US Oil Sands Announces $9 Million Private Placement Financing and Opens Data Room for Partner Participation

CALGARY, ALBERTA May 2, 2012 - US Oil Sands Inc. (TSX-V:USO) (the “Company”) today announced that it has entered into an agreement with Dundee Securities Ltd., on behalf of a syndicate including FirstEnergy Capital Corp. (the “Agents”) under which the Agents have agreed to offer for sale, on a best efforts private placement basis, up to 50,000,000 units (the “Units”) at a price of $0.18 per Unit for gross proceeds of $9,000,000 (the “Offering”).

Each Unit shall consist of one common share (“Share”) of the Company and one full common share purchase warrant (“Warrant”).  Each Warrant shall entitle the holder thereof to acquire one Share of the Company at a price of $0.26 for a period of 24 months following the closing date.

In addition, the Company has granted the Agents an over-allotment option (the “Option”) to sell up to an additional 15% of the Units sold pursuant to the Offering, exercisable at any time prior to 48 hours before the closing date of the Offering.

The closing date of the Offering is scheduled on or about May 17, 2012.  All securities issued will be subject to a four month hold period. The Offering is subject to a number of conditions, including, without limitation, receipt of all regulatory approvals.

The Company intends to use the net proceeds of the Offering to initiate construction of its PR Spring Commercial Bitumen Mining Project and for general corporate purposes.

“These initial funds will allow us to initiate construction on our PR Spring project, the first commercial oil sands extraction project in the US.”, said Cameron Todd, Chief Executive Officer of US Oil Sands. “We are currently planning to issue work orders next month for fabrication of long lead equipment. Mine preparation work will begin this summer, while project skids will be fabricated beginning in Q4 this year. Installation and field construction will take place in mid-2013. The project is on-target for completion and start-up in Q4, 2013.”

US Oil Sands uses skid-mounted modular construction methods to build 2000 barrel per day phases which allow for rapid construction and sequential build-up of additional phases. The initial 2000 barrels per day project at PR Spring is expected to cost $30 million to construct, while subsequent phases are expected to be added at a cost of $25 million.

US Oil Sands also announced that it has invited a number of potential partners to consider participation in its PR Spring project. The Company has opened a data room to allow potential partners to evaluate the opportunity, and expects to use the proceeds of a possible transaction to complete the construction of the first phase of the project and initiate work on design and permitting for potential  future expansions and new mine applications on the Company’s existing resource base.
