North Shore Receives Exploration Permits for Rio Puerco Uranium Project, Engages Marketing

VANCOUVER, BC / ACCESS Newswire / May 26, 2026 / North Shore Uranium Ltd. ( TSXV:NSU )( OTCQB:NSURF ) (" North Shore " or the " Company ") is pleased to report that it has received the permits required to commence its first drill program at its Rio Puerco uranium project in the Grants Uranium District of northwestern New Mexico (" Rio Puerco " or the " Project "). The Company has received approval of its Minimal Impact Exploration Operation Permit from the state of New Mexico and its Notice of Intent to conduct mineral exploration activities at Rio Puerco from the Bureau of Land Management. North Shore's drill contractor Harris Exploration Drilling and Associates has mobilized to the Project and the Company expects to commence its initial Rio Puerco drill program in the near term.

North Shore plans to drill up to 26 holes and the main objective of the program is to begin validating and further evaluating historical exploration data generated by the Kerr-McGee Mining Corporation in the 1960s and 1970s. Details of the 2026 drill program were reported on April 9, 2026 . Brooke Clements, President and CEO of North Shore stated: " We look forward to getting the drill turning at Rio Puerco soon.

The Rio Puerco Project represents an exciting growth opportunity for North Shore and we look forward to validating the historical work completed by Kerr-McGee and confirming the significant exploration potential of the Project. World energy demand is increasing and the United States has indicated an intention to increase its domestic uranium supply, and we believe this supports advancing a project like Rio Puerco."
