South32’s Hermosa project in Arizona has been notified of a US$166 million grant from the U.S. Department of Energy (DOE) to support development of a commercial-scale battery-grade manganese facility.

The funding will support construction of a key part of the project, which aims to strengthen U.S. domestic supply of critical battery materials for EV and energy storage applications.

According to the project timeline, early development and construction activities are progressing through 2025–2027, with zinc-production targeted around 2027.
