The option agreement includes 23 mineral claims and one claim application totalling 6,690 hectares with the Eagle Plains claims representing approximately 72% of American Eagle's 9,283-hectare district scale land position in the Babine, one of the largest and most strategic land positions in the core of one of British Columbia's most active porphyry camps. The claims are owned 100% by Eagle Plains, with no underlying royalties or encumbrances.

The properties are less than 2 km from the Morrison and Hearne Hill deposits, highlighting the significant regional and local potential to host Cu-Au porphyry-type mineralization. The properties can be accessed by truck utilizing a network of forest service roads from Highway 118 at Topley Landing, which are primarily used to service the past producing mines and active logging operations in the area.

Eagle Plains CEO, Charles Downie, commented: "We are excited to partner with American Eagle to explore one of British Columbia's premier copper-gold porphyry districts. The Hearne Hill South project was identified by American Eagle as the most compelling untested opportunity in the Babine camp, with the right geology, supportive geophysics, and virtually no drilling. American Eagle's stellar track record, including exploration success at the NAK, the ability to attract strategic investors like Teck, South32, and Eric Sprott, and a commitment to First Nations and Community relations, in conjunction with $50 million in cash in their treasury, make them the ideal partner to make new discoveries. Using a systematic, low-cost exploration approach to advance the Hearne Hill South Project and attract American Eagle as a partner, once again validates Eagle Plains' project generator model.".

Transaction Summary

To exercise the Option, American Eagle must make a series of cash payments and share issuances to Eagle Plains and fund exploration expenditures on the Project. These payments, share issuance and expenditures are separated into two phases, with the First Option entitling the Company to acquire a 60% interest in the Project by paying CA$400,000, issuing an aggregate of 1,200,000 common shares to EPL and funding CA$4,850,000 in exploration expenditures on the Project over a six-year term. Pursuant to the Second phase of the Option, the Company may acquire an additional 20% interest in the Project (for an 80% total interest) by notifying Eagle Plains of its intent to increase its interest to 80% and making an additional one-time payment of CA$1,000,000 cash, of which half may be paid in American Eagle shares valued at the 10-day VWAP at the time of notification. As part of the option agreement, American Eagle will reimburse Eagle Plains for the 2026 field program at Hearne Hill South.

If the First Option or the Second Option is exercised, a 2% smelter returns royalty will be granted to Eagle Plains over the entire property, 1% of which may be repurchased for CA$2,500,000. Following the exercise of the First or Second Option by the Company, Eagle Plains and American Eagle will form a joint venture which will administer the continued exploration and operation of the Project. American Eagle will serve as Operator during the term of the Agreement and TerraLogic Exploration Inc. will serve as geoscience consultant for all pre-drilling exploration.

The transaction is subject to TSX Venture Exchange acceptance.

Geology of Hearne Hill South

Like the NAK, Duke and Morrison properties, Hearne Hill South lies within the Babine Porphyry Belt, which is underlain primarily by Upper Triassic Takla Group and Lower Jurassic Hazelton Group volcanic and sedimentary rocks that along with younger volcano-sedimentary sequences such as that at NAK are cut by Cretaceous and Tertiary intrusions. In the Babine District, Eocene intrusions of the Babine Igneous Suite are the main drivers and common hosts for mineralization at NAK, Bell, Granisle, and Morrison, and thus remain the most prospective rocks in the search for porphyry copper-gold mineralization.

Mineralization in the area occurs in two principal forms: (1) stockwork porphyry copper-gold-silver-molybdenum mineralization associated with biotite-feldspar porphyry ("BFP") intrusions, which are typical of many mineralized occurrences in the Babine district; and (2) closely associated and commonly higher-grade copper-gold breccia pipes of the type which form the core of the Hearne Hill porphyry deposit, which lies immediately southeast of Morrison. The BFP intrusions and, to varying degrees, their stratified wall rocks, host chalcopyrite, pyrite, bornite, and minor molybdenite in quartz veins and veinlets, fracture fills, and disseminations, with potassic alteration (biotite, magnetite, potassium feldspar) associated with the best grades. These styles of mineralization are directly analogous to those identified in core logging by American Eagle's geologists at NAK.

Hearne Hill South and Jinx: Work to Date and Work Going Forward

Eagle Plains has completed substantial first-pass work at Hearne Hill South, including a 2025 field program. This work included a 286 line-kilometre high-resolution airborne magnetic survey, more than 32 line-kilometres of closely spaced soil geochemical sampling, and prospecting that returned copper-mineralized rock samples. These early results indicate that the property hosts underexplored geophysical and geochemical anomalies consistent with the porphyry copper exploration model, yet it has seen no modern drilling. Farther south, the Jinx claim group represents a very compelling early-stage porphyry target. First-pass surface work has identified gold-in-till with grain morphology that suggests a proximal bedrock source, along with a float sample that returned copper and gold values at porphyry tenors. Targeted geophysical surveying and systematic traverses to identify outcrop and complete additional surface sampling will aim to advance this claim group to drill-ready-status.

American Eagle's 2026-2027 program will include compilation of existing exploration data coupled with 3D inversion analysis of the property-wide magnetic data integrated with the Company's district-scale datasets from NAK. These programs will lead to fieldwork including infill soil geochemistry, prospecting, geological mapping, and ground geophysical surveying across priority anomalies, with the aim of defining drill targets.

First Nations, Community and Strategic Support

The American Eagle land package lies within the traditional territory of the Lake Babine Nation (LBN), where American Eagle has operated at NAK since 2022 under an Exploration Agreement that has since been expanded and updated three times, providing for respectful engagement, cooperative planning, and mutual benefit. The Company's established relationships with the LBN, provincial authorities, local contractors, and the communities of Smithers, Houston, and Burns Lake represent a competitive advantage, and American Eagle looks forward to engaging with the LBN on exploration plans across the expanded position. The expansion of its land position was undertaken with the knowledge and support of the Lake Babine Nation and the Company's strategic investors and is consistent with the collaborative approach the Company and the LBN have taken since 2022.
