MAC Copper supports acquisition by Harmony Gold Mining Company

Johannesburg: Harmony Gold Mining Company has announced that MAC Copper Limited has received the requisite majority of votes from its shareholders in favour of the proposed sale of 100% of its issued share capital to Harmony Gold (Australia) Pty Ltd.

MAC Copper is the owner of the high-grade CSA Copper mine (CSA) in Cobar, New South Wales, Australia. This is further to the approvals obtained from The South African Reserve Bank (SARB) on 5 August 2025 and the Australian Foreign Investment Review Board on 19 August 2025.

“This acquisition accelerates Harmony’s strategy of adding to our portfolio of high-margin, long-life ore bodies. MAC Copper serves as a strategic lever, moving us towards a more resilient, geographically diverse asset portfolio, with copper enhancing cash flow resilience.

With our proven expertise in underground mining and exploration, we will unlock further value from CSA,” said Beyers Nel, CEO of Harmony.

Post the finalisation of the remaining conditions, we anticipate that Harmony will take control of the asset towards the end of October 2025.
