Note:

As at the date of this announcement:

(a)  Rio Tinto plc has also issued one Special Voting Share of 10p and one DLC Dividend Share of 10p in connection with its dual listed companies ('DLC') merger with Rio Tinto Limited which was designed to place the shareholders of both companies in substantially the same position as if they held shares in a single enterprise owning all of the assets of both companies;

(b)  the Special Voting Share facilitates joint voting by shareholders of Rio Tinto plc and Rio Tinto Limited on joint electorate resolutions; and

(c)  there are 371,216,214 publicly held Rio Tinto Limited shares in issue which do not form part of the share capital of Rio Tinto plc.

This announcement is authorised for release to the market by Steve Allen, Rio Tinto's Group Company Secretary.

Rio Tinto donates A$1.5 million to Queensland and New South Wales flood relief and recovery efforts

07 March 2022

MELBOURNE, Australia--(BUSINESS WIRE)--Rio Tinto has donated A$1.5 million to disaster relief and recovery efforts supporting people affected by widespread floods in Queensland and New South Wales.

The funds will help provide vital support to impacted communities and comprise of:

•A$750,000 to the Australian Red Cross’ Floods Appeal which enables volunteers and staff to help with evacuation and relief centres, as well as supporting people and communities to recover and build resilience to disasters;

•A$500,000 to BizRebuild, a Business Council of Australia initiative that provides practical and on the ground assistance to small and local businesses devastated by natural disasters.

•A$250,000 to Givit, a grassroots charity buying and delivering essential items for people affected by the floods.

Rio Tinto is also offering immediate financial support to employees directly impacted by the floods, as well as providing staff involved in recovery efforts, such as Queensland’s ‘Mud Army’, with full paid leave. In addition to this, the company will match any staff donations to flood relief causes.

Rio Tinto Chief Executive Australia Kellie Parker said “As a company with a proud connection to Queensland, where we employ thousands of people across the state, we want to support those suffering from these devasting floods.

“Australian Red Cross, BizRebuild and Givit provide crucial assistance to communities in times of crisis, and we hope our donations can support their tireless efforts caring for those affected by the floods.

“We have also made sure that any of our people directly impacted by the floods can access emergency funding if needed, while those involved in the clean-up effort are supported with full paid leave.

“In addition to the steps announced today, we will continue to explore ways to help flood-affected people and communities.”

Rio Tinto welcomes moves to strengthen cultural heritage protection

14 March 2022

MELBOURNE, Australia--(BUSINESS WIRE)-- Rio Tinto welcomes the release today of a joint Commonwealth Government and First Nations Heritage Protection Alliance DiscussionPaper designed to strengthen state and federal cultural heritage protection laws.

Rio Tinto supports strengthening safeguards for cultural heritage at both state and Commonwealth legislative levels, including the reform process currently underway to ensure an incident like the destruction of rock shelters at Juukan Gorge in Western Australia never happens again.

These reforms must ensure that Aboriginal and Torres Strait Islander peoples are placed at the centre of decision-making on matters relating to protection of their cultural heritage.

Rio Tinto Chief Executive, Australia Kellie Parker said “We have heard the call for Rio Tinto to play a greater role in the strengthening of state and Commonwealth cultural heritage protection laws.

“This call has been made by the Commonwealth Parliamentary Committee that inquired into the destruction of the Juukan Gorge rock shelters, Traditional Owners, the National Native Title Council, the First Nations Heritage Protection Alliance, and our investors. The call is reinforced in the Dhawura Ngilan Vision Statement.

“We firmly believe a co-design process with Traditional Owners will strengthen cultural heritage management and protection to ensure it is valued and celebrated for its intrinsic worth.

“There are and will be differences in views on how this will be best achieved but we will continue to work in close consultation with Traditional Owners and their representative organisations to better understand and protect their cultural heritage and ensure mining is done in the right way.”

Last month, Rio Tinto developed a joint management plan with the Yinhawangka Aboriginal Corporation in Western Australia. This plan ensures the protection of significant social and cultural heritage values, as part of the proposed development of the Western Range iron ore project in the Pilbara. It is the result of a strong collaboration between the Yinhawangka people and Rio Tinto.

Kellie Parker said: “Our determination not to repeat the events leading up to the destruction of the Juukan Gorge rock shelters is ingrained in everything we do.

“Significant changes continue to be made at all levels of our business. While we are hopeful we have put in place the right foundations for a better future, we know we will be judged by our actions and not our words.”

Notice to ASX/LSE 29 March 2022 Rio Tinto completes acquisition of Rincon lithium project Rio Tinto has completed the acquisition of the Rincon lithium project in Argentina for $825 million, following approval from Australia’s Foreign Investment Review Board (FIRB). A binding agreement to purchase the project from Rincon Mining, a company owned by funds managed by the private equity group Sentient Equity Partners, was announced in December 2021. Rincon is a large undeveloped lithium brine project located in the heart of the lithium triangle in the Salta Province of Argentina, an emerging hub for greenfield projects. The project is a long life, scaleable resource capable of producing battery grade lithium carbonate. It has the potential to have one of the lowest carbon footprints in the industry. Rio Tinto Chief Executive Jakob Stausholm said “Rincon strengthens our battery materials business and positions Rio Tinto to meet the double-digit growth in demand for lithium over the next decade, at a time when supply is constrained. We will be working with local communities, the Province of Salta and the Government of Argentina as we develop this project to the highest ESG standards.” The direct lithium extraction technology proposed for the project has the potential to significantly increase lithium recoveries as compared to solar evaporation ponds. A pilot plant is currently running at the site and further work will focus on continuing to optimise the process and recoveries. The market fundamentals for battery grade lithium carbonate are strong, with lithium demand forecast to grow 25-35% per annum over the next decade with a significant supply demand deficit expected from the second half of this decade.

Rio Tinto commissions new aluminium remelt furnace at Laterrière Plant

29 March 2022

SAGUENAY, Canada – Rio Tinto has commissioned a new remelt furnace at its Laterrière Plant, adding 22,000 metric tons of recycling capacity to its aluminium operations in the Saguenay – Lac-Saint-Jean region of Quebec. 

The $8.4-million project has been completed over two years to offer rolled product customers in the North American automotive and packaging industries a new sustainable supply solution combining low-carbon and recycled aluminium. 

The remelt furnace is equipped with highly efficient burners to minimize its carbon footprint. The project has created seven new jobs. 

Rio Tinto Aluminium managing director Atlantic Operations Sébastien Ross said: “Aluminium is 100% recyclable and the demand for recycled metal is continually growing. With the commissioning of our new remelt furnace, we are now offering our customers an additional solution to recycle scrap from their manufacturing processes and turn it into high quality, low carbon aluminium alloys. Rio Tinto will continue working closely with our customers and partners to support the transition to a circular economy.” 

The rolled product recycling service complements the closed looped solution Rio Tinto introduced for  billet customers in 2021. Rio Tinto’s technical marketing experts are available to assist customers in selecting the right recycled content together with the optimal alloy for their specific needs.

Notes to editors

Rio Tinto is an industry leader in responsible aluminium production, with operations in Canada run on 100% renewable hydropower. In 2016, Rio Tinto launched RenewAl, the world’s first certified low CO2 primary aluminium brand. 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. Looking to the future, ELYSIS, Rio Tinto’s partnership with Alcoa supported by Apple and the governments of Canada and Quebec, is scaling-up a revolutionary new direct greenhouse emissions free aluminium smelting technology.
