Harmony Gold’s $1.08 Billion MAC Copper Acquisition Financing Strategy

How is Harmony Gold Financing the MAC Copper Acquisition?

Harmony Gold has significantly strengthened its financial position ahead of its $1.08 billion (R19 billion) acquisition of MAC Copper in Australia. The company reported a remarkable 285% increase in net cash to R11.1 billion for the year ending June 2025, creating a total available liquidity of nearly R21 billion. This robust financial foundation positions Harmony strategically for completing the transaction without requiring equity funding.

According to CEO Beyers Nel, the company plans to utilize "a balanced mix of debt or debt-like instruments to maintain an optimal capital structure and further lower our cost of capital" rather than pursuing equity funding options for this acquisition.

The company's strategic debt financing approach reflects confidence in its current financial health and ability to manage additional debt without diluting shareholder value. This approach aligns with industry trends where mining companies increasingly seek to optimize their capital structure through debt rather than equity issuances during periods of expansion.

Financial Strategy Behind the Acquisition

The financial approach behind Harmony's MAC Copper acquisition demonstrates careful planning and strategic positioning:

• Cash reserves: R11.1 billion net cash position (285% increase year-over-year)
• Total liquidity: Nearly R21 billion available
• Funding approach: Debt-focused financing without equity dilution
• Transaction value: $1.08 billion (approximately R19 billion)

Financial analysts note that Harmony's strong cash position provides flexibility in how the company structures its acquisition financing. By avoiding equity issuance, the company preserves ownership stakes for existing shareholders while potentially benefiting from the tax advantages of debt financing.

Industry experts point out that Harmony's debt-to-equity ratio remains favorable compared to industry peers, giving the company significant headroom to take on additional debt without overleveraging its balance sheet. This financial discipline reflects management's conservative approach to capital raising strategies.

What Assets Does MAC Copper Bring to Harmony's Portfolio?

The MAC Copper acquisition represents a significant step in Harmony's strategic diversification beyond gold into copper assets. MAC Copper's primary asset is the CSA Copper Mine in New South Wales, Australia—one of the country's oldest and highest-grade underground copper operations.

CSA has been operating since the 1880s and consistently produces high-grade copper concentrate with silver credits. The mine utilizes sublevel open stoping and has an established infrastructure network that allows for efficient extraction and processing of ore.

This acquisition aligns with Harmony's broader copper strategy loan deal, which began with its earlier purchase of the Eva Copper project in 2022. Together, these assets position Harmony to become a meaningful player in the copper market.

Key MAC Copper Assets and Strategic Value

The strategic value of the MAC Copper acquisition extends beyond simple asset accumulation:

• CSA Copper Mine: High-grade underground copper operation in Australia with average grades exceeding 2.5% copper
• Production potential: Contributes to Harmony's goal of producing approximately 100,000 tonnes of copper annually within five years
• Strategic fit: Complements the Eva Copper project in Harmony's growing copper portfolio
• Geographic diversification: Expands Harmony's presence in Australia's mining sector

The CSA mine offers immediate production capability, allowing Harmony to establish a copper revenue stream while developing its greenfield Eva Copper project. This balanced approach provides both immediate returns and long-term growth potential.

Mining industry analysts have highlighted the complementary nature of these assets, with CSA providing immediate cash flow while Eva represents future growth potential with its larger resource base but longer development timeline.

How Does the Acquisition Fit into Harmony's Growth Strategy?

The MAC Copper acquisition represents just one component of Harmony's ambitious growth and diversification strategy. The company is pursuing a multi-phased approach to expanding both its gold and copper operations across multiple geographies.

This strategic diversification helps Harmony reduce its traditional heavy reliance on South African gold production while positioning the company to benefit from growing global demand for copper price insights driven by electrification trends, renewable energy expansion, and infrastructure development.

Eva Copper Project Development

Following the MAC Copper acquisition, Harmony plans to focus on developing the Eva Copper project, which requires greenfield development. Recent drilling results have significantly enhanced the project's resource estimates:

• 31% increase in estimated contained copper to 1.9 million tonnes
• 12% rise in estimated contained gold to 492,000 ounces (compared to initial 2024 resource declaration)

These improved resource estimates strengthen the economic case for Eva's development, potentially enhancing the project's net present value and internal rate of return calculations. The company has conducted extensive metallurgical testing confirming favorable processing characteristics for the Eva ore.

The final investment decision for Eva Copper is expected later in 2025, with first production targeted for 2028. CEO Nel indicated that Eva "will come with its own funding solution," with more details to be provided upon the final investment decision.

Wafi-Golpu: The "Biggie" on the Horizon

Beyond MAC Copper and Eva, Harmony's most significant potential growth project remains the Wafi-Golpu copper-gold project in Papua New Guinea, a joint venture with US gold major Newmont. The company reports "steady progress" in negotiations with the Papua New Guinea government regarding the required special mining lease (SML), though no definitive timeline has been established.

Wafi-Golpu represents a world-class deposit with estimated resources of 13 million ounces of gold and 4.4 million tonnes of copper. The project would utilize block cave mining methods to efficiently extract the deep ore body.

Earlier in 2025, Nel expressed confidence in Harmony's financial capacity, stating that "Harmony has never been in a better position to finance and build Wafi-Golpu," addressing longstanding analyst concerns about funding this capital-intensive project.

Mining sector specialists note that Wafi-Golpu's development would transform Harmony from a mid-tier gold producer with copper exposure to a major diversified metals company with significant production of both gold and copper.

What Financial Results Support Harmony's Expansion Plans?

Harmony's aggressive growth strategy is underpinned by strong financial performance, with gold revenues rising 20% to R73.9 billion in the fiscal year ending June 2025. This revenue growth could have been even higher if not offset by a realized loss of R4.6 billion on the company's gold hedge book.

The company's strong operating cash flow provides the foundation for its ambitious expansion plans while maintaining financial stability. Harmony's improved financial metrics reflect both operational improvements and favorable gold price environments.

Financial Highlights Supporting Growth

Despite these strong results, the company faced challenges with rising costs, reporting a 17% increase in all-in sustaining costs (AISC). Nel attributed approximately 9% of this increase to mining cost inflation, with the remainder resulting from lower gold production impacts on unit costs and increased sustaining capital requirements.

Industry analysts point out that cost management will be crucial for Harmony as it expands into copper production, particularly as the company will need to establish new operational expertise in copper mining and processing while maintaining discipline in its traditional gold operations.

How Does Harmony Manage Financial Risk During Expansion?

Harmony maintains a conservative approach to financial risk management, particularly through its hedging strategy. The company continues to hedge up to 30% of its gold production over a rolling 36-month period to "lock-on margins" and provide financial stability during periods of elevated capital investment.

This approach to risk management provides a financial safety net during the company's ambitious expansion phase, ensuring predictable cash flow even during periods of commodity price volatility.

This hedging approach, while resulting in a R4.6 billion realized loss in the recent financial year due to rising gold prices, forms part of what Nel describes as a "prudent strategy" that provides "financial stability and flexibility during a phase of elevated capital investment."

Risk Management Approaches

Harmony employs several complementary approaches to manage financial and operational risks:

• Gold hedging: 30% of production hedged on a rolling 36-month basis
• Cost discipline: Focus on controlling mining costs despite inflationary pressures
• Balanced funding: Mix of debt instruments rather than equity dilution
• Phased development: Staggered approach to major capital projects

Mining financial experts note that Harmony's conservative hedging strategy, while potentially limiting upside during gold price rallies, provides crucial downside protection and cash flow predictability during periods of significant capital investment.

The company's approach to staggering major project developments—MAC Copper acquisition first, followed by Eva development, and eventually Wafi-Golpu—helps manage capital allocation more effectively while allowing the company to apply learnings from each project to subsequent developments.

What Challenges Does Harmony Face in Its Copper Expansion?

While Harmony positions itself for copper investment overview, several challenges remain in executing its strategy:

Cost Management Concerns

The 17% increase in all-in sustaining costs (AISC) raises questions about Harmony's ability to control expenses during its expansion phase. While management attributes this partly to mining inflation (9%) and partly to production and capital factors, maintaining cost discipline will be crucial as the company diversifies.

Industry experts point to several factors driving mining cost inflation in Australia, including rising energy costs, labor shortages in skilled mining roles, and increased regulatory compliance expenses. Harmony will need to navigate these challenges while establishing new operational capabilities in copper production.

Project Development Timelines

The development schedule for Eva Copper (targeting 2028 production) and the uncertain timeline for Wafi-Golpu present execution risks. Delays in either project could impact Harmony's copper production growth targets and financial projections.

Mining project development specialists note that large-scale mining projects frequently face timeline extensions due to permitting delays, construction challenges, or technical complications during commissioning. Harmony's phased approach helps mitigate some of these risks by not overcommitting resources simultaneously.

Regulatory and Government Relations

The ongoing negotiations with the Papua New Guinea government regarding the special mining lease for Wafi-Golpu highlight the regulatory complexities of international mining development. Similar challenges could affect other aspects of Harmony's international expansion.

Mining industry analysts familiar with Papua New Guinea note that the country has a complex history with resource development projects, with government stakeholders balancing desires for economic development with ensuring appropriate benefits flow to local communities and the national government.

How Will Harmony's Portfolio Change After These Acquisitions?

Harmony's strategic moves signal a significant transformation from a primarily South African gold producer to a diversified precious and base metals company with substantial international exposure. The addition of MAC Copper and development of Eva Copper will meaningfully increase the company's copper production profile.

This portfolio transformation represents one of the most significant strategic shifts in Harmony's corporate history, fundamentally changing both its commodity exposure and geographic footprint.

By 2028-2030, assuming successful execution of current plans, Harmony's portfolio will likely feature:

• A significant copper production component from Australian operations
• Potential additional copper and gold production from Wafi-Golpu
• A more geographically diverse asset base spanning South Africa, Australia, and potentially Papua New Guinea
• A more balanced revenue mix between gold and copper

Mining sector analysts suggest this transformation could potentially lead to a re-rating of Harmony's stock as it evolves from a primarily South African gold producer to a more diversified international metals company with exposure to both precious and base metals markets.

FAQ: Harmony Gold's Copper Expansion Strategy

Why is Harmony diversifying into copper?

Harmony is strategically expanding into copper to diversify its portfolio beyond gold, capitalize on growing copper demand driven by electrification and energy transition trends, and establish a presence in commodities with strong long-term fundamentals. This diversification helps reduce the company's exposure to gold price volatility while positioning it in markets with favorable supply-demand dynamics.
