From Mine to Vault: The Journey of a Congo Gold Bar

You want two things: verified metal and smooth delivery. This page shows how a bar moves from licensed miners in the DRC to your vault, with the documents you need at each step.


The short version

  • Buy from a licensed exporter that gives you a written quote with every fee.
  • Keep the chain of custody intact from mine to export to intake.
  • Receive an assay card or report, a serial list for cast bars, and a full export pack.
  • Ship insured and tracked, then store in a depository or secure safe.
