Notes to editors

Harena (www.harenaresources.com) is a rare earths exploration and development company focused on the Ampasindava Ionic Clay Rare Earth Project in Madagascar (Harena's interest is 100%). The project hosts one of the largest ionic clay rare earth deposits outside of China, with significant concentrations of high-value magnet metals, specifically heavy rare earths, including neodymium (Nd), dysprosium (Dy), and praseodymium (Pr), which are critical for the composition of neodymium magnets (NdFeB). Harena is committed to low-impact, high recovery mining, providing a sustainable supply of critical minerals for the global energy transition and military defence industries as well as meeting the ever-growing demand for NdFeB from the robotics sector.

CHAIRMAN'S STATEMENT

It gives me great pleasure to present this year's Annual Report and Accounts for Harena Rare Earths PLC, marking a period of substantial progress and growing momentum as we advance the Ampasindava Ionic Clay Rare Earth Project (the "Project") in Madagascar towards production.

2025 has been a transformative year for the Company. In February 2025 the Company completed the acquisition of Harena Resources Pty Ltd, the owner of the Project and changed its name to Harena Resources PLC. On 27 October 2025 the Company changed its name from Harena Resources PLC to Harena Rare Earths PLC.

Since then, we have advanced our globally significant 606,000 tonne TREO JORC-compliant resource, which includes a premium mix of heavy rare earth elements such as dysprosium, terbium, neodymium, and praseodymium, all critical to the world's transition to clean energy, high-performance technologies, and advanced defence systems.

Our Project is not an exploration play; it is a true mining project with a clear development pathway. Following the completion of baseline metallurgical test work and our Pre-Feasibility Study scheduled for November 2025, we will move quickly into a Feasibility Study in early 2026. This will support the conversion of our mining licence application, expected in 2026, as we continue our active and constructive engagement with the Malagasy government and local stakeholders.

A particularly important milestone in this period has been the strong financial support we have secured from leading institutions in both the UK and the US, including Wexford Capital, Fondren LLP, and RAB Capital. As a result of these fundings, Harena is now financially secure to meet its near-term costs, giving us the confidence and stability to accelerate the Project on its path towards production.

In July 2025, the Company successfully completed a £1,231,500 institutional placing to advance the Project, receiving strong support from both new and existing investors and enabling progress on the Pre‑Feasibility Study, environmental workstreams, and early-stage development activities.

Subsequently, in October 2025, the Company announced a further £450,000 strategic investment from RAB Capital and associates, increasing RAB's shareholding to approximately 9%, via a convertible loan agreement where the shares cannot be issued until January 2026. Led by Philip Richards, one of London's most respected and long‑standing mining investors, RAB Capital has a distinguished track record of identifying value and supporting growth in the mining sector. This additional investment represents a strong endorsement of our strategy and provides further financial strength as we continue to advance our world-class ionic clay rare earth project toward production.

Harena occupies a truly unique position in the market. We are the only pure ionic clay rare earth company listed on the London Stock Exchange, offering one of the very few large-scale ionic clay deposits outside China. This positions us as a vital strategic partner in strengthening resilient, transparent, and geopolitically neutral supply chains for critical rare earth elements.

The U.S. Government has made clear its determination to secure critical mineral supply chains and reduce reliance on China for rare earth elements. Harena is exceptionally well placed to be part of this solution, with a development-ready, ex-China ionic clay deposit that can deliver the heavy rare earths essential for defence, energy, and technology applications. It is our stated strategy to increase our engagement with U.S. government agencies as we move towards production.

In line with this strategy, we are also advancing an OTC cross-trade of our shares in the United States. This represents the first step in opening access to U.S. capital markets and enabling American investors to participate directly in the Group's growth, while continuing to trade on the London Stock Exchange.

Looking ahead, we expect 2026 to be another pivotal year. Completion of our Feasibility Study, the expected upgrade of our licence, and ongoing progress with our government and community partnerships will continue to de-risk and advance the Project. From 2027 onwards, we will transition towards project financing, construction, and ultimately, first concentrate shipments targeted for 2028.

On behalf of the Board, I would like to thank our shareholders, partners, and stakeholders for their continued support. With the financial backing now in place, a globally significant resource, and a motivated and experienced management team, Harena is exceptionally well positioned to deliver long-term value and to play a crucial role in securing the future of critical mineral supply chains.
