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.


Callio TestMINE initiative has been started. What an adventure and vision, Callio FutureMINE, the best in the world test environment for mining technology and innovations in Pyhäsalmi mine. #TestMINE #CallioPyhajarvi #PyhasalmiMine youtu.be/AD9LpM6Ls-0

Kohta se alkaa. Voiko tätä syödä? Ohjelma jossa on nuriseva kokki ja innosta tärisevä tiedemies matkalla ruoantuotannon tulevaisuuteen ja mahdollisuuksiin. Osa toimii, osa ei. #voikotätäsyödä? #yleareena pic.twitter.com/gLKqFkyPVf Retweeted by Callio Lab

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

Researchers show example in #recycling: instead of having everything new and costly the EMMA cosmic ray experiment uses of detectors from former experiments at @CERN #LEP_DELPHI & @KITKarlsruhe KASCADE #ResearchImpactEU @CallioLab @UniOulu @uniofjyvaskyla pic.twitter.com/ODtyfVTXgv Retweeted by Callio Lab
