Issue of Equity & TVR

Cash Warrants Financing Substantially Completed - Company Fully Funded to Advance Projects

Metals One (AIM: MET1), a minerals exploration and development company with key interests in uranium and gold projects, announces it has received notice of the exercise of Cash Warrants, issued pursuant to the Equity Fundraise announced on 31 January 2025, over a total of 93,000,000 ordinary shares in the Company (the "Warrant Shares") at 2 pence per share. This substantially completes the Cash Warrant exercises (with only 850,000 Cash Warrants outstanding) and therefore concludes the Equity Fundraise.

Additionally, the Company has issued 380,000 ordinary shares at a price of 5 pence per share to settle a deferred consideration obligation under the sale and purchase agreement dated 23 May 2023 (as amended on 26 June 2023 and 24 July 2023 and set out in the Company's Admission Document available at https://metals-one.com/investors/) pursuant to which Metals One acquired Scandinavian Resource Holdings Pty Ltd (and gained its interest in the Råna Nickel Project in Norway) (the "Consideration Shares").

Application will be made for the admission of the Warrant Shares (pursuant to the authorities approved by shareholders at the General Meeting on 25 March 2025) and the Consideration Shares to trading on AIM. The Warrant Shares and the Consideration Shares will rank pari passu with the existing ordinary shares and it is expected that admission will become effective at 8.00 a.m. on 20 August 2025.

Following admission of the Warrant Shares and Consideration Shares, the Company's issued share capital will consist of 839,946,460 ordinary shares with voting rights. Metals One does not hold any ordinary shares in treasury. This figure of 839,946,460 may be used by shareholders in the Company as the denominator for the calculations by which they will determine if they require to notify their interest in, or a change to their interest in, the share capital of the Company under the UK Financial Conduct Authority's Disclosure Guidance and Transparency Rules.

Craig Moulton, Chair of Metals One, commented:

"Through the Equity Fundraise, which completed in April, and the associated Cash Warrants, Metals One has undergone a transformational refinancing, allowing us to make opportunistic investments and broaden our commodity exposure, with a strategic weighting to uranium and gold. I believe the Company now offers exposure to a range of quality exploration opportunities in reliable jurisdictions with significant exploration upside potential. We are now fully funded to advance our projects and business development strategy."
