South32 Ltd Looks to Bypass China for Arizona Zinc as Hermosa Nears U.S. Approval
South32 plans to send zinc from its $2.16 billion Hermosa mine in Arizona to North American smelters, not China, after a key U.S. Forest Service draft approval on March 6. The company signed a non-binding letter of intent with Teck Resources to supply its British Columbia smelter. The federal review runs through April 20, with a final decision expected in July. South32 says Hermosa could produce up to five critical minerals.
