HONG KONG PT Freeport Indonesia has restarted some operations at its Grasberg copper mine after receiving Indonesian government approval.
"We have started operation at our open pit and mill yesterday and are slowly ramping up," Daisy Primayanti, vice president of corporate communications, said in a June 23 e-mail to AMM sister publication Metal Bulletin. "As far as our underground operation is concerned, we cant give any indication of time at this point as investigations by both the government special team and our internal team are ongoing."
Phoenix-based Freeport-McMoRan Copper & Gold Inc.s Indonesian subsidiary declared force majeure on concentrate shipments from its Grasberg Mine after a tunnel collapsed in an underground training facility May 14, killing 28 workers (amm.com, June 12). A truck driver also was killed June 1 in a separate accident.
Grasberg, one of the worlds largest copper-gold mines, normally produces about 220,000 tonnes of ore per day, with about 140,000 tonnes from the open pit and 80,000 tonnes from underground mining operations, local media and analysts have said. It employs more than 24,000 workers.
