Capitalizing on Strong Uranium Pricing:

• Due to uranium market tailwinds and upcoming commitments in long-term contracts with U.S. nuclear utilities, the Company is currently mining and stockpiling uranium ore from its Pinyon Plain, La Sal and Pandora mines and plans to ramp up to a production run-rate of approximately 1.1 to 1.4 million pounds of U₃O₈ per year by late-2024.

• The Company expects to produce a total of 150,000 to 200,000 pounds of finished U₃O₈ during 2024 from stockpiled alternate feed materials and newly mined ore, which is at the lower end of our previous guidance of 150,000 to 500,000 pounds of finished U₃O₈ during 2024, due to delays in transporting ore from the Pinyon Plain mine to the White Mesa Mill, which is expected to be resolved in Q4-2024. Mining continues at the Pinyon Plain mine, with mined ore being stockpiled at the mine site, containing approximately 180,000 pounds of U₃O₈ at September 30, 2024, which is expected to be processed at the Mill later in 2024 or in early 2025.

• During Q3-2024, the Company received positive results from drill holes during ongoing preparations at its Nichols Ranch in situ recovery ("ISR") Project in Wyoming. Both the Nichols Ranch Project and Whirlwind Mine in Colorado are being prepared for production and are within one year of a "go" decision, as market conditions warrant. Production from these mines, when combined with alternate feed materials, uranium from monazite, and 3^rd party uranium ore purchases, would be expected to increase the Company's production run-rate to roughly two million pounds per year by as early as 2026.

• The Company continued advancing permitting and other pre-development activities on its large-scale Roca Honda, and Bullfrog uranium projects in Q3-2024, which together with its Sheep Mountain Project, have the potential to expand the Company's uranium production to a run-rate of up to five million pounds of U₃O₈ per year in the coming years.

• As of October 28, 2024, the spot price of U₃O₈ was $81.00 per pound and the long-term price of U₃O₈ was $82.00 per pound, according to data from TradeTech.

Rare Earth Element Production Milestones:

• The Company produced about 38 tonnes of separated NdPr from its newly commissioned Phase 1 REE separation circuit at the Mill in Q2- and Q3-2024.

• Samples of the Company's NdPr product have been sent to permanent magnet and other companies around the world for product qualification, and initial testing responses have been positive.

• The Company is currently in the process of updating the White Mesa Mill's AACE International ("AACE") Class 4 Pre-Feasibility Study (not a Pre-Feasibility Study subject to or intended to be compliant with NI 43-101 or S-K 1300), originally released in Q2-2024 to increase throughput to a total of 60,000 tpa of monazite, producing roughly 6,000 tpa of NdPr, 150 to 225 tpa of Dy, and 50 to 75 tpa of Tb, of which the existing commissioned Phase 1 circuit will constitute about 17% of this amount (10,000 tpa of monazite). The Mill PFS referenced above can be viewed on the Company's website, www.energyfuels.com.

Heavy Mineral Sands:

• On October 2, 2024, the Company announced it completed its previously announced acquisition of all the issued and outstanding shares of Base Resources Ltd. ("Base Resources"), which is expected to transform the Company into a global leader in critical minerals production, including HMS (titanium and zirconium), REEs and uranium. The acquisition of Base includes the advanced, world-class Toliara HMS project in Madagascar. In addition to its stand-alone, ilmenite, rutile (titanium) and zircon (zirconium) production capability, the Toliara Project also contains a long-life, high-value and low-cost monazite (REEs) stream, produced as a byproduct of primary titanium and zirconium production. Toliara's monazite is expected to be processed at the Mill into separated REE products, along with uranium, at globally competitive capital and operating costs. The Toliara Project is subject to negotiation of fiscal terms with the Madagascar government and the receipt of certain Madagascar government approvals and actions before a current suspension on activities at the Toliara Project will be lifted and development may occur. The transaction also includes Base's management, mine development and operations teams, who have a successful track-record of designing, constructing, and profitably operating a world-class HMS operation in Kenya.

• The Company continued to advance the Donald Project (the "Donald Project"), a large monazite-rich HMS project in Australia, pursuant to its joint venture with Astron Corporation limited, announced in Q2-2024. The Company expects that a final investment decision ("FID") will be made on the Donald Project as early as 2025.

• During Q3-2024, the Company also continued to advance its wholly owned Bahia HMS project in Brazil (the "Bahia Project") with its Phase 2 drilling campaign, which is expected to continue through the rest of the year. Additionally, the Company completed bulk test work on a 2.5 tonne sample in March 2024, and recently shipped a larger 15 tonne sample to the U.S. for additional process test work. The Company expects to complete a U.S. Subpart 1300 of Regulation S-K ("S-K 1300") and Canadian National Instrument 43-101 ("NI 43-101") compliant mineral resource estimate on the Bahia Project during 2024.

Vanadium Highlights:

• The Company chose not to execute any vanadium sales during Q3-2024 and holds about 905,000 pounds of V₂O₅ in inventory.

• As of October 28, 2024, the spot price of V₂O₅ was $5.25 per pound, according to data from Fastmarkets.

Medical Isotope Highlights:

• On August 19, 2024, the Company announced it acquired RadTran LLC ("RadTran"), a private company specializing in the separation of critical radioisotopes, to further the Company's plans for development and production of medical isotopes used in cancer treatments. RadTran's expertise includes separation of radium-226 ("Ra-226") and radium-228 ("Ra-228") from uranium and thorium process streams. This acquisition is expected to significantly enhance Energy Fuels' planned capabilities to address the global shortage of these essential isotopes used in emerging targeted alpha therapies ("TAT") for cancer treatment.

• The Company continues to utilize its research and development ("R&D") license for the recovery of R&D quantities of Ra-226 at the Mill. Activities to set up the pilot facility at the Mill continued in Q3-2024 and are expected to progress through the end of the year, with the goal of producing R&D quantities of Ra-226 for testing by end-users of the product in late 2024 or early 2025.

Mr. Chalmers continued:

"During the quarter, we achieved numerous additional milestones to bring the Energy Fuels' vision to fruition for our innovative, low-cost, U.S.-centered critical mineral supply chain. As previously announced, shortly after the close of the quarter, we successfully completed our acquisition of Base Resources. This is a major piece of our strategic puzzle, bringing to the Company the Base Resources management and operations team and the world-class Toliara Project in Madagascar, which is considered by industry experts to be one of the best HMS projects in the world. With the Toliara Project, our joint venture on the Donald Project in Australia, and our 100% ownership of the Bahia Project, we have secured a leading position in the titanium and zirconium mineral industry, in addition to a low-cost source of REE feedstock that will be processed in the United States.

"These developments have the potential to transform Energy Fuels into a world leader in titanium, zirconium, and rare earth elements production, while maintaining our position as a U.S. leader in uranium and vanadium production. All these materials are critical to the global energy transition and to our vision of creating a leading diversified critical minerals company."
