Noble Plains Uranium Completes Shirley Central Historical Drill Database, Unlocking 341 Uranium Intercepts

Vancouver, British Columbia--(Newsfile Corp. - July 9, 2026) - Noble Plains Uranium Corp. (TSXV: NOBL) (OTCQB: NBLXF) (FSE: INE0) (" Noble Plains " or the " Company ") a U.S.-focused uranium exploration and development company, is pleased to announce it has completed the digitization and geological interpretation of the historical drill database at its Shirley Central Project in Wyoming's prolific Shirley Basin. Using AI-powered computer vision to process 1,211 historical drillholes acquired from Ur-Energy Inc., the Company has converted decades-old files and scanned gamma logs into a modern, high-resolution geological model, identifying 341 qualifying uranium intercepts and informing the placement of seven confirmation drill holes designed to fast-track Shirley Central toward a potential mineral resource. "This is our strategy in action, once again," said Drew Zimmerman, CEO of Noble Plains Uranium. "At Duck Creek, we proved that historical drilling can be converted into a compliant, scalable resource faster and more economically than starting from scratch. At Shirley Central we are aiming to do it again with over 1,200 historical drillholes, data that would have cost in excess of US$6 million to generate through new drilling alone. With 341 qualifying intercepts in clear roll front clusters, we have been able map out confirmation drill holes. This is disciplined, data-driven exploration and it is exactly the playbook we intend to keep running across our growing Wyoming portfolio." The Shirley Central Property consists of 30 strategically located mineral claims that are directly adjacent to Ur-Energy's producing Shirley mine. Noble Plains first identified a dense concentration of historic drill pads on the Shirley Central ground from historical aerial photographs, a strong indicator of the higher-grade mineralization that drew intensive historic drilling to the property in the first place. The Company acquired the underlying raw historical drill data directly from Ur-Energy; however, the dataset existed only as old, scanned gamma logs and was not usable in a modern resource-estimation workflow. Turning a Legacy Paper Archive Into a Modern Geological Model Noble Plains engaged Geomorphic AI's purpose-built artificial intelligence and computer vision systems to systematically extract, standardize, and analyze the full 1,211-hole dataset, accurately extracting gamma-ray traces across multiple historical log formats and converting CPS readings into estimated eU₃O₈ grades. The result is an integrated visualization platform incorporating maps and 3D geological modelling, turning a historically unusable paper archive into a modern exploration dataset comparable to what the Company could otherwise only obtain through a multi-million-dollar drill program of its own. 341 Qualifying Intercepts Define High-Grade Drill Targets Of the 1,211 historical holes reviewed, 341 intercepts qualified above a cut-off grade of 0.02% eU308 and a minimum thickness of 2 feet. These 341 intercepts average 0.055% eU308 over an average thickness of 13.7 feet. All intercepts were manually verified by Company geologists for accuracy, and multiple nose signatures that are indicative of roll-front uranium systems and associated with higher-grade centers were identified during the review. More than 57% of these selected intercepts returned grades above 0.05% eU308, underscoring the strength of the mineralization identified across the property. Standout results include a 4-foot intercept grading 0.58% eU308 from a depth of 185-189 feet in hole TX-2763, and a 6.3-foot intercept grading 0.53% eU308 from a depth of 448.6-454.9 feet in hole SX-683. Seven Confirmation Holes Target the Highest-Confidence Clusters Building on the results from Geomorphic AI and the Company's internal geological review, Noble Plains has selected seven drill locations for a confirmation program focused on two of the most prospective intercept clusters identified, both characterized by the nose features associated with higher-grade uranium accumulation. This targeted approach mirrors the strategy that delivered a 90% hit rate across the Company's 148-hole confirmation program at Duck Creek: rather than drilling broadly across the property, Noble Plains is placing holes precisely where the historical data indicates the highest probability of success, with the objective of validating the historical dataset and advancing Shirley Central toward a compliant mineral resource. Shirley Central: A Strategic Location for Future ISR Development Shirley Central consists of 30 unpatented mineral claims covering 665 acres adjacent to the boundary of Ur-Energy's Shirley Basin ISR Project, which currently hosts a NI 43-101 compliant Measured & Indicated resource of 8.816 million lb U₃O₈ at 0.23%¹ and has started full scale uranium production operations and transport of uranium-loaded resin to their Lost Creek processing facility².
