MMG sanctions $900m Khoemacau expansion to 130,000 tpa copper
MMG has sanctioned a roughly $900 million expansion of its Khoemacau copper mine in Botswana's Kalahari Copper Belt, including pre-2026 expenditure. The project lifts capacity to about 130,000 tonnes of copper in concentrate per year with over 4 million ounces of silver, via a new 4.5 Mtpa processing plant and three underground mines at Zone 5 North, Mango and Zeta North-East. Total milling capacity exceeds 8.0 Mtpa. 2026 guidance is 48,000 - 53,000 tonnes of copper in concentrate, first concentrate is targeted in the first half of 2028. Life-of-mine average C1 cash costs are forecast below $1.60/lb, down from $2.05/lb in mid-2025.
