South32 drops 5%, Alaska project lifts copper outlook but cost concerns remain
South32 closed Friday at A$4.21, down 5.18%, ahead of Monday’s Australian session. The company faces higher capital costs at its Hermosa project in Arizona, now estimated at $3.3 billion, with first output delayed to late 2028. The Arctic Project in Alaska, a joint venture with Trilogy Metals, gained U.S. FAST-41 permitting status last week. Broader metals and mining shares also fell Friday amid weaker copper and gold prices.
