Centennial Project - Drilling Update

 POWERTECH URANIUM CORP. ("Powertech" or the "Company") is pleased to announce that it has completed field activities and has received chemical analyses from its drilling and coring program on the Centennial Project in Weld County, Colorado. This program was completed in the fall of 2007 and was authorized under a permit from the Colorado Department of Natural Resources' Division of Reclamation Mining and Safety (DRMS).

Powertech completed 20 rotary drill holes within six historic uranium resource areas as were described in its NI 43-101 technical report; Report on the Centennial Project, Weld County, Colorado. This drilling, which totalled 6,350 feet, confirmed the presence and nature of the uranium deposits identified by Rocky Mountain Energy Company in the late 1970's and early 1980's. In addition, 318 feet of core was taken from six of the drill holes - one in each resource area. Core samples were taken to provide data on the chemical and physical nature of the mineralized sands of the Fox Hills Formation. This drilling/coring program was also designed to coordinate with planned hydrologic pumping tests in the resource areas. Several of the drill holes were completed either as pumping wells or observation wells for these hydrologic tests. The pumping tests are scheduled for completion by year end 2007.

All rotary drill holes encountered significant uranium minerlization and were used to establish locations for the six core holes. Mineralized intercepts within these six core holes, as indicated by down-hole radiometric logging include:
------------------------------------------------
Hole No.   Thickness   Grade      Depth
------------------------------------------------
IN-1C      29 ft       0.036%     eU3O8 456 feet
IN-2C      16.5 ft     0.096%     eU3O8 475 feet
CN-3C      21.5 ft     0.083%     eU3O8 121 feet
CN-4C       9.0 ft     0.15%      eU3O8  98 feet
CN-5C      24.0 ft     0.103%     eU3O8  98 feet
CN-6C       4.0 ft     0.09%      eU3O8  98 feet
------------------------------------------------
Analytical results have been received on five core holes from the Centennial Project. These assays included both gamma eU3O8 values and chemical U3O8 values for 1-foot samples throughout the mineralized zones. A comparison of these values provides valuable information on the equilibrium state of the uranium deposits. As shown below, one core hole (IN-2C) was in equilibrium - exhibiting no chemical enrichment or depletion. The other four core holes exhibited significant chemical enrichment of uranium (ranging from 30% - 90% enrichment). This high degree of enrichment indicates the uranium mineralization is highly mobile - an extremely favorable factor for proposed In-Situ Recovery (ISR) mining operations.

Hole No.  Gamma eU3O8               GT    Chemical U3O8            GT
-----------------------------------------------------------------------
IN-1C     30.0 ft. of 0.038% eU3O8  1.14  29.0 ft of 0.057% U3O8   1.65
IN-2C     16.0 ft. of 0.126% eU3O8  2.02  16.0 ft of 0.125% U3O8   2.00
CN-3C     20.0 ft. of 0.082% eU3O8  1.64  18.0 ft of 0.119% U3O8   2.14
CN-5C     21.0 ft. of 0.087% eU3O8  1.83  21.0 ft of 0.168% U3O8   3.53
CN-6C      4.0 ft. of 0.094% eU3O8  0.38   4.0 ft of 0.123% U3O8   0.49

In addition to chemical assays, these cores were also used to obtain valuable information regarding physical parameters of the Fox Hills host sands. One of the most important geotechnical considerations in ISR mining operations is the permeability of the mineralized sands. High permeability allows oxidizing solutions to readily move through the sands and contact uranium mineralization. Analytical results of mineralized core samples showed exceptionally high horizontal permeability of the mineralized sands - ranging from 800 to 1400 millidarcies. Permeability of the confining clay units, above and below the mineralized sands, was also analyzed. These units showed extremely low vertical permeability - ranging from 8.0 x 10(-8) to 5.0 x 10(-9) centimeters per second. Confining units composed of tight, low-permeability clay units are ideal for maintaining control of solutions during the proposed ISR mining operations.

The results of the analyses from the drilling and coring program, combined with hydrologic information to be gathered in the planned pumping tests, will be incorporated into bench-scale metallurgical testing to estimate ISR mining efficiencies for the Centennial deposits. Results of this testing should be complete by the spring of 2008 and will provide valuable technical input in support of the Company's operational permitting effort. Limited additional drilling is planned for 2008 within the identified resource areas at Centennial due to the high density of the historic drilling and the Company's confidence in historical drill hole control at the project. Future drilling at Centennial will focus on expansion of the already defined resources.

Richard F. Clement Jr., President and CEO, states "The drilling and coring program at Centennial continues to confirm the historical exploration data on the project. The results of this program have also demonstrated that the project is favourable for development of ISR operations. We are extremely pleased with the results of the program and will continue to push forward diligently in our permitting efforts".
