Critical Minerals
Building Responsible Resilient Supply Chains from Mine to Market
Why critical minerals need a different approach to due diligence
Critical minerals carry risks that generic supply chain due diligence doesn’t fully capture. Production is concentrated in a small number of countries, several of them fragile or high-risk jurisdictions. Large-scale operations frequently sit alongside artisanal and small-scale mining, raising coexistence and formalisation questions that don’t arise in most other supply chains. And the regulatory pace is accelerating fast – the CSDDD, EU Battery Regulation and CSRD are reshaping what “due diligence” is legally required to mean, often faster than internal compliance teams can track.
See our Audits and Standards Hub and Regulatory Compliance page for more information.
Our track record spans the full value chain – from major mining companies to downstream manufacturers and brands, across gold, copper, cobalt and other critical minerals supply chains.
Our expertise is backed by the TDi Digital Platform – which turns due diligence from a static, periodic exercise into continuous monitoring. See the platform.
