WestCan Uranium and CanAlaska Uranium Cut Rare Earth Mineralization at Key Lake

June 18, 2008

WestCan Uranium Corp. (TSX VENTURE: WCU)(OTCBB: WCURF)(FRANKFURT: IAR) (“WestCan”; “the Company”) and CanAlaska Uranium Ltd. (TSX VENTURE: CVV) (“CanAlaska”) have received final analytical results on core samples from diamond drill hole KEY005, drilled last winter on the Key Lake property, 12 kilometres south-west of the former producing Key Lake Uranium Mine, at the southeastern edge of the Athabasca basin in Saskatchewan. A 17.5 metre section of anomalous radioactivity was determined to have been caused by thorium. A 10.7 metre section was sampled and gave an average of 0.076% ThO2, with individual samples carrying up to 1.03% ThO2 across 0.05 metres. The thorium is accompanied by rare earth elements, with an average of 0.52% total rare earth elements (TREE) over the 10.7 metre interval. Individual samples assayed up to 6.35% TREE over 0.05 metres.

The rare earth mineralization consists mainly of light rare earth elements (lanthanum to samarium) with approximately 4% of the total consisting of the heavy rare earth elements (europium to ytterbium).

The mineralization is located in albitised white pegmatite within the lower part of a biotite gneiss assemblage. A sequence of pink, hematised pegmatitic granite follows the mineralised zone and the biotite gneiss. A thin section from the white pegmatite shows evidence of albititic metasomatism.

The partners plan to carry out additional sampling of the drill core to establish the full width of the mineralized zone. A second weaker radioactive zone at a depth of 196 metres depth will also be sampled in detail. Samples will also be collected for further mineralogical and petrographic study to determine the origin and significance of this unusual mineralization.

Dr. Colin Bowdidge, a director of WestCan, is the technical person responsible for this news release.

WestCan also wishes to announce that Dr. K.W. Geiger is currently travelling to Regina, Saskatchewan, to commence research on a 9,000 hectare Coal property, following the receipt of a “Comfort Letter” from the Saskatchewan Ministry of Energy and Resource (see Stockwatch June 10, 2008).

The Company intends that such forward-looking statements be subject to the safe harbours created thereby.
