European Resources Advances Rare Earth Recovery and Resource Expansion at Korsnäs Project in Finland

Wet High Gradient Magnetic Separation Enhances Rare Earth Recovery at Korsnäs

Metallurgical testing during the June 2026 quarter has refined European Resources' processing strategy for Korsnäs ore. GTK-Mintec, a Finnish research institute, conducted pre-concentration tests on two representative ore samples from 2025. The first, allanite-dominant mineralisation, assayed at 1.35% TREO, while the second, apatite-monazite-dominant mineralisation, assayed at 0.24% TREO. Each ore type required tailored process optimization to maximize rare earth recovery and grade upgrade.

Wet high gradient magnetic separation was identified as the most effective pre-concentration method tested. For allanite-dominant ore ground to P80 passing 100 micrometres, this method achieved an 84% rare earth grade upgrade and 85% recovery at 0.5 Tesla. Increasing the magnetic field to 1.8 Tesla boosted grade upgrade to 160% but reduced recovery to 42%. The apatite-monazite ore showed a 129% grade upgrade with 74% recovery at 0.5 Tesla, and a 220% upgrade with 26% recovery at 1.8 Tesla. These results were obtained without de-sliming, indicating potential simplifications in processing.

ANSTO Hydrometallurgical Analysis Highlights Monazite-Apatite as Key Magnet Rare Earth Hosts

ANSTO Minerals completed initial hydrometallurgical tests on a historical Korsnäs lanthanide concentrate stockpile, enhancing understanding of downstream processing. The composite sample contained 2.3 wt% total rare earth element yttrium equivalent, including 0.7 wt% magnet rare earths. This material, derived from accumulated historical production, serves as a practical test material for process optimization without new grinding.

Mineralogical analysis via scanning electron microscopy and X-ray diffraction identified monazite as the dominant rare earth mineral, with significant apatite presence and minor allanite. Approximately 60% to 70% of total rare earths are hosted in monazite, with a notable portion in apatite. Only a small fraction of neodymium and praseodymium—the primary magnet rare earths—reside in allanite. This distribution suggests that magnet rare earth value is mainly associated with the monazite-apatite assemblage, influencing process route selection and economics. Preliminary leach tests showed calcite removal at pH 4, apatite dissolution beginning near pH 1, consistent with mineralogy.

Post-Quarter ANSTO Acid-Bake Testing Extracts 83% of Magnet Rare Earths

Following the quarter, ANSTO conducted acid-bake and water-leach tests on untreated historical Korsnäs concentrate, achieving high extraction rates of key magnet rare earths. Praseodymium extraction reached 88%, neodymium 83%, and combined magnet rare earth extraction was 83%. Total rare earth element yttrium equivalent extraction was 86%, confirming the concentrate as a viable feedstock for process development.

Heavy rare earth extraction was lower, with terbium at 49%, dysprosium at 43%, and yttrium at 43%. This aligns with the apatite-hosted rare earth component identified, indicating the need for optimized pre-leach treatments to unlock full rare earth recovery. ANSTO's next phase will focus on refining pre-leach conditions alongside acid-bake and water-leach steps, and developing impurity removal processes targeting aluminium, uranium, and thorium—key challenges for producing market-grade rare earth products.

April 2026 Mineral Resource Estimate Increased to 15.4 Million Tonnes at Korsnäs

In April 2026, European Resources updated the Inferred Mineral Resource at Korsnäs to 15.4 million tonnes at 1.00% total rare earth oxide. This reflects ongoing exploration and geological modelling conducted alongside metallurgical and geophysical programs during the quarter. The Inferred classification is based on geological evidence and assay data but requires further drilling to achieve higher confidence categories.

This resource update strengthens the foundation for process development and engineering studies by quantifying mineralisation available for potential extraction. Managing Director Jason Beckton emphasized that combined resource definition, metallurgical progress, and geophysical targeting establish a technical framework to evaluate Korsnäs as a future rare earth producer. The Exploration Target remains conceptual until confirmed by drilling.

Passive Seismic Survey Uncovers Six New Exploration Anomalies Near Historic Mine

Phase 2 passive seismic surveying using Horizontal-to-Vertical Spectral Ratio (HVSR) methodology identified six new anomalies south and east of the historic Korsnäs mine and current Mineral Resource area during the June 2026 quarter. This cost-effective geophysical technique detects subsurface density and elastic property variations without active sources, proving effective in locating mineralised structures.

Five of the six anomalies are newly identified targets, indicating untapped prospectivity within the project area. Managing Director Beckton stated these anomalies are priority targets for upcoming drilling aimed at converting them into Mineral Resources. The company plans to advance metallurgical optimization while simultaneously testing geophysical targets, pursuing a dual strategy to enhance resource scale and economic viability.

Exploration Target Update Provides Framework for Future Resource Expansion

In June 2026, European Resources significantly increased the Korsnäs Exploration Target, offering a conceptual basis for potential mineral resource growth. This estimate is informed by geological interpretation, geophysical data, and metallurgical knowledge but remains untested by drilling, thus not classified under the JORC Code.

The updated target incorporates Phase 2 passive seismic anomalies and supports the view that mineralisation extends beyond current resource boundaries. Managing Director Beckton highlighted that drilling is essential to validate and convert these targets into Mineral Resources, balancing upside potential with exploration risks.

Renounceable Rights Issue Raises A$2.57 Million to Support Project Advancement

During the quarter, European Resources completed a renounceable rights issue, raising A$2,571,045 through issuance of 171,402,980 shares and options priced at A$0.015 each. The fully subscribed capital raise demonstrates strong shareholder backing and will fund metallurgical optimization, geophysical surveys, and drilling of new targets. Post-raise, the company’s share count stands at 694.9 million, with a market capitalization near A$10.4 million at the issue price.

Funds will support the company’s strategic objectives of refining processing routes and expanding Mineral Resources through targeted exploration. The Korsnäs project remains at an early development stage, pending advancement toward production.

Korsnäs Project’s Strategic Role in European Rare Earth Supply Chain

Located in Finland and fully owned by European Resources Limited, the Korsnäs rare earth project holds strategic significance for Europe’s drive to diversify rare earth supply chains. Europe aims to reduce reliance on Asian producers by developing domestic sources for battery metals and permanent magnets critical to renewable energy and electric mobility.

Korsnäs encompasses the historic mine site and additional prospective land, benefiting from proximity to European markets, established infrastructure, and a skilled workforce. However, the project faces challenges including environmental permitting, workforce recruitment, and energy costs within a regulated European context. The company is addressing these through a phased development strategy focused on metallurgical optimization and resource delineation prior to engineering and construction.

Managing Director Jason Beckton Highlights Metallurgical and Exploration Milestones

Jason Beckton, Managing Director, noted significant progress in metallurgy, geophysics, and resource definition during the June 2026 quarter. He emphasized that metallurgical testing is coalescing into a coherent processing flowsheet. The April 2026 resource update increased Inferred Mineral Resources to 15.4 million tonnes at 1.00% TREO, while passive seismic surveys identified new priority exploration targets.

Beckton outlined the next steps as refining processing through metallurgical optimization and drilling to convert geophysical targets into Mineral Resources. This balanced approach integrates beneficiation and hydrometallurgical development with systematic exploration to grow the Korsnäs mineral inventory.

Rare Earth Market Dynamics Support Korsnäs Project Development

The rare earth sector is experiencing renewed global interest driven by electric vehicle growth, renewable energy infrastructure, and defense applications requiring reliable supplies of magnet rare earths like neodymium and praseodymium. European governments and the EU prioritize rare earth supply security, backing projects like Korsnäs through initiatives such as REMHub, which supports metallurgical research.

Price volatility for key rare earth elements reflects supply disruptions, trade policies, and fluctuating demand from battery and magnet manufacturers. Establishing a primary rare earth source in Finland would enhance European supply diversification and reduce import dependency. Nonetheless, project economics remain sensitive to pricing, capital expenditure, and operational costs. European Resources mitigates these risks by advancing metallurgical testing and resource definition before committing to capital-intensive development.
