We are delighted to welcome Tracy to our Board of Directors and look forward to the contributions she will make as we continue to advance our portfolio of critical mineral projects." Quantum Critical Metals has attracted increasing attention for its portfolio of strategic mineral assets in Québec and British Columbia, including projects prospective for gallium, cesium, rubidium, antimony, germanium, silver, and other critical materials essential to advanced manufacturing, semiconductors, energy security, telecommunications, and defense technologies. The Company's recent work advancing gallium extraction from mica-bearing pegmatites has highlighted the potential for new North American sources of materials that are increasingly recognized as strategically important by governments and industry alike. "I am honored to join the Board of Directors of Quantum Critical Metals," said Tracy Hughes.

"The global race to secure critical mineral supply chains continues to accelerate, and Quantum has assembled an impressive portfolio of projects targeting several of the minerals most essential to modern technologies, energy security, advanced manufacturing, and national defense. I have been particularly impressed by Marcy Kiesman's leadership, the Company's technical innovation, and its commitment to advancing critical mineral opportunities that could play an important role in strengthening North American supply chains. I look forward to supporting the Board and management team as they continue to create long-term value for shareholders."

Throughout her career, she has championed independent analysis, market transparency, and strategic collaboration across capital markets and the industries that support the global resource economy. The Company and its Board of Directors would also like to thank Ms. Melanie Mackay for her dedicated service as a director.
