Noble Plains Uranium Delivers Highest-Grade Intercept to Date as Duck Creek Drilling Continues to Confirm Continuity
Noble Plains Uranium Delivers Highest-Grade Intercept to Date as
Duck Creek Drilling Continues to Confirm Continuity
January 22, 202 6 – 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 results from the next twenty drill holes completed at its flagship Duck
Creek Project in Wyoming’s Powder River Basin, highlighted by the highest -grade uranium intercept
recorded to date and continued strong mineralisation across the roll-front system.
The strongest result of the drill program to date was returned from hole 25-21-096, which intersected 35.5
feet of 0.202% eU₃O₈, including a high-grade core of 4.0 feet at 0.501% eU₃O₈, a standout intercept for a
Wyoming roll -front system. Additional strong results further demonstrate the consistency of
mineralisation encountered at Duck Creek, including 26.5 feet of 0.083% eU₃O₈ with 4.0 feet at 0.144%
eU₃O₈ in hole 25-21-095. Hole 25 -21-089 intersected 25.0 feet of 0.069% eU₃O₈ including 4.0 feet at
0.17% eU₃O₈, and hole 25 -21-090 intersected 17.5 feet of 0.09% eU₃O₈ including 2.0 feet at 0.217%
eU₃O₈.
Importantly, these results continue to align closely with the Company’s geological model, with this set of
holes hitting uranium mineralisation meeting or exceeding industry-standard thresholds for ISR-amenable
deposits in Wyoming with an 80% success rate. Together, these results reinforce both the quality of the
Duck Creek system and the growing confidence in its potential to support a meaningful uranium resource.
“The combination of consistent mineralisation and a standout 0.50% eU₃O₈ intercept underscores the
quality of the Duck Creek system,” said Drew Zimmerman, CEO of Noble Plains Uranium. “These results
reinforce our confidence that Duck Creek can support a me aningful, scalable uranium resource. We are
executing with discipline to convert drill results into future pounds in the ground, positioning Noble Plains
to deliver leverage in a U.S. uranium market where secure domestic supply is becoming increasingly
critical.”

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 the first 102 holes ranges from a depth of 5 feet to 75 feet and averages 16.5 feet deep.
“The highest-grade intercept of the program to date is important because it sits within a long, continuous
zone of uranium mineralisation, rather than being an isolated hit. This tells us the system is not only
extensive, but also capable of hosting higher -grade pockets within that broader trend, exactly what you
want to see in an ISR-amenable uranium deposit,” said Paul Cowley, P .Geo., COO of Noble Plains Uranium.
“To date we have now twinned 16 historic holes that have delivered reproducible results giving confidence
to historic drilling. With just over 2/3 of the planned program completed, the consistency of our results
continues to build confidence in our ability to define a meaningful, scalable uranium resource at Duck
Creek.”

the 3-mile-long trend of historic drilling.

Next Steps and Outlook
With roughly 2/3rds of the planned drilling now complete, Noble Plains believes Duck Creek continues to
de-risk rapidly as a future uranium resource. The consistency of mineralisation, increasing confidence in
grade continuity, and emergence of higher -grade zones collectively support the Company’s objective of
delivering its first NI 43 -101 compliant uranium resource later this spring. As drilling continues, the
Company expects additional results to further refine the scale and quality of mineralisation while
maintaining strong momentum toward resource definition.
Duck Creek remains central to Noble Plains’ strategy of building a growing inventory of U.S.-based uranium
pounds in known production areas that is positioned to benefit from a strengthening uranium price
environment and increasing focus on domestic critical-mineral supply.
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 Mineralization ~ 130 Holes
Designed to extend mineralized 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.
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.
Details of the Drilling Program
* The geophysical results are based on equivalent uranium ( eU308) 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% eU308 and GT >0.2.
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., sup ervised the drilling
activities.
