FORWARD-LOOKING INFORMATION

Certain statements and information contained in this annual
report on Form 40-F (the Form 40-F) and the documents incorporated by
reference in this Form 40-F constitute "forward-looking statements" within the
meaning of applicable U.S. securities laws and forward-looking information
within the meaning of applicable Canadian securities laws, which we refer to
collectively as "forward-looking statements". Forward-looking statements are
statements and information regarding possible events, conditions or results of
operations that are based upon assumptions about future economic conditions and
courses of action. All statements and information other than statements of
historical fact may be forward-looking statements. In some cases,
forward-looking statements can be identified by the use of words such as seek,
expect, anticipate, budget, plan, estimate, continue, forecast,
intend, believe, predict, potential, target, may, could, would,
might, will and similar words or phrases (including negative variations)
suggesting future outcomes or statements regarding an outlook. Forward-looking
statements in this Form 40-F and the documents incorporated herein by reference
include, but are not limited to statements and information regarding: the
Company's future mining activities, including mining capacity, recoveries, cash
costs, production and mine life; the Company's reserves and resources estimates;
the Companys exploration and development plans, including anticipated costs and
timing thereof; the Companys plans for growth through exploration activities,
acquisitions or otherwise; and expectations regarding future maintenance and
capital expenditures, working capital requirements, the availability of
financing and future effective tax rates.

Such forward-looking statements are based on a number of
material factors and assumptions, including, but not limited to: that contracted
parties provide goods and/or services in a timely manner, that no unusual
geological or technical problems occur; that plant and equipment function as
anticipated and that there is no material adverse change in the price of gold,
costs associated with production or recoveries.

Forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause actual results, performance or
achievements, or industry results, to differ materially from those anticipated
in such forward-looking statements. The Company believes the expectations
reflected in such forward-looking statements are reasonable, but no assurance
can be given that these expectations will prove to be correct and you are
cautioned not to place undue reliance on forward-looking statements contained
herein. Some of the risks and other factors which could cause actual results to
differ materially from those expressed in the forward-looking statements
contained in this Form 40-F and the documents incorporated herein by reference
include, but are not limited to: risks and uncertainties relating to the
interpretation of drill results, the geology, grade and continuity of mineral
deposits and conclusions of economic evaluations; results of initial
feasibility, pre-feasibility and feasibility studies, and the possibility that
future exploration, development or mining results will not be consistent with
the Companys expectations; risks relating to possible variations in reserves,
resources, grade, planned mining dilution and ore loss, or recovery rates and
changes in project parameters as plans continue to be refined; mining and
development risks, including risks related to accidents, equipment breakdowns,
labour disputes (including work stoppages and strikes) or other unanticipated
difficulties with or interruptions in exploration and development; the potential
for delays in exploration or development activities or the completion of
feasibility studies; risks related to the inherent uncertainty of production and
cost estimates and the potential for unexpected costs and expenses; risks
related to commodity price and foreign exchange rate fluctuations; the uncertainty of
profitability based upon the cyclical nature of the industry in which the
Company operates; risks related to failure to obtain adequate financing on a
timely basis and on acceptable terms or delays in obtaining governmental
approvals or in the completion of development or construction activities; risks
related to environmental regulation and liability; political and regulatory
risks associated with mining and exploration; risks related to the uncertain
global economic environment; and other factors contained in the section entitled
Risk Factors in our Annual Information Form included as Exhibit 99.1 hereto
(the Annual Information Form).

---

Although the Company has attempted to identify important
factors that could cause actual results or events to differ materially from
those described in the forward-looking statements, you are cautioned that this
list is not exhaustive and there may be other factors that the Company has not
identified. Furthermore, the Company undertakes no obligation to update or
revise any forward-looking statements included in, or incorporated by reference
in, this Form 40-F if these beliefs, estimates and opinions or other
circumstances should change, except as otherwise required by applicable law.

CAUTIONARY NOTE REGARDING MINERAL RESERVE AND RESOURCE
ESTIMATES

The Company is subject to the reporting requirements of the
applicable Canadian securities laws, and as a result we report our mineral
reserves and resources according to Canadian standards. Canadian reporting
requirements for disclosure of mineral properties are governed by National
Instrument 43-101 Standards of Disclosure for Mineral Projects (NI
43-101). The definitions of NI 43-101 are adopted from those given by the
Canadian Institute of Mining, Metallurgy and Petroleum. U.S. reporting
requirements are governed by Industry Guide 7 (Guide 7) of the Securities and
Exchange Commission (the Commission). These reporting standards have similar
goals in terms of conveying an appropriate level of confidence in the
disclosures being reported, but embody different approaches and definitions. For
example, under Industry Guide 7, mineralization may not be classified as a
reserve unless the determination has been made that the mineralization could
be economically and legally produced or extracted at the time the reserve
determination is made. In particular, we report resources in accordance with
NI 43-101. While the terms Mineral Resource, Measured Mineral Resource,
Indicated Mineral Resource and Inferred Mineral Resource are recognized and
required by Canadian regulations, they are not defined terms under standards of
the Commission and generally, U.S. companies are not permitted to report
resources in documents filed with the Commission. As such, certain information
contained in this Form 40-F concerning descriptions of mineralization and
resources under Canadian standards is not comparable to similar information made
public by U.S. companies subject to the reporting and disclosure requirements of
the Commission. In addition, an Inferred Mineral Resource has a great amount of
uncertainty as to its existence and as to its economic and legal feasibility,
and you cannot assume that all or any part of an Inferred Mineral 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. You are cautioned not to assume that all or any part of
Measured or Indicated Resources will ever be converted into Mineral Reserves,
and not to assume that all or any part of an Inferred Mineral Resource exists,
or is economically or legally mineable. In addition, the definitions of Proven
Mineral Reserves and Probable Mineral Reserves under CIM standards differ in
certain respects from the standards of the Commission.

DISCLOSURE CONTROLS AND PROCEDURES

Disclosure controls and procedures are controls and procedures
designed to ensure that (i) information required to be disclosed by the Company
in reports that it files or submits to the Commission under the Exchange Act of
1934, as amended (the Exchange Act), is recorded, processed, summarized and
reported within the time periods specified in the Commissions rules and forms
and (ii) information required to be disclosed in the Companys reports filed
under the Exchange Act is accumulated and communicated to the Companys
management, including its Chief Executive Officer (CEO) and Chief Financial
Officer (CFO), as appropriate, to allow for timely decisions regarding
required disclosure.

At the end of the period covered by this report, an evaluation
was carried out under the supervision of and with the participation of the
Companys management, including the CEO and CFO, of the effectiveness of the
design and operations of the Companys disclosure controls and procedures. The
evaluation included documentation review, enquiries and other procedures
considered by management to be appropriate in the circumstances. Based on that
evaluation, the Companys CEO and CFO have concluded that, as of the end of the
period covered by this report, the Companys disclosure controls and procedures
were effective.

The Companys management, including the CEO and CFO, does not
expect that its disclosure controls and procedures or internal controls and
procedures will prevent all error and all fraud. A control system, no matter how
well conceived and operated, can provide only reasonable, not absolute,
assurance that the objectives of the control system are met. Further, the design
of a control system must reflect the fact that there are resource constraints,
and the benefits of controls must be considered relative to their costs. Because
of the inherent limitations in all control systems, no evaluation of controls
can provide absolute assurance that all control issues and instances of fraud,
if any, within the Company have been detected. These inherentlimitations
include the realities that judgments in decision-making can be faulty, and that
breakdowns can occur because of simple error or mistake. Additionally, controls
can be circumvented by the individual acts of some persons, by collusion of two
or more people, or by management override of the control. The design of any
system of controls also is based in part upon certain assumptions about the
likelihood of future events, and there can be no assurance that any design will
succeed in achieving its stated goals under all potential future conditions;
over time, control may become inadequate because of changes in conditions, or
the degree of compliance with the policies or procedures may deteriorate.
Because of the inherent limitations in a cost-effective control system,
misstatements due to error or fraud may occur and not be detected.

INTERNAL CONTROL OVER FINANCIAL REPORTING

Managements annual report on internal control over
financial reporting.The Companys management is responsible for
establishing and maintaining adequate internal control over financial reporting
as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The
Companys internal control over financial reporting is a process designed to
provide reasonable assurance regarding the reliability of the Companys
financial reporting and the preparation of financial statements for external
purposes in accordance with International Financial Reporting Standards as
issued by the International Accounting Standards Board.

---

Management assessed the effectiveness of the Companys internal
control over financial reporting as of December 31, 2012 based on the criteria
set forth in Internal Control  Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission. Based on this evaluation,
management has concluded that the Companys internal control over financial
reporting was effective as of December 31, 2012.

Attestation report of the registered public accounting firm.Pursuant to section 404(b) of the Sarbanes-Oxley Act of 2002, as amended by
section 103 of the Jumpstart Our Business Startups Act,the Company is
not required to include an auditor attestation report in this annual report on
Form 40-F.

Changes in internal control over financial reporting.During the period covered by this annual report on Form 40-F, no change
occurred in the Companys internal control over financial reporting that has
materially affected, or is reasonably likely to materially affect, the Companys
internal control over financial reporting.

NOTICES PURSUANT TO REGULATION BTR

The Company was not required by Rule 104 of Regulation BTR to
send any notices to any of its directors or executive officers during the year
ended December 31, 2012.

AUDIT COMMITTEE FINANCIAL EXPERT

The Companys board of directors (the Board) has determined
that it has at least one audit committee financial expert serving on its audit
committee. The Board has determined that Paula Rogers is an audit committee
financial expert (as such term is defined in paragraph 8(b) of General
Instruction B to Form 40-F) and is independent, as that term is defined by the
Exchange Act and the NYSE MKTs corporate governance standards applicable to the
Company.

The Commission has indicated that the designation of a person
as an audit committee financial expert does not make such person an expert for
any purpose, including without limitations for purpose of Section 11 of the
Securities Act of 1933, does not impose on such person any duties, obligations
or liability that are greater than those imposed on such person as a member of
the audit committee and the Board in the absence of such designation and does
not affect the duties, obligations or liability of any other member of the audit
committee or Board.

CODE OF ETHICS

The Board has adopted a written code of ethics entitled, Code
of Business Conduct (the Code), by which it and all officers and employees of
the Company, including the Companys principal executive officer, principal
financial officer, principal accounting officer or controller, abide. There were
no amendments, or waivers granted in respect of, the Code during the year ended
December 31, 2012. The Code is posted on the Companys website at www.timminsgold.com. A copy of the Code may also be
obtained by contacting the Corporate Secretary of the Company at the address or
telephone number indicated on the cover page of this annual report on Form 40-F.
If there is an amendment to the Code, or if a waiver of the Code is granted to
any of Companys principal executive officer, principal financial officer,
principal accounting officer or controller, the Company intends to disclose any such amendment or waiver by posting
such information on the Companys website. Unless and to the extent specifically
referred to herein, the information on the Companys website shall not be deemed
to be incorporated by reference in this annual report on Form 40-F.
