Codelco目前可以投資20多億美元建設(shè)該項(xiàng)目。其中安第斯北(Andes Norte)投資19億，安第斯塔(Andesita)投資0.76億美元，迪亞曼特(Diamante)投資1.01億美元。
地質(zhì)條件復(fù)雜，加上建設(shè)過(guò)程中由于爆炸引起的傷亡事件，公司不得不尋找替代方案對(duì)建設(shè)計(jì)劃進(jìn)行調(diào)整，最終選擇建設(shè)三個(gè)礦段。
主礦段為安第斯北，位于目前開(kāi)采的8中段以下250米。
因此，項(xiàng)目總投資從之前的30億美元上升到50億美元。
Codelco公司首席執(zhí)行官內(nèi)爾森·皮薩羅(Nelson Pizarro)向議會(huì)介紹了建設(shè)方案，證實(shí)項(xiàng)目已完成46.7%。預(yù)計(jì)2023年投產(chǎn)，新增年產(chǎn)銅量3.5萬(wàn)噸，完全達(dá)產(chǎn)后可新增礦石產(chǎn)能14萬(wàn)噸/日。
新礦段建成后，可將特尼恩特銅礦壽命延長(zhǎng)50年。
