St George Mining (ASX:SGQ) announced a major high-grade niobium discovery 400m northwest of its existing mineral resource estimate at the 100%-owned Araxá Rare Earths and Niobium Project in Minas Gerais, Brazil.
Expansion drilling has returned results, including 81.5m at 1.27% Nb₂O₅ from surface, with standout intervals of 43m at 2.01% Nb₂O₅ and 10.5m at 3.41% Nb₂O₅.
The discovery lies within the world-renowned Barreiro Carbonatite, adjacent to CBMM’s leading niobium operation.
Executive Chairman John Prineas described the results as "outstanding," highlighting the continuity and scale of the mineral system, with mineralisation open in all directions.
The discovery's surface-level high grades offer a potential commercial advantage, supporting future open-pit mining.
