Highlights:
Geophysical testing defines distinct sulphide mineralisation footprint at Saint John Project
Drone MobileMT and ground-based IP surveys planned across expanded strike zone
Rock-chip sampling ongoing at multiple prospects, with high-grade results for multiple metals
Riversgold Ltd (ASX:RGL) has reported new geophysical results from its Saint John Project in New Brunswick, Canada. This project is focused on identifying and advancing multi-metal mineralisation, including copper, gold, silver and antimony. The Saint John area spans a large landholding and is situated within a jurisdiction noted for infrastructure access and regulatory stability.
Distinct Geophysical Signature Detected in Sulphide Sample
At the Prince of Wales Prospect within the project, a key sulphide sample previously recorded strong grades of copper and silver. Petrophysical evaluation of this material has now revealed a unique geophysical footprint. Testing results indicate high induced polarisation and chargeability, combined with low resistivity. These characteristics make the sulphide mineralisation distinguishable for both airborne and ground geophysical detection.
This outcome has provided technical clarity on how the broader mineral system may be identified across the strike length of the project area. The chargeability and resistivity attributes are being used to define survey strategies for expanded exploration coverage.
MobileMT and Ground IP Surveys to Guide Drilling
The company has outlined the implementation of Drone Mobile Magnetotellurics (MobileMT) across key zones of the Saint John Project. This non-invasive airborne technique is suited to the large-scale mapping of conductive features. Follow-up surveys using ground-based induced polarisation and resistivity methods are scheduled to investigate specific localised anomalies identified through airborne scans.
The project has secured drilling approvals for an exploration campaign aligned with geochemical and geophysical data. The drilling work is designed to intersect the subsurface expression of mineralisation identified in the earlier fieldwork and sampling programs.
Sampling Continues Across Multiple Prospects
Ongoing work across the broader Saint John Project includes rock-chip sampling at the Little Lepreau Prospect. Early outcomes from this location have included high-grade readings for antimony, copper, silver and gold. These samples contribute to a broader interpretation of the mineral system and support the selection of zones for detailed follow-up.
Riversgold’s Saint John Project covers an extensive area close to the United States border, which offers logistical advantages. The regional footprint, geological setting, and geophysical response position the company to systematically advance the project through structured exploration.
Position Within Broader Sector and Index
Riversgold Ltd (ASX:RGL) operates within a segment of the mining industry focused on diversified metal projects. The inclusion of Gold Stocks, ASX 200 sector relevance further aligns with broader market interest in exploration activities across critical mineral projects. As geophysical and geochemical programs continue to define the mineralisation footprint, the project remains under active technical evaluation.
