Also, many of the factors are beyond our control.  Accordingly, readers should not place undue reliance on forward-looking statements or information.  We undertake no obligation to reissue or update forward-looking statements or information as a result of new information or events after the date of this AIF except as may be required by law.  All forward-looking statements and information made in this document are qualified by this cautionary statement.



Cautionary Note to U.S. Investors  Information Concerning Preparation of 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) under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the CIM) CIM Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council as may be amended from time to time by the CIM.



2



---



The definitions of proven and probable reserves used in NI 43-101 differ from the definitions in the United States Securities and Exchange Commission (SEC) Industry Guide 7.  Under SEC Industry 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 the 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 or inferred mineral resources may not form the basis of feasibility or prefeasibility 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 US companies subject to the reporting and disclosure requirements under US federal securities laws and the rules and regulations thereunder.

DEVELOPMENT AND DESCRIPTION OF THE BUSINESS

Overview



3



---

Minera Andes Inc. was formed upon the amalgamation of Scotia Prime Minerals, Incorporated and Minera Andes Inc. pursuant to theBusiness Corporations Act (Alberta) on November 6, 1995.  Commencing on February 7, 2007, Minera Andes was listed on the Toronto Stock Exchange (the TSX) (symbol: MA).  Prior to February 7, 2007 Minera Andes was listed on the TSX Venture Exchange (the TSXV), having initially been listed thereon on December 20, 1995.  Minera Andes common shares are also quoted on the NASD OTC Bulletin Board (symbol: MNEAS).



Our head office is 111 E. Magnesium Road, Suite A, Spokane, Washington, 99208, and our principal business address is Coronel Moldes 837/820, (5500) Mendoza, Argentina. Our registered and records office and address for service is 7415B 35th Ave. N.W., Calgary, Alberta, T3B 1T4 Canada.



Our principal business is the exploration and development of mineral properties, located primarily in the Republic of Argentina, with a focus on gold, silver and copper mineralized targets.  We carry on our business by acquiring, exploring and evaluating mineral properties through our ongoing exploration program.  Following exploration, we either seek to enter into joint ventures to further develop these properties or dispose of them if they do not meet our requirements.



We currently hold mineral rights and applications for mineral rights covering approximately 304,221 acres (123,133 hectares) in Argentina, however our principal assets currently consist of:

(i)

a 49% interest in the San José Project, an operating gold and silver mine;

(ii)

a 100% interest in certain mineral properties comprising part of the Los Azules Project, a porphyry copper exploration project; and

(iii)

an option to acquire a 100% interest in the balance of Los Azules Project upon the satisfaction of certain conditions and subject to a back-in right, as to 51% of the entire Los Azules Project held, indirectly, by Xstrata plc.

The following chart illustrates the Corporations principal subsidiaries, together with the governing law of each company and the percentage of voting securities beneficially owned or over which control or direction is exercised by the Corporation, as well as the Corporations principal mineral properties.

---



As indicated above, the Corporations interest in the San José Project is held by Minera Andes S.A. (MASA) and the Corporations interest in the Los Azules Project is held by MASA and by Andes Corporacion Minera S.A. (ACMSA).



The San José Project



The San José Project is a gold-silver project located in Santa Cruz Province, Argentina.  The San José Project is a joint venture pursuant to which title to the assets is held by Minera Santa Cruz S.A. (MSC), an Argentinean corporation.  MSC is owned, as to 49%, by MASA and, as to 51%, by Hochschild Mining (Argentina) Corporation S.A., a subsidiary of Hochschild Mining plc (together with its affiliates and subsidiaries, Hochschild).  See Option and Joint Venture Agreement.



The Corporations interest in, and the affairs of, MSC are governed by an option and joint venture agreement dated March 15, 2001 between MASA and Hochschild (as amended by agreements dated May 14, 2002, August 27, 2002 and September 10, 2004 (the OJVA).



5



---

Under the OJVA we are entitled to appoint two of the five members of the Board of Directors of MSC and Hochschild is entitled to appoint the balance of the members of the Board of Directors of MSC.  The OJVA grants us a veto in respect of certain and very limited matters regarding the affairs of MSC and the operation of the San José Project.  In particular, we have a limited, if any, ability to control the timing or amount of cash calls and decisions made in that regard may have an adverse affect on our operations and financial position.  See The OJVA.



We have the right to receive, upon request, information regarding the San José Project.  However, it has been managements experience that the information it receives from MSC is often not responsive to the particular request made, can be inconsistent and is subject to frequent change.



To address this situation, in 2007, the Corporation retained an engineering company to monitor the operation of the San José Project and report its findings to the Corporation.  This proved to be ineffective and commencing October 2008, the Corporation has retained in-house personnel, located in Argentina and North America, to facilitate the transfer of information from MSC.  This personnel regularly attends MSCs offices to verify information provided.  Management believes that this approach has improved the quality and timeliness of information available to it regarding the operation of the San José Project.



Project financing for the San José Project is currently provided pursuant to a letter agreement dated October 10, 2006 (as amended by agreements dated October 17, 2006, October 24, 2006, January 5, 2007, January 25, 2007, February 26, 2007, February 28, 2007, March 29, 2007, April 26, 2007 and June 29, 2007, the Project Loan Letter Agreement) between Minera Andes, MSC and by assignment, Hochschild Mining Holdings Limited (the Hochschild Lender), an affiliate of Hochschild Mining plc.  SeeProject Loan Letter Agreement.



Pursuant to the Project Loan Letter Agreement, the Hochschild Lender has effectively loaned to MSC the aggregate principal amount of $65 million, which amount, plus accrued interest is to be repaid by MSC using cash not required for operations and in priority to the distribution of any other amounts to the shareholders of MSC.



The San José  Project has also been, and may in the future, be financed by way of shareholder loans from the Corporation and Hochschild pursuant to a loan agreement between MSC, MASA, the Corporation, the Hochschild Lender and Hochschild dated September 10, 2004 (as amended by agreement dated December 15, 2005, the "Loan Agreement").  See "Loan Agreement".



The San José processing facility commenced production during the second quarter of 2007 and full commercial production of 750 metric tonnes per day (MTPD) was reached in the first quarter of 2008.  The first sale of metals from the San José mine occurred in December 2007.



In October 2008 capacity at the San José processing plant was increased from 750 MTPD to 1,500 MTPD and by December 2008 the plant was operating at this increased capacity of 1,500 MTPD.  Approximately 37% of the concentrate produced at the mill is currently converted on site to doré bullion.



Work is underway to also increase mine production from 750 MTPD to 1,500 MTPD, primarily by accessing the Kospi vein, located between the Huevos Verdes and Frea veins from which current production is derived. However due to difficult ground conditions access to the Kospi vein has been delayed until approximately the first quarter of 2009, with production therefrom anticipated to commence by the third quarter of 2009.  In the meantime, mill feed is being generated from expanded mine production at the Huevos Verde and Frea veins and from a surface stockpile of low grade ore.



A project is also underway to connect the San José processing facility to the national power grid through the construction of a 130 kilometer 132 kV electric transmission line.  This project was due to be completed by the end of September 2008, however the Province of Santa Cruz denied MSCs application for the permits to build the electric line along the right of way of the Provincial highway. As a result, it was necessary to redesign and lengthen the location of the electric line and negotiate agreements with private land owners along the redesigned route.  The connection is expected to be completed during the first quarter of 2009.  Meanwhile, there is sufficient diesel generating capacity at the mine to run the mill at its full expanded capacity.

---

MSC has purchased part of the equipment necessary to expand the electrowinning circuit so that 100% of the concentrates produced by the operation can be converted to doré on site, however the project has been postponed until such time as it can be financed out of cash flow from operations.



During 2007, approximately 28,585 meters of core drilling totaling 112 drill holes on several targets identified at the San José Project had been completed.  Drilling in the second half of 2007 defined 2.8 km of strike length along the Odin and Ayelén veins.



During 2008 approximately 19,358 metres of core drilling totaling 81 drill holes has been completed at the San José Project.  Drilling focused primarily on the Frea, Odin and Ayelén veins consisting of infill and step-out drilling.  Highlights of the program included:



·

Frea Vein:  Drill hole SJD-477 which intersected three high-grade splays of the main Frea vein of 0.30 meters grading 25.23g/t (0.81 opt) gold and 4,945 g/t (159 opt) silver and 0.93 m grading 14.82 g/t (0.48 opt) gold and 1,688 g/t (54 opt) silver and 1.30 meters of 13.30 g/t (0.43 opt) gold and 1.532 g/t (49 opt) silver.

·

Odin Vein:  A total of 37 holes were drilled on the Odin vein (bringing the total to 88 holes) covering approximately 1600 meters along the strike of the vein, to a depth of approximately 200 meters.  Hole SJD-483 intercepted 2.12 meters of 6.91 g/t (0.20 opt) gold and 486 g/t (14.2 opt) silver.  The Odin vein remains open to the west along strike and to depth.

·

Ayelén Vein:  Additional mineralization was identified along the 1.2 kilometers of strike and 200 meters of depth.   However the 2008 drilling encountered predominantly moderate to low grade mineralization.



Management believes that the new silver/gold mineralization discovered in the Odin, Ayelén and Frea veins represents additional mineralization that could potentially increase the Mineral Reserves and Mineral Resources at the San José Project.



As at December 31, 2008 the San José mine comprised more than 18 km of underground workings accessed by two ramps and a third ramp has been constructed to access the Kospi vein.



The exploration results above have been prepared by or under the supervision of Brian Gavin, Vice President  Exploration of the Corporation and a qualified person within the meaning of NI 43-101.  Mr. Gavin verified the data disclosed, including sampling, analytical and test data underlying the results set out above.  Splits from the drill core samples were submitted to Alex Stewart Assayers, Argentina, S.A., in Mendoza, Argentina, for fire assay and ICP analysis. The accuracy of results was tested through the systematic inclusion of standards, blanks and check assays.



The Los Azules Project

The Los Azules Project is an exploration project comprised of properties owned by MASA (the MASA Properties) and adjoining properties owned by MIM Argentina Exploraciones S.A. for Xstrata Copper, one of the commodity business units within Xstrata plc (MIM and the MIM Properties).  Under the terms of an option agreement among MASA, Minera Andes Inc., Xstrata Copper (through MIM) and Xstrata Queensland Limited (Xstrata plc, together with its affiliates, is hereinafter referred to as Xstrata) dated November 2, 2007 (the Los Azules Option Agreement): (i) MIM granted MASA an option to acquire a 100% interest in the MIM Properties, exercisable on or before November 24, 2010 upon satisfaction of certain conditions including delivery of a scoping study/preliminary assessment whereupon the MIM Properties and the MASA Properties would be consolidated and held by MASA (the Combined Property); and (ii) MASA granted MIM (upon the exercise of the preceding option by MASA) an option to acquire a 51% interest in the Combined Property upon, among other things, payment to the Corporation of an amount equal to three times the amount of the direct expenditures paid by MASA and its affiliates since November 25, 2005 on exploration of the Combined Property.  See Los Azules Option Agreement.



An amendment or other acknowledgement is being prepared to formally include certain properties registered to ACMSA as MASA Properties and hence, subject to the Los Azules Option Agreement.



7



---

Certain of the MIM Properties are subject to an underlying option agreement, which is the subject of a dispute between Xstrata, as option holder, and Solitario Argentina S.A. (Solitario), as the grantor of that option and the holder of a back-in right of up to 25%, exercisable upon the satisfaction of certain conditions, within 36 months after the exercise of the option by Xstrata.  The dispute surrounds the validity of the 36 month restriction described above.  If Solitario is successful, MIMs interest in substantially all of the MIM Properties may be reduced by up to 25% and upon exercise of the MASA Option, MASAs interest in that part of the Combined Property may be similarly reduced (the Solitario Claim).  See Los Azules Option Agreement.



A preliminary assessment in respect of the Los Azules Project has been completed and is expected to be delivered to Xstrata in the near future.  In the meantime, the Corporation is assessing the Los Azules Project in light of current economic conditions and no decision has been made to exercise its option to acquire a 100% interest in the MIM Properties and/or proceed with development of the Project.



Bank Loan

Pursuant to a credit agreement (the Macquarie Credit Agreement) with Macquarie Bank Limited (Macquarie), Macquarie has made two non-revolving term loans to us, in the aggregate principal amount US$17.5 million.  See Macquarie Bank Loan.

History

The San JoséProject

In October 2005 MSC completed a bankable feasibility study at the San José Project which led to the development of the San José Project.



In March 2006, the Environmental Impact Assessment, the primary document for permitting the San José Project, was approved by the province of Santa Cruz, Argentina and a final decision was made to place the San José Project into production.



In October 2006, the Corporation, MSC and the Hochschild Lender finalized the terms and conditions of the Project Loan Letter Agreement.  Pursuant to the Project Loan Letter Agreement, the Hochschild Lender agreed to provide a project financing loan (the Project Loan) to MSC for up to US$65 million.



In March 2007, an aggressive exploration program was approved for the San José Project by MSC, with an objective of adding new reserves and resources, and identifying new veins to increase mine life.



The San José processing facility commenced production during the second quarter of 2007.



In August 2007, a decision was made by MSC to double production capacity from 750 MTPD to 1,500 MTPD.  Also, in August 2007,MSC entered intoa one year refining and sale contract (as subsequently extended by agreement dated January 29, 2008 for 18 months commencing August 2007) with Argor Heraeus S.A. (Argor) a refinery based in Switzerland, providing a market for gold and silver produced as doré bullion from the San José Project.



In the third quarter of 2007, MSC commenced a program to expand mine production from 750 MTPD to 1,500 MTPD, primarily by accessing the Kospi vein.



During 2007, approximately 28,585 meters of core drilling totaling 112 drill holes on several targets identified at the San José Project had been completed.  Drilling in the second half of 2007 defined 2.8 km of strike length along the Odin and Ayelén veins.



8



---

In February 2008,MSC entered into a sale purchase contract in respect of 3,800 dry metric tonnes of concentrate with Norddeutsche Affinerie (NA) a smelting and refining company based in Germany.



The San José processing facility commenced full commercial production of 750 MTPD in the first quarter of 2008 however, the first sale of metals from the San José Project occurred in December 2007.



In May 2008 work commenced to connect the San José mine to the national power grid through the construction of a 130 kilometre 132 kV electric transmission line.



In October 2008, the expansion of the processing plant to a capacity of 1,500 MTPD was completed and by December 2008, the plant had commenced operating at the increased capacity of 1,500 MTPD.



During 2008, approximately 19,358 metres of core drilling totaling 81 drill holes were completed at theSan José Project.



The Los Azules Project



In November 2005, the Corporation signed a term sheet with Xstrata Copper, one of the commodity business units within Xstrata in respect of the matters provided for in the Los Azules Option Agreement.



In May 2006, the Corporation reported the discovery of significant high-grade copper at its Los Azules Project with an eleven hole drill program returning intervals up to 1.6% copper over 221 meters and 1% copper over 173 meters in separate holes.



In November 2007, the Los Azules Option Agreement was executed.  The Los Azules Option Agreement provides for the consolidation of adjoining properties owned by MIM and MASA and which straddle a large copper porphyry system.



Between 2006 and 2008 the Corporation drilled 64 core holes totaling 11,572 meters at the Los Azules project and commenced preparation of the preliminary assessment contemplated by the Los Azules Option Agreement.



In September 2008, and in connection with the preliminary assessment, the Corporation completed a metallurgical testing program indicating that the mineralized material at the Los Azules Project is amenable to conventional flotation recovery methods and that the overall metal recoveries and the copper concentrate grades are high.



In September 2008, an independent resource estimate was completed in respect of the Los Azules Project and the Los Azules Technical Report was filed.



In February 2009, the preliminary assessment was completed and the results thereof announced by news release dated February 5, 2009.



Corporate



In December 2005, Mr. Robert McEwen, Chairman and CEO of U.S. Gold Corp, and founder and former Chairman and CEO of Goldcorp Inc., agreed to invest a total of C$10 million in Minera Andes by private placement.



In March 2006 Mr. McEwen purchased 1.2 million shares of Minera Andes in the market at a price of C$1.10 per share.  In addition, in May 2006, Mr. McEwen exercised all the common share purchase warrants then held by him.  As a result, a total of 14,285,714 common shares were issued resulting in gross proceeds of C$7,857,143 to Minera Andes.  Mr. McEwen then held 30% of the then issued and outstanding common shares of the Corporation.



In February 2007, the Corporations shares were listed on, and commenced trading on, the TSX.  The Corporations shares were previously listed and traded on the TSXV.



In March 2007, the Corporation received a two-year loan from Macquarie for $7.5 million, of which $5,880,000 was for the development of the San José Project and $1,620,000 was for general corporate purposes.

In October 2007, Minera Andes received an additional two-year loan from Macquarie in the principal amount of US$10 million (which amount together with the $7.5 million referred to in the preceding paragraph is hereinafter referred to as the Bank Loan).  The main purpose of this additional loan was to provide additional funding to Minera Andes for its 49% share of exploration and sustaining capital costs, cost overruns and expansion related costs at the San José Project.



Between December 2007 and February 2008, the Corporation completed private placements consisting of the issue of a total of 22,085,668 units, at a price of C$1.55 per unit, for gross proceeds of C$34.23 million. The proceeds from the offering were primarily used to fund the Corporations share of the costs at the San José Project and for exploration drilling and completing a preliminary assessment at the Los Azules Project.

Option and Joint Venture Agreement



Under the OJVA, MASA transferred all of its rights in the San José Project to MSC, a newly formed corporation organized under the laws of Argentina and wholly owned by the Corporation.  In July 2003, Hochschild earned a 51% ownership interest in MSC by expending a total of US$3 million, including a minimum of US$100,000 per year on exploration targets.  Upon Hochschild acquiring a 51% ownership in MSC, Minera Andes elected to participate in the development of the San José Project on a pro-rata basis.



The OJVA and the by-laws of MSC provide, in relevant part, that:



(i)

the Board of Directors of MSC shall, at all times, consist of five directors and that, in effect, three of such directors shall be nominated by Hochschild and two directors shall be nominated by MASA;

(ii)

the Board of Directors of MSC shall meet at least once every calendar quarter, without any stipulation that a nominee of each of Hochschild and MASA be present;

(iii)

at any meeting of the Board of Directors of MSC, each of MASA and Hochschild shall have that number of votes equal to the number of directors it is entitled to appoint;

(iv)

MSC shall finance its operations and activities from such sources as the Board of Directors of MSC sees fit;

(v)

the only actions by MSC requiring unanimous approval of both MASA and Hochschild are (a) a sale of all or substantially all of the assets of MSC; (ii) any amendment to the articles of MSC that would have an adverse effect on the rights of any particular shareholder to receive its share of the profits of MSC; (c) entering into any new line of business; (d) acquiring real property or conducting exploration, development or mining outside of the property initially transferred to MSC for the purposes of establishing the joint venture; or (e) any merger or other corporate combination involving MSC; and

(vi)

in the event of a disagreement between Hochschild as majority owner and MASA as minority owner, concerning any act of MSC that requires the unanimous approval of the Board of Directors of MSC, Hochschild has the option to purchase all of the shares of MSC held by MASA for fair value.

The OJVA provides that MSC shall finance its operations from such sources as the Board of MSC shall determine, including by issuing additional shares. In such event, each shareholder of MSC has a pre-emptive right to subscribe for its pro rata share of the additional shares.  Any shares not subscribed by a shareholder shall be offered to the other, participating, shareholder.  As a result, full exercise of a shareholders pre-emptive right (assuming full exercise by other shareholder) maintains its shareholdings in MSC at current levels while a failure to exercise its pre-emptive rights, in full, may result in dilution (the extent of such dilution depending on whether the other shareholder exercises its pre-emptive right and to what extent and whether such shareholder also purchases shares not purchased by the first shareholder).  A portion of the operating and capital costs of the San José Project have been financed by issuing additional shares of MSC.



The OJVA also provides that it shall be the policy of MSC to maintain excess distributable cash and that unless the Board of MSC unanimously decides otherwise, MSC shall distribute, on a semi-annual basis all cash not reasonably required for operations or expansion.



Project Loan Letter Agreement



Under the Project Loan Letter Agreement, the Hochschild Lender and Minera Andes Inc. agreed to provide MSC with an unsecured bridge loan in the aggregate amount of $20 million (the Bridge Loan).  The Project Loan Letter Agreement provides that the Bridge Loan was to be structured as loans to MSC by each of Minera Andes and the Hochschild Lender, in each case, in amounts proportionate to the shareholdings of Minera Andes and Hochschild in MSC.



11



---

The Project Loan Letter Agreement however, further provides that the loan to be made by Minera Andes to MSC would be structured as (i) a loan by the Hochschild Lender to Minera Andes (the Project Loan Payable); and (ii) a corresponding loan by Minera Andes to MSC (the Project Loan Receivable).  As a result, the Bridge Loan was made by way of (i) a loan by the Hochschild Lender to MSC in an amount equal to 51% of the amount of the Bridge Loan; (ii) a loan by the Hochschild Lender to Minera Andes in an amount equal to 49% of the amount of the Bridge Loan; and (iii) a corresponding loan by Minera Andes to MSC in the same amount and on the same terms as the preceding loan by the Hochschild Lender to Minera Andes.  Both the Project Loan Payable and the Project Loan Receivable bear interest at the same rate and upon the same terms (including repayment).



The Project Loan Letter Agreement also provides for a permanent secured project loan in the aggregate amount of $65 million (the Project Loan), structured in the same manner as the Bridge Loan, and replacing the Bridge Loan, to be documented in definitive agreements, which, as of the date of this Revised AIF, have not been settled or entered into.



Amounts advanced under the Project Loan Letter Agreement by the Hochschild Lender to Minera Andes and then by Minera Andes to MSC are currently unsecured except that, as security for the loan made by the Hochschild Lender to Minera Andes, Minera Andes has pledged to the Hochschild Lender, its right to the repayment of the corresponding loans made by Minera Andes to MSC.



The current drafts of the definitive agreements (the Draft Loan Documents) and the Project Loan Letter Agreement provide that the Project Loan will be secured by a security interest granted by MSC in favour of the Hochschild Lender and Minera Andes in certain MSC bank accounts.  In addition, under the Draft Loan Documents, Minera Andes will be required to (i) continue to pledge, to the Hochschild Lender, Minera Andess right to receive repayment of the loans made by Minera Andes to MSC; and (ii) grant to the Hochschild Lender a security interest in Minera Andess security interest in MSCs bank accounts.  Minera Andes will also be required to direct MSC to pay all amounts owing by it to Minera Andes directly to the Hochschild Lender with such amounts being concurrently applied against amounts owing by MSC to Minera Andes and the corresponding amounts owing by Minera Andes to the Hochschild Lender.



The Hochschild Lender and MSC have agreedthat until the Draft Loan Documents are finalized, no payment of interest or principal will be due.  The Project Loan Letter Agreement and the Draft Loan Agreements provide that the Project Loan shall be repaid by MSC using cash not reasonably required for operations, maintenance, taxes, debt service, working capital, exploration programs, reinvestment or expansion of any existing mine or the development of any new mine but in priority to the payment of any other amounts to the shareholders of MSC or the making of any other distribution to the shareholders of MSC.



The Project Loan currently bears interest at LIBOR plus 2.50%.  It has been agreed that once the Draft Loan Documents are finalized, interest will increase to LIBOR plus 2.85%.



Loan Agreement

By the terms of Loan Agreement, shareholder loans made thereunder are unsecured, repayable by MSC on the "maturity date", bear interest at the rate of 9% per annum and are subordinated to all other borrowing by the MSC.  For the purposes of the Loan Agreement "maturity date" means the date that is two years after the date upon which mining operations have first been conducted by MSC for a period of at least 90 consecutive days at a rate of at least 75% of planned operating capacity".



The Loan Agreement also contains covenants by MSC that (i) it will do all things necessary to comply with all laws applicable to it; (ii) it will obtain and take all action to ensure the continuance of all consents, licenses, filings and registrations and governmental approvals required with respect to the Loan Agreement; and (iii) it will procure that its obligations under this Agreement are preferred with respect to all of the MSC's other present and future unsecured and unsubordinated obligations, other than those preferred by law.



12



---

Under the Loan Agreement, it is an event of default if (i) MSC fails to pay, any amount due thereunder, as and when required; (ii) any representation made by MSC therein proves to be incorrect in any material respect; (iii) MSC fails to perform or observe any covenant thereunder and such failure continues for 15 consecutive days after notice thereof; (iv) MSC becomes insolvent or bankrupt or a trustee is appointed in respect of all or a substantial part of its assets or similar proceedings are instituted; (v) an execution is levied against all or a substantial part of the assets of MSC and not discharged within 30 days; or (vi) in the reasonable opinion of the lenders, there is imminent danger that MSC will lose all or any substantial part of its properties or assets.



It is a term of the Loan Agreement that proceeds of loans made thereunder be used to fund MSC's costs and investments including, intangible assets, properties and equipment, mining exploration, evaluation and development activities.



Los Azules Option Agreement



On November 2, 2007, the Corporation, MASA, Xstrata and MIM entered into the Los Azules Option Agreement in respect of the MASA Properties and the adjoining MIM Properties.  Under the Los Azules Option Agreement, MASA has an option, exercisable until November 24, 2010 to acquire a 100% interest in the MIM Properties (the MASA Option).  If MASA exercises the MASA Option, MIM has the option to back-in to the Combined Property for a 51% interest.



In order to exercise the MASA Option, MASA must incur US$1 million in expenditures on the MIM Properties, deliver to MIM an independent scoping study and technical report in respect of the Combined Property (the Los Azules Preliminary Assessment) and deliver a notice of exercise.  MASA has incurred and paid in excess of US$1 million in expenditures and expects to deliverthe Los Azules Preliminary Assessment to MIM shortly.  MASA however has not, as of yet, elected to exercise the MASA Option.



On exercise of the MASA Option, MIM is required to transfer the MIM Properties to MASA.  However, if in the opinion of MIM, the Los Azules Preliminary Assessment shows the potential to economically produce 100,000 tonnes (200 million pounds) of contained copper per year for 10 years or more then MIM has the right to earn a 51% interest in the Combined Property (the Back-in Right). To satisfy the conditions of the Back-in Right, MIM must assume control and responsibility for the Combined Property, make a cash payment to Minera Andes of three times MASAs and its affiliates direct expenditures incurred and paid on the Combined Property after the 25th of November 2005 and complete a bankable feasibility study within five years of its election to exercise the Back-in Right. In the event that the Los Azules Preliminary Assessment does not, in MIMs opinion, meet the criterion contemplated above, MIMs interest is reduced to a right of first refusal on a sale of the Combined Property, or any part thereof.  All lands that comprise the Combined Propertys mineral applications are subject to a provincial mouth of mine royalty of between zero and 3%. This royalty will be negotiated with the province of San Juan as the project advances.



Upon exercise of the Back-in Right, the Combined Property will be transferred to a new operating company (Newco) and Xstrata and MIM will use commercially reasonable efforts to obtain project financing for the development of a mine as contemplated by the bankable feasibility study.  If the project financing arrangements are accepted by MASA and such financing completes, MIM will earn an additional 4% interest in the project, thereby reducing MASAs interest from 49% to 45%.  If the project financing arrangements are rejected by MASA or if they are accepted by MASA but the project financing does not complete within a prescribed time (other than as a result of the acts or omissions of Xstrata and/or MIM), MASA will be solely responsible for the costs and expenses incurred by Xstrata and MIM in attempting to obtain such project financing.



The failure by MASA or MIM to pay the costs and expenses for which they are responsible from the date that MIM satisfies the conditions of the Back-in Right will result in a dilution of their respective interest in the operating company.



13



---

MASA and MIM are to use good faith efforts to negotiate and execute a shareholders agreement governing Newco, pending which Newcos activities will be limited to those activities necessary to deliver the bankable feasibility study and maintain the Combined Property in good standing.  From the date that MIM satisfies the conditions of the Back-in Right up until the date on which a shareholders agreement is signed, each of MASA and MIM will have a right of first refusal over any bona fide offer received by the other from a third party purchaser (other than an affiliate) to purchase any of its interest, directly or indirectly, in the project.



If before MASA and MIM have negotiated and executed a mutually agreeable shareholders agreement for Newco: (a) MASA sells, assigns, transfers, conveys or otherwise disposes of all or any of its rights or interests in whole or in part in Newco or the Combined Property to any person other than an affiliate (an assignment); or (b) there is a change of control of MASA, the following shall occur: (i) where the assignment occurs prior to the date on which MIM satisfies the conditions of the Back-in Right, the provisions restricting the activities that may be undertaken by Newco after MIM satisfies the conditions of the Back-in Right will be invalidated and, where the assignment occurs after that date but before the execution of a shareholders agreement, those same restrictions as to the activities that may be undertaken by Newco will be of no further force and effect; (ii) the obligation of MIM and Xstrata to use commercially reasonable efforts to obtain project financing will be invalidated; and (iii) where the assignment occurs after the date on which MIM satisfies the conditions of the Back-in Right, Newco will be entitled to commence the development of a mine within 6 months from the effective date of such assignment.



The obligations of MASA under the Los Azules Option Agreement are guaranteed by the Corporation and the obligations of MIM are guaranteed by Xstrata.  The Los Azules Option Agreement imposes certain restrictions on the ability of the Corporation to enter into a transaction whereby a person acquires more than 50% of the Corporations ownership interest in MSC as at November 2, 2007.   The Los Azules Option Agreement also restricts the ability of the Corporation to enter a transaction whereby the Corporation ceases to hold the shares of Newco issued to MASA, the MASAs Propertiesor the Combined Property, as the case may be.



The Corporation is required to consult with Xstrata and MIM immediately after a sale by MSC of its interests in the San José Project and prior to any distribution of proceeds from such sale by the Corporation to its shareholders.



The MIM Properties are subject to an underlying option agreement under which MIM was granted the option to acquire a 100% interest in approximately 1,400 hectares.  MIM has advised that this option was exercised on August 14, 2007 and the only remaining payment thereunder is a payment of US$500,000 payable within 30 days after the completion of a feasibility study.



The remainder of the MIM Properties are subject to an option agreement between MIM and Solitario under whichMIM was granted an option to acquire a 100% interest in those MIM Properties, subject to the right of Solitario to back-in for up to a 25% interest in those properties if MIM completes a feasibility study on the subject property within 36 months of MIM exercising the option.  To exercise the back-in right, Solitario must pay to MIM two times the corresponding percentage proportion of MIMs actual expenditures in relation to the properties (for example, if Solitario backs-in in for 25%, the payment obligation is two times 25% of MIMs actual expenditures).  If Solitario elects to back-in for 5% or less, or if Solitario backs-in for more than 5% but its interest is subsequently diluted to 5% or less, its interest will convert to a one percent net smelter royalty.  The option was exercised by MIM on April 23, 2007.



Solitario together with its parent, TNR Gold Corp., has commenced an action in the Supreme Court of British Columbia against MIM seeking amongst other things, rectification of its agreement with MIM to eliminate the 36 month restriction referred to above, or alternatively, a declaration that the 36 month restriction is not enforceable.  MIM is defending the claim, however, the outcome of this Court action is not certain.  If Solitario is successful, and a feasibility study is completed at any time, MIMs interest in substantially all of the MIM Properties (and, upon exercise of the MASA Option, MASAs resulting interest therein) may be diluted by up to 25%.



14



---

In the same Court action, Solitario is seeking a declaration that the property referred to as Escorpio IV was not included in the option granted to MIM and that as a result, MIM has no interest in that property.  MIM has filed a Counterclaim against Solitario and TNR Gold Corp. seeking amongst other things, a declaration from the Court that Escorpio IV forms part of the property that was optioned to MIM and an order for Solitario and/or TNR Gold Corp. to convey a 100% interest in Escorpio IV to Xstrata.  The outcome of this action is not certain.  If MIM is successful in its claims, Escorpio IV will be included in the MIM Properties.  If MIM is not successful, Escorpio IV will be excluded.



Macquarie Bank Loan

The Corporation entered into a second amended and restated credit agreement dated as of October 22, 2007 with Macquarie (as amended by agreement dated January 7, 2009,the Macquarie Credit Agreement) under which Macquarie provided the Corporation with a non-revolving term loan in the principal amount of US$7.5 million, with a maturity date of March 7, 2009 (the First 2007 Facility) and a non-revolving term loan in the principal amount of US$10.0 million, with a maturity date of September 30, 2009 (the Second 2007 Facility and together with the First 2007 Facility, the Bank Loan).

A total of 4,066,390 share purchase warrants (the First Warrants) were issued to Macquarie as partial consideration for the First 2007 Facility and a further 4,227,669 warrants (the Second Warrants) were issued to Macquarie as partial consideration for the Second 2007 Facility.  Each First Warrant entitles the holder thereof to purchase one common share of the Corporation at a price of C$2.06 per share any time prior to March 7, 2009.  Each Second warrant entitles the holder thereof to purchase one common share of the Corporation at a price of C$2.41 per share any time prior to September 30, 2009.

The indebtedness under the Bank Loan and any hedging obligations to Macquarie are secured by:

·

a pledge by the Corporation of all of its shares in MASA;

·

a pledge by Jorge Alfredo Vargas (the Corporation’s counsel in Argentina) of, and grant of a security interest in, all of his shares in MASA (which he holds in trust for the Corporation);

·

a security interest over all present and after-acquired personal property of the Corporation, together with a floating charge over all real property interests of the Corporation;

·

a guarantee of such indebtedness by MASA in favour of  Macquarie;

·

a pledge by MASA of, and grant of a security interest in, all of its shares in MSC;

·

a subordination (inter-creditor) agreement made by the Corporation and MASA in favour of Macquarie whereby any inter-corporate liabilities are made subordinate to, and junior in right of payment to, the indebtedness owed to Macquarie.

Interest on each advance under the Bank Loan is paid during each selected interest periodat a rate equal to the LIBOR rate with respect to such interest period plus 2.0% for the First 2007 Facility, and 2.75% for the Second 2007 Facility.  Interest rates are increased by two (2%) per cent per annum in excess of the rate otherwise payable on any amount not paid when due.

The Bank Loan may be prepaid in whole or in part without penalty or bonus, subject to prior notice and payment of customary breakage costs.  The Bank Loan requires mandatory prepayment when there is a disposition of all or a portion of the Corporations interest in the Los Azules Project to a third party, with prepayment being in the amount of the net cash proceeds so received.

The Macquarie Credit Agreement contains covenants similar to those found in arms length secured financings of this nature including:

·

the Corporation must maintain a minimum balance of unencumbered cash and cash equivalents equal to the aggregate of 100% of cash calls made by MSC but unpaid in the then current month, 49% of the budgeted expenditures on account of the San José Project in the immediately following three calendar months to the extent such expenditures are not funded by the Project Loans made under the Project Loan Letter Agreement, and 100% of the budgeted corporate expenditures and interest expenses to be paid by MAI in the immediately following quarter;

·

the Corporation must hold at least 99.995% of the issued and outstanding shares of MASA;



15



---

Competitive Conditions

The base metal mineral exploration and mining business is a competitive business.  The Corporation competes with numerous other companies and individuals in the search for and the acquisition of attractive base metal mineral properties.  The ability of the Corporation to acquire base metal mineral properties in the future will depend not only on its ability to develop its present properties, but also on its ability to select and acquire suitable producing properties or prospects for metal development or mineral exploration.

Environmental Protection Requirements

The Corporations mining, exploration and development activities are subject to various levels of federal, provincial and state laws and regulations relating to the protection of the environment, including requirements for closure and reclamation of mining properties.  See Risk Factors  Regulatory and permitting requirements significantly affect our mining operations and may have a material adverse effect on our business, financial conditions, results of operations and cash flows.



Employees

As at December 31, 2007, the Corporation had six employees and seven contractors.



Foreign Operations Risks

The San José Project and the Los Azules Project, are both located in Argentina.  Any changes in regulations or shifts in political attitudes in such foreign country are beyond the control of the Corporation and may adversely affect its business.  Future development and operations may be affected in varying degrees by such factors as government regulations (or changes thereto) with respect to the restrictions on production, export controls, income taxes, expropriation of property, repatriation of profits, environmental legislation, land use, water use, land claims of local people and mine safety.  The effect of these factors cannot be accurately predicted.  See Risk Factors  Economic and Political Instability in Argentina.



ARGENTINA

Recent Mining and Economic History in Argentina

Argentina is the second largest country in South America, over 2.7 million square kilometres in area.  In 1983, Argentina returned to a multiparty democracy, which brought an end to nearly a half century of military intervention and political instability.  The country then began to stabilize; however, it was not until 1989, with the election of the government under President Carlos Menem, that Argentina's economy began to improve.  President Menem initiated economic reforms that included the privatization of many state companies and the implementation of the Convertibility Plan, which fixed the Argentine peso to the U.S. dollar at par.  Results of the reforms were positive; Argentina's gross domestic product grew at up to 8% per annum in the early 1990s and inflation dropped to between 1% and 3% per annum.  However, following a recession in 1999 and 2000, a severe political and economic crisis occurred in late 2001.



Between 2003 and 2007, Argentina sustained a significant economic growth cycle, with an average annual growth rate of approximately 8%.  However, during the last quarter of 2007, economic growth in Argentina decreased, as a result of the current global financial crisis and in particular, significant reduction in commodity prices.



In 1993, the Mining Investments Act instituted a new system for mining investment to encourage mineral exploration and foreign investment in Argentina.  Key incentives provided by the Act include guaranteed tax stability for a 30-year period, 100% income tax deductions on exploration costs (in addition to the deductions available under the Income Tax Act), accelerated amortization of investments in infrastructure, machinery and equipment, an exemption from the tax on Minimum Presumed Income and an exemption from import duties for capital goods, equipment and raw materials used in mining and exploration.  Repatriation of capital or transfer of profits is unrestricted.  Argentina's mineral resources, administered by its 23 provinces or, in certain areas, the Argentinean federal government, are subject to a provincial royalty capped at 3% of the mouth of mine value of production, which provinces are entitled to waive or reduce.



In January 2008, the Argentinean Government reassessed regulations levying export duties on mining companies operating in the country, negatively affecting many operators.  This change in governmental policy and practice in respect of export duties did not impact the San José Project as MSC is party to a fiscal stability agreement that specifically fixes the export duty for doré bars at 5% and at 10% for concentrates.

Property and Title in Argentina

The laws, procedures and terminology regarding mineral title in Argentina differ considerably from those in the United States and in Canada. According to Argentine Political State Organisation, the mines (and their mineral thereof) belong to the provinces in which they are located, which grant the exploration permits and mine concessions to the applicants.



However, the rights, obligations, and procedures for the acquisition, exploration, exploitation, and use of mineral substances in Argentina are regulated by the federal government, pursuant to the National Mining Code (the Mining Code) while the Provinces have the power to regulate procedural aspects of the Mining Code through Provincial Mining Procedure Codes and to organise the concession and enforcement authorities.



In general, a similar concept applies to the environmental aspects related to mining activities. Although the Mining Code regulates the main aspects of environmental regulations, the provinces act as enforcement authorities. Furthermore, in application of Section 41 of the Argentine Constitution, many provinces have also enacted additional environmental laws, which are directly or indirectly, applicable to mining activities.



The following summarizes the material aspects of Argentinean mining law.



Mining Code

The Mining Code establishes three classes of minerals, two of which are: (i) the main metalliferous substances such as gold, silver, copper, lead, etc. whose ownership is vested in the provincial government, which in turn grants exploitation concessions to private companies; and (ii) the other metalliferous substances, earthy minerals, industrial minerals, etc. that belong to the land owner. Except for minerals described in preceding item (ii), mineral rights in Argentina are separate from surface ownership rights. Creek bed and placer deposits, as well as abandoned tailings and mine waste rock deposits, are included in the latter mineral class.



Cateo

A cateo is an exploration concession which does not permit mining but gives the owner a preferential right to a mining concession for the exploitation of minerals discovered in the same area. Cateos are measured in 500 ha unit areas. A cateo cannot exceed 20 units (10,000 ha).  No person may hold more than 20 permits or 400 units in a single province. The term of a cateo is based on its area: 150 days for the first unit (500 ha) and an additional 50 days for each unit thereafter. After a period of 300 days, 50% of the area over four units (2,000 ha) must be relinquished. At 700 days, 50% of the area remaining must be relinquished. Extensions may be granted to allow for bad weather, difficult access, or similar issues. Cateos are identified by a file number or dossier number.



Cateos are awarded by the following process:



(i)

an application is made in respect of a designated area, describing a minimum work program and providing an estimate of the investment to be made and a schedule for exploration;



(ii)

approval is granted by the province and a formal placement on the official map or graphic register is made provided, the requested area is not superseded by a previous mining right;



(iii)

publication of the claim is made in the provincial official bulletin so as to notify third parties of the claim, and;



(iv)

upon expiry of a period following publication in the official bulletin, the cateo is awarded.



The length of this process varies depending on the province, and often takes up to two years. Applications are processed on a first-come, first-serve, basis. During the application period, the first applicant has rights to any mineral discoveries made by third parties in the area of the cateo without its prior consent.



18



---

Until August 1995, a canon fee, or tax, of ARS$400 per unit was payable upon the awarding of a cateo. A recent amendment to the law requires that this canon fee be paid upon application for the cateo. The canon fee for the cateo is paid once for the entire term of the exploration permit.



Mina

Although the prior grant of a cateo is not a pre-condition for the granting of a exploitation right, the most common way to acquire a mina is to discover a mine as a consequence of an exploration process under a cateo. To convert an exploration concession to a mining concession, some or all of the area of a cateo must be converted to a mina. Minas are mining concessions which permit mining on a commercial basis. The area of a mina is measured in pertenencias. Each mina may consist of one or more pertenencias. Common pertenencias are six ha and disseminated pertenencias are 100 ha (relating to disseminated deposits of metals rather than discrete veins). The mining authority may determine the number of pertenencias required to cover the geologic extent of the mineral deposit in question. Once granted, minas have an indefinite term assuming exploration development or mining is in progress in accordance with applicable law.



To convert an exploration concession to a mining concession a declaration of manifestation of discovery wherein a point within a cateo must be nominated as a discovery point. The manifestation of discovery is used as a basis for location of the pertenencias. Manifestations of discovery do not have a definite area until pertenencias are proposed.  Within a period following designation of a manifestation of discovery, the claimant may do further exploration, if necessary, to determine the size and shape of the ore body.



Following a publication and opposition period and approval by the province, a formal survey of the pertenencias (together forming the mina) is completed. A surveyed mina provides the highest degree of mineral rights in Argentina.



The application to the mining authority must include official cartographic coordinates of the mine location and of the reconnaissance area, and a sample of the mineral discovered. The reconnaissance area, which may be as much as twice the surface area projection of the mine, is intended to allow for the geological extent of the ore body and for site layout and development. Excess area is released once the survey plans are approved by the mining authority.



Once the application for a mine has been submitted, the holder of the mining concession may commence the mining operation. Any person opposed to the mine operation, whether a holder of an overlapping cateo, a land owner disputing the existence of the ore deposit or the class of the economic mineral, or a partner in the discovery who claims to have been neglected, must publicly register his opposition to the operation in the official publication of the mining authority. Within 100 days of officially registering his opposition, the person opposed to the mining operation must present a legal basis to support his claim against the location, nature, or assignment of the mining concession.



Within 30 days after the resolution of any dispute against the location, nature, or assignment of the mining concession, the holder of the mining concession must submit a legal survey of the properties (lots) requested for the mine, within the maximum property limits allowed by the Mining Code. The request is published in the official bulletin and may also be subject to dispute. Approval and registration of the legal survey request by the mining authority constitutes formal title of the mining property.



New mining concessions may also be awarded for mines that were abandoned or for which their original mining concessions were declared to have expired. In such cases, the first person claiming an interest in the property will have priority. A new mining concession will be awarded for the mine in the condition left by the previous holder.



The titleholder of a mine must fulfill three conditions as part of its mining concession in order to maintain its title in good standing: (i) payment of mining canons; (ii) provision of minimum investment; and (iii) reactivation of the mine if it is shut down for more than four years, if so demanded by the mining authority.



19



---

Mining canons are paid to the state (national or provincial) under which the mining concession is registered, and are paid in equal instalments twice yearly. The canon is set by national law according to the category of the mine. In general, the canon due per year is ARS$80 per 6 ha pertenencia for common ore bodies held by the mining concession, or ARS$800 per 100 ha pertenencia for disseminated ore bodies. Failure to comply with this obligation for fourteen months results in the cancellation of the mining right. However, the titleholder can recover the mining right for a period of 45 days after being so notified by the Mining Authority, by paying the outstanding canon plus a fine equal to 20% of the unpaid canon. The discoverer of the mine is exempt from paying canons for three years from the date on which formal title was awarded to the mine.



The holder of the mining concession must also commit to investing in the fixed assets of the property to a minimum of at least 500 times the value of the annual mining canon, over a period of five years. In the first two years, 20% of the total required investment must be made each year. For the final three years, the remaining 60% of the total required investment may be distributed in another manner. The mining concession expires if the minimum required investment schedule is not met. If the exploration or exploitation works at the mine are suspended for more than four years in a row, the mining authority can require the holder of the concession to prepare and undertake a plan to activate or reactivate work. Failure to file such reactivation plan within 6 months results in the cancellation of the mining right. Such work must be completed on the property within a maximum period of five years.



A new mining operation is entitled to national, provincial, and municipal tax exemptions for five years. The exemptions commence with the awarding of formal title to the mine. As discussed above, the Mining Investment Act has established a 30-year guarantee of fiscal stability for new mining projects and/or extension of existing projects which applies retroactively, once approved, to the date of presentation of the feasibility study for the project. The law allows for accelerated depreciation of capital goods, deductions in exploration costs, and access to machinery and equipment at international prices. Depreciation of infrastructure occurs over a three year time period (60% depreciation in the first year, 20% in the second and 20% in the third) while all other depreciation occurs in a straight line method of 33.33%.



The major taxes that affect the mining sector are National Income Tax (35%), Gross Revenue Tax (1% of revenue (depending on province) and Mining Royalties (up to a maximum of 3% of the mouth of mine value of production, depending on the province).



Royalties

MSC has been granted two tax stability certificates in relation to provincial and federal taxes in Argentina dated November 21, 2005 in respect of the San José Project.  The stability certificates have a term of 30 years commencing on June 20, 2006 in respect of provincial taxes and May 15, 2006 in respect of federal taxes.

Under this agreement:

(i)

the mining royalty is fixed at 1.85% of the pit-head value per year for doré and 2.55% for mineral concentrates or precipitates; and

(ii)

the National Export Tax is fixed at 5% for doré and 10% for concentrates or precipitates although rebates are available if the final products are shipped from a maritime port (2% and 1% rebate for years 2008 and 2009, respectively).

The Province of Santa Cruz however is entitled to impose different royalty tax rates after evaluating the economic and social benefits each particular mine operation brings to the Province, provided, the royalty does not exceed the 3% determined by the Mining Investment Act.  In that respect the, Province of Santa Cruz has issued a Provincial Decree setting a range of royalties, including a royalty of between 1% and 2% for doré bares and between 2% and 3% for concentrates.

Environmental Regulation

The Environmental Protection Section of the Mining Code of Argentina, enacted in 1995, requires that each Provincial government monitor and enforce the laws pertaining to subscribed development and protection of the environment.



Provinces are allowed to withdraw areas from the normal cateo/mina process. These lands may be held directly by the province or assigned to provincial companies for study or exploration and development.



A party wishing to commence or modify any mining-related activity as defined by the Mining Code, including prospecting, exploration, exploitation, development, preparation, extraction, and storage of mineral substances, as well as property abandonment or mine closure activity, must prepare and submit to the Provincial Environmental Management Unit (PEMU) an Informe de Impacto Ambiental or Environmental Impact Assessment (EIA) prior to commencing the work. Each EIA must describe the nature of the proposed work, its potential risk to the environment, and the measures that will be taken to mitigate that risk. The PEMU has a 60-day period to review and either approve or reject the EIA. However, the EIA is not considered to be automatically approved if the PEMU has not responded within that period. If the PEMU deems that the EIA does not have sufficient content or scope, the party submitting the EIA is granted a 30-day period in which to resubmit the document.



If accepted by the PEMU, the EIA is used as the basis to create a Declaración de Impacto Ambiental or Declaration of Environmental Impact (DEI) to which the party must swear to uphold during the mining-related activity in question. The DEI must be updated every two years, with a report on the results of the protection measures taken. If protection measures are deemed inadequate, additional environmental protection may be required. Mine operators are liable for environmental damage. Sanctions and penalties for non-compliance to the DEI are outlined in the Environmental Protection Section of the Mining Code, and may include warnings, fines, suspension of environmental Quality Certification, restoration of the environment, temporary or permanent closure of activities, and removal of authorization to conduct mining-related activities.



Further to the provisions of the Mining Code on Environmental Protection, mining activities are also subject to other environmental regulations issued at the federal and provincial level (from the province in where such activities are carried out).



All mineral rights described above are considered forms of  proprietary rights and can be sold, leased or assigned to third parties on a commercial basis. As described before, cateos and minas can be forfeited if minimum work and investments requirements are not performed or if annual payments are not made. Generally, notice and an opportunity to cure defaults is provided to the owner of such rights.



RISK FACTORS

We are subject to a cash call in respect of the San José Project and our failure to satisfy this request could cause our interest in the San José Project to decrease.

The OJVA provides that the Board of MSC may elect to raise additional funds by issuing shares of MSC, and in such event, each shareholder of MSC shall have a pre-emptive right to subscribe and pay for its pro rata share of such additional shares of MSC.  Historically, MSCs operations have been financed in this manner.  Any shares not purchased by Minera Andes pursuant to its pre-emptive right may be purchased by Hochschild.  Accordingly, in the event of a cash call by MSC, financed by share subscriptions, a failure by Minera Andes to exercise its pre-emptive right, in full or at all, may result in a reduction of its interest in the San José Project.



On December 19, 2008, the Corporation received a cash call from MSC, to finance further expansion and development of the San José Project.  The Corporations share of this cash call is US$11.3 million.  Under the terms of the OJVA, the cash call is due to be paid on February 17, 2009.  The Corporations current cash balance is approximately US$2.5 million.  As a result, the Corporation is currently unable to pay its share of this cash call.



21



---

There can be no assurance that the Corporation will be successful in obtaining the funds required to satisfy this cash call when due and that its interest in the San José Project will not be reduced as a result.



The Corporation does not currently have sufficient cash to repay the Bank Loan.

A portion of the Bank Loan is due to be repaid in March 2009.  The amount to be repaid in March 2009 is US$7.5 million.  A further US$10 million is due to be repaid in September 2009.  The obligations to Macquarie under the Bank Loan are, secured by, all of the present and after-acquired assets of the Corporation.  There can be no assurance that the Corporation will have sufficient funds with which to make the scheduled repayments under the Bank Loan, as and when due.  Failure to make any such repayments as and when required is an event of default under the Macquarie Credit Agreement.



A failure to repay the amount owing under the Macquarie Credit Agreement would have an adverse affect on the Corporation and its financial position.



We are currently in default under the Bank Loan.

Under the terms of the Macquarie Credit Agreement, pursuant to which Macquarie has advanced the Corporation the principal sum of US$17.5 million, the Corporation is required to maintain cash and cash equivalents at least equal to the sum of all outstanding cash calls made by MSC to the Corporation plus certain other amounts.  The Corporations current cash balance is approximately US$2.5 million.  Accordingly, the Corporation is currently not in compliance with terms of the Bank Loan, and Macquarie is entitled to accelerate the payment of amounts due thereunder, though it has not done so as at the date of this AIF.



Global economic conditions combined with our financial position could make financing our operations and business strategy more difficult.

For the three month period ended September 30, 2008, the Corporation had a working capital deficiency of $10.3 million and a net loss of $8.2 million for the year ended December 31, 2007 compared to a net loss of $10.8 million for the year ended December 31, 2006.  There is no assurance that we will be able to remedy our working capital deficiency or that we will not continue to incur losses.  Numerous factors, including declining metal prices, lower than expected ore grades or higher than expected  operating  costs  (including increased commodity prices), and impairment write-offs of mine property and/or exploration property costs, could cause us to continue to be unprofitable in the future.  In addition, as at December 31, 2007 we had total consolidated debt and liabilities of $68.7 million.



Current global financial conditions have been subject to increased volatility and numerous financial institutions have either gone into bankruptcy or have had to be rescued by governmental authorities.  Access to public financing has been negatively impacted by both sub-prime mortgages and the liquidity crisis affecting the asset-backed commercial paper market.



In the short term, these factors, combined with our financial position, may impact our ability to obtain equity or debt financing in the future and, if obtained, on terms favourable to us.  In the longer term these factors, combined with our financial positioncould have important consequences, including the following:



·

increasing our vulnerability to general adverse economic and industry conditions;

·

limiting our ability to obtain additional financing to fund future working capital, capital expenditures, operating and exploration costs and other general corporate requirements;

·

requiring us to dedicate a significant portion of our cash flow from operations, anticipated from the San José Project, to make debt service payments, which would reduce our ability to fund working capital, capital expenditures, operating and exploration costs and other general corporate requirements;

·

limiting our flexibility in planning for, or reacting to, changes in our business and the industry; and

·

placing us at a disadvantage when compared to our competitors that have less debt relative to their market capitalization.



22



---

Any cost overruns or cash shortfall at the San José  Project could result in further investment by us.

MSC currently anticipates that cash from operations at the San José  Project will be sufficient to finance operations and planned capital expenditures.  There can be no assurance that actual capital costs will not exceed budgeted capital costs, that cash from operations will not meet MSCs forecast or that other capital expenditures will not be approved by MSC for the San José Project.  If, and to the extent, cash from operations is insufficient to fund cost-overruns, sales or production are lower than expected or an additional capital project initiated, additional investment by the shareholders of MSC (including the Corporation) may be required.  Any requirement for additional investment, by share subscription or loan or otherwise, could adversely affect the Corporations financial position.

We do not control (jointly or otherwise) the San José Project and have no control over the timing or amount of future cash calls.

We hold 49% of the voting shares of MSC and Hochschild holds the balance.  The Board of MSC consists of five members, only two of which are nominees of Minera Andes.  Hochschild is entitled to appoint the balance of the members of the Board of Directors of MSC.  The OJVA grants us a veto in respect of certain and very limited matters regarding the affairs of MSC and the operation of the San José Project.  Accordingly, MSC and the San José Project are under the control of Hochschild.



As a result, we have a limited, if any, ability to control the timing or amount of cash calls or any other matter relating to the management of MSC and the San José Project and decisions made in that regard may have an adverse effect on our operations and financial position.  There can be no assurance that if made, we will have the funds available to satisfy any such cash call when due and that our interest in the San José Project will not be reduced as a result.



A substantial or prolonged decline in metal prices, particularly gold, silver or copper, would have a material adverse effect on us.

The price of our common shares, our financial results, and our exploration, development and mining activities have previously been, and may in the future be, significantly adversely affected by declines in metal prices. Metal prices are volatile and are affected by numerous factors beyond our control such as the sale or purchase of metals by various central banks and financial institutions, interest rates, exchange rates, inflation or deflation, fluctuation in the value of the United States dollar and foreign currencies, global and regional supply and demand, and the political and economic conditions of major mining countries throughout the world. Any future serious drop in the price of metals could adversely impact our future revenues, profits and cash flows. In particular, sustained low metal prices could:



·

reduce cash from operations at the San José Project, requiring additional investment by, or loan from, the Corporation to remedy a cash shortfall;

·

cause suspension of the development of the mine at the San José Project;

·

reduce or eliminate the benefit of growth opportunities anticipated from the development of our Los Azules Project;

·

reduce or eliminate our ability to obtain credit;

·

cause us to be unable to fulfill our debt payment obligations;

·

force us to lose our interest in, or to sell, all or some of our properties;

·

halt or delay the development of new projects; and

·

reduce funds available for exploration.



Furthermore, declining commodity prices can impact our operations by requiring a reassessment of the feasibility of any of our projects.  Even if the project is ultimately determined to be economically viable, the need to conduct such a reassessment may cause substantial delays or may interrupt operations until the reassessment can be completed.  In addition, mineral reserve calculations and life-of-mine plans using significantly lower metal prices could result in reduced estimates of mineral reserves and non-reserve mineral resources and in material write-downs of our investment in mining properties and increased amortization, reclamation and closure charges.



23



---

We have no operational cash flow and are dependent on third party financing.

Although production at the San José Project commenced in 2007, we currently have no source of operational cash flow.  The amount and timing of distributions of cash by MSC is to be set out in a definitive agreement between the Corporation and Hochschild.  Such agreement has not yet been finalized.  In any event, the amount and timing of cash to be received from the San José Project will be subject to the approval of the shareholders of MSC, in which we have a minority (49%) interest.  However, the parties have agreed that the Project Loan plus accrued interest will be repaid by MSC prior to the distributions of any amounts to the shareholders of MSC (including the Corporation).  Accordingly, there can be no assurance if and when cash distributions will be received from MSC, or if such distributions will be sufficient by themselves to fund our continuing exploration and development activities.



As a result we depend on third party financing to pay the existing cash call and the amount due under the Bank Loan in March 2009, and we may continue to depend on third party financing to pay a future cash call by MSC, fund future working capital, capital expenditures, operating and exploration costs and other general corporate requirements.  Failure to obtain sufficient financing, as and when required, may result in a delay or indefinite postponement of exploration, development or production on any or all of its properties or even a loss of our assets.  There can be no assurance that additional capital or other types of financing will be available or that, if available, the terms of such financing will be favourable to the Corporation.



The Macquarie Credit Agreement contains restrictions and other covenants.

The Macquarie Credit Agreement contains covenants and imposes restrictions on the Corporations ability to complete certain transactions.  For example, the Macquarie Credit Agreement requires that the Corporation maintain certain cash and cash equivalent reserves and prohibits the Corporation from paying any dividends or making any other distributions to its shareholders while amounts are outstanding thereunder.



In addition, the Macquarie Credit Agreement contains a covenant that Minera Andes maintain its shareholding in MSC at 49%.  Failure by Minera Andes to participate in the existing and/or a future cash call by MSC could result in a reduction in the Corporations shareholding in MSC below 49%.  There can be no assurance that the Corporation will be in a position to finance the outstanding cash call by MSC referred to above or a future cash call by MSC.



A breach by the Corporation of any covenant or restriction in the Macquarie Credit Agreement including a failure by Minera Andes to maintain its 49% shareholding in MSC will constitute an event of default under the Macquarie Credit Facility, entitling Macquarie to accelerate the payment of amounts due thereunder.



An obligation to repay the amount owing under the Macquarie Credit Agreement before its stated maturity, could have an adverse affect on the Corporation and its financial position.



We are subject to interest rate fluctuations.

The Corporations various credit arrangements accrue interest at variable rates.  Both the Project Loan and the Bank Loan accrue interest at a rate that fluctuates with LIBOR. We have not entered into any agreements to hedge against unfavorable changes in interest rates, but may in the future actively manage our exposure to interest rate risk.  As a result, the Corporation is exposed to adverse interest rate movements that could have a material adverse impact on profitability and cash flow.



We are subject to fluctuations in currency exchange rates, which could materially adversely affect our financial position.

We maintain most of our working capital in Canadian and United States dollars.  However, a significant portion of our operating costs are incurred in Argentinean pesos.  Accordingly, we are subject to fluctuations in the rates of currency exchange between the Canadian, United States dollar and Argentinean peso, and these fluctuations could materially affect our financial position and results of operations as construction, development and other costs may be higher than anticipated.  The costs of goods and services could increase due to changes in the value of the Canadian dollar, the United States dollar, or the Argentinean peso.  Consequently, operation and development of our properties might be more costly than we anticipate.

The Corporation is subject to risks relating to economic and political instability in Argentina.



All of the Corporations material properties are located in Argentina. There are risks relating to an uncertain or unpredictable political and economic environment in Argentina.



During an economic crisis in 2002 and 2003, Argentina defaulted on foreign debt repayments and on the repayment on a number of official loans to multinational organizations. In addition, the Government has renegotiated or defaulted on contractual arrangements.



In January 2008, the Argentinean Government reassessed its policy and practice in respect of export duties and began levying export duties on mining companies operating in the country.  Although this particular change does not affect the Corporation as its fiscal stability agreement explicitly fixes export duties at 5% for doré bars and 10% for concentrates, there can be no assurance that the Argentinean Government will not unilaterally take other action which could have a material adversely effect the Corporations interests in Argentina, including in particular the San José Project.



There also is the risk of political violence and increased social tension in Argentina and Argentina has experienced periods of civil unrest, crime and labour unrest.



Certain political and economic events such as acts or failures to act by a government authority in Argentina, and acts of political violence in Argentina, could have a material adverse effect on the Corporations ability to operate.



Estimates of mineral reserves and mineral resources could be inaccurate.

The figures for mineral reserves and mineral resources contained in this AIF are estimates only and no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that mineral reserves can be mined or processed profitably.  There are numerous uncertainties inherent in estimating proven and probable mineral reserves and measured, indicated and inferred mineral resources, including many factors beyond our control. The estimation of reserves and resources is a subjective process and the accuracy of such estimates is a function of the quantity and quality of available data and of the assumptions made and judgments used in engineering and geological interpretation, which could prove to be unreliable. These estimates may not be accurate and there can be no assurance that mineral reserves and resources can be mined or processed profitably.  Short-term operating factors relating to the mineral reserves, such as the need for orderly development of the ore bodies or the processing of new or different ore grades, may cause the mining operation to be unprofitable in any particular accounting period. In addition, there can be no assurance that gold, silver or copper recoveries in small scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production.



Fluctuation in metal prices, results of drilling, metallurgical testing, production costs or recovery sales, and the evaluation of mine plans subsequent to the date of any estimate could require revision of reserve and resource estimates. The volume and grade of mineral reserves mined and processed and recovery rates might not be the same as currently anticipated. Any material reduction in estimates of mineral reserves and resources, or our ability to extract these mineral reserves and resources, could have a material adverse effect on our further cash flow, results of operation and financial condition.



Mining activities are subject to a number of risks and hazards that may result in damage to property, delays and possible legal liability.

The Corporations business operations are subject to risks and hazards inherent in the mining industry.  The exploration for and the development of mineral deposits involves significant risks, including:



·

environmental hazards;

·

discharge of pollutants or hazardous chemicals;

·

industrial accidents;

·

labor disputes and shortages;

·

supply and shipping problems and delays;

·

shortage of equipment and contractor availability;



25



---

·

difficulty in applying technology such as bio-oxidation processing;

·

unusual or unexpected geological or operating conditions;

·

cave-ins of underground workings;

·

failure of dams;

·

fire;

·

marine and transit damage and/or loss;

·

changes in the regulatory environment; and

·

natural phenomena such as inclement weather conditions, floods and earthquakes.



These or other occurrences could result in damage to, or destruction of, mineral properties or production facilities, personal injury or death, environmental damage, delays in mining, delayed production, monetary losses and possible legal liability. We could (directly or through a project in which we have an interest) incur liabilities as a result of pollution and other casualties. Satisfying such liabilities could be very costly and could have a material adverse effect on our financial position and results of operations.



We need to continually discover, develop or acquire additional mineral properties and a failure to do so would adversely affect our business and financial position in the future.

Mineral exploration, in which we are significantly engaged at this time, is highly speculative, involves substantial expenditures, and is frequently unsuccessful.  Few prospects that are explored end up being ultimately developed into producing mines. To the extent that we continue to be involved in exploration, the long-term success of our operations will be related to the cost and success of our exploration programs. We cannot assure you that our exploration efforts will be successful. The success of exploration is determined in part on the following factors:



·

the identification of potential mineralization based on superficial analysis;

·

availability of prospective land;

·

availability of government-granted exploration and exploitation permits;

·

the quality of our management and our geological and technical  expertise; and

·

the capital available for exploration and development.



Substantial expenditures are required to determine if a project has economically mineable mineralization. It could take several years to establish proven and probable mineral reserves and to develop and construct mining and processing facilities. As a result of these uncertainties, we cannot assure you that current and future exploration programs will result in the discovery of mineral reserves, the expansion of existing mineral reserves and the development of mines.



Whether income will result from projects undergoing exploration and development programs depends on the successful establishment of mining operations.  Factors including costs, actual mineralization, consistency and reliability of ore grades and commodity prices affect successful development.



Developed mines have limited lives based on proven and probable mineral reserves.  The ability to maintain or increase annual production depends in significant part on the identification of new reserves and resources.



Regulatory and permitting requirements significantly affect our mining operations and may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our activities are subject to numerous environmental laws, regulations and permitting requirements that can delay production and adversely affect operating and development costs.  Compliance with existing regulations governing the discharge of materials into the environment, or otherwise relating to environmental protection, in the jurisdictions where we have projects may have a material adverse effect on our exploration activities, results of operations and competitive position.  New or expanded regulations, if adopted, could affect the exploration or development of our projects or otherwise have a material adverse effect on our operations.  To the extent such approvals are required and not obtained, the Corporation may be curtailed or prohibited from continuing its mining operations or from proceeding with planned exploration or development of mineral properties, or projected production commencement dates, production amounts and costs could be adversely affected.



26



---

Mining operations require mining and other permits from the government.  These permits may not be issued on a timely basis or at all, and such permits, when issued, may be subject to requirements or conditions with which it is burdensome or expensive to comply.  Furthermore, there is no assurance that delays will not occur in connection with obtaining all necessary renewals of existing permits, additional permits for any possible future changes to operations, or additional permits associated with new legislation.



Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, including orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment, or remedial actions. Parties engaged in mining operations or in the exploration or development of mineral properties may be required to compensate those suffering loss or damage by reason of the mining activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations.  Due to an increased level of non-governmental organization activity targeting the mining industry, the potential for the government to delay the issuance of permits or impose new requirements or conditions upon mining operations may be increased.  Environmental legislation is evolving in a manner which will likely require strict standards and enforcement, increased time and penalty for non-compliance, more stringent environmental assessments or proposed projects and a heightened degree of responsibilities for companies and their officers, directors and employees.  Any changes in government policies may be costly to comply with and may delay mining operations. The exact nature of other environmental control problems, if any, which we may encounter in the future, cannot be predicted, primarily because of the changing character of environmental requirements that may be enacted within various jurisdictions. To the extent that we are subject to any such changes, they may have a material adverse effect on our operations.  Environmental hazards may also exist on the properties on which the Corporation holds interests which are unknown to the Corporation at present and which have been caused by previous or existing owners or operators of the properties.



As a result of the foregoing risks, project expenditures, production quantities and rates and cash operating costs, among other things, could be materially and adversely affected and could differ materially from anticipated expenditures, production quantities and rates, and costs. In addition, estimated production dates could be delayed materially. Any such events could materially and adversely affect our business, financial condition, results of operations and cash flows.



We currently do not have a hedging program.  Implementation of a hedging program might be unsuccessful and incur losses.

We do not have a hedging program nor do we have plans to engage in hedging activities in the future.  Hedging activities are intended to protect a company from fluctuations in the price of gold and to minimize the effect of declines in metal prices or results of operations for a period of time.  However, if we do implement a hedging program in the future, we may be prevented from fully benefiting from higher spot market metal prices to the extent that production is hedged.



We are subject to litigation risks.

All industries, including the mining industry, are subject to legal claims, with and without merit. Defence and settlement costs can be substantial, even with respect to claims that have no merit. Due to the inherent uncertainty of the litigation process, the resolution of any particular legal proceeding could have a material adverse effect on our financial position and results of operations.



We face competition from other mining companies in connection with the acquisition of properties.

We face strong competition from other mining companies in connection with the acquisition of properties producing, or capable of producing, precious metals. The majority of these companies have greater financial resources, operational experience and technical capabilities.  As a result of this competition, we might be unable to maintain or acquire attractive mining properties on terms we consider acceptable or at all.  Consequently, our revenues, operations and financial condition could be materially adversely affected.



27



---

Title to our mineral properties could be challenged.

We periodically confirm the validity of our title to, or contract rights with respect to, each mineral property in which we have a material interest. However, we cannot guarantee that title to our properties will not be challenged.  Our mineral properties could be subject to prior unregistered agreements, transfers or claims, and title could be affected by, among other things, undetected defects. In addition, we might be unable to operate our properties as permitted or to enforce our rights with respect to our properties.



Our insurance coverage could be insufficient.

The Corporations business is subject to a number of risks and hazards generally, including adverse environmental conditions, industrial accidents, labour disputes, unusual or unexpected geological conditions, ground or slope failures, cave-ins, changes in the regulatory environment and natural phenomena such as inclement weather conditions, floods, hurricanes and earthquakes. Such occurrences could result in damage to mineral properties or production facilities, personal injury or death, environmental damage to the Corporations properties or the properties of others, delays in mining, monetary losses and possible legal liability.



Although the Corporation maintains insurance to protect against certain risks in such amounts as it considers to be reasonable, its insurance will not cover all the potential risks associated with a mining companys operations.  The Corporation may also be unable to maintain insurance to cover these risks at economically feasible premiums.  Insurance coverage may not continue to be available or may not be adequate to cover any resulting liability.  Moreover, insurance against risks such as loss of title to mineral property, environmental pollution, or other hazards as a result of exploration and production is not generally available to the Corporation or to other companies in the mining industry on acceptable terms. The Corporation might also become subject to liability for pollution or other hazards which may not be insured against or which the Corporation may elect not to insure against because of premium costs or other reasons. Losses from these events may cause the Corporation to incur significant costs that could have a material adverse effect upon its financial performance and results of operations.



Any limitations on the transfer of cash or other assets between the Corporation and its subsidiaries or joint venture partners could adversely impact the available credit, valuation and stock price of the Corporation.

Minera Andes is a Canadian company that conducts operations through foreign (principally Argentinean) subsidiaries and joint ventures, and substantially all of our assets consist of equity in these entities. Accordingly, any limitation on the transfer of cash or other assets between the parent corporation and these entities, or among these entities, could restrict our ability to fund our operations efficiently.  Any such limitations, or the perception that such limitations might exist now or in the future, could have an adverse impact on available credit and our valuation and stock price.



We depend on the services of key executives.

We are dependent on the services of key executives including our President and a small number of highly skilled and experienced executives and personnel.  Due to the relatively small size of our management team, the loss of these persons or our inability to attract and retain additional highly skilled employees could adversely affect the exploration and development of our properties, which could have a material adverse effect on our business and future operations.  We do not have key person insurance.



The market price of our common shares could experience volatility and could decline significantly.

Our common shares are listed on the TSX under the symbol MAI and are quoted on the NASD OTC Bulletin Board under the symbol MNEAF. Securities of small-cap companies have experienced substantial volatility in the past, often based on factors unrelated to the financial performance or prospects of the companies involved.  These factors include macroeconomic developments in North America and globally and market perceptions of the attractiveness of particular industries.  Our share price is also likely to be significantly affected by short-term changes in metal prices or in our financial condition or results of operations as reflected in our quarterly earnings reports.  Other factors unrelated to our performance that could have an effect on the price of our common shares include the following:



28



---

·

the extent of analytical coverage available to investors concerning our business could be limited if investment banks with research capabilities do not follow our securities;

·

the trading volume and general market interest in our securities could affect an investor's ability to trade significant numbers of common shares; and

·

the size of the public float in our common shares may limit the ability of some institutions to invest in our securities.



As a result of any of these factors, the market price of our common shares at any given point in time might not accurately reflect our long-term value.  Securities class action litigation often has been brought against companies following periods of volatility in the market price of their securities.  We could in the future be the target of similar litigation.  Securities litigation could result in substantial costs and damages and divert management's attention and resources.



Investors could have difficulty or be unable to enforce certain civil liabilities against us, certain of our directors and our experts.

Minera Andes is a Canadian corporation.  Substantially all of our assets are located outside of Canada and the United States, and our head office is located in the United States.  It might not be possible for investors to collect judgments obtained in Canadian or United States courts predicated on the civil liability provisions of Canadian or U.S. securities legislation.  Execution by United States courts of any judgment obtained against us or any of the directors, executive officers or experts in the United States courts would be limited to our assets or the assets of such persons or corporations, as the case might be, in the United States.  The enforceability in Canada of United States of judgments or liabilities in original actions in Canadian courts predicated solely upon the civil liability provisions of the federal securities laws of the United States is doubtful.



The existence of outstanding rights to purchase or acquire common shares could impair our ability to raise capital.

As of the date of this AIF, approximately 33 million common shares are issuable on exercise of warrants, options, agents compensation options and agents compensation warrants. During the life of the warrants, options, agents compensation options and agents compensation warrants, the holders are given an opportunity to profit from a rise in the market price of common shares, with a resulting dilution in the interest of the other shareholders. Our ability to obtain additional financing during the period such rights are outstanding could be adversely affected, and the existence of the rights could have an adverse effect on the price of our common shares.  The holders of the warrants and options can be expected to exercise or convert them at a time when we would, in all likelihood, be able to obtain any needed capital by a new offering of securities on terms more favorable than those provided by the outstanding rights.



We may not pay dividends on our common shares.

We have never paid cash dividends on our common shares. We are currently prohibited from making any distribution to shareholders, until such time as the Bank Loan is repaid.  As a result, investors will have to rely on capital appreciation, if any, to earn a return on their investment in our common shares in the foreseeable future.



Sales of substantial amounts of our securities may have an adverse effect on the market price of our securities.

Sales of a large number of common shares in the public markets, or the potential for such sales, could decrease the trading price of the common shares and could impair the Corporations ability to raise capital through future sales of common shares.

SAN JOSé PROJECT

Unless otherwise stated, the information in this section is based on the San José Technical Report.  In accordance with instruction (ii) of Item 5.4 of 51-102F2, a form prescribed by National Instrument 51-102Continuous Disclosure Obligations (NI 51-102), the summary contained in the San José Technical Report is reproduced below.



Property Setting

The Property is situated in the Province of Santa Cruz, southern Argentina, 1,750 km southsouthwest of the capital city, Buenos Aires, and 230 km southwest of the Atlantic coast port city of Comodoro Rivadavia.  Access to the Property from Comodoro Rivadavia takes about 4.5 hours and is mostly along paved highways with the final 32 km along a well-maintained gravel road.  Elevations on the Property range between approximately 300 and 700 masl.



Topography is gently rolling, with a few deeply incised valleys.  The climate is arid to semi-arid with short warm summers, and winters with temperatures commonly below 0oC.  Mining and exploration can continue year round in this part of Argentina.



Most of the Property area is uninhabited; it is however, used by local farmers for sheep and cattle grazing.



Tenure and Agreements

The Project is operated as a joint venture between Minera Andes S.A. (49%) and Hochschild Mining plc (51%), through the holding company Minera Santa Cruz S.A (MSC).



The Project covers 50,491 ha, comprising 46 contiguous Mining Claims (8 Minas or approved mining claims; and 38 Manifestations or claims that are in the application process for mining claim status) and one exploration claim (cateo).  Mineral Reserves are hosted on Minas El Pluma E3 and El Pluma 4.  The claims are all in good standing, with the appropriate annual holding costs paid.  MSC holds the surface rights to the San José Estancia, where the mine and associated infrastructure are constructed and the La Carmancita Estancia, which provides right of way access between the mine and closest paved highway.



MSC retained Vector Peru S.A. to complete an EIA covering the Project in 2004.   Approval was received from the Santa Cruz Provincial Department of Mining (DPM) on 1 March 2006.  MSC has received an Environmental Quality Certificate from the DPM for 2006 and is currently awaiting approval for the 2007 certificate from the DPM.  All other permits required to operate the mine are in place.



Previous Work

There is no formally-recorded exploration on the project prior to Minera Andes work during 1997 to 2001.  Surface exploration during this period resulted in the discovery of the Huevos Verdes and Saavedra West epithermal vein and breccia systems.  Hochschild Mining plc (until November 2006, a private Peruvian group named Mauricio Hochschild & Cia. Ltda) joint ventured into the property in 2001.



In 2004, a Feasibility Study was commissioned to evaluate the economics of an underground mining operation on the Huevos Verdes and Frea Veins.  The Feasibility Study envisaged a 750 t/d operation over a 4.3 year mine-life, using mechanized cut-and-fill mining as the primary mining method, supplemented by conventional cut-and-fill mining where the vein width was not sufficient to permit entry of the mechanized equipment.  Waste rock was to be used as backfill in the mining operation.  San José mineralization was to be processed on-site using conventional crushing, grinding, flotation and concentrate cyanidation leach technology, with cyanide recovery and destruction.  Gold and silver was planned to be recovered by standard Merrill Crowe zinc precipitation and refined to produce doré bars.



30



---

The Feasibility Study was completed in October 2005 and in March 2006 led to a positive development decision, and commencement of commercial production in late June 2007.  The veins included in the current mine plan are the Huevos Verde Veins, comprising three northwest aligned, discontinuous zones: Huevos Verdes North (HVN), Huevos Verdes Central (HVC) and Huevos Verdes South (HVS), the Frea vein and the Kospi vein.  The three main veins HV, Frea and Kospi vein are located within about a 2 km radius of each other.



Geology and Mineralization



The San José Project is located in the extreme northwest corner of the 60,000 square kilometre Deseado Massif, in Patagonia, Southern Argentina.  Jurassic volcanic rocks in the massif host numerous widely-distributed clusters of gold and silver bearing quartz veins such as Cerro Vanguardia, Martha, Manantial Espejo and San José.  The Deseado Massif consists of Palaeozoic low-grade metamorphic basement rocks unconformably overlain by an extensive sequence of Middle to Upper Jurassic-aged andesitic to rhyolitic volcanic and volcanoclastic rocks.  The Jurassic rocks are divided into the Bajo Pobre Formation, predominantly of intermediate composition, and the felsic Bahia Laura Group, which discordantly overlies the Bajo Pobre Formation.  The Bahia Laura Group is in turn subdivided into the Chon Aike Formation (dominantly ignimbrites) and the La Matilde Formation (dominantly volcaniclastic rocks).  These units are overlain by Cretaceous-aged tuffs and siliciclastic sediments of the Castillo Formation, which were deposited in small fault-controlled basins concentrated along the northern and southern margins of the Deseado Massif.  Overlying these are Tertiary-aged flood basalts of the Alma Gaucha Formation, which are widespread and cover much of the northwestern and central portions of the massif.



Most mineralization and exploration targets on the San José Property are hosted in the Bajo Pobre Formation, and to a lesser degree, the Chon Aike Formation.  Occurrences have also been documented in the Cretaceous-aged rocks.  Targets other than the principal veins under production and development and their strike extensions, include the Odin (A and B), Ayelen, Flor, HV West, Kospi 1, Kospi South, Lourdes, Frigga, Aguas Vivas, Roadside, and Portuguese West.  An exploration program is currently underway to explore these targets.



Mineralization is developed in low-sulphidation epithermal quartz vein, breccia and stockwork systems, and consists of banded to mottled ginguro quartz with irregular sulphide bands, mineralized by fine-grained argentite, pyrite and occasionally arsenopyrite.  Sulphide percentages vary from vein to vein, but average from <1% to 5%.



Vein lengths and thicknesses at the principal veins are variable, including 400 m of strike and 0.5 m to 4.0 m thicknesses at HVN; 520 m of strike and 0.5 m to 3.0 m thickness at HVS; 400 m of strike and 0.5 m to 5.0 m thickness at HVC; 600 m of strike and 0.5 m to 7.0 m thickness at Frea; and 1,100 m of strike and 0.3 m to 9.5 m thickness at Kospi.



The mineralized systems are preferentially developed in normal-sinistral faults striking 330° to 340°, and conjugate dextral faults striking ~300°.  Fault slickensides at Huevos Verdes rake from 0° to 90° indicating that fault-veins range from pure strike-slip to dip-slip.  Veins have variable dips, ranging from 42o and 75o to the northeast in the Huevos Verde and Frea veins to 65o to the southwest in the Kospi vein.



Alteration comprises a narrow halo of silicification around veins and fractures, surrounded by an extensive zone of intermediate argillic (often with an argillic overprint) alteration that is mixed with phyllic alteration.  The intermediate alteration zone is in turn surrounded by a much more extensive zone of propylitic alteration.



Drilling and Sampling

Since 1998, a total of approximately 98,744 m in 583 exploration holes has been drilled on the various zones and targets throughout the Property.  Of these, 493 of the holes are core (89,651 m) and 90 holes (9,093 m) are reverse circulation (RC).  In addition there are more than 6,500 underground channel samples in roughly 2,000 sample lines from the HVN, HVS, and Frea veins, and more than 170 surface trenches.



A total of 472 drill holes and trenches (76,478 m) and 2,733 channel samples and are used to support the mineral resource estimates at HVN, HVS, HVC, HVrml, Frea and Kospi.

Data Verification

Data were verified in four phases, dating from 2001 to 2007.  Verification included laboratory visits (2001 and 2005), independent core sampling (2001 and 2004), drill collar location verification (2004 and 2007), down hole survey review (2005 and 2007), density review (2005 and 2007), geological interpretation review (2005 and 2007), database auditing (2005 and 2007).  In addition, reviews of the QA/QC data (blanks, standards, pulps and duplicates) were undertaken in 2004 and 2007.  The checks indicated that most of the data are sufficiently free from error to support resource estimation; however, underground channel-chip sample precision continues to be poor, mainly due to difficult sampling conditions and, possibly, to inadequate sampling procedures.  In addition, since the last Technical Report in 2005, an incomplete QA/QC program has been in place, lacking sufficient coverage of coarse and pulp duplicates.  As a result, AMEC is unable to comment on sub-sampling and analytical precision; however, Au and Ag accuracy are within acceptable limits.



Mineral Resources

Mineral Resources, as of 30 June 2007, were estimated by Hector Aspajo, MAusIMM and Abel Puerta, MAusIMM, (MSC), and audited and adjusted by Emmanuel Henry, MAusIMM (CP) from AMEC.



Databases were constructed and maintained using the GEMM system, a proprietary MSC database.  All assays were composited to full-width vein intercepts, and were not weighted with respect to vein intercept lengths.  Each intercept thus represents a single composite. Composites and 3-dimensional solid models were constructed utilizing MineSight® commercial mine modelling software.  Grade estimations for gold and silver were completed utilizing ordinary kriging methods via MineSight routines.  Block grades were estimated within a marginal cut-off shell equating to $US45/t



A geological model was completed for each vein, containing two solids (domains); one representing the quartz vein and the other restricted to a US$45/t marginal economic cut-off, which is internal to the quartz vein domain.  The resource model was then constrained to the latter domain.  The blocks were classified as Measured, Indicated or Inferred, in accordance with the Australasian 2004 JORC Code, based on the variogram ranges and the index of relative variability.  These classifications were reconciled with 2005 CIM definitions.  During the audit AMEC encountered several tabulation errors in the Huevos Verdes estimates and made the appropriate corrections.  AMEC has re-tabulated the mineral resources and the restated CIM-definition-compliant resource estimates for the overall San José Project as shown in Table 1-1.  AMEC also detected a high bias in the silver estimates at Huevos Verdes South in the order of 14%, which was not corrected.



The mineral resources were estimated using the following assumptions within a marginal cut-off shell equating to $US45/t or a silver-equivalent cut-off grade of 176 g/t Ag-equiv:



·

gold grade top-cuts:  65 g/t HVS; 10 g/t HVC; 50 g/t HVN; 50 g/t HVS Rml; 50 g/t Frea; 30 g/t Kospi

·

silver grade top-cuts: 6,000 g/t HVS; 500 g/t HVC; 4,000 g/t HVN; 5,000 HVS Rml ; 3,000 g/t Frea; 2,700 g/t Kospi

·

density:  2.595 t/m3  for all Huevos Verde zones, 2.611 t/m3 for Frea and Kospi

·

gold mill recovery:  89.65%

·

silver mill recovery:  90.49%

·

gold commercial recovery: 99.68%

·

silver commercial recovery: 99.75%

·

gold price:  US$500.00/oz

·

silver price:  US$9.00/oz

The Measured and Indicated Mineral Resources has grown by 586 kt, 8,185,000 ounces of silver and 125,000 ounces of gold since the December 31, 2006 statement (Table 1-2).  This is primarily the result of additional drilling.

Mineral Reserves

Mineral reserves at the HVN, HVC, HVS, Frea and Kospi Veins were estimated by Abel Puerta MAusIMM (MHC) and reviewed/adjusted by Pierre Rocque, P. Eng from AMEC (Table 1-3).  The estimate was completed in accordance with CIM Mineral Resource and Mineral Reserve Standards.

Reserve parameters utilized by MHC were modified as required, and the following parameters support the reserves estimates:

·

minimum mining widths of 1.0 m for conventional cut-and-fill stopes and 1.5 m for mechanized cut-and-fill stopes

·

unplanned dilution of 12% (adjusted from 15% used in the Feasibility Study)

·

mining recovery of 95% (adjusted from 98% used by MSC)

·

stopes outlined according to a break-even cut-off value of US$94/t and also by consideration of key mining criteria such as width, equipment selection and stope access

·

recovery figures used against sill pillar reserves of 25% dilution and 75% mining recovery (not considered in MSC estimate)

·

10 m crown pillar

·

Mineral Reserves shown above are inclusive of the Mineral Resources shown on Table 1-1.



Mineral Reserves are considered sufficient to support a 9 year mine-life at an average mining rate of 750 t/d.



Mine Development and Mine Plan

The Huevos Verdes complex and the Frea vein are accessed via two separate declines from surface.  The Frea vein is currently being mined by the MCF (mechanized cut-and-fill) method whereas portions of the HV vein are scheduled to be mined by the CF (conventional cut-and-fill) method due to narrower vein widths than at Frea.  It is anticipated that the same mine design will be implemented for the Kospi deposit, once the characteristics of the vein are better understood.



The mining plan provided by MSC for the Huevos Verdes and Frea veins is based on minimum mining widths of 1.0 m for conventional cut-and-fill stopes and 1.5 m for mechanized cut-and-fill stopes.  A 1-boom jumbo is used for development and production drilling in wider stopes (i.e. over 1.5 m); otherwise, hand-held drills (i.e. stopers) are used for production drilling.  Ore haulage to the ore passes is by scooptrams ranging from 1.5 yd3 to 4.0 yd3.  Current haulage is performed by 20 t trucks via the ramp to surface where it is transported directly from the mine to the processing plant.



Waste rock from development will be used for backfill in the cut-and-fill mining.  Later in the mine life, when a shortage of waste rock for backfill occurs, then borrow surface till will be used for backfill.



34



---

Fresh air is distributed throughout the mine via a pull ventilation system, which uses one fan per vein to pull the air into the mine through near-vertical raise-bored raises and the declines.



According to the RMR classification system, both the HVN and HVS zones show Poor to Fair quality rockmass designations and the Frea zone ranges from Fair to Good.  The most competent ground occurs in the ore body, then in the footwall, and finally in the hanging wall.  Ground conditions tend to improve with increasing depth below surface.  Visual assessment underground corroborates this statement.  Bolts and wire mesh were observed occasionally; however, no systematic bolting has been implemented underground.  In AMECs opinion, excavations where back span exceeds 3 m, and where the RMR value is less than 50, should be systematically bolted using a minimum 1.8 m (effective length) bolt.



Connection to the national power grid was deemed non-feasible during the Feasibility Study due to its inadequate and unreliable supply capacity.  Consequently, electrical power is provided by an on-site, diesel-fired power generating station.  The power generating plant consists of four generators, each capable of providing 1,600 kW of power (at 50Hz).  Under normal operations, three generators provide approximately 4,800 kW, thus allowing one generator on standby.



Production currently comes from the Frea (60%) and HVS (40%) veins at a rate of 750 t/d.  MSC is planning to increase daily throughput to 1,500 t/d.



An annual refining contract with Argor-Heraeus SA that is under negotiation will provide a market for gold and silver produced from the San José property.



Metallurgy and Processing

Several bench-scale metallurgical investigations have been conducted on Huevos Verde samples since testwork was initiated by Minera Andes in 1998.  Five metallurgical test programs were conducted on Huevos Verde samples between 1998 and 2005.  Frea was investigated as part of the 2005 Feasibility Study.  In these test programs, various metallurgical variables were examined to determine the optimum design parameters for the processing plant.  The Feasibility Study proposed a concentrator flowsheet using two-stage crushing, ball mill grinding, flash and rougher flotation, pre-aeration, concentrate cyanide leaching in conventional agitated tanks and dewatering, acid volatilization cyanide recovery (AVR), sulphur dioxide-air (SO2-Air) cyanide destruction, and Merrill Crowe-smelting for the production of a gold-silver doré.  A primary P80 grind of 75 μm was recommended, and an overall life-of-mine recovery of Au 90% and Ag 88% projected.



During early 2006, MSC and Gekko Systems (Gekko) jointly reassessed the Feasibility Study process flowsheet and began investigating the use of an alternative Gravity-Flotation-Intensive Leaching (GFIL) gold and silver recovery flowsheet that was developed by Gekko.  Gold and silver will be recovered by direct electrowinning and resin column scavenging from the concentrate leach solution.



During 2006 and early 2007 Gekko conducted two phases of bench scale metallurgical testwork on metallurgical samples from HV and Frea veins to support their process design. Additional amenability testwork was subsequently conducted by Tecsup in 2007 on metallurgical samples from the new Kospi vein. Overall AMEC considers the testing completed on this process to be at a pre-feasibility level. The testwork generally confirms the amenability of the HV, Frea and Kospi veins to either the original feasibility flotation-leaching or the Gekko GFIL flowsheets. In general the veins are metallurgically similar. Metallurgical variability test work should be completed on Kospi in the future for mine planning recovery purposes.



The 750 t/d Gekko based process plant currently being commissioned by MSC is the first application of the process on a continuous basis, in this configuration, at this scale and on this type of mineralogy.  MHC ́s prior experience with the Gekko ILR technology and the preliminary Gekko testwork results led them to decide to advance the San José project to construction based on the Gekko flowsheet without any need for further assessment or a detailed feasibility study on the process. The current flowsheet is based on a primary grind size of P80 110 μm.

The final product will be doré bars.  There is an option to produce a gold-silver concentrate, using a flotation cleaner and filter circuit provided, which will be bagged for shipping to a smelter.  This will only be activated if the intensive leach plant is not operating.



There is often some potential for unanticipated throughput and recovery loss and high operating cost risk exposure and learning curve typically associated with the commissioning a relatively new process concept or application that is progressed to construction in the absence of feasibility level definition.  Based on its review of the Gekko testwork and engineering, AMEC believes these risks exceed that of normal unanticipated start-up issues and there are some specific aspects of the flowsheet that may require additional capital cost, modification and time following start-up in order to achieve the design 750 t/day throughput and planned recoveries and operating costs.



AMEC has identified some potential issues with the Gekko test work which relate to the plant process design criteria, scale-up and implementation of the as-built Gekko process. These, as well the fact that the process is being put into production without completion of a detailed feasibility study, results in an increased risk that the recoveries indicated in the following laboratory batch scale testwork will not be achieved in the plant currently being commissioned.



AMEC ́s analysis of plant grind and throughput performance indicated the existing ball mill is too small to achieve the 750 t/d throughput and P80110 microns grind planned. At the planned grind AMEC expect the mill throughput will on average be about 88% of planned throughput.



AMEC also believes that the planned P80110 microns product size does not provide an optimum recovery and recommends 74 microns is considered. This appears to be supported by commissioning plant data AMEC reviewed. Overall AMEC believes additional grind capacity will be required to achieve the throughput and recoveries planned.



AMEC believes a gravity Falcon and flotation flowsheet is capable of achieving similar recoveries to the more complex Gekko Jig-Falcon gravity system and flotation flowsheet. AMEC recommends the recovery benefits of utilizing the Gekko Jig plant are reviewed in future plant trials relative to the ongoing operating and maintenance costs of operating this equipment.



Based on laboratory leach results Gekko concluded the San José GF concentrates are amenable to intensive cyanidation, using the Gekko In-Line Leach reactor.  However no actual test or pilot work was conducted in an In-Line leach reactor and AMEC believes there is additional recovery risk associated with implementing continuous in-line leaching based on batch leach test work results.



Gekko reported concentrate cyanidation test work gave average gold and silver leach extractions of about 95-97%, in 24 to 48h.  AMEC notes the reporting time of 24 -48 h, is longer than a 9 h residence time planned in the actual Gekko process. Silver-sulphide dominant mineralization similar to the flotation concentrate typically requires extended leach times (48h) to achieve efficient silver extractions.  Consequently the indicated test work leach extractions should be treated with caution as AMEC believes actual Gekko plant leach recoveries will be lower than this. AMEC believes additional leach capacity will be required and this is supported by current commissioning performance.



AMEC believes the use of lower gravity-flotation concentration ratios (higher concentrate weight recoveries) than planned will improve recovery performance. High concentration ratios are currently being implemented to offset Gekko reactor throughput-residence time limitations that result in low gold and silver leach recoveries.  However additional leach capacity will be required to do this.



AMEC has not assessed or costed the above risks in detail but have included an additional sustaining capital provision of $5 million in the project cash flow over Years 1 and 2 to cover potential unanticipated and unspecified modifications to the milling and concentrate leaching and recovery circuits that could be required to achieve the throughput and recoveries ultimately expected.



36



---

AMEC has also used a reduced recovery of 75% Au and 65% Ag in the initial year of operation based on current plant performance described in 16.5.3. AMEC expects that once required modifications are made to the process plant the planned throughput and recovery indicated by the feasibility study of about Au 90% and Ag 88% will ultimately be achieved.



Plant commissioning was initiated in July 2007, but the ramp-up is taking longer than initially planned because of commissioning and operational issues problems associated with the implementation of the Gekko process, which are still being resolved. During AMEC ́s visit the plant was still being commissioned and operating at a lower throughput and recovery than planned. Plant throughput and recovery continued to improve from August to September under Gekko ́s supervision, but AMEC expects modifications will ultimately be required to the process plant to achieve the planned throughput and recovery.



Most process control was being done manually due to unstable plant operation. The control philosophy should be reviewed.



Plant accountability based on physical production declined from 88% in August to 80% in September. AMEC regard this as low and should be investigated.  During AMEC ́s site visit some poor sample preparation practices associated with the mill feed head sample were noted which could be expected to introduce some sampling assay bias and should be corrected. A possible source of the current plant negative variance also includes overstating mill feed and physical theft and AMEC recommend the plant mill feed weigh to meter calibration should be checked and security controls reviewed.



Cost Estimates and Financial Analysis

The total estimated capital cost to design and build the facilities planned in the 2005 Feasibility Study amounted to US$61.3 million (AMEC, 2005).  A recent capital cost update provided by MSC shows an increase of 48%, to US$90.6 million (excluding sustaining capital costs, which vary from US$12 million to US$7 million per year until 2010).  The estimate covers the direct field costs of executing the project, plus the indirect costs associated with design, procurement and construction efforts, including contingency and working capital.



MSC is considering re-evaluating the concept of installing a power line in order to reduce operating costs; this has not been included in the financial analysis.



The operating costs include those costs required to produce at a rate of 750 t/d, including all mine development costs (e.g. ramps, ventilation raises, backfill raises, etc.).  These costs have been prepared using US dollars and exclude: contingencies, allowances for escalation, value-added taxes and import duties, and commercial fees and expenditures.  The average cash operating costs are estimated at US$94/t of ore processed, or U$235/oz AuEq.



Smelter terms are consistent with industry standards and are considered in the cash flow calculations.



Long-term metal prices selected for the analysis were US$575 for gold and US$9 for silver.



The project was evaluated on a stand alone, 100% equity-financed basis using a discounted cash flow analysis.  Cash inflows consist of annual revenue projections for the remaining mine-life.  Cash outflows such as sustaining capital, operating costs and taxes are subtracted from the inflows to arrive at the annual cash flow projections.   Annual net cash flow (NCF) projections are then discounted for time and risk and summed to arrive at a net present value (NPV).



The results of the economic analysis represent forward-looking information as defined under Canadian and US securities law. The results depend on inputs that are subject to a number of known and unknown risks, uncertainties and other factors that may cause actual results to differ materially from those presented here. Some of the key technical risks include: lower than anticipated metallurgical recoveries of gold and silver from the Gekko system; lower than expected mine recovery and higher than expected dilution; increases to future operating and capital costs; the fact that mineral resources and mineral reserves are estimates based on limited sampling data, interpretation of geology and assumptions applied that may change with increased exploration, development and mining; and future metal prices may change from those used in the economic model.

The NPV results for various discount rates are presented in Table 1-4.



Table 1-4: San José NPV (Base Case 8%)

|--------------------------------- | ----- | -------
|After Tax                         | Units | 000   
|Cumulative Undiscounted Cash Flow | (US$) | 149,535
|NPV  5 %                          | (US$) | 109,315
|NPV  8 %                          | (US$) | 91,279 
|NPV  10 %                         | (US$) | 81,166 
|NPV  15 %                         | (US$) | 61,026 



The sensitivity analysis was performed on the Base Case NPV using an 8% discount rate.  Positive and negative variations, up to 30% in either direction, were applied independently to the gold and silver prices, and the capital and operating costs.



The results of this analysis demonstrate that the projects financial outcome is most sensitive to variation in gold price and silver price.  The next most sensitive parameter is the operating costs.  The capital cost is the parameter studies which had the least impact on the sensitivity of the NPV.



The cash-flow model was created on a moving forward basis.  This implies that all of the capital already spent is considering sunk and was not included in the required initial investment.  Therefore, the payback period for the remaining initial investment is 2.5 years. It is important to note that the sunk costs on this project are substantial.



Conclusions and Recommendations



Approximately ten years after the San José Property was first acquired by Minera Andes and through several successful exploration programs and development phases, mine pre-production was initiated at the Huevos Verdes and Frea Veins on 26 June 2007.



In some areas, the existing Mineral Resources and/or Reserves remain open along strike, or at depth.  Additional drilling is recommended to further delineate these zones and ultimately to add to existing Mineral Resource and Mineral Reserves.  Prior to the next run of the resource model several database and modeling issues should be addressed to improve the accuracy of the estimate.  Most of these issues were uncovered during AMEC ́s involvement with the audit and the review of the geological model and supporting database.



AMEC has noted that some mineralized intervals, showing vertical and horizontal continuity parallel to the main vein and logged in the drill holes, were not interpreted and captured in the current resource model.



Some of these improvements include the twinning of a representative number of RC and pre-2004 core holes, an evaluation of decay of cyclicity for the RC holes, further review of collar and downhole surveying for the drill holes, more detailed geological interpretations and further review on controls of mineralization, the construction of an oxide domain in the resource model, and continued review and improvement of the underground sampling methodology.



For the Huevos Verdes, Frea and Kospi veins, AMECs view is that the sample spacings currently being used for the Indicated category are the maximum allowable.  This relates to the ability to determine the tonnage of mineable ore and adequately delineate the boundaries of the ore shapes (i.e. modelling the geometry of the veins).  Subsequent to additional drilling and/ore underground development MSC should consider re-running the variography and constructing a new resource model to see if the resource classification can be improved.



The Gekko recovery process will need to be closely monitored to determine if the desired gold and silver recoveries are being achieved.  Plant modifications are recommended by AMEC to achieve the life of mine recoveries projected at the required throughput. These include reducing the grind size to a primary P80 grind of 75 microns (from the 110 microns currently in the Gekko design criteria).  The additional capital costs to achieve this have not been reviewed in detail, but are roughly estimated at US$5.0M.



38



---

In addition to the above plant-related capital costs, there are approximately US$20.8M from the 2007 revised capital cost estimate (MSC) that are still to be spent plus approximately US$37.2M in sustaining capital from 2007 until the end of mine life.



MSCs next mineral reserve estimates will require improved documentation to assist in a transparent conversion of mineral resources to mineral reserves.  AMEC strongly recommend that MSC identify sill pillar areas in the stoping blocks and assign appropriate dilution and mining recovery factors to those areas.  AMEC agrees with the reduced dilution factor used by MSC (15% in the Feasibility Study versus 12% in the current LOM) based on visual observations at HVS and Frea; however, operational experience will need to be gained to substantiate a higher mining recovery factor.



AMEC anticipates adverse ground conditions during sill pillar recovery.  Consequently, it is recommended to evaluate alternative mining methods to optimize sill pillar recovery.



Numerous other high priority targets have been identified on the Property through early previous stage drilling and surface exploration programs.  The main targets are Odin (A and B), Ayelen, Flor, HV West, Kospi 1, Kospi South, Lourdes, Frigga, Aguas Vivas, Roadside, and Portuguese West.  Although these are all considered to be at early stages of exploration, MSC believes that significant upside potential for the Property occurs within these prospects.  Future explorations efforts should be focused within these zones.



The San José Property should be further evaluated for additional vein style gold and silver mineralization.  An exploration program, as outlined below, is recommended.  The total cost for the next phase of exploration is approximately US$3.92M and includes 145 drill holes totalling 38,300 m (at the time of this report the program has already commenced and 24 holes totalling 5,858 m had been completed from the overall program).



Exploration Subsequent to San José Technical Report

The technical information in this section have been prepared by or under the supervision of Brian Gavin, Vice President  Exploration of the Corporation and a qualified person within the meaning of NI 43-101.  Mr. Gavin verified the data disclosed, including sampling, analytical and test data underlying the results set out above.  Splits from the drill core samples were submitted to Alex Stewart Assayers, Argentina, S.A., in Mendoza, Argentina, for fire assay and ICP analysis. The accuracy of results was tested through the systematic inclusion of standards, blanks and check assays.



Drilling in the fourth quarter of 2007 defined 2.8 km of strike length along the Odin and Ayelén veins. The highest grade intercept from this drilling campaign was in hole SJD-412 that encountered 52.44 g/t (1.69 ounces per ton opt) gold and 1,147 g/t (37 opt) silver over 1.68 meters.



During 2007, approximately 28,587 meters of core drilling totaling 113 drill holes was conducted on several targets identified at the San José Project. In September thru December of 2007, 82 holes totaling 20,274 meters were drilled at the Frea, Odin, Ayelén, Frigga, and Lourdes targets. Assay results for 19 drill holes are still pending. Three of the areas (Frea, Odin, and Ayelén) contained high-grade gold/silver mineralization discovered in late 2005 through reconnaissance drilling of blind geophysical targets.



The majority of the fourth quarter 2007 drilling concentrated on the Odin and Ayelén veins covering approximately 2.8 kilometers of strike length along these open-ended mineralized veins. The drilling completed in 2007 extended the known mineralization along the Odin and Ayelén vein trends another 1000 meters along strike, more than a 64% increase in strike length from the 2005 discovery drilling.



The drilling completed in 2007 also extended the known mineralization along the Frea vein trend another 500 meters along strike, an increase of 87% in strike length. Frea vein mineralization now extends for 700 meters of strike and it remains open to further expansion to the northwest and to depth.

The 2007 drilling concentrated on infill and drilling the northwest extension of the Frea vein. Significant drilling results include SJD-364 which encountered 11.57 g/t (0.37 opt) gold and 1,291 g/t (42 opt) silver over 3.64 meters of high grade mineralization, drill hole SJD-386 which encountered 1.50 meters grading 12.87 g/t (0.41 opt) gold and 710 g/t (23 opt) silver and drill hole SJD-391 encountered 1.47 meters containing 9.41 g/t (0.30 opt) gold and 758 g/t (24 opt) silver. In 2007, the drilling at the Frea vein indicated that it is an open-ended mineralized silver/gold vein.



Four holes were drilled in the Lourdes target plus five holes were drilled in the Frigga target and one hole was drilled at the Kospi vein. These holes encountered quartz veining and/or hydrothermal breccia that did not return values above background levels of gold and silver. Although only background gold and silver values were encountered, the geologic features identified at these targets are consistent with precious metal-bearing epithermal systems.



During 2008 approximately 19,358 metres of core drilling totaling 81 drill holes had been completed at the San José Project.  The drilling was focused primarily on the Frea, Odin and Ayelén veins.  Infill and step-out drilling on these veins continues to indicate significant potential to further increase the current reserve/resources on the property.  Highlights of the program included:



·

Frea Vein:  Drill hold SJD-477 which intersected three high-grade splays of the main Frea vein of 0.30 meters grading 25.23g/t (0.81 opt) gold 4,945 g/t (159 opt) silver and 0.93 m grading 14.82 g/t (0.48 opt) gold and 1,688 g/t (54 opt) silver and 1.30 meters of 13.30 g/t (0.43 opt) gold and 1.532 g/t (49 opt) silver.

·

Odin Vein:  A total of 37 holes were drilled on the Odin vein (bringing the total to 88 holes) covering approximately 1600 meters along the strike of the vein, to a depth of approximately 200 meters.  Hole SJD-483 intercepted 2.12 meters of 6.91 g/t (0.20 opt) gold and 486 g/t (14.2 opt) silver.  The Odin vein remains open to the west along strike and to depth.

·

Ayelén Vein:  Additional mineralization was identified along 1.2 kilometers of strike and 200 meters of depth.   However, the 2008 drilling encountered predominantly moderate to low grade mineralization.



Management believes that the new silver/gold mineralization discovered in the Odin, Ayelén and Frea veins represents additional mineralization that could potentially add to the current Mineral Reserves and Mineral Resources at the San José Project.



LOS AZULES PROJECT

Unless otherwise stated, the information in this section is based on the Los Azules Technical Report.   In accordance with instruction (ii) of Item 5.4 of 51-102F2, a form prescribed by NI 51-102, the summary contained in the Los Azules Technical Report is reproduced below:



The project consists of a porphyry copper deposit occurring on land owned by MAI to the south (approximately 3400 ha) and adjacent property owned by MIM, an affiliate of Xstrata to the north. In November of 2007 MAI and MASA signed a definitive Option Agreement with MIM and Xstrata. MAI, in its fourth drilling program, is currently drilling on both MAI-controlled land and Xstrata land to further define the limits and complete in-fill of the mineralized zones.



Previous work recognizes two principal geological groups at Los Azules: an upper volcanic suite and a lower intrusive complex. This porphyry copper deposit seems to represent a typical porphyry system that consists of a supergene-enriched zone superimposed on a primary mineralized zone. The leached cap zone above the supergene enrichment zone appears to be devoid of copper mineralization, as none has been noted from surface or drill core observations.



Mineralization at the Los Azules deposit consists of various copper sulfide minerals in two main zones consisting of the supergene and primary zones. Minerals in the supergene enrichment zone are comprised of chalcocite, chalcopyrite, and pyrite. The supergene zone varies considerably in thickness from 40 m to well over 200 m, as some holes bottomed in copper mineralization. Mineralization in the primary zone consists of chalcopyrite and pyrite with minor amounts of bornite and covellite. Mineralization controls consist of the extensive stockworks, veining and faulting as noted in the drill core.  At the current drill hole spacing (400 m north-south by 200 m east-west) the copper porphyry system appears to be continuous from drill hole to drill hole. Locally the mineralized porphyry target appears to extend about 3 km north-south by 1 km east-west.

A three-dimensional block model was developed to estimate copper grade. The Los Azules mineral resources are summarized in Table 1-1 at a series of copper cutoff grades for comparison purposes. In order to comply with CIM definitions regarding selection of a base case, a base case was selected at a cutoff grade of 0.35% copper, which is consistent with other operations exhibiting similar characteristics, potential scale of operation and location.

Note: Mineral Resources do not have demonstrated economic viability.



At the present time, the Los Azules copper deposit is considered to be an exploration-stage project. There are currently no mineral resources or mineral reserves based on Canadian National Instrument 43-101 standards.



OTHER PROPERTIES

In addition to the San José Project and the Los Azules Project, we own a 100% interest in several exploration properties located in the Santa Cruz Province, Argentina.  We hold our interest in these properties pursuant to 15 cateos and 29 manifestations of discovery covering an aggregate of 89,775 hectares (221,839 acres).



Management believes that the exploration results received to date indicate that certain of these properties have numerous similarities to the San José Project.

As of the date hereof, the number of common shares of the Corporation beneficially owned, or controlled or directed, directly or indirectly, by all directors and executive officers of the Corporation as a group is 46,709,343 or 24.56% of the issued and outstanding common shares of the Corporation.



The term of office of the directors expires annually at the time of the Corporations annual general meeting or until their successors are elected or appointed.



Cease Trade Orders, Bankruptcies, Penalties, or Sanctions

Except as disclosed below, no director or executive officer of the Corporation is, as at the date hereof or has been within the ten years prior to the date hereof, a director, chief executive officer or chief financial officer of any company that was the subject of a cease trade or similar order or an order that denied the relevant company access to any exemption under securities legislation, for a period of more than 30 consecutive days issued: (1) while that person was acting as director, chief executive officer or chief financial officer (2) after the director or executive officer ceased to be a director, chief executive officer or chief financial officer and which resulted from an event that occurred while that person was acting in that capacity.



Mr. Ambrose has advised the Corporation that he is a director of Century Mining Corporation (Century). On March 20, 2008, the British Columbia Securities Commission issued a cease trade order against the insiders of Century for not filing, in the correct form, a technical report under NI 43-101, interim financial statements for the financial period ended September 30, 2007 pursuant to NI 51-102, and management discussion and analysis for the period ended September 30, 2007.   The cease order was rescinded on July 18, 2008 and is no longer in effect.



No director or executive officer of the Corporation or shareholder holding a sufficient number of securities of the Corporation to affect materially the control of the Corporation is, as at the date hereof or has been within the ten years prior to the date hereof, a director or executive officer of any company that, while that person was acting in that capacity, or within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee to hold its assets.



44



---

No director or executive officer of the Corporation or shareholder holding a sufficient number of securities of the Corporation to affect materially the control of the Corporation, has been subject to any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with a securities regulatory authority, or has had any other penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor in making an investment decision.



Personal Bankruptcies



No director or executive officer of the Corporation or shareholder holding a sufficient number of securities of the Corporation to affect materially the control of the Corporation, has during the ten years prior to the date hereof become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or become subject to or instituted any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold such persons assets.



Conflicts of Interest



The directors and officers of the Corporation are, or may become, directors or officers of other companies with businesses which may conflict with the business of the Corporation. Directors are required to act honestly and in good faith with a view to the best interests of the Corporation. In addition, directors in a conflict of interest position are required to disclose certain conflicts to the Corporation and to abstain from voting in connection with the matter. To the best of the Corporations knowledge, there are no known existing or potential conflicts of interest between the Corporation or a subsidiary of the Corporation and a director or officer of the Corporation or a subsidiary of the Corporation as a result of their outside business interests at the date hereof. However, certain of the directors and officers serve as directors and/or officers of other companies. Accordingly, conflicts of interest may arise which could influence these persons in evaluating possible acquisitions or in generally acting on behalf of the Corporation.



LEGAL PROCEEDINGS AND REGULATORY ACTIONS

There are no material legal proceedings involving the Corporation or a subsidiary of the Corporation or of which their respective properties are the subject matter of as at the date of this AIF and the Corporation knows of no such proceedings currently contemplated.



There have been no penalties or sanctions imposed against the Corporation by a court relating to securities legislation or by a securities regulatory authority, or imposed by a court or regulatory body against the Corporation that would likely be considered important to a reasonable investor in making an investment decision, and the Corporation has not entered into any settlement agreements with a court relating to securities legislation or with a securities regulatory authority.



INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS

No director or executive officer of the Corporation, no person or company that beneficially owns, or controls or directs, directly or indirectly, more than 10% of any class or series of the Corporations outstanding voting securities and no associate or affiliate of any of such persons or companies has any material interest, direct or indirect, in any transaction within the three most recently completed financial years or during the current financial year that has materially affected or will materially affect the Corporation other than as disclosed below.



On December 20, 2005, the Corporation entered into a private placement agreement (the First McEwen Agreement) at arms length with Robert R. McEwen of Toronto, Ontario, providing for the purchase by Mr. McEwen or any associate or affiliate of Mr. McEwen (together, McEwen) of an aggregate of 15,414,740  units of the Corporation (First Private Placement Units), at a price of C$0.35 per First Private Placement Unit, for gross proceeds of C$5,395,159 (the First Private Placement). Each First Private Placement Unit was comprised of one common share and one-half of one common share purchase warrant (the First Private Placement Warrant). One whole First Private Placement Warrant entitled the holder thereof to purchase one additional common share at an exercise price of C$0.55 per common share.

---

In addition, on December 20, 2005 the Corporation signed a further subscription agreement, (as amended, the Second McEwen Agreement), with McEwen, granting McEwen the right to acquire a further 13,156,689 units of the Corporation, on the same terms as the First Private Placement, for gross proceeds of C$4,604,841.10 (the Second Private Placement). The Second Private Placement closed on March 8, 2006.



In connection with the aforementioned private placements McEwen was granted the right, from time to time and at any time, to nominate one individual (the Subscriber Nominee) to the board of directors of the Corporation for a period of five years following closing of the Second Private Placement provided McEwen then owns not less than 10% of the issued and outstanding common shares of the Corporation.  In addition, the Corporation agreed to use all reasonable efforts to cause its board of directors to pass such resolutions and to take such other actions as may be required in order to maintain the number of members of the board of directors of the Corporation at not more than six.



Pursuant to an agreement dated May 5, 2006 Mr. McEwen completed the early exercise of 14,285,714 warrants then held by him.  In consideration for the early exercise of these warrants, the Corporation issued to Mr. McEwen 2,000,000 new common share purchase warrants. Each new warrant entitles McEwen to purchase one common share at an exercise price of C$1.80 per share. On May 4, 2007 Mr. McEwen exercised these 2,000,000 common share purchase warrants.



As of the date of the AIF, Mr. McEwen holds 46,057,143 or 24.33% of the issued and outstanding common shares of the Corporation and 100,000 options each exercisable for one common share at a price of C$0.81 per share.



TRANSFER AGENT AND REGISTRAR

The registrar and transfer agent for the Corporations common shares is Computershare Trust Company of Canada, 600, 530-8th Avenue SW Calgary, Alberta, T2P 3S8. Registration and transfers of the Corporations common shares may be effected through Computershares offices in Toronto, Ontario and Vancouver, British Columbia.
