• Initial direct capital costs are estimated at US$36 million, with total initial capital costs (including indirects and contingency) at US$55 million over the four-year pre-production period.
• Sustaining capital costs are estimated at US$38 million, and permitting and closure costs at US$4 million.
• The average life of mine operating costs is estimated at US$307.63 per ton milled.
• The Base Case after-tax Net Present Value (NPV) at an 8% discount rate is $31 million, with an Internal Rate of Return (IRR) of 14%, and a simple payback period of approximately 5.8 years from the start of production.
• The Alternative Case (Indicated only) after-tax NPV at an 8% discount rate is $18.7 million, with an IRR of 12.4%, and a simple payback period of approximately 5.7 years.
• A two-phase exploration program with a total budget of approximately US$2.2 million is recommended to advance the project, including delineation drilling and a Pre-Feasibility Study (PFS).

Sentiment

Score: 7

Explanation: The report presents a positive Preliminary Economic Assessment for the Bullfrog Project, demonstrating potential economic viability with solid NPV and IRR figures, supported by existing processing infrastructure. However, the reliance on Inferred Resources for the base case, the preliminary nature of the study (PEA level), and the need for significant further studies (PFS, geotechnical, hydrogeological) and permitting introduce considerable future risks and uncertainties. The high capital cost accuracy range (+/-50%) also suggests a need for more detailed engineering.

Positives

• The Preliminary Economic Assessment (PEA) demonstrates positive economics for both the Base Case (Indicated and Inferred Resources) and the Alternative Case (Indicated only), with an after-tax NPV(8%) of $31 million and IRR of 14% for the Base Case.
• The project is 100% owned by EFR, a US-based uranium and vanadium exploration and mine development company, ensuring full control over development.
• The Bullfrog Project will utilize the existing White Mesa Mill for processing, which is the only active uranium mill in the U.S., eliminating the need for new mill construction and leveraging proven processing methods.
• Historical metallurgical tests and mill production records confirm an expected 95% uranium recovery at the White Mesa Mill for similar mineralized material.
• The project is located in a region with a well-developed mining industry and is close to necessary infrastructure and resources, facilitating operations.
• Historical drill hole logging and sampling procedures meet industry standards and are deemed adequate for Mineral Resource estimation, with no significant disequilibrium issues expected to negatively affect uranium resource estimates.
• The project is situated in a regulatory jurisdiction with recent experience in permitting similar mining activities, potentially streamlining the approval process.
• Waste rock characterization indicates net-neutralization potential and is not expected to generate acid-mine drainage, reducing environmental liabilities.

Negatives

• The economic analysis is preliminary in nature (PEA level) and relies, in part, on Inferred Mineral Resources (approximately 20% of Base Case tonnage), which are geologically speculative and do not have demonstrated economic viability.
• There are no current Mineral Reserves estimated for the Project, indicating a lower level of confidence compared to a Feasibility Study.
• The initial capital cost estimate has a wide accuracy range of +50% / -50%, suggesting a high degree of uncertainty and potential for significant cost overruns.
• No geotechnical drilling has been completed for the Project, meaning mine design relies on assumptions about rock mass characterization, which could lead to unforeseen ground control challenges.
• Further hydrogeological modeling and analysis are required to confirm groundwater inflow estimates (expected 20-50 gallons per minute), which could impact dewatering costs and mine operations.
• No site-specific water quality data is available for the Bullfrog Project, making the need for water treatment during dewatering uncertain.
• The project is a 'Greenfield' site, meaning all mine infrastructure, including access roads, power, and surface facilities, needs to be developed from scratch.
• No long-term agreements for materials, supplies, or labor have been entered into yet, which could introduce procurement and cost risks.

Risks

• **Geological Speculation**: The economic analysis relies on Inferred Mineral Resources (20% of Base Case), which are geologically speculative and may not be converted to Mineral Reserves, impacting project economics.
• **Geotechnical Uncertainty**: Lack of site-specific geotechnical drilling data means mine design relies on assumptions; actual rock conditions could be worse than anticipated, impacting stability, ground support requirements, and costs.
• **Hydrogeological Risks**: Groundwater inflow estimates (20-50 gpm) require further modeling and analysis; higher inflows could significantly increase dewatering costs and impact mine productivity.
• **Permitting Delays**: Obtaining all necessary federal, state, and local regulatory approvals (e.g., Plan of Operation, Notice of Intention, air/water discharge permits) could be time-consuming and delay project development.
• **Social License**: Time and costs associated with obtaining and maintaining a 'social license' from Native American groups and other non-Indigenous stakeholders could affect project development and operations.
• **Capital Cost Accuracy**: The initial capital cost estimate has an accuracy of +/-50%, indicating significant potential for cost overruns that could impact project viability.
• **Operating Conditions Variability**: Productivities are based on average ground conditions and substantial depressurization; higher than expected groundwater inflows or weaker rocks could significantly reduce productivity and challenge production targets.
• **Uranium Price Volatility**: While a $90/lb U3O8 price is assumed, uranium prices are subject to market fluctuations and speculative investment, which could materially impact the project's economic viability.
• **Infrastructure Development**: The project requires significant new infrastructure development (access roads, power, water treatment, buildings), which carries inherent execution risks and potential for delays or cost increases.
• **Environmental Management**: Waste rock contains elevated levels of uranium, arsenic, selenium, and radium, requiring careful management to prevent leaching, although the arid climate is expected to mitigate this risk.

Future Outlook

The company plans a two-phase exploration program starting in 2025, with a total budget of approximately US$2.2 million, contingent on Phase 1 success. This program aims to conduct 20-30 drill holes to upgrade Inferred Resources to Indicated, utilizing Prompt Fission Neutron (PFN) logging for equilibrium analysis, and updating the Mineral Resource estimate. Following this, a Pre-Feasibility Study (PFS) will be completed, which will involve further development drilling, geotechnical and hydrogeology studies, updated mine plans, and investigation of alternative mining methods like roadheaders. The White Mesa Mill will continue intermittent operations, with plans to evaluate historical data for flowsheet improvements and conduct bench tests on Bullfrog material. Additionally, surface infrastructure design and cost estimation are planned for future mining activities.

Industry Context

The Bullfrog Project is strategically located within the Colorado Plateau, a historically significant uranium mining region. Its development benefits from leveraging Energy Fuels' White Mesa Mill, the sole active uranium mill in the U.S., which provides a critical and established processing solution. The project's economic projections are based on a long-term uranium price forecast of $90/lb, which aligns with industry expectations for sustained pricing, particularly under TradeTech's FAM 2 scenario, reflecting anticipated supply constraints and the restart of U.S. projects. This development is consistent with a broader industry trend of reactivating and initiating new uranium projects in response to evolving market dynamics and increasing global demand for nuclear power.

Comparison to Industry Standards

• The proposed mining methods (room and pillar, drift and fill, split-shot) are consistent with those employed by EFR at its other underground uranium operations (Pinyon Plain and La Sal mines), indicating adherence to established company and regional practices for tabular sandstone-hosted deposits.
• The White Mesa Mill, operational since 1981, utilizes an agitated hot acid leach and solvent extraction process, which is a proven and widely accepted method for uranium recovery, with historical metallurgical tests and production records confirming a high 95% recovery rate.
• The use of a $90/lb U3O8 price for Mineral Resource estimation and cash flow projections is considered reasonable and aligns with independent long-term market forecasts and industry practice for resource-level economic assessments.
• Environmental baseline studies and permitting efforts are being conducted in coordination with key federal and state agencies (BLM, Utah DOGM), demonstrating compliance with standard regulatory frameworks.
• The contingency allowance of 25% and capital cost accuracy of +/-50% are stated as a minimum level for a Preliminary Economic Assessment (PEA) stage project, which is typical for studies at this early stage of development.
