Suncor Base Mine Extension Project

Suncor Energy Inc. (Proponent) is proposing to develop the Base Mine Extension Project (the Project) to sustain the supply of bitumen to the existing upgraders at Suncor's Oil Sands Base Plant operation (Base Plant). The Project includes an open pit mining operation and associated infrastructure that is required to supply oil sands to new bitumen froth production facilities and deliver bitumen froth by pipeline to the existing Base Plant facilities where further processing occurs, including upgrading into various product blends for market. The Project is located adjacent to existing Base Plant operations approximately three kilometres north of Fort McMurray, Alberta, within the Regional Municipality of Wood Buffalo. Project construction is expected to start in 2026 and the footprint is anticipated to be approximately 20 000 hectares.
