European Resources Doubles Korsnäs Rare Earth Resource to 15.4Mt at 1.00% TREO

Korsnäs Resource Surges Past 15 Million Tonnes

European Resources Limited (ASX:ERE) has significantly expanded its rare earth footprint at the Korsnäs project in Finland, boosting the Inferred Mineral Resource Estimate (MRE) to 15.4 million tonnes grading 1.00% total rare earth oxides (TREO) at a 0.5% cut-off. This figure more than doubles the maiden December 2024 estimate of 7.1Mt at 1.09% TREO and builds on last year’s 13.5Mt upgrade, reflecting ongoing drilling success and refined geological modelling. The resource remains classified as Inferred, pending completion of metallurgical studies needed to underpin higher confidence classifications. The latest update integrates data from six new diamond drill holes (KR-311 to KR-316) alongside re-assayed historical core, improving continuity and down-dip extensions across 42 mineralised domains. This milestone was previously reported in April but is now reinforced by the latest quarterly activities.

Drilling confirmed broad zones of rare earth element mineralisation, particularly enriched in neodymium and praseodymium (NdPr), key magnets metals. Noteworthy intercepts include 31.5m at 4,902 ppm TREO from 98.5m in hole KR-316, including higher-grade intervals up to 14,003 ppm TREO with NdPr enrichment approaching 30%. This hole validated a southern exploration target identified by coincident gravity and Horizontal Vertical Spectral Ratio (HVSR) passive seismic anomalies, highlighting the value of these geophysical tools in uncovering new mineralised zones beneath cover. The program also tested near-mine continuity and extensions west of the mine, confirming multiple mineralised structures around the historic Korsnäs mine site.

Metallurgical Advances Clarify Processing Pathways

Parallel metallurgical test work advanced with encouraging results from several fronts. GTK-Mintec’s beneficiation tests on drill core samples using high-gradient magnetic separation (HGMS) and flotation demonstrated significant TREO grade upgrades; up to 129% on apatite-monazite dominant material with recoveries around 74%. ANSTO Minerals progressed downstream hydrometallurgical testing on historical lanthanide concentrate stockpiles, investigating acid bake and water leach conditions to optimise impurity removal. Additionally, sulphide flotation on tailings showed promise in separating lead and sulphides, albeit with some rare earth losses. These efforts, conducted under the EU-funded REMHub program, are shaping a more realistic processing flowsheet combining HGMS and flotation for fresh hard-rock material. The company plans to composite fresh drill core for mini-pilot scale test work to refine beneficiation and hydrometallurgical steps further.

These metallurgical developments are timely given the resource upgrade and the company’s ambition to build scale and de-risk processing. The integration of geophysics, drilling, and metallurgy is steadily improving geological confidence and technical understanding of Korsnäs, positioning it as a potential future supplier aligned with the European Union’s Critical Raw Materials strategy.

Capital Raise to Fund Next Phase

To underpin ongoing exploration and metallurgical programs, European Resources withdrew an earlier rights issue offer and relaunched a 3-for-7 renounceable rights issue priced at $0.015 per share, including a 1-for-1 attaching option exercisable at $0.04, aiming to raise approximately $3.4 million. The offer is partially underwritten by Mahe Capital Pty Ltd for $1.5 million, providing a financial buffer amid current market volatility. Proceeds will primarily fund further metallurgical test work and extensional drilling designed to enhance the resource base and support project valuation. The company reported exploration and evaluation expenditure of $840,683 during the quarter, with no mining production or development costs incurred.

Cash reserves stood at $149,000 at quarter end, reflecting the significant investment in drilling and test work. The capital raise is critical to maintain momentum, especially as the company awaits final reimbursements from the REMHub program and progresses feasibility-related studies. The rights issue terms and underwriting arrangement aim to balance shareholder participation with financial prudence.

Exploration and Development Outlook

Beyond Korsnäs, the company’s Jokikangas HFSE–HREE project in Finland remains under review, with up to 81 historical drill holes slated for assessment. No field activities occurred at Slovakian licences during the quarter, some of which are undergoing re-granting processes. European Resources plans to extend HVSR geophysical surveys and follow-up drilling at Korsnäs to test additional covered targets, aiming to further delineate resource upside. The integration of geophysical targeting with drilling and beneficiation test work will continue to shape the project’s development pathway.

Strong local community support, as evidenced by site visits and engagement, adds a positive social dimension to project advancement. The company’s strategy includes rehabilitating infrastructure from the historic Korsnäs mine, potentially reducing capital intensity for future development. However, the resource remains fully Inferred, with metallurgical and feasibility data still evolving, underscoring the early stage of the project’s commercialisation journey.

European Resources’ recent progress builds on its earlier resource doubling and metallurgical breakthroughs, including strong Korsnäs beneficiation results and the $3.4 million renounceable rights issue, both instrumental in sustaining momentum. The company’s focus on NdPr-enriched rare earths aligns with growing demand for permanent magnets critical to clean energy technologies and electric vehicles.
