Mystery surrounds tons of dead fish in a river near a tin mine

AUTHORITIES in southwest China are investigating what killed more than 90,000 kilograms of fish in fish farms along a river downstream from a collapsed dam at a tin mine owned by Zijin Mining Group, China's biggest gold miner.

Environment officials in Wuzhou County, Guangxi Zhuang Autonomous Region, said they received the first report of dead fish in Huanghua River on September 22, one day after the dam broke in a landslide triggered by torrential rains from Tyhoon Fanapi.

Initial tests showed the river's water quality was within the safety levels for heavy metal, acidity and alkalinity and dissolved oxygen, the People's Daily reported today.

Another test conducted in neighboring Guangdong Province also showed the water quality of Qianpai River and Huanghua River, both downstream from the dam, was within safety levels.

The tin mine has been temporarily closed due to the incident. The mine obtained its production license from Guangdong authorities in August and was in trial operation when the disaster happened.
