DENVER, Aug. 6, 2012 /PRNewswire/ - Augusta Resource Corporation (TSX/NYSE MKT: AZC) ("Augusta" or "the Company") is pleased to announce that the Arizona Department of Environmental Quality ("ADEQ") has asserted complete jurisdiction over Rosemont Copper's ("Rosemont") Air Quality Permit due to the confusion and uncertainty caused by the inappropriate denial of Rosemont's Air Quality Permit application by the Pima County Department of Environmental Quality. Rosemont has thereby received the draft Air Quality Permit from the ADEQ. ADEQ's Air Quality Permit will ensure that Rosemont meets all federal, state and local requirements by operating with enhanced emissions controls at the mine site. The public comment period, which commences today, will be 60 days and will end on October 9, 2012. Soon after the conclusion of the public comment period, the final Air Quality Permit will be issued for Rosemont. "We are happy to see the Air Quality Permit process continue to advance and have the ADEQ officially issue the draft permit," said Rod Pace, Augusta's Chief Operating Officer. "The ADEQ will give Rosemont regulatory certainty and specific timeframes that were lacking in the Pima County permitting process. The ADEQ has handled our application since the initial submission in November 2011 in a professional and consistent manner."
