In recent years, the isotope analysis method has been continuously improved. Furthermore, the new generation of multi collector inductively coupled plasma mass spectrometry (MC-ICP-MS) testing technology has been widely applied. Therefore, non-traditional isotopes (e.g., Cu, Sn, Ag isotopes) have shown good application prospects in tracing ancient metal products. The relevant progresses of these isotopes in the application research of ancient metal products in the past 20 years have been reviewed in this study and listed below, as well as their application prospects. (1) Due to the extensive and significant overlap of Cu, Sn and Ag isotopes between different deposits, these isotopes are difficult to trace the geological source of metal products as independent evidence. (2) Cu isotopes exhibit significant fractionation between primary and supergene ores and are considered to be reliable to trace the copper ore types. In addition, Ag isotopes also have the potential to constrain the silver ore types. (3) The combination of Cu-Sn-Ag isotopes with Pb isotopes and trace elements can be appilied to conduct comprehensive traceability research, using reasonable statistical methods. This method will be the development direction to trace the ancient metals products using non-traditional isotopes in the future.
