NexMetals Initiates CEO Succession Plan

Vancouver, British Columbia--(Newsfile Corp. - December 15, 2025) - NexMetals Mining Corp. (TSXV: NEXM) (NASDAQ: NEXM) ("NEXM" or the "Company") announces that, following a transitional period, effective January 31, 2026, Mr. Morgan Lekstrom will be stepping down as Chief Executive Officer and will continue to serve the Company on the board of directors (the "Board"). Mr. Sean Whiteford, who currently serves as President of the Company, will be appointed as the Company's Chief Executive Officer.

During his tenure, Mr. Lekstrom drove the successful completion of the Company's 2025 restructuring and has been instrumental in strengthening NEXM's foundation for advancing its projects in Botswana. He led the raising of over $145 million, which included the equity conversion of the $20.8 million term loan provided by EdgePoint Investment Group Inc. and directed a portion of the proceeds toward the prepayment of the US$25 million asset purchase agreement milestone payment which secured title to both the Selebi and Selkirk assets. Mr. Lekstrom also led the Company as it advanced the technical evaluations on its Selebi and Selkirk projects including the ongoing deep drilling program and key metallurgical breakthrough at Selebi, expansion drilling programs, and the continued progression of initial economic studies for both properties expected to be completed in 2026.

Incoming CEO Mr. Whiteford brings over 30 years of experience in exploration, operational and business development roles across a wide range of commodities and geographies, including most recently as President of NEXM. As President, he has helped guide the Company's strategic direction and provided oversite on all aspects of the Botswana projects. Mr. Whiteford started his career with BHP and has held senior and executive positions with Rio Tinto and Cliffs Natural Resources.

On behalf of the Board, Paul Martin, Chairman of the Board, said "Mr. Lekstrom joined the Company at a particularly challenging point in its history and in a very short time has re-energized the potential and profile of our organization and our Botswana projects. We look forward to his continued contributions as a board member and thank him for overseeing and executing on the many achievements accomplished in 2025," Mr. Martin added, "Mr. Whiteford has been with the Company for over three years and has been working closely with Mr. Lekstrom over the past nine months. His extensive technical experience, and in-depth understanding of the assets, and the country that we operate in, makes him the ideal successor as we continue our drilling programs and move into the next phase of the projects' advancement, including the completion of our initial economic studies for Selebi and Selkirk."
