'We are still targeting to be in 1st production by the middle of 2028': Cates on Uranium Mine

Key Concepts

• In-Situ Recovery (ISR): A mining method that extracts minerals by dissolving them in place using a solution injected through boreholes, bypassing the need for traditional pits or shafts.
• SABRE (Surface Access Borehole Resource Extraction): A patented mining method developed by Denison Mines and Orano that allows for the excavation of rock from subsurface cavities via surface-drilled boreholes.
• U3O8: Triuranium octoxide, the most common form of yellowcake uranium traded on the market.
• Campaign Mining: A production strategy where mining operations are conducted in specific, intermittent phases rather than continuously.
• Athabasca Basin: A region in northern Saskatchewan, Canada, known for hosting some of the world's highest-grade uranium deposits.

1. Phoenix Project: Flagship Development

Denison Mines is currently focused on the construction of the Phoenix in-situ recovery (ISR) uranium mine in northern Saskatchewan.

• Status: The project has received all final permits as of February 2024. Site preparation and early works are underway.
• Timeline: The company is targeting first production by mid-2028.
• Strategic Advantage: CEO David Cates highlights that ISR is a "game changer" for construction timelines and costs. Because it does not require a conventional mill, tailings facility, or large-scale rock crushing/grinding infrastructure, the project is significantly more efficient than traditional mining operations.
• Significance: This is the first large-scale uranium mine approved for construction in Canada in over 20 years.

2. McLean Lake and SABRE Mining

Denison operates a joint venture at McLean Lake with Orano, a global leader in the nuclear fuel cycle.

• SABRE Methodology: This patented technology allows for the extraction of ore from subsurface cavities without the need for a shaft or open pit.
• Operational Status: The mine achieved commercial production in the second half of 2023. Operations are currently in a "campaign mining" phase, with early 2024 focused on resource confirmation drilling. The company aims to transition to continuous mining over the coming years.

3. Financial Strategy and Uranium Holdings

Denison Mines maintains a robust balance sheet by holding physical uranium, which serves as a strategic asset for financing the Phoenix project.

• Inventory: As of the end of Q1, the company held approximately 1.85 million pounds of U3O8.
• Monetization: The company acquired much of this inventory in 2021 at under $30/lb. They are now selling portions of this stock to fund construction.
• Performance: In Q1, Denison sold 550,000 pounds at approximately $99/lb, significantly higher than the spot price (which was in the mid-$80s at the time of the interview), demonstrating a "savvy" approach to market timing.

4. Growth and Exploration Strategy

Beyond its own projects, Denison employs an "amplification" strategy to increase its exposure to uranium discovery:

• Cosa Resources: Denison holds a ~20% stake and acts as a direct partner on properties like Murphy North and Darby.
• Strategic Investments: The company maintains stakes in Sky Harbor Resources (adjacent to the Wheeler River property) and Foremost Clean Energy (which has an option on 10 of Denison’s properties in the Athabasca Basin).

5. Corporate Governance and Board Rejuvenation

Denison has undergone a board rejuvenation program to attract high-caliber expertise:

• Key Appointments:
  • Wes Carson: Senior executive at Wheaton Precious Metals.
  • Ken Hartwick: Recently retired CEO of Ontario Power Generation.
  • KHNP Representative: An appointee from Korea Hydro Nuclear Power, one of Denison’s largest shareholders and a major operator of South Korean nuclear plants.

Synthesis and Conclusion

Denison Mines is currently in a capital-intensive investment phase, transitioning from an exploration and development company to a producer. By leveraging the ISR mining method for the Phoenix project and the SABRE method at McLean Lake, the company is bypassing traditional, high-cost mining infrastructure. Their financial strategy—monetizing low-cost uranium inventory at current high market prices—provides the necessary liquidity to fund the Phoenix construction. With a clear path to production by 2028 and a board bolstered by nuclear industry veterans, Denison is positioning itself as a significant player in the Canadian uranium sector.
