Eclipse Metals Confirms Vast Rare Earth Mineralisation at Grønnedal
Eclipse Metals has completed over 700 metres of diamond drilling at its Grønnedal project in Greenland, confirming continuous rare earth mineralisation and reinforcing its substantial inferred resource estimate. Drilling has now progressed to the polymetallic Ivigtût prospect, broadening the company’s critical minerals footprint.
- 700+ metres of diamond drilling confirm continuous carbonatite mineralisation at Grønnedal
- Existing inferred resource of 89 million tonnes at 6,363 ppm total rare earth oxides supported
- Core samples show mineralogy typical of high-value rare earth elements including Nd, Pr, Dy, Tb
- Drilling underway at Ivigtût targeting polymetallic mineralisation including fluorite and base metals
- Strategic positioning in Greenland’s critical minerals sector with engagement towards U.S. capital markets
Drilling Success at Grønnedal
Eclipse Metals Ltd (ASX, EPM) has announced a significant milestone in its 2025 Greenland drilling campaign, completing over 700 metres of diamond drilling at the Grønnedal Rare Earth Element (REE) prospect. The drilling has confirmed continuous carbonatite mineralisation from surface to depths approaching 200 metres, validating previous trenching and historical core studies. This continuity is a crucial geological confirmation that underpins the project's existing inferred mineral resource estimate (MRE) of 89 million tonnes at 6,363 ppm total rare earth oxides (TREO).
Core observations reveal a complex carbonatite system enriched with hematite and magnetite, minerals commonly associated with rare earth elements such as neodymium, praseodymium, dysprosium, and terbium. These elements are critical for manufacturing high-strength permanent magnets used in electric vehicles, wind turbines, and advanced electronics, highlighting Grønnedal’s strategic importance.
Geological Insights and Resource Implications
The drilling program employed a Boart Longyear T800N diamond drill rig, capable of operating in Greenland’s challenging Arctic terrain. Core recoveries were near 100%, allowing detailed geological logging that confirmed the presence of alternating calcite and siderite-rich carbonatite zones with magnetite and hematite overprints. These textures and mineral assemblages are consistent with globally recognized REE-bearing carbonatite systems, reinforcing the project's potential for conventional processing methods.
While the current resource estimate covers only about 6% of the carbonatite body, the drilling results suggest a much larger mineralised system. Analytical assay results are expected in the first quarter of 2026, which will provide critical data to refine resource estimates and support future development planning.
Expanding Horizons at Ivigtût
Following the success at Grønnedal, Eclipse has advanced its drilling rig to the nearby Ivigtût prospect, approximately seven kilometres away. Unlike Grønnedal’s rare earth focus, Ivigtût hosts a polymetallic and industrial mineral system centred on the historic cryolite mine. Drilling here targets a diverse suite of minerals including fluorite, quartz, cryolite, galena, sphalerite, and siderite, with anomalous silver, zinc, copper, lead, gallium, and lithium also reported from bulk sampling.
This multi-commodity approach broadens Eclipse’s exposure within Greenland’s critical minerals sector, aligning with the country’s Mineral Resources Strategy 2025–2029, which encourages sustainable development and international investment in minerals essential for the energy transition.
Strategic Positioning and Market Outlook
Eclipse’s dual prospects in Greenland position the company as a notable player in the emerging critical minerals landscape. Executive Chairman Carl Popal emphasised the project’s geological simplicity and amenability to established processing flowsheets, key factors for attracting investment and advancing towards production.
Moreover, Eclipse is engaging strategically with U.S. advisory partners to explore capital market opportunities beyond its ASX listing, reflecting the geopolitical importance of rare earth supply chains for Europe and North America. Greenland’s favourable infrastructure and political support further enhance the prospects for these projects.
Bottom Line?
As assay results loom in early 2026, Eclipse Metals stands at a pivotal juncture to validate and potentially expand its rare earth resource in Greenland’s critical minerals arena.
Questions in the middle?
- What will the upcoming assay results reveal about the grade and distribution of rare earth elements at Grønnedal?
- How might Eclipse’s engagement with U.S. capital markets influence its funding and development timeline?
- What are the prospects for defining a resource and economic viability at the polymetallic Ivigtût prospect?
