Harmony Gold Achieves Milestone with First Copper Concentrate Production

Harmony Gold Mining Company has successfully produced its first copper concentrate at its South African operations, achieving a milestone in its efforts to diversify its mineral output. The initial batch, amounting to 1,250 metric tons, was extracted from the company’s existing infrastructure at the Carletonville complex, with a copper grade of 18.5%—a level consistent with medium-grade ore deposits. This move aligns with the firm’s broader strategy to reduce reliance on gold and capitalize on rising demand for copper in renewable energy and electric vehicle manufacturing. The development comes amid increasing global demand for copper, driven by infrastructure upgrades and decarbonization initiatives. According to recent industry data, global copper demand reached 30.4 million metric tons in 2025, with supply growth lagging behind. Harmony’s entry into copper concentrate production adds incremental capacity, though it represents a modest addition to the overall market. The company plans to scale output gradually, aiming for 5,000 metric tons annually within two years. The move is expected to influence Harmony’s financial profile, as copper typically commands higher margins than gold in current market conditions. Shares of Harmony Gold (HG=F) rose 3.7% in early trading on the Johannesburg Stock Exchange following the announcement. The stock’s performance was supported by a broader uptick in materials sector indices, with the Copper ETF (COPX) gaining 2.3% and the VanEck Africa Index (XAB) increasing 1.8%. Market analysts note that while the output volume is not disruptive to global supply chains, the strategic shift could enhance Harmony’s long-term resilience. The company’s ability to leverage existing mining infrastructure for copper extraction reduces capital expenditure risk and supports operational efficiency. Additional exploration at Carletonville and nearby sites is underway to identify further copper-rich zones.
