Prospech Uncovers High-Grade REE at Korsnäs, Strengthening European Supply Prospects

Key Highlights:

• Assays confirm high-grade rare earth element (REE) mineralisation at the Korsnäs Project in Finland.
• Significant intercepts over 1% TREO, with peak values reaching 4.6% TREO.
• Heavy REE enrichment, including Terbium (61.3 ppm) and Dysprosium (234.2 ppm), reinforcing strategic importance.
• 4,035 samples from 237 drill holes analyzed, covering 6,453 metres of historic drilling.
• Mineral Resource Estimate being updated, with metallurgical studies underway in partnership with the EU-backed REMHub project.

Korsnäs: A Rising REE Powerhouse

Prospech Limited (ASX: PRS) has delivered outstanding assay results from its Korsnäs Rare Earth Elements (REE) project in Finland, confirming extensive high-grade mineralisation. With peak TREO values hitting 4.6%, Korsnäs is emerging as a strategic asset for Europe’s critical mineral supply chain.

Managing Director Jason Beckton emphasized the significance of these results, stating:

            “Korsnäs is now recognized as a significant REE project. The consistency of high-grade mineralisation, along with heavy rare earth enrichment, strengthens our confidence in its long-term value.”

Impressive Intercepts Confirm High-Grade Potential

Recent assays have revealed multiple high-grade intercepts, reinforcing the continuity of mineralisation at depth and along strike:

• KR-285: 7.7m @ 35,063 ppm TREO (NdPrO 6,291 ppm), including:
• 6.3m @ 41,581 ppm TREO (NdPrO 7,443 ppm)
• 1.2m @ 46,042 ppm TREO (NdPrO 7,594 ppm)
• KR-247: 6.3m @ 8,087 ppm TREO (NdPrO 2,318 ppm), including:
• 3.1m @ 11,589 ppm TREO (NdPrO 3,274 ppm)
• SO-080: 28.7m @ 2,945 ppm TREO (NdPrO 815 ppm), including:
• 1.30m @ 10,938 ppm TREO (NdPrO 3,298 ppm)
• SO-099: 1.4m @ 13,894 ppm TREO (NdPrO 4,199 ppm), including:
• 0.40m @ 28,498 ppm TREO (NdPrO 8,766 ppm)

These intercepts highlight the richness of the deposit, confirming that Korsnäs remains open for further expansion both along strike and at depth.

Strategic Importance for Europe’s REE Supply

With the global shift towards securing critical mineral resources, Korsnäs stands out as a key REE asset in Europe. The project’s heavy rare earth enrichment makes it particularly valuable, given the increasing demand for Terbium and Dysprosium in high-performance magnets and green energy technologies.

Next Steps: Mineral Resource Update & Metallurgical Testwork

Prospech is now proceeding with an updated Mineral Resource Estimate, leveraging these final assay results. Additionally, the company is progressing metallurgical testwork in collaboration with the University of Oulu and GTK Mintek, under the EU-backed REMHub initiative.
