Riversgold (ASX:RGL) commenced a pivotal exploration phase at its Saint John Gold/Copper/Antimony Project in New Brunswick, Canada.
In a partnership with Canadian-listed A.I.S. Resources, the companies are deploying a high-resolution helicopter-borne magnetic survey this week to pinpoint critical drill targets across the 101km2 site.
The operation, managed by Geo Data Solutions GDS Inc., will utilise Geometrics G822 sensor technology to cover 2,125 line kilometres at a precise 50-metre spacing, ensuring high-confidence mapping of magnetic anomalies across the varied terrain of south-eastern Canada.
The technical surge follows a farm-out agreement established in late 2025, where AIS can earn a 75% interest in the project by investing CAD$4.4 million over four years.
Riversgold’s Chairman, David Lenigas, highlighted the project’s immense potential, noting that recent surface rock chip sampling has returned extraordinary grades, including 17.6% copper, 10.8% antimony, and gold reaching 70.4 g/t.
With the airborne survey set to begin on April 15, the data gathered will be instrumental in refining the exploration strategy.
The results are expected shortly after the survey’s completion, providing a roadmap for ground-based geophysics and mapping.
At the time of reporting, Riversgold’s share price was $0.013.
