Noble Plains Uranium (OTCQB: NBLXF) has expanded its Shirley East Project in Wyoming's Shirley Basin through the staking of 16 new mineral claims covering 320 acres. The newly staked claims are strategically positioned adjacent to Uranium Energy Corp (UEC) properties and are supported by historical data showing over 174 drillholes from the 1980s indicating zones of higher uranium mineralization.

The expansion strengthens Noble Plains' position in the Shirley Basin, which historically produced over 51 million pounds of uranium between 1960 and 1992. The company's holdings now include both Shirley Central and the expanded Shirley East project, with field programs and permitting in progress for planned drilling in 2025.

Vancouver, British Columbia--(Newsfile Corp. - July 23, 2025) - Noble Plains Uranium Corp. (TSXV: NOBL) (OTCQB: NBLXF) (FSE: INE0) ("Noble Plains" or the "Company") is pleased to announce that it has staked an additional 16 mineral claims covering approximately 320 acres on the eastern side of its existing Shirley East Project in Wyoming's Shirley Basin.

This strategic expansion increases Noble Plains' footprint in one of the most historically productive and actively resurging uranium districts in the United States. The newly staked claims are located directly adjacent to lands held by Uranium Energy Corp (UEC) and are underpinned by historical aerial data showing over 174 drillholes. The tight clusters of past drilling activity—strongly correlated with zones of higher uranium mineralization in the 1980's, are the key target areas of the newly staked projects.

"This staking expands our presence in a district that has already proven its value," said Paul Cowley, CEO of Noble Plains Uranium. "We identified this area through historical aerial datasets that revealed concentrated legacy drill patterns. These patterns are closely associated with higher mineralized zones and staking these claims allows us to consolidate a highly prospective area next to a major uranium player."

The Shirley Basin produced over 51 million pounds of uranium between 1960 and 1992 and is now seeing a resurgence in development and investment. By extending the Company's existing project area, Noble Plains not only strengthens its land position but also unlocks exploration efficiencies—leveraging permitting, logistics, and future resource delineation across a broader claim package.

This expansion is consistent with the Company's focused strategy: to build a pipeline of uranium pounds in the ground by targeting brownfield and historically mineralized projects in top-tier U.S. jurisdictions with ISR (In-Situ Recovery) potential.

Noble Plains' Shirley Basin holdings now include the Shirley Central and the expanded Shirley East project growing the companies footprint with both near-term drill targets and long-term growth potential. The Company is actively advancing multiple properties across Wyoming's Powder River and Shirley basins, with field programs and permitting underway for planned drilling in 2025.
