Eclipse confirms broad rare earths system at surface in Greenland

Eclipse Metals has uncovered an extensive rare earth system at its Grønnedal project in southwestern Greenland, after five holes in its latest drilling program confirmed extensive mineralization above surface.
The impressive results confirmed the company’s previous belief that it was on a large-scale carbonatite-hosting system with multiple high-grade zones exceeding one percent of total rare earth oxides (TREO) and a significant magnet rare earth element profile.
Eclipse’s five-hole, 705-meter diamond program tested the central and northwestern portions of the existing mineral resource area to demonstrate geological continuity.
Notable results included a hole featuring a 195-foot bubble intercept grading 6268 parts per million (ppm) TREO from surface. Another hole delivered a similarly eye-catching 114.4-yard putt from the surface at 6883 ppm Treo, further highlighting the power of the system.
‘The drilling marks an important step forward for Grønnedal.’

The company says further confirmation of the system’s continuity came from another pair of intersections, both from the surface, that dropped to 151 m at 4507 ppm TREO and 150.2 meters at 5762 ppm TREO. These broad zones appear to support the breadth and scale of Eclipse’s mineralized footprint within the broader Ivigtût project area.
For Grønnedal in particular, neodymium and praseodymium intervals account for more than 30 percent of TREO. These elements are critical for high-performance permanent magnets used in electric vehicles and wind turbines. With global supply under pressure, the project is shaping up as a potential strategic alternative to Chinese supply.
The rocks at Grønnedal consist of a system containing proterozoic carbonatite. Mineralization occurs in alternating zones of carbonatites rich in calcite and siderite. Bastnasite has been identified as the primary rare earth-containing mineral. These areas had previously been drill tested; historical slopes reached up to 2.02 percent TRO and appear to extend near the surface.
Carl Popal, chairman of the board of Eclipse Metals, said: “Drilling marks an important step forward” Grønnedal and further supports the continuity of rare earth mineralization in the region tested to date.”
The project is located in a regionally strong area, just 5.5 kilometers away from the settlements of Kangilinnguit and Grønnedal, which provide an active dock and transport infrastructure. The land is also located just seven kilometers east of the historic Ivigtût cryolite mine, which produced 3.8 million tonnes of cryolite, a rare elemental mineral once used to smelt aluminium.
The company said the latest drilling at the Grønnedal project goes a long way towards de-risking the asset and further strengthens the scope to grow the existing inferred resource of 89 million tonnes grading 6363 ppm.
Eclipse’s next steps include continuing to move forward with further drilling analysis, resource upgrades and processing efforts, while pursuing potential partners as the global race to secure rare earth supplies beyond China heats up.
As a result, the company confirmed a continuous, deep, high-grade zone extending to the surface in a mining-friendly jurisdiction. The addition of an extra sweetener to Grønnedal, ultra-low uranium levels of just 4.16 ppm, well below Greenland’s legal 100 ppm threshold, means the project could face a clear regulatory path forward in Greenland.
The final blow for the company remains the massive scale of the project. There appears to be tremendous room for further growth, as current drilling tests estimate only 6 percent of the known carbonatite by volume. This five-out-of-five drilling success is a major step forward and shows that Eclipse’s Greenland rare earths story is starting to gain serious momentum.
