Tanbreez drilling delivers REE goods for European Lithium with some extras

• Drilling at the Tanbreez project in Greenland from the previous year hits 0.4-0.42% TREO with high ratios of valuable heavy REEs
• All holes confirm continuity of grade and mineralogy across multiple sections of the Fjord deposit
• Results are consistent with historical data and more drilling is underway

Special Report: European Lithium has unveiled new assays from 2024 diamond drilling at the Fjord deposit within its Tanbreez project in Greenland that demonstrate consistent, high-grade rare earths mineralisation.

All reported holes, intersecting mineralisation at approximately true thicknesses, returned grades of between 0.4% and 0.42% total rare earths oxides.

Notably, the intersected mineralisation contains a high proportion of heavy rare earth oxides – an average of 26% of the TREO content – that highlight the deposit’s potential strategic value.

Adding interest for European Lithium (ASX:EUR), significant zirconium oxide of 1.57-1.58% was noted across all holes along with gallium oxide assays of 93-99ppm providing potential additional economic credits.

The drilling confirms continuity of grade and mineralogy across multiple sections of Fjord that is consistent with historical data and mineralisation remains open at depth in all reported holes.

All holes, part of the ongoing 2024-25 Fjord resource upgrade program, were collared within the current Fjord resource of 45Mt grading 0.38% TREO.

“These additional 2024 diamond drill hole results indicate the consistent grades of rare earth and gallium, with a high proportion of critical heavy rare earths,” executive chairman Tony Sage said.

“Our rare earth grades position Tanbreez as a strategically important asset for Western supply chains.

“With China’s control over the rare earth market, securing sources of these critical minerals has become paramount for US defence capabilities and national security.”

He added that the progress made with the Fjord resource upgrade extension program – with 1316m of diamond drilling completed in 2024 and more than 1850m completed to date in 2025 – significantly strengthened the company’s ability to build its resource base.

Fjord drilling

The Fjord drilling consisted of confirmatory and step-out holes to validate historical drilling data, refine the geological model for resource estimation, and providing material for metallurgical and environmental test work.

EUR notes that Fjord represents a significant portion of the overall Tanbreez rare earths inventory given its continuity of mineralisation over several kilometres.

Ongoing drilling is expected to further delineate these resources, with pending assays from additional holes likely to extend the known mineralised envelope and refine the grade distribution.

Additionally, previous drill holes that were not assayed for gallium, tantalum and niobium in 2013 will be assayed from existing pulps submitted to ALS Metallurgical in Perth for analysis in the coming months.

The company has a 7.5% stake in Tanbreez and owns ~68% of Critical Metals Corp, which owns 42% of Tanbreez and has the right to earn up to 92.5%.
