  Expands U.S. Uranium Portfolio to Advance Clean Energy Transition

Metals One (AIM: MET1), a minerals exploration and development company, is pleased to announce the completion of its acquisition of the Squaw Creek Claims (the "SQ Claims") in Carbon County, Wyoming, United States which hold the Squaw Creek Uranium Project as originally announced on 24 April 2025. The SQ Claims represent the Company's second uranium project in the U.S., and complement the recently completed acquisition of the Uravan Uranium-Vanadium Project in Colorado, as announced on 2 July 2025.

Highlights

·    Strategic Addition in Premier Uranium Jurisdiction: The SQ Claims comprise 53 unpatented mining claims (~430 hectares) in Wyoming's Shirley Basin, one of the most historically productive uranium regions in the U.S., with established ISR (In Situ Recovery) mining operations.

·    Proximal to Advanced Nuclear Infrastructure: Located near historical uranium operations and TerraPower's next-generation nuclear reactor project, the SQ Claims are strategically situated to support U.S. nuclear energy security goals.

·    Phase 1 Exploration Underway: Initial geophysical surveys and surface sampling are ongoing as part of the Company's Phase 1 uranium exploration programme in the U.S., which includes both the Uravan and SQ projects.

Transaction Terms

Metals One has acquired 100% of the SQ Claims from the vendor, 1491434 B.C. Ltd., under the terms of an asset purchase agreement. The consideration comprises:

·    US$50,000 in cash; and

·    The issuance of 500,000 new ordinary shares in Metals One Plc at a price equivalent to a 5% discount to the five-day volume-weighted average price (VWAP) immediately prior to execution, being 19.0363 pence per share.

All necessary approvals have now been obtained, including the issue of the 10-year exploration lease, and the transaction is complete.

Strategic Rationale

The acquisition of the SQ Claims further consolidates Metals One's position in the U.S. uranium sector, aligned with the Company's strategy to advance critical mineral assets essential to the clean energy transition. The Shirley Basin is recognised for its ISR-amenable uranium mineralisation and is home to multiple historic production sites. With uranium demand forecast to rise amid global nuclear energy expansion and increasing geopolitical focus on domestic supply, the Company sees significant long-term value in these U.S.-based assets.

Craig Moulton, Chair of Metals One, commented:

"We are pleased to have completed our second outright U.S. uranium acquisition in the Shirley Basin, Wyoming, following our successful acquisition in Colorado. This follows our entry into the Red Basin, New Mexico, via NovaCore Inc last week also. We continue to build momentum with our North American strategy and this positions us to advance exploration across three highly prospective districts with strong historic uranium pedigree and near-term exploration upside."

Admission to Trading and Total Voting Rights

Application will be made for the admission of the 500,000 consideration shares to trading on AIM ("Admission"), expected to take effect at 8.00 a.m. on 25 July. Following Admission, the Company's issued share capital will consist of 368,647,750 ordinary shares with voting rights. The figure of 368,647,750 may be used by shareholders for FCA's Disclosure Guidance and Transparency Rules calculations.
