about

The reflection seismic survey

In September 2025, the Geological Survey of Finland (GTK) commissioned Geopartner Geofizyka, equipped with the STRYDE Nimble Seismic System, to acquire regional-scale reflection seismic data to support their mineral system prospectivity studies in Finland.

From navigating sensitive environments, wildlife, and protected natural areas, to operating discreetly around local communities, the survey presented a number of challenges. Despite this, the team successfully captured high-resolution seismic data to image the bedrock, revealing its geological structure and composition with exceptional clarity.

This latest campaign builds on the successful 2024 survey conducted in the Peräpohja Belt with the same project partners, further demonstrating the critical role of reflection seismic in modern mineral exploration.
