Prospech Ltd Drilling Campaign Finland Targets REE Expansion

Prospech Launches Major Drilling Campaign at Finnish REE Project as Geophysics Reveals New Target Zone

Prospech Limited (ASX: PRS) has commenced a substantial 1,600-metre diamond drilling programme at its high-grade Korsnäs rare earth elements (REE) project in Finland, marking a pivotal step toward expanding its 13.5 Mt @ 1.02% TREO resource base. The Phase 2 campaign coincides with encouraging results from a passive seismic survey that has identified a promising new mineralised zone beyond the historically mined area.

The Prospech Ltd drilling campaign Finland targets down-dip and along-strike extensions of known high-grade REE lodes, with some previous intercepts delivering exceptional results including KR-285: 7.75m @ 35,063 ppm TREO and KR-247: 6.30m @ 8,087 ppm TREO. Fresh geological data will feed directly into a planned 2026 resource update, positioning Prospech to potentially expand its footprint in Europe's emerging critical minerals supply chain.

Furthermore, Managing Director Jason Beckton commented: "The commencement of this drilling programme marks a decisive step forward for Korsnäs. We now have a clear geological framework, a maturing metallurgical pathway, and geophysical tools that consistently point toward additional mineralised zones beyond the historically mined area."

Strategic Drilling Programme Targets High-Grade Extensions

The Prospech Ltd drilling campaign Finland represents a methodical approach to expanding the Korsnäs resource base through three key objectives. The 7-hole, 1,600-metre campaign focuses on down-dip and along-strike continuity testing of established high-grade REE lodes whilst enhancing geological control over Heavy Rare Earth Element (HREE) distribution patterns.

In addition, the programme builds on Prospech's comprehensive review of 479 historical drillholes, complemented by physical inspection and pXRF assessment of 275 historical cores. This systematic approach has established a robust geological framework for the current expansion drilling.

Key Target Zones Include:

The drilling specifically targets carbonatite-skarn zones up to 20 metres thick over the project's 5km strike length, where REE mineralisation occurs within steeply dipping (45-70°) metasedimentary sequences. These zones have demonstrated consistent high-grade mineralisation, with historical intercepts confirming the geological model underpinning the current drilling strategy.

Geophysics Identifies New Discovery Potential

Prospech's Horizontal-to-Vertical Spectral Ratio (HVSR) passive seismic survey has delivered compelling results that extend the exploration opportunity beyond known mineralised areas. The technique analyses ambient seismic noise to map subsurface geological contrasts, proving particularly effective at identifying carbonatite-skarn zones associated with REE mineralisation.

Key HVSR Survey Findings:

• Strong correlation with historical gravity low anomalies over known mineralised zones

• New untested covered zone identified to the east of current workings

• Successful mapping of contrasts between weathered carbonatite/skarn units and surrounding gneiss

• Phase 3 drill targets already being generated from integrated geophysical datasets

The HVSR methodology collected data using Tromino broadband sensors at 40-metre station spacing, with each location recording 15-20 minutes of ambient noise. This cost-effective approach has proven invaluable for regional targeting ahead of expensive drilling campaigns, with the new eastern zone representing a significant exploration opportunity beyond the historical mining footprint.

However, the correlation between HVSR results and historical gravity anomalies strengthens confidence in the geophysical targeting approach. This provides Prospech with a proven tool for systematic exploration across the broader Korsnäs project area.

Understanding Rare Earth Elements: Critical Materials for Modern Technology

Rare Earth Elements (REEs) comprise 17 metallic elements essential for manufacturing everything from smartphones and electric vehicles to wind turbines and defence systems. Despite their name, REEs are relatively abundant in Earth's crust but rarely occur in economically viable concentrations, making successful projects particularly valuable.

REE Classification and Applications

REEs divide into two main categories based on their atomic mass and specific applications:

Light Rare Earth Elements (LREEs):
• Include cerium, lanthanum, praseodymium, and neodymium
• Used in magnets, batteries, and catalysts
• Generally more abundant and lower-cost

Heavy Rare Earth Elements (HREEs):
• Include dysprosium, terbium, yttrium, and europium
• Critical for high-performance magnets and advanced electronics
• Scarce and command premium pricing

Why REEs Matter to Investors

• Supply concentration risk: Over 80% of global REE production occurs in China

• Demand growth: Electric vehicle and renewable energy expansion driving consumption

• Strategic importance: Governments prioritising domestic supply chain security

• High barriers to entry: Complex metallurgy and environmental considerations limit new producers

The Prospech Ltd drilling campaign Finland benefits from the country's mining-friendly jurisdiction and proximity to European end-users, potentially offering supply chain advantages over traditional Asian sources. The project's HREE enrichment proves particularly valuable, as Heavy Rare Earth Elements command premium pricing due to their specialised applications and limited global supply.

Resource Position Anchors Expansion Strategy

The Korsnäs project currently hosts a JORC (2012) Inferred Mineral Resource Estimate of 13.5 Mt @ 1.02% TREO, providing a solid foundation for the expansion drilling campaign. Historical mining activities extracted high-grade material from surface workings, leaving significant potential for modern extraction methods to target previously uneconomic zones.

Notable Historical Intercepts:

These results demonstrate consistent high-grade mineralisation across multiple zones, supporting the geological model underpinning the current drilling programme. The intercepts show both continuity and grade variation typical of carbonatite-hosted REE deposits, with the highest grades often concentrated in narrow zones within broader mineralised envelopes.

For instance, the planned 2026 resource update will incorporate new drilling data alongside advanced metallurgical testwork to potentially upgrade resource categories and expand the overall tonnage estimate. This timing aligns with European Union critical minerals initiatives, potentially positioning Korsnäs as a strategic domestic supply source.
