Blue Sky Reports Pit Samples from ANIT Drill Hole Sites and Trenching Cuts 91 Meters Grading 0.066% U3O8
Blue Sky Uranium Corp. (TSX-V: BSK, WKN: AOMKXP) is pleased to announce that it has completed an initial review of the variation between pit and drill hole sampling results at its ANIT uranium project in Rio Negro Province, Argentina. The review suggests that the assay results from the drill program released to date may have significantly under reported actual U3O8 grades. This preliminary analysis is based upon the assay results from pits dug over 25 drill holes that on average reported 50% higher U3O8 grades compared with the grades from the correspondingly-located drill hole over the same 3 meter interval.

These preliminary results have helped establish a new exploration protocol at ANIT whereby all drill-defined mineralization within 6 meters of surface will be verified with corresponding excavator sampling pits and trenches. Mineralization encountered below 6 meters will be checked using calibrated gamma probe logging of all holes to ensure accurate sampling of the mineralization.

The Company is also pleased to announce the assay results from Trench 4 that cut a 91 meter interval of higher grade mineralization, between 89 meters and 180 meters within a 180 meter trench. The mineralization occurs over at least 2 meters vertical thickness beginning at 0.3 meters below surface and averaging 0.066% U3O8 and 0.071% V2O5. The interval included a high-grade zone of 33 meters grading 0.154% U3O8 and 0.105% V2O5. The mineralization in the trench remains open to depth and along strike (see attached map).

The ANIT target is an unconsolidated paleochannel that is comparable to advanced development projects and operating mines. See Table 1 below.

* AREVA purchased "Trekkopje and Klein Trekkopje" by paying USD $2.5 Billion to acquire Uramin Inc. The project is expected to be in production in 2010, with full production in 2011.Trekkopje grades 0.013 % U3O8 and is hosted in mostly hard rock where 80% requires drilling and blasting. In contrast, Blue Sky's "ANIT" is hosted in sand and gravel and grades 0.03 %.

Trench 4 was designed to facilitate greater understanding of the controls on and distribution of mineralization at ANIT. The trench was located between the ANIT West and Central zones and is oriented perpendicular to previously reported Trench 2 in the same area. In this area where the radiometric anomaly appears to constrict between ANIT West and Central, the grade of uranium mineralization appears to be higher than in other areas of the paleochannel.

Trench 4 was sampled over a 2 meter vertical interval, with one sample for each 1m2 area, starting at 0.3m to 0.5m below surface. Each square meter was sampled with 2 continuous channel samples, one vertical and one horizontal, that were combined to make one sample. The mineralized sections quoted above represent 2m thicknesses and are the average of all samples on the face of the trench. Between 0 and 89m sporadic lower grade mineralization was detected with 18 samples out of 112 above cut off grade of 1m at 0.006% U3O8 (50 ppm U).

Management initiated the sampling review to determine why a significant variation in assay results between the drilling and historical pit sampling program was occurring. The 25 pits, measuring 1 meter square and 3 meters deep, were located over a selection of the 97 drill hole sites in ANIT West and Central representing a range of grades reported in the June 16, 2010 news release (see Table 2). Sampling was carried out using both 1 meter and 0.5 meter vertical sample intervals in each pit. A high degree of variability between reported average grades from the top 3 meters of aircore drillholes and pit sampling in the same location was observed (grade variability is known to be a common feature of similar style paleochannel deposits), however, on average pit sampling returned greater than 50% higher results for uranium when averaged over 3 meters. Greater variability is observed in the lower-grade portion of the data set. Correlation between the 1 meter and 0.5 meter averaged vertical channel samples was high. Based upon the results of the review it is now believed that the drill rig is unable to adequately capture all the fine material produced and due to the unconsolidated and variable nature of the deposit, a larger sample than that produced by the drill rig may be needed to produce a representative sample.

The following table shows the grade variation between the reported drill holes and the 25 sampling pits.

Analyses of samples 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, 33 quality control samples from trenching (15 % of 216 total) were analyzed. Blue Sky detected no significant QA/QC issues during review of the data. In total, 43 quality control samples from pits (14 % of 293 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.
