About exploration

Pyhäsalmi Mine Oy has conducted ore exploration in the surroundings of the mine since 2004. Before that, Outokumpu Oy conducted exploration in the area from 1957 onwards. The company has valid claims and exploration permits amounting to 453 hectares (numbering 6), all of which are located in the areas adjacent to the mine in Pyhäjärvi. In exploration, Pyhäsalmi Mine makes use of deep drilling and geophysical measurements. A total of 1.6km of deep drilling was carried out in 2015. The company does not currently have exploration applications subject to appeal. Pyhäsalmi Mine OY also has four other mining concessions; Vuohtojoki (Kärsämäki), Hallaperä (Kiuruvesi), Rauhala (Ylivieska) and Mullikkoräme (Pyhäjärvi). In 2015, no exploration was carried out in these concessions (totalling 143ha).

  • CUPP (Center for Underground Physics in Pyhäsalmi) continued its operations at the mine, including the EMMA experiment investigating cosmic radiation.
  • Calliolab collaboration with Pyhäjärvi Kehitys Oy continued Calliolab seeks to bring to various research projects and similar to the mine after its operation are discontinued.
    Collaboration projects between the mine and Pyhäjärven Kehitys Oy include a clarification entitled Kaivos Energiavarastona (“A mine as an energy storage”) which will be completed during 2016, and the Data Center Kaivoksessa project (“A data center in a mine”) which explores opportunities to locate a data centre in a mine/mining area.In 2015, Pyhäsalmi Mine Oy also provided financial support to the following projects/research projects under the TEKES Green Mining programme (an indiscernible and smart mine).


– IMineWa (Intelligent Mine Water Management) project managed by Lappeenranta University of Technology. This project seeks to improve the management of mining water by improving/developing existing technologies and by creating new ones for the treatment of mining water.

– GEOSULF project managed by the University of Oulu This project seeks to find a method which can be used to prevent the dissolution of detrimental substances from sulphidic extractive waste.

– SAM (Sustainable Acceptable Mining) project. During the project, a tool was developed which could be used to assess the efficiency of the mine’s water usage.

In 2015, a TEKES project aimed at developing safety: Turvallisuudesta Työhyvinvointia, laatua ja tuottavuutta (“Well-being at work, quality and productivity through safety”).
