AIS Resources has commenced a detailed helicopter-borne magnetic survey over Riversgold’s Saint John Gold/Copper/Silver/Antimony Project in New Brunswick, aiming to sharpen drill targets ahead of 2026 exploration drilling.
- AIS Resources begins 2,125 km helicopter magnetic survey
- Survey targets high-confidence magnetic anomalies to refine drilling
- AIS can earn 75% of project by spending C$4.4 million over four years
- Riversgold retains 25% free-carried interest to decision to mine
- Previous sampling showed high-grade gold, copper, silver, and antimony
AIS Resources Commences Critical Survey Phase
Riversgold’s earn-in partner, Canadian-listed AIS Resources (TSXV:AIS), has kicked off a high-resolution helicopter-borne magnetic survey across selected zones of the Saint John Project in New Brunswick, Canada. This survey, deploying advanced Geometrics G822 sensors over 2,125 line kilometres at 50-metre spacing, aims to deliver low-noise magnetic data critical for identifying magnetic anomalies that could signal mineralisation.
The survey marks a significant step in advancing the project’s exploration, as AIS works towards earning up to 75% ownership by investing C$4.4 million over four years. Riversgold will maintain a 25% free-carried interest through to any mining decision, preserving exposure to potential upside without immediate capital outlay.
High-Grade Surface Sampling Supports Project Potential
The Saint John Project’s promise is underpinned by recent surface rock chip sampling that revealed impressive grades, including up to 17.6% copper, 10.8% antimony, 70.4 g/t gold, and a striking 1,500 g/t silver. These results suggest the potential for multiple high-grade discoveries within the 101 km² tenure.
Chairman David Lenigas highlighted the survey’s role in refining drill targets planned for later in 2026, noting the project’s IOCG-style mineralisation potential that includes critical minerals like rhenium alongside precious and base metals.
Survey to Inform Next Exploration Stages
Following completion of the airborne survey, AIS will interpret the data to guide subsequent ground-based geophysics, detailed mapping, and drill targeting. This phased approach reflects a methodical exploration strategy designed to de-risk drilling and enhance discovery chances.
The timing aligns with Riversgold’s broader exploration momentum, including recent advances at its Kalgoorlie Gold Project where the company has been securing key tenements and accelerating drilling plans. This ongoing activity, such as the accelerated Kalgoorlie gold project, demonstrates Riversgold’s dual focus on advancing multiple assets with significant resource potential.
While the survey and planned drilling remain subject to geological and operational risks, the current campaign represents a clear step forward in unlocking value from the Saint John Project’s promising geology.
Bottom Line?
The magnetic survey sets the stage for targeted drilling in 2026, but the ultimate value hinges on how well the geophysical data translates into mineral discoveries.
Questions in the middle?
- Will the magnetic survey identify compelling drill targets that justify a sizeable 2026 drilling program?
- How might AIS’s earn-in progress influence Riversgold’s capital allocation and project focus?
- What impact will the Saint John Project’s exploration success have on Riversgold’s broader portfolio momentum?
