Bullion and Dore Testing

Bullion and dore bars represent pivotal assets in the precious metals market, serving as key indicators of value and purity in the global trade of gold and silver. Bullion bars, recognized for their high purity, play a crucial role in financial markets, investment portfolios, and central banks' reserves. Dore bars, often produced directly from mining operations, contain gold and silver in less refined forms, necessitating precise analysis to determine their true worth.

STEMart is specialized in the meticulous testing of these materials, employing cutting-edge technologies and methodologies to ensure accurate assessment. Our Bullion and Dore Testing Services are essential for stakeholders across the precious metals ecosystem, including miners, traders, and refineries, providing them with the confidence needed to navigate this complex market.
