Abstract: As one of the world's largest gold producer and consumer, China faces a high dependence on imported gold resources, making intensified exploration and development efforts essential. The Eastern Tianshan region, where the Dongshan area of Xingxingxia is located, serves as a key mineral resource base in Xinjiang and exhibits significant potential for gold and polymetallic mineralization. Based on a mineral geological survey, this study focuses on the Dongshan area and integrates field investigation, trenching, and geochemical analysis. New discoveries include the Hongxingshan gold occurrence, the Dongqianluzi Lead Deposit, and 4 copper mineralized sites (Zhuanjing, Zhuanjing East, Dongshan, and Dongshan East). The findings suggest that the gold mineralization in the Dongshan area may be part of a porphyry-related system, likely representing an epithermal low-temperature hydrothermal type. The copper mineralization is inferred to be of a magmatic-hydrothermal vein type, while the newly identified lead mineralization may represent a distal expression of a molybdenum system. Overall, the Dongshan area of Xingxingxia shows significant exploration potential for gold, molybdenum, tungsten, tin, and copper, and may also host porphyry-type W-Sn and Mo deposits.
