Sydney, Jan 7, 2026, 17:35 AEDT — Market closed
Shares of South32 Ltd (S32.AX) ended 1.6% higher at A$3.84 in Sydney, with about A$86.6 million worth changing hands to keep it in the Australian Securities Exchange’s (ASX) top 20 by value traded. BHP Group added 1.0% and Rio Tinto climbed 1.6%.
The rally came as copper prices on the London Metal Exchange punched through $13,000 a metric ton this week on fears of shortages and renewed focus on supply security, Reuters reported. “Copper prices need to rise further to persuade miners to generate significant new production,” SP Angel analyst John Meyer said. Citi analysts estimate refined copper output of 26.9 million tons this year, implying a 308,000-ton deficit. Reuters
A premium — the price gap between U.S. copper futures and the London benchmark — has added fuel by pulling metal into U.S. warehouses and draining stocks elsewhere, a Reuters columnist wrote on Wednesday. A U.S. decision on copper import tariffs has been deferred until June, keeping policy headlines and the futures spread in focus.
South32 earns across a basket of commodities and has exposure to copper through its Sierra Gorda operation in Chile, alongside alumina, aluminium and manganese assets. That mix can amplify the impact of sharp moves in base metals even when there is little company-specific news in the market.
In a filing late Tuesday, South32 said it lodged notices covering unquoted securities — awards not traded on an exchange — including the granting of 14,314,934 rights to receive shares and the exercise of 276,656 rights, while 715,626 rights lapsed. Such filings are routine for employee incentive plans but can matter at the margin for dilution.
Technically, the stock has pushed higher after ending December at A$3.52, data from StockAnalysis.com showed. Traders cited support near this week’s A$3.71 low and resistance around the A$3.87 intraday high.
Risks remain on operations and costs. South32 said in December it would place its Mozal aluminium smelter in Mozambique under care and maintenance — industry shorthand for temporarily idling a plant — by March after failing to secure a power deal, and flagged a $60 million one-off cost.
