St George Signs MoU with Técnicas Reunidas for Araxá Rare Earths

Why It Matters

The deal brings St George closer to a non‑China supply chain for rare‑earths, a strategic advantage as Europe and the U.S. seek secure critical‑material sources. Successful processing could unlock significant revenue and strengthen the company’s position in the global REE market.

Key Takeaways

• St George partners with Técnicas Reunidas for Araxá REE processing tests
• RARETECH will produce mixed carbonates and oxides from Brazilian samples
• Agreement may lead to full‑scale plant design for European market entry
• Araxá is South America’s largest hard‑rock rare‑earth deposit
• Partnership expands St George’s downstream capabilities beyond Brazil

Pulse Analysis

The rare‑earth market remains heavily weighted toward China, which supplies over 80 % of global output. Governments and manufacturers in the United States and Europe are therefore accelerating projects that can diversify the supply chain. Brazil’s Araxá deposit, owned by St George Mining, is the continent’s largest hard‑rock source of neodymium, dysprosium and other critical elements, making it a strategic asset for any downstream venture. Turning the raw ore into market‑ready carbonates and oxides is the missing link that could shift the balance of power in the sector.

The memorandum of understanding with Spain’s Técnicas Reunidas brings the company’s proprietary RARETECH platform to the test phase. RARETECH is designed to extract and fractionate rare‑earth elements, delivering mixed carbonates and high‑purity oxides in a single flow‑through process. By applying this technology to Araxá samples, St George hopes to validate an optimal processing route that minimizes waste and energy consumption. The MoU also covers engineering services such as flow‑diagram design and feasibility studies for a future commercial plant, echoing the firm’s recent collaborations in the United States and Japan.

If the pilot work confirms commercial viability, St George could fast‑track a processing facility that feeds directly into European battery and wind‑turbine manufacturers. The partnership aligns with the EU’s critical raw‑materials action plan, which incentivizes projects that reduce reliance on Chinese imports. For investors, the deal signals a tangible step toward monetizing Araxá’s estimated 1.5 million tonnes of rare‑earth oxide equivalents, potentially unlocking multi‑billion‑dollar revenue streams. In the broader context, the collaboration illustrates how mining firms are leveraging specialized engineering expertise to close the gap between resource extraction and end‑use markets.
