We use the Fire Assay Method, also known as the Cupellation Method to determine the concentration of Gold. We provide comprehensive assaying service to our clients dealing only with reputable and government registered assayers. A small sample of material has its precious metals chemically separated from the impurities and base metals contained in the material.
The precious metals remaining are then compared to the original starting weight of the sample to determine the composition percentage. The Fire Assay analysis has an accuracy of 1 part in 10,000. We deliver assay results within 24 hours or 48 hours in the case of a disputed result.
