Prospech Limited (“Prospech”) is excited to announce further impressive assay results from its ongoing sampling program at the Korsnäs Project in Finland, confirming high concentrations of critical heavy rare earth elements (HREEs), including terbium (Tb) and dysprosium (Dy). These elements are essential for manufacturing high-strength magnets used in clean energy technologies, such as electric vehicles and wind turbines.
Strong assay results confirm high HREE concentrations
Assays from 307 samples across 25 historic drill holes have returned outstanding results, including:
- KR-272: 11.4 meters at 13,383 ppm TREO (Total Rare Earth Oxides), with significant neodymium-praseodymium (NdPrO) enrichment of 3,982 ppm, including 4.0 meters at 32,831 ppm TREO featuring 40.9 ppm Tb₄O₇ and 227.4 ppm Dy₂O₃.
- SO-187: 17.4 meters at 9,798 ppm TREO from surface, including 3.0 meters at 48,465 ppm TREO, with exceptional values of 86.0 ppm Tb₄O₇ and 313.4 ppm Dy₂O₃.
These results further confirm the presence of broad, high-grade rare earth mineralisation at the Korsnäs site, with substantial concentrations of terbium (Tb) and dysprosium (Dy)—key materials for the production of high-performance magnets used in clean energy applications.
Strategic importance of heavy rare earth elements
Terbium and dysprosium are crucial for producing high-temperature magnets that can withstand the demanding conditions of electric vehicles, wind turbines, and high-efficiency motors. With ongoing supply chain disruptions, especially from China, the Korsnäs Project presents an opportunity to meet the growing European demand for these critical materials.
Jason Beckton, Managing Director of Prospech, expressed his excitement about the results:
“Korsnäs keeps delivering standout results, with recent recognition of high-grade zones rich in critical Heavy Rare Earth Elements like dysprosium (Dy) and terbium (Tb). These elements are essential for producing high-strength magnets, which are vital for clean energy technologies such as electric vehicles and wind turbines.”
“In light of current supply disruptions in China, securing a stable and reliable source of these materials is more important than ever. With Korsnäs, Prospech is positioning itself as a key player in securing Europe’s access to magnet-critical HREEs, strengthening both supply chains and the global transition to sustainable energy.”
Promising project with strong exploration potential
The Korsnäs project features extensive Rare Earth Element (REE) zones that remain open both along strike and at depth. The deposit consists of layered carbonatite structures, some up to 20 meters thick, which are correlated with gravity anomalies extending over a 5-kilometer strike length. Given its location and geology, Korsnäs is well-positioned to supply Europe’s increasing demand for locally sourced rare earth elements.
Prospech’s ongoing exploration and sampling efforts are focused on further assessing the high-grade HREE zones and advancing the project towards a potential future development, positioning Korsnäs as a key asset in securing Europe’s rare earth supply for the clean energy transition.
