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 FY234, 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
