The three miners who are trapped underground at Red Chris mine in British Columbia are behind a wall of debris that is between 20 and 30 metres long and seven to eight metres high, the mine operator says.
A remote-controlled scoop transported from a nearby mine is being used to begin removing debris to restore access, according to a statement from Newmont Corp., the majority owner of the Red Chris copper and gold mine in Dease Lake, B.C.
