DENVER, July 10, 2012 /PRNewswire/ - Augusta Resource Corporation (TSX/NYSE MKT: AZC) ("Augusta" or "the Company") is pleased to announce that the ArizonaSuperior Court for Pima County ("Court") has ruled in the Company's favor regarding its appeal of Pima County Air Quality Control District ("Control District") and Pima County Air Quality Hearing Board's ("Hearing Board") denial of Rosemont's Air Permit application. The Court Ruling, dated July 5, 2012, determined that both the Control District and the Hearing Board "acted in an arbitrary and capricious manner and that the [Control District and Hearing Board] abused their discretion." The ruling directed the Control District to process Rosemont's application in a timely manner; moreover, it further supports Rosemont's decision to apply for an Air Permit processed by the Arizona Department of Environmental Quality ("ADEQ"). "This ruling is certainly a positive win for Rosemont," said Rod Pace, Augusta's Chief Operating Officer. "There was no doubt that we were being treated unfairly and uniquely in Pima County. The Court made the right decision to order Pima County to allow Rosemont to be treated justly. Notwithstanding, we will continue to work with the ADEQ to ensure the Rosemont Air Permit gets processed expeditiously."About Augusta Augusta is a base metals company focused on advancing the Rosemont Copper deposit near Tucson, Arizona.
