目前由于礦石品位下降，Codelco的銅礦產(chǎn)量開(kāi)始下滑，其中去年的產(chǎn)量已經(jīng)從前年的173萬(wàn)噸下降至168萬(wàn)噸。今年第一季度產(chǎn)量為37.09萬(wàn)噸，比去年第四季度下降27%，同比也下降17%，降至十年來(lái)新低。所以公司致力于通過(guò)Chuquicamata銅礦地下項(xiàng)目來(lái)提高產(chǎn)量。
同時(shí)由于項(xiàng)目從露天作業(yè)轉(zhuǎn)為地下作業(yè)，露天銅礦將于2020年關(guān)閉，疊加公司表示目前三分之一的勞動(dòng)力都由機(jī)器取代，故該項(xiàng)目大約將裁員1700人。
