Tigris Gold operates a state-of-the-art testing laboratory. Our testing methods are accredited to ISO/IEC 17025 standards. We specialize in traditional Fire Assay Method, also known as the Cupellation Method, to determine the concentration of Gold. Assaying monitors the quality of the metal throughout the refining process, determining the fineness of gold and silver. Tigris Gold’s assaying technology includes traditional fire assay as well as spectrometry. All material arriving at the refinery, whether doré or scrap, is melted and samples are taken. As a rule, each sample is divided into three parts, one for our customer, one for ourselves and one for arbitration, whenever deemed necessary.
