Eclipse Metals Ltd (ASX: EPM) is pleased to report highly encouraging analytical results from 23 selected core samples from six historic diamond drill holes that were completed at the Company’s flagship Ivigtût multi-commodity project in southwest Greenland.
The results confirm the presence of high-grade rare earth element (REE) mineralisation at the Grønnedal Prospect, which is located within the Ivigtût Project Area.
The analyses, conducted by SGS Laboratories in Canada, demonstrate the occurrence of significant Total Rare Earth Oxide (TREO) values. A sample from drillhole R between 25.5 and
25.8m returned 20,092ppm (2.01%) TREO thus reinforcing the project's potential as a strategically located and globally significant source of magnetic and critical REEs essential for decarbonisation and advanced technologies.
Significant Analytical Results include:
- Drillhole R (25.5–25.8m) returned 20,092ppm (2.01%)TREO with 4,677ppm Nd₂O₃, 1,143ppm Pr₂O₃, 246ppm Dy₂O₃, 855ppm Y₂O₃ and 58ppm Tb₂O₃;
- Drillhole S (14.7–15.2m) returned 17,595ppm TREO including 4,269ppm Nd₂O₃, 484ppm Y₂O₃ and 371ppm Gd₂O₃
Director of Eclipse Metals, Mr Carl Poppal, stated:
“These latest analytical results are outstanding. They exceed our expectations and confirm the scale and quality of REE mineralisation present at depth in the Grønnedal prospect. With TREO grades over 2%, including significant Nd, Pr, Dy and Tb concentrations, the magnetic rare earth potential is truly world-class. Importantly, these findings allow us to calibrate the HyperXRF system, enabling rapid assessment across the broader project area and helping fast-track our pathway to an expanded MRE and feasibility development.”
Introduction
The Grønnedal carbonatite-hosted mineral resource is located within the Grønnedal Igneous Complex (Figure 1). The initial mineral resource estimate (MRE) (Table 1) is based on limited shallow drill testing of a small portion of the larger carbonatite complex.
Table 1:Grønnedal Classified Mineral Resource (LREO: Light Rare Earth Oxides, HREO: Heavy Rare Earth Oxides, MREO: Magnet Rare Earth Oxides)
The MRE is underpinned by analytical data derived from both exploration trenching and shallow drilling programs (refer to ASX announcement 25 July and 8th August 2023). Thus, the vertical extents of the MRE are limited to an average depth of only 12m.
In 1950, Kryolitselskabet Øresund A/S, Cryolite Company drilled six diamond holes in the vicinity of the Grønnedal resource to test for a potential iron ore deposit (Figure 1). This drilling extends to depths of up to 200m.
During 2024, the Greenland Government granted Eclipse permission to conduct non-destructive analyses of the government-archived core from these drillholes using the Minalyze XRF TruScan technology developed by Veracio in Gothenburg, Sweden. These data, which are summarised in Table 2, suggest that anomalous rare earth mineralisation, as defined by six key indicator elements, extends to depths of approximately 200m (refer to ASX announcement January 2025).

To verify the TruScan data, conventional laboratory analyses were required. In late 2024 Eclipse were allowed to extract small specimens from selected core intervals, using sampling protocols approved by the Greenland Government, from 23 intervals representing key lithologies for analytical test work. Sample treatment was carried out by SGS Lakefield, Canada using a sodium peroxide (Na₂O₂) digestion followed by ICP-MS (Inductively Coupled Plasma Mass Spectrometry).

Thick zones of HM mineralisation observed across Douala HM Project
HIGHLIGHTS
- The Company’s reconnaissance auger and channel sampling programme has been completed at the Douala Basin HMS Project
- Reconnaissance sampling undertaken across the 6 Douala Basin tenements has identified thick zones of high estimated concentrations of heavy minerals (HM) as well as natural rutile
- Work at the Douala Basin Project followed up on historical HM occurrences identified by previous Eramet drilling, as well as priority areas identified through the Company’s internal reviews
- Samples collected from the reconnaissance program are due to be submitted for laboratory analysis in the coming weeks, with results expected in the September quarter
- At Douala Basin, exploration will transition to a detailed campaign of auger drilling
Samples collected from this initial exploration programme are currently being prepped for dispatch to the Company’s laboratory for analysis in South Africa, with results expected in the September quarter.
Technical Consultant, Cliff Fitzhenry, commented: “While the Company’s primary focus is on the Central Rutile Project, where we have recently reported the presence of wide-spread residual natural rutile mineralisation, we believe that the Douala Basin HMS project has significant potential. The reconnaissance programme has over the last few weeks demonstrated the potential of the area, with the identification of high concentrations of visible heavy mineral sands across the project tenements through a mixture of auger, channel, and soil sampling work. Pleasingly, we have also observed natural rutile grains at Douala Basin.
We look forward to the assay results of the reconnaissance programme in the coming months.”
Reconnaissance exploration at the Douala Basin HMS Project
As announced on 5 June 2025, the Company commenced reconnaissance auger and grab sampling programmes at the Central Rutile and Douala Basin HMS projects, Cameroon. At the Douala Basin project, the Company has completed 12 hand auger drill holes (refer Figure 1), collecting 53 samples in the process, as well as collected 38 channel samples from 11 surfaces for analysis (refer Tables 1 & 2).

Cautionary Statement:
The Company cautions that, with respect to any visual mineralisation indicators, visual observations and estimates of mineral abundance are uncertain in nature and should not be taken as a substitute or proxy for appropriate laboratory analysis. Visual estimates also potentially provide no information regarding impurities or deleterious physical properties relevant to valuations. Assay results from the drilling and sampling programmes will be required to understand the grade and extent of mineralisation. Initial assay results are expected in August 2025.
