Notice to ASX/LSE Page 1 of 2 Statement on amended assessments 2 March 2021 The Australian Taxation Office (ATO) has issued Rio Tinto Limited with amended assessments of A$359.4m (US$279.8m) primary tax and A$47.1m (US$36.7m) of interest. This is in addition to the more than A$8.4bn (US$6.4bn) of Australian income tax paid during the relevant period. The assessments relate to the denial of interest deductions on an isolated borrowing used to pay an intragroup dividend in 2015. This borrowing was repaid in 2018. Borrowing to fund the payment of a dividend is a normal commercial practice. Rio Tinto is confident of its position and will dispute the assessments. In accordance with the usual practice Rio Tinto will pay 50% of the primary tax up-front as part of the objections process. EXHIBIT 99.2

Rio Tinto to build new tellurium plant at Kennecott mine

8 March 2021

SALT LAKE CITY, United States – Rio Tinto will begin construction on a new plant that will recover tellurium, a critical mineral used in solar panels, from copper refining at its Kennecott mine near Salt Lake City, Utah.

Rio Tinto is investing $2.9 million to set up the plant, which will recover tellurium as a byproduct of copper smelting, extracting a valuable mineral from waste streams. The plant will have a capacity to produce approximately 20 tonnes of tellurium per year.

Rio Tinto expects to begin production of tellurium in the fourth quarter of 2021, creating a new North American supply chain for this critical mineral.

Tellurium is an essential component of cadmium telluride, a semiconductor used to manufacture thin film photovoltaic (PV) solar panels. Thin films made of this compound can efficiently convert sunlight into electricity. Tellurium can also be used as an additive to steel and copper to improve machinability, making these metals easier to cut. It can also be added to lead to increase resistance to sulfuric acid, vibration and fatigue.

Rio Tinto Kennecott managing director Gaby Poirier said: “The minerals and metals we produce are essential to accelerate the transition to renewable energy. Adding tellurium to our product portfolio provides customers in North America with a secure and reliable source of tellurium produced at the highest environmental and labour standards with renewable energy. Rio Tinto is committed to using innovation to reduce waste in our production process and extract as much value as possible from the material that we mine and process.”

Utah Governor Spencer Cox said: “With abundant natural resources, Utah is ideally positioned to help supply the critical minerals essential to maintain American manufacturing competitiveness. Rio Tinto’s smelter at Kennecott is one of only two that is capable of producing copper and other critical minerals. The new tellurium plant is another valuable contribution to critical mineral independence and energy security in the U.S.”

Along with producing almost 20 per cent of U.S. copper, Kennecott’s smelting process also recovers gold, silver, lead carbonate, platinum, palladium and selenium, while molybdenum is recovered from the Copperton concentrator. In total, nine products are currently recovered from the ore extracted at Kennecott.

Rio Tinto is a partner with the U.S. Department of Energy’s Critical Materials Institute (CMI) and works closely with CMI experts to discover further ways to economically recover critical mineral byproducts such as rhenium, tellurium and lithium. The company is also investing in new facilities to extract battery grade lithium from waste rock at its Boron, California mine site and high quality scandium oxide from waste streams at its metallurgical complex in Sorel-Tracy, Quebec.

Notes to editors

As part of its commitment to a more sustainable future, Kennecott decided in 2019 to permanently shut its coal power plant and purchase renewable energy certificates, reducing the annual carbon footprint associated with its operation by as much as 65 per cent. In 2020, Kennecott also became the first producer to be awarded the Copper Mark, the copper industry’s new independently assessed responsible production programme, demonstrating it meets over 30 criteria for responsible environmental, social and governance practices. Recovering tellurium, an essential material for renewable energy production, reinforces Kennecott’s position as a supplier of choice of low carbon and responsible products to its customers and end-users.

Rio Tinto invests a further $92 million in Isle-Maligne power plant

9 March 2021

ALMA, Canada – Rio Tinto is investing a further C$92 million in maintenance work and upgrades to improve the reliability and efficiency of its Isle-Maligne hydroelectric station, which is essential to the production of hydroelectricity for the manufacture of low-carbon aluminum in Saguenay–Lac-Saint-Jean, Quebec.

Located in Alma, the plant was commissioned 95 years ago and is the oldest in Rio Tinto's hydroelectric network.

The work will work begin this summer and take place over two years, with one turbine-alternator group being replaced and major maintenance work undertaken on another. The plant will be upgraded with state-of-the-art instrumentation and information management technologies to deliver improved operational efficiencies.

Sébastien Ross, Managing Director of Rio Tinto's Quebec operations, said: "This work at the Isle-Maligne power plant represents a major investment by Rio Tinto in the region that will enable us to continue our hydroelectric operations and maintain our low-carbon footprint aluminium production in Quebec.”

The project is expected to generate C$75 million in economic activity in Quebec and more than a hundred workers will be involved at the peak of the work.

GE Renewable Energy will deliver engineering, fabrication and installation of the replacement turbine-alternator group.

The investment adds to a C$160 million maintenance project announced in October 2020 to replace valves in the Isle-Maligne station.

Note to editors

Rio Tinto produces some of the world’s highest quality and lowest carbon aluminium at its operations in Quebec, which are powered with 100% clean, renewable hydroelectricity.

Rio Tinto is Canada's largest private producer of hydroelectricity. Its seven hydroelectric facilities, located in Quebec and British Columbia, provide a competitive advantage, allowing the company's modern aluminum smelters to position themselves favourably in the industry.

Thanks to its hydroelectric production, Rio Tinto is an industry leader in responsile aluminium production. In 2016, the company launched the industry's first certified low-carbon aluminium, RenewAlTM, with a footprint of 4t CO2/t Al or less. It has helped to pioneer responsible production standards for the global industry as a founding member of the Aluminium Stewardship Initiative (ASI), becoming the first producer to offer ASI Aluminium in 2018.

Notice to ASX Page 1 of 3 Resolutions requisitioned by shareholders 9 March 2021 In accordance with ASX Listing Rule 3.17A.1, Rio Tinto advises that it has received resolutions from two groups of shareholders under section 249N of the Corporations Act 2001 for consideration at Rio Tinto Limited’s Annual General Meeting to be held on 6 May 2021. A group of shareholders representing 0.02% of the shares on issue in Rio Tinto Limited have proposed the following resolutions: 1. An amendment to the company’s constitution to permit the company’s members in general meeting to pass an advisory resolution expressing an opinion or requesting information about the way in which a power of the company vested in the directors has been or should be exercised; and 2. A request that the company disclose, in subsequent annual reporting, short, medium and long-term targets for its scope 1 and 2 greenhouse gas emissions and performance against those targets. Another group of shareholders representing 0.01% of the shares on issue in Rio Tinto Limited have proposed the following resolutions: 1. An amendment to the company’s constitution to permit the company’s members in general meeting to pass an advisory resolution expressing an opinion, asking for information, or making a request about the way in which a power of the company vested in the directors has been or should be exercised; and 2. A request that the company enhance its annual review of industry associations to ensure that the review identifies areas of inconsistency with the Paris Agreement, and a recommendation that the company suspend membership, for a period deemed suitable by the Board, where an industry association’s record of advocacy is, on balance, inconsistent with the Paris Agreement’s goals. Rio Tinto welcomes dialogue on these important matters, and recognises that its portfolio of high-quality iron ore, copper, aluminium and minerals has an essential role in enabling the low-carbon transition. We divested the last of our coal businesses in 2018 and no longer extract fossil fuels. Our climate scenario analysis shows that our portfolio is resilient to climate change risks both in absolute as well as relative terms, compared to other companies in our sector. Overall, our portfolio is expected to perform more strongly in scenarios with proactive climate action and a faster low carbon transition. In 2021, the Remuneration Committee approved revisions to how we include climate change in the short-term incentive plans of our senior executives. Safety, environment, social and governance matters including climate change are now assigned an explicit performance weighting of 35%, of which 20% relates to safety. The Board intends to put the company’s annual TCFD-aligned reporting to an advisory vote at our 2022 Annual General Meetings. Our 2030 targets are aligned with the goals of the Paris Agreement and the Intergovernmental Panel on Climate Change pathway to 1.5°C which requires a 45% reduction in global emissions by 2030 relative to 2010 levels. Most of our assets already sit in the low end of their respective carbon intensity curves. In 2020 we focused on executing the climate strategy and working towards our 2030 targets. Since 2018, we have reduced Scope 1 and 2 emissions by 1.1Mt CO2e, or 3%, which is on track with our 2030 emissions target. We started the transition to renewable energy in the Pilbara by approving the 34MW solar plant at Gudai-Darri. Our approved spend on climate-related projects in 2020 was over $140 million of the total $1 billion committed over the period 2020 to 2024. We also updated our methodology for calculating Scope 3 emissions and set new Scope 3 emissions reduction goals to guide our partnership approach across our value chains. Industry associations play an important role in policy development, sharing best practice and developing standards. They also allow us to better understand a range of external views and contribute our perspectives and experiences in support of a co-ordinated approach which benefits business, the economy and society. Recognising that industry associations’ views will not always be the same as ours, we monitor the advocacy of industry associations and periodically review our memberships. Where our membership is significant, we will EXHIBIT 99.6

Page 2 of 3 work in partnership with industry associations to ensure that their policy positions and advocacy are consistent with our own public position and the Paris Agreement. We consider climate change the challenge of our generation, so it is a key topic of discussion during our regular Board and senior management engagements with investors and civil society organisations. The best solutions will come from collaboration. An addendum to Rio Tinto Limited’s notice of meeting setting out the shareholder requisitioned resolutions received by the company under section 249N of the Australian Corporations Act 2001, and the board’s response and voting recommendation with respect to those resolutions, will be issued during the week commencing 15 March 2021.

Under the agreement, Rio Tinto will deliver alloy billets made of responsibly produced, low carbon aluminium from its hydro-powered Canadian smelters and high purity scandium oxide from its Rio Tinto Fer et Titane (RTFT) metallurgical complex in Sorel-Tracy, Quebec. The billets will be processed by Amaero into powder for 3D printing and offered to the market for high temperature applications.

The scandium oxide will be supplied from a new plant Rio Tinto is building in Sorel-Tracy, Quebec, bringing the first North American supply source to the world. The plant will use an innovative recovery process developed by Rio Tinto scientists to extract high purity scandium oxide from the waste streams of titanium dioxide production, without the need for any additional mining.

The companies will also collaborate to develop the supply chain for Amaero’s high performance, High Operating Temperature Aluminium Alloy, “Amaero HOT Al”, and commercialise this lightweight material for applications in the aerospace, defence and other industries.

Rio Tinto Aluminium vice president Sales and Marketing Tolga Egrilmezer said: “As a global leader in aluminium and the first producer of high-quality scandium oxide in North America, Rio Tinto is uniquely positioned to provide a secure source of aluminium-scandium alloy to the market. Aluminium-scandium alloy is the material of choice where a lightweight, high-strength material with thermal resistance and good welding properties is needed, such as for defence and aerospace applications. This first sale demonstrates our ability to develop products that meet our customers’ needs, drawing on our technical expertise and world class assets.”

Amaero chief executive officer Barrie Finnin said: “We are very pleased to enter this Agreement with Rio Tinto to purchase the first commercial batch of aluminium scandium alloy from a North American source. This is an important step in the commercialisation of this high performance alloy that will be used in our breakthrough 3D metal printing technology. We look forward to working with Rio Tinto to progress the production of the alloy so we can commence the qualification process with key customers in the aerospace sector and other industries.”

Rio Tinto outlines path to stronger Cultural Heritage management

23 March 2021

Rio Tinto will today detail how it is working in partnership with Traditional Owners, host communities and independent groups to strengthen and improve its approach to cultural heritage and community relations.

In virtual seminars, which will include presentations from Board and Executive Committee members as well as experts in the field, Rio Tinto will outline actions it has introduced to strengthen its performance and governance of cultural heritage following the destruction of the rockshelters at Juukan Gorge in May 2020 and outline the steps it will take to further improve its performance.

One key step is today’s confirmation that an Indigenous Advisory Group (IAG) will be established to ensure Rio Tinto has a better understanding of Indigenous culture and issues in Australia, including at Board level. It follows broad consultation with Traditional Owners and Indigenous leaders with the aim to introduce more diversity and breadth of views, including external perspective, in decision-making.

Rio Tinto has also commenced work to review and re-define what is best practice for cultural heritage management in the mining industry. This work will be done in consultation with the IAG and other independent parties and will enable Rio Tinto to identify gaps in current protocols and provide a clear pathway to re-establish trust over time and regain Rio Tinto’s previous standing in this area.

Rio Tinto Chief Executive Jakob Stausholm said: “We have reflected a great deal as a company and leadership team over recent months – listening, learning and responding by taking actions to better manage Traditional Owner partnerships and cultural heritage aspects of our business.

“One thing is clear – building meaningful and trusting relationships is fundamental. And that starts with Traditional Owners. We must focus on real engagement with our communities, understanding their felt experience and never forgetting that, ultimately, we are guests on their land. And, as guests, we must respect our hosts and work with them to understand their priorities and concerns and minimise our impacts.

“We also must remember that our stay is temporary. We need to ensure we leave a positive legacy. This is essential to our business. We are committed to doing the right thing and working with our hosts to earn the right to be a trusted partner once more.”

Following the events at Juukan Gorge, Rio Tinto reviewed its internal processes and also consulted widely with Traditional Owners, host communities, governments and other stakeholders. As a result, the company has significantly strengthened internal practices, policies and governance.

As part of Rio Tinto’s efforts to increase transparency in its approach to cultural heritage, the company has also committed to additional disclosures on the progress of heritage measures being undertaken. Rio Tinto is also engaging with a number of global investors and investor groups1, to jointly identify additional disclosures on:

1.Progress against Rio Tinto’s own commitments and internal work-streams, (including Trusted Partnership Plan), external obligations and recommendations.

2.How Traditional Owners’ views are being sought and considered in shaping these commitments and Traditional Owners’ perspectives on how successfully these commitments are being met.

3.Enhanced governance arrangements in place to oversee the company’s progress against these actions.

4.How the company is working to advocate for enhanced sector-wide cultural heritage management and how this is consistent with Rio Tinto’s internal standards.

Rio Tinto intends to commence with interim reporting in the third quarter of 2021 and thereafter with predominantly annual reporting, coupled with periodic disclosure as appropriate. Further consultation with a broad range of investors and other stakeholders will continue to assist in developing these disclosures over time.

The two Communities & Social Performance: Cultural Heritage seminars will take place on 23 March, 9.00am-10.30am (AEDT) and 10.30am-12.00 pm (GMT). The presentations will be via webcast followed by a question and answer session. Presenting at the seminars will be:

Rio Tinto selects Heliogen’s breakthrough solar technology to provide carbon-free energy to Boron mine

24 March 2021

LONDON and PASADENA, Calif. – International mining and metals company Rio Tinto and renewable energy technology company Heliogen today announced an agreement to explore the deployment of Heliogen’s breakthrough solar technology at Rio Tinto’s borates mine in Boron, California.

Under a Memorandum of Understanding, Heliogen will deploy its proprietary, artificial intelligence (AI)-powered technology at the Boron operation, where it will use heat from the sun to generate and store carbon-free energy to power the mine’s industrial processes. The two companies will begin detailed planning and securing government permits for the project, with the aim of starting operations from 2022. The companies will also use the Boron installation to begin exploring the potential for deployments of Heliogen’s technology at Rio Tinto’s other operations around the world to supply process heat, which accounted for 14 per cent of Scope 1 & 2 emissions from the Group’s managed operations in 2020.

Heliogen’s high-temperature solar technology is designed to cost-effectively replace fossil fuels with sunlight for a range of industrial processes, including those used in mining. At Rio Tinto’s Boron mine, the company’s proprietary technology will use AI to control a network of mirrors that concentrate sunlight to capture energy used to make steam. Heliogen’s system will also store the captured energy in the form of heat, allowing it to power nighttime operations and providing the same uninterrupted energy stream offered by legacy fuels.

The Boron operation mines and refines borates into products ranging from fertilizers to construction materials and is producing lithium carbonate from a demonstration plant. The site currently generates steam using a natural gas cogeneration plant and natural gas fired boilers. Heliogen’s installation will supplement these energy sources by generating up to 35,000 pounds per hour of steam to power operations, with the potential to reduce carbon emissions at the Boron site by around 7 per cent – equivalent to taking more than 5,000 cars off the road. Rio Tinto will also be assessing the potential for larger scale use of the Heliogen technology at Boron to reduce the site’s carbon footprint by up to 24 per cent.

Heliogen’s mission of slashing global carbon emissions by replacing fossil fuels with sunlight, as well as its focus on industrial sectors, made them an ideal partner for Rio Tinto, which is committed to decarbonizing its global operations.

Rio Tinto Chief Executive Jakob Stausholm said: “This partnership with Heliogen has the potential to significantly reduce our emissions at Boron by using this groundbreaking solar technology, and we look forward to exploring opportunities across our global portfolio.

“Addressing climate change effectively will require businesses, governments and society to work together through partnerships like this one, to explore innovative new solutions throughout the entire value chain. Our work with Heliogen is part of Rio Tinto’s commitment to spend approximately $1 billion on emissions reduction initiatives through to 2025 and our commitment to work with world-leading technology providers to achieve this goal.”

Page 1 of 3

Heliogen CEO and Founder Bill Gross said: “Since its founding, Heliogen has been laser-focused on decarbonizing industrial sectors, including mining. As a result, this agreement with Rio Tinto is incredibly gratifying. We’re pleased to find a partner committed to cutting its contributions to climate change. We’re also pleased that Rio Tinto is exploring our technology to play an important role in helping reach its sustainability goals while dramatically reducing its energy costs. More broadly, we’re excited to take this important step as we pursue Heliogen’s goal of avoiding more than 1 gigaton of CO2 emissions – 5 per cent of the world’s annual total – from the global economy by turning sunlight into an industrial energy source.”

About Rio Tinto

Rio Tinto produces high-quality iron ore, copper, aluminium and minerals that have an essential role in enabling the low-carbon transition. We divested the last of our coal businesses in 2018 and no longer extract fossil fuels.

We have publicly acknowledged the reality of climate change for over two decades and have reduced our emissions footprint by over 30 per cent in the decade to 2020.

We have set 2030 targets to reduce our absolute emissions by 15% and our emissions intensity by 30% relative to our 2018 baseline. These targets are consistent with a 45% reduction in absolute emissions, relative to 2010 levels, and the Intergovernmental Panel on Climate Change (IPCC) pathways to 1.5°C. They are supported by our commitment to spend approximately $1 billion on emissions reduction initiatives over the first five years of the ten-year target period. In 2020 we set new Scope 3 emissions reduction goals to guide our partnership approach across our value chain.

About Heliogen

Heliogen is a renewable energy technology company focused on eliminating the need for fossil fuels in all sectors of the economy and empowering a sustainable future. The company’s proprietary technology cost-effectively delivers near 24/7 carbon-free energy in the form of heat, electricity, and green hydrogen fuel at scale for the first time in history. Heliogen was created at Idealab, the leading technology incubator founded by Bill Gross in 1996.

In November 2020, TIME included Heliogen’s HelioHeat technology on its Best Inventions of 2020 list. In April 2020, Fast Company selected Heliogen as a recipient of a 2020 World Changing Ideas Award for its technology. The company won the Energy category.
