Sulfur Supply Disruptions Threaten Copper Cathode Production

Copper Cathode

Sulfur supply disruptions are emerging as a serious risk for copper cathode production as the US-Israeli-Iran war disrupts shipping and tightens global sulfur availability. Copper producers rely on sulfuric acid to leach, dissolve, and refine copper into high-purity cathode.

The Middle East supplies roughly one-quarter of global sulfur output, while nearly half of sulfur shipments pass through the Strait of Hormuz. A de facto closure of the route has delayed deliveries and raised concern across copper supply chains.

Sulfur supply disruptions matter because sulfur is the key feedstock for sulfuric acid. Without stable acid supply, copper producers face higher costs, slower processing, lower cathode output, and possible bottlenecks between mining and refining.

African Copper Producers Face the Highest Sulfuric Acid Risk

African copper producers face the greatest exposure because the Democratic Republic of Congo and Zambia depend heavily on imported sulfuric acid. Much of that supply moves through Middle East-linked shipping routes, making both countries vulnerable to prolonged logistics disruption.

Sulfuric acid plays a central role in electrowinning, where producers leach copper from lower-grade ore to create copper sulfate solution. Electrolysis then deposits copper onto cathode plates.

Sulfuric acid also supports electrorefining, where impure copper anodes dissolve in a sulfuric acid and copper sulfate solution. The process leaves impurities behind and plates 99.9% pure copper onto cathode starter sheets.

If acid supply remains tight, DRC and Zambian producers could face lower cathode output and higher operating costs. Ore stockpiling may also rise if refining capacity cannot keep pace with mined material.

Regional Exposure Could Reshape Refined Copper Premiums

China faces a second tier of exposure because its large smelting and leaching base requires substantial sulfuric acid supply. Chinese smelters generate sulfuric acid as a byproduct, which offers some short-term protection, but lower sulfur imports could still raise domestic acid prices and pressure leaching operations.

Chile and Peru appear more insulated because their copper industries rely more heavily on sulfide ore smelting, which produces sulfuric acid internally. Chile still has exposure through leaching operations, but both countries carry less direct risk than African cathode producers.

Sulfur supply disruptions could therefore reshape regional copper premiums if shortages persist. Refined cathode supply may tighten, production costs may rise, and consumers could increase their use of higher-grade copper scrap where substitution is technically feasible.

The Metalnomist Commentary

Sulfur is often treated as a secondary input, but this disruption shows its strategic role in copper refining. The copper market may focus on mine output, yet sulfuric acid availability can decide how much copper actually reaches cathode form.

Lithium-Ion Battery Copper Foil Shipments Surge as Ultra-Thin Products Gain Share

Copper Foil

Lithium-ion battery copper foil shipments rose sharply in 2025 as global battery production expanded and manufacturers shifted toward thinner materials to reduce copper costs. Global shipments reached 1.302mn t, up 41.7% from 2024, according to Chinese research institute EV Tank.

Lithium-ion battery copper foil demand remains closely tied to electric vehicle and energy storage growth. Copper foil is a key current collector in lithium-ion batteries, making it essential to cell performance, energy density and manufacturing cost.

Lithium-ion battery copper foil shipments were dominated by China, which accounted for 82.9% of global deliveries in 2025. EV Tank expects global shipments to reach 2.615mn t by 2030, implying continued expansion as battery output scales.

The product mix changed quickly during the year. The share of 8μm foil declined, while 6μm remained the mainstream product and accounted for more than 70% of total shipments.

Ultra-Thin Foil Gains Momentum on Copper Cost Pressure

Ultra-thin copper foil gained share as battery producers looked for ways to reduce copper input costs. Persistently high global copper prices pushed cell manufacturers to use thinner foil while maintaining battery performance.

The combined share of 5μm and 4.5μm ultra-thin foil rose to 24% in 2025. This is a major shift for a material category that requires tighter production control, better surface quality and stronger consistency.

Thinner copper foil can help reduce battery weight and improve energy density. It also lowers the amount of copper used per cell, which becomes increasingly important when copper prices remain elevated.

EV Tank expects 5μm and thinner foil to become a key material for high-end batteries. This reflects the industry’s move toward lighter, higher-energy-density cell designs.

However, thinner foil also raises manufacturing difficulty. Producers must control pinholes, tensile strength, elongation, surface roughness and coating compatibility more precisely.

That technical barrier could separate higher-end suppliers from lower-cost producers. As battery customers shift toward thinner grades, qualification and process reliability will become more important than simple capacity.

China Leads Supply as Competition Intensifies

China’s 82.9% share of global shipments shows its dominant role in battery copper foil supply. The country has built large-scale capacity around its lithium-ion battery ecosystem, supported by domestic EV, energy storage and cell manufacturing growth.

Competition intensified in 2025 as the market recovered and producers brought earlier-built capacity on line. This created a more fluid ranking among suppliers.

Longdian Wason ranked first with a 12.2% market share. Huachuang New Material followed after capacity ramp-ups lifted output and sales.

Defu Technology and Jiayuan Technology ranked third and fourth, respectively. Seven companies in the top 10 changed positions during the year, showing how quickly capacity, customer access and product mix are reshaping the sector.

Battery makers also increased procurement from second-tier suppliers to improve supply stability. This suggests buyers are trying to diversify supplier bases rather than rely only on leading producers.

For copper markets, the trend is strategically important. Battery copper foil growth creates a direct link between copper demand and battery technology. But the move toward ultra-thin foil also means battery growth will not translate into copper demand on a simple one-to-one basis.

The sector is therefore entering a more technical phase. Volume growth remains strong, but material intensity, foil thickness, supplier qualification and copper price pressure will all shape future demand.

The Metalnomist Commentary

The copper foil market shows how battery growth can lift copper demand while also forcing material thrift. High copper prices are pushing battery makers toward thinner foil, making technology and process control as important as raw capacity.

Paipote Copper Smelter Delay Pushes Chile’s Processing Expansion to 2031

Enami copper

Paipote copper smelter development in northern Chile is facing a delay of more than two years, pushing the country’s major state-backed smelting expansion further into the next decade. Chile’s national mining company Enami now expects construction of the $1.7bn project to begin in October and finish in February 2031.

The revised schedule replaces the earlier plan to start construction in February and complete the project by November 2028. The new dates were included in documents submitted to Chile’s environmental evaluation service, Sea.

Paipote copper smelter modernization is strategically important because Chile remains one of the world’s largest copper producers but has limited domestic smelting and refining capacity compared with its concentrate output. The delay extends the period in which more Chilean copper concentrate will continue to depend on overseas processing.

The project is designed to more than double smelting capacity at the Paipote metallurgical complex to 850,000 t/yr of copper concentrates. It will also include an electrolytic refinery capable of producing 240,000 t/yr of copper cathodes.

Engineering Changes Add Cost and Push Back Construction

The delay follows completion of detailed engineering studies for the smelter. Enami said the proposed changes to the original project, which was approved in October 2025, will cost $65mn.

The changes include demolition of existing infrastructure at the metallurgical complex. Some structures must be removed because of age, while others interfere with the new construction plan.

This is a common risk in brownfield metallurgical projects. Existing plants often provide strategic location and infrastructure advantages, but they can also create cost, demolition and layout challenges when new technology is added.

Enami’s filing seeks confirmation from Sea that the proposed changes do not need to be submitted to Chile’s environmental impact evaluation system. The outcome will matter for timing because any additional environmental review could further extend the project schedule.

The Paipote copper smelter delay also reflects the complexity of modern smelting projects. New plants must meet tighter environmental standards, handle higher concentrate volumes and integrate refining capacity while controlling emissions and operating costs.

For Enami, the project is more than a capacity expansion. The company suspended the existing smelter in 2024 to stem financial losses and improve environmental performance. The modernization is therefore intended to rebuild processing capability on a more sustainable and competitive basis.

Chile’s Copper Value Chain Remains Exposed to Processing Bottlenecks

The delay has wider implications for Chile’s copper value chain. Chile produces large volumes of copper concentrate, but domestic processing capacity has not expanded in line with mine output.

A larger Paipote complex would strengthen local copper concentrate processing and increase domestic cathode production. It would also support small- and medium-sized copper producers, which rely on Enami to process, smelt and refine their material.

That role is important for Chile’s mining structure. Major copper producers often have access to export markets and long-term concentrate buyers. Smaller producers depend more heavily on national processing infrastructure to convert output into marketable products.

The project’s planned 850,000 t/yr concentrate capacity would give Enami a much stronger position in Chilean smelting. The 240,000 t/yr cathode refinery would also help capture more value inside the country rather than exporting concentrate for overseas treatment.

However, the new 2031 completion date means these benefits will arrive later than planned. In the meantime, Chile remains more exposed to global treatment charges, overseas smelter availability and concentrate export logistics.

The delay also comes as copper demand is increasingly tied to grids, electrification, renewable energy, electric vehicles and industrial investment. Chile’s ability to capture more value from copper will depend not only on mine output, but also on smelting, refining and downstream processing capacity.

For Enami, execution will be critical. The company must manage engineering changes, environmental requirements, demolition, construction and financing while restoring confidence in Paipote’s long-term role.

For Chile, the project remains strategically necessary despite the delay. A modern Paipote copper smelter could improve domestic processing resilience and support a more integrated national copper industry.

The Metalnomist Commentary

The Paipote delay shows that copper resource leadership does not automatically translate into processing strength. Chile needs modern smelting and refining capacity to capture more value from its copper base, but brownfield execution risk remains a serious bottleneck.

Taseko Copper Earnings Rise as Higher Prices Offset Cost Pressure

Taseko Copper Mining

Taseko copper earnings improved in the first quarter as stronger realised copper prices and steadier mine output outweighed rising fuel, explosives and maintenance costs. The Canadian copper producer reported first-quarter earnings of C$93.5mn and net income of C$17mn, reversing a C$29mn loss a year earlier.

Taseko copper earnings were supported by revenue of C$237mn, up from C$139mn in the first quarter of 2025. Copper sales volumes rose by about 25% to 27mn lb, while realised copper prices increased to $5.74/lb, or $12,654/t, from $4.24/lb a year earlier.

Taseko copper earnings show how higher copper prices can quickly improve financial performance for established producers. However, the quarter also highlights the cost inflation facing mine operators, especially those exposed to diesel, explosives and unplanned maintenance.

The result reinforces a wider copper market theme. Strong prices can support margins, but mine cost structures remain under pressure as operators process complex assets and manage equipment reliability.

Gibraltar Stabilises Output but Costs Move Higher

Gibraltar remained Taseko’s main cash generator in the first quarter. The mine produced 30mn lb of copper, stabilising after earlier disruption from maintenance issues and a serious accident that previously pushed output below guidance.

The stable output was important because Gibraltar still dominates Taseko’s operating base. Florence has begun production, but Gibraltar remains the asset that drives near-term revenue, cash flow and earnings.

However, Gibraltar’s unit costs increased. Costs rose to $2.63/lb from $2.47/lb in the previous quarter and $2.26/lb a year earlier.

The increase was driven by higher diesel prices, explosives costs and unplanned maintenance. These cost pressures are significant because they can dilute the benefit of higher copper prices.

For copper miners, diesel and maintenance are not secondary issues. They directly affect haulage, equipment availability, mine sequencing and operating margins.

Gibraltar’s performance therefore sends a mixed signal. Production stability has improved, but cost control remains a key challenge if Taseko wants to fully capture the upside from higher copper prices.

Florence Adds US Copper Output but Remains Early-Stage

The Florence mine in Arizona produced its first commercial copper during the quarter. Output reached 1.5mn lb, marking an important milestone for Taseko’s US growth strategy.

Florence remains small compared with Gibraltar, but its first production gives Taseko a second operating source of copper. This improves the company’s long-term portfolio balance if output can ramp successfully.

The Arizona asset is strategically important because the US is trying to strengthen domestic copper supply. Copper demand is rising from grids, electrification, manufacturing reshoring and data centre infrastructure.

However, Florence has not yet become the rapid growth engine once expected. The project must still scale output, prove operating consistency and contribute meaningfully to group cash flow.

For Taseko, the near-term story remains Gibraltar plus price leverage. Florence adds strategic optionality, but the company’s earnings are still most sensitive to copper prices and Gibraltar’s cost performance.

The first-quarter result also shows why copper producers are receiving more investor attention. When realised prices rise sharply, even mid-sized producers can see rapid earnings recovery.

Still, the market will watch whether higher costs continue to climb. If diesel, explosives and maintenance inflation persist, copper miners may need even stronger prices to protect margins.

The Metalnomist Commentary

Taseko’s quarter shows that copper price strength can repair earnings quickly, but it cannot hide mine-level cost inflation. The strategic upside lies in Florence, yet Gibraltar’s cost discipline will decide how much of the copper rally Taseko actually converts into cash.

China’s Copper Scrap Imports Drop in September Amid Narrowing Price Spreads

Copper Scrap

China’s copper scrap imports declined by 5.4% in September, reflecting market shifts driven by narrowing price spreads between refined copper and copper scrap. According to market participants, the spread, which began at over 2,000 yuan per ton (Yn/t) at the start of August, contracted to around 1,200 yuan/t ($169/t) by the end of the month as copper prices hit a five-month low.

Market Dynamics and Buyer Behavior

The narrower price spread dampened the interest of fabricated product producers in purchasing scrap. Many Chinese copper smelters and secondary producers chose to remain on the sidelines, avoiding major scrap purchases once the spread fell below the perceived reasonable threshold of 1,400 yuan/t.

At the same time, sellers exhibited hesitancy to deliver copper scrap during August's price slump, preferring to wait for higher prices. This shift in behavior further impacted the availability and movement of scrap in September.

The Broader Impact of Rising Costs

Adding to the complexities, many refined copper producers opted to use copper scrap as a substitute for copper concentrate. This switch was driven by the significantly higher costs of copper concentrate, leading to a 16% rise in China’s copper scrap imports during the January-September period.

However, the copper concentrate market faced its own challenges, including a persistent supply crunch that resulted in a sharp 85% drop in treatment and refining charges (TC/RCs) over the same timeframe.

Outlook

With copper prices and market conditions remaining volatile, China’s copper trade dynamics are expected to continue adjusting as producers and buyers navigate fluctuating costs and price spreads.

BHP Copper Production Falls as Escondida Grades and Pampa Norte Weaken

BHP

BHP copper production fell in January-March as lower output from Escondida and Pampa Norte outweighed stronger results from South Australia and Antamina. The Australian mining group produced 476,800t of copper during the quarter, down 7.1% from a year earlier and 2.8% from the previous quarter.

BHP copper production remains within the company’s wider plan for the July 2025-June 2026 fiscal year. The miner kept its overall copper guidance unchanged at 1.9mn-2mn t, suggesting that first-quarter weakness is still manageable at group level.

The result shows the operational complexity behind global copper supply. Escondida remains a major copper asset, but lower feed grades reduced concentrate output despite higher concentrator throughput. Pampa Norte also weakened sharply, forcing BHP to lower guidance for the operation.

BHP copper production is strategically important because copper demand is increasingly tied to grids, electrification, data centres, renewable energy and industrial infrastructure. Any weakness from major producers matters in a market already focused on mine grades, project delays and supply-chain fragility.

Escondida and Pampa Norte Drive Quarterly Copper Decline

Escondida remained the central pressure point in BHP’s quarterly copper performance. Copper concentrate output at the Chilean operation fell by 14% on the year to 248,300t.

The decline was mainly caused by lower feed grades. Escondida’s average copper feed grade fell to 0.88% from 1.09% a year earlier, reducing concentrate production even though concentrator throughput rose by 4.1% to 34.2mn t.

This is an important signal for copper markets. Higher throughput cannot fully offset grade decline when ore quality deteriorates. Large copper mines increasingly need to process more material to maintain output, raising energy, water, equipment and cost pressure.

Escondida’s cathode production moved in the opposite direction. Copper cathode output rose by 22% to 54,900t because of improved sulphide leach performance.

That improvement helped soften the broader decline. However, concentrate weakness still mattered because Escondida is one of the world’s most important copper operations and a major contributor to BHP copper production.

BHP expects Escondida output for July 2025-June 2026 to reach the upper half of its 1.2mn-1.275mn t guidance range. This suggests that the company still expects stronger performance across the fiscal year despite the lower quarterly concentrate result.

Pampa Norte was a clearer negative. BHP produced 25,700t of copper concentrate and 18,900t of copper cathode at the mine, down 29% and 41% year on year, respectively.

Cathode output fell because of lower planned stacked copper grade. Concentrate output declined because of weaker recovery rates.

As a result, BHP lowered Pampa Norte production guidance to 210,000-220,000t from the previous range of 230,000-250,000t. This was the main guidance cut in the company’s copper portfolio.

Pampa Norte’s weaker outlook reinforces a broader industry issue. Copper mines are not only exposed to headline ore volumes. They are exposed to grades, recovery rates, leach performance, maintenance timing and processing efficiency.

South Australia and Antamina Offset Part of the Weakness

BHP’s South Australian operations provided partial support. Copper concentrate output rose by 22% to 27,500t, while cathode production slipped by 2.3% to 55,300t.

The improvement was supported by higher feed grades at Prominent Hill and higher mined and milled volumes at Olympic Dam. This helped balance weaker results from Chile.

BHP kept South Australian copper guidance unchanged at 310,000-340,000t. The stability of this guidance is important because South Australia remains a strategic copper growth region for the company.

Antamina also performed strongly. BHP’s copper output from the Peruvian operation rose by 43% to 44,100t, supported by better feed grades and improved operational performance.

The stronger Antamina result prompted BHP to lift production guidance to 150,000-160,000t from the previous 140,000-150,000t. This upgrade helped offset the Pampa Norte downgrade at portfolio level.

The mixed operating picture explains why BHP maintained total copper guidance. Escondida and Pampa Norte reduced quarterly output, but South Australia and Antamina provided enough support to keep the group’s broader plan intact.

BHP also completed the sale of its Carajas asset to CoreX Holdings on 2 April for $240mn, with up to $225mn in contingent payments. The sale reflects ongoing portfolio management as BHP concentrates capital on larger strategic assets.

For copper markets, the key message is that supply growth remains uneven. Stronger performance at one asset can offset weakness elsewhere, but global mine supply still depends on operational execution across a small number of large producers.

BHP copper production will therefore remain a closely watched indicator through the rest of the fiscal year. The market will focus on whether Escondida grades stabilise, Pampa Norte recovers, and South Australia and Antamina continue to outperform.

The Metalnomist Commentary

BHP’s quarter shows that copper supply risk is increasingly operational, not only geological. Lower grades, weaker recoveries and leach performance can quickly offset throughput gains, keeping the market sensitive to every large-mine update.

Codelco Copper Output Stabilises as Middle East Crisis Raises Cost Risk

Codelco

Codelco copper output stabilised in 2025, but rising energy, diesel, reagent and logistics costs linked to the Middle East crisis could complicate the company’s recovery path. Chile’s state-owned copper producer reported a 0.5% increase in copper output to 1.33mn t, while total attributable production reached 1.44mn t.

The modest improvement showed that Codelco copper output has started to recover after several years of operational pressure. However, the company still faced mixed performance across major divisions, including lower output at El Teniente, Chuquicamata and Gabriela Mistral.

Codelco copper output is expected to rise only slightly in 2026 to 1.331mn–1.357mn t. That guidance highlights the limited pace of supply growth at one of the world’s most important copper producers, even as demand from grids, electrification and industrial investment remains structurally strong.

Fuel and Sulphuric Acid Costs Threaten Copper Margins

The Middle East crisis is creating a new cost risk for copper producers. If disruption around the Strait of Hormuz persists, higher diesel prices, tighter logistics and rising input costs could feed directly into mining cost structures.

Diesel is a key cost driver for haulage, power generation, processing and mine-site operations. Market participants estimate that copper mining costs can rise by 5–10% for every $50/bl increase in oil prices, making fuel volatility a direct margin threat.

Sulphur supply is another concern because it is used to produce sulphuric acid for copper leaching. This risk is especially acute for hydrometallurgical producers in the African Copperbelt, but higher global acid costs could still affect broader copper market sentiment.

Codelco’s own cost base was already rising before the latest geopolitical shock. Direct cash costs increased 4.8% to $2.09/lb in 2025, while total costs rose 14% to $3.73/lb because of higher operating activity, exchange-rate effects and inflation.

Stable Output Masks Deeper Structural Pressure

Codelco described 2025 as a year of stabilisation and productive transition. Ministro Hales lifted output by 25% to 153,000t, while Radomiro Tomic increased production by 9.2% to 295,000t.

However, several core assets remained under pressure. El Teniente output fell 13% to 310,000t, Chuquicamata declined 8% to 265,800t, and Gabriela Mistral dropped 20% to 82,000t.

The company also reported record capital expenditure of $5.07bn in 2025, showing the rising investment required to sustain production. Deeper deposits, lower ore grades and more complex operations are making copper supply more capital-intensive.

This reinforces the longer-term copper supply challenge. Even with stabilising production, Codelco’s guidance points to only incremental growth, while cost inflation could delay marginal projects and pressure higher-cost operations if the conflict continues.

The Metalnomist Commentary

Codelco’s results show that copper supply risk is shifting from simple output loss to cost inflation and capital intensity. The market may still focus on tonnes, but diesel, sulphuric acid and project execution costs will increasingly decide how much copper supply can grow profitably.

MMG copper output 2025 hits seven-year high on Las Bambas surge

MMG

MMG copper output 2025 hit a seven-year high as the Chinese miner leveraged strong performance at Las Bambas in Peru. MMG copper output 2025 reached 506,899t, with growth underpinned by record ore mined, processed and recovered across its global portfolio. As a result, MMG copper output 2025 highlights how Chinese-backed assets are reshaping global copper supply and treatment charge dynamics.

Las Bambas and Khoemacau anchor MMG’s copper growth

Las Bambas drove most of the increase in MMG copper output 2025. The Peruvian mine produced 410,834t of copper in concentrate, up 27pc year on year. Higher ore mining rates, improved plant throughput and stronger recovery combined to lift site performance.

MMG set a 400,000t production target for Las Bambas in 2026, signalling confidence in the mine’s stability. However, community risks and logistics in Peru will remain key watchpoints for traders and smelters. Higher sustained output from Las Bambas will reinforce Peru’s position as a core supplier to Asian and Atlantic copper markets.

Khoemacau in Botswana added new growth momentum to MMG’s profile. The mine delivered 42,120t of copper concentrate in 2025, up 36pc from 2024. MMG plans to expand Khoemacau’s capacity to 130,000 t/yr by 2028, with longer-term potential to reach 200,000 t/yr after further studies.

DRC expansion and tightening treatment charges

MMG’s Kinsevere operation in the Democratic Republic of the Congo contributed to the stronger MMG copper output 2025. Copper cathode production at Kinsevere rose 18pc to 52,791t. An expansion project, which delivered its first cathode in late 2024, should push annual output to 65,000–75,000t in 2026. This reinforces the DRC’s role as a key growth hub for refined copper supply.

Meanwhile, MMG reported a mixed picture in other base metals. Zinc output increased by 6pc to 232,060t, while lead production slipped 5pc to 39,608t. However, the broader copper concentrate market remained the tightest stress point for smelters. Concentrate supply lagged new smelting capacity, pushing treatment and refining charges (TC/RCs) deep into negative territory.

Smelter TC/RC benchmarks turned sharply lower through 2025, reflecting a continued shortage of clean copper concentrate. The Metalnomist smelter purchase index fell from slightly positive levels in early 2025 to significantly negative by year-end. Trader purchase indices weakened even further as competition intensified for spot tonnes. This environment favours well-positioned miners like MMG with scalable, low-cost concentrate streams.

Strategic implications for global copper supply

The step-up in MMG copper output 2025 underscores the influence of Chinese state-linked capital in strategic copper regions. Las Bambas, Khoemacau and Kinsevere together form a diversified platform across Peru, Botswana and the DRC. This geographic spread reduces single-asset risk while deepening China’s indirect exposure to offshore copper units.

For smelters, MMG’s growth slightly eases concentrate tightness but does not fully resolve structural deficit. New Asian and European smelting projects continue to outpace mine supply growth, keeping downward pressure on TC/RCs. As a result, smelters face margin squeeze unless by-product credits or premiums can offset weaker treatment terms.

Downstream, strong MMG copper output 2025 supports long-term energy transition demand. Additional tonnes from Las Bambas and future Khoemacau expansions will feed wiring, renewables, EVs and grid investments. However, the aggressive project pipeline also depends on stable permitting, local community relations and predictable fiscal regimes in host countries.

Focus keyphrases: MMG copper output 2025, Las Bambas copper, Khoemacau Botswana copper, Kinsevere DRC copper, copper concentrate TC/RCs, global copper supply growth

The Metalnomist Commentary

MMG copper output 2025 reinforces the miner’s position as a pivotal supplier into a structurally tight copper concentrate market. While rising volumes from Las Bambas, Khoemacau and Kinsevere are welcome news for smelters and traders, they arrive in a world where new refining capacity still outstrips mine growth. Expect continued pressure on TC/RCs and a premium for diversified, scalable copper producers like MMG as the energy transition accelerates.

Copper Supply Chain Fragility Is Underpriced Despite Price Rally

Ivanhoe

Copper supply chain risk is still being underpriced even after London Metal Exchange prices rallied above $13,000/t, according to Ivanhoe Mines chairman Robert Friedland. He warned that higher prices alone will not quickly unlock new mine investment or solve the operational bottlenecks now shaping copper supply.

The copper supply chain is facing a more complex problem than headline market balances suggest. Friedland pointed to sulphur, sulphuric acid, diesel and other critical inputs as increasingly important constraints for mining operations, especially in Africa.

The copper supply chain is particularly exposed in the Democratic Republic of Congo, where a large share of production depends on acid leaching. If sulphuric acid availability tightens further, Friedland said about half of the DRC’s low-grade leached copper could be at risk unless higher copper prices offset sharply higher acid costs.

This warning comes as the Middle East conflict affects copper markets indirectly. The immediate threat is not concentrate supply, but sulphur-linked cost inflation that can raise operating costs for solvent extraction and leaching operations.

Sulphuric Acid and Diesel Risks Expose Mining Cost Vulnerability

Sulphuric acid has become a central issue for copper supply because much of the DRC’s production relies on acid leaching. A prolonged disruption in sulphur flows could affect roughly 3mn t/yr of DRC copper output, making the country one of the most exposed parts of the global copper market.

The DRC’s vulnerability is different from that of traditional concentrate producers. Concentrate supply depends on mining, milling, logistics and smelter demand. Leached copper also depends on steady sulphur or sulphuric acid access, which creates another layer of supply-chain risk.

Ivanhoe’s Kamoa-Kakula complex is unusually positioned because it produces sulphuric acid as a by-product rather than relying only on external supply. The operation produced more than 100,000t of sulphuric acid in the first quarter of 2026, with annual output expected to reach 600,000-700,000 t/yr once the new smelter is fully ramped up.

That acid production gives Ivanhoe a strategic advantage. It can reduce exposure to imported acid costs while supporting copper output in a market where other DRC producers may face tighter reagent availability.

Diesel is another operational risk. Remote mines depend on diesel for haulage, power generation and logistics, especially where grid access is weak or transport routes are long.

Friedland said highly exposed mining firms should consider securing up to a year of diesel supply. He also argued that the DRC may be less vulnerable than some expect because refined products can arrive through India, Nigeria and southern Africa.

Still, the full operational impact may not yet be visible. Supply-chain shocks often appear first through higher costs, longer lead times and working-capital pressure before they become production losses.

This is why the copper market may be misreading risk. Visible inventories and annual balances can suggest moderate surplus, while the physical supply chain becomes more fragile beneath the surface.

A copper price above $13,000/t helps margins, but it does not immediately create acid, diesel, spare parts, qualified labour or new mine capacity. Mine investment still depends on permitting, capital cost, political risk and long development timelines.

AI, Data Centres and Critical Metals Raise Copper’s Strategic Value

Friedland linked copper’s long-term importance directly to electrification, cooling systems, data centres and artificial intelligence. These sectors are turning copper from a conventional industrial metal into a strategic infrastructure material.

AI data centres need large amounts of power infrastructure. That means more copper for grids, substations, transformers, cooling systems, cabling, backup power and electrical distribution.

The growth of AI also reinforces demand for metals beyond copper. Friedland highlighted gallium, scandium, dysprosium, rhenium and tantalum as thinly traded materials with low liquidity but high industrial dependence.

This is an important market signal. The next phase of industrial competition will not depend only on bulk metals. It will also depend on access to small-volume strategic materials that support semiconductors, aerospace, defence, magnets and high-performance alloys.

Copper remains the anchor metal because it connects electrification, grid expansion, industrial automation and data infrastructure. Friedland described copper as the “king of metals” because no large-scale energy transition can move without it.

However, copper’s strategic value also exposes the market to policy pressure. The US is beginning to understand mining’s national security role more clearly, especially as domestic supply concentration and import dependence become more visible.

Market participants expect moderate global copper surpluses this year, helped by last year’s supply windfall. But US physical balances are expected to remain tight, with the CME-LME arbitrage reopening to encourage flows into the country.

That regional tightness matters. Copper may look balanced globally, while specific markets face procurement pressure because of tariffs, logistics, exchange spreads, domestic manufacturing needs or strategic stockpiling.

The broader lesson is that copper pricing must account for supply-chain resilience, not only mine output. A mine that lacks acid, fuel or logistics capacity cannot deliver metal reliably, even if ore is available.

For investors, this strengthens the value of hard assets with low obsolescence. Mines, smelters, acid plants, power infrastructure and logistics corridors are becoming more valuable as supply chains become less predictable.

For manufacturers, copper procurement is becoming a strategic function. Buyers linked to grids, data centres, defence, cooling systems and energy infrastructure will need more secure supply agreements, not only exposure to exchange prices.

The Metalnomist Commentary

Friedland’s warning cuts through the headline copper rally: the market is pricing metal, but not enough supply-chain fragility. Copper’s next constraint may come less from ore availability and more from acid, diesel, logistics and the minor metals needed to build the electrified economy.

LME Copper Cathode Supply Could Rise as Chinese Smelters Push EQ Listings

Chinese Copper

LME copper cathode supply could increase as more Chinese smelters seek to register equivalent quality cathodes on the London Metal Exchange. The move reflects a push to capture higher premiums for material that is close to LME-registered brands in quality.

The near-term impact on LME copper cathode supply is likely to be limited. However, more registrations could gradually widen deliverable copper availability and give buyers more alternatives to traditional registered cathode brands.

Chinese smelters are targeting the premium gap between EQ cathode and fully registered material. African-origin registered copper usually earns a higher premium than EQ cathode, but it still trades below Chilean registered brands because many African cathodes are solvent-extraction and electrowinning products with slightly higher impurity levels.

DRC Cathode Listings Expand China-Linked LME Supply

The London Metal Exchange recently approved China Nonferrous Mining’s SMD copper cathode brand for listing. The brand is produced at the Deziwa project in the Democratic Republic of Congo, which has copper cathode capacity of 80,000 t/yr.

The Deziwa project is jointly owned by CNMC and the DRC’s state-owned mining company. It hosts 4.6mn t of copper metal resources and 420,000t of cobalt metal resources, giving it strategic value across both copper and battery metal supply chains.

CNMC’s production profile also shows a shift toward more refined copper output. The group produced 130,232t of copper cathode in 2025, up 3% from a year earlier, while copper blister output fell by 33% to 192,266t.

The LME has also approved CMOC’s TFM 1 copper cathode brand for listing. That brand is produced at Tenke Fungurume in the DRC, reinforcing the country’s growing role in exchange-deliverable copper supply.

Premium Strategy Could Reshape Refined Copper Trade Flows

LME copper cathode supply strategy is becoming more important as Chinese-linked producers look to improve market access and price realisation. Listing cathode brands can improve buyer acceptance, increase liquidity and narrow discounts against established registered brands.

The DRC is already China’s largest source of copper cathode imports. China imported 1.44mn t of copper cathode from the DRC in 2025, equal to 37.6% of total imports.

More LME-approved DRC brands could change how buyers view African cathode. If quality, documentation and deliverability improve, some buyers may become less dependent on higher-premium registered material from other origins.

Still, the immediate effect should remain modest. LME registration does not automatically mean large volumes will flow onto warrant, but it does increase optionality for producers, traders and consumers in a market where brand status affects pricing power.

The Metalnomist Commentary

The Chinese EQ cathode push shows that copper competition is moving into brand approval, deliverability and premium capture. The bigger implication is that DRC copper is becoming not only a Chinese import source, but a growing part of the LME-recognised refined copper system.

Glencore Copper Production Rises as DRC Cobalt Quota Reshapes Output Priorities

Glencore

Glencore copper production rose sharply in the first quarter as higher grades at its African copper mines and stronger throughput at Antamina lifted output. The Switzerland-based trading and mining group produced 199,600t of copper, up 19% from a year earlier.

Glencore copper production growth contrasts with a steep fall in cobalt output. Own-sourced cobalt production dropped by 39% to 5,800t, mainly because the Democratic Republic of Congo’s export quota system has changed how producers manage shipments and mine planning.

Glencore copper production is now becoming more important inside its DRC asset base because cobalt export limits have made copper the clearer operating priority. This shift shows how state policy can directly reshape output behaviour in multi-metal mining systems.

The company maintained full-year production guidance for copper, nickel and zinc, despite weaker output in several other metals. Copper guidance remains at 810,000-870,000t for the year.

DRC Quota System Pushes Cobalt Lower

The sharp fall in cobalt output reflects the DRC’s quota system, introduced after the country moved away from its earlier export ban framework. The system capped shipments and set annual limits for 2026-27, with an additional strategic pool.

For Glencore, the practical effect is clear. Its DRC assets are now prioritising copper production because copper can move through the market with fewer quota-related constraints.

This matters for battery and superalloy supply chains. The DRC remains the world’s dominant source of mined cobalt, so export policy can quickly affect availability, pricing and producer behaviour.

Cobalt is not produced in isolation at many Congolese operations. It is often linked to copper mining, which means policy limits on cobalt can influence mine sequencing, processing priorities and inventory decisions.

The first-quarter numbers therefore point to a more managed cobalt market. Supply is not only a function of ore grades and plant capacity. It is increasingly controlled by export approvals, quotas and state strategy.

Copper benefited from stronger grades at African operations and higher throughput at Antamina in Peru. That performance reinforces copper’s stronger strategic position at a time when demand from grids, electrification, industrial policy and data centres continues to attract market attention.

Nickel, Zinc and Ferro-Chrome Show Operational Pressure

Glencore’s nickel output fell by 9% to 17,200t. The decline was caused by a furnace disruption at the Sudbury complex in Canada, which affected matte shipment timing to Norway.

Nickel guidance remained unchanged at 70,000-80,000t. This suggests Glencore sees the first-quarter weakness as manageable rather than a full-year supply reset.

Zinc output fell by 17% to 176,900t. The decline was mainly linked to the closure of the Lady Loretta mine in Australia and lower output from Kazzinc in Kazakhstan.

Zinc guidance also remained unchanged at 700,000-740,000t. However, the first-quarter result shows how mine closures and regional production issues can still weigh on quarterly availability.

Ferro-chrome output collapsed by 95% to 13,000t because of continued care and maintenance at Glencore’s chrome smelting operations and the phased restart of the Lion Smelter in South Africa.

South African ferro-chrome remains under pressure from high energy prices and competition from lower-cost Chinese material. This has forced output cuts at major producers and weakened South Africa’s position in global ferro-alloy supply.

Glencore’s vanadium pentoxide production rose by 5% to 2,300t, offering a small positive signal in another strategic alloy material.

Overall, the quarter shows a company benefiting from copper strength while managing policy and cost pressures across cobalt, nickel, zinc and ferro-chrome. The most important signal is that copper and cobalt are now being shaped by very different forces: copper by grade and throughput, cobalt by DRC export control.

The Metalnomist Commentary

Glencore’s results show how government policy can be as powerful as geology in multi-metal supply chains. The DRC cobalt quota is not only reducing cobalt output; it is pushing producers to prioritise copper in one of the world’s most strategic mining regions.

Antofagasta Copper Output Falls as Los Pelambres and Centinela Weigh on First Quarter

Antofagasta

Antofagasta copper output fell in the first quarter of 2026 as lower production at Los Pelambres and Centinela reduced group supply. The Chilean miner produced 143,000t of copper during the quarter, down 7.6% from a year earlier.

The decline also affected sales. Antofagasta copper sales fell by 19.5% on the year to 137,000t, reflecting weaker quarterly output and the timing of shipments.

Antofagasta copper output is expected to improve through the year as maintenance at Los Pelambres is completed and ore processing rates and grades recover. The company expects 2026 production to rise quarter on quarter after the first-quarter slowdown.

The result is important for the copper market because Chile remains one of the world’s most important supply regions. Any operational weakness at major Chilean producers can influence concentrate availability, refined copper expectations and market sentiment.

Los Pelambres Maintenance and Centinela Grades Hit Copper Supply

Los Pelambres remained Antofagasta’s largest copper producer in the first quarter, but output fell by 5.2% on the year to 66,300t. The decline was mainly caused by ongoing major plant maintenance.

Maintenance-related weakness is usually temporary, but it can still affect quarterly supply. Los Pelambres is a key asset for Antofagasta, so any reduction in availability has a direct impact on group production.

Centinela recorded a sharper decline. First-quarter copper output at the unit fell by 12.4% on the year to 48,700t.

Centinela concentrate production edged down by 0.6% to 35,700t because of lower grades and weaker ore processing rates. Cathode output fell much more sharply, dropping by 34.3% on the year to 13,000t.

The performance shows that Antofagasta’s production pressure was not limited to one mine. Maintenance at Los Pelambres, lower grades at Centinela and weaker cathode output all contributed to the first-quarter decline.

Output also softened at the group’s smaller assets. Antucoya production fell by 3% on the year to 19,600t, while Zaldivar output decreased by 7.8% to 8,300t.

This broad decline highlights the operational challenge facing copper producers. Even when demand fundamentals remain supportive, mine output can be affected by maintenance schedules, ore grades, processing rates and asset maturity.

Molybdenum Holds Relatively Stable as Copper Recovery Depends on Operations

Antofagasta’s molybdenum production was relatively stable compared with copper. Group molybdenum output reached 3,000t in the first quarter, down 3.2% from the same period last year.

The result reflected a balance between higher molybdenum recoveries and lower ore processing rates. This helped limit the decline despite weaker copper throughput at key concentrators.

Molybdenum output at Centinela fell by 12.5% on the year to 700t. Los Pelambres molybdenum production remained unchanged at 2,300t, helping stabilise the group result.

Molybdenum remains strategically important because it is used in stainless steel, special steels, energy infrastructure, defence applications and high-performance alloys. Stable molybdenum by-product output can support revenue diversity when copper production weakens.

For copper, the key issue is the second-quarter recovery. Completion of Los Pelambres maintenance should support stronger output, while improved grades and processing rates at Centinela would be needed to rebuild production momentum.

Antofagasta copper output will therefore depend less on market conditions and more on operational execution in the coming quarters. If maintenance ends smoothly and grades improve, the first quarter may prove to be a temporary low point.

Still, the result reinforces a broader copper supply theme. Global copper demand is increasingly tied to grids, electrification and industrial investment, but mine supply remains vulnerable to operational delays, lower grades and maintenance disruptions.

The Metalnomist Commentary

Antofagasta’s first-quarter decline looks operational rather than structural, but it still matters for copper supply sentiment. The market will watch whether Los Pelambres rebounds after maintenance and whether Centinela can restore grade and processing performance.

Lundin Mining Copper Production Holds Steady as Chilean Assets Drive Record Year

Lundin Mining

Lundin Mining copper production held broadly steady in the fourth quarter of 2025, helping the Canadian miner deliver record full-year copper output. The performance reinforces the strategic importance of Chilean assets in Lundin’s portfolio as global copper producers compete to secure growth in a tightening long-term supply market.

The company produced 331,232t of copper in 2025, placing Lundin Mining copper production in the upper half of its revised guidance range of 319,000-337,000t. The result was supported mainly by strong performance at Candelaria and Caserones in Chile, where higher throughput, better recoveries, and increased cathode production strengthened the group’s operating base.

Lundin Mining copper production also remained stable into the end of the year. Fourth-quarter output reached 87,032t, compared with 84,999t in the third quarter. That stability matters because copper buyers are watching not only new project pipelines, but also the ability of established producers to deliver reliable tonnes from existing assets.

Chilean Operations Strengthen Lundin’s Copper Platform

Candelaria remained Lundin’s largest copper-producing asset in 2025, delivering 145,471t of copper. The operation continues to anchor the company’s near-term supply profile and gives Lundin a strong position in one of the world’s most important copper mining jurisdictions.

Caserones also played a central role in the record year, contributing 132,881t of copper. The asset benefited from higher throughput, improved recoveries, and increased cathode output. It also achieved its highest quarterly production since Lundin acquired the operation in mid-2023, showing that the asset is becoming a more productive part of the group.

Chapada in Brazil added 43,974t of copper during the year, giving Lundin a broader South American production base beyond Chile. Gold production reached 141,859oz in 2025, while nickel production totalled 9,907t. Both were within or above guidance, supporting the company’s wider metals portfolio even as copper remains the core strategic focus.

Stable 2026 Guidance Keeps Focus on Efficiency and Growth

Lundin expects copper production to remain broadly stable at 310,000-335,000t in 2026. This suggests the company is entering the year with a focus on cost optimisation, operating discipline, and asset efficiency rather than a sharp near-term volume expansion.

Nickel output fell to 2,174t in the fourth quarter from 2,724t in the third quarter, but the result remained aligned with operational expectations. Rehabilitation work at Eagle East in the United States helped restore mining and processing rates earlier in the year, supporting a more stable operating base.

Longer term, Lundin’s growth strategy depends on asset optimisation and new project development. Further improvements at Caserones could support incremental copper gains, while the Vicuna project with BHP represents a larger strategic growth pathway. If advanced successfully, these initiatives could strengthen Lundin’s position as a more important copper producer in the global energy transition supply chain.

The Metalnomist Commentary

Lundin’s 2025 performance shows why operational reliability is becoming as valuable as headline growth in copper mining. In a market increasingly defined by permitting delays and project scarcity, stable output from Chilean and Brazilian assets can carry real strategic weight.

Nowa Sol Copper Concentrate Talks Could Link Lumina Metals to KGHM Smelters

Lumina Metals

Nowa Sol copper concentrate could become a new feed source for Poland’s dominant copper producer after Lumina Metals entered talks with KGHM over a potential supply agreement. The companies have signed a preliminary agreement to discuss concentrate supply from Lumina’s Nowa Sol project to KGHM’s copper smelters.

Nowa Sol copper concentrate discussions remain at an early stage. The agreement is not legally binding, but it gives both companies a formal framework to assess volumes, product quality and metallurgical compatibility.

Nowa Sol copper concentrate is strategically important because the project sits inside Poland’s northern copper belt, close to KGHM’s existing copper-silver operations. That location could reduce logistical complexity if the project advances and concentrate proves suitable for KGHM’s smelting system.

The talks also show how European copper producers are looking more closely at regional feedstock options. Copper concentrate availability remains tight globally, and smelters increasingly value nearby, compatible and traceable supply.

KGHM Compatibility Will Decide Commercial Potential

KGHM’s interest will depend on whether Nowa Sol concentrate fits its smelter requirements. Copper concentrate supply is not interchangeable because each smelter has limits around grade, impurities, mineralogy and blending needs.

The preliminary agreement focuses directly on those issues. Lumina and KGHM will evaluate potential volumes, product quality and metallurgical compatibility before any binding offtake structure can emerge.

This matters because smelter feed security is becoming more valuable. Global copper concentrate treatment charges have remained under pressure, reflecting tight mine supply and strong competition among smelters for suitable feed.

For KGHM, a nearby Polish concentrate source could offer strategic advantages if the material meets technical requirements. It could support domestic smelter utilisation and reduce dependence on longer-distance concentrate flows.

For Lumina, a potential supply route to KGHM would strengthen the Nowa Sol project’s commercial pathway. A project located near an established copper producer has a clearer route to market than one that must rely entirely on distant export channels.

Poland’s Copper Belt Gains Strategic Attention

Nowa Sol is Lumina’s flagship underground copper project. It covers a 120km² concession area in Poland’s northern copper belt, a region already associated with copper and silver production.

The project’s location near KGHM’s operations gives it industrial relevance beyond resource potential. Proximity to mining infrastructure, smelting expertise and an established copper workforce can improve development logic if technical and economic studies support the project.

Lumina listed on the Toronto Stock Exchange in April to raise capital for Nowa Sol. The KGHM discussions could help strengthen investor confidence by showing that the project has potential domestic offtake interest.

Poland is already a meaningful copper jurisdiction because of KGHM’s role as the country’s main producer. Any new copper concentrate source inside the same industrial region could support national and European supply security.

The broader market context is also supportive. Copper demand is rising from grids, electrification, renewable energy, data centres and industrial manufacturing, while new mine supply remains difficult to develop.

That makes regional copper projects more strategically valuable. Europe needs not only refined copper, but also mine supply and concentrate flows that can support existing smelting capacity.

The Lumina-KGHM talks are therefore modest in legal status but meaningful in direction. They show how copper supply chains are becoming more regional, technical and security-focused.

The Metalnomist Commentary

The potential Lumina-KGHM deal shows that copper value is increasingly tied to location and smelter fit, not only resource size. If Nowa Sol can deliver compatible concentrate near KGHM’s system, it could become a useful European copper supply asset.

KoBold Mingomba Copper Project Advances as Zambia Targets Major Supply Growth

KoBold Metals

KoBold Mingomba copper project has broken ground in Zambia, moving one of Africa’s largest planned copper mines closer to development. The project is expected to cost more than $2.3bn and produce more than 300,000 t/yr of copper once fully ramped up.

KoBold Mingomba copper project is strategically important because Zambia wants to lift national copper production to about 3mn t/yr by the early 2030s. A project of this scale could become one of the country’s most important new supply sources.

KoBold Mingomba copper project also highlights the growing role of AI-led exploration in critical minerals. KoBold has used proprietary artificial intelligence and machine-learning tools to define a high-grade copper resource deep underground.

The company acquired Mingomba in December 2022. It is now beginning early construction work before completing all engineering studies, with a final cost estimate expected by early next year.

Zambia Copper Investment Gains Momentum

Mingomba could become one of Zambia’s largest copper investments. At more than 300,000 t/yr of planned output, it would rank with some of the largest single copper assets globally.

The project supports Zambia’s wider copper growth strategy. The country is trying to attract large-scale mining investment after years of operational, tax and policy uncertainty.

Other producers are also expanding in Zambia. Barrick and First Quantum are pursuing projects that could help rebuild national output growth.

This matters because copper demand is rising from grids, electric vehicles, renewable energy infrastructure and AI data centres. But new mine supply remains difficult to deliver.

Permitting delays, declining grades and higher capital costs continue to slow global copper development. This gives high-grade, large-scale African projects greater strategic value.

Zambia has a natural advantage because it already has mining infrastructure, workforce experience and established copper export channels. However, execution still depends on policy stability, power supply, transport and downstream processing capacity.

AI Exploration Adds New Dimension to Copper Supply

KoBold’s approach makes Mingomba more than a conventional copper project. The company has built its strategy around using AI and machine learning to analyse geological data and accelerate discovery.

Technology-led exploration is becoming more important as the mining industry searches for deeper, harder-to-find deposits. Many easy copper discoveries have already been developed.

Mingomba’s deep underground resource shows why new exploration methods matter. Future copper supply will increasingly depend on better data, faster targeting and more efficient drilling.

KoBold is backed by major technology and energy-transition investors, including Bill Gates, Jeff Bezos and Sam Altman. That investor base reflects copper’s growing role in electrification and strategic materials policy.

The company is still assessing smelting and refining options for Mingomba’s output. This will be important because mine production alone does not guarantee secure copper supply.

Processing, logistics and offtake structures will determine how Mingomba’s copper enters global markets. Zambia’s ability to capture more value domestically may also shape the project’s long-term impact.

KoBold is also expanding its African critical minerals strategy. It has outlined plans for lithium exploration in the Democratic Republic of Congo by 2027 and is reviewing lithium and nickel opportunities in Namibia. It has also begun early-stage copper exploration in Botswana.

The broader signal is clear. Africa is becoming central to the next phase of copper and critical minerals supply, while technology-led exploration is changing how new deposits are found and financed.

The Metalnomist Commentary

Mingomba is important because it combines scale, grade and timing in a copper market short of credible new supply. If KoBold can convert AI-led discovery into mine execution, Zambia could gain one of the most strategically important copper assets of the next decade.

Copper Price Outlook Strengthens as Strategic Demand Supports $15,000/t Scenario

Traxys

Copper price outlook is shifting into a new regime as traders and miners argue that the metal can reach $15,000/t within the next two to three years. Traxys Group chief executive Mark Kristoff said benchmark copper on the London Metal Exchange could plausibly touch that level over the next 24-36 months.

Copper price outlook is no longer being shaped only by traditional construction cycles, manufacturing indicators and visible inventories. Speakers at the FT Commodities Global Summit in Lausanne said strategic demand, state stockpiling, sulphuric acid risk and artificial intelligence infrastructure are now carrying greater influence.

Copper price outlook has strengthened even though global visible inventories remain high on paper at around 1.9mn-2mn t. Market participants said this reflects a breakdown in the old relationship between warehouse stocks and price, as governments and industrial buyers increasingly treat copper as a policy metal.

The price rally above $13,000/t has aligned with forecasts from major trading houses such as Mercuria. But the more important point is structural: copper is now being priced as a strategic asset tied to electrification, grids, data centres, defence and national industrial policy.

Data Centres and Stockpiling Add a Strategic Premium

Copper’s identity is changing from “Dr Copper” to a policy metal. The old model treated copper as a broad indicator of construction, manufacturing and economic activity. That model is now too narrow.

Data centres and artificial intelligence are becoming major new demand drivers. The next decade could create 2mn-3mn t of additional copper demand from data centres alone. Associated grid reinforcement and power connections could require another 7mn-8mn t.

This demand is not optional. AI infrastructure needs power, cooling, cabling, transformers, substations and grid expansion. Copper sits at the centre of that buildout.

State stockpiling is also changing market behaviour. China’s inventory building and the US strategic push for copper supply are creating demand that does not move like normal industrial consumption.

This helps explain why copper prices remain near historic highs despite weakness in China’s property sector. Around a quarter of China’s copper demand was historically linked to housing, but newer demand channels are offsetting part of that drag.

Electrification, military demand, AI infrastructure and strategic reserves are now becoming more important to price formation. These forces make copper less cyclical than before and more exposed to policy decisions.

The US is also treating copper as a strategic material. Washington is trying to secure domestic and allied supply chains, especially as grid investment, manufacturing reshoring and defence priorities increase copper’s policy value.

Offtake structures are becoming more important in this environment. Copper is increasingly being tied to specific industrial strategies, not just traded as a floating global commodity.

That shift changes where value sits. Traders, miners and governments are no longer competing only for price advantage. They are competing for logistics, location, financing, offtake and control over final destination.

Sulphuric Acid Risk Exposes the Supply Side

The supply side remains the bigger constraint. Major mining groups continue to face falling ore grades, higher capital costs, long permitting timelines and more complex operating conditions.

Average copper grades have declined enough that some producers are processing ore closer to 0.5% copper. That means miners must move, crush and treat much more rock for each tonne of copper produced.

This raises costs and lengthens development timelines. It also makes new supply less responsive to price rallies. Even copper above $13,000/t does not quickly create new mines.

Sulphur and sulphuric acid have become hidden constraints in the copper market. They are especially important for solvent extraction-electrowinning operations in the Democratic Republic of Congo and Chile.

SX-EW production accounts for around 17% of global copper supply. Prolonged sulphuric acid disruption could curtail around 125,000t of DRC output and put around 200,000t of Chilean output at risk in the second half of the year.

This risk matters because the DRC has been one of the most important sources of copper supply growth. Its high grades, flexible project scale and faster development potential make it central to global supply expectations.

However, much of the DRC’s leached copper depends on acid availability. If sulphur or sulphuric acid supply tightens, production costs can rise sharply and some output can become vulnerable.

The risk also hits at a sensitive point in the cycle. The market may show a projected surplus on paper, but that surplus can narrow quickly if input disruptions affect key growth regions.

This is why copper’s current pricing cannot be read only through visible stocks. Inventories may look comfortable, but operational supply chains are more fragile than the headline numbers suggest.

For copper buyers, the lesson is clear. Secure supply now depends on more than exchange access. It depends on geography, processing route, reagents, energy, logistics and policy exposure.

For miners, the opportunity is equally clear. Assets with high grades, reliable acid supply, integrated infrastructure and faster expansion potential will command a strategic premium.

The Metalnomist Commentary

The $15,000/t copper scenario is not only a price forecast; it reflects a new industrial reality. Copper is becoming a strategic bottleneck for AI, grids and electrification, while acid and permitting risks limit how quickly supply can respond.

Vale Copper Production Growth Plan Targets 700,000 t/yr by 2035

Vale

Vale copper production growth is moving into a more ambitious phase as the Brazilian miner targets 700,000 t/yr by 2035. The company produced 382,000t of copper in 2025, beating its guidance of 370,000t. Management now says it aims to nearly double production over the next decade. As a result, Vale copper production growth is becoming a more important part of the global copper supply story.

This matters because large new copper volumes are increasingly difficult to secure. Demand from electrification, grid investment, and industrial expansion continues to support a stronger long-term copper outlook. Vale is positioning itself to capture that growth with a mix of brownfield and regional expansion. Therefore, Vale copper expansion is no longer a secondary objective inside the group.

The company expects an additional 80,000 t/yr of copper capacity to come online by 2029. That near-term increase gives the market a clearer first step before the longer 2035 target. Consequently, Vale copper production growth now has both an immediate and a strategic timeline.

Carajas Copper Projects Will Lead the Next Capacity Increase

Carajas copper projects are expected to play the central role in Vale’s expansion strategy. The Bacaba project in northern Brazil should add 50,000 t/yr of capacity from the second half of 2028. That makes Bacaba one of the most important pillars of the company’s near-term copper plan. As a result, Carajas copper projects are becoming the operational core of Vale copper expansion.

Vale is also advancing the Coarse Particle Flotation project at the Salobo complex. That initiative is expected to add another 30,000 t/yr of capacity. Together, Bacaba and Salobo account for the full 80,000 t/yr increase expected by 2029. Therefore, Vale copper production growth is being built on identifiable projects rather than distant ambition alone.

The Alemao project could add further upside later. Vale is still seeking permits to advance that development in the Carajas region. Meanwhile, the company is clearly using Carajas as the center of its long-term copper buildout.

Vale Copper Expansion Comes Alongside Broader Base Metals Growth

Vale copper expansion is also part of a wider base metals push across the portfolio. The company expects nickel output to rise through the ramp-up of the Voisey’s Bay mine extension and full operation of the second furnace at Onca Puma. That means copper growth is happening alongside stronger nickel ambitions. As a result, Vale is reinforcing its position in metals tied to electrification and industrial transition.

The company also plans to lift throughput at the Sudbury basin in Canada to 7mn t/yr from 5mn t/yr over the coming years. While no specific timeline was given, the direction is clear. Vale wants more scale across its base metals assets. Consequently, Vale copper production growth should be viewed as part of a broader strategic reshaping of the company.

This wider context matters because copper growth alone does not define long-term competitiveness. Producers that can expand several critical metals at once may gain stronger relevance in global supply chains. Therefore, Vale copper expansion looks even more important when placed inside its larger base metals strategy.

The Metalnomist Commentary

Vale’s copper target matters because it combines delivered outperformance with a credible expansion path in Carajas. The most important point is not just the 2035 target. It is that Vale already has the first building blocks in place to move meaningfully toward it. If execution stays on track, Vale could become a much stronger force in global copper supply over the next decade.
