OTCQX:NFUNF

VANCOUVER, Oct. 30, 2024 - Nuclear Fuels Inc. (CSE: NF) (OTCQX: NFUNF) ("Nuclear Fuels" or the "Company") announced today the best results to date from the on-going drill program at the Kaycee In-Situ Recovery ("ISR") Uranium Project (the "Project") in Wyoming's Powder River Basin ("PRB"). The current drill hole results are from the Company's first drilling on the historic Stirrup West and East Zones which lie ~2.7 miles from the Saddle Zone and 1 mile from the Spur Zone. Drilling at the Stirrup West Zone returned up to 0.205% eU₃O₈ over 8.0 feet with a Grade Thickness ("GT") of 1.640, representing the highest GT encountered by the Company. Drilling at Stirrup East Zone has confirmed high grade historic mineralization, and extended the Zone by ~1,000 feet to the northeast (0.107%eU₃O₈ over 4.5 feet with a total hole GT of 0.854). In the PRB, potentially ISR-recoverable uranium mineralization with a GT of greater than 0.20 is considered suitable for inclusion in a potential wellfield.

Significant Highlights of the Q3/24 Kaycee Project Drilling Program include:

• Drill hole JD24-002 at Stirrup West intersected 5 separate mineralized intercepts with a single 8.0 foot interval returning 0.205% eU₃O₈ for a Grade Thickness ("GT") of 1.640 and a total hole GT of 1.821;
  
  
• Drill hole JD24_058 was drilled as a step out hole to the north of the historical mineralization at the Stirrup West Zone and returned 0.077% eU₃O₈ over 5.0 feet, with a GT of 0.385. This hole, along with additional step out holes drilled to the south of the historical mineralization, suggests the potential to significantly extend the Stirrup West Zone to the north as well as towards the Spur Zone to the south;
  
  
• Hole JD24_063 at Stirrup East Zone returned 0.107% eU₃O₈over 4.5 feet, with a GT of 0.482, as well as an additional interval of 0.057% eU₃O₈ over 6.5 feet, for a total hole GT of 0.854 extending mineralization 1,000 feet to the northeast from the historic resource area;
  
  
• A total of 107 holes were drilled with an average depth of 498.9 feet, with 83% (90) of these drill holes returning anomalous uranium; 18 of the drill holes returning GT of 0.2 or better.

Greg Huffman, Chief Executive Officer, stated: "We continue to be impressed with not only our confirmation of existing historical areas of uranium mineralization, but by how quickly we have been able to extend several of the Zones at Kaycee along trend. We are now of the belief that a number of these discrete historical areas are likely to connect and combine into larger mineralized areas."

Table of Significant Results from the Kaycee Uranium Project Drill Program

Drill holes are reported that returned significant zones of uranium mineralization with >2 ft thickness at or above a grade cut-off of 0.02 per cent eU₃O₈ or that are relevant to exploration targeting. (1) % eU₃O₈ by Gamma logging is a measure of gamma intensity from a decay product of uranium. Gamma log assays may be in disequilibrium with ICP-MS assays. Comparisons of eU₃O₈ Gamma log and ICP-MS assays of Powder River Basin core samples indicate that eU₃O₈Gamma is comparable to ICP-MS uranium assay in the Powder River Basin. (2) Grade Thickness, or GT, is defined as the product of the mineral grade multiplied by the thickness of the mineralization.

Stirrup Zone Drill Program

The Stirrup West and Stirrup East Zones are located approximately 0.8 miles north and 1.2 miles northeast of the Spur Zone, respectively. In Q3/24, 74 drill holes were completed at the Stirrup Zones to an average depth of 491.0 feet and were designed to confirm mineralization encountered during previous exploration work in the 1970s and early 1980s, as well as to test for possible extensions of the mineralized zones. Of the 74 holes completed at the Stirrup Zone, 50% (37 drill holes) returned anomalous gamma values; 16 holes returned a GT of 0.20 or better, including 6 holes with a GT greater than 0.5.

The exploration program at the Kaycee Uranium Project continues to drill step outs from known historic resources along trend as we extend the known mineralization, while we are also testing regional targets that have not been previously explored for uranium mineralization. These targets have been generated by the evaluation of over 500 newly acquired oil and gas logs, and would represent potential new uranium discoveries on the Project.

Kaycee Uranium Project, Wyoming

The Kaycee Project in Wyoming's PRB, Nuclear Fuels' priority project, consists of 55 square miles of mineral rights over a 35-mile mineralized trend hosting 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 eU₃O₈ 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, permitting and advancing uranium projects is 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 PBR.

Drill holes were completed by Single Water Services using a rotary drill rig. Chip samples are collected for lithological logging every five feet. Century Geophysics of Tulsa Oklahoma is contracted to conduct downhole gamma ray, resistivity, spontaneous potential, and deviation. Century Geophysics calibrates the downhole tools in the US Department of Energy uranium logging Test pits in Casper Wyoming, to ensure the accuracy of the down hole gamma ray log measurements. % eU₃O₈ is a measure of gamma intensity from a decay product of uranium and is not a direct measurement of uranium. Numerous comparisons of eU₃O₈ and chemical assays of PBR core samples indicate that eU₃O₈ is a reasonable indicator of the actual uranium assay.
