A small commuter airliner registered to Northwestern Air Lease crashed near Forth Smith in Canada's remote Northwest Territories on Tuesday, killing some people on board.

The Australian mining giant said a plane bound for its Diavik mine and "carrying a number of our people" crashed "resulting in fatalities."

According to an aviation source, who asked not to be named as they were not authorized to speak to the media, one person survived.

The Joint Rescue Coordination Centre in Trenton, Ontario said contact with the plane was lost shortly after it took off at about 8:50 am local time from Fort Smith, which is 320 kilometers (200 miles) southwest of the regional capital Yellowknife.

Canadian Rangers on snowmobiles located the wreckage of the craft, while search and rescue technicians parachuted into the scene.

Northwestern Air, which operated the Jetstream twin turboprop airliner, said the charter flight crashed 1.1 kilometers (0.7 miles) from the end of the runway.

All flights from Fort Smith have been grounded until Wednesday.

Canada's Transportation Safety Board deployed a team to investigate the accident.

Rio Tinto chief executive Jakob Stausholm extended the firm's "deepest sympathy" to families, friends and loved ones of those affected.

"As a company, we are devastated by this news and offering our full support to our people and the community who are grieving today," he said.
