The Super Pit gold mine has started operating again along with 60 mines in the Kalgoorlie-Boulder region of Western Australia on 20 April after a 5.2 magnitude earthquake shook the region this week.
Most mine operators undertook emergency evacuations as a precautionary measure after the quake.
Western Australia Chamber of Minerals and Energy spokesman Matthew Payne said none of the mines reported significant structural damage and miners were able to resume work within hours of the event.
The Kalgoorlie Consolidated Gold Mines (KCGM)-operated Super Pit had been closed for the day shift but workers returned during the night, KCGM spokeswoman Holly Phillips said.
The 50-50 venture of Newmont Mining and Barrick Gold, Super Pit, Australia's biggest gold mine, produces about 850,000oz of gold a year.
