CanAlaska Uranium Reports Drill Results From Collins Bay Extension Project

Vancouver, Canada, August 19th, 2010 — CanAlaska Uranium Ltd. (CVV — TSX.V) (the “Company” or “CanAlaska”) is pleased to report on its exploration activities at the Collins Bay Extension project, with assay results from Fife Island, where drilling in April 2010 established multiple uranium bearing zones, and the commencement of seismic profiling of the Blue Island diatreme target. The Collins Bay Extension project was optioned from Bayswater Uranium in 2009 (see July 15th, 2009 News Release). It is situated immediately adjacent to the current producing underground Eagle Point mine and the past producing open pit mines of Collins Bay and Rabbit Lake, mined by Cameco Corporation and its predecessors.
Uranium mineralization in drill core from hole CBX002 measured 4.7 metres assaying 0.043% U3O8, where stringer zones of uranium mineralization were identified within a north west trending fault splay on the Vic zone at Fife Island. This is in the same area where drilling in 1981 intercepted 4.0 metres of 0.152% U3O8 (in DDH MWL-D-8). In the following table there are both assay and radiometric probe results from April’s drilling. Drill holes CBX001 to CBX005 are from the Fife Island target, and the CBX006C assay is from one of the deeper fault zones on the Blue Island diatreme target. The first drill hole in April 2010 was southwest of Blue Island on the western of two circular geophysical anomalies. Drill hole CBX006 showed strong evidence of an extensive disruptive geological event associated with the circular features, with brecciation continuing to the end of the drill hole. The probe results are from zones where there was limited, or no recovery of core.


The Company is currently carrying out seismic survey profiling of the lake and basement terrain across the Blue Island target. This profiling will be used to identify major structures within the diatreme in preparation for Winter 2011 drilling. Preliminary results (see Figure 2) indicate that modeling will be able to provide significant detail on the target.

President Peter Dasler commented: “The Blue Island target is a large new feature in this area of the Athabasca Basin, and we are pleasantly surprised by the amount of breccia intersected in the drill hole. Other areas of the Athabasca Basin have circular structures associated with brecciation, alteration and uranium mineralization. This is a discrete target, and it is very encouraging that the first drill hole has given us evidence of uranium mineralization associated with the breccias.”
Summer Exploration Update
CanAlaska is currently operating two drills at the Cree East Project, and is co-ordinating a drill program on the Grease River project, expected to commence shortly. A ZTEM survey has just been completed on the West McArthur project, and a management meeting will be held this month to plan for early 2011 work on this project.
