Amex Expands Central Polymetallic Zone - Drills 39.06 g/t Au, 331.92 g/t Ag, 1.14% Cu, 3.38% Zn, and 2.35% Pb over 1.30 m

Montreal, April 8, 2025 - Amex Exploration Inc. (TSXV: AMX) (FSE: MX0) (OTCQX: AMXEF) ("Amex" or "the Company") is pleased to announce results from its ongoing drill program at the Perron Project, located in northwestern Abitibi, Quebec (see Figure 1). Today's results from PEG-25-854 have expanded the mineralized footprint of the Central Polymetallic Zone (CPZ) to the west near surface by approximately 130 m (see Figures 2-3).

CPZ Drill Results:

• 39.06 g/t Au, 331.92 g/t Ag, 1.14% Cu, 3.38% Zn and 2.35% Pb over 1.30 m, including 48.27 g/t Au, 468.00 g/t Ag, 1.72% Cu, 4.48% Zn and 3.21% Pb over 0.80 m at a vertical depth of ~105 m - hole PEG-25-854

Jacques Trottier, PhD, Executive Chairman of Amex Exploration commented, "The Central Polymetallic Zone had not been drilled since the discovery of the High Grade Zone in late 2018, until last year's intercept of 134.36 g/t Au over 1.80 m (see November 6, 2024 Press Release), which extended the zone at depth down plunge. Today's results have extended the zone up plunge, westwards and towards surface and indicates that there is much more room for growth. As can be seen in Figure 4; by observing the gold to silver ratio, we can highlight zones of polymetallic mineralization. Our geology team has identified the potential for the extension of the CPZ to continue at depth, where there is a possible correlation with the Donna Copper Zone, found just north of the High Grade Zone. This model would match with other Volcanogenic Massive Sulfide (VMS) orebodies in the region such as the historical Normétal Mine, which was zinc-rich close to surface and more copper-rich at depth."

Central Polymetallic Zone

The CPZ is interpreted as a discordant linear volcanogenic hydrothermal feeder crosscut by gold bearing quartz-sulfide veins. The quartz-sulfide veins observed in PEG-25-854 (see Figure 5) are interpreted as syn-tectonic. The gold-rich veins are mineralized in chalcopyrite, sphalerite, pyrite, pyrrhotite, and galena. Silver values being almost ten times higher than gold is very typical of the CPZ. Higher gold grades are related to higher sulphide contents and are correlative either with zinc or copper values.

Since closing of the database on June 30, 2024 for the Mineral Resource Estimate and the Preliminary Economic Assessment, subsequent drilling has successfully intercepted both the up and down plunge extensions of the CPZ zone. PEG-25-854 has unlocked CPZ mineralization close to surface towards the west, while PE-24-801 found the potential downwards extension of the zone to the east (see November 6, 2024 Press Release).

Qualified Person and QA&QC

Jérôme Augustin P.Geo. Ph.D., (OGQ 2134), an Independent Qualified Person as defined by Canadian NI 43-101 standards, has reviewed and approved the geological information reported in this news release. The drilling campaign and the quality control program have been planned and supervised by Jérôme Augustin. Core logging and sampling were completed by Laurentia Exploration.

The quality assurance and quality control protocols include insertion of blank or standard samples every 10 samples on average, in addition to the regular insertion of blank, duplicate, and standard samples accredited by Laboratoire Expert and ALS Canada Ltd, during the analytical process.

For all analyses targeting gold mineralization, gold values are estimated by fire assay with finish by atomic absorption. Values over 3 ppm Au are reanalyzed by fire assay with finish by gravimetry by Laboratoire Expert Inc, Rouyn-Noranda. Samples containing visible gold mineralization are analyzed by metallic sieve. For additional quality assurance and quality control, all samples were crushed to 90% less than 2 mm prior to pulverization, in order to homogenize samples which may contain coarse gold.

For base gold and base metals analysis, the samples were shipped to ALS Rouyn-Noranda. Gold values are estimated by fire assay with finish by atomic absorption. Zinc, Copper and Silver values are estimated by four acid digestion multi elements Inductively Coupled Plasma - Atomic Emission Spectroscopy (ICP-AES), ME-ICP61. Zinc values over 1%, copper values over 1% and silver values over 100 g/t are estimated by four acid digestion ICP-AES, OG62.

The Qualified Person has not completed sufficient work to verify the historical information on the Property or neighbouring projects, particularly in regards to historical drill results. However, the Qualified Person believes that drilling and analytical results were completed to industry standard practices. The information provides an indication of the exploration potential of the Property but may not be representative of expected results.
