US DEPARTMENT OF ENERGY GRANT FOR CLARK BATTERY-GRADE MANGANESE

South32 Limited (ASX / LSE / JSE: S32; ADR: SOUHY) (South32) advises that our Hermosa project located in Arizona, United States,
has been selected for a US$166M award negotiation from the US Department of Energy (DOE).

Hermosa's Clark deposit is currently the only advanced project in the United States with a clear pathway to produce battery-grade
manganese from locally sourced ore for the North American electric vehicle battery market.

The grant from the DOE's Battery Materials Processing and Battery Manufacturing program will support the potential development
of a commercial-scale manganese production facility. On a cost-share basis and subject to final negotiation, the DOE will provide 30
per cent of the cost of the manganese production facility, up to the grant award of US$166M.

While subject to further study, construction of the facility and the development of Clark represents a significant opportunity to
establish a North American supply chain of battery-grade manganese in a phased approach in line with market development.

We are engaging potential customers to advance product qualifications for battery manufacturing, including potential agreements
for future supply following the signing of multiple non-binding Memorandums of Understanding.

Construction of a decline at Clark to enable bulk sampling through a demonstration plant and further underground exploration is
underway, with decline access scheduled for the end of CY25. The US Department of Defense is supporting this work through a
US$20M grant from the Defense Production Act Investment Program.

South32 Chief Executive Office Graham Kerr said, "We welcome this grant from the US Department of Energy, which recognises
Clark's potential to supply battery-grade manganese to the emerging North American market.

"Hermosa represents a regional scale project with the potential to produce commodities critical to a low-carbon future across
multiple deposits for decades to come.

"Following final investment approval earlier                  in    the     year,   construction    of    our    large-scale,    long-life
Taylor zinc-lead-silver project is progressing as planned.

"Our investment in Taylor will unlock value for future growth options, including Clark, by establishing significant shared infrastructure.

"In addition to Taylor and Clark, we are continuing further exploration programs at Peake to test the potential for a continuous
copper system connecting Peake and Taylor."
