A.I.S. RESOURCES SIGNS EARN-IN AGREEMENT WITH RIVERSGOLD ON THE NEW COPPER/GOLD/ANTIMONY DISCOVERY AT SAINT JOHN, NEW BRUNSWICK

A.I.S. Resources Ltd. has entered into an earn-in agreement with Riversgold Ltd., granting A.I.S. the right to acquire up to a 75-per-cent interest in the new Saint John IOCG (iron oxide copper-gold)/porphyry project located in New Brunswick, Canada.

A.I.S. chief executive officer 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 mineralization, excellent infrastructure and district-scale potential provides A.I.S. 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 A.I.S. enables Riversgold to retain a meaningful exposure to the upside of the Saint John project while A.I.S. commits to an aggressive exploration program. A.I.S., 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 A.I.S. immediately getting onto 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 square kilometres in a Tier 1 mining jurisdiction. Located just 20 kilometres west of Saint John, N.B., and 50 kilometres from the U.S. border, the project benefits from exceptional infrastructure, including highways, rail, deepwater port, power stations and a skilled local work force.

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

  • Commence 2,000-metre maiden RC/DD (reverse circulation/diamond drilling) drill program at Little Lepreau in 2025/2026.

Transaction terms:

• On signing: A.I.S. to issue 2.86 million shares at five cents per share to Riversgold;
