Sulfide Expansion Project Construction
The Çöpler Gold Mine is operated by Alacer Gold and is currently an open-pit, heap-leach operation that is producing gold from oxide ore. The Copler orebody also contains refractory sulfide ore that requires a different processing solution than heap-leaching to extract the gold. In June 2014 a Definitive Feasibility Study was completed and determined that the treatment of the sulfide ore via pressure oxidation provided the best economic return. In May 2016 construction commenced on the Çöpler Sulfide Expansion Project and first gold pour is expected in the third quarter of 2018, providing the next stage of growth for Alacer.
