Prospech Limited (ASX: PRS) has announced further assay results from the ongoing programme of sampling and assaying of the historic Korsnäs drill core from holes completed in the 1950s, 60s, and early 70s.
Prospech managing director, Jason Beckon, commented, “Korsnäs keeps delivering standout results, with recent recognition of high-grade zones rich in critical heavy rare earth elements (HREEs) like dysprosium (Dy) and terbium (Tb).
Numerous high-grade and broad REE intersections have been returned:
- KR-272: 11.4m @ 13,383 ppm TREO from 102.7 (NdPrO2 3,982 ppm) Including 4.0m @ 32,831 ppm TREO from 106.7m (40.9 ppm Tb4O7; 227.4 ppm Dy2O3; 9,943 ppm NdPrO)
- SO-187: 17.4m @ 9,798 ppm TREO from 0.0m (NdPrO 3,087 ppm) Including 3.0m @ 48,465 ppm TREO from 11.4m (86.0 ppm Tb4O7; 313.4 ppm Dy2O3; 15,557 ppm NdPrO)
Initially developed as a lead mine, the Korsnäs project also hosts extensive rare earth element (REE) zones, which remain open both along strike and at depth. The site features a series of layered carbonatite zones, each up to 20m thick and separated by 50 to 100m along the strike.
These REE enriched zones correlate with gravity anomalies, represented as orange ellipses on the included plan. So far, five such anomalies have been identified, extending over a strike length of more than 5km.
Mr. Beckon added, “With current supply disruptions in China, securing a stable source of these materials is more important than ever. Prospech is looking to meet this need, positioning itself as a dependable future supplier of magnet critical HREEs. Our commitment to thoroughly assessing these enriched zones at Korsnäs reflects our confidence in the project’s potential and our determination to support the growing global demand for sustainable energy technologies. By developing Korsnäs as a secure supply source, we are not just meeting immediate industry needs; we’re playing a key role in strengthening the resilience of global rare earth supply chains for the long term.”
