Rio Tinto starts BlueSmelting demonstration plant to validate decarbonisation technology

03 April 2023

SOREL-TRACY, Canada - Rio Tinto Iron and Titanium (RTIT) has started its BlueSmeltingTM demonstration plant at its metallurgical complex in Sorel-Tracy as part of the process to validate the BlueSmeltingTM technology, which aims to decarbonise RTIT's Quebec Operations.

The BlueSmeltingTM project involves an ilmenite reduction technology that could generate 95% less greenhouse gas emissions than the current reduction process, enabling the production of titanium dioxide, steel and metal powders with a significantly lower carbon footprint. This innovative technology was developed by scientists at Rio Tinto's Critical Minerals and Technology Centre in Sorel-Tracy.

The project is part of a partnership between Rio Tinto and the Government of Canada to invest up to C$737 million (US$537 million) over the next eight years to decarbonise the Sorel-Tracy facility and to position the business as a centre of excellence in critical minerals processing.

RTIT Vice President Technology and Program Lead for Minerals Processing Decarbonisation Didier Arseguel said: “We are extremely proud to start the BlueSmeltingTM plant, which is a key component of Rio Tinto's decarbonisation strategy in Quebec. Thanks to the ongoing commitment of all the teams involved in this groundbreaking technology project, we have gone safely from concept to start-up in just 14 months.”

The project aims to reduce the consumption of coal in the processing of ilmenite ore. The demonstration plant can process up to 40,000 tonnes of ilmenite per year, making it the largest in the world based on this type of technology. 27 new jobs have been created to date to operate the new facility.

Notes to editors

The BlueSmeltingTM plant is part of Rio Tinto's decarbonisation strategy, which aims to reduce the company’s emissions by 50% by 2030 and achieve net zero emissions by 2050. If fully implemented, the BlueSmeltingTM project has the potential to deliver a reduction of up to 70% in RTIT Quebec Operations’s overall greenhouse gas emissions, a decrease of approximately 670,000 tCO2e based on 2021 emissions or the equivalent to removing 145,000 cars from the road.

Rio Tinto releases details of $10.8 billion of taxes and royalties paid in 2022

03 April 2023

MELBOURNE, Australia--(BUSINESS WIRE)-- Rio Tinto has published its 2022 Taxes and Royalties Paid Report, detailing $10.8 billion of global taxes and royalties paid during the year.

This compares to $13.3 billion in 2021, during very strong commodity prices, and is the third-highest annual global taxes and royalties paid by Rio Tinto since it published its first annual Taxes Paid report, for 2010.

In Australia, which is home to almost half of the company’s assets, $8.5 billion (A$12.3 billion) was paid in taxes and royalties in 2022, down from $11.1 billion (A$14.8 billion) in 2021. Rio Tinto also made significant tax and royalty payments in Canada ($718 million), Chile ($678 million), Mongolia ($294 million) and the United States ($135 million).

Rio Tinto Chief Financial Officer Peter Cunningham said “At Rio Tinto, we are finding better ways to provide the materials the world needs, and it is important that we do this responsibly and transparently, while contributing to the host countries and communities where we live and work.

“Taxes and royalties play a critical role in the economic and social development of the regions and communities we operate in. As temporary custodians of the land where we operate, we have a responsibility to extract value from the minerals and materials we produce in the safest and most sustainable way. This includes providing economic opportunities; safeguarding and promoting health, wellbeing, and human rights; combatting climate change; and being the best possible stewards of the natural resources entrusted to us.”

In the past ten years, Rio Tinto has paid $74.9 billion in taxes and royalties globally, of which more than 78% was paid in Australia.

Notice to ASX/LSE 4 April 2023 Rio Tinto to support ERA’s entitlement offer to raise funds for Ranger rehabilitation Rio Tinto will support Energy Resources of Australia Ltd’s (ERA) recently disclosed plans for an Interim Entitlement Offer (IEO), which seeks to raise up to A$369 million to address funding requirements for the Ranger Rehabilitation Project in Australia’s Northern Territory to the end of Q2 2024. Rio Tinto, which owns 86.3% of ERA’s shares, has pre-committed to subscribe for its full entitlements under the terms of the IEO, at a cost of A$319 million. Rio Tinto Chief Executive, Australia, Kellie Parker said “We are committed to ensuring the critical rehabilitation of Ranger is completed to a standard that will establish an environment similar to the adjacent Kakadu National Park.” Rio Tinto notes that ERA has, in the IEO offer material, recognised the Mirarr People’s opposition to further uranium mining on their land. This was a relevant factor in Rio Tinto’s recent decision to no longer report the Jabiluka deposit as a mineral resource. Rio Tinto also recognises that the Mirarr People’s continued involvement in and support of the Ranger Rehabilitation Project is critical for its timely completion and success. As announced by ERA today, funds from the IEO are not expected to generate any financial return and will be dedicated strictly to the Ranger Rehabilitation Project and repayment of the credit facility. Funds raised from this IEO will be partly used to repay a A$100 million credit facility provided by Rio Tinto to assist ERA with its management of immediate liquidity issues. Exhibit 99.4

Rio Tinto engages with investor and civil society organisations on enhanced advocacy approach

05 April 2023

MELBOURNE, Australia--(BUSINESS WIRE)-- In the lead up to its Annual General Meetings, Rio Tinto is engaging with investor and civil society organisations on an enhanced approach to advocacy to support the decarbonisation of its operations, in line with the goals of the Paris Agreement.

The discussions have highlighted the need for greater transparency and conversation on the critical role of government policy signals in decarbonisation by creating the right framework for change in hard to abate industrial value chains, coupled with real business action and societal shifts.

Rio Tinto put the low carbon transition at the heart of its business strategy in 2021, setting a clear pathway to provide the materials the world needs for the energy transition and ambitious targets to decarbonise its business.

Rio Tinto’s enhanced climate advocacy approach will include publishing briefing papers on specific assets and emission sources this year, detailing how the right policy-settings can support its Scope 1 and 2 emissions targets, which are aligned with the goal of limiting global warming to 1.5°C, as well as decarbonising the wider value chain. Rio Tinto will engage with the Australasian Centre for Corporate Responsibility during the development of these briefing papers, particularly on the detail included on the identified policy-settings.

Notes to editors

Summary of Rio Tinto’s positions on climate change policy:

•We agree with the mainstream climate science published by the Intergovernmental Panel on Climate Change. We support the Glasgow Climate Pact, in which governments resolved to pursue efforts to limit the global temperature increase to 1.5°C that “requires rapid, deep and sustained reductions in global greenhouse gas emissions, including reducing global carbon dioxide emissions by 45% by 2030 relative to the 2010 level and to net zero around mid-century, as well as deep reductions in other greenhouse gases”. Consequently, we do not advocate for policies that undermine the Paris Agreement or discount Nationally Determined Contributions (NDCs).

•Business has a vital role in addressing and managing the risks and uncertainties of climate change and driving emissions to net zero. A range of policy measures is necessary to support the early movers in our sector that innovate and deploy low-carbon technology. Our policy principles provide a common architecture for the

positions we take in different jurisdictions – policy should be effective, fair, pragmatic, market-based and support free trade.

•A market-based price on carbon is the most effective way to incentivise the private sector to make low-carbon investments and drive down emissions. Based on our current assumptions, carbon prices below $100 /tCO2e may be enough for us to decarbonise power and support our investment in renewable generation and firming infrastructure. Higher carbon prices and other forms of support are necessary to address harder-to-abate parts of our carbon footprint, such as process heat and carbon anodes, and remain commercially competitive in a global market.

•Minerals and metals are globally traded, so effective climate policy should incentivise the private sector to invest in low-carbon technology without undermining the competitiveness of trade-exposed industries and shifting production, jobs and supply chains to countries with lower emissions standards (carbon leakage). If there is significant regional variation in carbon prices, carbon border adjustment mechanisms (CBAM), or alternative policies, are necessary to limit leakage, provided they can be executed pragmatically and effectively.

•Carbon pricing, on its own, might not be sufficient to transform the metals sector. Other policy tools are necessary to tackle emissions and simultaneously achieve objectives related to industrial policy. These can include:
– grant funding, tax incentives and investment incentives to support R&D, innovation and first-of-a-kind projects
– product standards and procurement obligations (such as minimum and rising requirements for low or zero carbon metal) that drive deployment of pre-commercial technology.

Rio Tinto acquires high-grade scandium project in Australia

28 April 2023

MELBOURNE, Australia--(BUSINESS WIRE)-- Rio Tinto has entered into a binding agreement to acquire the Platina Scandium Project, a high-grade scandium resource in New South Wales, from Platina Resources Limited (ASX: PGM) for $14 million.

The project, near Condobolin in central New South Wales, comprises a long life, high-grade scalable resource that could produce up to 40 tonnes per annum of scandium oxide, for an estimated period of 30 years.

Rio Tinto currently produces scandium oxide from titanium dioxide production waste streams at Sorel-Tracy in Quebec. Once operational, the Platina Scandium Project would enable Rio Tinto to more than double its annual scandium production.

This acquisition aligns with Rio Tinto’s strategic goal to grow in materials essential for the low-carbon transition.

Scandium is a rare, versatile and useful mineral for the green economy and energy transition. It is considered a critical mineral by the United States, Canada, Australia and many other countries.

Scandium is one of the most effective elements able to strengthen aluminium, while also offering improved flexibility and resistance to heat and corrosion. As a result, it is used to produce high-performance aluminium alloys for applications that need to be light, strong and heat resistant, including in aerospace, automotive, heat exchangers, sporting goods, 3D printing and energy transmission applications.

Scandium oxide is also used to improve the performance of solid oxide fuel cells used as a green power source for buildings, medical facilities and data processing centres, as well as in niche products such as lasers and lighting.

Rio Tinto Minerals Chief Executive Sinead Kaufman said “This acquisition supports our commitment to critical minerals and finding better ways to provide materials the world needs.

“It will enable us to further develop and grow with the global scandium market, complementing our existing scandium production in Quebec, where we have the expertise, technology and capacity to produce pure, highly reliable scandium through sustainable methods.”

With its world-class aluminium business, Rio Tinto is also well positioned to produce more high-performance aluminium-scandium alloys to meet global customers’ needs. To learn more, visit www.elementnorth21.com.

The transaction is expected to be completed in the first half of 2023.
