Noble Plains Uranium Commences Confirmation Drill Program at Shirley Central Project

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 mobilized a drill rig to its Shirley Central Project in Wyoming's prolific Shirley Basin for confirmation drill program designed to convert historical drilling data toward a compliant mineral resource estimate. Advancement from Historical Data to Drill-Ready Targets As previously announced, Noble Plains acquired a database comprising 1,211 historical gamma-ray logs from uranium exploration conducted between the 1950s and 1970s. These logs, historically stored as scanned images, contain extensive subsurface information but have not been usable in modern resource estimation workflows. Through its engagement with Geomorphic AI, Noble Plains converted this dataset into a digital format using a purpose-built computer vision pipeline calibrated specifically for legacy uranium logs 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. "Six million dollars of historical drilling data doesn't sit on a shelf at Noble, we turned it into drill targets," 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 doing it again with 341 qualifying intercepts in clear clusters, we have been able to map out confirmation drill holes. This is disciplined, data-driven exploration at its best, and it is exactly the playbook we intend to keep running across our growing Wyoming portfolio." Shirley Central Offers 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. The project is the news uranium mine in the United States and is now at full scale ISR operations, including transport of uranium loaded resign to Lost Creek for processing². The Project is also bordered by Uranium Energy Corp. (UEC), placing Noble Plains directly between two of the most active U.S. uranium developers. "The digitized dataset gives us an unusually clear picture of the mineralized system at Shirley Central before we ever turn a bit. The 341 qualifying intercepts define coherent roll-front trends, and this seven-hole program is designed to confirm those historical intercepts with modern, twinned data that meets current QA/QC standards," stated Paul Cowley, Chief Operating Officer of Noble Plains. "Success here means we can move directly toward an initial mineralization estimate and, ultimately, a NI 43-101 resource, looking to replicate the technical path we followed at Duck Creek on a project sitting immediately adjacent to a permitted, producing ISR operation."
