Noble Plains Uranium Extends Consistent Mineralization at Duck Creek Project in

Wyoming

January 6, 2026 – Vancouver, British Columbia – Noble Plains Uranium Corp. (TSX-V: NOBL, OTCQB: NBLXF,

FSE: INE0) (“ Noble Plains ” or the “ Company”) a U.S. focused uranium exploration and development

company, is pleased to announce 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 0.06 3% 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 data set with the intent of facilitating a more r obust

compliant resource estimate when we progress to that step this spring.”

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. These ranges were based on assumed Grade -Thickness

(“GT”) values of 0.2 for the lower case and 0.598 for the upper case. 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.

the 3-mile-long trend of historic drilling.

Ongoing Drill Program Overview

The Duck Creek drill program, permitted for up to 37,400 ft across ~150 holes, is structured around three

key objectives:

1. 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.

2. Expansion of Shallow Mineralisation ~ 130 Holes

Designed to extend mineralised boundaries and target higher -grade areas along the 3 -mile-long

Wasatch roll-front corridor.

3. 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.

Details of the Drilling Program

* The geophysical results are based on equivalent uranium (eU3O8) of the gamma -ray probes calibrated at the

Department of Energy’s Test Facility in Casper, Wyoming. A geophysical tool with gamma-ray, spontaneous potential,

resistivity, and drift detectors was utilized. The reader is cautioned that the reported uranium grades may not reflect

actual concentrations due to the potential for disequilibrium between uranium and its gamma emitting daughter

products. The drill results were determined using thickness and grade % cutoffs of 2-ft, 0.02% eU3O8 and GT >0.2.

The holes drilled to date are generally 120-160 feet apart and have now covered a strike length of roughly

1.5 kilometres (0.93 miles) . 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.

Next Steps and Outlook

Drilling remains ongoing, and Noble Plains will continue to report results in batches as the program

progresses. With confidence building across the system and a substantial portion of the program still

ahead, the Company believes Duck Creek offers meaningful upside as it advances toward its first compliant

uranium resource.
