• Preparations underway for commencement of a resource expansion diamond drilling program at the Gronnedal Rare Earth Project in September 2025
• Rubidium (Rb) and Gallium (Ga) identified in Ivigtut drill core sample and mineralised stockpiles, with Rb and Ga on the US Critical Minerals List
• Multiple catalysts in the pipeline including drilling commencement, mineralogical studies, potential by-product pathways for Rb and Ga, and ongoing stakeholder engagement in Greenland

Eclipse Metals Ltd (ASX: EPM) is pleased to announce that preparations are advancing for the commencement of a resource expansion diamond drilling program at the Gronnedal Rare Earth Project in Greenland during September 2025. The upcoming drilling program is designed to build on Eclipse's recently reported JORC-compliant Inferred Mineral Resource Estimate of 89Mt @ 6,363 ppm TREO (567,600t TREO), which has already established Gronnedal as one of the largest identified rare earth resources in the North Atlantic region. Diamond drilling will target deeper extensions of the carbonatite complex as well as high-priority anomalies identified in previous geophysical and mineralogical work, with the objective of expanding and upgrading the current resource base.In parallel, Eclipse has received assay results from Ivigtut stockpiles of mineralised waste confirming consistent enrichment in Rubidium (Rb) and Gallium (Ga); two minerals that are recognised by the US Government as critical to high-tech and defence supply chains. These results follow up on the discovery of Rb and Ga in an archival core sample obtained from below the Ivigtut Open Pit. The combination of a large-scale rare earth resource at Gronnedal with critical co-elements (Rb and Ga at Ivigtut) underscores Eclipse's strategic positioning within the North Atlantic supply chain. With port access at Ivigtut, proximity to European markets, and alignment with the EU Critical Raw Materials Act and US Critical Minerals strategy, Eclipse believes it is uniquely placed to attract global partnerships as supply chains continue to pivot away from reliance on China.

Eclipse Metals is advancing multiple catalysts in the pipeline, including the commencement of the resource expansion drilling program at Gronnedal, mineralogical studies to refine understanding of Rb and Ga host phases, assessment of by-product pathways for Rb and Ga recovery, and ongoing stakeholder engagement with Greenlandic authorities and communities to support sustainable project development.
