Harena Resources Plc

("Harena" or the "Company")

Further Investment from RAB Capital and associates

The Board of Harena Resources Plc (LSE: HREE), the rare earths company focused on the Ampasindava ionic clay rare earth project in Madagascar (the "Ampasindava Project"), is pleased to announce terms for an investment of £450,000 into the Company by RAB Capital and associates ("RAB").

The investment is structured as a conditional subscription (the "Subscription") for the issuance of 30,000,000 new ordinary shares of £0.005p each in the Company (the "Subscription Shares") at a price of £0.015 per Ordinary Share.

This investment will increase RAB's shareholding in Harena from 4.17% to approximately 9.02% of the Company's enlarged issued share capital.

The proceeds from the Subscription will be used for working capital to advance the Ampasindava Project.

The issuance of the Subscription Shares is conditional, inter alia, upon the renewal of the directors' authority to issue ordinary shares at the Annual General Meeting of the Company in November 2025 and compliance with the Prospectus Rules.  An application will be made in due course for the Subscription Shares to be admitted to the Official List of the FCA and to trading on the Main Market of the London Stock Exchange when the shares are issued following the new Prospectus rules coming into effect (expected around 19 January 2026).
