Rio Tinto releases fourth quarter production results 16 January 2025 Rio Tinto Chief Executive Jakob Stausholm said: “Our operating performance in 2024 was good, consistent with our ongoing commitment to strengthen the business as we execute our strategy to deliver profitable growth. The implementation of our Safe Production System has again contributed to greater consistency across key operations, including our iron ore assets in the Pilbara and our bauxite operations in Australia, where Amrun and Gove achieved record annual production. “We are making strong progress in delivering organic growth from our major projects. The Oyu Tolgoi underground copper mine in Mongolia continues to successfully ramp up, while the Simandou high-grade iron ore project in Guinea and our Western Range mine in the Pilbara are on schedule for first production this year. “Significant milestones were achieved at our Rincon project in Argentina during the quarter, with first lithium delivered and receipt of Board approval to expand the operation, demonstrating both our operational capabilities and ambition to grow in battery materials. "We remain focused on executing our strategy to deliver attractive shareholder returns and build a stronger, more diversified, and growing business, driven by our confidence in the long-term demand for materials essential to the global energy transition.” Production1 Q4 2024 vs Q4 2023 vs Q3 2024 2024 vs 2023 Pilbara iron ore shipments (100% basis) Mt 85.7 -1 % +1 % 328.6 -1 % Pilbara iron ore production (100% basis) Mt 86.5 -1 % +3 % 328.0 -1 % Bauxite Mt 15.4 +2 % +2 % 58.7 +7 % Aluminium2 kt 837 -1 % +3 % 3,296 +1 % Mined copper (consolidated basis) kt 202 +26 % +21 % 697 +13 % Titanium dioxide slag kt 235 -14 % -11 % 990 -11 % IOC3 iron ore pellets and concentrate Mt 2.5 -6 % +20 % 9.4 -2 % 1 Rio Tinto share unless otherwise stated. 2 Includes primary aluminium only. 3 Iron Ore Company of Canada. Q4 2024 operational highlights and other key announcements • In October, Morlaye Camara, an employee of one of our contractors at the SimFer Port Project in Morebaya, part of the Simandou project, was injured, and subsequently passed away. During the quarter, we completed our internal investigation and the findings were shared across the business. • Our all injury frequency rate (AIFR) for the fourth quarter was 0.38, a decrease from the third quarter of this year (0.41) and the fourth quarter of 2023 (0.39). The health, safety and wellbeing of our people and partners remains our priority. • In 2024, we delivered 1% production growth and a 3% increase in sales volumes, both on a copper equivalent basis (based on long-term consensus pricing). At our Investor Seminar in December, our Executive Committee outlined our ambition for a decade of around 3% compound annual growth in copper equivalent production, driven by Oyu Tolgoi, Simandou and our new lithium portfolio. • Pilbara operations produced 328.0 million tonnes in 2024, with shipments of 328.6 million tonnes, each 1% lower than 2023. Productivity improvements of 10 million tonnes did not fully offset depletion, predominantly at Yandicoogina and Paraburdoo, as we transition to Western Range. The Safe Production System target of 5 million tonnes for 2024 was achieved and Gudai-Darri reached 50 million tonne per annum rates during 2024. • Bauxite production was 58.7 million tonnes in 2024, 7% higher than 2023, exceeding our guidance. The improvement was driven by the implementation of the Safe Production System, delivering record annual production at Amrun and Gove, with the former currently operating above nameplate capacity. Notice to ASX/LSE Rio Tinto | Fourth quarter operations report 1 EXHIBIT 99.1

• Aluminium production of 3.3 million tonnes was 1% higher than 2023, following the ramp-up of Kitimat and completion of cell recovery efforts at Boyne in the prior year, together with increased ownership of Boyne and New Zealand Aluminium Smelter (NZAS). These were partially offset by the continued closure program at Arvida and a request to reduce energy usage at NZAS, resulting in lower output. Production at NZAS is expected to be fully ramped up in the second quarter of 2025. • Mined copper production of 697 thousand tonnes (consolidated basis) in 2024 was 13% higher than 2023, reflecting the ramp up of Oyu Tolgoi underground and increased production from Escondida due to higher grades fed to the concentrator (0.99% versus 0.83%). This offset geotechnical challenges at Kennecott as instabilities in the pit wall impacted the mining sequence from the second quarter. • On 4 December, we signed a Term Sheet with Sumitomo Metal Mining (SMM) for a Joint Venture to deliver the Winu copper-gold project in Western Australia. We will continue to develop and operate Winu as managing partner and SMM will pay $195 million upfront, and $204 million in deferred consideration, contingent on milestones and adjustments to be agreed. We will now work to finalise definitive agreements in the first half of 2025, along with formalising the broader strategic partnership. • Titanium dioxide slag production of 990 thousand tonnes in 2024 was 11% lower than 2023 due to reduced market demand. A furnace reconstruction, starting in the first quarter of 2024, continues at our RTIT Quebec Operations. Through 2024, we operated six out of nine furnaces in Quebec and three out of four at Richards Bay Minerals (RBM). • IOC production of 9.4 million tonnes in 2024 was 2% lower than 2023 due to an 11-day site-wide shutdown driven by forest fires in mid-July, resulting in a revised mine plan and maintenance schedule. We also experienced operational challenges in the mine and concentrator throughout the year. • At the end of 2024, we had commenced deployment of the Safe Production System at 31 (~80%) of our sites, including three additional sites in the fourth quarter. We achieved our Safe Production System target of 5 million tonnes production uplift for Pilbara Iron Ore and two of our sites delivered their best production performance on record in the quarter. • On 9 October, we announced a definitive agreement to acquire Arcadium Lithium plc (Arcadium) in an all-cash transaction for US$5.85 per share. This transaction will bring Arcadium’s world-class, complementary lithium business into our portfolio, establishing a global leader in energy transition commodities. During the quarter, we made good progress on the outstanding conditions, with Arcadium announcing that it had obtained all requisite shareholder approvals for the proposed acquisition. We have received most of the required foreign investment approvals, including clearance by the Committee on Foreign Investment in the United States (CFIUS) in January 2025, and all of the required merger control clearances. Closing of the transaction remains subject to foreign investment approvals in Australia and Canada, approval of the Royal Court of Jersey and other closing conditions, and is expected to occur before mid-2025. • On 2 December, we completed the sale of Dampier Salt Limited’s Lake MacLeod operation to Leichhardt Industrials Group. The consideration of A$375 million was received in December. • On 6 December, we completed the sale of Sweetwater, a former uranium legacy site in Wyoming, United States. The consideration of $175 million was received in December. • On 12 December, we announced the approval of $2.5 billion1 to expand the Rincon project in Argentina, our first commercial scale lithium operation, to an annual capacity of 60,000 tonnes of battery grade lithium carbonate. Mine life is expected to be 40 years2, with construction of the expanded plant scheduled to begin in mid-2025, subject to permitting. First production is expected in 2028 with a three-year ramp-up to full capacity. The project uses direct lithium extraction (DLE) technology, a process that supports water conservation, reduces waste and produces lithium carbonate more consistently than other methods. • On 19 December, we announced the appointment of Georgie Bezette as our new Chief People Officer, succeeding James Martin, who retired at the end of 2024. All figures in this report are unaudited. All currency figures in this report are US dollars, and comments refer to Rio Tinto’s share of production, unless otherwise stated. 1 Included in the Group’s capital expenditure guidance provided at our Investor Seminar on 4 December 2024. 2 The production target of approximately 53 kt of battery grade lithium carbonate per year for a period of 40 years was previously reported in a release to the ASX dated 4 December 2024 titled “Rincon Project Mineral Resources and Ore Reserves: Table 1”. Rio Tinto confirms that all material assumptions underpinning that production target continue to apply and have not materially changed. Plans are in place to build for a capacity of 60 kt of battery grade lithium carbonate per year with debottlenecking and improvement programs scheduled to unlock this additional throughput.

For further details see slide 90 of our Investor Seminar 2024 presentation. 4 Around the bottom end. • 2025 production guidance is unchanged since December 2024. • Pilbara iron ore guidance remains subject to the timing of approvals for planned mining areas and heritage clearances. SP10 levels are expected to remain elevated until replacement projects are delivered. • Iron ore shipments and bauxite production guidance remain subject to weather impacts. Operating costs • Guidance for 2025 Pilbara iron ore and copper C1 unit cash costs will be provided in the 2024 full year results release due on 19 February 2025. • 2024 Pilbara iron ore unit cash costs are expected to be in the upper half of our $21.75 to $23.50 per tonne guidance (based on an average A$:US$ exchange rate of 0.66). This is due to inflation being at the higher end of our expectations and lower production. • 2024 copper C1 unit costs are expected to be unchanged at 140 to 160 US cents/lb guidance. Aluminium modelling To assist with modelling of aluminium operating costs during a volatile price environment for raw materials, we provide the following breakdown and sensitivities for the alumina and aluminium metal segments (Primary Metal and Pacific Aluminium).

Investments, growth and development projects • Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in 2024 was $935 million, compared with $855 million in 2023 (excluding Simandou). Approximately 25% of the spend was by central exploration, 23% by Minerals (with the majority focusing on lithium), 36% by Copper, 14% by Iron Ore and 2% by Aluminium. In 2024, all qualifying expenditure relating to Simandou is being capitalised. Qualifying expenditure on the Rincon project has been capitalised since 1 July 2024. Pilbara projects • Construction of our Western Range mine is now over 90% complete with fabrication and overland conveyor belt installation finalised.  We continue to focus on completion of the new crushing and screening facilities, with first ore from that new system on plan for the first half of 2025. • We continue to advance our next tranche of Pilbara mine replacement projects at Hope Downs 1 (Hope Downs 2 and Bedded Hilltop), Brockman 4 (Brockman Syncline 1), Greater Nammuldi and West Angelas. Funding for the full execution of the Brockman 4 project was obtained during the quarter. Early works and design are underway for the Brockman 4 and the Hope Downs 1 projects. Environmental and heritage approvals are progressing and timelines remain subject to receiving these approvals. The Greater Nammuldi project continues to progress at a rate behind the original development schedule. • The Rhodes Ridge pre-feasibility study, which is targeting an initial capacity of up to 40 million tonnes per year, subject to relevant approvals, remains on track to be completed in 2025. First ore is expected by the end of the decade. • Early works activities at our Coastal Water desalination project progressed with earthworks materially complete and several key contract packages awarded during the quarter. The $395 million plant will provide water to our port operations in Dampier. At full capacity, it will produce approximately 4GL/year to reduce draw from the Bungaroo aquifer to sustainable levels. We are assessing a further phase of the project. • We are progressing engineering works for the replacement of all three bucketwheel reclaimers and associated infrastructure within the Parker Point Stockyard at our Dampier Port. Early enabling works are progressing well, with several contract packages awarded in the quarter and fabrication of the reclaimers commencing in December. Oyu Tolgoi underground project • First ore on the conveyor to surface belt was achieved in October 2024, with the conveyor system now able to transport ore to the surface from a depth of 1,300 metres. Load and production testing of the conveyor system is progressing. • Construction works for the concentrator conversion remain on schedule.  Commissioning activities commenced during the quarter and are forecast to be progressively completed through to the second quarter of 2025. • Construction of primary crusher 2 is progressing to plan and remains on track to be completed by the end of 2025. Simandou iron ore project • The SimFer mine1 is on track to deliver first production at the mine gate in 2025, ramping up over 30 months to an annualised capacity of 60 million tonnes per year2 (27 million tonnes per year Rio Tinto share). • For the SimFer mine, bulk earthworks are progressing to plan, despite productivity being impacted by wet weather during the quarter. All mine construction contracts are complete, and the two initial crushers are now commissioned, with first ore crushed on 1 January 2025. Rio Tinto | Fourth quarter operations report 5

• During the fourth quarter, all construction milestones for the period stipulated by the Government of Guinea were achieved for the SimFer infrastructure scope. In connection with SimFer’s scope of the 620 kilometre long multi-use TransGuinean railway line, which will connect Simandou’s mine operations to the port facilities, with the arrival of track laying locomotives, 8.5 kilometres of rail was installed and in October construction of the 275 metre Milo River bridge was completed. Tunnel excavation activity on the SimFer scope is now more than 75% complete, with construction at the port continuing to advance on the transhipment vessel (TSV) wharf and rail car dumper infrastructure. Expectations for delivery of the first trans shipping vessels remain on plan. • The current total workforce across all the Simfer scope of mine, rail and port is 13,300 with 81% national Guinean participation. Other key projects and exploration and evaluation • The AP60 expansion project in Quebec remains on schedule. Construction activities during the quarter included commencement of installation of the silo for the gas treatment centre, busbar and the first floor slabs. Once completed, the project will add 96 new AP60 pots, increasing AP60 capacity by 160,000 tonnes of primary aluminium per year by the end of 2026. This new capacity, in addition to 30,000 tonnes of new recycling capacity at Arvida expected to open in the fourth quarter of 2025, will offset the 170,000 tonnes of capacity lost through the gradual closure of potrooms at the Arvida smelter from 2024. • At Kennecott, activities continued on the North Rim Skarn (NRS) underground development and infrastructure. Production from NRS is forecast to commence in mid-2025, delivering around 250,000 tonnes through to 20333. • At the Resolution Copper project in Arizona, we continue to await a decision from the U.S. Supreme Court on the petition filed by the Apache Stronghold requesting to hear its case to stop the land exchange between Resolution Copper and the federal government. Separately the Supreme Court denied a petition from the San Carlos Apache Tribe, asking the Court to review a decision by the Arizona Supreme Court regarding a water discharge permit issued to Resolution Copper. We continue to progress the Final Environmental Impact Statement with the United States Forest Service, however they have yet to advise on the date of republication. We also advanced partnership discussions with several federally-recognised Native American Tribes. While there is significant local support for the project, we respect the views of groups who oppose it and will continue our efforts to address and mitigate concerns. • At the Winu copper-gold project in Australia, we signed a Term Sheet with Sumitomo Metal Mining (SMM) in December for a Joint Venture to deliver the project. A pre-feasibility study with an initial development of processing capacity of up to 10 million tonnes per year is expected to be completed in 2025, along with the submission of an Environmental Review Document under the EPA Environmental Impact Assessment process. Project Agreement negotiations with Nyangumarta and the Martu Traditional Owner Groups remain our priority. • Nuton, our copper heap leaching technology venture, continues to develop its path towards deployment with ten partnerships in five countries: United States, Mexico, Chile, Peru and Argentina. Construction is progressing at our first large scale deployment site at Gunnison’s Johnson Camp Mine in Arizona, where we expect to achieve first copper in the second half of 2025. Work on the second industrial scale deployment for potential implementation in 2025 is well underway. Additionally, in the fourth quarter, Nuton signed an Option to the Joint Venture Agreement with Aldebaran Resources for the Altar project and also increased its ownership to 17.2% in McEwen's Los Azules project. Both projects are located in San Juan Province, Argentina. • At the Rincon project in Argentina, first lithium was produced from the 3,000 tonne starter plant in November. Full commissioning and plant ramp-up continues, with project completion expected in the first quarter of 2025. The feasibility study for the full-scale operation was completed during the quarter, with our Board approving an investment of $2.5 billion to expand Rincon’s capacity to 60,000 tonnes4 of battery grade lithium carbonate per year. We released the Rincon Project Mineral Resources and Ore Reserves statement on 4 December.   Rio Tinto | Fourth quarter operations report 6

• At the Jadar project in Serbia, the application process for obtaining the Exploitation Field Licence (EFL) continued during the fourth quarter. The EFL is essential for commencing fieldwork, including detailed geotechnical investigations, while cultural heritage and environmental surveys have resumed. The Environmental Impact Assessment process for the scoping and content for the mine progressed through the public consultation phase. This step includes legally mandated consultations, which the project supports, to encourage an open, fact-based dialogue. 1 Simfer Jersey Limited is a joint venture between the Rio Tinto Group (53%) and Chalco Iron Ore Holdings Ltd (CIOH) (47%), a Chinalco- led joint venture of leading Chinese SOEs (Chinalco (75%), Baowu (20%), China Rail Construction Corporation (2.5%) and China Harbour Engineering Company (2.5%)). Simfer S.A. is the holder of the mining concession covering Simandou Blocks 3 & 4, and is owned by the Guinean State (15%) and Simfer Jersey Limited (85%). Simfer Infraco Guinée S.A.U. will deliver Simfer’s scope of the co-developed rail and port infrastructure, and is co-owned by Simfer Jersey (85%) and the Guinean State (15%). Simfer Jersey will ultimately own 42.5% of Compagnie du Transguinéen, which will own and operate the co-developed infrastructure during operations. 2 The estimated annualised capacity of approximately 60 million dry tonnes per annum iron ore for the Simandou life of mine schedule was previously reported in a release to the ASX dated 6 December 2023 titled “Investor Seminar 2023”. Rio Tinto confirms that all material assumptions underpinning that production target and those production profiles continue to apply and have not materially changed. 3 The NRS production target of around 250 thousand tonnes of additional mined copper over ten years (2023 to 2033) at Kennecott was previously reported in a release to the Australian Securities Exchange (ASX) dated 20 June 2023 titled “Rio Tinto invests to strengthen copper supply in US”. Rio Tinto confirms that all material assumptions underpinning the production targets continue to apply and have not materially changed. 4 The production target of approximately 53 kt of battery grade lithium carbonate per year for a period of 40 years was previously reported in a release to the ASX dated 4 December 2024 titled “Rincon Project Mineral Resources and Ore Reserves: Table 1”. Rio Tinto confirms that all material assumptions underpinning that production target continue to apply and have not materially changed. Plans are in place to build for a capacity of 60 kt of battery grade lithium carbonate per year with debottlenecking and improvement programs scheduled to unlock this additional throughput.

Sustainability highlights Workplace culture During the fourth quarter, we completed one of the final recommendations of the Everyday Respect report; publishing an independent progress review conducted by Elizabeth Broderick & Co. Change is happening: one of the findings indicates people are more empowered to speak up and Everyday Respect is now widely considered a normal conversation within the company, which is a critical step for culture change. Achieving the sustained progress we want to see will require ongoing focus and effort. Guided by the Progress Review, we have shaped the next stage of our plan which will continue to drive progress towards becoming an organisation where everyone, everywhere feels safe, respected and empowered. Communities & Social Performance (CSP) In November, as a result of Rio Tinto taking up its pro rata entitlements in the offer from Energy Resources of Australia (ERA), and the level of participation by other ERA shareholders, Rio Tinto holds over 98% of ERA’s shares. Rio Tinto intends to proceed with the compulsory acquisition of all remaining ERA shares that it does not currently own. This underlines our commitment to the rehabilitation of the Ranger mine. In December, we welcomed the release of the Panguna Mine Legacy Impact Assessment (PMLIA) report as a critical step forward in building understanding of the long-term legacy impacts of the former mine in Bougainville. The independent report assesses the environmental impacts and directly connected social and human rights impacts caused by the Panguna mine since Bougainville Copper Limited (BCL) ceased operations in 1989. Earlier in the quarter, we signed a Memorandum of Understanding with the Autonomous Bougainville Government (ABG) and BCL to form a roundtable to address the PMLIA findings and develop a remedy mechanism consistent with UN Guiding Principles on Business and Human Rights.

Our markets The global economy is showing resilience with inflation moderating and growth stabilising, although risks of geopolitical tensions and persistent labour shortages remain. China’s economic growth drivers continue to shift from the property sector to advanced manufacturing and new technologies. • The Chinese economy provided mixed signals during the quarter. It still faces headwinds from an ongoing property market oversupply, although the November data on home sales and prices showed signs of stabilisation following many months of policy loosening. Manufacturing and consumer durables further improved given increased subsidies to support consumption. • The US economy has outperformed other developed economies and its outlook remains stable. In particular, the tech sector showed further strength in the fourth quarter, capping off a year of strong growth. However, the housing and building construction market showed mixed signals during the quarter, as residential starts and completions trended downwards in the latter part of 2024, while existing and new home sales saw an uptick in November. • The eurozone outlook continues to be uncertain, with uneven growth across the region and consumption remaining subdued. Persistent manufacturing weakness and cross-country divergence make a strong recovery unlikely. However, the resilience of the labour market is expected to favour wage growth and slow disinflation. • Iron ore prices decreased by 8% over the quarter, while the average monthly price in the fourth quarter of $103/dmt (Platts CFR 62% Fe index) was 4% higher than the third quarter. China’s crude steel production recovered to an annualised run-rate of more than one billion tonnes, as elevated steel exports partly offset domestic demand weakness. Seaborne supply declined by ~2% quarter on quarter in line with typical seasonality. China's iron ore inventories at 47 major ports drew down slightly during the quarter to 156Mt, although this level is still 31Mt higher than at the start of 2024. • The LME aluminium price decreased by 4% over the quarter, while the average price increased by 8% from the third quarter to $2,575/t. There was price support from high alumina costs and the cancellation of Chinese VAT rebates on semi-finished goods (semis) exports. Aluminium market spot premiums ended the fourth quarter at multi-year highs in the Japan and US, with the latter also supported by potential US tariffs on aluminium imports. China’s aluminium production remained close to its capacity cap of 45 million tonnes, although fell back slightly after curtailments driven by high input costs. Ex-China aluminium semi-fabricated shipments slowed, driven by weak demand for extrusions and rolled products in the transport, building and construction sectors. Overall, the global market was in a slight deficit with inventories falling to lower levels compared to the historical norm. The Australian FOB alumina price corrected towards the end of the quarter to $672/t, down from its peak level in early December. China’s bauxite import prices surged in the fourth quarter, mainly driven by firm demand and disruptions to Guinean bauxite exports since early October. • The LME copper price decreased by 11% over the quarter, while the average price was flat quarter on quarter at $4.17/lb. Following the US elections, copper prices were weighed down by tariff risks and a strong dollar, dampening investor interest. China’s refined copper consumption remained robust, but demand in the rest of the world was mixed, with manufacturing PMIs underperforming. After a counter-seasonal inventory build in the first half of the year, copper inventory drawdowns resumed in the fourth quarter, in line with historical trends. However, the refined copper market was still in surplus in 2024. In contrast, the copper concentrate market remains tight due to excess smelter capacity, with the 2025 benchmark treatment charges (TCs) settling at $21/dmt, the lowest in two decades. • Lithium demand continues to expand at double-digit growth on the back of strong global EV sales, up 25% year-on-year in the first eleven months of 2024, compared to 34% year-on-year for the same period of 2023. Supply cuts are gaining traction due to persistent price weakness, with Australia accounting for most of the output cuts and project delays. This pullback in production could tighten the market in 2025 and beyond. • The TiO2 market has shown mixed trends throughout 2024. Increased TiO2 pigment production has supported feedstock consumption, but feedstock purchases have been impacted by surplus inventory. Western pigment producers have increased operating rates in response to improved demand, while Chinese pigment producers are facing increasing pressure from tariffs and a weak domestic market. Interest rate cuts and improving home sales in the US are positive for feedstock demand. Rio Tinto | Fourth quarter operations report 9

• Demand for borates continues to be stable, although uneven amongst end-use sectors. Agriculture demand growth has been positive. Industrial-related demand (i.e fibre glass) in China is projected to grow marginally for the full year, supported by an increase in exports, while housing sector demand in China and Europe remains depressed.

The consolidated basis sales reported here include Robe River Iron Associates on a 65% basis to enable comparison with revenue reported in the financial statements. Pilbara operations We produced 86.5 million tonnes (Rio Tinto share 73.6 million tonnes) in the fourth quarter, 1% lower than the corresponding period of 2023. Mine productivity mostly offset depletion and higher than average rainfall, which was more than five times historical levels. As a result, mine stocks were drawn down, with operations in the first quarter of 2025 to focus on recovering pit health. Shipments of 85.7 million tonnes (Rio Tinto share 72.3 million tonnes) were 1% lower than the fourth quarter of 2023. SP10 volumes accounted for 25%1 of shipments in the fourth quarter, higher than the first three quarters of 2024 (18%). SP10 levels are expected to remain elevated until replacement projects are delivered. We are reviewing our future product strategy, having regard to customer requirements and available ore grades. Full year mine production of 328.0 million tonnes was 1% lower than 2023, with shipments also 1% lower. Production was affected by depletion, predominantly at Paraburdoo as we transition to Western Range and Yandicoogina, as well as higher than average rainfall. The Safe Production System target of 5 million tonnes for 2024 was achieved. Gudai-Darri demonstrated 50 million tonne per annum rates during the fourth quarter. Sustaining production at these rates is subject to the timing of approvals for planned mining areas and heritage clearances, and continuation of the debottlenecking program at the main plant. Approximately 10% of sales in 2024 were priced by reference to the prior quarter’s average index lagged by one month. The remainder was sold either on current quarter average, current month average, average of two months, forward month or on the spot market. Approximately 25% of sales in 2024 were made on a free on board (FOB) basis, with the remainder sold including freight. Rio Tinto | Fourth quarter operations report 11

Achieved average pricing in 2024 was $89.6 per wet metric tonne ($99.7 in 2023) on an FOB basis (equivalent to $97.4 per dry metric tonne, with an 8% moisture assumption). This compares to the average price for the monthly average Platts index for 62% iron fines converted to a FOB basis of $98.4 per dry metric tonne. China Portside Trading Our iron ore portside sales in China were 9.5 million tonnes in the fourth quarter of 2024 (5.8 million tonnes in the fourth quarter of 2023), leading to a total of 29.9 million tonnes in 2024 (23.3 million tonnes in 2023). At the end of the December, inventory levels were 7.1 million tonnes, including 4.9 million tonnes of Pilbara product. In 2024 approximately 89% of our portside sales were either screened or blended in Chinese ports (86% in 2023). 1 Based on total Pilbara shipments on a 100% basis.

Aluminium Rio Tinto share of production (‘000 tonnes) Q4 2024 vs Q4 2023 vs Q3 2024 2024 vs 2023 Bauxite 15,412 +2 % +2 % 58,653 +7 % Bauxite third party shipments 10,627 -1 % -4 % 40,935 +10 % Alumina 1,992 +4 % +13 % 7,303 -3 % Aluminium 837 -1 % +3 % 3,296 +1 % Recycled aluminium 58 n/a -7 % 264 n/a Bauxite Bauxite production of 15.4 million tonnes was 2% higher than the fourth quarter of 2023. Implementation of the Safe Production System continued to drive higher plant availability and utilisation rates, especially at our Amrun mine at Weipa. We remain focused on continued operational improvement as we enter a quarter typically impacted by wet weather. Full year 2024 production was 58.7 million tonnes, 7% higher than 2023, exceeding our guidance. We delivered record annual production at Gove and Amrun, with the latter currently operating above nameplate capacity. We shipped 10.6 million tonnes of bauxite to third parties in the fourth quarter, 1% lower than the same period of 2023. Alumina Alumina production of 2.0 million tonnes was 4% higher than the fourth quarter of 2023. Gas supplies to our Gladstone operations from the third-party operated Queensland Gas Pipeline are now meeting 100% of our requirements, following a breakage of this pipeline in March. As the result of sanction measures by the Australian Government, Rio Tinto has taken on 100% of capacity of Queensland Alumina Limited (QAL) for as long as the sanctions continue. This results in use of Rusal’s 20% share of capacity by Rio Tinto under the tolling arrangement with QAL. This additional output is excluded from the production tables in this report as QAL remains 80% owned by Rio Tinto and 20% owned by Rusal. Aluminium Aluminium production of 0.8 million tonnes was 1% lower than the fourth quarter of 2023. At our New Zealand Aluminium Smelter (NZAS) production continued to ramp-up following a previous call from Meridian Energy to reduce its electricity usage in August, for which we are compensated. As previously reported, we expect the ramp-up to run through to the second quarter of 2025. At Kitimat, our energy supply and production was impacted by lower reservoir levels. We completed the previously announced acquisition of Sumitomo Chemical Company’s (SCC’s) 20.64% interest in NZAS on 1 November 2024 and now fully own the Tiwai Point aluminium smelter. We also completed the previously announced acquisition of SCC’s 2.46% stake in Boyne Smelters Limited (BSL). The completion of this transaction, along with the recently completed acquisition of Mitsubishi’s 11.65% stake in BSL, brings Rio Tinto’s total interest in BSL to 73.5%. Production is reported including these changes in ownership from 1 November 2024. Average realised aluminium prices including premiums for value-added products (VAP) increased 4% to $2,834 per tonne in 2024 (2023: $2,738 per tonne). The LME price increased by 8% to $2,419 per tonne (2023: $2,250 per tonne), whilst the mid-west premium duty paid declined 17% to $427 per tonne in 2024 (2023: $512 per tonne), which is 59% of our total volumes (57% in 2023). Our VAP sales remained at 46% of primary metal sold in 2024 (2023: 46%). Product premiums for VAP sales decreased, averaging $295 per tonne of VAP sold (2023: $354 per tonne). On 4 December, we announced a partnership agreement with the Swedish investment company Vargas, Mitsubishi Corporation and other international and local industry partners to study a low-carbon aluminium greenfield opportunity in Finland. We will provide the Arctial partnership with access to our proven industry- leading AP60 technology and assist in what would be the first AP60 deployment in an aluminium smelter outside Quebec. As a first step, Arctial will conduct a feasibility study and environmental impact assessment. Rio Tinto | Fourth quarter operations report 13

Recycled aluminium Rio Tinto’s share of production from Matalco was 58 thousand tonnes in the fourth quarter (116 thousand tonnes on a 100% basis), as production continued to be impacted by market conditions in North America. Full year 2024 production from Matalco was 264 thousand tonnes (528 thousand tonnes on a 100% basis). Rio Tinto | Fourth quarter operations report 14

Copper Rio Tinto share of production (‘000 tonnes) Q4 2024 vs Q4 2023 vs Q3 2024 2024 vs 2023 Mined copper Kennecott 31.2 -35 % +14 % 123.4 -19 % Escondida 104.8 +46 % +16 % 358.7 +20 % Oyu Tolgoi (66% basis) 43.8 +63 % +33 % 141.9 +28 % Total mined copper production 179.8 +23 % +19 % 624.0 +11 % Total mined copper production (consolidated basis1) 202.4 +26 % +21 % 697.1 +13 % Refined copper Kennecott2 55.4 +73 % +30 % 193.2 +78 % Escondida 13.3 -5 % +13 % 55.1 -17 % 1 Includes Oyu Tolgoi and Kennecott on a 100% consolidated basis, and Escondida on an equity share basis. 2 We continue to process third party concentrate to optimise smelter utilisation, including 8.7 thousand tonnes of cathode produced from purchased concentrate in 2024. Purchased and tolled copper concentrates are excluded from reported production figures and production guidance. Sales of cathodes produced from purchased concentrate are included in reported revenues. Kennecott Mined copper production was 35% lower than the fourth quarter of 2023. This was primarily due to reduced head grade caused by geotechnical instabilities in the pit wall that impacted the mining sequence and increased the usage of lower grade stockpiled ore, as first identified in our Second Quarter Operations Review. As detailed at our Investor Seminar in December, we have revised our mine plan with smaller benches, lower bench stack height and step outs, and increased waste movement to unload the area around the faults. We are focusing on our overheads and contractor management costs while identifying efficiencies in our truck and excavator fleet. We are also supplementing our smelter with third party concentrate (5.7 thousand tonnes in the fourth quarter) to maintain throughput. Production will be impacted in 2025 and 2026 in line with the annualised mine production rate from the last three quarters of 2024, with slight improvement expected in 2026. Meanwhile, we continue to review future options for the open pit and underground. Refined copper production was 73% higher than the fourth quarter of 2023, following the rebuild of the smelter and refinery in 2023. Refined production was 30% higher than the third quarter, due to good smelter performance following the annual planned shutdown of the concentrator and smelter in July. Escondida Mined copper production was 46% higher than the fourth quarter of 2023 due to higher ore grades being fed to the concentrators (1.06% versus 0.77%) driven by access to a higher grade zone. Refined copper production was 5% lower than the same quarter of last year, given reduced oxide leach volumes, with lower grades being stacked during 2024 and integration of the Full SaL project. However, production in the fourth quarter was 13% higher than the prior quarter due to higher grade of the stacked ore. Full SaL continues to progress, with first salt addition achieved this quarter and ramp up expected during 2025. We continue to work with our joint venture partners on Escondida growth options. Oyu Tolgoi Mined copper production increased 63% from the fourth quarter of 2023 given the ramp-up in production, and higher grade, from the underground mine. Production was 33% higher than the previous quarter due to the ongoing commissioning of the conveyor to surface, with first ore on the belt delivered in October. Open pit operations also benefited from an increase in ore grade. Rio Tinto | Fourth quarter operations report 15

We have opened a total of 124 drawbells from Panel 0 of the underground mine, including four during the fourth quarter. During the quarter, we delivered 2.1 million tonnes of milled ore from the underground mine at an average copper head grade of 1.96% and 8.9 million tonnes from the open pit with an average grade of 0.43%. The ramp-up remains on track to reach 500 thousand tonnes of copper per year (100% basis and stated as recoverable metal) for the underground and open pit mines for the years 2028 to 20361. Production is scheduled to come from Panel 0 and Panel 2 in 2025. We are also planning to undertake development work in Panel 1. Panel 1 sits partially on a mining licence subject to a joint venture between Entrée Resources and Oyu Tolgoi. We are working closely with all stakeholders towards a longer-term solution for mining in this joint venture area. In November, we successfully concluded our Collective Agreement negotiations, marking a historic milestone as the first agreement involving two trade unions at the operation. The agreement will remain in effect for the next three years. Rio Tinto | Fourth quarter operations report 16 1 The 500 thousand tonnes per annum copper production target (stated as recoverable metal) for the Oyu Tolgoi underground and open pit mines for the years 2028 to 2036 was previously reported in a release to the ASX dated 11 July 2023 “Investor site visit to Oyu Tolgoi copper mine, Mongolia”. All material assumptions underpinning that production target and those production profiles continue to apply and have not materially changed.

Although these challenges will persist into 2025, we expect they will be offset by improved productivity in the mine. Shipments were 3% lower than the fourth quarter of 2023 driven by reduced concentrate production. Annual rail haulage was 36.4 million tonnes, 7% higher than in 2023, driven by continued operational improvements to meet increasing third-party and IOC demand. Our focus going forward is to stabilise the operation and achieve safe, cost-effective and consistent production. Borates Borates production in the fourth quarter was 18% higher than the corresponding period of 2023 due to a scheduled shut in the prior period. Iron and Titanium Titanium dioxide slag production was 14% lower than the fourth quarter of 2023 reflecting a planned shutdown at our RTIT Quebec Operations. A furnace reconstruction continues in Quebec, where we continue to operate six out of nine furnaces. Three out of four furnaces are operating at Richards Bay Minerals (RBM). Diamonds At Diavik, carat production was 18% higher than the fourth quarter of 2023. Production continues to ramp up from a subsidence event in July that limited underground ore deliveries. On 3 October, we announced that the Diavik mine has safely completed the development and construction of Phase 1 of the A21 underground mine, now moving the underground mine into commercial production.

Exploration and evaluation Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in 2024 was $935 million, compared with $855 million in 2023 (excluding Simandou). Approximately 25% of the spend was by central exploration, 23% by Minerals (with the majority focusing on lithium), 36% by Copper, 14% by Iron Ore and 2% by Aluminium. In 2024, all qualifying expenditure relating to Simandou is being capitalised. Qualifying expenditure on the Rincon project has been capitalised since 1 July 2024. Exploration highlights Rio Tinto has a strong portfolio of projects with activity in 17 countries across eight commodities in early exploration and studies stages. The bulk of the exploration expenditure in the fourth quarter focused on copper in Angola, Chile, Colombia, Papua New Guinea, Peru, the US and Zambia, nickel in Finland, lithium in Canada, Rwanda, and Australia, potash in Canada, diamonds in Angola, heavy mineral sands (HMS) in South Africa and rutile-graphite in Malawi. The Rio Tinto operated Nuevo Cobre joint venture copper project in Chile continues to make good progress with permitting advancing alongside ongoing geological field programs.
