ROCA-Notice of Intention to Make Normal Course Issuer Bid

VANCOUVER, BRITISH COLUMBIA ("Roca" or "the Company") has filed with the TSX Venture Exchange (the "Exchange") a notice of its intention to make a normal course issuer bid (the "Bid") for its common shares through the facilities of the Exchange.

A maximum of 4,078,500 common shares, representing approximately 5% of the issued and outstanding common shares in the Company, will be eligible for purchase in the 12-month period commencing June 2, 2008, and ending on June 1, 2009. Pursuant to the policies of the Exchange, Roca is permitted to re-purchase through open market purchases, up to 2% of its outstanding common shares in any given 30 day period.

The price that the Company will pay for any such common shares will be the market price at the time of acquisition and any common shares purchased pursuant to the Bid will be cancelled. The actual number of common shares that may be purchased and the timing of any such purchases will be determined by Roca based upon market and investment considerations. As of the date hereof, there are 81,570,328 common shares of Roca issued and outstanding.

The Company considers the Bid to be in the best interest of the Company and its shareholders. Any re-purchase by the Company of its shares would be for its own corporate purposes and reasons. The Company believes that there may be times over the course of the year when its common shares may trade in a price range that does not adequately reflect their value in relation to Roca's business and its future business prospects. As a result, depending on future price movements and other factors, Roca believes that its outstanding common shares may represent an attractive investment and a desirable use of a portion of its available funds. The re-purchase by the Company of any of its shares should not be deemed or construed as a recommendation to purchase any of its shares or an indication of the present or future value of the Company's shares.

The name of the member conducting the Bid on behalf of Roca is Desjardins Securities Inc.

Shareholders may obtain a copy of the notice by contacting Roca's head office.
