Chain of Custody Best Practices: Preserving Consignment Integrity from Drill Rig to Receiving Bay

Integrity Begins at the Drill Site

Defensible assay results depend fundamentally on what happens before samples reach the laboratory doors. Damaged sample bags, obliterated sample numbers, or broken seals introduce irrecoverable data loss.

Tamper-Evident Geosealing Protocols

Every consignment leaving remote exploration camps should be packaged in heavy-gauge poly bags secured with uniquely numbered, tamper-evident security tags. A formal Chain of Custody (CoC) document detailing sample IDs, bag counts, and dispatch dates must accompany the manifest.

Receiving Bay Reconciliation

Upon arrival at RVA Labs Mwanza receiving bay, batches undergo immediate weigh-in, security seal verification, and electronic barcode logging. Any discrepancy triggers a digital notification to the exploration manager before sample preparation starts.
