend will be invested by the Government in the 109-kilometre rehabilitation project of the National Road 13 (RN13). Rio Tinto will also contribute up to US$8 million to the road project, subject to predefined milestones and deadlines. The project will bring significant improvement to the region by facilitating the movement of people and critical supplies to hard-to-access areas.

Rio Tinto has agreed to cancel US$77 million in advances made to the Government of Madagascar to finance their funding of QMM. The State will now hold a 15% free carry ownership of QMM and maintain its 20% voting right, with no obligation to contribute to capital funding or exposure to dilution.

QMM will also increase support for local communities by doubling its annual contribution to fund programs of interest.

Rio Tinto Iron and Titanium Managing Director, Sophie Bergeron said “Rio Tinto is committed to the responsible development of its mineral sands extraction business in Madagascar. This agreement is a significant milestone to support a long-term future for QMM and reaffirms our commitment to provide increased benefits for all parties, including the communities of Madagascar. We are privileged and honoured to be operating in Madagascar and we thank the country and its people for their trust.”

In 1998, Rio Tinto and the Government of Madagascar signed the Convention d’établissement (Framework Agreement), which has provided the foundation for Rio Tinto’s US$1 billion investment in QMM over the last 25 years. Whilst the Framework Agreement remains in place for the duration of QMM’s mining activities, the fiscal component was subject to renegotiation after 25 years.

EXHIBIT 99.16 Notice to ASX/LSE Rio Tinto and First Quantum complete La Granja joint venture transaction 28 August 2023 Rio Tinto and First Quantum Minerals ("First Quantum") have completed a transaction to form a joint venture that will work to unlock the development of the La Granja project in Peru, one of the largest undeveloped copper deposits in the world. La Granja is a complex orebody located at high altitude in Cajamarca, Northern Peru, that has the potential to be a large, long-life operation, with a published Indicated and Inferred Mineral Resource totalling 4.32 billion tonnes at 0.51% copper1. Following the completion of conditions including regulatory approvals from the Government of Peru, First Quantum has acquired a 55% stake in the project for $105 million. It will invest up to a further $546 million into the joint venture to sole fund capital and operational costs to take the project through a feasibility study and toward development. Upon completion of the sole funding commitment, all subsequent expenditures will be applied on a pro-rata basis according to the share ownership of the project. As majority owner, First Quantum will now operate the La Granja project with initial work focussed on completing the feasibility study, as per the Transfer Agreement signed with the Government of Peru. Rio Tinto Copper Chief Executive Bold Baatar said: “Developing La Granja would provide a significant new supply of copper and further strengthen Rio Tinto’s portfolio of materials needed for the energy transition. Our partnership with First Quantum will bring our combined development capabilities and deep knowledge of La Granja to progress the project.” First Quantum Chief Executive Officer Tristan Pascall said: “La Granja has the potential to be a large, long- life operation and supply the copper that will be needed as the world transitions to the greener economy and where responsible mining will be the only acceptable way to produce metals. As operator, we will leverage our core strengths in mine design, project development and community engagement and look forward to developing our partnership with Rio Tinto. We appreciate the support from the Government of Peru for the completion of this transaction.” Rio Tinto acquired the La Granja Project from the Government of Peru in 2006 and carried out an extensive drilling programme that significantly expanded the declared resource and understanding of the orebody, and established partnerships with host communities, local and national governments. 1 The Mineral Resources referred to in this release comprise 130 Mt at 0.85% Cu Indicated Mineral Resources and 4,190 Mt at 0.50% Cu Inferred Mineral Resources. These Mineral Resources were reported in Rio Tinto’s 2022 Annual Report released on 22 February 2023, which is available at Annual Report (riotinto.com). The Competent Person responsible for reporting these Mineral Resources is Joanna Marshall, a Member of the Australasian Institute of Mining and Metallurgy (MAusIMM). Rio Tinto is not aware of any new information or data that materially affects these Mineral Resource estimates and confirms that all material assumptions and technical parameters underpinning the estimates continue to apply and have not materially changed. The company confirms that the form and context in which the Competent Person’s findings are presented have not been materially modified. Mineral Resources are quoted in this release on a 100 per cent basis.
