NOTE TO UNITED STATES READERS-DIFFERENCES IN
UNITED STATES AND CANADIAN REPORTING PRACTICES

The Company is permitted, under the multi-jurisdictional
disclosure system adopted by the United States Securities and Exchange
Commission (the SEC), to prepare this annual report on Form 40-F in accordance
with Canadian disclosure requirements, which differ from those of the United
States. The Company has prepared its financial statements, which are filed as
Exhibit 2to this annual report on Form 40-F, in accordance with Canadian
generally accepted accounting principles (GAAP), and they are subject to
Canadian auditing and auditor independence standards. They are not comparable to
financial statements of United States companies. Significant measurement
differences between Canadian GAAP and United States GAAP are described in Note
18 of the audited consolidated financial statements of the Company. Effective
January 1, 2011, the Company will begin preparing its financial statements in
accordance with International Financial Reporting Standards.

RESOURCE AND RESERVE ESTIMATES

The Companys AIF filed as Exhibit 1to this annual
report on Form 40-F has been prepared in accordance with the requirements of the
securities laws in effect in Canada, which differ from the requirements of
United States securities laws. The terms mineral reserve, proven mineral
reserve and probable mineral reserve are Canadian mining terms as defined in
accordance with Canadian National Instrument 43-101  Standards of Disclosure
for Mineral Projects (NI 43-101) and the Canadian Institute of Mining,
Metallurgy and Petroleum (the CIM) - CIM Definition Standards on Mineral
Resources and Mineral Reserves, adopted by the CIM Council, as amended.
These definitions differ from the definitions in SEC Industry Guide 7 under the
United States Securities Act of 1933, as amended (the Securities Act). Under
SEC Industry Guide 7 standards, a final or bankable feasibility study is
required to report reserves, the three-year historical average price is used in
any reserve or cash flow analysis to designate reserves and the primary
environmental analysis or report must be filed with the appropriate governmental
authority.

In addition, the terms mineral resource, measured mineral
resource, indicated mineral resource and inferred mineral resource are
defined in and required to be disclosed by NI 43-101; however, these terms are
not defined terms under SEC Industry Guide 7 and are normally not permitted to
be used in reports and registration statements filed with the SEC. Investors are
cautioned not to assume that any part or all of mineral deposits in these
categories will ever be converted into reserves. Inferred mineral resources
have a great amount of uncertainty as to their existence, and great uncertainty
as to their economic and legal feasibility. It cannot be assumed 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 pre-feasibility studies, except in rare cases. Investors
are cautioned not to assume that all or any part of an inferred mineral resource
exists or is economically or legally mineable. Disclosure of contained ounces
in a resource is permitted disclosure under Canadian regulations; however, the
SEC normally only permits issuers to report mineralization that does not
constitute reserves by SEC Industry Guide 7 standards as in place tonnage and
grade without reference to unit measures.

Accordingly, information contained in this annual report on
Form 40-F and the documents incorporated by reference herein contain
descriptions of the Companys mineral deposits that may not be comparable to
similar information made public by U.S. companies subject to the reporting and
disclosure requirements under the United States federal securities laws and the
rules and regulations thereunder.

CURRENCY

Unless otherwise indicated, all dollar amounts in this annual
report on Form 40-F are in United States dollars. The exchange rate of Canadian
dollars into United States dollars, on December 31, 2010, based upon the noon
rate of exchange as quoted by the Bank of Canada, was U.S.$1.00 =
Cdn.$0.9946.

ANNUAL INFORMATION FORM

The Companys AIF for the fiscal year ended December 31, 2010
is filed as Exhibit 1and incorporated by reference in this annual report
on Form 40-F.

AUDITED ANNUAL FINANCIAL STATEMENTS

The audited consolidated financial statements of the Company
for the years ended December 31, 2010, 2009 and 2008, including the report of
the independent auditor with respect thereto, are filed as Exhibit 2and
incorporated by reference in this annual report on Form 40-F. For a
reconciliation of material measurement differences between Canadian and United
States GAAP, see Note 18 to the Companys audited consolidated financial
statements.

MANAGEMENTS DISCUSSION AND ANALYSIS

The Companys managements discussion and analysis (MD&A)
is filed as Exhibit 3and incorporated by reference in this annual report
on Form 40-F.

TAX MATTERS

Purchasing, holding, or disposing of securities of the Company
may have tax consequences under the laws of the United States and Canada that
are not described in this annual report on Form 40-F. Holders of the Companys
common shares should consult their own tax advisors regarding the tax
consequences of purchasing, holding, or disposing of securities of the
Company.

U.S. holders of the Companys common shares should be aware
that the Company believes it was classified as a passive foreign investment
company ("PFIC") during the tax year ended December 31, 2010, and based on
current business plans and financial expectations, the Company expects that it
will be a PFIC for the current tax year.

If the Company is a PFIC for any year during a U.S.
shareholders holding period, then such U.S. shareholder generally will be
required to treat any gain realized upon a disposition of the Companys common
shares, or any so-called excess distribution received on the Companys common
shares, as ordinary income, and to pay an interest charge on a portion of such
gain or distributions, unless the shareholder makes a timely and effective
"qualified electing fund" ("QEF") election or a "mark-to-market" election with
respect to the Companys common shares. A U.S. shareholder who makes a QEF
election generally must report on a current basis its share of the Company's net
capital gain and ordinary earnings for any year in which the Company is a PFIC,
whether or not the Company distributes any amounts to its shareholders.  The Company will make available
the PFIC annual information statement as provided pursuant to Treasury
Regulation section 1.1295 -1 (g) (1) on its website at
www.augustaresource.com. A U.S.
shareholder who makes the mark-to-market election generally must include as
ordinary income each year the excess of the fair market value of the Companys
common shares over the taxpayers basis therein.

Each U.S. shareholder should consult its own tax advisor
regarding the PFIC rules and the U.S. federal income tax consequences of the
acquisition, ownership, and disposition of the Companys common shares.

CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

At the end of the period covered by this annual report on Form
40-F for the fiscal year ended December 31, 2010, an evaluation was carried out
under the supervision of, and the with the participation of, the Companys
management, including its Chief Executive Officer (CEO) and Chief Financial
Officer (CFO), of the effectiveness of the design and operation of the
Companys disclosure controls and procedures (as defined in Rule 13a-15(e) of
the Exchange Act).

3

---

Based upon that evaluation, the Companys CEO and CFO have
concluded that the disclosure controls and procedures were effective to give
reasonable assurance that the information required to be disclosed by the
Company in reports that it files or submits under the Exchange Act is (i)
recorded, processed, summarized and reported, within the time periods specified
in the SECs rules and forms, and (ii) accumulated and communicated to
management, including its principal executive and principal financial officers,
or persons performing similar functions, as appropriate to allow timely
decisions regarding required disclosure.

Managements Report on Internal Control over Financial
Reporting

Management is responsible for establishing and maintaining
adequate internal control over financial reporting, as defined in Rules
13a-15(f) under the Exchange Act. 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 (i) pertain to the maintenance of records
that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (ii) 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 (iii) 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. It should be noted that a control
system, no matter how well conceived or operated, can only provide reasonable
assurance, not absolute assurance, that the objectives of the control system are
met. 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 policies and procedures may
deteriorate.

Management, including the CEO and CFO, assessed the
effectiveness of the Companys internal control over financial reporting as of
December 31, 2010. In making this assessment, management used the criteria set
forth in the Internal Control Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). Based on its
assessment, management has concluded that, as of December 31, 2010, the
Companys internal control over financial reporting was effective and no
material weaknesses in the Companys internal control over financial reporting
were discovered.

The Company is required to provide an auditors attestation
report on its internal control over financial reporting for the fiscal year
ended December 31, 2010. In this annual report on Form 40-F, the Companys
independent registered auditor, Ernst & Young LLP, must state its opinion as
to the effectiveness of the Companys internal control over financial reporting
for the fiscal year ended December 31, 2010. Ernst & Young LLP has audited
the Companys financial statements included in this annual report on Form 40-F
and has issued an attestation report on the Companys internal control over
financial reporting.

Auditors Attestation Report

Ernst & Youngs attestation report on the Companys
internal control over financial reporting is attached as Exhibit 4to
this annual report on Form 40-F and is incorporated by reference herein.

responsible for the Companys corporate governance and has a separately

Committee Charter may be found on the Companys website at www.augustaresource.com.

Committee established in accordance with Section 3(a)(58)(A) of the Exchange
Act. The Companys Audit Committee is composed of Michael A. Steeves, W. Durand
Eppler and Robert P. Wares, all of whom, in the opinion of the directors, are
independent (as determined under Rule 10A-3 of the Exchange Act and Section 803A
of the NYSE Amex Company Guide) and are financially literate. Please refer to
the Companys AIF attached as Exhibit 1to this annual report on Form
40-F for details in connection with each of these members and their

and the Companys independent auditors to review and inquire into matters
affecting financial reporting, the system of internal accounting and financial
controls, as well as audit procedures and audit plans. The Audit Committee also
recommends to the Board of Directors which independent registered public
auditing firm should be appointed by the Company. In addition, the Audit
Committee reviews and recommends to the Board of Directors for approval the
annual financial statements, the MD&A, and undertakes other activities
required by exchanges on which the Companys securities are listed and by
regulatory authorities to which the Company is held responsible.

The full text of the Audit Committee Charter is attached as
Appendix 1 to the Companys AIF, attached hereto as Exhibit 1, and is
incorporated by reference in this annual report on Form 40-F.

Audit Committee Financial Expert

The Companys Board of Directors has determined that Michael A.
Steeves qualifies as a financial expert (as defined in Item 407(d)(5)(ii) of
Regulation S-K under the Exchange Act), is financially sophisticated as
determined in accordance with Section 803B(2)(iii), and is independent (as

Company Guide).

NOTICES PURSUANT TO REGULATION BTR

There were no notices required by Rule 104 of Regulation BTR
that the Company sent during the year ended December 31, 2010 concerning any
equity security subject to a blackout period under Rule 101 of Regulation
BTR.

NYSE AMEX CORPORATE GOVERNANCE

The Companys common shares are listed on the NYSE Amex.
Section 110 of the NYSE Amex Company Guide permits the NYSE Amex to consider the
laws, customs and practices of foreign issuers in relaxing certain NYSE Amex
listing criteria, and to grant exemptions from NYSE Amex listing criteria based
on these considerations. A company seeking relief under these provisions is
required to provide written certification from independent local counsel that
the non-complying practice is not prohibited by home country law. A description
of the significant ways in which the Companys governance practices differ from
those followed by domestic companies pursuant to NYSE Amex standards is as
follows:

Shareholder Meeting Quorum
Requirement: The NYSE Amex minimum quorum requirement for a shareholder
meeting is one-third of the outstanding shares of common stock. In addition, a
company listed on the NYSE Amex is required to state its quorum requirement in
its bylaws. The Companys quorum requirement is set forth in its Memorandum and
Articles. A quorum for a meeting of members of the Company is two persons who
are, or who represent by proxy, shareholders who, in the aggregate, hold at
least 5% of the shares entitled to be voted at the meeting.

Proxy Delivery Requirement: The
NYSE Amex requires the solicitation of proxies and delivery of proxy statements
for all shareholder meetings, and requires that these proxies shall be solicited
pursuant to a proxy statement that conforms to SEC proxy rules. The Company is a
foreign private issuer as defined in Rule 3b-4 under the Exchange Act, and the
equity securities of the Company are accordingly exempt from the proxy rules set
forth in Sections 14(a), 14(b), 14(c) and 14(f) of the Exchange Act. The Company
solicits proxies in accordance with applicable rules and regulations in
Canada.

The foregoing are consistent with the laws, customs and
practices in Canada.

In addition, the Company may from time-to-time seek relief from
NYSE Amex corporate governance requirements on specific transactions under
Section 110 of the NYSE Amex Company Guide by providing written certification
from independent local counsel that the non-complying practice is not prohibited
by our home country law, in which case, the Company shall make the disclosure of
such transactions available on its website at www.augustaresource.com.
Information contained on the Companys website is not part of this annual report
on Form 40-F.

MINE SAFETY DISCLOSURE

Pursuant to Section 1503(a) of the recently enacted Dodd-Frank
Wall Street Reform and Consumer Protection Act of 2010 (the Dodd-Frank Act),
issuers that are operators (or that have operations), or that have a subsidiary
that is an operator (or that has operations), of a coal or other mine in the
United States are required to disclose in their periodic reports filed with the
SEC information regarding specified health and safety violations, orders and
citations, related assessments and legal actions, and mining-related fatalities.
During the fiscal year ended December 31, 2010, the Company had no such
specified health and safety violations, orders or citations, related assessments
or legal actions, mining-related fatalities, or similar events in relation to
the Companys United States operations requiring disclosure pursuant to Section
1503(a) of the Dodd-Frank Act.

UNDERTAKING

The Company undertakes to make available, in person or by
telephone, representatives to respond to inquiries made by the Commission staff,
and to furnish promptly, when requested to do so by the Commission staff,
information relating to: the securities registered pursuant to Form 40-F; the
securities in relation to which the obligation to file an annual report on Form
40-F arises; or transactions in said securities.

CONSENT TO SERVICE OF PROCESS

The Company previously filed an Appointment of Agent for
Service of Process and Undertaking on Form F-X with the SEC on July 14, 2006,
with respect to the class of securities in relation to which the obligation to
file this annual report on Form 40-F arises.
