What is the Tanbreez Project and Where is it Located?
The Tanbreez Project stands as one of the most promising rare earth element (REE) deposits globally. Strategically positioned in southern Greenland, approximately 40 kilometres from the town of Narsaq, it forms an integral part of the european lithium and tanbreez project in greenland. Furthermore, its location in the Ilimaussaq Complex, a unique alkaline intrusion dating back 1.16 billion years, underscores its geological importance.
Greenland’s stable political environment and rich mineral endowment have enhanced international attention for this deposit. In addition, the region’s vast untapped resources have made it an attractive alternative to more volatile REE-producing regions. Notably, the deposit is attracting governments and investors worldwide.
Australian geologist Greg Barnes has dedicated over 22 years and invested $45 million of his own funds to define this resource. His commitment clearly highlights the significance of the project. Moreover, such dedication reinforces global confidence in the project's future, particularly as part of initiatives like Australian Government’s $400 Million Boost to Iluka’s Rare Earth Refinery.
What Makes the Tanbreez Project Significant for Rare Earth Elements?
The maiden resource estimate of Tanbreez reveals an impressive 45 million tonnes of ore with a Total Rare Earth Oxide (TREO) grade of 0.38%. Although the grade may appear modest, it is the unique composition of the deposit that makes it stand out. Consequently, the deposit offers a competitive advantage in the rare earth sector.
A striking 27% of its rare earth content comprises Heavy Rare Earth Oxides (HREO). In addition, elements such as dysprosium, terbium, and yttrium feature in commercially significant concentrations. These heavy rare earths are critical for manufacturing advanced electronics, permanent magnets, and defence technologies, thereby underscoring the deposit’s high economic potential.
Furthermore, the deposit benefits from a remarkably low uranium content of less than 50 ppm. This figure is considerably lower compared to other deposits where radioactive levels may exceed 400 ppm. Consequently, the processing methods can be simpler and more environmentally friendly. This advantage will likely attract further technical and financial interest.
What Do the Recent Drilling Results Reveal About the Deposit?
Recent deep diamond drilling campaigns have confirmed that the deposit’s mineralisation extends far beyond initial expectations. For instance, drill hole DX-01 reached 338 metres and reported 0.42% TREO, including an impressive 24.45% Heavy Rare Earth Element component. Additionally, drill hole D7-14 at 243 metres intercepted 0.44% TREO with 28% HREE.
These consistent results reinforce the economic potential of the resource, as the mineralisation remains continuous at depth. In addition, the findings open up the possibility of further resource expansion. For a detailed interpretation of these outcomes, consider a beginner’s guide to understanding mining drilling results. Furthermore, recent high-grade rare earth findings confirm the potential for an enhanced resource.
What Other Valuable Minerals Are Present in the Tanbreez Deposit?
In addition to rare earth elements, the Tanbreez deposit contains other valuable critical minerals. This polymetallic nature provides multiple revenue streams for a single mining operation. The additional minerals include tantalum, niobium, zirconium, hafnium, and gallium.
The main highlights are:
• Tantalum pentoxide: 73-83 ppm, used in electronic capacitors and medical implants.
• Niobium pentoxide: 1,174-1,496 ppm, essential for high-strength steel and superconducting applications.
• Zirconium (with hafnium): Averaging 2-3%, used in nuclear power and ceramics.
Furthermore, gallium has significant applications in semiconductor technology. In addition, this aggregation of minerals represents further economic and processing benefits. It also illustrates mining’s crucial and paradoxical role in the clean energy transition, ensuring efficient byproduct recovery.
How is European Lithium Expanding the Project?
European Lithium is undertaking a strategic three-phase drilling programme to expand and better define the resource. Specifically, the focus is on the Hill Zone and Fjord Deposit areas, where previous exploration identified the highest heavy rare earth concentrations. This approach forms a critical component of the european lithium and tanbreez project in greenland.
The expansion involves systematic step-out drilling to depths of 250–300 metres. In addition, an infill drilling strategy along the 1,037-metre strike length will improve the confidence level in resource categorisation. Consequently, this drill programme, which targets both resource expansion and infill, is scheduled for 2025. Furthermore, the initiative reflects European Lithium’s commitment to advancing the project.
What is the Ownership Structure of the Tanbreez Project?
European Lithium currently holds a 7.5% direct stake in the Tanbreez Project. In addition, the majority partner Critical Metals Corp controls 42% of the asset, with options to increase its interest up to 92.5% based on milestones. This staggered ownership model supports progressive capital investment and effective risk management.
This strategic partnership brings together European Lithium’s market presence and Critical Metals’ technical expertise in mineral development. Furthermore, the structure underpins investor confidence with phased capital commitments. In addition, initiatives like Australia’s revolutionary critical minerals tax incentives underscore the broader financial dynamics influencing similar projects.
Why Are Western Governments Interested in the Tanbreez Project?
Western governments have shown significant interest in the project due to its potential role in strengthening rare earth supply chains. For instance, global reliance on Chinese rare earth supplies, which account for about 85% of production, poses strategic risks. In addition, countries are eager to secure alternative sources of critical minerals.
Moreover, the deposit’s secure location in Greenland makes it politically attractive compared to volatile regions. In addition, the project directly supports initiatives that promote secure supply chains. Consequently, it is considered a major asset in the critical minerals race amid global resource nationalism.
What is the Economic Potential of the Tanbreez Project?
European Lithium is currently conducting a Preliminary Economic Assessment (PEA) for the project, with results expected by late 2025. Early modelling indicates that the deposit could support a long-life operation producing significant volumes of heavy rare earths. In addition, the estimated contained rare earth value potentially exceeds $10 billion.
Key economic advantages include lower processing costs due to the low uranium content and easy acid solubility of the primary minerals. Industry forecasts also suggest a potential 4-5 fold increase in dysprosium demand by 2035. Furthermore, the project’s robust fundamentals help solidify its status as a key asset within the european lithium and tanbreez project in greenland.

How Does Tanbreez Compare to Other Rare Earth Projects?
Tanbreez distinguishes itself from other deposits through several key attributes. The deposit’s heavy rare earth content of 27% is significantly higher than that in most conventional deposits. Consequently, it aligns with the most sought-after rare earth deposits worldwide.
In addition, the deposit’s exceptionally low radioactive element content minimises regulatory and environmental challenges. Moreover, its strategic proximity to deep-water fjords enables efficient shipping access to European and North American markets. These factors combine to create a competitive advantage in an ever-changing global resource market.
The deposit also benefits from a favourable processing profile compared to other rare earth projects. In addition, projects that require high-temperature caustic processes are less appealing relative to Tanbreez’s mild acid extraction methods. Overall, the potential of the european lithium and tanbreez project in greenland is further enhanced by these technical and economic advantages.
FAQs About Rare Earth Elements and the Tanbreez Project
