Highlights

• Southern Alliance Mining signs a collaboration agreement with Brazilian Critical Minerals to jointly develop the massive 1-billion-tonne Ema Project using in-situ recovery (ISR) technology.
• SAM is positioning itself as a global ISR rare earth operator-exporter, leveraging its proven Malaysian Gerik project success with over 20,000 tonnes of production.
• The partnership signals SAM's strategic push to build a cross-continental ISR platform linking Southeast Asian expertise with South American scale outside China's ecosystem.

Southern Alliance MiningLtd. (opens in a new tab) (SAM) has signed a non-binding collaboration agreement with Brazilian Critical Minerals (BCM), signaling a strategic push beyond Malaysia into a broader in-situ recovery (ISR)-driven rare earth supply network. At face value, the deal centers on evaluating joint development and potential offtake from BCM’s Ema Project (opens in a new tab) in Brazil—an enormous ~1 billion tonne ionic adsorption clay (IAC) deposit being advanced toward in-situ recovery (ISR) production. But the deeper implication is more strategic: SAM is positioning itself as an operator-exporter of ISR rare earth know-how, not just a regional producer.

As Rare Earth Exchanges has reported in articles such as “_SAM is the Place to be_…” the Malaysian operation brings credibility. Its Gerik project in Malaysia has already produced over 20,000 tonnes of mixed rare earth carbonate, demonstrating commercial ISR viability in a difficult pricing environment. BCM brings scale. Together, they are testing whether ISR can be replicated globally across clay-hosted deposits.

What is SAM really up to?

This is an early-stage move toward building a cross-continental ISR platform—linking Southeast Asian production expertise with South American resource scale. The explicit focus on “offtake” and “distribution” suggests SAM is also probing downstream positioning, potentially seeking to secure buyers or intermediated market channels outside China.

Bottom line: It would appear SAM is not just trying to diversify—it is quietly attempting to become a repeatable ISR developer and commercial bridge in the emerging ex-China rare earth ecosystem.
