St George Mining Limited (ASX: SGQ) is an Australian-based mineral exploration company headquartered in West Perth, Western Australia. The company focuses on critical minerals projects in Australia and Brazil, targeting niobium, rare earth elements (REE), nickel, copper, lithium, and related metals essential for steelmaking, electronics, batteries, and clean energy technologies.
Its flagship Araxá Project in Minas Gerais, Brazil—acquired in February 2025—hosts a world-class JORC resource of 70.91 million tonnes at 4.06% TREO and 0.62% Nb₂O₅ (plus additional niobium inventory), with high-grade mineralization from surface enabling potential low-cost open-pit mining. Located adjacent to CBMM's major niobium operations, the project benefits from established infrastructure and recent advancements including resource expansions, drilling successes, and the appointment of Worley as feasibility technical advisor.
In Western Australia, St George advances the Mt Alexander Project, featuring nickel-copper-cobalt-PGE discoveries and lithium prospects.
