American Eagle drills 618 m of 0.77% CuEq at Nak

Executive Summary

• American Eagle Gold Corp. released new drill results from its 100%-owned Nak project in British Columbia, demonstrating significant expansion and continuity within the high-grade South Zone.
• Hole NAK25-80 intersected 618 metres of 0.77% copper equivalent (CuEq) from surface, linking near-surface gold-rich mineralization to a high-grade core at depth.
• Stepout drilling (NAK25-73, NAK25-75, NAK25-79) extends the South Zone corridor approximately 750 metres east and 500 metres south along the Babine porphyry stock margin, reinforcing a district-scale growth profile and leaving the system open to further expansion.

Key Details

• Hole NAK25-80: 618 m of 0.77% CuEq from surface. Confirms strong continuity within the South zone high-grade core. Collared into Babine biotite feldspar porphyry stock with mineralized stockwork to 142 m (101 m of 0.68 g/t Au and 0.14% Cu). Below 142 m to 659 m, intersected sandstone/conglomerate intruded by mafic dikes with increasingly copper-rich mineralization, featuring chalcopyrite, bornite, molybdenite, and quartz-anhydrite veins.
• South Zone Eastern Expansion: Stepout holes NAK25-73, NAK25-75, and NAK25-79 extend the mineralized corridor ~750 m east and ~500 m south along the porphyry margin, open to the east and south.
• Hole NAK25-73: Collared from the same pad as NAK23-09, drilled shallowly west. Intersected 1,032 m grading 0.25% CuEq from surface, primarily within stratified rocks marginal to the Babine porphyry stock, with higher-grade intervals associated with varied dike compositions.
• Hole NAK25-79: Collared 320 m southeast of NAK25-73, drilled southwest. Intersected sporadic copper mineralization that increased substantially below 400 m, extending mineralization >500 m south of the Babine porphyry stock boundary. Highest-grade intervals hosted in coarser-grained sandstone and conglomerate.
• Continuity & Prior Results: Builds on NAK25-78 (802 m of 0.71% CuEq from surface) and the Feb. 25, 2026 release highlighting NAK25-70 (901 m of 0.43% CuEq from surface), reinforcing a large, coherent mineralized body extending from surface to significant depth.
• QA/QC Protocol: Core halved on site and submitted to ALS Geochemistry (Langley, BC). ISO/IEC 17025 accredited. Sample lengths range from 70 cm to 3 m. Analyzed in 50-sample batches containing 10% QA/QC (1 Au-Cu standard, 2 coarse reject duplicates, 2 blanks). Gold analyzed via fire assay fusion + ICP-AES; Cu, Ag, Mo, and trace elements via four-acid digestion + ICP-MS. All 2024 Au/Cu standards passed within three standard deviations.
• Project Context: Nak project located in the Babine Cu-Au porphyry district, central BC, with excellent infrastructure. Historical drilling (since 1960s) was shallow. Recent drilling (2022-2024) identified deeper/higher-grade zones within a broader system. The company completed a 31,500 m drill program in 2025 to expand the mineral footprint.
