MMG Limited has approved the feasibility study and sanctioned construction of a major expansion at the Khoemacau Copper Mine in Botswana, committing approximately US$900 million to the project, including pre-2026 expenditure.
The expansion will increase annual production capacity to about 130,000 tonnes of copper in concentrate, with associated silver output expected to exceed 4 million ounces. Mining will be extended to the Zone 5 North, Mango, and Zeta North-East deposits, alongside the development of a new 4.5 million-tonne-per-annum processing plant, lifting total milling capacity to more than 8.0 million tonnes per annum.
First copper concentrate from the expanded operation is targeted for the first half of 2028. Operational efficiency is expected to improve materially, with life-of-mine average C1 cash costs forecast to fall below US$1.60 per pound, compared with US$2.05 per pound in the six months to 30 June 2025.
The project strengthens the scale and long-term profitability of MMG’s copper portfolio. Further growth potential of up to 200,000 tonnes of copper per annum has been identified through ongoing exploration, with a pre-feasibility study for the next phase scheduled to commence in 2026.
