Rio Tinto releases second quarter 2026 production results

15 July 2026

Driving performance to achieve 3% YoY CuEq¹ growth in the first half

Rio Tinto Chief Executive Simon Trott said: "We are delivering growth as we drive performance across the group, with copper equivalent production up 3 per cent in the first half.

"Our scale, geographical diversification and sophisticated supply chains continue to underpin our resilience and strong operational performance despite ongoing geopolitical uncertainty throughout the period.

"In the Pilbara, we achieved our highest first half iron ore production since we set a record in 2018, through the successful implementation of our ongoing productivity improvement program. In copper, Oyu Tolgoi continued to ramp up on schedule to deliver more than 30 per cent growth for the first half, while our integrated, large-scale aluminium business sustained its strong performance.

"At Simandou, we continue to advance at pace. SimFer mine construction and port infrastructure are both now more than three quarters complete, with full rail commissioning achieved in the first quarter. We are progressing our next generation of copper growth options at Resolution and Winu, while in lithium we achieved first production ahead of plan at Sal de Vida and Fénix 1B.

"We are driving a step-change in operational performance to deliver industry leading returns and growth for our shareholders."

​

1.  Executive Summary

•     Operational excellence: 3% YoY increase in copper equivalent (CuEq)¹ production for the first half.

•     Copper: Oyu Tolgoi ramp-up remains on track; H1 production delivered 31% YoY growth. Copper C1 net unit cost guidance has been reduced to US 30 - 50c/lb (from US 65 - 75c/lb).

•     Iron ore: Q2 global iron ore sales were 89Mt, up 5% YoY. Q2 Pilbara sales up 7% YoY. SimFer mine construction and port infrastructure now both over three quarters complete.

•     Aluminium: Resilience across the supply chain, with a strong recovery in bauxite.

•     Lithium: Production rose 20% YoY in Q2 driven by the ramp-up at Rincon starter plant and delivery of first tonnes at Sal de Vida and Fénix 1B, ahead of plan.

¹ Copper equivalent (CuEq) volume = Rio Tinto's share of production volume / Volume conversion factor x Product price ($/t) / Copper price ($/t). Prices are based on long-term consensus prices. ² Rio Tinto share unless otherwise stated. ³ Iron Ore production for Pilbara operations and Iron Ore Company of Canada (IOC) refers to saleable production (after crushing, screening and beneficiation). For Simandou, it represents ore ready for train loading at the SimFer mine gate: final (tertiary) crushing of Simandou ore takes place in China. ⁴ Includes all shipments from Pilbara and IOC, including those to our Portside trading business; excludes shipments from our Portside trading business. It also includes Simandou sales, where there is a ~2-3 month lag between mine gate production and sales for railing, shipping to China and tertiary crushing. 2026 sales guidance (100% basis) is 5-10 Mt for Simandou and 15-18 Mt for IOC.          ⁵ Pilbara iron ore guidance remains subject to the timing of approvals for planned mining areas and heritage clearances. ⁶ QAL production now included on a 100% basis. ⁷ Includes primary aluminium only. ⁸ H1 2025 represents production since March following completion of the Arcadium acquisition.  Q1 2025 LCE production was 5.6kt (6.5kt on a 100% basis); LCE shipments were 3.8kt  (5.0kt on a 100% basis). ⁹ Wet metric tonnes. ¹⁰ See further notes in Section 2, 2026 guidance.

2.  Guidance

Production/sales guidance is unchanged¹.

Unit cost guidance:

Pilbara iron ore unit cash costs unchanged.

•     Note: Diesel prices increased from ~$85/bbl to ~$140/bbl during H1, resulting in a ~$0.8/t YoY increase in unit costs in H1. A US$10/bbl increase in diesel price is estimated to impact full year Pilbara unit costs by ~$0.15/t².

Copper C1 net unit costs reduced

•     Guidance range reduced to US 30 - 50c/lb (from US 65 - 75c/lb) due to higher than expected gold prices and productivity improvements.

	2026 Guidance
Pilbara iron ore unit cash costs, free on board (FOB) basis - US$ per wet metric tonne	23.5 - 25.03
Copper C1 net unit costs (Kennecott, Oyu Tolgoi and Escondida) - US cents per lb	30 - 504

¹ Guidance remains subject to weather impacts.

² There will be timing differences between market rates and realised diesel prices due to contractual arrangements.

³ Subject to the impact of higher diesel prices and foreign exchange. Based on Australian dollar exchange rate of 0.67.

⁴ Gold price assumption is $4,026/oz (spot price as at 30 June 2026).

3. Group update 

Expenditure on exploration and evaluation

•     Year to date pre-tax and pre-divestment expenditure on exploration and evaluation charged to the Income Statement was $480 million compared with $334 million in 2025. Approximately 57% of the spend was by the Copper product group, 25% by central exploration and other operations and 18% by the Iron Ore product group.

•     Copper accounts for the majority of total expenditure on exploration and evaluation.

Group financial update

•     In February 2026, Oyu Tolgoi LLC received tax assessments amounting to MNT 1.6 trillion ($443 million) in primary tax, interest and penalties from the Mongolian Tax Authority, pertaining to tax audits covering the financial years 2021 and 2022. As required by Mongolian tax law, Oyu Tolgoi paid this amount in full in March 2026 reserving its rights to dispute the payment. These assessments are inconsistent with the Oyu Tolgoi Investment Agreement and applicable Mongolian legislation, and we are taking relevant steps including engaging in discussions with the Government of Mongolia to resolve this matter¹.

•     In H1 2026, in addition to the $443 million tax payment described above, we saw a cash outflow of ~$1.2 billion from an increase in working capital. Drivers include higher inventories, primarily in iron ore, following the impact of cyclones in Q1 on Pilbara port capacity and the ramp-up of Simandou, together with normal seasonal movements in amounts due to JV partners and employees.

•     We have refined our definition of free cash flow to include Rio Tinto share of capital investment, effective from our H1 2026 financial results. Further detail on this change in methodology is available on our website.

Middle East conflict

Operational impacts to Rio Tinto remain limited, with no material disruption to production or outbound supply chains across our core commodities. Our scale, geographical diversification and trading and procurement capability continue to underpin resilience, enabling supply continuity of raw materials to our operations and products to our customers, despite significant global supply chain dislocation. Prices for our core commodities have remained broadly supportive in Q2, as detailed in our markets section.

Conditions in the Strait of Hormuz remain highly volatile. We continue to monitor developments closely and maintain contingency plans to address potential escalation or further disruption to global energy and logistics markets.

¹ Further information in relation to these assessments can be found in our 2025 Annual Report in notes 10, 15 and 39 to the financial statements and in our 2025 Taxes and Royalties Paid report on page 23.

4. Our markets

Global economy: the economic impacts from the prolonged closure of the Strait of Hormuz have remained moderate to date. Overall, global manufacturing remained in expansion in June, with the global investment goods output Purchasing Managers' Index (PMI) tracking at the strongest quarterly average since 2021, pointing to strong capital investment.

Chinese economy: industrial production slowed to 4.3% in April and May from 6.1% YoY in Q1, partly reflecting lower oil supply entering the industrial production value chains. This has been evident in sequentially weaker output of chemicals and processed petroleum products. Exports continue to surge, reinforcing the theme of soft domestic consumption and strong exports.

US economy: growth has remained resilient, boosted by the ongoing AI-linked capital investment boom, the fading impact of reciprocal tariffs and a positive terms-of-trade effect from higher energy prices.

Copper

•     London Metal Exchange (LME) copper prices reached a record high of $6.39/lb ($14,096/t) in mid-May, supported by optimism around AI-driven electricity demand, strong investor flows and renewed supply disruption concerns. LME prices have since moderated, largely due to a stronger US dollar, but have remained supported around $5.90/lb ($13,000/t).

•     Copper leaching operations in the DRC and Chile are facing disruptions to sulphuric acid supply due to the Middle East conflict. While no cost-related curtailments have been observed, acid shortages have reportedly reduced output at some operations.

•     The US Government has not provided an update regarding possible tariffs on refined copper cathode imports. Chicago Mercantile Exchange (CME) copper prices continue trading above LME prices as a result and the US continue to import more copper cathode than is required to meet demand.

•     The copper concentrate market remained extremely tight in Q2, with spot treatment and refining charges ending the quarter at a record low of -$150/t. High sulphuric acid prices have provided a revenue tailwind to smelters.

Iron ore

•     Iron ore prices remained resilient, increasing by 2% in Q2 to $105/dmt.

•     China's crude steel and pig iron production increased in Q2, on a QoQ basis, but contracted compared to the same period in 2025.

•     Ex‑China Q2 steel production is estimated to have stagnated amid ongoing geopolitical, supply chain and demand-side headwinds.

•     China's net steel exports increased by more than 20% QoQ in Q2 as exporters adapted to the licensing regime introduced on 1 January, lifting to a ~120 Mt annualised run rate.

•     Seaborne iron ore supply was strong in Q2, with fewer seasonal disruptions, lifting shipments by 14 Mt YoY. Supply growth largely came from production increases in West Africa and South America, which offset declines from the Middle East and Canada.

•     Higher energy costs have lifted the global iron ore cost curve, particularly for marginal suppliers with greater exposure to diesel prices.

Aluminium

•     The Middle East conflict has reduced ex-China aluminium supply, with smelter curtailments contributing to an expected global deficit in 2026. As a result, ex-China inventories have trended towards historically low levels.

•     The LME aluminium price reached a four-year high in May, driven by supply curtailments that tightened physical metal availability while demand for value-added products remained steady. Physical market tightness was reflected in higher spot market premiums across the US, Japan and Europe. The price has since eased to around $3,150/t, still well above the 2025 average of $2,632/t. This decline in the price is due to an expected recovery in Middle East supply, though restarts remain at a very early stage, and the path back to full production is uncertain.

•     China bauxite CIF prices remained supported in Q2 on higher seaborne freight costs. However, FOB margins for Guinean producers came under pressure from higher fuel and royalty costs. Guinean bauxite shipments fell in Q2, before improving at the end of the quarter.

•     Australian FOB alumina prices remained range-bound in Q2 amid softer alumina demand and higher output in Indonesia and China. Alumina inventories in China remained elevated through the quarter.

Lithium 

•     Lithium carbonate prices increased by 13% QoQ, supported by supply disruption concerns in Zimbabwe and China and rapidly expanding Battery Energy Storage Systems (BESS) demand.

•     Globally, BESS shipments increased 108% YoY in the first five months of 2026, while Electric Vehicle (EV) sales growth was up 1% YoY, as policy support in China and North America continued to unwind. BESS demand currently accounts for around 30% of lithium demand.

¹ Assumes 8% moisture. Pilbara average realised price excludes the impact of certain joint venture arrangements. Including these, realised prices for H1 2026 would have been $1.1/wmt lower (H1 2025, $0.7/wmt). 

² Average realised price for all units sold. Realised price does not include the impact of provisional pricing adjustments, which positively impacted revenues in H1 2026 by $235 million (H1 2025 positive impact of $266 million). 

³ LME plus all-in premiums (product and market). The US Midwest premium adapted to tariff levels in 2025, fully compensating for the 50% tariff after an initial period. Tariff costs are shown on page 8. 

⁴ Realised lithium carbonate equivalent price is calculated as total lithium revenue divided by total lithium carbonate equivalent (LCE) volume sold, and therefore represents a blended average across products and contracts rather than a spot or index reference. A portion of volumes is sold under longer term customer contracts, with realisations recognised on a lagged basis, so realised prices may not move in line with, or over the same period as, movements in the reference index price. Lithium results are consolidated from the date of acquisition of Arcadium Lithium (March 2025); accordingly, the H1 2025 comparative reflects the post-acquisition period only and excludes January and February 2025.

1 Includes Oyu Tolgoi and Kennecott on a 100% consolidated basis, and Escondida on an equity share basis. 2 We continue to process third party concentrate to optimise smelter utilisation, including 13 thousand tonnes of cathode produced from purchased concentrate in Q2 2026. Purchased and tolled copper concentrates are excluded from reported production figures and guidance. Sales of cathodes produced from purchased concentrate are included in reported revenues.

Kennecott

•     Q2 / YoY: lower cathode production primarily due to reduced availability of high quality copper concentrate. Ore treated was lower due to mine sequencing adjustments associated with geotechnical management, planned concentrator maintenance in June of 23 days (now complete) and a 3 day safety stand-down in April, following the fatality in Q1, that halted production across the value-chain.

•     Mine resequencing following preventative geotechnical management activities is nearing completion and is expected to restore full access to planned mining areas during H2 2026. An additional 12 haul trucks have also been returned to service to support higher mining rates and improved production performance.

•     A flash converting furnace breach in June 2026 resulted in an unplanned outage at the smelter. There were no adverse safety or environmental impacts from the breach. A full rebuild is estimated to take approximately 75 days, from the incident in late June, which will reduce refined copper and gold production in H2 2026. The flash smelting furnace at the smelter will continue to operate, producing matte, a marketable intermediate copper product. Including the copper contained in matte, total copper production estimates are unchanged for the year. Unsold matte will be converted into cathode and contribute to cash flows in 2027. Mining and concentrator operations will continue, with no impact to mined copper production.

Escondida

•     Q2: refined copper production increased primarily due to improved Full Sal¹ production.

•     YoY: concentrate production declined driven mainly by expected lower ore grades from the mine sequence. Refined production increased due to improved performance in both Full Sal and sulphide leaching.

Oyu Tolgoi

•     Q2: planned maintenance at the concentrator impacted production, which was partly offset by higher grades from the underground. The planned maintenance was completed successfully during Q2.

•     YoY: increase in production driven by the ramp up of underground operations, and a higher combined grade from the open pit and underground.

•     In June 2026, the Government of Mongolia agreed to commence work on resolution of the Entrée licence transfer for Panel 1. As this remains in progress, we continue to advance Panels 0 and 2 North followed by Panel 2 South. Panel 1 is expected to be the final panel brought into production. Mine plan options will continue to be assessed and optimised as appropriate.

•     Production ramp-up remains on track to reach an average of around 500 thousand tonnes of copper per year (100% basis and stated as recoverable metal) from 2028 to 2036², inclusive of ongoing sustaining capital expenditure associated with ramp-up activities.

¹  Full SaL is a processing technology that allows the extraction of copper using chloride-assisted leaching predominantly for secondary sulphide material. ² The ~500 thousand tonnes per annum copper production target (stated as recoverable metal) for the Oyu Tolgoi underground and open pit mines for the years 2028 to 2036 was previously reported in a release to the ASX dated 11 July 2023 "Investor site visit to Oyu Tolgoi copper mine, Mongolia". All material assumptions underpinning that production target and those production profiles continue to apply and have not materially changed.

Production figures are sometimes more precise than the rounded numbers shown, hence small rounding differences may appear.

¹ SP10 includes other lower grade products.

² Sales includes material shipped from the Pilbara to our portside trading facility in China which may not be sold onwards by the group in the same period.

³ 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. 

•     Q2 production: stable YoY, supported by improved mine performance following the successful implementation of productivity initiatives targeting equipment and plant operating time.

•     Q2 sales: up 7% YoY and the highest since 2020 supported by strong system performance and healthy stock levels. SP10 represented 8% of total sales in Q2.

◦     Port outload capacity will reduce to below 360 Mtpa during some quarters in H2 2026, 2027 and 2028 with several scheduled major capital projects underway (including Parker Point reclaimers) to improve system flexibility and prepare for Rhodes Ridge.

•     Achieved average pricing¹ in H1 2026 was $85.2 per wet metric tonne ($83.2 in H1 2025) on an FOB basis (equivalent to $92.6 per dry metric tonne, with an 8% moisture assumption).

◦     This compares to the average H1 Platts 61% iron index price for iron ore fines of $92.0 per dry metric tonne, converted to an FOB basis.

•     Q2 sales: 10% of sales priced by reference to the prior quarter's average index lagged by one month:

◦     Remainder sold either on current quarter average, month average or on the spot market.

◦     27% of sales were made on a free on board (FOB) basis, with remainder sold including freight.

•     Q2 portside sales in China: 2.9 Mt (7.8 Mt in Q2 2025)

◦     89% of our portside sales were either screened or blended in Chinese ports.

◦     End-June inventory levels at portside were 6.1 Mt, including 3.4 Mt of Pilbara product.

¹ Pilbara average realised price excludes the impact of certain joint venture arrangements. Including these, realised prices for H1 2026 would have been $1.1/wmt lower (H1 2025, $0.7/wmt).

¹ Sales includes material shipped from IOC to our portside trading facility in China which may not be sold onwards by the group in the same period.

•     Q2 production: multi-year program targeting pit and asset health is in implementation, which, for example, improved total material movement by 14% QoQ.

•     Q2 sales: reduced QoQ due to lower concentrator feed and the ore dumper replacement project, which reduced train unloading capacity into the port.

•     The full year guidance (15-18 Mt) remains subject to the impact of recent forest fires in Canada. We continue to monitor and evaluate the evolving situation.

Simandou

¹ Simandou production represents ore ready for train loading at the SimFer mine gate.

² 2.3 Mt (100% SimFer) of crushed iron ore (1 Mt, Rio Tinto share) was produced in 2025 and was recorded for the first time in Q4 2025, some of which required reprocessing in 2026.

³ There is a ~2-3 month lag between mine gate production and sales for railing, shipping to China and tertiary crushing.

•     Q2 production: increased QoQ following the Q1 tragic fatality, with a conservative, phased restart to operations to ensure disciplined application of safety learnings. Production has also been impacted by the reliability of temporary screening and crushing facilities. Delivery of permanent crushing facilities, expected in H2, will support the ramp-up.

•     Stockpiles: at end of June, 7.6 Mt of uncrushed ore at the mine, which contributes to 9.6 Mt across the entire system, including Guinea port, on ships and in China ports.

•     Q2 sales: 1.6 Mt (100%) shipped to China during the quarter (H1: 2.2 Mt). The first customer collections were completed in April following tertiary crushing in China, with Q2 sales totalling 0.4 Mt (100%) and achieved Fe at 65.8%.

7. Aluminium & Lithium

1  Sangaredi's third-party bauxite shipments for 2025 and Q1 2026 were restated following a reclassification between internal and third-party shipments. Internal shipments are now reported on a 100% basis, with Rio Tinto's share at 45% in line with the offtake arrangement. This has no impact on total bauxite shipments. A 3% humidity adjustment has also now been incorporated. 2 As stated in our Q1 2026 report, we have included QAL on a 100% basis from 2026.

Bauxite

•      Q2: production recovered from Q1 weather disruption, led by Weipa maximising plant operating time and rate, and Gove achieving higher effective plant utilisation. We expect around half of the 0.9 Mt lost from the Q1 cyclone to be recovered throughout the year, supported by, for example, additional haul capacity at Weipa.

Alumina

•      Q2: production reduced QoQ driven by lower output at Yarwun and Vaudreuil following reliability events at both refineries.

•     Note for Yarwun: as announced in November 2025, production is set to reduce by 40% starting from October 2026 (~1.2 Mt impact per year). This change, due to tailings constraints, extends Yarwun's life to 2035.

Aluminium

•     Q2: production increased marginally QoQ with Kitimat, NZAS and AP60 continuing their ramp-up, while the Arvida smelter closed as planned.

◦     Kitimat: ramping up to nameplate capacity with higher water reservoir levels supporting improved hydro power output.

◦     NZAS: at full capacity rates.

◦     Arvida: final two potlines closed in June 2026 as per plan, completing the transition to AP60, which continues to ramp up (as detailed on page 13).

Tariffs

•     Q2: All produced metal was shipped, with sales pricing, product mix and shipping destinations flexed to optimise outcomes in a changing market environment.

	H1 2025	H2 2025	H1 2026
Total RTA shipments - US destination, kt1	723	630	585
Total RTA tariff cost, $m	321	709	773
Average mid-west premium duty paid2, $/tonne	855	1,731	2,406
Average realised tariff costs - US destination, $/tonne	444	1,126	1,322
1 Including both tariff impacted and exempt products. 2 Mid-west premium duty paid applies to approximately 40% of our total volumes.

Recycled aluminium

•     Q2: higher QoQ production was supported by our productivity program across the business. The -5% YoY movement was driven by the closure of the Canton, Ohio facility in mid 2025 to optimise the portfolio. Recycled volumes continue to reflect the reshaped downstream operating footprint in place since Q2 2025.

Aluminium modelling

•     To assist with 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).

Total lithium carbonate equivalent (LCE) production1,2	14.6	+20    %	+15    %	27.3	17.8	+53    %
1 The lithium value chain is vertically integrated and as a result production volumes are not additive. Lithium Carbonate Equivalent (LCE) is derived from volumes of lithium carbonate, lithium chloride, and spodumene concentrate. These compounds are used as feedstock in downstream production. 2 H1 2025 represents production since March following completion of the Arcadium acquisition. Q1 2025 LCE production was 5.6kt (6.5kt on a 100% basis); LCE shipments were 3.8kt (5.0kt on a 100% basis).

•     Q2: strong performance. 

◦     Fénix 1B: first production in Q2, ahead of plan.

◦     Sal de Vida: first production in Q2 ahead of plan, commissioning on track.

◦     Rincón starter plant: continued to ramp up, delivering 385t in Q2, as we focused on reactor stability.

•     YTD: down by 7% YoY primarily reflecting that Mt Cattlin was in operation in Q1 2025 (in care and maintenance since end of March 2025).

Lithium modelling

•     To assist with modelling of lithium operating costs, we are providing the following breakdown and sensitivities for our lithium carbonate and hydroxide processing (covering downstream conversion to hydroxide). This excludes the effect of intra and inter segment eliminations on group profit.

Upstream lithium carbonate & chloride¹

Production cash cost (%)	FY 25	H1 26
Reagents (soda ash, lime)	42	35
Conversion (labour, maintenance, contractors)	29	35
Brine extraction & evaporation (DLE, pumping, ponds)	19	16
Energy (gas, diesel, power)	10	12
Other materials & consumables	1	2
Total	100	100

Downstream lithium hydroxide

Production cash cost (%)	FY 25	H1 26
Lithium carbonate feedstock2	64	69
Conversion (labour, maintenance, contractors)	31	26
Energy, reagents and other materials & consumables	5	5
Total3	100	100

¹ Upstream cost % include assets in production ramp-up during the period (Sal de Vida, Rincon and Fénix 1B), and are yet to be representative of steady-state operating costs. ² Downstream cost % reflects the total internal cost of the lithium carbonate feedstock consumed, consistent with the vertically integrated nature of the value chain. ³ Certain lithium input costs flow through the income statement on a lag as material moves through inventory - typically three months, longer in some cases - so movements in input prices may not be fully reflected in the period in which they occur.

8. Borates and TiO₂

Rio Tinto share of production ('000 tonnes)	Q2 2026	vs Q2 2025	vs Q1 2026	H1 2026	vs H1 2025

Throughout this report, figures in italics indicate adjustments made since the figure was previously quoted on the equivalent page or reported for the first time. Production figures are sometimes more precise than the rounded numbers shown, hence small differences may result between the total of the quarter figures and the year to date figures.
(a) Iron Ore production for Pilbara operations and Iron Ore Company of Canada refers to saleable production (after crushing, screening and beneficiation). For Simandou, it represents ore ready for train loading at the SimFer mine gate: final (tertiary) crushing of Simandou ore takes place in China. There is a ~2-3 month lag between mine gate production and sales for railing, shipping to China and tertiary crushing.

(b) H1 2025 represents production since March following completion of the Arcadium acquisition. Q1 2025 LCE production was 5.6kt  (6.5kt on a 100% basis);  LCE shipments were 3.8kt  (5.0kt on a 100% basis).

(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. Iron Ore production for Pilbara operations and Iron Ore Company of Canada refers to saleable production (after crushing, screening and beneficiation). For Simandou, it represents ore ready for train loading at the SimFer mine gate: final (tertiary) crushing of Simandou ore takes place in China There is a ~2-3 month lag between mine gate production and sales; this accounts for time for railing of ore to the port in Guinea, shipping to China and tertiary crushing in China.

(b) Includes 100% of production from Paraburdoo, Mt Tom Price, Western Turner Syncline, Marandoo, Yandicoogina, Brockman, Nammuldi, Silvergrass, Channar, Gudai-Darri,  Eastern Range and  Western Range mines. Whilst Rio Tinto owns 54% of the Eastern Range and the Western Range mines, 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) Sales includes material shipped to our portside trading facility in China which may not be sold onwards in the same period.

(e) 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.  

(f) Simandou production represents ore at the SimFer mine gate before train loading. Final crushing is undertaken in China, hence, Simandou mine gate production is not considered to be saleable production.

(g) Represents the Rio Tinto equity share of SimFer Jersey (53% owned by Rio Tinto), which owns 85% of the SimFer mine (Blocks 3&4).

(h) There is a ~2-3 month lag between mine gate production and sales for railing, shipping to China and tertiary crushing.

(a) Includes 100% of production from Paraburdoo, Mt Tom Price, Western Turner Syncline, Marandoo, Yandicoogina, Brockman, Nammuldi, Silvergrass, Channar, Gudai-Darri,  Eastern Range and Western Range mines. Whilst Rio Tinto owns 54% of the Eastern Range and the Western Range mines, 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) Sales includes material shipped to our portside trading facility in China which may not be sold onwards in the same period.

(d) Simandou production represents crushed ore at the SimFer mine gate before train loading. Final crushing is undertaken in China, hence, Simandou mine gate production is not considered to be saleable production. There is 7.6Mt (100% SimFer) stockpiled uncrushed ore at the Simfer mine.

(e) Represents Rio Tinto's equity share of SimFer Jersey (53% owned by Rio Tinto), which owns 85% of the SimFer mine (Blocks 3&4).

(f) Iron Ore production for Pilbara operations and Iron Ore Company of Canada (IOC) refers to saleable production (after crushing, screening and beneficiation). For Simandou, it represents ore ready for train loading at the SimFer mine gate: final (tertiary) crushing of Simandou ore takes place in China.

(g) Includes all shipments from Pilbara and IOC, including those to our Portside trading business; excludes shipments from our Portside trading business. It also includes Simandou sales, where there is a ~2-3 month lag between mine gate production and sales for railing, shipping to China and tertiary crushing.
