Operational Update

US Oil Sands’ core hole drilling program is proceeding as planned. Cameron Todd, CEO of US Oil Sands announced today that “With the completion of 119 out of a planned 145 core holes on our development property at PR Spring, Utah, the drilling program has already been a great success. Our results to date have met or exceeded expectations, and the program is on time and on budget. The company has discovered and confirmed the presence of significant bitumen resources on our development acreage and we intend to continue with final design of the PR Spring commercial bitumen mining project.”

The drilling program is on target for completion in late September. Laboratory assay and analysis of the recovered core is expected to be complete in the fourth quarter, and results will be used for final planning of the PR Spring Development Project as well as for completion of the company’s year end NI51-101 independent resource assessment.

US Oil Sands has recently added a third rig to the program with the capability of drilling to a deeper depth of 500 feet in order to fully assess US Oil Sands’ newly acquired 23,850 acre exploration land. US Oil Sands has also acquired an additional 320 acres of leasehold land contiguous to the 23,850 acres of exploration acreage. The company will seek to continue to expand its prospective bitumen land position as opportunities become available.

About US Oil Sands Inc.

US Oil Sands is engaged in the exploration and development of oil sands properties. The Company, through its wholly owned US subsidiary, has a 100% interest in bitumen leases covering 32,005 acres of land in Utah.

US Oil Sands plans to develop its oil sands properties using its patent-pending extraction process. This process is an efficient and environmentally responsible approach to oil sands development.

The process requires low energy input, recycles 95% of the water used and uses best practice mining methods to rapidly reclaim mined areas. US Oil Sands has received a permit to construct the PR Spring Bitumen Mining commercial project on its Utah property and is currently in the final design stage targeting first production in 2013.
