Quick answer

Minas Gerais can become part of Europe’s China alternative in critical minerals, but geology alone will not create that alternative.

The test is whether Brazil can connect rare earth resources with processing, Western offtake, financing, technology transfer, environmental credibility and social licence.

The current focal point is Viridis Mining and Minerals in Poços de Caldas, Minas Gerais. The company is developing the Colossus rare earth project, has opened a research and processing centre, and is positioning mixed rare earth carbonate supply toward US and European buyers rather than Chinese offtake.

Core market reading:

Brazil is becoming strategically visible because Europe is looking for non-China supply chains. That requires processing capacity, reliable offtake, finance, technology and local legitimacy.

The Signal From Poços de Caldas

The latest signal came from Poços de Caldas in Minas Gerais. EU Commissioner for International Partnerships Jozef Síkela visited Viridis Mining and Minerals’ rare earth centre and framed Brazil as a strategic partner for Europe’s critical-minerals security.

That visit matters because it shifts Brazil’s role from resource geography to supply-chain diplomacy. Europe is mapping projects that can help reduce dependence on Chinese-controlled refining and magnet-related value chains.

Viridis is the visible test case. Reuters reported that the company is planning a commercial plant of around US$360 million, designed to produce 15,000 tonnes of mixed rare earth carbonate per year from 2028. The company has also discussed a broader partnership with Solvay, including a possible supply structure.

This gives the story a concrete geography: Poços de Caldas, Minas Gerais. It also gives the story a concrete industrial question: can Brazilian rare earth material become part of a Western value chain before it is absorbed into the existing China-centered system?

"Minas Gerais is a test of whether Europe can build a non-China supply chain beyond the mine gate."

The China Problem Is Processing Power

The critical-minerals debate is often framed as a race for deposits. That is too shallow for rare earths.

Reuters put the imbalance in plain numbers: China accounts for about 60 percent of global rare earth mine production and 90 percent or more of refined rare earth production. In another Reuters report on Serra Verde, China is described as accounting for about 90 percent of global processed rare earth output.

That is why the strategic question is not only where rare earths are mined. The deeper question is where they are separated, refined and turned into magnet materials.

China’s strategic position is strongest in the middle and downstream layers: separation, refining, metals, alloys and magnet manufacturing. That is where ore becomes usable industrial power.

This is why a Brazilian rare earth deposit does not automatically solve Europe’s supply-chain problem. Mixed rare earth carbonate is a meaningful intermediate product, but it is not a finished magnet supply chain. It still has to be separated, refined and moved into metals, alloys and component production.

Europe’s problem is therefore not a missing map of minerals. The problem is the missing industrial middle between geology and finished components.

01 Geology Brazil has deposits that are now strategically visible to Europe and the United States.
02 Mining Projects must move from resource claims into executable mine plans and permits.
03 MREC Mixed rare earth carbonate can become the first tradable intermediate product.
04 Separation Refining and separation decide whether Brazil feeds Western value chains or existing Asian capacity.
05 Magnets The strategic endpoint is industrial use: EVs, wind turbines, defence, robotics and electronics.

Minas Gerais as the Test Case

Minas Gerais is not new to mining. That is precisely why the rare earth question there is so interesting.

The state has mining expertise, industrial services, logistics knowledge and a long history of metallurgical depth. It also has a heavy social and environmental memory from mining disasters and upstream tailings-dam failures in Mariana and Brumadinho.

That combination makes Minas Gerais both attractive and difficult. It can host sophisticated mineral projects, but new mining claims cannot rely on resource enthusiasm alone. They have to clear a higher credibility threshold.

Viridis’ Colossus project is therefore a useful test. If the company can move from research and pilot processing into bankable commercial output, Western offtake and credible environmental performance, Minas Gerais becomes more than a location. It becomes a proof point for Brazil’s critical-minerals strategy.

The key distinction is that Poços de Caldas is not a generic mining headline. It is a processing and supply-chain headline. The project matters because Europe needs a product flow that can connect to separation and magnet systems outside China.

Strong signal: concrete project, concrete geography

Viridis gives the EU a specific Brazil project in Minas Gerais rather than a broad statement about Latin American resource potential.

Watch signal: MREC is still an intermediate product

Mixed rare earth carbonate is strategically useful, but Europe still needs separation, refining, alloy and magnet capacity to reduce China exposure.

Risk signal: social licence cannot be assumed

Minas Gerais has mining depth and mining trauma. Critical-minerals projects must show governance and environmental credibility early.

Brazil’s Stronger Hand

Brazil is entering the critical-minerals conversation with a stronger hand than in previous commodity cycles.

The country does not want to be treated simply as a raw-material source. The political message from Brasília is increasingly clear: extraction must be linked to local value creation, processing, jobs, technology and industrial capability.

This is why the EU-Brazil conversation is important. It is not only an offtake discussion. It is a negotiation over where value is created.

Europe wants diversification from China. Brazil wants to avoid another cycle in which it exports raw materials and imports the higher-value industrial outcome. The intersection of those two interests is the strategic opening.

Brazil’s leverage:

Europe needs reliable non-China supply. Brazil can offer resources, but it will increasingly ask for processing, technology, financing, skills and industrial development in return.

That is why Minas Gerais matters beyond rare earth geology. It is a place where mining services, metallurgy, industrial labour, power supply, permits, social licence and export logistics meet. If Brazil wants to move up the critical-minerals chain, Minas Gerais is one of the obvious places to try.

Europe’s Weak Spot

Europe’s weakness is implementation speed.

The Critical Raw Materials Act sets clear 2030 benchmarks: 10 percent extraction, 40 percent processing, 25 percent recycling and a maximum 65 percent dependency on any single third country for strategic raw materials. These targets explain why Brazil is now more visible in European raw-material diplomacy.

But the targets also expose the gap. The European Court of Auditors warned in 2026 that EU diversification efforts have not yet delivered meaningful results. Strategic partnerships exist on paper, but imports from several partner countries have not increased as expected, and European processing capacity remains fragile.

That is the uncomfortable context for Minas Gerais. Europe needs Brazil, but Europe also needs to become a more serious industrial buyer, lender and processing partner.

European need Brazilian opportunity Reality check
Diversify away from China concentration Brazil offers rare earth resources, lithium, nickel, niobium and a stronger political value-add agenda. Alternative supply chains require long-term offtake and financing, not only diplomatic visits.
Increase processing capacity Viridis can supply MREC, and Brazil wants more local processing. MREC must connect to separation and magnet production to become a strategic chain.
Secure sustainable sources Brazil can position projects under environmental, social and local-development claims. Mining memory in Minas Gerais makes social licence a hard condition.
Build resilient industrial inputs Brazil can become a South Atlantic node for Western critical-minerals supply. China still has scale, price power and downstream depth.

The Missing Middle: Refining and Magnets

The strategic middle of the rare earth chain is separation and magnet manufacturing.

Solvay matters here because La Rochelle is one of Europe’s most important rare earth processing references. Reuters reported in 2024 that Solvay aimed to supply 30 percent of European demand for critical magnet components for electric vehicles and wind turbines by 2030.

That makes a Viridis-Solvay relationship strategically interesting. Brazil could supply an intermediate product. Europe could provide processing and market access. The value-chain question is whether that connection becomes a real industrial route or remains a memorandum-level ambition.

Serra Verde adds an important contrast. It is not a Minas Gerais case; it is based in Goiás. But it shows how fast Brazil’s rare earth relevance can be locked into a non-European strategic chain. Reuters reported that USA Rare Earth agreed to acquire Serra Verde in a US$2.8 billion deal and that Serra Verde’s output is covered by a 15-year supply agreement for 100 percent of production with a special purpose vehicle capitalised by U.S. government and private sources.

That sharpens the European problem. Brazil’s most advanced rare earth producer is already being pulled into a U.S.-backed mine-to-magnet strategy. Europe is therefore arriving at a more difficult stage: it has to build value-chain relationships around projects such as Viridis before the best non-China assets are already committed elsewhere.

Mining Brazil can offer geology and project geography across several critical minerals.
Processing The hard strategic question is whether intermediates become separated, refined and qualified supply.
Magnets EVs, wind turbines, defence and robotics depend on the downstream layer where China remains strongest.

Social Licence in Minas Gerais

Minas Gerais gives Brazil credibility as a mining state. It also gives every new mining project a reputational burden.

Mariana and Brumadinho changed the social and regulatory context for mining in Brazil. Tailings safety, water use, community trust, emergency planning and environmental oversight are now part of the investment story.

Critical minerals do not escape that history because they serve the energy transition. A mineral used in electric vehicles or wind turbines still needs credible extraction, processing and waste management.

This is the strongest counterargument to a simple “Europe will build an alternative in Brazil” narrative. Western buyers want lower China exposure, but they also want social, environmental and governance credibility. Brazil can offer strategic geography, yet Minas Gerais has to earn trust project by project.

Reality check

Critical-minerals diplomacy cannot bypass local mining memory.

If Europe wants Brazilian rare earths as a cleaner strategic alternative, the chain has to be credible at the mine, processing site, community level and buyer level.

Three Scenarios for the Brazil-Europe Critical Minerals Chain

The Minas Gerais story should be read through scenarios rather than a single yes-or-no answer.

Scenario What happens Strategic meaning
Extraction bridge Brazil supplies intermediate rare earth products, but separation and higher-value steps remain elsewhere. Useful diversification, limited industrial upgrading.
Processing partnership Viridis, Solvay or similar actors connect Brazil-based output with European separation and long-term offtake. A credible non-China corridor begins to form.
Industrial platform Brazil captures more local processing, technical skills, services, environmental systems and higher-value inputs. Brazil becomes a strategic minerals partner rather than a raw-material appendix.

The second scenario is the most realistic near-term goal. Brazil becomes a trusted source of intermediate products, while European and allied processing capacity grows around it.

The third scenario is Brazil’s stronger political ambition. It is also harder. It requires capital, permits, engineers, downstream demand, power reliability, environmental discipline and the ability to compete with China’s established scale.

What Companies Should Watch

For mining suppliers, processing technology firms, environmental-service providers, industrial buyers, battery-chain companies and European B2B firms, this is a market-entry and supplier-positioning story.

The opportunity sits in the implementation layer: ore characterisation, separation technology, water treatment, tailings systems, monitoring, laboratory services, ESG verification, automation, process engineering, logistics, certification and buyer qualification.

That is where Europe can add value if it wants a real Brazil partnership. Buying material is the end of the chain. Building the chain requires technology and services.

Market questions to test
  • Can Viridis convert the Colossus project from pilot and research centre into bankable commercial production?
  • Will Solvay or another Western processor turn Brazilian MREC into a qualified non-China supply route?
  • Are European buyers willing to sign offtake contracts that pay for resilience rather than only lowest-cost supply?
  • Can Brazil keep enough value locally without slowing project execution?
  • Can Minas Gerais clear the social-licence bar after Mariana and Brumadinho?
  • Will EU critical raw materials policy become financing and procurement discipline, not only strategic language?
  • Where can European suppliers enter the chain before procurement routines are locked in?

The Econosur Reading

Brazil’s critical minerals question is not whether the country has resources. It does.

The question is whether resources can become a trusted industrial route for Western buyers.

Minas Gerais is the right place to watch because it combines mining history, industrial capability, rare earth potential and social-licence pressure in one geography.

For Europe, the lesson is clear: Brazil can help reduce China exposure only if Europe brings more than diplomatic interest. It must bring financing, offtake, processing partnerships, technical capability and patience.

For Brazil, the lesson is equally clear: critical minerals give the country leverage, but leverage becomes durable only when geology turns into qualified products, credible governance and industrial value creation.

"Minas Gerais can become part of Europe’s China alternative. But the alternative is not a mine. It is a chain."

From rare earth geology to supply-chain reality

Brazil’s critical-minerals opportunity depends on more than deposits. The decisive questions are processing, offtake, financing, technology transfer, environmental credibility and whether Europe can help build a chain rather than simply buy minerals.

FAQ

Can Minas Gerais become Europe’s China alternative in critical minerals?

Minas Gerais can become part of Europe’s non-China critical minerals strategy, especially through rare earth projects such as Viridis in Poços de Caldas. Geology alone is not enough. The test is whether Brazil can connect mining, processing, Western offtake, financing, technology transfer and social licence.

Why does Europe care about Brazilian rare earths?

Europe wants to reduce dependence on concentrated critical minerals supply chains, especially where China dominates refining and magnet-related value chains. Brazilian rare earth projects give Europe a possible partner outside Asia, with a stronger local-processing argument than simple raw material exports.

What is the Viridis project in Minas Gerais?

Viridis Mining and Minerals is developing the Colossus rare earth project around Poços de Caldas in Minas Gerais. The company has opened a research and processing centre and has discussed a commercial plant that could produce mixed rare earth carbonate from 2028.

Why is processing more important than mining in rare earths?

Rare earth supply-chain power sits heavily in separation, refining, metals, alloys and magnet production. A mine or mixed carbonate output is only one step. Europe’s China alternative requires downstream processing and reliable buyers, more than a new source of ore.

What does Serra Verde change in the Brazil-Europe story?

Serra Verde shows that Brazil can produce strategically relevant rare earths at scale, but its acquisition by USA Rare Earth and the associated long-term offtake structure also show that advanced Brazilian assets can quickly become tied to US-backed supply-chain strategies.

What could block Brazil’s critical minerals opportunity?

The main risks are financing, processing capability, project execution, permitting, environmental trust, tailings and water concerns, European offtake discipline and whether Western buyers are willing to pay for supply-chain resilience instead of relying on cheaper established Chinese-linked supply chains.
