Rio Tinto Chief Executive Jakob Stausholm, said: “Delivering the full potential of our assets remains a priority:
production improved versus the prior quarter across most of our sites, particularly where we have implemented the Rio Tinto Safe Production System (RTSPS). We progressed our excel in development objective,
commissioning some major projects and advancing the next tranche of Pilbara mines, agreeing to enter a joint venture with Baowu to develop Western Range and modernising the joint venture covering the Rhodes Ridge project in the East Pilbara, unlocking a pathway to develop this significant, high quality resource. We also approved growth capital for underground mining at Kennecott, early works funding at Rincon Lithium and continue to progress Oyu Tolgoi. Our proposal to take Turquoise Hill Resources private has unanimous support
of the Turquoise Hill Board who have recommended shareholders vote in favour of the transaction.
“We continue to deliver our strategy with decarbonisation at its centre. Last week we announced a partnership
with the Government of Canada to invest up to C$737 million over eight years to decarbonise our Rio Tinto Fer
et Titane operations in Québec, and to position the business as a centre of excellence for critical minerals
processing.
“We are taking action to transform our culture and rebuild trust, implementing the recommendations of the
Everyday Respect report and publishing our second progress report on our Communities and Social
Performance practices, which includes increased feedback from Traditional Owner groups, with responses from
seven groups compared to four in 2021.”

Q3 2022 operational highlights and other key announcements
• In the last quarter we exceeded four years without a fatality on a managed site. However, our all-injury
frequency rate of 0.43 has deteriorated from the third quarter of 2021 (0.40), and from the prior quarter
(0.36). We continue to prioritise the safety, health and wellbeing of our workforce and communities where
we operate.
• Pilbara operations produced 84.3 million tonnes (100% basis) in the third quarter, 1% higher than the third quarter of 2021, and 7% higher than the prior quarter with continued commissioning and ramp-up of GudaiDarri and Robe Valley. Shipments were 82.9 million tonnes (100% basis), 1% lower than the third quarter of 2021, and 4% higher than the prior quarter despite two unplanned rail outages on the Yandicoogina and Gudai-Darri lines. The investigation into the Gudai-Darri derailment is ongoing. Full year shipments are expected to be at the low end of the original 320 to 335 million tonne range.
Notice to ASX/LSE
Rio Tinto | Third quarter operations report

• On 14 September, we agreed to enter a joint venture with China Baowu Steel Group Co. Ltd with respect to
the Western Range iron ore project in the Pilbara, investing $2 billion ($1.3 billion Rio Tinto share1
) to
develop the mine. Its annual capacity of 25 million tonnes will help sustain production of the Pilbara Blend,
with construction expected to begin in early 2023 and first production anticipated in 2025. The transaction
with Baowu is subject to satisfaction of various conditions precedent, including approvals from Rio Tinto
shareholders, the Australian Government, Chinese Government regulatory agencies and the Western
Australian Government, among others.
• We have agreed, together with Wright Prospecting Pty Ltd, to modernise the joint venture covering the
Rhodes Ridge project in the East Pilbara, Western Australia. The joint venture updates an existing
agreement between the two parties dating back to 1972 and now provides a pathway for the development
of the Rhodes Ridge deposits utilising Rio Tinto’s rail, port and power infrastructure. The participants have
commenced an Order of Magnitude study, to be conducted by Rio Tinto, which will consider the
development of an operation before the end of the decade with initial plant capacity of up to 40 million
tonnes annually, subject to the receipt of relevant approvals.
• Bauxite production of 13.7 million tonnes was 2% lower than the third quarter of 2021 due to equipment
reliability issues at Gove.
• Aluminium production of 0.8 million tonnes was 2% lower than the third quarter of 2021, and 4% higher
than the prior quarter as the Kitimat smelter continues to ramp up and Boyne smelter cell recovery efforts
progress as expected. The Kitimat pot restarts are progressing but structural issues with the alumina
conveyor system caused disruptions through the quarter slowing the rate of pot restarts. We continue to
focus on full recovery during the course of 2023.
• Mined copper production of 138 thousand tonnes was 10% higher than the third quarter of 2021 due to
higher grades and recoveries at Kennecott, partly offset by lower grades and recoveries at Oyu Tolgoi as a
result of planned mine sequencing. Refined copper production guidance has been reduced to 190 to 220
thousand tonnes (previously 230 to 290 thousand tonnes), given further downside risk associated with
Kennecott’s smelter and refinery performance, until we undertake the largest rebuild in nine years which is
planned for the second quarter of 2023.
• On 27 September, we announced approval of $55 million in development capital to start underground
mining and expand production at Kennecott. This will initially focus on the Lower Commercial Skarn area,
which will deliver a total of around 30 thousand tonnes
2
of additional copper through the period to 2027
alongside open cut operations. The first ore is expected to be produced in early 2023, with full production in
the second half of the year. Underground battery electric vehicles are currently being trialled at Kennecott to
improve employee health and safety, increase productivity and reduce carbon emissions from future
underground mining fleets.
• On 5 September, we entered into a binding agreement to acquire all of the remaining shares of Turquoise
Hill Resources that Rio Tinto does not currently own, subject to shareholder approval. The transaction
delivers significant value to Turquoise Hill minority shareholders with the certainty of an all-cash offer of
C$43 per share (with a total cash consideration of $3.3 billion), and provides greater certainty of funding for
the long-term success of the Oyu Tolgoi project.
• Titanium dioxide slag production of 310 thousand tonnes was 48% higher than the third quarter of 2021,
due to community disruptions at Richards Bay Minerals in South Africa in 2021, and continued improved
performance of operations at Rio Tinto Fer et Titane (RTFT), Canada.
• Iron Ore Company of Canada (IOC) production of pellets and concentrate was 28% higher than the third
quarter of 2021 due to improved operational performance as well as timing of the planned annual maintenance shutdown (seven days) which was successfully completed in June (this work was completed
in September in 2021).
• This quarter marked 12 months since we began the roll-out of the Rio Tinto Safe Production System (RTSPS). We now have 22 deployments at 13 sites and 63 rapid improvement projects (Kaizens) completed or in progress. We are on track to meet our 2022 target of 30 deployments at 15 sites.
