Internationally respected geochemist to lead the Company's technical strategy and newly established International Technical Advisory Council as Quantum advances innovative critical minerals processing technologies toward pilot-scale validation and commercialization.

Vancouver, British Columbia – TheNewswire - July 20, 2026 – Quantum Critical Metals Corp. (TSXV: LEAP) (OTCQB: ATOXF) (FSE: 96A1) ("Quantum" or the "Company") is pleased to announce the appointment of internationally recognized geochemist Dr. Rob Bowell, Ph.D., to its Board of Directors. Dr. Bowell has also entered into an agreement with the Company as its Lead Technical Advisor and will serve as Chair of Quantum's newly established International Technical Advisory Council ("ITAC").

The appointment strengthens Quantum's technical leadership at a pivotal stage in the Company's evolution as it advances innovative processing technologies for the recovery of gallium, rubidium and other critical minerals from unconventional and conventional feedstocks while progressing toward pilot-scale validation, commercial deployment and the establishment of secure North American supply chains.

ITAC has been established to provide independent scientific, technical, engineering and strategic guidance to Quantum's Board of Directors and management as the Company advances its critical minerals technology platform. Under Dr. Bowell's leadership, ITAC will help guide technical development, support research and development initiatives, review metallurgical and engineering programs, evaluate emerging opportunities and contribute to the Company's long-term commercialization strategy.

Dr. Bowell is widely recognized as one of the mining industry's leading applied geochemists, with more than three decades of international experience spanning mineral exploration, metallurgical process development, hydrometallurgy, environmental geochemistry, mine waste valorization, due diligence and strategic resource development. Throughout his career, he has advised mining companies, governments, financial institutions and international organizations on technically complex mining and processing projects across more than 100 countries. He is registered as a professional geologist in the Provenance of Newfoundland and Labrador as well as in Europe and Namibia.  He is also registered as a chartered chemist with the Royal Society of Chemistry and has attained the designation of Qualified for Minerals Reporting (QMR) by the Institute of Mining Materials and Minerals in recognition of being a Competent Person (CP) or Qualified Person (QP) to sign off Public Reports. He also serves currently as an adjunct professor at Queens University, Kingston, Ontario, Canada.

Dr. Bowell's appointment follows a series of important technical and corporate milestones for Quantum, including encouraging metallurgical test work, advancement of its pilot-scale development strategy, expanded collaboration with government, academic and industrial partners, and continued progress toward commercializing innovative critical minerals processing technologies.

As both a Director and Lead Technical Advisor, Dr. Bowell will provide strategic oversight across Quantum's technical programs while helping guide the Company's scientific direction as it advances innovative processing technologies for the recovery of gallium, rubidium and other critical minerals from mica-rich feedstocks. As Chair of ITAC, he will coordinate the activities of the Council while providing independent guidance on scientific development, metallurgical optimization, engineering initiatives, technical risk management and future commercialization opportunities.

Marcy Kiesman, CEO of Quantum Critical Metals, commented, "We are extremely pleased to welcome Dr. Rob Bowell to Quantum.
