Nexus Executes Agreement to Acquire 100% Interest in Chord Uranium Project

Vancouver, British Columbia–(Newsfile Corp. – December 2, 2025) – Nexus Uranium Corp. (CSE: NEXU) (OTCQB: GIDMF) (FSE: JA7) (“Nexus” or the “Company“) is pleased to announce it has executed a mineral property purchase agreement (the “Agreement“) to immediately acquire a 100% interest in the Chord uranium project (the “Chord Property“), located in Fall River County, South Dakota. The Agreement replaces a previous option agreement and will provide Nexus with full ownership of the Chord Property, including State Section 36, currently being permitted. In total, the Chord Property now consists of 3,640 wholly owned acres.

Strategic Rationale

The Chord Property consolidates Nexus’s land position in Fall River County, which lies within the southern Black Hills uranium district. The district has a history of uranium production and hosts geology favorable for sandstone-hosted uranium mineralization. The Chord Property alone contains total inferred mineral resources of 2.75 Mlb U₃O₈ at an average grade of 810 ppm over an average thickness of 8.5 feet (Chord Uranium Project NI 43-101, updated September 2025, prepared by BRS Inc.), with significant exploration upside potential. The Company aims to demonstrate the extension of mineralization south of the known October-Jinx mineralization onto the State Section 36 and evaluate the potential for in-situ recovery (ISR) with an upcoming exploration and drilling program anticipated to commence in early 2026 pending permitting.

“This acquisition represents an important step in consolidating our South Dakota uranium portfolio,” said Jeremy Poirier, CEO of Nexus Uranium. “With uranium recently designated as a critical mineral by the U.S. Government, we believe domestic uranium projects in established mining jurisdictions will play an increasingly important role in meeting America’s energy security needs.”

The Chord Property acquisition follows the Company’s September 2025 completion of its arrangement with Basin Uranium Corp., through which Nexus acquired Basin’s existing uranium project portfolio.

Transaction Highlights

Under the terms of the Agreement, Nexus agreed to acquire a 100% interest in the Chord Property by paying aggregate consideration of US$100,000 cash and issuing 250,000 common shares to the vendors upon closing. The vendors will retain a 1.0% net smelter returns royalty (NSR) on future production, of which Nexus holds the right to repurchase 50% (being 0.5% NSR) for US$1,000,000 at any time prior to commencement of commercial production.

The transaction is subject to acceptance by the Canadian Securities Exchange (the “Exchange“). Closing is expected to occur within two business days following Exchange acceptance. Any shares issued pursuant to the Agreement will be subject to a statutory hold period of four months.
