Jaguar Uranium Corp. (NYSE-AM: JAGU) ("Jaguar" or the "Company") announces the formal initiation of its initial exploration plan at the Huemul Project — a 27,700-hectare uranium-copper-vanadium district in Mendoza Province, Argentina, centered on Argentina's first-ever producing uranium mine. This comes against a backdrop of two recent landmark developments that directly validate Jaguar's position: the U.S.–Argentina Framework Instrument for Securing Critical Minerals Supply — signed February 4, 2026 at the Critical Minerals Ministerial in Washington, and Jaguar's own Collaboration Agreement with the Ministry of Energy and Environment of the Province of Mendoza, signed March 4, 2026 (the "Collaboration Agreement"), establishing formal government-to-company cooperation across the Company's Mendoza properties.
