International Enexco Limited: Drilling Update at Mann Lake Uranium Project Athabasca Basin, Saskatchewan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 14, 2010) - International Enexco Ltd. (TSX VENTURE:IEC) (the "Company" or "Enexco") reported today an update on drilling operations at International Enexco's Mann Lake uranium project located in the eastern portion of the Athabasca Basin, Saskatchewan.

The Mann Lake project is a uranium exploration joint venture between International Enexco Ltd. (30%), Cameco Corporation (52.5%), and AREVA Resources Canada Ltd. (17.5%). The project is located approximately 25 km southwest of Cameco's McArthur River uranium deposit, the world's largest and highest grade uranium mine, and approximately 20 km northeast of Cameco's Millennium uranium deposit.

The 2010 drilling program was carried out by Cameco, operator of the project, from mid-February through late-March, during the winter season, and from early-June through late-July, in the summer season. A total of 2,387 m were drilled in 4 diamond drill holes located to test geochemical and structural anomalies identified from previous drilling and exploration surveys along the C conductor trend that extends north-south for approximately 5,000 m through the central portion of the Mann Lake property. Of particular interest was a geochemical anomaly and large unconformity offset west of the previously drilled high-grade intersections discovered at Mann Lake in 2006 (7.12% U3O8 over 0.25 m and 5.53% U3O8 over 0.4 m) within the basement, 12 m beneath the unconformity surface (see Enexco June 20, 2006 news release).

Two holes were collared during the winter season. The first hole, MN-028, was designed to test geophysical anomalies (resistivity and gravity lows) located in the center of Spring Lake. The hole encountered unusually thick overburden, apparently coincidental with the gravity low anomaly and possibly related to a NNE-striking, east-dipping, deeply-rooted structure intersected in drill hole MN-023, located approximately 106 m to the east. Due to deteriorating ice conditions, hole MN-028 was abandoned at a depth of 340 m in well altered and structurally disrupted sandstone.

The second winter season hole, MN-029, was designed to test the northern segment of the western conductor axis. The hole was collared at the location of hole MN-026 which tested the eastern conductor axis in 2009 and intersected weak but thick geochemical anomalies in the lower sandstone. Hole MN-029 penetrated a well altered and structured sandstone column to a depth of 532 m, at which depth the drill rods became stuck and the winter drill program was halted. Attempts to rescue the hole during the summer drill program were unsuccessful.

During the summer season, MN-030 was drilled to a depth of 730 m to test the western conductor along the C trend north of Spring Lake. Indicative alteration and structure were encountered in the upper and lower portions of the sandstone column followed by intense clay alteration with coincident, sporadic, weak elevated radioactivity in 2.7 m of basement at the unconformity. No significant post-Athabasca faulting was encountered in the basement, however a section of moderate to strongly graphitic pelite was intersected approximately 90m below the unconformity.

The last hole of the current program, MN-031, was also designed to test the western conductor along the C trend, and was completed to a depth of 785 m. The hole intersected indicative structure and alteration in the sandstone section above the unconformity and strongly graphitic rock units in the basement below. Strong faulting encountered in the basal sandstone is interpreted to be related to the targeted western conductor axis of the main "C" trend. Weakly elevated radioactivity was encountered at the unconformity contact and approximately 60 m into the basement.

A large number of targets remain to be tested on the Mann Lake Property. Enexco anticipates exploration and drilling programs will be continued at Mann Lake. Future updates will be issued by Enexco as they are received from Cameco.
