Riversgold kicks off exploration at Saint John project in Canada Proactive uses images sourced from Shutterstock
Riversgold Ltd (ASX:RGL, FRA:RGV, OTC:RVSGF) has begun exploration activities at its Saint John gold-copper-antimony project in New Brunswick, Canada, with a high-resolution airborne geophysical survey set to begin this week.
The program is being executed by earn-in partner A.I.S. Resources and will involve a helicopter-borne magnetic survey covering 2,125 line kilometres at 50-metre spacing. Under the existing agreement, A.I.S. can earn up to 75% of the project by spending C$4.4 million over four years, with Riversgold retaining a 25% free-carried interest through to decision to mine.
Using advanced geometrics sensor technology, the survey is designed to generate high-resolution, low-noise magnetic data to map anomalies and refine drill targets across selected areas of the broader project.
Survey results are expected shortly after completion and will underpin the next phase of exploration.
“We are pleased to report that AIS are now fully engaged in advancing their exploration efforts at the St John Project. This project offers considerable potential for numerous high-grade gold, copper, antimony, silver and rare-earth maiden discoveries across its 101km2 area. This airborne survey will be critical in refining drill targets for later this year,” Riversgold chairman David Lenigas said.

The Saint John Project spans around 101km² and is considered prospective for IOCG-style mineralisation, offering exposure to:
Previous surface sampling has returned high-grade results, including:
Up to 70.4g/t gold
1,500g/t silver
17.6% copper
10.8% antimony
St Johns Project – Prince of Wales Prospect roadside cutting with exposed mineralisation.
These results highlight the project’s potential for multiple high-grade discoveries.
“With recent surface rock chip sampling showing encouraging results, with grades reaching up to 17.6% copper, 10.8% antimony, 70.4 g/t gold, and an impressive 1,500 g/t silver, we and AIS are very keen to see drilling underway in 2026,” Lenigas said.
The airborne survey marks the first step in a broader 2026 exploration program, with upcoming activities expected to include:
Interpretation of magnetic survey data
Follow-up ground geophysics and mapping
Drill targeting and drilling later in 2026
The survey is critical to defining priority targets and advancing the project toward drilling, as exploration ramps up across what is shaping as a multi-commodity system with significant scale potential.
