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.


Normet XS carrier is developed to provide safe, purpose-build and agile platform for several different transportation applications needed in demanding mining operations.  #CallioTestMINE #PyhasalmiMine #CallioPyhajarvi youtu.be/8mnSK0hqrMY

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

Henrika Pihlajaniemi is excited to have 'real life laboratory' studying new #adaptivelighting and #intelligentlighting in underground environment. @CallioLab #researchcommunity @UniOulu @ouluschoolofarchitecture@GTK_FI #undergroundscience pic.twitter.com/xnOewWvZV3
