American Eagle Extends South Zone Discovery by over 300 Metres; Returns 91 m of 1.53% CuEq Within 167 m of 1.06% CuEqHighlights:South Zone Expansion:NAK25-57 intersected 167 m of 1.06% Copper Equivalent (CuEq), including 91 m of 1.53% CuEq, within 909 m averaging 0.41% CuEq from surface; this extends the NAK25-46 discovery more than 100 m west.NAK25-52 extends the high-grade NAK25-48 discovery by over 200 metres to the east, returning 85 m of 0.92% CuEq.Holes -57 and -52, together, extend the east-west strike length of the zone originally defined by NAK25-48 (77 m of 1.78% CuEq within 140 m averaging 1.23% CuEq) and NAK25-46 (97 m of 0.89% CuEq) to almost 500 metres.The South Zone continues to demonstrate strong potential for a large, high-grade system open to expansion both at surface and at depth.Toronto, Ontario--(Newsfile Corp. - December 11, 2025) - American Eagle Gold Corp. (TSXV: AE) (OTCQB: AMEGF) ("American Eagle" or the "Company") is pleased to report that recent drilling has expanded the high-grade South Zone at its NAK copper-gold porphyry project in British Columbia, Canada.Drill holes NAK25-57 and NAK25-52 intersected significant intervals of high-grade mineralization, extending the high-grade South Zone discovery in NAK25-46 and NAK25-48 (news release here) to almost 500 metres in an east-west direction. The South Zone remains open along strike, with follow-up drilling already undertaken to further define its continuity and to expand it both down- and up-dip."These latest drill results at NAK underscore the exceptional potential of this large-scale copper-gold system," said Anthony Moreau, CEO of American Eagle. "We are defining and expanding a high-grade core at depth that appears to feed into the extensive near-surface mineralization. It is evident that high-grade mineralization is extensive at depth, and that it may show strong continuity with surface zones and thereby confirm the significance of this discovery and the NAK Project."View Cross Section of Expanding High Grade South ZoneView Interactive 2D Map of NAKView Interactive 3D Model of NAKView Core Photos for Released HolesWatch: Webinar with Anthony Moreau, Charlie Greig and Neil ProwseNAK25-NAK25-57 Assay Results (Table 1) and Details*HoleFromTo (m)Length (m)Cu %Au g/tAg g/tMo ppmCuEq %NAK25-57776867910.700.73.13231.53WithinNAK25-577769431670.510.472.22771.06WithinNAK25-576038672640.380.381.51770.79WithinNAK25-576039433400.360.311.41870.73WithinNAK25-57449539090.200.181.2850.41 Cross Section | View Hole Location * Copper Equivalent (CuEq) shown in Tables for drill intercepts are calculated on the basis of US$ 3.75/lb for Cu, US$ 1,900/oz for Au, US$ 25/oz for Ag and US$ 25/lb for Mo, with 80% metallurgical recoveries assumed for all metals (since it's unclear what metals will be the principal products, assuming different recoveries is premature at this stage). The formula is: CuEq = Cu % + (Au grade in g/t x (Au recovery / Cu recovery) x [Au price ÷ 31] / [Cu price x 2200]) + (Ag grade in g/t x (Ag recovery / Cu recovery) x [Ag price ÷ 31] / [Cu price x 2200] + (Mo grade in % x (Mo recovery / Cu recovery) x [Mo price x 2200] / [Cu price x 2200]). The assays have not been capped.NAK25-57 was drilled to the west-northwest to test the continuity of mineralization to depth from a collar location approximately 400 m southeast of the near surface high-grade South Zone. Moderate grade mineralization from surface gave way abruptly at approximately 600 metres downhole to consistently higher grades characterized by disseminated and vein-hosted chalcopyrite and bornite mineralization within dark magnetite-biotite altered sandstone and conglomerate. As the drill hole traversed farther to the west, the tenor of mineralization decreased, being characterized by an increase in the relative proportions of pyrite and pyrrhotite versus chalcopyrite. The location of the strongest mineralization in this hole pushes the known extent of deep, high-grade mineralization over 100 m west of the strong zone intersected in NAK25-46. The zone remains open at depth to the north, where there has been little testing of what appears in part to be a sub-horizontal higher grade body.
