REalloys, a rare-earth and advanced materials company currently in the process of merging with Blackboxstocks (NASDAQ: BLBX), today announced that Stephen S. duMont, president of GM Defense, has been named non-executive chairman of the board of directors.

The addition of duMont, a recognized leader in defense and aerospace innovation, brings extensive experience and strategic vision to REalloys as the company accelerates efforts to construct a fully integrated, North American mine-to-magnet supply network amid escalating global competition in critical minerals.

This leadership announcement follows REalloys’ recently executed 10-year, 6.75-million-ton supply agreement with Critical Metals Corp. (NASDAQ: CRML) and a complementary strategic sourcing partnership with St George Mining Limited (ASX: SGQ). These initiatives align with REalloys’ strategy to reduce Western dependence on Chinese processing capacity and strengthen allied industrial autonomy.

A Leader at the Crossroads of Defense and Industry

duMont currently oversees General Motors’ global defense and government division, which develops advanced tactical mobility, electrification, and autonomous systems for defense customers. Under his leadership, GM Defense has delivered several flagship programs, including the U.S. Army’s Infantry Squad Vehicle (ISV), the Canadian Light Tactical Vehicle (LTV), and the Suburban Shield – Heavy Duty Armored SUV for the U.S. State Department’s Diplomatic Security Service.

“REalloys stands at the heart of an effort critical to freedom, prosperity, and autonomy across the Western world,” said duMont, non-executive chairman of REalloys. “I have great respect for REalloys’ critical mission and the team’s work to strengthen North-America’s industrial resilience through innovation and partnership. Working with our partners across the North American defense industrial base, REalloys is driving a coordinated effort under Title 50 authorities, to ensure allied defense modernization, and broader U.S.–Canadian defense alignment to reinforce the supply chains that underpin both national and economic security. As I continue to focus on my important mission with General Motors, I’m proud to now also help advance this vital effort at such a pivotal moment for our nation and our trusted allies.”

Before joining General Motors, duMont held senior executive roles with Raytheon Technologies, BAE Systems, and Boeing, and chaired Thales-Raytheon Systems, one of the longest-running U.S.–European defense joint ventures. A decorated U.S. Army veteran, he served as an AH-64 Apache attack helicopter pilot before transitioning to industry.

He earned a Bachelor of Science degree in biology from Norwich University’s Military College, completed graduate work at Harvard Medical School, holds an MBA from Embry-Riddle Aeronautical University and a post-MBA from Villanova University, and pursued executive leadership studies at Stanford University.

A Board Built for Allied Strategy

duMont joins an accomplished board that includes Ambassador David MacNaughton, former Canadian ambassador to the United States and founding president of Palantir Canada, and Brad Wall, former premier of Saskatchewan and now special adviser on policy, trade and industrial competitiveness at Osler, Hoskin & Harcourt LLP.

Together, the board’s expertise spans diplomacy, trade, and defense industrial cooperation. Their collective experience supports the frameworks of Title 50 and 10 U.S.C. § 4872, which guide U.S.–Canadian collaboration in national security and critical materials sourcing. This alignment reinforces a unified North American approach to developing allied rare-earth capacity as the U.S. and Canada modernize NORAD, expand interoperability, and advance cross-border defense-industrial integration through initiatives such as the ICE Pact.

Advancing a Western-Controlled Supply Chain

REalloys is progressing plans to create a “no-China nexus” rare-earth network by sourcing raw materials exclusively from allied partners and performing processing, separation, refining, metallization, and magnet manufacturing entirely within North America. The vertically integrated model is designed to provide a reliable, compliant supply of rare-earth materials essential for defense, electric vehicles, and renewable energy industries.

“Stephen’s appointment as chairman is a defining moment for REalloys,” said Lipi Sternheim, founder and chief executive officer of REalloys. “His depth of experience with global defense systems and government relations will strengthen our ability to advance North America’s security and industrial resilience. As global supply chains and strategic alliances are being reshaped, Stephen’s strategic guidance will help position REalloys as a bridge between national defense priorities and the manufacturing capacity that underpins them. His background in the defense industrial base gives him a unique perspective on how secure, allied supply chains can safeguard the national security interests of the United States, Canada, and our global allies.”

Leadership Transition

REalloys also announced that David Argyle has resigned as chief executive officer and director of the Company. Following his departure, Leonard (Lipi) Sternheim, the Company’s founder and former executive chairman, has assumed the role of chief executive officer.

Mr. Sternheim will lead REalloys through its next phase of growth, focusing on scaling its vertically integrated North American rare-earth production platform and advancing its mission to secure the materials vital to Western defense, energy, and technological leadership.
