KGHM to decide about expanding mine in Chile next year

Poland's largest copper miner KGHM said on Friday  it will decide at the beginning of the next year about the potential second stage of exploration at its Chilean mine Sierra Gorda, the biggest KGHM's overseas asset. Sierra Gorda is a joint venture of KGHM (55 percent stake) and Japanese Sumimoto (45 percent stake), that is why the Polish miner will "make all of the decision alongside Sumimoto," Herbert Wirth, the CEO at KGHM said. The mine was launched a year ago, its copper and molybdenum disposals are one of the richest in the world.
