Eclipse confirms high-value, coarse-grained rare earths at Grønnedal, backed by an efficient processing pathway

Eclipse Metals Limited (ASX: EPM) (Eclipse or the Company) is pleased to confirm that its Grønnedal rare earth elements (REE) Project in southwest Greenland continues to solidify its position as a strategically important and globally significant source of REE. The Project metrics are supported by robust scientific data and including benchmarked mineralogical results.

Project Highlights:

  • Dominant synchysite, bastnasite and monazite mineralogy - ideal for Nd-Pr permanent magnet feedstock.
  • Coarse-grain size of key REE minerals with up to 54% liberation, supporting low- cost, conventional flotation pathways.
  • The defined resource of 89Mt represents approximately 6% of the carbonatite body, with extensive growth potential.
  • Niobium ~4,670ppm, Yttrium ~777ppm, and HREE credits enhance the Project’s overall economics.
  • Tier-1 Greenland location with deep-water access and no uranium permitting constraints.
  • Mineralogical studies provide a strong foundation for upcoming metallurgical and process design work.

A recent mineralogical study completed by SGS Canada has confirmed the presence of high-value rare earth minerals, including Synchysite, Bastnasite and Monazite – highly sought-after hosts of magnet rare earth elements (Nd, Pr, Dy, Tb).

The recent mineralogical assessment returned significantly elevated niobium grades, ranging from <40ppm to 4,670ppm, and yttrium values ranging from 39ppm to 777ppm (refer Appendix 1), highlighting the polymetallic nature of the mineralisation and its potential for enhanced downstream value capture.

Both elements are increasingly sought after for superconductors, defence alloys, and advanced electronics, further elevating Grønnedal’s importance within the global critical minerals ecosystem.

Importantly, the test work confirms that the mineral assemblage is highly amenable to conventional processing, aligning with proven flowsheets successfully applied at other globally recognised REE operations, including Mountain Pass (USA) and Mount Weld (Australia).

Commenting on the SGS mineralogical results, Eclipse Metals Executive Chairman Carl Popal said:

“The Grønnedal REE complex continues to deliver compelling results that reinforce its emerging position as a globally strategic rare earths project. With 89 million tonnes now defined, the combination of scale, favourable mineralogy, coarse grain size and demonstrated processability sets Grønnedal apart as one of the few Western rare earth deposits with a clear pathway toward scalable development.

“The polymetallic nature of the mineralisation, combined with high liberation rates confirmed through advanced mineralogical studies, supports the potential for efficient recovery using well- established processing routes, further strengthening Grønnedal’s relevance to EU and North American critical minerals supply chains.

“Eclipse remains committed to responsible and transparent development in Greenland while advancing the project with a disciplined focus on value creation and global supply chain diversification,”

Expert: Can a United Front Loosen China’s Rare Earths and Critical Minerals Hold?

As western automakers reel from yet another round of Chinese export restrictions on rare earths, the urgency to create a counterweight to Beijing’s dominance over global mineral supply chains is reaching new heights.

At the center of the conversation is a persistent and disruptive strategy: Chinese state-backed firms flood global markets with critical minerals, push prices below sustainable production levels and wipe out foreign competition.

In response, experts like Gracelin Baskaran, director of the Critical Minerals Security Program at the Center for Strategic and International Studies, are calling for a fundamentally different playbook.

Burgum Endorses Colosseum Rare Earths Project in Continued Critical Minerals Push

The Trump administration is fast tracking development of Dateline Resources’ (ASX:DTR,OTC Pink:DTREF) Colosseum rare earths project in California as part of its push to boost domestic critical minerals supply.

In a recent interview, Secretary of the Interior Doug Burgum highlighted the project as a priority under the government's critical minerals strategy, stating that the US has "to get back in the game in a serious way around critical minerals.”

For his part, US President Donald Trump has called the project "America’s second rare earths mine.” He first announced Colosseum's approval in an April 21 Truth Social post, listing it as a weekly achievement.

Australian Strategic Reports Bump in Rare Earths Sales Enquiries

Australian Strategic Materials (ASX:ASM,OTC Pink:ASMMF) has confirmed the sale of neodymium and praseodymium (NdPr) metal and neodymium-iron-boron (NdFeB) alloy to its key partners.

Supply came from the company's critical metals facility in South Korea's Ochang Foreign Investment Zone. Located 115 kilometres south of Seoul, the plant opened in May 2022 and is Australian Strategic's flagship metallisation plant.

According to Australian Strategic, it is the only ASX-listed company capable of producing rare earth metals and alloys commercially. The plant is one of the few facilities outside of China capable of producing the high-tech metals and alloys needed for clean energy technologies, advanced manufacturing, defence and aerospace.

Widespread Natural Rutile Observed Throughout the Central Rutile Tenement Package

DY6 Metals Ltd (ASX: DY6, “DY6” or “Company”) is pleased to announce the initial results from the reconnaissance exploration program at the Central Rutile Project, Cameroon. Desktop studies incorporating detailed geological mapping, geophysics, and known mineral occurrences, were used to define initial, high priority targets for ground-truthing. The reconnaissance programme, which consisted of auger sampling, road-cutting channel sampling, soil sampling and stream sediment sampling, was successful in identifying heavy mineral (HM) and natural rutile mineralisation across all five tenements that make up the Central Rutile project. Rutile nuggets, ranging in size from 1mm+ to 2cm+, were observed in alluvial and eluvial (residual) sources. Samples collected from the initial exploration programme are currently being prepped for dispatch to the Company’s laboratory for analysis in South Africa, with results expected in August 2025.

Hyundai Builds Rare Earths Stockpile to Offset Supply Risks

As global automakers brace for fallout from China’s tightening grip on rare earths exports, Hyundai Motor (KRX:005380,OTC Pink:HYMTF) appears to have quietly positioned itself ahead of the curve.

According to Reuters, a source familiar with the matter said on a recent investor call that the auto giant has stockpiled enough rare earth materials to maintain uninterrupted electric and hybrid vehicle production for about a year. The strategic stockpile should buy Hyundai critical time as supply chains buckle under mounting geopolitical tension.

China’s April decision to restrict exports of seven rare earths — a move requiring producers to obtain government licenses — has sent shockwaves through the auto, aerospace and semiconductor industries, particularly in the west.
