Critical Elements Announces the Appointment of Mr. Kenneth Williamson as Director of Exploration

MONTREAL, November 10, 2025 - Critical Elements Lithium Corp. (TSX-V:CRE)(US OTCQX:CRECF)(FSE:F12) ("Critical Elements" or the "Corporation") is pleased to announce the appointment of Mr. Kenneth Williamson to the position of Director of Exploration. This newly created role with Critical Elements follows his experience as Vice-President Exploration for Power Metallic Mines Inc. (formerly Power Nickel), where his efforts were material to the confirmation and expansion of the Nisk Copper-Nickel deposit and participated to the discovery and the growth of the polymetallic Lion zone.

Mr. Kenneth Williamson (M.Sc., P.Geo), is a professional geologist with over 20 years of experience in the mining industry. Kenneth graduated from the University of Laval with a Master's Degree in Structural Geology in 2002. He was a Ph.D. candidate from 2002 to 2006, with studies on the structural controls leading to the formation of the world-class Goldcorp High Grade Zone. His work led to his appointment as Special Project Geologist at the Goldcorp Red Lake Mine in 2004. Kenneth brings his robust industry experience born of a strong scientific approach combined with the practicality necessitated by the "daily rush to feed the mill with high grade material".

Throughout Ken's career, 3D modeling has been central to his work, materially advancing the knowledge of:

• The Red Lake Mine litho-structural model during his Ph.D.

• The unified Campbell-Red Lake deposit-scale and Red Lake district-scale 3D litho-structural models after the merger of Goldcorp and Placer Dome in 2006.

• The Matagami district scale 3D geology model while at Québec's Ministère des Ressources naturelles et des Forêts in 2011.

• While with Premier Gold Mines in 2013 to 2015, the structural framework used at the Greenstone Gold Mine, now in its first year of production by Equinox Gold Corp.

• The structural model and targeting strategies at Radisson Mining Resources Inc.'s O'Brien mine between 2017 to 2019.

• The confirmation and expansion of the Nisk Copper-Nickel deposit and the discovery of the polymetallic Lion zone between 2019 to 2024, while working as consultant and later as Vice-President Exploration for Power Metallic Mines Inc.

"I am excited to team up with Critical Elements on this project and participate in the generation of a robust 3D model and targeting strategy along the Corporation's extensive 100 kilometer-long Nemaska belt land position," noted Kenneth Williamson. "We will build a rigorous drill plan benefiting from the exciting preliminary exploration results recently published on the Nemaska Belt properties." See the news release dated November 4, 2025.

CEO Jean-Sébastien Lavallée added, "We are excited to have Ken join the Critical Elements team and apply his extensive skill and experience. The logistics and preparation for a winter drill program on the Rose West lithium discovery located within 10 km of our flagship Rose Lithium-Tantalum project are in progress with drilling expected to commence this winter, shortly after freeze-up. Drill targeting on the Nemaska Belt will flow from compilation of the summer exploration data and Ken's invaluable work."
