Blue Sky Makes Important Discovery In Rio Negro, Argentina

Blue Sky Uranium Corp. (TSX-V: BSK) ("Blue Sky") is very pleased to announce the analytical results from pit sampling on its 100% owned ANIT project in Rio Negro Province, Argentina. Blue Sky’s pitting program has defined a paleochannel/lake system that has extensive high grade uranium and vanadium mineralization over at least 6km of strike length. The best mineralized interval, averaging 0.72% uranium (U) and 0.20% vanadium (V) over 3 metres vertical thickness, extends from surface and remains open to depth, with an individual assays from 0.5m channel samples returning high grades of up to 1.8% uranium.

The average grade of the mineralized paleochannel from 83 pits covering the ANIT West and Central zones over a strike length of 6km is 0.045% U3O8 (379 ppm U) and 475 ppm V with an average recorded thickness of 1.7m. Of the 83 mineralized pits, approximately 60% are open to depth having bottomed in mineralization. Blue Sky is now planning a program to test the depth extensions of the observed paleochannel system and for stacked channels below.

Mineralization has been identified in three zones, Eastern, Central and Western, along a 15 kilometre radiometric anomaly. Approximately 8 km east along strike of the Central Zone, uranium mineralization in the Eastern Zone in channel deposits is approximately 25m below the Western and Central Zone mineralization indicating potential at depth.

At this early stage of exploration, Blue Sky interprets the ANIT anomaly to be a paleochannel- or surficial- type uranium occurrence similar in style to known deposits in Western Australia (Lake Maitland NI43-101 compliant inferred resource of 23.7 million lbs U3O8 at an average grade of 0.03% U3O8,1 and in Namibia (Langer Heinrich deposit with Measured and Indicated Resources of 56.4Mt grading 0.06% containing 72.4 million pounds lbs of U3O8 and Inferred Resources of 70.7Mt grading 0.06% containing 91.6 million lbs of U3O82.

“Our exploration at ANIT has identified a brand new grass roots discovery that is the first of its kind in the region and also clearly shows the potential of this new district to host significant discoveries such as those in Namibia and Western Australia. Blue Sky’s future exploration will not only focus on the depth potential at ANIT, but we also intend to expand our efforts regionally in a cost effect and socio-economically responsible manner.” Mr. Sean Hurd, President & C.E.O.

Blue Sky, as a Grosso Group member company, is strongly committed to develop its projects in conformity and in co-operation with the Community and Government of Rio Negro.

Technical Summary

A total of 123 pits with 588 samples have been completed by Blue Sky’s field crew to date on the ANIT properties. The hand-dug pits are generally 1.0m wide and between 1.5m and 3.0m deep. The pits were located to follow up on the 5 discovery pits previously reported on within the 15km long strong uranium-channel anomaly identified by the September 2007 airborne radiometric survey flown over the property (see press release dated Nov. 24, 2008). The 15 km long ANIT airborne U anomaly has been subdivided into the West, Central and East zones for discussion purposes.

In the ANIT West and ANIT Central zones a total of 109 pits were excavated, of which 280 samples collected from 83 mineralized pits dug over 6 km of strike length average 379 ppm U and 475 ppm V. The work completed to date, concentrated on the Western and Central zones of the anomaly, clearly defines a paleochannel/lake system that is strongly mineralized over at least 6km of strike length. The Central anomaly is 1,000m long and averages 200m wide. In the remaining 5km of strike length that includes the West zone and its extension east to the Central zone, a paleochannel is always present in excavated pits, but width has not been constrained to date and is generally defined by only one or two pits. Detailed ground scintillometer surveys and limited pit sampling suggests that the paleochannel resembles a braided stream system ranging from a few tens of metres to several hundred in metres width. Mineralization occurs primarily as yellow carnotite crystals filling open spaces, coating grains and clasts hosted by inter-layered unconsolidated sands, gravels, clay-rich lake sediments and evaporates, that are either exposed on surface or lying below shallow soil cover.

Of the 83 pits containing uranium-vanadium mineralization approximately 60% are open to depth, bottoming in mineralization. In some of the deeper pits stacked mineralized channels are observed where the profile changes from strongly mineralized gravel at surface to weak or non-mineralized clay horizons, before re-entering strongly mineralized gravel at the bottom of the pit. The depth extent of the uranium-vanadium mineralization is uncertain due the limitations in hand digging test pits (maximum depth is 3.5 metres). The Eastern Zone, located 8 km east along strike of the Central Zone, is interesting in that uranium mineralization there is hosted in Cretaceous sediments and channel deposits approximately 25m stratigraphically below the Western and Central Zone mineralization. This suggests that there maybe considerable potential for depth-continuity of the uranium mineralization.

The ANIT project is easily accessible year round via well maintained gravel roads and is located at an elevation of less than 200 metres. The region has a low population density and rainfall of less than 300mm per year. The project is 200 km from a deep sea port, 100 km from rail lines, a four hour drive from an international airport and high tension power lines are located nearby.

On the Santa Barbara property in Rio Negro (approximately 50km north of ANIT) 90 shallow hand auger holes and pits were completed on 3 airborne uranium channel anomalies with a combined strike length of approximately 20km. From this very broad scale sampling several mineralized zones were detected with values up to 727 ppm U from a 0.5m sample. Although many mineralized assays were received, thicknesses are generally 0.5m or 1.0m. The Company is continuing prospect and sample the large Santa Barbara concession to identify zones with higher grades and increased thicknesses.

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). The samples collected from the pits were 0.5 or 0.6 meter composites taken from 4 channel samples (one on each pit wall face). The 4 samples were mixed, then split, with a 1kg sample sent to Alex Stewart Assayers. The remaining sample material was retained in storage on the project site for future use and reference. Blank, duplicate, and internal company standard samples were inserted into the sample sequence sent to the lab for quality assurance/quality control (QA/QC) purposes. In total, 76 quality control samples (12.9% of all 588 samples) were analyzed. Blue Sky detected no significant QA/QC issues during review of the data.
