Item 2. Management’s Discussion and Analysis or Plan of Operations

The following discussion of the operating results and financial position of Golden Queen Mining Co. Ltd. (the “Company”) is as at May 13, 2011 and should be read in conjunction with the consolidated financial statements of the Company for the quarter ended March 31, 2011 and the notes thereto.

The information in this Management Discussion and Analysis is prepared in accordance with U.S. generally accepted accounting principles and all amounts herein are in U.S.$ unless otherwise noted.

The Soledad Mountain Project

The Company presented the results of the updated feasibility study and economic analysis for its Soledad Mountain Project in a news release on April 6, 2011. The updated feasibility study and economic analysis was prepared by Norwest Corporation with input from independent consulting engineers and management.

High Points

• A projected, all-inclusive, average cash cost per ounce of gold produced net of silver credits of $133/oz. Silver credits are based on $39.63/oz of silver.
• Major approvals and permits have been secured.
• Estimated development costs, net of lease financing of the mining equipment but including working capital, are $88.9million.
• The Project is serviced by existing infrastructure, accessible by state highway, and proximate to a local experienced workforce and housing.
• A relatively low waste to ore mining ratio of 1.85:1.

Cash Flow Analyses

The cash flow analyses in the updated feasibility study were done on a constant dollar, pre-tax, all-equity basis. The study provides the following economic estimates for the Project:

The Project has an indicated internal rate of return (“IRR”) on capital employed of 83.7% . The net present value (“NPV”) is $722million with a discount rate of 8.0% and the undiscounted, cumulative net cash flow is approximately $1.16billion. The indicated contribution of gold and silver to gross revenues is 77% and 23% respectively at current gold and silver prices with an all-inclusive, average cash cost per ounce of gold produced, net of silver credits, of $133/oz. Gold and silver prices used to model the cash flows were $1,457.00 and $39.63 respectively, the London a.m. fix for precious metals on April 6, 2011.

If gold and silver prices are reduced by 10% from current levels, the indicated IRR is 74.1%, the NPV is $579million with a discount rate of 8% and the undiscounted, cumulative net cash flow is $996million. The all-inclusive, average cash cost per ounce of gold produced, net of silver credits, increases from $133/oz to $157/oz at these lower gold and silver prices.

When trailing 36-month average gold and silver prices of $1061.25/oz and $17.78/oz respectively to the end of March 2011 are used to model the cash flows, the indicated IRR is 51.6% before taxes, the NPV is $343million with a discount rate of 8% and the undiscounted, cumulative net cash flow is $617million. The all-inclusive, average cash cost per ounce of gold produced, net of silver credits, increases further to $313/oz. The trailing 36-month average precious metals prices are accepted by the U.S. Securities And Exchange Commission when reporting mineral reserves.

Overview

The Company plans to develop a gold-silver, open pit, heap leach operation on its Soledad Mountain property, located just outside the town of Mojave in Kern County in southern California. The Project will use conventional open pit mining methods and the cyanide heap leach and Merrill-Crowe processes to recover gold and silver from crushed, agglomerated ore. The planned, average ore and waste mining rates are 4.9million tons and 9.1million tons per year with a waste to ore mining ratio of 1.85:1 for a combined mining rate of ore and waste of 14million tons per year. Gold and silver production are projected to average 75,000oz and 950,000oz respectively per year although this is expected to fluctuate considerably from year to year depending upon the ore head grades. Gold and silver production is projected to be 936,332oz of gold and 10,426,654oz of silver over a period of approximately 13 years.

The Company is proceeding with or has completed detailed engineering designs for each of the key facilities to be constructed.

Infill Drill Program

The Company initiated an infill drill program in April of 2011, which was completed in early May of 2011. Samples of mineralization recovered from the drilling have been submitted for analysis, with results expected by the end of May 2011.

The drill program was designed to test targets within the areas of the planned North-West and East open pits. A total of 9 holes were drilled within the North-West open pit area with a total length of 2,020 feet. The North-West open pit is the planned location of the first phase of mining. A total of 11 holes were drilled within the East open pit area with a total length of 4,268 feet.

The objective of the drill program is to upgrade inferred resources to a level of assurance which would allow for re-classification as reserves. In addition, the drilling will confirm the design and location of access roads and test continuity of mineralization, which typically has been excellent in most areas previously tested. The impact is expected to be a further lowering of mining ratios.

Aggregate

It is expected that a byproduct aggregate and construction materials business can be developed once the heap leach operation is in full production, based on the location of the Project in southern California with close proximity to major highways and railway lines. The source of raw materials will be suitable quality waste rock specifically stockpiled for this purpose. The waste rock can be classified into a range of products such as riprap, crushed stone and sand with little further processing. Test work done in the 1990s confirmed the suitability of waste rock as aggregate and construction material. The Company also plans to process and sell leached and rinsed residues from the heap leach operation for a range of uses to local and regional markets. It is intended that these products will be sold over an extended mine life of 30 years, but no contributions from the sale of such products will be included in the cash flow projections until long term contracts for the sales of these products are secured.

Permitting Update

A detailed review of approvals and permits required for the Project is provided in the Company’s latest Form 10-K filing with the SEC. The following is therefore only a brief update.

Land Use - Conditional Use Permits

The Kern County Planning Commission unanimously approved the Project at its regularly scheduled meeting in Bakersfield on April 8, 2010. All appeals that were subsequently filed against the Commission’s decision have been withdrawn and the decision made by the Planning Commission is now

final. The Planning Commission approved minor wording changes to the Conditions of Approval on October 28, 2010.

The State of California introduced backfilling requirements for certain types of open pit metal mines in December 2002. Norwest Corporation prepared a life-of-mine waste rock management plan and this plan incorporates sequential backfilling of mined-out phases of the open pit with limited double-handling of waste rock at the end of the mine life. This plan has been incorporated in the Planning Commission approvals. The Company is currently preparing a submission to be made to the Kern County Planning Department demonstrating ultimate disposition of leached and rinsed residues from the heap leach operation consistent with performance standards in applicable regulations.

The Bureau of Land Management confirmed that its Record of Decision approving the Plan of Operations under NEPA in November 1997 remains valid.

Water Quality – Waste Discharge Requirements

The Lahontan Regional Water Quality Control Board (the “Board”) unanimously approved Waste Discharge Requirements and a Monitoring and Reporting Program for the Project at a public hearing held in South Lake Tahoe on July 14, 2010. The Board order was subsequently signed by the Executive Officer of the Board and is now in effect.

Air Quality – Authority to Construct and Permit to Operate

The Air Quality and Health Risk Assessments for the Project were completed and submitted to the Planning Department and the Eastern Kern Air Pollution Control District (“EKAPCD”) on July 21, 2009. This report was approved by Kern County Planning Commission on April 8, 2010, as part of the certification of the Supplemental Environmental Impact Report.

Ten applications for Authority to Construct permits were submitted to the EKAPCD in February 2011. It is expected that EKAPCD will issue Authority To Construct permits in June 2011.

The Authority to Construct approvals will be converted to a Permit to Operate after construction has been completed and subject to inspection by EKAPCD.

Results of Operations

Following are the results of operations for the three month period ended March 31, 2011, and the corresponding period ended March 31, 2010.

The Company had no revenue from operations.

During the quarter, the Company incurred general and administrative expenses of $484,910 (2010 - $567,712). Costs were lower for the quarter when compared with the same period in 2010, due to the following non-recurring costs incurred in 2010:

• Legal fees were incurred in support of ongoing efforts to secure permits for the Project, and
• Consulting engineering fees were higher due to the significant amount of detailed engineering completed for Project facilities. The detailed engineering allowed contractors to provide cost estimates for construction of the facilities.

The following significant costs were incurred in general and administrative expenses during the period ended March 31, 2011:

• $146,319 (2010 - $29,896) for detailed engineering of the Phase 1, Stage 1 heap leach pad and the associated site drainage plans and ongoing permitting support. Costs were higher by $116,423 in

2011 as work on the detailed design of the Phase 1 heap leach pad was accelerated and completed.


• $60,610 (2010 - $91,878) for ongoing permitting support, for overseeing the quarterly groundwater sampling and analysis program and preparing the quarterly report for the Lahontan Regional Water Quality Control Board. Costs were higher by $31,268 in 2010 as studies were done on the occurrence of arsenic in groundwater, the use of cyanide in heap leaching and the occurrence of mercury and capture of mercury.
  
• $40,509 (2010 - $17,873) for preparing Authority to Construct permit applications and ongoing monitoring, maintenance and data recovery from the meteorological station on site.
  
• $52,770 (2010 - $163,285) for legal fees incurred in support of ongoing efforts to secure permits for the Project and in negotiations with landholders. Legal fees were higher by $110,515 in 2010 due to work done in preparing for the public hearings held in April 2010.
  
• $371,000 (2010 - $0) for the purchase of four properties and a down payment on a fifth property (fee land).
  
• $74,317 for work on the updated feasibility study, ongoing mine design and drafting support (2009 –$33,258). Costs increased by $41,059 in 2011 primarily due to work on the updated feasibility study for the Project.
  
• $136,560 for accounting and audit fees (2010 – $68,271).

Interest income of $12,574 (2010 - $640) was higher by $11,934 as there was more cash on deposit. Interest rates remained low during the quarter. There was no interest expense during the quarter.

The Company incurred a net loss of $720,868 (or $0.01 per share) during the quarter as compared to a net loss of $326,305 (or $0.00 per share) during the first quarter of 2010.

Summary of Quarterly Results

Results for the eight most recent quarters are set out in the table below.

The results of operations can vary from quarter to quarter depending upon the nature, timing and cost of activities undertaken during the quarter and whether or not the Company incurs gains or losses on foreign exchange grants stock options or makes adjustments on quarterly or annual financial statements.

Reclamation Financial Assurance and Asset Retirement Obligation

The Company provided reclamation financial assurance in the form of an Irrevocable Payment Bond Certificate with Union Bank of California in the amount of $286,653 on October 21, 2009 for 2010. The financial assurance is reassessed annually and the estimate for reclamation of historical disturbances on the property is $283,809 for 2011.

The asset retirement obligation accrual is estimated at $197,900 and this is shown as a liability on the consolidated balance sheet. The actual obligation could differ materially from these estimates.

Advance Minimum Royalties

Advance minimum royalties of $11,826.71 were paid to landholders in the first quarter of 2011.

A mining lease agreement with one group of landholders expired in 2004. The group of landholders accepted an extension agreement in March 2011 and this agreement has been sent to the landholders for their signatures.

Mining lease agreements with groups of landholders expired in June and July of 2010 and discussions are under way with these groups of landholders for an extension of the agreements.

Off-balance Sheet Arrangements

The Company has no off-balance sheet arrangements.

Stock Option Plan

The Company’s current stock option plan (the “Plan”) was adopted by management of the Company in 2008 and approved by shareholders of the Company in 2009. The Plan provides a fixed number of 7,200,000 common shares of the Company that may be issued pursuant to the grant of stock options. The exercise price of stock options granted under the Plan shall be determined by the Company’s Board of Directors, but shall not be less than the volume weighted average trading price of the Company’s shares on the Toronto Stock Exchange for the five trading days immediately prior to the date of the grant. The expiry date of a stock option shall be the date so fixed by the Board subject to a maximum term of five years. The Plan provides that stock options will terminate on the earlier of the expiry of the term and (i) 12 months from the date an option holder dies, (ii) 90 days from the date from the date the option holder ceases to act as a director or officer of the Company, or (iii) 60 days from the date the option holder ceases to be employed, or engaged as a consultant, by the Company.

The Company granted 1,950,000 stock options to directors, officers and consultants of the Company pursuant to the Plan on January 28, 2009. The options are exercisable at a price of C$0.26 per share for a period of 5 years from the date of grant. The Company also granted 50,000 stock options to a consultant of the Company pursuant to the Plan on April 19, 2010. The options are exercisable at a price of C$1.24 per share for a period of 5 years from the date of grant.

Transactions with Related Parties

Mr. H. L. Klingmann was paid $36,100 (2010 - $34,500) for services as President of the Company and Mr. Chester Shynkaryk was paid $4,600 (2010 - $4,300) for consulting services to the Company for the three months ended March 31, 2011.

There were no other related party transactions during the quarter ended March 31, 2011.

The Company amended a consulting services agreement originally entered into in 2004 with Mr. H. Lutz Klingmann, the President of the Company, in May of 2010. Under the original agreement, upon receipt by the Company of a bankable feasibility study and the decision to place the Property into commercial production, a bonus of 150,000 common shares would be issued and upon commencement of commercial production on the Property, a bonus of 150,000 common shares would be issued. Pursuant to the amended agreement, an alternative 300,000 bonus shares would be issuable upon a change of control transaction or upon a sale of all or substantially all of the Company’s assets, having a value at or above C$1.00 per share of the Company, with a further 300,000 bonus shares being issuable in the event the change of control transaction or asset sale occurred at a value at or above C$1.50 per share. As at March 31, 2011, the milestones had not been reached and no accrual was made in connection with these arrangements.

Fair Value of Financial Instruments

The carrying amount reported in the balance sheets for cash and cash equivalents, receivables, accounts payable and accrued liabilities approximates fair value because of the immediate or short-term maturity of these financial instruments. The company does not hold any bank or non-bank asset-backed commercial paper. The fair value of the reclamation financial assurance approximates carrying value because the stated interest rate reflects recent market conditions. It is the opinion of management that the Company is not exposed to significant interest, currency or credit risk arising from the use of these financial instruments.

Private Placement

The Company completed a non-brokered private placement with Gammon Gold Inc. on June 1, 2010, whereby Gammon Gold purchased 5,000,000 units of the Company at a price of C$1.60 per unit for total proceeds of $7,634,316 (C$8,000,000). Each unit consists of one common share, one quarter of one Class A Warrant, and one quarter of one Class B Warrant. Each Class A Warrant entitles Gammon Gold to purchase a common share at a price of C$1.75 for a period of 18 months from the closing date. Each Class B Warrant entitles Gammon Gold to purchase one common share at a price of C$2.00 for a period of 18 months from the closing date. The aggregate fair value of the Class A and B purchase warrants was $1,726,518 and the amount has been recorded as derivative liability and the Company allocated the remaining proceeds of $5,907,798 to the common shares.

Subject to certain conditions, Gammon Gold Inc. was granted the right to participate in future financings to maintain its equity position in the Company.

Liquidity and Capital Resources

The Company held $6,103,689 in cash and cash equivalents on March 31, 2011.

Cash used in Operating Activities:

Cash was used mainly for the ongoing development of the Project with major expenditures in three areas:

• Consulting engineering fees remained high due to the significant amount of detailed engineering completed for Project facilities;
• Legal fees were incurred in support of ongoing efforts to secure permits for the Project and in negotiations with landholders and
• Property taxes (50%) were due and paid during the quarter.

Cash from Financing Activities:

Cash was received from financing activities during the three months ended March 31, 2011 as follows:

• A director exercised a total of 150,000 options on shares for proceeds of C$115,500 (US$ 116,816) during the quarter.

Cash used in Investing Activities:

The Company purchased four properties and made a down payment on a fifth property (fee land) for approximately $371,000 during the quarter. Further increases in our land position are required to provide room for the construction of facilities for the aggregate production component of the Project after the start of the open pit heap leach operation.

Working Capital

As at March 31, 2011, the Company held $6,103,689 in cash and cash equivalents, had no long-term debt, and had current liabilities of $252,570.

Management does not expect that additional cash will be required beyond cash currently on hand for ongoing work on permits for the Project, for paying advance minimum royalties, for additional property purchases, for detailed engineering of facilities for the Project, for ongoing work on site, and for general corporate purposes to the end of 2011. Refer also to Outlook below.

Outstanding Share Data

The number of shares issued and outstanding and the fully diluted share position are set out in the table below.

Outlook

If all approvals and permits are secured for the Project and a production decision is made, the Company will need significant additional financing to develop the Project into an operating mine. The Company believes that financing for the Project can be secured if gold and silver remain at or near to the levels used for the updated cash flow analyses. Refer to Cash Flow Analyses above. Gold and silver prices averaged $1,224.53/oz and $20.19/oz in 2010 and the London pm fix closing prices on May 13, 2011 were $1505.75/oz and $36.20/oz respectively.

The Company is evaluating various financing options for the Project and these may be combined:

It is not expected that the Company will hedge any of its gold or silver production.

The ability of the Company to put the Project into production is subject to numerous risks, certain of which are disclosed in the Company’s latest Form 10-K filing with the SEC. Readers should evaluate the Company’s prospects in light of these and other risk factors.

Application of Critical Accounting Estimates

The financial statements of the Company have been prepared in accordance with generally accepted accounting principles in the United States. Because a precise determination of many assets and liabilities is dependent upon future events, the preparation of financial statements for a period necessarily involves the use of estimates which have been made using careful judgment.

The financial statements have, in management’s opinion, been properly prepared within reasonable limits of materiality and within the framework of the significant accounting policies summarized below:

Mineral Property and Exploration Costs

Exploration costs are expensed as incurred. Development costs are expensed until it has been established that a mineral deposit is commercially mineable and a production decision has been made by the Company to implement a mining plan and develop a mine, at which point the costs subsequently incurred to develop the mine on the property prior to the start of mining operations are capitalized.

The Company capitalizes the cost of acquiring mineral property interests, including undeveloped mineral property interests, until the viability of the mineral interest is determined. Capitalized acquisition costs are expensed if it is determined that the mineral property has no future economic value. Exploration stage mineral interests represent interests in properties that are believed to potentially contain (i) other mineralized material such as measured, indicated or inferred resources with insufficient drill hole spacing to qualify as proven and probable mineral reserves and (ii) other mine-related or green field exploration potential that are not an immediate part of measured or indicated resources. The Company’s mineral rights are generally enforceable regardless of whether or not proven and probable reserves have been established. The Company has the ability and intent to renew mineral rights where the existing term is not sufficient to recover undeveloped mineral interests.

Capitalized amounts (including capitalized development costs) are also written down if future cash flows, including potential sales proceeds, related to the mineral property are estimated to be less than the property’s total carrying value. Management reviews the carrying value of each mineral property periodically, and, whenever events or changes in circumstances indicate that the carrying value may not be recoverable, makes the necessary adjustments. Reductions in the carrying value of a property would be recorded to the extent that the total carrying value of the mineral property exceeds its estimated fair value. A write-down of $370,956 in mineral property interests was recorded for the period ended March 31, 2011 (2010 - $Nil)

Asset Retirement Obligations

In accordance with the Accounting for Asset Retirement Obligations, the fair value of an asset retirement cost, and corresponding liability, should be recorded as part of the cost of the related long-lived asset and subsequently allocated to expense using a systematic and rational method. The Company has recorded an asset retirement obligation to reflect its legal obligations related to future abandonment of its mineral property using estimated expected cash flow associated with the obligation and discounting the amount using a credit-adjusted, risk-free interest rate. At least annually, the Company reassesses the obligation to determine whether or not a change in any estimated obligation is necessary. The asset retirement obligation recorded as a liability on the Interim Consolidated Balance Sheet is $197,900 as at March 31, 2011 (December 31, 2010 - $193,545).

Derivative Liabilities

Our stock options are denominated in a currency other than our functional currency and the instruments were required to be accounted for as separate derivative liabilities. These liabilities were required to be measured at fair value. These instruments were adjusted to reflect fair value at each period end. Any increase or decrease in the fair value was recorded in results of operations as change in fair value of derivative liabilities. In determining the appropriate fair value, we used the Black-Scholes pricing model.

Recently Issued Accounting Standards

A summary of Recently Issued Accounting Standards is provided in Item 7 of the Company’s latest Form 10-K filing with the SEC.

Qualified Person and Caution With Respect to Forward-looking Statements

Mr. H. Lutz Klingmann, P.Eng., the president of the Company, is a qualified person for the purposes of National Instrument 43-101 and has reviewed and approved the technical information in this report.

This report contains certain forward-looking statements, which relate to the intent, belief and current expectations of the Company’s management. These forward-looking statements are based upon numerous assumptions that involve risks and uncertainties and other factors that may cause actual results to differ materially from those indicated by such forward-looking statements. Such factors include among other things the receipt of required approvals and permits, the costs of and availability of sufficient capital to fund the projects to be undertaken by the Company, commodity prices and other factors. Readers are cautioned not to place undue reliance on the forward-looking statements, which speak only as of the date the statements were made.

Caution to U.S. Investors

Management advises U.S. investors that while the terms “measured resources”, “indicated resources” and “inferred resources” are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize these terms. U.S. investors are cautioned not to assume that any part or all of the material in the mineral resource categories will be converted into mineral reserves. References to such terms are contained in the Company’s Form 10-K and other publicly available filings. We further advise U.S. investors that the mineral reserve estimates disclosed in this report have been prepared in accordance with Canadian regulations and may not qualify as “reserves under the U.S. Securities and Exchange Commission Industry Guide 7. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information presented by companies using only U.S. standards in their public disclosure.

Item 4.     Controls and Procedures

Disclosure of Controls and Procedures

Disclosure controls and procedures and other procedures that are designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time period specified in the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and

communicated to management including our Chief Executive Officer and Chief Financial Officer as appropriate, to allow timely decisions regarding required disclosure.

Evaluation of disclosure controls and procedures and remediation

Management, including the principal executive officer and the principal financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e)) as of the end of the period covered by this report. Based on that evaluation, management concluded that as of the end of the period covered by this report, our disclosure controls and procedures were not effective. This includes those controls and procedures necessary to ensure that information required to be disclosed in reports filed or submitted with the SEC (i) is recorded, processed, and reported within the time periods specified by the SEC, and (ii) is accumulated and communicated to management, including our principal executive officer and principal financial officer, as appropriate to allow for timely decisions regarding required disclosure. The conclusion that our disclosure controls and procedures for financial reporting were not effective for the interim period ended March 31, 2011, was a result of our recognition that certain detailed reviews of our financial disclosure was not performed in a timely manner, that there is inadequate internal technical expertise required to address certain accounting and tax issues, and that there exists an inherent limitation due to the lack of segregation of duties of management.

There have been no changes in our internal controls over financial reporting that occurred during this period that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

Limitations on the effectiveness of disclosure controls and procedures

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