St George Sends Signal Sample to Brazil’s Magnet Ambitions

Jul 29, 2025

Highlights

  • St George Mining becomes a first mover in Brazil's rare earth downstream industrialization by delivering a 30 kg rare earth oxalate sample to MagBras.
  • Araxรก Project boasts a high-grade JORC resource of 40.64 Mt @ 4.13% TREO in Minas Gerais state.
  • Despite a promising geopolitical backdrop, the project remains pre-development with no commercial-scale production yet confirmed.

Australian-listed St George Mining (opens in a new tab) (ASX: SGQ) just made the first delivery of processed rare earths to MagBras, Brazilโ€™s flagship public-private magnet supply chain project. The sampleโ€”30 kg of rare earth oxalateโ€”comes from its Araxรก Project, a large carbonatite-hosted deposit in Brazilโ€™s Minas Gerais state, boasting a JORC resource of 40.64 Mt @ 4.13% TREO.

This makes St George the first mover in Brazilโ€™s rare earth downstream industrialization. With backing from SENAI, FIEMG, and participation from Stellantis (opens in a new tab) and Iveco, MagBras aims to be Latin Americaโ€™s first permanent magnet production hub.

What Checks Out

  • Resource quality and grade: The Araxรก deposit is genuinely high-grade. Carbonatites like Mt Weld and Mountain Pass are proven winners, and St Georgeโ€™s 2025 resource estimate places Araxรก firmly in the same league. But economically, it's premature to compare. Mt Weld and MP--both are operating mines with full infrastructure and separation capabilities. Araxรก is still in pre-feasibility.
  • Geopolitical backdrop: References to rising U.S. interest in Brazilโ€™s niobium and rare earths are accurate. The Pentagonโ€™s price floor with MP Materials ($110/kg NdPr) and Appleโ€™s downstream deal reinforce this shift.
  • Drilling momentum: A five-rig, 9,000+ meter campaign to upgrade the resource is in motionโ€”a bullish sign.

Whatโ€™s Still Developing

  • The sample isnโ€™t newly produced: The oxalate delivered to MagBras comes from pilot plant work done over a decade ago (pre-St George ownership). Thatโ€™s fine for R&D, but itโ€™s not representative of current flowsheet performance.
  • Downstream reality check: Thereโ€™s no indication MagBras is near commercial-scale magnet production. R&D is just thatโ€”experimental.
  • No offtake yet: St George has a Memorandum of Understanding with MagBras, but no firm sales, volumes, or contracts.

Strategic Hype or Substance?

The release frames Araxรก as โ€œworld-class,โ€ and the tone suggests commercial maturity. But no feasibility study, no capex plan, no metallurgy update, and no downstream facility online means this is still pre-development optimism, not production reality.

Verdict: A Symbolic First Stepโ€”But Still a Lab Sample

St George has strong rocks and good timing. But Brazilโ€™s downstream magnet dreams remain early-stage. Investors should applaud the milestoneโ€”but is it wise to price in a magnet supply chain until the drills, flow sheets, and factories catch up?
