Augusta Closes Increased Red Kite Loan Facility

DENVER, CO, Oct. 5, 2012 /CNW/ - Augusta Resource Corporation (TSX/NYSE MKT: AZC) ("Augusta" or "the Company") is pleased to announce the closing of the previously announced US$83,000,000 loan facility ("Expanded Loan") with RK Mine Finance Trust I ("Red Kite").  The Expanded Loan represents an increase of US$40,000,000 over the previous loan facility with Red Kite.

As previously announced, the terms for the Expanded Loan include interest payable at LIBOR plus 4.50% and a final maturity date of July 21, 2014.  The 1,791,700 Red Kite share purchase warrants were split into two tranches, each with the new exercise price of US$3.85 per share.  The expiry date for 1,374,951 warrants was extended to July 22, 2015 and the expiry date for the remaining 416,749 warrants is unchanged at April 22, 2014.  Since not all of the warrants were extended, the origination fee on the additional loan amount of US$40,000,000 was increased from 2% to 2.2925%.

Rosemont Copper Company ("Rosemont"), a wholly owned subsidiary of Augusta, has also closed the amended Red Kite Copper Concentrates Sales Agreement ("Amended Offtake Agreement") under which Red Kite will purchase 20% of Rosemont's gross annual copper concentrate production until 1,500,000 tonnes has been delivered.

Concurrent with the closing of the Expanded Loan and Amended Offtake Agreement, the Copper Cathode Purchase and Sale Agreement between Rosemont and an affiliate of Red Kite and the US$10,000,000 working capital facility between Augusta and Red Kite were cancelled and deemed null, with no liability to any of the parties.
