Centerra Gold Inc. (Centerra) lowered Mount Milligan’s 2026 all-in sustaining cost (AISC) guidance to $1,100 to $1,200 per ounce, citing copper by-product credits as the reason for the revised range.
Centerra also expects to meet its full-year gold and copper production targets. Its 2026 AISC guidance for Oksut is $1,850 to $1,950 per ounce.
By late October, Centerra had completed three-quarters of the infrastructure refurbishment at Thompson Creek. Centerra estimates total project capital costs at $425 million to $450 million and expects first molybdenum production by mid-2027. The company says the project remains on schedule for that milestone.
