Highlights

• Viridis Mining pursues U.S. and European off-take agreements with floor pricing for its $360M Colossus rare earths project in Brazil, targeting 2028 production.
• Floor pricing mechanisms are critical financing tools to secure debt and protect against China's pricing influence in the permanent magnet market.
• Despite Brazil's second-largest reserves and EU political support, commercial success hinges on developing processing capacity and securing bankable long-term contracts.

A report (opens in a new tab) by Sharecafe Australia says Viridis Mining and Minerals Ltd (opens in a new tab) is in active talks with potential U.S. and European off-takers for rare earth material from its Colossus project in Minas Gerais, Brazil. The move fits neatly into a familiar Western narrative—diversify away from China—but the commercial mechanics deserve closer inspection.

The Real Signal: Pricing Power, Not Just Buyers

According to Viridis Brazil country manager Klaus Petersen (opens in a new tab), negotiations center on multiple off-take agreements with refiners and magnet manufacturers, coupled with a minimum floor price for production from the roughly US$360 million project. That detail matters. Floor pricing is not a marketing flourish; it is a financing tool. Junior developers increasingly need price protection to secure debt and equity in a market where China—responsible for roughly 90% of global rare earth permanent magnet output—can influence downstream pricing.

This is commercially rational. It is also aspirational.

Brazil’s Promise—and Its Constraint

The article correctly notes that Brazil holds the world’s second-largest rare earth reserves after China. That fact is well-established. What remains underdeveloped is commercial-scale production and downstream processing. Minas Gerais is geologically prospective, but Brazil still lacks separation capacity, magnet manufacturing, and a mature regulatory playbook for rare earths. Off-take agreements alone do not solve those gaps.

Europe’s Interest, Not Europe’s Infrastructure

The Sharecafe piece references political momentum between Brazil and the European Commission, including statements by Ursula von der Leyen about cooperation on lithium, nickel, and rare earths. That context is accurate. What is missing is Europe’s own bottleneck: processing and magnet capacity remain thin, meaning many “European” off-takers still route material through Asia.

What’s Speculative—and What Isn’t

Solid:

• Western buyers are actively seeking non-Chinese supply.
• Floor pricing is increasingly demanded by financiers.
• Viridis targeting a 2028 production start aligns with typical project timelines.

Speculative:

• That off-take agreements alone will insulate Viridis from China-linked price pressure.
• That Brazil-EU political alignment translates quickly into bankable contracts.
• That magnet makers will commit long-term without downstream certainty.

REEx Take

Viridis is doing what juniors must do: talk early, talk broadly, and talk price floors. The strategy is credible. The execution risk remains high. Until Brazil builds real processing capacity and Western buyers commit to volume—not just intent—off-take discussions are necessary but not sufficient.
