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.

First Solar Module Guidance Holds as US Solar Manufacturing Scales

First Solar

First Solar module guidance remains unchanged for 2026 as the US thin-film solar manufacturer continues expanding domestic production while managing trade and policy uncertainty. The company expects to sell 17-18.2GW of modules this year, supporting projected sales of $4.9bn-5.2bn.

First Solar module guidance was reaffirmed after first-quarter module sales reached 3.8GW. Sales totalled slightly more than $1bn, up from $845.6mn a year earlier.

First Solar module guidance also reflects strong demand across the US and India. The company booked $1.7bn of new orders in the first quarter, showing that solar demand remains robust despite uncertainty around tariffs, investigations and energy policy.

The company expects second-quarter module sales of 3.4-4GW. Its contracted backlog stood at 47.9GW at the end of the quarter, worth about $14.4bn, with deliveries scheduled through 2030.

Trade Policy Shapes US Booking Strategy

First Solar said it will take a highly selective approach to US bookings while waiting for key trade policy outcomes. The company is watching the Section 232 investigation into polysilicon imports and the Section 337 investigation into solar cells and modules.

This matters because US solar manufacturing is increasingly shaped by trade rules, tax credits and reshoring policy. Producers must balance demand growth with the risk that tariff changes could alter pricing, margins and customer decisions.

First Solar produced 4.3GW of modules in the first quarter. Around 3GW came from US facilities, while 1.3GW came from international operations.

The company’s US plants ran at a 96% utilisation rate. By contrast, its Malaysia and Vietnam facilities remained underutilised because of tariff and policy uncertainty.

That split shows the advantage of domestic production in the current policy environment. US-made modules can benefit from stronger customer confidence, tax incentives and lower exposure to trade restrictions.

First Solar also expects Section 45X tax credits of $330mn-400mn in the second quarter, assuming the current US policy environment remains in place. These credits are a major support for domestic solar manufacturing economics.

Domestic Expansion Supports Reshoring Strategy

First Solar’s South Carolina finishing facility is expected to start production in the second half of this year. The facility will provide finishing capacity for Series 6 modules that begin production at overseas factories.

This expansion supports First Solar’s broader reshoring and localisation strategy. It allows the company to increase US-linked manufacturing content while maintaining flexibility across its global production network.

The company also completed the launch of its copper replacement technology at its Perrysburg, Ohio, facility at the end of the first quarter. This supports product development and manufacturing efficiency.

First Solar’s profit rose by 65% to $346.6mn in the first quarter. The increase shows that strong sales, high US utilisation and policy support are improving earnings.

The wider market signal is clear. Solar module demand remains strong, but the competitive landscape is being reshaped by trade investigations, domestic incentives and regional manufacturing strategies.

For materials and supply chains, this matters because solar production depends on stable access to glass, semiconductor materials, metals, chemicals, laminates and high-quality manufacturing equipment. Policy uncertainty can therefore influence not only module sales, but upstream material demand and factory utilisation.

First Solar’s maintained guidance shows confidence in demand. But the company’s selective booking strategy also shows that solar manufacturing is now as much about policy positioning as production capacity.

The Metalnomist Commentary

First Solar’s quarter shows that US solar manufacturing is being pulled forward by demand, tax credits and reshoring policy. The strategic risk is that trade uncertainty may keep global capacity underused even while domestic factories run near full utilisation.

Hudbay 2026 Production Guidance Holds as Copper Growth Shifts to Second Half

Hudbay Minerals

Hudbay 2026 production guidance remains unchanged after first-quarter output came in broadly in line with expectations. The Canadian mining company expects to produce 110,000-138,000t of copper this year across its Peruvian and Canadian operations.

Hudbay 2026 production guidance was maintained despite a 10% year-on-year fall in first-quarter copper output. The company produced 27,929t of copper in January-March, compared with 30,958t a year earlier.

Hudbay 2026 production guidance now depends on stronger second-half output from Peru and British Columbia. Mill improvements, grade sequencing and higher throughput are expected to support recovery through the rest of the year.

The company reported a strong financial result despite lower copper and zinc output. Profit attributable to shareholders rose by 90% to $190.4mn, while revenue reached a record $757.3mn.

Peru Throughput Offsets Pampacancha Depletion

Hudbay’s Peruvian copper production rose by 1% on the year to 20,573t in the first quarter. The increase came even though the Pampacancha mine was depleted at the end of 2025.

Record mill throughput at Constancia helped offset the loss of Pampacancha volumes. This shows the importance of processing performance when mine sequencing becomes less favourable.

Hudbay expects further throughput gains in the second half of 2026. The company plans to lift mill rates at Constancia after installing pebble crushers.

The Peruvian government also granted Hudbay a permit on 6 March to increase mill throughput to 31.3mn t/yr. This is 5% above the previous allowance of 29.9mn t/yr.

The permit is strategically important because it gives Hudbay more operating flexibility in Peru. Higher permitted throughput can help protect copper output when grades fluctuate or mine sequencing changes.

Hudbay said social unrest could continue in Peru after federal elections. However, the company does not expect production to be affected.

Canada Grades Weaken as Arizona Expansion Gains Importance

Hudbay’s Canadian copper output fell sharply because of lower ore grades. Manitoba copper production declined by 27% to 2,525t, while British Columbia output fell by 33% to 4,821t.

The company expects British Columbia production to improve in the second half as a mill improvement project supports operations. Manitoba zinc output should also strengthen later in the year on better grade sequencing and higher ore output at Lalor.

First-quarter zinc production fell by 27% to 4,565t, mainly because of lower grades at Manitoba operations. Molybdenum output in Peru slipped by 4% to 380t.

Hudbay said it is fairly well insulated from higher fuel costs linked to the US-Israel war on Iran. Its Manitoba operations require limited oil because underground equipment is electrically or battery driven.

This matters as fuel and logistics costs become more important for global miners. Operations with electrified underground fleets may have better protection against diesel price volatility.

Hudbay’s longer-term copper strategy is increasingly focused on the US. The company acquired Arizona Sonoran Copper Company in March through an all-share transaction worth about C$1.5bn.

It is also developing the Copper World project in Arizona with Mitsubishi’s US subsidiary. These assets give Hudbay future exposure to US copper demand tied to grids, electrification, manufacturing and supply-chain security.

The first-quarter result therefore shows a company balancing near-term grade pressure with longer-term copper growth optionality. Peru remains the key operating platform today, while Arizona could become more important in the next phase.

The Metalnomist Commentary

Hudbay’s unchanged guidance shows confidence in second-half operational recovery, but the grade pressure in Canada is a reminder that copper supply remains technically fragile. The Arizona strategy gives Hudbay a stronger long-term position as US copper supply becomes more strategic.

SRG NuCycle Acquisition Adds Low-Copper Shred Capacity in South Carolina

SRG

SRG NuCycle acquisition will expand Southeast Recycling Group’s scrap processing network with an automotive shredder capable of producing low-copper ferrous scrap. The deal strengthens SRG’s position in the southeastern US recycling market.

SRG NuCycle acquisition includes NuCycle’s Rock Hill, South Carolina, operations, its 4,000-horsepower Danieli shredder and auto parts yard Carolina Salvage. The transaction is expected to close later this month.

SRG NuCycle acquisition is strategically important because low-copper shred is increasingly valuable to steelmakers seeking cleaner ferrous feedstock. Better scrap quality supports electric arc furnace steelmaking, improves melt efficiency and reduces contamination risk in higher-grade steel products.

SRG will also gain downstream non-ferrous recovery capability through NuCycle’s existing system. This adds value beyond ferrous scrap by improving recovery of aluminium, copper, stainless and other non-ferrous fractions.

Low-Copper Shredder Strengthens Ferrous Scrap Quality

The acquired shredder is a 4,000-horsepower 80×108-inch Danieli unit. It includes a ballistic separator designed to produce a low-copper ferrous product.

This matters because copper contamination is one of the most important quality issues in ferrous scrap. Residual copper can limit the use of scrap in flat-rolled and higher-quality steel applications.

Low-copper shred gives processors a stronger product for steel mills that need cleaner scrap feedstock. It also helps bridge the quality gap between obsolete scrap and more controlled prime scrap streams.

SRG had previously planned to install a shredder at one of its existing sites. Instead, it chose to acquire an operating shredder platform, which can shorten the path to capacity and customer access.

The addition of Carolina Salvage also improves feedstock control. Auto parts yards can support shredder supply by bringing end-of-life vehicles and related material into the processing chain.

Consolidation Expands SRG’s Southeast Scrap Platform

SRG is also expanding through a separate merger with Morris Scrap Metal of Kings Mountain, North Carolina. Morris Scrap will join SRG as a new partner.

Once the NuCycle and Morris Scrap deals close, SRG will operate seven locations. The combined platform will have capacity of 300,000 gross tons per year of ferrous scrap and 150mn lb per year of non-ferrous scrap.

This scale gives SRG a stronger regional presence in the Carolinas and the broader southeastern US. It also improves collection density, logistics efficiency and customer coverage.

The deals continue SRG’s consolidation strategy after the company was formed last year from the merger of Carolina Metals Group and Spartan Recycling Group.

US scrap markets are becoming more competitive as steelmakers, aluminium producers and recyclers seek better feedstock quality and more reliable supply. Regional processors with shredding, sorting and non-ferrous recovery capacity are better positioned to serve that demand.

SRG’s expansion therefore reflects a wider industrial trend. Scrap recycling is moving from simple volume handling toward quality-controlled feedstock production for steel, aluminium and other metals supply chains.

The Metalnomist Commentary

SRG’s NuCycle deal shows that scrap processing value is shifting toward quality, not just tonnage. Low-copper shred and better non-ferrous recovery will matter more as US mills demand cleaner, more traceable recycled feedstock.

Nyrstar Australian Smelters Face Uncertain Future Without New Funding

Nyrstar

Nyrstar Australian smelters face an uncertain future as the company reviews possible closures or output curtailments at its Port Pirie lead smelter and Hobart zinc smelter. The review comes after interim government rescue funding expired without a second phase being agreed.

Nyrstar Australian smelters received A$135mn in interim support in August last year. The funding was designed to keep the 160,000 t/yr Port Pirie lead smelter in South Australia and the 280,000 t/yr Hobart zinc smelter in Tasmania operating while longer-term solutions were assessed.

Nyrstar Australian smelters are strategically important because they preserve domestic processing capability for base metals and potential critical minerals. But the facilities remain economically challenged by weak commodity pricing, high energy costs and the need for capital investment.

The company, owned by Trafigura, said it is now exploring all options for the two assets. No final decision has been made on closures or production cuts.

Port Pirie and Hobart Test Australia’s Industrial Policy

The Port Pirie and Hobart smelters sit at the centre of Australia’s debate over whether strategic processing capacity should be preserved through public support. Both assets are partway through two-year feasibility studies to diversify output into critical minerals such as bismuth and tellurium.

This diversification is important because traditional lead and zinc smelting margins have been under pressure. Adding critical minerals could improve the strategic value of the facilities and create new revenue streams.

Port Pirie has already started moving in that direction. The first shipment of antimony from a pilot plant was exported in February under the first-phase funding agreement.

Nyrstar said the Port Pirie pilot plant could produce 2,000 t/yr of antimony by the end of this year. That would be meaningful because antimony is increasingly viewed as a strategic metal for defence, flame retardants, batteries and industrial alloys.

Hobart has already faced production cuts during weaker zinc market conditions. That history shows how exposed the site remains to zinc prices, energy costs and operating margins.

Without a second funding phase, Nyrstar may cut capital expenditure and operating costs as part of the review. That could delay diversification plans and weaken Australia’s ability to preserve downstream metal processing capacity.

Critical Minerals Could Decide Smelter Value

The future of the two smelters may depend on whether they can become more than conventional lead and zinc assets. Processing critical minerals could give them a stronger role in Australia’s industrial strategy.

Australia’s Future Made in Australia policy aims to retain industrial capability and use renewable energy to support low-carbon exports, including metals. Smelters such as Port Pirie and Hobart fit that policy direction if they can become competitive and strategically relevant.

The challenge is cost. Existing smelters need reliable power, capital upgrades and market support to compete against lower-cost global processors.

Recent government support for aluminium and copper processors shows that Canberra is willing to intervene when strategic industrial assets face closure. But each case still needs a credible long-term pathway.

For Nyrstar, that pathway may involve antimony, bismuth, tellurium and other by-product metals. These materials can improve the value of complex smelting operations if they are recovered efficiently and sold into secure supply chains.

For Australia, the decision is broader than one company. Losing smelting capacity would weaken domestic processing depth at a time when governments are trying to reduce dependence on concentrated foreign refining systems.

The Metalnomist Commentary

Nyrstar’s Australian smelter review shows that critical minerals policy must extend beyond mining into processing assets that already exist. The key question is whether Australia can turn legacy smelters into strategic by-product platforms before high energy costs force permanent closures.

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.

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.

Teck Arizona Copper Spin-Out Preserves Optional Supply Upside

Kodiak Copper

Teck Arizona copper spin-out plans show how major miners are trying to retain long-term exposure to copper growth without committing near-term development capital. Teck Resources and junior explorer Kodiak Copper plan to place two lightly drilled Arizona copper projects into a new listed exploration company.

The Teck Arizona copper spin-out would combine Teck’s Copper Hill asset with Kodiak’s Mohave project under Kay Copper, a US-focused exploration vehicle. The new company would be positioned to drill and advance the assets, but any production would remain years away.

The Teck Arizona copper spin-out is modest compared with Teck’s larger strategic moves, including its planned merger with Anglo American. However, it fits a copper market increasingly focused on optional supply, future scarcity and the difficulty of bringing new mines into production.

The structure allows Teck to keep exposure to potential US copper upside while shifting exploration risk and funding needs to outside investors. For Kodiak, the transaction creates a clearer platform around Arizona copper exploration.

Kay Copper Gives Teck Exposure Without Near-Term Capital Pressure

Kay Copper would hold two early-stage Arizona copper projects that have not seen recent drilling. This means the assets are still far from any development decision, resource definition or mine construction timeline.

For Teck, that distance matters. The company can preserve future upside while focusing capital on larger, more advanced priorities. A spin-out also gives investors a dedicated vehicle for exploration risk that may not fit inside a larger producer’s near-term capital plan.

This is a practical response to the copper market. Demand from grids, electric vehicles, data centres and industrial electrification continues to strengthen the long-term case for copper.

At the same time, new copper supply remains difficult to build. Permitting delays, lower grades, higher capital intensity and community approval challenges have extended project timelines across the industry.

Arizona remains strategically relevant because the US wants more domestic copper supply. But early-stage projects still need drilling, studies, permitting, financing and infrastructure before they can become real tonnes.

The Kay Copper structure therefore does not solve near-term supply tightness. It creates an option on future US copper production in the 2030s.

Copper Market Rewards Optionality as New Supply Lags

The deal reflects a broader shift in copper strategy. Companies are increasingly trying to hold undeveloped assets because future supply is becoming more valuable.

Physical copper availability is already under closer scrutiny as demand rises from electrification and power infrastructure. The market is also becoming more policy-driven, especially in the US, where copper is increasingly linked to industrial security and domestic manufacturing.

In that environment, even early-stage assets can attract interest. They may not produce soon, but they offer exposure to a future market where permitted copper projects could carry a stronger strategic premium.

The transaction also shows how larger miners can use junior vehicles to advance non-core exploration assets. This allows capital markets to fund drilling while the major retains some upside.

For investors, the risk remains high. Copper Hill and Mohave are lightly drilled, and any production would not arrive until the 2030s at the earliest. Exploration success, permitting and project economics are still unproven.

For the copper sector, however, the message is clear. Companies do not want to lose optional copper positions in stable jurisdictions, even when those projects are not ready for development.

The Metalnomist Commentary

Teck’s Arizona spin-out is small in tonnage terms but meaningful in market psychology. In a copper market worried about future supply, even distant exploration assets can become strategic options.

Vale Thompson Nickel Belt Restructuring Secures New Capital for Canadian Nickel Supply

Vale Base Metals

Vale Thompson Nickel Belt restructuring marks a strategic move to keep one of Canada’s established nickel districts operating while reducing Vale’s direct exposure. Vale Base Metals has agreed to form a consortium for its Thompson nickel operations following a strategic review.

Vale Thompson Nickel Belt assets will receive up to $200mn in partner commitments to support long-term sustainability. Vale will retain an 18.9% interest in the consortium, while also securing a nickel concentrate offtake agreement.

Vale Thompson Nickel Belt restructuring matters because western buyers are paying closer attention to non-Indonesian nickel supply, origin transparency and long-term feedstock security. Thompson offers a Canadian source of nickel concentrate at a time when the market remains heavily influenced by Indonesian production growth.

The consortium is expected to close by the end of 2026, subject to regulatory approvals. Vale did not name the consortium partners.

Thompson Deal Preserves Exposure While Reducing Operating Risk

The new structure suggests Vale wants to keep Thompson in production without carrying the full capital and operating burden alone. The company is reducing direct exposure but preserving strategic access through its retained stake and concentrate offtake.

This matters because Thompson has faced operational pressure. Production at the mine fell by 66.7% on the year to 12,000t in the first quarter after a pipeline blockage was aggravated by poor weather.

The consortium model could help stabilise the asset if new partners bring capital, operational focus and a longer-term investment plan. For a mature nickel operation, sustaining capital and reliability upgrades can be as important as headline resource size.

The concentrate offtake agreement is equally important. It gives Vale continued access to material while allowing outside capital to support the mine’s future.

For western nickel supply chains, Thompson has strategic relevance beyond its near-term production volume. Non-Indonesian nickel units are becoming more valuable for buyers seeking diversified supply, lower geopolitical concentration and clearer provenance.

This is especially relevant for stainless steel, alloy, battery and defence-linked customers that want alternatives to Indonesia-dominated supply growth. Canadian nickel concentrate can help support that diversification if the operation remains stable.

Strong Copper and Nickel Prices Lift Vale Base Metals Earnings

The Thompson restructuring came as Vale Base Metals reported a sharp improvement in first-quarter earnings. Net revenue rose by 37% on the year to $2.38bn, while adjusted Ebitda more than doubled to $1.2bn from $554mn.

Nickel earnings recovered strongly. Adjusted nickel Ebitda climbed to $277mn from $41mn a year earlier, supported by higher realised prices, stronger sales, lower unit costs and better by-product credits.

Vale’s average realised nickel price rose by 6% to $17,015/t. Nickel sales volumes increased by 15% to 45,000t.

Cost improvements at Sudbury, Voisey’s Bay and Long Harbour also supported the nickel result. This shows that Vale’s Canadian nickel platform still has earnings leverage when operating performance improves and prices firm.

Copper delivered an even stronger contribution. Copper-adjusted Ebitda rose by 74% year on year to $949mn in the first quarter.

Vale’s realised copper price jumped by 48% to $13,143/t, while copper sales volumes rose by 18% to 72,000t. Stronger gold by-product revenues and improved performance at Sossego also supported the result.

The company increased copper sustaining capital expenditure by 54% to $83mn, with spending on the Bacaba copper project a key driver. Total copper capex, including growth spending, rose by 56% to $89mn.

At group level, Vale’s adjusted Ebitda rose by 23% to $3.83bn. The result shows how stronger copper and nickel prices can quickly improve earnings when production, sales and by-product credits align.

For Vale, the strategic message is clear. Copper provides growth and margin strength, while nickel requires selective restructuring, cost discipline and stronger asset-level sustainability.

The Metalnomist Commentary

Vale’s Thompson move shows that western nickel supply will increasingly depend on partnership models, not only mine ownership. The asset’s value lies in preserving Canadian concentrate supply at a time when buyers want alternatives to Indonesian nickel dominance.

Indonesia Nickel Pricing Sets Floor and Ceiling as HPAL Costs Rise

Huafei Nickel Cobalt

Indonesia nickel pricing is increasingly defining the global nickel market as ore quotas, benchmark pricing rules and sulphuric acid availability reshape supply economics. UK broker Sucden Financial said Indonesia is now setting both the floor and ceiling for nickel prices.

Indonesia nickel pricing has moved the market away from a simple oversupply story. The key question is no longer only how much nickel Indonesia can produce, but how tightly Jakarta chooses to manage supply.

Indonesia nickel pricing is also becoming more important because HPAL producers face rising costs for ore, sulphur and sulphuric acid. These inputs directly affect mixed hydroxide precipitate production, which feeds battery-grade nickel supply chains.

The London Metal Exchange nickel price settled at $19,500/t on Wednesday, while Sucden said Indonesia’s current policy stance is creating a firmer floor around $18,000/t. But upside may also be capped if higher prices encourage new quota approvals.

Indonesia Turns Ore Policy Into Market Control

Indonesia remains the central force in nickel because it controls the largest source of new supply. In recent years, Indonesian output growth, large exchange stocks and Chinese-linked processing capacity defined the market.

That structure is now changing. Sucden said Indonesia appears focused on supporting prices and discouraging weaker producers, rather than allowing unrestricted supply growth.

The country has reduced 2026 ore quotas by around 30% year on year. It has also revised its domestic benchmark ore pricing system, strengthening the link between ore valuation, contained metals and producer costs.

This policy approach gives Indonesia unusual pricing power. If supply is restricted, the market finds a firmer floor. If prices rise too far, Indonesia can relax quotas and allow more material through the system.

That means nickel’s upside is managed. Sucden warned that the market should become more cautious near $20,000/t, where additional supply approvals and producer hedging could begin to limit further gains.

This is why Indonesia now acts as both support and restraint. It can tighten ore availability to stabilise prices, but it can also prevent a strong rally from damaging downstream competitiveness.

The result is a more policy-driven nickel market. Traditional inventory and demand indicators still matter, but Jakarta’s quota and ore pricing decisions are now central to global price formation.

HPAL Costs Expose Battery Nickel Supply Risk

HPAL production is becoming the second major driver of nickel pricing. Unlike nickel pig iron and ferro-nickel, HPAL is highly dependent on sulphur and sulphuric acid.

This makes battery-grade nickel supply more vulnerable to chemical input availability. HPAL plants need stable acid supply to process limonite ore into MHP, and Indonesia’s inventory buffers are relatively tight.

Huayou’s decision to place half of its Huafei Nickel Cobalt MHP capacity into temporary care and maintenance from 1 May shows how quickly reagent costs can affect production. The company cited elevated sulphur costs and prolonged high operating rates.

The HPAL sector now faces a double squeeze. Ore prices are rising because of Indonesia’s revised pricing framework, while sulphur and sulphuric acid costs are increasing because of tighter chemical supply.

This changes the nickel cost curve. Producers with secure ore, sulphur access and integrated infrastructure can operate more defensively. Those relying on external feedstock or exposed to high reagent prices face greater margin pressure.

The shift also matters for battery supply chains. MHP is a key intermediate for nickel sulphate and other battery chemicals. If HPAL margins weaken, battery-grade nickel output can become less responsive than headline capacity numbers suggest.

Sucden said tighter nearby spreads and higher trading volumes may indicate increased hedging and another shift in market balance. That suggests producers and traders are adjusting to a market where costs and policy now matter more than simple surplus.

Nickel is still not structurally tight like copper. But it is no longer a market where oversupply alone explains price direction. Indonesia’s supply discipline and HPAL cost inflation are giving nickel a stronger base, even if the rally remains capped.

The Metalnomist Commentary

Indonesia has turned nickel into a managed market where policy controls supply and chemistry controls cost. The winners will be producers with secure ore, acid access and enough balance-sheet strength to survive Jakarta’s tighter discipline.

First Quantum Copper Output Falls But Cobre Panama Stockpile Lifts 2026 Guidance

First Quantum

First Quantum copper output declined in the first quarter as lower production from the company’s Zambian mines offset a sharp increase in nickel output. The Canadian miner produced 96,469t of copper in January-March, down 3.2% from a year earlier.

First Quantum copper output was weaker at both Kansanshi and Sentinel, the company’s two main operating copper assets in Zambia. Copper sales also fell by 11.7% to 90,049t because of shipment timing and inventory replenishment at Kansanshi after stronger sales in the previous quarter.

First Quantum copper output guidance for 2026 was raised despite the weaker first-quarter result. The company increased its full-year copper production outlook to 405,000-475,000t after Panama approved the processing and export of stockpiled ore at the closed Cobre Panama mine.

The approval changes the near-term production picture, but it does not reopen Cobre Panama. The mine remains closed after protests and a court ruling in 2023 found its operating contract unconstitutional.

Zambian Mines Weaken as Grades and Recoveries Pressure Output

Kansanshi produced 45,345t of copper in the first quarter, down 2.6% from a year earlier. The decline reflects the challenge of maintaining output from mature large-scale copper operations.

Sentinel produced 45,252t of copper, down 2.4% on the year. Lower feed grades and weaker recoveries reduced output at the mine.

These results show how copper supply can weaken even when operating assets remain active. Mine grades, recovery rates, mill performance and shipment timing all influence quarterly supply.

The weaker sales figure also matters. First Quantum sold 90,049t of copper in the quarter, below production, because of shipment timing and the need to rebuild Kansanshi inventories.

For copper markets, Zambia remains important because it is one of Africa’s key producing regions. Stable output from Kansanshi and Sentinel supports global supply at a time when buyers are increasingly focused on secure copper sources outside more politically sensitive routes.

First Quantum’s nickel production moved in the opposite direction. Output rose by 165.4% on the year to 12,340t, supported by higher grades and recoveries.

The nickel increase improves the company’s diversified metals profile. But copper remains the strategic core of First Quantum’s business and the main driver of market attention.

Cobre Panama Stockpile Approval Adds Near-Term Copper Supply

First Quantum raised its 2026 copper production guidance after Panama approved the removal, processing and export of stockpiled ore at Cobre Panama. The site will process around 38mn t of stockpiled ore containing about 70,000t of recoverable copper.

This approval gives First Quantum a short-term supply and cash-flow opportunity from material already mined before the shutdown. It does not involve new mining, drilling or blasting.

Cobre Panama was one of the largest copper mines in the Americas before its closure. It produced 331,000t of copper in its final year, equal to about 1.5% of global supply.

The mine’s shutdown removed a major source of copper supply and had a severe impact on First Quantum’s revenue base. The stockpile processing approval partly eases that impact, but only for material already on site.

The long-term future of Cobre Panama remains unresolved. Any return to mining would require a new political and legal settlement with Panama.

This distinction is important for copper markets. Stockpile processing can add near-term units, but it does not restore the full mine or solve the broader supply loss from the 2023 closure.

First Quantum kept its 2026 nickel production guidance unchanged at 30,000-40,000t. That suggests the main guidance change is tied directly to Cobre Panama’s approved stockpile treatment.

For investors and copper buyers, the company’s outlook now depends on two tracks. Zambia must stabilise operating performance, while Panama determines how much value can be recovered from Cobre Panama without reopening the mine.

The Metalnomist Commentary

First Quantum’s guidance increase is a stockpile story, not a full Cobre Panama recovery story. The approval adds useful copper units, but the real strategic question remains whether Panama and First Quantum can ever rebuild a legal framework for long-term mining.

Copper Aluminium Pricing Divergence Deepens as Middle East Shock Turns Metal-Specific

Sucden Financial

Copper aluminium pricing divergence is becoming clearer as base metal markets absorb the first shock of the Middle East conflict. Copper is shifting back toward physical flows, inventories and policy risk, while aluminium remains supported by direct disruption to Middle East supply chains.

Copper aluminium pricing divergence reflects a broader change in market behaviour. Traders are moving away from headline-led volatility and focusing more on spreads, premiums, inventories and real supply constraints.

Copper aluminium pricing divergence also shows that the base metals complex is no longer trading as one geopolitical basket. Each metal is now being priced according to its own exposure to the war, its physical balance and its ability to replace disrupted supply.

UK broker Sucden Financial said the conflict initially drove broad volatility across commodities. But that phase is fading, leaving copper and aluminium on different pricing paths.

Copper Moves From Macro Risk to Physical and Policy Pricing

Copper began the year as a macro-driven metal. Prices moved with broader risk sentiment, oil, gold and cross-asset positioning.

That relationship is now weakening. Copper is increasingly being priced through its own market signals, including Shanghai inventory drawdowns, US flow incentives, mined supply quality and sulphuric acid-related supply-chain disruption.

This shift matters because copper is no longer responding only to global growth fears or geopolitical headlines. It is being priced through physical availability and policy exposure.

The Comex premium has periodically reopened the arbitrage for copper units to move into the US. This has made the interaction between LME, Comex, inventories and US policy more important to price discovery.

Sucden said the next phase of copper pricing could be shaped by material-security concerns. These include tariff threats, incentives to hold more metal in the US and the strategic value of copper in energy infrastructure.

This is a macro-to-micro rotation. Copper is moving away from broad geopolitical trading and toward a market driven by premiums, spreads, stock locations and supply-chain constraints.

Sulphuric acid remains a key hidden risk. Copper supply from leaching operations, particularly in regions such as the Democratic Republic of Congo and Chile, can be affected if acid availability tightens or costs rise.

The market still remains exposed to recession fears. A deeper economic slowdown caused by the conflict could weigh on copper demand and financial positioning.

However, copper’s resilience suggests that traders are giving greater weight to structural tightness. Supply challenges, low-quality mined material and long-term demand from grids, electrification and industrial policy continue to support the metal.

Sucden argued that copper’s long-term direction remains higher and that price dips should be bought. The structural case has not changed, while eventual dollar weakness after a conflict resolution could provide further support.

Aluminium Holds a Firmer Physical Floor After Supply Shock

Aluminium has already repriced much of the Middle East disruption. The metal briefly moved toward the upper end of its recent range as the conflict escalated, but repeated failures above $3,650/t suggest the market needs further supply deterioration to justify another major move higher.

This does not mean aluminium is weak. It means the initial panic premium has already been absorbed.

Aluminium’s support is more physical than copper’s. The disruption affects smelting, feedstock flows and export availability from the Middle East, making the supply shock more direct than headline numbers may suggest.

Sucden said aluminium remains the base metal with the clearest exposure to the Middle East war. Ex-China supply is tighter, London Metal Exchange inventories are falling and nearby spreads have moved into backwardation.

Chinese inventories have risen, but that does not fully offset the tightness outside China. Regional availability matters more when logistics, origin and delivery routes are disrupted.

Aluminium smelters also cannot restart quickly. Once production is curtailed, bringing capacity back requires time, stable power and commercial confidence.

Elevated energy prices add another layer of cost support. Even if the war de-escalates, smelters and downstream producers may still face a higher operating cost base.

Sucden said de-escalation could initially push aluminium prices toward $3,400/t. But any decline may prove short-lived if physical tightness remains.

This gives aluminium limited immediate upside but also limited downside. The market has already priced much of the shock, yet replacement supply is not easy to find.

The broader implication is that aluminium is trading a tighter physical balance, not only a war premium. That makes its price floor firmer than a market driven purely by sentiment.

For industrial buyers, the copper-aluminium split is important. Copper procurement risk is increasingly tied to policy, US flows and strategic inventory. Aluminium risk is tied more directly to missing tonnes, energy costs and disrupted regional supply.

The Metalnomist Commentary

The Middle East conflict is exposing the real structure of each base metal market. Copper is becoming a policy-and-premium metal, while aluminium is being supported by a more immediate physical supply shock.

Anglo American Copper Output Rises as Chile Offsets Quellaveco Grade Decline

Anglo American, Copper

Anglo American copper output rose slightly in the first quarter as stronger Chilean mine performance offset lower grades at Quellaveco in Peru. The global mining group produced 170,400t of copper during the quarter, up 1% from a year earlier.

Anglo American copper output was supported by higher throughput at Los Bronces and Collahuasi, along with improved recoveries at Collahuasi. Chilean copper production increased by 9% to 97,000t, while Peruvian output fell by 8% to 73,400t.

Anglo American copper output remains on track with unchanged 2026 guidance of 700,000-760,000t. The company had already lowered that target in February because of expected lower grades at Collahuasi.

The result confirms that copper remains Anglo’s strategic centre as the group continues reshaping its portfolio. Nickel is moving toward disposal, manganese is recovering from weather disruption, and copper is becoming the company’s clear lead business.

Los Bronces and Collahuasi Support Chilean Copper Performance

Los Bronces output rose by 12% to 48,500t after the restart of its second plant. The restart improved throughput and gave Anglo a stronger base in Chile during the quarter.

Collahuasi also delivered a stronger result. Anglo’s attributable share of production rose by 10% to 38,800t, supported by higher throughput and improved recoveries.

These gains helped offset weaker output from Quellaveco. The Peruvian mine faced expected lower grades, reducing copper production despite its importance as one of Anglo’s major growth assets.

The first-quarter result shows how copper production increasingly depends on ore grade, plant availability and recovery performance. Higher throughput can support output, but grade decline remains a major constraint across the industry.

Anglo’s growth is still weighted toward the second half of the year. Market attention will focus on Collahuasi’s return to higher-grade ore, the ramp-up of desalination capacity and the continued benefit from Los Bronces’ second plant restart.

The proposed merger with Teck Resources also remains important. Anglo said the deal is still on track for completion between September 2026 and March 2027. South Korean approval has been secured, leaving Chinese anti-monopoly clearance as the final major regulatory hurdle.

If completed, the merger would deepen Anglo’s copper exposure and reinforce the industry trend toward scale in high-quality copper assets.

Nickel Falls as Manganese Rebounds From Weather-Hit Base

Anglo’s nickel production fell by 7% year on year to 9,100t because of maintenance at Barro Alto and Codemin in Brazil. Barro Alto output declined by 7% to 7,500t, while Codemin fell by 6% to 1,600t.

The company expects nickel production to improve gradually from the second quarter. However, nickel is no longer central to Anglo’s long-term portfolio strategy.

Anglo is still working through the European Commission’s anti-monopoly review of the agreed sale of its nickel assets to MMG Singapore Resources. The deal is worth up to $500mn.

Manganese ore output rose sharply from a weak base. Anglo’s 40% attributable production jumped by 118% to just over 759,000t after operations recovered from the disruption caused by tropical cyclone Megan in early 2025.

Sales volumes rose even more strongly, increasing by 217% to 946,000t. However, weather still affected the business, with second-quarter output down 16% from the fourth quarter of 2025 because of adverse weather and cyclone Narelle.

The portfolio direction is now clearer. Anglo is prioritising copper and iron ore while continuing sale processes for steelmaking coal and De Beers. Nickel is becoming a disposal asset, and manganese remains a recovery story after weather-related disruption.

For copper markets, Anglo’s modest first-quarter increase is less important than its second-half execution. The company needs stronger grades, stable plant performance and project discipline to support its full-year copper target.

The Metalnomist Commentary

Anglo American’s first quarter shows that copper growth is increasingly a quality-of-ore and processing-efficiency story. The strategic focus now shifts to whether Collahuasi, Los Bronces and the Teck merger can turn Anglo into a more copper-led mining company.

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.

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.

Korea Zinc Tennessee Smelter Gains FAST-41 Support for Critical Minerals Refining

Korea Zinc

Korea Zinc Tennessee smelter plans have gained federal permitting support after the US Permitting Council added Project Crucible to FAST-41 coverage. The designation is intended to speed permitting for the proposed smelting and refining facility in Clarksville, Tennessee.

The Korea Zinc Tennessee smelter would produce 12 non-ferrous metals, including zinc, copper, lead, antimony, gallium and germanium. It would also produce semiconductor-grade sulfuric acid, making the project strategically relevant to metals, chemicals and semiconductor supply chains.

The Korea Zinc Tennessee smelter is significant because it would be the first large-scale domestic zinc refinery built in the US since the 1970s. It also reflects Washington’s effort to rebuild domestic refining capacity for critical minerals and reduce dependence on overseas processing.

Project Crucible is planned as a $7.4bn investment. Korea Zinc announced the project in December in a joint venture with the US commerce and defense departments after acquiring the adjacent East Tennessee and Mid Tennessee mining complexes and the Clarksville smelter from Trafigura-owned Nyrstar.

Project Crucible Targets a Multi-Metal Refining Gap

Project Crucible is designed to process 1.1mn t/yr of raw materials and produce 540,000 t/yr of finished products. Korea Zinc expects to source feedstock mainly from the US and other North American sources.

This feedstock strategy matters because the US has mine supply and scrap flows, but lacks enough large-scale refining and separation capacity for several strategic materials. Project Crucible could help close that midstream gap.

The product mix is especially important. Zinc, copper and lead provide scale, while antimony, gallium and germanium add critical minerals value.

Gallium and germanium are strategically sensitive because they are used in semiconductors, fibre optics, infrared systems, defence electronics and advanced manufacturing. Antimony is also important for flame retardants, ammunition, lead alloys and military applications.

The facility’s semiconductor-grade sulfuric acid output adds another layer of industrial importance. High-purity sulfuric acid is a key chemical input for semiconductor manufacturing and advanced electronics.

Korea Zinc plans to base the facility on its Onsan smelter in South Korea. That gives the project an established technical reference point and strengthens its credibility as a complex multi-metal refining platform.

FAST-41 Status Supports US Industrial Supply Security

FAST-41 coverage gives Project Crucible a more coordinated federal permitting path. The Permitting Council also signed a memorandum of understanding with Tennessee to align federal and state permitting efforts.

The US Department of Defense will primarily oversee permitting for the project. That role underlines the national security importance of domestic critical minerals refining.

Korea Zinc expects construction to begin in 2027. Phased operations are scheduled to start in 2029 with zinc, lead and copper production.

Finished products are expected to move to US customers by rail. This gives the project a domestic logistics route and supports the broader goal of building mine-to-market North American supply chains.

The project fits a wider US strategy. Washington is trying to accelerate permitting, use defence-linked financing and support domestic refining capacity for materials used in semiconductors, defence, energy infrastructure and manufacturing.

For Korea Zinc, the project offers a major entry into US critical minerals processing. For the US, it provides a rare chance to add large-scale refining capacity across both base metals and strategic minor metals.

The Metalnomist Commentary

Project Crucible shows that the US critical minerals challenge is increasingly about refining, not only mining. If Korea Zinc can execute the Tennessee smelter on schedule, it could become one of the most important non-Chinese multi-metal refining assets in North America.
