Commercial production commenced at Kevitsa in the third quarter of 2012. The initial throughput rate of 5.5 Mt/a was expected to produce approximately 11,000 tonnes of nickel and 20,000 tonnes of copper annually. First Quantum Minerals submitted an environmental assessment and application to increase the plant throughput rate up to a maximum of 10 Mt/a. In March 2016, First Quantum Minerals Ltd. announced that it had entered into a sale and purchase agreement with Boliden AB to sell its Kevitsa mine. The operation would be sold to Boliden for a cash consideration of US$712 million. Ownership transferred to Boilden on 1 June.
