The bodies of two millworkers have been found at the burned remains of a B.C. sawmill where an explosion took place late Friday.

Officials did not identify the bodies of either person, but two missing men from the mill were identified earlier as Carl Charlie and Robert Luggi.

Nineteen people were injured in the fire and subsequent explosion at the Babine Forest Products mill in a remote community near Burns Lake, B.C.

RCMP said the site remains "extremely unsafe" and fires continue to pop up, hampering an investigation.

John Wiebe was working the night of the fire and said he and other workers smelled something smoldering, several hours before the explosion occurred.

"A big wall of fire, just boom!" Wiebe told CTV British Columbia. "The next thing we know we are picking ourselves up off the wall."

He said they tried to make their way to an exit but the roof had caved in. They managed to escape by going down to another floor.

Wiebe suffered second and third-degree burns and said he knew both of the missing men.

Charlie's parents lit a candle for their missing son at a local community centre on Sunday evening. The father of two, described by a cousin as "happy go-lucky," had worked at the mill for more than 20 years.

Severe injuries

Investigators still haven't determined what caused the fiery blast. Workers at the mill, however, reported smelling gas earlier in the day.

Meanwhile, the 19 people hurt in the blast are spread out around B.C. and Alberta suffering from various types of injuries, mainly burns.

Three patients were released from a hospital in Prince George on Sunday. Another three were sent to Vancouver General Hospital, which will receive one more person Monday.

Two of the injured were sent to an Edmonton hospital, while the rest of the injured are being treated at various hospital facilities in British Columbia.

Of the 19 injured, at least four were in critical condition. An immediate update on their conditions was not available on Monday morning.

The mayor of Burns Lake said residents are currently concerned about the health of their loved ones, but financial worries are also on the horizon.

Babine Forest Products was a major employer in the small B.C. town of 3,500 and many are concerned that the jobs lost at the mill may not be recovered.

"It's devastating for those workers but I want to assure everyone that we are working our best to work on transition funding," Strimbold told CTV's Canada AM in a phone interview on Monday.

The mill is located about 220 kilometres west of Prince George and employs about 250 people. The facility is jointly owned by Burns Lake Native Development Corp. and Hampton Affiliates, a forest-products company based in Portland, Oregon.

Damage estimates on the facility have been coming in as high as $100 million, dampening hopes that the bill will be rebuilt.

Strimbold said it will likely range from $25 to $100 million to build a new mill.

"That's why we need to ensure we have a timber supply in our area so that a company can make that investment back into our community," he said.

B.C. Premier Christy Clark has vowed support for the tiny B.C. community, but it's unclear what form of support she means.

"We are going to have to work together to make sure that this community gets through this," she told a crowd of grief-stricken residents on Sunday.

Meanwhile, investigators are still speaking with workers who were in the plant at the time of the blast. The RCMP has said the investigation will take some time.
