St George Mining initiates advanced geophysical programs at its Brazilian Araxá Project
New airborne and seismic surveys to enhance high-grade mineral targeting and support ongoing drilling
Project location adjacent to established niobium operations with strong infrastructure access
St George Mining Ltd (ASX:SGQ), listed on the ASX 300, has launched a new geophysical phase at its Araxá Niobium and Rare Earth Elements Project in Brazil. The strategic development aims to refine resource modelling and support ongoing exploration efforts through high-resolution data gathering.
This phase of work builds upon earlier drilling campaigns and is expected to play a pivotal role in advancing project definition through a combination of magnetic and seismic technologies.
High-Resolution Geophysics Underway Across Key Zones
The current program incorporates two distinct survey methods: an airborne magnetic survey and a passive seismic study. The magnetic component, already in progress, involves drone-based data collection with a tight line spacing to trace subsurface variations associated with mineralisation and geological boundaries.
Meanwhile, the seismic work is set to commence shortly using Horizontal-to-Vertical Spectral Ratio (HVSR) techniques. This approach will help map depth to unweathered basement rock, critical in identifying areas with greater mineral concentrations, particularly within the project’s regolith zone.
These initiatives are designed to optimise the accuracy of future drilling locations and expand the known mineralised footprint.
Chair Outlines Importance of Broader Geological Mapping
According to St George Mining’s executive chairman, the integrated geophysical program is set to provide a comprehensive geological understanding across the Araxá tenement. The focus remains on identifying priority targets for deeper drilling and enhancing the efficiency of ongoing exploration operations.
With only a small portion of the total project area previously tested through drilling and limited investigation below shallow depths, the updated data will contribute significantly to refining the company’s geological model and resource expansion strategy.
Ongoing Campaign Supported by Infrastructure and Strategic Positioning
The Araxá Project benefits from a location adjacent to one of the world’s most prominent niobium operations. Past exploration confirmed the presence of niobium and rare earth mineralisation, and the current drilling program aims to expand the initial resource base defined earlier this year.
The project is well supported by access to existing infrastructure, including transportation and workforce capabilities. Regional support for mineral development in Minas Gerais also reinforces the company’s operational momentum.
