EX-99.2

Notice to ASX/LSE 1 September 2022 Rio Tinto and Turquoise Hill reach agreement in principle for Rio Tinto to acquire full ownership of Turquoise Hill for C$43 per share in cash Rio Tinto and Turquoise Hill Resources Ltd. (“Turquoise Hill”) have reached an agreement in principle for Rio Tinto to acquire the approximately 49% of the issued and outstanding common shares of Turquoise Hill that Rio Tinto does not currently own for C$43 per share in cash (the “Transaction”). The agreement has the unanimous approval of the independent Special Committee of Turquoise Hill’s Board of Directors (the “Special Committee”), and values the Turquoise Hill minority share capital at approximately US$3.3 billion. The purchase price of C$43 per share in cash represents Rio Tinto’s best and final offer and a premium of: • 67% to Turquoise Hill’s closing price of C$25.68 per share on 11 March 2022, being the day prior to Rio Tinto’s initial public non-binding proposal to acquire Turquoise Hill; and • 125% to Turquoise Hill’s closing price of C$19.12 per share on 24 January 2022, being the day before agreeing on a path forward between the Government of Mongolia, Turquoise Hill and Rio Tinto that enabled commencement of the underground mine at Oyu Tolgoi (“OT”). The Transaction is to be implemented by way of a plan of arrangement under the Business Corporations Act (Yukon) and both companies intend to expeditiously finalise an arrangement agreement (the “Arrangement Agreement”). An announcement will be made with details of the Arrangement Agreement once executed. The Transaction will require the approval of 66.67% of votes cast by shareholders of Turquoise Hill (including Rio Tinto) and the approval of a simple majority of the votes cast by minority shareholders of Turquoise Hill. A special meeting of shareholders of Turquoise Hill to approve the Transaction is expected as early as possible in the fourth quarter of 2022 and, if approved, the Transaction is expected to close shortly thereafter. Rio Tinto and Turquoise Hill have also agreed in principle to the following amendments to the financing Heads of Agreement (“HoA”), to become effective concurrently with the execution of the Arrangement Agreement, to support Turquoise Hill in addressing near term liquidity: • Increasing the early advance facility agreed in May to US$650 million from US$400 million, provided that if there is an anticipated funding shortfall for March 2023 the parties will in good faith discuss increasing the early advance facility by up to an additional US$100 million; • Extending the outside date by which the initial equity of US$650 million must be raised and early advance facility repaid from 31 December 2022 to 31 March 2023 and potentially to 31 May 2023 in the event of regulatory delays to the Arrangement Agreement; • In the event the Transaction has not been approved when the December 2022 principal repayment obligation of US$362 million by Turquoise Hill under the OT project finance facility arises, Rio Tinto has committed to ensuring funds are available to Turquoise Hill. The funds for this payment would be made available on the same terms as the Early Advance and being repayable to Rio Tinto at the same time as the Initial Equity Offering; and • Providing to Turquoise Hill Rio Tinto’s commitment to participate pro rata in the Initial Equity Offering subject to certain pre-conditions set forth in the HoA. Rio Tinto Chief Executive Jakob Stausholm said: “Rio Tinto is committed to moving Oyu Tolgoi forward in direct partnership with the Government of Mongolia to realise its full potential for all stakeholders. This agreement represents another significant step following the recent commencement of the underground operations, and will simplify governance, improve efficiency and create greater certainty of funding for the long-term success of the Oyu Tolgoi project.” Rio Tinto Copper Chief Executive Bold Baatar said: “The transaction simplifies the ownership structure of Oyu Tolgoi and enables Rio Tinto to focus on working in partnership directly with Erdenes Oyu Tolgoi and the Government of Mongolia to create long-term value for all stakeholders. EXHIBIT 99.2

Notice to ASX/LSE Page 2 of 4 “Turquoise Hill minority shareholders will realise a significant and immediate cash premium for their shares at a time when uncertainties inherent in the development of the underground operations remain. Turquoise Hill will also avoid the issuance of any equity component as part of the US$3.6 billion incremental funding requirement through to the completion of the Oyu Tolgoi project. Securing the approval of the Special Committee to our agreement in principle, following extensive negotiations, was essential for Rio Tinto to progress this proposed transaction.” Advisors Credit Suisse, RBC Capital Markets and Rothschild & Co are acting as financial advisors to Rio Tinto, and McCarthy Tétrault LLP and Sullivan & Cromwell LLP are acting as legal advisors.

TD Securities has been retained by the Special Committee as an independent valuator in accordance with applicable securities laws.

EX-99.3

Notice to ASX/LSE 6 September 2022 Rio Tinto and Turquoise Hill enter into definitive arrangement agreement for Rio Tinto to acquire full ownership of Turquoise Hill Turquoise Hill Board of Directors unanimously recommends minority shareholders vote in favour of Rio Tinto’s best and final offer of C$43 per share in cash Rio Tinto has entered into a binding agreement (the “Arrangement Agreement”) to acquire all of the remaining shares of Turquoise Hill Resources Ltd (TSX: TRQ) (NYSE: TRQ) (“Turquoise Hill”) that Rio Tinto does not currently own (the “Transaction”). The Independent Directors of Turquoise Hill have unanimously recommended that Turquoise Hill minority shareholders vote in favour of the Transaction and, together with senior officers of Turquoise Hill, have entered into voting support agreements with respect to all of the Turquoise Hill shares they own or control. The Transaction delivers significant value to Turquoise Hill minority shareholders with the certainty of an all- cash offer of C$43 per share, which is Rio Tinto’s best and final offer. This represents a premium of 67% to Turquoise Hill’s closing price of C$25.68 per share on 11 March 2022, the day prior to Rio Tinto’s initial public proposal to acquire Turquoise Hill. Rio Tinto has agreed to provide Turquoise Hill with secured short-term liquidity during the Transaction period of up to US$1.1 billion (subject to certain pre-conditions), which would need to be repaid from an equity raising from shareholders in the first half of 2023 if the Transaction is not approved by shareholders. Turquoise Hill has estimated that it requires US$3.6 billion of additional funding in total to complete the project. It aims to address this through a funding plan including renegotiating debt repayment dates, which requires the unanimous consent of participating lenders. The success of this debt renegotiation and certain other funding plans is uncertain and, if unsuccessful, could require further equity contributions from shareholders. The Transaction delivers certainty for the financing needs of Oyu Tolgoi and alleviates any further funding risks for shareholders. Rio Tinto Chief Executive Jakob Stausholm said: “This Transaction will simplify governance, improve efficiency and create greater certainty of funding for the long-term success of the Oyu Tolgoi project. Rio Tinto’s offer guarantees Turquoise Hill’s minority shareholders outstanding value through a significant all- cash premium for their shares. After extensive negotiations, the terms of the transaction are final and there will be no further price increase. We look forward to working with the Turquoise Hill Board of Directors to ensure Turquoise Hill shareholders are able to realise the significant and immediate value of the Transaction.” Rio Tinto Copper Chief Executive Bold Baatar said: “Rio Tinto will work in direct partnership with the Government of Mongolia and Erdenes Oyu Tolgoi to realise the full potential of the Oyu Tolgoi project for the benefit of all stakeholders. This Transaction rewards all minority shareholders with an exceptional premium of 67% for their shares and brings the financial certainty necessary to ensure the Oyu Tolgoi project can be developed without having to ask minority shareholders to contribute further significant funds.” The Transaction will be implemented by way of a Canadian Plan of Arrangement and require the approval of 66.67% of votes cast by all shareholders of Turquoise Hill (including Rio Tinto) and the approval of a simple majority of the votes cast by minority shareholders of Turquoise Hill. A special meeting of shareholders of Turquoise Hill to approve the Transaction is expected as early as possible in the fourth quarter of 2022 and, if approved, the Transaction is expected to close shortly thereafter. Details of the Transaction and Arrangement Agreement will be provided in the management information circular to be mailed to Turquoise Hill shareholders. EXHIBIT 99.3

Rio Tinto and Volvo Group partner for low-carbon materials supply and pilot sustainable autonomous hauling solutions

13 September 2022

LONDON--(BUSINESS WIRE)-- Rio Tinto and Volvo Group have signed a Memorandum of Understanding (MoU) to create a strategic partnership where Rio will supply responsibly sourced low-carbon products and solutions to Volvo Group and the companies will work towards decarbonising Rio Tinto’s operations through piloting Volvo Group’s sustainable autonomous hauling solutions.

The multi-materials partnership will allow Rio Tinto, a leading global mining and metals company, to progress sustainability commitments in its operations and supply chains. It will support Volvo Group, one of the world’s largest transport and infrastructure providers, in its ambition towards a net-zero future. The partnership aims to secure supplies of materials including lithium, low-carbon aluminium, copper, and metallics.

Rio Tinto Chief Executive Jakob Stausholm said: “We look forward to partnering with Volvo to progress our contribution to a net-zero future, as we collaborate to deliver sustainable outcomes from the mine to the showroom floor. We will be working together to support the decarbonisation of Rio Tinto’s operations and deliver low-carbon materials for use in Volvo’s innovative product range, including electric and autonomous vehicles.”

Volvo President and Chief Executive Officer Martin Lundstedt said: “We are eager to partner with Rio Tinto, a true collaboration aiming to accelerate our ambitions towards a fossil-free, decarbonised future. By addressing the full value chain, from the use of low-carbon materials in our products, to providing our customers with sustainable autonomous hauling solutions, we can contribute to a better and more sustainable future.”

The companies will work together to strengthen the supply of responsibly sourced low-carbon materials such as RenewAlTM aluminium, aluminium produced using the ELYSISTM zero-carbon smelting technology, Aluminium Stewardship Initiative (ASI) certified aluminium and Copper Mark certified copper, and explore product development opportunities such as the supply of lithium for batteries.

Notes to editors

Volvo Autonomous Solutions

The autonomous hauling solution offered by Volvo Autonomous Solutions is based on Transport as a Service (TaaS) and includes a vehicle purpose-built for autonomous driving, a virtual driver, required infrastructure, operations and uptime support as well as a cloud solution that controls the transport system and manages logistics flows. The solutions developed by Volvo Autonomous Solutions are tailor-made for each customers’ needs and intended to make their operations more safe, productive and sustainable.

Rio Tinto

Rio Tinto is an industry leader in the supply of responsibly produced materials.

In 2016, Rio Tinto launched RenewAlTM, the world’s first certified low CO2 primary aluminium brand. It has helped to pioneer responsible production standards for the global industry as a founding member of the Aluminium Stewardship Initiative (ASI), becoming the first producer to offer ASI Aluminium in 2018.

ELYSIS is a technology company created through a partnership between aluminium industry leaders Rio Tinto and Alcoa, with support from Apple and the governments of Canada and Quebec. ELYSIS is scaling up a revolutionary technology that enables the production of metal without direct carbon dioxide emissions during the aluminium smelting process, instead emitting pure oxygen. The technology uses inert anodes to replace the carbon anodes traditionally used during electrolysis, the process used to make primary aluminium. Learn more at www.elysis.com.

In 2020, Rio Tinto’s Kennecott and Oyu Tolgoi operations became the first producers to be awarded the Copper Mark, the copper industry’s independent responsible production programme. To achieve the Copper Mark – developed according to the United Nations Sustainable Development Goals – Kennecott’s and Oyu Tolgoi’s copper was assessed against 32 criteria covering Environment, Community, Business and Human Rights, Labour and Working Conditions and Governance.

Rio Tinto joins First Movers Coalition to help drive low-carbon transition

20 September 2022

NEW YORK--(BUSINESS WIRE)-- Rio Tinto today announced it will join the First Movers Coalition, a global initiative to help commercialise zero-carbon technologies by harnessing purchasing power and supply chains.

More than 50 companies with a collective market value of about $8.5 trillion across five continents now make up the coalition to create early markets for innovative clean energy technologies.

The initiative is led by the World Economic Forum and the US Government and targets sectors including aluminium, aviation, chemicals, concrete, shipping, steel, and trucking, which are responsible for 30 per cent of global emissions. This is expected to rise to over 50 per cent by mid-century, unless there is urgent progress on clean technology innovation.

Rio Tinto Chief Commercial Officer Alf Barrios said: “We want to bring Rio Tinto’s considerable buying power to help build sustainable supply chains for emerging green technologies. The low-carbon transition is at the heart of our business strategy and success will require large scale of change throughout the value chain, which our pledges to the First Movers Coalition are aimed at supporting.

“As a member of the First Movers Coalition, we also look forward to building on our existing network of partnerships to support the development of new technologies to help power our way to a net-zero future.”

Head of the First Movers Coalition at the World Economic Forum Nancy Gillis said: “Rio Tinto’s commitment to a sustainable future makes the company an impactful addition to the First Movers Coalition. We look forward to collaborating with Rio Tinto to encourage clean energy innovation and transition the mining industry toward a zero-carbon future.”

Rio Tinto is making commitments to purchase more zero emissions fuel for its own shipping fleet and make greater use of suppliers who use zero emission fuels in shipping and aviation. It has also pledged that it will ensure a greater proportion of heavy haul trucks it acquires will be zero emissions.

The company is working to reach net zero by 2050. It has set a target of a 50% reduction in Scope 1 and 2 emissions by 2030, backed with an estimated investment of approximately $7.5 billion in capital.

For more information about the First Movers Coalition visit www.weforum.org.

Notes to editors

Rio Tinto is a leading supplier of high quality, low-carbon footprint aluminium, including the use of renewable hydropower, and is working to reduce emissions even further. We are scaling up a revolutionary technology for zero-carbon aluminium smelting technology through our ELYSIS partnership with Alcoa, with support from Apple and the governments of Canada and Quebec. In Australia, we aim to develop green repowering solutions for the Boyne Island and Tomago smelters, and are working with the state and federal governments, power companies and renewable developers to increase the availability of renewables.

Rio Tinto has entered the First Movers Coalition’s shipping, trucking and aviation categories, where general commitments for participants include:

Shipping

•Ship Owner: “At least 5% of our deep-sea shipping will be powered by zero-emission fuels by 2030, enabled by ships capable of using zero-emission fuels”

•Cargo Owner: “At least 10% of the volume of our goods shipped internationally will be on ships using zero-emission fuels by 2030; on the way to 100% by 2040”

Trucking

•Trucking Owner / Operator: “At least 30% of my heavy-duty and 100% of my medium-duty new truck purchases will be zero-emission trucks by 2030”

•Trucking Services User: “I require my trucking service providers to meet the commitment that at least 30% of heavy-duty and 100% of medium-duty new truck purchases will be zero-emission trucks by 2030”

Aviation

•Airfare Purchaser: “By 2030, we will partner with air transport operators to replace at least 5% of conventional jet fuel used for our air travel/freight with sustainable aviation fuels (SAF) that reduce lifecycle GHG emissions by 85% or more when compared with conventional jet fuel, and/or using zero-carbon emitting propulsion technologies”

Rio Tinto is working closely with the FMC team to determine how it practically integrates the intent of the commitments in the context of Rio Tinto’s global operations.

Notice to ASX/LSE 27 September 2022 Rio Tinto to start underground mining at Kennecott copper operations Rio Tinto has approved a $55 million1 investment in development capital to start underground mining and expand production at its Kennecott copper operations in Utah, United States. Underground mining will initially focus on an area known as the Lower Commercial Skarn (LCS), which will deliver a total of around 30kt2 of additional high quality mined copper through the period to 2027 alongside open cut operations. The first ore is expected to be produced in early 2023, with full production in the second half of the year. It will be processed through the existing facilities at Kennecott, one of only two operating copper smelters in the United States. Kennecott holds the potential for significant and attractive underground development. The LCS is the first step towards this, with a Mineral Resource of 7.5 Mt at 1.9% copper, 0.84 g/t gold, 11.26 g/t silver, and 0.015% molybdenum identified based on drilling and a Probable Ore Reserve of 1.7 Mt at 1.9% copper, 0.71 g/t gold, 10.07 g/t silver, and 0.044% molybdenum3. Underground battery electric vehicles are currently being trialed at Kennecott to improve employee health and safety, increase productivity and reduce carbon emissions from future underground mining fleets. A battery electric haul truck and loader supplied by Sandvik Mining and Rock Solutions are being used to evaluate performance and suitability as part of underground development work. Rio Tinto Copper chief executive Bold Baatar said, “This investment will allow us to quickly bring additional volumes of high quality copper to the market and build our knowledge and capabilities as we evaluate larger scale underground mining at Kennecott. We are progressing a range of options for a significant resource that is yet to be developed at Kennecott, which could extend our supply of copper and other critical materials needed for electric vehicles and renewable power technologies.” “Trialling underground battery electric vehicles is an exciting step in our work to create a safer workplace for our employees, increase the productivity of the mine and reduce emissions from our operations. We look forward to seeing their potential for deployment.” Existing undergound infrastructure is currently being extended to enable early access to the next underground resource and undertake characterisation studies. A Feasibility Study to inform decisions on the next phase of underground production is expected to be completed in 2023. This will be one of several potential stages currently being investigated. Feasibility studies are also being progressed to extend open pit mining at Kennecott beyond 2032. The Table 1 Release was made in accordance with the JORC Code and the ASX Listing Rules.

Summary of information to support the Mineral Resource reporting The Rio Tinto Kennecott Lower Commercial Skarn Mineral Resources are supported by the information set out in the Appendix to this release and located at riotinto.com/financial-news-performance/resources-and- reserves in accordance with the Table 1 checklist in the JORC Code. The following summary information is provided in accordance with rule 5.8 of the ASX Listing Rules. This declaration of initial Mineral Resources follows completion of orebody knowledge drilling in the Lower Commercial Skarn (LCS) deposit and a feasibility study. Geology and geological interpretation The LCS deposit is located in the Bingham mining district southwest of Salt Lake City, Utah (see Figure 1). The Bingham mining district is dominated by the Bingham Canyon copper-molybdenum-gold porphyry system, which consists of the Eocene monzonite-quartz monzonite Bingham Stock and deformed siliciclastic and carbonate country rock of the Paleozoic Bingham Mine Formation. The LCS deposit is hosted in mineralized skarn of the Lower Commercial Limestone (LCLS) unit of the Lower Bingham Mine Formation. This unit is proximal to the Bingham Canyon porphyry system and has been altered to copper-gold hosting calc-silicate skarn through prograde metasomatism with localized retrograde massive sulphide and clay. This unit has been variably folded and faulted prior to mineralization, resulting in fold thickening and repetition of the units across faults. Drilling, sampling, sub-sampling method and sample analysis method The LCS deposit is defined by 73 diamond drill holes, consisting of 37 pre-existing surface and underground holes, drilled between 1964 and 2012; 25 underground holes drilled during prefeasibility studies in 2015 and 2016; and 11 holes drilled in 2017 and 2018 to support feasibility studies (see Figure 2). The recent (2015 to 2017) prefeasibility through feasibility study drilling program totals 36 holes and 6,690 m of HQ coring, utilizing comprehensive geoscientific core logging, select downhole acoustic borehole imaging, geomechanical testing, hydrogeologic measurement, and geochemical assay to inform geologic interpretation, geotechnical characterization, and resource estimation. Final nominal drill hole spacing in the entire LCS deposit is less than 46 m for approximately half of the Mineral Resource (Indicated), with much of it drilled to less than 23 m (Measured), with the remaining resource at a nominal spacing of 91 m (Inferred). Drill core is sampled on 3 m intervals for assay by default, unless notable geologic character defines a smaller or slightly larger interval. Typical sample intervals during the 2015 to 2017 prefeasibility through feasibility study drilling programs averaged 2.7 m. The prefeasibility through feasibility study drilling and sampling programs generated over 1,900 individual assay samples in the LCS deposit, with over 5,180 m of core assayed. Core assayed prior to 1990 were assayed by Kennecott’s internal laboratories, following this all assays were completed by outside laboratories with documented internal and external quality assurance and quality control (QA/QC) procedures maintained to present. Assays and their origin laboratory are stored in the Rio Tinto acQuire™ database. Original assay certificates are stored on Rio Tinto network servers. Bingham Canyon assay sample QA/QC procedures established in 1990 apply to all holes following 1990 as follows: • Duplicate samples are generated from the remaining half core every 40th sample. • Duplicate samples are generated from the crushed duplicate material every 20th sample. • Matrix matched pulp standards are inserted every 20th sample. • Five percent of pulps are randomly selected for assay validation at a second lab. Given the short hole lengths and focused targeting for the 2015 to 2017 drilling programs, the automatic footage-based creation and insertion of duplicates and standards was replaced with the following manual process: • One to three core sample duplicates are manually selected from the target zone in each hole. • One to three crushed sample duplicates are manually selected from the target zone in each hole. • One to three matrix-matched pulp standards are inserted for manually selected sample intervals from the target zone in each hole. • One sample blank is inserted in each hole.

Page 4 of 18 Results for duplicates and standards are checked, flagged, retested, or resampled if deemed necessary, and stored via automated reporting from the acQuire™ database, providing confidence in the accuracy of the sampling and assaying procedures, with fit-for-purpose precision on the assay values. Estimation methodology The block model designed for grade interpolation has block dimensions of 4.5 m x 4.5 m x 3 m, to reflect the granularity and precision of the wireframe geologic model. Samples are composited at 3 m intervals, breaking on lithological boundaries. Composite length matches the granularity of the block model, the maximum assay size and the general observed grade and geological variation downhole. Detailed statistical analysis, exploratory data analysis (EDA), is completed for all economic and deleterious variables. Box plot analyses are completed for all estimated variables with a breakdown by lithology. Contact plots are completed for silver (Ag), gold (Au), copper (Cu) and molybdenum (Mo), to determine boundary conditions and univariate statistics compiled and evaluated for similarities Variography is completed for all domains by estimation variable. This process includes omni-directional variography to establish continuity exists and constrain short range continuity (i.e., nugget) followed by directional analysis. Ordinary Kriging (OK) and inverse distance were compared as options for interpolation, with OK selected as the primary interpolation method for all variables (aside from density) for its statistically robust reflection of grade trends, especially in areas of dense data (e.g., near drill collars). Estimation is performed by nested searches (four progressively larger ellipses tied to percentages of each domain’s variogram sill) for all variables. Density is estimated by Simple Kriging in a single pass for the skarn lithology domain; all other lithologies are assigned a single density value by script due to their low variance. A series of models were completed to establish centrality of the estimate. This analysis is meant to quantify the changes to the resource estimate with each incremental change in the model (i.e., addition of new drilling and geological interpretation through to estimation). Sixteen (16) models were completed and compared in total, with seven (7) of these compared post-final estimation, to determine the variance and sensitivity of the final model. Cut-off grades and modifying factors Cut-off grade for Mineral Resources is determined on a Net Smelter Return basis for total contained metal and recoveries through the Rio Tinto Kennecott concentrator, smelter, and refinery, with associated processing and handling costs. Metal prices for Cu, Au, Ag, and Mo are provided by the Rio Tinto Economics team, using internal analyses and projections. Recovery values are developed from the established performance of the Rio Tinto Kennecott processing plants and targeted metallurgical testing completed during prefeasibility and feasibility studies. Processing and handling costs are developed from demonstrated internal cost performance. All material above cut-off is considered to have reasonable prospects for eventual economic extraction. Criteria used for Mineral Resource classification Resource classification in the LCS deposit is based on the geologic continuity of the stratigraphically and structurally controlled host unit and waste units, with nominal drill spacings as follows: Inferred Resource • Nominal 91 m spacing • Manually wireframed to exclude isolated blocks and target potentially minable volumes Indicated Resource • Nominal 46 m spacing • Manually wireframed to exclude lower confidence geologic domains • Manually wireframed to exclude isolated blocks and target potentially mineable volumes Measured Resource • Nominal 23 m spacing • Manually wireframed to exclude isolated blocks and target potentially mineable volumes

Page 5 of 18 Summary of information to support the Ore Reserve reporting The addition of the Ore Reserve estimate for the LCS is based on the Mineral Resource model for the deposit along with the feasibility study completed in 2018. A recent in-depth internal review of geotechnical, mine design and cost estimating parameters has been completed to refresh project conclusions. The economic cut- off methodology has been developed in order to maximise value within the deposit while reducing risk. Ore Reserves are supported by the information set out in the Appendix to this release and located at riotinto.com/financial-news-performance/resources-and-reserves in accordance with the Table 1 checklist in the JORC Code. The following summary information is provided in accordance with rule 5.9 of the ASX Listing Rules. Cut-off grades, mining method and modifying factors The Ore Reserve cut-off is based on a Net Smelter Return (NSR) calculation which considers pricing, recoveries and costs. The $90 NSR cut-off value selected for use with the estimate was based on optimising the overall value of the deposit. The cut-off value was determined based on an iterative approach to determine the optimum value to the deposit. An additional selection criterion was applied to exclude high risk stopes in areas of the mineralization where rock quality is modelled as poor, or where they come too close to existing infrastructure. The LCS estimate is based on a sub-level, long hole open stoping mining method, using a primary secondary sequence with cemented aggregate backfill. Detailed geotechnical analysis has informed the mining method and mining dimensions using information gained from resource drilling. Modifying factors have been applied to the estimate, the first being a stope shape factor (92.5%) to deduct areas of the stope which cannot be practically drilled such as the stope “shoulders”. External waste dilution (10% for secondaries, 2.5% for primaries) has been applied to the estimate at zero grade based on an evaluation of the geotechnical parameters with established industry empirical dilution guidelines. Finally, a mining recovery factor (90%) to account for drilled and blasted material or dilution which cannot be extracted from the stope. All these factors have been established as part of the feasibility study. There are no material impacts from other Ore Reserve modifying factors, such as: governmental, tenure, environmental, cultural heritage, social or community. Appropriate agreements and approvals are in place to enable operation of the assets. Processing methods and assumptions Underground ore from the LCS will be processed through the existing Kennecott facilities established as part of the open pit operation. Expected metal recovery and quality from downstream processing has been assessed through laboratory scale test work of samples generated from resource drilling, and the response of this material when blended with open pit ore. Economic assumptions and study outcomes Incremental cash flow is generated due to the addition of LCS ore to the open pit feed. This includes consideration of revenue generated from low-grade ore from underground which is above the open pit cut-off, deductions for material rehandling, pit ore deferral, and deleterious elements. Rio Tinto applies a common process to the generation of commodity price assumptions across the group. This involves generation of long-term price forecasts based on current sales contracts, industry capacity analysis, global commodity consumption and economic growth trends (this includes the bonus / penalty adjustments for quality). Exchange rates are also based on internal Rio Tinto modelling of expected future country exchange rates. Due to the commercial sensitivity of these assumptions, an explanation of the methodology used to determine these assumptions has been provided, rather than the actual figures. Criteria used for Ore Reserve classification Given the lack of recently demonstrated stope performance, established stope costs, or underground operation in a production environment, all Measured and Indicated Resources within the Ore Reserve boundaries were converted to Probable Ore Reserves. Any Inferred Mineral Resources within the Ore Reserve boundaries have been included within the Probable Ore Reserve tonnage as dilution with zero grade.

Page 10 of 18 Appendix Lower Commercial Skarn JORC Table 1 The following table provides a summary of important assessment and reporting criteria used at Lower Commercial Skarn for the reporting of Mineral Resources and Ore Reserves in accordance with the Table 1 checklist in The Australasian Code for the Reporting of Exploration Results, Mineral Resources and Ore Reserves (The JORC Code, 2012 Edition). Criteria in each section apply to all preceding and succeeding sections. Section 1: Sampling Techniques and Data Criteria Commentary Sampling techniques • Samples supporting resource estimation are taken from split diamond drill core of HQ and NQ diameters. • Samples are split from whole core on 3 m standard intervals, with smaller intervals as dictated by the logging geologist. • Half-core samples are sent for assay, with the other half remaining on site. Drilling techniques • Drilling techniques are standard diamond drill coring and wireline retrieval with standard NQ and HQ tubes from surface and underground. • All holes drilled since 2015 are cored using triple-tube techniques. Drill sample recovery • Core recovery is recorded as part of standard logging procedures. • Triple tube drilling techniques are used in contemporary drilling to preserve in-situ conditions. • Core recovery is typically greater than 80%. Logging • All core intersecting the deposit is logged for geologic character, including lithology, alteration, mineralogy, veining, and structure. • Geotechnical logging is completed for RQD and Q. Sub-sampling techniques and sample preparation • Core is manually sawn into halves according to intervals selected by the logging geologist, with care taken to split mineralization equally. • Core duplicate samples are created using the remaining half-core, at intervals specified by the logging geologist, with one to three core duplicate samples per orebody intercept. • Samples are prepared and assayed by an external laboratory, where they are crushed, then split and pulverized into four pulps. The crushed sample reject material is returned to Rio Tinto Kennecott. • Pulps are assayed for Au, Cu, Mo, Ag, and a suite of other elements. • Sampling procedures have been reviewed and audited by external sample experts, most recently in 2010 (AMEC), with no material findings. Quality of assay data and laboratory tests • Cu, Mo and Ag are assayed by HNO3-HClO4-HF-HCl digestion and ICP-AES analysis. Au is assayed by fire assay fusion with an AAS finish for one assay-ton. • Duplicate samples are generated from the crushed reject material and assayed at intervals specified by the logging geologist, with one to three duplicates per orebody intercept. • Matrix matched pulp standards are inserted at intervals specified by the logging geologist, with one to three standards per orebody intercept. • Blank sample material is inserted at intervals specified by the logging geologist, with one to three blanks per orebody intercept. • Current QA/QC procedures have been in place since 1990. The acQuire™ data management database system has been used since 2000. • Historic assays that have been tested by more than one lab are ranked, and the most appropriate assay stored as the primary assay. • QA/QC procedures provide confidence in the accuracy of the sampling and assaying procedures, with fit-for-purpose precision on the assay values. Verification of sampling and assaying • Results are evaluated for overall grade, performance of standards, blanks, core duplicates, and laboratory duplicates, and re-tested when out of specification. • Mineral Resource and Ore Reserves standard operating procedures (SOPs) document data handling, processing, storage, and validation. • There is no adjustment to drillhole assays. There is a laboratory ranking for samples assayed by more than one laboratory and the most appropriate assay is stored as the primary assay. Location of data points • Surface and underground drill hole collars are located using traditional survey instruments and techniques, or GPS survey. • With the exceptions of UD0004 and UD0005, all surface and underground downhole surveys since 2006 have been completed gyroscopically (47 holes). All others were surveyed magnetically (26 holes). Magnetic survey intervals (pre-2006) vary from 3 to 60 m typically. Gyroscopic survey intervals in surface holes (2006 to 2009) are typically 3 to 6 m. Gyroscopic survey intervals in targeted underground drilling since 2015 are 7.5 m.

Page 11 of 18 • Deviation in the current underground drill holes has been very minimal due to typically short hole lengths of 250 m or less, with very good geologic coherence between holes. Where rare disagreement between longer surface or historic holes and the current drilling is found, geologic interpretation and wireframes are controlled by the current drillholes. • Collar surveys for all holes are documented and are checked against pit geographic and underground as-built surveys. In the absence of misalignment between a collar and surface topography or underground as-built, all collars are assumed to be accurate. • All locations are referenced to the local Bingham Mine grid. Data spacing and distribution • Data spacing within the LCS orebody varies depending on location. • Underground drill holes occur at a variety of angles from flat to vertical. Surface drill holes are vertical. • Nominal drill hole spacing in the entire LCS deposit is less than 46 m for approximately half of the Mineral Resource (Indicated), with much of it drilled to less than 23 m (Measured), with the remaining resource at a nominal spacing of 91 m (Inferred). • Data spacing and grade continuity are directly assessed in the LCS Mineral Resource estimate and resulting Mineral Resource classification. • All assay data in the Mineral Resource estimate are composited to 3 m intervals. Orientation of data in relation to geological structure • Hole orientations vary between vertical, horizontal, and angled. • All drill holes pierce the full width of the tabular sub-horizontal orebody. • Angled and sub-horizontal drill holes provide good control of sub-vertical geologic structures such as the Verona fault and latite porphyry dikes. • Hole orientation introduces no material bias to the final Mineral Resource estimate. Sample security • Current sample security procedures include bolt seal chain of custody documentation tracking samples from the site to the lab. • Sample weights are cross checked between the site and the lab. • Half core and assay pulps are retained in a secure warehouse on site. Audits or reviews • A comprehensive external review of the LCS resource model was completed in 2017 by Amec Foster Wheeler, concluding that it is suitable for development of a sublevel open stope mine. Additional conclusions from this review include: o Drilling, sampling, and assaying procedures meet industry standards. o The database contains information on lithology, alteration, structure, and assays. This should be sufficient to support mine planning. o There is sufficient drilling to support feasibility-level mine designs, with spacings typical of those in use at other skarn-hosted deposits. o The geological interpretation honours the logging well. o Exploratory data analysis is carefully done and consisted of univariate statistics for metals by rock type, variography, contact analysis, and high-yield restriction on outliers. o The multi-pass estimation approach used is appropriate to a deposit with uneven drill spacing. The kriging plan chosen for the base case (BM 8) gives a slightly conservative result with contained copper reduction (approximately 3%) related to high-yield restriction of high-grades. Inspections of the model show slight over projection of +4% Cu zones. o The resource models for Cu, Au, Ag and Mo were validated using a nearest neighbour model. Global statistics and swath (drift) plots compare well. o The distribution of copper grade above cut-off is not highly skewed. Locally some stopes show an increase in grade with increased distance to the closest sample; elsewhere stopes can show no trend or a decrease in grade with increased distance to the closest sample. Section 2: Reporting of Exploration Results Criteria Commentary Mineral tenement and land tenure status • The LCS deposit is within the current operations of the Bingham Canyon Mine, owned and licenced to Rio Tinto Kennecott Copper (RTK’s legal name is Kennecott Utah Copper LLC). Kennecott Utah Copper LLC, is an indirect wholly owned subsidiary of Rio Tinto plc. Exploration done by other parties • Various companies since 1870 have worked around the core of the RTK holdings. As properties were acquired, exploration information was obtained and incorporated into the current database. • Since 2009, Rio Tinto Exploration has performed brownfield exploration in and near the deposit. Geology • The LCS deposit is located in the Bingham mining district southwest of Salt Lake City, Utah. The Bingham mining district is dominated by the Bingham Canyon copper-molybdenum-gold porphyry system, which consists of the Eocene monzonite-quartz monzonite Bingham Stock and deformed siliciclastic and carbonate country rock of the Palaeozoic Bingham Mine Formation. The LCS deposit is hosted in mineralized skarn of the Lower Commercial Limestone (LCLS) unit

Page 12 of 18 of the Lower Bingham Mine Formation. This unit is proximal to the Bingham Canyon porphyry system and has been altered to copper-gold hosting calc-silicate skarn through prograde metasomatism with localized retrograde massive sulphide and siderite. This unit has been variably folded and faulted prior to mineralization, resulting in fold thickening and repetition of the units across faults. • The LCS deposit lies in the footwall of the southwest dipping Midas thrust fault, between the older northeast striking and steeply dipping oblique transverse Verona and Smelter faults. This structural block between the Verona and Smelter faults, and below the Midas, is referred to as the Middle Block. The Middle Block is bounded to the south by the Bingham Canyon porphyry monzonite, open to the north, and cut by late latite porphyry dikes on a northeast trend. Palaeozoic country rock within the Middle Block is folded in an asymmetric anticline, slightly overturned to the east, with a gentle plunge to the north. The LCS deposit is hosted in the gently dipping upper limb of the LCLS. Drill hole Information • The LCS deposit is defined by 73 diamond drill holes, consisting of 37 pre-existing surface and underground holes, drilled between 1964 and 2012; 25 underground holes drilled during prefeasibility studies in 2015 and 2016; and 11 holes drilled in 2017 to support the feasibility study. The current (2015 to 2017) prefeasibility through feasibility study drilling program totals 36 holes and 6,690 m of HQ coring. Campaign (years) # of holes meters drilled location 1964 - 1972 5 6,129 surface 1985 5 1,032 underground 1993 – 1999 7 5,902 surface 2000 - 2009 18 14,807 surface 2012 2 565 underground 2015 - 2017 36 6,690 underground TOTAL 73 35,125 Data aggregation methods • Exploration results have not been reported separately; therefore, this criteria category is not applicable. Relationship between mineralisation widths and intercept lengths • Hole orientations vary between vertical, horizontal, and angled. • Orebody and mineralisation geometry are well defined. • Drill holes pierce the full width of the orebody and mineralised structures. • Hole orientation introduces no material bias to the final Mineral Resource estimate. Diagrams • Diagrams are included in the release as below: • Figure 1 Property location map, Figure 2 LCS drill hole map, Figure 3 LCS geologic interpretation, Figure 4 Section A, and Figure 5 Section B Balanced reporting • Exploration results have not been reported separately; therefore, this criteria category is not applicable. Other substantive exploration data • No additional exploration data to report. Further work • Studies continue to evaluate the potential to mine the extensive skarn mineralisation beyond these currently reported LCS Mineral Resources and Ore Reserves.

Page 13 of 18 Section 3: Estimation and Reporting of Mineral Resources Criteria Commentary Database integrity • All drilling data are securely stored in an acQuire™ geoscientific information management system managed by a dedicated team within RTK. The system is backed up daily. • All collar, survey, assay and geology data loaded to the database are manually verified against original documents. Site visits • The Mineral Resource Competent Person is located on site. Geological interpretation • There is high confidence in the geological interpretation of the primary controls on mineralisation and the ore/waste boundaries of the LCS deposit. • The mineralised host is stratigraphically controlled, and fault-bounded, with clearly distinguishable gangue mineralogy. Cross-cutting intrusive dikes and the deposit bounding monzonite porphyry are easily distinguishable and predictable at the deposit scale. • For the primary mineralized host, the 2015 Rio Tinto Exploration (RTX) 3D wireframe for the LCLS in the Middle Block is considered the baseline and is edited against the new intercepts from the 2015 to 2017 prefeasibility through feasibility study coring programs. • A local northern component of the monzonite intrusive body is wireframed utilizing the historic and contemporary drill hole intercepts and the existing Bingham Mine monzonite wireframe as a guide. • Local latite porphyry intrusions are wireframed using historic and contemporary drilling and mapping in the Common Access Decline, with the existing Bingham Mine latite porphyry wireframe used a guide for overall trend and alignment. • Existing Bingham Mine and RTX Verona fault models are reinterpreted and updated local to the LCS deposit, and the existing fault wireframe for the Smelter fault is carried forward unchanged. • Targeted drilling at multiple orientations provides the primary control of the geologic interpretation. • The geologic interpretation honours the drill hole data and is stratigraphically and structurally coherent. • Wireframes representing geologic domains provide the primary control of Mineral Resource estimation domains. Dimensions • The LCS Mineral Resource is contained within a roughly tabular zone dipping gently north, approximately 40 to 100 m thick, extending 275 m along strike, and 450 m down dip. • The LCS Mineral Resource is located beneath the Bingham Canyon Mine open pit, at approximately the 3700 level (~1,128 m AMSL), immediately adjacent to the active underground drainage gallery workings. Estimation and modelling techniques • The block model designed for grade interpolation has block dimensions of 4.5 m x 4.5 m x 3 m, chosen to reflect the granularity and precision of the geologic model wireframes, mining unit dimensions, and sample support. • Samples are composited on 3 m intervals, breaking on lithological boundaries. Composite length is chosen to match the granularity of the block mode, the maximum assay size and the general observed grade and geological variation downhole. • Detailed statistical analyses, exploratory data analysis (EDA), are completed for all economic and deleterious variables. Box plot analyses are completed for all estimated variables with a breakdown by lithology. Contact plots are completed for Ag, Au, Cu, Mo, to determine boundary conditions and univariate statistics compiled and evaluated for similarities. • Variography is completed for all domains by estimation variable, first by omni-directional variography to establish continuity exists and constrain short range continuity (i.e., the nugget) and then completing directional analyses. • Ordinary Kriging and inverse distance are compared as options for interpolation; Ordinary Kriging was selected as the primary interpolation method for all variables (aside from density) as it is statistically a more robust method that more realistically reflects grade trends, especially in areas of dense data. • Estimation is performed by nested searches of four progressively larger ellipses tied to percentages of each domain’s variogram sill. • A series of 16 sensitivity models are completed and compared in order to establish centrality of the final estimate, controlling for various inputs including number of samples, high yield restrictions, capping, density assignments, variography, and geologic models. • 7 of the 16 sensitivity models are used post-final estimation to determine the variance and sensitivity of the final model. • Resource model validation is completed for all elements against a nearest-neighbour grade estimates representing a declustered population, using swath plots, histograms, quantile-quantile plots, and cumulative distribution comparison, with visual checks in cross-section.

Page 14 of 18 Summary of models completed during sensitivity analysis (BM8 is the final model) Moisture • All Mineral Resource tonnages are estimated and reported on a dry basis. Cut-off parameters • The cut-off grade for the estimate has been based on a Net Smelter Return (NSR) calculation which uses the best understanding of metal prices, recoveries, and mine operating costs. • A $90 NSR cut-off grade was selected based on an evaluation of the optimized Life of Mine production schedule with a series of NSR cut-off values to determine that which generated the highest relative net present value (NPV). • Metal prices used are provided by Rio Tinto Economics and are generated based on industry capacity analysis, global commodity consumption, and economic growth trends. A single long term price point is used in the definition of ore and waste and in the financial evaluations underpinning the Mineral Resource and Ore Reserve statement. The detail of this process and of the price points selected are commercially sensitive and are not disclosed. • Detailed metallurgical testing has been done in conjunction with historic understanding of RTK’s milling, smelting, and refining facilities. • Mine operating costs are informed either from current operations or from a first principal cost build-up using recently tendered market rates. Mining factors or assumptions • The selected mining method is bottom up, sub-level, long hole open stoping, using a primary secondary sequence with cemented backfill. This is a well-known and proven mining method and can be applied effectively within this deposit given the recommended geotechnical limitations. • Geotechnical parameters have been established using detailed, and validated core logging results in combination with geophysical surveys. These have been evaluated against established industry empirical stoping guidelines to generate recommended stable dimensions. Detailed numerical modelling has also been completed to confirm global mine stability and validate the mining sequence. • The most recent resource model has been used for stope generation and optimisation with an effort to maximize NPV and minimize high risk material. In some cases, stopes have dimensions have been reduced, or stopes have been removed where geotechnical recommendations have shown that variable ground conditions could negatively impact the ability to mine these areas. • Stope dimensions are set a 22.9 m high, 15.2 m wide, and a variable length between 15.2 to 9.1 m. Permanent development needed to access the deposit will be 5.9 m high by 5.5 m wide, reducing to 4.9 m high by 5.5 m wide. Stope ground support has been accounted for to aid in stability, this is planned for the backs and sides of the upper drift, as well as the brow from which mucking will occur. • Minimum mining widths have been established and applied to the mine design which underpins the estimate. These are based on the dimensions of the existing mechanized mining fleet, and the expected additional equipment needed to operate the mine (Including allowance for BEV equipment size). Metallurgical factors or assumptions • The metallurgical processes have been developed and optimized based on both the long operating history of the existing onsite concentrator, along with a targeted, in-depth metallurgical testing campaign assessed through laboratory scale test work of samples generated from the resource drilling process. The results of this work informed the performance of the plant when LCS ore is added to the open pit feed, and the ultimate metal recovery of the underground ore component. • All process performance parameters used in the estimate (recoveries, concentrate grades including deleterious elements) are based on the results of both this testing campaign, and historical performance. (Processing recoveries are as follows, 89.9% Cu, 70.5% Au, 75.8% Ag, and 71.3% Mo)

Page 15 of 18 Environmental factors or assumptions • The Mineral Resource estimate assumes a small footprint established in the bottom of the existing open pit, with all other major development to occur underground. • All waste rock and tails will be handled with the open pit waste rock and tails. • All tails from the LCS will be contained within the existing Tailings Storage Facility. • All approvals and permits necessary to mine the Ore Reserves have been obtained. Bulk density • Density samples are taken from 0.1 to 0.2 m of whole core at 9 m intervals. • Specific gravity is determined by using an immersion method using sealed core and using volumetric calculations of dry core samples. • Density is estimated by Simple Kriging in a single pass for the skarn lithology domain, all other lithologies are assigned a single density value by script due to their low variance. Classification • Resource classification criteria are based on the geologic continuity of the stratigraphically and structurally controlled host unit and waste units. Classification by nominal drill hole spacing is as follows: Measured: 23 m Indicated: 46 m Inferred: 91 m • Blocks are coded with nominal drill hole spacing using the average distance of three holes. • Classification volumes are created around contiguous blocks at the stated spacing categories, with consideration for the stated mining method and scale, excluding isolated discontinuous regions. • The classification criteria are deemed fit-for-purpose and are typical of those in use at other skarn-hosted deposits. • Technical review in 2017 deemed the nominal spacing categories adequate for declaring Mineral Resources. Audits or reviews • A comprehensive external review of the LCS resource model was completed in 2017 by Amec Foster Wheeler, concluding that it is suitable for development of a sublevel open stope mine. Additional conclusions were noted in Section 1. Discussion of relative accuracy/ confidence • Mine-wide and individual stope evaluations indicate that the distribution of block grades is not highly skewed, but that there is some marginal material incorporated into stopes. • Evaluations of stope grades and sample spacing indicate that average stope grade is not dependent on distance to nearest sample, with a median sample spacing of 26 m. • Confidence in geological boundaries has not been quantified. The Competent Person has taken into consideration the maturity of the geological model in determining that the continuity of geological features associated with mineralisation is sufficient to support the classification of the Mineral Resource. Section 4: Estimation and Reporting of Ore Reserves Criteria Commentary Mineral Resource estimate for conversion to Ore Reserves • The LCS Ore Reserve estimate was based on the 2017 Mineral Resource model. No material changes have been made (or are available) to the resource model since this date, with the exception of updates to metal prices and mining costs. • Mineral Resources are reported exclusive of Ore Reserves. Site visits • The Ore Reserve Competent Person is located near the mine site and periodically visits the mine and plant sites. Study status • The 2022 Ore Reserve estimate is based on a 2018 feasibility study, as well as a recent review of geotechnical & mining parameters, along with metal prices, and costs. Cut-off parameters • The cut-off grade for the estimate has been based on a Net Smelter Return (NSR) calculation which uses the best understanding of metal prices, recoveries, and mine operating costs. • A $90 NSR cut-off grade was selected based on an evaluation of the optimized Life of Mine production schedule with a series of NSR cut-off values to determine that which generated the highest relative net present value (NPV). • Metal prices used are provided by Rio Tinto Economics and are generated based on industry capacity analysis, global commodity consumption, and economic growth trends. A single long term price point is used in the definition of ore and waste and in the financial evaluations underpinning the Mineral Resource and Ore Reserve statement. The detail of this process and of the price points selected are commercially sensitive and are not disclosed. • Detailed metallurgical testing has been done in conjunction with historic understanding of RTK’s milling, smelting, and refining facilities. • Mine operating costs are informed either from current operations or from a first principal cost build-up using recently tendered market rates.

Page 16 of 18 Mining factors or assumptions • The conversion of the Mineral Resource to an Ore Reserve has been done using a detailed mine design, based on an in-depth evaluation of geotechnical, and operational parameters. • The selected mining method is bottom up, sub-level, long hole open stoping, using a primary secondary sequence with cemented backfill. This is a well-known and proven mining method and can be applied effectively within this deposit given the recommended geotechnical limitations. • Geotechnical parameters have been established using detailed, and validated core logging results in combination with geophysical surveys. These have been evaluated against established industry empirical stoping guidelines to generate recommended stable dimensions. Detailed numerical modelling has also been completed to confirm global mine stability and validate the mining sequence. • The most recent resource model has been used for stope generation and optimisation with an effort to maximize NPV and minimize high risk material. In some cases, stopes have dimensions have been reduced, or stopes have been removed where geotechnical recommendations have shown that variable ground conditions could negatively impact the ability to mine these areas. • Stope dimensions are set a 22.9 m high, 15.2 m wide, and a variable length between 15.2 to 9.1 m. Permanent development needed to access the deposit will be 5.9 m high by 5.5 m wide, reducing to 4.9 m high by 5.5 m wide. Stope ground support has been accounted for to aid in stability, this is planned for the backs and sides of the upper drift, as well as the brow from which mucking will occur. • External dilution (10% for secondaries, 2.5% for primaries) has been applied to the estimate at zero grade based on an evaluation of the geotechnical parameters with established industry empirical dilution guidelines. Given the arrangement of the mine, the majority of waste dilution is estimated to take place within secondary stopes from the adjacent backfilled primaries with a small amount within primaries from the stope infront. • Ore dilution is expected to occur within primary stopes from the adjacent secondaries with an overall net zero change in ore tonnes. This material has not been addressed within the Ore Reserve, but has been accounted for within material movements. • Two distinct recovery factors have been applied to the estimate, the first being a stope shape factor (92.5%) to deduct areas of the stope which cannot be practically drilled such as the stope “shoulders”. The second being a mining recovery factor (90%) to account for drilled and blasted material or dilution which cannot be mucked out from the stope. Both of these factors have been established based on the experience of the personnel on site with these mining methods and have been validated via internal and external reviews. • Minimum mining widths have been established and applied to the mine design which underpins the estimate. These are based on the dimensions of the existing mechanized mining fleet, and the expected additional equipment needed to operate the mine (Including allowance for BEV equipment size). • The mine production schedule for the feasibility study was derived using Inferred Mineral Resources (<1% of Total). The deduction of these resource volumes has proven to make no material impact to the outcome of the overall economic evaluation. • The mining method relies on the establishment of a Cemented Aggregate Fill (CAF) plant. This plant is currently planned for construction during 2022/23. Metallurgical factors or assumptions • The metallurgical processes have been developed and optimized based on both the long operating history of the existing onsite concentrator, along with a targeted, in-depth metallurgical testing campaign assessed through laboratory scale test work of samples generated from the resource drilling process. The results of this work informed the performance of the plant when LCS ore is added to the open pit feed, and the ultimate metal recovery of the underground ore component. • All process performance parameters used in the estimate (recoveries, concentrate grades including deleterious elements) are based on the results of both this testing campaign, and historical performance. (Processing recoveries are as follows, 89.9% Cu, 70.5% Au, 75.8% Ag, and 71.3% Mo) Environmental • The estimate assumes a small footprint established in the bottom of the existing open pit, with all other major development to occur underground. • All by-products from the material processed can be contained within the existing Tailings Storage Facility with no changes needed to accommodate the LCS. • All approvals and permits necessary to mine the Ore Reserves have been obtained. Infrastructure • Much of the required infrastructure for the estimate is already available via existing site facilities. This includes mechanical and electrical infrastructure operating within an established drainage gallery tunnel which is currently used to dewater the existing open pit. • Decline development will be extended from the existing drainage gallery tunnel to access the LCS and establish ventilation connections. • An additional CAF Plant will be constructed adjacent to the portal, and an upgraded underground ventilation facility will be established to achieve required airflows. • All personnel and materials will access the operation via the open pit and operations will be

Page 17 of 18 integrated with the existing drainage gallery maintenance. • Ore material will be rehandled at the drainage gallery portal using open pit equipment and hauled to the open pit crusher to be comingled with open pit material. • All downstream processing will be done with the existing on-site infrastructure. Costs • Development capital costs are based on recent feasibility level estimates. • Operating costs are based on a first principle estimate derived for each additional underground activity. Both estimates utilize historical cost data where available. • Estimates of prices for consumables are based on historical pricing and global commodity consumption and economic growth trends. • Transportation and treatment charges for existing facilities are based on historical and projected estimates. • There are no royalty obligations. The estimate includes an allowance for Utah state severance tax. • Due to the commercial sensitivity of these assumptions, an explanation of the methodology used to determine these assumptions has been provided, rather than the actual figures. Revenue factors • Revenue projections are based on combined open pit and underground projected mill head grades, process recovery losses and product prices. • The revenue analysis includes other factors within the calculation such as the processing development ore, or low-grade ore from underground which is above the open pit cut-off. • The LCS project uses metal prices provided by Rio Tinto Economics and are generated based on industry capacity analysis, global commodity consumption, and economic growth trends. A single long term price point is used in the definition of ore and waste and in the financial evaluations underpinning the Mineral Resource and Ore Reserve. The detail of this process and of the price points selected are commercially sensitive and are not disclosed. Market assessment • All Ore Reserve products, other than molybdenum, are sold on open markets with no long-term contract commitments. Molybdenum is sold through contracts with roaster facilities. Economic • The economic analysis for the LCS is based on the incremental cash flow that is generated through the existing ore processing facilities as a result of the additional mineralized material from the LCS which is added to the open pit mine feed. • This economic calculation includes other factors such as the cost of material rehandling, the cost of pit ore deferral, and the impact of deleterious elements. • Economic inputs such as carbon pricing, inflation and discount rates are also generated internally at Rio Tinto. The detail of this process is commercially sensitive and not disclosed. • Economic evaluation using Rio Tinto long-term prices demonstrates a positive net present value for the LCS Ore Reserves. • When viewed in isolation, the resulting economics for LCS are sensitive to metal pricing due to the size and duration of the project. The LCS does however provide a benefit as the first phase of modern underground mining at Bingham Canyon from which larger projects can leverage. Social • The mining tenure is wholly owned, and all permits necessary to mine the Ore Reserve have been obtained. Other • Ongoing project risk assessments have been conducted throughout the duration of the feasibility study, and project development. • The estimate leverages the existing established licence to operate for the open pit mine operating area. Classification • The basis for the Ore Reserve classification is the established Mineral Resource confidence categories for the deposit along with the consideration of all modifying factors. • Measured and Indicated Mineral Resources within the Ore Reserve boundaries are classified as Probable Ore Reserves. • Proved Ore Reserves have not been included due to the lack of recently demonstrated stope performance with respect to stope dimensions, productivity and costs. • Any Inferred Mineral Resources within the Ore Reserve boundaries (<1% of Total) have been included within the Probable Ore Reserve volume at zero grade; constituting internal dilution. The deduction of these resource volumes has proven to make no material impact to the outcome of the overall economic evaluation. Audits or reviews • A comprehensive formal external review of the LCS was completed in 2017 by Amec Foster Wheeler, concluding that it is suitable for development of a sublevel open stope mine. Discussion of relative accuracy/ confidence • The accuracy of the Ore Reserve estimate is based on the results of the Feasibility study and an assessment of economic factors. • The build-up of the geotechnical assumptions which underpin the stope sizes, mining methods and dilution is based on sound data which has been validated and peer reviewed, but no operational data is available to corroborate these assumptions. • Similarly, production rates and costs for the LCS to operate within the open pit are also developed using sound basis but are yet to be demonstrated.

Page 18 of 18 • It is expected that as stoping operations continue, modifying factors such as stope dimensions, dilution, mining recovery, productivity and cost assumptions will be better understood and refined based on actual observed / measured data.

Media release

Response to Energy Resources of Australia’s independent valuation report

29 September 2022

MELBOURNE--(BUSINESS WIRE)-- Rio Tinto notes the independent valuation report released by Energy Resources of Australia (ERA) on 26 September 2022, to determine a valuation of the company as it seeks to address material cost and schedule overruns on the critical Ranger rehabilitation project in Australia’s Northern Territory.

Rio Tinto understands the long-term opposition the Traditional Owners, the Mirarr People, have to further mining development on their country and acknowledges the statement of the Gundjeihmi Aboriginal Corporation on 28 September 2022 setting out their views of the independent valuation report and its failure to give due weight to their consistent and inter-generational opposition to further uranium mining on their country.

Rio Tinto remains committed to ensuring the rehabilitation is completed to a standard that will establish an environment similar to the adjacent Kakadu National Park and continues to provide technical support to the project. The company has always believed that the rehabilitation of Ranger can be successfully achieved in a way that is consistent with the wishes of the Mirarr People and have sought to work constructively with ERA’s Independent Board Committee (IBC) in its efforts to find a funding solution to meet ERA’s rehabilitation obligations.

Rio Tinto’s consistent position is that the terms of any ERA funding solution should reflect fair value having regard to:

•the material cost overruns and interim funding requirements;

•funds raised will be dedicated strictly to rehabilitation and not any future development; and

•the Traditional Owners, the Mirarr People’s consistently publicly stated opposition to developing the Jabiluka uranium deposit.

In July 2022, when the ERA IBC failed to obtain major shareholder support for its proposed offer terms, Rio Tinto offered to subscribe for its full pro-rata entitlement at an offer price that reflects Rio Tinto’s view of fair value. This offer to ERA remains.

In Rio Tinto’s view, the independent valuation report prepared by Grant Thornton and adopted by the IBC to help set the price for a future entitlement offer, fails to appropriately recognise the long-standing opposition of the Mirarr People to further uranium mining on their country. Rio Tinto understands that this causes distress for the Mirarr elders and community.

Rio Tinto chief executive Australia Kellie Parker said “We are actively seeking to reflect the wishes of the Mirarr People in our approach to the funding of ERA’s rehabilitation commitment having long understood their opposition to further mining on their country.

“We believe the successful rehabilitation of the Ranger Project Area, which is of critical importance to the Mirarr People, Rio Tinto and ERA can be achieved in a way that is consistent with the Mirarr People’s wishes. This remains our utmost priority and commitment.

“We are again asking the ERA IBC to urgently develop a workable plan to fund the increased rehabilitation costs.”

This announcement is authorised for release to the market by Steve Allen, Rio Tinto’s Group Company Secretary.

Rio Tinto starts demonstration plant for lithium concentration in Quebec

29 September 2022

SOREL-TRACY, Quebec--(BUSINESS WIRE)-- Rio Tinto has started producing spodumene concentrate, a mineral used in the production of lithium for batteries, at a demonstration plant in its Rio Tinto Iron and Titanium (RTIT) Quebec Operations in our metallurgical complex in Sorel-Tracy, Canada.

The plant will demonstrate at industrial scale a new spodumene concentration process that provides lithium oxide (Li20) grades and recoveries well above the industry average. The process was developed by researchers at Rio Tinto’s Critical Minerals and Technology Centre and tested on spodumene ore samples from various countries. It offers the environmental benefit of not using chemical products and generating only dry, inert residues.

RTIT Managing Director Stéphane Leblanc said: “Rio Tinto is exploring new, sustainable ways to extract battery materials for the energy transition. We are seeing strong interest in the market for a North American supply of spodumene concentrate to support production of lithium batteries. Our demonstration plant will allow us to further validate the innovative spodumene concentration process developed at our Critical Minerals and Technology Centre as we consider moving to commercial scale production.”

The demonstration plant was commissioned in June after successful laboratory testing of the new process and produced its first ton of spodumene concentrate in July 2022. It will test ore from various local suppliers including Sayona, an emerging lithium producer with projects in Québec and Western Australia.

Notes to editors

Rio Tinto is committed to the battery materials sector and lithium’s role in a low carbon future. The company’s portfolio of lithium projects focuses on leading edge mining and processing technology to deliver environmentally sensitive solutions to the production of battery-grade lithium carbonate for electric vehicles.

In March 2022, Rio Tinto completed the acquisition of the Rincon lithium project, a large undeveloped lithium brine project located in the heart of the lithium triangle in Argentina. This long life, scaleable project has the potential to have one of the lowest carbon footprints in the industry. Rio Tinto also recovers battery-grade lithium from waste material using a breakthrough process at its Boron operations in California and owns the Jadar lithium-borate project in Serbia.

In June 2022, Rio Tinto announced a $10 million strategic equity investment in Nano One, a Vancouver-based technology company with a patented industrial process to produce low-cost, high-performance cathode used in lithium-ion batteries. This partnership contemplates the potential use of Rio Tinto’s battery metal products, including iron powders from RTFT and lithium, as feedstock for the production of Nano One’s cathode materials.
