Record production
The headline numbers were encouraging. South32 reported a US$121 million increase in net cash for the quarter, strengthening its balance sheet. At the same time, Brazil Alumina delivered record year-to-date production, rising 5% to 1,060kt.
Operationally, the business held up well despite a challenging backdrop. The mining company maintained production guidance across most of its portfolio, signalling resilience across key assets. One standout was Sierra Gorda, which delivered a record quarterly distribution of US$135 million.
South32 Chief Executive Officer, Graham Kerr, said:
Our teams delivered several strong operating results in the March quarter, despite adverse weather impacts.
Hillside Aluminium continued to test its maximum technical capacity, capitalising on higher aluminium prices, while
Brazil Alumina achieved record year to date production, and Sierra Gorda made a record quarterly distribution of US$135M.
Supply chains, cyclone impact
There were some weak spots. Australia Manganese saw its guidance cut due to water issues following heavy rainfall and cyclone activity. However, this appears to be a site-specific issue rather than a broader trend across the group. South32 shares also noted it is keeping a close eye on supply chains, though it reported no current diesel shortages.
Like many global miners, it is navigating higher freight costs linked to ongoing geopolitical tensions.
Safety remains a key focus. The company reported a tragic fatality at its Worsley Alumina operation in March, prompting a temporary suspension of non-critical work and an ongoing review.
Share buyback
On the investment front, South32 continues to deploy capital into growth and maintenance. It spent US$239 million on capital expenditure across the group in the first nine months of FY26, excluding major projects and joint ventures.
Shareholders are also benefiting. South32 shares completed a US$35 million on-market share buyback during the period and still has US$209 million remaining under its capital management program.
What next for South32 shares?
Looking ahead, attention is turning to its growth pipeline. South32 expects to complete a review of key milestones and capital spending for the Hermosa Taylor project in the June 2026 half, as infrastructure contracts continue to be awarded.
In the near term, management is focused on resolving operational issues, including water management at Australia Manganese and improving logistics at Mozal Aluminium and Cannington as rail access improves.
Foolish bottom line
The bigger picture remains intact. South32 is targeting long-term growth in commodities like copper, zinc, and silver, while maintaining a strong balance sheet to navigate volatility.
For investors, this update ticks several boxes: solid production, rising cash, and ongoing shareholder returns. That combination is helping explain why South32 shares continue to trend higher.
