2025-10-21 15:00:54 ET
The appointment strengthens REalloys' strategic leadership as it builds a fully North American mine-to-magnet ecosystem amid intensifying global competition with China.
REalloys Inc., the rare-earth and advanced materials company set to merge with Blackboxstocks Inc. (NASDAQ: BLBX ), has appointed Stephen S. duMont , President of GM Defense, as Non-Executive Chairman of its Board of Directors. The move adds a high-profile defense-industry executive to REalloys' leadership as the company accelerates plans to establish a secure, Western-aligned supply chain for critical materials.
The appointment follows REalloys' recently announced 10-year, 6.75-million-ton offtake agreement with Critical Metals Corp. (NASDAQ: CRML ) and a strategic supply commitment with St George Mining (ASX: SGQ ), part of a broader effort to reduce dependence on Chinese processing capacity and strengthen North America's industrial resilience.
Defense Leadership for a Strategic Mission
With more than three decades of experience spanning defense, aerospace, and national security, duMont currently leads General Motors' global defense and government business, developing advanced mobility, autonomous systems, and battery-electric tactical power solutions for military and government customers. Under his leadership, GM Defense has delivered key programs including the U.S. Army Infantry Squad Vehicle, the Canadian Light Tactical Vehicle, and the Suburban Shield Armored SUV for the U.S. State Department.
"REalloys stands at the heart of an effort critical to freedom, prosperity, and autonomy across the Western world," said duMont. "Working with our partners across the North American defense industrial base, REalloys is helping ensure allied modernization and the secure supply of materials that underpin both national and economic security. I'm honored to help advance this vital mission alongside my ongoing work at General Motors."
Before joining GM, duMont held senior roles at Raytheon Technologies, BAE Systems, and Boeing, and served as an AH-64 Apache pilot in the U.S. Army. He holds degrees from Norwich University, Harvard Medical School, Embry-Riddle, Villanova, and Stanford.
A Board Shaped Around Allied Security
duMont joins a board that already includes Ambassador David MacNaughton, former Canadian Ambassador to the U.S. and founding president of Palantir Canada, and Brad Wall, former Premier of Saskatchewan and now Special Advisor on policy and industrial competitiveness at Osler, Hoskin & Harcourt. Together, they bring deep experience in diplomacy, energy security, and defense industrial cooperation--an alignment that reflects the Title 50 and 10 U.S.C. 4872 frameworks guiding U.S.-Canadian defense coordination and sourcing rules for critical materials.
Building a Western Mine-to-Magnet Chain
REalloys is developing what it calls a "no-China nexus" rare-earth supply chain--sourcing feedstock from allied mining partners and processing, separating, refining, and producing magnets entirely within North America. The company's vertically integrated model aims to support the modernization of NORAD, strengthen ICE Pact industrial cooperation, and ensure that defense-grade materials are produced under Western oversight.
"Stephen's appointment is a defining moment for REalloys," said Lipi Sternheim, Founder and newly appointed Chief Executive Officer of REalloys. "His experience in global defense systems and government relations will guide our mission to reinforce North America's security and industrial independence. As global supply chains realign, his strategic insight will help bridge defense priorities with the manufacturing base that supports them."
Leadership Transition and Next Steps
REalloys also announced that David Argyle has stepped down as Chief Executive Officer and Director. Sternheim, previously Executive Chairman, assumes the CEO role and will lead the company as it scales production and advances its North American rare-earth processing and magnet manufacturing capacity.
With its strengthened leadership, long-term supply agreements, and high-profile board, REalloys is positioning itself as a cornerstone of the Western critical-materials strategy--linking allied mining resources to end-use manufacturing for electric vehicles, defense platforms, and renewable-energy systems.
