Responsible sourcing you can audit.
A strong commitment to environmental stewardship, governance and community impact — built into how we mine, buy and export.
Our commitments
Environment
- No mercury and no cyanide in our own extraction or processing
- Environmental authorizations obtained before each stage of activity
- Sediment control, fuel containment and waste segregation in the field
- Progressive rehabilitation of disturbed ground
Social
- Written contracts, lawful wages and freedom of association
- No child labor and no forced labor — in operations or supply chain
- Consultation with local and customary authorities before site entry
- Local hiring and procurement, and a community grievance mechanism
Governance
- Lot-level chain of custody: seller identity, origin, weight and assay
- Sanctions screening against UN, US, EU and UK lists
- Exports through official DRC channels, with duties and royalties paid
- E&S risk as a standing management-committee item
The standards we work to
Traceable from mine to buyer.
Every lot carries a documented chain of custody — a purchase record identifying the seller and site of origin, an assay certificate, and a lot number that follows the material into its export dossier. Suppliers are screened before the first purchase, red flags are escalated, and no shipment is released without a complete lot file.
We cooperate with the supply-chain audits of our buyers and refiners, and will publish an annual responsible-sourcing summary.
