Dual-listed Newmont Goldcorp’s Ahafo mill expansion, in Ghana, has achieved commercial production, on schedule and within budget of about $175-million. Combined with the Subika underground mine, which was successfully completed in November 2018, the mill expansion is expected to increase Ahafo’s average gold production to between 550 000 oz/y and 650 000 oz/y through to 2024, while lowering life-of-mine processing costs.
