Blackboxstocks Inc. (NASDAQ: BLBX) announced that REalloys Inc. – its merger target – has appointed Stephen S. duMont, President of GM Defense, a division of General Motors (NYSE: GM), as non-executive Chairman of the Board. The move follows REalloys’ 10-year, 6.75-million-ton offtake agreement with Critical Metals Corp. (NASDAQ: CRML) and marks a major step in building a Western-aligned mine-to-magnet supply chain independent of China.
The appointment of duMont, a seasoned defense and aerospace executive, comes as REalloys accelerates its efforts to create a secure North American rare-earth processing and magnet manufacturing network. DuMont will provide strategic guidance as REalloys aligns its operations with U.S.–Canadian defense and industrial security priorities under Title 50 authorities and forthcoming DFARS sourcing rules.
REalloys is positioning itself as a cornerstone of Western efforts to establish an independent critical-mineral supply chain amid intensifying global competition with China. Its agreements with Critical Metals and Australia’s St George Mining (ASX: SGQ) form part of a broader initiative to ensure that rare-earth materials essential for defense, energy transition, and advanced manufacturing remain within allied supply networks.
DuMont brings more than 30 years of experience spanning Raytheon, Boeing, BAE Systems, and the U.S. Army, where he served as an Apache helicopter pilot. At GM Defense, he leads the company’s military and government programs, including the U.S. Army’s Infantry Squad Vehicle and the Canadian Army’s Light Tactical Vehicle programs.
He joins an experienced board that includes former Canadian Ambassador to the U.S. David MacNaughton, founding president of Palantir Canada, and former Saskatchewan Premier Brad Wall, now a policy and trade advisor at Osler, Hoskin & Harcourt LLP. Their combined expertise reflects REalloys’ ambition to act as a bridge between industrial capacity and national defense priorities.
REalloys also announced that David Argyle has resigned as CEO and director, with company founder Leonard “Lipi” Sternheim returning as Chief Executive Officer. Sternheim will oversee the scaling of REalloys’ vertically integrated North American operations in refining, separation, and magnet production.
The appointment underscores a growing push across North America to localize critical-mineral production as part of broader defense-industrial integration efforts, including NORAD modernization and the ICE Pact initiatives. With no Chinese nexus in its supply chain, REalloys aims to anchor Western security and technological independence through allied industrial strength.
