American Eagle Extends South Zone Discovery by over 300 Metres; Returns 91 m of 1.53% CuEq Within 167 m of 1.06% CuEq

American Eagle Gold announced drill results from its NAK Copper-Gold project in British Columbia on December 11, 2025. The results are from the ongoing 30,000-metre drill program and focus on the South Zone discovery.

Key intercepts include: - NAK25-57: 909 metres of 0.41% Copper Equivalent (CuEq) from surface. - Including a higher-grade core of 167 metres of 1.06% CuEq. - Within that core, a very high-grade section of 91 metres of 1.53% CuEq was intersected. - NAK25-52: 843 metres of 0.23% CuEq from surface. - Including 85 metres of 0.92% CuEq.

The drilling has successfully extended the South Zone by over 300 metres, defining a mineralized footprint with an east-west strike of approximately 500 metres. The zone remains open along strike and at depth. The company also noted a cash position of C$36 million.

The latest drill results are materially positive and continue to confirm the thesis that the NAK project hosts a large, bulk-tonnage copper-gold system with a significant, high-grade core.

• Confirmation of High-Grade Core: The highlight interval of 91 metres at 1.53% CuEq is exceptionally strong for a porphyry system. It builds upon previous high-grade intercepts, such as the 77 metres of 1.78% CuEq reported on October 7, 2025. This consistency in hitting high grades at depth demonstrates continuity and significantly de-risks the geological model for the South Zone.
• Scale and Expansion: Extending the South Zone's strike length by over 300 metres to a total of 500 metres is a crucial step in building the potential tonnage for a future resource estimate. The system remains open, suggesting further growth potential. The long intercepts from surface (909 m in NAK25-57) reinforce the project's bulk tonnage potential.
• Alignment with Expectations: The December 1, 2025 release guided that South Zone results were expected within two weeks, and the company has delivered. The results exceed the grade of the broad intervals reported on December 1 (e.g., 911 m of 0.30% CuEq) and confirm the CEO's commentary about the South Zone becoming an "expanding center of gravity."
• Market Context: While the results are excellent, they must be viewed in the context of the stock's performance. The share price is currently trading significantly below the C$0.875 price paid by strategic investor South32 in late 2024. The latest news provides fundamental validation that could help close this valuation gap, but the market has previously sold off on strong news (January 14, 2025), indicating a potential "show me" sentiment.

Overall, this news materially enhances the value proposition of the NAK project by adding grade, scale, and confidence. It is a significant step forward in advancing the project towards an initial resource estimate.

American Eagle Gold Corp. is a Canadian mineral exploration company focused on advancing its flagship NAK Copper-Gold Porphyry Project. The project is located in the Babine copper-gold porphyry district of central British Columbia, a mining-friendly jurisdiction with excellent infrastructure. The NAK project is a large, near-surface copper-gold system measuring over 1.5 by 1.5 kilometres. The company's strategy is to systematically drill and expand the known zones of mineralization to define a significant resource.
