Doré net-value calculator.

The payable rate is the refinery's truth serum. It prices four things at once: verified purity (your XRF reading, confirmed by fire assay), the silver and base-metal content that must be separated, the refinery's treatment charges, and how much the refinery trusts the corridor the metal arrived through.

Sellers improve their payable rate by improving what the refinery sees: independent assay at origin, complete export documentation, and delivery through recognized logistics. A documented lot from a known corridor negotiates from strength; an anonymous lot negotiates from hope.

Read the full mechanics in Doré payable rates explained, or verify your own material through a structured trial lift.

How to use the estimator: enter gross bar weight in kilograms, the XRF purity from your screening report (our corridor benchmark is 95.89% Au), the payable rate your refinery or buyer is offering, and — if you want a scenario other than today's — override the live XAU/USD spot. The estimator returns fine gold content, payable ounces, and an estimated net value. It is an indicative desk tool, not a settlement engine: final numbers always follow the destination refinery's fire assay and the written instrument terms agreed between verified counterparties.
