CanAlaska Options McTavish Uranium Project

Vancouver, Canada, Aug 10th, 2009 – CanAlaska Uranium Ltd. (TSX.V — CVV) (“CanAlaska” or the “Company”) is pleased to announce that it has entered into an option agreement with Kodiak Exploration Limited (KXL — TSX.V) (“Kodiak”) with regard to the Company’s 100%-owned McTavish uranium project (“Project”), situated in the prolific Athabasca Basin of northern Saskatchewan.

Pursuant to the recent execution of an option agreement, Kodiak has been granted an option to acquire up to a 70% interest in the Project. In order to earn an initial 50% interest in the Project, Kodiak must complete $4,000,000 in exploration and issue 1,000,000 Kodiak shares to CanAlaska in accordance with the following schedule: 100,000 Kodiak Shares on or before the Effective Date; such payment to be made within 10 business days after the date of acceptance (the “Effective Date”) by the TSX Venture Exchange of a filing to be made in respect of the proposed option;
$600,000 Expenditures and 50,000 Kodiak Shares by the first anniversary of the Effective Date;
a further $800,000 Expenditures and 50,000 Kodiak Shares on or prior to the second anniversary of the Effective Date;
a further $1,200,000 Expenditures and 50,000 Kodiak Shares on or prior to the third anniversary of the Effective Date;
a further $1,400,000 Expenditures and 50,000 Kodiak Shares on or prior to the fourth anniversary of the Effective Date; and
a further 700,000 Kodiak Shares on or prior to the fifth anniversary of the Effective Date
Kodiak may earn a further 10% interest in the Project (60% total), by expending $3,000,000 in exploration/pre-feasibility work over an additional three year period, issuing an additional 550,000 Kodiak shares and producing a 43-101 compliant resource estimate containing at least 35 million pounds U3O8 in the measured and indicated categories. By defining a resource of 50 million pounds U3O8 during the same period, Kodiak’s interest may increase to 70%. The proposed option is subject to acceptance by the TSX Venture Exchange.

The McTavish Project consists of three separate claim groups totaling 16,385 hectares. One claim group is wholly-enclosed by Kodiak’s West Millennium project. The other two parcels are intimately intertwined with West Millennium. UTEM data show that the conductors successfully drilled by Kodiak this past winter at West Millennium extend onto the McTavish property and appear to intensify. Previously announced Kodiak drill hole WM09-04, which intersected a 69 metre thick fractured graphitic and pyritic pelite unit containing up to 0.13% U3O8, is located only 400 metres from the McTavish property and underscores the excellent exploration potential of the Project. UTEM data also defines two other large scale, high magnitude conductors on the McTavish property, both of which are untested by drilling. The combined West Millennium-McTavish property package comprises nearly 380 km2 in the heart of the Athabasca Basin, only three kilometres west of Cameco’s Millennium deposit (47M pounds U3O8 with an average grade of 4.5% U3O8).

CanAlaska is very pleased to enter into the option agreement with Kodiak. It will allow for immediate exploration of the significant geophysical features identified by CanAlaska’s VTEM airborne surveys, which are preserved on the CanAlaska claim blocks.
