CHANGING THE WAY 
BITUMEN IS EXTRACTED

CALGARY, ALBERTA September 16, 2013 – US Oil Sands Inc. (“US Oil Sands” or the ”Company”) (TSXV: USO), a company focused on oil sands exploration and production in the State of Utah, today announced the signing of a letter of intent (the “Letter of Intent”) with Blue Pacific Investments Group Ltd., Anchorage Capital Group, L.L.C. and Spitfire Ventures, LLC (the “Strategic Investors”). Under the terms of the Letter of Intent, US Oil Sands will issue up to $80 million of common shares of the Company at an issue price of $0.15 per common share in a private placement financing (the “Offering”). The issue price represents a 49% premium to the 20 day volume weighted average trading price of the Company’s common shares. Collectively, the Strategic Investors would hold approximately 63% of the issued and outstanding common shares of the Company after giving effect to the Offering. The Offering is expected to close on or about October 15, 2013 and is subject to the parties entering into definitive agreements and customary closing conditions, including due diligence as well as shareholder and TSX Venture Exchange approval. The Strategic Investors have an exclusivity period of forty five days within which to enter into definitive agreements in respect of the Offering. Management and directors of the Company unanimously support the transaction.

Upon closing, the Company’s board of directors (the “Board”) shall be reconstituted to include Serafino Iacono, Ronald Pantin, Rod Lewis, Kevin Ulrich, and Frank Giustra.  Verne Johnson, Cameron Todd and Ed Chwyl will remain in their roles as directors of the Company, with Verne Johnson remaining as Chairman of the Board. Departing from the Board will be Douglas Hunter, James Banister and Ken Stephenson.

“This transaction is a transformational one for our Company, as it fully funds Phase 1 of our PR Spring Project in Utah and bolsters our Board with a group that brings world-class expertise, financial backing and relationships,” said Cameron Todd, CEO of US Oil Sands. “Partnering with these strategic investors has greatly enhanced and fast-tracked the future prospects of our Company and increased our potential to export our proprietary, environmentally-responsible method of oil sands extraction into other global jurisdictions, including Canada and Latin America.”

Mr. Todd added: “On behalf of the entire Company, I wish to thank our retiring directors for the exceptional leadership and financial support they have provided since joining the Board over seven years ago.  They have played a key role in guiding the Company to its current level of success.”

The Company intends to use proceeds from the Offering to finalize the first phase of the commercial development of the PR Spring Project and to accelerate future production phases. The Company’s PR Spring Property spans 32,005 acres of land in Utah’s Uinta basin and, according to a resource report prepared by Sproule Unconventional Limited dated April 29, 2013 and effective as of February 28, 2013, contains an estimated 184.3 MMbbl of discovered petroleum (bitumen) initially-in-place.  For additional information, please refer to the Company’s Form 51-101F1 – Statement of Resources Data and Other Oil and Gas Information available on SEDAR at www.sedar.com.  

Together with funding the expenditures related to the closing of the Offering and general corporate purposes, proceeds raised in excess of those required to fund the PR Spring Project allow the Company to immediately initiate corporate development activities that may include the acquisition of or participation in other oil sands assets located outside the State of Utah. The Company intends to develop oil sand resources using its patented bio-solvent technology that achieves best-in-class environmental benchmarks and capital efficiencies.  

After giving effect to the Offering, the Company will have 846,164,397 common shares issued and outstanding.

Canaccord Genuity Corp., EAS Advisors, LLC through Merriman Capital, Inc., and Fiore Management & Advisory Corp. acted as financial advisors to US Oil Sands in connection with the Offering.
