Vancouver, British Columbia--(Newsfile Corp. - January 15, 2026) - Nexus Uranium Corp. (CSE: NEXU) (OTCQB: NEXUF) (FSE: JA7) ("Nexus" or the "Company") announces the acquisition of the Deadhorse uranium project in South Dakota. The project was acquired via staking and is wholly owned with no underlying royalties.

The Deadhorse project comprises 17 unpatented lode mining claims totalling approximately 340 acres, located within three miles of the Company's flagship Chord uranium project in Fall River County, South Dakota. The strategic acquisition consolidates Nexus's land position in a historic uranium district and advances the Company's goal of building a standalone ISR project in South Dakota, along with its portfolio of US assets.

"The Deadhorse acquisition reinforces our thesis that the lands surrounding the Chord project host significant uranium exploration potential," said Jeremy Poirier, CEO. "With nuclear energy firmly established as a critical component of the clean energy transition, the United States faces a structural supply deficit-importing over 90% of its uranium requirements. By systematically expanding our footprint in South Dakota, we are positioning Chord to be a standalone uranium project to contribute to domestic supply security while creating value for our shareholders."

Project Details

The Deadhorse 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 pounds¹ of U₃O₈. 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.
