Sandfire Reports 5% YTD Copper Equivalent Decline, Maintains FY26 Guidance

Fatality Overshadows Safety Progress

Sandfire Resources (ASX:SFR) reported a sobering rise in its Total Recordable Injury Frequency (TRIF) to 1.5 by the end of March 2026, up from 1.3 six months prior, driven by the first fatality in its history. A 34-year-old contractor tragically died while installing a polyethylene paste distribution line at the Magdalena mine. The incident has prompted emergency responses and ongoing investigations, with the company emphasizing its commitment to strengthening safety culture and risk management across all operations.

This fatal event starkly highlights the hazards of stored energy in mining environments and the critical need for rigorous controls and leadership behaviours to prevent such tragedies. Sandfire’s CEO Brendan Harris expressed deep sympathy and noted that the company continues to support those affected.

Production Impacted by Weather and Ore Quality

Operationally, Sandfire’s Group copper equivalent (CuEq) production for Q3 FY26 came in at 34.5kt, bringing the year-to-date total to 106.5kt, a 5% decline compared to the same period last year. MATSA’s output was constrained by unusually heavy rainfall and unplanned maintenance, which reduced plant utilisation and crusher performance, pushing its annualised ore processing rate to a three-year low of 4.2 million tonnes in the quarter. Despite this, March saw a recovery in mining and processing rates, with the operation expected to comfortably meet the lower half of its 91kt to 101kt FY26 guidance.

Meanwhile, Motheo in Botswana delivered 12.8kt CuEq in the quarter, a 6% increase quarter-on-quarter but down 10% year-on-year due to delays transitioning to higher grade ore. Notably, Motheo achieved record annualised mining and processing rates of 6.5Mt and 6.1Mt respectively, signaling operational momentum that is expected to support production at the bottom end of its 58kt to 64kt guidance for the full year.

The challenges at both sites echo the complexities of managing ore grade transitions and weather disruptions simultaneously. Sandfire has adjusted Motheo’s ore processing guidance upward slightly to 5.8Mt for FY26, reflecting sustained throughput improvements.

Cost Management Amid Inflation and Geopolitical Risks

Despite softer production, Sandfire maintained its operating cost discipline. MATSA’s underlying operating cost was $98 million in Q3 FY26, aligned with annual guidance, while its C1 unit cost impressively declined to $0.29 per pound, helped by elevated by-product prices, particularly silver which averaged $86 per ounce. The 6% increase in unit operating cost per tonne processed was primarily due to reduced throughput.

Motheo’s underlying operating unit cost remained steady at $44 per tonne. However, the company flagged potential risks to input costs and supply chains stemming from the ongoing conflict in the Middle East, which could impact fuel prices, freight rates, and foreign exchange. Both operations are currently well supplied but remain vigilant to rapid changes.

Financial Strength and Strategic Progress

Financially, Sandfire posted record Q3 sales revenue of $408 million and underlying EBITDA of $220 million, finishing the quarter with a net cash balance of $76 million, up from $13 million at the end of December 2025. This strong cash position follows a significant $46.5 million payment to Havilah Resources as part of the Kalkaroo Copper-Gold project acquisition and $26.1 million in tax instalments in Botswana.

The company’s strategic focus on growth is underscored by its advancement of the Kalkaroo project in South Australia. Since executing definitive agreements with Havilah Resources in February 2026, Sandfire has laid the groundwork for a ~$70 million pre-feasibility study scheduled for completion in H2 FY28. Early activities include onboarding key personnel, preparing camp facilities, and securing contractors for a ~130km drilling program. This initiative complements ongoing regional exploration in the Iberian Pyrite Belt and Kalahari Copper Belt, where drilling activity has accelerated despite some prior safety-related suspensions.

Sandfire’s approach to managing operational challenges and capital investment is reflected in the recent decision to reduce FY26 capital expenditure guidance by $15 million to $225 million, a move detailed in a prior update that also maintained copper equivalent production guidance in the lower half of the range. This balance of prudence and growth ambition is critical as the company navigates global uncertainties.

Notably, Sandfire’s recent copper equivalent guidance update and capex cut provides valuable context on the company’s calibrated response to evolving operational realities and market conditions.

Sustainability Initiatives Continue

On the sustainability front, construction of MATSA’s new tailings storage facility is progressing despite weather delays, with commissioning expected in the first half of FY27. This infrastructure is vital for extending the mine’s operational life beyond 2040. Meanwhile, Motheo is developing a 21 MW solar power facility to supply approximately 30% of its electricity needs, supporting decarbonisation and energy security goals, with operations slated to start in Q3 FY27.

Sandfire also recently hosted a sustainability briefing highlighting cultural heritage management at its now-closed DeGrussa mine, reflecting ongoing commitments to environmental and social governance.
