VANCOUVER, Aug. 29 /CNW/ - CanAlaska Ventures Ltd. is pleased to report
the first quantitative results from uranium exploration and sampling at the
Company's North East Athabasca Project. This large project consists of
490,340 acres (1984 km(2)) and straddles the Saskatchewan-Manitoba border.

<<
-------------------------------------------------------------------------
Highlights:

- Extensive uranium mineralisation in basement immediately to north of
Athabasca contact
- Uranium boulder trains 0.2% to 3.65% U3O8 on surface
- 14 target zones, with 6 priority zones identified
- Blanket coverage with over 1,900 lake sediment samples
- New outcrop discoveries of 0.31% to 0.81% uranium from current work

-------------------------------------------------------------------------

Athabasca sandstone outliers to the west and south (Reilly Basin)
indicate the strong possibility that this area was once covered by Athabasca
sandstone. The North East Project exploration licences cover the northern
extension of the Wollaston Belt, which underlies all of the major uranium
mines in the eastern Athabasca Basin.
This summer the Company has carried out detailed lake sediment sampling
over the entire licence area, and is awaiting results on the majority of the
1,900 individual lake samples. Previous exploration work in the North East
Project area in the late 1970s identified uranium boulder trains and
uranium-rich lake sediments. CanAlaska's current program of surface follow-up
and prospecting with a field staff of 15 geologists and prospectors has led to
the discovery of new areas of mineralised boulders and outcrops.
The Company has defined fourteen anomalous zones. Of these, seven have
had previous exploration, and seven are either new zones or significant
additions to previous work. The geochemical results obtained from the early
part of this year's survey of six of the zones are tabulated below. An
extensive boulder field in the Hook Lake Zone has uranium values from 0.2% to
3.65% U3O8 (4 lb - 73 lb / ton U3O8), and is located south of mineralised
outcropping zones of pelitic gneiss which have returned preliminary values
from 0.31% to 0.81% U3O8 (6.2 lb - 16.2 lb / ton U3O8). Significant molybdenum
mineralisation is associated with most samples, along with occasional higher
gold values. These priority areas are now receiving detailed follow-up
exploration by the Company's field crews to establish drill testing
priorities.

About the Athabasca Basin

The Athabasca Basin hosts a number of major uranium deposits including
Cigar Lake and McArthur River, two of the largest and highest grade uranium
deposits in the world. Production from the Athabasca Basin accounts for over
30% of the world's supply of uranium. For the past two decades, uranium
exploration within the Athabasca Basin has been at a relatively low level and
it is evident that the potential for the discovery of other deposits remains
high. Peter Dasler, President of CanAlaska, has noted that "before commencing
our staking program, CanAlaska carried out a comprehensive analysis of
existing geological and geophysical data, and the Company has identified and
acquired properties that are well located and have considerable potential. The
results of our initial airborne surveys have produced targets which support
this potential."
The Company and its shareholders are positioned for what CanAlaska
believes will be the largest expansion in uranium exploration since the 1970s.
Harry Barr, Chairman of CanAlaska has stated, "CanAlaska holds one of the
largest uranium exploration portfolios in the Athabasca Basin and is actively
exploring its properties."
The qualified person for this release is Peter Dasler, P.Geo, President
of CanAlaska Ventures Ltd.
