UNXE238 Corp's Duck Creek Uranium Project Delivers Outstanding Drill Results: 42-Hole Program Validates Multi-Million Pound Exploration Target
December 30 , 2025
Exceptional Mineralization Confirmed Along 3-Mile Trend in Wyoming’s Powder River Basin UNXE238 Corp Retains 100% Ownership Until Option Commitments Fulfilled UNXE238 Corp. (“UNXE238” or the “Company”) is pleased to provide shareholders and stakeholders with an update on the exceptional drilling results being delivered at the Company’s Duck Creek Uranium Project in Wyoming’s prolific Powder River Basin. To date, 42 drill holes have been completed with consistently high success rates, confirming the strength and continuity of uranium mineralization at this strategically significant asset originated and assembled by UNXE238 Corp. As the originator and 100% owner of the Duck Creek Project—pending fulfillment of all option commitments by the option partner UNXE238 Corp is gratified to see its technical vision and project generation capabilities validated by these outstanding results.
Drilling Campaign Validates UNXE238's Technical Vision
The ongoing drill program at Duck Creek has demonstrated consistent and impressive results across 42 completed holes, with the majority of holes intersecting uranium mineralization well above industry-standard Grade-Thickness (GT) cut-offs,
Initial 8 Holes: Seven of eight holes intersected uranium mineralization with GT averaging 1.0 five times the industry standard cut-off of 0.2 typically used in Wyoming roll front uranium deposits.
Expanded to 24 Holes: Continued strong results with notable intercepts including 28.5 feet of 0.08% eU₃O₈ (including 6 feet of 0.18% eU₃O₈) and 29.0 feet of 0.043% eU₃O₈ (including 4.5 feet of 0.10% eU₃O₈).
Current 42 Holes: Standout intercepts include 13.5 feet of 0.063% eU₃O₈ (including 5.0 feet of 0.117% eU₃O₈) and a high-grade zone of 5.0 feet at 0.173% eU₃O₈ (including 3.0 feet of 0.257% eU₃O₈).
These results represent less than one-third of the planned 150 hole drill program permitted for up to 37,400 feet, with drilling ongoing and a compliant NI 43-101 resource estimate targeted for the first half of 2026.

UNXE238's Project Development Achievement
The Duck Creek Project exemplifies UNXE238 Corp’s strategic approach to uranium asset development, identifying high quality brownfield assets with extensive historical data in proven uranium districts, assembling comprehensive land positions, and creating value through methodical technical evaluation.
Key achievements by UNXE238 Corp at Duck Creek
Assembled four Wyoming State mineral leases covering 2,560 acres in the heart of the
Powder River Basin.
• Identified and compiled 4,068 historical drill holes from Kerr-McGee Nuclear
Corporation’s 1970s exploration program.
• Delineated a 3-mile-long uranium mineralization corridor within the Eocene aged Wasatch Formation with shallow mineralization (50-260 feet below surface).
• Commissioned an independent NI 43-101 Technical Report by WWC Engineering identifying an Exploration Target of 2.37 to 5.45 million tons at grades between 0.03% and 0.05% U₃O₈.
• Secured Surface Access Agreement with local rancher to facilitate exploration and
development activities
• Positioned the asset surrounded by operations of Cameco Corporation, Uranium Energy
Corp., and GTI Energy Limited
Strategic Value and ISR Development Potential
The Duck Creek Project is ideally situated in Wyoming’s Powder River Basin, which has produced over 238 million pounds of uranium since the 1950s. The property is amenable to In-Situ Recovery (ISR) mining the dominant and most environmentally responsible extraction method in Wyoming offering faster permitting timelines, minimal surface disturbance, and significantly lower capital and operating costs compared to conventional mining.
Historical drill intercepts identified by UNXE238 Corp include exceptional high-grade zones of 8.9 feet grading 0.75% U₃O₈ and 13.9 feet of 0.47% U₃O₈, demonstrating the project’s potential for significant uranium resources.
The deeper Fort Union Formation which hosts the majority of compliant resources at neighboring ISR projects has never been drilled at Duck Creek, presenting substantial exploration upside beyond the Wasatch mineralization currently being tested.
Ownership Structure
UNXE238 Corp retains 100% ownership of the Duck Creek Project until Noble Plains Uranium Corp. (TSX-V: NOBL), the option partner, fulfills all commitments under the property option agreement including cash payments totaling US$1,500,000 and issuance of 5,500,000 common shares over three years. UNXE238 Corp retains a 1% Net Smelter Royalty in perpetuity.
Management Commentary
“The outstanding drilling results at Duck Creek validate UNXE238 Corp’s expertise in identifying and developing multi-million-pound uranium assets in America’s premier uranium districts. Our team’s technical vision recognizing the significance of Kerr- McGee’s historical work and assembling this strategic land position is now being proven by drill bit.
With consistently strong results across 42 holes and Grade Thickness values well above industry standards, Duck Creek is demonstrating the potential to become a significant ISR uranium development in the Powder River Basin. As 100% owners until all option commitments are met, we are well-positioned to benefit from the continued advancement of this exceptional project.”
UNXE238 Corp Management
UNXE238 Corp's Expanding Uranium Portfolio
The success at Duck Creek reflects UNXE238 Corp’s proven methodology for identifying and developing high quality uranium assets. The Company has applied this same disciplined approach to assemble additional projects with significant exploration potential across Wyoming’s premier uranium districts:
Partnership and Investment Opportunities
UNXE238 Corp welcomes discussions with qualified partners and investors seeking exposure to high-quality uranium exploration assets in the United States. The Company’s portfolio of projects each featuring known mineralization, historical drilling data, and ISR development potential offers multiple pathways for value creation in the strengthening uranium market. With U.S. nuclear power plants requiring 45-50 million pounds of U₃O₈ annually and domestic production currently below 1 million pounds, the strategic importance of American uranium assets has never been greater. UNXE238 Corp is positioned at the forefront of this critical energy security opportunity. Interested parties are encouraged to contact UNXE238 Corp to explore potential partnerships, joint ventures, or investment opportunities across our portfolio of uranium exploration projects.
Technical Note
The geophysical results referenced herein are based on equivalent uranium (eU₃O₈) from gamma-ray probes calibrated at the Department of Energy’s Test Facility in Casper, Wyoming. All holes drilled are vertical and geological units are essentially flat, so intercept widths are interpreted as true thickness. The Exploration Target is conceptual in nature and does not meet the standards to be classified as mineral resources or reserves.
