Chain of custody for artisanal & small-scale mining
Every batch, traceable from the pit to the port.
Custodia records each batch from the miner who sold it to the container it ships in — sealed, GPS-checkpointed, and verifiable by anyone with a QR scan. No login required.
Available in French and English.

Built against the standards buyers already use
OECD Due Diligence Guidance
Five-step risk-based due diligence for minerals from conflict-affected areas.
ICGLR Regional Certification
Green, yellow and red site status, recorded from each monitor visit.
RMI Cobalt Refiner Standard
The records a refiner's audit asks for, kept as you work.
How it works
Due diligence built in, not bolted on afterward.
The cooperative records the work it already does. The chain of evidence builds itself as each batch moves.
- 1
Register miners and sites
Each miner gets a card; each site is mapped and classified from monitor visits. Unvisited sites stay blue — never assumed safe.
- 2
Record the sale, seal the batch
Weight, price, miner and site are captured at the depot, and the bag is sealed with a numbered tag.
- 3
Checkpoint every move
Processing, transport and export are logged with GPS and a seal check, so a break in the chain shows at once.
- 4
Anyone verifies by QR
A buyer, customs officer or auditor scans the code and sees the whole journey. No account, no app.
Safety and readiness
Incident logs, critical-controls checklists, and a readiness scorecard computed live from your own records — a dated opinion, never a certification.
