Harmony reported a solid operational performance driven by improved safety metrics, higher recovered grades at Hidden Valley, and a significant increase in the average gold price received. The quarter was loss-of-life-free. On October 24, 2025, the company completed the acquisition of MAC Copper, owner of the CSA mine in Australia, marking a strategic expansion into copper production.

Material Changes vs. Prior Period
- Revenue Growth: Gold revenue increased 20% year-over-year, primarily driven by a 34% surge in the average gold price received, which offset an 8% decline in production volume.
- Production Decline: Group gold production decreased to 12,128 kg. Declines were noted at Doornkop (shaft water constraints, now resolved) and Moab Khotsong (challenging ground conditions and planned mining of the middle mine).
- Cost Increases: AISC rose 15% to R1,107,486/kg, aligned with guidance. Increases were driven by higher royalties (6% of cash operating costs vs. 4% prior year), contractor costs, and electricity inflation. Cash operating costs per kg increased 14%.
- Operational Highlights: Hidden Valley delivered exceptional results with a 31% increase in recovered grades (1.63g/t) and a 16% reduction in AISC. Underground recovered grades averaged 5.91g/t, remaining above the FY26 guidance of 5.80g/t.
- Safety: Lost-time injury frequency rate (LTIFR) improved to 4.29 from 5.57. The quarter was loss-of-life-free.
Guidance, Outlook, and Risks
Guidance and Outlook
Management remains confident in meeting full-year FY26 guidance:
- Production: 1.4 million to 1.5 million ounces.
- AISC: R1,150,000/kg to R1,220,000/kg.
- Underground Grade: Above 5.80g/t.
Updated guidance including the CSA mine contribution will be provided in the interim results (late February/early March 2026). The company is advancing the Eva Copper project and the Wafi-Golpu permitting process.
Risks and Contingencies
- Operational Risks: Challenges at Moab Khotsong due to ground conditions and water handling; delays at Mponeng and Moab Khotsong due to contractor and machinery issues.
- Market Risks: Sensitivity to gold and copper price fluctuations; exchange rate volatility (ZAR/USD).
- Regulatory and Environmental: Permitting timelines for Wafi-Golpu and Eva Copper; carbon tax liabilities; environmental regulations.
- Acquisition Integration: Risks associated with integrating the newly acquired CSA mine and achieving projected synergies.
Investor Verification Checklist
- Production vs. Guidance: Verify if the 8% production decline is fully offset by price increases to meet annual revenue targets.
- Cost Inflation: Monitor if AISC remains within the guided range (R1.15m–R1.22m/kg) given rising royalties and energy costs.
- MAC Copper Integration: Assess the timeline for CSA mine production ramp-up and its impact on the FY27 copper portfolio.
- Balance Sheet Strength: Confirm the net debt to EBITDA ratio remains below the 1.0x threshold following the MAC Copper acquisition funding.
- Safety Metrics: Track the LTIFR trend to ensure it remains below 5.00 and maintains the loss-of-life-free status.
