St George Mining Delivers Thickest-Ever Drill Result at Araxá Rare Earths & Niobium Project

St George Mining Ltd (ASX: SGQ) has reported its most significant drilling achievement yet at the company’s 100%-owned Araxá Rare Earths and Niobium Project in Minas Gerais, Brazil. This new result marks the thickest high-grade drill intersection recorded at the project to date, underlining the exceptional scale and quality of the mineral system and reinforcing the case for a major resource upgrade.

The standout result came from diamond hole AXDD004, which intersected a massive 139.45 metres of mineralisation from surface, assaying 4.05% Total Rare Earth Oxides (TREO) and 0.55% niobium pentoxide (Nb₂O₅). This intercept surpasses previous long intersections at Araxá and highlights the continuity of high-grade rare earths and niobium mineralisation.

Key highlights include:

139.45 m @ 4.05% TREO & 0.55% Nb₂O₅ from surface — the thickest high-grade intercept at the project so far.

Mineralisation begins at surface, suggesting strong open-pit mining potential in future studies.

Additional broad intervals from other holes confirm the widespread nature of the mineralised system.

St George’s Executive Chairman John Prineas commented that this result represents a “major milestone” in the Araxá drilling program and strengthens confidence in the project’s world-class status. The ongoing drilling campaign continues to deliver consistent high-grade results and expand mineralisation beyond previously defined limits.

With additional assays pending from recently completed drill holes, the company anticipates further growth in both resource size and grade. The strong continuity and scale of the mineralised system support potential enhancements to the existing Mineral Resource Estimate and future economic studies.
