Minefinders to Renew Base Shelf Prospectus

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 11/24/10 -- Minefinders Corporation Ltd. (TSX: MFL)(NYSE Amex: MFN) today reported that it is renewing its existing short form base shelf prospectus, which expires January 1, 2011, and has filed a preliminary short form base shelf prospectus with the securities regulatory authorities in each of the provinces of Canada, except in the province of Quebec, and a corresponding registration statement on Form F-10 with the United States Securities and Exchange Commission (collectively, the 'Base Shelf').

The Base Shelf, when final and effective, permits Minefinders to offer and sell common shares, warrants to purchase common shares, share purchase contracts, subscription receipts and debt securities (collectively, the 'Securities') or any combination thereof up to an aggregate offering size of US$250,000,000 during the 25-month period that the Base Shelf remains effective. Securities may be offered separately or together, in amounts, at prices and on terms to be determined based on market conditions at the time of offer and set forth in an accompanying shelf prospectus supplement. The net proceeds from the sale of the Securities, if any, are expected to be used to fund ongoing operating requirements, sustaining capital expenditures and development at the Dolores Mine, exploration activities, retirement of debt, potential future acquisitions and for general corporate purposes.

A registration statement relating to these Securities has been filed with the United States Securities and Exchange Commission, but is not yet effective. These Securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This news release does not constitute an offer to sell or the solicitation of an offer to buy, nor will there be any sale of these Securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

A copy of the prospectus included in the U.S. registration statement can be obtained upon request by contacting Investor Relations at the contact information below or electronically at www.sec.gov. A copy of the preliminary short form base prospectus is available electronically at www.sedar.com.
