Future-proof mining

Efficient water management and circular flows are important aspects in Copperstone's work for sustainable mining operations.

Efficient water management

With the reopening of the Viscaria mine, Copperstone will be working to reduce the environmental debt from the previous mining activities. Through new treatment technologies, we can help improve water quality and create circular flows for efficient water management. The water used in the mine’s production will be reused in several phases to reduce the use of resources and optimise water utilisation.

In addition to these measures, the management of bulk materials now and during production shall be carried out in such a way as to prevent future leakage to watercourses. We continuously monitor nature and waterways to ensure that environmental impact is minimised and limit values described in the environmental permit application are not exceeded.

Circular flows and ReMining

Copperstone’s ambition is to have a high utilization rate of the extracted material and to develop processes to optimize ReMining. ReMining is a method that involves extracting metals from already broken ore without making any major interventions in nature. This way, Copperstone effectively utilizes existing resources and minimizes its impact on nature. By utilizing mining waste – waste rock and tailings – the by-products can be reused as construction materials and be managed in future ReMining.

Circular and efficient resource utilization is beneficial both from an economic and environmental perspective and is an important part of Copperstone’s efforts to reduce the overall environmental impact of its operations. Smart mass management and reuse also reduce the need for resources and material procurement, which can contribute to fewer transportation trips to and from the mining area during material deliveries.


  • Minimising the amount of water affected by processing or mining activities, through the diversion of unaffected water
  • Creating processes to improve water quality in the receiving water, and minimise the risk of future leakage
  • Reusing of bulk materials (waste rock and tailings) to enable resource- and cost-efficient production and logistics
  • reMining of existing waste rock and sand deposits from previous mining activities
