South32 dropped its March 2026 quarterly report today, and the numbers tell a story of resilience, record alumina production in Brazil, a landmark distribution from Sierra Gorda, and meaningful cash generation, all while the company navigated cyclones, floods, and the tragic death of a worker at Worsley Alumina.
For investors watching the South32 share price Australia closely, today’s update lands with a market cap just north of $20 billion and the stock sitting at $4.48 (as at 1 pm AEST, 22 April 2026), up $0.07 or +1.59% on the day.

A Tragedy at Worsley That Can’t Be Overlooked
Before diving into the numbers, the report opens on a sober note.
CEO Graham Kerr led his statement with condolences for Mr Simon Mukwarami, who suffered fatal injuries on 14 March during routine plant maintenance at Worsley Alumina in Western Australia. Non-critical work at the site was temporarily suspended, and the relevant authorities continue their investigation with South32’s full cooperation.
“There is no acceptable outcome other than our people going home safe and well at the end of every shift,” Kerr said.
It’s a necessary reminder that behind the quarterly production tables, real people run these operations, and safety must always come first.
Financial Snapshot: Net Cash Climbs to US$96M
Strong Cash Generation Despite Heavy Growth Capex
South32 generated net cash of US$121M during the March quarter, lifting the group’s net cash position to US$96M.
That result came despite the company investing US$158M into growth capital expenditure at the Hermosa project in Arizona, its flagship zinc-lead-silver development.
Key financial highlights for the quarter and nine months to March 2026:
- Net cash position: US$96M (up US$121M in the quarter)
- Hermosa growth capex (9M YTD): US$496M
- Total group capex (excluding EAIs and Hermosa): US$239M over 9 months
- Tax payments (excluding EAIs): US$170M over 9 months
- Interim ordinary dividend paid post-quarter: US$175M, fully franked, for the December 2025 half year
- Share buy-back (9M YTD): US$35M; 17 million shares at an average of A$3.08 per share
The company also added approximately US$100M in lease liabilities to its balance sheet across the nine-month period.
Sierra Gorda Delivers a Record Distribution
One standout moment of the quarter was Sierra Gorda, South32’s Chilean copper mine (45% share), delivering a record quarterly distribution of US$135M.
That pushed total net distributions from equity accounted investments (EAIs) to US$375M for the nine months to March 2026, comprising US$315M from Sierra Gorda and US$60M from the manganese business.
Operations Update: Records, Weather, and a Few Headwinds
Alumina and Aluminium: Broadly on Track
Brazil Alumina was the standout performer. The refinery hit a record 1,060kt in the nine months to March 2026, up 5% year-on-year, running above nameplate capacity on the back of improved plant availability. Annual guidance of 1,360kt remains unchanged.
Worsley Alumina held steady at 2,779kt for the same period despite Tropical Cyclone Narelle disrupting gas supply and plant availability during the quarter. Production fell 8% quarter-on-quarter in March, but the annual guidance of 3,750kt stays in place.
Hillside Aluminium in South Africa continued testing its maximum technical capacity, producing 538kt for the nine months, broadly flat year-on-year. The operation pushed through load-shedding challenges, and FY26 guidance of 720kt holds.
Brazil Aluminium had a tougher quarter after pot outages and energy disruptions in late 2025 hit output. Production fell 11% quarter-on-quarter to 33kt in March, though all three potlines demonstrated improved stability by quarter-end. FY26 guidance of 135kt remains intact.
Mozal Aluminium in Mozambique transitioned to care and maintenance on 15 March 2026, as previously flagged to the market. The operation exceeded its revised production guidance by 3% before the wind-down.

Cannington Battles Floods in Queensland
South32’s Cannington silver-lead-zinc mine in northwest Queensland copped significant flood damage during the quarter. Extended outages on a third-party rail line hammered sales, silver sales dropped 64% quarter-on-quarter, and lead sales fell 57%.
But the mine kept running. Ore processed actually ticked up during the quarter, and with rail access restored by the end of March, South32 expects to draw down stockpiled inventory through the June 2026 quarter. FY26 production guidance of 200.6kt (zinc equivalent) remains unchanged.
This kind of operational resilience matters for anyone tracking the South32 share price Australia through commodity cycles, as it shows the company can manage logistics disruptions without derailing core output.

Sierra Gorda — Copper Steady, Costs Set to Rise
Sierra Gorda maintained copper equivalent production at 67.2kt for the nine months to March — essentially flat year-on-year. Heavy rainfall during the March quarter temporarily suspended processing and cut into a key mining area, pulling quarterly output down 9% from the prior quarter.
The bigger news for investors: FY26 operating unit costs are expected to run 5–10% above current guidance of US$17.0 per tonne of ore processed. That reflects one-off workforce payments under new industrial agreements (now locked in until 2029), higher diesel prices, and a stronger Chilean peso.
The operation is also progressing a feasibility study for a fourth grinding line, with a potential joint final investment decision from the joint venture partners targeted for mid-CY26.
Australia Manganese — The Only Guidance Cut
Australia Manganese was the one operation that couldn’t hold its line. Elevated site water levels, wet season rainfall, and Tropical Cyclone Narelle in the quarter forced a 6% downgrade to FY26 production guidance, now set at 3,000kwmt. Water management will remain a key operational focus heading into FY27.
South Africa Manganese held its ground, sitting at 1,557kwmt for the nine-month period, with FY26 guidance of 2,000kwmt unchanged.

South32 Share Price Australia: A Strong 2026 So Far
Investors keeping tabs on the South32 share price Australia have had plenty to smile about in 2026. The stock has surged on the back of stronger commodity prices, solid operational execution, and a cleaner balance sheet after South32’s exit from coal and other non-core assets in recent years.

| Market Cap | ~$20.1B |
The 71.65% one-year return is striking, it outpaces the broader ASX 200 by more than 58 percentage points, a significant outperformance that reflects both company-specific execution and a strong commodity tailwind.
