A helicopter crash near Norman Wells, N.W.T., on Saturday morning killed a passenger on the helicopter, officials said.

The pilot and another passenger on board suffered undetermined injuries and were taken to the Norman Wells Health Centre before being transported to hospital in Yellowknife.

Great Slave Helicopters in Yellowknife issued a release late Saturday saying the helicopter belonged to its subsidiary, Sahtu Helicopters, and that the aircraft was carrying two workers from an exploration camp north of Norman Wells when it went down.

Another Sahtu helicopter flying in the vicinity reported the crash via satellite phone to the company's operations centre, the release said.

Police have not yet released the name of the passenger who was killed.

RCMP are investigating and say the Transportation Safety Board has been advised.

According to the company's website, Great Slave Helicopters is owned by Discovery Air and operates in close proximity to oil and gas activity in the Mackenzie Valley and mining operations at Lac de Gras.

The website says the company's fleet includes more than 75 aircraft and employs more than 200 people.
