Sandfire rides the copper thematic through weather delays and a fatal incident

Yarra Capital Management, Ten Cap and Tectonic detail Sandfire's operational setbacks and record half-year revenue

30 Jun 2026 · 7 min read

Sandfire Resources has ridden one of the strongest copper rallies in years, with fund managers repeatedly describing it as the best pure-play exposure to the metal on the ASX even as the company works through weather delays and cost pressure at its two operating mines.

Tectonic Investment Management said in a Quarterly Report in June 2026 that Sandfire was a positive contributor to the fund's resources portfolio over the quarter, with the share price appreciating around 20%. The manager said the company's April quarterly report confirmed a further improvement in the balance sheet, swinging to a net cash position of A$76 million and trimming full-year capital expenditure guidance by A$15 million, while signing definitive transaction agreements with Havilah Resources over the Kalkaroo Copper Gold project and targeting a maiden ore reserve estimate for the A1 deposit adjacent to Motheo.

With copper continuing to benefit from structurally tightening supply and rising demand from electrification and data centre infrastructure, we remain confident in Sandfire's position as one of the more direct and attractively priced ways to gain exposure to the copper thematic on the ASX.

A consistent overweight through most of the past year

The clearest thread running through commentary on Sandfire has been Yarra Capital Management's sustained overweight position. The manager said in a Monthly Report in May 2026 that Sandfire, the pure-play copper producer, outperformed as copper prices increased by 6% during the month, repeating language it has used consistently since mid-2025: the fund continues to favour SFR as the best exposure to copper on the ASX, a commodity it likes given declining and increasingly expensive supply and its demand leverage to electrification as a key material in batteries and electric motors.

Ten Cap echoed the same thesis in an Article in April 2026, with portfolio manager Liu saying the fund used the sell-off in mining stocks to top up positions in Sandfire, BHP and Alcoa, ramping up exposure to copper and aluminium miners, adding that tight supply and demand dynamics, combined with electrification and energy security tailwinds, continue to support the long-term thesis.

Operational setbacks along the way

The path has not been smooth operationally. Glennon Small Companies said in a Monthly Report in March 2026 that Sandfire was the most significant detractor for the month, with its share price declining sharply amid a confluence of company-specific and sector-wide headwinds, including the temporary suspension of activities at its MATSA operations in Spain after a contractor employee died in an incident, alongside persistent heavy rainfall and unplanned maintenance that disrupted mining, while the Motheo copper mine in Botswana experienced delays accessing higher-grade ore.

Despite those setbacks, the manager noted Sandfire still reported a net cash balance of A$76 million at 31 March 2026, a A$63 million improvement from the December quarter, and maintained its full-year guidance range while announcing a A$15 million reduction in capital expenditure guidance, concluding the long-term copper demand thesis underpinning Sandfire's investment case remains intact, but near-term execution risk has clearly weighed on investor confidence.

Pendal Group flagged a related production miss in a Newsletter in April 2026, saying Sandfire pre-announced weaker than expected third-quarter results with copper production 17% below consensus, and that production would now be at the lower end of FY26 guidance, mostly due to weather impacts and delayed access to higher-grade ore at Motheo, though the stock still advanced that week supported by a broader market rally on ceasefire news.

Record revenue as MATSA and Motheo mature

Even with the disruptions, the underlying operating base has kept expanding. Tectonic Investment Management said in a Quarterly Report in March 2026 that Sandfire delivered record half-year revenue of A$672 million, driven by production from its MATSA operations in Spain and the Motheo copper mine in Botswana, with the production profile becoming increasingly predictable as both operations mature and access to higher-grade ore in the second half expected to support further earnings momentum.

Glennon Small Companies had described the operational base a year earlier, in a Monthly Report in September 2025, saying Sandfire's FY25 results showed a strong turnaround, with revenue rising to around USD 1.18 billion, up 26% year-on-year, copper equivalent production up 12% to 152,000 tonnes, underlying EBITDA up 46% to approximately USD 528 million at a 45% margin, and net debt reduced 69% to USD 123 million, putting the company on track to move into a net cash position within the year.

Supply disruption keeps reinforcing the thesis

The broader copper supply story has been a recurring driver of sentiment. Infinity Asset Management said in a Monthly Report in September 2025 that copper prices had continued to soar, surging above USD10,000 a tonne amid widespread supply disruptions, including accidents, flooding and social unrest at major mines such as Grasberg in Indonesia, Kamoa-Kakula in the Democratic Republic of Congo, El Teniente in Chile and Constancia in Peru, with the Grasberg outage halting around 4% of global output and unlikely to recover before 2027, reinforcing the manager's conviction in owning copper names.

The copper thematic continues to be supported by constrained supply and structural demand from electrification and data-centre build-out.

A dissenting, relative-value view

Not every manager remains convinced the stock itself, as distinct from the commodity, still offers the best value. Seneca Financial Solutions said in an Article in June 2026 that Sandfire's assets in Botswana and Spain are fine, but argued it is no longer the high-grade, premium-jurisdiction darling it was at the peak of its DeGrussa era, though it is arguably still priced as though it is, with fund managers tending to crowd into the roughly $10 billion stock given a well-publicised dearth of investable copper names on the ASX.

What managers are watching next

With Sandfire back in a net cash position, capital expenditure guidance trimmed, and a maiden ore reserve targeted for the A1 deposit alongside the newly signed Kalkaroo transaction with Havilah Resources, the managers who remain overweight say the next catalysts are confirmation that higher-grade ore access at Motheo and MATSA delivers the second-half production recovery flagged for FY26, and whether global supply disruptions at mines like Grasberg continue to underpin copper prices through the back half of the year.
