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.
