European Lithium Ltd (ASX: EUR, FRA:PF8, OTC: EULIF) (European Lithium or the Company) is pleased to publish for the first time, historical deep diamond drill holes DDH 7-14 drilled in 2007, and DX-01 drilled in 2010 from the Tanbreez Project in Greenland.

Highlights - Diamond Drill Hole Historical Results

Drill hole DX-01 was successfully drilled vertically to 338m from surface and intersected high - grade rare earths and oxides averaging:

• 4209.22ppm (0.42% TREO) (“including averaged heavy rare HREO of 24.45%”),
• 2.45% ZrO₂ “zircon oxide” cut off at 0.5%,
• 73ppm Ta₂O₅ “tantalum pentoxide”,
• 1174.06ppm Nb₂O₅ “niobium pentoxide”,
• 266.45ppm HfO₂ “hafnium oxide”,
• 103.03ppm Ga₂O₃ “gallium oxide”,
• Mineralisation average from surface to 338m downhole.

Diamond Drill hole Drilled DX-01 was drilled to 338m depth within the Hill Zone 22MT @ 0.38% REE Maiden Mineral Resource (13 March 2025 ASX Announcement 45MT @ 0.38% TREO).

Drill hole D7-14 was successfully angle drilled at 15⁰ east to 243m from surface and intersected high-grade rare earths mineralisation averaging:

• 4437.54ppm (0.44% TREO) (“including averaged heavy rare HREO of 28%”),
• 1.78% ZrO₂ “zircon oxide” cut off at 0.5%,
• 83ppm Ta₂O₅ “tantalum pentoxide”,
• 1496ppm Nb₂O₅ “niobium pentoxide”,
• 351ppm HfO₂ “hafnium oxide”,
• Ga₂O₃ “gallium oxide” was not assayed,
• Mineralisation average from surface to 243m downhole.

European Lithium currently holds a 7.5% direct interest in the Tanbreez Project. By way of background, European Lithium first acquired a 5% interest in Tanbreez Mining Greenland A/S (Tanbreez) on 3 October 2022 and acquired a further 2.5% interest in Tanbreez on 6 February 2023 from the privately owned Australian company Rimbal Pty Ltd (Rimbal). At this time, the investment of 7.5% in Tanbreez was not considered material to the Company and as such the historical drill hole data and results was not disclosed at the time of acquiring an interest in Tanbreez. In June 2024, Critical Metals Corp. (NASDAQ: CRML) entered into the Heads of Agreement with Rimbal to acquire up to 92.5% in Tanbreez and have completed the initial investment and stage 1 interest to hold a 42.0% interest in Tanbreez. As of the date of this announcement, European Lithium and CMC hold a combined interest of 49.5% in Tanbreez. European Lithium is CMC’s largest shareholder and as such now considers the Tanbreez Project to be material and as a result is announcing historical data and information in this announcement.

The Company recently announced its Maiden Mineral Resource Estimate (MRE) for the Tanbreez Project of 45MT containing 0.38% TREO including 27% contained HREO plus rare metal oxides (see ASX Announcement 13 March 2025).

The Company is awaiting assay results from the September-November 2024 confirmation drilling program comprised of sixteen holes, with the first hole A1-24 reported January 2025, and will publish the remaining 15 diamond drill hole assay results when they become available.

The drilling results from A1-24 drilled 2024 (ASX Announcement 20 January 2025) confirmed a significant 40m deep intersection from outcropping surface mineralisation of high-grade rare-earth oxide averaging:

• 4,722.51ppm (0.47%TREO) (including 26.96% averaged heavy rare earth (” HREO”),
• 1.82% ZrO₂ “zircon oxide”,
• 130.92ppm Ta₂O “tantalum pentoxide”,
• 1852.22ppm Nb₂O₅ “niobium pentoxide”,
• 393.68ppm HfO₂ “hafnium oxide”,
• 101.67ppm Ga₂O₃ “gallium oxide”.

The assay results from historical deep diamond drill holes DX-01 and D07-14 (that were drilled by Rimbal P/L in May 2007 and 2010) confirm similar average grades to drill hole A1-24

Commenting on the assay results, Tony Sage, Executive Chairman of the Company, said:

”It’s exciting to report on the outstanding assay results from historical deep drilling which may confirm high-grade, high tonnage potential that extends a lot deeper than was originally expected for the Tanbreez Project”

“After recently announcing the MRE of ~45MT of REE’S @ 0.38% and other rare earth metals, the highly experienced team we have recently assembled, is moving quickly to measure the true potential of the Tanbreez Project that is also gaining significant interest from Western Governments.

“The team is now working through more of the historical data (which contains over 400 holes and 3cc,000 samples) of which most have never been made public. Some of this data is over 22 years old, so by using modern technology to decipher the $45 million of expenditure spent by Greg Barnes, it will add significant value to Tanbreez Project’s long term success”
