Eclipse Metals (ASX: EPM) has reported encouraging Phase 1 WHIMS sighter test results from its Grønnedal rare earth element (REE) Project in Greenland, indicating strong magnetic amenability and supporting further optimization for Phase 2 testing.
Phase 1 Wet High-Intensity Magnetic Separation sighter tests demonstrated strong magnetic amenability, with 78-86% of the feed reporting to early magnetic fractions at 7000 Gauss.
Crucially, more than 90% of the iron deported to these magnetic fractions, resulting in a low final non-magnetic tail of just 3-4% of the total mass.
The neodymium (Nd) head assays across the seven composite samples tested ranged between 533 and 1,828 ppm, indicating a potentially simpler beneficiation pathway through staged magnetic separation.
The company plans further optimisation and Phase 2 representative testing using 2025 drill quarter-core samples.
Licence Renewal Secures Greenland Tenure
In further positive news for its Greenland operations, Eclipse Metals has successfully renewed its key mining licence MEL 2007-45.
This licence, now known as Kamittalik, has secured tenure for the company’s Grønnedal project until 31 December 2027.
The renewal included minor boundary adjustments to exclude a military zone, ensuring clarity on the operational footprint.
Strategic Engagement Targets US Funding
Eclipse Metals continues to proactively engage with international stakeholders, aiming to position its Greenland projects within Western critical mineral supply chains.
The company recently engaged BGR Group, a prominent US government relations firm to accelerate Eclipse’s Greenland rare earths strategy by pursuing engagement with the US Administration, federal agencies, and Congress.
The engagement seeks to guide financing pathways and foster Western-market partnerships, aligning with US strategic materials priorities.
Furthermore, Eclipse Metals is actively considering a NASDAQ dual-listing, a step that could broaden investor access and tap into US funding opportunities for its projects.
Resource Upgrade Reinforces Project Potential
These metallurgical and strategic advancements build upon a substantial resource upgrade at the Grønnedal project.
In June 2025, Eclipse Metals reported an Inferred Mineral Resource Estimate (MRE) of 89.2 million tonnes at 6363 ppm TREO, equating to 567,600 tonnes of Total Rare Earth Oxides.
Previous metallurgical testing on Grønnedal material had indicated promising results, showing up to 54% REE recovery via low-cost flotation methods.
Magnet rare earth elements (Nd, Pr, Dy, Tb), critical for high-tech applications, comprise 33-39% of the TREO within the resource.
The resource remains open in all directions, suggesting potential for further growth and expansion.
Outlook and Risks
Encouraging metallurgical results and licence renewal support the development pathway for Eclipse Metals' Greenland REE project.
The company is actively pursuing strategic partnerships and US government engagement to de-risk funding and development, building on a significant resource upgrade.
Investors will monitor Phase 2 metallurgical testing, regulatory progress, and the company's ability to secure future funding.
