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.

Spain Critical Raw Materials Plan Targets Mining Supply Chain Revival

Spain Mining

Spain critical raw materials policy is moving into a more active phase as the government prepares to invest €414 million to strengthen domestic mining and raw material supply. The funding will support recycling, mineral exploration, abandoned mine restoration, and workforce training across the Spanish mining sector.

The plan reflects Europe’s wider push to reduce dependence on imported critical minerals. Spain already holds an important position in the EU mining landscape. It ranks as the bloc’s second-largest copper producer and third-largest tungsten producer, giving the country a stronger base than many European peers.

Spain critical raw materials investment also comes as the EU accelerates project selection under the Critical Raw Materials Act. The European Commission has selected seven strategic mining and raw material projects in Spain, placing the country just behind Germany and France in the European project pipeline.

National Exploration Program Signals a Return to Resource Strategy

The most important part of the plan is Spain’s first National Mining Exploration Program in 50 years. The government plans to allocate €182 million to the program, marking a major shift from passive resource ownership to active resource development.

Exploration is critical because Europe’s raw material strategy cannot rely only on known deposits. Copper, tungsten, lithium, rare earths, and other strategic minerals require long development timelines. Without fresh exploration, permitting reform, and financing support, Europe’s supply ambitions will remain exposed to overseas sources.

Spain’s geological position gives the program clear industrial relevance. Copper supports power grids, electrification, renewable energy systems, and industrial manufacturing. Tungsten remains important for hard metals, defense applications, aerospace tooling, and high-performance manufacturing. As a result, the Spanish mining sector could become more strategically important to Europe’s energy transition and industrial security.

Financing Risk Remains the Main Barrier for Spanish Mining Projects

Spain critical raw materials funding addresses a long-standing complaint from mining companies. Industry players have asked for clearer financial and regulatory support because many emerging projects remain stalled despite strong policy interest.

The core problem is risk. Mining projects require large upfront capital, long permitting processes, and uncertain development timelines. Banks and investors often hesitate to provide credit lines, especially for early-stage projects that lack proven production economics.

The new funding can help reduce that gap, but it will not solve every obstacle. Spain must still convert policy support into bankable projects, faster approvals, skilled labor, and reliable infrastructure. If the government succeeds, the Spanish mining sector could become a stronger pillar of Europe’s critical raw materials strategy.

The Metalnomist Commentary

Spain’s plan is strategically important because it links exploration, recycling, and mine restoration into one raw materials agenda. However, the decisive test will be whether public funding can unlock private capital for projects that banks still view as too risky.

Brazil Mineral Exports Rise as Imports Climb on Fertilizer Feedstock Demand

Brazil Mining

Brazil mineral exports increased in the first quarter of 2026, while imports rose more sharply as the country continued to rely on overseas supply for fertilizer-related minerals. National mining institute Ibram reported that mineral exports rose by nearly 1% from a year earlier, while imports increased by 15%.

Brazil mineral exports reached around 87.9mn t in the quarter, with China remaining the main destination. Iron ore accounted for nearly 54% of total shipments, reinforcing its central role in Brazil’s mining trade balance.

Brazil mineral exports continued to support a large sectoral surplus. The mineral trade surplus reached around $9.3bn in the first quarter, up 20% from the same period in 2025, supported by exports of iron ore, gold and copper.

Iron Ore, Gold and Copper Anchor Brazil’s Mining Surplus

Iron ore remained Brazil’s dominant mineral export in the first quarter. This reflects the country’s established role as one of the world’s key suppliers to steelmaking markets, especially China.

Gold and copper also contributed to export value. These metals are strategically important because gold supports financial and industrial demand, while copper is increasingly tied to grids, electrification, construction and manufacturing.

The rise in the mining trade surplus shows that Brazil’s mineral sector remains a strong foreign-exchange earner. Even modest export volume growth can generate a larger surplus when high-value commodities and stronger pricing conditions support trade values.

China’s role remains especially important. Brazilian iron ore exports depend heavily on Chinese steel demand, infrastructure activity and industrial production. Any slowdown in China can therefore affect Brazil’s mining revenue outlook.

Imports Highlight Fertilizer and Industrial Supply Dependence

Brazil imported 10mn t of mineral products in the first quarter. The US was the largest supplier, accounting for 19% of mineral imports, while Colombia and Canada each supplied about 13%.

Potassium, coal and sulphur led import flows. These materials are important for fertilizer supply and industrial activity, showing that Brazil’s mineral strength does not remove its dependence on imported inputs.

Potassium is especially important for Brazil’s agricultural sector. The country is a major global food producer, but fertilizer supply remains exposed to international trade flows and geopolitical risk.

Sulphur imports also matter because sulphur is used to produce sulphuric acid, a critical input for fertilizers, chemical processing and some mining operations. Coal imports continue to support industrial and energy-related demand.

Ibram projects mining sector investment to rise by 12.5% by 2030, reaching $76.9bn. Critical minerals could account for almost 28% of that total, or $21.3bn.

This investment outlook points to a broader shift in Brazil’s mining strategy. Iron ore will remain the export backbone, but copper, nickel, lithium, rare earths, graphite and other critical minerals could gain strategic importance as global supply chains diversify.

The Metalnomist Commentary

Brazil’s first-quarter trade data show a mining sector that remains strong in exports but still dependent on imported fertilizer and industrial inputs. The next opportunity lies in converting critical minerals investment into higher-value production beyond the country’s traditional iron ore base.

Ecuador Increases Power Tariffs for Copper Mines Amid Energy Crisis

Ecuacorriente S.A

In a move to address Ecuador's ongoing energy crisis, the country’s electricity regulatory agency, Arconel, has raised power tariffs for large-scale industries, including the copper mining sector. This change, which took effect on October 30, has significant implications for major mines in the country, notably Mirador, operated by China's Ecsa-Ecuacorriente, and Fruta del Norte, operated by Canadian company Lundin. The revised tariffs will impact electricity consumption during peak hours, further exacerbating the financial pressure on mining operations already grappling with soaring costs.

Key Changes to Power Tariffs

The new electricity tariffs target industries that consume the most power, with particular emphasis on mining operations. The most notable increases are:

• Peak Hours (6-10 pm): Increased from 8.10¢/kWh to 9.86¢/kWh.
• Daytime (8 am-6 pm): Raised from 6.8¢/kWh to 8.5¢/kWh.
• Off-Peak (10 pm-8 am): Increased from 5.4¢/kWh to 7.5¢/kWh.

These price hikes will affect two major mines in Ecuador: the Mirador copper mine, which is one of the country’s largest, and the Fruta del Norte gold mine. The tariff increases are a direct response to the national energy shortage caused by a harsh drought, which has significantly reduced the output from Ecuador’s primary hydroelectric plants.

Impact of Ecuador's Energy Crisis on Mining

Ecuador is currently facing a severe energy crisis, exacerbated by a lack of rainfall, which has hindered the operation of hydroelectric plants. As a result, the country has had to rely heavily on thermoelectric power generation, leading to a 77% increase in thermoelectric fuel consumption in the third quarter of 2024 compared to the same period in 2023, according to Petroecuador, the state-owned oil and energy company.

Despite the increase in energy costs, the Ecuadorian mining chamber, which represents companies like Ecsa-Ecuacorriente and Lundin, has acknowledged that the tariff hike is necessary due to the energy crisis. The increased electricity tariffs are expected to affect the operational costs of these mines, making them less competitive in the global market.

Ecuador's Mining Exports and the Role of Copper

Ecuador's mining sector plays a crucial role in the country’s economy. In the first half of 2024, Ecuador exported $688.8 million in copper concentrate, accounting for 42% of the country's total income from metal exports, which amounted to $1.6 billion. Copper export revenues saw a 12% increase from the previous year, highlighting the growing importance of copper as a key driver of the national economy.

The rise in power tariffs, however, may put the profitability of copper mining operations under strain, particularly for Mirador, one of Ecuador’s largest copper producers. While the mining chamber has voiced support for the tariff increase, it remains to be seen how these changes will affect long-term investment and growth in Ecuador's mining sector.

South Africa to Criminalise Illegal Mining While Supporting Artisanal Miners

S Africa Illegal Mining

New Legal Framework to Tackle Illegal Mining

South Africa will criminalise illegal mining for the first time, marking a significant policy shift to combat long-standing challenges in its mining sector. Deputy minerals and petroleum resources minister Phumzile Mgcina announced the change at the London Indaba conference, emphasizing that current laws do not classify illegal mining as a crime. The new legal framework will allow enforcement officers to enter illegal sites and make arrests immediately, strengthening the state’s ability to curb the activity.

Illegal mining, often driven by depleted industrial mines, involves an estimated 30,000 miners known as “zama zama.” These miners target gold, platinum group metals (PGMs), chromium, and manganese. The Global Initiative Against Transnational Organized Crime estimates that the country loses about 10pc of annual chrome output to illegal operations, empowering criminal networks and eroding formal industry revenues.

Artisanal Mining Licences as a Pathway to Legitimacy

While introducing strict measures against illegal operations, the government has created artisanal mining permits under its critical minerals and metals strategy. This initiative differentiates artisanal mining from criminal activities, aiming to integrate small-scale miners into the formal economy.

Permits will address long-standing bottlenecks such as delays in processing applications and poor transparency. By granting artisanal miners legal recognition, the government seeks to provide support systems, ensure compliance with environmental and safety standards, and reduce the appeal of illegal mining. This dual strategy responds to international criticism following the government’s earlier crackdown, which cut off food and water to hundreds of trapped miners, leading to deaths.

The Metalnomist Commentary

South Africa’s decision to criminalise illegal mining while formalising artisanal operations represents a balancing act between security and inclusion. This approach could reduce the influence of criminal groups, but its success will depend on efficient permit administration and robust enforcement capacity. The international mining community will closely monitor how these reforms reshape the sector’s stability and sustainability.

US Venezuelan Critical Mineral Licences Open Sanctions Path for Mining Investment

US, Venezuelan

US Venezuelan critical mineral licences have created a new legal route for mineral investment and operations in Venezuela under strict sanctions guidelines. The US Treasury Department issued new and amended general licences on 27 March, allowing limited mineral-related activities and contingent investment agreements.

The licences permit the supply of certain items and services for minerals operations. They also allow negotiations and contingent contracts for investment in Venezuela’s minerals sector, including certain contracts with state-owned miner Minerven if governed under US law.

US Venezuelan critical mineral licences reflect Washington’s attempt to reconnect parts of Venezuela’s resource sector with US-linked investment. However, the opportunity remains complicated by illegal mining, weak infrastructure, political risk and security concerns in key mineral regions.

Venezuela’s Mineral Potential Comes With High Execution Risk

Venezuela is believed to hold strategic resources including copper, nickel, columbite-tantalite and uranium, although available public data do not provide clear reserve volumes. The Orinoco Mining Arc in southern Bolívar state is one of the country’s richest mining regions, with deposits of coltan, bauxite, gold and other metals.

The Orinoco Mining Arc has been designated as a strategic development zone, but the region remains difficult for formal investors. Illegal mining, mineral smuggling, money laundering and the presence of non-government armed groups create serious operational and compliance risks.

Some public-private partnerships already operate in coltan-rich areas, while Venezuela’s armed forces also maintain mining activity through Camimpeg. These structures add further complexity for any foreign company evaluating due diligence, security and legal exposure.

Sanctions Relief Could Support Critical Mineral Strategy

US Venezuelan critical mineral licences come as the US seeks more diversified sources of technology and defense-related minerals. Venezuela’s potential resource base could attract interest if companies can manage sanctions compliance, contract structure, security and infrastructure constraints.

The new licences also follow Venezuela’s effort to open its mining sector to more investment. The national assembly passed a new mining law in an initial vote on 9 March, signalling a policy push to revive resource development.

Still, economic instability remains a major obstacle. Venezuela continues to face currency weakness, very high inflation and years of underinvestment across industrial infrastructure. These conditions mean sanctions relief alone will not quickly convert mineral potential into reliable supply.

The Metalnomist Commentary

The US Venezuelan critical mineral licences are strategically important, but they do not remove the hard risks on the ground. Venezuela may hold valuable minerals, yet the real test will be whether legal access, security, infrastructure and transparent sourcing can be aligned.

Burundi Mining Suspension Raises 3T Conflict Minerals Supply Risk

Burundi mining

Burundi mining suspension measures have halted nearly all mining operations in the country, leaving only Sotrevo Mining and Sonalek Mining allowed to continue operating. The move creates new uncertainty for tantalum, tungsten and tin supply from one of Africa’s smaller but strategically important 3T mineral producers.

Burundi mining suspension measures require mining companies and co-operatives to apply for new operating permits before restarting. The government said operating approvals and the state’s share of production will be decided case by case.

Burundi mining suspension rules also introduce the threat of severe sanctions for companies that ignore the new requirements. This signals a stronger state push to control mineral production, permitting and revenue sharing.

The decision matters because Burundi supplies 3T concentrates at a time when buyers are already sensitive to conflict minerals risk, origin documentation and supply disruption across central and eastern Africa.

Permit Reset Raises Supply Risk for 3T Minerals

The suspension affects all mining sites except those operated by Sotrevo Mining and Sonalek Mining. Sotrevo produces tantalum, tungsten and tin, while Sonalek Mining also remains exempt from the suspension.

The ministry’s decision effectively resets the operating framework for much of Burundi’s mining sector. Producers that previously operated under existing arrangements must now seek new approval before they can resume work.

This creates immediate supply-chain uncertainty. Buyers may face delays in shipments, reduced availability and additional documentation requirements while companies wait for permit decisions.

Burundi produced 421t of 3T concentrates in 2024, according to industry supply-chain data referenced in the source material. That volume is not large compared with global mined supply, but it matters for buyers seeking diversified and traceable African material.

Tantalum is critical for capacitors used in electronics, aerospace, defence systems and medical devices. Tungsten supports hard metals, cutting tools, defence applications and industrial machinery. Tin is essential for solder, electronics assembly and coatings.

The suspension therefore affects more than local mining companies. It reaches downstream electronics, tooling, defence and manufacturing supply chains that depend on stable 3T material flows.

Conflict Mineral Markets Face New Compliance Pressure

Burundi has gained importance because conflict and instability in other major 3T-producing countries have increased demand for its material. Buyers looking to diversify regional supply have turned to Burundian concentrates as an alternative source.

The new suspension complicates that trend. Even if the government aims to strengthen oversight, the immediate effect is to reduce clarity for exporters, traders and downstream consumers.

The case-by-case permit process could also reshape the country’s mining structure. Companies with stronger compliance systems, clearer production records and better state relationships may be better positioned to restart.

For responsible sourcing programmes, the policy shift adds another layer of due diligence. Buyers will need to confirm not only mine origin and chain of custody, but also whether suppliers hold valid new operating permits.

The state’s share of production will also be decided individually. This could change project economics and create different cost structures across operators.

Burundi’s decision reflects a wider trend in critical minerals. Resource-holding governments increasingly want more control over production, exports and domestic value capture.

For 3T markets, the timing is sensitive. Supply chains already face scrutiny under conflict minerals rules, while manufacturers need stable feedstock for electronics, aerospace, defence and industrial applications.

If the suspension is resolved quickly, the market impact may stay limited. If permitting delays continue, Burundi’s role as a flexible alternative source of 3T concentrates could weaken.

The Metalnomist Commentary

Burundi’s mining suspension shows how even smaller suppliers can affect strategic mineral confidence. In 3T markets, regulatory clarity and traceability are now as important as mined volume itself.

Sherritt Moa Nickel-Cobalt Suspension Deepens Cuba Supply Chain Risk

Sherritt

Sherritt Moa nickel-cobalt suspension has moved from sanctions review to direct operational action after the Canadian miner and refiner halted its participation in activities tied to the Moa joint venture in Cuba. The decision follows new US sanctions authority that could target entities operating in Cuba’s metals and mining sector.

Sherritt Moa nickel-cobalt suspension is significant because the Moa joint venture links Cuban mine and intermediate processing operations with Sherritt’s refining capacity in Alberta. Ore is mined and processed in Cuba into mixed sulfide precipitate containing nickel and cobalt, then shipped to Canada for refining.

Sherritt Moa nickel-cobalt suspension adds another layer of disruption to an already fragile supply route. The company had temporarily suspended mining operations at Moa in February because of fuel supply problems in Cuba.

Although Sherritt was not directly named in the new US sanctions, the company said the executive order is expected to create conditions that make operating in Cuba more difficult. That risk was enough for Sherritt to suspend direct participation in Moa-related activities.

Sanctions Risk Hits a Cross-Border Nickel and Cobalt Chain

The new US executive order expands sanctions authority under the International Emergency Economic Powers Act. It allows Washington to sanction entities operating in Cuba’s metals and mining sector, along with several other industries.

That broad language creates uncertainty for companies with Cuban exposure. Even without direct designation, counterparties may become more cautious around shipping, banking, insurance, payments, logistics and commercial contracts.

For Sherritt, the issue is not only legal exposure. It is the practical ability to keep a cross-border supply chain functioning when sanctions risk rises around the Cuban mining sector.

The Moa joint venture is co-owned by Sherritt and the General Nickel Company of Cuba. Its structure depends on Cuban ore mining, local MSP production and shipment to Canada for refining.

Mixed sulfide precipitate is a critical intermediate product because it carries both nickel and cobalt units into downstream refining. Any interruption in MSP flows can affect feed availability at the refinery level.

Nickel and cobalt remain important to batteries, stainless steel, superalloys, industrial chemicals and advanced manufacturing. That makes Moa strategically relevant despite its political and logistical complexity.

Alberta Refinery Continues but Feedstock Window Narrows

Sherritt said its Fort Saskatchewan refinery in Alberta has not been affected by the suspension and will continue producing finished nickel and cobalt. Existing feed at the site is expected to last until mid-June.

That timeline is now critical. If Cuban MSP flows do not resume or alternative feedstock is not secured, refinery operations could face greater pressure once inventories are depleted.

The situation shows how refining capacity can still be vulnerable when upstream feedstock depends on a politically exposed jurisdiction. A refinery may remain operational, but its production outlook depends on the continuity of intermediate material supply.

The February fuel-related suspension at Moa already showed that physical operating conditions in Cuba were difficult. The latest sanctions-driven action compounds that problem by adding policy risk to fuel and logistics constraints.

For customers, the key question is whether Sherritt can maintain finished nickel and cobalt output after mid-June. Buyers will also watch for any change in shipment schedules, inventory levels and alternative feed strategies.

For the wider market, Sherritt’s case highlights a broader critical minerals reality. Western supply security cannot be measured only by refining location. It must include mine jurisdiction, intermediate processing, sanctions exposure, energy availability and shipping routes.

The Metalnomist Commentary

Sherritt’s Moa suspension shows that critical minerals supply chains can be disrupted by policy risk even before a company is directly sanctioned. The lesson for nickel and cobalt buyers is clear: feedstock origin and political exposure now matter as much as refining capacity.

Codelco Rio Tinto Partnership Targets Faster Mining Development in Chile

Codelco Rio Tinto Partnership

Codelco Rio Tinto partnership plans could accelerate major mining development in Chile as the state-owned copper and lithium group seeks deeper cooperation with global miners. The preliminary agreement will focus on identifying joint investment opportunities in large-scale mining projects across the country.

Codelco and Rio Tinto will create an executive committee made up of senior officials from both companies. The committee will identify prospective pilot projects, assess major mining opportunities, and oversee implementation where cooperation advances.

The Codelco Rio Tinto partnership reflects a broader strategic shift inside Chile’s mining sector. Codelco wants to accelerate timelines, reduce costs, and improve ESG compliance by sharing technical knowledge with established international mining companies.

Chile Turns to Partnerships to Unlock Copper and Lithium Growth

Chile remains one of the world’s most important copper producers, but project development has become more difficult. Lower ore grades, permitting complexity, water constraints, community expectations, and capital intensity are increasing the pressure on producers.

Codelco’s partnership strategy aims to address those constraints. By working with companies such as Rio Tinto, the Chilean state miner can access technical expertise, operational experience, project discipline, and global capital networks. This could help move exploration and development projects faster.

The agreement also builds on Codelco’s recent cooperation with other major miners. The company partnered with BHP last year to enhance copper exploration in the Antofagasta region. This suggests Codelco may pursue more private-sector alliances as Chile works to protect its long-term copper output.

Rio Tinto Ties Strengthen Chile’s Critical Minerals Platform

Rio Tinto and Codelco have already been strengthening their relationship through work on the Maricunga lithium project and the Nuevo Cobre region. The new agreement broadens that cooperation and positions both companies to explore additional copper and lithium opportunities.

This matters because Chile is central to both traditional mining and the energy transition supply chain. Copper remains essential for power grids, electrification, EVs, renewables, and industrial infrastructure. Lithium remains strategically important for batteries and energy storage.

The Codelco Rio Tinto partnership therefore carries value beyond individual projects. It signals that Chile’s mining future may depend increasingly on structured cooperation between state-owned champions and global mining companies with advanced technical and ESG capabilities.

The Metalnomist Commentary

Codelco’s partnership model shows that Chile understands the limits of going alone in a more complex mining environment. The next competitive advantage will come from faster permitting, stronger technical execution, and alliances that can turn resource potential into reliable supply.

Chile Copper Mining Power Demand to Surge by 2034

Chile Copper

Rising Energy Needs Driven by Processing Shifts

Chile’s copper mining sector will face a sharp rise in power demand over the next decade. According to Cochilco, the state copper commission, the industry will require 32.5TWh of electricity in 2034, up 21% from 26.9TWh in 2024. In contrast, copper production will only expand by 5.6% to reach 5.7mn tonnes in the same period. The mismatch highlights the growing energy intensity of mining operations as ore grades decline.

A higher proportion of copper concentrate production and the increased use of desalinated seawater will drive demand. Cochilco estimates copper concentration will consume 18.7TWh in 2034, or 58% of the sector’s total power. Meanwhile, desalination and pumping water to arid northern mines will account for 5.4TWh, representing 17% of consumption.

Transition to Renewables Amid Rising Costs

Chile’s copper industry has already shifted much of its energy base toward renewables. By 2024, renewables represented 74% of the sector’s electricity use, with contracts steadily renegotiated away from fossil fuels. Cochilco forecasts this share will rise to 78% by 2026. Despite this progress, the overall growth in electricity demand underscores potential cost pressures and supply security challenges for producers.

Copper mining already accounts for one-third of Chile’s total power consumption, and the anticipated rise may stress the country’s grid capacity. Therefore, balancing sustainable energy supply with rising industrial needs will be central to maintaining Chile’s global copper dominance.

The Metalnomist Commentary

Chile’s copper sector is entering an era where energy demand grows faster than metal output. The transition to cleaner power sources is vital, but rising electricity costs and desalination needs will weigh on margins. Global buyers of copper should expect long-term pricing influenced not only by supply-demand balances but also by the escalating energy footprint of mining operations.

Terramin Signs Major EPC Contract with Sinosteel for Tala Hamza Zinc Project

Terramin Australia

Terramin Australia, a South Australia-based mining group, has signed a significant engineering, procurement, and construction (EPC) contract with Sinosteel, a Chinese state-owned mineral and metallurgical firm. This agreement is for the construction of the Tala Hamza zinc project, located in Algeria, marking a major step toward the development of one of the country’s most promising mining ventures.

Key Details of the Tala Hamza Zinc Project

The £336 million EPC contract includes the construction of a 2 million tonnes per year (2mn t/yr) processing plant and an underground mine. Terramin's executive chair, Bruce Sheng, emphasized that the project would play a pivotal role in boosting the Algerian economy as it progresses.

The Zinc and Lead Resources of Tala Hamza

The Tala Hamza deposit is considered rich in both zinc and lead. According to Terramin, the deposit contains a resource of 53 million tonnes at 5.3% zinc and 1.3% lead, with a cut-off grade of 2.5% zinc-equivalent. A definitive feasibility study completed in 2018 estimated that the mine could produce an average of 129,300 tonnes per year of zinc concentrate and 26,000 tonnes per year of lead concentrate over a 21-year mine life.

As part of the project, the construction of the processing plant and mine infrastructure is expected to create numerous job opportunities in Algeria, further enhancing the project's economic importance.

Implications for the Algerian Mining Sector

The Tala Hamza zinc project has the potential to become one of Algeria's flagship mining projects. Not only will it contribute to the country's zinc production capacity, but it will also bolster Algeria's mining sector, attract foreign investment, and provide long-term economic benefits. With the involvement of Sinosteel, a major player in global metallurgy, the project also signals strong international confidence in Algeria’s mining prospects.

Conclusion

The signing of the EPC contract for the Tala Hamza zinc project represents a significant milestone for Terramin Australia and its partners. The project is expected to help meet the growing global demand for zinc and lead while supporting Algeria's economic growth. As construction begins, the focus will now shift to timely execution and the successful development of a high-quality mining operation in the region.

Lundin Mining Sells Neves-Corvo and Zinkgruvan Mines to Boliden for $1.52bn

Lundin Mining

Canada-based Lundin Mining announced the sale of its two major European mining operations — Neves-Corvo in Portugal and Zinkgruvan in Sweden — to Swedish Boliden for a total of $1.52 billion. The deal, which is expected to close by mid-2025, will represent Lundin’s complete exit from its operating assets in Europe. The company plans to use the proceeds from this sale to strengthen its balance sheet and fuel its growth strategy in South America.

Key Details of the Deal

The acquisition will significantly boost Boliden’s mining and smelting capacity. Neves-Corvo and Zinkgruvan produced a combined total of 185,000 tonnes of zinc concentrate and 38,000 tonnes of copper concentrate in 2023. With this acquisition, Boliden anticipates a sharp increase in its output, especially in zinc, which is expected to rise to 70% of its zinc smelting capacity (up from 35%). For copper, Boliden forecasts an increase in concentrate production to 40% of its copper smelting capacity, from 30%, based on 2023 figures.

In 2023, Neves-Corvo produced 108,812 tonnes of zinc and 33,823 tonnes of copper, while Zinkgruvan produced 76,349 tonnes of zinc and 4,434 tonnes of copper, both in concentrate. This expansion aligns with Boliden's ongoing efforts to boost its mining capabilities in Europe and provide a stronger foundation for its future operations.

Boliden’s Expanding Operations

Following the completion of the transaction, Boliden will operate a total of seven mining areas and five smelters, further solidifying its position as a key player in the European metals market.

The Neves-Corvo and Zinkgruvan mines come with on-site processing facilities, which will enable Boliden to efficiently manage the mining and refining of these crucial metals.

Lundin’s Strategic Shift

For Lundin Mining, the sale marks a strategic shift toward focusing its operations on high-growth regions, particularly in South America, where the company has substantial mining interests. By exiting Europe, Lundin aims to optimize its portfolio and concentrate resources on projects that offer the highest potential for expansion and value creation.

Conclusion

The $1.52 billion deal between Lundin Mining and Boliden highlights the growing consolidation in the mining sector and underscores the importance of strategic acquisitions to secure long-term growth. For Boliden, the acquisition of Neves-Corvo and Zinkgruvan will enhance its production capacity, positioning the company to meet rising global demand for zinc and copper. Meanwhile, Lundin Mining is set to reorient its focus on South American mining assets, setting the stage for future growth.

Updates Mining Rebate Rules: What You Need to Know

US Mining

The United States has introduced significant updates to its mining rebate rules, affecting companies in the mining and materials processing sectors. The U.S. Treasury Department and the Internal Revenue Service (IRS) released definitive rules on Thursday regarding the Section 45X advanced manufacturing production credit, a part of the Inflation Reduction Act (IRA) of 2022. This credit was designed to foster investment in the U.S. manufacturing of components for wind, solar, and battery systems.

Key Changes to the Mining Rebate Rules

The new regulations bring forth an important adjustment for mining companies, particularly regarding "extraction costs." Previously, under the proposed guidance issued in December, extraction was not considered part of the production costs eligible for the 10% rebate. The rationale was that the extraction process was seen as too far removed from the ultimate production of an eligible component, such as those used in wind and solar energy systems.

However, after considerable feedback from stakeholders, the Treasury Department and IRS revised their stance. The updated rules now allow mining companies to claim the rebate for their extraction costs, provided the raw materials are processed into an eligible component. For example, lithium must be refined into lithium hydroxide, which can then be used directly in the production of batteries.

While the regulators acknowledged the importance of value-added processing activities, such as refining and purifying raw materials, they also clarified that "the action of extraction alone does not produce an eligible component." This decision effectively allows certain mining activities to qualify for the credit, but it is important to note that extraction alone, without subsequent processing, does not meet the eligibility requirements.

Industry Reactions and Future Implications

The updated guidance has generated mixed reactions within the industry. On one hand, groups representing mining companies welcomed the inclusion of extraction in some capacity, recognizing the importance of the sector in the overall supply chain for clean energy technologies. On the other hand, some stakeholders, including the National Mining Association (NMA), expressed disappointment over the narrow scope of the final rules.

Rich Nolan, CEO of the National Mining Association, argued that the decision to limit the rebate to producers who also refine materials would exclude many crucial projects from benefiting from the credit. He suggested that this limitation goes against the intentions of Congress in fostering a robust domestic supply chain for critical minerals.

The Bigger Picture: Supporting Clean Energy and Domestic Manufacturing

This policy shift reflects a broader push by the U.S. government to bolster clean energy production and reduce reliance on foreign sources of critical minerals. The Section 45X advanced manufacturing production credit is an essential part of the Inflation Reduction Act, which aims to position the U.S. as a leader in the production of clean energy technologies. As the demand for minerals like lithium, nickel, and cobalt grows—critical materials for battery production—the role of domestic mining and refining becomes increasingly important.

Mining companies, however, will need to balance the rebate’s requirements with the investment needed for refining capabilities. Many smaller mining operations may struggle to meet the additional processing requirements, potentially leaving them at a disadvantage compared to larger, more established companies with the necessary infrastructure.

In conclusion, the update to the mining rebate rules marks a step forward in supporting domestic mining and clean energy initiatives but leaves room for further development. The debate over the scope of the credit is likely to continue as stakeholders assess its impact on the industry and its ability to meet the growing demand for clean energy components.

Royal Gold Ecuador Copper Investment of $200 Million Targets Warintza Project

Royal Gold Ecuador copper

Royal Gold Ecuador copper investment reached $200 million as the US metals investment firm's subsidiary RGLD Gold partnered with Canadian miner Solaris Resources for the Warintza copper-gold-molybdenum project. The substantial Royal Gold Ecuador copper investment secures net smelter royalty agreements and gold purchase arrangements for a project containing 1.1 billion tonnes of measured and indicated resources at 0.48% copper equivalent grade, positioning Royal Gold strategically within Ecuador's emerging copper mining sector.

Structured Payment Schedule Aligns with Project Milestones

Royal Gold Ecuador copper investment follows a phased approach with $200 million distributed across three installments tied to development milestones. RGLD Gold will pay $100 million upon closing, $50 million after environmental impact assessment approval and pre-feasibility study publication, and the final $50 million one year after initial closing. This milestone-based structure reduces investment risk while ensuring adequate project funding for critical development phases.

Meanwhile, the investment secures comprehensive royalty agreements covering all metals produced from the Warintza project including copper, gold, and molybdenum. The gold purchase agreement provides Royal Gold additional revenue streams beyond traditional royalty structures. These arrangements create diversified income sources while maintaining exposure to multiple commodity price cycles across the project's operational lifespan.

Warintza Project Resources Support Long-Term Production Potential

However, the Warintza project's substantial resource base of 1.1 billion tonnes at 0.48% copper equivalent grade demonstrates significant scale for potential mining operations. The multi-metal deposit includes copper, gold, and molybdenum mineralization that enhances project economics through commodity diversification. Ecuador's copper mining sector attracts increasing international investment as global copper demand accelerates through energy transition requirements.

Therefore, Royal Gold's investment follows China's Zijin Mining $130 million investment for a 15% stake in Solaris completed in January 2024. The sequential major investments validate Warintza's commercial potential while providing Solaris adequate funding for project advancement. International investor interest demonstrates confidence in Ecuador's mining jurisdiction and the project's technical merits.

Strategic Positioning in Growing South American Copper Market

Furthermore, the Warintza investment positions Royal Gold advantageously within South America's expanding copper production base as global demand accelerates. Ecuador represents an emerging copper jurisdiction with substantial unexplored potential and improving regulatory frameworks for mining development. The country's strategic location provides efficient access to Asian and North American copper markets.

As a result, Royal Gold's streaming and royalty model creates exposure to Warintza's production potential without direct operational responsibilities or capital expenditure requirements beyond the initial investment. This approach enables participation in copper market growth while maintaining diversified portfolio exposure across multiple projects and jurisdictions. The investment strategy aligns with Royal Gold's established business model of financing mining development through royalty arrangements.

The Metalnomist Commentary

Royal Gold's $200 million Warintza investment exemplifies how precious metals streaming companies expand into base metals opportunities, leveraging their financing capabilities to secure royalty positions in high-quality copper projects amid accelerating global demand. The milestone-based payment structure demonstrates sophisticated risk management while Ecuador's emergence as a copper jurisdiction attracts major international investors seeking exposure to South American copper resources essential for global energy transition requirements.

Battery Metals Mining Diesel Disruption Raises New Supply Chain Risk

Battery Metals Mining

Battery metals mining diesel disruption could become an immediate operational risk if the Middle East fuel crisis continues to restrict diesel and gasoil flows. Mining operations that rely heavily on diesel for haulage, transport, drilling, and remote-site activity are the most directly exposed.

The pressure will not affect every part of the battery supply chain equally. Upstream mining faces the clearest fuel availability and cost risk, while refining and processing may feel the impact later through logistics delays, higher freight costs, and reduced primary feedstock availability.

Battery metals mining diesel disruption is most relevant for parts of southern Africa, Australia, and southeast Asia. These regions host major copper, cobalt, lithium, and nickel operations, but their fuel exposure differs sharply by power source, transport route, and mine configuration.

Southern African Copper and Cobalt Face Fuel Logistics Pressure

The DRC and Zambia could face early pressure if diesel flows remain disrupted. Ports in South Africa and Tanzania reportedly had around two months of diesel stock moving inland, but mining operators may need to reduce fuel use by mid-April if the Strait of Hormuz does not reopen soon.

The risk is significant because the copper-cobalt belt depends on diesel for logistics, open-pit haulage, mine-site activity, and some ore concentration processes. The DRC relies heavily on hydroelectricity for power, but diesel generators remain important in areas with limited grid access and for backup supply.

Zambia also plays a crucial logistics role between the copperbelt and key export ports, including Durban. Fuel shortages along these routes could slow truck movements, disrupt concentrate and cathode shipments, and add costs across copper and cobalt supply chains.

Australia Lithium and Indonesia Nickel Show Different Exposure Profiles

Australia appears acutely exposed because it imports most of its diesel from Asia, which in turn depends heavily on Middle East supply. The country has already lowered fuel standards in preparation for supply chain disruption, while cancelled fuel shipments have raised concerns about supply from the second half of April.

Hard-rock lithium mining in Australia could be one of the most fuel-sensitive parts of the battery metals chain. Major spodumene operations such as Greenbushes, Pilgangoora, and Mt Marion rely on diesel for haulage, drilling, and remote-site logistics, even though crushing, grinding, and concentration use more electricity.

Indonesia’s nickel sector is more insulated from immediate fuel disruption because many processing operations rely on captive coal-fired power. However, nickel mining still needs diesel for extraction and internal logistics, while the sector remains exposed to sulfur, sulfuric acid, shipping, and broader energy cost risks.

The Metalnomist Commentary

Battery metals mining diesel disruption shows that energy security is now part of critical mineral security. The market often focuses on ore grades and processing capacity, but fuel logistics can decide whether copper, cobalt, lithium, and nickel supply actually reaches the next stage of the value chain.

Brazil Critical Minerals Investment Outlook Signals Stronger Growth Through 2030

Brazil, Critical Minerals map

Brazil critical minerals investment is set to reach $21.3bn by 2030, according to Ibram. That figure highlights stronger momentum in strategic mining segments across the country. It also shows that critical minerals are gaining a larger share of Brazil’s future mining capital. As a result, Brazil critical minerals investment is becoming a more important driver of national mining strategy.

This growth matters because critical minerals are expanding faster than the rest of the sector. Ibram said critical minerals will account for almost 28pc of total mining investment in 2026-2030. That share reflects a 12.5pc increase from the previous five-year outlook. Therefore, Brazil critical minerals investment is no longer a secondary theme inside the country’s mining industry.

The wider mining sector is also growing from a position of strength. Brazil’s mining industry generated R298.8bn in revenue in 2025, up 10pc from the prior year. Mineral exports also rose 7.1pc to around 431mn metric tonnes. Consequently, the country is entering this investment cycle with stronger production and export momentum.

Copper and Nickel Are Leading the Strategic Capital Shift

Copper investment in Brazil is expected to attract the largest volume of new capital. Ibram projects copper will receive $8.6bn in investment by 2030. That makes copper the biggest single destination for critical minerals funding in the current outlook. As a result, copper investment in Brazil is becoming the core pillar of this expansion.

Nickel also stands out as a major growth area. Ibram expects nickel investment to rise by 24pc in the 2026-2030 period. That places nickel among the fastest-growing strategic mineral categories in the country. Therefore, Brazil critical minerals investment is increasingly tied to energy transition and battery-related materials.

Zinc is projected to grow the fastest in percentage terms. Ibram said zinc investment could rise nearly eleven-fold to $382mn from just $35mn in the earlier period. That increase starts from a smaller base, but it still signals a sharp change in investor interest. Meanwhile, it shows that capital is spreading beyond the largest commodity names.

Rare Earths Remain Attractive Even as Lithium Slows

Rare earth investment in Brazil is also expected to move higher through 2030. Ibram forecasts more than $2.3bn in rare earth investment, up 10pc from the previous outlook. That supports the view that Brazil wants a stronger position in strategic mineral supply chains. Consequently, rare earth investment in Brazil is becoming more relevant to both domestic and international investors.

Not every critical mineral is accelerating at the same speed. Lithium investment is expected to rise by only 0.9pc over the same period. Bauxite investment is projected to decline by 5.4pc, even though both minerals should still attract more than $1.1bn each. Therefore, Brazil critical minerals investment is becoming more selective rather than uniformly bullish.

This selective growth pattern is important for market interpretation. Investors are not simply pouring money into every strategic material category. They are favoring minerals with stronger demand visibility and clearer industrial relevance. As a result, Brazil’s mining investment outlook is becoming more targeted and disciplined.

The Metalnomist Commentary

Brazil’s latest outlook shows that critical minerals are moving closer to the center of its mining future. Copper, nickel, and rare earths now look like the clearest winners in that shift. If project execution matches capital intent, Brazil could strengthen its role as one of the most important strategic minerals suppliers outside the traditional core markets.

China Rare Earth Mining Regulations Tighten as Beijing Targets Illegal Supply

China Rare Earth Mining

China rare earth mining regulations are set to become more detailed as Beijing moves to strengthen control over mining, smelting, recycling and trading activity. The industry and information technology ministry has released a draft plan that would impose administrative penalties of up to 5mn yuan for violations.

China rare earth mining regulations already place rare earth production under a state quota system. The latest proposal would clarify penalty levels for companies that mine, smelt, process or trade rare earth materials outside approved channels.

China rare earth mining regulations are strategically important because China remains dominant across global rare earth mining, separation, metal production and magnet supply. Stronger enforcement could tighten unofficial supply and improve state oversight of material flows.

The draft plan released on 28 April sets clearer benchmarks for discretionary penalties. It is aimed at illegal mining, unauthorised smelting, quota breaches, unapproved feedstock use and failures in reporting or traceability.

Quota Enforcement Extends Across Mining, Smelting and Recycling

The draft plan targets enterprises that produce rare earth products beyond state-allocated mining quotas. Companies that conduct smelting without approved quotas would also face fines.

The rules would also cover comprehensive recycling firms that use rare earth ore as feedstock without authorisation. This is important because recycling and secondary processing can become loopholes if ore origin and flow reporting are weak.

Companies that buy, process or sell illegally produced rare earth ore or smelting products would also be penalised. This widens enforcement from producers to the broader trading and processing chain.

Firms that fail to comply with rare earth flow reporting and traceability requirements would face penalties. Companies that refuse or obstruct government supervision and inspection would also be targeted.

This shows that Beijing is not only regulating output volumes. It is building a more detailed control system around material origin, movement, processing rights and end-market access.

Rare earth traceability is becoming more important because these materials are strategic inputs for electric vehicles, wind turbines, robotics, defence systems, aerospace, electronics and high-end manufacturing.

The policy also strengthens China’s ability to monitor both primary and secondary supply. That matters as rare earth scrap recycling grows and as downstream magnet demand continues to increase.

State Control Reinforces China’s Strategic Rare Earth Position

China has tightened control over rare earth resources for more than a decade. The sector has been consolidated under several large state-owned groups to reduce illegal mining, improve environmental oversight and strengthen industrial coordination.

The State Council issued comprehensive rare earth regulations on 29 June 2024 covering mining, smelting, processing, recycling, trading and imports and exports. Those rules took effect on 1 October 2024, but did not define detailed penalty levels.

The latest draft fills that gap. It turns broad regulatory control into a more enforceable administrative system with clearer financial consequences.

China’s two major rare earth groups, Northern Rare Earth and China Rare Earth, now control domestic resources after China Rare Earth consolidated Xiamen Tungsten and Guangdong Rare Earth. Mining, smelting and separation quotas are allocated only to these groups and their affiliates.

Private firms and individuals are prohibited from processing rare earths. This gives Beijing a high level of control over domestic supply channels and industrial output.

From 2025, China also included imported rare earth ore in its quota system. This expanded oversight beyond domestic mining and gave the government more control over imported feedstock entering Chinese smelting and separation plants.

The move is strategically significant. China is treating rare earths as controlled industrial resources rather than ordinary commodities. Production discipline, traceability and export controls are now part of the same policy framework.

For global buyers, tighter regulation could reduce illegal or informal supply flows. It may also increase dependence on approved producers and make rare earth availability more closely tied to Chinese quota and export policy.

The Metalnomist Commentary

China’s rare earth enforcement push shows that Beijing wants full visibility over every stage of the value chain. For western buyers, the risk is clear: rare earth supply is becoming more regulated, more traceable and more politically controlled at the source.

CATL Rio Tinto Partnership Targets Mining Electrification and Battery Circularity

CATL

CATL Rio Tinto partnership plans could accelerate electrification across Rio Tinto’s global mining operations as the metals sector looks for practical ways to cut emissions. The two companies have signed a non-binding agreement to explore cooperation in battery technologies, system integration, recycling, and new energy solutions.

The CATL Rio Tinto partnership connects one of the world’s largest battery producers with a major global supplier of iron ore, copper, aluminium, and lithium. This creates a direct link between upstream resource extraction and the battery systems needed to decarbonise mining fleets, rail, and industrial energy use.

Rio Tinto wants to develop a zero-carbon mining model with global demonstration value. CATL will support that goal through its battery technology, energy system expertise, and experience in large-scale electrification.

Battery Systems Move Deeper Into Mining Operations

Mining electrification is becoming a strategic priority because diesel-powered equipment remains a major source of operating emissions. Battery systems can support electric haul trucks, heavy equipment, rail locomotives, site power systems, and charging infrastructure.

The collaboration could help Rio Tinto improve operating efficiency while reducing carbon intensity. Electrified mining systems may also lower fuel exposure, improve maintenance economics, and support customers that increasingly demand lower-carbon raw materials.

The agreement also reflects a broader shift in mining procurement. Large miners are no longer only buying equipment; they are building partnerships around batteries, energy management, recycling, and circular material flows. This gives battery companies a larger role in mining’s industrial transition.

Critical Minerals Circularity Becomes a Strategic Link

The CATL Rio Tinto partnership will also explore business models for battery materials recycling and critical minerals circularity. This is important because mining electrification will create new demand for lithium, copper, nickel, graphite, rare earths, and other battery-linked materials.

Circularity can help reduce waste and strengthen supply security. If battery materials can be recovered and reused across mining operations, companies can reduce dependence on fresh raw material inputs and build more resilient supply chains.

CATL and BYD are increasingly targeting partnerships with major miners and energy companies. CATL and BYD have already signed agreements with BHP to develop battery solutions for mining equipment and railway locomotives, while BYD has also agreed to work with Aramco on electric and fuel cell vehicle technologies.

The Metalnomist Commentary

Mining electrification is becoming a new battleground for battery companies, miners, and equipment suppliers. The strategic winners will be those that can connect mineral supply, battery deployment, recycling, and low-carbon operations into one industrial ecosystem.

Mining states smelter economics drive shift toward regional value chains

Africa Mining

Mining states smelter economics are reshaping how resource-rich governments think about value addition and industrial policy. At the FT Metals and Mining conference, African and Middle Eastern officials outlined ambitious mining growth plans while acknowledging tough smelter economics. As a result, they increasingly favour flexible regional chains, trading platforms and targeted downstream moves over politically symbolic but uneconomic smelter projects.

Zambia and Saudi Arabia recalibrate mining growth and downstream strategy

Mining states smelter economics sit at the heart of Zambia’s long-term copper strategy. The government is holding to its 3mn t/yr copper target by 2031 but plans to stay out of smelter investment decisions. Instead, Zambia will focus on policy tools such as export waivers and a state-run trading house from Lusaka. These mechanisms aim to manage excess copper concentrate and attract private capital into processing where returns justify risk.

However, Zambia still needs major capital commitments to reach its copper goals. The country produced 840,000t of refined copper last year and expects to exceed 1mn t in 2025. To close the gap with its 2031 ambition, Zambia is relying on projects like First Quantum’s $1.25bn Kansanshi expansion and other greenfield or brownfield investments. Therefore, mining states smelter economics will influence whether future capacity focuses on concentrate exports, tolling deals or selective domestic refining.

Meanwhile, Saudi Arabia is building mining into its third economic pillar under Vision 2030. The kingdom wants to raise sector GDP from $35bn to $75bn by 2035, with 70pc from downstream activities. It is rolling out a fully integrated aluminium chain, planning to triple phosphate output by 2040 and constructing a battery metals trading platform. These moves show how mining states smelter economics can support more sophisticated value chains rather than simple ore exports.

Saudi Arabia is also using international deals to secure feedstock and technology. Its PIF-backed Manara Minerals JV is investing abroad, while the kingdom builds rare earth links with partners such as MP Materials and explores refinery projects with global miners. As a result, the country is positioning itself as a regional processing and trading hub, rather than relying solely on domestic ore extraction.

Regional chains rise as smelter economics and policy risks bite

Mining states smelter economics are driving governments to prioritise regional infrastructure over isolated national hubs. Guinea’s $20bn Simandou iron ore project illustrates this shift, combining Chinese rail capacity, US locomotives and French signalling in a single integrated corridor. This model aligns with calls from industry leaders to optimise at regional scale, where transport, energy and port infrastructure can support multiple producers and customers.

However, building new smelters remains challenging when copper treatment charges sit at historically weak or even negative levels. Industry voices argue that in-country smelting often “doesn’t pay” in today’s market, especially once high power costs and carbon considerations are included. Therefore, mining states smelter economics are pushing policymakers to abandon hopes of easy “green premiums” and focus instead on cost competitiveness and stable regulatory frameworks.

At the same time, state miners are exploring commercial tools to capture more value without over-investing in heavy assets. In the Democratic Republic of Congo, Gecamines plans a dedicated trading arm to market its 20–49pc joint-venture production share. The company wants to revive its own brand, sharpen market knowledge and improve pricing power. If logistics and finance constraints ease, executives believe the firm could “easily” join the top tier of global copper operations.

The Metalnomist Commentary

The debate around mining states smelter economics is shifting from ideology to hard numbers. Resource-rich governments increasingly recognise that modern value chains may rely more on trading hubs, corridors and selective downstream assets than on politically attractive but uneconomic smelters. For investors, the most attractive jurisdictions will be those that match geological potential with pragmatic policies on infrastructure, energy and fiscal stability.

NIU Group Copper Acquisition Expands Footprint in Chilean Mining Sector

Minera Tres Valles

The NIU Group copper acquisition of Chilean producer Minera Tres Valles (MTV) signals a bold entry into South America’s copper supply chain. MTV currently produces 5,000 tonnes per year (t/yr) of copper, with plans to scale to 13,000–15,000 t/yr by 2026. NIU aims to capitalize on copper's critical role in the global energy transition.

MTV’s Growth Potential Attracts Strategic Investment

NIU Group, a European investment firm founded by Austrian investor Cevdet Caner, has committed to expanding MTV's operations. MTV holds 460km² of mining rights in Chile’s copper-rich region, of which only 5% has been explored. Proven and probable reserves currently stand at 8.2 million tonnes. NIU will inject capital to ramp up development and increase production volumes.

The acquisition includes MTV’s integrated processing plant, offering NIU an efficient and scalable platform to supply growing global copper demand. Copper remains essential for electrification infrastructure, renewable energy systems, and electric vehicles, aligning with NIU's energy transition investment strategy.

NIU Sets Sights on Global Mining Expansion

While the NIU Group copper acquisition in Chile marks a key step, the firm plans to broaden its mining asset portfolio globally in 2025. This positions NIU to secure upstream materials critical to energy transformation initiatives in Europe and beyond.

The acquisition reflects growing investor interest in mining assets, particularly those supporting low-carbon technologies. Financial terms of the MTV deal were not disclosed, but the strategic intent is clear: control supply chains for critical minerals amid tightening global competition.

The Metalnomist Commentary

The NIU Group copper acquisition illustrates how private capital is targeting upstream resources to gain influence over decarbonization supply chains. MTV’s underexplored reserves and scalable output offer long-term upside aligned with global copper demand trajectories.
