| Location |
| This
large project covers a section of Lake Athabasca southwest of
the formerly producing Uranium City area, a major source area of
uranium in basement rocks where former mine production was some
65 million pounds U3O8. The property
includes both the lake and islands. Lake water depths vary from
0 to 97 metres and are shallower than 50 metres throughout a
large part of the project. |

| Geology |
| Outcrops
of Athabasca sandstone occur on islands near the northeast
corner of the project and on Beartooth Island on an adjoining
property south of the west end of the project area. This implies
that Athabasca Group rocks unconformably overlie the basement
rocks of the Beaverlodge and Zemlack domains throughout the
project area. Both of these domains are extremely rich in
granite hosted shear and vein Uranium mineralization, and are
home to several past-producing uranium mines. The geology of
these domains is heavily metamorphosed Archean rocks, intruded
by Lower Proterozoic plutons and then deformed by the
Trans-Hudson orogen which lead to the creation of fault bound
sedimentary basins. These were then covered by the Flat-lying
Athabasca sandstones and conglomerates to a depth of 300 metres. |

|
| Exploration |
| The
project area was explored by Eldorado in the 1970's, during
which the Stewart Island showing was located and drilled. In
addition, numerous other geological and geophysical studies were
completed. CanAlaska has used GIS in compiling these existing
datasets and has assimilated them to create a powerful
exploration tool. |

|
| Potential |
| The
potential of this project is for unconformity style uranium
mineralization of both the Simple (Low REE, basement hosted) and
the Complex (High REE, Sandstone hosted) types of Uranium.
The Gunnar Mine, second largest producer in the Uranium City
area, lies a few km north of the project area and showings of
uranium in Athabasca rocks occur on, and near the northeast part
of the project. A Megatemtm survey was flown for
CanAlaska in 2005, which has sharply redefined the known
conductor and has delineated new conductors. |
