Harmony Secures Full Ownership of CSA Copper Mine

Harmony Gold's Historic Copper Mine Acquisition Reshapes Strategic Direction

Harmony Gold Mining Company has successfully completed its transformative US$1.01 billion acquisition of MAC Copper Limited, marking the moment when harmony takes full ownership of csa copper mine in New South Wales, Australia. This landmark transaction represents South Africa's largest gold producer's most significant strategic pivot, fundamentally reshaping its operational portfolio from a gold-focused enterprise into a diversified precious and base metals powerhouse.

The acquisition, finalised on October 24, 2025, through a Jersey law Scheme of Arrangement, marks a decisive moment in global mining industry evolution. According to Harmony's completed acquisition, the deal was structured at US$12.25 per share, providing MAC Copper shareholders with a 20.7% premium above market value at the time of announcement.

Financial Architecture Behind the Billion-Dollar Deal

Harmony's acquisition strategy demonstrates sophisticated financial engineering, combining multiple funding sources to maintain optimal capital structure. The company utilised a US$1.25 billion bridge facility alongside existing cash reserves, ensuring the transaction maintains its debt-to-EBITDA ratio below 1.0x despite the substantial investment.

Transaction Structure Breakdown:

The financing structure reflects institutional confidence in Harmony's strategic vision, with major financial institutions backing the bridge facility arrangement. Furthermore, this approach allows Harmony to preserve financial flexibility while executing one of the mining industry's largest base metals acquisitions in recent years.

CSA Mine: A Century-Plus Legacy of Copper Production

The CSA copper mine represents more than just an acquisition target; it embodies nearly 150 years of continuous copper production heritage in Australia's established mining landscape. Located in central western New South Wales, this underground operation extends to depths of 1.9 kilometres, positioning it among Australia's deepest active mining operations.

CSA Mine Operational Excellence Metrics:

The mine's exceptional cost structure places it in the lower quartile of global copper producers, with C1 cash costs of US$1.92 per pound after by-product credits. This competitive positioning becomes increasingly valuable as global copper supply outlook accelerates driven by electrification trends and renewable energy infrastructure development.

Underground Mining Excellence and Technical Innovation

CSA's underground operations utilise advanced mining methodologies optimised for deep extraction. The mine employs sub-level cave mining techniques, maximising ore recovery while maintaining operational safety at extreme depths. Recent infrastructure investments include:

• Advanced ventilation systems supporting deep-level operations

• Automated material handling reducing manual intervention

• Digital monitoring systems for real-time operational optimisation

• Enhanced safety protocols for high-pressure, high-temperature environments

Strategic Rationale: Diversification Beyond Gold Dependency

Harmony's copper acquisition addresses multiple strategic imperatives that extend far beyond simple portfolio diversification. The move positions the company to capitalise on structural demand shifts while reducing exposure to gold price volatility.

Core Strategic Drivers:

• Electrification Megatrend Exposure: Copper demand projected to grow 70% by 2040

• Revenue Stream Stabilisation: Dual-commodity production reduces single-metal risk

• Jurisdictional Diversification: Australian Tier-1 jurisdiction reduces regulatory risk

• Cash Flow Predictability: Copper's industrial demand profile offers steadier pricing

• ESG Alignment: Supporting clean energy transition infrastructure

Production Scaling Ambitions and Growth Trajectory

Harmony has established ambitious production targets, aiming for 100,000 tonnes of annual copper production within five years. This represents a 144% increase from current CSA production levels, combining existing operations with the company's Eva Copper Project in Queensland.
