Toronto, ON, August 20, 2007 - Further to their joint news releases dated March 5^th and July 18, 2007, Aurogin Resources Ltd. ("Aurogin") (TSX-V: AUQ) and Morgain Minerals Inc. ("Morgain") (TSX-V: MGM) are pleased to announce that  their shareholders have voted overwhelmingly to approve the amalgamation of the companies under the terms and conditions contained in the Joint Information Circular dated July 18, 2007, and to adopt the Board recommended stock option plan.  At a meeting of Aurogin shareholders held Friday, August 17, 2007, the amalgamation was approved by 97% of the votes cast representing 43% of Aurogin's outstanding shares.  At a meeting of Morgain shareholders held later that day, the amalgamation was approved by 99% of the votes cast representing 30% of Morgain's outstanding shares.  The TSX Venture Exchange (the "TSX-V") has conditionally accepted the amalgamation.

The amalgamation is expected to close on or before August 29, 2007 and will create a new corporation, Castle Gold Corporation ("Castle Gold"),  which subject to final acceptance by the TSX-V, will begin trading in approximately 7 to 10 days under the trading symbol "CSG".  Shareholders of Aurogin will receive one (1) common share of Castle Gold for each two (2) Aurogin shares held immediately prior to the date on which the transaction becomes effective, and shareholders of Morgain will also receive one (1) common share of Castle Gold for each two (2) Morgain common shares held.  Upon completion of the amalgamation, shareholders of Aurogin and Morgain will received a Letter of Transmittal setting out the procedure to be followed in order to exchange their share certificates for certificates representing shares of Castle Gold.

"This marks an historic moment for Aurogin and Morgain shareholders.  Their overwhelming support ushers in the creation of a new gold producer, ultimately aimed at filling a growing void in the intermediate producer sector," said Christopher E. Babcock, soon to be President and CEO of Castle Gold.  "Our organization will have increased reserves and resources, geographical synergies, a stronger mine-building team and a management team committed to focusing its efforts on growing shareholder value in both the near- and long-term."     

"The unquestionable support from the shareholders of both companies clearly demonstrates their enthusiasm towards the creation of Castle Gold," said John H. Paterson, President and CEO of Aurogin.  "Aurogin shareholders are gaining access to both a tremendous team at Morgain and to an excellent asset with a 12 year mine life at El Castillo."  

Castle Gold will jointly operate and own 50% of the El Sastre gold mine in Guatamala and operate the 100% owned El Castillo gold mine in Mexico.  In addition, Castle Gold will continue work on the La Fortuna property in Mexico with the goal of producing a National Instrument 43-101 compliant resource aimed at advancing the property towards production.  Work will also continue on various other mining properties with the goal of increasing resources and creating additional shareholder value.
