Vancouver, BC - December 23, 2008, Pediment Exploration Ltd. (TSXV: PEZ) ("Pediment" or the "Company") announces a correction in the number of stock options cancelled and granted as first announced in its December 12, 2008 news release.

The Company previously announced that 400,000 options priced at $1.88 and 840,000 options priced at $3.00, for a total of 1,240,000 options, which were previously granted to certain employees, consultants, directors and officers, had been cancelled. However, there are only 745,000 options priced at $3.00 that are currently outstanding so the total number of options being cancelled by the Company at this time is 1,145,000 rather than 1,240,000.

In addition, a total of 1,270,000 new options have been granted at a price of $0.60 per share, not 1,900,000 new options as previously announced. Certain of the new incentive stock options that have been granted to insiders will not be exercisable by the holders until the grants are ratified by disinterested shareholders at the Company's 2009 Annual General Meeting and are accepted for filing by the TSX Venture Exchange.
