St George Sets the Stage for Araxá Growth with High-Grade REE and Niobium Hits

Why It Matters

The new drill results boost confidence in Araxá’s ability to become a world‑scale source of magnet rare earths and niobium, strengthening supply security for high‑tech and clean‑energy markets. Continued expansion could accelerate the project’s path to a feasibility study and eventual production.

Key Takeaways

• 43 m from surface grading 8.02% TREO and 0.74% Nb₂O₅.
• Total drilling reached 13,700 m in the latest campaign.
• Measured resource grew 75% to 70.91 Mt at 4.06% TREO.
• Step‑out hole AXDD107 delivered 100 m thick, 5.65% TREO intercept.
• Expansion drilling suggests Araxá mineralisation limit not yet reached.

Pulse Analysis

St George’s latest drilling campaign at Araxá underscores the project's emerging status as a high‑grade source of both rare earth elements and niobium. Intercepts such as 43 metres grading 8.02% TREO and 0.74% Nb₂O₅ from surface, alongside multiple 30‑plus metre zones exceeding 4% TREO, illustrate a consistent mineralised envelope. The breadth of these results, captured across 13 holes and over 13,700 metres of core, demonstrates the continuity of the carbonatite system and its potential to deliver bulk volumes of magnet‑critical materials.

Resource estimates have been dramatically revised, with the measured‑and‑indicated component expanding 75% to 70.91 million tonnes at 4.06% TREO and 0.62% Nb₂O₅. The step‑out drilling, exemplified by a 100‑metre thick, 5.65% TREO intercept just 200 metres from the existing resource envelope, signals that the mineralised body extends well beyond current boundaries. Such expansion not only adds tonnage but also improves the grade profile, positioning Araxá for a more robust reserve conversion and a stronger case in forthcoming feasibility work.

Strategically, Araxá aligns with globally significant carbonatite‑hosted projects like the United States’ Mountain Pass and Western Australia’s Mt Weld, both of which supply critical magnet rare earths for clean‑energy technologies. By demonstrating comparable scale and grade, St George could attract strategic partners and financing aimed at diversifying the supply chain away from dominant Asian producers. The ongoing data collection will feed a detailed feasibility study, potentially accelerating the timeline to commercial production and reinforcing the project's role in meeting rising demand for REEs and niobium in electric vehicles, wind turbines, and advanced electronics.
