Consistent Mineralization Extended At Duck Creek Project

VANCOUVER – Noble Plains Uranium Corp. reported the fourth set of drill results with a further twenty drill holes completed at its flagship Duck Creek Project in Wyoming’s Powder River Basin. These results continue to demonstrate strong mineralisation, building further confidence in the Company’s geological model and supporting its objective of advancing Duck Creek toward a compliant uranium resource in 2026.
“With each new set of drill results, our confidence in Duck Creek continues to compound,” said Drew Zimmerman, CEO of Noble Plains Uranium. “We are seeing the consistency and repeatability that matters most at this stage, results that support a scalable uranium system and a clear path toward a compliant resource. This steady progress is exactly how value is built in a strengthening uranium market: by converting drilling success into defined pounds in the ground. Duck Creek is doing that, and it continues to reinforce why this project is central to our growth strategy.”
Of special note, hole 25-28-047 intersected 17.5 feet of 0.072% eU308 including 6.0 feet of 0.142% eU308. Hole 25-21-53 intersected 22.5 feet of 0.063% eU308, including 4.0 feet of 0.201% eU308. Hole 25-21-058 intersected 22.0 feet 0.051% eU308, including 3.0 feet of 0.118% eU308 and hole 25-21-59 intersected 8.0 feet of 0.165 eU308, including 3.0 feet of 0.136% eU308.
Collectively, results from the first four sets of drilling continue to show consistent grades and thicknesses across the mineralised trend, reinforcing the predictability of the system and reducing geological risk as the program advances. As both long-term contracting and spot uranium prices increase from a tightening uranium market, projects that can demonstrate scale, continuity, and a clear path to resource definition are increasingly valued. Duck Creek is progressing along that path with each new set of results.
“We continue to intersect consistent mineralisation with strong grades and thicknesses beyond historic drill results,” states Chief Operating Officer Paul Cowley. “Nearing the midway mark of our drill program we have now covered a strike length of 1.5 kilometres (0.93 miles) and are maintaining a GT 17% better than the higher end of the Exploration Target range in the Duck Creek NI43-101 report; 0.70 vs. 0.598. Only 3 of the 62 holes to date have been historic hole sites for confirmation. The other fifty-nine holes have spatially expanded the area beyond historic dataset with the intent of facilitating a more robust compliant resource estimate when we progress to that step this spring.”
