The giant U.S.-owned gold and copper mine in eastern Indonesia where 28 workers died in a collapse says it has government approval to resume milling and underground mine operations.

Indonesia's government ordered the shutdown of those operations at the massive Grasberg mine in easternmost Papua province during investigation of the May 14 collapse of its Big Gossan underground training facility.

A statement from mine operator PT Freeport Indonesia said it received the official approval Tuesday from the Ministry of Energy and Mineral Resources. It pledges to take all corrective actions to reinforce its commitment to apply high safety standards.

The mine, owned by Phoenix, Arizona-based Freeport-McMoRan Copper & Gold Inc., produces around 220,000 tons of ore per day — 140,000 from its open mine and 80,000 from an underground mine.
