May 30, 2024 Clean Air Metals Announces Planned CEO Transition and Files Audited Annual Financial Statements Thunder Bay, ON, May 30, 2024 – Clean Air Metals Inc. (“Clean Air Metals,” “Clean Air” or the “Company”) (TSXV: AIR; OTCQB: CLRMF; FRA: CKU) is pleased to announce the appointment of Mike Garbutt as its new President and Chief Executive Officer (CEO) effective July 1, 2024. Mr. Garbutt, a seasoned mining professional with a record of success, has significantly contributed to the Company’s strategic vision and development as COO over the past few years. Mike has the ideal skillset to lead the Company through potential asset acquisitions, resource expansion plans, and, ultimately, a mine development project. "Succession planning has been at the forefront of our minds since Mike joined Clean Air Metals 2 years ago,” said Jim Gallagher, outgoing CEO and returning Board Chair. "Mike's leadership and involvement, particularly in the due diligence review of other PGE assets in Northwestern Ontario, have been invaluable. He has demonstrated that he is uniquely qualified to carry forward our strategic initiatives.” Mr. Garbutt's tenure as President and CEO comes at a crucial juncture for Clean Air Metals, as the Company demonstrates its resilience in the face of industry headwinds. Despite these challenges, Clean Air Metals has maintained a strong cash position, honed its project targeting, and strategically planned for resource base expansion through the potential acquisitions of other PGE assets. "Being appointed CEO of Clean Air Metals is a tremendous honour," said Mike Garbutt. "I am excited to lead this exceptional team as we execute our strategy, capitalize on the opportunities ahead and create value for our shareholders. With Jim's continued support on the Board, alongside our recent additions of Dr. Lionnel Djon as VP of Exploration and Dr. David Peck to the Board of Directors, I am confident that we have one of the strongest teams in the junior sector." Clean Air Metals remains steadfast in its strategic focus on PGEs with associated copper exploration in Northern Ontario, leveraging the region's unique potential and scarcity of active exploration efforts. With an ongoing commitment to technical innovation and exploration excellence, the Company is well-positioned to seize the opportunities presented by the impending commodities super cycle, further enhancing its competitive edge. "I am pleased to be able to hand the reins to Mike after a challenging year during which we redefined the Company's strategy and strengthened the team," said Jim Gallagher. "I started my mining career as a labourer at INCO's Levack mine 47 years ago. It is time for me to step back from Clean Air’s day-to-day activities, but I’ll remain on the Board of Directors supporting Mike and the rest of the team as they execute the strategy moving forward. In my long career, I have lived through several metal price super cycles and truly believe that with the low investment environment over the last few years combined with the Green Energy revolution and the desperate need for Critical Metals, we are on the cusp of one of the greatest metal cycles of recent times. I believe Clean Air Metals is well poised to take full advantage of the upcoming super cycle.” Jim Gallagher will assume the role of Non-executive Chair of the Board of Directors starting July 1, 2024. He replaces Dean Chambers, who will continue his board roles as Chair of the Audit and Governance, Nominating and Compensation committees. We thank Dean for serving as Chair of the Board over the last year. About Jim Gallagher, PEng.
