Rio Tinto releases fourth quarter production results 19 January 2021 Rio Tinto Chief Executive Jakob Stausholm, said: “We have delivered a strong safety and operational performance in the face of the significant global challenges of COVID-19. Our 2020 performance reflects the resilience of the business, and the commitment and flexibility of our employees, customers, communities and host governments. "We are working to restore trust with the Puutu Kunti Kurrama and Pinikura (PKKP) people. Some important progress has been made as set out in the joint statement issued in December following a meeting between the PKKP and Rio Tinto boards. We are also developing additional measures to strengthen our partnerships with Traditional Owners, including a commitment to modernise and improve agreements, particularly in the Pilbara. More broadly, we are determined to improve Rio Tinto’s approach to stakeholder engagement globally by embedding a more inclusive approach that strengthens our overall thinking, decision-making and performance. However, I do not underestimate the time and effort it will take, genuinely working together with our partners, in order for Rio Tinto to drive the changes necessary to help restore trust and rebuild our reputation. “Safe and well-run operations, together with world-class assets and a strong balance sheet, leave Rio Tinto well placed to generate superior returns for shareholders, invest in sustaining and growing our portfolio, while continuing to pay taxes and royalties in our host communities and make a broader contribution to society, including employment and procurement."

Health and safety remains our top priority as we maintain use of the critical controls that protect our employees and the local communities with the resurgence of COVID-19 in several regions where we operate. Our all injury frequency rate (AIFR) improved by more than 10% for 2020 versus 2019 (0.42), demonstrating our ability to adapt to changing conditions. • Pilbara iron ore achieved a strong performance across the network in 2020, despite impacts from Cyclone Damien in the first quarter and COVID-19 disruptions which also resulted in the deferral of maintenance to the second half. Shipments of 330.6 million tonnes (100% basis) were 1% higher than 2019 and production of 333.4 million tonnes (100% basis), 2% higher than 2019. This was underpinned by record total material moved, 7% higher than the previous record in 2019. • Bauxite production of 56.1 million tonnes was 2% higher than 2019 supported by the ramp-up of the expansion at the CBG mine in Guinea, and steady performance at the Pacific mines. • Aluminium production of 3.2 million tonnes was in line with 2019, with lower volumes from the curtailment of Line 4 at the Tiwai Point aluminium smelter in New Zealand and from the Kitimat smelter pot relining campaign, offset by the ramp-up of the Becancour smelter in Quebec. • On 14 January 2021, we announced a new electricity agreement had been reached with Meridian Energy that allows New Zealand’s Aluminium Smelter (NZAS) to continue operating the Tiwai Point aluminium smelter until December, 2024. Notice to ASX/LSE 1 EXHIBIT 99.1

• Mined copper was above the guidance range, but 9% lower than 2019 due to lower grades at Kennecott as a result of planned pit sequencing and Oyu Tolgoi production phasing. The commercial and operational teams at Kennecott Utah achieved approximately 60,000 dry metric tonnes of copper concentrate sales in the fourth quarter to partly mitigate the impact of the delayed re-start of the smelter, which became fully operational during October. • On 16 December, we confirmed the definitive estimate of cost and schedule for Panel 0 of the Oyu Tolgoi underground project in Mongolia, with sustainable production expected to commence in October 2022 and development capital of $6.75 billion1, in line with previously announced ranges. Rio Tinto considers that additional milestones need to be met in order to ensure that the project can commence caving operations in 2021, including: outstanding government approvals; funding; and, a power solution. Further information can be found in the Investments, growth and development projects section below. • Titanium dioxide slag production of 1.1 million tonnes was 7% lower than 2019 due to COVID-19 restrictions in Quebec and South Africa, lower market demand and operational disruptions at Richards Bay Minerals (RBM). With the COVID-19 resurgence in Quebec and South Africa, we continue to operate our assets with extensive measures in place to ensure the safety of our employees and communities. • Production of pellets and concentrate at Iron Ore Company of Canada (IOC) was 1% lower than 2019 due to unplanned maintenance at the processing facilities in the third and fourth quarters. On 3 December, we signed a Reconciliation and Collaboration Agreement with the Innu communities of Uashat mak Mani-utenam and Matimekush-Lac John, re-confirming the long-term partnership between the company and the two communities over the coming decades. • On 10 December, we disclosed a maiden Ore Reserve and updated Mineral Resource at the 100% owned Jadar lithium-borates project in western Serbia. The Ore Reserve is 16.6 million tonnes at 1.81% Li2O and 13.4% B2O3. 2 Jadar would be capable of producing approximately 55 thousand tonnes of battery grade lithium carbonate, as well as 160 thousand tonnes of boric acid (B2O3 units) and 255 thousand tonnes of sodium sulfate as by-products per annum. 3 • On 17 December, we announced the appointment of Jakob Stausholm as Chief Executive, effective 1 January 2021. Peter Cunningham has been appointed interim Chief Financial Officer, effective 1 January 2021. • On 15 January 2021, we announced that we have entered the next phase of public comment in the ongoing permitting process at the Resolution Copper Project in Arizona, led by the US Forest Service, with the release of its independently prepared Final Environmental Impact Statement (EIS). The delay in publication of the Final EIS, which was originally scheduled for July 2020 by the Obama Administration, is a result of extensive public consultation, significant interagency coordination and COVID-19 related changes to the pace of work. 1 This estimate is at a better than feasibility study level of accuracy. 2 This Ore Reserve estimate was set out in a release to the Australian Securities Exchange (ASX) dated 10 December 2020 “Rio Tinto declares maiden Ore Reserve at Jadar” (ASX release). The Competent Person responsible for the information in the ASX release that relates to Ore Reserves is Mr Allan Earl who is a Fellow of the Australasian Institute of Mining and Metallurgy (FAusIMM). Mr Earl’s assessment is supported from a metallurgical perspective by Mr Gary Davis who is a Member of the Australasian Institute of Mining and Metallurgy (MAusIMM). Rio Tinto confirms that it is not aware of any new information or data that materially affects the information included in the ASX release, that all material assumptions and technical parameters underpinning the estimates in the ASX release continue to apply and have not materially changed, and that the form and context in which the Competent Persons’ findings are presented have not been materially modified. 3 These production targets were previously reported in the ASX release on 10 December 2020. All material assumptions underpinning the production targets continue to apply and have not materially changed. 2

Cultural heritage We have commenced implementation of the recommendations from the Board review of cultural heritage management and are developing additional measures to enhance our partnerships, as we continue to focus on the longer-term process of regaining the trust of Traditional Owners. To support this, we are focused on making sure that we build a more inclusive and diverse work culture, which will require sustained effort over many years. On 9 December, we acknowledged the release of the Joint Standing Committee on Northern Australia’s interim report following the Parliamentary Inquiry into the destruction of rockshelters at Juukan Gorge. On 16 December, we set out our position on the Committee’s Recommendation 1 contained in the interim report. All documents can be found on our dedicated page on the website here. On 23 December, we issued a joint statement with the Puutu Kunti Kurrama and Pinikura (PKKP) people confirming our shared commitment to work together to rebuild our relationship following the Juukan Gorge events in May 2020. We have made strong progress in recent months: • With the PKKP, we have worked on a rehabilitation programme for the Juukan 1 and Juukan 2 rock shelters and we are assessing ways to protect the area for the future. This includes a permanent mining moratorium around the Juukan Gorge area. We have moved the artefacts previously uncovered from the rockshelters to a purpose-built facility, with the support of the PKKP. • The PKKP and Rio Tinto boards met to reaffirm our apology and commitment to rebuilding our relationship. This followed a visit to the Juukan Gorge by our Chairman and the Chair of our Sustainability Committee with PKKP elders. A summary of other key actions taken in the quarter are outlined below: • Reassessed all activities which have the potential to impact heritage sites. We will continue to review mine plans to ensure the protection of sites of exceptional cultural value and have increased monitoring of operating activities that have the potential to impact heritage sites. We have also integrated heritage management into our mining operations - our Product Groups have primary responsibility for our Communities and Social Performance (CSP) partnerships and engagement. • We have confirmed that Traditional Owners are not restricted from raising concerns about cultural heritage matters with anyone, or from applying for statutory protection of any cultural heritage sites. This forms part of our commitment to modernise our agreements with Traditional Owner groups in the Pilbara. This will take time to ensure the process involves meaningful participation of Traditional Owners. We will also engage with Traditional Owners on how best to incorporate a process of independent review to support the modernisation process. In the meantime, we continue to work with Traditional Owners under existing agreements and have increased engagement regarding current and proposed plans for mining activities. • Appointed Indigenous community leader, Wayne Bergmann, to consult with Traditional Owners on the formation of an Indigenous Advisory Group in Australia. The Advisory Group will advise the Board and senior management team and provide an alternative pathway for Traditional Owners to escalate any concerns they may have about our performance at a local level. • Strengthened the operational leadership of relationships with Traditional Owners and we are strengthening our business-wide cultural competency programme to build awareness and understanding. • Further to our commitment to invest $50 million to increase employment opportunities for Indigenous Australians in our business and enhance Indigenous leadership in our Australian operations, we have progressed plans to advance Indigenous leadership in our business with the launch of a leadership programme involving more than 200 Indigenous employees. We have also implemented a two-way mentoring relationship between Indigenous employees and senior leaders as part of a broader cultural competency programme. 3

Our markets Economic activity, particularly in Europe, continues to be disrupted in the short term due to measures to combat COVID-19. Monetary policy is expected to remain accommodative and fiscal policy is also expected to be utilised extensively, both of which should be supportive of commodity demand. • In China, the industrial sector has recovered and is now at pre-COVID levels due to the rapid deployment of stimulus. Exports continue to rise with the global economic recovery, and a policy shift to promote domestic investment and consumption is supportive of the commodity demand outlook. • Iron ore prices rose significantly in the second half of 2020 on the back of tightened market fundamentals. China’s buying remains robust despite ongoing localised impacts from COVID-19 in some regions. Demand in Japan, Korea, Taiwan and Europe is recovering, amplified by restocking. • The aluminium price has rebounded on solid downstream demand, particularly in the automotive and packaging sectors. We remain cautious on the outlook due to an expected increase in Chinese supply and high global inventories. • Copper prices remain strong. Chinese consumption is robust, mine and scrap supply have been disrupted, and investment demand is strong. We expect global fiscal stimulus, particularly in the electrification and renewables sectors, to be copper-intensive and supportive of the outlook.

Commissioning of the Industrial Research and Development Centre is now underway. • On 17 December, we announced an investment of $8.4 million to expand the recycling capacity of our aluminium operations in Saguenay-Lac-Saint-Jean, Quebec, to offer rolled product customers in North America a new, sustainable solution combining low-carbon and recycled aluminium. With an initial capacity of 22,000 metric tons of remelted aluminium per year, the new aluminium recycling system is expected to be operational at the end of 2021. • Following successful pilot plant trials to extract high purity scandium oxide from the waste streams of titanium dioxide production, on 14 January 2021 we announced an initial investment of $6 million for construction of a first module in a new commercial scale demonstration plant at our Rio Tinto Fer et Titane (RTFT) metallurgical complex in Sorel-Tracy, Quebec. Commercial supply of scandium oxide is expected in the second quarter of 2021, making RTFT the first producer of high-quality scandium oxide in North America. 4

COVID-19 We continue to manage the risk of COVID-19 as countries tighten restrictions and work to fight against a resurgence of the virus. Our absolute priority is to maintain significant levels of support and care for our employees, contractors, and host communities, particularly with the re-emerging risk for our operations and projects in Canada, the United States, South Africa and Mongolia. We are focused on well-being initiatives globally, and embrace flexible working arrangements. • At the Oyu Tolgoi operation in Mongolia, we continue to apply the strictest measures, including testing for all employees before access to site. We maintain focus on health, safety and well-being of our employees and contractors amid the restrictions on domestic and international travel, and will continue to rotate employees when safe to do so. • We are in regular contact with health authorities in Canada - both in Northern British Columbia and Quebec - with the rapid increase in cases. We are applying extensive measures to ensure the safety of our employees and communities including travel management protocols for employees and contractors along with reduced access to site. • At our Diavik operation in the Northwest Territories of Canada, since testing commenced in May, we have taken nearly 20,000 swabs at the mine site which have been analysed through our on-site laboratory, including some for nearby mines that we service. • At our Boron site in California, support has been provided to employees with ongoing rapid testing, and the implementation of reduced site hours to lessen the transmission risk and to protect our employees. • With the outbreaks in the eastern states of Australia, State border closures are being closely monitored with site access controls and travel management protocols being utilised. • We are actively managing the risks to seafarers from restrictions on crew changeovers due to COVID-19 measures in place in various countries. We continue to work with the industry, our shipowner partners and regulators to facilitate crew changes and protect crew welfare. Communities • We have committed $25 million in COVID-19 related community projects globally, with around A$20 million in Australia including A$1.25 million over five years to the Royal Flying Doctor Service to improve emergency and remotely delivered health care services across the region. • In partnership with the United Nations, we have committed $600,000 to COVID-19 relief initiatives in Mongolia including donation of laboratory equipment. We are actively engaging with local coordinators and participating in working groups to support the rollout of a vaccine. • At Richards Bay Minerals in KwaZulu-Natal, South Africa, we are committed to supporting our local communities and have donated more than R5.5 million to provide critical support to those impacted by COVID-19, including food and water supplies, as well as Personal Protective Equipment (PPE) for frontline health workers and clinics. • We are investing $10 million in a variety of grassroots projects across Canada and the United States to support local community efforts to fight COVID-19 and its social and economic impacts, along with supporting projects that maintain and create regional economic development. ◦ In Arizona, the Resolution Copper Project partnered with the United Food Bank to deliver 75,000 meals to the White Mountain Apache Tribe. It also donated 50,000 cans of water to support tribes, in partnership with Ball Corp and Can’d Aid. ◦ In the Northwest Territories, our Diavik diamond mine is partnering with the Yellowknife Women’s Society to support its COVID-19 isolation shelter with a C$150,000 contribution. We are also contributing C$60,000 to five Indigenous communities for food and other needs. Full details of initiatives taken to date can be found on our website. 5

Unadjusted Diamonds production for 2020 was 14.7 million carats, including both Diavik and Argyle operations. • We will continue to monitor and adjust production levels and product mix to meet customer requirements in line with our value over volume strategy, government imposed restrictions related to COVID-19 and any other potential COVID-19 related disruptions. • Iron ore shipments and bauxite production guidance remain subject to weather and market conditions. Iron ore guidance takes into account the risks associated with tying in approximately 90 million tonnes of replacement mine capacity at existing hubs in Robe Valley, West Angelas and Western Turner Syncline Phase 2 as well as the start-up of Gudai-Darri. • The future impact on our Pilbara iron ore operations, mine developments and heritage approach from the reform of the Aboriginal Heritage Act 1972 (WA) remains unknown. We will maintain a high level of engagement with Traditional Owners regarding current and proposed plans for mining activities and continue to work through scenarios in an iterative manner as cultural assessments and mine designs progress, with a broad range of options available given the flexibility in our Pilbara network. Investments, growth and development projects • Project teams have proactively managed COVID-19 related challenges, and overall project delivery is satisfactory. Uncertainty continues to exist around local situations, border access, movement of people and goods. • Exploration and evaluation operating expense in 2020 was $625 million, $1 million higher than 2019, with some redistribution of activities from regions with greater COVID-19 restrictions such as Europe, Central Asia and America, and ramp-up of activities in Australia following the easing of restrictions. The teams were able to keep programmes running throughout 2020 whilst maintaining strong safety standards, protecting our people and communities. Pilbara replacement projects • Gudai-Darri (formerly Koodaideri) progress continues with production ramp-up on track for early 2022. The airstrip is now complete and operational, and track work continues on the northern section of the railway. • First ore from the Robe River Joint Venture sustaining production projects (West Angelas C, D and Mesa B, C and H at Robe Valley) is still expected in 2021. All required approvals have now been received. • Construction continues to progress at Western Turner Syncline Phase 2, with the project maintaining forecast first ore in 2021. Oyu Tolgoi underground project Technical progress • Work on the project has continued to progress despite restrictions from COVID-19 controls and ongoing international travel restrictions. In November 2020, the Mongolian State Emergency Commission declared an “all out readiness state” after Mongolia recorded its first community transmission of COVID-19. All movements in and out of Ulaanbaatar and all domestic flights were halted. Critical commissioning vendors and sinking crew are in-country, however timing was impacted by the nationwide lockdown and quarantine duration. • The project has deployed a number of mitigations that include extended on-site rosters, securing commitments from critical vendors to remain on site for extended periods and layered screening of personnel. • Overall underground lateral development has now reached 53,000 equivalent metres (eqm), with development for first drawbell substantially complete. 6

• The project has now exceeded one million tonnes of material moved through shaft 2 since commissioning and scheduled annual maintenance of the shaft was successfully completed in October 2020 using remote technology. • Shaft 4 is now out of care and maintenance and the focus is on completing all construction and commissioning activities for load testing and verification, and for sinking to commence in early 2021. Shaft 3 remains on care and maintenance, with some minor construction. • On 16 December, we confirmed the definitive estimate of cost and schedule for Panel 0 with sustainable production expected to commence in October 2022 and development capital of $6.75 billion1, in line with previously announced ranges. These estimates include the known impacts of COVID-19.2 • At peak production, Oyu Tolgoi is expected to operate in the first quartile of the copper cash cost curve3 and by 2030 is expected to be the fourth largest copper mine in the world. It is expected to produce 480,000 tonnes4 of copper per year on average, from 2028 to 2036, from the open pit and underground. The underground Ore Reserve has an average copper grade of 1.52%, which is more than three times higher than the open pit Ore Reserve, and contains 0.31 grammes of gold per tonne.5 Other updates • On 4 January 2021, the Government of Mongolia advised Rio Tinto that they were dissatisfied with the results of the definitive estimate and the funding implications for the sharing of economic benefits between the shareholders of Oyu Tolgoi. The Government has also stressed the importance of achieving a comprehensive solution which addresses the social issues of importance to Mongolia, such as water usage and the corporate tax payments which have been referred to International Arbitration. We have been engaging with the Government and Turquoise Hill Resources (TRQ) to address these recent challenges within the scope of Parliament Resolution 92, and remain open to improving the Underground Development and Financing Plan (UDP) to deliver even greater benefits from Oyu Tolgoi to all stakeholders. • Rio Tinto considers that additional milestones need to be met in order to ensure that the project can commence caving operations in 2021, including: outstanding government approvals - including registering the updated Resources and Reserves submitted in February 2020 and accepting the updated feasibility study (OTFS20) completed in July 2020 in accordance with the 2009 Investment Agreement and Mongolian regulation; funding as agreed with TRQ in the MOU in September 2020; and, achieving the power milestones agreed with the Government of Mongolia in June 2020. We continue to work closely with our partners, the Government of Mongolia and TRQ in the coming months to finalise these milestones, as outlined in our 16 December release. • On 22 December, Oyu Tolgoi received a Tax Assessment claim for approximately US$228 million from the Mongolian Tax Authority (MTA), relating to an audit of taxes paid between 2016 and 2018, in addition to the $752 million paid in the same period. Oyu Tolgoi has filed an application to include these matters to the pending international arbitration related to the years 2013 to 2015, which are of a similar nature. Other key projects and exploration and evaluation • Phase one of the south wall pushback project at Kennecott remains on track, with access to higher grades expected from 2021. • The Zulti South project in South Africa remains on full suspension. • At the Kemano hydropower tunnel project in British Columbia, Canada, tunnel boring works re-started in September 2020. However, due to the escalation of COVID-19 in the province, tunnel boring operations have been temporarily suspended and the workforce has been limited to 160 people following a local order on 29 December. Care and maintenance activities are continuing on site until remobilisation plans can be safely implemented prior to resuming boring operations. • At the Resolution project in Arizona, the shaft 9 remediation and sinking project was completed in November, four months ahead of schedule and within budget. We now enter the next phase of public comment in the ongoing permitting process led by the US Forest Service (USFS), with the release of its independently prepared Final Environmental Impact Statement (EIS) as announced on 15 January. The delay in publication of the Final EIS, which was originally scheduled for July 2020 by the Obama Administration, is a result of extensive public consultation, significant interagency coordination and COVID-19 related changes to the pace of work. We are committed to ongoing stakeholder engagement in our effort to seek consent to progress the project consistent with the International Council on Mining and Metals (ICMM) Statement on Indigenous Peoples and Mining. • At the Winu project in Western Australia, drilling and fieldwork activities continue with 90 kilometres of drilling completed during 2020. We are actively engaging with the Traditional Owners through on-country heritage surveys, monitoring and agreement making, which is expected to continue into 2021, with first ore now expected in 2024, subject to regulatory approvals, Traditional Owner and other consents and COVID-19 restrictions. We further expanded our ground holdings in the Paterson region with a farm-in joint venture signed with Sipa Resources Limited adjoining Winu and the Citadel joint venture tenements. 7

• At the Simandou iron ore project in Guinea, we expect to complete the first phase of the technical optimisation work on the infrastructure components in the first half of 2021. Activity at the mine area is starting including roadworks. We are progressing the implementation of the project’s 2012 Social and Environmental Impact Assessment (SEIA). • The feasibility study at the Jadar lithium-borate project in Serbia continues and is expected to complete by the end of 2021. If the investment is approved, construction would take approximately four years. The declaration of resources and reserves in December was an important milestone as the project progresses towards the award of an exploitation license, the precursor to a construction licence. 1 This estimate is at a better than feasibility study level of accuracy. 2 The definitive estimate assumes restrictions in 2021 that are no more stringent than those experienced in September 2020. Mongolia implemented further restrictions at the end of 2020 in response to a re-emergence of COVID-19. Should COVID-19 constraints be maintained at December 2020 levels, escalate further in 2021 leading to tougher restrictions, or continue beyond 2021, additional costs and schedule impacts will arise. 3 WoodMackenzie copper equivalent cash cost curve (Q3 2020). 4 This production target (stated as recovered metal) for the Oyu Tolgoi underground and open pit mines was previously reported in a release to the market on 16 December 2020 (Market release).

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 Pilbara operations produced 333.4 million tonnes (Rio Tinto share 275.5 million tonnes), 2% higher than 2019. Fourth quarter production of 86.0 million tonnes (Rio Tinto share 71.0 million tonnes) was 3% higher than the same period of 2019. Our mines also achieved record total material moved for the year, 7% higher than the previous record from 2019, highlighting the improvements to mine and asset health since 2019. A solid operational performance, considering weather disruptions and strict measures implemented in the second quarter to manage COVID-19. 2020 shipments of 330.6 million tonnes (Rio Tinto share 273.1 million tonnes) were 1% higher than 2019. Shipments were impacted by Cyclone Damien in the first quarter and by the impacts of COVID-19, which also resulted in the deferral of maintenance at the port in the the third quarter. Fourth quarter shipments of 88.9 million tonnes (Rio Tinto share 73.6 million tonnes) were 2% higher than the fourth quarter of 2019. Whilst the port and rail currently hold the most capacity, the timing impacts of maintenance and grade blending resulted in the gap between final 2020 shipping and production figures. Achieved realised pricing in 2020 was $91.0 per wet metric tonne on an FOB basis (equivalent to $98.9 per dry metric tonne, at 8% moisture assumption). This compares to the average price for the Platts 62% index of $101.6 per dry metric tonne. In 2019, average pricing was $79.0 per wet metric tonne ($85.9 dry metric tonne). Lower market premiums for lump, which recovered in the fourth quarter, and the rising price environment throughout 2020 impacted our average achieved pricing compared with Platts due to the structure of our contracts, with approximately 13% of shipments in 2020 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 or on the spot market. Approximately 30% of 2020 sales were made on a free on board (FOB) basis, with the remainder sold including freight. 9

China Portside Trading We continue to ramp up our port sales in China, with 5.5 million tonnes of sales in 2020 including 1.8 million tonnes in the fourth quarter. Our portside operation handles product from our operations in the Pilbara and in Canada as well as third party product, and provides blending and screening capabilities. 10

ALUMINIUM Rio Tinto share of production (‘000 tonnes) Q4 2020 vs Q4 2019 vs Q3 2020 Full Year 2020 vs Full Year 2019 Bauxite 13,299 -12 % -8 % 56,131 +2 % Bauxite third party shipments 9,104 -17 % -10 % 39,357 -1 % Alumina 2,085 +3 % +7 % 8,039 +4 % Aluminium 815 +4 % +2 % 3,180 0 % Bauxite Bauxite production of 56.1 million tonnes was 2% higher than 2019 supported by the ramp-up of the expansion at the CBG mine in Guinea, and steady performance at the Pacific mines, including additional volumes from the start-up of the Amrun mine in 2019. Fourth quarter bauxite production was 12% lower than the very strong quarter in 2019, reflecting phasing across the year to align with customer needs and a train failure at the Andoom mine at Weipa. This was partly offset by increased production from the expansion at the non-managed CBG mine in Guinea. We shipped 39.4 million tonnes of bauxite to third parties in 2020, 1% lower than 2019. Shipments were prioritised throughout the year to align with customer needs, with a higher proportion of internal shipments to the Pacific refineries in the fourth quarter. Alumina Alumina production of 8.0 million tonnes was 4% higher than 2019 and the fourth quarter was 3% higher than the same period of 2019, as a result of strong production at both our Pacific refineries. Aluminium Aluminium production of 3.2 million tonnes was in line with 2019, with lower volumes from the curtailment of Line 4 at the Tiwai Point smelter in New Zealand and from the Kitimat smelter pot relining campaign, offset by the ramp-up of the Becancour smelter in Quebec, following its restart after a lockout at the end of 2019. Production of 0.8 million tonnes in the fourth quarter was 4% higher than the fourth quarter of 2019 underpinned by the Becancour smelter operating at full capacity and the Kitimat smelter progressing well on its pot relining campaign. Average realised aluminium prices including both product and market premiums for value-added products (VAP) were down by 9% to $1,946 per tonne in 2020 (2019: $2,132 per tonne). The LME price decreased by 5% to $1,702 per tonne (2019: $1,791), whilst the mid-west premium duty paid dropped by 2% to $313 per tonne in 2020 due to the impact of COVID-19 (2019: $320 per tonne). Our VAP sales dropped to 43% of primary metal sold in 2020 in line with the market (2019: 51%). Product premiums for VAP sales declined by 9% averaging, $213 per tonne of VAP sold (2019: $234 per tonne). Market demand for VAP rebounded in the fourth quarter of 2020, returning to normal levels. A 10% tariff on Canadian P1020 aluminium imports into the United States was paid between 6 August and 1 September 2020 under Section 232. In January 2021, Rio Tinto reached an agreement on a new electricity supply agreement with Meridian Energy that allows New Zealand Aluminium Smelter (NZAS) to continue operating the Tiwai Point smelter until December, 2024. The extension of operations provides certainty to employees, the local community and customers while providing more time for all stakeholders to plan for the future. Work is ongoing on the strategic review of the ISAL smelter in Iceland, announced in February 2020. In July 2020, we submitted a complaint to the Icelandic Competition Authority (ICA), alleging abuse of market dominance by energy supplier Landsvirkjun. Discussions with Landsvirkjun, to improve the competitiveness of the asset, are ongoing. 11

COPPER AND DIAMONDS Rio Tinto share of production (‘000 tonnes) Q4 2020 vs Q4 2019 vs Q3 2020 Full Year 2020 vs Full Year 2019 Mined copper Kennecott 33.8 -4 % -2 % 140.0 -25 % Escondida 84.8 -8 % +2 % 337.8 -1 % Oyu Tolgoi 14.0 +27 % +15 % 50.2 +2 % Refined copper Kennecott 40.9 -21 % +292 % 84.8 -54 % Escondida 15.2 -26 % +6 % 70.2 -7 % Rio Tinto share of production (‘000 carats) Q4 2020 vs Q4 2019 vs Q3 2020 Full Year 2020 vs Full Year 2019 Argyle 1,893 -44 % -41 % 10,945 -16 % Diavik 910 +8 % -9 % 3,731 -7 % Kennecott Mined copper production was 25% lower than 2019, due to a 28% reduction in grade. This was as a result of lower grades at the end of the east wall mining and sequencing to optimise molybdenum ore production during the extended smelter shutdown in the second and third quarters. Development in the pit progressed despite the effects from the earthquake in March and COVID-19 disruptions. As a result, grades are expected to gradually increase from 2021, with the transition from east to south wall mining. Refined copper production was 54% lower than 2019 due to the flash converting furnace rebuild required following the earthquake and delays in restarting the smelter following planned major maintenance in mid-2020. The smelter was safely restarted and became fully operational during October. Approximately 60,000 dry metric tonnes of copper concentrate sales were realised in the fourth quarter to manage inventory as a result of the delayed smelter re-start, taking advantage of the strengthened market. Molybdenum concentrate production was 82% higher than 2019, due to significantly higher head grades in the lower pit of the east wall mine sequence, and productivity improvements. Escondida Mined copper production was 1% lower than 2019, mainly due to 15% lower material stacked into the leaching pads as a result of preventive measures in response to COVID-19, which was offset by 5% higher concentrator throughput in 2020. Refined copper was also impacted by lower material stacked into the leach pads. Oyu Tolgoi Mined copper production from the open pit was 2% higher than 2019, reflective of the anticipated move to higher grade areas of the open pit, primarily due to accelerated mine development and production phasing. In the fourth quarter, pit phasing delivered higher gold production (+139%) compared to the prior quarter. Access to higher copper and gold grades is expected to continue throughout 2021. We maintained shipments across the Chinese border despite COVID-19 measures in Mongolia. We continue to work closely with authorities to manage the risk of supply chain disruptions due to COVID-19. 12

Provisional pricing At 31 December 2020, the Group had approximately 260 million pounds of copper sales that were provisionally priced at 336 cents per pound. The final price of these sales will be determined during the first half of 2021. This compares with 220 million pounds of open shipments at 31 December 2019, provisionally priced at 271 cents per pound. Provisional pricing adjustments positively impacted revenues in 2020 by $182 million (2019 positive impact of $6 million). Diamonds On 3 November, we announced the final day of mining at Argyle after 37 years of operations. The closure process is expected to take five years to decommission and dismantle the mine and undertake rehabilitation, followed by a further period of monitoring. The penultimate Argyle Pink Diamonds tender continued its trajectory of double digit price growth and a record number of participants with successful bidders from eight countries. At Diavik, carats recovered in 2020 were 7% lower than 2019, with a 10% grade reduction partially offset by an increase in ore tonnes processed. 13

Fourth quarter production was 7% higher than corresponding period in 2019. On 3 December, we signed a Reconciliation and Collaboration Agreement with the Innu communities of Uashat mak Mani-utenam and Matimekush-Lac John. This long term partnership will provide the foundation for a new mutually beneficial relationship based on dialogue, openness and trust between the company and the two communities over the coming decades. We have continued the optimisation of IOC product mix to match market demand, returning to higher pellet production with all six lines in operation, following signs of recovery in demand from Europe. Borates Borates production was 8% lower than 2019 due to a period of lower demand related to COVID-19 uncertainty resulting in an adjustment to refinery operating rates. The extension of a planned shutdown impacted fourth quarter production. Iron and Titanium Titanium dioxide production was 7% lower than 2019, as we focused on our value over volume strategy to match market. We experienced operational challenges at Richards Bay Minerals (RBM) due to a submerged dredge in the fourth quarter, and as a result, production was 5% lower than the corresponding quarter in 2019. Mitigations are in place to ensure customer supply throughout 2021. Uranium Our share of production was 9% higher than 2019, primarily due to our change in shareholding following completion of ERA’s entitlement offer in February 2020 (our shareholding of ERA increased from 68.39 to 86.33 per cent). ERA’s Ranger operation continued to process existing stockpiles uninterrupted during the fourth quarter, with production ceasing as of 8 January 2021, as required. 14

EXPLORATION AND EVALUATION Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account for 2020 was $625 million, compared with $624 million in 2019. Approximately 42% of this expenditure was incurred by central exploration, 40% by Copper & Diamonds, 9% by Energy & Minerals and 9% by Iron Ore. There were no significant divestments of central exploration properties in 2020. Exploration highlights Rio Tinto has a strong portfolio of projects with activity in 16 countries across eight commodities in early exploration and studies stages. All projects have followed government COVID-19 requirements and guidelines while focusing on protecting health and well-being of local and Indigenous communities. The bulk of the exploration expenditure in the fourth quarter focused on copper in Australia, Kazakhstan, United States and Zambia, and diamonds projects in Canada. Mine-lease exploration continued at Rio Tinto managed businesses including Pilbara Iron in Australia, and Diavik in Canada. Our exploration team have won the 2020 Association of Mining and Exploration Companies Prospector of the Year Award in Australia, for our copper-gold discovery at Winu in Western Australia, recognising the most outstanding mineral deposit discovery and the team who made the discovery. At Falcon, bulk sample processing and final diamond recovery have been completed for ten trenches drilled in 2019, and reported in December 2020. Inspection, valuation and interpretation is ongoing.
