Eclipse Metals (ASX: EPM) — Grønnedal Rare Earth Resource Doubles to 208Mt at 0.72% TREO in Southwest Greenland
On 29 April 2026, Eclipse Metals Limited (ASX: EPM) announced a major update to the Mineral Resource Estimate (MRE) for its Grønnedal Rare Earth Element (REE) Project in southwest Greenland. The total MRE has increased to 208Mt at 0.72% TREO using a 2,000ppm TREO cut-off — a 234% increase in tonnage and a 12% increase in grade compared to the previous 89Mt Inferred Resource reported in 2025. The updated resource comprises 6Mt at 0.71% TREO (Indicated) and 202Mt at 0.72% TREO (Inferred), containing approximately 1.5Mt of total rare earth oxides including approximately 456,000 tonnes of Pr₂O₃ + Nd₂O₃ (praseodymium and neodymium oxides), representing approximately 31% of TREO — the key magnet rare earth elements used in permanent magnets for electric vehicles, wind turbines, and defence applications. The establishment of an initial Indicated Resource of 6Mt is a new milestone, providing a higher-confidence component to support feasibility-level studies. Additional drilling is planned for the 2026 Greenland field season, and feasibility work is now underway.

Grønnedal REE Deposit — Geology, Scale and Resource Extent
The Grønnedal deposit is a carbonatite-hosted rare earth element system forming part of the Proterozoic Grønnedal-Ika Complex in southwest Greenland. The complex comprises multiple carbonatite phases hosted within a broader alkaline intrusive sequence, intruded by dolerite and phonolite dykes which have been modelled as waste domains and excluded from the MRE.
The overall carbonatite complex measures approximately 5 km east–west by 1.2 km north–south. The current MRE footprint covers a significantly smaller area — approximately 725m by 490m projected to around 290m vertical depth — representing a relatively small portion of the total complex. Magnetic inversion modelling indicates the carbonatite body extends to depths exceeding 900m with a near-vertical, pipe-like geometry.
Rock-chip geochemistry has confirmed high-grade REE mineralisation up to approximately 1.6 km beyond the current resource limits. However, Inferred Resource wireframes have been conservatively limited to no more than 150m from the outermost drill or surface sample data points.
Mineralisation remains open along strike and at depth. Several drill holes terminate in high-grade REE zones, and trench sampling has returned strong REE grades along the northern and western limits of the sampling grid.

Table: Grønnedal MRE at 2,000ppm TREO Cut-Off
| Classification | Tonnage (Mt) | TREO Grade (ppm) | Contained TREO (kt) | MREO (kt) | Pr₂O₃+Nd₂O₃ (ppm) | Pr/Nd % of TREO |
|---|---|---|---|---|---|---|
| Indicated | 6 | 7,139 | 40 | 14 | 2,307 | 33% |
| Inferred | 202 | 7,242 | 1,465 | 464 | 2,191 | 30% |
| Total | 208 | 7,239 | 1,505 | 477 | 2,194 | 31% |
The resource also contains strontium oxide (SrO) at an average grade of 1.43%, for approximately 2,968kt contained SrO across the 208Mt.
The MRE was prepared using Leapfrog Edge (v2025.3.1) with Ordinary Kriging interpolation applied to validated drillhole assay data composited to 1m downhole intervals. A two-pass kriging approach was used with initial search parameters of 70m × 30m × 15m and expanded ranges of 250m in the second pass. Bulk density was estimated at 3.21 g/cm³ based on 515 core samples using the water immersion method. Indicated classification was applied to blocks within 25m of supported drillhole information. No top cuts were applied. Uranium occurs at very low levels (below 6ppm).
Drilling Data Supporting the MRE
The MRE is based on six HQ-sized diamond drill holes and 33 percussion drill holes completed by Eclipse Metals, supplemented by six historic NQ-sized diamond drill holes. All holes intersected REE mineralisation. Core recovery from the 2025 diamond drilling program averaged 98.2%. Quarter HQ core was used as the primary sample, with half HQ core samples collected at a 1-in-20 ratio for duplicate QAQC purposes. Samples were analysed by ALS Laboratories using the ME-MS61-REE and ME-MS81 methods.
In addition, 25 analyses conducted on specimens from historic diamond core (drilled approximately 1940, 1948, and 1985) were incorporated to support the Inferred Resource definition.
Feasibility Work and Next Drilling Program
Eclipse has commenced feasibility-related work including resource modelling and mine planning, metallurgical testwork and processing flowsheet development, environmental and social baseline studies, infrastructure and logistics assessments, permitting and stakeholder engagement, and development sequencing.
Additional drilling is planned for the upcoming 2026 Greenland field season, targeting increased Indicated classification, improved geological confidence within priority development areas, testing of extensions to known mineralisation, and support for feasibility-level mine planning.
No dedicated metallurgical recovery testwork has yet been carried out on Grønnedal samples. The company references analogues from similar carbonatite-hosted REE systems (Bayan Obo, Mountain Pass) and considers it reasonable to assume the mineralisation may respond to conventional beneficiation and hydrometallurgical processing. No open-pit optimisation or mine-planning studies have been completed.
Market Context
EPM closed at $0.020 on the announcement day, up +33.3% from a previous close of $0.015, with an intraday high of $0.026. The 52-week range spans $0.004 to $0.039. The announcement comes amid heightened Western government focus on securing critical mineral supply chains independent of Chinese dominance in rare earth production and processing. Greenland has attracted increased attention as a jurisdiction aligned with European and North American critical minerals priorities.
Risks & Considerations
Predominantly Inferred Resource: Of the 208Mt total resource, 202Mt (97%) is classified as Inferred. Inferred Resources carry a lower level of geological confidence, and there is no certainty that further drilling will upgrade this material to higher-confidence categories.
No metallurgical testwork: No dedicated metallurgical recovery testwork has been conducted on Grønnedal samples. The assumption of processing amenability is based on analogues from other carbonatite-hosted REE deposits, not project-specific data. Feasibility outcomes are uncertain until metallurgical parameters are established.
No economic studies: No open-pit optimisation, mine planning, or economic studies have been completed. The 2,000ppm TREO cut-off is based on assumptions about anticipated metallurgical recoveries and indicative long-term REE pricing, not on demonstrated project economics.
Competent Person is a company director: The Competent Person for the MRE, Alfred Gillman, is a Non-Executive Director of Eclipse Metals. While this is disclosed and permitted under JORC guidelines, it represents a potential conflict of interest.
Greenland operational challenges: Greenland is a remote, Arctic jurisdiction with a limited operating season, significant logistical requirements, and limited local mining infrastructure. These factors may increase costs and extend development timelines compared to established mining jurisdictions.
Funding risk: EPM is a micro-cap explorer. The announcement does not disclose the company's current cash position or funding plans for the upcoming drilling program and feasibility work. Further capital raisings may be required.
No audits of MRE: No independent audits or reviews of the Mineral Resource Estimate have been conducted.
Grade context: At 0.72% TREO, Grønnedal's grade is below that of several producing or advanced rare earth deposits (Mt Weld at 4.12% TREO, Araxá at 4.06% TREO, Mountain Pass at ~6% TREO). The project's economic viability will depend on factors including scale, strip ratio, metallurgical recovery, and the proportion of high-value magnet rare earths.
