AUGUSTA RESOURCE APPOINTS ROBERT P. PIROOZ TO ITS BOARD OF DIRECTORS

Robert Pirooz has joined Augusta Resource Corp.'s board of directors, effective Nov. 9, 2012.

Mr. Pirooz has over 20 years of legal experience focused in the mining sector, with a particular strength in strategic transactions. He is currently general counsel and director of Pan American Silver Corp.

His previous experience includes being group vice-president, general counsel, for the BCR group of companies and corporate and commercial solicitor for several law firms. Mr. Pirooz was called to the British Columbia bar in 1990 after obtaining a juris doctor degree from the University of British Columbia and studying commerce at Dalhousie University. Mr. Pirooz is also chairman of Lumina Copper Corp. and director and secretary of Anfield Nickel Corp.

Richard Warke, Augusta's executive chairman, commented: "Robert's extensive legal background adds great value to our board. His experience in mining and strategic transactions supplements the existing skills of our directors. We believe his expertise will contribute considerably to Augusta as we advance the Rosemont copper project into construction early next year and become one step closer to achieving our objective of becoming a solid mid-tier copper producer. On behalf of the board of directors, we welcome him to the team."

The company also announces the resignation of Donald Clark from the board of directors; however, he will continue to have an advisory role to Augusta on a consultative basis. Mr. Clark has been a valued member of the board since the inception of the company. Augusta would like to thank him for his commitment to the company and wishes him the best in his future endeavours.

The board of directors is now composed of Timothy Baker, John Brodie, Gil Clausen (president and chief executive officer), Durand Eppler, Christopher Jennings (lead director), Robert Pirooz, Robert Wares and Richard Warke (executive chairman).
