South32 Limited is a Perth-headquartered, dual/triple-listed (ASX/JSE/LSE) diversified miner spun off from BHP in 2015.
Group exposure score is 64 including 1 tracked subsidiary — standalone is 68.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 1 supplier. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
South32 Annual Report 2025 states Alumina from Worsley Alumina is currently exported to our Hillside Aluminium and Mozal Aluminium smelters and other smelters around the world, and that Hillside cost is driven by alumina supplied by our Worsley Alumina refinery. Worsley refinery is at Collie/Worsley, Western Australia (South32 86%, Japan Alumina Associates 14%); Hillside Aluminium (100% South32) is at Richards Bay, South Africa. Intra-group transfer, no tonnage split disclosed; Worsley FY25 saleable alumina output 3,727kt.
Scope. Absence of a counterparty here is not evidence that none exists — most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
Another tracked dossier names this company as a counterparty in its own sourced disclosure — this platform never wrote these rows on this company's own page, they are read here inverted from the dossier that disclosed them. This is a partial view: 990 additional named-counterparty rows across the corpus could not be matched to a tracked dossier by name at all (mostly non-Latin legal names), so the true count is higher than what renders here.
South32 is developing the Hermosa critical-minerals project (Arizona); Normet supplies SmartDrive battery-electric underground equipment, remote monitoring and training for the project. Equipment quantities/contract value not disclosed on this page.
Scope. This section is inverted evidence: each linked dossier wrote the original row about itself, describing its own relationship to this company. It is never a claim this company itself disclosed. Absence here is not evidence of no relationship — most of the corpus has no named-counterparty block at all yet.
This company sits on the supply side for 5 of its 5 materials — a restriction on those is a tailwind, not a headwind.
As a producer, policy pressure across its produced materials is flat.
Descriptive trend in official policy actions on this company’s materials — a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
🇿🇦 ZA accounts for 100% of severity-weighted pressure.
