Superior Production Growth with Fully Un-Hedged Precious Metals Exposure

TORONTO, Aug. 29, 2011 /CNW/ - AuRico Gold Inc. ("AuRico") (TSX:AUQ) (NYSE:AUQ) and Northgate Minerals Corporation ("Northgate") (TSX:NGX) (NYSE-Amex:NXG) are pleased to announce that they have entered into a definitive acquisition agreement (the "Agreement") to create a new leading intermediate gold producer. The new company will have 5 operating gold mines, a sixth mine targeting production in 2012 and 3 gold development projects in Mexico, Canada, and Australia, three of the top global mining jurisdictions. The combined company is completely unhedged and offers full exposure to record gold and silver prices and an exceptional growth profile from approximately 475,000¹ gold equivalent ("Aue") ounces² this year to 730,000+³ Aue ounces in 2013 (growth of approximately 54%). All figures in Canadian dollars, unless otherwise indicated.

Under the terms of the Agreement, AuRico will acquire all of the issued and outstanding common shares of Northgate on the basis of 0.365 AuRico common shares per Northgate common share. Based on both companies' 20-day volume weighted average prices on the Toronto Stock Exchange (TSX) ending on August 26, 2011, the exchange ratio under the offer represents a 45% premium to Northgate's shareholders.

"The combination of AuRico and Northgate will immediately position the combined company as a pre-eminent intermediate gold producer with peer leading growth", said Rene Marion, President and CEO of AuRico. "The assets, projects and people in our two companies are highly complementary and we are excited about the many opportunities ahead for us to continue to deliver value to our shareholders."

Richard Hall, President and CEO of Northgate, added "This transaction gives Northgate shareholders a significant premium to market and an exciting opportunity to participate in a leading intermediate gold company.�  The Northgate team has worked hard to develop a highly successful business in Canada and Australia and we look forward to further value creation through our combination with AuRico."

Transaction Summary:

The acquisition of Northgate by AuRico will be completed by way of a court approved plan of arrangement. The Agreement has been unanimously approved by the Boards of Directors of AuRico and Northgate. UBS Securities Canada Inc. provided a fairness opinion to the Board of Directors of AuRico and GMP Securities L.P.. and Macquarie Capital Markets Canada Ltd. provided fairness opinions to the Special Committee and Board of Directors of Northgate.

The transaction is subject to approval by 66 and 2/3% of the votes cast by holders of Northgate common shares at a special meeting of Northgate shareholders expected to be held in October. The transaction is also subject to obtaining approval by a majority of votes cast by the shareholders of AuRico at a special meeting of AuRico shareholders expected to take place on the same date as the Northgate meeting, as well as certain other customary conditions. Closing of the transaction is expected in October. The Agreement includes customary deal protection and non-solicitation provisions including reciprocal break fees, right to match and fiduciary-out provisions.

On August 28, 2011, the Board of Directors of Northgate determined that AuRico's proposal to enter into the Agreement is a "superior proposal" for the purposes of the arrangement agreement between Northgate and Primero Mining Corp ("Primero") previously announced on July 13, 2011 (the "Primero Agreement").�  Northgate's Board provided notice of that determination to Primero. On receiving this notice, Primero waived its "right to match" the proposal by AuRico. Accordingly, as per the terms of the Primero Agreement, Northgate has paid a termination fee of $25 million to Primero and the Primero Agreement has been terminated.. The meeting of Northgate shareholders currently scheduled for September 21, 2011 has been delayed to a later date which is expected to be in October, 2011, at which Northgate shareholders will be asked to approve the transaction with AuRico.
