Aclara Brazil Rare Earths Pilot Plant Launches to Bolster Global Supply Chain

Aclara Resources

The Aclara Brazil rare earths pilot plant has officially started operations, marking a strategic milestone for critical mineral development in South America. Aclara Resources, a Canadian-based mining firm, invested R30mn ($5.3mn) to develop the pilot facility in Nova Roma, located in Brazil’s Goias state. The semi-industrial scale plant will process 250 metric tonnes per year of ionic clays, producing concentrate with over 95% purity.

Supplying Rare Earths for the EV Revolution

Aclara’s plant will extract both heavy and light rare earth elements, including dysprosium, terbium, neodymium, and praseodymium. These metals are essential to electric vehicle (EV) production, wind turbines, and high-performance magnets. Aclara stated the plant could support the manufacturing of up to 5 million EVs annually. The company emphasized its environmentally responsible extraction process as part of its commitment to sustainable mining.

Brazil Emerges as a Rare Earths Powerhouse

Brazil continues to attract investment in rare earth and critical mineral projects. Production at Mineracao Serra Verde’s Goias facility, with a 5,000t/year rare earth oxide capacity, began in late 2023. With the Aclara Brazil rare earths pilot plant now operational, Brazil strengthens its position as an emerging alternative to China in the global rare earth supply chain.

The Metalnomist Commentary

The launch of the Aclara Brazil rare earths pilot plant highlights Brazil’s increasing relevance in the global critical mineral landscape. As countries seek diversified rare earth sources, Brazil’s sustainable projects will play a key strategic role in decarbonization and supply security.

Brazil India Critical Minerals Deal Targets Rare Earths and Supply Chain Resilience

Brazil-India rare earth

Brazil India critical minerals deal marks a strategic step toward deeper cooperation in rare earths, battery materials, and mineral extraction technology. The agreement reflects a shared effort to reduce supply-chain exposure, support clean energy industries, and build alternative sources outside China-dominated processing networks.

The bilateral agreement, signed on 21 February, will support cooperation in critical minerals and rare earths. Brazil and India plan to develop both countries’ mineral industries while exchanging technologies to improve extraction and resource development. For India, the deal supports its push to reduce dependence on China. For Brazil, it strengthens efforts to turn large mineral reserves into higher-value industrial supply chains.

Brazil India critical minerals deal also fits a wider geopolitical shift. Governments are no longer treating rare earths, lithium, and other strategic minerals as ordinary commodities. They are becoming tools of industrial policy, energy security, and technology competitiveness.

Rare Earths Cooperation Strengthens India’s Diversification Strategy

India is seeking more resilient supply chains for minerals used in renewable energy, batteries, electronics, defence, and advanced manufacturing. Cooperation with Brazil gives India access to a resource-rich partner with significant reserves of critical minerals and rare earths.

This matters because rare earths are difficult to develop at scale. Mining is only one part of the challenge. Separation, refining, metallurgical processing, and environmental controls are often bigger bottlenecks. Therefore, technology exchange between Brazil and India could become as important as raw material access.

The agreement also supports India’s broader industrial strategy. As India expands electric mobility, battery manufacturing, renewable energy, and electronics production, secure mineral supply will become a competitiveness issue. The Brazil India critical minerals deal gives New Delhi another route to reduce concentration risk in its future supply base.

Lithium Trade Signals a Broader Minerals Partnership

Recent lithium activity shows that Brazil-India mineral cooperation is already moving beyond diplomatic language. Indian battery cathode manufacturer Altmin recently purchased a 33pc stake in Brazilian lithium producer CBL’s refinery for $40mn. Altmin also secured an offtake agreement for 5,000 t/yr of lithium carbonate.

This transaction highlights how investment and offtake can turn critical minerals policy into actual supply-chain capacity. Brazil has lithium resources and refining potential, while India has rising demand from battery and cathode industries. That creates a natural partnership if both countries can align financing, processing standards, and long-term procurement.

The wider trade target reinforces the strategic direction. Brazil and India expect bilateral goods trade to reach up to $20bn/yr by 2030, compared with $15bn/yr in 2025. Critical minerals, rare earths, lithium, renewable energy, defence, and commerce could all become part of a broader industrial corridor between the two economies.

The Metalnomist Commentary

The Brazil India critical minerals deal shows how emerging economies are building their own mineral alliances instead of relying only on Western-led frameworks. The key question is whether Brazil and India can move from resource diplomacy to processing capacity, bankable projects, and reliable offtake.

Atlas Lithium rare earths in Brazil reshape its critical minerals story

Atlas Lithium

Atlas Lithium rare earths in Brazil mark a major strategic shift for the US-listed lithium developer. The company has identified rare earth deposits at its Ipora and Alto do Paranaiba projects, adding ionic clay and sedimentary rock resources to its portfolio. This Atlas Lithium rare earths in Brazil announcement broadens its exposure beyond brine and hard-rock lithium into magnetic and heavy rare earths.

The Ipora project in Goias has emerged as an important ionic clay discovery. Initial drilling shows 2,071ppm total rare earth oxides (Treo), including 775ppm magnetic rare earth oxides, positioning Atlas Lithium rare earths in Brazil within a competitive grade range. As a result, the project stands out for its heavy rare earth oxide recovery rate of 55pc and yttrium recovery at 63pc, both attractive metrics for downstream magnet and electronics supply chains.

Alto do Paranaiba links rare earths with titanium credits

Alto do Paranaiba in Minas Gerais adds a very different style of mineralisation. The project hosts near-surface Treo grades up to 28,870ppm alongside 23.3pc titanium dioxide, pointing to potential by-product titanium value. Therefore Atlas Lithium rare earths in Brazil now span both ionic clays and high-grade sedimentary units, which can diversify processing options and revenue streams.

However, the company still needs to confirm continuity, metallurgy and scalable mine plans at Alto do Paranaiba. Near-surface grades offer potential for lower strip ratios and faster development, but sediment-hosted rare earths require careful flowsheet design. Investors will focus on how Atlas prioritises drilling, pilot testing and sequencing between Ipora and Alto do Paranaiba.

Building a multi-commodity critical minerals platform

Atlas Critical Minerals, the company’s Brazilian subsidiary, now controls more than 218,000 hectares of mineral rights across rare earths, titanium, graphite and uranium. This scale provides optionality for partnerships and off-take, especially as Western buyers seek non-Chinese rare earth sources. Meanwhile, combining Atlas Lithium rare earths in Brazil with its lithium portfolio could position the group as an integrated critical minerals developer rather than a single-commodity play.

As a result, Atlas can align its narrative with supply-chain diversification, energy transition and defence applications. But execution risk remains high, given early-stage status, capital needs and complex permitting in Brazil. Clear timelines, resource updates and metallurgical results will determine whether these discoveries translate into bankable projects.

The Metalnomist Commentary

Atlas is moving quickly to rebrand itself from a pure lithium story into a broader critical minerals platform. The rare earth discoveries are promising, particularly the ionic clay potential at Ipora, but still sit firmly in the exploration risk bucket. For now, these finds strengthen strategic optionality and headline appeal more than near-term cash flow.

Brazil Rare Earth Project Advances as Mosaic and Rainbow Target Phosphogypsum Recovery

Brazil, Mosaic rare earth

Brazil rare earth project development is gaining momentum after Mosaic and Rainbow Rare Earths agreed to advance a new rare earth elements facility in Uberaba, Brazil. The proposed project would recover rare earths from phosphogypsum, turning an industrial by-product from fertilizer production into a potential source of strategic magnet materials.

The companies plan to negotiate a definitive agreement for a jointly owned project company. The venture would build a processing facility in Uberaba, located in Minas Gerais state, subject to feasibility study results. Construction is currently scheduled for 2027.

The Brazil rare earth project is strategically important because it links fertilizer value chains with critical mineral supply. Mosaic brings access to phosphate-related material streams, while Rainbow Rare Earths brings technology and project experience in recovering rare earth elements from phosphogypsum.

Phosphogypsum Recovery Could Add New Supply Outside Traditional Mining

The proposed facility would process about 2.7 million tonnes per year of phosphogypsum, according to the economic assessment. This feedstock route is different from conventional rare earth mining because it focuses on recovering value from existing industrial material rather than opening a new primary mine.

The facility is expected to produce around 1,900 tonnes per year of separated neodymium and praseodymium oxide. These materials are essential for high-performance permanent magnets used in electric vehicles, wind turbines, robotics, industrial motors, and advanced electronics.

The project would also produce about 600 tonnes per year of samarium, europium, and gadolinium-rich products. These medium and heavy rare earth elements are important because supply chains for heavier rare earths remain more concentrated and strategically sensitive.

Brazil Strengthens Its Position in Critical Minerals Supply Chains

The Brazil rare earth project could strengthen the country’s role in global critical minerals supply. Brazil already has major mining, fertilizer, and industrial raw material assets, and phosphogypsum recovery could create a new pathway into separated rare earth products.

For Mosaic, the agreement could unlock additional value from phosphate operations and support a broader circular economy model. For Rainbow Rare Earths, the Uberaba project expands its phosphogypsum recovery strategy beyond its Phalaborwa project in South Africa.

The project also reflects a wider market shift. Rare earth supply chains are no longer focused only on mining ore. Processing technology, secondary recovery, industrial waste valorisation, and separated oxide capacity are becoming central to supply security.

The Metalnomist Commentary

This project matters because it treats fertilizer waste as a strategic mineral resource. If the feasibility study supports commercial development, Brazil could become a more relevant player in rare earth separation and magnet material supply.

Brazil rare earths Rio Grande Rise: offshore claim targets critical minerals

Brazil

Brazil rare earths Rio Grande Rise ambitions intensify as its UN claim advances. Brazil rare earths Rio Grande Rise could unlock a vast offshore resource. Brazil rare earths Rio Grande Rise also reinforces the nation’s Blue Amazon strategy. Officials aim to expand rights over mining, energy, and fisheries.

Offshore scope and resource potential

The Rio Grande Rise spans about 500,000km² in the South Atlantic. It sits roughly 1,200km off Rio Grande do Sul. Studies flag rare earths alongside red clays, basalt, and manganese crusts. These deposits include NdPr, Dy, Tb, and other magnet metals. Therefore, Brazil sees high-value opportunities for batteries and clean tech.

Brazil already holds significant rare earth reserves onshore. The claim could extend access into a new marine province. Meanwhile, UNCLOS procedures guide shelf limits and sovereign rights. If approved, Brazil gains stronger control over exploration. That would accelerate investment screening and early baseline surveys.

Strategic stakes for supply chains and energy

The bid aligns with Brazil’s Blue Amazon development plan. The plan spans offshore minerals, renewables, and hydrocarbons. Global rare earth reserves reached 130mn tonnes in 2023. Brazil holds about 16%, behind Vietnam and tied with China. As a result, diversified offshore feed could bolster security of supply.

Downstream industries need stable magnet and catalyst inputs. EVs, wind turbines, and electronics drive that demand. However, environmental safeguards and data transparency remain vital. Therefore, Brazil must balance exploration with marine stewardship.

The Metalnomist Commentary

This seabed push is about leverage, not near-term output. The value lies in optionality during tight rare earth cycles. Watch UN milestones, baseline ecology work, and any pilot sampling plans.

Brazil Rare Earths Coalition Aims to Unlock Domestic Supply

Brazil Rare Earths

Brazil’s new Brazil rare earths coalition seeks clear rules and sovereignty over critical minerals. The Brazil rare earths coalition will draft a regulatory benchmark, promote strategic debates, and align geology with industry. As a result, the Brazil rare earths coalition targets faster projects, stronger local processing, and secure supply chains.

Regulatory focus ties geology to industry

Lawmakers plan a framework that accelerates exploration and builds midstream capacity. Therefore, Brazil can move beyond raw ore exports. Today, production is nascent, with Serra Verde as the only producer outside Asia. However, Brazil holds 23% of global reserves, according to SGB. Clear rules could attract capital and de-risk permitting.

Processing gap and offshore ambitions

Processing remains concentrated in China, so Brazil must localize separations. Consequently, policy will likely prioritize refineries for NdPr, Dy, and Tb. Meanwhile, officials also pursue the Rio Grande Rise claim. If successful, offshore resources could diversify feedstock. Still, onshore ionic clay projects will move first on timelines.

The Metalnomist Commentary

Brazil’s opportunity hinges on midstream execution, not geology. To matter globally, Brasília must pair permitting reform with incentives for separation plants and long-term offtakes that anchor financing.

Serra Verde Rare Earth Financing Strengthens Brazil’s Position in Heavy Rare Earth Supply

DFC, Brazil

Serra Verde rare earth financing marks a major strategic step for Brazil’s rare earth industry. The US International Development Finance agency has provided a $565mn package to Serra Verde. The funding includes an option for the US government to take a minority equity stake. As a result, Serra Verde rare earth financing now carries both industrial and geopolitical weight.

This matters because Serra Verde is already producing from its Pela Ema ionic clay deposit in Brazil. The operation entered commercial production in 2024 and currently produces 5,000 t/yr of total rare earth oxides. Its output includes dysprosium, erbium, neodymium, and praseodymium. Therefore, Serra Verde rare earth financing supports an existing project rather than a distant concept.

The funding also arrives at a time when western governments are moving more aggressively into critical minerals. Recent DFC activity has already expanded into copper, tungsten, and other strategic materials. Consequently, Serra Verde rare earth financing fits a much broader push to secure non-Chinese supply routes.

Brazil Rare Earth Project Gains Capital for Expansion and Strategic Relevance

The Brazil rare earth project will use the funding to refinance existing loans and expand capacity. Serra Verde aims to raise output to 6,500 t/yr of total rare earth oxides by 2027. That increase may look modest in absolute terms, but it matters in a market where diversified rare earth supply remains scarce. As a result, the Brazil rare earth project gains both financial flexibility and a clearer growth path.

The ionic clay nature of the deposit adds further importance. Ionic clay rare earths are especially relevant because they can contain valuable magnet and heavy rare earth elements. That makes Serra Verde more strategically attractive than a simple bulk rare earth project. Therefore, Serra Verde rare earth financing strengthens a part of the supply chain that many western buyers want to expand.

The equity option also deserves attention. A financing structure that includes a possible government minority stake suggests unusually strong strategic interest. This is not only about debt support or project refinancing. Meanwhile, it signals that Brazil’s rare earth sector is moving closer to formal alignment with western supply chain security goals.

Heavy Rare Earth Supply Diversification Gives Brazil More Strategic Value

Heavy rare earth supply remains one of the most sensitive areas in the critical minerals market. Dysprosium and similar elements are essential for advanced magnets and high-performance industrial uses. Projects that can produce these materials outside concentrated supply chains attract far more attention than simple reserve size alone. Consequently, Serra Verde rare earth financing helps position Brazil more clearly in the strategic supply map.

Brazil’s wider resource base reinforces that story. The country holds one of the world’s largest rare earth reserve positions and is already drawing more developer attention. Companies such as Aclara, Brazilian Rare Earths, and Meteoric are also advancing projects there. Therefore, Serra Verde rare earth financing may become a signal for broader investment momentum across Brazil.

The broader implication is clear. Supply chain diversification is no longer only about finding resources. It is about financing operating projects, expanding production, and tying new supply into aligned trade relationships. As a result, Brazil is becoming more important not just as a resource holder, but as a future processing and supply partner.

The Metalnomist Commentary

This deal matters because it supports a producing rare earth asset with real expansion potential. Serra Verde is now moving beyond startup status and into strategic scale-up territory. If output rises as planned, Brazil could gain a much stronger role in non-Chinese rare earth supply over the next few years.

China to Overpower Brazil in Rare Earths Through 2050

Brazil in Rare Earths

China to overpower Brazil in rare earths as processing capacity stays highly concentrated in China. Brazil holds vast reserves, but processing lags. Therefore, China to overpower Brazil in rare earths remains the base case through 2050. Brazil eyes offshore and onshore reserves to raise output. However, processing bottlenecks still define market power.

Processing Dominance Shapes Market Power

China to overpower Brazil in rare earths reflects processing, not geology. China handled 90% of rare earth processing in 2022. Malaysia held 9% and Estonia 1%. Meanwhile, China produced 68% of rare earths in 2022. The US and Australia followed at 11% and 9%. IEA sees China’s magnet REE mine supply up 24% by 2035. Australia may quadruple output to 14,570t by 2035. Yet processing concentration keeps China’s strategic lead intact.

Brazil’s Resource Scale Meets Early-Stage Industry

Brazil holds 23% of global rare earth reserves. It also holds 26% of graphite and 94% of niobium. Even so, commercial production is nascent. Serra Verde is Brazil’s only REE producer today. New entrants target Brazil’s clays and carbonatites. REA and Aclara plan Dy, Tb, and NdPr projects. Government ambitions include the Rio Grande Rise offshore. Success still requires midstream plants and clean leach circuits.

The Metalnomist Commentary

Processing remains the real chokepoint, not reserves. Brazil’s path runs through solvent extraction investment and ESG-credible reagents. Watch pilot circuits, offtakes, and financing signals that enable non-China midstream scale.

Brazil Critical Minerals Processing Moves Closer to a US-Backed Expansion

US, critical minerals in Brazil

Brazil critical minerals processing is moving closer to a new strategic phase. The United States is now openly discussing financing and technical support for Brazil critical minerals processing. Washington sees Brazil as an essential partner in a more resilient Western supply chain. As a result, Brazil critical minerals processing is becoming a serious geopolitical and industrial priority.

This shift matters because Brazil has large reserves but limited downstream scale. The country holds major positions in niobium, rare earths, graphite, nickel, and lithium. Yet Brazil still contributes only a small share of global rare earth production. Therefore, the next stage of the market will depend less on geology and more on industrial buildout.

The US focus appears especially clear in heavy rare earths. Projects such as Serra Verde and Aclara already show where this strategy may go. Both are tied to mixed rare earth products with higher dysprosium and terbium content. Consequently, heavy rare earth processing in Brazil is becoming more central to future magnet supply chains.

US-Brazil Critical Minerals Partnership Is Moving Beyond Mining

US-Brazil critical minerals partnership is now shifting from resource interest toward processing ambition. US officials said financing from the Development Finance Corporation and technical cooperation could support that next step. That matters because processing is where more value stays inside the supply chain. As a result, Brazil is being positioned as more than a raw materials source.

This approach also fits wider US strategy in Latin America. Washington has already signed critical minerals agreements with several regional partners. Brazil stands out because of its resource scale and industrial sophistication. Therefore, it offers stronger conditions for building midstream capacity than many other jurisdictions.

However, the political structure will matter. Brazil would still need to allow foreign-backed processing development on its territory. That means any real progress will require policy alignment as well as financing. Meanwhile, both governments appear to understand that strong partnerships will decide whether this vision becomes real.

Brazil Rare Earth Value Chain Depends on Industrialization, Not Exports Alone

Brazil rare earth value chain expansion is also a domestic political priority. President Lula has made it clear that Brazil does not want to remain a simple exporter of critical minerals. He wants foreign companies to build downstream industry inside the country. That message aligns closely with demands from Brazilian market participants.

The same logic applies beyond rare earths. Lithium producers and industry groups also want policies that support a full end-to-end value chain. They argue Brazil has the resource base to become a global critical minerals leader. However, the country still lacks stronger fiscal incentives for midstream and downstream investment. Therefore, Brazil critical minerals processing may advance only if industrial policy becomes more competitive.

That is why current US interest matters so much. External financing can help, but it cannot replace local policy support. If Brazil combines foreign capital with domestic industrial incentives, it could move far higher in the global value chain. As a result, Brazil rare earth value chain development may become one of the most important critical minerals stories in the Americas.

The Metalnomist Commentary

Brazil now faces a clear strategic choice. It can stay rich in reserves but light in processing, or it can push deeper into value-added industry. If US backing and Brazilian industrial policy move together, Brazil could become one of the West’s most important critical minerals processing hubs.

Brazil Critical Minerals Mapping Gains IDB Support for Graphite, Rare Earths and Lithium

IDB(the Inter American Development Bank)

Brazil critical minerals mapping will gain international support after the Brazilian Geological Service and the Inter-American Development Bank agreed to work together on a new geological data project. The program will focus on minerals linked to the energy transition and advanced technology supply chains.

The IDB will invest $890,000 over three years, using resources from Japan’s special fund with the bank. The project will generate public data on graphite, rare earths, and lithium reserves across Brazil.

Brazil critical minerals mapping matters because the country holds one of the strongest undeveloped mineral positions in the global energy transition. Brazil has the world’s largest niobium reserves and production, while also ranking second in rare earths and graphite reserves, third in nickel, and sixth in lithium.

Public Geological Data Could Strengthen Brazil’s Mineral Strategy

The mapping project gives Brazil a stronger technical foundation for future exploration, investment screening, and industrial policy. Public geological data can reduce early-stage uncertainty for investors while helping the government understand which regions have the strongest development potential.

Graphite, rare earths, and lithium are strategically important because they support batteries, permanent magnets, electric vehicles, renewable energy systems, electronics, and defense-related technologies. Better mapping could help Brazil move from resource potential to project development.

The involvement of Japan’s special fund also carries strategic weight. Japan has a strong interest in diversified critical mineral supply chains, especially in rare earths and battery materials where global processing remains highly concentrated.

Mapping Supports Lula’s Push for Domestic Processing

Brazil critical minerals mapping also aligns with President Luiz Inácio Lula da Silva’s tougher stance on mineral value creation. Lula has resisted foreign agreements that do not include commitments to build processing and refining capacity inside Brazil.

This position makes geological mapping more than a resource survey. It becomes part of a broader strategy to negotiate from a stronger position and avoid remaining only a raw mineral exporter.

For foreign partners, the message is clear. Brazil may welcome capital and technical cooperation, but access to critical minerals will increasingly depend on support for domestic processing, refining, and industrial development.

The Metalnomist Commentary

Brazil’s mapping partnership with the IDB is a small investment with large strategic meaning. If Brazil connects better geological data with processing policy, it could become one of the few countries able to offer both critical mineral scale and domestic value-chain development.

Viridis Rare Earth Output Marks First Step Toward Brazil Magnet Materials Supply

mixed rare earth carbonate

Viridis rare earth output from its Poços de Caldas demonstration plant marks an important milestone for Brazil’s emerging role in non-China rare earth supply. Australia-based Viridis Mining and Minerals has produced its first batch of high-grade mixed rare earth carbonate in Minas Gerais.

Viridis rare earth output comes from a newly commissioned demonstration plant that processes 100 kg/hr of ionic clay feedstock. The product includes magnet-related rare earths such as neodymium, praseodymium, dysprosium and terbium.

Viridis rare earth output is strategically important because mixed rare earth carbonate is an intermediate product that can feed separation, oxide refining and eventually permanent magnet supply chains. The achievement moves the Colossus project from resource potential into early process validation.

The company has sent samples to the Australian Nuclear Science and Technology Organisation for qualification. It is still in discussions with potential offtake partners for its mixed rare earth carbonate.

Colossus Ionic Clay Project Gains Processing Momentum

The demonstration plant draws feedstock from the northern concession pits of Viridis’ nearby Colossus ionic clay project. Colossus contains a 200mn t reserve grading 2,640ppm total rare earth oxides.

That resource base gives the project strategic relevance. Ionic clay rare earth deposits can be important because they may contain valuable heavy rare earths used in high-performance magnets.

The presence of dysprosium and terbium matters especially. These heavy rare earths improve magnet performance under heat and stress, making them important for electric vehicles, wind turbines, robotics, aerospace and defence systems.

Viridis plans to build a commercial-scale plant at Colossus and is targeting first production in 2028. But the company has not yet confirmed a construction timeline.

Financing support is building around the project. Colossus has received A$50mn in loans from Export Finance Australia, along with funding commitments from Brazilian public finance institutions.

The project has also received a $100mn letter of interest from Export Development Canada and support from French export credit agency Bpifrance Assurance Export. This shows that allied governments are willing to support rare earth projects outside China.

Brazil Builds a Broader Rare Earth Processing Platform

Viridis is not only developing Colossus as a mining project. It is also planning rare earth oxide refining and magnet recycling capacity at the same Poços de Caldas location through a joint venture with Ionic Rare Earths.

That integrated approach matters. Rare earth supply chains need more than mining and carbonate production. They require refining, separation, recycling, metal-making, alloying and magnet qualification.

Brazil could become more important if it can connect resource development with processing and downstream material production. The country already has mineral potential, but the value will depend on building customer-ready products.

The Poços de Caldas site could therefore become a rare earth materials hub if the demonstration work, qualification process and future commercial plant progress as planned.

For magnet users, Brazil offers a potential alternative source of rare earth intermediates at a time when China still dominates processing and permanent magnet supply.

The next challenge is commercialisation. Viridis must qualify its product, secure offtake partners, complete project financing and prove that Colossus can scale from demonstration output to reliable industrial supply.

The Metalnomist Commentary

Viridis’ first rare earth output is small in volume but important in direction. Brazil’s rare earth opportunity will depend on whether projects like Colossus can move beyond resource statements into qualified carbonate, refined oxides and magnet-ready supply.

Viridis Doubles Brazil Rare Earths Estimate, Extending Colossus Mine Life

Viridis Mining and Minerals

Viridis doubles Brazil rare earths estimate to 200mn tonnes at the Colossus Project. Viridis doubles Brazil rare earths estimate by converting measured and indicated resources. Therefore, Viridis doubles Brazil rare earths estimate and signals a potential 40-year operating horizon. The ionic adsorption clay deposit in Minas Gerais averages 2,640ppm TREO with 740ppm MREO. The mine plan prioritizes NdPr, dysprosium, and terbium to maximize basket value.

Reserve scale, grade mix, and pricing assumptions

Viridis increased reserves to 200mn tonnes, up from 98.5mn tonnes. The company derived the upgrade exclusively from higher-confidence categories. As a result, execution risk moderates ahead of financing. The deposit’s 2,640ppm TREO includes 740ppm magnetic oxides. Meanwhile, pricing assumptions anchor economics at $90/kg NdPr. Dysprosium uses $269/kg, and terbium uses $888/kg. These markers frame sensitivity for basket value and payback.

Throughput, carbonate output, and offtake progress

The Colossus Project targets 5mnt per year of ore. Management expects 10,000–12,000t per year of mixed rare earth carbonate. Consequently, scale supports multi-year offtake programs. Viridis advances discussions on offtake with strategic buyers. Therefore, downstream partners can align on NdPr and heavy magnet needs. The firm continues technical work toward a final investment decision.

The Metalnomist Commentary

Ionic clay deposits can deliver low-acid, short-cycle production, yet metallurgy matters. Pay close attention to impurity control, reagent recycling, and heavy rare earth recoveries. Offtake structure and processing route selection will define long-term margins.

Brazil Parnaiba basin rare earths discovery highlights Piaui REE, phosphate, and uranium potential

Brazil, SGB

Brazil Parnaiba basin rare earths discovery signals a new resource story in Piaui. The Brazil Parnaiba basin rare earths discovery points to near-surface mineralization that could lower exploration risk. As a result, investors will watch how quickly Brazil converts assays into defined resources.

Brazil’s Geological Service SGB reported high concentrations of rare earth elements, phosphate, and uranium in the Parnaiba basin. The work focused on the basin’s eastern area in northeastern Piaui state. Meanwhile, the combination of REE and phosphate adds strategic value for industrial supply chains.

Why heavy rare earths matter for magnets and defense supply chains

Heavy rare earths drive performance in high-temperature permanent magnets. Dysprosium improves heat resistance in electric motors and wind turbines. Therefore, any new heavy REE corridor matters for energy transition and defense procurement.

SGB’s chemical work indicates heavy rare earths including dysprosium, erbium, ytterbium, and yttrium. The reported range reaches 259ppm to 2,188ppm in the eastern basin. Meanwhile, the near-surface setting can support faster follow-up drilling and metallurgical testing.

Phosphate and uranium co-occurrence changes the project economics

Phosphate supports fertilizers and food security strategies. The Parnaiba basin also shows phosphate assays up to 260,200ppm. As a result, developers may evaluate integrated flowsheets and multi-product revenue potential.

Uranium also appears in near-surface assays up to 1,268ppm. However, uranium adds regulatory complexity and licensing time. Therefore, project design must balance by-product value with permitting discipline and community engagement.

The next step is turning geochemical anomalies into compliant mineral resources. Developers must prove continuity, tonnage, and recovery rates. Meanwhile, Brazil can position Piaui as a new node in critical minerals diversification.

The Metalnomist Commentary

This looks like a high-upside discovery because it combines heavy REE with phosphate in accessible geology. However, real value depends on metallurgy, separations, and permitting speed. The best outcome is a phased plan that de-risks uranium early.

Meteoric Brazil rare earths project faces licensing setback in Minas Gerais

Meteoric Brazil

The Meteoric Brazil rare earths project hit a regulatory wall in Caldas, Minas Gerais. Congeapa rejected mining in the APA buffer zone. The decision blocks three of four stage-one deposits. Therefore, the Meteoric Brazil rare earths project must revise its plan. Meteoric is reviewing options after the buffer-zone ruling.

Brazilian law prohibits mining inside the Pedra Branca APA and its buffer. As a result, approvals expected this year now look challenging. The Meteoric Brazil rare earths project holds a vast Caldeira resource. Company data cite 1.5bn tonnes at 2,359ppm TREO. However, location risk now outweighs headline grade.

What the ruling means and potential paths forward

The council decision targets activity within the protected buffer. Meteoric began licensing in May 2024 for a preliminary license. Timelines assumed clearance by November this year. However, the buffer ruling disrupts those targets. Options include deposit sequencing, redesigned pits, or relocation of stage-one focus. Legal appeal and stakeholder engagement also remain possible.

The Metalnomist Commentary

This decision underscores Brazilian permitting sensitivity near APAs. Expect higher ESG scrutiny, phased plans, and tighter mine design. Investors should watch alternate staging, community dialogue, and any legal remedies.

EU Brazil critical minerals agreement targets strategic autonomy

Brazil critical minerals

The EU Brazil critical minerals agreement signals a major shift in how Europe secures lithium, nickel and rare earths. The EU Brazil critical minerals agreement aims to underpin the bloc’s digital and clean transitions while reducing exposure to geopolitical shocks. By elevating Brazil as a strategic partner, the EU Brazil critical minerals agreement also diversifies away from single-country dependence in sensitive supply chains.

EU Brazil critical minerals agreement builds on Mercosur trade deal

The new framework for critical minerals cooperation comes as the EU signs a long-awaited free trade agreement with Mercosur. This broader deal creates a legal and commercial backbone for long-term investment in Brazil’s mining, processing and midstream industries. As a result, European OEMs and utilities gain clearer access to Brazilian lithium, nickel and rare earths under a stable trade regime.

EU leaders explicitly link critical minerals to the green and digital transitions, not just to raw material security. The EU wants Brazilian supply to feed battery plants, magnet producers and clean-tech manufacturers across the bloc. Meanwhile, joint projects in exploration, processing and ESG standards can lift Brazil’s role from simple ore exporter to integrated value chain partner.

The trade and minerals agenda also reflects Brazil’s own industrial policy. Brasília seeks to climb the value chain by promoting local processing, refining and technology transfer. EU financing, offtake contracts and technology cooperation can accelerate that goal and create more predictable long-term flows to European buyers.

China export controls keep rare earth risks in focus

China’s rolling export controls on medium and heavy rare earths remain the backdrop for this strategic pivot. Even with recent suspensions and simplified licensing, Beijing still holds powerful levers over global magnet and rare earth supply. European policymakers view these episodes as a warning that minerals can become tools of coercion in future disputes.

Therefore, the EU is racing to build parallel supply routes through partners like Brazil, Australia, Canada and the US. New agreements with Brazil complement EU critical raw materials partnerships already under way with other producer countries. In practice, this means more diversified sourcing of rare earths, battery metals and strategic by-products into European industry.

However, turning memorandums into molecules will take time and capital. Brazil must expand infrastructure, environmental permitting capacity and midstream processing to meet European demand. The EU, in turn, must mobilise public finance, de-risk long-term offtakes and align sustainability rules with commercial reality for miners and processors.

The Metalnomist Commentary

This deal underlines how trade policy and critical minerals strategy now move in lockstep. For metals and mining players, EU–Brazil alignment could unlock new funding, offtake and joint-venture structures over the next decade. The key question is how fast projects can move from political announcements to bankable assets before the next supply shock hits.

Brazil Critical Minerals Deals With US Highlight Rare Earths and Lithium Strategy

Brazil Critical Minerals Deals

Brazil critical minerals deals with the US are gaining momentum as Goias and Minas Gerais move to deepen cooperation on rare earths, lithium, and other strategic minerals. The two neighboring states hold some of Brazil’s most important mineral reserves and are trying to position themselves inside the global critical minerals supply chain.

Goias has signed a preliminary agreement with the US to support cooperation around rare earth reserve development. Minas Gerais is also preparing a similar agreement focused on lithium and other critical minerals.

Brazil critical minerals deals at the state level are not legally binding and do not grant exploration rights. However, they can support research, technical training, environmental licensing coordination, and tax incentives for foreign companies.

Goias and Minas Gerais Push Beyond Raw Mineral Exports

Goias is seeking to use US cooperation to improve mineral mapping, technical capability, and project development. The state wants to move beyond raw mineral exports and build stronger capacity around higher-value mineral development.

This ambition matters because Brazil has major resource potential but remains cautious about becoming only a supplier of unprocessed critical minerals. Rare earths, lithium, and other strategic materials carry far greater industrial value when linked to processing, refining, separation, and downstream manufacturing.

Minas Gerais adds another strategic layer because it holds Brazil’s largest lithium reserves. Together, Goias and Minas Gerais could become important partners for the US as Washington looks to diversify supply chains away from China-dominated critical mineral processing.

State-Level Diplomacy Pressures Brazil’s Federal Strategy

Brazil critical minerals deals with individual states also carry political weight. Goias and Minas Gerais are led by governors more aligned with the Trump administration than Brazil’s federal government, creating a possible pressure point in national trade negotiations.

President Luiz Inácio Lula da Silva has resisted any agreement that does not include commitments to develop processing and refining capacity inside Brazil. That position reflects a wider industrial policy concern: Brazil wants mineral value creation, not only mineral extraction.

The US has already signed critical minerals agreements with several Latin American countries, including lithium producers Chile, Bolivia, and Argentina, as well as copper-rich Ecuador and Peru. Brazil remains a tougher negotiator because it has the resource base, market size, and political incentive to demand more domestic value addition.

The Metalnomist Commentary

Brazil critical minerals deals show that resource diplomacy is moving from national capitals to state governments. The central question is whether Brazil can turn US interest into processing, refining, and industrial capacity rather than another raw-material export cycle.

Brazil Critical Minerals Bill Moves Country Toward Domestic Processing Strategy

Critical Minerals

Brazil critical minerals bill approval by the lower house marks a major step toward turning the country’s mineral reserves into a domestic industrial development strategy. The bill establishes the national policy of critical and strategic minerals and creates incentives for companies to process and transform those materials inside Brazil.

Brazil critical minerals bill measures include a new mineral activity guarantee fund backed by R2bn in federal money. The fund will support projects linked to the production of critical and strategic minerals.

Brazil critical minerals bill incentives also include R5bn in tax credits over five years to encourage processing and transformation. This shows that Brazil does not want to remain only an exporter of raw materials.

The bill will now move to the senate. Mines and energy minister Alexandre Silveira said he will work directly with senators to accelerate approval, framing critical minerals as a matter of economic modernisation and national sovereignty.

Processing Incentives Target Value Creation Inside Brazil

The bill creates the national council for the industrialisation of critical and strategic minerals. The council will decide which minerals qualify as critical and strategic and will update the list every four years.

This structure is important because Brazil has large resource potential but still needs stronger domestic processing capacity. Without refining, separation, transformation and recycling, mineral wealth can leave the country as low-value raw material.

The proposed guarantee fund and tax credits are designed to change that pattern. They will support projects considered strategic under the national policy, with a focus on minerals that can strengthen Brazil’s industrial base.

Congress member Arnaldo Jardim, the bill’s rapporteur, said critical minerals represent a development opportunity for Brazil. He argued that the country should become a major rare earths producer, stimulate recycling through urban mining and make its processing industry more competitive.

That message reflects a broader shift in resource policy. Brazil is trying to position critical minerals as a tool for industrial development, not only export revenue.

Rare earths are especially important. Brazil has significant rare earth potential, and global buyers are searching for alternatives to China-dominated supply chains. If Brazil can move beyond mining into separation and processing, it could become more relevant to magnet, defence, electronics and clean energy markets.

Urban mining also deserves attention. Recycling can strengthen domestic supply, reduce waste and create secondary sources of critical materials from electronics, batteries, industrial scrap and end-of-life equipment.

US Interest Raises Brazil’s Strategic Importance

The bill comes as Brazil and the US are discussing critical minerals more actively. Presidents Luiz Inacio Lula da Silva and Donald Trump are expected to meet this week, and critical minerals are likely to be part of the agenda.

The US has long sought a critical minerals agreement with Brazil. Goias state has already signed a cooperation agreement with the US, although Brazil’s federal government has challenged its legal validity.

That dispute shows how politically sensitive critical minerals have become. Foreign partnerships can bring investment and market access, but the federal government wants to ensure that strategic minerals serve national interests.

Brazil holds about 10% of global critical minerals reserves, according to domestic research and mining institutions. The sector is expected to attract $21.3bn in investment by 2030.

This gives Brazil strong leverage. The country has rare earths, niobium, graphite, nickel, lithium and other minerals that are increasingly important to batteries, magnets, aerospace, electronics and energy transition technologies.

However, reserves alone will not determine Brazil’s role. The country must build processing capacity, permitting efficiency, infrastructure, financing tools and reliable industrial partnerships.

The new policy could help unlock that pathway. If approved by the senate and implemented effectively, it could shift Brazil from a raw material supplier toward a more integrated critical minerals economy.

The Metalnomist Commentary

Brazil is making the right strategic move by linking critical minerals to processing, tax incentives and industrial policy. The real test will be execution: Brazil must convert resource potential into refining, separation, recycling and customer-ready supply before global competitors secure the next wave of investment.

REA Heavy Rare Earths Exploration Expands in the US and Brazil

Rare Earths Americas

REA heavy rare earths exploration accelerates after a $16mn funding round. The company will develop high-grade assets in the US and Brazil. REA heavy rare earths exploration targets dysprosium and terbium supply growth. Grades at Georgia’s Foothills reach 41.3% TREO with rich monazite sands. Therefore, REA heavy rare earths exploration strengthens non-China supply optionality for magnets.

Portfolio spans US monazite and Brazil ionic clays

REA controls four projects across two countries. Foothills in Georgia hosts surface monazite with Dy and Tb. Brazil adds Alpha and Constellation ionic clays in Bahia and Minas Gerais. These clays total about 1bn tonnes of mineralization. All projects also contain neodymium and praseodymium. Homer in Goiás targets carbonatites with REE and niobium potential. As a result, REA balances near-surface sands with scalable clay resources.

Strategic value for dysprosium, terbium and NdPr supply chains

Heavy rare earths enable high-coercivity NdFeB magnets. Therefore, Dy and Tb access remains strategically critical. Ionic clays can enable simpler leaching routes at scale. Meanwhile, Foothills offers high grades and quick sampling cycles. NdPr credits improve project economics. Additionally, Homer’s niobium upside diversifies revenue. Offtake, permitting, and processing partners will define timelines.

The Metalnomist Commentary

REA’s mix of monazite sands and ionic clays hedges geology and processing risk. Success will hinge on low-impurity circuits and responsible leach management. Watch pilot metallurgy and early offtake signals through 2026.

China EU Dual-Use Export Controls Raise Rare Earth Supply Risk for Europe

China EU

China EU dual-use export controls have escalated after Beijing added seven military-related European entities to its export control list. The move signals a sharper trade dispute between China and the EU and could increase uncertainty around rare earths and critical metals supply to Europe.

China EU dual-use export controls prohibit domestic exporters from supplying listed entities with controlled dual-use goods, technologies and services. Overseas organisations and individuals are also barred from transferring Chinese-origin dual-use items to those entities.

China EU dual-use export controls are significant because rare earths, tungsten, antimony, germanium and gallium have all gained stronger military and strategic relevance. Many of these materials are already covered by China’s dual-use export control framework.

The targeted entities include defence, aerospace and military-linked companies in Europe. Beijing said the companies had engaged in arms sales to Taiwan or had links with Taiwan-related activity.

Rare Earths and Critical Metals Become Trade Policy Tools

China’s decision marks the first time Beijing has imposed dual-use export restrictions specifically targeting EU entities. It shows that critical materials policy is increasingly being used as a geopolitical instrument.

The move follows growing friction between China and the EU, including disputes around cybersecurity rules and alleged discriminatory treatment of Chinese companies. Beijing has warned that it could take broader countermeasures if Chinese firms continue to face restrictions.

This matters for Europe because the region remains a major buyer of Chinese rare earths and critical minerals. The Netherlands, Italy, France and Spain all received rare earth shipments from China in the first quarter.

Rare earths are essential for permanent magnets, electric motors, wind turbines, robotics, defence systems, aerospace components and precision electronics. Heavy rare earths such as dysprosium and terbium are especially important for high-performance magnets used in demanding operating environments.

Other controlled critical metals also carry strategic weight. Tungsten is used in hard metals, defence systems and high-temperature applications. Antimony supports flame retardants, ammunition and alloys. Germanium and gallium are critical for semiconductors, optics, satellites and power electronics.

China’s use of export controls has become more systematic. Beijing has already tightened critical minerals exports to Japan this year, which disrupted shipments of dysprosium and terbium and forced buyers to seek alternative supply.

Europe Faces Higher Security Premiums for Heavy Rare Earths

Europe’s immediate risk is not a full loss of Chinese supply. The more likely impact is higher compliance risk, licensing uncertainty and greater pressure on buyers that need controlled materials for defence, aerospace and advanced manufacturing.

This could widen the security premium for non-China rare earths and minor metals. Buyers without reliable export licences may need to pay more for material available in the Atlantic market.

Heavy rare earth prices outside China have already surged because of tight availability and stronger Japanese buying. Yttrium oxide prices in Europe have climbed sharply this year, reflecting the scarcity of prompt non-China supply.

If EU-China tensions continue, European buyers may accelerate efforts to diversify supply. That could benefit projects in Australia, Brazil, Estonia, the US and other jurisdictions trying to build rare earth separation, metal-making and magnet capacity outside China.

However, diversification will not be quick. Rare earth supply chains require mining, separation, refining, metal conversion, alloying and magnet manufacturing. Each stage needs qualification, capital and technical expertise.

For European manufacturers, the policy signal is clear. Critical metals procurement can no longer rely only on price and delivery time. Buyers must now evaluate origin risk, licensing exposure, dual-use classification and strategic inventory needs.

The broader market implication is that China’s critical minerals controls are becoming a routine part of trade policy. Europe must now treat rare earths and minor metals as supply-chain security issues, not just raw material inputs.

The Metalnomist Commentary

China’s latest export control move shows that rare earths and minor metals are becoming geopolitical leverage points. Europe’s challenge is no longer just finding alternative supply, but building a complete industrial chain that can survive licensing shocks.

Aclara heavy rare earths funding advances Carina project in Brazil

Aclara Resources

Aclara heavy rare earths funding will accelerate the Carina project in Brazil. Aclara heavy rare earths funding comes from the US DFC, totaling up to $5mn. Aclara heavy rare earths funding targets the feasibility study now underway.

What the DFC funding enables

The new capital supports a feasibility study launched in July 2025. The study is due by the end of the first quarter of 2026. The DFC is a US government development finance agency. The instrument can convert into equity under set conditions. Conversion triggers include a single $50mn+ round or $75mn across rounds within 12 months. The path anticipates construction finance for Carina.

Why this matters for US-aligned supply chains

Aclara runs a vertically integrated rare earth model across Brazil and Chile. The company plans a US separation facility for mixed carbonates into oxides. It also partners with Chile’s CAP to produce rare earth metals and alloys. The package supports heavy rare earths outside China and diversifies supply. The study will define scale, flowsheet, costs, and ESG performance.

The initiative strengthens strategic cooperation between North and South America. It aligns with efforts to localize midstream and metal production. It also positions Aclara to pursue offtakes with magnet supply chains.

The Metalnomist Commentary

DFC participation de-risks early studies and signals policy support for heavy rare earths. Watch the equity conversion triggers and downstream US separation timing. Execution will hinge on permitting, capex discipline, and securing long-lead equipment.
