Eclipse Metals (ASX:EPM) has commenced preliminary metallurgical test work on its Grønnedal Rare Earths Project in Greenland, with samples from historic drilling now in Perth.
The program focuses on assessing wet high-intensity magnetic separation properties, a key technique for separating magnetic from non-magnetic minerals in rare earth concentrates.
Seven composite samples, prepared from previously collected material, have been submitted to ALS Laboratories in Perth for analysis.
Core from the 2025 Greenland diamond drilling program has also been logged, sampled, and dispatched for laboratory testing, with results expected to inform further metallurgical studies.
Initial observations indicate rare earth mineralisation is commonly associated with iron-rich zones that respond strongly to magnetic separation, supporting staged WHIMS testing.
