South32 Gets Alaska Copper Permit Lift, Hermosa Still in Focus
South32’s Ambler Metals joint venture with Trilogy Metals secured FAST-41 permitting status for the Arctic copper-zinc project in Alaska. South32 shares fell 5.18% to A$4.21 Friday amid a wider mining sector decline. The news comes as investors weigh delays and higher costs at South32’s Hermosa project in Arizona. The Arctic project is estimated to produce 10,000 tons of ore daily over 13 years.
