How is Unrefined Gold assayed and verified?

Unrefined Gold typically runs at 85% – 93% Au, equivalent to a fineness of about 850 – 930. Natural and semi-refined gold varies lot to lot, which is exactly why the deal is settled on assay rather than on a headline number. Nobody serious pays a fixed price for an unverified purity.

We verify content using Fire assay, XRF. Fire assay remains the reference method for settlement because it measures the actual gold recovered from a representative sample; XRF gives a fast surface reading for cross-checking. On arrival in Dubai the buyer, or a mutually agreed assayer, confirms the content, and the final invoice is calculated from that figure.

This assay-first approach protects both sides. You never overpay for material that under-assays, and we are paid fairly for material that meets or exceeds expectations. It is the standard the UAE's refineries and bullion desks already work to.

Our unrefined originates in Cuyuni-Mazaruni and Issano. Guyana's gold sector is regulated by the Guyana Gold Board and the Guyana Geology and Mines Commission, which oversee declaration, export permits and the licensing of dealers and miners. That framework is the backbone of the documentation you receive.

Sourcing from a single, regulated origin country is a deliberate contrast to the anonymous, mixed-origin dore that fuels much of the negative news around the global gold trade. With Guyana Gold Mines, the chain of custody runs from a known region, through the Gold Board export procedure, to your assay in Dubai, and it is documented at every step.
