Argentex Mining Issues 474,171 Common Shares on Partial Conversion of US$2.3M Convertible Debenture

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Dec 17, 2013) - Argentex Mining Corp. ("Argentex" or the "Company") (TSX VENTURE:ATX)(OTCQB:AGXMF) is pleased to announce the conversion of an additional US$130,000 of the outstanding principal amount of the Convertible Debenture held by Austral Gold Argentina S.A. In the partial conversion, which was effected on December 16, 2013 at a conversion price of US$0.274163 per Unit, Argentex issued 474,171 Units, consisting of 474,171 common shares and 237,086 warrants. Each whole warrant entitles the holder to purchase one additional common share at an exercise price of CDN$0.40 until July 2, 2018.

Details about the Convertible Debenture and the private placement in which it was issued were previously disclosed in a press release dated July 3, 2013.

After adjusting for this partial conversion, the principal balance remaining under the Convertible Debenture is US$390,000 and repayments of US$130,000 are anticipated in January, February and March of 2014. Under the terms of the Convertible Debenture, this amount can be repaid only by conversion into additional Units at the conversion price of US$0.274163 per Unit. These conversions coincide with repayments to Argentex of principal amounts outstanding under a U.S. dollar linked loan intended to minimise currency risk. Loan repayments are made in Argentine pesos in amounts linked to the value of the U.S. dollar at the time of repayment.

None of the securities issued upon the partial conversion have been or will be registered under the United States Securities Act of 1933, as amended (the "Act"), and none of them may be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Act. These securities are "restricted securities" under the Act and are subject to a hold period in the United States of at least six months from the date issued. In addition, these securities are subject to a hold period under applicable Canadian securities laws and the requirements of the TSX Venture Exchange, which will expire on November 3, 2013. Subject to certain exceptions, there are additional restrictions on transfer of these securities described in an Investment Agreement between Argentex and Austral Gold Ltd.. The Investment Agreement, together with all of the other material agreements related to the July 2, 2013 financing, are available on SEDAR at www.sedar.com.
