Gold and precious metals traceability
Every gram, traceable from the miner to the market
Minario records each purchase, smelt and sale of gold with the identity, assay and legal evidence that buyers, banks and authorities ask for.
The problem
Gold without proof of origin is losing its market
Much of the gold produced by artisanal and small-scale mining changes hands several times before it reaches a refinery, often recorded on paper or not at all. Buyers, refineries and banks increasingly require documented proof of where each lot came from and who handled it.
Fragmented records
Purchases, assays and payments live in notebooks, spreadsheets and messaging apps that cannot be audited.
Rising due diligence demands
Refineries, banks and export authorities ask for supplier identity, legal title and transaction evidence before they accept material.
Legitimate miners left out
Without a verifiable history, compliant producers struggle to reach formal markets and fair prices.
How Minario works
One continuous chain of custody
Each step inherits the evidence of the step before it, so the history of a gram is never rebuilt after the fact.
- 1
Register and qualify miners
Record identity, mining title or permit and the credentials each country requires.
- 2
Purchase with assay and identity verification
Weigh, assay and verify the seller before paying, with a price proposal calculated on the spot.
- 3
Smelt with inherited traceability
Every bar keeps the lineage of the purchases it came from, with loss (merma) recorded.
- 4
Sell with validated counterparties
Confirm the buyer's credentials and issue invoices tied to the traced material.
- 5
Report and audit
Produce the evidence file for each transaction and the reports authorities and buyers request.
