Argonaut Gold Inc. Announces Intent to Terminate Registration Under U.S. Securities Exchange Act

TORONTO, ONTARIO--(Marketwire - May 20, 2011) -Argonaut Gold Inc. (TSX:AR)("Argonaut" or the "Company") announces today that it will seek to terminate its registration, as successor-registrant to Pediment Gold Corp. ("Pediment"), with the U.S. Securities and Exchange Commission under the U.S. Securities Exchange Act of 1934 ("Exchange Act") as soon as possible by filing a Form 15F with the Commission. As a result of the consummation of the statutory plan of arrangement (the "Arrangement') with Pediment on January 27, 2011, Argonaut is deemed the successor-registrant to Pediment's registration with the U.S. Securities and Exchange Commission under Rule 12g-3(a) of the Exchange Act. Argonaut's common shares, including those issued to Pediment shareholders in the Arrangement, are listed on the Toronto Stock Exchange under the symbol "AR" and are not listed on any national securities exchange in the United States. Argonaut has concluded that it is not in the best interests of its shareholders to retain the U.S. registration at this time.

Upon filing of the Form 15F, Argonaut's continuing reporting obligations under the Exchange Act will be suspended until the termination becomes effective. Once effective, Argonaut expects to receive the exemption from registration provided by Rule 12g3-2(b) under the Exchange Act and will make information available to its securityholders in compliance with that Rule.

Argonaut files reports publicly in Canada as required by Canadian securities regulators and the Toronto Stock Exchange. Argonaut's shareholders may obtain copies of such reports from or from the Company at the contact information listed below. Certain reports are available on Argonaut's website at
