Geographical location, size and depth of the facility
Pyhäsalmi is located in central Finland 160 km south from Oulu and 180 km north of Jyväskylä or 350 km from Helsinki. The Deep laboratory facility Lab 2 at a depth of 1.44 km is especially suited for particle physics experiments requiring low cosmic ray background.
Vast tunnel network is very suitable for testing of mining and tunnelling equipment, especially at levels 75 m (Lab 1), 660 m (Lab 4) and 990 m (Lab 3). Also, old maintenance levels on 400 provide ample spaces for research.
Major rock type(s)
Granite bedrock, where the mine operation is based around massive vertical shaped volcanogenic sulfide deposit. The bedrock belongs to the Fennoscandia (Baltic) shield. Very little vibration impact from plate tectonics.
The original purpose, current use and future plans
Callio Lab is located in the Pyhäsalmi Mine, operated by First Quantum Minerals (FQM) The mine’s main products are Cu, Zn and pyrite (FS4). The mining operations shall continue to the end of 2019.
In the future, Callio Lab facilitates several types of actors, including research institutions and companies.
All of the mine’s tunnels are accessible with a truck from the 11 km long maintenance road extending to the bottom of the mine, down to 1.44 km depth
The fast elevator (3 min) from the surface to the main level (1.4 km). The maximum speed of the elevator is 12 m/s and person count is limited to 20 people.
Overall data availability
A rock mechanical study of the deep (> 1 km) part of the mine, done for the LAGUNA proposal is available at

Specialised knowledge, services
Quality system for visitors and a safe working environment down to 1.44 km. Large maintenance halls, restaurant, conferencing and social facilities on the main level at 1.4 km depth. An optical cable is available at practically all levels in the mine. GSM telephone network at the main level (1.4 km). A state-of-the-art microseismic monitoring network installed in the mine.
