The search resumed Tuesday for a helicopter and two men missing in the northern Quebec territory of Nunavik since Friday.

Two men were on the helicopter, which is owned by Canadian Helicopters. Their names were not released but one is from Gander, is in his mid-30s and employed by the helicopter company.

The helicopter left Kangirsuk, a village on the west coast of Ungava Bay, to Kangirsujjuaq where it was expected to stop for fuel, but didn't arrive.

Capt. Mark Peebles, the public affairs officer for the search and rescue centre in Trenton, Ont., which is co-ordinating the search, said searchers are now focusing on an area last indicated by the chopper's satellite tracker.

"[It's] very challenging terrain over which they're flying and that they're looking through. It's very steep, very rugged terrain, lots of inlets," he said.

"There's a lot of snowy patches which you can understand makes it even more challenging when you're dealing with a helicopter that is painted white with a red stripe."

Peebles said the search area is about 50 kilometres by 110 kilometres.
