CanAlaska Uranium Announces Extensive RARE EARTH Mineralization at NE
Wollaston Project

VANCOUVER , Oct. 20 /CNW/ - CanAlaska Uranium Ltd. (CVV - TSX.V) (the "Company") is pleased to be able to detail extensive zones of heavy and light rare earth mineralization in surface rocks and boulder trains on the North East Wollaston project.

Total Rare Earth Element (REE) mineralization ranging from 0.2% to 10% is reported, and in many cases it is the most valuable component of the samples. In other samples it occurs as a significant potential by-product from uranium or base-metal mineralized zones. Because of the varying ratio of heavy to light REE, the in-situ value is quite variable, anywhere from less that $20 per tonne to over $1000 per tonne in contained REE. It is significant to highlight these very good mineral values at a time when REE minerals are being identified as important commodities for industrial development.

These zones of REE mineralization are often in association with uranium or thorium mineralization, and are relatively easily prospected by scintillometer traverses, or from airborne radiometric surveys. Most of these reported samples are from radioactive boulders, sampled for uranium. No specific search was made for REE bearing rocks at that time, but all current targets will now be followed up.

The extensive results tables presented in this news release also detail the uranium and molybdenum mineralization samples in the zones. Further detail on the individual zones is in the news release dated February 8 2008.

The NE Wollaston project area, located in Manitoba, northeast of the Athabasca Basin uranium deposits, is shown in the attached location map. Historically this area was explored for base metal mineralization, (1960's-1980). In the early 1980's, reconnaissance work identified several areas with anomalous uranium mineralization. In 2004, CanAlaska acquired the mineral licences in the area and began systematic prospecting and lake sediment sampling through to 2007, and made the REE discoveries.

The following tables show the REE mineralization in the samples collected by CanAlaska personnel:

The Company has been is awaiting local and Government approvals and work permits to re-commence work on the project areas, and has now been informed by the community and the Manitoba Government that the next stages of exploration should be able to re-commence in 2010.

President Peter Dasler commented "The process of community consultation has been slow, but we have always intended to build a strong foundation for many years of work and success in this region. To do this, all stakeholders must be considered."

All of the samples from the exploration programs were submitted to qualified Canadian laboratories for analysis. Samples submitted to Saskatchewan Research Laboratories were analysed for multi-element geochemistry and including uranium by tri-acid digestion and ICP. Samples submitted to Acme Laboratories in Vancouver , BC for assay for trace element geochemistry were analysed by aqua regia digestion and ICP analysis. The samples were collected by CanAlaska field geologists under the supervision of Dr. Karl Schimann , P. Geo. and were shipped in secure containment to the laboratories noted above. Peter Dasler, M.Sc. P Geo. is the qualified technical person responsible for this news release.

About CanAlaska Uranium Ltd. - www.canalaska.com

CANALASKA URANIUM LTD. (CVV - TSX.V, CVVUF - OTCBB, DH7 - Frankfurt ) is undertaking uranium exploration in twenty 100%-owned and three optioned uranium projects in Canada's Athabasca Basin -- the " Saudi Arabia of Uranium". Since September 2004 , the Company has aggressively acquired one of the largest land positions in the region, comprising over 2,500,000 acres (10,117 sq. km or 3,906 sq. miles). To-date, CanAlaska has expended over Cdn$55 million exploring its properties and has delineated multiple uranium targets.

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).
