CanAlaska Uranium Ltd. – Summer Exploration to Commence at Poplar Uranium Project

Vancouver, Canada, June 25th, 2009 – CanAlaska Uranium Ltd. (TSX.V — CVV) (“CanAlaska” or the “Company”) is pleased to announce that it has executed a Memorandum of Understanding (“MOU”) with East Resources, Inc. (“ERI”) to commence exploration of the Company’s Poplar uranium project (“Project”), located in the Province of Saskatchewan on the northern rim of Canada’s Athabasca Basin. In December, 2008, ERI had executed a similar agreement with the Company to undertake uranium exploration at the Company’s NE Wollaston project in the Province of Manitoba. However, due to continual delays encountered since the Fall of 2007 with the award of exploration permits by the Government of Manitoba arising from prolonged consultations with native communities, both CanAlaska and ERI have opted to initiate their cooperation by first conducting uranium exploration in Saskatchewan.Under the terms of the MOU, ERI may earn a 40% interest in the Poplar project by undertaking a minimum of 100,000 metres of diamond drilling within 5 years. ERI may earn a 70% interest in the project by undertaking a minimum of 50,000 metres of diamond drilling, successfully completing a feasibility study for a minimum economic reserve of 15 million pounds U3O8 and fully-financing the costs of mine construction. ERI may earn an 80% interest in the Project by undertaking a minimum of 50,000 metres of diamond drilling, successfully completing a feasibility study for a minimum economic reserve of 35 million pounds U3O8 and fully-financing the costs of mine construction.
