St George Mining (ASX: SGQ) has upped the ante in Brazil with a bold geophysical exploration initiative at its 100‑percent‑owned Araxá Niobium and Rare Earth Elements (REE) project. The program aims to expand high‑grade zones and bolster the company’s ambitious resource expansion strategy. Despite only ~10% of the Araxá tenement being drilled so far—and minimal testing beyond 100 m depth—initial assays have revealed compelling mineralisation, including up to 8% Nb₂O₅, 33% TREO, and 32% P₂O₅. These grades signal substantial upside potential, prompting an advanced geophysical campaign to reveal hidden deposits before drilling the next stage.
Covering approximately 270 km of flight distance at a high resolution of 25 m line spacing, this drone‑based magnetic survey seeks subtle geophysical variations. These can indicate structural features, lithological boundaries, and mineralisation zones—essential for precise drill targeting. Scheduled for later in July on a 50 m x 50 m grid, the Horizontal-to-Vertical Spectral Ratio (HVSR) seismic method maps basement depths and weathering profiles. It’s non-invasive, cost-efficient, and perfect for guiding deep drilling operations.
