HARMONY ADDS IMMEDIATE CASH FLOW FROM COPPER PRODUCTION BY ACQUIRING MAC COPPER LIMITED, OWNER OF THE HIGH-GRADE CSA COPPER MINE IN AUSTRALIA
Johannesburg, Tuesday, 27 May 2025
1.Introduction
Harmony is pleased to announce that it has entered into a binding agreement to acquire, through its wholly owned Australian subsidiary Harmony Gold (Australia) Pty Limited, 100% of the securities in MAC Copper Limited (“MAC”), a Jersey-registered company, at a price of US$12.25 per MAC share in cash ("Transaction"). The Transaction implies a total equity value for MAC of US$1.03 billion1 (approximately R18.4 billion)2. MAC is listed on the New York Stock Exchange (“NYSE”) under the symbol MTAL and the Australian Securities Exchange (“ASX”) under the symbol MAC (trading as CHESS Depositary Interests (“CDIs”)).3
MAC has a 100% interest in the CSA Copper Mine (“CSA”), its sole asset, which is located ~700km west-northwest of Sydney in the Cobar Region of New South Wales, Australia.
“The acquisition of the CSA Copper Mine in Australia is significant as it introduces a high-quality, established underground producing copper asset to the Harmony portfolio. CSA is one of the highest-grade copper mines in Australia, producing ~41kt of copper in calendar year 2024. The operation is a logical fit with the portfolio given it meets Harmony’s core investment criteria, including increasing free cash flow generation while improving margins at long-term expected commodity prices. We believe that Harmony is well positioned to leverage its expertise in underground mining to further enhance operations. Furthermore, the Transaction represents a significant step forward in transforming Harmony into an increasingly de-risked, higher-quality, global gold and copper producer through
disciplined and effective capital allocation,” said Beyers Nel, Chief Executive Officer.
2. Strategic rationale
Harmony is a specialist mining company and is transforming into a global gold and copper producer. With over 75 years of experience, its strategic objective is to produce safe, profitable ounces and improve margins through operational excellence and value-accretive acquisitions. Harmony has successfully acquired and integrated a number of quality operations and projects in recent years, including full ownership of Hidden Valley in Papua New Guinea (“PNG”) in 2016, Moab Khotsong in 2018, Mponeng and Mine Waste Solutions in 2020, and the Eva Copper Project in Queensland, Australia in 2022.
This Transaction aligns with Harmony's successful strategy of value-accretive acquisitions and further supports Harmony's strategic objective of transitioning into a low-cost, global gold and copper mining company through disciplined and effective capital allocation.
3.Transaction highlights include:
•De-risking Harmony through diversification into a premium, established copper asset in a tier 1 jurisdiction: CSA is one of the highest-grade copper mines in Australia, producing upwards of 40ktpa of copper in concentrate. The Transaction is consistent with Harmony’s geographic focus.
•Driving margin expansion: In 2024, CSA had a C1 Cash Cost (after by-product credits) and an All-in Sustaining Cost (after by-product credits) of US$1.92/lb and US$2.92/lb respectively, underpinning an operating free cash flow margin of 36%.
•Delivers immediate cash flows: CSA grows Harmony’s presence and cash flow generation in Australasia alongside Hidden Valley in PNG, which further supports the proposed development of Eva Copper and Harmony's Wafi-Golpu project in PNG.
•Long mine life with significant exploration potential: CSA is a high-quality, established asset with a proven track record of reserve replacement. CSA has a current reserve life of +12 years and has
maintained a stable resource base over the last decade before significant resource and reserve growth achieved by MAC since 2023.
•Highly complementary to Harmony’s portfolio: Harmony has had a presence in Australasia for over 20 years, and benefits from an established and experienced team based in our regional headquarters in Brisbane, which manages Hidden Valley in PNG and is progressing Eva Copper in North-West Queensland. Together with Eva Copper, Harmony has the potential to produce ~100ktpa of copper on the East Coast of Australia within the next 5 years.
•Robust balance sheet with strong cash flow generation: Net debt/EBITDA will remain within Harmony’s target leverage range, being well below 1.0x post-closing of the Transaction. Harmony’s strong balance sheet will enable the pursuit of further growth opportunities at CSA.
•Significant upside opportunities: CSA’s grade is increasing with depth as drilling continues to define the high-grade lenses. MAC has also identified significant mineralization in the upper parts of CSA (approximately 150m below surface level) representing an additional mining area, called the Merrin Mine. Development of the Merrin Mine is underway, with first ore expected in the December Quarter 2025. An inaugural zinc resource was announced in February 2025 with a reserve to follow.
4.Description and terms of the Transaction
The offer price of US$12.25 per MAC share in cash implies a fully diluted equity value for MAC of US$1.03 billion1,4 (approximately R18.4 billion)2. The offer price represents a premium of:
•20.7% to MAC’s last closing price of US$10.15 per share on the NYSE as at Friday, 23 May 2025; and
•32.1% to the 30-day volume weighted average price of US$9.28 per share on the NYSE as at Friday, 23 May 2025.
The Transaction will be implemented pursuant to a scheme of arrangement under Jersey law ("Scheme") according to an Implementation Deed ("Implementation Deed") entered into between Harmony, Harmony Gold (Australia) Pty Limited and MAC.
The MAC board unanimously recommends that MAC shareholders vote in favour of the Scheme, in the absence of a Superior Proposal (as defined in the Implementation Deed). Each of MAC’s directors (who together hold or control 2.4% of MAC’s total current fully paid ordinary shares and CDIs on issue)5 also intend to vote their MAC shares in favour of the Scheme, subject to the same qualification.
Several of MAC’s key shareholders, Fourth Sail Group (“Fourth Sail”), Osisko Bermuda Limited (“Osisko”), Sprott Resource Lending II (Collector) LP (“Sprott”), Victor Smorgon Group (“Victor Smorgon”), and BEP Special Situations VI LLC (“Bluescape”) (who together hold or control an additional 20.1% of MAC shares and CDIs on issue) have confirmed to MAC that they will vote all of the MAC shares or CDIs that they directly or indirectly own or control at the time of the Scheme meeting in favour of the Scheme, in the absence of a Superior Proposal.6
5.Overview of MAC
MAC is an Australian-based copper producer that wholly owns and operates CSA, one of the highest-grade copper mines in Australia. This underground mine is located 11 kilometres north-west of Cobar, central western New South Wales, in Australia. MAC is also developing the Merrin Mine, which is located in the upper parts of CSA and is expected to provide additional copper and zinc production. MAC holds a total of 756 square kilometres of tenements with the potential to expand and extend CSA’s future mine life.
The Cobar Region in NSW has a long history of mining and benefits from well-established infrastructure, permitting framework and a highly skilled labour force.
CSA is one of Australia’s longest operating copper mines with a history dating back almost 150 years. The mine is 1.9km deep and has a reserve grade of 3.4% Cu.
In the year ended 31 December 2024, CSA produced over 41,000 tonnes of copper at a C1 Cash Cost (after by-product credits) of US$1.92/lb.
The Transaction follows comprehensive due diligence undertaken by Harmony over several months. This included four site visits by technical experts, management and board members. Harmony has been impressed by MAC’s culture,
operational improvements and the cost reductions the team has made since its purchase of the mine in 2023. Harmony will bring its skill set in deep underground mining to continue and grow these initiatives, including ventilation upgrades, development of the Merrin Mine and a well-funded exploration programme.
6.Transaction funding
Harmony intends to fund the Transaction with a US$1.25 billion bridge facility (“Bridge Facility”) together with existing cash reserves.
Harmony has entered into a binding commitment letter with the following banks to arrange and underwrite the Bridge Facility:
•Citibank, N.A., London Branch: Global Coordinator, Initial Mandated Lead Arranger and Bookrunner

The Bridge Facility has a tenure of 364 days plus a 6-month extension, exercisable at the discretion of Harmony.
Harmony reported a record net cash position of R10,831 million (US$592 million) as at 31 March 2025 and had R20,853 million (US$1,140 million) available in cash and undrawn facilities. MAC reported cash and cash equivalents of US$75 million and total net debt of US$150 million as at 31 March 2025.
Harmony has various alternative re-financing options available, and in due course will refinance the Bridge Facility with the most competitive and value enhancing source of financing.
7.Osisko and Glencore arrangements
On completion of the Transaction, Harmony will assume the obligations of MAC under:
•the silver purchase agreement (“Silver Stream”) with Osisko pursuant to which Osisko receives refined silver equal to 100% of the payable silver production from CSA and makes ongoing payments equal to 4% of the spot silver price per ounce at the time of delivery;
•the copper purchase agreement (“Copper Stream”) with Osisko pursuant to which Osisko receives refined copper equal to 2.25% to 4.875% of the payable copper production from CSA, which amounts may be reduced through the exercise of a buy-down option, with Osisko making ongoing payments equal to 4% of the spot copper price per tonne at the time of delivery;
•the royalty deed (“Royalty Arrangement”) with Glencore Operations Australia Pty Limited (“Glencore”) pursuant to which Glencore is entitled to a 1.5% net smelter return royalty over the life of the CSA mine; and
•the sale and purchase agreement between MAC and Glencore relating to US$150 million of contingent payments, where a one-off payment of US$75 million is due in the event that the copper price averages more than US$4.25/lb for 18 continuous months at any stage during the life of the CSA mine and a further one-off payment of US$75 million in the event that the copper price averages more than US$4.50/lb for 24 continuous months during the life of the CSA mine.
