Asante Gold released an update on progress made on its sulphide plant at the Bibiani Gold Mine in the republic of Ghana.
“This is a year of executing our strategic plan to allocate significant capital to our mining and processing operations at both Bibiani and Chirano. With the finances now in hand, we expect to grow long-term gold production to 450,000 to 500,000 ounces of gold per year,” said Dave Anthony, president and CEO.
“With construction and commissioning of the Bibiani sulphide treatment plant complete, we are focused on the next phase, which moves the plant into operation, ramp-up, testing and optimization to achieve 92 percent recovery and enhance Bibiani’s growth profile,” added Anthony.
Construction on the Bibiani sulphide plant first began in Q4 2024. The objective of this facility is to liberate and recover the gold that occurs within sulphide mineralization. For the ore at Bibiani that is below 110 meter depth, approximately 30 percent of the gold occurs within sulphide mineralization and measures 35 microns.
The process flowsheet for the sulphide plant includes flotation, regrind of flotation concentrate to 25 microns, use of Aachen reactor technology to provide elevated oxygen levels in the high intensity leach and carbon in pulp (CIP) for gold recovery. The flotation tailings and sulphide treatment plant tailings return to the carbon in leach (CIL) plant for further treatment. This process is expected to increase gold recovery significantly, from 60 percent to 92 percent, keeping in line with the Bibiani technical report published in April 2024.
The sulphide treatment plant commenced 12 hour per day operations on September 27, 2025. The company expects to move to a 24-hour per day operation on September 30, 2025. Optimization will proceed during October and 92 percent recovery is expected to be reached in late October 2025.
