On September 2015, all mining and processing operations were suspended and all facilities were placed on care and maintenance status. In November 2016, a 3rd party contractor completed a pre-feasibility study of the project to finish the upgrade in order to process various types of mill feeds at a nominal rate of 8,000 t/d.
In 2017, Ausenco was selected to provide EPCM services for the execution of the process plant upgrades. The main design work included an upgrade of the comminution circuit to allow the processing of various mill feeds at a nominal processing rate of 8,000 tpd.
Project solutions and approach
Ausenco integrated the upgrades into the existing facilities, including the crushing, grinding and reagents, along with new processing circuits. The former CIL circuit was converted to a hybrid leach/CIP circuit to enhance gold recovery.
This brownfield project used new and refurbished equipment to increase throughput and recovery rates, resulting in an economically viable plant. First gold was poured in May 2019
