Rio Tinto and Salzgitter sign MOU to study using Rio Tinto iron ore in green steelmaking

MELBOURNE--(BUSINESS WIRE)-- Rio Tinto and the Salzgitter Group have signed a Memorandum of Understanding (MOU) to work together towards carbon-free steelmaking by studying optimisation of Rio Tinto’s high-quality Canadian and Australian iron ore products for use in Salzgitter’s SALCOS green steel project in Germany.

Under the MOU, Rio Tinto and Salzgitter will explore optimisation of iron ore pellets, lump and fines for use in hydrogen direct reduction steelmaking. The two companies will also explore the potential for greenhouse gas emission certification across the steel value chain.

Rio Tinto produces iron ore pellets and concentrate at Iron Ore Company of Canada and iron ore lump and fines in Western Australia’s Pilbara region. The partnership will focus on the potential use of these products in the SALCOS® - Salzgitter Low CO2 Steelmaking programme, which is targeting virtually carbon-free steel production, starting step-by-step in 2025 using hydrogen direct reduction.

Rio Tinto Chief Commercial Officer Alf Barrios said “We welcome the chance to work with Salzgitter on ways to accelerate green steelmaking, in keeping with our commitment to reduce emissions across the steel value chain.

“Salzgitter has one of the world’s most advanced green steelmaking projects. Rio Tinto is excited at the opportunity of supplying our product and combining our technical expertise with that of Salzgitter to help advance the SALCOS project.”

Salzgitter Flachstahl GmbH Chairman of the Management Board Ulrich Grethe said “With this alliance, we want to combine the knowledge of both companies to make further progress with low-carbon steel production.

“In this context, the Salzgitter Group is relying on strong partners, as set out in our ‘Salzgitter AG 2030’ Group strategy, in line with its motto of ‘Partnering for Circular Solutions’.”

Rio Tinto is committed to reaching net zero emissions by 2050 and is targeting a 15% reduction in Scope 1 & 2 emissions by 2025 (from a 2018 baseline) and a 50% reduction by 2030. Rio Tinto’s approach to addressing Scope 3 emissions is to engage with its customers on climate change and work with them to develop the technologies to decarbonise.

Under the SALCOS program, Salzgitter’s carbon-based blast furnace route will gradually be replaced from the middle of this decade by direct reduction plants, initially operated by natural gas and then with a steadily increasing proportion of hydrogen.

Notice to ASX/LSE 15 June, 2022 First ore delivered at Gudai-Darri iron ore mine in the Pilbara Rio Tinto has delivered first ore from the Gudai-Darri iron ore mine as the company brings online its first greenfield mine in the Pilbara, Western Australia, in more than a decade. Gudai-Darri will help underpin future production of the company’s flagship Pilbara Blend™ product. The first autonomous AutoHaul™ trains loaded with ore from Gudai-Darri’s process plant have travelled the new 166- kilometre rail line that connects to Rio Tinto’s existing rail and port infrastructure. Production from the mine will continue to ramp up through the remainder of this year and is expected to reach full capacity during 2023. Since ground was broken in April 2019, more than 14 million workhours have resulted in the movement of over 20 million cubic metres of earth, batching and placement of 35,000 cubic metres of concrete, and the installation of 10,000 tonnes of steel. The development of Gudai-Darri supported more than 3,000 jobs during the construction and design phase. The mine will support around 600 ongoing permanent roles. With an expected life of more than 40 years and an annual capacity of 43 million tonnes, Gudai-Darri will underpin future production of Pilbara Blend™ product. A feasibilty study to support an expansion of this new hub is also progressing. The mine’s commissioning and ramp-up is expected to increase Rio Tinto’s iron ore production volumes and improve product mix from the Pilbara in the second half of this year. Full-year shipments guidance for 2022 remains at 320 to 335 million tonnes (100% basis) subject to risks around the ramp up of new mines, weather and management of cultural heritage. The capital cost for the mine is estimated to be $3.1 billion (A$4.3 billion). As disclosed in February, the company’s replacement projects in the Pilbara, including Gudai-Darri, were subject to potential capital increases of approximately 15% due to ongoing COVID-19 restrictions, including labour access and supply chain quality issues. Group capital expenditure guidance for 2022 is unchanged at around $8 billion. Rio Tinto Iron Ore Chief Executive Simon Trott said “The commissioning of Gudai-Darri represents the successful delivery of our first greenfield mine in over a decade, helping to support increased output of Pilbara Blend, our flagship product. It sets a new standard for Rio Tinto mine developments through its deployment of technology and innovation to enhance productivity and improve safety. “I’d like to acknowledge the support of the Traditional Owners, the Banjima People, on whose country Gudai-Darri is situated. We have worked closely with the Banjima People to progress this project and we look forward to continuing to actively partner with them into the future.” Rio Tinto Chief Technical Officer Mark Davies said “The safe and successful delivery of Gudai-Darri, in the midst of a global pandemic, is testament to the resilience and hard work of thousands of Rio Tinto employees and contractors, including a range of local Western Australian suppliers, as well as Pilbara Aboriginal businesses. “In building this new hub we have brought together the best of our innovations, including autonomous trucks, trains and drills, as well as the world’s first autonomous water trucks, to make Gudai-Darri our most technologically advanced iron ore mine. EXHIBIT 99.4

Notice to ASX/LSE Page 2 of 3 “This suite of autonomous assets complements the planned deployment of other leading-edge technologies including a robotic ore sampling laboratory, field mobility devices for all personnel and a digital asset of the fixed plant, which, together with data analytics, will make Gudai Darri safer and more productive.” Helping support Rio Tinto’s carbon emission reduction targets, Gudai-Darri will be powered by a 34 megawatt solar farm that is expected to supply about a third of the mine’s average electricity demand once construction is complete in August. Together with a new lithium-ion battery energy storage system in Tom Price, the solar plant is estimated to reduce annual carbon dioxide emissions by about 90,000 tonnes compared to conventional gas powered generation, equivalent to taking about 28,000 cars off the road.

In collaboration with Caterpillar, Rio Tinto is advancing the development of zero-emissions autonomous haul trucks. Once development is complete, it is anticipated the world’s first operational deployment of Caterpillar 793 zero-emissions autonomous haul trucks will be at Gudai-Darri.

The world’s first autonomous water carts

oThe new vehicles, developed in partnership with Caterpillar, are primarily used for dust suppression on site, enhancing productivity by enabling mine operations to digitally track water consumption and reduce waste. The vehicle’s intelligent on-board system detects dry and dusty conditions on site, triggering the application of water to roads to keep them in good condition.

Autonomous trains (AutoHaul™)

oFully operational in June 2019, AutoHaul™ was the world’s first fully autonomous long distance, heavy-haul rail network. The autonomous train is monitored

remotely by operators from our Operations Centre in Perth more than 1,500 kilometres away.

Rio Tinto’s first rotable bucketwheel reclaimer

oTraditionally reclaimer maintenance requires a prolonged shutdown while several components are removed. This patented world first will enable the entire bucket wheel module to be changed out for maintenance, improving safety and efficiency.

Robotic ore sampling laboratory

oThe Gudai-Darri laboratory is fully automated and integrated with our mine. Production samples (both lump and fines) enter the lab via a conveyer from the sample station and will be transferred to the automated production cell by a robot. This facility will provide excellent visibility of the ore grade being stockpiled on site.

Robotics in Heavy Mobile Equipment warehouse

oThe heavy mobile equipment (HME) warehouse is the home to four automatic guided vehicles (AGVs) designed to automate the handling of pallet frames. The introduction of AGV’s to the warehouse will reduce manual handling and improve safety with the introduction of laser obstacle scanners and auto stop functions.

Paperless field mobility

oWe are using technology to provide our people with in-field access to real-time data - connecting our teams to each other, to our work and our assets. Through tablets, team members can access many of the applications they require out in the field thereby eliminating the need for paper-based systems and reducing unnecessary travel.

‘Digital twin’ asset

oOur digital asset will be a first within Rio Tinto and will enable our team members to visually navigate the asset, plan their work using a (to scale) 3D model and view or download associated technical data and documents. The same digital asset data is used to provide a feature rich, interactive 3D environment for virtual reality training.

Solar farm

oThe solar farm consists of about 83,000 solar panels made up of photovoltaic cells to convert sunlight into electricity. Capacity is up to 34MW and is expected to supply about a third of the mine’s average electricity demand once construction is complete in August.

Media Release

Rio Tinto and Corona Canada pilot Canada’s first specially-marked low carbon can leveraging ELYSIS technology

29 June 2022

MONTREAL--(BUSINESS WIRE)-- Rio Tinto today announced, in partnership with Corona Canada, the launch of Canada’s first specially-marked, low carbon beverage can, manufactured by Ball Corporation. The cans, now available through a pilot in Ontario, were made using aluminium from Rio Tinto and leveraging ELYSISTM technology. As part of this limited release, 1.2 million cans were produced with a QR code to inspire consumers to learn more about the cans’ low carbon footprint.

This pilot is a step towards putting a fully traceable beverage can in the hands of consumers. In the future, Rio Tinto will leverage insights from its START initiative to allow consumers to use QR codes to see exactly how their products were made from mine to market – including sustainability data.

Currently, around 70 per cent of the aluminium used in cans produced in North America is made with recycled aluminium (1). Pairing this recycled metal with Rio Tinto’s low-carbon aluminium – made with renewable hydropower – and metal produced using the direct greenhouse gas emissions free ELYSISTM smelting technology reduces carbon emissions by more than 30 per cent (2).

Corona Canada’s Marketing Vice President Andrew Oosterhuis said: “As a brand, Corona believes we have a responsibility to be an ally to our environment, recognizing that change needs to start within our own production lines as a tangible way we can help protect paradise and reach our ambitious sustainability goals. By continuing to introduce market-leading technologies in the beverage space, we’re leading by example for other companies and their suppliers to innovate and drive meaningful change for our environment.”

Rio Tinto’s Head of Sales and Marketing Tolga Egrilmezer said: “Leveraging insights from START, we look forward to putting more information into the hands of consumers, so they can see how we are partnering with leading brands like Corona to help deliver more sustainable supply chains and products. These specially-marked, low carbon beverage cans will showcase the responsibly produced aluminium Rio Tinto delivers, bringing together renewable hydropower and the innovation of zero carbon ELYSISTM smelting technology.”

This launch builds on a Memorandum of Understanding signed in 2020 between Rio Tinto and Corona Canada’s parent company Anheuser-Busch InBev (AB InBev), to work with supply chain partners to bring AB InBev products to market in cans made from aluminium that meets industry-leading sustainability standards.

The cans are now available through LCBO and select grocery stores in Ontario, while supplies last.

Notes to editors

ELYSIS is a technology company created through a partnership between aluminium industry leaders Rio Tinto and Alcoa, with support from Apple and the governments of Canada and Quebec. ELYSIS is scaling up a revolutionary technology that enables the production of metal without direct carbon dioxide emissions during the aluminium smelting process, instead emitting pure oxygen. The technology uses inert anodes to replace the carbon anodes traditionally used during electrolysis, the process used to make primary aluminium. Learn more at www.elysis.com.

In 2021, Rio Tinto launched START, a new standard in transparency, traceability and provenance for the aluminium industry. Using secure blockchain technology, START provides key information about how Rio Tinto aluminium was made, covering ten criteria: carbon footprint, water use, recycled content, energy sources, community investment, safety performance, diversity in leadership, business integrity, regulatory compliance and transparency. Through START, Rio Tinto empowers its customers and theirs to make a more sustainable choice.
