Low-cost gold producer Alacer Gold is targeting higher output in 2019, following a transitional year during which the company completed the construction of a sulphide plant at its Çöpler gold mine, in Turkey. The miner on Tuesday set its production guidance for 2019 at between 320 000 oz and 380 000 oz, at an all-in sustaining cost (AISC) of $675/oz to $725/oz. This compares with 170 865 oz of gold produced in 2018, at an AISC of $615/oz of oxide ore.
