Harena Rare Earths plc

("Harena" or the "Company")

Mining Terms and Conditions (CCM) Signed - Clearing the Path to Pilot Plant and Environmental Permitting at Ampasindava

Harena Rare Earths plc (LSE: HREE, OTCQB: CRMNF), advancing the Ampasindava ionic clay rare earth project in Madagascar (the "Ampasindava Project"), is pleased to report a major regulatory milestone.

Highlights

The signature of the CCM confirms Ampasindava as one of the few large-scale ionic clay rare earth projects being advanced outside China, with the potential to become a significant source of the magnet rare earth elements neodymium, praseodymium, dysprosium and terbium - supporting the diversification of global critical mineral supply chains.

Ivan Murphy, Executive Chairman of Harena, commented:

"Signing the CCM is a defining regulatory milestone. It gives us a clear framework to advance responsibly in Madagascar and, critically, clears the path to our Proof of Concept pilot plant and onsite laboratory. With the recent DFC facility in place, we are funded to deliver the next phase of work - beginning with the environmental and social assessment, stakeholder engagement and public consultation that underpin our approvals. Before entering commercial production, we will be completing all permits and authorisation consistent with our environmental and social commitments as set out in our PFS.

I would like to thank the Ministry of Mines, the Bureau du Cadastre Minier de Madagascar, our local team and all our advisers and stakeholders for their continued support."
