WESTERN URANIUM & VANADIUM REPORTS A GREATER THAN 40% GRADE INCREASE IN THE FINAL ASSAYS OF URANIUM DELIVERIES

Western Uranium & Vanadium Corp. has concluded its recent uranium ore delivery program from the Sunday mine complex to Energy Fuels' White Mesa mill in Blanding, Utah. For further details regarding the uranium ore delivery program and related ore purchase agreement, please refer to the news release issued on April 14, 2025. The company is particularly encouraged by the final chemical assay results, which exceeded initial probe-indicated estimates. Western's Sunday mine complex stands as one of the few actively operating uranium and vanadium complex mines in the United States.

Postprocessing assays conducted by Western's customer under the ore purchase agreement showed natural uranium grades were more than 40 per cent higher than the initial probe estimates at delivery, resulting in a significantly larger final payment to Western. If these higher assay results are representative of the entire or a portion of the unmined and unexplored areas of the Sunday mine complex, it may indicate that the mineral resource exceeds significantly the original estimates derived from prior drilling data reported in the technical report on the Sunday mine complex dated July 7, 2015. The company is not treating the disclosure in this news release as technical disclosure concerning a mineral project, and investors should not rely on such disclosure until the company verifies and supports the disclosure in an updated or revised technical report or as otherwise required under National Instrument 43-101.

"We are extremely pleased with the results of the uranium ore delivery program," stated George E. Glasier, president and chief executive officer of Western. "The material increase between our probe-indicated grades and the final chemical assay results is a strong testament to the quality of Western's mineral resources at the Sunday mine complex."

The company remains committed to maximizing the economic recovery of its high-grade assets through efficient mining practices and strategic processing partnerships. These results provide further confidence in the company's ability to deliver consistent, high-value production as it advances its long-term development pipeline and works toward permitting the Mustang mineral processing plant site.
