Highlights
- First drilling results reveal high-grade rare earth elements in Greenland.
- The find includes tantalum, niobium, and gallium concentrations.
- The mineralisation stretches 18km by 8km, hinting at extensive resources.
European Lithium Ltd (ASX:EUR) has made significant strides in its exploration efforts at the Tanbreez Project, situated in southern Greenland, by reporting promising results from its first drilling hole. The exploration collaboration with Critical Metals Corp (NASDAQ:CRML) has focused on extracting valuable data on rare earth elements (REE) and other critical minerals found in the region, which is emerging as a notable player in the global mining industry.
The early results from the drilling have reinforced the potential of the Tanbreez site as a high-grade, high-tonnage source of both light and heavy rare earth elements, along with notable amounts of tantalum, niobium, and gallium. European Lithium holds a 7.5% stake in the Tanbreez Project, which was initially highlighted by Critical Metals Corp in November and December 2024.
The September-October 2024 drilling campaign covered 16 diamond drill holes. These holes were strategically designed to confirm the presence of high-grade rare-earth and other valuable minerals beneath the surface. Laboratory assays from the very first drill hole have confirmed mineralisation that extends across a 40-metre-wide zone. This substantial width features elevated levels of rare-earth oxides (TREO), with particular strength in heavy rare-earth elements (HREO), where the concentration reached 26.96%.
In addition to rare earth elements, other critical materials such as zircon oxide (ZrO2) and tantalum pentoxide (Ta2O5) were also identified. Assay results show 130.92 ppm of tantalum pentoxide, along with 1,852.22 ppm of niobium pentoxide (Nb2O5), 393.68 ppm of hafnium oxide (HfO2), and 101.67 ppm of gallium oxide (Ga2O3). These findings present the region as a potentially high-value mining hub, underscoring the strategic importance of Tanbreez.
Geologically, the Tanbreez Project is hosted within eudialyte, with a concentration of minerals in the kakortokite rock layer that forms the foundation of the Ilimaussaq intrusive complex. This complex spans a vast area of around 18 kilometres by 8 kilometres, and mineralised zones extend deep underground, with significant exposures over a 5-kilometre by 2.5-kilometre stretch.
The team at European Lithium is excited by the results, with Executive Chairman Tony Sage emphasizing the high-quality mineralisation just 40 metres below the surface, showcasing the immense potential the Tanbreez Project holds for both the company and the broader critical minerals market.
As the results from the remaining 15 drill holes are awaited, these early assays have set the stage for further exploration, providing an optimistic outlook for the future of the Tanbreez Project.
