The Lengshuikeng Silver Mine is located in Guixi County, Jiangxi Province.The mine is 7 km long from north to south and 5 km wide from east to west, covering an area of 35km2.

The retained reserves are 3,336 tons with a silver grade of 146.21 g/t. The discovery and exploration has experienced several partly overlapped stages: exploited as a "vein-like and banded" Pb-Zn deposit, porphyry Pb-Zn deposit, porphyry Ag deposit, and stratabound diplogenic silver and gold deposit. After 20 years of exploration, this large Ag deposit was eventually proved. The first mine, the Yinluling Silver Mine, in the Lengshuikeng ore district was built in 1990 and went into operation in 1992 with a daily ore mining and dressing capacity of 500 tons and an annual silver output of 22.96 tons.
