Rio Tinto releases third quarter production results 16 October 2024 Rio Tinto Chief Executive Jakob Stausholm said: “We continue to strengthen our operations, with the roll-out of the Safe Production System delivering consistent production at our Pilbara iron ore business and a step change from our Australian bauxite mines. We are building on this, with more work to do across our global portfolio. “We progressed our major projects to deliver profitable organic growth. We are on track for first production from our Simandou high-grade iron ore project next year and first lithium from the Rincon starter plant by the end of this year. Meanwhile the ramp-up of copper production continues at the Oyu Tolgoi underground mine. “We announced the acquisition of Arcadium Lithium, bringing a world-class lithium business alongside our leading aluminium and copper operations to supply materials needed for the energy transition. This is aligned with our strategy and our disciplined capital allocation framework, increasing our exposure to a high-growth, attractive market at the right point in the cycle. “The decarbonisation of our business remains a priority and is progressing well. We took another important step in securing a long-term future for the Boyne Smelter, announcing a partnership with the Queensland Government to support investment in renewable energy projects. “Our long-term pathway to deliver profitable growth and create shareholder value remains clear, as we progress our business in line with our four objectives.” Production1 Q3 2024 vs Q3 2023 vs Q2 2024 9 MTHS 2024 vs 9 MTHS 2023 Pilbara iron ore shipments (100% basis) Mt 84.5 +1 % +5 % 242.9 -1 % Pilbara iron ore production (100% basis) Mt 84.1 +1 % +6 % 241.5 -1 % Bauxite Mt 15.1 +8 % +3 % 43.2 +9 % Aluminium2 kt 809 -2 % -2 % 2,459 +1 % Mined copper (consolidated basis) kt 168 -1 % -2 % 495 +8 % Titanium dioxide slag kt 263 +7 % +11 % 755 -10 % IOC3 iron ore pellets and concentrate Mt 2.1 -11 % -3 % 6.9 -1 % 1 Rio Tinto share unless otherwise stated. 2 Includes primary aluminium only. 3 Iron Ore Company of Canada. Q3 2024 operational highlights and other key announcements • Our all injury frequency rate (AIFR) for the third quarter was 0.40, an increase from the second quarter of this year (0.31) and the third quarter of 2023 (0.35). We continue to prioritise learning from safety incidents to improve the effectiveness of our critical controls. The health, safety and wellbeing of our people and partners remains at the heart of everything we do. • We are on track to deliver our ambition to grow overall copper equivalent production (based on long- term consensus pricing) by around 3% of compound annual growth from 2024 to 2028 from our existing portfolio and projects already in execution. • In the Pilbara, we produced 84.1 million tonnes (Rio Tinto share 71.0 million tonnes) in the third quarter, 1% higher than the corresponding period of 2023. Productivity gains continue to offset ore depletion. Shipments of 84.5 million tonnes (Rio Tinto share 72.5 million tonnes) were also 1% higher than the third quarter of 2023. • Bauxite production of 15.1 million tonnes was 8% higher than the third quarter of 2023. The improvement continues to be driven by higher plant availability and utilisation rates owing to the implementation of the Safe Production System, especially at our Amrun mine at Weipa, which is operating above nameplate capacity. • Aluminium production of 0.8 million tonnes was 2% lower than the third quarter of 2023. Production at our New Zealand Aluminium Smelter (NZAS) was impacted by a call from Meridian Energy to reduce its electricity usage by 185 MW from early August. The call for reduced usage, for which we are compensated, has now ended and the smelter ramp-up commenced in late September. The ramp-up is expected to run through to the second quarter of 2025. Notice to ASX/LSE Rio Tinto | Third quarter operations report 1 EXHIBIT 99.1
• Mined copper production of 168 thousand tonnes (consolidated basis) was 1% lower than the third quarter of 2023. ◦ Kennecott was 44% lower than the third quarter of 2023. As we identified in our second quarter operations review, highwall movement was monitored along two major faults during that period. This movement has limited our ability to access the primary ore face on the south wall and is increasing the need to supplement feed to the concentrator with lower grade stockpile ore, impacting mined copper production by approximately 50 thousand tonnes in 2024. A group of experts, both internal and external, reworked Kennecott’s mine plan and the results were assessed during the quarter. The highwall movement will continue to restrict ore deliveries from the primary ore face and impact mined copper production in 2025 and 2026. We are working through this change in mining sequence and will provide a further update at our Investor Seminar in December. ◦ Escondida was 15% higher than the third quarter of 2023 due to higher ore grades being fed to the concentrators (1.00% versus 0.85%) in line with the mining sequence, together with increased recovery. ◦ Oyu Tolgoi was 19% higher than the third quarter of 2023 due to the ramp-up in production and higher grade from the underground mine. However, production was 5% lower than the previous quarter mainly due to planned maintenance at the concentrator and adverse weather impacting open pit operations. Production from the underground mine was marginally impacted by a minor delay to the start of commissioning of the conveyor to surface, with first ore on belt now expected in the second half of October. The underground mine delivered a copper head grade of 2.05% (vs 1.73% in the third quarter of 2023) with an overall copper head grade of 0.67% (vs 0.52%). • Titanium dioxide slag production was 7% higher than the third quarter of 2023 due to improved smelter stability and performance. A furnace reconstruction continues at our RTIT Quebec Operations, and we continue to operate six out of nine furnaces in Quebec and three out of four at Richards Bay Minerals (RBM). • IOC production was 11% lower than the third quarter of 2023 due to an 11-day site-wide shutdown following forest fires in mid-July. This resulted in a revised mine plan and maintenance schedule, leading to a reduction in our full year iron ore pellets and concentrate production guidance to 9.1 to 9.6 million tonnes (previously 9.8 to 11.5 million tonnes). • In the third quarter, deployment of the Safe Production System (SPS) continued, now reaching 28 sites (an increase of two from the second quarter). We continue to deepen the maturity of SPS and are on track to deliver a 5 million tonne year-on-year production uplift at Pilbara Iron Ore. • On 17 July, we announced the appointment of Katie Jackson to lead the Copper business, succeeding Bold Baatar, who as of 1 September, has moved to the role of Chief Commercial Officer. • We hosted a site visit for the financial community to our Aluminium and Iron & Titanium operations in Quebec, Canada during September. In the management presentation, we set out a clear pathway to raise both the EBITDA margin and Return on Capital Employed (ROCE) for our Aluminium business by five percentage points by 2030. We also set out a targeted increase in ROCE at our Iron & Titanium business of nine percentage points by 2030 and a pathway to reach concentrate capacity of 23 million tonnes (100% basis) of high-grade iron ore at IOC. Presentations by management also covered technology, decarbonisation and markets. • Subsequent to the end of the quarter, 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. Subject to satisfaction of the outstanding conditions, the transaction is expected to close in mid-2025. All figures in this report are unaudited.

SP10 levels are expected to remain elevated until replacement projects are delivered. This guidance remains subject to the timing of approvals for planned mining areas and heritage clearances. • Iron ore shipments and bauxite production guidance remain subject to weather impacts. Operating costs • 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. • Guidance for 2024 copper C1 unit costs is unchanged at 140 to 160 US cents/lb. Rio Tinto | Third quarter operations report 3
Investments, growth and development projects • Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in the first nine months of 2024 was $692 million, compared with $613 million in the first nine months of 2023 (excluding Simandou). Approximately 24% of the spend was by central exploration, 30% by Minerals (with the majority focusing on lithium), 31% by Copper, 14% by Iron Ore and 1% 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 80% complete. During the quarter, we finalised commissioning of the autonomous haul trucks and completed the Paraburdoo upgrade works. We continue to focus on construction of the greenfield crushing and screening plant and Paraburdoo plant tie-in, with first ore from that new system on plan for 2025. • We continue to advance our next tranche of Pilbara mine replacement studies including Hope Downs (Hope Downs 2 and Bedded Hilltop), Brockman 4 (Brockman Syncline 1), Greater Nammuldi and West Angelas projects. During the quarter, funding approval for full execution was obtained for the Hope Downs replacement project and the environmental and heritage approvals are progressing. Project timelines remain subject to timing of approvals and heritage clearances with the Greater Nammuldi project remaining divergent from 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 at our Coastal Water desalination project have commenced, with mobilisation of the earthworks contractor. 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 of the bucketwheel reclaimers and associated infrastructure within the Parker Point Stockyard at our Dampier Port. Commissioning of all replacement reclaimers is planned to be completed by the first half of 2029. Oyu Tolgoi underground project • Ventilation Shafts 3 and 4 were commissioned during the quarter with fresh air now being drawn into the underground mine. • Construction work on the conveyor to surface was 98% complete at the end of the quarter and, after a minor delay to the start of the commissioning, we expect first ore on the belt in the second half of October. • Construction works for the concentrator conversion is ongoing. Commissioning is expected to be progressively completed from the fourth quarter of 2024 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 • As we reported in our Second Quarter Operations Review, all conditions for Rio Tinto’s investment to develop the Simandou high-grade iron ore deposit in Guinea were satisfied, with the transaction closing in July. • The Simfer mine1 is on track to deliver first production 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, progress continues on plan, despite productivity being impacted by wet weather during the quarter. Mine process plant installation early works and non-process infrastructure contracts were awarded during the period. First blasting activities on our mining concession also took place. The two initial crushers required to produce first ore for commissioning have arrived in Guinea. Rio Tinto | Third quarter operations report 4
• During the third quarter, a number of the critical milestones for 2024 have been achieved for the Simfer infrastructure scope. The laying of sleepers and track has commenced, with progress expected to accelerate next quarter with the arrival of track laying locomotives. For the bridge construction works, we have completed the piers and commenced laying bridge platforms. Tunnel excavation activity is now more than 50% complete and activities at the port have advanced, with transhipment vessel (TSV) wharf construction and car dumper excavation commencing. • The current total workforce across all the Simfer scope of mine, rail and port is 10,800 with 85% national Guinean participation. Other key projects and exploration and evaluation • At Complexe Jonquière in Quebec, the AP60 expansion project remains on schedule. Construction activities progressed, with assembly of the gas treatment centre commencing during the quarter. 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, the Apache Stronghold filed a petition to the U.S. Supreme Court requesting to hear its case to stop the land exchange between Resolution Copper and the federal government. The San Carlos Apache Tribe also filed a second petition with the U.S. Supreme Court, asking the Court to review a decision by the Arizona Supreme Court regarding a water discharge permit issued to Resolution Copper by the State of Arizona. We continue to progress the Final Environmental Impact Statement with the United States Forest Service, but they have yet to advise on the date of re- publication. We also advanced partnership discussions with 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. • We continue to work with the Traditional Owners to progress the Winu copper-gold project, which remains subject to all of the required approvals. Drilling, studies and fieldwork to advance the key environmental permitting and Project Agreement negotiations with Nyangumarta and the Martu 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. • At the Rincon lithium project in Argentina, development of the 3,000 tonne per year lithium carbonate starter plant continues to progress, with construction activities now over 70% complete. Commissioning of medium and low voltage substations has commenced and we continue to expect first production from the starter plant by the end of 2024. The feasibility study for full-scale operation is nearing completion, with a final investment decision expected in the fourth quarter of 2024. We continue to engage with communities, the province of Salta and the Government of Argentina to ensure an open and transparent dialogue with stakeholders about the works underway. • We continue to believe that the Jadar project has the potential to be a world-class lithium-borates asset that could act as a catalyst for the development of other industries and thousands of jobs for current and future generations in Serbia. The decision that allowed the reinstatement of the spatial plan for the Jadar project by Serbia's Constitutional Court in July has been followed by the application process for obtaining the Exploitation Field Licence (EFL) being initiated, with a submission planned for December 2024. The EFL is essential for commencing fieldwork, including detailed geotechnical investigations, while cultural heritage and environmental surveys have resumed. The Environmental Impact Assessment process has also begun, with scoping and content for the mine currently under public consultation. This step formalises discussions through legally mandated consultations, which the project supports, to encourage an open, fact-based dialogue. Rio Tinto | Third quarter operations report 5
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. Rio Tinto | Third quarter operations report 6
Sustainability highlights During the third quarter, we continued to work on implementation of the remaining Everyday Respect recommendations. Aligned to the final recommendation, Elizabeth Broderick & Co conducted their independent progress review, visiting our sites and obtaining insight into the daily experience of our people through facilitated listening groups and surveys. We now await their final report and will make this publicly available during the fourth quarter of 2024. Their findings will enable us to understand where we have made progress in our cultural journey and where we need to focus to continue our momentum in creating a safe, respectful and inclusive workplace. As part of our commitment to contributing to nature positive outcomes globally and supporting the energy transition, we published an updated position statement on reform to Australia's Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). We believe reform should deliver improved outcomes for Australia's national environmental and culturally significant places and species, and more efficient and effective approvals processes. The full position statement can be found here. Communities & Social Performance (CSP) Rio Tinto assets undertook a range of community and social investment activities focused on advancing community health and wellbeing, and conserving and celebrating cultural heritage. Key highlights from the third quarter include: 1 July 2024 | Rio Tinto partners with PinkDrive to bring health screening to communities 3 July 2024 | Rio Tinto builds 10 hectares of park in the heart of the capital city of Mongolia 9 July 2024 | Launch and celebration of the AIATSIS Centre for Australian Languages 10 July 2024 | Rio Tinto contributes A$40 million towards Paraburdoo and Tom Price Hospitals 19 July 2024 | Rio Tinto IOC donates CAN$200,000 to support the people and communities of Labrador West 30 Aug 2024 | Rio Tinto IOC celebrates 70 years in the Labrador Trough 16 Sept 2024 | Pilbara Aboriginal artists share cultural stories for the 19th Colours of our Country exhibition Climate change, product stewardship and our value chain On 15 August, we announced that we will work with the Queensland Government to safeguard a pillar of the State’s heavy industrial manufacturing base around Gladstone under a partnership to support investment in renewable energy projects. The agreement represents an important step towards securing a long-term future for Australia's second-largest aluminium smelter, Boyne Smelters Limited (BSL), and thousands of jobs in central Queensland supported by the operations. We continue to engage with the Federal Government on supportive industrial policy to help sustain Australia’s green aluminium sector for the future. This quarter, we also shared our project to develop Pongamia seed farms as part of a new biofuels pilot. The pilot aims to determine if Pongamia seed oil can contribute to our renewable diesel needs while potentially contributing to the growth of a new biofuel sector in Australia. We are in the final stages of acquiring approximately 3,000 hectares of cleared land near Townsville in northern Queensland to establish farms to study growth conditions and measure seed oil yields.

Our markets The global economy is expected to grow moderately this year, similar to last year, while industrial production is still on a gradual recovery. Market sentiment improved in late September given a deeper-than-expected interest rate cut by the US Federal Reserve, followed by the announcement of monetary stimulus measures in China that signalled a reprioritisation on economic growth. Geopolitical tensions and trade barriers remain near-term global economic risks. • China’s economic recovery has been uneven, prompting more government support to sustain growth. Manufacturing and exports have outperformed, while the property market downturn continues, amidst concerns over local government debt and low consumer confidence. As the economy transitions from the property sector to new growth areas, future commodity demand will turn more reliant on advanced manufacturing, including electric vehicles, and power infrastructure (generation, transmission and distribution, and storage). • The US economy is settling into a sustainable pace of growth. The labour market indicated that pay and job growth are slowing but strong household balance sheets are providing support to consumer spending. Manufacturing and housing activity was depressed but could benefit from the onset of the Federal Reserve’s interest rate cut cycle. • The eurozone outlook continues to be uncertain, with uneven growth across countries and consumption remaining subdued. The manufacturing PMI during the quarter indicated that the recovery of the industrial sector is slow, while sentiment indicators point to similar weakness, amidst cooling wage growth and persistent services inflation. • Iron ore prices increased by 1% over the quarter, while the average monthly price in the third quarter of $99/dmt (Platts CFR 62% Fe index) was 11% lower than the second quarter. In response to lower prices for most of the period, supply from higher cost suppliers declined compared to the previous quarter. There were headwinds to iron ore demand in the major steel producing regions at the start of the quarter; however, Chinese demand improved in September following completion of maintenance at steel mills. Iron ore inventories at Chinese ports were flat, while China’s steel exports fell slightly during the quarter, but remained higher than a year ago. • The LME aluminium price increased by 5% over the quarter, while the average price decreased by 5% from the second quarter, to $2,382/t. Ex-China, aluminium semi-fabricated shipments were broadly stable into the third quarter. However, extrusions demand remained weak on low activity in the construction sector. Firm demand for aluminium in the packaging sector supported shipments of rolled aluminium products. Chinese aluminium production rates are close to the capacity cap of ~45 million tonnes, while production rates ex-China were lowered at the start of the third quarter. Overall, the global market remained broadly balanced in the third quarter with inventories at a low level compared to historical norms. Alumina prices were elevated over the quarter given refinery disruptions ex-China, with the price trading at a high ratio to the LME aluminium price. Sustained bauxite tightness supported strong seaborne bauxite prices to China. • The LME copper price increased by 3% over the quarter, while the average price was down 6% quarter-on-quarter to $4.18/lb. Pent up demand in China returned in the third quarter, as fabricators held back from buying amid high prices in the previous quarter. Demand in the rest of world was mixed, with strong performance in developed Asia offset by weakness in Europe. Globally, exchange inventories remain up year-to-date but have started declining since August, thanks to improved demand. Rate cuts in the US and announced stimulus in China towards the end of the quarter helped boost sentiment and led to a price rally. The copper concentrate market remains tight as growth in smelting capacity significantly exceeds concentrate supply growth, which is keeping spot treatment and refining charges (TCRCs) low. • Lithium demand continues to grow with electric vehicle (EV) sales rising 20% year on year over the first eight months despite slower-than-expected uptake from Europe and the US. On the supply side, projects continue to develop, while some closures in Australia and China have also been announced given soft prices, which continued to fall over the third quarter. Market fundamentals for lithium remain attractive over the longer term, given increasing EV penetration rates driven by the energy transition. • Underlying demand for titanium feedstock has stabilised with paint and coatings producers reporting flat to slightly rising sales volumes. Mid-stream utilisation rates have risen which is increasing consumption of feedstock, however this demand is currently being met from inventory built during 2023. Rio Tinto | Third quarter operations report 8
• The borates market has been stable during the third quarter. Demand has improved in South American agriculture and industrial-related applications (textile, fibreglass). Demand from the US construction sector continues to be robust, while demand from China’s construction sector remains weak. Rio Tinto | Third quarter operations report 9

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 84.1 million tonnes (Rio Tinto share 71.0 million tonnes) in the third quarter, 1% higher than the corresponding period of 2023. Productivity gains continue to offset ore depletion. Shipments of 84.5 million tonnes (Rio Tinto share 72.5 million tonnes) were 1% higher than the third quarter of 2023. SP10 volumes accounted for 19%1 of shipments in the third quarter, slightly higher than the first half of 2024 (17%). 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. Approximately 11% of sales in the first nine months of 2024 were priced with 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 26% of sales in the nine months to September 2024 were made on a free on board (FOB) basis, with the remainder sold including freight. On 19 July, we celebrated the shipment of 4 billion tonnes of iron ore from the Pilbara to China. The shipment was loaded at Dampier Port, bound for China Baowu Steel Group, the world’s top steel producer. This milestone comes 51 years after the first shipment from Dampier Port to China's Shanghai No.1 Steel Mill, which has since become part of China Baowu.

China Portside Trading Our iron ore portside sales in China were 20.4 million tonnes in the first nine months of 2024 (17.5 million tonnes of sales in the first nine months of 2023). At the end of September, inventory levels are 8.1 million tonnes, including 5.6 million tonnes of Pilbara product. In the first nine months of 2024 approximately 90% of our portside sales were either screened or blended in Chinese ports (87% in the first nine months of 2023). 1 Based on total Pilbara shipments on a 100% basis.

Aluminium Rio Tinto share of production (‘000 tonnes) Q3 2024 vs Q3 2023 vs Q2 2024 9 MTHS 2024 vs 9 MTHS 2023 Bauxite 15,100 +8 % +3 % 43,242 +9 % Bauxite third party shipments 11,120 +16 % +4 % 30,307 +14 % Alumina 1,770 -7 % +6 % 5,310 -5 % Aluminium 809 -2 % -2 % 2,459 +1 % Recycled aluminium 62 n/a -10 % 206 n/a Bauxite Bauxite production of 15.1 million tonnes was 8% higher than the third quarter of 2023. The improvement continues to be driven by higher plant availability and utilisation rates owing to the implementation of the Safe Production System, especially at our Amrun mine at Weipa, which is operating above nameplate capacity. We shipped 11.1 million tonnes of bauxite to third parties in the third quarter, 16% higher than the same period of 2023. Alumina Alumina production of 1.8 million tonnes was 7% lower than the third quarter of 2023 as production at our Gladstone operations continues to be impacted by the breakage of the third-party operated Queensland Gas Pipeline in March. Gas supplies are currently meeting ~95% of our requirements and are expected to return to normal levels by the end of 2024. 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 2% lower than the third quarter of 2023. Production at our New Zealand Aluminium Smelter (NZAS) was impacted by a call from Meridian Energy to reduce its electricity usage by 185 MW from early August. The call for reduced usage, for which we are compensated, has now ended and the smelter ramp-up commenced in late September. The ramp-up is expected to run through to the second quarter of 2025. Rio Tinto’s previously announced acquisition of Mitsubishi Corporation’s 11.65% interest in Boyne Smelters Limited (BSL) completed on 30 September 2024. Rio Tinto’s interest in BSL is now 71.04%. Previously announced acquisitions by Rio Tinto of Sumitomo Chemical Company’s (SCC) 2.46% stake in BSL, and SCC’s 20.64% interest in NZAS, continue to progress through various conditions precedent. Recycled aluminium Rio Tinto’s share of production from Matalco was 62 thousand tonnes in the third quarter (125 thousand tonnes on a 100% basis), as production was impacted by market conditions in North America. Full year 2023 production from Matalco was 582 thousand tonnes (on a 100% basis) of recycled aluminium products. Rio Tinto | Third quarter operations report 12
Copper Rio Tinto share of production (‘000 tonnes) Q3 2024 vs Q3 2023 vs Q2 2024 9 MTHS 2024 vs 9 MTHS 2023 Mined copper Kennecott 27.4 -44 % -15 % 92.1 -11 % Escondida 90.4 +15 % +5 % 253.9 +11 % Oyu Tolgoi (66% basis) 33.0 +19 % -5 % 98.1 +17 % Total mined copper production 150.8 -3 % -2 % 444.2 +7 % Total mined copper production (consolidated basis1) 167.8 -1 % -2 % 494.7 +8 % Refined copper Kennecott 42.5 +129 % -11 % 137.8 +80 % Escondida 11.8 -24 % -22 % 41.8 -21 % 1 Includes Oyu Tolgoi and Kennecott on a 100% consolidated basis, and Escondida on an equity share basis. Kennecott Mined copper production was 44% lower than the third quarter of 2023. As we identified in our second quarter operations review, highwall movement was monitored along two major faults during that period. This movement has limited our ability to access the primary ore face on the south wall and is increasing the need to supplement feed to the concentrator with lower grade stockpile ore, impacting mined copper production by approximately 50 thousand tonnes in 2024. A group of experts, both internal and external, reworked Kennecott’s mine plan and the results were assessed during the quarter. The highwall movement will continue to restrict ore deliveries from the primary ore face and impact mined copper production in 2025 and 2026. We are working through this change in mining sequence and will provide a further update at our Investor Seminar in December. Refined copper production was 129% higher than the third quarter of 2023, following the rebuild of the smelter and refinery in the prior period, and 11% lower than the second quarter, due to the annual planned shutdown of the concentrator and smelter in July. Escondida Mined copper production was 15% higher than the third quarter of 2023 due to higher ore grades being fed to the concentrators (1.00% versus 0.85%) in line with the mining sequence, together with increased recovery. Refined copper production was 24% lower than the same quarter of last year, given lower oxide leach performance due to lower grades being stacked during 2024, and 22% lower than the second quarter due to the installation and upgrading of infrastructure related to the Full SaL enhanced recovery project. During August, Escondida successfully concluded wage negotiations with Union 1 at the operation. Oyu Tolgoi Mined copper production increased 19% from the third quarter of 2023 due to the ramp-up in production, and higher grade, at the underground mine. However, production was 5% lower than the previous quarter mainly due to planned maintenance at the concentrator and adverse weather impacting open pit operations. Production from the underground mine was marginally impacted by a minor delay to the start of commissioning of the conveyor to surface, with first ore on the belt now expected in the second half of October. We have opened a total of 120 drawbells from Panel 0 of the underground mine, including six during the quarter. During the quarter, we delivered 1.5 million tonnes of milled ore from the underground mine at an average copper head grade of 2.05% and 7.4 million tonnes from the open pit with an average grade of 0.39%. 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. During the third quarter, we entered negotiations on a new Collective Labour Agreement. Our current agreement expires in April 2025. Rio Tinto | Third quarter operations report 13 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.

This resulted in a revised mine plan and maintenance schedule, leading to a reduction in our full year iron ore pellets and concentrate production guidance to 9.1 to 9.6 million tonnes (previously 9.8 to 11.5 million tonnes). Shipments were 4% higher than the third quarter of 2023 driven by inventory movements. Borates Borates production in the third quarter was 1% lower than the corresponding period of 2023 due to planned maintenance at the refinery in August 2024. Iron and Titanium Titanium dioxide slag production was 7% higher than the third quarter of 2023 due to improved smelter stability and performance. A furnace reconstruction continues at our RTIT Quebec Operations, and we continue to operate six out of nine furnaces in Quebec and three out of four at Richards Bay Minerals (RBM). Diamonds At Diavik, carat production was 28% lower than the third quarter of 2023. Production was impacted by a subsidence event in July that limited underground ore deliveries. Subsequent to the end of the quarter, we announced that the Diavik mine has safely completed the development and construction of Phase 1 of the A21 underground, with the mine moving into commercial production. We expect to complete Phase 2 and fully mine the A21 underground before closure in 2026. In early October, we launched the 2024 Beyond RareTM Tender with a special collection of rare pink, red, violet and yellow diamonds. Rio Tinto | Third quarter operations report 14
Exploration and evaluation Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in the first nine months of 2024 was $692 million, compared with $613 million in the first nine months of 2023 (excluding Simandou). Approximately 24% of the spend was by central exploration, 30% by Minerals (with the majority focusing on lithium), 31% by Copper, 14% by Iron Ore and 1% 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 18 countries across eight commodities in early exploration and studies stages. The bulk of the exploration expenditure in the third quarter focused on copper in Chile, Peru, Kazakhstan, Australia, Colombia and the US, nickel in Brazil and Canada, lithium in Canada, the US, Chile, Rwanda, Kazakhstan, Brazil and Australia, potash in Canada, diamonds in Angola, heavy mineral sands (HMS) in South Africa and rutile-graphite in Malawi.
