About US Oil Sands Inc.

US Oil Sands Inc. (formerly Earth Energy Resources Inc.) has developed an environmentally responsible process to extract hydrocarbons from solids. A bio-based solvent is used to rapidly liberate the hydrocarbons, reducing the mechanical energy and eliminating the pH control typically used to recover bitumen in surface mineable projects. The patent-pending process effectively extracts bitumen from water-wet and oil-wet oil sands. US Oil Sands has successfully developed the process at its facility in Grande Prairie, Alberta. Since inception, US Oil Sands has devoted its efforts to commercialize the water efficient and scalable process, which has no requirement for tailings ponds.

US Oil Sands, through its wholly owned Utah subsidiary, owns a 100% leasehold interest in 7,835 acres of Utah State land. US Oil Sands internally estimates, as of December 31, 2010, that in respect of this interest it has 177.8 MMbbl of bitumen which would be classified as Discovered Bitumen Initially-In-Place.

“Discovered Bitumen Initially-In-Place” is that quantity of bitumen that is estimated, as of a given date, to be contained in known accumulations prior to production. The recoverable portion of Discovered Bitumen Initially-In-Place includes production, reserves, and contingent resources; the remainder is unrecoverable. Further review of the Corporation’s resource evaluation procedures is required to assign the estimate of Discovered Bitumen Initially-In-Place to a more specific resource category. The resource estimate is a best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50 percent probability (P50) that the quantities actually recovered will equal or exceed the best estimate. The resource estimate has not been risked for chance of development (technical, economic, regulatory, market and facility, corporate commitment or political risks). There is no certainty that any portion of the resources will be developed or, if developed, there is no certainty as to the timing of such development or whether it will be commercially viable to produce any portion of the resources. A significant factor relevant to the resource estimate is the regulatory permitting process which is described in the Filing Statement.
