Agreement to sell aluminium value chain assets to Alcoa

South32 has signed a binding conditional agreement to sell its aluminium value chain assets to Alcoa Corporation for an implied enterprise value of up to US$5.6B.  Alcoa will also assume related rehabilitation provisions of approximately US$1.2B.

Alcoa will acquire South32’s interests in Worsley Alumina (86%), Hillside Aluminium (100%), MRN bauxite mine (33%) (subject to exercise of pre-emptive rights held by MRN’s partners), Brazil Alumina refinery (36%) and Brazil Aluminium smelter (40%), under the Transaction. 

Celebrating 30 years of Hillside Aluminium

As Hillside Aluminium marks 30 years of operation, the milestone carries more than industrial significance. It reflects three decades of people, progress and partnership. It tells the story of a smelter that grew alongside a region and became part of its identity.
