Copper producer KGHM may freeze more mines in Canada, US – CEO

Poland’s KGHM, one of the world’s biggest copper and silver producers, has no plan to sell its foreign assets but may freeze some in Canada or the United States if they require big investments, its chief executive said.

State-run KGHM, which for many years had focused only on Poland, accessed Chilean, Canadian and US metal deposits through its almost $3-billion purchase of Quadra FNX in 2012, the largest foreign acquisition by any Polish company.
