AMEX ANNOUNCES FILING OF UPDATED MRE TECHNICAL REPORT FOR THE PERRON PROJECT

Amex Exploration Inc. has filed a National Instrument 43-101, Standards of Disclosure for Mineral Projects, updated mineral resource estimate (MRE) technical report for Amex's 100-per-cent-owned Perron gold project in Quebec, Canada, with an effective date of May 21, 2025. Report results were previously announced in Amex's news release dated May 21, 2025.

P&E Mining Consultants Inc. is responsible for the overall report, which was prepared in collaboration with Laurentia Exploration Inc. The qualified persons (QPs), as defined under NI 43-101, are Antoine Yassa, PGeo, Charles Spath, MSc, PGeo, Yungang Wu, MSc, PGeo, Eugene Puritch, PEng, FEC, CET, and Jerome Augustin, PGeo, PhD.

The report is available on company's website and on SEDAR+.

Key highlights of the updated MRE were:

• Mineral resource estimate: All constrained zones contain 1,615,000 ounces (oz) of measured and indicated resources at 6.14 grams per tonne (g/t) gold (Au) in 8,183,000 tonnes, and an inferred resource of 698,000 oz at 4.31 g/t Au in 5,044,000 tonnes (t);
• Champagne zone (formerly the high-grade zone) contains resources of 831,000 oz of measured and indicated mineral resources at a grade of 16.20 g/t Au in 1,594,000 t, and 128,000 oz of inferred at a grade of 9.83 g/t Au in 406,000 t;
• 172-per-cent increase in measured and indicated resources over the 2024 mineral resource estimate, with a 43-per-cent increase in grade realized;
• Estimates based on high-grade, selective narrow vein mining operation approach;
• Additional mineral resource potential: to expand the deposits in all directions for future mineral resource estimation. With a land package increase from 45.6 to 197.5 square kilometres (km) providing additional new targets to be explored (see news release dated March 25, 2025).

About Amex Exploration Inc.

Amex Exploration has made significant high-grade gold discoveries, along with copper-rich volcanogenic massive sulphide (VMS) zones, at its 100-per-cent-owned Perron gold project, located approximately 110 kilometres north of Rouyn-Noranda, Que. The project comprises 117 contiguous claims (45.18 square km), and hosts both bulk-tonnage and high-grade gold mineralization styles.

When combined with the adjacent Perron West project, which includes 48 claims (17.37 square km) in Quebec and 35 claims (134.55 square km) in Ontario, the consolidated land package spans a district-scale 197.52 square km. This extensive property lies within highly prospective geology favourable for both high-grade gold and VMS mineralization.

The project benefits from excellent infrastructure; it is accessible by a year-round road, located just 20 minutes from an airport and approximately eight km from the town of Normetal. It is also in close proximity to several milling operations owned by major gold producers.

We seek Safe Harbor.
