St George Mining Launches Araxá Permitting for 111-Million-Tonne Rare Earths-Niobium Resource

Highlights

• St George Mining submitted environmental studies for its Araxá mine and refining complex in Minas Gerais, Brazil.
• The resource totals 111.2 million tonnes grading 3.57% TREO and 0.57% Nb₂O₅, with ~760,000 tonnes of NdPr oxides.
• About 68% of the resource is Measured and Indicated, with near-surface mineralization adjacent to CBMM's niobium operation.
• Permitting is a milestone, but feasibility-level answers on metallurgy, recoveries, capex, and radionuclides remain critical.
• St George is developing technology to remove lower-value cerium and lanthanum and upgrade the magnet rare earth fraction.

A giant resource has begun the long journey from drill core to cash flow. St George Mining (ASX: SGQ; OTC: SGQMF) has started environmental permitting (opens in a new tab) for its Araxá rare earths-niobium project in Minas Gerais, Brazil, submitting environmental studies for a proposed mine, processing and refining complex. The headline geology is substantial: 111.2 million tonnes grading 3.57% TREO and 0.57% Nb₂O₅, containing approximately 3.98 million tonnes TREO, including 760,000 tonnes NdPr oxides.

REEx Insight: Grade Is Not a Business Model

Araxá deserves attention. About 68% of its resource is Measured and Indicated, mineralization begins near surface, and the project sits beside CBMM's world-leading niobium operation—an unusually attractive combination of grade, infrastructure, and mining jurisdiction. But both a press release and The West Australian's (opens in a new tab) description of a project seemingly destined to become globally significant runs ahead of the evidence. A mineral resource is not an ore reserve, and TREO is not saleable NdPr. The decisive question is metallurgy.

Between the Resource and the Refinery

St George's numbers are JORC-compliant and backed by extensive drilling—not merely promotional exploration targets. Yet investors still need feasibility-level answers on recoveries, reagent consumption, capex, opex, radionuclides, product specifications, and economics. That omission matters because much of TREO can comprise lower-value cerium and lanthanum. St George itself is developing technology to remove Ce/La and upgrade the magnet and heavy-rare-earth fraction.

Permitting therefore advances Araxá, but Worley's feasibility work and metallurgical flowsheet may ultimately matter more than another spectacular drill hole.
