A rooftop fire at the PotashCorp Cory potash mine west of the city kept crews busy last night.

The call came in just before 10 p.m. CST.

The first crews on scene saw smoke and flame coming from a third floor roof. The potash company's fire fighters were already pouring water onto the building when the city crews arrived.

The smoke and flames were coming from between the roof smoke stack and the outside of the building. It appeared that the fire started above the scrubber room, which is part of the potash drying process where the heat and steam from the drying is vented through a large exhaust.

It took less than an hour to get the fire under control. There were no injuries, and no estimate on damages.
