Gunnison Copper first cathode production boosts US copper supply ambitions

Gunnison Copper

Gunnison Copper first cathode production marks a key milestone for US domestic copper supply. The company produced its first copper cathode at the Johnson Camp Mine in Arizona in late August, ahead of schedule. As a result, the Gunnison Copper first cathode production strengthens US efforts to secure critical minerals for energy transition.

Early ramp-up at Johnson Camp Mine underpins new US copper source

Gunnison Copper first cathode production follows the successful start of solvent extraction and electrowinning operations. The company began running its SX plant and EW circuit in August, using run-of-mine ore from the Arizona site. Therefore, the project now moves from development into early ramp-up, which often proves pivotal for leaching projects.

The company expects to produce 25mn lbs per year of copper cathode, equal to about 11,300 tonnes. This scale does not rival major Chilean or Peruvian mines, yet it still matters for US niche supply. Meanwhile, the focus on finished cathode production rather than concentrates aligns with growing demand from North American smelters and fabricators.

Funding support highlights the broader strategic value of this new copper stream. The Johnson Camp Mine received backing from Nuton, a Rio Tinto venture focused on innovative copper technologies. In addition, the project secured $13.9mn in US Department of Energy tax credits in January to support domestic copper production.

Strategic context for US energy transition and critical minerals policy

The Gunnison Copper first cathode production arrives as policymakers push for more resilient US copper supply chains. Copper demand continues to rise across electric vehicles, renewable power and grid upgrades. Therefore, new SX–EW operations like Johnson Camp help reduce dependence on imported copper units.

Federal tax credits signal Washington’s willingness to support qualifying critical mineral projects. As a result, projects such as Johnson Camp can de-risk early capital phases and accelerate commissioning schedules. However, Gunnison Copper must still deliver consistent production performance, maintain environmental compliance and manage operating costs in Arizona’s competitive mining landscape.

For investors and copper buyers, the project offers modest but meaningful additional US cathode volumes. It may also showcase Nuton and Rio Tinto’s broader technology and partnership model for brownfield and mid-scale assets. Over time, similar projects could play a larger role in regional copper balance and contract pricing dynamics.

The Metalnomist Commentary

Gunnison Copper’s first cathode production at Johnson Camp illustrates how smaller US projects can still punch above their weight in policy terms. While volumes remain limited, the combination of Nuton funding and DOE tax support shows how technology and incentives now shape copper growth. Market participants should watch ramp-up performance closely, since SX–EW reliability will determine whether this asset becomes a durable pillar of US cathode supply.

Taseko Florence Copper Project Begins Cathode Production in Arizona

Taseko Mines Florence

Taseko Florence Copper project has reached a major milestone with the start of copper cathode production in Arizona. The company said production began earlier this week and expects its first cathode harvest within days. It also expects 30-35mn lbs of copper output from the Florence Copper project this year. As a result, Taseko Florence Copper project is moving from construction into commercial production.

This matters because the Florence Copper project gives Taseko a new source of Arizona copper cathode at a time when US copper supply remains strategically important. The company had already signaled in January that production was close after construction finished in the fourth quarter. Now the project has entered its next phase with actual cathode output. Therefore, Taseko Florence Copper project is becoming one of the more important near-term US copper ramp-ups.

Florence Copper Project Ramp-Up Now Depends on Wellfield Expansion

Florence Copper project still has more work ahead before reaching full production capacity. Taseko said it must expand wellfield operations to continue ramping output. The company currently has three drill rigs at the site and will add a fourth rig within the next week. As a result, the pace of wellfield expansion will directly shape how quickly the Florence Copper project reaches full operating potential.

This is important because early production milestones often attract attention, but ramp-up execution determines the project’s real long-term value. A smooth wellfield expansion would improve confidence in the company’s operating plan. However, delays could slow the path toward higher Arizona copper cathode volumes. Meanwhile, the current 2025 guidance gives the market a clear first benchmark for performance.

Taseko Copper Production Gains Support Beyond Florence

Taseko copper production is also expected to improve beyond Arizona. The company expects output at its Gibraltar mine in British Columbia to rise to 110-115mn lbs in 2026 from 98mn lbs in 2025. Gibraltar also produced 2.2mn lbs of copper cathode last year. Therefore, Taseko copper production is being supported by both a new US project and a stronger Canadian base.

The broader financial picture remains mixed. Taseko reported an annual loss in 2025, although it returned to quarterly profit in the fourth quarter. That makes the Florence Copper project even more important to the company’s growth story. Consequently, stronger production from Florence and Gibraltar could become central to improving financial performance over the next year.

The Metalnomist Commentary

This start-up matters because Florence is no longer a development promise. It is now a producing copper asset with clear near-term output targets. If Taseko manages the wellfield ramp-up effectively, Florence could become a more meaningful part of the North American copper supply story.

Aurubis Reports Increase in Copper Cathode Output for Q4 2024

Aurubis

Copper Concentrate Throughput Declines, but Recycling and Cathode Production Rise

Aurubis, Europe’s largest copper producer and recycler, reported a positive performance in copper cathode and recycled cathode production for the fourth quarter of 2024. However, the company also saw a decrease in copper concentrate throughput during the same period, reflecting some challenges in its operations.

Growth in Copper Cathode and Recycled Cathode Production

In the October-December period of 2024, Aurubis produced 152,000 tonnes of copper cathode, marking a 1% increase from the previous year. This output consisted of 95,000 tonnes from its Hamburg plant in Germany and 57,000 tonnes from its Pirdop site in Bulgaria. The increase in production reflects Aurubis’ strong operational performance in copper cathode production.

Aurubis also reported a 4% increase in recycled cathode output, which reached 130,000 tonnes in Q4 2024. This growth was driven by higher production at its Lunen site in Germany, which saw a 27% increase in recycled cathode output. Lunen’s output reached 42,000 tonnes, supported by higher tankhouse capacity. The company’s Beerse and Olen sites in Belgium also contributed 6,000 tonnes and 82,000 tonnes, respectively, to the overall recycling output.

Decline in Copper Concentrate Throughput

On the downside, Aurubis experienced a 7% decrease in copper concentrate throughput in the fourth quarter, amounting to 601,000 tonnes. The decrease was largely attributed to a 13% reduction in production at the Hamburg site, which produced 261,000 tonnes. Despite the decline, the company’s overall performance remained strong due to the rise in copper cathode and recycled cathode output.

Aurubis also saw a significant improvement in its financial results, with operating profit before tax increasing by 17% to €130 million ($135 million). This was attributed to higher metal results and stronger earnings from its copper products, reinforcing the company’s strong position in the copper market.

CMOC Copper Output Rose in 2025 on Stronger DRC Production

Copper Wire

CMOC copper output increased in 2025 as the Chinese diversified metals producer lifted production from its copper-cobalt operations in the Democratic Republic of Congo. The company produced 741,100t of copper during the year, up 14% from 2024.

The increase was driven by higher output from both the Tenke Fungurume copper-cobalt mine and the Kisanfu copper-cobalt mine. These assets remain central to CMOC’s copper growth strategy and to China’s access to African copper cathode supply.

CMOC copper output is expected to rise again in 2026, with the company targeting production of 760,000-820,000t. CMOC also plans to expand copper production at Kisanfu by another 100,000 t/yr in 2027.

DRC Assets Strengthen CMOC’s Copper Growth Platform

CMOC’s production growth reinforces the strategic importance of the DRC in global copper supply. The country has become one of the most important sources of copper cathode for China, supported by large-scale mining, solvent extraction and electrowinning capacity.

Tenke Fungurume remains a key asset in this system. The mine has copper cathode capacity of 270,000 t/yr, and its TFM-1 copper cathode brand was approved by the London Metal Exchange for listing on 27 March.

The LME approval strengthens the marketability of CMOC’s DRC-produced copper. Exchange-listed status can improve brand recognition, liquidity and acceptance among global buyers, especially in refined copper markets where cathode quality and deliverability matter.

China’s Copper Supply Chain Leans Heavily on DRC Cathode

The DRC remained China’s largest source of copper cathode imports in 2025. China imported 1.44mn t of copper cathode from the country, accounting for 37.6% of total imports.

This trade flow highlights the depth of China’s dependence on DRC copper supply. As domestic demand from grids, manufacturing, electric vehicles and energy infrastructure continues, stable access to DRC cathode remains strategically important.

CMOC copper output growth also has wider market implications. Additional production from Tenke Fungurume and Kisanfu can help offset disruptions in other copper regions, but it also increases the role of African supply in balancing global refined copper markets.

The Metalnomist Commentary

CMOC’s 2025 copper growth shows how the DRC has become a core pillar of China’s refined copper security. The next strategic question is whether rising African cathode supply can remain reliable amid infrastructure, policy and geopolitical risks.

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.

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.

CMOC Copper Output Rises as DRC Mines Strengthen China Supply

CMOC

CMOC copper output increased in the first quarter of 2026 as higher production from the company’s Democratic Republic of Congo copper-cobalt mines lifted supply. The Chinese diversified metals producer produced 187,880t of copper in January-March, up 10% from a year earlier.

CMOC copper output was supported by stronger production at the Tenke Fungurume and Kisanfu mines. These assets are central to China’s copper and cobalt feedstock security because they supply large volumes of cathode and intermediate material from one of the world’s most important copper-cobalt districts.

CMOC copper output is expected to remain a major market focus this year. The company is targeting 760,000-820,000t of copper production in 2026, after producing 741,100t in 2025.

The result reinforces the DRC’s role as China’s largest imported copper cathode source. China imported 275,359t of copper cathode from the DRC in the first quarter, equal to 37.5% of total imports.

Tenke and Kisanfu Anchor CMOC’s Copper Growth

CMOC’s first-quarter copper growth reflects the scale and strategic importance of its DRC operations. Tenke Fungurume and Kisanfu remain core assets for the company’s copper-cobalt portfolio.

The company plans to expand output at Kisanfu by adding 100,000 t/yr of copper cathode capacity. Completion is targeted for 2027.

The expansion could also lift cobalt capacity. CMOC has not disclosed the planned increase, but market participants expect Kisanfu’s cobalt capacity to rise by more than 30,000 t/yr.

This matters because copper and cobalt are increasingly linked in DRC project economics. Higher copper output can bring additional cobalt units into the market, depending on ore composition, processing rates and export rules.

The London Metal Exchange approval of CMOC’s TFM-1 copper cathode brand adds another layer of market significance. The brand, produced at Tenke Fungurume, was approved for listing on 27 March and has a registered production capacity of 270,000 t/yr.

Exchange approval improves brand visibility and market acceptance. It can also support trade liquidity, financing and customer confidence for DRC-origin copper cathode.
China’s copper cathode import structure shows why this is important. The DRC already supplies more than one-third of China’s imported cathode, making Congolese supply critical to Chinese refined copper availability.

The China grade-A copper cathode premium was steady at $55-70/t cif Shanghai on 23 April. The range narrowed from $55-75/t a week earlier, showing a relatively stable but cautious spot market.

Cobalt Output Stays Flat as Quotas Restrict Feedstock Flows

CMOC’s cobalt production was largely unchanged in the first quarter. The company produced 30,508t of cobalt, up only 0.3% from a year earlier.

The company set its 2026 cobalt output guidance at 100,000-120,000t. That is broadly stable against 117,549t produced in 2025.

The flat cobalt outlook reflects a more complicated market. The DRC suspended cobalt feedstock exports from 22 February to 15 October 2025 before moving to a quota-based export system for the fourth quarter of 2025 and for 2026-27.

Administrative delays have slowed the quota system. The DRC extended fourth-quarter 2025 quotas to 31 March 2026 because of slow processing.

The effect on Chinese imports has been severe. China imported only 1,278t cobalt metal equivalent of cobalt intermediate feedstock in January-February, down 96% from a year earlier.

Cobalt hydroxide prices remained stable at $25.95-26.10/lb cif China on 23 April. But the stability masks a market still shaped by restricted DRC export flows, delayed allocations and uncertainty over quota administration.

For CMOC, the copper side of the portfolio is showing clear growth. The cobalt side remains more exposed to policy risk, export controls and administrative timing in the DRC.

The Kisanfu expansion could increase future cobalt availability, but the market impact will depend on whether DRC export rules allow material to move smoothly to downstream refiners.

The Metalnomist Commentary

CMOC’s first-quarter results show that DRC copper remains essential to China’s refined copper supply, while cobalt is increasingly constrained by policy rather than production alone. The strategic issue is no longer just mine output, but whether export quotas, brand approvals and logistics can keep critical metal flows moving.

China's Jiayuan to Secure Copper Cathode Supply from Swiss Firm IXM for Lithium-Ion Foil Production

Guangdong Jiayuan

Guangdong Jiayuan, a leading Chinese copper foil producer, has reached an agreement with Switzerland-based trading firm IXM to purchase a significant quantity of copper cathode feedstock. The deal, valued at approximately 5.066 billion yuan ($694 million), is set to support Jiayuan’s expansion of refined copper foil production, which is critical for lithium-ion batteries, copper-clad laminates, and printed circuit boards.

Details of the Copper Cathode Purchase Agreement

The agreement between Jiayuan and IXM will see the Chinese company secure 60,000 tons of copper cathode from IXM’s Geneva operations between December 2024 and November 2025. Additionally, Jiayuan will purchase 10,000 tons of cathode from IXM’s Shanghai branch during 2025. The price of the copper cathode will be determined through a negotiated pricing methodology, which will be finalized when both parties sign the contract.

Jiayuan, with a production capacity of 100,000 tons per year of refined copper foil, has seen steady growth in its production. In the first half of 2024, the company produced 24,000 tons of copper foil, marking a slight increase of 0.1% year-over-year. This agreement will ensure a steady supply of high-quality copper cathode to meet the growing demand for copper foil in key sectors such as electric vehicle (EV) batteries and electronic components.

China's Booming Copper Foil and NEV Industries

China’s refined copper foil production capacity reached 1.6 million tons per year in 2023, a 51% increase from the previous year. Notably, the production capacity for lithium-ion copper foil—used in batteries for electric vehicles—rose sharply by 68%, reaching 950,000 tons per year in 2023. With China’s new energy vehicle (NEV) market expanding rapidly, the demand for lithium-ion copper foil is expected to grow significantly. Industry experts predict that deliveries of lithium-ion copper foil in China will reach 1.1 million tons per year by 2025.

The Chinese NEV industry is experiencing robust growth, with production rising by 35% to 11.345 million units in the first 11 months of 2024. Sales of NEVs have also surged, increasing by 36% over the same period. As the NEV market continues to expand, the demand for copper, particularly copper foil for lithium-ion batteries, is expected to increase, further driving the need for stable copper supply agreements like the one between Jiayuan and IXM.

Copper Market Trends and Prices

On December 12, 2024, Metalnomist-assessed grade-A copper cathode prices, based on the London Metal Exchange (LME) official cash prices, were in the range of $40-60 per ton cif Shanghai. These prices remained flat compared to December 10, but they had dropped from the previous range of $45-60 per ton observed on December 5 due to a rebound in copper prices during the week. The fluctuating prices highlight the importance of securing stable supply contracts for manufacturers like Jiayuan as copper remains a critical commodity in the transition to a low-carbon economy.

Aurubis Sees Slight Decline in Copper Cathode Production Amid Maintenance and Expansion Efforts

Aurubis, Europe's largest copper producer and recycler, reported a slight decrease in copper cathode production during the first nine months of its fiscal year, driven primarily by a downturn in its recycling division. The Hamburg-based company announced on Friday that it produced 838,000 tons of copper cathode between October and June, marking a 0.4% decline from the same period last year.

The drop in production is largely attributed to a 2% year-on-year decrease in output from Aurubis' recycling division, which managed 383,000 tons of copper cathode during this period. The decline was most pronounced at the company's Lunen facility in Germany, where production fell by 6% to 111,000 tons due to maintenance work carried out early in the fiscal year.

However, the recycling division saw a rebound in the April to June quarter, with output increasing by 4% compared to the previous quarter. This recovery was bolstered by a 14% surge in production at the Lunen plant following the completion of a tankhouse refurbishment in June, which has increased the plant's annual copper cathode capacity by 10% to 210,000 tons.

Aurubis operates three recycling plants that produce copper cathode from scrap: Beerse and Olen in Belgium, and Lunen in Germany. While Lunen saw a slight dip earlier in the year, output from the Beerse and Olen facilities remained largely stable, mitigating the overall impact on the company's recycling output.

In contrast, Aurubis' smelting division experienced a modest growth in copper cathode production, with a 1% increase year-on-year to 455,000 tons. The Hamburg plant contributed 284,000 tons, while the Pirdop site in Bulgaria added 171,000 tons. The division's overall stability highlights the continued robust demand for copper in Europe, even as the global market faces fluctuating dynamics.

Aurubis also reported a 2% increase in concentrate throughput at its primary smelters, reaching 1.74 million tons. This was largely driven by a 15% surge in throughput at the Pirdop site, which offset a 12% decline at the Hamburg facility. The company is currently expanding the tankhouse at its Pirdop plant, a project that began in April and is expected to boost the site's refined copper output by 50% to 340,000 tons per year by the second half of 2026.

Looking ahead, Aurubis expressed confidence in maintaining stable demand for copper cathodes for the remainder of the fiscal year, supported by ongoing expansion efforts and the completion of key maintenance projects.

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.

Taseko Florence Copper Project Starts Cathode Ramp-Up in Arizona

Taseko

Taseko Florence copper project has started producing copper cathode in Arizona, giving Canadian producer Taseko Mines its first commercial metal from the US in-situ copper development. The project’s solvent extraction and electrowinning plant started operations in mid-February and produced 1.5mn lb, or about 680t, of copper cathode in the first quarter.

The Taseko Florence copper project is important because it uses in-situ copper recovery rather than conventional open-pit mining. The process leaches copper underground and recovers it through solution flows before producing cathode through solvent extraction and electrowinning.

The Taseko Florence copper project offers a different supply model for the US copper market. It can reduce upfront capital intensity compared with traditional mining, but it depends on careful control of underground leaching, solution movement, grades and environmental performance.

Taseko previously targeted 40mn-50mn lb of copper output from Florence in 2026. The company expects production to rise to 80mn lb in 2027 as the project moves through ramp-up.

Florence Adds US Cathode Capacity With Lower Mining Intensity

Florence’s first cathode production marks a key operational step for Taseko. The project is now moving from construction and commissioning into the early stage of commercial production.

The in-situ recovery model gives Florence strategic relevance. It avoids large-scale excavation and instead relies on controlled leaching below ground, which can reduce surface disturbance and capital needs.

However, the method also requires disciplined technical execution. Operators must manage solution chemistry, wellfield performance, recovery rates and environmental controls to ensure the process remains stable.

Florence’s output will come as refined copper demand becomes increasingly tied to electrification, grid investment, data centres, electric vehicles and domestic manufacturing. US cathode supply is strategically important because refined copper availability affects wire, cable, power equipment and industrial users.

The project’s cost exposure also looks partly protected in the near term. Taseko said Florence will not face the sharp recent rise in sulphuric acid prices because its acid supply is locked under a fixed-price contract for this year.

That protection matters. Sulphuric acid has become a more sensitive cost input for copper leaching operations because Middle East disruption and tighter sulphur flows have lifted market concerns. A fixed-price contract gives Florence more cost visibility during its early ramp-up.

Gibraltar Output Jumps as Diesel Costs Add Pressure

Taseko’s established Gibraltar mine in British Columbia also delivered a stronger first quarter. Copper output rose to 30mn lb, or about 13,600t, up 50% from a year earlier.

The increase was supported by steadier grades and better recoveries. This suggests Gibraltar benefited from improved operating performance rather than only stronger throughput.

Molybdenum output also rose sharply. Gibraltar produced 717,000 lb, or about 325t, of molybdenum in the first quarter, up 113% from a year earlier.

Molybdenum by-product output can improve mine economics because it adds revenue beyond copper. It also links Gibraltar to special steel, stainless steel, energy equipment and high-strength alloy demand.

Sales lagged production slightly because of shipping timing. This means some of the production benefit may flow through later, depending on shipment schedules and realized prices.

Cost pressure remains a risk. Taseko said higher diesel prices could add 10-15¢/lb to Gibraltar costs this year, equivalent to about $220-330/t.

Diesel exposure is important for open-pit mines because haulage, mobile equipment and site logistics rely heavily on fuel. If energy prices remain elevated, Gibraltar’s operating costs could rise even as production performance improves.

Taseko’s first-quarter update therefore shows two different copper stories. Florence is entering ramp-up as a new US cathode asset with fixed acid pricing, while Gibraltar is producing more copper and molybdenum but faces higher fuel-cost risk.

The Metalnomist Commentary

Taseko’s update shows how copper supply growth is increasingly tied to project type and cost exposure. Florence offers a lower-mining-intensity US cathode route, while Gibraltar highlights the continuing importance of grade, recovery and diesel costs in conventional copper mining.

Boliden’s 2024 Output Shows Mixed Performance in Zinc and Nickel Production

Boliden

Zinc Production Declines, But Copper and Nickel Output Increase for Sweden's Boliden

Sweden-based mining company Boliden has reported mixed results for its 2024 production across various metals. Zinc output showed a notable decline, while copper and nickel production saw significant increases. This reflects both challenges and successes in the company’s operations, driven by factors such as environmental restrictions and planned maintenance.

Zinc Production Declines, While Copper and Nickel Perform Well

Boliden's zinc-in-concentrate production increased by 8% in the fourth quarter of 2024, reaching 41,680 tonnes. However, the company’s full-year zinc output fell by 16%, totaling 164,108 tonnes, attributed to limited production at the Swedish Garpenberg mine due to environmental permit restrictions. Additionally, maintenance work at the Swedish Boliden Area mine further impacted overall zinc output.

Despite the drop in zinc production, the company managed a 7% increase in zinc production in the fourth quarter, reaching 112,692 tonnes. For the full year, Boliden's total zinc output dropped by just 1% to 453,743 tonnes, a relatively small decrease considering the challenges faced.

Copper and Nickel Show Strong Growth

Boliden reported a 7% increase in its copper-in-concentrate production for Q4 2024, reaching 22,326 tonnes. This brought the total copper-in-concentrate output for the year to 90,692 tonnes, a 1% increase from 2023. However, copper cathode production saw a drop of 29% for the full year, totaling 158,968 tonnes, due to the suspension of cathode production at Sweden's Ronnskar smelter.

On the other hand, copper anode production rose by 6% in Q4, reaching 120,856 tonnes, and the total annual output increased by 11% to 433,778 tonnes. This was supported by higher output at the Ronnskar smelter in the fourth quarter.

Nickel production was one of the standout performers. Boliden’s nickel-in-concentrate output increased by 11% in Q4, reaching 2,849 tonnes. For the full year, nickel production surged by 16% to 11,529 tonnes, driven by higher recovery rates at Finland's Kevitsa mine. Additionally, nickel-in-matte production for the fourth quarter rose by 6%, totaling 11,715 tonnes. Annual nickel-in-matte production increased by 17% to 40,074 tonnes.

Boliden’s Outlook for 2025

While Boliden faced challenges with its zinc production, the company’s increased copper and nickel output in 2024 demonstrates its ability to adapt and meet growing global demand for these critical metals. The strong performance in copper and nickel, alongside ongoing operational improvements, positions Boliden to continue making significant contributions to the global mining sector in 2025.

Taseko copper guidance cut again as Gibraltar underperforms

Taseko

Taseko copper guidance cut for 2025 highlights the strain at its Gibraltar mine in British Columbia. Taseko copper guidance cut by 11pc shows how earlier operational shortfalls still weigh on full-year output expectations. As a result, Taseko copper guidance cut underscores the growing importance of new production from Florence Copper in Arizona.

Gibraltar struggles to regain copper momentum

Taseko now expects 2025 copper production of 100mn–105mn lbs, including cathode output. This latest Taseko copper guidance cut follows weaker-than-planned performance earlier in the year. The company admits it cannot fully recover the production shortfall created by low recoveries in the first quarter.

However, third-quarter copper production edged up by 2pc to 27.6mn lbs, including 900,000lbs of cathode. Second-quarter output slipped to 19.8mn lbs, down from 20.2mn lbs a year earlier. The company sold 26.3mn lbs of copper in the third quarter, flat year on year, indicating that sales have not yet reflected meaningful growth.

Meanwhile, by-product performance improved, with molybdenum production up 33pc on the year to 560,000lbs. This helps unit costs but cannot fully offset the impact of lower-than-guided copper volumes. Taseko still expects a “significant” fourth-quarter copper production increase, but the lowered guidance shows that recovery will be partial at best.

Florence Copper steps up as future growth driver

The guidance reset increases pressure on the Florence Copper project to deliver new volumes. Taseko has started wellfield operations at Florence after receiving final regulatory approvals, marking a key de-risking milestone. The company expects first copper cathode from Florence in about three months, adding a second production base.

As a result, Florence Copper could gradually rebalance the group’s portfolio away from relying solely on Gibraltar. In-situ leach cathode production should also help diversify cost structures and reduce exposure to Gibraltar’s recovery volatility. Over time, the combination of Gibraltar concentrate and Florence cathode can strengthen Taseko’s position in the North American copper market.

The Metalnomist Commentary

Taseko’s trimmed outlook shows how fragile single-asset copper stories can be when recoveries slip. The speed and reliability of the Florence Copper ramp-up will likely define investor confidence far more than short-term Gibraltar variability. If Florence delivers on schedule, the current guidance cut may be remembered as a temporary stumble rather than a structural setback.

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.

Hudbay ASCU Acquisition Builds Larger Arizona Copper Growth Platform

Hudbay Arizona Copper

Hudbay ASCU acquisition plans will give Hudbay Minerals full control of the Cactus copper project in Arizona and create a larger copper growth platform in the US southwest. The all-share transaction is valued at about C$1.5bn and will add Cactus to Hudbay’s existing Copper World development.

Hudbay already owns just under 10pc of Arizona Sonoran Copper Company and will acquire the remaining shares through the deal. The transaction is expected to close in the second quarter of 2026, subject to required approvals and closing conditions.

Hudbay ASCU acquisition strategy is built around scale, timing, and operating synergies. By combining Copper World and Cactus, Hudbay says it will control the third-largest copper district in North America, positioning the company for a major production increase by 2030.

Arizona Projects Could Double Hudbay’s Copper Output

Hudbay expects staged development of Copper World and Cactus to lift total annual copper production from around 125,000t today to more than 250,000t by 2030. Combined output could exceed 350,000 t/yr once Cactus reaches full development.

Copper World is expected to produce around 92,000 t/yr of copper by 2030. Cactus is expected to add about 103,000 t/yr at steady state, giving Hudbay a second major Arizona production pillar.

Both projects are expected to produce copper cathode. This matters because cathode production provides direct refined copper units for wire, electrical infrastructure, construction, industrial equipment, and energy transition supply chains.

Cactus and Copper World Create Operational Synergy

Hudbay ASCU acquisition plans also carry practical operating benefits. The company expects the two Arizona projects to share construction teams, which could improve execution and reduce duplication during development.

Sulfuric acid supply is another key synergy. Hudbay expects Copper World to provide sulfuric acid for oxide leaching at Cactus, linking the two assets within a more integrated regional operating model.

The company also expects $5mn-10mn/yr in corporate cost savings. While the figure is modest compared with the project value, the larger strategic benefit comes from consolidating land, infrastructure, construction planning, and future copper output in one district.

The Metalnomist Commentary

Hudbay’s ASCU deal shows how copper developers are using consolidation to build scale before the next supply deficit tightens. Arizona’s value lies not only in resource size, but in the ability to create integrated cathode production near major North American demand centers.

Boliden Zinc and Copper Output Rises After Lundin Mine Acquisitions

Swedish Boliden

Boliden zinc and copper output increased in the first quarter as the Swedish mining and smelting group benefited from the 2025 acquisitions of Somincor in Portugal and Zinkgruvan in Sweden. The additions lifted concentrate production sharply from a year earlier, although operational disruptions limited quarter-on-quarter momentum.

Boliden zinc and copper output growth was strongest on a year-on-year basis. Zinc-in-concentrate production rose by 54% to 89,200t, while copper-in-concentrate output increased by 53% to 28,824t.

Boliden zinc and copper output still faced several short-term constraints. Seismic activity halted operations at Garpenberg in Sweden, poor ground conditions weighed on Tara in Ireland, and heavy rainfall affected Somincor in Portugal.

The first-quarter result shows the impact of Boliden’s larger asset base. Acquisitions increased scale, but operational reliability, grade control and smelter performance remain central to the company’s 2026 metals outlook.

Zinc Growth Masks Garpenberg and Tara Disruption

Boliden’s zinc-in-concentrate output rose strongly from a year earlier because Somincor and Zinkgruvan added new mine volumes. However, production fell by 3% from the previous quarter, showing that acquired capacity did not fully offset operational headwinds.

Tara produced 17,413t of zinc-in-concentrate, down 19% from a year earlier. Poor ground conditions and other operational challenges weighed on the Irish mine.

Garpenberg output fell by 22% to 19,329t after seismic activity disrupted operations in mid-March. Boliden expects production to resume gradually in the second quarter, but the disruption has materially reduced the site’s 2026 outlook.

The company now expects Garpenberg milled volumes of around 1.5mn t in 2026, down from previous guidance of 3.7mn t. It forecasts 2.3mn t of milled volumes in 2027 and lowered Garpenberg’s zinc grade guidance to 2.7% from 2.9%.

Refined zinc production also weakened. Output fell by 2% on the year to 107,931t, mainly because production at Odda in Norway dropped by 19%.

Odda’s performance was affected by two unplanned roaster stoppages and the delayed start-up of another roaster. The decline shows how smelter reliability can offset stronger mine-side additions.

The zinc market backdrop remains tight in concentrate terms. Global refined zinc demand fell by 7% from the previous quarter because of seasonal patterns, but was unchanged from a year earlier. Global zinc concentrate production rose by 4% year on year, while spot treatment charges fell from $35/t to $0/t during the quarter.

Falling treatment charges are important for zinc smelters and miners. They indicate that concentrate availability remains tight relative to smelter demand, shifting bargaining power toward miners with available feedstock.

Copper Concentrate Tightness Supports Strategic Value

Boliden’s copper-in-concentrate output rose by 53% from a year earlier to 28,824t. The increase was mainly driven by the addition of Somincor and Zinkgruvan.

Quarter-on-quarter copper output slipped by 3% from 29,690t. Boliden attributed the decline mainly to slightly lower copper grades at Aitik and lower production at Somincor.

Aitik remained the company’s core copper asset. Milled volumes were 9.8mn t, broadly in line with a year earlier, but lower copper grades weighed on output.

However, Aitik showed operational strengths. Boliden reported high mining rates and better recoveries than in the first quarter of 2025 because of less oxidised ore.

At the smelter level, copper cathode production rose by 12% on the year to 41,567t, although it fell by 2% from the previous quarter. Harjavalta performed better than a year earlier, when strikes in Finland and a lack of suitable concentrates weighed on operations.

Casted copper anode production rose by 4% year on year to 107,714t. This supports Boliden’s integrated copper position, linking mine output with smelting and refining capacity.

Boliden also highlighted tightening copper concentrate conditions. Global refined copper consumption fell by 10% from the previous quarter and by 1% from a year earlier, but concentrate production was stable quarter on quarter.

Spot treatment charges continued to fall, and Chinese benchmark contracts settled at zero treatment and refining charges. This underlines structural tightness in the copper concentrate market, even when refined demand indicators are mixed.

Nickel output was mixed. Nickel-in-concentrate production rose by 20% on the year to 3,282t and increased by 30% from the fourth quarter, supported by higher grades at Kevitsa.

Refined nickel performance moved lower. Nickel-in-matte production at Harjavalta fell by 17% on the year to 8,425t because of an unfavourable feed mix and higher pyrite consumption.

Boliden left 2026 guidance unchanged for all mines except Garpenberg. That means the main revision affects zinc and silver more than copper or nickel.

The Metalnomist Commentary

Boliden’s quarter shows how acquisitions can lift headline production while operational risks still shape real supply. The sharper signal is in treatment charges: zinc and copper concentrate markets remain tight enough that mine reliability and smelter feed quality now carry strategic value.

Chile Copper Production Falls as Mature Mines and Acid Costs Pressure Supply

Chile Copper minnig

Chile copper production fell sharply in the first quarter, deepening concerns over near-term supply from the world’s largest copper-producing country. Output declined by 5.8% year on year to 1.217mn t.

Chile copper production weakness was driven by lower output from mature mines, softer grades and weaker refined cathode production. March was especially weak, with national copper output down 9% from a year earlier.

Chile copper production matters because the global copper market is already facing tight concentrate availability, fragile refined flows and stronger demand from grids, electrification and data centres.

The decline reinforces a core market concern. Higher copper prices are not quickly translating into higher mine output, especially in countries where ageing assets and delayed projects continue to limit supply response.

Concentrate Output Falls as Major Mines Underperform

Chile’s copper concentrate output fell by 6% year on year to around 947,000t in the first quarter. Concentrates accounted for almost 78% of the country’s total mine output.

The weakness was visible across both state-owned and private producers. Escondida remained Chile’s largest copper mine with 311,600t in the quarter, followed by Codelco at 299,600t, including stakes in El Abra and Anglo American Sur.

Codelco’s own divisions produced around 271,600t. The company is targeting 1.344mn t this year after producing about 1.33mn t in 2025.

The first-quarter result keeps pressure on Codelco to stabilise output after several years of structural underperformance. Ageing mines, delayed projects and higher operating costs remain key constraints.

March data showed broad weakness at the largest mines. Codelco output fell by nearly 10% year on year to 110,900t, while Escondida declined by almost 16% to 101,600t.

Collahuasi, jointly owned by Glencore and Anglo American, produced 31,400t in March, down 10.8% from a year earlier. Its first-quarter output totalled 88,200t.

Other major producers also faced pressure. Los Pelambres produced 69,600t, Anglo American Sur 58,200t, Quebrada Blanca 55,500t and Spence 44,600t during the quarter.

Antofagasta produced 143,000t of copper in the quarter. The company cited lower processing rates and weaker grades at Los Pelambres and Centinela concentrates.

Teck’s Quebrada Blanca was one of the more stable performers. The mine produced 55,500t despite planned maintenance and a shorter February, supported by stronger March throughput and recoveries.

SX-EW Cathode Weakness Exposes Chile to Acid and Fuel Costs

Chile’s refined SX-EW cathode output reached 269,300t in the first quarter. January output increased, but February and March both fell from a year earlier.

Refined electrolytic cathode output was weaker at 107,000t. March production fell by 38.7% year on year, pulling total refined cathode output to about 376,300t.

This matters because Chile’s oxide and SX-EW operations are increasingly exposed to sulphuric acid availability and pricing. Acid is a reagent cost for leaching operations.

Smelters can benefit from higher sulphuric acid prices when they sell acid as a by-product. SX-EW producers face the opposite exposure, as higher acid costs directly pressure operating margins.

Higher diesel prices are adding to the problem. Codelco said Middle East-related cost increases lifted its cash cost by at least 10¢/lb.

Antucoya also showed the cost pressure. Output weakened, while costs rose by 23% year on year to $3.03/lb on higher sulphuric acid and diesel prices.

Chile’s investment pipeline remains significant but long-dated. Freeport-McMoRan has started environmental permitting for a $7.5bn expansion of El Abra.

The project aims to lift production to around 300,000 t/yr from 91,400t in 2025. But it requires a new concentrator and desalination plant and is not expected to start until the next decade.

That timing is critical for the market. Chile has projects, but they will not solve immediate supply tightness.

The first-quarter decline therefore strengthens copper’s structural bull case. Global demand is rising, while Chile’s mature mine base is struggling to deliver stable growth.

The Metalnomist Commentary

Chile’s copper problem is no longer only grade decline; it is now a combined issue of mine maturity, acid exposure, fuel costs and delayed expansion. The market should treat Chilean supply recovery as a slow process, not a quick response to record copper prices.

Vedanta Boosts Metal Production in Second Quarter Amid Efficiency and Capacity Gains

Vedanta

Indian mining giant Vedanta Resources reported a significant increase in metal production for the July-September quarter, citing improvements in operational efficiency and the addition of new production capacities. The growth was observed across several segments, including alumina, aluminum, zinc, lead, chrome, and copper, reflecting Vedanta's strategic efforts to enhance output.

Gains in Alumina and Aluminum Production

Vedanta's Lanjigarh refinery recorded a total alumina production of 499,000 metric tons in the second quarter, up from 464,000 metric tons in the same period last year. This increase was attributed to higher operational efficiency. On a half-year basis, production rose by 21% to 1.04 million tons from 895,000 tons during the same period in the previous year. Similarly, aluminum production increased to 460,000 metric tons in the July-September period, a rise from 447,000 metric tons a year ago.

Steady Growth in Zinc, Lead, and Chrome Output

The company's refined zinc and lead production also saw an 8% year-on-year increase, totaling 262,000 metric tons in the quarter. This growth was driven by improved metal grades and increased ore production across Vedanta's mining operations.

Vedanta's subsidiary, Ferro Alloys, reported a substantial rise in chrome ore production, which doubled to 38,000 metric tons from 18,000 metric tons during March-September last year. Ferro-chrome production also improved, reaching 26,000 metric tons, up from 22,000 metric tons, after the commissioning of a new furnace in August. The expansion was made possible after securing approval from India’s environment ministry, further bolstering Vedanta's output.

Copper Cathode Production Sees a 16% Increase

Vedanta's Silvassa smelter contributed to the positive results with a 16% rise in copper cathode production, reaching 41,000 metric tons for the July-September quarter. This marks a notable improvement from the same period last year, underscoring the company’s efforts to optimize its copper operations.

Overall, Vedanta’s strong performance across various metals showcases its focus on scaling production and leveraging efficiency improvements to meet market demand.

Kinterra Arizona copper project acquisition boosts US critical copper capacity

Kinterra Arizona Copper Project

Kinterra Arizona copper project acquisition marks a major expansion of the firm’s US copper footprint. The Kinterra Arizona copper project adds the Antler Copper Project to an existing portfolio in Michigan and Nevada. As a result, the Kinterra Arizona copper project positions the firm as a meaningful mid-tier copper player in North America.

Kinterra Arizona copper project strengthens multi-asset US platform

Kinterra fully acquired the Antler Copper Project from Australia’s New World Resources. With Antler added, Kinterra will control about 175,000t per year of copper capacity across White Pine, Pumpkin Hollow and Antler. The Antler asset itself is expected to produce 16,400t per year of copper when operational. It will also deliver 34,500t per year of zinc and 3,600t per year of lead as valuable by-products. These multi-metal streams improve project economics and diversify exposure beyond copper alone.

Earlier this year, US officials selected Antler for an expedited critical minerals permitting initiative. This fast-track status aims to compress the usual permitting timeline and support earlier production. All key permits are expected by the first quarter of 2026, with first production targeted for 2027. For downstream buyers, that schedule offers clearer visibility on future North American copper and zinc units.

Kinterra Arizona copper project ties into sulphide leach and cathode strategy

Kinterra is also launching a sulphide leach technology initiative across its US copper portfolio. The programme will assess and develop sulphide leach processing routes that could unlock domestic copper cathode production. Initial testing and pilot plans are expected in early 2026, aligning with the Antler project’s permitting milestones. If successful, this strategy could shift more material from concentrate exports toward higher-value refined cathode within the US.

This processing ambition supports US goals to deepen midstream copper capabilities, not just upstream mining. Integrating mining assets with emerging sulphide leach technologies may also improve recovery rates and lower unit costs over time. For policymakers and OEMs, such investments create additional optionality in a tightening global copper market.

The Metalnomist Commentary

Kinterra’s full control of Antler is a textbook example of private equity moving aggressively into critical copper supply. The combination of expedited permitting and sulphide leach innovation could turn this portfolio into a strategic domestic copper platform. Investors will now watch execution risk closely, especially around technology deployment and the 2027 production start.

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.
