The Pyhäsalmi Mine, located in the town of Pyhäjärvi, central Finland, is one of the deepest metal mines in Europe reaching 1,445 metres underground. The copper-zinc mine was opened in 1962 by Outokumpu, sold to Canadian Inmet Mining Corporation in 2002, and obtained by Canadian mining corporation First Quantum Minerals in 2013. Underground mining activities in Pyhäsalmi are projected to end in 2019. This, however, will not be the end of the mine as a focal point of human activity.

As mining will end in Pyhäsalmi, a globally unique multidisciplinary operating environment, Callio, will take over the mine along with its facilities and the associated underground infrastructure. The mine and the surrounding brownfield area offer a diverse range of opportunities for success for new and innovative projects and established operators seeking new horizons. The infrastructure at the mine is globally unique and provides a very potential platform for production, product development and trial run activities for very versatile business activities both on ground and underground. Business opportunities at Callio include, but are not restricted to, the following:

  • Bio-energy terminal
  • Growing – plants, edible insects, fish, mushrooms
  • Storage and aging – cheese, liquors and vegetables
  • Energy storage – pumped hydro storage
  • Data center – cyber center & security
  • Research, development & innovation

All future business activities conducted in the Pyhäsalmi Mine will be in need of assistance what comes to learning correct underground workplace safety procedures, rescue protocols and training. Muon Solutions Ltd joins the network of Callio Pyhäjärvi service providers for these tasks.
