Rockfall in May that trapped 9 miners has company reassessing practices in area prone to tremors
Canadian miner Iamgold Corp. has cut its gold production forecast for the year, after a probe of what it calls a “localized seismic event” in a Quebec mine.
On May 26, the company halted production at its Westwood mine, one of its newest mines, after a rockfall that trapped nine miners for about 18 hours.
The Westwood mine, which is located near the Cadillac fault, experience two seismic events, with magnitudes of 1.2 and 1.7.
The Westwood event will “have a more significant impact on 2015 production than originally indicated,” Iamgold said a statement on Monday.
CEO Steve Letwin said mining companies working in the region ‘know that this district is prone to seismic activity and we are taking the necessary measures to keep our excellent safety record intact.”
