8-K: Energy Fuels Inc. Reports Record Uranium Mining Rates and High-Grade Drill Results at Pinyon Plain Mine

Energy Fuels Inc. announced record uranium mining rates at its Pinyon Plain mine in April 2025 and reported significant high-grade uranium mineralization from its underground drill program.

Summary

• Energy Fuels Inc. reported record uranium mining rates at its Pinyon Plain mine in Arizona during April 2025.
• The company mined 4,604 tons of ore, containing approximately 151,400 pounds of uranium with an average grade of 1.64% eU3O8.
• Production rates have steadily increased over the past several months, with April's results representing the largest monthly production rate since mining began last year.
• The company believes it will mine considerably more uranium from the Main Zone of the deposit than described in the February 2023 Pre-Feasibility Study.
• Drill results from the 2024-2025 underground drill program in the Juniper Zone show numerous additional high-grade intercepts.
• The February 2023 PFS includes a Mineral Resource estimate for the Juniper Zone of 703,000 pounds of eU3O8 at an average grade of 0.95% contained in 37,000 tons of Indicated Mineral Resources.
• Highlights from the drilling program include intercepts such as 13.4 ft with an average grade of 7.02% eU3O8 (PPCH-028) and 7.5 ft with an average grade of 7.50% eU3O8 (PPCH-029).
• The company is planning to conduct additional drilling in the Juniper Zone as it continues development of that area.
• The Pinyon Plain mine is a 'breccia pipe' deposit containing large quantities of 'natural uranium'.
• Energy Fuels processes ore from Pinyon Plain and other mines into natural uranium concentrates (U3O8) at its White Mesa Mill in Utah.

Sentiment

Score: 8

Explanation: The document presents positive news regarding production and exploration results, suggesting a favorable outlook for the company. The high grades and increased production rates are likely to be viewed positively by investors.

Positives

• Record uranium mining rates were achieved at the Pinyon Plain mine.
• High-grade uranium mineralization was identified in the Juniper Zone through drilling.
• The company anticipates mining more uranium than initially projected.
• The White Mesa Mill provides a processing solution for the mined ore.

Risks

• The document contains forward-looking statements that are subject to various risks and uncertainties.
• These risks include commodity price fluctuations, engineering and mining difficulties, permitting delays, regulatory changes, and competition from other producers.
• Actual results may differ materially from the forward-looking statements.

Future Outlook

The company plans to conduct additional drilling in the Juniper Zone and may update the S-K 1300/NI 43-101 Technical Report for the Pinyon Plain mine later this year.

Industry Context

This announcement positions Energy Fuels as a key player in the U.S. uranium mining sector, particularly as demand for nuclear energy and domestic uranium supply increases. Other companies in the uranium mining sector include Cameco, Uranium Energy Corp, and Denison Mines. The high grades reported could give Energy Fuels a competitive advantage.

Comparison to Industry Standards

• The reported grades of up to 7.50% eU3O8 in the Juniper Zone are significantly higher than the average grades of many uranium deposits globally.
• For example, the Cigar Lake mine, operated by Cameco, is known for its high-grade uranium, but these results suggest Pinyon Plain could be comparable in certain zones.
• The average grade of uranium mines globally is typically below 1% U3O8, making the 1.64% eU3O8 average grade mined in April at Pinyon Plain a strong result.
• The planned updated Technical Report will provide a more detailed comparison to industry benchmarks.

Stakeholder Impact

• Shareholders may benefit from increased production and potential resource expansion.
• Employees may benefit from continued operations and potential job security.
• Customers (nuclear utilities) may benefit from a reliable supply of uranium concentrates.

Next Steps

• Conduct additional drilling in the Juniper Zone.
• Sample and analyze drill core.
• Potentially update the S-K 1300/NI 43-101 Technical Report for the Pinyon Plain mine.
