Opportunity

Amidst a shifting global economic terrain, the evolving future of the gold industry is giving rise to multi-faceted growth strategies for leading mineral producers.1

Harmony Gold Mining Company Limited (Harmony) is a world-leading gold mining specialist.2 Over its 75 years of operations, Harmony has become South Africa’s largest gold producer by volume, with over 20 years of experience operating across the APAC region.3 The company is developing a growing international copper footprint as a part of its expansion strategy, diversifying its production offering to facilitate the global shift toward renewable energy infrastructure.4

In 2025, the price of gold surged by 66 per cent – its steepest climb since 19795 – driven by the interconnected global factors of geopolitical tensions, inflation, central bank purchasing, currency volatility and supply constraints.6 South Africa boasts a strong history as a leading gold producer, and its gold mining companies are leveraging this opportunity to capitalise on favourable gold market conditions by implementing strategies to diversify their jurisdiction and/or commodity exposure.


Approach

Macquarie Capital acted as exclusive financial adviser to Harmony Gold on its $US1.03 billion acquisition of MAC Copper, increasing its portfolio weighting to copper - a critical mineral for the electrification and decarbonisation of the global economy.

MAC Copper owned and operated the high-grade CSA Mine in New South Wales, Australia, which produced over 40,000 tonnes of copper in 2024.7

Macquarie Capital leveraged its extensive industry expertise as Africa’s leading M&A mining adviser8 to assist Harmony in assessing the opportunity and implementing its acquisition strategy. This builds on Macquarie Capital’s previous advisory services in the region, including:

  • Advising MMG on its ~$US1.9 billion acquisition of Khoemacau Copper Mine in the Kalahari Copper Belt in Botswana.
  • Advising Impala Platinum on its R43 billion (~$US2.1 billion) acquisition of Royal Bafokeng Platinum.
  • Advising South32 on its divestment of South Africa Energy Coal.

The team’s capabilities were further bolstered through collaboration with Macquarie’s Commodities and Global Markets Mining Finance team, who acted as an initial mandated lead arranger and underwriter for the $US1.25 billion acquisition-linked bridge finance facility. By leveraging their respective targeted expertise, both funding and transaction advisory services were delivered throughout the acquisition.

Macquarie Capital utilised a cross-regional advisory team throughout Australia and EMEA that had previous engagements with Harmony, working with the company to navigate a series of transaction complexities, including managing stakeholder negotiations amidst a period of heightened market volatility. Macquarie Capital facilitated the successful structuring of the transaction, despite numerous strategic shareholdings in MAC Copper and existing complex financing arrangements.

Outcome

Harmony’s acquisition of MAC Copper via a Jersey scheme arrangement for $US1.03 billion represents the company’s largest ever acquisition, whilst securing the CSA Mine - one of Australia’s last pure-play copper assets that produces at scale.

The addition of immediate copper production from the CSA Mine will support the development of Harmony’s regional growth assets, and will benefit from the demand for copper across electric vehicles and power grid infrastructure.9

The transaction provides a strong strategic fit for Harmony’s growth aspirations, creating a de-risked and geographically diversified gold and copper portfolio. Through CSA and Harmony’s Eva Copper project, Harmony has the potential to become a ~100,000 tonnes per annum copper producer on the East Coast of Australia within the next five years.4
