How Eclipse Metals’ Magnetic Tests Could Unlock Greenland’s Rare Earths Potential
Eclipse Metals has initiated metallurgical testing on its Grønnedal Rare Earths Project in Greenland, focusing on magnetic separation techniques to unlock the deposit’s potential. Core samples from recent drilling are en route to Perth for analysis, while strategic engagement with global partners continues.
- Preliminary Wet High-Intensity Magnetic Separation (WHIMS) tests underway
- Seven composite samples from historic drilling submitted for analysis
- 2025 diamond drill core samples dispatched to ALS Laboratories in Perth
- Initial magnetic mass pulls of up to 86% recorded, assay results pending
- Active engagement with US, EU, Denmark, and Greenland on critical minerals supply chains
Metallurgical Testing Kicks Off
Eclipse Metals Ltd (ASX – EPM) has taken a significant step forward in developing its Grønnedal Rare Earths Project in southwestern Greenland by commencing preliminary metallurgical test work. The focus is on Wet High-Intensity Magnetic Separation (WHIMS), a technique that exploits magnetic differences to separate valuable minerals from waste. This early-stage testing uses seven composite samples derived from historic drill cores, providing a consistent baseline to refine processing flowsheets.
The composite samples, weighing between 1.25 and 4.5 kilograms, represent various parts of the Grønnedal deposit. Initial sighter tests at magnetic field strengths of around 7,000 Gauss have yielded encouraging magnetic mass pulls of 78% and 86% for two composites, indicating a strong potential for efficient separation of rare earth elements (REEs). However, the critical assay results that will reveal how much of the REE content reports to the magnetic fractions are still awaited.
New Drill Core Samples En Route
Complementing the composite-based work, Eclipse has also processed core samples from its 2025 diamond drilling campaign. These samples have been logged, cut, and dispatched to ALS Laboratories in Perth for detailed chemical analysis. The results from these fresh drill cores will provide a more representative understanding of the deposit’s metallurgical characteristics and help guide subsequent test work.
Strategic Positioning in Critical Minerals Supply
Beyond the technical progress, Eclipse is actively engaging with stakeholders across the United States, European Union, Denmark, and Greenland. The company aims to align its project development with the growing global imperative to secure critical minerals supply chains that are independent of China. This strategic outreach underscores the geopolitical significance of rare earth projects like Grønnedal and positions Eclipse as a trusted partner within allied jurisdictions.
Notably, the Greenland Government recently renewed Eclipse’s exploration licence MEL 2007-45, now named Kamittalik, extending it through to the end of 2027. This regulatory certainty provides a solid foundation for ongoing exploration and development activities.
Looking Ahead
Eclipse Metals anticipates further updates as assay data from the WHIMS test fractions and the 2025 drill core analyses become available. These results will be pivotal in confirming the deposit’s amenability to magnetic separation and refining the processing strategy. Meanwhile, the company’s proactive engagement with international partners signals its intent to play a key role in emerging non-China-aligned rare earth supply initiatives.
Bottom Line?
As assay results and strategic discussions unfold, Eclipse Metals is poised to sharpen its rare earths project’s competitive edge in a geopolitically sensitive market.
Questions in the middle?
- Will assay results confirm efficient REE recovery through WHIMS magnetic separation?
- How will Eclipse’s strategic engagements influence project financing and partnerships?
- What are the next steps in scaling metallurgical testing towards pilot plant or production?
