Rio Tinto releases second quarter production results

19 July 2023

Rio Tinto Chief Executive Jakob Stausholm said: "We built further momentum in our Pilbara iron ore business for the quarter, and now expect to deliver shipments in the upper half of our guidance range for the year. The ramp-up of the Oyu Tolgoi underground mine progressed ahead of plan, and we remain on track to more than triple its copper production by the end of the decade. Production downgrades during the quarter highlight that we still have much more to do elsewhere, as we roll out the Safe Production System to create stability and achieve excellence across our global portfolio.

"We continued to take disciplined measures to grow in the materials the world needs for the energy transition, also with investments to expand our low carbon aluminium production and underground copper production at Kennecott.

"We are taking practical steps and making investments to decarbonise, being the first to convert an open pit mine to renewable diesel at our Boron operations, signing a memorandum of understanding with Baowu to explore decarbonisation of the steel value chain and delivering first production from our ground-breaking BlueSmelting demonstration plant at Sorel-Tracy in Quebec in July."

Q2 2023 operational highlights and other key announcements

•     Our all-injury frequency rate of 0.36 was a small increase from the second quarter of 2022 (0.35), and from the prior quarter (0.35). Investigations are underway following significant process safety incidents. There were two incidents at our Rio Tinto Iron and Titanium (RTIT) Sorel-Tracy complex which did not result in injuries. The Kennecott operation experienced an escape of furnace gas during the maintenance shut, where all treated people have been cleared.  We are heightening our focus on managing these risks and continue to prioritise the safety, health and wellbeing of our workforce, and communities where we operate.

•     Pilbara operations produced 81.3 million tonnes (100% basis) in the second quarter, 3% higher than the second quarter of 2022 as Gudai-Darri achieved sustained nameplate capacity during the period. Shipments were 79.1 million tonnes (100% basis), 1% lower than the corresponding period of 2022, reflecting the impact of planned major maintenance at the Dampier port and a train derailment. With continued operational improvements across the Pilbara system, and the implementation of the Safe Production System, full year shipments are now expected to be in the upper half of the original 320 to 335 million tonne range. 

•     Bauxite production of 13.5 million tonnes was 5% lower than the second quarter of 2022 as our Weipa operations were impacted by the higher-than-average first quarter rainfall, which continued to reduce pit access and led to longer haul distances. Production was further affected by equipment downtime at both Weipa and Gove. As a result, our bauxite full year production is expected to be at the lower end of our 54 to 57 million tonne range, as we implement plans to recover lost production at both operations through the remainder of the year.

•     Aluminium production of 0.8 million tonnes was 11% higher than the second quarter of 2022 as we benefited from the continued ramp-up of the Kitimat smelter. Recovery at the Boyne and Kitimat smelters is progressing to plan with full ramp-up expected to be completed later in the year.  All our other smelters continued to demonstrate stable performance during the quarter.

•     On 12 June, we announced an investment of $1.1 billion to expand our AP60 aluminium smelter equipped with low-carbon technology at Complexe Jonquière in Canada. The total investment includes up to $113 million of financial support from the Quebec government. This expansion will coincide with the gradual closure of potrooms at the Arvida smelter on the same site. While at our Alma smelter in Lac-Saint-Jean, Quebec, we commenced construction to increase our capacity to cast low-carbon, high-value aluminium billets.

•     Mined copper production of 145 thousand tonnes (on a consolidated basis), was 1% lower than the second quarter of 2022. We benefited from the continued ramp-up of the high grade underground mine at Oyu Tolgoi. However, this benefit was more than offset by the continued operation of Kennecott's concentrator at reduced rates, as we recovered from a conveyor failure in March 2023, and unplanned maintenance, and lower crusher and conveyor availability, at Escondida.

•     Refined copper guidance has been reduced to 160 to 190 thousand tonnes (previously 180 to 210 thousand tonnes) and our copper C1 unit cost guidance has been raised to 180 to 200 US cents/lb (from 160 to 180 US cents/lb) as completion of the rebuild of the Kennecott smelter is now expected in September 2023 (previously August 2023). The extension of the rebuild is due to the addition of a full rebuild of the flash converting furnace to the scope, which is expected to further improve asset stability and process safety management. 

•     On 20 June, we announced $498 million of funding to deliver underground development and infrastructure for an area known as the North Rim Skarn1 (NRS) at Kennecott. Production from the NRS will commence in 2024 and is expected to ramp up over two years, to deliver ~250 thousand tonnes of additional mined copper over the next 10 years2 alongside open cut operations.

•     Titanium dioxide slag production of 303 thousand tonnes was 4% higher than the second quarter of 2022, due to improved operational performance at our smelters. Notwithstanding, our RTIT Quebec Operations experienced two incidents in separate furnaces in June and July which we are investigating. Given these investigations and weaker market conditions, our full year production is expected to be at the lower end of the 1.1 to 1.4 million tonne range.

•     IOC production was 21% lower than the second quarter of 2022 as we lost ~3.5 weeks of production in June, primarily due to wildfires in Northern Quebec, together with a slightly extended shutdown. Operations have resumed, however our full year production guidance has been reduced to 10.0 to 11.0 million tonnes (previously 10.5 to 11.5 million tonnes), and remains subject to further disruption from fire conditions.

•     At our Rincon lithium project in Argentina, our $140 million estimate and schedule to develop the starter plant remains under review in response to cost escalation.

•     In the second quarter, we commenced deployment of the Safe Production System at a further two sites, taking the total to 20 sites. The Safe Production System focuses on continuously improving safety, strengthening employee engagement and sustainably lifting operational performance across our global portfolio. While we still have a lot to do to see sustainable improvement, site deployments are rolling out according to plan and we expect to be at the upper end of our range of four to eight new sites in 2023.

•     On 13 June, we announced that Ivan Vella, Chief Executive, Aluminium, has accepted a new position outside of Rio Tinto and will leave in December 2023. He will continue to lead Aluminium while a robust process to identify his successor is undertaken but has stepped down from the Group's executive committee.

•     We saw a cash outflow from an increase in working capital of circa $0.9 billion in the first half of 2023, reflecting a build in blasted and mine stocks in the Pilbara to support overall system health, and higher spares and stores (including seasonality due to the Diavik winter road). Payables were also lower due to the timing of spend, and normal volatility in amounts due to JV partners and employees. Operating cash flow was also impacted by lower dividends from Escondida during the first half ($0.3 billion in H1 2023; $0.6 billion in H1 2022).

4Iron Ore Company of Canada continues to be reported at Rio Tinto share.

 

•     Guidance for 2023 alumina production has been reduced to 7.4 to 7.7 million tonnes (previously 7.7 to 8.0 million tonnes), as Queensland Alumina Limited (QAL) implements initiatives to improve plant stability and production rates. 

•     Guidance for 2023 refined copper has been reduced to 160 to 190 thousand tonnes (previously 180 to 210 thousand tonnes) due to the extension of the Kennecott smelter rebuild.

•     Guidance for 2023 IOC production has been reduced to 10.0 to 11.0 million tonnes (previously 10.5 to 11.5 million tonnes) due to the impact of wildfires in Northern Quebec, and remains subject to further disruption from fire conditions.

•     Iron ore shipments and bauxite production guidance remain subject to weather impacts.

Operating costs

•     Guidance for 2023 Pilbara iron ore unit cash costs is unchanged at $21.0 to $22.5 per tonne, based on A$:US$ exchange rate of 0.70.

•     Guidance for 2023 Copper C1 unit costs has been increased to 180 to 200 US cents/lb (from 160 to 180 US cents/lb) due to lower refined copper production following extension of the Kennecott smelter rebuild.

Aluminium modelling

As reported in 2022, to assist with the modelling of aluminium operating costs during a volatile price environment for raw materials, we provide the following breakdown and sensitivities for the alumina and aluminium metal segments (Primary Metal and Pacific Aluminium). This excludes the effect of intra and inter segment eliminations on group profit.

 

We have observed a reduction in index prices for many of the raw material prices for our alumina and aluminium metal segments during the first half of 2023, when compared to the second half of 2022. Despite this, there has been limited impact to our operating costs in the current half given the lag effect associated with the utilisation of higher cost inventory, with the benefit to costs expected in the second half of 2023.

Investments, growth and development projects

•     Exploration and evaluation expense in the first half of 2023 was $710 million, $343 million (94%) higher than the first half of 2022, with continued ramp-up of early works at Simandou (included on a 100% basis1) and in Argentina.

Pilbara mine projects

•     The ramp-up of Gudai-Darri continued to plan with the mine reaching its nameplate capacity on a sustained basis during the second quarter.

•     Construction of our Western Range mine continued in line with the schedule during the quarter with site facilities completed and contractors mobilised, while we progressed bulk earthworks for the fixed plant and pre-strip earthworks for the mine.

•     We continue to progress our next tranche of Pilbara mine projects after Western Range, progressing studies for Hope Downs 1 Sustaining (Hope Downs 2 and Bedded Hilltop), Brockman 4 sustaining (Brockman Syncline 1), Greater Nammuldi Sustaining and West Angelas Sustaining.  We continue to work closely with local communities, Traditional Owners and governments to progress approvals required for the new mining projects.

Oyu Tolgoi underground project

•     In early July, we hosted a site tour of the Oyu Tolgoi operations for investors and analysts. Presentation materials for this visit are available on our website.

•     We continue to see strong performance from the underground mine, with a total of 54 drawbells opened from Panel 0, including 18 drawbells during the quarter. To date we are yet to lose a drawbell or draw point from the underground mine.

•     Shaft sinking rates improved during the quarter and at the end of June, shafts 3 and 4 reached 627 metres and 740 metres below ground level, respectively. Final depths required for shafts 3 and 4 are 1,148 and 1,149 metres below ground level, respectively. As reported in our presentation materials for the Oyu Tolgoi site tour, we now expect both shafts to be commissioned in the second half of 2024 (previously first half of 2024) with shaft sinking rates now meeting those required for completion.

•     Construction of conveyor to surface works continued to plan and are now approaching 60% completion as at the end of the quarter. Construction works for the concentrator conversion also progressed during the period, with the main contractor mobilised and the commencement of major site works in May.

•     Technical studies for mine design and schedule optimisation for Panels 1 and 2 were completed during the second quarter2. The operation is expected to ramp up to deliver average mined copper production of ~500ktpa (100% basis) between 2028 and 20363.

•     During the quarter, Rio Tinto, Oyu Tolgoi and the Government of Mongolia continued to work together towards the implementation of Mongolian Parliamentary Resolution 103.

Other key projects and exploration and evaluation

•     At Complexe Jonquière in Canada, we announced an investment of $1.1 billion to expand our AP60 aluminium smelter equipped with low-carbon technology. The total investment includes up to $113 million of financial support from the Quebec government. This expansion will coincide with the gradual closure of potrooms at the Arvida smelter on the same site. The investment will add 96 new AP60 pots, increasing capacity by approximately 160,000 metric tonnes of primary aluminium per year. As a result, there will be a total of 134 AP60 pots and a capacity of approximately 220,000 tonnes per annum. This new capacity, in addition to 30,000 tonnes of new recycling capacity at Arvida expected to open in the first quarter of 2025, will offset the 170,000 tonnes of capacity lost through the gradual closure of potrooms at the Arvida smelter from 2024.

•     At our Alma smelter in Lac-Saint-Jean, Quebec, we commenced construction to increase our capacity to cast low-carbon, high-value aluminium billets by 202,000 metric tonnes. The existing casting centre will be expanded to include new state-of-the-art equipment such as furnaces, a casting pit, coolers, handling, inspection, sawing and packaging systems. Commissioning is scheduled for the first half of 2025. The $188 million investment will allow more of Rio Tinto's aluminium production to be used to make billets from renewable hydroelectric power.

•     At Kennecott, we announced $498 million of funding to deliver underground development and infrastructure for an area known as the North Rim Skarn4 (NRS). Production from the NRS will commence in 2024 and is expected to ramp up over two years, to deliver around 250 thousand tonnes of additional mined copper over the next 10 years5 alongside open cut operations.

•     At the Resolution Copper project in Arizona, the United States Forest Service (USFS) continued work to progress the Final Environmental Impact Statement (FEIS) and complete actions necessary for the land exchange. We continued to advance partnership discussions with several federally-recognised Native American Tribes who are part of the formal consultation process. We are also monitoring the Apache Stronghold versus USFS case held in the US Ninth Circuit Court of Appeals. While there is significant local support for the project, we respect the views of groups who oppose it and will continue our efforts to address and mitigate these concerns. Costs attributable to the Resolution project in the first half of 2023 were $68 million6.

•     At the Winu copper-gold project in Western Australia, we continued to strengthen our relationships and advanced agreement making over the quarter with host Traditional Owners, the Martu and Nyangumarta groups. Drilling, fieldwork and study activities continued over the period strengthening the development pathway ahead of applications for regulatory and other required approvals. Costs attributable to the Winu project in the first half of 2023 were $32 million6.

•     At the Simandou iron ore project in Guinea, negotiations continued to progress to enable the co-development of rail and port infrastructure by Simfer, Winning Consortium Simandou and the Guinean State. The legal framework for the construction and operations phases will establish access rights, fiscal regime and schedule, as well as joint venture arrangements. We also continued to progress early works, including establishing accommodation camps to support continued mobilisation on both our mine and rail scope, earthworks and geotechnical drilling. Costs attributable to the Simandou project in the first half of 2023 were $318 million (100% basis)6. Management responsibility for Simandou transferred from the Copper product group to the Chief Technical Officer during the period, with the exploration and evaluation expense now shown separately in Other operations.

•     NutonTM, our proprietary copper heap leaching technology, made further progress during the quarter, with associated results reported by Arizona Sonoran Copper Company on 5 June, McEwen Mining Inc. on 20 June and Regulus Resources Inc. on 6 July.

•     We continue to believe that the Jadar lithium-borate project in Serbia has the potential to be a world-class asset, that will support the development of other future industries in Serbia, acting as a catalyst for tens of thousands of jobs for current and future generations, and sustainably producing materials critical to the energy transition. We are focused on consultation with all stakeholders to explore options related to the project's future.

•     At the Rincon lithium project in Argentina, development of the three thousand tonne per annum lithium carbonate starter plant is ongoing. Construction activities progressed on the camp and airstrip for the project, while enabling works for the process plant continued. Our $140 million estimate and schedule to develop the starter plant remains under review in response to cost escalation. Studies for the full scale operation are ongoing, and the exploration campaign progressed to further understand Rincon's basin, brine and water reservoirs. We continue to engage with communities, the province of Salta and the Government of Argentina to ensure an open and transparent dialogue with stakeholders about the works underway.

•     Costs attributable to Battery Materials in the first half of 2023 were $112 million6.

Sustainability highlights

We are creating an open and transparent environment which will make positive and lasting change and strengthen our workplace culture for the long term, as we continue to implement the 26 recommendations of the Everyday Respect report. We continue to promote respectful transparency by expanding the adoption of purple banner communications to other parts of the business to highlight disrespectful, discriminatory and hurtful behaviours occurring in our organisation, in the same way we highlight safety concerns. Village councils are being implemented across sites to provide a safe and constructive way for employees and contractors to raise concerns and give feedback. In addition, over 950 people responded to our Pilbara Iron Ore's contractor survey, which was designed to better understand their experiences.

On 3 April, we published our 2022 Taxes and Royalties Paid Report, detailing $10.8 billion of global taxes and royalties paid during the year. This compares to $13.3 billion in 2021, during very strong commodity prices, and is the third-highest annual global taxes and royalties paid by Rio Tinto since it published its first annual Taxes Paid report, for 2010. In the past ten years, Rio Tinto has paid $74.9 billion in taxes and royalties globally, of which more than 78% was paid in Australia.

On 4 April, we announced our support for Energy Resources of Australia Ltd's (ERA) plans for an Interim Entitlement Offer (IEO), which sought to raise up to A$369 million to address funding requirements for the Ranger Rehabilitation Project in Australia's Northern Territory to the end of the second quarter of 2024. Rio Tinto, which owns 86.3% of ERA's shares, subscribed for its full entitlements under the terms of the IEO, at a cost of A$319 million. Rio Tinto notes that ERA has, in the IEO offer material, recognised the Mirarr People's opposition to further uranium mining on their land. This was a relevant factor in Rio Tinto's recent decision to no longer report the Jabiluka deposit as a Mineral Resource.

On 2 May, together with BHP, we invited expressions of interest from technology providers, equipment manufacturers, reagent suppliers, startups and research groups across the globe with innovative ideas and technologies to help improve tailings dewatering and management performance. Together we aim to jointly identify a portfolio of tailings management partners with whom they can work to accelerate the development of technologies that could increase water recovery and reduce potential safety risks and environmental footprints associated with tailings storage facilities.

In May, we published our 2022 Statement on Modern Slavery - our seventh statement against UK modern slavery reporting legislation, and our third under Australian legislation. We know that we face a risk of involvement in modern slavery through our value chain, including through our suppliers. And although we are not aware of any recorded modern slavery incidents or complaints in our business during 2022, we are committed to looking for ways to improve.

Communities & Social Performance (CSP)

On 2 June, we announced plans to invest $395 million in a seawater desalination plant in the Pilbara, Western Australia, to support future water supply for the company's coastal operations and communities in the region. The proposed Dampier Seawater Desalination Plant, which remains subject to Commonwealth and State Government approvals, will be located within Rio Tinto's existing iron ore port operations at Parker Point. It will have an initial nominal capacity of four gigalitres annually with the potential for this to increase to eight gigalitres in the future. The project includes construction of a new supply pipeline to connect to the existing water network. Subject to relevant approvals, construction is expected to commence in 2024 with the facility expected to be operational and producing water in 2026.

On 13 June, we announced a partnership with Gemco Rail to bring local iron ore rail car manufacturing and bearing maintenance to the Pilbara region in an industry-first. This partnership will enable Gemco Rail to expand its existing operations to establish the first ever rail ore car manufacturing and maintenance facility in the Pilbara, creating new jobs, increasing spend with local and Indigenous businesses and supporting local economic growth. Rio Tinto expects to invest approximately A$150 million to purchase 100 locally built ore rail cars over six years as well as continued investment in bearing refurbishment over ten years, to support the company's Pilbara operations.

Key highlights from the quarter are outlined above, with further information available on our website

 

Climate change, product stewardship and our value chain

In the second quarter we continued to focus on innovative solutions that have the potential to be scalable across Rio Tinto's global value chains.

•     On 3 April,  Rio Tinto Iron and Titanium (RTIT) started its BlueSmeltingTM demonstration plant at its metallurgical complex in Sorel-Tracy as part of the process to validate the ground-breaking BlueSmeltingTM technology, which aims to decarbonise RTIT's Quebec Operations. We achieved a further milestone subsequent to the end of the quarter in July, delivering first production from the demonstration plant. The BlueSmeltingTM project involves an ilmenite reduction technology that could generate 95% less greenhouse gas emissions than the current reduction process, enabling the production of titanium dioxide, steel and metal powders with a significantly lower carbon footprint. This innovative technology was developed by scientists at Rio Tinto's Critical Minerals and Technology Centre in Sorel-Tracy.

•     On 2 June, our Boron, California operation successfully completed the full transition of its heavy machinery from fossil diesel to renewable diesel, making it the first open pit mine in the world to achieve this milestone. The change to renewable diesel brings an anticipated CO2 equivalent reduction of up to 45,000 tonnes per year, comparable to eliminating the annual emissions of approximately 9,600 cars.

•     On 12 June, we signed a Memorandum of Understanding (MoU) with China Baowu, the world's biggest steelmaker, to explore a range of industry-leading new projects in China and Australia to help decarbonise the steel value chain. Under the MoU, China Baowu and Rio Tinto plan to jointly advance specific decarbonisation projects, demonstrating their commitment to play a leading role in the industry's low-carbon transformation. The projects include:

◦     Research, build and demonstrate a pilot-scale electric melter at one of Baowu's steel mills in China. This will enable low-carbon steel making utilising Direct Reduced Iron (DRI) that has been produced from low and medium grade ores.

◦     Optimise pelletisation technology for Australian ores as a feedstock for low-carbon shaft furnace-based direct reduction.

◦     Expand the development of China Baowu's HyCROF technology which can largely mitigate CO2 emissions from the blast furnace process.

◦     Jointly study opportunities for producing low-carbon iron in Western Australia.

Activity across our global decarbonisation portfolio continues to accelerate, however physical delivery of renewables, diesel replacement and process heat abatement has not progressed as fast as we would like. Delays have arisen due to a range of factors including engineering and construction timelines, securing approvals and the need to carefully integrate our ambitions with the needs of our local communities and stakeholder groups. This particularly challenges our near term objective in 2025 where we have limited time to make adjustments to physical projects.


Our markets

Although commodity prices remain at elevated levels, they declined during the second quarter as global demand slowed. China's economic recovery has fallen short of initial market expectations, as the property market downturn continues to weigh on the economy and consumers remain cautious despite monetary policy easing. Manufacturing data in advanced economies showed a further slowdown and recessionary risks remain.

•     China's reopening recovery started strongly but slowed in the second quarter. Consumption is still improving, while weakness in the export and property sectors is providing a drag to growth. Factory activity has slowed down, as manufacturing PMI contracted. The Chinese government has stepped up monetary easing measures.

•     The US economy is still growing and the labour market remains resilient, but a recession is still likely later this year. Past tightening of monetary policy and tighter lending standards are expected to constrain consumer spending, hiring and business investment. Inflation remains a challenge for the Federal Reserve, given pressure in the services sector.

•     The eurozone economy continues to be challenged by weak manufacturing activity and high core inflation, as manufacturing output and new orders fell, while services showed an expansion. Core inflation has been pushed up by services, whilst manufactured goods inflation has tapered down.

•     Iron ore prices declined by 12% over the quarter as China's steel demand recovery encountered persistent headwinds, and steel prices and mill profitability remained compressed. As a result, Chinese steel exports trended up sharply towards 100 million tonne annualised, run-rates last observed in 2016. China's seaborne iron ore imports were also supported by the delayed rebound in scrap availability and challenges to domestic iron ore production. Imports over the quarter declined marginally below their 1.25 billion tonne per annum rate in the first quarter, but trended close to record seasonal levels. Seaborne iron ore supply performed strongly over the quarter, with June shipments from Australia and Brazil estimated at or close to all-time highs.

•     The LME cash aluminium price declined by 10% over the quarter, with the average price of $2,258/t 6% lower than the first quarter of 2023. The price has followed industry operating costs lower, with average smelter costs falling 12% quarter on quarter. Smelter restarts are currently under way in Yunnan, adding supply to a tight global market. Inventories in China are at seven-year lows, and China has continued to import primary aluminium in the first half of the year.

•     The copper LME price fell 8% over the quarter, while the average price was down 5% quarter on quarter to $3.84/lb, as negative macroeconomic headlines related to the slowdown in China's recovery and US debt ceiling gridlock dampened sentiment, moving speculative positions to a net short for the first time since August 2022. The US dollar strengthened over the period as inflationary pressures prevailed. Despite these headwinds, prices were supported by increasing operating costs, exchange inventory tightness and market expectations on China's stimulus.

•     Lithium carbonate spot prices rebounded during the second quarter, driven by higher electric vehicle (EV) sales growth and restocking activities from end-users. Short-term uncertainty remains as the global economy slows and higher interest rates dampen consumer spending, although the automotive market sentiment improved in China on the back of tax incentives for EV's and a potential end to the aggressive price war between Chinese car manufacturers. Longer term, market fundamentals for lithium remain strong, as EV adoption continues to rise on supportive government policies and supply shortfalls requiring further investment.

The consolidated basis sales reported here include Robe River Iron Associates on a 65% basis to enable comparison with revenue reported in the financial statements. 

Pilbara operations

We produced 81.3 million tonnes (Rio Tinto share 68.6 million tonnes) in the second quarter, 3% higher than the corresponding period of 2022. The ramp-up of Gudai-Darri continued to plan, with the mine reaching nameplate capacity on a sustained basis during the period. Challenges at the Yandicoogina mine associated with materials handling and plant reliability, highlighted in the first quarter, continued into the period.

Shipments of 79.1 million tonnes (Rio Tinto share 66.6 million tonnes) were 1% lower than the second quarter of 2022, and 4% lower than the prior quarter. This was primarily due to planned major maintenance at the Dampier Port and a train derailment on 17 June. The rail line was reopened on 21 June.

With ongoing operational improvements across the Pilbara system, and uplift from implementation of the Safe Production System, full year shipments are expected to be in the upper half of the original 320 to 335 million tonne range. With higher production anticipated in the second half, SP10 is expected to be a larger proportion of shipments (first half 2023 = 10%1).

Approximately 10% of sales in the second quarter were priced by reference to the prior quarter's average index lagged by one month. The remainder was sold either on current quarter average, current month average, average of two months, forward month or on the spot market. Approximately 26% of sales in the second quarter were made on a free on board (FOB) basis, with the remainder sold including freight.

Achieved average pricing in the first half of 2023 was $98.6 per wet metric tonne ($110.9 in the first half of 2022) on an FOB basis (equivalent to $107.2 per dry metric tonne, with a 8% moisture assumption). This compares to the average first half price for the monthly average Platts index for 62% iron fines converted to an FOB basis of $109.8 per dry metric tonne.

 

China Portside Trading

We continue to see strong demand for Rio Tinto's portside product in China. Our iron ore portside sales in China were 11.9 million tonnes in the first half of 2023 (14.2 million tonnes in the first half of 2022). At 30 June, inventory levels were 5.7 million tonnes, including 2.6 million tonnes of Pilbara product. In the first half of 2023 approximately 90% of our portside sales were either screened or blended in Chinese ports.

Bauxite

Bauxite production of 13.5 million tonnes was 5% lower than the second quarter of 2022 as our Weipa operations were impacted by the higher-than-average first quarter rainfall, which continued to reduce pit access and led to longer haul distances. Production was further affected by equipment downtime at both Weipa and Gove. As a result, our bauxite full year production is expected to be at the lower end of our 54 to 57 million tonne range, as we implement plans to recover lost production at both operations through the remainder of the year.

We shipped 9.2 million tonnes of bauxite to third parties in the second quarter, 5% lower than the same period of 2022.

Alumina

Alumina production of 1.9 million tonnes was in line with the second quarter of 2022 as improved operational stability at our Yarwun and Vaudreuil refineries was offset by unplanned plant downtime at Queensland Alumina Limited (QAL). As a result, our full year alumina production has been reduced to 7.4 to 7.7 million tonnes (previously 7.7 to 8.0 million tonnes), as QAL implements initiatives to improve plant stability and production rates. 

As the result of QAL activation of a step-in process following sanction measures by the Australian Government, Rio Tinto has taken on 100% of capacity for as long as the step-in continues. This results in use of Rusal's 20% share of capacity by Rio Tinto under the tolling arrangement with QAL. This additional output is excluded from the production tables in this report as QAL remains 80% owned by Rio Tinto and 20% owned by Rusal.

Aluminium

Aluminium production of 0.8 million tonnes was 11% higher than the second quarter of 2022 as we benefited from the continued ramp-up of the Kitimat smelter. Recovery at the Boyne and Kitimat smelters is progressing to plan with full ramp-up expected to be completed later in the year.  All our other smelters continued to demonstrate stable performance during the quarter.

Average realised aluminium prices including premiums for value-added products (VAP) decreased 25% to $2,866 per tonne in the first half of 2023 (first half 2022: $3,808 per tonne). The LME price decreased by 24% to $2,329 per tonne (first half 2022: $3,082 per tonne), whilst the mid-west premium duty paid declined 27% to $583 per tonne in the first half of 2023 (first half 2022: $801 per tonne), which is 56% of our total volumes (58% in the first half of 2022). Our VAP sales decreased to 47% of primary metal sold in the first half of 2023 (first half 2022: 52%). Product premiums for VAP sales decreased, averaging $377 per tonne of VAP sold (first half 2022: $422 per tonne).

2Includes Oyu Tolgoi on a 100% consolidated basis, Kennecott and Escondida on an equity share basis.

Kennecott

Mined copper production was 27% lower than the second quarter of 2022 as the concentrator continued to recover from the failure of a conveyor in March 2023. Mitigating activities have progressed in line with recovery plans, with the conveyor now performing at rates to enable the concentrator to return to full capacity in the third quarter of 2023. The majority of the winter snowpack melted during the quarter, with the successful implementation of a range of measures to manage the associated geotechnical risk resulting in minimal impact to operations.

Refined copper production was 56% lower than the second quarter of 2022 as we commenced the largest rebuild of the smelter and refinery in Kennecott's history in May 2023. The ~$300 million rebuild has incorporated approximately 300 engineering and maintenance projects and we are on track to complete the full scope of work. While inspecting the integrity of the flash converting furnace, we identified additional work necessitating a full rebuild, rather than the planned partial rebuild. The full rebuild is expected to further improve asset stability and process safety management, however as a result the consolidated scope of work is now expected to be completed in September 2023 (previously August 2023).

As a consequence of this extension, our refined copper production guidance has been reduced to 160 to 190 thousand tonnes (previously 180 to 210 thousand tonnes) and our copper C1 unit cost guidance has been increased to 180 to 200 US cents/lb (from 160 to 180 US cents/lb).

Escondida

Mined copper production was 6% lower than the second quarter of 2022 due to 10% lower concentrator throughput rates following unplanned maintenance, and lower crusher and conveyor availability. In addition, there was also a 16% decrease in copper recoverable from ore stacked for leaching due to lower grades and  volume of stacked material.

Refined production increased by 30% compared to the second quarter of 2022 due to improved ore qualities in the oxide leach and better sulphide leach performance on the run of mine pad.

On 17 May 2023, the Chamber of Deputies of Chile approved a new mining royalty which will impact Escondida through a 1% ad-valorem component and an increased operating margin component, all limited by a maximum overall tax rate of 46.5%. The new mining royalty will be effective as of 1 January 2024.

 

Oyu Tolgoi

Mined copper production on a 100% basis increased 40% from the second quarter of 2022 as the ramp-up in underground production continued to plan, delivering higher average copper head grades (0.52% vs. 0.40%). During the quarter we delivered 0.9 million tonnes of ore milled from the underground mine at an average copper head grade of 1.56%, and 8.8 million tonnes from the open pit with an average grade of 0.41%.

Following our acquisition of Turquoise Hill Resources Ltd on 16 December 2022, our equity share of production increased from 33.52% to 66%, effective in reporting from 1 January 2023. We continue to fully consolidate Oyu Tolgoi in our financials.

During the quarter we signed an extension with the Inner Mongolian Power Company, securing our power supply for the operation until 2030.

NutonTM

NutonTM, our proprietary copper heap leaching technology, made further progress during the quarter, with associated results reported by Arizona Sonoran Copper Company on 5 June, McEwen Mining Inc. on

Iron Ore Company of Canada (IOC)

Iron ore production was 21% lower than the second quarter of 2022, as we lost ~3.5 weeks of production in June, primarily due to wildfires in Northern Quebec, together with a slightly extended shutdown. Operations have resumed, however our full year production guidance has been reduced to 10.0 to 11.0 million tonnes (previously 10.5 to 11.5 million tonnes), and remains subject to further disruption from fire conditions.

Shipments were 1% higher than the second quarter of 2022, as we drew down inventory. Although logistics have resumed following the wildfires, loading restrictions at the rail and port remain a risk as we repair areas of the rail line damaged by fire. 

Borates

Borates production in the second quarter was 3% lower than the corresponding period of 2022 due to the deferral of a bulk vessel to the next quarter. We continued to see an easing of supply chain constraints at the Port of Los Angeles in the period.

Iron and Titanium

Titanium dioxide slag production was 4% higher than the second quarter of 2022, due to improved operational performance at our smelters. Notwithstanding, our RTIT Quebec Operations experienced two incidents in separate furnaces in June and July which we are currently investigating. Given these investigations and weaker market conditions, our full year production is expected to be at the lower end of our 1.1 to 1.4 million tonne range.

Diamonds

At Diavik, our share of carats was 16% lower than the second quarter of 2022 due to the completion of an underground pipe and area of the open pit during the period.

 

 

 

 


Exploration and evaluation

Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the profit and loss account in the first half of 2023 was $710 million, compared with $367 million in the first half of 2022. Approximately 45% of this expenditure was incurred for Simandou, 18% by central exploration, 17% by Minerals, 15% by Copper and 4% by Iron Ore. The increase in expenditure reflects the continued ramp-up of early works at Simandou (included on a 100% basis1) and Argentina.

Our annual budget for central greenfield exploration remains around $250 million, mainly focused on copper, with a growing battery minerals programme.

Exploration highlights

Rio Tinto has a strong portfolio of projects with activity in 18 countries across eight commodities in early exploration and studies stages. The bulk of the exploration expenditure in the second quarter focused on copper in Australia, Colombia, Chile, Zambia, Peru, the US and Kazakhstan, and diamonds in Angola.
Rio Tinto recently partnered in two lithium exploration projects in Quebec and greenfield lithium exploration continues in Canada, Australia, US and Africa. Exploration for nickel is ongoing in Canada, Finland, Brazil and Peru. Mine-lease exploration continued at Rio Tinto managed businesses including Bingham Canyon in the US, Pilbara Iron Ore in Australia and Diavik in Canada.

(b) On 16 December 2022, Rio Tinto completed the acquisition of 100% of Turquoise Hill Resources Ltd, increasing our ownership in Oyu Tolgoi from 33.52% to 66%. From 1 January 2023, our share of production has been updated to reflect this change.

(c) We continue to process third party concentrate to optimise smelter utilisation. There was no cathode produced from purchased concentrate in 2023 year-to-date. Purchased and tolled copper concentrates are excluded from reported production figures and production guidance. Sales of cathodes produced from purchased concentrate are included in reported revenues.

(a) Mine production figures for metals refer to the total quantity of metal produced in concentrates, leach liquor or doré bullion irrespective of whether these products are then refined onsite, except for the data for bauxite and iron ore which represent production of marketable quantities of ore plus concentrates and pellets.

(b) Includes 100% of production from Paraburdoo, Mt Tom Price, Western Turner Syncline, Marandoo, Yandicoogina, Brockman, Nammuldi, Silvergrass, Channar, Gudai-Darri and the Eastern Range mines. Whilst Rio Tinto owns 54% of the Eastern Range mine, under the terms of the joint venture agreement, Hamersley Iron manages the operation and is obliged to purchase all mine production from the joint venture and therefore all of the production is included in Rio Tinto's share of production.

(c) SP10 includes other lower grade products.

(d) Shipments includes material shipped to our portside trading facility in China which may not be sold onwards in the same period.

(e) Represents the difference between amounts shipped to portside trading and onward sales from portside trading, and third party volumes sold.

(f) While Rio Tinto has a 53% net beneficial interest in Robe River Iron Associates, it recognises 65% of the assets, liabilities, sales revenues and expenses in its accounts (as 30% is held through a 60% owned subsidiary and 35% is held through a 100% owned subsidiary). The consolidated basis sales reported here include Robe River Iron Associates on a 65% basis to enable comparison with revenue reported in the financial statements.

(a) Includes 100% of production from Paraburdoo, Mt Tom Price, Western Turner Syncline, Marandoo, Yandicoogina, Brockman, Nammuldi, Silvergrass, Channar, Gudai-Darri and the Eastern Range mines. Whilst Rio Tinto owns 54% of the Eastern Range mine, under the terms of the joint venture agreement, Hamersley Iron manages the operation and is obliged to purchase all mine production from the joint venture and therefore all of the production is included in Rio Tinto's share of production.

(b) SP10 includes other lower grade products.

(c) Shipments includes material shipped to our portside trading facility in China which may not be sold onwards in the same period.

(d) Include Pilbara and IOC sales adjusted for portside trading movements and third party volumes sold.
