Nuclear Fuels Releases Technical Report for the Kaycee Uranium Project

Exploration Target Identified of 11.5 to 30 Million Pounds

VANCOUVER, Oct. 8, 2024 - Nuclear Fuels Inc. (CSE: NF) (OTCQX: NFUNF) ("Nuclear Fuels" or the "Company") today released a NI 43-101 Technical Report for the Kaycee In-Situ Recovery ("ISR") Uranium Project located in Wyoming's Powder River Basin. The Technical Report, prepared by WWC Engineering, has identified an exploration target of 11.5 to 30 million pounds of uranium ("U₃O₈") supported by available historical data from previous operators and recent exploration recently conducted by Nuclear Fuels.

Significant highlights of the Technical Report include:

• An exploration target of 11.5 to 30 million pounds uranium ("U₃O₈) at average grades of 0.06% to 0.10%;
• A more extensive, in-depth review of historical data identified approximately 430 miles of roll fronts, an increase from the +110 miles previously outlined. Approximately 10% of the mapped redox trends have been explored with close-spaced drilling;
• The identification of the presence of multiple stacked roll fronts in each of the three stratigraphic formations that are known to host uranium mineralization;
• Indication the uranium mineralization lying under the water table may be amenable to In-Situ Recovery ("ISR"), based on historical metallurgical and mineral processing test work. ISR is an economical and environmentally responsible means of extracting uranium through wellfield technology and the use of oxygenated water, eliminating the use of conventional mining techniques;
• Details regarding the eleven (11) reported areas of historical uranium resources occurring at depths that range from less than 50 to 1,300 feet with a shallow water table typically lying between 50 and 250 feet.
• The Technical Report recommended that the Company should continue the current drilling program to delineate mineralization and explore for additional mineralized areas on the Project. In addition, the Technical Report recommended that the Company should prepare a classified mineral resource estimate for the Project, contingent on positive results of the drilling program.

Greg Huffman, Chief Executive Officer, stated: "We are experiencing a nuclear renaissance and significantly increased uranium activity in the region, including the announced planned restart of the ISR operations immediately to the east of Kaycee Project. The Kaycee Technical Report provides an exploration target which potentially represents a new uranium resource in Wyoming's prolific Powder River Basin. The Technical Report, combined with encouraging results from our ongoing drill program, increases our confidence that the Kaycee project has the potential to emerge as another uranium development project in the Powder River Basin."

Methodology to estimate an exploration target range based on historical data includes:

• Average grade and thickness for the mineralized zones in the Wasatch and Fort Union formations were calculated based on the historical data;
• Grade-Thickness calculated as weighted averages based on the number of drillholes in the various mineralized zones. Grade Thickness ("GT"), is defined as the product of the uranium grade (U₃O₈%) multiplied by the thickness of the intercept (in feet). In the Powder River Basin of Wyoming, potentially ISR- recoverable uranium mineralization with a GT of greater than 0.20 is considered suitable for inclusion in a potential wellfield;
• Outlines of the historically mapped mineralized areas were digitized with the area and length of the mineralized zones calculated;
• The average width of the mineralized zones was established by dividing the area of the mineralized zones by their length;
• The average width for each formation was multiplied by the length of the roll front trends to estimate the total area of mineralized trend for each formation;
• Mineralization does not occur along the entire roll front trend; therefore, a Trend Mineralization Factor was calculated for the Wasatch and Fort Union formations by dividing the length of the historically mapped mineralized zones by the total roll front trend length for each mineralized zone;
• The weighted average GT and Trend Mineralization Factor for the Wasatch and Fort Union formations was used for the purposes of calculating an exploration target in the Lance Formation.

Kaycee Uranium Project, Wyoming

The Kaycee Project in Wyoming's Powder River Basin ("PRB"), Nuclear Fuels' priority project, consists of over 55 square miles of mineral rights over a 36-mile mineralized trend hosting approximately 430 miles of identified roll fronts. The Kaycee Project is believed to be the only project in the PRB where all three known historically productive sandstone formations (Wasatch, Fort Union, and Lance) are mineralized and potentially accessible for ISR extraction. The Kaycee Project, under Nuclear Fuels, represents the first time since the early 1980's that the entire district is controlled by one company.

In 2023, Nuclear Fuels acquired the Kaycee Project from enCore Energy Corp., which retains a back-in right for 51% of the project by paying 2.5X the exploration costs and financing the Kaycee project to production (costs recoverable from production) upon Nuclear Fuels establishing a minimum 15 million pound uranium 43-101 compliant resource.

Wyoming is a proven and prolific uranium producer with a pro-energy government and established regulatory regime for the permitting and extraction of uranium through ISR technology. Wyoming is one of the few "Agreement States" hosting ISR uranium deposits, where the federal government and the Nuclear Regulatory Commission have ceded regulatory authority to the state government, making permitting and advancing uranium projects more efficient and streamlined as compared to most other states. Wyoming, with over 250 million pounds of historic uranium production, ranks as the state with the second most uranium production to date, most of which has been through the ISR technology since 1990, predominantly from the PRB.

The NI 3-101 Technical Report will be made available on SEDAR and the Company's website within the time prescribed by NI 43-101.
