The company says its premium-quality products continue to command higher prices than benchmark iron ore, reinforcing its long-term strategy despite softer production, Transnet logistics disruptions and a volatile operating environment.

Reporting its first-half 2026 results, it maintained full-year production and sales guidance while highlighting progress on strategic investments, including the commissioning of ultra-high dense media separation (UHDMS) technology at Sishen and the integration of renewable electricity at Kolomela.

The update comes as global steelmakers increasingly seek higher-grade iron ore to reduce emissions, positioning South African producers such as Kumba to benefit from tightening environmental regulations and the shift toward greener steel production.

Premium product continues to outperform benchmark pricing

Kumba achieved an average realised export price of US$90 per wet metric tonne, representing an 8% premium to the Fastmarkets 62% Fe benchmark price despite continued pressure on global steel demand.

Chief Executive Mpumi Zikalala says the company's product quality remained its greatest competitive advantage. “Our high iron ore quality products continue to support our premium pricing. We achieved an average realised price of US$90 per wet metric tonne (WMT), 8% above the Fastmarkets 62% iron free-on-board equivalent price, benefitting from resilient iron ore market prices and a recovery in lump premium from the lows seen earlier in the year.”

Although first-half production declined 3% to 17.7 Mt, the decrease was largely driven by lower output at Kolomela and the impact of a planned Transnet maintenance shutdown on South Africa's Ore Export Corridor. Sales volumes slipped just 1% to 18.6 Mt.

Nevertheless, Zikalala said improving mining and logistics performance gives the company confidence it will meet its full-year guidance of 31-33 Mt of production and 35-37 Mt of sales.

“Improving momentum in operational and logistics performance supports our expectation of delivering the full-year production and sales guidance.”

Transnet maintenance signals improving logistics partnership

A key feature of the first half was the first of two planned 10-day maintenance shutdowns on the Ore Export Corridor as part of Transnet's ongoing restoration programme.

The work included replacing 101 km of rail, lifting speed restrictions on parts of the export corridor and refurbishing critical equipment at Saldanha Bay Port, including the cold commissioning of Tippler 3. Although rail volumes fell during the shutdown, Kumba characterised the maintenance as an investment in improving long-term export performance.

The programme reflects the growing collaboration between Kumba and Transnet to restore South Africa's bulk export infrastructure, one of the country's most significant mining partnerships.

Operational resilience despite weather and inflation pressures

Total waste mining increased 4% to 83.5 Mt, supported by a strong recovery during the second quarter after unusually heavy rainfall and equipment productivity challenges earlier in the year. Sishen delivered a solid operational performance, increasing production 3% to 12.7 Mt, supported by improved plant stability.

Kolomela's production declined 16% to 4.9 Mt as planned stockpile drawdowns and maintenance coincided with the Transnet shutdown, although waste mining increased sharply as stripping activities accelerated ahead of future production.

The company also reported improved safety performance, with its Total Recordable Injury Frequency Rate improving from 1.18 to 0.80. “Importantly, we remain focused on what matters most, the safety of our people. We improved our TRIFR to 0.80 from 1.18 in the comparative 2025 period, demonstrating continued progress in reducing serious injuries and our unwavering commitment to eliminating fatalities across our operations.”

Cost pressures persist amid global geopolitical uncertainty

Like many miners, Kumba continues to face rising operating costs linked to geopolitical instability. The company said above-inflation increases in key mining inputs, largely attributed to ongoing conflict in the Middle East, combined with a stronger rand increased first-half unit costs.

As a result, Kumba revised the exchange-rate assumption underpinning its US dollar cost guidance from R16.00 to R16.50 per US dollar, while maintaining its underlying rand-based cost guidance for both Sishen and Kolomela.

“The cost environment remains volatile, with heightened risk associated with ongoing developments in the Middle East.”

Technology investment targets lower costs and lower-carbon steel

Beyond short-term operational performance, Kumba continues investing in technologies aimed at improving competitiveness and supporting the decarbonisation of steelmaking. At Sishen, the first UHDMS modules have entered the initial commissioning phase ahead of the main plant tie-in scheduled for August.

The technology is expected to increase product quality while improving recovery and reducing processing costs. At the same time, the company is integrating wheeled renewable electricity into its Kolomela operation as part of broader efforts to improve energy resilience and lower emissions.

High-grade ore expected to become increasingly valuable

Kumba believes structural changes in the global steel industry will continue to favour producers of higher-grade iron ore. Although steel demand remains under pressure from weak mill margins, the company noted that demand for premium products is strengthening as producers seek to reduce emissions and comply with increasingly stringent environmental regulations. Higher-grade ore enables steelmakers to reduce energy consumption and carbon emissions during blast furnace operations.

Kumba says Europe's Carbon Border Adjustment Mechanism (CBAM) is expected to accelerate this trend by increasing the cost of carbon-intensive steel production. The company's average iron content of 63.6% Fe and lump-to-fine ratio of 66:34 continue to outperform many competing exporters.

Industry analysts have increasingly argued that producers capable of supplying premium-grade iron ore are likely to command stronger pricing over the coming decade as decarbonisation reshapes global steel markets. Goldman Sachs has previously noted that high-grade iron ore premiums are likely to remain structurally supported by steelmakers' emissions reduction requirements, while Wood Mackenzie has identified premium iron ore products as critical to lowering blast furnace emissions during the transition to greener steel production.

Why this matters for Mining Indaba 2027

Kumba's results illustrate how Partnerships in Practice, the theme of Mining Indaba 2027, are becoming increasingly important to mining competitiveness.

The company's collaboration with Transnet to restore export infrastructure, investment in processing innovation through UHDMS technology, and renewable energy partnerships at Kolomela demonstrate how cooperation across logistics, technology and energy is helping miners improve resilience while positioning themselves for a lower-carbon future.

As African producers seek to supply the materials required for global industrial decarbonisation, Kumba's strategy reinforces the growing importance of quality, innovation and strategic partnerships in maintaining the continent's competitiveness in international commodity markets.
