Sponsored: Arizona Eagle drills beyond McCabe

Key Concepts

• Mesothermal Deposit: A type of mineral deposit formed at intermediate depths and temperatures, typically associated with structural deformation and mountain-building events.
• Laramide Orogeny: A period of mountain building in western North America (Cretaceous period) that created the structural stress responsible for many precious metal deposits.
• Cutoff Grade: The minimum grade of ore required to make mining economically viable; lowering this threshold can significantly increase the size of a mineral resource.
• Reverse Takeover (RTO): A process where a private company acquires a public company to gain access to the public market.
• Head Grade: The concentration of metal in the ore as it is extracted from the mine, before processing or milling.
• VMS (Volcanogenic Massive Sulfide): A type of metal sulfide ore deposit created by volcanic-associated hydrothermal events.

1. Project Overview and Strategic Context

Arizona Eagle Mining is transitioning to the public market via a reverse takeover with Core Nickel. The company’s primary asset is the Eagle project, centered on the historic McCabe mine in Yavapai County, Arizona.

• Historical Significance: The McCabe mine is a past producer with a history spanning 150 years. It was last active in the mid-1980s to early 1990s, closing primarily due to corporate acquisition by BHP and low gold prices at the time.
• Strategic Advantage: The project is located on over 300 acres of private land, accessible via a paved highway, and situated in a mining-friendly jurisdiction with local infrastructure and talent.

2. Geological Potential

The project is characterized by a mesothermal precious metals system formed during the Laramide Orogeny.

• Structural Complexity: The primary "McCabe structure" runs northeast-southwest. The company has identified multiple parallel structures across the land package that show surface-level gold, silver, and copper mineralization.
• Depth Potential: While historical mining only reached depths of approximately 150–200 feet (with the Sooner shaft reaching 1,450 feet in the 1980s), mesothermal systems are known to extend to depths of several kilometers. The company views the current exploration as having barely scratched the surface.

3. Economic Drivers and Resource Upside

CEO Kevin Reed emphasizes that "grade is king," noting that the project’s high-grade nature provides a significant competitive advantage.

• Historical Resource vs. Modern Economics: The historical resource estimate was calculated using a 6.8 g/t cutoff grade in a $300/oz gold environment.
• Expansion Opportunity: By applying modern economic standards (where underground mines often use a 2 g/t cutoff), the company believes a significant amount of gold previously excluded from the resource estimate can now be considered viable.
• Head Grade: The historical resource grade is nearly 12 g/t, with an estimated head grade of 15 g/t, placing it in the upper echelon of global deposits.

4. Operational Framework and Methodology

• Exploration Strategy: The company is currently executing a fully funded 4,500-meter drill program. This is supported by ongoing Induced Polarization (IP) surveys and surface sampling to identify new targets along the parallel structures.
• Jurisdictional Benefits: Operating on private ground (rather than Bureau of Land Management or National Forest land) simplifies the permitting process, though the company remains committed to standard environmental compliance regarding air and water quality.
• Infrastructure: The site includes existing shafts (McCabe, Sooner, and Gladstone) and is located just 10 minutes from a town with a deep-rooted mining history, reducing logistical costs compared to remote projects in regions like Nunavut or the Andes.

5. Notable Quotes

• "Grade is king, and we have grade." — Kevin Reed, on the project's primary competitive advantage.
• "We’ve got over 300 [acres of private ground] which is really advantageous for exploration, but also when it comes to surface disturbance and putting a mine into production." — Kevin Reed, highlighting the operational flexibility of the land package.

6. Synthesis and Conclusion

Arizona Eagle Mining is positioning itself as a high-grade, low-risk developer by leveraging a historic, well-located asset in a mining-friendly jurisdiction. The core thesis rests on the belief that modern exploration and a lower economic cutoff grade will reveal a much larger resource than historical data suggests. With a fully funded drill program and a transition to the public market, the company is focused on proving the depth and strike potential of the McCabe structure and its parallel systems to unlock significant shareholder value.
