PRELIMINARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

The information presented or incorporated by reference in this Annual Report on Form 40-F contains both historical and prospective statements concerning Minera Andes
Inc. and its operations. Historical statements are based on events that have already happened; examples include the reported financial and operating results, descriptions of pending and completed transactions, and management and compensation
matters. Prospective statements, on the other hand, are based on events that are reasonably expected to happen in the future; examples include the timing of projected operations, the likely effect or resolution of known contingencies or other
foreseeable events, and projected operating results. In this Annual Report, Minera Andes Inc. is referred to as Minera Andes, we, our, and the Company.

Prospective statements (which are known as forward-looking statements under the Private Securities Litigation Reform Act of 1995) may or may not prove
true with the passage of time because of future risks and uncertainties. Significant financial, operational, governmental and regulation, and market risks are described in the Managements Discussion and Analysis.

NOTE TO UNITED STATES READERS-

DIFFERENCES IN UNITED STATES AND CANADIAN REPORTING PRACTICES

The Company is permitted, under a multi-jurisdictional disclosure system,
adopted by the United States Securities Exchange Commission (the SEC), to prepare this Annual Report on Form 40-F in accordance with Canadian disclosure requirements, which are different from those of the United States. The Company
prepares its consolidated financial statements, which are filed with this report on Form 40-F in accordance with Canadian generally accepted accounting practices (GAAP), and they may be subject to Canadian auditing and auditor
independence standards. They may not be comparable to consolidated financial statements of the United States companies. Significant differences between Canadian GAAP and United States GAAP are described in Note 13 of the comparative audited
consolidated financial statements of the Company.

RESOURCE AND RESERVE ESTIMATES

The terms Mineral Reserve, Proven Mineral Reserve and Probable Mineral Reserve are Canadian mining terms as defined in accordance
with 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 may be amended from time to time by the CIM. These definitions differ from the definitions in the United States Securities & Exchange Commission (SEC) Industry
Guide 7 under the Securities Act of 1933. Under SEC Guide 7 standards, a Final or Bankable feasibility study is required to report reserves, the three year history 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 normally are 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.

Accordingly, information contained in this report and the documents incorporated by reference herein containing descriptions of our mineral deposits 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.

EVALUATION OF CONTROLS AND PROCEDURES

The Company maintains disclosure controls and procedures as defined in Rules
13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act) that are designed to ensure that information required to be disclosed in its reports filed or submitted under the Exchange Act is processed,
recorded, summarized and reported within the time periods specified in the SECs rules and forms, and that such information is accumulated and communicated to the Companys management, including the Companys Chief Executive Officer
and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well
designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of management, including the
Companys Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Companys disclosure controls and procedures as of the end of the period covered by this Annual Report. Based on this
evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the Companys internal control over financial reporting were not effective as of December 31, 2007, at the reasonable assurance level, because of the
material weaknesses described in Managements Report on Internal Control over Financial Reporting.

Notwithstanding the existence of the
material weaknesses described below, management has concluded that the consolidated financial statements in this Form 40-F fairly present, in all material respects, the Companys financial position, results of operations and cash flows for the
periods presented.

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(d), and 15d-15(f) under the
Exchange Act. The Companys management has employed a framework consistent with the Exchange Act Rule 13a-15(c) to evaluate the Companys internal control over financial reporting. The Companys internal control over financial
reporting is designed to provide reasonable assurance regarding the preparation and fair presentation of published consolidated financial statements in accordance with Canadian Generally Accepted Accounting Principles (Canadian GAAP), including a
reconciliation of net loss to US Generally Accepted Accounting Principles (US GAAP).

The Companys internal control over financial reporting includes
those policies and procedures that (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company (b) provide reasonable assurance that
transactions are recorded as necessary to permit preparation of consolidated financial statements in accordance with Canadian 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 (c) 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 consolidated financial statements.

Internal controls over financial reporting, no matter how well designed, have inherent
limitations. Therefore, internal control over financial reporting determined to be effective can provide only reasonable assurance with respect to financial statement preparation and may not prevent or detect all misstatements. Moreover, 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.

Management performed an assessment of the effectiveness of the Companys internal control over financial reporting as of December 31, 2007, based on the
criteria set forth in the Internal Control  Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The objective of this assessment was to determine whether the
Companys internal control over financial reporting was effective as of December 31, 2007.

A material weakness, as defined by Securities
Exchange Commission rules, is a significant deficiency, or combination of significant deficiencies, such that there is a reasonable possibility that material misstatement of the annual or interim consolidated financial statements will not be
prevented or detected. In its assessment of the effectiveness of internal control over financial reporting as of December 31, 2007, management determined that there were control deficiencies that constituted material weaknesses, as described
below.

The Company does not have sufficient personnel with the skills and experience in the application of US GAAP. This control weakness results in a
reasonable possibility that a material misstatement in the notes of the consolidated financial statements on the differences between Canadian and United States generally accepted accounting principles will not be prevented or detected on a timely
basis. Specifically, the Companys disclosure controls initially failed to identify the impact of new accounting pronouncements in the Company and other amendments to related note disclosures. These errors were corrected by management prior to
the issuance of the Companys December 31, 2007 consolidated financial statements.

The Company does not have sufficient personnel with the
necessary knowledge, experience and training in the application of income tax commensurate with the Companys financial reporting requirements. This control weakness results in a reasonable possibility that a material misstatement in the notes
of the consolidated financial statements on income taxes will not be prevented or detected on a timely basis. These errors were corrected by management prior to the issuance of the Companys 2007 consolidated financial statements.

Based on our assessment and because of the material weaknesses described above, management has concluded that our internal control over financial reporting was not
effective as of December 31, 2007.



---

The effectiveness of the registrants internal control over financial reporting as at December 31, 2007 has
been audited by BDO Dunwoody LLP as stated in their Auditors Report that accompanies the registrants consolidated financial statements for the fiscal year ended December 31, 2007 files as Exhibit 99.2 to this Annual Report on Form
40-F.

Remediation of Control Weakness

The
Company will enhance its US GAAP accounting and tax staff training and development. Additionally, the Company will increase the use of services of outside consultants who have expertise in complex US GAAP accounting and tax matters to
assist in identifying and resolving complex issues.

Changes in Internal Control over Financial Reporting

During the fiscal year ended December 31, 2007, there were changes in the registrants internal control over financial reporting that have materially affected,
or are reasonably likely to materially affect, the registrants internal control over financial reporting, as follows:

The registrant has enhanced
controls surrounding interim end and year end reporting. One of the major enhancements is improved documentation over the financial statement preparation.

AUDIT COMMITTEE

The Board of Directors has a separately-designated standing Audit Committee for the purpose of
overseeing the accounting and financial reporting processes of the Company and audits of the Companys annual financial statements. As at the date of this Annual Report, the Audit Committee was comprised of Allan Marter, Jack Crabb and Gary
Craig.

Audit Committee Financial Expert

Allan Marter
serves as a member of the audit committee of the Companys Board of Directors. The Board of Directors has reviewed the definition of audit committee financial expert under item 8(a) of General Instruction B to Form 40-F and
determined that Allan Marter satisfies the criteria for an audit committee financial expert under the Exchange Act. The SEC has indicated that the designation of Allan Marter as an audit committee financial expert does not make Allan Marter an
expert for any purpose, impose any duties, obligations or liability on Allan Marter that are greater than those imposed on members of the audit committee and board of directors who do not carry this designation or affect the duties,
obligations or liability of any other member of the audit committee. Mr. Marter is independent as defined in Section 803 of the listing standards of the American Stock Exchange.

CODE OF ETHICS

At this time, we have not adopted a
formal code of ethics that applies to our President and Chief Financial Officer. We have, however, followed an informal code of ethics requiring Board of Director approval of any transaction in which our President or our Chief Financial Officer has
a material interest. We believe this procedure reasonably deters material wrongdoing and promotes honest and ethical conduct from our executive officers.

|(1) | Under terms of the project financing facility for the San José mine, a subsidiary of Hochschild will lend 51% of a bridge loan and permanent financing directly to MSC and 49%
of the loan will be lent to Minera Andes which in turn will lend the funds to MSC. The amount shown above is the loan that Minera Andes owes Hochschild and is mirrored by a loan in equal amount that MSC owes Minera Andes. The loan will be paid out
of cash flow from the mine. See Note 4b in the December 31, 2007 consolidated financial statements for additional details.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | Macquarie Bank Limited. See Note 6 in the December 31, 2007 consolidated financial statements for additional details.
|--- | ---------------------------------------------------------------------------------------------------------------------

|(3) | Contingency consists of various lease agreements for office and storage space in Spokane, United States, Vancouver, Canada and Mendoza, Argentina.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------

The table of contingencies above does not include the following:

On
December 2, 2003, we signed an agreement that obligated us to pay N.A. Degerstrom, Inc. a royalty of $250,000 if any of the current properties, other than the properties comprising the San José project, meet certain conditions such as
bankable feasibility or commercial production. Our obligation expires December 31, 2013. As of December 31, 2007 no payments are required under this agreement.

In addition, mineral rights in Argentina are owned by the federal government and administered by the provinces. The provinces can levy a maximum 3% mouth of mine (gross proceeds) royalty. The provinces of
Mendoza and Neuquén have waived their right to a royalty. The provinces of Río Negro, San Juan, Santa Cruz and Chubut have not yet established a policy regarding the royalty.

We are obligated to fund our 49% of costs at San José that are not funded by project financing as well as 49% of capital contributions or our ownership will be
diluted. In December 2007, the shareholders of MSC agreed to increase the share capital of MSC by $34,500,000, of which $16,905,000 represented Minera Andes portion, which was accrued as a liability at December 31, 2007. The Company
paid this amount in January 2008. As of December 31, 2007, we do not expect to have further cash calls as the Company is now operating and plant expansion costs are to be paid from cash flow of the operation.

MSC has signed agreements with third party providers relating to the development of the San José/Huevos Verdes project. Our 49% portion of these commitments is
approximately $16 million.



---

On November 8, 2007, we entered into an agreement with a consultant that requires the payment of $30,000 per month
for the term of the agreement. The term is unspecified and can be cancelled at any time after February 2008.

In March 2007, we received a two-year loan
from Macquarie Bank Limited for $7.5 million of which $5.88 million was for the development of the San José project and $1.62 million was for general purposes. The main purpose of the loan was to provide additional funding to Minera Andes for
its 49% portion of the costs of the exploration, sustaining capital, cost overruns and expansion related costs of the MSC project that entered its production commissioning phase in the third quarter of 2007.

In October 2007, Minera Andes received another tranche of $10 million on the existing loan facility from Macquarie. The total loan facility to them is $17.5 million. The
main purpose for the October 2007 loan was primarily for Minera Andes 49% share of the October cash call from MSC of $17.4 million for costs of mine construction, expansion of the exploration program which includes drilling new targets,
expanding the reserves and resources, and for general working capital. In October 2007, Minera Andes sent funds of $8.53 million to MSC to fund its 49% portion of the cash call. See Note 6 in the December 31, 2007 consolidated financial
statements for additional details.
