Kylylahti Mine, Polvijärvi, Finland

Located in Northern Karelia, the mine obtained local support and was mainly seen as something positive despite its social and environmental impacts. Now, after the mine closed down, the mining company still has to restore the area.


Kylylahti was a medium-sized multi-metal mine in Eastern Finland. It was located in the rural municipality of Polvijärvi, which has about 4.500 inhabitants, situated 2 km from the municipality center. Kylylahti was an underground mine with a 113 hectares mining area positioned in the historic mining district of Outokumpu [1]. The main production of Kylylahti was copper, zinc, and gold. With less volume, it additionally produced cobalt and nickel [2]. The Kylylahti mine was founded in 1984 by Outokumpu Ltd Exploration. However, the mine did not start its operations until 2012, then owned by Altona Mining Ltd. By 2014, Kylylahti was acquired by the Swedish company Boliden Ltd. In 2015 the name changed to Boliden Kylylahti Ltd [1]. At the end of the year 2020, the mine closed down [3][4].

Project Details and Actors
Project details

Kylylahti is an underground mine with a mining area of 113 hectares located in the rural area of the municipality Polvijärvi in Eastern Finland. The Kylylahti ore was founded in 1984. It was planned that in 2007 the mine would start. However, because of the global economic and financial crisis, the mine was not built until 2010 and the mining activity did not start until 2012. The operation includes the mine in Polvijärvi and an enrichment plant in Luikonlahti at Kaavi, about 43 km from the mine area, where the ore is transported [1].

Do you consider this an environmental justice success? Was environmental justice served?:Not Sure
Briefly explain:Even if there were social and environmental impacts, the mine obtained local support and was mainly seen as something positive. Now, after the mine closed down, if justice is going to be served depends on whether the mining company successfully implements a restoration plan for the area.
