CHANGING THE WAY 
BITUMEN IS EXTRACTED

CALGARY, ALBERTA August 15, 2013 – 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 it has filed its unaudited interim financial statements (“Interim Report”) for the three month period ended June 30, 2013 along with the management discussion and analysis (“MD&A”) of the financial results of US Oil Sands for such period.

A copy of the aforementioned documents may be found for viewing on the System for Electronic Document Analysis and Retrieval website at www.sedar.com as well as US Oil Sands’ website at www.usoilsandsinc.com.

SELECTED OPERATIONAL & FINANCIAL HIGHLIGHTS

• Continued progression of the 5,930 acre oil sands development project, including initiation of mine site clearing, water pumping installation, ore optimization, and testing and development of detailed mine and facilities engineering;

• Supply of water and raw road-building materials for Uintah County’s Seep Ridge Road Paving Project, a state-funded project that will serve the general public, ranchers, recreationalists, and the energy industry. Revenues therefrom will partially offset future capital costs associated with mine opening and water supply infrastructure;

• Continuation of outreach efforts to Utah-based government officials, business leaders, and communities; and

• Progressed PR Spring Project Joint Venture discussions with select parties.

“During the second quarter we were primarily focused on initiating site work as well as finalizing the engineering design of our PR Spring Project. We have also made good strides in our discussions with key parties engaged in our ongoing process of pursuing a JV financing agreement,” said Cameron Todd, CEO of US Oil Sands. “From an operational perspective, we anticipate commercial start-up of the initial phase of our project to commence in late 2014 however this of course is dependent on the timing of our financing.”

OPERATIONAL HIGHLIGHTS

During the second quarter the Company continued to work with its engineering consultants and equipment suppliers to complete final engineering design.  Mine planning activities continued to identify and plan expansion areas.

The Company also entered into an agreement to supply water and raw materials in Uintah County, Utah for a state-funded road building project. The 44 mile project will serve the general public, ranchers, recreationalists, and the energy industry. In relation thereto, the Company permitted and mobilized a man-camp to support field operations and acquired and installed pumping equipment to bring the production water well to operational status.

REGULATORY HIGHLIGHTS

On January 14, 2013, the Board of Directors of the Utah Division of Oil, Gas and Mining (“DOGM”) voted to support DOGM’s previous approval of the Company’s Notice of Intention to Commence Large Mining Operations at its PR Spring Project Area. The timeframe within which an appeal can be made has expired, and accordingly, DOGM’s issuance of the Company’s Notice of Intention to Commence Large Mining Operations at its PR Spring Project Area is final and fully in-force.

As of the date hereof, the November 1, 2012 decision by the Utah Department of Environmental Quality’s Water Quality Board to support the Company’s permit-by-rule as previously issued by the Division of Water Quality on March 4, 2008 is in appeal to the Utah Supreme Court by a Utah-based environmental organization. Appeals cannot introduce new evidence and are heard only on the basis of technicalities of law.

There are no other challenges or appeals against the Company or the regulatory agencies on any regulatory permits held by the Company in respect of its planned operations for the PR Spring Project Area.

OUTLOOK

For the remainder of 2013, the Company will continue to focus on the final engineering and procurement of equipment for site preparation and construction of the PR Spring Project Area. Management anticipates fabrication of the process extraction plant to commence in 2013, with final fabrication, field assembly and commercial start-up expected to occur in 2014. The timing of these plans is to a large degree dependent on when the Company raises the capital necessary to undertake the major expenditures. With the assistance of external corporate finance support, US Oil Sands continues the process of marketing and closing a joint venture financing.

Management intends to continue its pursuit of opportunities to add additional resource lands by assessing growth opportunities and furthering regulatory application efforts that ensure a ready inventory of future mineable assets for the Company.
