KCA was awarded the EPCM contract for this expansion project in 2015 and completed the Engineering for the project in 2016.

​The project is designed as a 5,600 tonnes per day two-stage crush, rod mill / verti-mill, filtration, mixing and agglomeration plant. The pre-existing Merrill-Crowe plant is utilized for metal extraction and the agglomerated product is blended with crushed ore from the pre-existing heap leach circuit and delivered to conveyors stacking ore onto the new heap leach pad.

​KCA completed construction and commissioning efforts of the expansion in 2017.
