REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of AuRico Gold Inc.

We have audited AuRico Gold Inc.s internal control over
financial reporting as of December 31, 2012, based on criteria established inInternal Control  Integrated Frameworkissued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). AuRico Gold Inc.s
management is responsible for maintaining effective internal control over
financial reporting and for its assessment of the effectiveness of internal
control over financial reporting, included in the managements discussion and
analysis included in this Annual Report on Form 40-F. Our responsibility is to
express an opinion on the Companys internal control over financial reporting
based on our audit.

We conducted our audit in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards
require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in
all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness
exists, and testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk. Our audit also included performing
such other procedures as we considered necessary in the circumstances. We
believe that our audit provides a reasonable basis for our opinion.

A companys internal control over financial reporting is a
process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles. A
companys internal control over financial reporting includes those policies and
procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) provide reasonable assurance that transactions are
recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and
expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the companys assets that could have a
material effect on the financial statements.

Because of its inherent limitations, internal control over
financial reporting may not prevent or detect misstatements. Also, projections
of any evaluation of effectiveness to future periods are subject to the risk
that controls may become inadequate because of changes in conditions, or that
the degree of compliance with the policies or procedures may deteriorate.

In our opinion, AuRico Gold Inc. maintained, in all material
respects, effective internal control over financial reporting as of December 31,
2012, based on criteria established in Internal Control  Integrated
Frameworkissued by the Committee of Sponsoring Organizations of the
Treadway Commission (COSO).
