Plant Expansion: Construction Progress Update

The expansion nearing completion will permit Dynacor to maintain a maximum gold recovery rate and boost processing volumes to 430 tonnes per day (TPD). Due to a significant rise in ore supply over the last number of months, Dynacor has been steadily growing its throughput levels from its nameplate capacity of 300 TPD. As of today, the plant is operating at its maximum rate of 345 TPD. The expansion, which began in March, is progressing as planned and will be complete in the coming days.
