Responsible sourcing
Critical minerals only belong in a buyer's supply chain once they can be traced and trusted. We apply risk-based due diligence to every supplier and shipment, informed by the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals.
Known suppliers
Every producer is identified and screened before we buy.
Traceable lots
Each lot can be traced from the producing site to the port of loading.
Sanctions screening
Counterparties are checked against international sanctions lists.
Independent verification
Weights and grades are confirmed by third-party inspection, not by us.

3TG minerals
Tin, tantalum, tungsten and gold are 3TG minerals. For these, we keep chain-of-custody records from the producing site to the port, and share the information buyers need for their conflict-minerals reporting.
Supporting documentation is shared with qualified buyers after first contact.
