 Operational update 
 --   Pilbara iron ore shipments of 86.1 million tonnes (100% basis) 
       in the third quarter were 5% higher than the third quarter 
       of 2018. Pilbara iron ore production of 87.3 million tonnes 
       (100% basis) was 6% higher than the third quarter of 2018 
       and 10% higher than the previous quarter, reflecting a good 
       recovery from the operational and weather challenges experienced 
       earlier in the year. 
 --   Third quarter bauxite production and shipments to third parties 
       were 9% and 23% higher, respectively, than the same period 
       of 2018. Bauxite production from non-managed Joint Ventures 
       was lower than planned year to date. 
 --   Aluminium production of 0.8 million tonnes was 3% lower than 
       the third quarter of 2018, primarily reflecting a preventive 
       safety shutdown at one of the three pot-lines at ISAL in Iceland 
       and earlier than planned pot relining at Kitimat in British 
       Columbia, Canada. 
 --   Mined copper production of 158 thousand tonnes was 1% lower 
       than the third quarter of 2018, but 15% higher than the second 
       quarter, reflecting higher grades at Kennecott and improved 
       throughput at Escondida. 
 --   At the Oyu Tolgoi underground project, the primary production 
       shaft (shaft 2) remains on track for commissioning this month. 
       Since July 2019, we have completed key infrastructure, including 
       the central heating plant, the shaft 2 jaw crusher system 
       and the surface discharge conveyor. Work continues on the 
       mine re-design. 
 --   Titanium dioxide slag production of 321 thousand tonnes was 
       8% higher than the third quarter of 2018, reflecting a continued 
       improvement in operational performance and the restart of 
       furnaces in 2019. 
 --   Third quarter production at Iron Ore Company of Canada was 
       3% higher than the corresponding quarter of 2018 and 17% higher 
       than the previous quarter, reflecting a return to normal operating 
       conditions following the flooding incident which impacted 
       June. 
 --   Guidance is unchanged, with the exception of bauxite production, 
       which has been revised to around 54 million tonnes (previously 
       56 to 59 million tonnes), and alumina production, which has 
       been revised to around 7.7 million tonnes (previously 8.1 
       to 8.4 million tonnes). 
 --   On 25 September 2019, Rio Tinto announced the signing of a 
       Memorandum of Understanding with China Baowu Steel Group and 
       Tsinghua University to develop and implement new methods to 
       reduce carbon emissions and improve environmental performance 
       across the steel value chain. 
 --   Third quarter exploration and evaluation spend was $177 million, 
       62% higher than the same period of 2018, primarily reflecting 
       increased activity on advanced projects. 
 

All figures in this report are unaudited. All currency figures in this report are US dollars, and comments refer to Rio Tinto's share of production, unless otherwise stated. To allow production numbers to be compared on a like-for-like basis, production from asset divestments completed in 2018 is excluded from Rio Tinto share of production data.

Pilbara operations

Third quarter production of 87.3 million tonnes (Rio Tinto share 72.2 million tonnes) was 6% higher than the same quarter of 2018 and 10% higher than the previous quarter. This reflects a solid performance in the mines, with actions progressing as planned. Our increased focus on waste material movement and pit development will continue over 2019 and 2020 to improve mine performance and pit sequencing. Our cost guidance (below) reflects these additional mining activities.

A planned rail maintenance shut was executed late in the third quarter, starting on 25 September and completed on 6 October. Our cost and shipments guidance take into account the impact of this activity.

Third quarter sales of 86.1 million tonnes (Rio Tinto share 71.6 million tonnes) were 5% above the third quarter of 2018 and 1% higher than the previous quarter.

We sold 6.7 million tonnes of alternate products in the third quarter. These are included in the above sales figures. We expect to make additional sales of these products in the fourth quarter.

The majority of our iron ore shipments are priced by reference to the average index price for the month of shipment. We priced approximately 16% of sales in the first nine months of 2019 by reference to the prior quarter's average index lagged by one month, with the remainder sold either on current quarter average, current month average or on the spot market.

Pilbara projects

The Koodaideri iron ore mine is progressing to plan with engineering, procurement and construction activities on schedule. Preparatory works have commenced. We expect to produce first ore from Koodaideri in late 2021, consistent with previous guidance.

First ore from the Robe River Joint Venture sustaining production projects (West Angelas C&D and Mesa B, C and H at Robe Valley) is also anticipated in 2021, consistent with previous guidance. West Angelas received all regulatory approvals in early October 2019, and project construction has commenced. The Robe Valley projects continue to progress through the environmental and heritage approval processes. We are experiencing some delays for Mesa H environmental approvals.

2019 guidance

Our 2019 Pilbara shipments guidance is unchanged at between 320 and 330 million tonnes (100% basis), subject to weather.

Our iron ore unit cost guidance in 2019 remains at $14 - $15 per tonne.

Bauxite

Third quarter bauxite production was 9% higher than the same period of 2018, with increased production across all sites.

We shipped 10.4 million tonnes of bauxite to third parties in the third quarter, 23% higher than the same period of 2018.

Alumina

Third quarter alumina production was 7% below the same period of 2018. Production at Yarwun was lower due to an extended 35-day shutdown, which included a planned five-year maintenance service of the cogeneration plant. Normal production has since resumed at Yarwun. Production at the Queensland Alumina non-managed JV was impacted by maintenance activities, with the site expected to ramp back to full capacity during the fourth quarter.

A project using industry-leading filter press technology to move to bauxite residue dry stacking and extend the life of the Vaudreuil refinery in Quebec is being commissioned in October. The project commenced in February 2018 and will be commissioned six weeks ahead of plan and under its budget of $188 million (C$250 million).

Aluminium

Third quarter aluminium production of 0.8 million tonnes was 3% lower than the same period of 2018, reflecting reduced production at ISAL in Iceland and Kitimat in British Columbia, Canada. Our Quebec and Pacific smelters continue to perform well, with third quarter and year to date production 1% higher than the same periods last year. This excludes the non-managed Becancour JV where the restart is progressing well, following a lock-out, with full ramp-up expected by mid-2020.

Production at ISAL was impacted by the preventive, safety driven shutdown of one of the three potlines due to process instability. This issue has been resolved and will result in an estimated 21 thousand tonnes production loss compared to last year, of which 17 thousand tonnes was in the third quarter.

Third quarter production at Kitimat was 15 thousand tonnes lower than the same period last year due to earlier than planned pot-lining replacement. We are accelerating work to minimise further production impacts. The estimated impact on fourth quarter production is reflected in our guidance below, with the 2020 impact to be determined by pot relining needs.

The aluminium industry continues to face challenging conditions in global markets and policy uncertainty, reflected in declining prices. We are focusing on enhancing the competitiveness of our smelters, including discussions with our Pacific stakeholders on energy pricing, to ensure the sustainability and global competitiveness of our Pacific smelters.

Kemano

At the Kemano hydro-power facility at Kitimat, tunnel boring continues to progress with a total of 1,753 metres excavated as at 30 September 2019.

2019 guidance

We now expect our share of bauxite production to be around 54 million tonnes (previously 56 to 59 million tonnes), reflecting weather related events in the first quarter, downtime to address commissioning items on new mines and lower production from the Pacific refineries.

We now expect our share of alumina production to be around 7.7 million tonnes (previously 8.1 to 8.4 million tonnes) due primarily to maintenance activities in the Pacific refineries.

We expect our share of aluminium production to be at the lower end of guidance (3.2 to 3.4 million tonnes), primarily reflecting lower than planned volumes at the ISAL, Kitimat and non-managed Becancour smelters.

Rio Tinto Kennecott

Third quarter mined copper production was 2% lower than the same period of 2018, but 40% higher than the previous quarter, as mining activity moved to an area of higher grades following the low grades experienced in the second quarter.

Refined copper production was lower than comparable prior periods, reflecting reduced copper concentrate availability from the previous quarter, a planned smelter shut-down in July and additional unplanned maintenance which reduced furnace online time.

Rio Tinto Kennecott continues to toll and purchase third party concentrate to optimise smelter utilisation, with 11.9 thousand tonnes of concentrate received for processing in the third quarter of 2019, compared with 6.3 thousand tonnes in the third quarter of 2018. Purchased and tolled copper concentrate are excluded from reported production figures.

Higher molybdenum grades were sustained in the third quarter, with production of 2.1 thousand tonnes, compared with 1.4 thousand tonnes in the same quarter in 2018.

Escondida

Third quarter mined copper production at Escondida was 4% higher than the same period of 2018, mainly due to higher concentrator throughput and an increase in recoverable copper in ore stacked for leaching.

Oyu Tolgoi

Mined copper production from the open pit in the third quarter of 2019 was 28% lower than the same period in 2018 and 27% lower than the prior quarter as mining activity moved to lower grade areas of the pit, as planned.

Oyu Tolgoi Underground Project

Commissioning milestones for the primary production shaft (shaft 2) remain on target for completion in October. Rope-up of the service and production hoists was completed as planned, and testing of the braking system has also been completed.

Since July 2019, we have also completed key infrastructure, including the central heating plant, the shaft 2 jaw crusher system and the surface discharge conveyor.

As previously announced on 16 July 2019, enhanced geotechnical information and data modelling suggests there may be some stability risks with the Feasibility Study 2016 mine design and so a number of mine design options are under consideration. Work is focusing on evaluating design options, including the impact of relocation or removal of some of the planned underground infrastructure, such as the mid-access drives and the ore handling system and options for panel sequencing.

Work on the final design of the first panel of mining, Panel 0, is still anticipated to continue until early 2020 and the Definitive Estimate, which will include the final estimate of cost and schedule for the remaining underground project, is still expected to be delivered in the second half of 2020.

Resolution Copper

On 9 August 2019, Rio Tinto announced that the Resolution Copper project in the US had achieved a major permitting milestone with the release of an independently prepared Draft Environmental Impact Statement for the project. The rigorous review, conducted by the US Forest Service over a six year period, included broad public engagement.

Diamonds

At Argyle, carat production in the third quarter of 2019 was 7% lower than the same period in 2018 due to lower recovered grade, partially offset by stronger mining and processing rates.

At Diavik, carats recovered in the third quarter were 7% lower than the third quarter of 2018 due to lower ore availability from both the underground and the A21 open pit.

2019 guidance

Our 2019 guidance (Rio Tinto share) is unchanged, with mined copper production of between 550 and 600 thousand tonnes, subject to grade availability, refined copper production of between 220 and 250 thousand tonnes and diamond production of between 15 and 17 million carats.

Iron Ore Company of Canada (IOC)

Third quarter production available for sale at IOC was 3% higher than the corresponding period of 2018. It was 17% higher than the prior quarter, when production was impacted by a flooding incident in June.

Borates

Both the sodium borate and non-sodium borate refineries operated below capacity during the third quarter, aligned with market conditions. We will base any decision to increase refinery utilisation rates on maximising value over volume.

Iron and Titanium

Titanium dioxide feedstock production in the third quarter was 8% higher than the same period of 2018, reflecting improved operational performance and the restart of furnaces.

Eight of nine furnaces at Rio Tinto Fer et Titane (RTFT) are currently in operation, with three of four furnaces currently in operation at Richards Bay Minerals (RBM). This compares with six out of nine furnaces in operation at RTFT and three out of four at RBM in the third quarter of 2018. We will base our decision to re-start the remaining idled furnaces on maximising value over volume.

Zulti South project

Construction of the $463 million Zulti South project at RBM in South Africa, which was forecast to commence in June, has been delayed due to ongoing negotiations with local communities.

Uranium

Energy Resources of Australia continues to process existing stockpiles. Third quarter production was 29% lower than the same period of 2018, reflecting lower grades.

Production from Rössing Uranium is reported up to the date of completion of divestment on 16 July 2019.

2019 guidance

Our 2019 guidance (Rio Tinto share) is unchanged, with iron ore pellets and concentrate production of between 10.7 and 11.3 million tonnes, titanium dioxide slag production of between 1.2 and 1.4 million tonnes and boric oxide equivalent production of 0.5 million tonnes.

EXPLORATION AND EVALUATION

Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in the first nine months of 2019 was $464 million, compared with $341 million in the first nine months of 2018, with increased spend at Resolution Copper and on central exploration Order of Magnitude studies in Australia and North America. Approximately 53% of this expenditure was incurred by central exploration, 35% by Copper & Diamonds, 7% by Energy & Minerals and the remainder by Iron Ore and Aluminium.

There were no significant divestments of central exploration properties in the third quarter of 2019.

Exploration highlights

Rio Tinto has a strong portfolio of projects with activity in 18 countries across some seven commodities. The bulk of the exploration expenditure in this quarter was focused on copper in Australia, Canada, Chile, Kazakhstan, Mongolia, Papua New Guinea, Namibia, Peru, Serbia, United States, Zambia and diamonds projects in Canada. Mine-lease exploration continued at a number of Rio Tinto managed businesses including Pilbara Iron in Australia, Oyu Tolgoi in Mongolia, Diavik in Canada, as well as Resolution and Boron in the US. A summary of activity for the quarter is as follows:

Forward-looking statements

This announcement may include "forward-looking statements" within the meaning of the US Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts included in this announcement, including, without limitation, those regarding Rio Tinto's production forecast or guidance, financial position, business strategy, plans and objectives of management for future operations (including development plans and objectives relating to Rio Tinto's products and reserve and resource positions), are forward-looking statements. The words "intend", "aim", "project", "anticipate", "estimate", "plan", "believes", "expects", "may", "should", "will", "target", "set to", "assumes" or similar expressions, commonly identify such forward looking statements.

Such forward-looking statements involve known and unknown risks, uncertainties and other factors which may cause the actual production, performance or results of Rio Tinto to be materially different from any future production, performance or results expressed or implied by such forward-looking statements. Such forward-looking statements could be influenced by such risk factors as identified in Rio Tinto's most recent Annual Report and Accounts in Australia and the United Kingdom and the most recent Annual Report on Form 20-F filed with the United States Securities and Exchange Commission (the "SEC") or Form 6-Ks furnished to, or filed with, the SEC. Forward-looking statements should, therefore, be construed in light of such risk factors and undue reliance should not be placed on forward-looking statements. These forward-looking statements speak only as of the date of this announcement. Rio Tinto expressly disclaims any obligation or undertaking (except as required by applicable law, the UK Listing Rules, the Disclosure and Transparency Rules of the Financial Conduct Authority and the Listing Rules of the Australian Securities Exchange) to release publicly any updates or revisions to any forward-looking statement contained herein to reflect any change in Rio Tinto's expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based.

Nothing in this announcement should be interpreted to mean that future earnings per share of Rio Tinto plc or Rio Tinto Limited will necessarily match or exceed its historical published earnings per share.

Throughout this report, figures in italics indicate adjustments 
 made since the figure was previously quoted on the equivalent

 numbers shown, hence small differences may result between the 
 total of the quarter figures and the year to date figures.
