Aurico Gold Declares Commercial Production at the Young-Davidson Mine

TORONTO, Sept. 4, 2012 /CNW/ - AuRico Gold Inc. (TSX: AUQ) (NYSE: AUQ), ("AuRico" or "the Company") is pleased to report that its Young-Davidson mine achieved commercial production effective September 1, 2012. Located in Matachewan, Ontario, the Young-Davidson mine is expected to be a key, long lived, strategic asset for AuRico that has potential for significant production and reserve growth.

Commercial production was declared once the mine achieved previously established commissioning thresholds, which included the mill averaging a minimum throughput level of 5,100 tonnes per day, the open pit averaging 29,750 tonnes per day of ore and waste mining, both over a 30-day period, as well as the commissioning of the flotation and gravity circuits.

Recent key operating highlights include:

• The mill facility continued to exceed commissioning threshold levels with four days exceeding 7,000 tonnes per day.
• Gold recoveries steadily increased to targeted levels of approximately 90% following the commissioning of the gravity and flotation circuits and the optimization of the grinding circuit.
• Commissioning of the primary crusher as well as the conveyor system and ore bins is complete, which streamlines the introduction of mill feed into the mill circuit.
• The Company has established a separate 178,000 tonne high-grade stockpile at grades of approximately 1.52 g/t that is in addition to the more than one million tonne stockpile.
• Underground long-hole drilling contractors have been mobilized on site and stope preparation in the Upper Boundary Zone is progressing on schedule. Production from the initial two stopes is expected to begin during the fourth quarter and average approximately 1,000 tonnes per day with grades averaging approximately 3.5 grams per tonne gold.
• Raiseboring of the second leg (450 metres) of the Northgate shaft will start in September and is targeted to reach a vertical depth of 890 metres (9440 level), with a final target of 1,500 vertical metres. The Company anticipates hoisting waste by the second quarter of 2013 and hoisting ore by the third quarter of 2013 once the mid-shaft crushing circuit is commissioned.
• As of August 31, 2012 the Young-Davidson mine reported over 2.3 million hours without a lost time injury.
• A Grand Opening celebration was held at the Young-Davidson mine on August 11 with more than 850 people in attendance including employees and their families, government officials, community leaders and local community members.

"I want to thank all of the employees and contractors who have worked diligently and safely over the past 2 years to achieve this major milestone. In July and August our efforts were focused on process commissioning of the flotation circuits and optimizing the grinding circuit to ensure we had fully stress tested the mill facility prior to declaring commercial production." said Peter MacPhail, Chief Operating Officer, Canada. "During the mill commissioning phase we have intentionally processed lower grade ore while the mill facility was fine-tuned to maximize gold recoveries. With the mill fully commissioned and operating above targeted levels, we have now begun to introduce higher grade ore and expect to see production increase over the coming months."

The production ramp-up at the Young Davidson mine continues to progress well and the operation is expected to be a major driver of AuRico's growth profile going forward. Production growth in 2013 and beyond will be supported by increasing contributions of higher grade ore as the underground mine begins production in the fourth quarter of 2012 and ramps up to targeted levels of up to 8,000 tonnes per day by 2016.
