A.I.S. Resources Signs Earn-In Agreement with Riversgold on
the New Copper/Gold/Antimony Discovery at Saint John, New
Brunswick
Significant results reported for Antimony up to 10.8%, Gold up to 70.4
g/t, Copper up to 17.6% and Silver up to 48 ounces per tonne
Vancouver, B.C. – September 15, 2025 – A.I.S. Resources Limited (TSXV: AIS, OTC-Pink: AISSF)
(“AIS” or the “Company”) is pleased to announce that it has entered into an earn-in agreement
with Riversgold Ltd. (ASX: RGL) (“Riversgold”), granting AIS the right to acquire up to a 75%
interest in the new Saint John IOCG/Porphyry Project located in New Brunswick, Canada.
AIS CEO, Marc Enright-Morin commented, “We are excited to partner with Riversgold on this
very exciting newly discovered Saint John Project. The combination of very high-grade
mineralisation, excellent infrastructure, and district-scale potential provides AIS with a
unique opportunity to advance a possible IOCG/porphyry system in one of Canada’s most
mining-friendly jurisdictions. Saint John is exploration and drill ready with two drill
programs already approved. Its unique location near the coast means we can explore here in
a meaningful way all year round and we look forward to getting the drills turning and come
up with the discovery hole.”
Riversgold Executive Chairman, David Lenigas added, “This transaction with AIS enables
Riversgold to retain a meaningful exposure to the upside of the Saint John Project, while AIS
commits to an aggressive exploration program. AIS, as a Canadian company, is much better
placed to move this incredible gold/silver/copper/antimony discovery forward whilst
Riversgold shifts it focus towards developing its large porphyry gold project near Kalgoorlie
in Western Australia. We look forward to assisting AIS immediately getting on to the ground
and advancing drilling and development across this highly prospective district.”
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 km² in a Tier-1 mining jurisdiction. Located just 20 km west of Saint
John, New Brunswick and 50 km from the U.S. border, the project benefits from exceptional
infrastructure, including highways, rail, deep-water port, power stations, and a skilled local
workforce.
Riversgold have released multiple press releases on the Australian Stock Exchange over the
past year as they have moved this project up the value chain. Geological results were
