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.
