Future Outlook

enCore Energy plans to continue its ramp-up strategy for wellfield expansion at Alta Mesa every 4 to 5 weeks, expecting extraction to steadily increase through 2025 and beyond. The Upper Spring Creek Project is slated to provide satellite feed for the Rosita CPP in 2026. Future projects in enCore's planned pipeline include the Dewey-Burdock project in South Dakota and the Gas Hills project in Wyoming.

Management Comments

• "The continued improvements in our rate of uranium extraction and advancement of wellfield development are truly a result of a top performing team focused on extraction and streamlined operations." William M. Sheriff, Executive Chairman.
• "We have always recognized the depth of experience and strength of our team, and their expertise is being clearly demonstrated during this ongoing ramp up phase." William M. Sheriff, Executive Chairman.
• "I also want to take this opportunity to commend the Texas Legislature for the passage of bills, and Governor Abbott for signing the legislation, which streamlined the permitting process for production area development and waste disposal wells." William M. Sheriff, Executive Chairman.

Industry Context

This announcement highlights enCore Energy's progress in the uranium mining sector, particularly within the In-Situ Recovery (ISR) method, which is gaining traction for its lower environmental impact compared to conventional mining. The commendation of Texas for its nuclear energy strategy and streamlined permitting reflects a broader trend of increasing governmental support for nuclear power as a clean energy source, potentially benefiting domestic uranium producers like enCore. The company's focus on expanding production aligns with global efforts to secure stable uranium supplies amidst growing demand for nuclear energy.

Comparison to Industry Standards

• The document does not provide specific comparable companies, projects, or results to global benchmarks.
• The stated operating capacity of the Alta Mesa CPP at 1.5 million pounds of uranium per year, with an additional 0.5 million pounds of drying capacity, positions it as a significant producer in the U.S. ISR uranium market.
• The historical production of nearly 5 million pounds between 2005 and 2013 demonstrates its proven capability.
• The current extraction rates, peaking at 3,705 pounds per day, indicate a strong ramp-up phase, which is critical for new or restarted ISR operations to achieve economic viability and scale.
• The 70/30 joint venture with Boss Energy Limited is a common industry practice for sharing risks and expertise in large-scale projects.
