CanAlaska Uranium Reports on Cree East Summer Drill Program

Vancouver, Canada, September 28th, 2010 — CanAlaska Uranium Ltd. (CVV — TSX.V) (the “Company” or “CanAlaska”) is pleased to present the preliminary results for summer drilling on the company’s Cree East uranium project (the “Project”) in the South Eastern Athabasca Basin. The Project is a joint venture between CanAlaska and the Korean Consortium (the “Joint Venture), comprising Hanwha, Korea Electric Power. (KEPCO), Korea Resources (KORES) and SK Energy. At the present time, the Korean Consortium owns a 43% ownership interest in the Joint Venture.

Cree East – Developing Targets

Drilling has just finished on the Project, which is operated by CanAlaska on behalf of the Joint Venture. A total of 10,060 metres was drilled in the summer season, comprising drill holes CRE044 to CRE070. Twenty two of the drill holes were successfully completed to intended basement depths. The drilling targeted three areas, Zones A, G and H. In Zones A and G, the drill holes progressively intersected broken rock and disaggregated sandstone overlying hydrothermal clay alteration and hematite-rich uranium bearing zones. These alteration zones are similar to those customarily recognized as surrounding the various known Athabasca uranium deposits.

Zone G-H drilling

There is significant basement-hosted uranium mineralization within drill holes across the postulated trend of the mineral belt through Zone G in the southern portion of the property.

Gamma probe analyses show a short section registering up to 4,680 cps in DDH CRE047, and flanked by very high background radiation over 300 metres in adjacent holes CRE045, CRE049 and CRE057 (see N-S Cross Section G-G’1 in Figure 3). There is also high background uranium in the basement sections of holes CRE029, CRE030 and CRE033, located 300 metres further east along the E-W Long Section G1-G1′ (see following Figure 2, Long Section).

On section G-G’, graphitic pelite horizons were intersected in drill hole CRE049, and gamma probing registered up to 4,750 cps, indicating uranium mineralization (see table below). The main structural breaks (up to 28 metres vertical offsets) now lie within gaps in the drill fences and are confined to within 100-150 metre separations between drill holes. These narrow gaps now host the main targets in area G (See Figure 2). Drill hole CRE049 is marked by a series of mineralized intersections from 336 metres to nearly the end of the drill hole at 414 metres depth.

Immediately to the west of Zone G, a fence of three reconnaissance holes were drilled in Zone H. Graphitic pelites were intersected in the central drill hole of the fence. Drill hole CRE055 in the west showed the most fracturing in the sandstone, and further drill holes are required. The intense sandstone alteration in this area confirms the early geophysical survey interpretations, and that a hydrothermal system is located in the vicinity.

Zone A Drilling
At target Zone A, the prime focus of this season’s drilling, activity was suspended in mid-summer due to forest fire activity, but resumed in early September. In this area, the Company had previously defined a major E-W break associated with hydrothermal alteration in the sandstone and basement rocks.

A series of holes across the main E-W fault break intersected further intense hematization and clay mineralization, as well as a narrow zone of pitchblende (U3O8) mineralization in a brecciated marble unit, in drill hole CRE067. The location of CRE067 is on the south side of the main fault zone, but 100 metres east of the previous drilling. The pitchblende mineralization and intense clay alteration is considered an important vector towards the centre of the mineralizing event. Of particular importance is the intersection containing a wide section of sudoite clay alteration high up in the sandstone in holes CRE048, CRE063 and CRE067. This is accompanied by a thickening of the sudoite section near the unconformity. Infill drilling is now required to test the extent of this mineralization and to follow the offset of the graphitic pelite horizon in this area.

Note:. – In Table 1, ”Equivalent Uranium grades” (eU) have been calculated using a dead-time correction and K factor specific to each natural gamma probe based on calibration runs in the Saskatchewan Research Council test pits. Equivalent uranium grade assumes that in these mineralized intersections, the radioactivity is produced by uranium and that there are only negligible amounts of other radioactive elements present.

Korean Tomography Testwork
During August, the Project hosted a visit by a Korean technical team from Uranium Research & Development Organization (URDO), who rendered assistance to the Project in deploying a new geophysical survey technique utilizing 3D Resistivity Tomography. The URDO technical team is supported by the Korean Government, and is tasked with testing geophysical techniques to better image Athabasca uranium deposits.

Field measurements provided high contrast results, which both CanAlaska and URDO believe will provide additional interpretative data for the Project following normal processing. These tomography surveys are directed towards imaging geophysical features that exist between drill holes and at depth. Results from the first surveys are expected in late-November and will be reported when received.

Following the full compilation and analysis of this summer’s drilling results, CanAlaska expects to pursue another significant drill program on the Project commencing in January 2011.

President Peter Dasler states. “The Cree East project represents a very large area with previously untested potential for uranium mineralization. The current drilling has significantly increased our knowledge of two of the ten target zones which have been identified from the past two years of field work and we have made major advances towards a potential discovery in Zones G and A.
