The core exhibits classic ferro-carbonatite textures, breccia with syenite (a potassium-rich granitoid) clasts and a magnetite-rich matrix, all of which are consistent with observations made during previous trenching, sampling and historic drilling.
Samples have been shipped for analysis to Qaqortoq, about 130 kilometres southeast of Eclipse’s project, with assays expected in Q1 2026.
The company has now moved its drill rig to the Ivigtût cryolite mine, about 7km to the southeast, to probe the unusually-prolific zoned mineralisation associated with the historic cryolite open pit.
Ivigtût is one of the few places on Earth known to contain naturally-occurring cryolite, a sodium aluminium fluoride which was previously used as an important agent in aluminium extraction.
After a brief period of exploiting mineralised former waste rock from the mine, it was shuttered back in 1987.
Field evaluation and analytical tests on bulk samples have confirmed a complex assemblage of potentially economic minerals in the mine environs.
The minerals include fluorite, high purity quartz, galena (lead), sphalerite (zinc), siderite (iron carbonate) and cryo-lithionite, a sodium aluminium lithium fluoride that resembles cryolite chemically but also contains a high lithium component.
The observed mineral assemblage is confirmed by locally-anomalous silver, copper, lead, zinc, gallium and lithium.
Eclipse’s current diamond drilling at Ivigtût is designed to probe the impressive and possibly valuable mineral suite to determine its extent, distribution, zonation and geometry before embarking on future metallurgical recovery testwork and resource evaluation and modelling.
Grønnedal’s scale and Ivigtût’s polymetallic potential reinforce Eclipse’s multi-commodity foothold in Greenland’s critical minerals sector, which is now backed by its strategic ties with the US through its proposed NASDAQ dual listing and alignment with Greenland’s 2025–2029 resources strategy.
With Grønnedal’s potentially vast, vertically-extensive carbonatite system now drill-confirmed and Ivigtût’s polymetallic promise currently lurking beneath, Eclipse is fast-tracking two world-class critical mineral prospects under its single Greenland licence.
Further evaluation looks almost certain to position the company to deliver magnet rare earths and other important industrial metals for the growing global new energy transition.
