South32 to invest $2.16bn in Arizona’s Hermosa project

South32 has secured board approval to spend $2.16bn (A$3.32bn) to develop the zinc-lead-silver deposit at the Hermosa project, located in a mining district in the Patagonia Mountains of southern Arizona, US.

The Hermosa project is distinguished as the only advanced US mining project that can produce two federally designated critical minerals, zinc and manganese, which are pivotal for the clean energy sector.

The project, which is recognised as the first critical minerals mining project under the US’ FAST-41 permitting process, is poised to become one of the largest zinc producers globally.

Covering an area of more than 600 acres, the project is said to integrate sustainability and the latest technology in its underground mine design, incorporating automation to enhance efficiency and reduce greenhouse gas emissions.

The investment from South32 will finance the construction of critical infrastructure including water management systems, power, site facilities and underground development.
