Amex Gold Mining has made significant high-grade gold discoveries, along with copper-rich volcanogenic massive sulphide (VMS) zones, at its 100%-owned Perron Gold Project, located approximately 110 kilometres north of Rouyn-Noranda, Quebec. The Perron Project in Quebec consists of 183 contiguous claims for a surface area of 65.75 km². The project hosts both bulk-tonnage and high-grade gold mineralization styles. Eldorado Gold is a strategic 27% investor.

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 570.94 km². 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 Normétal. It is also in close proximity to several process plants owned by major gold producers.

Amex delivered a positive feasibility study:
Gold production to average 147,000 oz per year over the 5 years of commercial Phase 1 production at an All in Sustaining Cost ("AISC") of USD$910/oz Au

Projected Post-Tax IRR of 114.6% and Post-Tax NPV5 of CAD$1.13 billion generated from a Cumulative Undiscounted Post-Tax Cash Flow of CAD$1.44 billion at an assumed gold price USD$3,500/oz

The Phase 1 Feasibility Study evaluates an initial development scenario at Perron, building on the broader potential outlined in the September 2025 PEA, which indicated a potential mine life of approximately 17 years1

Phase 1 mine development consists of two (2) years pre-production, followed by five (5) years of commercial mining and toll milling operations

Executing a toll milling approach reduces risks and accelerates production schedule targeting revenue in 2028

Proven and Probable mineable reserve of 1,989 kilotonnes at a grade of 12.1 grams per tonne, for 774,000 ounces of gold mined

Low initial capital cost estimate of CAD$193.9 million

After-tax payback period of 0.5 years
