Viridis Mining Pitches Brazil's Colossus Project as Europe's Alternative to Chinese Rare Earths

Key Takeaways 80% confidence

• Viridis Mining and Minerals' managing director Rafael Moreno says ending China's rare-earths dominance is "paramount," positioning the company's Colossus project in Minas Gerais, Brazil as a Western-aligned alternative supplier.
• Colossus hosts 493 million tonnes of ionic-adsorption-clay ore at 2,508 parts per million total rare-earth oxide -- which Viridis calls the largest undeveloped deposit of its kind outside China -- with grades it says run four to six times higher than typical Chinese ionic-clay operations.
• The EU's Commissioner for International Partnerships, Jozef Síkela, toured Viridis's Poços de Caldas demonstration plant in June 2026, one of four Brazilian projects the EU has named for closer critical-minerals cooperation.
• Viridis holds a non-binding letter of intent with Belgian chemicals group Solvay to separate Colossus's mixed rare-earth carbonate into individual oxides, plus a conditional letter of support from Export Finance Australia toward a debt facility of up to A$77 million.
• The company is targeting first production in the first half of 2028 against an estimated $360-370 million capital cost, while China still holds roughly 90% of global rare-earth refining capacity.

Australian miner Viridis Mining is positioning Brazil's Colossus rare-earth project as a non-Chinese EU supplier, after an EU commissioner's visit and a Solvay letter of intent, targeting first production in 2028.

Analysis 75% confidence

Most of the world's rare-earth deposits sit in hard rock, which means blasting, crushing and acid leaching before any usable oxide comes out the other end. Colossus doesn't work that way. Viridis Mining and Minerals' project in Minas Gerais is an ionic-adsorption-clay deposit -- the same geology China has used for decades to dominate the heavy rare earths used in permanent magnets -- and its ore can be leached with a mild reagent rather than blasted or roasted. That distinction is why Viridis describes Colossus, at 493 million tonnes grading 2,508 parts per million total rare-earth oxide, as the largest undeveloped deposit of its kind outside China, and why the company says its grades run four to six times higher than typical Chinese ionic-clay operations. A demonstration plant at Poços de Caldas, commissioned in May 2026, is already producing mixed rare-earth carbonate from surface ore at a rate of up to 100 kilograms an hour -- a proof of concept, not yet a mine.

That proof of concept was enough to draw a European commissioner to rural Brazil. Jozef Síkela, the EU's Commissioner for International Partnerships, toured the Poços de Caldas plant in June 2026 with officials from the European Investment Bank and the EU's Delegation to Brazil, one stop in a broader push that has named Colossus among four Brazilian projects under active EU investment review. The timing matters. The EU's own Critical Raw Materials Act has designated 47 strategic projects, only three of them for rare-earth processing, and the European Court of Auditors concluded in February 2026 that roughly 40% of those 47 carry no documented financing and that none will reach processing scale before 2028. Brussels doesn't have a domestic rare-earth pipeline it can lean on yet, which is why a commissioner showing up in person at a foreign junior miner's demonstration plant reads as more than a courtesy call -- it signals the EU shopping outside its own strategic-projects list for capacity it cannot build fast enough at home.

Viridis is pairing that political interest with an actual industrial partner. The company holds a non-binding letter of intent with Solvay, the Brussels-based chemicals group that is one of the few in Europe with commercial rare-earth separation capability, covering potential offtake and technical collaboration on turning Colossus's carbonate into separated neodymium and praseodymium oxides. On financing, Export Finance Australia has issued a non-binding, conditional letter of support pointing toward a direct-lending facility of up to A$77 million, against an estimated $360-370 million capital cost for a commercial-scale plant that could rise to $400 million once working capital is included. None of that is committed capital yet. But it is the scaffolding -- an offtake counterparty with real separation chemistry, a government-backed lender circling, and a construction target of first production in the first half of 2028, ramping to steady-state by the end of that year -- that Moreno is pointing to when he calls it paramount to end China's grip on a supply chain running through cars, wind turbines and military jets.

None of this changes the supply picture today. China still accounts for an estimated 90% of global rare-earth refining and separation capacity against roughly 60% of mine production, the same imbalance that let Beijing's April 2025 export-licensing rules ripple through automakers within weeks. Colossus, even on Viridis's own schedule, is at least two years from its first tonne of saleable carbonate, and Moreno's target of capturing 5% of the world's magnet rare-earths market is a company ambition, not a booked contract. What sets this story apart from the diplomatic declarations and processing statistics already in circulation this month is specificity: a named deposit, a named separation partner, a dated financing target and a commissioner's travel schedule. For India, which imports most of the rare-earth magnets its EV and electronics manufacturers use and has no large-scale separation capacity of its own either, Colossus previews the kind of project -- an ionic-clay deposit, a Western offtake partner, a government-backed loan -- that any non-Chinese magnet supply chain will eventually have to resemble, wherever in the world it gets built.

Why This Matters 70% confidence

MetalsCost has already tracked China's roughly 90% grip on rare-earth refining through this month's BRICS declaration and Latin America investment coverage; what Colossus adds is a specific, dated project a Western buyer could actually contract with. The EU's own Critical Raw Materials Act has designated 47 strategic projects, but the European Court of Auditors found in February 2026 that none will reach processing scale before 2028 and that 40% lack documented financing -- precisely the gap a commissioner-level visit to a foreign junior miner is meant to help close. For Indian manufacturers who import most of their rare-earth magnets and have no large-scale separation capacity of their own, Colossus is an early test case for what a genuinely diversified, non-Chinese magnet supply chain would have to look like in practice.

Price Impact

Colossus is a pre-construction project targeting first production no earlier than the first half of 2028; nothing in the EU's June 2026 visit or the Solvay letter of intent changes rare-earth supply or demand today, keeping the near-term price impact on neodymium and praseodymium neutral even as the project firms up the medium-term case for non-Chinese magnet supply.

Fundamental Analysis

Demand Drivers 68% confidence

Moreno frames Colossus's output around magnets for cars, wind turbines and military jets; Viridis separately targets European carmakers and wind-turbine manufacturers as the eventual buyers for its neodymium and praseodymium oxides.

Supply Drivers 74% confidence

China's April 2025 licensing controls on seven heavy rare-earth elements are the immediate backdrop; Viridis is positioning Colossus's 493-million-tonne ionic-clay deposit, with grades it says run four to six times higher than typical Chinese ionic-clay operations, as a non-Chinese alternative supply source.

Government Policies 72% confidence

The EU's Critical Raw Materials Act has designated 47 strategic projects (only three for rare-earth processing) and adopted the RESourceEU action plan in December 2025 to coordinate joint purchasing and stockpiling; separately, the EU and Brazil are negotiating a critical-minerals political agreement covering lithium, nickel and rare earths, with Colossus named one of four priority Brazilian projects.

Geopolitical Risks 70% confidence

China's roughly 90% share of global rare-earth refining gives it leverage over defense-linked manufacturing -- Moreno cites military jets specifically -- the same dynamic behind the European price spikes that followed Beijing's April 2025 export-licensing round.

Mining Production 74% confidence

Colossus hosts 493 million tonnes of ionic-adsorption-clay ore at 2,508 parts per million total rare-earth oxide, which Viridis calls the world's largest undeveloped deposit of its kind outside China; the company had an Installation Licence application pending as of May 2026 and targets first production in the first half of 2028.

Refinery Output 70% confidence

Viridis's demonstration plant at Poços de Caldas processes up to 100 kilograms of ore an hour into mixed rare-earth carbonate; a non-binding letter of intent with Solvay, one of Europe's few companies with commercial rare-earth separation capacity, would handle the downstream split into individual oxides.

Market Sentiment

Alternative Scenarios 60% confidence

• If Viridis converts its Solvay letter of intent into a binding offtake agreement and secures Export Finance Australia financing on schedule, Colossus could become one of the first commercial non-Chinese sources of separated neodymium and praseodymium for European buyers by the end of the decade.
• If the EU's own Critical Raw Materials Act projects and its Brazil partnership remain as underfunded as the European Court of Auditors described in February 2026, Colossus's output may end up competing for the same limited pool of Western financing as other pre-construction rare-earth projects worldwide, slowing its own timeline as well.

Who Benefits, Who Loses

Investor Watchlist 70% confidence

Educational items to monitor — not investment advice.

• Whether Viridis converts its non-binding Solvay letter of intent into a binding offtake agreement
• Progress on Viridis's Installation Licence application for Colossus, submitted in May 2026
• Whether Export Finance Australia converts its conditional letter of support into a committed debt facility
• Any EU Critical Raw Materials Act strategic-project designation naming Colossus specifically
• Viridis's progress toward its targeted first-half-2028 first production date

Price Risks 62% confidence

• A slower-than-planned Colossus timeline would leave China's roughly 90% refining share unchallenged for longer, keeping near-term magnet-rare-earth pricing power concentrated in Beijing's export-licensing decisions.
• Any further tightening of China's rare-earth export rules remains a bigger near-term lever on neodymium and praseodymium prices than a single pre-construction Brazilian project.

Historical Comparison

China's April 2025 rare-earth export-licensing round: European dysprosium prices reportedly rose to roughly six times their Chinese domestic equivalent after Beijing's first 2025 licensing round -- the same supply concentration Viridis is positioning Colossus to help ease for European buyers.
