Appointment of Executive Chairman

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 the appointment of Ivan Murphy as Executive Chairman with effect from 1 October 2025.

In his capacity as Non-Executive Chairman of Harena Ivan has led the Company's recent financial restructuring and strategic repositioning. The board of directors of Harena (the "Board" or the "Directors") are delighted to announce that he will now transition into an executive leadership role to drive the next phase of the Company's development. This will allow Executive Technical Director, Alan Mulligan, to dedicate his efforts to the forthcoming licence submission and the technical and environmental programmes required as the Ampasindava Project advances towards production.

As Executive Chairman, Ivan will continue to focus on strengthening the Company's engagement with existing and prospective stakeholders in the United States as well as advancing the Company's strategy to access U.S. capital markets. As part of this, and as announced on 16 September 2025, the Company has commenced the process to publicly cross-trade on the OTCQB Venture market, which is expected to provide the opportunity for U.S. investors to invest in the Company.

The Board recognises the importance of broadening the executive team and this process is underway. Updates on further executive appointments will be provided in due course.

Ivan Murphy, Non-Executive Chairman of Harena, said:

"I look forward to transitioning to the role of Executive Chairman of Harena having had such a long-standing relationship with the Ampasindava Project. In addition, I look forward to working closely with the Board as we advance the Ampasindava Project towards production. With a 600,000-tonne ionic clay, free-dig, magnet metal heavy rare earth resource, Harena offers a unique and strategic opportunity at a time when mineral security is increasingly prioritised across the U.S. and the western world."
