Noble Plains Uranium Completes Transformational Duck Creek Drill Program as Project Advances Toward First Compliant Resource

Executive Summary

• Noble Plains announced final results from a 148‑hole, 30,825‑ft drill program at the Duck Creek Project, delivering high‑grade intercepts (up to 1.49% eU₃O₈) and a 90 % hit rate.
• The data support a forthcoming NI 43‑101 compliant uranium resource estimate expected this spring, expanding the known roll‑front system and confirming continuity into newly staked northern claims.
• Three deep holes confirmed the presence of thick Fort Union sand bodies, opening additional upside for future roll‑front targeting.

Key Details

• Program Scope: 148 vertical holes, total depth 30,825 ft; all planned confirmation holes successfully twinned historic drilling.
• Hit Rate: 90.12 % of holes intersected ≥0.02 % eU₃O₈.
• Key Intercepts:
• Hole 25‑16‑140 – 4.5 ft @ 0.235 % eU₃O₈, including 2.0 ft @ 1.00 % and 1.0 ft @ 1.49 %.
• Hole 25‑28‑143 – 9.0 ft @ 0.228 %, including 5.5 ft @ 0.362 % and 1.0 ft @ 0.972 %.
• Additional Highlights (selected from Table 1):
• Hole 25‑15‑126 – 40 ft @ 0.043 %; includes 18.5 ft @ 0.064 % and 2.0 ft @ 0.141 %.
• Hole 25‑15‑129 – 45 ft @ 0.043 %; includes 7.5 ft @ 0.134 % and 3.0 ft @ 0.207 %.
• Hole 25‑16‑132 – 18 ft @ 0.048 %; includes 10.5 ft @ 0.073 % and 22 ft @ 0.042 %.
• Geophysical Confirmation: Gamma‑ray, SP, resistivity, and drift logs calibrated at DOE Test Facility; grades reported as eU₃O₈ with a 2‑ft/0.02 % cut‑off.
• Drilling Contractor: Tyler Exploration Inc.; downhole logging by Hawkins CBM Logging. Supervised by Bradley Parkes (VP Exploration) and Paul Cowley (COO).
• Fort Union Formation Test: Three deep holes penetrated “S”, “Q”, “O4”, and “O3” sands, confirming thick clean host sand bodies; roll‑front location still to be defined.
• Future Work: Final database compilation, geological modelling, and resource estimate preparation for spring 2026. Partnership with University of Wyoming to develop geophysical methods for deeper roll‑front identification.
• Strategic Impact: Positions Noble Plains to deliver a scalable ISR‑compatible uranium resource in the Powder River Basin, aligning with rising U.S. domestic supply demand and government support.

Notable Quotes

“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.” – Drew Zimmerman, CEO
“The strength and continuity of the results… are extremely important because they occur along the same historic trend… giving us high confidence that the system will continue onto our newly staked northern ground.” – Paul Cowley, COO
