PASS technology aims to rapidly dewater and treat tailings to accelerate reclamation and lower our environmental footprint at a lower cost Advancing execution, with regulatory approval received October 2017 Suncor pioneered TRO in 2010 (Tailings Reduction Operations)

Removal of MFT1 from tailings pond

Rapid dewatering of MFT1 with addition of flocculant2 Atmospheric drying of MFT1 Reclamation timeframe is extended Placement of MFT1 in thin layers for atmospheric drying takes time and is area limited due to drying process

Building on TRO with PASS (Permanent Aquatic Storage Structure)

Addition of coagulant3 to improve water quality

Placement of tailings below grade, suitable for lake bottom PASS does not result in new Reclamation timeframe is reduced Capping with aquatic cover (E.g. Demonstration Pit Lake) disturbed area

Anticipated benefits of PASS4  Faster reclamation  Lower cost  Community engagement  Demonstrated results

In 2018, PASS doubled tailings treatment capacity to 165% of total annual tailings production
