A 50:50 joint venture has been established between CanAlaska West McArthur Uranium Ltd., a wholly-owned subsidiary of the Company, and MC Resources Canada Ltd. CanAlaska West McArthur Uranium is the Operator of the joint venture.

The Company has already commenced exploration work for the 2010 Winter season. Geophysical crews started fieldwork in preparation for a $3.5m drill program on the West McArthur project. A drill contract for a minimum of 6,500 metres of drilling, utilizing two drill rigs has now been executed with Cyr Drilling International Ltd. Cyr Drilling has worked with the Company on drill projects at West McArthur since 2005, and is well-provisioned to complete this winter's drill program. The Company has been particularly anxious to re-commence drill testing on the Grid 1-2 area of the project, which has been in hiatus for the past two years. Prior drilling by the Company in this area had intercepted trace uranium mineralization in three separate drill holes. The nature of the alteration associated with the drilling, as well as from earlier geophysical surveys, indicated a number of discrete targets "A" to "D" in the Grid 1-2 area, as shown in Figure 1, which have been the subject of intense review, re-testing and prioritization for the past field seasons. At least seven drill holes will be completed over the winter season on these high-priority targets. (see May 29, 2007 News Release for images of the geophysical responses and previous drill holes, alteration and mineralization).

Peter Dasler, President & CEO, commented, "We are very pleased to have been able to work with Mitsubishi for the past four years in expanding the knowledge of this very strategic project. We are located in a very mineral-rich area, adjoining one of the largest uranium mines in the world. Our preliminary work and drilling has indicated the style of targets that hold promise for significant uranium discovery. The strength and continued support of Mitsubishi Corporation is allowing us to reach for our goals."
