St George Mining Ltd (ASX:SGQ, FRA:S0G, OTC:SGQMF) has delivered its thickest and most compelling drill result yet from the Araxá Rare Earths and Niobium Project in Brazil, with a standout intercept of 178.7 metres at 4.34% total rare earth oxides (TREO) and 0.75% niobium oxide (Nb₂O₅) from surface.

The result — the thickest mineralised interval recorded at Araxá to date — underscores the scale, grade and near-surface continuity of the deposit, reinforcing its status as one of the most significant undeveloped rare earths and niobium projects globally.

It forms part of a broader batch of assay results from 15 diamond drill holes, with multiple wide, high-grade intercepts continuing to demonstrate consistency across the system.

Among the highlights:

• 165.3m at 4.28% TREO and 0.61% Nb₂O₅ from surface

• 150.2m at 4.64% TREO and 0.59% Nb₂O₅ from surface

• 163.65m at 3.29% TREO and 0.45% Nb₂O₅ from surface

• 81.05m at 5.14% TREO and 0.64% Nb₂O₅ from surface

These results continue to highlight a defining feature of Araxá — very thick, high-grade mineralisation starting at surface, supporting the potential for a low-strip, open-pit mining operation.

Executive chairman John Prineas said the combination of scale and grade, particularly from surface, sets Araxá apart from comparable projects.

“The drilling results continue to show huge true widths from surface paired with very high grades,” he said.

“This unique combination is unrivalled among emerging rare earths and niobium developers,” he added. “The commercial advantage of high-grade mineralisation starting from surface — as opposed to 50 metres or even more than 100 metres below surface — cannot be underestimated.”

High-grade system continues to expand

Drilling at Araxá has now been running continuously for more than six months, with the current program designed to both expand and upgrade the mineral resource estimate.

The latest results demonstrate strong grade continuity over broad intervals and suggest further upside, with the mineral system remaining open in all directions and at depth.
