ANIT Project - Exploration Results
Anit Exploration Results: 2010:
Blue Sky is currently conducting an ongoing intensive exploration program on ANIT. For the balance of the year work will include continued trenching, mechanical pitting, drilling and the commencement of metallurgical testing. A summary of the work completed to date is listed below.
Trenching: Blue Sky completed a trenching program consisting of four excavator trenches totaling 1,403m at the ANIT West and Central targets. Highlights included:
Trench 1 - 358 meters averaging 0.052% U3O8 and 0.159% V2O5
Trench 2 -- 114 meters averaging 0.019% U3O8 and 0.082% V2O5
Trench 3 -- 375 meters averaging 0.040% U3O8 and 0.057% V2O5
Trench 4 -- 91 meters averaging 0.066% U3O8 and 0.105% V2O5
The trenches were cut to a depth of approximately 2m and were designed to test the lateral extent and continuity of the mineralized paleo-channel that has been defined by pits along a minimum of 6km of strike length, within a larger 15km long radiometric uranium channel anomaly. This trenching program was the first mechanized exploration program conducted on the ANIT property. Results were released in March and July.
Drilling: Blue Sky announced in March the commencement of a Phase 1 drill program at ANIT, consisting of approximately 200 drill holes for a total of 5000 meters. The aircore drilling was planned to test 6 km of the known mineralized paleo-channel, defined by pits and trenching, as well as further targets in the 15 km long radiometric U anomaly. Exploration drilling will also test radon gas and new geochemical targets outside the principal airborne anomalies. Initial results from the first 97 drill holes in 2463 meters confirmed the existence of a surficial uranium-vanadium mineralized paleochannel. The weighted average grade from 81 of the first 97 holes completed that exceeded 50 ppm U over 1m is 0.03% over an average thickness of 2.6m. These holes were drilled along 5.2km of strike length in the ANIT West and Central sectors of the 15km long ANIT airborne U channel anomaly. Going forward where mineralization is mainly constrained to within 6m of surface much of the detailed sampling will be accomplished using excavator pits and trenches. Drilling, using calibrated gamma probe logging of all holes to for grade confirmation, will continue to be utilized for testing exploration targets and delineating mineralized zones below 6m depth.
2009:
During the second and third quarter of 2009, the Company carried out a surface exploration program to follow up on the 2008 surface work. In total 123 pits were hand excavated and 588 samples were analyzed. For descriptive purposes, the 15 km long airborne uranium anomaly has been subdivided into the West, Central and East zones. The work completed to date concentrated on the Western and Central zones with a total of 109 pits excavated of which 83 pits encountered mineralization. The average grade of the 280 samples taken from the 83 pits over the 6 kilometre strike length was 0.045% U3O8 (379 ppm U) and 475 ppm V with an average recorded mineralized interval of 1.7 meters from surface.
This surface exploration clearly defines a paleochannel/lake system that is mineralized over at least 6km of strike length. Of the 83 pits containing uranium-vanadium mineralization approximately 60% are open to depth, bottoming in mineralization. The depth extent of the uranium-vanadium mineralization is unknown due the limitations of hand digging test pits. At the Eastern Zone, located 8 km east along strike of the Central Zone, uranium mineralization is hosted in sediments and channel deposits approximately 25m stratigraphically below the Western and Central Zone mineralization. This suggests that there is potential for depth-continuity of the uranium mineralization in the West and Central zones.
Subsequent to the hand pitting program, hand augering from the base of previously excavated pits to further test the vertical extent of mineralization. Auger holes were completed on 41 selected pits on covering all areas of Anit West and Central zones. Prior to this augering program average pit depth was 2.2m, with a maximum depth of 3.1m. In the auger program the average extension of sampling was 1.1m, to bring average depth to 3.3m for 41 pits, with a maximum depth of sampling 6.5m depth. Of the 41 pits selected for augering, 29 had previously encountered mineralization greater than 1m at 0.005% (50 ppm) U. In 20 of these pits (34 samples) the mineralization was extended between 0.5 and 2.8m with average extension of 0.85m at 0.032 % U3O8 (270 ppm U) and 0.046% V. Of 12 pits with no previous mineralization, uranium mineralized material was encountered in the last sample of 3 auger extensions.
Augering from the base of Pit 225 (the highest-grade and thickest previously-reported mineralized interval with 3m averaging 0.849 % U3O8 (7200 ppm U) and 0.20% V) extended the mineralization a further 2.8m at an average grade of 0.033 % U3O8 (280 ppm U) and 0.04% V for a combined interval of 5.8m thickness averaging 0.436 % U3O8 (3700 ppm U) and 0.12% V.
In the area south of ANIT West where new radon anomalies (see below) indicate buried mineralization, previous pits 212 and 213 had no mineralization greater than 0.005% (50 ppm) U. Augering from the base of these pits has encountered U and V mineralization in the deepest auger samples. Pit 212 has 0.011% U3O8 (90 ppm U) and 0.124% V between 2.3 and 2.7m and pit 213 has 0.019% U3O8 (160 ppm U) and 0.037% V between 3.5 and 4m depth.The Company's exploration team has also completed a radon gas survey, density determinations and metallurgical sampling. Seven radon gas lines totaling 65km (5 x 10km, 1 x 8km and 1 x 7km), with radon detector cups spaced every 100m, and scintolometer cps recordings every 50m, were completed on the Anit 1 and 2 properties. Approximately 650 radon gas detection points were completed. Results from this survey are currently being evaluated and plotted. 5 pits (0.5 x 0.25 x 2m) were excavated measured and weighed for density calculations returning an average density 1361 kg/m3 and 9 bulk samples (average 40kg) from representative pits were collected for metallurgical testing.
The Company has filed for drill permits as it prepares for expanding its exploration activity on the ANIT project and within the region.
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 0.033% U3O8, 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 U3O8.
2008:
In 2008, five pits were hand-excavated within strong uranium-channel anomalies identified by the airborne radiometric survey. Yellow uranium-vanadium mineralization was most-concentrated in 10 to 20 cm layers exposed on the sides of the pits. In all cases uranium mineralization persists at least to the depth of the hand-excavated pits.
