Mt Carbine Tungsten Mine Expansion Targets Higher Australian Supply

EQ Resources

Mt Carbine tungsten mine operator EQ Resources has approved a A$39mn expansion that will double ore crushing capacity at its Queensland operation. The investment comes as tungsten prices remain elevated following Chinese export controls and stronger global defence demand.

Mt Carbine tungsten mine crushing capacity will increase from 1mn t/yr to 2mn t/yr. EQR expects the project to come online in the January-March quarter of 2027.

Mt Carbine tungsten mine expansion will address the main processing bottleneck at the operation. Additional crushing capacity will allow EQR to process more low-grade stockpiled ore and increase tungsten recovery from material already available at the site.

The company expects the project to add 500 metric tonne units per year of tungsten trioxide output. One mtu represents 10kg of 100% tungsten trioxide content.

Crushing Expansion Unlocks Existing Tungsten Feedstock

Crushing capacity has constrained Mt Carbine’s ability to increase processing volumes. Doubling capacity gives EQR a relatively direct route to higher output without relying entirely on new mine development.

The project will particularly improve access to low-grade stockpiles. This is important because higher tungsten prices can make previously marginal material increasingly economic to process.

EQR plans to fund the expansion through existing cash reserves and expected cash flows from tungsten trioxide sales. The company therefore avoids depending entirely on new external financing for the project.

The economics have improved dramatically as tungsten prices have risen. European ammonium paratungstate prices recently reached around $3,000/mtu, up 590% from a year earlier.

Chinese export controls introduced in February 2025 have been a major driver. Tight Chinese domestic supply and rising defence demand have further strengthened the market.

Tungsten is strategically important because of its hardness, heat resistance and high density. It is used in cutting tools, aerospace components, electronics and defence applications.

Offtake Agreements Secure Routes for Additional Supply

EQR does not expect to rely on a conventional spot market for additional tungsten trioxide output. The company said incremental production will instead move through existing offtake agreements.

Traxys has an agreement covering 3,500 t/yr, while US tungsten manufacturer Elmet Technologies has secured an undisclosed quantity.

EQR has also signed agreements with five undisclosed tungsten manufacturers across Asia, North America and Europe. These contracts cover a combined 9,400t of 50% grade tungsten concentrate over two years.

This diversified offtake structure is strategically significant. Tungsten markets are relatively small and specialised, making long-term customer relationships more important than highly liquid spot trading.

The agreements also connect Australian tungsten production directly with processing and manufacturing customers across several regions. That strengthens Mt Carbine’s role as a non-China tungsten source.

With Chinese export controls increasing procurement risk, western manufacturers are placing greater value on diversified and contractually secured supply. Mt Carbine is positioned to benefit from that shift if EQR completes its expansion on schedule.

The Metalnomist Commentary

Mt Carbine shows how high tungsten prices are making existing stockpiles and brownfield expansions more valuable. EQR’s real strategic advantage is the combination of available feedstock, secured offtake and growing demand for non-China tungsten.

Australia Mineral Exploration Spending Rises as Iron Ore and Gold Attract Capital

Iron ore

Australia mineral exploration spending increased strongly in the first quarter, supported by higher investment in iron ore and gold despite weaker spending on copper, nickel, cobalt and coal.

Australia mineral exploration spending rose by 16.3% year on year to A$949.3mn in January-March, according to Australian Bureau of Statistics data. Gold and iron ore remained the two largest categories of exploration expenditure.

Australia mineral exploration spending patterns show a widening divide between commodities. Producers are continuing to invest in iron ore reserve replacement, while weak nickel and cobalt prices are discouraging new exploration.

Iron ore exploration expenditure increased by 4.7% year on year to A$186mn. Gold exploration spending climbed much faster, rising by 53.4% to A$450.9mn.

Iron Ore Investment Stays Strong as Producers Replace Reserves

Iron ore remains one of Australia’s most important mining commodities, and continued exploration spending reflects the need to replace depleting reserves at established operations.

Australia’s Office of the Chief Economist expects domestic iron ore exploration to remain strong as major producers sustain long-term mine life and feed quality.

This is strategically important because Australia remains a major supplier to Asian steelmakers. Maintaining reserve depth is essential for preserving export volumes, mine productivity and Australia’s position in the seaborne iron ore market.

Gold recorded the largest increase in exploration spending. The 53.4% year-on-year rise to A$450.9mn suggests stronger investor appetite for projects offering exposure to high gold prices and more favourable project economics.

Silver, lead and zinc exploration also strengthened, with spending rising by 29.9%. These metals benefit from a combination of precious metal exposure and demand from industrial, infrastructure and energy applications.

Nickel, Cobalt and Coal Lose Exploration Momentum

Nickel and cobalt exploration spending fell by 42.7% year on year, reflecting persistent weakness in global nickel markets and deteriorating economics for Australian producers.

The Office of the Chief Economist expects nickel prices to remain under pressure through 2027 because of continuing global surpluses. Weak pricing has already reduced Australian mine output and discouraged investment in new resources.

Copper exploration spending also declined by 13.1%. This contrasts with copper’s stronger long-term demand outlook and shows that high development costs, permitting risk and competition for capital can still limit exploration despite positive structural demand.

Coal exploration expenditure fell by 22.7% to A$43.2mn. Policy and cost pressures are reinforcing the decline.

New South Wales stopped issuing permits for greenfield thermal coal developments in March 2026, while high royalty rates in Queensland may also be discouraging investment in coking coal exploration.

The result is a more selective Australian exploration market. Capital is flowing toward commodities with stronger pricing, established infrastructure and clearer long-term economics, while weaker or policy-constrained sectors are losing investment.

The Metalnomist Commentary

Australia’s exploration data show that capital is becoming increasingly selective even within strategic minerals. Strong iron ore and gold spending contrasts sharply with nickel and cobalt, where weak economics are overriding long-term critical minerals ambitions.

International Graphite Wogen Offtake Builds Asia-Pacific Supply Route

Graphite

International Graphite Wogen offtake plans could create a new Australia-to-Asia graphite supply route as International Graphite prepares to commission its Collie processing facility in Western Australia. The non-binding agreement combines concentrate supply with downstream sales of micronised spherical graphite.

International Graphite Wogen offtake terms allow Wogen to supply up to 10,000 t/yr of graphite flake concentrate to Collie. In return, International Graphite would supply at least 3,000 t/yr of micronised spherical graphite to Wogen’s Pacific arm for exclusive marketing across Asia-Pacific.

International Graphite Wogen offtake is strategically relevant because Japan and South Korea are major battery and advanced materials markets seeking more diversified graphite sources outside China. Commercial terms will be negotiated on a spot basis, while Wogen may provide credit lines to support transactions.

The companies aim to convert the arrangement into a binding agreement before the 4,000 t/yr Collie facility begins commercial production in mid-2027.

Collie Creates Midstream Graphite Capacity Outside China

The Collie plant gives International Graphite a route into higher-value graphite processing rather than relying only on upstream mining. The facility will produce micronised spherical graphite from imported flake concentrate during its initial operating phase.

This matters because graphite value chains depend heavily on processing. Natural graphite must undergo sizing, shaping, purification and coating before it can qualify as active anode material for lithium-ion batteries.

The material produced at Collie will still require additional processing before use in battery anodes. That means the project sits in the midstream rather than representing a fully integrated battery-anode supply chain.

However, the Wogen agreement creates a commercial bridge into Japan and South Korea. Both markets have established battery, automotive and electronics industries that require secure sources of processed graphite.

Wogen’s ability to supply up to 10,000 t/yr of concentrate also gives International Graphite feedstock flexibility while its own mining plans remain on hold.

The Collie commissioning schedule has moved to mid-2027 from an earlier January 2027 target. Production is expected to ramp over the following 18 months.

Springdale Delay Highlights Processing-First Strategy

International Graphite ultimately plans to source flake graphite from its Springdale project in Western Australia. But the company has paused exploration and drilling while concentrating capital and management resources on Collie and its Italian midstream joint venture with Alkeemia.

This sequencing reflects a pragmatic strategy. Building processing capability first can establish customers, product qualification and market access before the company commits larger capital to mine development.

Springdale received A$4.7mn in Australian federal government support in 2023. The resource could eventually provide domestic feedstock to Collie and create a more vertically integrated Australian graphite chain.

For now, the project will rely on external concentrate. That reduces near-term upstream development risk but increases dependence on third-party feedstock availability and pricing.

The Wogen arrangement helps manage that exposure while providing an outlet for processed material. If converted into a binding contract, it would cover a substantial share of Collie’s planned production capacity.

The broader opportunity is ex-China graphite diversification. China remains dominant in spherical graphite and battery-anode processing, making new midstream capacity in Australia strategically important even before full anode qualification is achieved.

The Metalnomist Commentary

International Graphite is prioritising the hardest commercial step first: building processing capacity and customer routes before expanding its mine. If Collie secures reliable feedstock and qualifies into Asian markets, Springdale can later become the upstream anchor of a more integrated ex-China graphite chain.

US Rare Earths Spending Spree Builds Mine-to-Magnet Power Outside China

Energy Fuels

US rare earths spending spree has rapidly reshaped the non-China industry as American companies acquire mining, refining, metal-making and permanent magnet assets around the world. Large government loans, grants and offtake guarantees have given US-backed groups the financial capacity to consolidate strategic assets across the full value chain.

US rare earths spending spree accelerated with Energy Fuels’ planned $1.9bn acquisition of German permanent magnet maker Vacuumschmelze. The deal follows its $299mn purchase of Australian Strategic Materials, which owns one of the few commercial rare earth metal and alloy plants outside China.

US rare earths spending spree is therefore moving beyond domestic production. Washington-backed capital is allowing US companies to build control or commercial influence over rare earth assets in Europe, South America, Australia, Greenland and Asia.

The result is an emerging US-centred supply network covering mines, separated oxides, metals, alloys and finished NdFeB magnets. That structure could become more important than ownership of any single mineral deposit.

Government Capital Accelerates Global Rare Earth Consolidation

US industrial policy has shifted decisively toward financing complete rare earth supply chains rather than isolated mining projects.

Energy Fuels received a conditional $725mn loan commitment for rare earth processing before announcing the VAC acquisition. Buying the German magnet producer gives Energy Fuels downstream manufacturing capability to complement its growing separation and metal-making assets.

The company had already acquired Australian Strategic Materials in January. ASM’s Korean Metals Plant adds commercial rare earth metal and alloy production, a critical midstream step between separated oxides and permanent magnets.

Other US companies are following the same integration strategy.

USA Rare Earth acquired Brazilian producer Serra Verde for $2.8bn in April. Serra Verde is targeting 6,400 t/yr of rare earth oxide production by 2027, giving USAR direct exposure to one of the more advanced rare earth mining operations outside China.

USAR had previously bought UK-based Less Common Metals for $125mn, adding metal and alloy production capability. That combination links upstream Brazilian resources with downstream metallisation expertise.

Critical Minerals also agreed to acquire European Lithium for $835mn to consolidate ownership around Greenland’s Tanbreez rare earth project.

The pattern is consistent. US-backed companies are using access to capital to purchase scarce assets that would otherwise require years to build and qualify independently.

Government support has made this possible. MP Materials received a multi-billion-dollar package including a price floor, guaranteed offtake and direct government investment. Vulcan Elements and ReElement Technologies received conditional financing support, while USA Rare Earth secured a major federal funding package for its mine-to-magnet development.

Phoenix Tailings also received substantial government-backed financing for rare earth refining.

This capital does more than reduce project risk. It gives US companies the balance-sheet strength to bid for strategic assets elsewhere.

Europe Risks Losing Strategic Control of Its Rare Earth Assets

The US acquisition wave exposes a major weakness in European and other western critical minerals strategies: policy ambition has not always been matched by comparable financing.

Europe still retains important rare earth capabilities. Solvay operates rare earth processing capacity in France, while Neo Performance Materials produces magnets in Estonia.

But ownership is increasingly shifting toward North American groups. VAC will become US-owned if the Energy Fuels transaction closes, while Neo Performance Materials is already controlled from North America.

The same dynamic is emerging in project development. Companies seeking large-scale financing increasingly look to US government programmes rather than domestic European sources.

UK-based Pensana abandoned plans for a UK rare earth refinery and shifted its downstream strategy toward the US, illustrating how capital availability can redirect industrial investment.

This creates an important policy distinction. A rare earth asset can remain physically located in Europe, Brazil, Greenland or Australia while its financing, offtake and strategic direction become increasingly tied to US interests.

That makes Washington’s influence broader than domestic production statistics suggest.

The US does not need every mine or refinery to sit inside its borders. If US-backed companies own assets, control offtake, provide financing or anchor downstream demand, they can still direct material into allied supply chains.

This approach may prove faster than attempting to develop every stage domestically from scratch.

China still dominates global rare earth processing and permanent magnet manufacturing. But outside China, the competitive landscape is increasingly being shaped by access to government-backed capital and the ability to integrate fragmented assets.

The next phase of the rare earth competition will therefore be about ownership and industrial coordination as much as geology. Companies that connect mines, separation, metallisation, alloys and finished magnets will hold the strongest strategic position.

The Metalnomist Commentary

The US is building rare earth influence by financing companies that can buy and integrate scarce ex-China assets. Europe and other allies may retain the mines and factories geographically, but without comparable capital they risk losing strategic control of the value chain.

Nickel Industries HPAL Expansion Targets Indonesian MHP Growth Through Acquisitions

Tsingshan

Nickel Industries HPAL expansion will move forward through acquisitions rather than new project development as Indonesia tightens control over additional high pressure acid leach capacity. The Australian producer will acquire stakes in two MHP projects next to its existing Excelsior Nickel Cobalt operation in Central Sulawesi.

Nickel Industries HPAL expansion is strategically important because Indonesia has stopped issuing licences for new HPAL developments since late 2025, according to the company. That makes existing permitted projects increasingly valuable to producers seeking battery-grade nickel growth.

Nickel Industries HPAL expansion covers the planned Teluk Metal Industry and Chengsheng New Energy projects. Together, the stakes would give NI attributable MHP capacity of almost 17,000 t/yr.

Both projects are located in the Indonesia Morowali Industrial Park and will use ore from NI’s Sampala mine. Their output will feed the electric vehicle battery supply chain.

TMI and CNE Add MHP Capacity Around Existing ENC Platform

NI will pay $169mn for a 17.5% stake in the Teluk Metal Industry HPAL project. TMI has planned nameplate MHP capacity of 38,640 t/yr, giving NI 6,775 t/yr of attributable output.

The transaction also carries construction protection from Tsingshan. The Chinese nickel and stainless steel producer has guaranteed that NI’s investment will be capped at $169mn and that TMI will reach nameplate production by September 2027.

This lowers construction risk for NI and reinforces its relationship with Tsingshan, which already owns an indirect 44% stake in the ENC project.

TMI’s remaining ownership includes Singapore-based Sumber International Investment and a South Korean-Japanese consortium involving LS MnM, Hanwa and another strategic investor. The structure shows how Asian industrial groups are positioning themselves around Indonesian battery nickel supply.

NI is also pursuing a 36% stake in the Chengsheng New Energy HPAL project together with a local partner. The acquisition will be funded by transferring 30% of their combined ownership in the Sampala nickel mine.

CNE has MHP capacity of 28,357 t/yr, with 10,208 t/yr attributable to NI. Commissioning is expected by mid-2027.

The CNE transaction still requires shareholder approval because an NI director is associated with the selling investment firm. That adds a governance step before completion.

Indonesia Licensing Limits Increase Value of Existing HPAL Assets

Indonesia’s decision to stop issuing new HPAL licences changes the economics of nickel expansion. Producers can no longer rely on greenfield development to add battery-grade processing capacity.

This gives existing permitted projects a scarcity premium. Companies seeking growth must acquire stakes, partner with current licence holders or expand existing operations.

For NI, TMI and CNE extend the company’s battery nickel platform around ENC. The 46%-owned ENC project is preparing to produce nickel cathode and nickel sulphate, giving NI exposure further downstream than MHP alone.

The strategy also integrates mining and processing. Ore from the Sampala project will supply both TMI and CNE, linking captive feedstock with HPAL conversion and battery-material output.

That integration matters because Indonesia’s nickel industry is increasingly constrained by ore availability, regulatory approvals and government efforts to manage oversupply.

The policy shift could support nickel prices by slowing future HPAL growth. But it also raises the value of projects already holding development rights.

For NI, acquisitions therefore become more than a growth option. They are now the main route to expanding Indonesian MHP production under a tighter licensing regime.

The Metalnomist Commentary

Indonesia’s HPAL licensing freeze is turning permitted projects into strategic assets. Nickel Industries is responding by buying access to existing capacity, showing how policy can shift competition from project development to asset acquisition.

Energy Fuels VAC Acquisition Builds Mine-to-Magnet Rare Earth Platform

Vacuumschmelze

Energy Fuels VAC acquisition will create one of the most vertically integrated rare earth supply chains outside China by combining upstream mining and separation with commercial magnet manufacturing. The US rare earths and uranium producer will acquire Germany-based Vacuumschmelze for $1.9bn in cash and stock.

Energy Fuels VAC acquisition gives the company immediate downstream exposure to permanent magnets, including sintered neodymium-iron-boron products, as well as cobalt-iron and nickel-iron soft magnetic materials. VAC serves customers across electrification and industrial markets.

Energy Fuels VAC acquisition also addresses one of the biggest weaknesses in western rare earth strategy. Mining and oxide separation alone do not create a complete magnet supply chain. Rare earth metals, alloys, powders and finished magnets must all be produced and qualified.

The transaction will leave VAC as a wholly owned Energy Fuels subsidiary while maintaining its German headquarters. The structure gives Energy Fuels manufacturing assets across North America, Europe and Asia.

VAC Adds Commercial Magnet Capacity to Upstream Rare Earth Assets

VAC brings established permanent magnet manufacturing capability into Energy Fuels’ portfolio. Its Sumter, South Carolina, facility currently has 2,000 t/yr of permanent magnet capacity.

That site has significant expansion potential. Capacity could eventually rise to as much as 12,000 t/yr, creating a large US manufacturing base for NdFeB magnets.

The strategic value is substantial because permanent magnets sit at the end of a complex rare earth value chain. Neodymium and praseodymium provide the main magnetic properties, while dysprosium and terbium can improve performance at elevated temperatures.

Energy Fuels has already started developing those upstream materials. The company produced pilot-scale high-purity terbium oxide in March 2026 and produced its first dysprosium oxide at the White Mesa Mill in Utah in August 2025.

VAC therefore gives Energy Fuels a downstream destination for materials it is increasingly able to separate and refine itself.

The company also plans to acquire Australian Strategic Minerals, which would add commercial-scale rare earth metal and alloy capacity in South Korea and a planned metals plant in the US.

If both transactions are completed and expanded successfully, Energy Fuels would control a chain extending from mineral resources through oxide separation, metal-making, alloying and finished magnets.

US Government Finance Supports Rare Earth Industrial Integration

Government support is becoming central to Energy Fuels expansion. The company has secured a conditional commitment from the US Office of Strategic Capital for a 20-year loan of up to $725mn.

The financing is intended to accelerate expansion of the White Mesa Mill and construction of a US rare earth metals facility. This helps close the gap between separated oxides and magnet-ready metal and alloy products.

VAC has also received US government support. The company secured a $41mn grant from the US Department of State to develop a US metal-making facility.

These investments show that US rare earth policy is moving toward full-chain industrial capability rather than isolated upstream projects. The focus is increasingly on converting mineral resources into qualified finished components.

For automotive, defence, robotics and industrial customers, this matters because secure magnet supply depends on multiple linked stages. Any missing stage can recreate dependence on external processing.

Energy Fuels is therefore pursuing an unusually broad strategy. The company is not only adding production capacity; it is trying to internalise several of the most difficult steps in the rare earth value chain.

The challenge will be integration. Mining, separation, metallurgy and magnet manufacturing require different technical capabilities, customers and qualification systems. The value of the transaction will depend on whether Energy Fuels can connect those operations efficiently at commercial scale.

The Metalnomist Commentary

Energy Fuels is moving beyond rare earth mining into one of the most complete western mine-to-magnet strategies yet attempted. If the VAC and metals acquisitions are integrated successfully, the company could become a major non-China supplier of both heavy rare earth materials and finished NdFeB magnets.

Mt Marion Lithium Expansion Advances as MinRes and Ganfeng Lift Spodumene Supply

Mineral Resources

Mt Marion lithium expansion is moving ahead after Mineral Resources and Jiangxi Ganfeng Lithium reached a final investment decision on a A$490mn upgrade at the Western Australian mine. The project will raise 6% spodumene concentrate output from 500,000 t/yr to 600,000 t/yr.

Mt Marion lithium expansion reflects renewed confidence in spodumene markets after a period of stronger pricing, Chinese demand and supply disruption from Zimbabwean export controls. The decision also reinforces Australia’s role as a core lithium feedstock supplier to global battery material chains.

Mt Marion lithium expansion includes A$220mn for underground mine development, A$240mn for a flotation plant and A$30mn for non-processing infrastructure. Construction is scheduled to begin in July-September.

The partners expect to commission the mine within 12 months of construction starting, with production ramp-up over the following six months. That timeline makes Mt Marion an important near-term growth project in the Australian hard-rock lithium sector.

Underground Mining Extends Mine Life and Feed Flexibility

The underground mine will supplement ore from the existing open pit and contribute up to 40% of processing feed. This will extend Mt Marion’s remaining mine life by six years beyond the previous estimate of 10 years.

That is strategically important because mine life extension improves supply visibility for customers and investors. Battery chemical producers need stable spodumene feedstock to support long-term lithium hydroxide and lithium carbonate production.

The underground development also gives MinRes and Ganfeng more operational flexibility. Combining open-pit and underground ore can support feed blending, grade control and continuity as the mine matures.

The project will cause minimal disruption to existing operations, according to the company. That matters because the mine is already a major producing asset and any downtime could affect near-term shipments.

Mt Marion is also backed by a strong downstream partner. Ganfeng is one of China’s leading lithium companies, giving the project a direct link to one of the world’s largest battery materials markets.

Flotation Plant Targets Higher-Grade Product Mix

The new flotation plant will remove SC3.5 product from MinRes’ mix and deliver a minimum SC5 grade product. This is a key upgrade because higher-grade concentrate can improve processing efficiency for downstream converters.

SC6 remains the benchmark product for hard-rock lithium supply. Increasing SC6 output to 600,000 t/yr gives Mt Marion stronger exposure to higher-value concentrate markets.

The investment economics are highly sensitive to price. At an assumed SC6 price of $2,700/t, MinRes expects the expansion payback period to be less than one year.

Spodumene prices have risen in recent months, supported by Zimbabwe’s lithium concentrate export controls and strong Chinese demand. The latest Australian SC6 assessment was $2,661/t on 19 May, down from $2,811/t a week earlier but still elevated enough to support renewed investment.

MinRes also cited higher lithium prices as a reason for restarting operations at its Bald Hill mine in Western Australia. Together, these moves suggest producers are again positioning for stronger lithium feedstock demand.

The broader lithium market remains volatile, but the Mt Marion decision shows that high-quality Australian assets can still attract capital when pricing, partners and mine-life extension align.

The Metalnomist Commentary

Mt Marion’s expansion shows that lithium investment is returning first to established, scalable assets with strong downstream links. The key lesson is that the next lithium cycle will reward producers that can improve grade, extend mine life and secure reliable routes into China’s battery supply chain.

Finniss Lithium Operation Restart Signals Australian Spodumene Supply Return

Core Lithium

Finniss Lithium Operation is returning to production after Core Lithium restarted mining at the Grants open pit in Australia’s Northern Territory. The move marks the reopening of an asset that had been in care and maintenance since 2024 because of weak lithium prices.

Finniss Lithium Operation will process its first ore in the September quarter, with the first spodumene concentrate shipment expected in the December quarter. Additional shipments are planned for 2027.

Finniss Lithium Operation restart reflects the sharp recovery in spodumene prices after supply constraints emerged in late 2025. Core Lithium approved the restart in March as stronger pricing improved the economics of bringing idled capacity back online.

The Grants pit will provide access to around 800,000t of ore and deliver about 100,000t of spodumene concentrate on a 5% lithium oxide basis. Mining has started in line with Core Lithium’s final investment decision schedule and cost expectations.

Grants Pit Brings Near-Term Spodumene Back to Market

The Grants open pit gives Core Lithium a near-term route back into the seaborne spodumene market. First ore processing in the September quarter and first shipment in the December quarter create a clear restart timeline.

This matters because Australian lithium producers are beginning to respond to stronger market conditions. Several operations that were halted during the downturn are now restarting as prices recover.

Spodumene prices have rebounded sharply from the lows reached in December 2025. The recovery has made previously idled hard-rock assets more attractive, especially those with existing infrastructure and established development plans.

For buyers, the return of Finniss adds incremental Australian supply at a time when lithium converters are reassessing feedstock security. But the restart also adds new supply into a market still vulnerable to oversupply if too many projects return at once.

Core Lithium’s timing is therefore important. The company is moving before the next wave of supply fully arrives, but it must still prove stable mining, processing and shipment performance after a long shutdown.

BP33 Sets Up Longer-Term Finniss Expansion

Core Lithium is also advancing infrastructure work at the BP33 underground mine. The company awarded a A$274mn underground mining services contract to Develop Global for a three-to-five-year period.

BP33 is expected to be developed by mid-2027. It should help lift ore production at Finniss to 1.2mn t/yr by mid-2028.

Core Lithium’s final investment decision summary outlines a longer-term plan to produce spodumene concentrate over a 20-year mine life. Expected unit costs are around A$762/t, giving the operation leverage to higher spodumene pricing if execution stays on track.

The restart and BP33 development show how lithium producers are rebuilding confidence after the 2024-25 market downturn. The key difference now is that investors and customers will focus more closely on cost discipline, grade, logistics and customer commitments.

For the broader battery supply chain, Finniss adds another signal that Australian spodumene remains central to global lithium raw material supply. The market recovery is bringing supply back, but long-term balance will depend on whether battery demand can absorb returning and new production.

The Metalnomist Commentary

Core Lithium’s restart shows that the lithium cycle has turned enough to bring idled Australian mines back into action. The risk is that recovering prices invite too much supply too quickly, making cost discipline and offtake quality more important than restart headlines.

Australia Northern Minerals Share Sale Order Tightens Control Over Browns Range

Jim Chalmers

Australia Northern Minerals share sale order has renewed scrutiny over foreign ownership of one of the few dysprosium, terbium and yttrium-rich rare earth projects outside China. Australian treasurer Jim Chalmers has ordered five companies and one individual to sell 1.68bn shares in Northern Minerals by 2 July.

Australia Northern Minerals share sale involves 17.6% of the company’s equity, valued at about A$37mn at the latest share price. Most of the parties affected by the order are registered in China or Hong Kong.

Australia Northern Minerals share sale matters because Northern Minerals is developing the Browns Range rare earths mine and concentration plant in Western Australia. The project is expected to produce 5,000 t/yr and is one of the most strategically important heavy rare earth assets in the western supply chain.

The order follows a similar disposal action in 2024, also based on national security concerns. This makes the case more than a shareholder dispute; it is part of Australia’s broader effort to protect critical minerals assets from strategic control risk.

Browns Range Holds Strategic Heavy Rare Earth Value

Browns Range is important because it is rich in dysprosium, terbium and yttrium. These materials are difficult to source outside China and are critical to high-performance permanent magnets.

Dysprosium and terbium help magnets retain performance at high temperatures. That makes them essential for electric vehicles, wind turbines, industrial motors, defence systems, aerospace platforms and advanced electronics.

Northern Minerals is targeting a final investment decision by 30 September. Production is expected to begin in late 2028 to early 2029.

That timeline matters because western manufacturers are trying to build rare earth magnet supply chains before Chinese export controls tighten further. A project like Browns Range could help reduce dependence on China’s heavy rare earth dominance.

But ownership and governance are now central issues. The Australian government clearly wants strategic rare earth assets to remain aligned with national security and allied supply-chain objectives.

The dispute has already involved voting freezes, court proceedings and penalties linked to non-compliance with earlier disposal orders. That shows how sensitive rare earth project control has become.

Allied Funding Raises the Project’s Geopolitical Weight

Browns Range was included in the US-Australian critical minerals joint investment agreement last October. That makes the project part of a wider allied strategy to build resilient rare earth supply chains.

Joint funding of up to $230mn from the US Export-Import Bank and Export Finance Australia was pledged to support the project. This signals that Browns Range is being treated as a strategic supply asset, not only a commercial mine.

The funding also reflects a broader policy shift. Western governments are increasingly using finance, ownership oversight and foreign investment review to shape who controls critical mineral assets.

For Australia, the renewed share sale order reinforces its role as a critical minerals gatekeeper. The country wants foreign investment, but it is drawing a clearer line around assets tied to defence, clean energy and advanced manufacturing.

For rare earth buyers, the decision may improve confidence that Browns Range will remain aligned with western supply-chain security goals. But the legal and shareholder disputes also show that development risk remains high.

The wider market signal is clear. Heavy rare earth projects outside China are becoming too important to leave ownership structure to market forces alone.

The Metalnomist Commentary

The renewed Northern Minerals order shows that heavy rare earths have moved firmly into national security territory. Browns Range is valuable not only because of its geology, but because it could anchor non-China dysprosium and terbium supply for magnets, defence and electrification.

Bald Hill Lithium Mine Restart Signals Stronger Spodumene Recovery

Bald Hill Lithium

Bald Hill lithium mine operations are restarting after Mineral Resources responded to a sustained recovery in lithium prices. The Western Australian mine had been on care and maintenance since November 2024.

Bald Hill lithium mine ramp-up will begin in late May, with crushing and mining operations scheduled to start in June. First spodumene concentrate production is expected in July.

Bald Hill lithium mine shipments are planned from the Port of Esperance in the third quarter of 2026. Full capacity is expected in the fourth quarter.

The restart shows that stronger spodumene prices are beginning to bring suspended Australian lithium capacity back into the market. It also confirms that producers are becoming more confident after the severe lithium downturn that forced project closures and delays.

Spodumene Prices Bring Idled Capacity Back

Bald Hill has production capacity of about 165,000 dry metric tonnes per year of 5.1% spodumene concentrate. On a normalized 6% spodumene concentrate basis, capacity is around 140,000 dmt/yr.

The restart is modest compared with Australia’s largest lithium operations, but it matters for market sentiment. Idled mines returning to production show that the price recovery is no longer only a paper-market signal.

Mineral Resources also operates the Wodgina and Marion lithium mines. The company has lifted production guidance for both assets for the fiscal year ending June 2026.

Wodgina guidance increased to 280,000 dmt of SC6, while Marion guidance rose to 220,000 dmt of SC6. Together with Bald Hill, these assets strengthen MinRes’ position as a major Australian spodumene producer.

The restart also adds more supply to the seaborne lithium concentrate market. That could help converters secure feedstock, but it also raises the risk that returning capacity eventually caps price upside if demand growth slows.

Posco Stake Reinforces Battery Supply Chain Link

South Korean steelmaker Posco acquired a 30% stake in MinRes in November 2025 for $765mn. That investment gives the restart a stronger downstream battery supply-chain connection.

Posco has been expanding across battery materials, and access to Australian spodumene can support long-term lithium chemical production. For MinRes, the relationship provides strategic capital and potential customer alignment.

Western Australia remains one of the world’s most important lithium supply regions. Its hard-rock mines feed converters in China, South Korea and other battery manufacturing hubs.

The Bald Hill restart therefore fits a wider supply-chain pattern. Lithium producers are trying to rebuild volumes as prices recover, while downstream players seek more secure feedstock before battery demand accelerates again.

The key question is whether the recovery remains strong enough to absorb returning supply. If prices hold, more idled lithium capacity could follow Bald Hill back into production.

The Metalnomist Commentary

Bald Hill’s restart shows that lithium’s recovery is becoming operational, not just financial. The market now needs to watch whether returning Australian supply supports battery security or creates the next round of oversupply pressure.

Hancock Lithium Mine Plan Advances as Spodumene Prices Recover

Hancock Lithium Mine

Hancock lithium mine plans in Western Australia are moving forward as stronger lithium concentrate prices revive confidence in large-scale spodumene development. Hancock Prospecting plans to build the A$1bn Andover mine, targeting production of up to 1.1mn t/yr of lithium concentrate.

Hancock lithium mine construction is scheduled to start in November 2028, with a two-year construction period. The project is planned for a 30-year operating life and would process 6mn t/yr of ore.

Hancock lithium mine development reflects a shift in lithium sentiment after the deep price collapse that forced project delays and suspensions across the sector. Spodumene prices have rebounded as Chinese battery demand improves and supply expectations tighten.

The Andover project is strategically important because Australia remains one of the world’s key hard-rock lithium supply bases. New capacity from Western Australia could support converters, battery producers and electric vehicle supply chains seeking long-term spodumene feedstock.

Andover Adds Scale to Western Australia’s Spodumene Pipeline

The Andover mine would become a major new lithium concentrate source if developed as planned. Annual output of up to 1.1mn t would give the project meaningful weight in the seaborne spodumene market.

The project sits within a broader ownership structure shaped by recent consolidation. Hancock Prospecting and Chilean lithium producer SQM partnered to acquire Azure Minerals in a A$1.7bn deal completed in May 2024 through their jointly owned company, SH Mining.

Andover is 60% owned by Azure, while Croydon Gold, a subsidiary of the Creasy Group, holds the remaining 40%. The involvement of Hancock and SQM gives the project both Australian mining strength and global lithium-market experience.

SQM’s role is especially relevant. The Chilean producer brings downstream lithium market knowledge, while Hancock adds financial capacity and Australian project execution capability.

The planned 30-year mine life also matters. Battery supply chains need long-duration feedstock sources, not only short-cycle spot supply. A project of this scale could support long-term offtake and conversion strategies.

Price Recovery Revives Lithium Project Economics

The Andover plan comes after a sharp recovery in spodumene concentrate prices. Prices rose in April as tighter supply expectations followed Zimbabwe’s introduction of export quotas for lithium concentrate.

Spodumene prices had previously collapsed to $900-1,100/t cif China in January 2024, down 83% after supply growth outpaced demand. That downturn forced many lithium developers to slow, delay or reassess projects.

Prices later began recovering in late 2025 as demand from China’s lithium-ion battery sector improved market sentiment. Stronger pricing has now made large hard-rock projects more attractive again.

However, lithium remains a volatile market. New supply from Australia, Africa, South America and China can quickly change balances if demand growth slows or inventories rebuild.

For Hancock, timing will be critical. Construction is not expected to start until late 2028, meaning the project will enter the market after the current price recovery has already been tested by several more years of battery demand and supply growth.

The strategic value remains clear. If lithium demand continues to rise from electric vehicles and energy storage, Andover could become an important feedstock source for global converters. If supply again expands too quickly, project economics may face renewed pressure.

The Metalnomist Commentary

Hancock’s Andover plan shows that lithium investment confidence is returning, but only for projects with scale, strong sponsors and long-term strategic value. The market has recovered from its deepest downturn, but future winners will still need cost discipline and secure downstream demand.

Sibanye PGM Production Rises in South Africa as US Output Falls

Sibanye

Sibanye PGM production improved in South Africa during the first quarter, but the company’s US mine output weakened because of lower production quality at East Boulder. The mixed result highlights the company’s uneven exposure across primary mining, recycling, zinc and lithium.

Sibanye PGM production in South Africa rose by 2% year on year to 383,241oz of 4E metals, covering platinum, palladium, rhodium and gold. Growth projects supported the increase and helped keep the company on track with its full-year guidance.

Sibanye PGM production in the US moved in the opposite direction. Output of 2E metals, covering platinum and palladium, fell by 5% to 68,386oz, with regular production expected to resume by the end of June.

The company maintained full-year guidance for both regions. South African operations are expected to produce 1.65mn-1.75mn oz, while US operations remain guided at 280,000-300,000oz.

South African Growth Offsets US Mine Weakness

Sibanye’s South African PGM operations remain the stronger side of the portfolio. The 2% increase in first-quarter output shows that ongoing growth projects are helping offset broader pressure across the PGM sector.

This matters because South Africa remains the world’s most important primary PGM supply base. Stable output from large producers supports automotive catalysts, hydrogen technologies, chemicals, electronics and industrial applications.

The US Stillwater operations faced a weaker quarter. Lower production quality at East Boulder reduced output, although Sibanye expects normal production to return by the end of June.

The US decline is important because North American primary PGM supply is limited. Any disruption at Stillwater assets can affect regional availability of palladium and platinum, especially for customers seeking non-Russian and traceable supply.

Recycling helped offset the weaker US mine performance. Sibanye’s US recycled PGM output rose by 50% to 107,597oz, supported by better optimisation of material flows.

That increase reinforces the strategic value of secondary supply. PGM recycling can provide flexible metal units when mine output is uneven, while also supporting lower-carbon and circular supply chains.

Zinc Weakness and Keliber Progress Broaden the Portfolio Story

Sibanye’s Australian Century zinc operation produced 20,000t in the first quarter, down by 25,000t from a year earlier. Above-average rainfall reduced capacity and operating flexibility at the zinc operation.

The decline shows the weather sensitivity of tailings and zinc operations. Heavy rainfall can affect mining rates, processing efficiency, transport and operating continuity.

Century’s weaker output also matters because zinc remains important for galvanizing steel, infrastructure, construction, die casting and industrial manufacturing. Lower production from a major operation can tighten regional supply if weather disruption persists.

Meanwhile, Sibanye’s Keliber lithium project in Finland reached full completion during the first quarter. The first mining blast took place at the Syvajarvi mine in February.

Keliber gives Sibanye a strategic entry into Europe’s lithium supply chain. The project connects the company to battery materials demand and supports Europe’s effort to build more domestic critical mineral capacity.

Sibanye’s portfolio is therefore becoming more diversified. PGMs remain the core earnings and strategic base, but recycling, zinc and lithium all add exposure to different industrial cycles.

The first-quarter results show the benefits and risks of that structure. South African PGMs and US recycling improved, US mine output weakened, zinc suffered weather disruption, and lithium moved closer to future production.

The Metalnomist Commentary

Sibanye’s quarter shows why diversified metals exposure can protect a company from single-asset weakness, but also adds execution complexity. The strongest strategic signal is the rise in recycled PGM output, which could become increasingly valuable as customers seek secure and lower-carbon platinum and palladium supply.

Liontown Lithium Production Holds Flat as Kathleen Valley Shifts Underground

Liontown

Liontown lithium production was flat in January-March as the Kathleen Valley operation completed its first full quarter as a fully underground mine. The Australian miner produced 96,000t of spodumene concentrate during the quarter, unchanged from a year earlier but down 9% from the previous quarter.

Liontown lithium production is now being reshaped by the transition away from previously mined open-pit ore toward underground feed. The shift is important because underground ore is expected to support more stable grades and recoveries as Kathleen Valley moves deeper into its long-term operating model.

Liontown lithium production also faced shipment disruption from tropical cyclone Narelle, which temporarily affected port operations at Geraldton in Western Australia. Two shipments were delayed, including one that was deferred into early April.

The quarter shows a lithium producer moving through a technical transition rather than a demand-led slowdown. Kathleen Valley is still ramping toward its longer-term target of around 500,000 t/yr of spodumene concentrate.

Underground Feed Improves Recovery Outlook

Kathleen Valley’s underground mining performance improved during the quarter. Underground ore mined totalled 402,000t, up 31% from the previous quarter, with an average grade of about 1.4% lithium oxide.

Lithia recoveries improved in late March as underground ore became the dominant feed source. Liontown achieved its 70% recovery target, while underground ore accounted for 67% of the feed mix in the first weeks of April.

This is a key operational milestone. As the feed mix shifts away from open-pit stockpiles, Kathleen Valley should gain better consistency in processing performance, grade control and recovery rates.

However, the transition also affected quarterly output. Lower production volumes and variable recoveries pushed unit operating costs higher, showing that underground ramp-up periods can create temporary cost pressure before stable-state performance is reached.

Kathleen Valley has a 2.8mn t/yr mining capacity and is expected to produce around 500,000 t/yr of spodumene concentrate. Reaching that level will depend on sustained underground ore delivery, process stability and shipment execution.

Port Disruption and Cost Pressure Shape Near-Term Performance

Cyclone-related disruption affected sales during the quarter. Tropical cyclone Narelle interrupted operations at Geraldton for several days in March, delaying two shipments.

Liontown ended the quarter with 26,270 dry metric tonnes of concentrate in inventory. This was up from 13,800dmt in the previous quarter and 22,519dmt a year earlier, partly reflecting shipment timing.

Unit operating costs on a fob sales basis rose to A$981/t from A$910/t in the previous quarter. The increase was driven by lower production volumes and recoveries during a period of variable feed mix.

This cost movement matters because lithium markets remain highly competitive after the price correction of the past two years. Producers need scale, grade control and low operating costs to defend margins.

Kathleen Valley’s underground transition could improve cost performance over time if recoveries remain stable and mined volumes continue rising. But the quarter shows that ramp-up execution remains critical.

For the wider lithium market, Liontown’s flat output adds to a more disciplined supply picture. New spodumene supply is still entering the market, but operational transitions, weather disruptions and cost pressure continue to affect how quickly nameplate capacity becomes reliable production.

The Metalnomist Commentary

Liontown’s quarter should be read as an underground ramp-up story, not a weak demand signal. Kathleen Valley’s recovery performance is improving, but cost control and shipment reliability will determine how competitive the operation becomes as lithium supply remains under pressure.

Critical Metals Tanbreez Acquisition Consolidates Greenland Rare Earth Control

Critical Metals

Critical Metals Tanbreez acquisition will give the US critical minerals developer full ownership of one of Greenland’s most closely watched rare earth projects. The company has agreed to acquire Australian mining firm European Lithium in an all-stock deal valued at $835mn.

The Critical Metals Tanbreez acquisition is designed to consolidate ownership of the Tanbreez rare earth project, where European Lithium currently holds a 7.5% stake. Completion of the transaction would give Critical Metals 100% ownership.

The Critical Metals Tanbreez acquisition strengthens the company’s position in the race to build rare earth supply chains outside China. Greenland is becoming strategically important because western governments and manufacturers want new sources of rare earth concentrate tied to secure processing and offtake routes.

European Lithium shareholders would receive 0.035 Critical Metals shares for each European Lithium share under the letter of intent. The proposed transaction is expected to close in the second half of 2026.

Tanbreez Ownership Supports Mine-to-Market Strategy

Full ownership of Tanbreez would give Critical Metals greater control over project development, financing, offtake and downstream strategy. This matters because rare earth projects often struggle when ownership, processing and customer structures are fragmented.

Critical Metals plans to invest $30mn to fast-track development of Tanbreez. That investment signals an effort to move the project beyond resource positioning and toward a more commercial supply-chain role.

Tanbreez could become an important source of rare earth concentrate for non-China buyers. However, concentrate alone is not enough to secure the rare earth value chain. Material must still be separated, refined, converted into metals or alloys, and qualified by downstream users.

The company’s offtake agreements provide early commercial direction. Critical Metals has an agreement with Ucore Rare Earths for as much as 10,000 t/yr of rare earth concentrate and another with REalloy for 15% of Tanbreez’s annual output.

These agreements help anchor future sales channels. They also show that buyers are willing to secure upstream access before full project development is complete.

Saudi Processing Plan Adds Downstream Dimension

Critical Metals also plans to form a joint venture in Saudi Arabia to build a rare earth processing facility. This is strategically important because processing capacity remains the key bottleneck in ex-China rare earth supply chains.

A Greenland-to-Saudi processing route would add a new geopolitical configuration to the rare earth market. It would connect western-controlled resources with Middle Eastern industrial investment and processing ambitions.

Saudi Arabia has been seeking a larger role in critical minerals, downstream processing and industrial diversification. A rare earth processing venture would fit that strategy while giving Critical Metals another route to move beyond concentrate sales.

For global rare earth buyers, the key issue will be reliability. They need traceable feedstock, qualified processing, stable offtake and predictable geopolitical access.

The transaction also reflects a wider industry trend. Rare earth companies are consolidating ownership and building downstream partnerships because customers no longer want isolated mining assets. They want integrated supply chains that can deliver usable material.

Critical Metals’ strategy is therefore not only about acquiring European Lithium. It is about controlling Tanbreez, securing offtake, adding processing optionality and positioning the project as part of an ex-China rare earth supply network.

The Metalnomist Commentary

The Critical Metals Tanbreez acquisition shows that rare earth strategy is shifting from exploration ownership to full supply-chain control. The real test will be whether Greenland feedstock, Saudi processing and offtake agreements can become a bankable alternative to China-dominated rare earth flows.

Lopal Marble Bar Lithium Project Deal Extends Chinese Battery Material Supply Strategy

Lopal

Lopal Marble Bar lithium project acquisition will give China’s battery cathode material producer Lopal Tech another upstream position in Western Australia’s lithium sector. The company has agreed to acquire the Marble Bar project from Global Lithium Resources for A$14.85mn.

The Lopal Marble Bar lithium project is located in the Pilbara region of Western Australia. The project has an estimated resource of 18mn t grading 1.0% lithium oxide.

The Lopal Marble Bar lithium project deal reflects a continuing push by Chinese battery material producers to secure upstream lithium resources. Cathode and battery material companies are looking beyond processing capacity and moving closer to mine supply.

This matters because lithium raw material security remains central to battery supply chains. Even as lithium prices fluctuate, companies with long-term access to spodumene resources can better protect conversion plants, cathode output and customer supply.

Marble Bar Adds Pilbara Resource Exposure

The Marble Bar project gives Lopal direct exposure to a known lithium-bearing region. Western Australia remains one of the world’s most important hard-rock lithium supply bases, with spodumene projects feeding converters and battery material producers across Asia.

The project’s 18mn t resource at 1.0% lithium oxide gives Lopal a potential raw material position, although the acquisition price suggests the asset is still at an early development stage.

For Global Lithium Resources, the sale allows the company to focus more heavily on its larger Manna lithium project. Manna has a resource estimate of 52mn t grading 1.0% lithium oxide.

This creates a clearer portfolio structure. Lopal gains Marble Bar, while GL1 retains its larger Manna asset and existing downstream-linked partnerships.

The transaction also shows that Chinese battery material producers remain willing to invest in Australian lithium assets despite market volatility. Long-term supply security continues to matter more than short-term price weakness.

Manna Links Lopal to Future Offtake Supply

Lopal already has exposure to GL1 through the Manna project. It holds a 5% equity interest in Manna and has signed an offtake agreement to buy 40% of the project’s output.

China’s Canmax has agreed to take another 30% of Manna’s output and also holds a 9.45% stake in GL1. Australian lithium miner Mineral Resources owns 9.85% of GL1.

These relationships show how lithium supply chains are being structured around equity stakes and offtake agreements. Battery material companies want secured feedstock before projects enter production.

For Lopal, the Marble Bar acquisition adds another layer to its Australian lithium strategy. It gives the company project ownership while maintaining future offtake exposure through Manna.

The broader industrial meaning is clear. Chinese battery material producers are not relying only on spot markets. They are building upstream positions, offtake rights and strategic relationships to support long-term lithium chemical and cathode material supply.

The Metalnomist Commentary

Lopal’s Marble Bar deal shows that lithium strategy is shifting from price speculation to resource control. Even in a weaker lithium market, Chinese battery material companies continue to secure upstream positions that can support future conversion and cathode supply.

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.

Rio Tinto Copper Output Rises as Oyu Tolgoi Offsets Lithium Weakness

Rio Tinto

Rio Tinto copper output increased in the first quarter as stronger production from the Oyu Tolgoi mine in Mongolia lifted the group’s global copper performance. The UK-Australian miner produced 229,000t of consolidated copper in January-March, up 9% from a year earlier.

Rio Tinto copper output growth was driven mainly by copper in concentrates from Oyu Tolgoi, where production rose by 56% to 102,000t. The ramp-up helped offset weaker concentrate output at Escondida and lower refined copper production at Kennecott.

The first-quarter result shows the changing shape of Rio Tinto’s portfolio. Copper is gaining strategic weight as electrification, grids and industrial infrastructure support long-term demand, while lithium remains more exposed to weather, ramp-up timing and early-stage project execution.

At the same time, Rio Tinto reported higher alumina production but weaker bauxite and lithium output. Heavy rainfall and cyclone-related disruptions affected Australian bauxite mines, while weather events in Argentina reduced lithium carbonate equivalent production.

Copper Growth Strengthens Despite Mixed Mine Performance

Oyu Tolgoi was the strongest contributor to Rio Tinto copper output in the first quarter. Its continued ramp-up in Mongolia lifted copper in concentrates production to 102,000t, reinforcing the mine’s role as one of the group’s most important growth assets.

The result matters because large copper projects are increasingly difficult to bring into stable production. Oyu Tolgoi gives Rio Tinto a major long-life copper source at a time when global mine supply remains vulnerable to grades, permitting delays and operational disruptions.

Escondida delivered a mixed quarter. Refined copper output at the Chilean operation rose by 21% to 16,000t, but concentrates production fell by 14% to 77,000t.

Kennecott in the US was weaker. Refined copper production fell by 20% to 34,000t because of lower anode inventories after unplanned smelter maintenance and reduced concentrator throughput caused by geotechnical constraints.

Rio Tinto kept its full-year copper production guidance unchanged at 800,000-870,000t. This suggests the company sees first-quarter disruptions as manageable within its broader 2026 plan.

The company also began drilling at the Resolution Copper project in Arizona after completing the land exchange in March. Resolution remains strategically important because it could become a major US copper source if development advances.

Rio Tinto copper output therefore carries both short-term and long-term significance. Oyu Tolgoi is already lifting production, while Resolution represents future supply optionality in a market increasingly focused on domestic and allied copper sources.

Lithium Falls as Weather Disrupts Argentina Operations

Rio Tinto’s lithium performance weakened sharply in the first quarter. Attributable lithium carbonate equivalent production fell by 26% on the year to 12,700t.

The decline was caused by heavy rainfall and weather events that disrupted operations at Olaroz and Fenix in Argentina. These disruptions show that lithium brine and carbonate operations remain sensitive to weather, water balance and site logistics.

The continued ramp-up at the Rincón starter plant partly offset the production impact. Rincón is important for Rio Tinto’s lithium strategy because it supports the company’s expansion into battery materials.

Rio Tinto maintained its 2026 LCE production guidance at 61,000-64,000t. First production from Fenix 1B and Sal de Vida remains on track for the second half of 2026.

The aluminium chain also showed mixed results. Primary aluminium output rose by 1% on the year to 835,000t, but fell by 2% from the previous quarter.

Alumina production increased by 6% to 2.04mn t, while bauxite production fell by 11% to 13.28mn t. Heavy rainfall at Weipa in Queensland and cyclone-related shutdowns at Weipa and Gove reduced bauxite output.

Recycled aluminium production also fell by 8% to 61,000t. Rio Tinto kept 2026 guidance unchanged for primary aluminium, alumina and bauxite, indicating confidence in recovery through the year.

The first-quarter data show a portfolio with different operating pressures. Copper is benefiting from major mine ramp-up, lithium is facing weather disruption, and aluminium raw materials are exposed to Australian climate events.

The Metalnomist Commentary

Rio Tinto’s first quarter shows why diversified miners need both growth assets and operational resilience. Oyu Tolgoi is strengthening Rio Tinto copper output, but weather-linked lithium and bauxite disruptions show that energy-transition supply chains remain exposed to physical operating risk.
