Vancouver, British Columbia--(Newsfile Corp. - November 25, 2025) - Nexus Uranium Corp. (CSE: NEXU) (OTCQB: GIDMF) (FRA: 3H1) ("Nexus" or the "Company") is pleased to announce it has become a member of the South Dakota Mineral Industries Association ("SDMIA"), the unified voice for the mineral industries in South Dakota.

The membership aligns with Nexus's expanding uranium exploration activities in South Dakota, where the Company controls two strategic uranium projects. These projects position Nexus as a significant stakeholder in South Dakota's uranium development sector.

"Joining SDMIA represents our commitment to responsible mineral development in South Dakota and our dedication to collaborative engagement with industry partners, local communities, and policymakers," said Jeremy Poirier, Chief Executive Officer of Nexus Uranium. "As we advance our South Dakota uranium projects, this membership provides an important platform for contributing to the state's mining heritage while ensuring best practices in environmental stewardship and community relations."

The membership comes at a pivotal time as the United States seeks to strengthen its domestic critical mineral supply chains, with uranium playing a crucial role in energy security and the nation's clean energy transition.
