European Lithium Ltd Deep Drilling Reveals Significant Results

Deep Drilling Uncovers Extensive Mineralization

European Lithium Ltd (ASX: EUR) has announced exceptional deep drilling results from its Tanbreez Rare Earth Project in Greenland, revealing consistent high-grade rare earth elements (REE) mineralization at significant depths. The newly released results substantially expand the project's potential resource base, both laterally and vertically.

The deep drilling results from European Lithium Ltd demonstrate the project's impressive depth potential with consistent high-grade rare earth mineralization extending to depths of 328m and 195m in historical diamond drill holes DDH 306-13 (drilled in 2013) and DX-02 (drilled in 2010) respectively.

Key highlights from the deep drilling program include:

• Drill Hole DX-02: Averaged 0.42% TREO (Total Rare Earth Oxides) from surface to 195m, including 24% heavy rare earth oxides (HREO)
• Drill Hole D306-13: Averaged 0.45% TREO from surface to 328m, including 27% HREO
• Consistent Results: Recent drilling (A1-24) showed similar grades with 0.47% TREO to 40m depth, including 27% HREO

The new results are particularly significant as they indicate the continuity of mineralization to depth across a substantial strike length of approximately 2,300m, with a width of approximately 370m.

Tony Sage, Executive Chairman, commented: "It's exciting to report more deep diamond drill hole results and outstanding assay results from historical deep drilling that may confirm higher tonnage potential that extends a lot deeper and wider than was originally expected for the Tanbreez Project."

Critical Metals Content Enhances Project Value

Beyond the rare earth content, the deep drilling results from European Lithium Ltd revealed significant concentrations of other critical metals that add substantial value to the project:

Gallium is particularly noteworthy as it has recently been designated a critical mineral, with the high-grade gallium rates showing consistent values across multiple drill holes. The presence of these additional critical metals enhances the economic potential of the Tanbreez Project beyond its rare earth content.

Low Uranium and Thorium Content: A Key Advantage

The uranium and thorium assays from the deep drilling results averaged just 18.67 ppm and 55.3 ppm respectively – levels well below 80ppm. This represents a significant competitive advantage over many rare earth deposits worldwide, which often contain problematic radioactive elements requiring costly processing and waste management.

This low radioactive content could translate to:

• Simplified regulatory approvals
• Lower environmental impact
• Reduced processing costs
• Fewer waste management challenges

Understanding Rare Earth Mineralogy

The Tanbreez Project's mineralization is hosted within Kakortokite, a rare layered igneous rock composed primarily of feldspar, eudialyte, and arfvedsonite. This unique geological formation contributes to the project's exceptional characteristics.

Unlike most rare earth deposits globally that contain radioactive elements, Kakortokite-hosted deposits typically have minimal uranium and thorium content, making extraction simpler and more environmentally friendly. The deep drilling results from European Lithium Ltd confirm this favourable characteristic.

The project's high percentage of heavy rare earth elements (26-28% of total REE) is especially valuable for several reasons:

1. HREEs command significantly higher prices than light rare earths
2. HREEs are critical for permanent magnets used in electric vehicles
3. HREEs are essential components in wind turbines and defence applications
4. Supply of HREEs is more constrained globally

Following this rare earth elements discovery, the industry has seen renewed interest in identifying stable sources of these critical materials.

Strategic Growth Potential

European Lithium's Tanbreez Project already boasts a JORC 2012 Maiden Mineral Resource of 45MT containing 0.38% TREO (with 27% HREOs). The deep drilling results suggest potential for substantial resource expansion both laterally and at depth.

The recently released scoping study demonstrated robust economics with:

• NPV of US$2.4-3.0 billion (at 10% and 8% discount rates)
• IRR of 162% before tax

These figures may improve further if the additional resource potential indicated by the deep drilling results is incorporated into future economic analyses.

European Lithium Ltd has applied for a Program of Works for the 2025 resource drilling program targeting expansion of the current resource, with drilling teams preparing for mobilization by mid-to-late June. The drilling program will prioritize:

1. The Fjord Deposit containing 23MT of the current MRE
2. The Hill Zone Deposit containing 22MT of the current MRE

The company, which holds 7.5% interest in the project directly and approximately 68% of Critical Metals Corp (which holds a 42% interest with the right to earn up to 92.5%), is positioning Tanbreez to become a major non-Chinese supplier of rare earth elements to Western supply chains.

In a related development, Vital Metals secured funding for their rare earths project, indicating the growing investor interest in this sector.

Why Investors Should Take Notice

The Tanbreez Project's combination of high grades, significant depths, valuable heavy rare earth content, and low radioactivity makes it one of the most promising rare earth developments globally. As Western nations increasingly seek secure supplies of critical minerals outside of China, which dominates global rare earth production, Tanbreez offers a strategically important alternative with potentially decades of production.

The deep drilling results from European Lithium Ltd confirm several key attributes that differentiate this project:

• Consistent Mineralization: Grades remain consistent from surface to significant depths
• Strategic Metals Mix: High percentage of valuable heavy rare earths plus critical metals like gallium
• Clean Processing: Low uranium and thorium content simplifies processing and regulatory approval
• Expansion Potential: Resource likely to grow substantially from current 45MT

With resource extension drilling planned, a proven metallurgical process, and strong project economics already demonstrated, European Lithium is well-positioned to advance Tanbreez toward becoming a globally significant rare earth producer at a time when demand for these critical elements is projected to grow substantially.

Similar to recent high-impact exploration projects in the energy sector, the deep drilling results highlight the significant resource potential at Tanbreez, providing European Lithium Ltd with a compelling opportunity to develop a world-class rare earth project in a stable jurisdiction.

Furthermore, the discovery of high-grade antimony at other mining operations shows the increasing value of critical minerals in today's market, strengthening the case for European Lithium's diverse mineral portfolio at Tanbreez.
