A.I.S. Resources Acquires More Prospective Ground and Commences Field Exploration of Saint John Project, New Brunswick

May 21, 2026

Vancouver, British Columbia – A.I.S. Resources Limited (TSX-V: AIS • OTC PINK: AISSF) (the “Company” or “AIS”) is pleased to announce the expansion of land holdings at its Saint John Project, New Brunswick, and has commenced field exploration activities on the properties.

The Company has staked one additional mineral claim, Claim 12483, consisting of 47 claim cells covering approximately 1,175 hectares. The newly acquired claim is located southwest of the Company’s existing claim blocks and increases the Company’s prospective land position in the Saint John area to 12,550 hectares in four claim blocks.

The Company has also commenced a field exploration program on the Saint John Project. The program includes ground prospecting, geological mapping and rock sampling, and will also cover the newly acquired claim area. The program’s objective is to evaluate areas with limited historical sampling, identify additional mineralized zones and exploration targets, and assist in prioritizing potential drill targets for the Company’s planned diamond drilling program.

Based on historical exploration work, the Saint John Project currently includes three principal prospect areas: Prince of Wales, where copper, gold, silver, and lead mineralization has been reported; Little Lepreau, where copper, gold, antimony and silver mineralization has been reported; and Headaway, where copper, gold, and silver mineralization has been reported.

Marc Enright-Morin, CEO of A.I.S. Resources, said, “The expansion of our land position at the Saint John Project is an important step in consolidating a prospective exploration package in a region with encouraging historical mineral occurrences. With fieldwork now underway, our technical team is focused on advancing the project through systematic prospecting, mapping and sampling. This work is intended to improve our understanding of the mineralized systems, fill gaps in the historical dataset, and help define priority targets for follow-up drilling. We believe the Saint John Project offers strong exploration upside, and we look forward to updating shareholders as results become available.”

The Company believes that the expanded land position provides additional exploration potential along prospective trends associated with the known mineral occurrences. Results from the current field program will be used to refine the geological model and support future exploration planning.
