Yindongzi Ag and polymetallic deposit

The Yindongzi Ag and polymetallic deposit is located in Zhashui County on the southern slope of the Qinling Mountains in southern Shaanxi.

The ore district is 3 km long from east to west and 1.5~2 km wide from north to south. Its retained reserves are 2,257 tons with a silver grade of 107 g/t. This deposit was mined intensively in ancient times.

In the 1950s geological teams under the Ministry of Geology and Ministry of Metallurgical Industry conducted geological surveys and mineral prospecting. A geological and detailed exploration report was completed in 1981.

At present the Shaanxi Silver Mine has been established to carry out further prospecting work. As designed, 99,000 tons of ores are mined and dressed annually, and 140,000 tons of ore were produced in 1991.
