Powertech Announces Significant Increases in Inferred Uranium Resources at Dewey-Burdock and Centennial Projects

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 22, 2009) - Powertech Uranium Corp. ("Powertech" or the "Company") (TSX:PWE)(FRANKFURT:P8A) is pleased to announce a 42% increase in inferred uranium resources at its Dewey-Burdock Project in Custer and Fall River Counties, South Dakota and an 18% increase in inferred uranium resources at its Centennial Project in Weld County, Colorado.

In the Company's original technical report for the Dewey-Burdock Project, it identified 7.6 million pounds of inferred uranium resources within the project, contained in 1,807,000 tons, averaging 0.21% U308. As a result of property acquisitions and continued evaluation of the historic close-spaced drilling undertaken by the Tennessee Valley Authority within the project boundaries, Powertech has revised total inferred resources within the Dewey-Burdock Project upward to 10.8 million pounds, contained in 2,992,836 tons, averaging 0.182% U308.

Powertech's original Centennial Project technical report identified 9.7 million pounds of inferred uranium resources, contained in 5,175,800 tons, averaging 0.094% within the project. This resource estimate was calculated at mineralized cutoffs of 0.02% U308, with a cutoff grade thickness ("GT") factor of 0.2. Through acquisition of additional property and the continued evaluation of historic close-spaced drilling within the project boundaries conducted by Rocky Mountain Energy Company, Powertech has revised the total inferred resources within the Centennial Project upward to 11.5 million pounds. These calculations used a 0.2 GT cutoff, as described above, and resulted in the delineation of 6,115,193 tons at the same average grade of 0.094% U308. Applying a higher 0.5 GT cutoff to the same deposits, Powertech measured 7.7 million pounds of inferred resources, contained in 3,369,455 tons, averaging 0.114% U308.

Updated technical reports entitled "Updated Technical Report on the Dewey-Burdock Uranium Project Custer and Fall River Counties South Dakota", dated June 17, 2009, and "Updated Technical Report on the Centennial Uranium Project, Weld County, Colorado", dated June 15, 2009 (the "Technical Reports"), were prepared for the Company by James Bonner, a Certified Professional Geologist (Wyoming PG No. 906) and the Vice-President of Exploration for Powertech. Complete versions of the Technical Reports will be filed on SEDAR at www.sedar.com.
