Rio Tinto releases first quarter 2026 production results

21 April 2026

9% YoY CuEq¹ growth from our three value-generating, world-leading businesses

Rio Tinto Chief Executive Simon Trott said: "Safety is the foundation of our business. The tragic loss of two colleagues this year, at Simandou and Kennecott, is a stark reminder that we must ensure everyone goes home safely at the end of every shift.

"Operating excellence drove 9% YoY copper equivalent¹ production growth across our portfolio as the Oyu Tolgoi copper mine continues to ramp up as planned and our integrated aluminium business, again, delivered a strong performance. Our Pilbara iron ore mines performed strongly, while shipments were impacted by two cyclones in the quarter. We achieved the historic land exchange at Resolution Copper, with our project team focused on unlocking the next phase of one of the world's largest untapped copper deposits.

"The unmatchable mix and scale of our portfolio has ensured growth and supply chain resilience against changing operating conditions as we continue to closely monitor the evolving situation in the Middle East. Our stronger, sharper, simpler way of working is enabling us to move at pace to achieve productivity benefits across the business. The first $650m of annualised benefits is now fully implemented, as promised, with substantially more underway."

1.  Executive Summary

•     Operational excellence: 9% YoY increase in copper equivalent (CuEq)¹ production.

•     Copper: Production rose 9% YoY, supported by the continued successful ramp-up of Oyu Tolgoi. Drilling at Resolution is now underway following completion of the land exchange in March.

•     Iron ore: Second highest Q1 Pilbara production since 2018, up 13% YoY, with sales up 2% YoY. Tropical cyclones impacted Pilbara shipments by approximately 8 Mt, with around half expected to be recovered. The first full SimFer shipment of high-grade Simandou product was successfully delivered to China with first sales realised in April.

•     Aluminium: Strength and agility again demonstrated across our integrated value chain, offsetting weather-related disruptions in bauxite.

•     Lithium: Fenix 1B and Sal de Vida achieved mechanical completion as planned, with first production on track for H2 2026.

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 crushed ore at the SimFer mine gate before train loading: 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, representing ore which has been through tertiary crushing in China and collected by the customer. 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, tertiary crushing in China and collection of final product by the customer. 2026 sales guidance (100% basis) is 15-18 Mt for IOC and 5-10 Mt for Simandou. 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 Q1 2025 LCE production from Arcadium was 17.2kt (20.0kt on a 100% basis) of which 5.6kt was produced since completion of the acquisition in March (6.5kt on a 100% basis), lithium carbonate equivalent shipments from Arcadium was 12.1kt (15.2kt on a 100% basis) of which 3.8kt was shipped since completion of the acquisition in March 2025 (5.0kt on a 100% basis). Production from Rincon starter plant is now included in Q1 2026. ⁹ Wet metric tonnes. ¹⁰ See further notes in Section 2, 2026 guidance.

Safety

Safety remains our highest priority. We are sharpening our focus on safety at every level, simplifying and strengthening our standards to concentrate on what matters most, reinforced by discipline in compliance. Central to this is a renewed focus on critical risk management - ensuring that the controls designed to prevent fatalities are clearly understood, consistently applied and personally owned by leaders.

Following the tragic fatalities at Simandou and Kennecott during the quarter, both operations were immediately shut down and progressively restarted once conditions allowed. At the Kennecott underground project, a staged restart commenced from 16 April.

2.  Guidance

Production/sales guidance

•     2026 production/sales guidance is unchanged.¹

Unit cost guidance

•     2026 unit cost guidance is unchanged.

	2026 Guidance
Pilbara iron ore unit cash costs, free on board (FOB) basis - US$ per wet metric tonne	23.5 - 25.02
Australian dollar exchange rate	0.67
Copper C1 net unit costs (Kennecott, Oyu Tolgoi and Escondida) - US cents per lb	65 - 75

3. Group update 

Expenditure on exploration and evaluation

•     Pre-tax and pre-divestment expenditure on exploration and evaluation charged to the Income Statement in Q1 2026 was $180 million which included expenditure associated with the land exchange at Resolution, compared with $141 million in 2025. Approximately 53% of the spend was by Copper product group, 29% by central exploration, 17% by Iron Ore product group and 1% by Aluminium & Lithium product group.

Productivity benefits

•     By March, as planned, we had implemented the initiatives that are contributing $650m of annualised benefits. These include operational improvements, right sizing central functions and a streamlining of organisational expenses and non-operational initiatives. We are now pursuing further significant improvements focused on throughput, operating costs and central costs to deliver additional benefits over the coming years, beyond the $650m already in place.

Middle East conflict

•     To date: on the supply-side, the direct impacts on our operations have been limited, while our commodity prices have responded favourably. Our scale, global reach and sophisticated supply chains provide a resilient foundation and have enabled the business to operate normally.

◦     Global businesses: Aluminium - the strength of our vertically integrated value chain, with our business advantageously positioned across the Americas, Asia Pacific and Europe, has ensured security of supply to our customers. Iron Ore, Copper, Lithium - operations remained largely unaffected, with no material disruption to supply chains.

◦     Diesel: we consume ~1.6bn litres of diesel annually, around two‑thirds in the Pilbara. Despite higher diesel prices steepening the cost curve, our cost position is resilient, underpinned by scale and global supply‑chain leverage.

◦     Other business inputs (such as jet fuel, caustic soda and others): prices rose, however, there was no disruption to our business. On sulphuric acid, we are a net long producer globally via our Kennecott smelter.

•     We continue to monitor the evolving global impact closely and have contingency plans in place. However, we have relatively limited visibility of how the ongoing conflict will affect supply chains in H2.

¹ Guidance remains subject to weather impacts. ² Pilbara iron ore: subject to the impact of higher diesel prices and foreign exchange. From May, each $10/bbl movement in oil prices (including refining margins) is estimated to impact Pilbara unit costs by approximately $0.15/t, subject to exchange rates and broader inflationary pressures arising from higher diesel prices.

4. Our markets

Global economy: whilst there was good momentum in Q1, with US manufacturing activity accelerating and strong Chinese industrial production and exports, the outbreak of conflict in the Middle East has led to some uncertainty. 

Chinese economy: real GDP growth accelerated from 4.5% YoY in Q4 2025 to 5% in Q1 2026, supported by strength in industrial production and exports. China's high reliance on coal and renewables, as well as substantial oil stockpiles, limited the impact of higher global energy prices on the Chinese economy.

US economy: continues to benefit from a major AI capex boom, benefiting demand for future-facing commodities, and supportive fiscal policy. Manufacturing surveys continue to signal firm growth, with the S&P and ISM Manufacturing PMIs over 52 in March.

Iron ore

•     China's Q1 crude steel and pig iron production declined by -1% compared to the prior year. Ex-China, steel output was on a trajectory of gradual recovery (up 1% YoY during January and February), before being disrupted by events in the Middle East.

•     China's steel exports declined by 10% YoY in Q1, in part due to a new licensing regime which came into effect on 1 January. Steel trade-flows began to be redirected due to the Middle East conflict, given the region's significant imports and exports.

•     On seaborne iron ore supply, multiple cyclones disrupted Australian operations while heavy rainfall in Brazil slowed production and shipments. The major producers' aggregate shipments declined by -17% QoQ and were flat YoY.

•     Higher energy costs are resulting in a lifting of the global iron ore cost curve, particularly for higher cost suppliers whose cost base is typically more sensitive to the diesel price.

Copper

•     London Metal Exchange (LME) copper prices climbed to a record high of $6.28/lb in late January supported by a weaker US dollar, positive sentiment around AI-driven electricity demand and market expectations of limited supply growth in 2026.

•     LME copper retreated to $5.52/lb by quarter end amidst a broader market sell-off in response to the war in the Middle East but recovered to $6.00/lb by mid-April. Although the war has had limited direct impact on copper supply or demand, some copper leaching operations in Africa and the Americas face disrupted supply of sulphuric acid. 

•     The US continues to import more copper cathode than is required to meet demand. This is despite the Chicago Mercantile Exchange (CME) price now trading at close to parity with the LME price, as markets await clarity on a potential future refined copper import tariff. 

•     The copper concentrate market remained extremely tight in Q1, with spot treatment and refining charges ending he quarter at a record low of -$95/t.

Aluminium

•     The Middle East conflict has removed significant ex-China aluminium supply, with smelter curtailments resulting in expectations of an enhanced global deficit in 2026.

•     Logistics and bauxite supply disruptions (Strait of Hormuz, war risk insurance) lifted seaborne freight costs and China bauxite CIF prices towards the end of the quarter. In addition, prices were supported on higher Guinean export control uncertainty.

•     The LME price rallied in Q1 reaching nearly four-year highs in March, driven by supply disruption in the Middle East which accounts for 23% of ex-China production. Visible aluminium inventories tightened outside China as demand held broadly stable. Spot market premiums rallied in Japan and Europe; the US Midwest duty paid premium ended the quarter at a record high of $2,523/t.

•     Australian FOB alumina price remained subdued in Q1 due to weaker Middle East alumina demand and higher output in Indonesia and China. Alumina stocks remained elevated in China.  

Lithium 

•     Lithium carbonate prices continued to rally in Q1, driven by growing expectations of market tightness in 2026 amid strong demand for Battery Energy Storage Systems (BESS), policy-related mine curtailments in China and export restrictions in Zimbabwe.

•     Global EV sales were down 8% YoY YTD February following a pullback in policy support in China and the US.

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. 

•     Q1 production: Second highest Q1 since 2018 and up 13% YoY, driven by continued investment in mine health and productivity, and fewer weather impacts.

•     Q1 sales: Up 2% YoY, driven by strong mine performance. Tropical Cyclones Mitchell (February) and Narelle (March) impacted shipments by approximately 8 Mt, with effects extending into early Q2. Around half of weather losses are expected to be recovered. SP10 represented 12% of total sales, in line with Q4 2025.

•     Q1 sales: 8% 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.

◦     25% of sales were made on a free on board (FOB) basis, with remainder sold including freight.

•     Q1 portside sales in China: 2.6 Mt (8.6 Mt in Q1 2025)

◦     100% of our portside sales were either screened or blended in Chinese ports.

◦     End-March inventory levels at portside were 6.6 Mt, including 3.2 Mt of Pilbara product.

¹ Simandou production represents crushed ore at the SimFer mine gate before train loading.

² Simandou sales will represent ore which has been through tertiary crushing in China and collected by the customer. 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, and collection of final product by the customer.

³ 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.

•     Q1 production: Following the tragic fatality, mine operations were progressively resumed over one month. Ore continues to be crushed utilising temporary crushing facilities, with first ore expected through permanent crushing facilities in H2 2026. As at the end of Q1, 2.1Mt (100%) of crushed ore has been stockpiled at the mine gate ready for loading.

•     Q1 sales: 0.6 Mt (100%) was shipped to China during the quarter. First sales have been realised in April.  

6. Aluminium & Lithium

Aluminium

Rio Tinto share of production ('000 tonnes)	Q1 2026	vs Q1 2025
Bauxite	13,281	-11      %
Bauxite third party shipments	9,018	-8         %
Alumina1	2,038	+6        %
Aluminium	835	+1        %
Recycled aluminium	61	-8         %
1 As stated in Q1 2025, following sanction measures by the Australian Government, Rio Tinto has taken on 100% of capacity of Queensland Alumina Limited (QAL). With the end of the QAL participation agreement at the end of December 2024, QAL and Rio Tinto have entered into a new two-year tolling agreement for 100% of the capacity, effectively making QAL a tolling entity exclusively for Rio Tinto. This additional output is excluded from the production tables in 2025; however, for 2026, we have now included QAL on a 100% basis.

Bauxite

•     Q1: Production was mainly affected by significant weather disruption at Weipa in January and February (record rainfall for the past decade), followed by shutdowns at Weipa and Gove in March due to Cyclone Narelle (0.9 Mt production impact). Despite these impacts, production guidance remains unchanged.

Alumina

•     Q1: Strong performance, with QAL now included at 100% (from 80% in 2025), partly offset by weather-related disruption across the Pacific refineries.

Aluminium

•     Q1: Production remained resilient, despite planned ramp-down at Arvida, demonstrating underlying portfolio improvement.

◦     Kitimat: Continued ramp-up following improved hydrological conditions and power supply which resulted in improved operational performance.

◦     NZAS: Production rates remain high following full ramp-up in Q4 2025.

◦     Arvida: One potline successfully closed in March, with the two remaining potlines to close by year-end as AP60 ramps up following first hot metal in March.

•     At Boyne Smelters Limited (BSL), we secured a landmark A$2 billion joint funding package from the Queensland and Australian Governments, alongside new renewable power arrangements, to  extend operations to at least 2040.

Tariffs

•     Q1: All produced metal was shipped, with sales pricing, product mix, and shipping destinations flexed to optimise outcomes in a changing market environment. Total tariff costs decreased in Q1, primarily reflecting lower total shipments to the US (273 kt vs 303 kt in Q4), including both tariff‑impacted and exempt products.

	H1 2025	H2 2025	Q4 2025	Q1 2026
Total RTA shipments - US destination, kt1	723	630	303	273
Total RTA tariff cost, $m	321	709	416	362

1 Including both tariff impacted and exempt products. 2 Mid-west premium duty paid applies to approximately 40% of our total volumes.

Recycled aluminium

•     Q1: Recycled aluminium production was relatively stable QoQ. Production remained below Q1 2025, reflecting changes made in the downstream operating footprint from Q2 2025.

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 2025 first quarter lithium carbonate equivalent production from Arcadium was 17.2kt (20.0kt on a 100% basis) of which 5.6kt was produced since completion of the acquisition in March (6.5kt on a 100% basis), lithium carbonate equivalent shipments from Arcadium was 12.1kt (15.2kt on a 100% basis) of which 3.8kt was shipped since completion of the acquisition in March 2025 (5.0kt on a 100% basis). Rincon production is now included in Q1 2026.

^•           Q1: Lithium carbonate equivalent (LCE) production was lower YoY, primarily reflecting that Mt Cattlin was in operation in Q1 2025 (now in care and maintenance since end of March 2025).

◦     Olaroz: Impacted by early-year heavy rainfall along with subsequent low evaporation rates.

◦     Fenix: Affected by weather but to a lesser extent than in Q1 2025.

◦     Rincón starter plant: Continued to ramp up and delivered higher output versus the previous quarter, partially offsetting weather‑related disruptions.

7. Copper

Total copper production (consolidated basis1)	229	+9        %
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 7 thousand tonnes of cathode produced from purchased concentrate in Q1 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

•     Q1: Lower cathode production due to low anode inventory impacted by unplanned maintenance at the smelter. Lower concentrator throughput from geotechnical constraints partially offset by slightly higher recoveries.

•     YoY: Lower cathode production due to low anode inventory, which was impacted by unplanned maintenance at the smelter. Higher concentrator throughput combined with higher grades partially offset by lower recovery rates. 

Escondida

•     Q1: Lower production driven by planned lower copper grades in line with mine sequencing and lower throughput, partially offset by improved Full Sal¹ cathode production.

•     YoY: Lower production driven mainly by planned lower ore grades in line with mine sequence, partially mitigated by higher throughput, better recoveries and increased cathode output.

Oyu Tolgoi

•     Q1: Slightly lower production due to planned shutdown leading to lower ore milled, partly offset by modestly higher combined headgrade and recovery rates.

•     YoY: Increased contribution from underground material supported by the conveyor to surface, combined with higher grades from the open pit and underground. The full commissioning of the concentrator conversion (including ball mill 5) and optimised blending of open pit ores lifted copper and gold recoveries by 6 and 8 percentage points, respectively, YoY.

•     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.

•     Our engagement with the Government continued, including for the Entrée licence transfer. We continue to maintain flexibility and options in the mine plan, including bringing Panel 1 or Panel 2 South into production first, depending on the timing of the licence transfer.

¹ Full SaL is a processing technology that allows the extraction of copper using chlorine-assisted leaching predominantly for sulphidic 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.

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 crushed ore at the SimFer mine gate before train loading: 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) 2025 first quarter lithium carbonate equivalent production from Arcadium was 17.2kt (20.0kt on a 100% basis) of which 5.6kt was produced since completion of the acquisition in March (6.5kt on a 100% basis), lithium carbonate equivalent shipments from Arcadium was 12.1kt (15.2kt on a 100% basis) of which 3.8kt was shipped since completion of the acquisition in March 2025 (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 crushed ore at the SimFer mine gate before train loading: 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 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.

(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) Simandou sales will represent ore which has been through tertiary crushing in China and collected by the customer. 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, and collection of final product by the customer.

(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 2.1wmt (100% SimFer) stockpiled ore at the Simfer mine gate.

(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) Includes all shipments from Pilbara and IOC, including those to our Portside trading business; Excludes shipments from our Portside

trading business. Simandou sales will represent ore which has been through tertiary crushing in China and collected by the customer. 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, and collection of final product by the customer.

(g) 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 crushed ore at the SimFer mine gate before train loading: 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 and collection of final product by the customer.

(a) Lithium carbonate quantities reflect our 100% share of Olaroz shipments, of which Rio Tinto's ownership is 66.5%.
(b) 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.
(c)  Full first quarter lithium carbonate equivalent production from Arcadium was 17.2kt (20.0kt on a 100% basis) of which 5.6kt was produced since completion of the acquisition in March (6.5kt on a 100% basis). Full first quarter lithium carbonate equivalent shipments from Arcadium was 12.1kt (15.2kt on a 100% basis) of which 3.8kt was shipped since completion of the acquisition in March (5.0kt on a 100% basis).
