**Rio Tinto extracts first gallium from its alumina refining process with partner Indium Corporation**

07 May 2025

SAGUENAY, Canada--(BUSINESS WIRE)-- Rio Tinto and its new partner Indium Corporation have successfully extracted the first primary gallium as part of a research and development project, which ultimately aims to produce commercial quantities of the critical and strategic mineral present in the bauxite processed in Rio Tinto's Vaudreuil alumina refinery in Quebec, the only one in Canada.

This preliminary step was done in Indium Corporation's research and development facility located in Rome, New York.

The next phase of the project involves the assessment of extraction techniques to enable the production of larger quantities of gallium at pilot-scale. If successful, Rio Tinto plans to build a demonstration plant in Saguenay-Lac-Saint-Jean, financially supported by the government of Quebec, with a capacity of up to 3.5 tonnes of gallium per year. The transition to a commercial-scale plant could see production reach 40 tonnes annually, representing between 5 and 10% of current world gallium production.

Jérôme Pécresse, Chief Executive, Rio Tinto Aluminium, said: ''We are very proud to announce this significant milestone in our important research and development project to extract gallium from our aluminium operations in Quebec. Together, through this innovative partnership, Rio Tinto and Indium Corporation strive to strengthen the North American supply chain for gallium, a critical and strategic mineral.''

Ross Berntson, President and Chief Executive Officer, Indium Corporation, added: "This achievement is a major milestone, reflecting our dedication to global industrial needs by ensuring a sustainable supply of gallium. Our joint efforts are positioning North America as a leader in critical material production."

Primary gallium is used in key sectors including the manufacture of integrated circuits vital to modern technologies such as high-performance radar, smartphones, electric cars and laptops. Gallium is produced in limited quantities globally with only an estimated 600 metric tonnes per year, all from outside North America.

In addition to aluminium, copper, iron ore and titanium dioxide, Rio Tinto already produces a wide range of critical minerals in its North American facilities, including scandium used in aluminium alloys, tellurium for solar panels, lithium for EV batteries and molybdenum for steel alloys. Other research and development initiatives are ongoing to evaluate the possibility of extracting new materials from the company's existing operations and reinforcing the supply chain for these materials.

**Rio Tinto and Sumitomo Metal Mining sign Definitive Agreement for Winu Project joint venture**

12 May 2025

PERTH, Australia--(BUSINESS WIRE)-- Rio Tinto and Sumitomo Metal Mining Co (SMM) have signed the final joint venture agreements to deliver the Winu copper-gold project, located in the Great Sandy Desert region of Western Australia.

Sumitomo Metal Mining Director, Managing Executive Officer, and General Manager of the Mineral Resources Division Hideyuki Okamoto and Rio Tinto Copper Chief Executive Katie Jackson sign the Winu joint venture agreements in Perth.

The final joint venture agreements were signed in Perth by Rio Tinto Copper Chief Executive Katie Jackson and SMM Director, Managing Executive Officer, and General Manager of the Mineral Resources Division Hideyuki Okamoto. It comes after the two companies signed a Term Sheet in December 2024 to form the joint venture.

The Winu project is an attractive low-risk, long-life copper-gold deposit discovered by Rio Tinto in 2017. It is considered highly prospective for expansion beyond the initial development.

Rio Tinto Copper Chief Executive Katie Jackson said: "Our relationship with SMM began in 2000 with our partnership at the Northparkes mine in New South Wales and we look forward to bringing our combined experience and expertise to deliver the Winu project.

"This partnership is an excellent fit for Rio Tinto and will strengthen the project, as we continue to prioritise the strong and enduring partnerships built to date with the land's Traditional Owners, the Nyangumarta and the Martu."

SMM Director, Managing Executive Officer, and General Manager of the Mineral Resources Division Hideyuki Okamoto said: "We are very excited to renew our long-standing partnership with Rio Tinto, and to leverage our extensive collective experience to realise the exceptional potential of the Winu project."

Under the agreements, Rio Tinto will continue to develop and operate Winu, and SMM will pay Rio Tinto up to $430.4 million for a 30% equity share of the project. This includes $195 million up front and up to $235.4 million in deferred considerations contingent on future milestones.

The parties will also continue to work together to develop a broader strategic partnership to explore opportunities for commercial, technical and strategic collaboration across copper, other base metals and lithium.

The transaction is expected to close in 2025, subject to regulatory approvals and the satisfaction of customary conditions.

**Rio Tinto invests to modernise century-old hydroelectric power plant in Quebec**

15 May 2025

ALMA, Canada--(BUSINESS WIRE)-- Rio Tinto is investing US$1.2 billion (CA$1.7 billion) to modernise its Isle-Maligne hydroelectric power plant, commissioned in 1926 in Alma, Quebec. This is Rio Tinto's largest single investment in its hydroelectric assets since the 1950s.

The power plant modernisation is essential to secure the future of low-carbon aluminium production in Saguenay–Lac-Saint-Jean, supporting the jobs of employees across the region. It will allow Rio Tinto to protect its assets for the long term, ensure a more efficient, safe and reliable power supply of renewable energy to smelters, casting houses and other facilities, and maintain safe operations for its employees and the community.

The project will run until 2032, with an estimation of more than 300 people working on the site at its peak. It includes replacing eight turbine-alternator groups, rehabilitating their water intake and hydraulic passage, building an extension and mechanical workshop to the north of the power station, replacing electrical and mechanical equipment, and modifying a spillway so that it can be used reliably in winter.

Rio Tinto Aluminium's Managing Director for Atlantic Operations, Sébastien Ross said: "The Isle-Maligne hydroelectric power plant has been a strategic asset for Rio Tinto for 100 years, drawing on the expertise and dedication of multiple generations of employees and business partners. This major investment to modernise our facilities will ensure the long-term future and competitivity of our low carbon aluminium production in Quebec for decades to come for our Canadian and American customers.''

This investment is in addition to previously announced projects worth a combined $183 million (CA$252 million) for the refurbishment of butterfly valves and work on two other turbine-alternator groups at the Isle-Maligne power plant.

Rio Tinto is one of Canada's largest private producers of hydroelectricity. Seven hydroelectric facilities located in Quebec and British Columbia provide a competitive advantage, allowing the company's modern aluminium smelters to produce some of the lowest carbon aluminium in the world. An eighth power station supplies hydropower to Rio Tinto IOC's port operations in Sept-Îles, Quebec.

**Rio Tinto to start early works and final studies to increase Amrun mine's bauxite production on Queensland's Cape York Peninsula**

22 May 2025

MELBOURNE, Australia--(BUSINESS WIRE)-- Rio Tinto will begin early works and conduct final engineering studies to increase production capacity at the Amrun bauxite mine on Cape York Peninsula in Far North Queensland, aiming for first output as early as 2029.

The project, named *Kangwinan* at the request of Traditional Owners, the Wik Waya people, will involve building a new mine and expanding the existing port to almost double bauxite production from Rio Tinto's Weipa Southern operations, where Amrun is located.

Production from the Kangwinan project would replace output from the Andoom mine in Cape York and the Gove mine in the Northern Territory, which are both expected to close toward the end of the current decade.

Rio Tinto Pacific Operations Aluminium Managing Director Armando Torres said: "This feasibility study will explore a new bauxite operation at our Weipa Operations and represents a strong vote of confidence in the world-class bauxite deposits on the Western Cape York Peninsula, our bauxite operations, and the local community.

"It's an important step toward securing the long-term future of our operations at Cape York, and the benefits that mining brings to communities in the region, while ensuring security of supply to our Australian refineries and to our customers."

If approved, the project will establish a mining centre 15 kilometres south-east of Amrun, which was constructed at a cost of US$1.9 billion and opened in 2018. The proposed expansion would increase annual bauxite production capacity from Rio Tinto's Weipa Southern operations, by up to 20 million tonnes, in addition to the current 23 million tonnes, and expand export capacity through the Amrun port. This would largely replace the tonnages lost when Gove and Andoom come to the end of their mine lives.

Kangwinan will generate more than 800 jobs in construction and would maintain the workforce currently employed at Weipa's mines slated for closure.

The approved early works include building a 250-room camp at Amrun Village to house construction workers and developing an initial access road to the Kangwinan area.

A final investment decision is due in 2026, subject to cultural heritage consultation with Traditional Owners, completing engineering, cultural heritage and environment studies, as well as securing regulatory and other approvals.

------

**Additional information**

Kangwinan is a protector of all sacred, ceremonial and female protocols of the Wik Waya tribe. It is also the name of the black female crow, a totem of the Wik Waya people.

Rio Tinto operates an integrated aluminium value chain in Australia and New Zealand which starts with bauxite mined at Weipa, refined into alumina at Gladstone, Queensland then turned into aluminium at smelters in Queensland, New South Wales, Tasmania and New Zealand. Companies now owned by Rio Tinto began bauxite mining in Cape York, Queensland in 1963. The current mines supply Rio Tinto Aluminium's Yarwun and QAL refineries and export customers in China.

This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20250522021914/en/

![image_1.jpg](image_1.jpg)

Rio Tinto's strong lithium pipeline of assets and options in South America

------

Rio Tinto Chief Executive Jakob Stausholm said: "We are honoured to have been selected by ENAMI as the preferred partner for the Salares Altoandinos project, which has the potential to be a world-class lithium development.

"We welcome the opportunity to develop our partnership with ENAMI, building on our interests in Nuevo Cobre and Salar de Maricunga, and to support Chile's position as one of the world's leading producers of minerals critical to the energy transition."

Under the terms of the proposal, Rio Tinto would acquire an initial 51% stake in the project with ENAMI holding the remaining 49%. The transaction remains subject to the signature of binding agreements, receipt of all regulatory approvals and the satisfaction of other customary closing conditions.

**Building a world-class lithium business**

Rio Tinto is advancing its world-class lithium business and establishing itself as a global leader in the supply of energy transition commodities.

With a strategic pipeline of tier 1 lithium assets and options, including those from the recent acquisition of Arcadium Lithium, Rio Tinto now holds one of the world's largest lithium portfolios.

An expanding South American pipeline complements the projects in Canada and Serbia. This includes (see full detail in the table below):

**Chile**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Altoandinos – a new partnership with ENAMI

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Maricunga – a new partnership with Codelco

**Argentina**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Rincon, Olaroz, Fenix, Sal de Vida and Cauchari

**Long-term outlook for lithium**<sup>1</sup> Rio Tinto has been consistent in its belief in the long-term outlook for lithium, with an expected market deficit emerging from the end of this decade. It expects a more than 10% compound annual growth rate for demand through to 2040.

With spot lithium prices down more than 80% versus peak prices, these additions to the portfolio come at a time with substantial long-term market and portfolio upside, underpinned by an appealing market structure and established jurisdictions.

<sup>1</sup> *Benchmark Mineral Intelligence (BMI) benchmark supply and demand forecast as of September 2024.*

**Rio Tinto's expertise enables it to unlock value through:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• an established footprint in the Lithium Triangle to maximise synergies across the value chain

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a strong balance sheet and a mid-term capex guidance of $10-11bn per year to deploy capital where it will get the best return for shareholders

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• its approach to being Best Operator through operational excellence and leading lithium technologies including 28 years of Direct Lithium Extraction (DLE) experience

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• excellence in exploration and project delivery credentials in line with its excel in development priority

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Impeccable ESG including a commitment to deep engagement with local communities, minimizing freshwater consumption and a commitment to brine reinjection studies to reduce the impact of lithium extraction operations.

In Chile, the enormous potential of the Atacama region will enable it to develop, subject to studies, a world class copper and lithium district, which could benefit from synergies through its partnerships to unlock the potential of the region. The vision in Argentina is to develop its existing operations into super-hubs at significant scale and competitiveness.

Its approach will leverage investments in common infrastructure, such as power and logistics, across multiple projects. It will drive an integrated, coordinated approach to strengthen engagement with local communities with the strong support of partners with local experience, the minimization of freshwater consumption through recycling, and the use of processing and re-injection technologies that maximise the recovery of lithium with the lowest environmental footprint.

Rio Tinto looks forward to working with its partners in South America and will continue to evaluate Tier 1 opportunities globally as it gains momentum in building a world-class lithium business.

Our report on payments to governments made by Rio Tinto and its subsidiary undertakings for the year ended 31 December 2024 as required under the UK's Report on Payments to Governments Regulations 2014 (as amended in December 2015) has been filed at Companies House.
