Self-reporting shows the version suppliers want you to see.
Operational risk is often three layers deep and twelve months behind.
Critical minerals sit at the centre of electrification, batteries, EVs, storage, and industrial decarbonisation. But the supply chains behind them are far messier than a finished product suggests.
My guest is Johan Oosthuizen, a responsible sourcing specialist based in South Africa. He works across mining, operations, supply chain governance, regulatory due diligence, and the gap between policy expectations and what happens on the ground. That gap matters because resilience does not fail in slide decks. It fails at extraction sites, contractor interfaces, community relationships, supplier capability, and weak data.
The pressure is rising. Battery demand is growing fast, regulation is tightening, and downstream OEMs are being asked to prove where materials come from, how they were produced, and whether suppliers can stand up to scrutiny. If compliance is treated as second-tier spend, risk builds quietly. Then it shows up as cost, disruption, reputational damage, lost premium, or blocked market access.
What changed my thinking was Johan’s framing that governance risk can be bigger than geology risk. The minerals may be in the ground, but that does not mean they are socioeconomically suitable to mine. He also explains why a mine is not one company digging a hole, but an ecosystem of contractors, labour providers, suppliers, communities, investors, and regulators. A large mine may directly employ 1,000 to 2,000 people, yet need around 10,000 people in its first tier alone.
Audit data should not sit in a compliance folder gathering digital dust. Used properly, it can shape procurement strategy, supplier development, ESG performance, operational resilience, and supply chain visibility.
For senior supply chain, procurement, operations, sustainability, and risk leaders making decisions under cost, regulatory, and disruption pressure.
If you’re dealing with supplier risk or critical mineral visibility on the ground, I’d like to hear what is proving hardest.
