SYDNEY, June 18, 2026, 07:03 AEST
- South32 ended the session at A$4.29, gaining 0.47%. Australian miners followed the ASX higher.
- S&P/ASX 200 ended Wednesday up 0.5% at 8,966. Materials climbed 1.1%.
- Investors are eyeing copper, aluminium and manganese as well as the June-quarter production update after cost and output warnings in recent weeks.
South32 Ltd. shares will start trading again Thursday as investors look at a stronger materials sector but balance that with moves in the miner’s own stock and ongoing cost questions across aluminium and manganese.
Normal trading hadn’t started on the ASX. The main cash-market session is from around 9:59:45 a.m. to 4:00 p.m. Sydney time, with continuous order matching.
South32 ended its last session at A$4.29, gaining 0.47%, based on delayed numbers from Intelligent Investor. Despite the daily uptick, the stock was still off 5.3% from where it finished seven days back, a notable drop for a major resources player.
Australian shares climbed Wednesday, with the S&P/ASX 200 finishing up 0.5% at 8,966, hitting its best level in 20 days. Materials rallied 1.1% and mining stocks picked up 1.7%. ABC said South32 was up 0.9% and rival BHP gained 0.6%.
Keeping up with the sector could be tough for South32 if commodity prices stay strong. The stock is tied more to aluminium, alumina, manganese, copper, silver, lead and zinc than its iron ore-led peers, so it trades more in step with the “future-facing metals” trend right now. Reuters calls South32 a global mining and metals producer and lists assets like Worsley Alumina, Brazil Alumina, Brazil Aluminium, Hillside Aluminium, Sierra Gorda, Cannington, Hermosa, plus manganese mines in Australia and South Africa.

Resources stocks moved in opposite directions this week, Betashares investment strategist Tom Wickenden said. Energy dropped, but materials pushed higher. “Commodity prices have firmed,” he said. Copper, aluminium and other metals are getting a lift from AI infrastructure, defence, and energy transition spending. ABC News
South32 didn’t issue a new price-moving operations update during the local session. The most recent announcement on its exchange page was a substantial holding notice dated June 16. The next key event for the stock is the June-quarter report.
Background from April is still in play. South32 lowered its full-year Australia Manganese outlook after heavy rain and Tropical Cyclone Narelle hit GEMCO, Reuters reported. The miner also pointed to higher freight and raw material costs from Middle East tensions. At the time, South32 said these pressures might push up unit costs at Worsley Alumina and Brazil Alumina if they kept up.
Power costs remain a sticking point. South32 and Eskom said in April they’re looking at renewables for the Hillside aluminium smelter starting 2031, when the discounted electricity contract ends. Chief Operating Officer Noel Pillay said South32 needs a “viable, low-carbon energy solution” at Hillside. Reuters
There’s a risk the miners’ rally is outpacing delivery. Any weakness in copper or aluminium, oil-driven freight costs moving up, more weather problems at manganese, or delays and cost shifts at projects like Hermosa could all bring investors’ focus off the sector and back onto South32’s execution.
