Amex Exploration Wins Prestigious Discovery of the Year Award from the Quebec Mineral Exploration Association

Montreal, Quebec--(Newsfile Corp. - October 31, 2025) - Amex Exploration Inc. (TSXV: AMX) (FSE: MX0) (OTCQX: AMXEF) ("Amex" or the "Company") is pleased to announce that it has been awarded the Discovery of the Year by the Quebec Mineral Exploration Association (QMEA) for its outstanding contribution to mineral exploration through the company's exceptional discovery on its Perron Gold Property, located in the Abitibi Greenstone Belt of northwestern Quebec.

This prestigious award recognizes a discovery that has generated a significant ripple effect in exploration activity, not only on the property itself but also across the surrounding region. The Discovery of the Year highlights projects that demonstrate strong continuity, geological significance, and compelling economic potential-criteria that the Perron Gold Project has decisively met.

"We are deeply honoured to receive this recognition from the QMEA," said Victor Cantore, President and CEO of Amex Exploration. "This award is a testament to the hard work, technical excellence, and vision of our entire exploration team. The Perron discovery continues to inspire renewed exploration interest throughout the Abitibi region, underscoring Quebec's world-class position as a premier mining jurisdiction."

The Perron Gold Property discovery has unveiled multiple high-grade gold zones, including the Champagne Zone which boast some of the highest-grade gold intercepts reported in Canada in recent years. These results have drawn attention from across the exploration community and have contributed to a surge in regional staking and investment.

Amex Exploration's ongoing drilling and exploration success at Perron continue to reveal a robust mineralized gold system with continuity and scalability. The project's economic potential and exploration upside have positioned it as one of Quebec's most promising gold discoveries in recent years.

The recent Preliminary Economic Assessment published by Amex Exploration highlights the project's economic potential with a Gold Mineral Resource Estimate (May 2025) of:

• 1.615 million ounces of Measured & Indicated @ 6.14 g/t Au in 8.18 MT
• 698,000 ounces of Inferred @ 4.31 g/t Au in 5.04 MT

The updated Preliminary Economic Assessment (PEA) (at US$3,400/oz gold, all number are Pre-tax) (September2025):

• IRR of 148.7%
• NPV (5%) of C$3.2 billion
• Cash flow of C$5.1 billion
• Payback period of only 0.2 years

"This award reflects the power of perseverance in exploration," added Cantore. "We are proud to contribute to the growth and vitality of Quebec's mining industry and look forward to advancing this exciting discovery towards production."

The Quebec Mineral Exploration Association (QMEA) annually presents the Discovery of the Year award to recognize excellence in exploration and the identification of new mineral resources that strengthen Quebec's mining future.

About Amex

Amex Exploration Inc. 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. On June 25, 2025, the MRNF converted the Perron claims from 117 to 135 contiguous claims, maintaining the same surface area of 45.18 km². The project hosts both bulk-tonnage and high-grade gold mineralization styles.

When combined with the adjacent Perron West Project, which includes 48 claims (17.37 km²) in Quebec and 35 claims (134.55 km²) in Ontario, the consolidated land package spans a district-scale 197.52 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 20 minutes from an airport, and approximately 8 km from the Town of Normétal. It is also in close proximity to several process plants owned by major gold producers.
