SANTIAGO, Sept 23 (Reuters) – Operations at the world’s largest copper ​mine, BHP’s (BHP.AX), opens new tab Escondida mine in Chile, ‌were suspended on Wednesday after a worker was killed in an accident, the firm said.

BHP ​said the worker had been killed ​while carrying out maintenance work. The ⁠union representing the site had previously told ​Reuters that the accident involved a front-end ​loader frequently used by the industry.

“All operational activities at the mine have been suspended,” BHP said ​in a statement, without giving a ​timeline for when they may restart.

Typically in Chile, ‌mines ⁠may only kick off activities after a fatal incident once inspectors verify that conditions are safe enough for a restart.

Escondida ​is located ​in Chile’s ⁠Atacama Desert. BHP operates the mine, while Rio Tinto (RIO.L) holds ​a 30% stake and Japan-based JECO ​Corp ⁠12.5%.

BHP had estimated the site would produce up to 1.28 million metric tons of ⁠the ​red metal this year.
