Quantum to highlight potential gallium and rubidium supply for defense and advanced technology applications

Vancouver, BC – TheNewswire - May 4, 2026 – Quantum Critical Metals Corp. (TSX.V: LEAP | OTCQB: ATOXF | FSE: 86A1) (“Quantum” or the “Company”) is pleased to announce that it will be exhibiting at the Hill Industry Partner Exchange (HIPE) 2026, taking place May 5–7, 2026, at the Ogden Eccles Conference Center in Ogden, Utah. The Company and its representatives will be located at Booth #20.

HIPE is a premier aerospace and defense supply chain event that convenes leaders from the U.S. Air Force, government, industry, and academia to address evolving supply chain challenges and opportunities. The 2026 theme, “Rapidly Changing Environments,” underscores the urgency of building resilient, secure, and adaptable supply networks.

Quantum’s participation highlights its commitment to supporting North American and allied supply chains through the development of strategic critical minerals, including its potential future supply of gallium and rubidium—materials increasingly recognized as vital to advanced defense and communications technologies.

Gallium is a key component in semiconductors, radar systems, and next-generation communications infrastructure, while rubidium has emerging applications in specialized electronics, defense technologies, and advanced energy systems. Both elements are considered supply-constrained and strategically important in the context of global geopolitical shifts and export controls.

Marcy Kiesman, CEO of Quantum commented, “As global supply chains continue to face disruption, the importance of secure, domestic sources of critical minerals like gallium and rubidium has never been more evident. HIPE provides an important forum for us to engage with defense stakeholders and demonstrate how Quantum can contribute to strengthening supply chain resilience for mission-critical technologies.”

At Booth #20, Quantum will present its critical minerals portfolio and outline its strategy to advance projects with the potential to supply materials essential to defense, aerospace, and high-performance electronics industries. The Company looks forward to connecting with procurement leaders, supply chain specialists, and strategic partners throughout the event. The Company is committed to supplying responsibly sourced materials essential to the global transition toward advanced technologies, energy security, and defense readiness.
