WU White Canyon Uranium Ltd Ord

Further to the release made by White Canyon Uranium Limited (TSX VENTURE: WU)(ASX: WCU) ("White Canyon" or the "Company") on February 25, 2011 regarding the recently completed sale of 107,000 pounds of U308, the Company wishes to advise that:

--  The gross proceeds from the completed sale were US$7.4 million;

--  The cost of the milling process (including milling, receiving, selling
    and other attendant costs) to the Company was determined pursuant to the
    Toll Milling Agreement (dated January 2010). This cost was settled by
    the Company predominantly in-kind in U3O8 due to the fact that at the
    time of commencement of milling (November 2010) the Company had limited
    cash resources required to pay Denison Mines Corp. (TSX: DML)(NYSE
    Amex:DNN) ("Denison") for undertaking the milling. The Company
    transferred 86,650 pounds of U3O8 to Denison under the provisions of the
    Sales Agency Agreement with Denison (dated October 2010);

--  Overall, the milling of the initial ore and the subsequent sale of U3O8
    was carried out in accordance with the provisions of the Toll Milling
    Agreement (dated January 2010) and Sales Agency Agreement (dated October
    2010); and

--  Following both the sale of the Company's U3O8 and the in-kind payment of
    milling costs, and given the first milling run yielded 204,450 pounds of
    U308, White Canyon Uranium has 10,800 pounds of U3O8 remaining, of which
    10,223 pounds of U3O8 represents a holdback pending final accounting
    with respect to the milling process and, along with the remaining 577
    pounds of U3O8, will be offered for sale when released.
