UNXE238 Corp Advances Strategic Partnership on Duck Creek Uranium Project in Wyoming's Premier Powder River Basin
June 19, 2025 – El Paso, Texas
Over 4000 Historic Drill Holes Defining a N-S Oriented Uranium Trend in One of America’s Most Productive ISR Mining Districts
June 19, 2025 – El Paso, Texas – UNXE238 Corp., (“UNXE238” or the “Company”) a uranium exploration and development company, is pleased to announce that it has entered into a property option agreement with Noble Plains Uranium Corp (TSX-V: NOBL, OTCQB: NBLXF, FSE: INEN), (“Noble Plains”) under which Noble Plains will acquire an 80% interest in the strategically located Duck Creek Project in Wyoming’s highly productive Powder River Basin.
UNXE238 Corp. holds the Duck Creek Project, a brownfield uranium asset spanning 4,133 acres (6.5 square miles) of mineral rights. The Project is situated amidst major in-situ recovery (ISR) uranium operations, including those owned by Uranium Energy Corp., Cameco Corporation, and GTI Energy Limited (Fig. 1). This prime location, combined with extensive historic drilling and shallow roll-front uranium mineralization, underscores the Project’s exceptional prospectivity and strategic value.
Prime Uranium Jurisdiction, Powder River Basin, Wyoming
Since the 1950s, Wyoming has been a major contributor to U.S. uranium production, yielding more than 238 million pounds to date. At the heart of this legacy lies the Powder River Basin (PRB), a cornerstone region for uranium extraction. Today, in-situ recovery (ISR) has become the predominant mining method in both the PRB and the broader state, offering a cost-effective and environmentally responsible approach. The Duck Creek Project is ideally positioned to benefit from this modern, low-impact technique, which supports streamlined permitting, reduced surface disruption, and lower development and operating expenditures—making it a compelling opportunity for sustainable uranium advancement
With over 4000 historic drill holes delineating a 3-mile-long mineralized corridor within the Eocene Wasatch Formation, Duck Creek is a compelling uranium system with mineralization from less than 50 feet to 260 feet below surface (Fig. 2; Table 1). Evidence of historic open-pit production further highlights the Project’s significant resource potential.
“UNXE238 Corp. is proud to lead the development of the Duck Creek Project, a standout asset in one of America’s premier uranium districts,” said Munazzam Ali Mahar, Chairman of UNXE238 Corp. “Our partnership with Noble Plains enables us to accelerate advancement of this high-potential project by combining our foundational data and expertise with Noble Plains’ development capabilities.”

adjacent property’s owner on their official website.
The Powder River Basin remains a vital center for U.S. uranium production, and UNXE238 Corp.’s detailed evaluation confirms the continuity of near-surface mineralization and significant upside potential in the deeper, largely untested Fort Union Formation, which hosts resources in neighboring operations.
“This transaction represents a powerful combination of near-term development potential and long-term exploration upside, positioning UNXE238 Corp. at the forefront of uranium resource growth in this key district,” added Munazzam Ali Mahar.
A National Instrument 43-101 (“NI 43-101”) technical report, commissioned by UNXE238 Corp. and prepared by an independent Qualified Person, is nearing completion. The report will outline an exploration target for uranium mineralization based on the Project’s extensive historical drilling. UNXE238 Corp.’s technical team has thoroughly and diligently evaluated the substantial drillhole database—comprising over 4000 historical holes—and has completed detailed modeling of key mineralized zones. This comprehensive work has confirmed both the integrity of the data and the significant uranium potential at Duck Creek. Confirmation drilling is planned for later this year to advance the Project toward an initial NI 43-101 compliant resource estimate.
UNXE238 Corp. has entered into a definitive property option agreement (the “Agreement”) with Noble Plains Uranium Corp., dated June 13, 2025. Under the agreement, Noble Plains may acquire up to an 80% interest in UNXE238’s wholly held Duck Creek Uranium Project, located in Wyoming’s Powder River Basin, over a three-year earn-in period.
In recognition of the significant historical work, geological data, and strategic positioning secured by UNXE238 Corp., the agreement outlines the following consideration:
- Within seven days of TSX Venture Exchange approval:
o A cash payment of US$250,000 to UNXE238 Corp.;
o Full reimbursement of staking and Bureau of Land Management (BLM) fees;
o Issuance of 1,250,000 common shares of Noble Plains Uranium Corp.
- On or before the first anniversary of the agreement:
o A further US$ 300,000 in cash;
o An additional 1,500,000 shares, or US$ 200,000 in cash at UNXE238’s option.
- On or before the second anniversary:
o A further US$ 450,000 in cash;
o Another 1,500,000 shares, or US$300,000 in cash at UNXE238’s option.
- On or before the third anniversary:
o A final payment of US$ 500,000;
o 1,250,000 shares, or US$ 400,000 in cash, Nobel Plains option.
Upon full exercise of the option, Noble Plains will earn an 80% interest in the Duck Creek Project, and the parties will enter into a joint venture agreement with UNXE238 Corp. retaining a 20% participating interest in the Project. In addition, UNXE238 will retain a 1% net smelter return (NSR) royalty on all future production from the Property. Unless Nobel Plains fulfill all the commitment, project will remain UNXE238 Corp’s property.
