Editorial interest 82/100 Selection signal · not a rating of the site

Custodia presents a chain-of-custody system for tracking artisanal mineral lots from a mine site through export.

Landing page captured for the 2026-09-29 issue.
For
Artisanal mining cooperatives, mineral buyers, auditors, and regulators
Worth noticing
The page says unvisited sites stay blue rather than being presumed safe; its QR checks are presented as requiring no account or app.

Field notes

The workflow connects miner and site records to sale details, numbered bag seals, and later processing, transport, and export checkpoints. Site status uses green, yellow, or red classifications, while unvisited sites remain blue; a separate readiness view covers governance, safety measures, incidents, and verified documents. The page explicitly says that readiness view is an opinion based on a cooperative’s own data, not a certification.
