Utah Supreme Court Dismisses Challenge against US Oil Sands' PR Spring Project, Affirms Validity of the Company's Permit

CALGARY, June 25, 2014 /CNW/ - US Oil Sands Inc. ("US Oil Sands" or the "Company") (TSXV: USO), a company focused on oil sands exploration and production in Utah, announced today that the Utah Supreme Court (the "Court") has dismissed the only outstanding regulatory challenge made against the Company's PR Spring Project (the "Project"), located in Utah's Uintah and Grand Counties. In a unanimous decision, the Court found that the groundwater discharge permit-by-rule originally issued in 2008 by the Utah Division of Water Quality was correctly issued based on the conclusion that the Company's extraction process would have a "de-minimus" or negligible impact on ground water quality. Notably, the Company's process uses low impact, non-toxic substances without the use of tailings ponds and emits no free water or process fluids as it recycles its water and bio-solvent. Changes or enhancements made to the Project since that time were not judged to have any negative material impact on the original approval.

Further, the Court found that appellants challenging a permit decision must do so on a timely basis, thereby providing finality with respect to regulatory decisions and allowing permit holders to expeditiously proceed with their projects.

Cameron Todd, CEO of US Oil Sands commented, "We are pleased that the Court clearly supports the validity of permits granted to the Company's PR Spring Project. US Oil Sands has continually demonstrated its commitment to environmentally responsible energy development and expects to showcase its breakthrough extraction technology when the Project begins producing next year."
