AMEX EXPLORATION RECEIVES KEY PERMITS FOR PERRON BULK SAMPLE AND COMPLETES FINANCIAL GUARANTEE REQUIREMENT

Amex Exploration Inc. has obtained the main required governmental authorizations for the execution of its 40,000-tonne underground bulk sampling program at the Perron gold project, located within the locality of Valcanton, near Normetal. Field preparatory work is planned to begin during the month of April, with the objective of initiating portal construction in early summer 2026.

These authorizations include, among others, the ministerial authorization issued by the Ministere de l'Environnement, de la Lutte contre les Changements Climatiques, de la Faune et des Parcs (MELCCFP) and the Authorization for Impact Work (ATI) issued by the Ministere des Ressources naturelles et des Forets (MRNF).

In addition, the company has completed the payment of the financial guarantee required under Quebec's Mining Act for its rehabilitation and restoration plan. This guarantee is a critical component of the regulatory framework, ensuring that funds are secured upfront to fully restore the site upon completion of activities.

The receipt of these permits, combined with the completion of the financial guarantee, mark a key milestone in the advancement of the Perron project and allows the company to fully transition into the execution phase of its 40,000-tonne bulk sampling program. Much of the infrastructure installed for this bulk sample program will support the phase 1 production. Amex is on track to release the phase 1 feasibility study, which contemplates a toll milling scenario, in the coming weeks.

Over the past several months, Amex has initiated several key critical path steps to accelerate the start of the bulk sample activities. Notably, the company has proceeded with the ordering of long-lead items, including a water treatment plant, as well as electrical components required for the installation of the dedicated Hydro-Quebec power line connecting the site to the existing grid.

In parallel, major tenders have been launched, including for the construction of the portal and the mining contract. Bids are expected in the coming days, positioning the company for rapid contractor mobilization.

The company has also initiated an extensive hiring process to support the execution of upcoming work, with several key positions currently being filled. This effort is aimed at establishing a strong operational team aligned with the project timeline.

Finally, Amex has started a grade control drill program for which results were published on Feb. 18, 2026, and Feb. 26, 2026. Grade control highlights to date include:

• 76.51 grams per tonne Au and 7.57 g/t Ag over 6.40 metres, including 312.60 g/t Au and 25.85 g/t Ag over 1.55 m at a vertical depth of about 200 m in hole PE-19-47W1;
• 110.05 g/t Au and 7.20 g/t Ag over 2.15 m, including 233.96 g/t Au and 14.90 g/t Ag over 1.00 m at a vertical depth of about 145 m in hole PE-26-894;
• 52.36 g/t Au and 8.90 g/t Ag over 0.5 m at a vertical depth of about 130 m in hole PE-21-371W1.

The grade control results published to date support the resource block model, thereby reducing execution risk of the bulk sample.

Victor Cantore, president and chief executive officer of Amex Exploration, commented: "Securing these authorizations is a decisive milestone that propels the Perron project into its next phase of execution. Our pro-active preparation -- through early procurement and tenders -- positions us to move efficiently toward bulk sampling, confirming the project's potential and enhancing long-term value for shareholders and communities alike."

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 Perron project in Quebec consists of 183 contiguous claims for a surface area of 65.75 square km. The project hosts both bulk-tonnage and high-grade gold mineralization styles.

When combined with the adjacent and contiguous Perron West project and Abbotsford and Hepburn projects (including additional claims acquired through staking) in Ontario, the consolidated land package spans a district-scale 502.53 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 30 minutes from an airport and approximately 6.5 km from the town of Normetal. It is also in close proximity to several process plants owned by major gold producers.

We seek Safe Harbor.
