DENDROBIUM NEXT DOMAIN UPDATE

South32 Limited (ASX, LSE, JSE: S32; ADR: SOUHY) (South32) announces today that we will not proceed with an investment in the Dendrobium Next Domain (DND) project at Illawarra Metallurgical Coal following our consideration of recently completed study work and extensive analysis of alternatives.

While our work on the project demonstrated the potential to meaningfully extend the life of the Dendrobium mine, expected returns from the ~US$700M up-front capital expenditure estimate are not sufficient to support an investment relative to alternatives considered for the complex.

With this decision, we will now focus on continuing to optimise Dendrobium and the broader Illawarra Metallurgical Coal complex to extend the mine life within approved domains. This work includes existing plans for Appin, where we have been investing to support its transition to a single longwall from FY25, bringing further operating and capital efficiencies. Looking forward, our investments at Appin include planned work to install additional ventilation capacity to enable mining in the current Area 7 until at least 2039[1]. Although this ~US$260M[2] investment remains subject to South32 Board approval, it has been incorporated in our previously announced FY23 and FY24 Safe and reliable capital expenditure guidance[3].

Average annual saleable production of ~5.5Mt with Operating unit costs of ~US$105/t to US$120/t is expected from the current configuration beyond FY23[4], with further improvements to be targeted to sustainably bring unit costs to the bottom of the range.

South32 Chief Executive Officer, Graham Kerr said: "Our decision today follows an extensive analysis of the alternatives for Dendrobium together with the anticipated returns from the up-front capital investment which would be required.

"Over the past 18 months we have made significant progress actively reshaping our portfolio and this decision increases our capacity to direct capital towards other opportunities. This includes our world class development options in North America that have the potential to underpin a significant growth profile to produce metals critical to a low carbon future, servicing strategically important supply chains."
