In April 2010 it was reported that antimony levels in water near the mine were as high as 11 parts per million, a thousand times those found in uncontaminated water. The antimony was found to be in the V oxidation state, believed to be the least dangerous aqueous form (antimony can have a I, III or

In 1981, reserves at the
Xikuangshan deposit amounted to 10,000,000 tonnes of ore that contained 2 to 3 percent antimony (200-300,000 tonnes of antimony), at the time geologists thought that there may be more in the area. By 2002 the estimated size of the deposit was 2,110,000 tonnes of pure

deposits. 464,000 tonnes of antimony were produced at the mine between 1892 and 1929. From 1949 to 1981, 172,000 tonnes of antimony were produced. In 1981 1,700 tonnes of ore was being mined each day which was between 2 and 3 percent pure antimony.
