About the Saint John project

The Saint John project is a district-scale IOCG/porphyry exploration target providing strategic exposure to gold and silver (precious metals), copper (energy transition metal), and antimony (critical mineral).

The project covers 101 square kilometres in a Tier 1 mining jurisdiction. Located just 20 km west of Saint John, New Brunswick and 50 km from the United States border, the project benefits from exceptional infrastructure, including highways, rail, deepwater port, power stations and a skilled local work force.

Riversgold have released multiple press releases on the Australian Securities Exchange over the past year as they have moved this project up the value chain. Geological results were previously disclosed by Riversgold in press releases on ASX dated Jan. 29, 2025, and April 9, 2025.
