Eclipse Metals (ASX: EPM) has unveiled a major increase to the rare earths resource at the Grønnedal deposit within its wholly owned Ivigtût critical mineral project in south-west Greenland.

The deposit’s new inferred mineral resource estimate (MRE) sits at 89 million tonnes at a grade of 6,363 parts per million total rare earth oxides (TREO), containing 567,600t TREO using a 2,000ppm TREO cut-off.

This represents a more than seventyfold increase to the original MRE and significantly enhances Grønnedal’s scale, strategic value and resource potential.

Maiden resource

The new resource replaces the maiden inferred resource at Grønnedal of 1.18Mt grading 6,859ppm TREO at the same 2,000ppm TREO cut-off and based solely on shallow drilling and trenching.

With an average grade exceeding 6,000ppm (0.65%) TREO, the new estimate positions Grønnedal among the world’s highest-grade rare earth deposits.

The mineralisation remains open in all directions, reinforcing the project’s strong resource potential.

‘Transformational milestone’

Eclipse executive chairman Carl Popal described the increase as a “transformational milestone” for the company.

“Our work at Grønnedal includes data from six deep historical diamond drill holes, all of which ended in mineralisation which potentially extends well beyond the current resource limits,” he said.

“There is evidence to suggest we are only scratching the surface here… we believe Grønnedal has the scale and grade to become a cornerstone asset in global efforts to secure new and independent critical mineral supply chains.”

Historical data

The increase follows the incorporation of new data from six drill holes located in the southern portion of the resource footprint.

Results from a sampling program returned values above 2% and included high concentrations of key magnetic rare earths such as neodymium, praseodymium, dysprosium and terbium.

It also extended the inferred resource boundary to a depth of between 165 metres and 200 metres from surface.

Eclipse believes the updated resource estimate represents just 6% by volume of the estimated carbonatite rock mass at the Grønnedal Complex.

Future drilling

Mr Popal said there were indications of continuous mineralisation from surface to depths exceeding 500 metres and indicated that future work would include new drilling to expand the resource base and fully realise the deposit’s potential.

“Given the current geopolitical context and growing demand for clean energy technologies, we are fast-tracking plans for further drilling to delineate the broader potential of the Grønnedal carbonatite,” he said.

“As a small company entering a much larger strategic arena, we remain focused on delivering value to shareholders and progressing responsibly, with discipline and transparency.”
