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

Rhea-AI Summary

American Eagle (OTCQB: AMEGF, TSXV: AE) reports step-out drilling that expands the South Zone and confirms continuity of a high-grade core. NAK25-80 returned 618 m at 0.77% CuEq from surface. Step-outs extend the corridor ~750 m east and ~500 m south, leaving the system open for further growth.

Company also highlights prior long intervals (e.g., NAK25-78: 802 m of 0.71% CuEq) and district-scale continuity following Feb 25 results.

Positive

• 618 m @ 0.77% CuEq from surface in NAK25-80
• South Zone corridor extended ~750 m east and ~500 m south
• NAK25-73: 1,033 m @ 0.25% CuEq from surface, demonstrating broad footprint
• Supports district-scale thesis when paired with NAK25-70's 901 m @ 0.43% CuEq reported Feb 25
• High-grade core continuity confirmed linking at-surface gold-rich zones to deeper copper-rich intervals

Negative

• Reported assays are uncapped, which may inflate long-interval averages
• True thickness of intervals is not defined due to drill intercept reporting
• CuEq calculations assume specific metal prices and 80% recoveries, adding valuation uncertainty
• No formal mineral resource or reserve estimate reported yet

Highlights:

• 618 m of 0.77% CuEq 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% CuEq from surface, and strengthens confidence in thickness and continuity of the South Zone mineralization.

• Material step-out growth: NAK25-73/75/79/80 extend the South Zone corridor ~750 m east and ~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.

Toronto, Ontario--(Newsfile Corp. - February 27, 2026) - American Eagle Gold Corp. (TSXV: AE) (OTCQB: AMEGF) (the "Company" or "American Eagle") reports new drill results from its 100%-owned NAK Project that further de-risk and expand the South Zone while reinforcing NAK's emerging district-scale growth profile. These results follow the Company's February 25, 2026 release, which demonstrated continuous stock-hosted mineralization over a 1.7 km east-west trend, complementing this significant expansion by further extending mineralization over 500 m south of the Babine porphyry stock.

Hole NAK25-80 delivered a standout interval of 618 m averaging 0.77% copper equivalent (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% CuEq from surface).

Importantly, step-out 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 ~750 m eastward from the South Zone/Main Zone area, and ~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 February 25 district-scale breakthrough, highlighted by NAK25-70's 901 m of 0.43% 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 g/t Au, 0.14 % Cu). Below 142 m, and down to a depth of 659 meters, the hole intersected sandstone and conglomerate that were intruded by mafic dykes, 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.

* Copper Equivalent (CuEq) shown in Tables for drill intercepts are calculated on the basis of US$ 4.50/lb for Cu, US$ 3,375/oz for Au, US$ 60/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 x 1%]) + (Ag grade in g/t x (Ag recovery / Cu recovery) x [Ag price ÷ 31] / [Cu price x 2200 x 1%] + (Mo grade in % x (Mo recovery / Cu recovery) x [Mo price] / [Cu price]). The assays have not been capped. The reported intervals represent drill intercepts, and insufficient data are available at this time to state the true thickness of the mineralized intervals.

South Zone Eastern Expansion

The additional holes in this release, NAK25-73, -75, and -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% 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 dykes of a variety of compositions. NAK25-79 was collared 320 meters southeast of NAK25-73 and was drilled to the southwest. It intersected sporadic copper mineralization that increased substantially in tenor below 400 meters, extending the mineralization in that area over 500 meters 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.

QA/QC 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, British Columbia 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 g of the homogenized sample is 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 g of pulp. Analysis for silver, copper, and 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 cm and no greater than 3 m in length. To control standard, blank, and duplicate sample frequency, and to better constrain pass/fail re-analysis 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% QA/QC samples. All gold and copper standard analyses from the 2024 program passed within 3 standard deviations of expected values. Where duplicate values differed significantly, the lower values from the resulting re-analyses 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 1960's, tested only to shallow depths. Still, the work revealed a very large near-surface copper-gold system that measures over 1.5 km x 1.5 km. 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.

FAQ

What did American Eagle (AMEGF) report for NAK25-80 on February 27, 2026?

NAK25-80 returned 618 m averaging 0.77% CuEq from surface, a continuous high-grade interval. According to the company, this links near-surface gold-rich mineralization to a deeper copper-rich core and reinforces South Zone continuity.

How far did AMEGF extend the South Zone with the February 27, 2026 drill results?

Drilling extended the South Zone corridor roughly 750 m to the east and 500 m to the south. According to the company, step-outs NAK25-73/75/79/80 trace a connected corridor along the porphyry margin.

What other long intervals did American Eagle cite alongside NAK25-80 (symbol AMEGF)?

The company references prior long intercepts such as NAK25-78: 802 m @ 0.71% CuEq and Feb 25's NAK25-70: 901 m @ 0.43% CuEq. According to the company, these support a larger mineralized envelope.

What limitations did American Eagle note about the reported CuEq figures for AMEGF?

CuEq values use assumed metal prices and 80% metallurgical recoveries, and assays are uncapped. According to the company, these assumptions introduce uncertainty until metallurgical and resource work is completed.

Does the February 27, 2026 release establish a mineral resource for AMEGF at NAK?

No formal mineral resource or reserve was reported in this release. According to the company, additional data are required to determine true thickness and to support a resource estimate.
