Noble Plains Uranium intersects uranium in all drill holes at Shirley Central

Vancouver, British Columbia--(Newsfile Corp. - August 10, 2026) - Noble Plains Uranium Corp. (TSXV: NOBL) (OTCQB: NBLXF) (FSE: INE0) (" Noble Plains " or the " Company ") a U.S.-focused uranium exploration and development company, is pleased to announce the results of the recently completed seven-hole confirmation drill program at its Shirley Central Project in Wyoming's prolific Shirley Basin. The program successfully intersected uranium mineralization in every hole drilled, confirming the presence and continuity of mineralization interpreted from the Company's extensive historical database and validating Noble Plains' data-driven approach to the project.

Highlights

The seven-hole confirmation drill program was a success: uranium mineralization was intersected in all seven holes drilled. Mineralization was encountered in the Upper, Main and Lower Sand.

The results confirm the mineralization Noble Plains had already mapped from its compiled database of more than 1,211 historical drill holes, validating the Company's data-driven, brownfield-conversion approach.

High-grade intercepts were returned, including 2 ft of 0.389% eU₃O₈ in hole 26-17-06 and 2 ft of 0.208% eU₃O₈ in hole 26-03-03.

The results position Shirley Central as a second Wyoming project that can advance toward a mineral resource estimate (MRE), adding to Noble Plains' asset base and increasing the Company's leverage to a rising uranium price.

Shirley Central sits directly adjacent to Ur-Energy's Shirley Basin operation – the newest uranium mine in the United States. Ur-Energy is a shareholder of Noble Plains and has signed a non-binding letter of intent to potentially process future Shirley Central production at its nearby facilities.
