Chen, formerly head of the Zijinshan gold and copper mines in Fujian province, was held as a suspect in relation to “the major pollution incident,” according to a statement to Hong Kong’s stock exchange today.
China’s biggest gold producer was forced to shut its copper plant at Zijinshan this month after acid-laced waste spilled from the site, poisoning a river. The company said yesterday that it had also agreed to limit production at a gold mine in the area to reduce environmental risks.
Zijin rose 3 percent to close at HK$5.14 in Hong Kong today, before the statement. The stock gained 2.5 percent to 5.86 yuan in Shanghai.
The company said it received a notice today saying that Chen had been detained.
