Reserve Highlights

As at December 31, 2013, the Company is reporting:

  • Proven and Probable Mineral Gold Reserves of 6.5 million gold ounces, a 0.29 million ounce decrease from 2012, primarily related to depletion in the El Chanate and Young-Davidson open pits.
  • At the Young-Davidson mine underground reserves increased by 1%, with grades remaining consistent with 2012, while overall reserves decreased by 3%, primarily due to depletion in the open pit.
  • Reserves decreased by 15% at the El Chanate mine, primarily related to depletion, while reserve grades increased by 5%.

Gold Reserves by asset are summarized in the table below:

In addition to gold reserves, the Company is also reporting copper reserves of:

  • 619 million pounds at the Kemess Underground Project at a reserve grade of 0.28%, using a copper price of $3.00 per pound.

"The Company remained focused on improving the quality of our reserve base by using more conservative metal price assumptions at our operating assets to ensure our reserve base is comprised of quality, high margin ounces," stated Scott Perry, President and Chief Executive Officer. He continued, "We are particularly encouraged with reserves reported from the Young-Davidson underground mine, which remained consistent with the prior year, even when using a conservative $1,250 per ounce gold price assumption. This demonstrates the quality of the Young-Davidson underground ore body and provides further confirmation of this robust deposit for low cost, long life, ounces."

As at December 31, 2013 the Company is also reporting the following mineral resources, which are in addition to reserves:

  • Measured and Indicated gold resources of 2.5 million gold ounces, at a grade of 0.88 g/t; and
  • Inferred gold resources of 0.5 million gold ounces, at a grade of 1.02 g/t.

  • Kemess Underground assumed a gold price of $1,300 per ounce, a silver price of $23.00 per ounce for silver, and a copper price of $3.00 per pound for reserves. Kemess assumed a $13.00 NSR cutoff for resources.
  • Orion assumed a gold price of $850 per ounce and a silver price of $13.00 per ounce for resources.
  • Mineral Reserves assume the following cutoff grades and process recoveries:
    • Young-Davidson - Surface: 0.50 gpt cutoff, 91% mill recovery

    • El Chanate: 0.15 gpt cutoff, 30%-65% leach recovery
    • Kemess Underground: $15 NSR cutoff, mill recovery of 72% for gold and 91% for copper
  • Reserves have been reported in accordance with NI 43-101, as required by Canadian securities regulatory authorities. In addition, while the terms "Measured", "Indicated and "Inferred" Mineral Resources are required pursuant to NI 43-101, the SEC does not recognize such terms. Canadian standards differ significantly from the requirements of the SEC, and mineral resource information contained herein is not comparable to similar information regarding mineral reserves disclosed in accordance with the requirements of the SEC. Investors should understand that "Inferred" Mineral Resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. In addition, investors are cautioned not to assume that any part or all of AuRico's Mineral Resources constitute or will be converted into Reserves.
  • Orion Mineral Resources are reflected on a 50% basis.  Following the completion of a joint venture agreement, Minera Frisco, S.A.B. de C.V. will have a 50% interest in the Orion project.
  • Mineral Reserve and Resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
  • Mineral Resources were prepared under the supervision of Jeffrey Volk, CPG, FAusIMM, the Director of Reserves and Resources, for AuRico Gold Inc.

Cautionary Note to U.S. Investors Concerning Measured, Indicated and Inferred Resources
This press release uses the terms "measured," "indicated" and "inferred" resources. We advise investors that while those terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize them. "Inferred" resources" have a great amount of uncertainty as to their existence and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. United States investors are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable.
