Wednesday, September 29, 2010 Blue Sky Extends Uranium Mineralization in Phase II drilling at ANIT -------------------------------------------------------------------------------- Blue Sky Uranium Corp. (TSX-V: BSK, WKN: AOMKXP) is pleased to announce complete results from Phase II aircore drilling at its ANIT project in Rio Negro Province, Argentina. The Phase II program, totaling 2,581m in 107 holes, was designed to test for extensions of the ANIT West and Central zones as well as to provide a preliminary evaluation of ANIT East, radon gas anomalies and buried targets (Map 1). This work, combined with the Phase I drilling (May 18th and June 16th 2010 News Releases) brings the total drilling to date on the ANIT area to 5,044m in 204 holes. Results from the Phase II drilling on the ANIT West and Central zones are presented in Table 1 below. Highlights include ANIT West hole AN174 that averaged 4m at 0.078% U3O8 and 0.107% V2O5, and ANIT Central hole AN168 that averaged 7m at 0.037% U3O8 and 0.028% V2O5. This additional drilling in the main ANIT area provides further definition to strongly mineralized and thicker portions of the mineralized paleochannel at ANIT. The advantage of the ANIT deposit style is the potential low cost of mining at surface and the potential to up-grade the deposit by simple physical separation of the carnotite uranium mineralization from the sand and gravel host. Since the mineralization is hosted by the fine sand component and non-mineralized gravel comprises a significant percentage by weight, removal of the coarse material by simple screening process could significantly increase the grade of the material prior to processing. This can have very positive effects on processing costs and also may significantly lower the economic cut off grade. Blue Sky has recently commenced detailed sampling of the ANIT West and Central areas using a large excavator capable of reaching to 6m depth. The excavator pits will be hand sampled by Blue Sky technical staff, giving excellent geological control and accurate sample collection. At present the majority of mineralization discovered is in the 0-6m depth range. The Company has also retained Independent Metallurgical Operations PTY LTD of Australia (IMO) to carry out beneficiation testing and basic metallurgical testing of the ANIT uranium-vanadium deposit.

Away from the main paleochannel large areas of lower grade, but potentially economic mineralization, have been discovered at ANIT East as well as 200m north and 400m south of the ANIT Central zone (See Table 2). Of 8 regional radon targets drilled 7 had no significant results, however, 1.65 km north of ANIT hole AN124 cut 1m at 0.017% U3O8 and 0.080% V2O5 at 8-9m below cover. Table 2.

In the Phase II aircore drilling the addition of a second cyclone and careful attention to dust suppression resulted in much improved recoveries compared with Phase I drilling. Blue Sky considers aircore drilling a cost effective and fast method of locating mineralization, but not an optimal sampling method as the quantitative measurement of very fine clay size carnotite uranium mineralization (hosted unbound in dry loose sands and gravels) with conventional drilling methods has proved difficult as experienced by Blue Sky's team and other companies working on similar deposits in Africa and Western Australia. However, the benefit of the mineralization being located in the fine lose material and not bound within sand and gravel pebbles is in the potential to upgrade the mineralization as described on page one of this news release.

In contrast, Blue Sky's "ANIT" is hosted in sand and gravel. Analyses of samples reported herein were performed by Alex Stewart Assayers, in Mendoza, Argentina, an internationally recognized analytical services provider, by means of Inductively Coupled Plasma Mass Spectrometry following a four acid digestion (ICP-AR). Blank, duplicate, and standard samples were inserted into the sample sequence sent to the lab for quality assurance/quality control (QA/QC) purposes. In total, 144 quality control samples (15 % of 969 total) were analyzed. Blue Sky detected no significant QA/QC issues during review of the data. Note that 10,000 ppm = 1% and 1% = 1.1792% U3O8, 1% = 1.785% V2O5. All holes were drilled using NQ size aircore, unless stated in table 1 above HQ size aircore.
