CHANGING THE WAY 
BITUMEN IS EXTRACTED

US Oil Sands Inc. Announces State Finding Supports PR Spring Permit

CALGARY, ALBERTA August 29, 2012 – 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 Utah State Administrative Law Judge Sandra K. Allen issued her findings and recommended order on August 28, 2012 that supports the Company’s permit-by-rule for its PR Spring Oil Sands Project. 

In her finding Judge Allen determined that, “Substantial evidence in the record supports a finding that shallow groundwater has not been located and may be assumed absent in the project area.” The judge further found that, “US Oil Sands proposed operation does not present a greater than de minimis risk of affecting the quality of ground water.”

Judge Allen’s recommended order denies the relief sought by the intervener in its Request for Agency Action and is now expected to be considered by the Utah Department of Environmental Quality’s Water Quality Board, which is authorized to rule in the matter.

“Judge Allen’s finding further substantiates the outstanding environmental attributes of US Oil Sands’ extraction process which uses only a non-toxic bio-solvent derived from citrus to remove oil from the sands,” said Cameron Todd, CEO of US Oil Sands. “We believe this process, which requires no tailings ponds, enables the PR Spring Project to possess one of the lowest environmental footprints in its class. This finding further advances our operational plan for the PR Spring Project and we continue to remain on-target for start-up in Q4, 2013.”

US Oil Sands has 100% interest in bitumen leases in Utah’s Uinta Basin on which the Company plans to develop an oil sands mining extraction project. In 2008 the Company received Utah state approval for a ground water discharge permit-by-rule, and in 2009, a large mine permit for the development of an oil sands mining project on the PR Spring Development lease. In 2011, subsequent to the Company’s request for modification of the permitted project, a challenge to the modification and the original permit was filed by a Utah-based environmental organization. The intervener claimed that the project would have a detrimental impact on groundwater in the area. A hearing to adjudicate this challenge was heard on May 16-17, 2012 by Sandra K. Allen, an administrative law judge appointed through the Utah Department of Environmental Quality.
