CHANGING THE WAY 
BITUMEN IS EXTRACTED

CALGARY, ALBERTA May 19, 2016 – US Oil Sands Inc. ("US Oil Sands" or the "Company") (TSXV: USO), an innovator of oil extraction technologies, today announced that it has filed its unaudited interim financial statements (“Interim Report”) for the three month period ended March 31, 2016 (“Q1 2016”) along with the management discussion and analysis (“MD&A”) of the financial results of US Oil Sands for such period.

The Company is also pleased to report that it held its Annual General and Special Meeting of Shareholders and that all resolutions were passed and director appointments made in accordance with the management information circular dated April 13, 2016.

As announced on April 18, 2016, the Company is proceeding with an equity rights offering for gross proceeds of up to C$12.8 million (the "Rights Offering") as detailed in the Company’s rights offering notice and rights offering circular.

A copy of the aforementioned documents are available 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.

“Following the planned slow-down of construction of the PR Spring Project (“Project”), our first quarter activities were largely directed at positioning the Project for an efficient recommencement of construction activities following the anticipated closing of our Rights Offering on or about May 31, 2016,” said Cameron Todd, CEO of US Oil Sands. “This AGM marks the fifth anniversary of US Oil Sands’ formation as a public company. It also marks a turning point in the Company’s history. With a successful financing we expect to complete our first project at PR Spring and produce first oil before year end. We are confident that the demonstration of the Company’s commercial technology and resource potential will support US Oil Sands’ expectation to emerge as an industry leader among the most efficient, lowest capital cost and most environmentally sustainable oil sands companies.”

PR SPRING PROJECT UPDATE

As announced on February 4, 2016, the Company initiated a reduction in the pace of field construction in order to preserve working capital. As at March 31, 2016, remaining costs to complete the Project, including commissioning and start-up expenses, are estimated at US$4.9 million (C$6.4 million) while working capital at March 31, 2016 is approximately US$1.3 million (C$1.7 million). To fund this shortfall along with future costs to optimize operations along with on-going corporate costs, the Company intends to use the proceeds from the Rights Offering.

Upon completion of the Rights Offering, the Company intends to resume full construction activities which consist primarily of on-site piping, instrumentation and electrical installation. Concurrent to and following mechanical completion, commissioning procedures will begin, followed by start-up, expected in Q4 2016.

RIGHTS OFFERING

As announced on April 18, 2016, the Company is currently conducting a financing by way of an equity rights offering. The Rights Offering is open to all shareholders of the Company as of the record date of April 25, 2016, on the basis of one right for each common share held. Each right will entitle the holder to subscribe for one common share of US Oil Sands upon payment of the subscription price of C$0.015 (US$0.012) per right.

Details of the financing are more fully described in the April 18, 2016 press release as well as set out in the rights offering notice and rights offering circular which are available under US Oil Sands’ profile at www.sedar.com and the Company’s website.

In connection with the Rights Offering, US Oil Sands has entered into a standby purchase agreement with the Company’s largest shareholder, ACMO S.à.r.l. (the "Standby Purchaser"), pursuant to which the Standby Purchaser has agreed to purchase all of the common shares that are not otherwise purchased by holders of the rights under the Rights Offering, subject to a maximum of US$7.5 million (C$9.6 million).

The rights are trading on the TSX Venture Exchange under the symbol USO.RT and will expire at 4:00 p.m. (Calgary time) on May 27, 2016 (the "Expiry Time"), after which time unexercised rights will be void and of no value. Shareholders who fully exercise their rights will be entitled to subscribe for additional common shares, if available as a result of unexercised rights prior to the Expiry Time, subject to certain limitations set out in the Company’s rights offering circular. The Company expects to close the Rights Offering on or about May 31, 2016.

Management has conducted a series of information meetings for shareholders at locations and times posted on the Company’s website and shareholders that were unable to attend any of these meetings are encouraged to review the webcast also available on the Company’s website. If any shareholder is interested in speaking to or meeting with the management of US Oil Sands, they are encouraged to contact the Company at their earliest convenience to coordinate suitable arrangements.

Annual general and Special Meeting of Shareholders

On May 18, 2016, US Oil Sands held its Annual General and Special Meeting of Shareholders. The Company is pleased to report that all resolutions were passed as presented in the Company’s Management Information Circular dated April 13, 2016. The Company’s presentation to shareholders can be viewed by visiting www.usoilsandsinc.com.

Management is pleased to report that it received very strong support from the Company’s shareholders for two important special resolutions. First, a special resolution authorized a consolidation of the issued and outstanding common shares on the basis of one (1) post-consolidation common share for up to every one hundred (100) pre-consolidation common shares. Following the Company’s April 2011 going-public transaction, subsequent equity financings, and taking into consideration the maximum number of common shares to be issued pursuant to the Rights Offering, warrants and other dilutive securities related to the Company’s long-term incentive plans, the Company will have 1.94 billion common shares outstanding which is considered to be an unsuitable capital structure for the Company. A consolidation of 100 to 1 would result in a post-consolidation amount of 19.4 million common shares.

Second, the Company requested its shareholders to approve a change in the name of the Company. The name “US Oil Sands Inc.” was chosen in 2011, after the acquisition of Earth Energy Resources Inc., to reflect the Company’s focus on developing oil sands properties in the State of Utah. Since that time, the Company has decided to expand its focus from solely Utah to other potential development areas, such as the Athabasca region of Alberta and other international opportunities.

Management and the Company’s board of directors believe that a name change is important to better reflect the focus and strategy of the Company on maximizing its use of innovative technologies in the energy industry and expanding to new geographic locations.

In the coming months, management will work with its board of directors to determine an appropriate consolidation ratio and to select a new name for the Company which better reflects its business focus and strategy.
