Unscheduled maintenance suspends production at the Muskeg River Mine

Calgary, Alberta - Shell Canada announced today that bitumen production at the Muskeg River Mine oil sands facility has been suspended while unscheduled maintenance work is undertaken on a large conveyor belt.

Early on February 24, 2006, a major tear was discovered in the conveyor belt that transports ore from the crushers in the mine to the bitumen extraction plant. Bitumen production at the mine has been shut down and will remain suspended until a full assessment can be completed and a course of action determined. Synthetic crude oil production at the Scotford Upgrader has been reduced pending the resumption of bitumen production from the mine. Further updates will be provided when more information becomes available.

The Muskeg River Mine is located about 75 kilometres north of Fort McMurray, Alberta. The Scotford Upgrader is located near Fort Saskatchewan, northeast of Edmonton. Together, these facilities make up the Athabasca Oil Sands Project, a joint venture among Shell Canada Limited (60 per cent), Chevron Canada Limited (20 per cent) and Western Oil Sands L.P. (20 per cent).
