The price paid for gold purchased by Guyana Gold Board is not only dependent on the purity of the gold, but also on the prevailing price of gold on the London Bullion Marketing Authority (LBMA).
Notwithstanding this, the higher the purity the more per ounce you would be paid.
The purity of the gold is ascertained using the dry and water densities of the gold. Samples are also taken for testing from customer selling 10 ounces or more, where the cost of analyzing the sample is subsidized over 50% by Guyana Gold Board for testing done at Guyana Geology and Mines Commission and over 65% for analyses done at the Royal Canadian Mint. The payments are subsequently adjusted when results from such assay processes are returned to Guyana Gold Board, with the result that customers either receive additional payments where there are positive results or are required to reimburse excesses on their next sale, if the results are negative.
If Customers are not satisfied with the result of the Guyana Gold Board dry and water density test, they have the option to request that their gold is assayed, even though the gold is not of a sample quantity. It can firstly be sent to Guyana Geology and Mines Commission for testing for a small fee of four thousand, five hundred dollars ($4,500) and if they are still not satisfied when that result returns, then the sample can be sent to the Royal Canadian Mint for further testing after an additional fee of fifteen thousand dollars ($15,000) is paid. The results from Royal Canadian Mint would act as the final settlement, since analyses by that firm are internationally recognized.
