Canadian centenarian

Some mines live longer than others, and the Dome underground mine in Timmins, Ontario, lived longer than most. The operator Porcupine Gold Mines, a subsidiary of Goldcorp, finally closed down the underground mines after 107 years of operation.

The discovery of the gold-rich Dome site was made all the way back in 1909, with production starting in 1910. Goldcorp confirmed that more than 67 million ounces of gold have been mined since then, and mine life had been extended as recently as July 2016. The surface operations will continue into the future, adding to the rich legacy of the Dome.
