First Tranche of Ambeon Option Exercised

Capital Metals (AIM: CMET), a mineral sands company approaching mine development stage at the high-grade Taprobane Minerals Project in Sri Lanka (the "Project"), is pleased to announce it has received subscriptions for approximately the first ~US$825,000 of investments pursuant to the US$2 million Ambeon Option as announced on 29 May 2025.

Ambeon has advised the Company that it has exercised its right to assign the option in parts to third parties who have now subscribed in aggregate for 22,713,704 new Ordinary shares in the Company ("First Tranche Subscription Shares") at an issue price of 2.75 pence per share.

Ambeon has further informed the Company that it expects to secure the balance within the Ambeon Option period which was extended to 11 August 2025 (as announced on 16 July 2025) and therefore intend to exercise the Ambeon Option in full.

The proceeds will be used to obtain all necessary approvals to reach FID, with any amounts remaining to be used for general working capital and applied towards capital expenditure in connection with Stage 1 of the Project.

Greg Martyr, Executive Chairman of Capital Metals, commented:

"We have been working effectively with Ambeon to ensure the US$2 million option is exercised in full to achieve the total US$4 million strategic investment as announced in late May. We look forward to finalising the Ambeon Option and working together towards the development of the Project, cementing a funding path to positive cash flow."
