About Callio Lab

Callio Lab is a new environment for underground research and other activities. The laboratory is located in the Pyhäsalmi Mine which is a copper and zinc mine. It is the oldest operating mine in Finland and the deepest active hard rock mine in Europe with the depth of 1444 metres.

Callio Lab is a part of the Callio Pyhäjärvi concept, which is a globally unique multidisciplinary operating environment. It offers a diverse range of opportunities for success for new and innovative projects and established operators seeking new horizons alike, as well as for training and R&D.

The infrastructure of the mine is excellent for various physics experiments due to the large rock overburden, but it can also serve other fields of sciences, offering unique facilities and a wealth of opportunities for a variety of scientific and commercial purposes.


FIIIUUUUU! 📣 Underground Rescue -hanke käynnisti tänään 20 vuotta seis olleen poistoilmapuhaltimen Pyhäsalmen kaivoksella. Alkaa muuten 400 -tasolla ilma liikkuun! 💪🏻 #CallioPyhajarvi #PyhasalmiMine #UndergroundRescue pic.twitter.com/wrhVCM5clK

Kaivosinfrastruktuurit ovat taloudellisesti erittäin kiinnostavia. Kaivoslain uudistamista tarvitaan. #CallioPyhajarvi #PyhasalmiMine twitter.com/Henr1kKiviniem…

What do you expect to see at the depth of 1.5 km? Physicists filling the #underground Lab 2 of @CallioPyhajarvi with their instruments. The research is done as a part of @BalticRegBSUIN project. #BSUIN @UniOulu @uniofjyvaskyla @baltic_sea_prog @Moedas #interreg #BSR #BSI pic.twitter.com/HIaGPiZ6OV Retweeted by Callio Lab
