Highlights
- Eclipse Metals identifies strong gallium and rare earth element (REE) mineralisation at the Grønnedal prospect in Greenland.
- Bulk samples from waste dumps reveal gallium concentrations averaging 39.16 ppm and other valuable minerals.
- Rare earth mineralisation spans a 5 km by 2 km area, with promising depth potential exceeding 500 metres.
Eclipse Metals Ltd (ASX:EPM) continues to uncover promising polymetallic mineralisation at the Grønnedal prospect, part of its broader Greenlandic project near the historic Ivigtût cryolite mine. The company has reported significant findings of gallium and rare earth elements (REE), further cementing the area’s potential as a valuable resource hub.
Gallium Discovery from Waste Dumps
Recent analysis of bulk samples collected from historical mineralised waste dumps has confirmed elevated concentrations of gallium, with results showing up to 43.1 parts per million (ppm) and an average of 39.16 ppm across five samples. Gallium, a key material for emerging technologies such as semiconductors and solar cells, positions Ivigtût as a potential contributor to the global gallium supply outside of China.
The samples were obtained through trenching in waste dumps, blended, and analyzed using the ME-MS61 method. This approach validated the presence of gallium alongside other valuable elements such as:
- Silver: Up to 16.55 ppm.
- Copper: Up to 538 ppm.
- Zinc: Up to 3,180 ppm.
- Lead: Up to 2,650 ppm.
Rare Earth Element Potential
At Grønnedal, historical airborne electromagnetic surveys and ongoing laboratory analysis point to deep-seated rare earth mineralisation with depth potential exceeding 500 metres. Initial findings have identified neodymium, praseodymium, dysprosium, and terbium among key medium rare earth elements (MREE), essential for applications in renewable energy, electric vehicles, and magnets.
Preliminary results from historical diamond drill cores and surface sampling efforts further validate the continuity of REE mineralisation from surface to depths of at least 200 metres. Notably, the aerial extent of the mineralisation covers a 5 km by 2 km area, with an immediate focus on a 3 km by 800 metre ferrocarbonatite zone.
Path Forward: Drilling and Resource Expansion
Eclipse Metals plans follow-up drilling to test conductive targets identified through recent surveys and laboratory analysis. These efforts aim to unlock additional resource areas and confirm the continuity of mineralisation at depth.
The company’s exploration program is buoyed by consistent neodymium ratios observed in preliminary results, reinforcing the potential for significant resource expansion. This consistency aligns with findings from previous drilling and surface sampling campaigns.
Strategic Importance of Grønnedal
Grønnedal’s strategic location and mineral richness position it as a critical area for Eclipse Metals’ exploration efforts. The discovery of high-value minerals such as gallium and REEs underscores its importance in supporting future-facing industries like renewable energy and advanced technologies.
With ongoing analysis and planned drilling campaigns, Eclipse Metals continues to advance its mission of unlocking the full potential of the Grønnedal prospect, contributing to the growing demand for rare earth elements and other critical minerals.
