Freeport Grasberg Accident Leaves Worker Critically Injured

May 31 (Bloomberg) -- A worker was critically injured in an accident at Freeport-McMoRan Copper & Gold Inc.’s Grasberg complex in Indonesia today.

The incident occurred when wet material overflowed from an ore bin and covered a truck and its operator during maintenance activity at the Deep Ore Zone underground mine, unit PT Freeport Indonesia said in an e-mailed statement today. The injury wasn’t the result of a wall collapse, the company said in the statement.

The driver of the truck has been taken to hospital and is in critical condition, according to the statement. Daisy Primayanti, vice president of corporate communications at Freeport Indonesia, earlier said that the accident, which occurred at about 1 p.m. local time, was caused by a wall collapse.

The accident follows a tunnel collapse at the same facility on May 14 that killed 28 workers near the Big Gossan mine. Grasberg in Mimika, Papua province, about 3,120 kilometers (1,940 miles) east of Jakarta, includes underground and open-pit operations and is the world’s second-biggest by output, Freeport said in March.

Freeport restarted some operations at Grasberg’s open pit mine on May 28, the company said in a statement. It expects the mine to reach full production capacity of 140,000 metric tons of ore a day in three to four days, Rozik B. Soetjipto, president director at Freeport Indonesia, told reporters on May 29.

Freeport’s workers have refused to resume work until the company suspends officials believed to be responsible for the May 14 accident, Virgo Solossa, head of the Mimika branch of the All Indonesian Workers Union in the Chemical, Energy and Mining Sectors, said yesterday.
