The open-pit copper and gold mine in B.C.'s far north, where three miners are trapped underground, is slated to transition to a new form of mining soon, in a project the provincial government says it intends to fast-track.

A rescue operation is underway at the Red Chris gold and copper mine to reach the trapped miners, who were safe in a sealed chamber underground, according to officials.

The drillers were brought to the surface around 10:40 last night.The men had been sheltering in a refuge chamber with access to food, water and air.Specialized equipment was used to clear the tunnel after two ground collapses.

Rescue efforts continue on Thursday after a fall of ground incident on Tuesday morning that left three contractors stranded.

Mining major Newmont is continuing rescue efforts to reach three workers trapped underground at the Red Chris mine in British Columbia, following two fall-of-ground incidents that have blocked access with as much as 30 m of rock and debris.

According to a Thursday evening update from Newmont Corp., which operates the Red Chris mine, the debris blocking access to the underground area is estimated to be 20 to 30 metres long and 7 to 8 metres high. There is a gap between the top of the pile and the roof of the mine, allowing drone access.

Bernard Wessels, global safety head for Newmont Corp., says natural air is flowing to three workers trapped underground at the Red Chris mine site about 500 kilometres northwest of Terrace, B.C. He says there appears to be a stable route to them behind the rockfall that cut them off,
