Magnetotelluric (MT) surveys provide valuable insights into the electrical resistivity structure of the subsurface, supporting the investigation of geological structures from near-surface to greater depths.

Our projects may define what we do, but our people define who we are.

Recently, GRM-services Oy Ltd gathered in Hämeenlinna for our annual Staff Day. The day combined company updates, discussions, team activities, and networking opportunities for colleagues from different teams and locations.

Representing GRM-services Oy Ltd at Mining Finland booth, Antti Kivinen, Antoine Michel, and Keijo Nuutinen connected with clients, partners, and industry peers on ongoing and upcoming work — including survey projects in Sweden, potential opportunities in Spain, and future magnetotelluric campaigns.

At GRM-services Oy Ltd, we provide 2D and 3D subsurface survey solutions using IP and resistivity methods for mineral exploration projects across different terrains and operational environments.

With experience across 12 countries under diverse geological and operational conditions, we combine a Finland-based foundation with a born-global approach.

Our value is driven by operational reliability, data quality, and the ability to work effectively across different environments.

At GRM-services Oy Ltd, occupational safety is deeply rooted in our culture. We are committed to continuously improving our tools and practices to support safer and smarter work in the field.

GRM-services Oy Ltd is turning 10! 🎉

This year, we are celebrating a full decade of geophysics and rock mechanics.

Over the past ten years, we have completed more than 600 projects, operated in 12 different countries, and built a strong domestic and international network.

Gravity Surveys in Northern Sweden.

The year has started at full speed for GRM-services Oy Ltd, with a strong workload ahead in 2026.

FEM2025 is just around the corner!
Along with a great lineup of sessions, the event offers a fantastic opportunity to explore the latest know-how in mineral exploration.
If you’re attending, make sure to stop by booth B40 and have a chat with our experts!

The FLEM survey on a remote Norwegian mountain required helicopter support. The transmitter was equipped with a multiplexer, enabling simultaneous two-loop measurements that saved time and effort. Borehole surveys with the DigiAtlantis probe further clarified the mineralization geometry, all against the backdrop of stunning scenery.
