Chain of Custody

From mine site to export clearance

Every consignment is tagged, sampled, and certified before it ever reaches a container.

Mine Site Tagging & Origin Verification

Ore is tagged at the point of extraction, recording the licensed mine site, artisan miner group, and Primary Mining License (PML) of origin.

Sampling & Laboratory Assay Testing

Representative samples are drawn and tested to verify mineral content and grade before any purchase or aggregation is confirmed.

Westfield Processing & Quality Certification

Verified ore is processed through the Westfield facility, upgrading concentrate quality and issuing certified output documentation.

Containerized Logistics & Customs Export Clearance

Finished product is weighed, bagged, and containerized under police-escorted transport, then cleared for export through customs.
