Additional Investment in Uranium Venture, USA

Metals One Increases NovaCore Stake to 35% to Accelerate Maiden Drilling

at Red Basin Uranium Project, New Mexico

Further to the Company's investments announced on 18 and 29 July 2025, Metals One (AIM: MET1), a minerals exploration and development company with key interests in uranium and gold projects, is pleased to announce it has agreed to increase its shareholding in NovaCore Exploration Inc. ("NovaCore"), a private U.S.-based company advancing the large-scale Red Basin Uranium Project, from its current 30% to 35% by way of cash subscription of approximately US$297,000. This brings the Company's investment in NovaCore to date to approximately US$1.45 million.

Metals One's additional investment is designed to enable NovaCore to accelerate its plans to conduct a maiden drilling campaign at the large-scale Red Basin Uranium Project in Catron County, New Mexico, anticipated to commence in Q4 2025.

Project Overview

As previously announced, NovaCore holds approximately 15,000 acres in the Red Basin Uranium District of New Mexico, where historical U.S. Department of Energy assessments and recent radiometric surveys suggest there is potential for 40 million pounds of U₃O₈. Recently, NovaCore's gamma spectrometry surveys have identified multiple uranium-rich zones. The area has road access, a known permitting regime, and favourable geology with structural and geophysical targets that remain largely undrilled below 400 feet.

NovaCore has completed land staking, radiometric and geophysical surveys, and is advancing permitting and environmental studies to support forthcoming drilling.

NovaCore's board of directors includes Neil Herbert (Founder and Chairman) and Douglas Christopherson (Founder and Technical Advisor) both of whom played key roles in the management of AIM and TSX listed Uramin Inc. which was sold for US$2.5 billion.

Further information on the drill programme will be announced in due course.

Craig Moulton, Chairman of Metals One, commented:

"This investment in NovaCore's Red Basin project will deliver Metals One's first exposure to a high-impact uranium drilling campaign. We are gaining access to one of the most prospective yet underexplored uranium districts in the western U.S. with the potential to host future uranium deposits of national importance."
