Located in northeast Alberta, our oil sands business is the bread and butter of our current operations and cornerstone for growth, with vast resources of 6.1 billion barrels of reserves and 17.8 billion barrels of contingent resources.*

Our oil sands operations recover bitumen through mining and in situ development and upgrade it into refinery feedstock, diesel fuel and by-products. What makes Suncor unique is the combination of our long-term growth strategy and our commitment to responsible development. While we continue to expand our operations, we work to minimize our environmental footprint and contribute to the well-being of the communities in which we operate.

We support our core oil sands business with conventional natural gas production which offsets energy consumption at our oil sands operations, and international and offshore assets that we anticipate will provide stable, low-cost cash flow to fund future oil sands growth.

In addition, we own and operate four refineries (with a combined capacity of 455,000 barrels per day) a lubricants plant, and a large network of retail businesses (1,500+) which connect our core oil sands business with a growing North American energy market.

Our investments in renewable wind energy and biofuel play a key part of Suncor's climate change action plan. In 2010, Suncor marked an industry milestone by becoming the first oil sands company to complete surface reclamation of a tailings pond, a key step in returning the site back to nature. The company also received approval to implement new tailings management technology — called TRO_TM — across its existing operations. We expect to invest more than $1 billion to implement the technology, potentially reducing tailings reclamation time by decades and speeding the return of oil sands mining sites to natural habitat.

* Reserves and contingent resource information presented herein is presented as Suncor’s working interest (operating and non-operating) before deduction of royalties, and without including any royalty interests of Suncor, and is as at Dec. 31, 2010. For more information please see Suncor’s current Annual Information Form dated March 3, 2011 available at www.sedar.com. Effective Dec. 31, 2010, Suncor’s best estimates of contingent resources for its mining and in situ operations in Alberta are set out in the table below.

1. Numbers in the above table are rounded to the nearest million barrels (MMbbls) and may not add due to rounding.
2. Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. There is no certainty that it will be commercially viable to produce any part of the contingent resources.
3. Best Estimate is considered to be the best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. The best estimate of potentially recoverable volumes is generally prepared independent of the risks associated with achieving commercial production.

Estimates of contingent resources have not been adjusted for risk based on the chance of development. There is no certainty as to the timing of such development. The economic viability of the contingent resources is dependent upon pricing and economic conditions. There is no certainty that all or any portion of the contingent resources will be commercially viable to produce. For movement of resources to reserves categories, all projects must have an economic depletion plan and may require, among other things: (i) additional delineation drilling and/or new technology for unrisked contingent resources; (ii) regulatory approvals; and (iii) company approvals to proceed with development. Significant factors which may change the contingent resource estimates include further delineation drilling, which could change the estimates either positively or negatively, and future technology improvements, which would positively affect the estimates. Also, we have assumed that all mining and some in situ contingent resources will be upgraded and sold as sweet crude oil (SCO). To the extent that these volumes are not upgraded, but rather sold as bitumen, contingent resources volumes reported would be lower for SCO and higher for bitumen and total contingent resource volumes would be higher because of the yield factor applied to bitumen volumes when upgraded into SCO.

The contingencies which currently prevent the classification of the contingent resources as reserves include: the need for higher density corehole drilling to improve the certainty of in situ resources; the need for further facility design and the associated uncertainty in development costs and timelines; the preparation of firm development plans and regulatory applications (including associated reservoir studies and delineation drilling); regulatory approvals; and corporate approvals to proceed with development.

The additional facility design work, development plans, reservoir studies and delineation drilling are often completed in the course of preparing the company’s application for regulatory approvals. Once all regulatory and corporate approvals are received and any other contingencies are removed, the resources may then be reclassified as reserves.
