CanAlaska intercepts 40.4 metres of uranium mineralization in basement rocks
at Fond Du Lac
Figure 1: http://www.canalaska.com/i/maps/092209CVV_mapfigure1.pdf
Further drill holes from the August program intercepted uranium mineralization in the basement and in the overlying sandstone. Significant assay results for the program are listed in Tables 1 and 2.
These drill results are the second set of significant assay results to be returned from summer work on the Fond Du Lac project. The Company previously reported on results from the West Fond Du Lac area, where a 2.4 km long zone of uranium stringer mineralization was re-sampled and mapped (see

The Fond Du Lac project is located on the northern portion of the Athabasca Basin, Saskatchewan, where the Athabasca sandstone units have minimal thicknesses of 20-75 metres overlying the unconformity. This area was explored by AMOK in the 1960's and AMOK and Eldorado Nuclear in the 1970's and early 1980's. The property is part of the Fond Du Lac Denesuline First Nation Reserve Lands, and CanAlaska is working with the community under an option to earn a 49% interest in the project. A small uranium resource (non 43-101 compliant) was previously discovered in the sandstone units, immediately above the unconformity. However, no significant effort was made to explore for structurally-hosted uranium mineralization in the basement rock at that time. The historic zones of uranium mineralization at Fond Du Lac are principally within the Manitou Falls Formation of the Athabasca Sandstone sequence, and are characterized by strong fracturing, intense silicification, zones of hematisation and minor clay alteration. Zoning is apparent, with a central highly-mineralized-core. The mineralization is evident as disseminations and replacement in the sandstone.
Figure 2: http://www.canalaska.com/i/maps/092209CVV_mapfigure2.pdf
The 2009 drilling at Fond Du Lac was successful on two fronts. The drilling defined a new mineralized extension to the historical deposit as well as significant uranium mineralization in the basement.
The intercepts in diamond drill hole FDL017 are located 70 metres North-East of the known uranium deposit, on the east side of a NNW trending mylonite zone. The mineralization occurs as narrow fracture fillings and breccia impregnation in mylonitic garnet-biotite gneisses. The main NNW structure was evident from the geophysical surveys performed by CanAlaska prior to the current drill programs (magnetics, VTEM, gravity and IP-resistivity surveys were carried out). The structural events appear younger than the main deformation associated with the Grease River Shear Zone, which cuts the property south of the area of current drilling.
The morphology of the new mineralized zone is not well known as yet, but appears to be trending in a general E-W direction and with a dip close to vertical. The known deposit to the southwest trends at 050 degrees; an orientation that is parallel to the regional Grease River Shear Zone. Airborne magnetic surveys show that the Grease River Shear fabric offset by the well-developed regional North-West fabric, and to a lesser extent, a North-South fabric.

During the 2009 drilling campaign, uranium mineralization was encountered along high angle structures in biotite gneiss basement rocks where the uranium occurs as coatings on fractures and as rims around fragments within healed breccia. The mineralization has been tested over a vertical extent of 68 metres in the basement, to a depth of 99 metres, with some associated mineralization also occurring in sandstone above this mineralized zone, for a total vertical extent of 90 metres. Associated geophysical features from IP geophysical surveys are shown in Figure 3.

The new drill information is currently being modeled and linked with prior geophysical results and known geological features. The IP-Chargeablity survey appears to show clear basement rock types, and the location of bounding structures (Figure 3). There is also good IP response over the area of the historical uranium deposit. Multiple drill targets have been identified by the Company's geologists. Some of these are formed from current drilling and surveys, whereas others are loosely-defined by correlating the location of mineralized boulder trains on surface (see attached Figure 4 for mineralized boulder trains and geophysical responses).

CanAlaska is presently fully-funded for its operations and is budgeting for extensive fall-winter 2010 exploration programs, financed by its strategic joint venture partnerships and from current treasury. The Company is presently awaiting further assay results from summer exploration that was undertaken on the Lake Athabasca Project, and from extensive mapping and sampling work at the Poplar Project, where the company has been working for the past month with six Chinese-trained geologists from East Resources Inc. The assay results from these active projects will be provided as they become available to the Company.
All of the prospecting and drill samples from the Fond Du Lac Project were submitted to Acme Laboratories

CanAlaska's geological expertise and high exploration profile has attracted the attention of major international strategic partners. Among others, Japanese conglomerate Mitsubishi Corporation has undertaken to provide the Company C$11 mil. in exploration funding for its West McArthur Project. Exploration of CanAlaska's Cree East Project is also progressing under a C$19 mil. joint venture with a consortium of Korean companies led by Hanwha Corporation, and comprising Korea Electric Power Corp., Korea Resources Corp. and SK Energy Co, Ltd. Exploration recently commenced on the Poplar Project with Chinese mining partner East Resources Inc., comprising a potential 100,000 metres of drill testing. In addition, Canadian explorer Kodiak Exploration has also optioned the McTavish Project to advance exploration with the goal of attaining a 60% project interest earn-in by delineating a minimum of 35 million pounds U(3)O(8).
