QUANTUM JOINS THE CRITICAL MINERALS INSTITUTE (CMI)

Quantum Critical Metals Corp. has received approval to be a member of the Critical Minerals Institute (CMI).

As a member of CMI, Quantum gains access to a network of innovators and leaders across the critical mineral sector, creating new opportunities for collaboration to strengthen the strategic mineral supply chain in North America. The CMI is a global think tank and industry hub that equips governments, businesses and investors with resources and insights about the critical mineral industry.

Chief executive officer Marcy Kiesman stated:

"We are proud to be partnering with the Critical Minerals Institute as they support the clean energy transition, address supply chain vulnerabilities and strengthen national security. This partnership aligns with Quantum's strategic goal to contribute to a secure and sustainable critical metals supply chain for the West. We believe that membership in CMI will enhance Quantum's ability to build our strategic metal asset portfolio and play an active role in securing the supply chain. "

CMI executive director Tracy Hughes added:

"We are pleased to welcome Quantum Critical Metals Corp. and its CEO, Marcy Kiesman, into the membership of the Critical Minerals Institute at a time critical minerals are no longer a niche industrial concern -- they're the currency of geopolitical power, shaping supply chains from chips to clean energy. We look forward to Marcy's participation as a featured speaker at our upcoming CMI Summit V -- Command Capital in Critical Minerals: Aligning Government Priorities with Private Equity (May 13 to May 14, 2026, Toronto) -- where Quantum's focus on priority minerals such as gallium and cesium will help translate global supply chain imperatives into enduring industrial infrastructure."
