NEXUS URANIUM CONTINUES SOUTH DAKOTA EXPANSION WITH RC URANIUM CLAIMS ACQUISITION

Nexus Uranium Corp. has acquired the RC uranium project in South Dakota, the company's second strategic staking in the Fall River county uranium district in as many weeks. The project was acquired by staking and is wholly owned with no underlying royalties.

The RC project comprises 40 unpatented lode mining claims totalling approximately 800 acres, located within one mile of the company's flagship Chord uranium project in Fall River county, South Dakota. Combined with the recently announced Deadhorse acquisition (17 claims, approximately 340 acres), Nexus has added 57 claims totalling approximately 1,140 acres to its South Dakota land position in January, 2026, alone, bringing the company's total South Dakota holdings to approximately 6,380 acres.

"Following last week's Deadhorse acquisition, the RC staking extends our consolidation of the lands immediately adjacent to Chord," said Jeremy Poirier, chief executive officer. "At 40 claims and 800 acres situated less than one mile from our flagship project, RC represents the most proximal acquisition to date and reinforces our confidence in the district's exploration upside. We will continue to evaluate additional opportunities to expand our footprint in this historic uranium-producing region."

Project details

The RC claims are located in the located in the historic Edgemont uranium district, part of the broader Black Hills region, which has documented historical uranium production from sandstone-hosted deposits in the Inyan Kara group of approximately 3.2 million pounds of U3O8 (triuranium octoxide). The claims cover prospective ground within the same geological setting as the adjacent Chord project, where uranium mineralization is associated with Cretaceous-age sandstones and paleochannel systems within the Inyan Kara group.

Referenced nearby resources, deposits, projects and mines provide geologic context for the RC and Chord uranium projects but are not necessarily indicative that they hosts similar potential, size or grades of mineralization. No mineral resources have been estimated at the RC uranium project and there is no assurance that further work will result in a mineral resource classification. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
