US Oil Sands Inc. Announces Approval of Patent Application by Canadian Intellectual Property Office

CALGARY, Sept. 6, 2012 /CNW/ - US Oil Sands Inc. ("US Oil Sands" or the "Company") (TSXV: USO), a company focused on oil sands exploration and production in Utah, today announced that the Canadian Intellectual Property Office has approved the Company's patent application relating to its bitumen extraction process.

"The approval of this patent by the Canadian Intellectual Property Office is an important final step in a process designed to solidify our Company's competitive advantage within the oil sands mining space," said Cameron Todd, CEO of US Oil Sands. "We believe our unique extraction methodology to be a true game changer for oil sands mining, as it not only expedites on-stream times using significantly lower amounts of capital, but also achieves best-in-class environmental results by eliminating the need for tailings ponds and dramatically reducing greenhouse gas emissions and energy consumption."

The Company completed the international filing of its patent application through World Intellectual Property Organization (WIPO) in October 2007 and continues to prosecute its US application, which remains pending with the United States Patent and Trademark Office.

US Oil Sands' 32,005 acres of bitumen leases in Utah's Uinta Basin make it the largest bitumen lease-holder of public lands in the US, and the Company's permitted PR Spring Project is expected to be the first commercial bitumen extraction project in the US. The extraction process is effective on both oil wet deposits such as found in the US and internationally, and water-wet deposits such as found in Canada's Athabasca region. Traditional extraction processes developed decades ago are effective on the water-wet oil sands found in Canada but are not at extracting bitumen from oil-wet deposits. Following completion of Phase 1 of the PR Spring Project the Company hopes to expand its proprietary process to include potential projects in Canada and elsewhere once lands have been secured.

The approval of the Canadian patent application is a key strategic advantage in Canada where no commercial process has yet been implemented that can operate without a tailings pond or with the small environmental footprint that US Oil Sands' process provides. In addition US Oil Sands' low capital cost allows the Company's extraction process to be deployed on a broad range of smaller deposits, previously deemed to be uneconomic.
