Guinea revokes EGA’s bauxite mining licence in high-stakes reshuffle

EGA(Emirates Global Aluminium)

Guinea revokes EGA’s bauxite mining licence amid a sweeping sector reset and assigns the permit to state-owned Nimba Mining. The move places exports, investment confidence, and alumina feedstock security under scrutiny. As a result, Guinea revokes EGA’s bauxite mining licence becomes a pivotal test for West Africa’s bauxite supply chain.

Licence revoked and reassigned to Nimba Mining

Guinea completed the revocation process and transferred rights to Nimba Mining. Authorities first halted GAC shipments in October over refinery delays. The decision aligns with a broader rollback of more than 50 mining licences. However, Guinea revokes EGA’s bauxite mining licence at a time of fragile alumina margins. EGA denounced the action as an illegal expropriation and will pursue legal remedies.

Supply chain and legal implications for bauxite and alumina

GAC became a top third-party bauxite supplier after launching in 2019. It shipped to Vedanta, Bosai, and Xinfa under multi-year deals. Output fell 23pc to 10.8mn t in 2024 after suspensions. Therefore, alumina refineries may rebalance cargoes toward Australia and Guinea peers. The reassignment could also redirect Guinean volumes through a new state-led channel.

Investor risk rises as contract sanctity faces a public test. Multinationals may seek political risk cover and tighter stabilization clauses. Meanwhile, EGA signaled diversification by exploring bauxite options in Ghana. Ghana’s resources exceed 900mn t, which could buffer medium-term supply risk. Even so, near-term dislocation may widen freight spreads and lift FOB premia.

Project execution now hinges on Nimba Mining’s ramp-up and financing. Port, rail, and mine interfaces must maintain exported quality and cadence. Otherwise, buyers will demand alternate origin cargoes or renegotiate terms. Market participants will track Guinea’s permitting cadence and dispute timelines. Compliance, ESG, and in-country beneficiation will shape future approvals.

The Metalnomist Commentary

Guinea’s intervention reshapes bauxite bargaining power toward the state. Expect tighter local-processing obligations and more stringent timelines. Short term, traders may price higher origin risk into 2025 contracts while watching EGA’s legal path.

Guinea Mining Licences Revocation Affects 50+ Operations Amid Resource Nationalism

Guinea Mining

Guinea mining licences revocation encompasses more than 50 permits granted over the past two decades, targeting bauxite, iron ore, gold, diamond, and graphite operations. The Guinea mining licences cancellation decree signed by interim president Mamady Doumbouya focuses on non-operational projects and underutilized permits, reflecting broader resource nationalism trends across West Africa's military-controlled governments.

Military Government Targets Underperforming Mining Assets

Guinea mining licences repossession primarily affects operations that failed to launch or demonstrate inadequate utilization of granted permits. Information Minister Fana Soumah announced the comprehensive review during a television address, emphasizing the government's commitment to maximizing resource development outcomes. The decree represents the most significant mining sector intervention since Doumbouya's military takeover in September 2021.

Meanwhile, industry analysts indicate the revocations predominantly target non-operating assets rather than active mining operations. This selective approach suggests the military government seeks to optimize resource allocation without disrupting established production and export revenues. The strategy aligns with similar resource nationalism policies implemented across West African nations following recent military coups.

EGA Bauxite Operations Face Specific Scrutiny

However, the announcement follows earlier reports that Guinea initiated proceedings to revoke Emirates Global Aluminium's (EGA) bauxite mining licence. EGA's Guinea Alumina subsidiary ranks as the world's second-largest bauxite supplier to third parties, making this potential revocation particularly significant for global aluminum supply chains. The government cited delays in EGA's planned alumina refinery construction as justification for the licence review.

Therefore, the EGA case exemplifies the military government's emphasis on value-added processing rather than raw material exports. Guinea's leadership demands concrete progress on downstream development commitments made during original licence negotiations. This policy shift reflects broader African resource governance trends prioritizing local beneficiation over traditional commodity export models.

Regional Context Shapes Mining Sector Uncertainty

Furthermore, Guinea's actions mirror resource nationalism patterns across West Africa following military takeovers in Niger, Burkina Faso, and Mali over the past five years. These governments consistently challenge existing mining agreements while demanding greater local content and processing requirements. The coordinated approach suggests regional alignment on extractive industry governance despite distinct national circumstances.

As a result, Guinea faces pressure to restore democratic governance by year-end when the transition period established by the military junta and regional bloc ECOWAS expires. Scheduled elections create additional uncertainty for mining sector investors navigating both political transitions and evolving resource policies. The timing of licence revocations before democratic restoration raises questions about continuity of mining sector reforms.

The Metalnomist Commentary

Guinea's comprehensive mining licence revocation demonstrates how resource nationalism increasingly shapes African mining governance, particularly following military interventions that prioritize sovereignty over foreign investment partnerships. The selective targeting of underperforming assets while maintaining active operations suggests a pragmatic approach to resource optimization, though the EGA case highlights risks for major international mining companies operating in politically unstable environments.

Zangge Mamicuo lithium project secures mining licence in Tibet

Mamicuo Li

Zangge Mamicuo lithium project secured a mining licence in Tibet. The approval clears a path to salt-lake production. Zangge Mamicuo lithium project now targets a 50,000 t/yr first phase. Therefore, Zangge Mamicuo lithium project advances toward near-term construction.

Licence scope and resources

The licence covers 115.36km² and includes lithium, boron, and potassium. Proven resources total 2.1774mn t LCE. Zangge holds a 26.95% stake in the asset. The permit was issued on 15 July and runs to 30 April 2030.

Build plan, power needs, and portfolio moves

Zangge will start constructing a 50,000 t/yr lithium carbonate plant in Q3. Construction should take nine to twelve months. Phase two adds 50,000–80,000 t/yr after full ramp. However, power reliability will determine second-phase timing. Meanwhile, Zangge produces lithium carbonate at Qarhan, with 2024 output of 11,566t. The company plans stakes in Jiezechaka and Longmucuo projects. It will acquire 39% of Tibet Guoneng Mining for 4.68bn yuan. As a result, integrated assets could strengthen China’s battery materials supply.

The Metalnomist Commentary

This licence elevates Tibet’s role in China’s brine-based lithium strategy. Execution now hinges on power stability and brine processing performance. Watch phase-two timing, capex discipline, and offtake alignment with cathode makers.

EGA Guinea Bauxite Supply Deal Restores Route to UAE Alumina Operations

Bauxite

EGA Guinea bauxite supply has moved closer to normalisation after Emirates Global Aluminium reached an amicable settlement with Guinea over the revocation of its bauxite mining licence. The agreement will allow Guinean producer CBG to resume bauxite shipments to EGA’s operations in the UAE.

EGA Guinea bauxite supply had been disrupted since Guinean customs suspended shipments from EGA subsidiary Guinea Alumina in October 2024. The suspension followed delays in EGA’s plan to build an alumina refinery in Guinea.

EGA Guinea bauxite supply became more uncertain in 2025 when Guinea revoked EGA’s bauxite mining licence and reassigned it to newly created state-owned firm Nimba Mining. GAC continued to seek redress through legal action before the latest settlement.

The agreement includes a lump-sum payment by Guinea to GAC for the transfer of assets to Nimba Mining. It also renews EGA’s bauxite supply agreements with CBG under mutually beneficial commercial terms.

Guinea Settlement Reopens a Strategic Bauxite Channel

The settlement is important because Guinea is one of the world’s most important bauxite supply sources. Its high-volume export role makes it central to alumina refineries and integrated aluminium producers.

For EGA, access to Guinean bauxite supports feedstock security for its Al Taweelah alumina refinery in the UAE. Stable bauxite supply is essential because alumina production depends on consistent ore quality, logistics and long-term commercial arrangements.

The dispute also shows how resource nationalism is reshaping aluminium raw material supply. Guinea has been pushing for more domestic value creation and stronger state control over mining assets.

The revocation of EGA’s licence formed part of a broader review of more than 50 mining licences granted over the past two decades. Those licences covered bauxite, iron ore, gold, diamonds and graphite.

By transferring assets to Nimba Mining while renewing supply through CBG, Guinea preserves more state influence while allowing trade with EGA to resume. This gives both sides a practical route out of a prolonged dispute.

For the wider aluminium market, the settlement reduces one layer of uncertainty around bauxite flows. However, it also reinforces the need for producers to manage political risk in key mining jurisdictions.

Hormuz Disruption and Smelter Damage Still Cloud Recovery

The bauxite agreement does not immediately remove all operational risk for EGA. The resumption of shipments to Al Taweelah depends on the reopening of the Strait of Hormuz, which has been disrupted by the US-Israel and Iran war.

This adds a logistics risk to the feedstock recovery. Even with commercial terms resolved, bauxite and alumina supply chains still depend on safe shipping routes through one of the world’s most strategic maritime chokepoints.

EGA is also dealing with damage at its Al Taweelah aluminium smelter after a missile attack on 28 March. Operations there could take a year to resume, creating a separate challenge for the company’s primary aluminium output.

The situation highlights the dual exposure of integrated aluminium producers. They need secure upstream bauxite and alumina supply, but they also need reliable power, smelter operations and shipping routes.

For EGA, the Guinea settlement is a major positive for raw material continuity. But the company’s near-term recovery will still depend on geopolitical stability, shipping access and the pace of repairs at Al Taweelah.

The broader industrial message is clear. Aluminium supply security now depends on more than ore availability. It requires political settlement, maritime access, energy security and resilient smelting infrastructure.

The Metalnomist Commentary

EGA’s settlement with Guinea shows that bauxite supply is becoming a political asset, not just a mining contract. The deal restores an important feedstock route, but Hormuz disruption and Al Taweelah damage show how fragile integrated aluminium supply chains have become.

Guinea State-Owned Mining Company Nimba Reshapes Bauxite Strategy

Nimba Mining

Guinea state-owned mining company Nimba Mining has begun operations, marking a decisive shift in national resource control. The new entity anchors the Simandou Vision 2040 strategy and immediately enters the seaborne market with bauxite exports. As a result, Guinea state-owned mining company ambitions are now tied directly to both sovereignty goals and global aluminium supply chains.

Nimba Mining takes over Tinguilinta and first bauxite exports

Nimba Mining operates the Tinguilinta deposit, one of Guinea’s largest bauxite resources, giving it instant scale and relevance. The company has already shipped its first 200,000t of bauxite through the Kamsar export terminal. This early cargo demonstrates operational readiness and signals that Nimba will compete with established private and foreign-backed miners.

Guinean officials frame the launch as a reclaiming of control over strategic minerals and mining rents. The government expects the Guinea state-owned mining company model to professionalise the sector while retaining more value onshore. As a result, foreign partners will increasingly interact with Nimba as a central counterparty in bauxite and future iron ore projects.

Alumina ambitions and licence shock for foreign investors

Authorities plan to pair Nimba’s bauxite production with domestic alumina refineries to boost value-added processing in Guinea. Local refining capacity would reduce raw ore exports and capture more downstream margins in the aluminium value chain. However, such plans will require major capital, stable power supply and long-term offtake agreements.

Nimba received the bauxite licence previously held by Emirates Global Aluminium after that concession was revoked. The decision followed delays in EGA’s alumina refinery project, which Guinea viewed as a failure to deliver promised industrialisation. EGA has condemned the move as an “illegal and hostile takeover” and is pursuing legal redress for what it calls de facto expropriation.

Simandou Vision 2040 and growing resource nationalism

The Simandou Vision 2040 programme positions mining as the backbone of Guinea’s long-term economic development. Within this framework, the Guinea state-owned mining company Nimba is designed to be a flagship national champion. Its mandate spans bauxite, iron ore and gold, linking bulk commodities and higher-value metals under one state-controlled platform.

However, the licence transfer from a major Gulf investor will heighten perceived sovereign and contract risk. International miners and aluminium producers may demand tougher guarantees or political risk cover before committing new projects. At the same time, governments and traders reliant on Guinean bauxite must adapt to a landscape where state-controlled marketing gains influence.

The Metalnomist Commentary

Nimba’s launch underscores how producer countries are tightening their grip on critical mineral value chains. For buyers of Guinean bauxite, the rise of a Guinea state-owned mining company brings both coordination benefits and sharper political risk. Over the next decade, Simandou-linked projects and alumina investments in Guinea will become a key barometer for resource nationalism and supply security in the aluminium market.

Kvanefjeld Rare Earth Project Faces Licence Renewal Rejection in Greenland

Kvanefjeld Rare Earth Project

Kvanefjeld rare earth project development faces another major setback after Energy Transition Minerals said Greenland’s government may reject the renewal of its exploration licence. The Australian explorer said the draft decision indicates that further exploration may no longer serve a purpose under the current legal framework.

The Kvanefjeld rare earth project contains significant neodymium and praseodymium resources. ETM has reported a mineral resource estimate of 1.14mn t of contained rare earth oxides, making the project one of the more visible rare earth deposits in the North Atlantic region.

The possible rejection matters because neodymium and praseodymium are key inputs for permanent magnets used in electric vehicles, wind turbines, robotics, defense systems, and advanced industrial equipment. However, the project remains constrained by Greenland’s uranium restrictions.

Uranium Content Remains the Central Legal Barrier

Greenland’s draft decision relies on Parliament Act No. 20 of December 2021, commonly referred to as the 2021 Uranium Act. The law restricts mining projects if the average uranium content in the total resource exceeds 100 parts per million.

ETM said the Kvanefjeld ore body has uranium content of 360ppm. This places the project well above the threshold and creates a legal barrier to any future exploitation licence under Greenland’s current framework.

The government’s position is that exploration activity may no longer be useful if the project cannot proceed to mining. That makes the exploration licence renewal more than an administrative issue; it directly tests whether Kvanefjeld rare earth project development can remain alive under existing law.

Legal Dispute Adds Risk to Greenland’s Rare Earth Strategy

ETM is already pursuing legal action against the Greenland and Danish governments for alleged breach of contract. The company is seeking $7.5bn in damages and $4bn in pre-award interest for losses connected to the project’s development since 2007.

The dispute highlights a wider tension in critical minerals policy. Greenland holds rare earth potential, but environmental, political, and radioactive by-product concerns can restrict project development even when the mineral resource is strategically valuable.

ETM said it is engaging with Greenlandic authorities and will respond to the draft decision. For the market, the key issue is whether Kvanefjeld remains a stranded rare earth resource or whether any legal, political, or regulatory path can reopen future development.

The Metalnomist Commentary

The Kvanefjeld rare earth project shows that critical mineral security is not only about resource size. Uranium content, local legislation, and political acceptance can decide whether even a globally significant rare earth deposit becomes supply or remains locked underground.

Chile lithium mining license moves forward under private–indigenous JV model

Chile lithium mining

Chile lithium mining license dynamics are shifting as a private–indigenous joint venture moves first in the new Ollagüe process. The Chile lithium mining license application was filed by Kuska Minerals, a JV between Canada’s Wealth Minerals and the Quechua Indigenous Community of Ollagüe. The Chile lithium mining license bid positions Kuska as an early mover in a basin that the government already classed as high potential in 2024. By partnering with the CIQO, Wealth aligns directly with Chile’s requirement for agreements with affected native communities. This structure also helps the company streamline its own consultation process while offering the community a 5pc equity stake in future value.

Indigenous partnership reshapes Ollagüe lithium approvals

Chile now places indigenous consultation at the centre of lithium approvals, and the Ollagüe salt flat shows how this works in practice. Authorities recently completed native consultations that remapped the exploitable area to protect culturally sensitive zones and populated areas. As a result, the mining ministry opened a fresh application round focused on the remaining brine resources. Kuska is, so far, the only bidder to publicly submit an official application for this high-altitude basin. The JV is now verifying that it meets every technical and legal criterion and has committed to comply fully before the undisclosed deadline. This early alignment with both state and community expectations should reduce project risk if the license advances to the next stage.

Faster licensing supports Chile’s lithium expansion strategy

Chile is using a streamlined process in Ollagüe to accelerate lithium supply while preserving regulatory control. Officials expect the new licensing window to move relatively quickly, signalling to investors that administrative reforms are starting to bite. At the same time, the country has already approved seven other lithium-related permits this year, including projects linked to Eramet, a JV with Quiborax and Codelco, and two Rio Tinto applications. These approvals affirm Chile’s intent to turn selected salars into bankable projects, rather than leaving resources stranded amid policy debate. For downstream battery and EV supply chains, the Ollagüe basin could become another node in a diversified, ESG-sensitive lithium portfolio if Kuska’s bid succeeds.

The Metalnomist Commentary

Kuska’s structure shows how future lithium developers in Chile may need to blend foreign capital, state oversight and genuine indigenous participation. If this model delivers both social licence and predictable approvals, it could become a template for other high-potential salars. Global buyers should watch Ollagüe closely, as community-anchored licensing could shape both cost structures and long-term offtake security.

Indonesia nickel mine suspensions highlight tighter ESG enforcement and supply risk

Indonesia Nickel Mine

Indonesia nickel mine suspensions in southeast Sulawesi underline Jakarta’s tougher stance on reclamation and post-mining responsibilities. The Ministry of Energy & Mineral Resources (ESDM) has halted operations at 25 nickel mines over missing reclamation and post-mining guarantees. Indonesia nickel mine suspensions now sit within a broader crackdown that also targets coal, gold, iron ore, tin and asphalt producers across several provinces.

Indonesia nickel mine suspensions tied to reclamation failures and permit gaps

Indonesia nickel mine suspensions follow months of warning letters issued between December 2024 and August 2025. Regulators moved only after companies failed to respond with compliant reclamation plans and financial guarantees. The 25 affected nickel operators in southeast Sulawesi join a wider list of 190 suspended general mining licences from central Kalimantan to north Maluku.

However, the sanctions are temporary and may last up to 60 days if companies act quickly. Suspended firms must continue site maintenance, environmental management and monitoring to limit further damage. The ESDM has also sent suspension notices to some nickel mines in north Maluku, signalling that enforcement will not stay confined to one region. As a result, miners now face clear pressure to treat reclamation, guarantees and forestry permits as core licence conditions, not paperwork.

The Indonesia nickel mine suspensions add to recent high-profile actions by a government taskforce. Earlier this month, authorities seized land from Weda Bay Nickel and Tonia Mitra Sejahtera for lacking forestry permits. That decision pushed LME official nickel prices up by about 3pc on 15 September, underscoring how governance interventions can move global benchmarks. Traders now read enforcement news almost as closely as ore shipment updates.

Market impact limited today, but ore supply concerns are building

The immediate market impact from the Indonesia nickel mine suspensions appears modest. Some sanctioned operations were inactive or had unstable output, according to market participants. Three-month LME class 1 nickel prices were largely rangebound at the time of the announcement, with only minor intraday moves.

However, the cumulative effect of licence suspensions, land seizures and stricter forestry compliance is beginning to worry ore buyers. Indonesia remains the world’s dominant supplier of nickel ore and nickel units for stainless steel and battery precursors. Therefore, even small disruptions can tighten margins for NPI smelters and high-nickel battery material producers already facing narrow spreads.

Downstream, stainless steel and battery supply chains now need to factor regulatory risk into feedstock strategies. Some buyers may diversify towards the Philippines or consider higher use of recycled nickel where possible. But substitution options remain limited at scale, keeping Indonesia at the centre of nickel supply planning for the foreseeable future.

The Metalnomist Commentary

Indonesia’s nickel strategy is clearly shifting from volume-at-all-costs to stricter licence discipline and ESG alignment. For miners and smelters, the new reality is that reclamation guarantees and forestry permits sit on the same level as ore grades and cash costs. Policy risk in Indonesia is becoming a structural driver of nickel prices, not just an occasional headline shock.

Kenmare Moma Titanium Minerals Mine Cuts Workforce as Mineral Sands Market Weakens

Kenmare Resources

Kenmare Moma Titanium Minerals Mine is facing a sharper restructuring phase as Kenmare Resources moves to cut 15% of the workforce at its Moma complex in Mozambique. The decision reflects weaker mineral sands market conditions, lower projected revenues, and pressure from operational setbacks during 2025.

The company also suspended its 2025 final dividend and booked a $301.1 million impairment charge. Kenmare linked the impairment to an uncertain pricing outlook and updated assumptions around the renewal terms of Moma’s mining licence with Mozambique’s government.

Kenmare Moma Titanium Minerals Mine produces heavy mineral concentrates including ilmenite, zircon, and rutile. These materials supply titanium dioxide pigment, ceramics, welding, and titanium feedstock markets, making Moma an important asset in the global mineral sands chain.

WCP A Commissioning Issues Hit Production and Cash Flow

Kenmare’s 2025 results were heavily affected by the Wet Concentrator Plant A upgrade at Moma. The project drove capital spending higher, while commissioning problems reduced production volumes and limited sales.

The group’s net debt rose six-fold to $159 million at the end of 2025. The increase reflected major investment in the WCP A upgrade at a time when weaker output and lower shipments reduced cash generation.

Earnings before interest, taxes, depreciation, and amortisation fell 63% on the year to $58 million. The decline shows how quickly operational disruption can affect earnings when market conditions are already weak.

Market oversupply also weighed on ilmenite and zircon prices despite steady underlying demand. This left Kenmare exposed to both lower sales volumes and weaker pricing across key mineral sands products.

Licence Renewal and 2026 Recovery Shape Moma Outlook

The renewal of the Moma Implementation Agreement remains a major strategic issue. The agreement, which covers Kenmare’s mineral processing and export activities with Mozambique’s government, expired in 2024.

Kenmare applied to restart the agreement in 2022, and negotiations are still ongoing. The company said talks in mid-February made constructive progress, but final terms remain important for long-term valuation and investor confidence.

There are signs of operational recovery in early 2026. By the end of the first quarter, WCP A was regularly operating at its nameplate ore feed processing capacity of 3,500 t/hr, although some production issues continued.

Shipments are tracking in line with the run-rate needed to meet 2026 guidance. Kenmare has also drawn down finished stockpiles to manage capital, suggesting the company is prioritising liquidity while it stabilises production at Kenmare Moma Titanium Minerals Mine.

The Metalnomist Commentary

Kenmare’s workforce cut shows that mineral sands producers are under pressure from both price weakness and project execution risk. Moma’s recovery will depend on stable WCP A performance, stronger titanium feedstock pricing, and a clearer licence framework in Mozambique.

Argentina glacier law reform advances as Milei targets copper mining growth

Argentina senate

Argentina glacier law reform cleared the Senate in a narrow vote. The bill passed 40–31, above the approval threshold. Argentina glacier law reform now moves to the Chamber of Deputies.

The reform would let provinces classify which glaciers protect water resources. Meanwhile, it would label other ice bodies as “non-functional” for protection. As a result, mining could expand into areas previously off-limits.

Argentina glacier law reform marks the first text change since 2010. The government argues the current framework creates legal uncertainty for investors. Therefore, officials frame the reform as a pro-investment reset for resource development.

What the reform changes for mining permits and copper projects

Argentina glacier law reform shifts decision power toward provincial governments. Provinces could add or remove glaciers from the protected inventory using technical criteria. Meanwhile, the national institute would still maintain the core glacier inventory function.

The biggest commercial impact sits in copper. Several copper resources sit inside current glacier perimeters. Therefore, the reform could unlock exploration permits and feasibility work that stalled under the 2010 framework.

Mining provinces backed the bill strongly during the Senate debate. However, several other provinces opposed the reform. As a result, the Deputies vote could stay tight and highly politicised.

Why water security now sits at the center of copper investment risk

Water risk now defines Argentina’s mining debate. Meltwater supports river basins, irrigation, and long-term supply resilience. Therefore, critics argue Argentina glacier law reform threatens a strategic resource.

Environmental groups and activists also amplified pressure around the vote. Protests already spread across dozens of cities earlier this year. Meanwhile, lawmakers warned the reform may trigger a new wave of demonstrations.

Investors must treat social licence as a project input. However, miners can reduce conflict through transparent hydrology studies and basin-level monitoring. As a result, the strongest projects will pair permits with credible water stewardship.

The Metalnomist Commentary

Argentina glacier law reform could accelerate copper pipelines, but it also raises permitting volatility. The winners will de-risk water early and keep communities inside the data loop. Meanwhile, tight votes signal that policy risk will stay priced into Argentina deals.

QMB Nickel Licence Review Signals Tougher Indonesia Nickel Oversight

QMB Nickel Indonesia

QMB nickel licence risk is rising after a landslide damaged a tailings facility at Indonesia Morowali Industrial Park. The Indonesian government is reviewing QMB New Energy Materials’ environmental permit, raising new uncertainty around nickel supply from one of the world’s most important battery materials hubs.

The review follows a landslide at IMIP in Sulawesi on 18 February that damaged heavy equipment and reportedly buried an operator. A final decision has not been made, but the case shows that Jakarta is applying stronger scrutiny to environmental and safety performance across the nickel industry.

QMB nickel licence pressure matters because the company has 150,000 t/yr of nickel capacity in mixed hydroxide precipitate. MHP is a key intermediate for battery supply chains, and any production disruption in Indonesia can quickly affect buyers across China, Korea, Japan, and the global electric vehicle sector.

Tailings Risk Adds Pressure to Indonesia’s MHP Supply Chain

QMB’s operations have not been fully suspended, but output has softened as site conditions continue to evolve. The only clearly unaffected portion appears to be QMB’s ESG-linked joint project with Merdeka Battery Materials, which is designed for around 40,000 t/yr and uses independent tailings infrastructure.

The incident is significant because QMB has already faced tailings-related disruption. A landslide at its tailings dam in March 2025 forced a 45-day shutdown of MHP production. The company restarted operations in May and returned to designed capacity in July.

This repeated disruption highlights a wider risk in Indonesia’s fast-growing nickel sector. Rapid capacity expansion has created major supply growth, but it has also increased pressure on waste management, tailings systems, environmental controls, and operating discipline. For battery makers, the issue is not only nickel volume, but also the reliability and ESG quality of that volume.

RKAB Quotas Tighten the Nickel Operating Environment

Indonesia is also tightening nickel supply through its RKAB production quota system. Government-approved ore quotas for 2026 are expected at around 260mn-270mn t, far below the roughly 379mn t mined in 2025. That signals a structural reduction in ore availability and a more controlled operating environment.

RKAB approvals are increasingly tied to ESG performance, which raises compliance risk for miners and processors. Companies with stronger environmental systems may gain more predictable access to ore and permits, while weaker operators could face delays, output cuts, or licence reviews.

The QMB nickel licence review therefore fits a broader policy shift. Jakarta appears to be reducing grey areas in mining regulation and linking production rights more directly to safety, environmental compliance, and operational accountability. This could support a more sustainable nickel sector, but it may also create near-term supply uncertainty.

The Metalnomist Commentary

Indonesia’s nickel market is moving from aggressive expansion toward stricter control. The winners will be producers that can prove safe tailings management, stable operations, and ESG compliance while still delivering battery-grade nickel at scale.

Loma Larga copper and gold project hit by permit revocation in Ecuador

Loma Larga Cu

Ecuador’s decision to revoke the environmental license for the Loma Larga copper and gold project has thrown a flagship Andean mine into uncertainty. The Loma Larga copper and gold project, controlled by Canada’s Dundee Precious Metals, was classified as strategic by the government but now faces a full permitting reset. As a result, investors in copper and gold are reassessing political and regulatory risk in Ecuador just as the country seeks to grow its mining sector.

Water concerns and local politics stall a strategic mine

The core dispute around the Loma Larga copper and gold project centres on water protection in Azuay province. Local authorities in Cuenca and the Azuay prefecture have published studies warning that underground mining could threaten key water sources. Consequently, the newly merged environment and energy ministry used these findings to justify revoking the project’s environmental permit.

Dundee insists that the Loma Larga copper and gold project complies with national environmental standards and includes robust mitigation measures. However, local opposition has been organised for years, reflecting broader social resistance to high-altitude mining in sensitive watersheds. This clash between national development priorities and regional concerns now risks becoming a test case for how Ecuador balances resource extraction with environmental and social safeguards.

Investor confidence and Ecuador’s copper growth ambitions at risk

The permit revocation raises questions about the stability of Ecuador’s mining policy and its ability to attract long-term capital. Mining industry leaders warn that cancelling the license for the Loma Larga copper and gold project may set a damaging precedent for other large deposits. Investors already face geological, infrastructure and price risks; added regulatory reversals may push some to favour neighbouring jurisdictions such as Peru or Chile.

Meanwhile, Ecuador’s copper concentrate exports continue to grow, underscoring the country’s ambition to scale up production. Yet without clarity over permitting and community consent processes, future projects could be delayed or downsized. For copper and gold supply chains, the episode highlights how local governance and social licence can disrupt even “strategic” assets in emerging mining regions.

The Metalnomist Commentary

The Loma Larga decision is a sharp reminder that environmental legitimacy is now as critical as ore grades and capex in mine development. If Ecuador wants to unlock its copper and gold potential, it must establish predictable, transparent rules that reconcile local water concerns with national growth goals. Otherwise, high-quality deposits may remain stranded, and capital for critical minerals will flow to more predictable jurisdictions.

Appian Omitiomire Copper Project Deal Adds Near-Term Namibia Supply Option

Appian Capital Advisory

Appian Omitiomire copper project acquisition gives the UK-based mining investment firm a near-term African copper development asset at a time when new mine supply remains difficult to bring forward. Appian Capital Advisory has acquired a 95% equity interest in Namibia’s Omitiomire project, also known as Omico Copper.

Appian Omitiomire copper project development could require more than $400mn of capital. The asset contains around 520,000t of copper in mineable inventory and could produce about 30,000 t/yr over an estimated 15-year mine life.

Appian Omitiomire copper project investment comes as copper prices trade near record levels. Tight concentrate availability, falling grades at mature mines, slow permitting and demand from electrification, grids and data centres continue to support the long-term copper case.

The project is located around 140km northeast of Windhoek. Its mining licence is valid until 2036, with an option to renew.

Omitiomire Adds Mid-Scale Copper Growth in Namibia

Omitiomire has a defined mineral resource of 123mn t grading 0.51% copper. The feasibility study supports a mineable inventory of 102mn t at the same grade.

This gives Appian a defined development platform rather than an early-stage exploration concept. In a market short of fast-moving copper projects, a mid-scale asset with a clear mine life can still provide meaningful incremental supply.

Namibia also offers strategic relevance. The country has growing importance in African mining investment, and Appian already has operating exposure through its Rosh Pinah zinc mine.

That existing footprint matters. Local execution, stakeholder engagement, regulatory knowledge and regional operating relationships can reduce development risk for Omitiomire.

The acquisition also strengthens Appian’s African base metals portfolio. Copper, zinc and other energy-transition metals are becoming increasingly important as investors seek exposure to materials tied to electrification and industrial infrastructure.

Processing Route Will Shape Market Impact

Appian’s technical due diligence identified opportunities to improve project value, including a possible shift from leach-based processing to flotation. That decision will be strategically important.

A leach-based flowsheet would expose the project to sulphuric acid availability and pricing. Acid has become a more sensitive cost and supply variable for copper operations using solvent extraction-electrowinning.

A flotation route would produce copper concentrate for smelting. This would link Omitiomire more directly to the global concentrate market, where treatment charges remain under pressure because mine supply is tight and smelting capacity remains competitive.

Appian has already started discussions with potential partners for future offtake. Future material could be placed with a smelter, trading group or strategic industrial buyer.

That flexibility matters because offtake structure can influence financing, project economics and customer alignment. In today’s copper market, securing a route to market is almost as important as developing the mine itself.

The deal also highlights the growing role of specialist mining funds. Major miners remain focused on tier-one copper projects and brownfield expansions, leaving private capital to advance smaller assets that can still add useful supply.

Appian has relevant experience. It previously developed the Serrote copper-gold project in Brazil through Mineracao Vale Verde before selling the asset last year.

The Metalnomist Commentary

Appian’s Omitiomire deal shows why mid-scale copper projects are becoming more valuable in a constrained supply market. The key decision will be processing strategy, because flotation could turn the asset into a concentrate supplier just as smelters compete harder for feed.

Argentina Glacier-Protection Reform Opens New Path for Copper Mining

Argentina glacier

Argentina glacier-protection reform has cleared the lower house, creating a major legal shift for the country’s copper industry. The reform allows provinces to decide which glaciers are functionally important to water resources and which areas may be opened to mining.

The approval followed senate backing on 27 February and passed the lower house late on 8 April by 137 votes to 111. President Javier Milei strongly supported the bill, making official promulgation likely.

Argentina glacier-protection reform could unlock copper resources located along the Andes, where many advanced projects overlap with glaciated areas. Supporters argue the change will reduce legal uncertainty and allow provinces to regulate their own natural resources.

Copper Projects Gain New Resource Expansion Potential

Argentina’s copper industry has remained underdeveloped despite a large resource base. The country holds 116mn t of copper resources, but exported only $4bn of the metal last year, far below Chile’s $50bn in copper sales.

The reform could materially change that outlook. Argentina’s 20 most advanced copper projects represent a combined $21.9bn in investment and may now be able to expand resource bases inside previously restricted glacier perimeters.

The mining secretary has forecast that Argentina could produce more than 1.5mn t/yr of copper by 2035, equal to 6.1% of global output. That target now looks more plausible if legal access improves and the government strengthens its large-investment incentive regime.

Argentina glacier-protection reform therefore comes at a critical moment for copper markets. Global demand from grids, electrification, renewable energy and industrial infrastructure needs large new projects, and Argentina is one of the few jurisdictions with major undeveloped copper potential.

Water Security Backlash Raises Political Risk

The reform has triggered strong opposition from environmental groups, lawmakers and parts of the public. Critics argue that easing glacier protections could threaten Argentina’s water security, especially because glacier meltwater supports rivers and agricultural systems.

Greenpeace activists protested outside the lower house in Buenos Aires and warned that the reform could open the way to damaging much of Argentina’s glacial environment. Opponents say drinking water reserves should not be exposed to mining risk.

Supporters of the reform insist that provinces will not permit mining on glaciers that are vital to water resources. However, implementation will depend on how provinces define “functional” and “non-functional” glaciers in practice.

This creates a new layer of project risk. Copper developers may gain legal opportunity, but they will still need political acceptance, environmental credibility and clear provincial rules to move projects into construction.

The Metalnomist Commentary

Argentina glacier-protection reform could become one of the most important copper policy changes in Latin America. The opportunity is large, but the social licence risk is equally serious if water security concerns are not managed with transparency and science.

EGA posts loss on Guinea write-down as feedstock strategy shifts

Guinea Alumina

EGA posts loss on Guinea write-down after the expropriation of its GAC subsidiary. The EGA posts loss on Guinea write-down despite higher realised aluminium prices and strong value-added sales. However, the EGA posts loss on Guinea write-down also masks operational tweaks to secure alumina and bauxite.

What drove the headline loss

EGA reported Dh3.82bn in EBITDA on Dh15.08bn revenue, up 7.86pc. Before adjustments, net profit reached Dh1.63bn. However, the GAC expropriation pushed the company to a Dh890mn net loss. Guinea suspended GAC shipments in October and revoked the mining licence in May. Authorities reassigned the licence in August to state-owned Nimba Mining. As a result, EGA faced higher bauxite procurement costs and refinery inefficiencies. The company also relied more on third-party alumina.

Operations, output, and pricing signals

EGA produced no bauxite in the first half, versus 7.19mn t a year earlier. Alumina output at Al Taweelah fell 6.56pc to 1.14mn t. Meanwhile, EGA finished a debottlenecking project adding up to 50,000 t/yr of alumina capacity. Primary aluminium output was 1.34mn t, broadly flat year on year. Cast metal production rose 2.92pc to 1.41mn t, with sales up 4.58pc to 1.37mn t. Value-added products increased to 84pc of sales from 82pc. LME aluminium averaged $2,538/t in the period, up from $2,303/t.

The Metalnomist Commentary

The Guinea shock exposed EGA’s feedstock concentration risk but also accelerated diversification. If alternative bauxite and alumina offtakes bed in while Al Taweelah’s debottlenecking delivers, margin drag should ease. Execution now hinges on supply optionality, residue management, and stable energy logistics.

Hudbay Peru copper mine faces temporary shutdown amid social unrest

Hudbay Peru copper mine

Hudbay Peru copper mine operations have been temporarily disrupted by nationwide unrest and local protests in the southern mining corridor. The Hudbay Peru copper mine suspended milling at Constancia after road blockades and demonstrations escalated into security risks. As a result, the company has demobilised non-essential staff while using the shutdown to advance planned maintenance work.

Protests disrupt Peru’s southern mining corridor

Peru’s informal miners have intensified protests over stricter permit rules, repeatedly blocking strategic transport routes. These routes are vital for large producers in the southern mining corridor, including the Hudbay Peru copper mine at Constancia. Meanwhile, riots in Lima and demonstrations near the site heightened safety concerns and forced the temporary halt in milling operations.

However, Hudbay is trying to turn the disruption into an operational opportunity. The company plans to use the downtime for preventative maintenance and to pull forward scheduled work originally planned for later in the year. This approach aims to minimise future interruptions once the Hudbay Peru copper mine resumes normal throughput.

Production guidance remains intact despite Constancia halt

Hudbay has stressed that the temporary suspension should not derail its 2025 output targets. The company continues to reaffirm its copper production guidance of 117,000–149,000t for the year, despite the pause at Constancia. As a result, investors and customers are being reassured that the disruption is manageable rather than structural.

Constancia has operated since 2014 and remains one of Peru’s key copper assets. Therefore, any downtime at the Hudbay Peru copper mine is closely watched by global copper markets. Yet the company’s signal that guidance remains unchanged suggests that ore stockpiles, flexible scheduling and maintenance planning are cushioning short-term impacts.

Hudbay is also engaging with government and legal authorities to help resolve the unrest. In the near term, the stability of the southern mining corridor will depend on how quickly authorities can defuse conflict with informal miners. As a result, the risk profile for Peru’s wider copper sector remains elevated, even if Constancia’s immediate production outlook appears secure.

The Metalnomist Commentary

Constancia’s brief halt is another reminder that social licence, not geology, often dictates copper supply risk. If Peru cannot stabilise its permitting and informal mining framework, financing costs for future greenfield projects may rise. For now, Hudbay’s maintained guidance signals resilience, but repeated disruptions could eventually tighten the global copper balance.

Verde Magnesium Listed as EU Strategic Project

Verde Magnesium

CRMA recognition boosts Romania’s plan to revive European magnesium production

EU Backs Verde Magnesium for Local Supply Security

The EU has designated Verde Magnesium’s Romanian project as a strategic initiative under the Critical Raw Materials Act (CRMA). This decision aims to re-establish magnesium production within the EU for the first time in over two decades. Verde Magnesium will build an integrated mining and processing facility in Budureasa, Bihor County.

Currently, the EU imports 97% of its magnesium metal from China, creating significant supply risk. As a result, the EU seeks to diversify sourcing and enhance resilience through domestic production. Verde’s project aligns with this goal and will benefit from fast-tracked permitting and regulatory support.

Production Timeline and Investment Outlook

Verde Magnesium expects to begin commercial operations by the end of 2028. Initial production will range from 15,000 to 20,000 t/yr, increasing to 30,000 t/yr in 2030. By 2036, the facility aims to reach peak output of 90,000 t/yr.

However, earlier targets were delayed due to licensing issues with Romania’s National Agency for Mineral Resources. The company finally secured the mining licence in April, allowing development to move forward. Though CRMA designation does not guarantee EU funding, it may unlock institutional investment.

Strategic Material for EU Industry

Magnesium is vital for alloying in aluminium, automotive, aerospace, and defence applications. Its inclusion on the CRMA’s strategic materials list highlights its industrial importance. Verde CEO Alexandru Rosu said the site will become a low-carbon hub for extraction, processing, and recycling in Europe.

France’s Pechiney operated the EU’s last magnesium facility until Chinese imports forced its closure in 2001. Verde’s return could reduce reliance on volatile global supply chains and restore European production capability.

The Metalnomist Commentary

Verde Magnesium’s CRMA status reflects Europe’s intent to de-risk supply chains and revive critical material independence. With high demand across strategic sectors, restoring EU-based magnesium production is both a geopolitical and industrial imperative.

EGA Signs Ghana Bauxite Development Agreement to Boost Supply

Emirates Global Aluminium

Strategic Partnership to Expand Ghana’s Bauxite Industry

Emirates Global Aluminium (EGA) has signed an agreement with Ghana Integrated Aluminium Development (GIADEC) to explore bauxite-related projects in Ghana. The partnership will assess long-term bauxite offtake potential and collaborate on rail and port infrastructure to raise Ghana’s bauxite production from the current 1.5mn t/yr. Ghana holds over 900mn t of reserves across three known deposits, positioning it as a strategic supplier in the global aluminium value chain.

Diversifying Supply Amid Guinea Dispute

EGA is diversifying its bauxite sourcing following a shipment suspension from its Guinea Alumina subsidiary in October. The suspension was triggered by delays in EGA’s alumina refinery plans, leading to an escalating dispute with the Guinean government. In recent months, Guinea has moved to revoke EGA’s mining licence and rescinded over 50 licences for various minerals. EGA’s chief executive, Abdulnasser Bin Kalban, confirmed that doubling bauxite output remains a key objective, with Ghana now a primary focus in its global expansion strategy.

The Metalnomist Commentary

This agreement strengthens Ghana’s position in the aluminium supply chain while offering EGA a critical hedge against geopolitical risk in Guinea. Successful execution could help stabilize EGA’s raw material supply and drive investment in Ghana’s infrastructure, boosting both export capacity and economic growth.

Al Taweelah alumina refinery expansion boosts output as EGA retools bauxite supply

EGA

EGA’s Al Taweelah alumina refinery completed a debottlenecking project that lifts capacity by 50,000 t/yr. The Al Taweelah alumina refinery now has more headroom within its 2mn t/yr nameplate. The Al Taweelah alumina refinery upgrade centers on reliability and future growth.

Reliability upgrade: third ball mill and outage risk reduction

EGA installed a third ball mill to ease bottlenecks and reduce unplanned outages. The new mill increases grinding flexibility and operating redundancy. As a result, the refinery can sustain higher throughput and pursue further expansions. Management framed the project as a low-risk, quick-impact step.

Supply chain shift: beyond Guinea toward Ghana options

EGA is diversifying bauxite supply after Guinea revoked and reassigned its mining licence. The company signed an agreement with Ghana Integrated Aluminium Development to explore bauxite projects. Ghana holds over 900mn t of reserves across three deposits. Therefore, EGA aims to build a resilient, multi-source feedstock strategy that supports refinery stability.

The Metalnomist Commentary

The incremental 50,000 t/yr is modest but strategic, improving uptime and optionality. Watch how Ghana sourcing matures and whether EGA secures additional long-term bauxite offtake to de-risk Al Taweelah’s feedstock.

Argentina copper mine investment accelerates under Rigi incentive framework

Argentina copper mine

Argentina copper mine investment is entering a new phase under the Rigi incentive framework. The approval of McEwen Copper’s $2.7bn Los Azules project signals that Argentina copper mine investment is now central to the Milei government’s economic strategy. As a result, Argentina copper mine investment is being positioned as a key pillar for both fiscal reform and long-term export growth.

Rigi turns Los Azules into a flagship Argentina copper mine investment

The Los Azules project is the first copper mine approved under Argentina’s large-scale investment regime, Rigi. The scheme offers a 25pc tax rate instead of 35pc, 30 years of legal stability and exemption from import duties on capital goods. These incentives are designed to de-risk Argentina copper mine investment amid currency volatility and political uncertainty. Construction at Los Azules could begin as early as 2026, subject to permitting approvals. The mine is expected to produce about 175,000 t/yr of copper, placing it among the country’s most significant future producers. This scale matters for Argentina’s balance of payments, because copper exports can provide stable hard-currency revenues.

Copper anchors Argentina’s wider energy and mining investment push

The Los Azules approval is part of a broader Rigi pipeline that already totals $15.7bn in committed projects. The portfolio spans two solar plants, two lithium mines, an oil pipeline, an LNG facility and a steel mill. Together, these projects illustrate how copper, lithium and energy infrastructure are being bundled into a single strategic investment narrative. The government is targeting at least $50bn in energy investment and another $50bn in mining by 2027. That timeline aligns with president Javier Milei’s current term and his wider macroeconomic adjustment agenda. At the same time, Argentina is courting external financial support, including a potential $20bn currency swap backed by the US government. Stable capital inflows are critical to sustain Rigi and reassure foreign mining investors.

The Metalnomist Commentary

Los Azules shows how targeted tax stability and customs relief can unlock large-scale copper capex even in a risky macro environment. The challenge will be execution: permitting, infrastructure delivery and social licence will determine whether this project hits its 2026–27 window. For the global copper market, Argentina’s success or delay at Los Azules will shape future supply expectations in the second half of the decade.
