Completion Of Duck Creek Drill Program

VANCOUVER – Noble Plains Uranium Corp. reported on its completed 148-hole, 30,825-foot drill program at its flagship Duck Creek Project in Wyoming’s Powder River Basin.
“This drill program has exceeded our expectations across the board,” said Drew Zimmerman, CEO. “We confirmed historic data, expanded the mineralized footprint, delivered multiple program-high grades, and achieved a 90% hit rate across 148 holes, all in under six months of acquisition. Duck Creek has gone from an overlooked historical asset to a project with the scale, continuity and grade profile to support a meaningful resource this spring. This program is how we build out real uranium pounds in premier U.S. jurisdictions at a time when domestic supply of this critical mineral has never been more urgent.”
This final batch delivered some of the strongest results of the entire program and caps a drill campaign that has consistently exceeded expectations. Hole 25-16-140 returned 17.5 feet of 0.235% eU₃O₈, including 2.0 feet grading 1.00% eU₃O₈ and 1.0 foot at 1.49% eU₃O₈. Hole 25-28-143 intersected 9.0 feet of 0.228% eU₃O₈, including 5.5 feet at 0.362% eU₃O₈ and 1.0 foot at 0.972% eU₃O₈. Importantly these high-grade intercepts continue to occur within the same laterally continuous roll-front system that has now been traced across the property. Rather than isolated high-grade hits, these results sit within a broader, predictable mineralized corridor that is ideally suited to ISR extraction.
Beyond the individual highlights, the significance of this program lies in the consistency and reproducibility of the results. A total of 148 holes were completed, every planned confirmation hole successfully twinned historic drilling, and 90.12% of all holes intersected uranium mineralization at or above the 0.02% eU₃O₈ cut-off grade. As drilling progressed northward, strong intercepts continued to be encountered, directly supporting the Company’s recent 2.25-mile expansion of the project footprint along trend.
In the past six months, Noble Plains progressed Duck Creek from the closing of the acquisition, through permitting, to the completion of a highly successful drill program that now provides a robust dataset to support a resource estimate in compliance with NI 43-101 standards this spring. This is the Company’s strategy in action: not grassroots exploration, but the disciplined conversion of known historical mineralization into newly defined, compliant uranium pounds in the ground.
All of the holes drilled are vertical and the geological units are essentially flat so that intercept widths are interpreted to be true thickness. The water table in all hole’s ranges from a depth of 5 feet to 75 feet and averages 16.5 feet deep.
“The strength and continuity of the results of this program are extremely important because they occur along the same historic trend that originally drew us to Duck Creek, and they are confirming that the roll-front system is both continuous and capable of hosting higher-grade centres within that continuity,” said Paul Cowley, P.Geo., COO. “Across 148 holes we have consistently reproduced and expanded upon the historic data, with grades and thicknesses that validate our geological model. The strength and predictability we are seeing along this trend gives us a high level of confidence that the system is likely to continue onto our newly staked northern ground. This is exactly the type of geological consistency you want to see when advancing a project toward a scalable ISR uranium resource.”
