Vancouver, British Columbia — January 15, 2026 — Leads & Copy — Noble Plains Uranium Corp. (TSXV: NOBL) (OTCQB: NBLXF) (FSE: INE0) announced drill results from the next twenty drill holes completed at its Duck Creek Project in Wyoming’s Powder River Basin.
According to the company, the results demonstrate consistent uranium mineralization across the Duck Creek roll-front system. The company reports a high success rate of 85% of the holes meeting or exceeding industry-standard thresholds for Wyoming ISR deposits. These results reinforce the growing confidence in the Company’s geological model, validate the expanded project footprint, and further de-risk Duck Creek as it advances toward a scalable uranium resource.
Hole 25-21-069 intersected 26 feet of 0.117% eU308 including 3.0 feet of 0.369% eU308. Hole 25-21-079 intersected 19.5 feet of 0.137% eU308, including 7 feet of 0.212% eU308. Hole 25-21-076 intersected 18 feet 0.112% eU308, including 6.0 feet of 0.263% eU308 and hole 25-21-068 intersected 18 feet of 0.116 eU308, including 6.5 feet of 0.25% eU308.
Drew Zimmerman, CEO of Noble Plains Uranium, said that the latest batch of results continues to deliver. He added that the success rate of 85% reinforces the predictability of the Duck Creek system and validates the geological model and decision to expand the project footprint. Zimmerman said that they are methodically building scale, reducing risk, and advancing Duck Creek toward a compliant uranium resource.
The Duck Creek drill program is permitted for up to 37,400 ft across ~150 holes and is structured around three key objectives:
- Confirmation of Historic Data – 16 Holes to verify 1,317 historic intercepts in the Wasatch Formation and support a uranium resource prepared in accordance with National Instrument 43-101 standards.
- Expansion of Shallow Mineralization ~ 130 Holes designed to extend mineralized boundaries and target higher-grade areas along the 3-mile-long Wasatch roll-front corridor.
- First-Ever Drilling of the Fort Union Formation ~ 10 Holes for the first time, Noble Plains will drill to ~1,200 ft to test the Fort Union, where neighbouring projects host the majority of their compliant resources.
The Company filed a Technical Report, available on SEDAR+ under the Company’s profile, on the Duck Creek Project on August 14, 2025, which outlined an exploration target ranging from 2.37 million tons at 0.03% U₃O₈ to 5.45 million tons at 0.05% U₃O₈. The exploration target is conceptual in nature, does not meet the standards to be classified as mineral resources or mineral reserves, and there is no certainty that the exploration target will be realized.
Paul Cowley, P.Geo., COO of Noble Plains Uranium, said that the results continue to confirm the strength and predictability of the Duck Creek roll-front system to date along a 2.25km (1.4 miles) strike length. He added that the average grade of this next set of results is 0.069% eU3O8, 38% higher grade than the upper range of the Exploration Target of 0.05% eU3O8 used in the August 14, 2025 Duck Creek Technical Report and that mineralization is occurring where the model predicts, across a wider area of the project’s uranium trend. He believes this level of consistency supports the definition of a scalable uranium resource and materially reduces geological uncertainty as they progress toward a compliant estimate.
The drilling is being done by Tyler Exploration Inc. utilizing a truck mounted mud-rotary rig and the geophysical logging by Hawkins CBM Logging, both of Wyoming. Bradley Parkes P.Geo, VP Exploration and Paul Cowley P.Geo, Chief Operating Officer for Noble Plains Uranium Corp., supervised the drilling activities.
Noble Plains Uranium Corp. is a U.S.-focused uranium exploration and development company advancing a portfolio of projects amenable to In Situ Recovery (ISR). The company’s strategy targets historically drilled and underexplored assets in proven jurisdictions, with the objective of rapidly delineating NI 43-101 compliant resources and building a scalable inventory of domestic uranium.
