Harmony’s Multi-Currency Refinance Clears the MAC Bridge Ahead of Eva’s Build

Harmony Gold has replaced the bridge financing behind its $1.01 billion MAC Copper acquisition with a new multi-currency debt package, reducing one of the clearest balance-sheet risks in a strategy that is rapidly turning the South African gold miner into a meaningful copper producer.

The facilities announced on July 28 comprise a $500 million US-dollar revolving credit facility, A$500 million split between revolving and term debt, and R7 billion of rand facilities. Harmony said the package will refinance its 2022 US-dollar and rand syndicated facilities, refinance the MAC Copper acquisition bridge, and support general corporate purposes. Commitments were roughly three times the targeted amount, allowing the company to scale back lenders while extending maturities and lowering funding costs.

That matters because Harmony’s copper build-out is capital intensive even after the MAC transaction itself is refinanced. Harmony acquired MAC Copper in October 2025 at an implied equity value of about $1.01 billion, gaining the CSA mine in New South Wales. The acquisition was funded with cash reserves and a $1.25 billion bridge facility, the financing now being refinanced through the new syndicated package. It is simultaneously developing the fully permitted Eva Copper project in Queensland, where approved development capital is $1.55 billion to $1.75 billion and first production is targeted for the second half of 2028.

The refinancing therefore changes the nature of the investment case. Funding is less obviously the near-term constraint; execution at CSA and construction discipline at Eva are now the bigger tests.

CSA is strategically important because it gives Harmony immediate copper production rather than only future optionality. The underground mine has a reserve life of more than 12 years and recovered grades above 3.5% copper. But the initial contribution has been weaker than the historical headline production rate. Harmony guided to 17,500 to 18,500 tonnes of copper from CSA for its financial year to June 2026, with C1 cash costs of $2.65 to $2.80 a pound. Management attributed the lower annualised output to safety stoppages and shaft rehabilitation. By comparison, CSA produced about 41,000 tonnes in calendar 2024 before Harmony acquired it.

That gap is important. The acquisition was sold partly on CSA’s ability to add immediate high-margin cash flow and diversify Harmony away from mature, deep-level South African gold operations. If integration work can restore throughput and sustain grade, CSA should help fund Eva. If not, the copper strategy will consume more balance-sheet capacity before it begins to materially strengthen group free cash flow.

Eva is the larger execution challenge. Harmony’s feasibility work targets about 65,000 tonnes of copper in concentrate annually in the first five years, with life-of-mine average production of around 60,000 tonnes of copper and 19,000 ounces of gold over more than 15 years. The project is planned as a conventional open-pit operation feeding an 18 million-tonne-per-year concentrator using crushing, grinding and flotation.

The new debt structure is better matched to that Australian spending profile. A$250 million of revolving credit and A$250 million of term debt reduce currency mismatch for Australian capital expenditure, while the rand and US-dollar facilities preserve flexibility across Harmony’s existing operations. Four of the facilities are sustainability-linked, and a rand term facility is structured as green financing.

Harmony enters this investment phase with more protection than the size of the copper programme might suggest. At its half-year results, the company reported net debt to EBITDA of just 0.18 times and liquidity of R14.8 billion. Operating profit rose 61% to R16.1 billion even though gold production fell 9% to 724,099 ounces in the first half, helped by a much stronger gold price. The board also revised its dividend framework to allow distributions of up to 50% of net free cash and declared a record R3.38 billion interim dividend.

That creates the central capital-allocation tension. Harmony is funding a multibillion-dollar copper expansion while shareholders are being promised a larger share of free cash flow. Strong gold prices make both possible for now, but the cushion depends on maintaining cash generation from the gold portfolio while CSA improves and Eva stays on budget.

Harmony said in June that it had met guided gold production for an eleventh consecutive year and entered the new financial year with strong cash generation and a growing gold-copper portfolio. Full audited FY26 results are due on August 27. The most important numbers will not be the headline gold price received. Investors should watch CSA’s revised production and cost outlook, Eva’s spending curve, net debt after the bridge refinancing, and whether the dividend policy remains intact as construction accelerates.

The refinancing is a genuine de-risking event, but it does not remove the risk from Harmony’s copper pivot. It moves the question from “can Harmony fund the strategy?” toward the harder operational question: can it make CSA perform and build Eva without surrendering the balance-sheet discipline that made the expansion financeable in the first place?
