AMERICAN EAGLE EXPANDS SOUTH ZONE 750 METRES TO THE EAST AND FURTHER DEMONSTRATES CONTINUITY WITHIN HIGH-GRADE CORE, INTERSECTING 618 METRES OF 0.77% CUEQ FROM SURFACE

American Eagle Gold Corp. has released new drill results from its 100-per-cent-owned Nak project that further derisk and expand the South zone while reinforcing Nak's emerging district-scale growth profile. These results follow the company's Feb. 25, 2026, release, which demonstrated continuous stock-hosted mineralization over a 1.7-kilometre east-west trend, complementing this significant expansion by further extending mineralization over 500 metres south of the Babine porphyry stock.

Highlights:

• 618 m of 0.77 per cent copper equivalent from surface in NAK25-80, linking high-grade, at-surface gold-rich mineralization to high-grade core at depth;
• Continuity from surface to depth: NAK25-80 builds on prior long intervals, including NAK25-78 (802 m of 0.71 per cent CuEq from surface), and strengthens confidence in thickness and continuity of the South zone mineralization;
• Material stepout growth: NAK25-73, NAK25-75, NAK25-79 and NAK25-80 extend the South zone corridor approximately 750 m east and approximately 500 m south along the porphyry margin, open to the east and south;
• Strengthens the district-scale thesis: building on Feb. 25, 2026, footprint expansion and reinforces a high-grade core within a very broad mineralized envelope.

Hole NAK25-80 delivered a standout interval of 618 m averaging 0.77 per cent CuEq from surface. This result confirms strong continuity within the South zone high-grade core and further supports the concept of a large, coherent mineralized body extending from surface to significant depth, building on prior long-interval drilling in the South zone (including NAK25-78: 802 m of 0.71 per cent CuEq from surface).

Importantly, stepout drilling to the east (NAK25-73, NAK25-75 and NAK25-79) indicates a connected mineralized corridor along the southern margin of the Babine porphyry stock that can now be traced for at least approximately 750 m eastward from the South zone/Main zone area and approximately 500 m to the south. This materially increases the mineralized footprint of the South zone and leaves the corridor open to further expansion to the east and south.

Together, the Feb. 25 district-scale breakthrough, highlighted by NAK25-70's 901 m of 0.43 per cent CuEq from surface, and today's South zone results reinforce a clear growth pathway at NAK: advance the higher-grade South zone as the near-term core while systematically expanding and vectoring within a much larger, newly demonstrated mineralized system.

NAK25-80

NAK25-80 was drilled from near the western boundary of the high-grade historical gold or stockwork zone, which was further expanded by the company in drilling between 2022 and 2025. The drill hole was collared into rocks of the Babine biotite feldspar porphyry stock, which hosts mineralized stockwork to a depth of 142 m. This interval returned strong gold grades and strongly anomalous copper from surface (101 m of 0.68 gram per tonne gold and 0.14 per cent copper). Below 142 m and down to a depth of 659 m, the hole intersected sandstone and conglomerate that were intruded by mafic dikes, with mineralization becoming increasingly copper rich. The mineralization features localized zones of conglomerate clast replacement chalcopyrite and bornite, along with variably dense disseminations, and these are interspersed with quartz-anhydrite veins that host coarse aggregates of bornite and, in some places, molybdenite.

South zone eastern expansion

The additional holes in this release, NAK25-73, NAK25-75 and NAK25-79, successfully link the broad, low-to-moderate grade mineralization enveloping the high-grade South zone to near-surface mineralization previously intersected to the east in drill hole NAK23-09. Hole NAK25-73 was collared from the same pad as NAK23-09 and was drilled shallowly to the west, intersecting 1,032 m grading 0.25 per cent CuEq from surface, with mineralization occurring largely within stratified rocks marginal to the Babine porphyry stock to the north, with higher-grade intervals associated with dikes of a variety of compositions. NAK25-79 was collared 320 metres southeast of NAK25-73 and was drilled to the southwest. It intersected sporadic copper mineralization that increased substantially in tenor below 400 metres, extending the mineralization in that area over 500 metres to the south of the southern boundary of the Babine porphyry stock. The highest-grade mineralization in the hole was hosted by intervals of coarser-grained sandstone and conglomerate that are correlative with similarly well-mineralized rocks along strike to the northwest.

Quality assurance/quality control and sampling protocol

Sampling at Nak follows a rigorous methodology and internal QA/QC protocol. Drill core is halved on site, and samples are submitted to ALS Geochemistry in Langley, B.C., for preparation and analysis. ALS is accredited to the ISO/IEC 17025 standard for assays. All analytical methods include quality control standards inserted at set frequencies. The entire sample interval is crushed and homogenized, and 250 grams of the homogenized sample are pulped. All samples were analyzed for gold, silver, copper, molybdenum and a suite of 45 other major and trace elements. Analysis for gold is by fire assay fusion followed by inductively coupled plasma atomic emission spectroscopy (ICP-AES) on 30 grams of pulp. Analysis for silver, copper, molybdenum, and all other major and trace elements are analyzed by four-acid digestion followed by inductively coupled plasma mass spectroscopy (ICP-MS).

Internal QA/QC protocols dictate that individual core samples are no less than 70 centimetres and no greater than three metres in length. To control standard, blank and duplicate sample frequency and to better constrain pass/fail reanalysis intervals, samples are submitted to the lab in 50-sample batches. Within each 50-sample batch, there is one gold-copper standard and two coarse reject duplicates, inserted at regular intervals, and two blank samples, inserted sequentially following well-mineralized samples where possible, for a total of 10 per cent QA/QC samples. All gold and copper standard analyses from the 2024 program passed within three standard deviations of expected values. Where duplicate values differed significantly, the lower values from the resulting reanalyses were used.

About American Eagle's Nak project

The Nak project lies within the Babine copper-gold porphyry district of central British Columbia. It has excellent infrastructure through all-season roads and is close to the towns of Smithers, Houston and Burns Lake, B.C., which lie along a major rail line and Provincial Highway 16. Historical drilling and geophysical, geological and geochemical work at Nak, which began in the 1960s, tested only to shallow depths. Still, the work revealed a very large near-surface copper-gold system that measures over 1.5 kilometres by 1.5 kilometres. Drilling completed by American Eagle in 2022, 2023 and 2024 returned significant intervals of high-grade copper-gold mineralization that reached beyond and much deeper than the historical drilling, indicating that zones of near-surface and deeper mineralization, locally with considerably higher grades, exist within the broader Nak property mineralizing system. American Eagle Gold completed an aggressive 31,500-metre drill program in 2025 designed to expand and improve the mineral footprint; assays are currently being received.

About American Eagle Gold Corp.

American Eagle is dedicated to advancing its Nak copper-gold porphyry project in west-central British Columbia, Canada. The company benefits from over $25-million in cash, bolstered by two strategic investors formed in the past two years with Teck Resources and South32. With substantial financial and technical resources, American Eagle Gold is well positioned to drill, derisk and define the full potential of the Nak copper-gold porphyry project.
