B2Gold has successfully commissioned the mill expansion at the Fekola mine to 7.5 million metric tons per year (mt/y), one month ahead of schedule. The expansion, which included all major construction activities and execution of a process performance test, was scheduled to be completed on September 30.
Four days after startup, the five-day mill performance test was conducted from August 26 to August 30. The results of the performance test exceeded design throughput, gold recovery, grind and availability over the five-day day period, according to the company. Minor, outstanding construction work is expected to be completed by mid-September.
