European Lithium (ASX:EUR) has reported substantial rare earth mineralisation in initial assay results from its 2025 drilling campaign at the Fjord and Upper Fjord deposits within the Tanbreez Project in Greenland.
The company said the assays revealed total rare earth oxide plus yttrium grades of up to 0.47%, with heavy rare earth oxides accounting for roughly 26–27% of the total.
The findings are expected to bolster European Lithium’s plans to update its mineral resource estimate and advance mine planning studies, according to executive chair Tony Sage.
"These results are expected to contribute additional mineralised tonnage to the existing Hill and Lower Fjord deposits and further support the scale and continuity of the Tanbreez Project," he said.
European Lithium's external resource and mining consultants are currently validating the data while progressing pre-development pit optimisation and resource studies.
The project’s multi-commodity potential also continues to attract attention, with consistent identification of gallium, hafnium, yttrium, and cerium oxides, alongside zirconium, niobium, and tantalum.
In a related development, Critical Metals Corp, in which European Lithium holds a 45% stake, has signed an agreement with Saudi industrial group Tariq Abdel Hadi Abdullah Al-Qahtani & Brothers to establish a 50/50 joint venture for a rare earth processing facility in Saudi Arabia.
The deal includes long-term offtake rights for 25% of Tanbreez's rare earth concentrate production, supporting secure supply for advanced manufacturing, energy transition, and defense sectors.
At the time of reporting, European Lithium's share price was $0.27.
