Notes to Condensed Consolidated Interim financial Statements (unaudited) 
 
(Expressed in U.S. Dollars, unless otherwise noted) 
 
Three Months Ended March 31, 2011 
 
    1.Nature of operations 
 
    Greystar  Resources  Ltd. (the "Company") is a publicly listed company incorporated  in  Canada  under  the 
    legislation  of  the Province of British Columbia.  The Company's shares are listed on  the  Toronto  Stock 
    Exchange  ("TSX") and the Alternative Investment Market ("AIM") of the London Stock Exchange. The Company's 
    principal business activities include the acquisition, exploration and development of mineral properties. 
 
    The  Company is in the process of exploring its mineral properties and has not yet determined whether  they 
    contain  reserves that are economically recoverable.  Management anticipates that the Company will continue 
    to  raise  adequate  funding through equity or debt financings, although there is  no  assurance  that  the 
    Company  will  be able to obtain adequate funding on favorable terms.  The recoverability of amounts  shown 
    for  mineral  properties and equipment is dependent upon, among other things, the discovery of economically 
    recoverable  reserves, the ability of the Company to obtain the necessary financing to complete exploration 
    and  development,  confirmation of the Company's interest in the underlying concessions and  licenses,  the 
    ability  of  the  Company to obtain the necessary mining and environmental permits, and  future  profitable 
    production or proceeds from the disposition of the mineral properties. 
 
    At  March  31,  2011,  the Company had working capital of $81,338,571 but had not yet  achieved  profitable 
    operations  and expects to incur further losses in the development of its business.  For the  three  months 
    ended March 31, 2011, the Company reported a comprehensive loss of $3,615,977 and as at March 31, 2011, had 
    an  accumulated  deficit of $152,313,762.  The ability of the Company to continue as  a  going  concern  is 
    dependent  upon  the Company's ability to arrange additional financing to complete the development  of  its 
    property,  including  obtaining  the  necessary permits and other regulatory  approvals,  and  upon  future 
    profitable operations. 
 
    2.Basis of preparation 
 
         (a)Statement of compliance 
 
               These condensed consolidated interim financial statements have been prepared in accordance  with 
               International  Accounting Standard 34 Interim Financial Reporting ("IAS 34") as  issued  by  the 
               International  Accounting  Standards  Board ("IASB"). The  policies  applied  in  these  interim 
               financial  statements are based on International Financial Reporting Standards  ("IFRS")  issued 
               and  outstanding  as  at  May 11, 2011, the date the Board of Directors approved  these  interim 
               financial statements for issue. Any subsequent changes to IFRS that are issued and effective  as 
               at  December  31,  2011,  could result in a restatement of these interim  financial  statements, 
               including the transition adjustments recognized on conversion to IFRS. 
 
               These  are  the Company's first condensed consolidated interim financial statements prepared  in 
               accordance  with IFRS and, as a result, IFRS 1, "First-time Adoption of International  Financial 
               Reporting  Standards," has been applied. Prior to the adoption of IFRS, the Company's  financial 
               statements  were  prepared in accordance with Canadian generally accepted accounting  principles 
               ("Canadian  GAAP").  As  these interim financial statements are the  Company's  first  financial 
               statements prepared in accordance with IFRS, disclosure of the elected transition exemptions and 
               reconciliation and explanation of accounting policy differences compared to Canadian  GAAP  have 
               been provided in Note 14. 
 
               These  interim financial statements should be read in conjunction with the Company's 2010 annual 
               financial  statements,  which  were prepared in accordance with  Canadian  GAAP,  and  the  IFRS 
               disclosures included in Note 14. 
 
         (b)Basis of measurement 
 
               The consolidated interim financial statements have been prepared on the historical cost basis in 
               the  statement of financial position except for certain derivative financial instruments,  which 
               are measured at fair value. 
 
         (c)Functional and presentation currency 
 
               These  interim condensed consolidated financial statements are presented in U.S. dollars,  which 
               is the Company's functional currency. 
 
         (d)Use of estimates and judgements 
 
               The  preparation  of  the condensed consolidated financial statements in  conformity  with  IFRS 
               requires management to make judgements, estimates and assumptions that affect the application of 
               accounting policies and the reported amounts of assets, liabilities, income and expenses. Actual 
               results may differ from these estimates. 
 
               Estimates  and underlying assumptions are reviewed on an ongoing basis. Revisions to  accounting 
               estimates  are  recognized in the period in which the estimates are revised and  in  any  future 
               periods affected. 
 
                     (i)Critical accounting estimates 
 
                         Critical  accounting estimates are estimates and assumptions made by  management  that 
                         may  result  in a material adjustment to the carrying amount of assets and liabilities 
                         within the next financial year and are as follows: 
 
                         Site restoration provision 
 
                         The  Company assesses its site restoration provision annually.  Significant  estimates 
                         and  assumptions are made in determining the site restoration provision as  there  are 
                         numerous  factors  that  will affect the ultimate liability  payable.   These  factors 
                         include  estimates of the extent and costs of rehabilitation activities, technological 
                         changes,  regulatory  changes, cost increases, and changes in discount  rates.   Those 
                         uncertainties  may  result  in future actual expenditure  differing  from  the  amount 
                         currently provided.  The provision at the date of the statement of financial  position 
                         represents  management's  best  estimate of the  present  value  of  the  future  site 
                         restoration costs required.  Changes to estimated future costs are recognized  in  the 
                         statement  of  financial  position  by  adjusting  the  site  restoration  asset   and 
                         liability.  To  the  extent that the site restoration provision  was  created  due  to 
                         exploration activities, the amount capitalized is reduced immediately by a  charge  to 
                         exploration expenses for the same amount. 
 
                         Exploration and evaluation assets 
 
                         The  application  of  the  Company's  accounting  policy  for  and  determination   on 
                         recoverability   of  capitalized  exploration  and  evaluation  expenditure   requires 
                         judgement  in  determining whether future economic benefits are likely, which  may  be 
                         based  on assumptions about future events or circumstances.  Estimates and assumptions 
                         made  may  change  if  new information becomes available.  If,  after  expenditure  is 
                         capitalized,   information  becomes  available  suggesting  that   the   recovery   of 
                         expenditure  is unlikely, the amount capitalized is recognized in loss in  the  period 
                         that the new information becomes available. 
 
                         Warrants and stock options issued with Canadian dollar exercise prices 
 
                         The  fair  value  of warrants and stock options issued with Canadian  dollar  exercise 
                         prices  are  subject to the limitation of the Black-Scholes option pricing model that 
                         incorporates  market data and involves uncertainty in estimates used by management in 
                         the assumptions. Because the Black-Scholes option pricing model requires the input of 
                         highly  subjective  assumptions, including the volatility of share price, changes in 
                         subjective input assumptions can materially affect the fair value estimate. 
 
                         Recovery of deferred tax assets 
 
                         Judgement  is  required in determining whether deferred tax assets are  recognized  in 
                         the  statement  of financial position.  Deferred tax assets, including  those  arising 
                         from  unutilized  tax  losses, require management to assess the  likelihood  that  the 
                         Company  will  generate  taxable  earnings in future  periods,  in  order  to  utilize 
                         recognized  deferred  tax assets.  Estimates of future taxable  income  are  based  on 
                         forecast cash flows from operations and the application of existing tax laws  in  each 
                         jurisdiction.   To  the  extent  that future cash  flows  and  taxable  income  differ 
                         significantly from estimates, the ability of the Company to realize the  net  deferred 
                         tax  assets  recorded  at  the date of the statement of financial  position  could  be 
                         impacted. 
 
                         Additionally,  future changes in tax laws in the jurisdictions in  which  the  Company 
                         operates  could  limit the ability of the Company to obtain tax deductions  in  future 
                         periods. 
 
                     (ii)Critical accounting judgements 
 
                         Information  about critical judgements in applying accounting policies that  have  the 
                         most  significant  effect  on  the amounts recognized in  the  condensed  consolidated 
                         financial statements are as follows: 
 
                         Determination of functional currency 
 
                         In  accordance  with  IAS  21,  "The Effects of Changes in  Foreign  Exchange  Rates," 
                         management determined that the functional currencies of Greystar Resources  Ltd.,  its 
                         Colombian branch and subsidiaries are the U.S. dollar. 
 
    3.Significant accounting policies 
 
         (a)Basis of consolidation 
 
               These  condensed consolidated interim financial statements include the accounts of the  Company, 
               its  Colombian  branch  and  subsidiaries. Intra-company  balances  and  transactions,  and  any 
               unrealized  income  and  expenses  arising from intra-company transactions,  are  eliminated  in 
               preparing the consolidated financial statements. 
 
         (b)Foreign currency translation 
 
               Transactions  in  foreign  currencies are initially translated to U.S. dollars,  the  functional 
               currency of Company, at exchange rates at the dates of the transactions. 
 
               Monetary  assets  and liabilities denominated in foreign currencies at the  reporting  date  are 
               retranslated to the functional currency at the exchange rate at that date. 
 
               Non-monetary  items  that are measured in terms of historical cost in  a  foreign  currency  are 
               translated  using  the  exchange rate at the date of the transaction.  Non-monetary  assets  and 
               liabilities  denominated in foreign currencies that are measured at fair value are  retranslated 
               to the functional currency at the exchange rate at the date that the fair value was determined. 
 
               Foreign currency differences arising on retranslation are recognized in profit or loss. 
 
         (c)Property, plant and equipment 
 
               Property,  plant and equipment are recorded at cost less accumulated depreciation.  Depreciation 
               is recognized in profit or loss on a straight-line basis over the estimated useful lives of each 
               part  of an item of property, plant and equipment, since this most closely reflects the expected 
               pattern  of  consumption of the future economic benefits embodied in the  asset.  The  estimated 
               useful lives for the current and comparative periods are as follows: 
 
                  --  Buildings        20 years 
                  --  Field equipment  3 to 5 years 
                  --  Office equipment 3 years 
                  --  Transport        5 years. 
 
         (d)Exploration and evaluation assets 
 
               All  direct costs related to the acquisition of mineral property interests are capitalized  into 
               intangible  assets. Exploration and evaluation expenditures incurred prior to the  determination 
               of  the  feasibility of mining operations and a decision to proceed with development are charged 
               to  operations  as  incurred.   Development expenditures incurred subsequent  to  a  development 
               decision, and to increase or to extend the life of existing production, are capitalized and will 
               be amortized on the unit-of-production method based upon estimated proven and probable reserves. 
               When  there  is little prospect of further work on a property being carried out by the  Company, 
               the  remaining deferred costs associated with that property are charged to operations during the 
               period such determination is made. 
 
               The amounts shown for exploration and evaluation assets represent acquisition costs incurred  to 
               date, less recoveries and write-offs, and do not reflect fair value. 
 
         (e)Impairment of non-financial assets 
 
               The  carrying amounts of the Company's non-financial assets, other than deferred tax assets, are 
               reviewed  at each reporting date to determine whether there is any indication of impairment.  If 
               any such indication exists, then the asset's recoverable amount is estimated. 
 
               For  the  purpose of impairment testing, assets that cannot be tested individually  are  grouped 
               together into the smallest group of assets that generates cash inflows from continuing use  that 
               are  largely  independent of the cash inflows of other assets or groups of  assets  (the  "cash- 
               generating  unit," or "CGU").The recoverable amount of an asset or cash-generating unit  is  the 
               greater  of its value in use and its fair value less costs to sell. In assessing value  in  use, 
               the  estimated future cash flows are discounted to their present value using a pre-tax  discount 
               rate  that reflects current market assessments of the time value of money and the risks specific 
               to the asset. 
 
               The  Company's corporate assets do not generate separate cash inflows. If there is an indication 
               that a corporate asset may be impaired, then the recoverable amount is determined for the CGU to 
               which the corporate asset belongs. 
 
               An  impairment  loss  is recognized if the carrying amount of an asset or its  CGU  exceeds  its 
               estimated recoverable amount. Impairment losses are recognized in profit or loss. 
 
               Impairment  losses  recognized in prior periods are assessed at  each  reporting  date  for  any 
               indications  that the loss has decreased or no longer exists. An impairment loss is reversed  if 
               there has been a change in the estimates used to determine the recoverable amount. An impairment 
               loss  is  reversed  only  to the extent that the asset's carrying amount  does  not  exceed  the 
               carrying  amount  that would have been determined, net of depreciation or  amortization,  if  no 
               impairment loss had been recognized. 
 
         (f)Provisions 
 
               A  provision is recognized if, as a result of a past event, the Company has a present  legal  or 
               constructive  obligation that can be estimated reliably, and it is probable that an  outflow  of 
               economic  benefits  will  be  required to settle the obligation. Provisions  are  determined  by 
               discounting  the  expected  future cash flows at a pre-tax rate  that  reflects  current  market 
               assessments of the time value of money and the risks specific to the liability. The unwinding of 
               the discount is recognized as finance cost. 
 
         (g)Financial assets 
 
                     (i)Financial assets at fair value through profit or loss ("FVTPL") 
 
                         Financial assets at FVTPL are financial assets held for trading. A financial asset  is 
                         classified in this category if acquired principally for the purpose of selling in  the 
                         short  term  or  if so designated by management. Derivatives are also  categorized  as 
                         FVTPL  unless  they are designed as effective hedges. Assets in this category  include 
                         cash and cash equivalents. 
 
                         Financial assets at FVTPL are initially recognized, and subsequently carried, at  fair 
                         value,  with  changes recognized in profit or loss. Transaction costs are expensed  as 
                         incurred. 
 
                     (ii)Loans and receivables 
 
                         Loans  and  receivables are non-derivative financial assets with fixed or determinable 
                         payments  that  are  not  quoted in an active market. They  are  included  in  current 
                         assets,  except  for those with maturities greater than 12 months or  those  that  are 
                         expected  to  be settled after 12 months from the end of the reporting  period,  which 
                         are  classified as non-current assets. Assets in this category include trade and other 
                         receivables. 
 
                         Loans  and  receivables are initially recognized at fair value plus transaction  costs 
                         and  subsequently  carried  at  amortized cost using the  effective  interest  method, 
                         except  for  short-term  receivables  when  the  recognition  of  interest  would   be 
                         immaterial. 
 
                     (iii)Effective interest method 
 
                         The  effective interest method is used to determine the amortized cost of a  financial 
                         asset  and  to  allocate interest income over the corresponding period. The  effective 
                         interest  rate  is  the rate that discounts estimated future cash  receipts  over  the 
                         expected life of the financial asset, or, where appropriate, a shorter period. 
 
                         Income  is  recognized on an effective interest basis for debt instruments other  than 
                         those financial assets classified as FVTPL. 
 
                     (iv)Impairment of financial assets 
 
                         Financial  assets,  other  than  those  at  FVTPL,  are  assessed  for  indicators  of 
                         impairment  at each period end. Financial assets are impaired when there is  objective 
                         evidence  that,  as  a result of one or more events that occurred  after  the  initial 
                         recognition of the financial asset, the estimated future cash flows of the  investment 
                         have been impacted. 
 
                         Objective evidence of impairment could include the following: 
 
                             -- Significant financial difficulty of the issuer or counterparty; 
                             -- Default or delinquency in interest or principal payments; or 
                             -- It has become probable that the borrower will enter bankruptcy or financial 
                                reorganization. 
 
                         For  financial assets carried at amortized cost, the amount of the impairment  is  the 
                         difference between the asset's carrying amount and the present value of the  estimated 
                         future  cash  flows,  discounted at the financial asset's original effective  interest 
                         rate. 
 
                         The  carrying amount of all financial assets, excluding trade receivables, is directly 
                         reduced  by  the impairment loss. The carrying amount of trade receivables is  reduced 
                         through  the  use  of  an  allowance account. When a trade  receivable  is  considered 
                         uncollectible, it is written off against the allowance account. Subsequent  recoveries 
                         of  amounts previously written off are credited against the allowance account. Changes 
                         in the carrying amount of the allowance account are recognized in profit or loss. 
 
                         For  financial  assets  measured at amortized cost, if, in a  subsequent  period,  the 
                         amount  of  the impairment loss decreases and the decrease can be related  objectively 
                         to  an  event  occurring after the impairment losses were recognized,  the  previously 
                         recognized impairment loss is reversed through profit or loss to the extent  that  the 
                         carrying  amount of the asset at the date the impairment is reversed does  not  exceed 
                         what the amortized cost would have been had the impairment not been recognized. 
 
                     (v)Derecognition of financial assets 
 
                         Financial  assets  are derecognized when the rights to receive  cash  flows  from  the 
                         assets  expire or the financial assets are transferred and the Company has transferred 
                         substantially  all  the  risks and rewards of ownership of the  financial  assets.  On 
                         derecognition  of  a  financial  asset, the difference between  the  asset's  carrying 
                         amount  and  the  sum of the consideration received and receivable and the  cumulative 
                         gain  or  loss that had been recognized directly in equity is recognized in profit  or 
                         loss. 
 
         (h)Financial liabilities and equity 
 
               Debt  and  equity  instruments are classified as either financial liabilities or  as  equity  in 
               accordance  with  the  substance of the contractual arrangement. An  equity  instrument  is  any 
               contract  that evidences a residual interest in the assets of an entity after deducting  all  of 
               its  liabilities. Equity instruments issued by the group entities are recorded at  the  proceeds 
               received, net of direct issue costs. 
 
               Financial liabilities are classified as either financial liabilities at FVTPL or other financial 
               liabilities. 
 
               A financial liability may be designated as at FVTPL upon initial recognition if: 
 
                  -- Such designation eliminates or significantly reduces a measurement or recognition 
                     inconsistency that would otherwise arise; or 
                  -- The financial liability forms part of a group of financial assets or financial liabilities 
                     or both, which is managed and its performance is evaluated on a fair value basis, in 
                     accordance with the Company's documented risk management or investment strategy, and 
                     information about the grouping is provided internally on that basis; or 
                  -- It forms part of a contract containing one or more embedded derivatives and IAS 39 
                     permits the entire combined contract (asset or liability) to be designated as at FVTPL. 
 
               At  the end of each reporting period subsequent to initial recognition, financial liabilities at 
               FVTPL  are  measured at fair value, with changes in fair value recognized directly in profit  or 
               loss  in  the period in which they arise. Other financial liabilities are initially measured  at 
               fair value, net of transaction costs, and are subsequently measured at amortized cost using  the 
               effective interest method, with interest expense recognized on an effective yield basis. 
 
                     (i)Warrant liabilities: 
 
                         The  Company  has issued share purchase warrants with Canadian dollar exercise  prices 
                         (note  8)  in connection with equity financing arrangements. As a result, the proceeds 
                         from  the exercise of these warrants will vary. These warrants meet the definition  of 
                         derivatives  and  are therefore classified as financial liabilities  and  measured  at 
                         FVTPL prior to their exercise and expiry dates. 
 
                     (ii)Other financial liabilities: 
 
                         The Company has classified trade and other payables as other financial liabilities. 
 
                     (iii)Derecognition of financial liabilities: 
 
                         Financial  liabilities are derecognized when the obligation specified in the  relevant 
                         contract  is  discharged, cancelled or expires. The difference  between  the  carrying 
                         amount  of the financial liability derecognized and the consideration paid and payable 
                         is recognized in profit or loss. 
 
         (i)Share capital 
 
               The  Company  records  proceeds  from share issuances net of issue  costs.   Shares  issued  for 
               consideration other than cash are valued at the quoted market price on the date the agreement to 
               issue the shares was reached and announced for business combinations and at the date of issuance 
               for other non-monetary transactions.  For proceeds received from the issuance of compound equity 
               instruments  such  as units comprised of common shares and warrants, the Company  allocates  the 
               proceeds  using the residual method whereby the proceeds allocated to the warrants is  based  on 
               their Black-Scholes fair value with the remaining proceeds allocated to common shares. 
 
         (j)Loss per share 
 
               The  Company  presents basic and diluted earnings per share ("EPS") data for its common  shares. 
               Basic  EPS  is calculated by dividing the profit or loss attributable to common shareholders  of 
               the  Company  by  the  weighted average number of common shares outstanding during  the  period, 
               adjusted  for  own  shares held. Diluted loss per share is calculated using the  treasury  stock 
               method.   Under  the  treasury  stock  method, the weighted  average  number  of  common  shares 
               outstanding  for  the  calculation of diluted loss per share assumes that  the  proceeds  to  be 
               received  on  the exercise of dilutive share options and warrants are used to repurchase  common 
               shares at the average market price during the period. 
 
               In the Company's case, diluted loss per share is the same as basic loss per share, as the effect 
               of outstanding share options and warrants (see note 8) on loss per share would be anti-dilutive. 
 
         (k)Share-based payment transactions 
 
               The grant date fair value of share-based payment awards granted to employees is recognized as an 
               employee  expense, with a corresponding increase in equity, over the period that  the  employees 
               unconditionally become entitled to the awards. The amount recognized as an expense  is  adjusted 
               to  reflect the number of awards for which the related service and non-market vesting conditions 
               are expected to be met, such that the amount ultimately recognized as an expense is based on the 
               number  of awards that do meet the related service and non-market performance conditions at  the 
               vesting  date. For share-based payment awards with non-vesting conditions, the grant  date  fair 
               value  of the share-based payment is measured to reflect such conditions and there is no true-up 
               for differences between expected and actual outcomes. 
 
               Share-based   payment  arrangements  in  which  the  Company  receives  goods  or  services   as 
               consideration  for  its  own equity instruments are accounted for as equity-settled  share-based 
               payment transactions. 
 
         (l)Income taxes 
 
               Income  tax  expense  comprises  current and deferred tax. Current  tax  and  deferred  tax  are 
               recognized in profit or loss except to the extent that it relates to a business combination,  or 
               items recognized directly in equity or in other comprehensive income. 
 
               Current  tax  is the expected tax payable or receivable on the taxable income or  loss  for  the 
               year, using tax rates enacted or substantively enacted at the reporting date, and any adjustment 
               to tax payable in respect of previous years. 
 
               Deferred  tax is recognized in respect of temporary differences between the carrying amounts  of 
               assets  and  liabilities  for financial reporting purposes and the  amounts  used  for  taxation 
               purposes.  Deferred tax is not recognized for the following temporary differences:  the  initial 
               recognition  of  assets or liabilities in a transaction that is not a business  combination  and 
               that  affects  neither  accounting  nor taxable profit or  loss,  and  differences  relating  to 
               investments  in subsidiaries and jointly controlled entities to the extent that it  is  probable 
               that  they  will  not  reverse  in  the foreseeable future. In addition,  deferred  tax  is  not 
               recognized  for  taxable temporary differences arising on the initial recognition  of  goodwill. 
               Deferred  tax  is  measured  at  the tax rates that are expected  to  be  applied  to  temporary 
               differences when they reverse, based on the laws that have been enacted or substantively enacted 
               by  the  reporting date. Deferred tax assets and liabilities are offset if there  is  a  legally 
               enforceable right to offset current tax liabilities and assets, and they relate to income  taxes 
               levied  by the same tax authority on the same taxable entity, or on different tax entities,  but 
               they intend to settle current tax liabilities and assets on a net basis or their tax assets  and 
               liabilities will be realized simultaneously. 
 
               A  deferred tax asset is recognized for unused tax losses, tax credits and deductible  temporary 
               differences,  to  the extent that it is probable that future taxable profits will  be  available 
               against which they can be utilized. Deferred tax assets are reviewed at each reporting date  and 
               are  reduced  to the extent that it is no longer probable that the related tax benefit  will  be 
               realized.

    5.Exploration and evaluation assets 
 
    The  Company's  exploration and evaluation assets comprise mineral property surface rights, mining  titles, 
    exploration licenses, exploitation permits and concession contracts that provide for gold, silver and other 
    precious  metals  exploitation in an area located in the Municipality of California,  Santander,  Colombia, 
    collectively  known as the Angostura Project. The licenses, permits and contracts expire at  various  dates 
    ranging  from  2020 to 2038 and generally can be renewed for an additional 10, 20 or 30 years depending  on 
    the applicable mining code. Certain portions of the Angostura project are subject to royalties ranging from 
    5%  to  10%  of  net  profits after certain additional deductions. In addition, pursuant  to  the  laws  of 
    Colombia, the Government of Colombia currently receives royalties on gold and silver production equal to 4% 
    of  80% of the production value, which is calculated using the average gold and silver prices published  by 
    the London Metal Exchange. 
 
    In  order  to maintain the Company's mineral properties in good standing, the Company is required  to  make 
    certain annual fee payments based on the number of hectares and a Colombian wage factor that fluctuates  on 
    an  annual basis.  As at March 31, 2011, the required annual fee payments related to the Company's  mineral 
    properties totaled approximately $624,000 (2010 - $634,000). 
 
    The following is a reconciliation of the carrying amounts of exploration and evaluation assets.

    Additions  to exploration and evaluation assets during the three months ended March 31, 2011, relate  to  a 
    combination  of $526,728 cash consideration and 35,000 share purchase warrants issued. The warrants  issued 
    to  purchase  the  Company's common shares have a term of 4 years with an exercise price  of  Cdn$3.69  and 
    maturity  date  of January 20, 2015. The value of the share purchase warrants issued was  estimated  to  be 
    $74,350  using the Black-Scholes valuation model applying risk free rate of 2.23%, expected life  based  on 
    the full term of the warrants, expected dividends of nil, and volatility rate of 84.5%.

    7.Site restoration provision 
 
        As  at  March  31,  2011, the Company had a site restoration provision of $862,159  (2010  -  $997,646) 
        relating  to the remediation of environmental disturbances at the Angostura project.  The provision  is 
        based  on  $1,195,783  of undiscounted estimated cash flows required to settle  the  provision  in  the 
        future.   Assumptions  used  by management to determine the carrying amount  of  the  site  restoration 
        provision were a 6.59% pre-tax risk-free discount rate, and a 3.38 - 3.75% rate of inflation  over  the 
        expected years to settlement, which is estimated to be in 2013. 
 
        The  following  table  shows  the  changes in the carrying amount of  the  Company's  site  restoration 
        provision associated with the Angostura project:

    8.Share capital 
 
    (a)Authorized: 
 
        Unlimited common shares without par value 
 
    (b)Issued and outstanding: 
 
        The  Company had 84,222,987 common shares issued and outstanding as of March 31, 2011 and December  31, 
        2010. 
 
     (c)Stock options: 
 
        The  Company  has  an  incentive share option plan (the Plan) that allows it to grant  options  to  its 
        employees,  officers,  directors  and  consultants to acquire common  shares.   The  number  of  shares 
        issuable  pursuant to the Plan is a fixed maximum percentage of 10% of the common shares issued.  Under 
        the  terms  of  the  Plan, the exercise price of each option equals the closing market  price  for  the 
        common  shares  on the TSX on the trading day prior to the date of the grant.  Options have  a  maximum 
        term  of  ten years and terminate sixty days following the termination of the optionee's employment  or 
        term  of engagement, except in the case of retirement, or death, termination for cause, resignation  at 
        the  request  of the Board, removal or disqualification.  Vesting of options is made at the  discretion 
        of the Board of Directors at the time the options are granted. 
 
        The  share  option plan also provides for a cashless exercise option provision which is in substance  a 
        stock  appreciation  right  and  for which the stock options can only  be  equity-settled.  When  share 
        capital  recognized  as equity is repurchased as a result of the cashless option,  the  amount  of  the 
        consideration  paid, which includes directly attributable costs, net of any tax effects, is  recognized 
        as  a deduction from equity. Repurchased shares are classified as treasury shares and are presented  as 
        a  deduction  from  total  equity. When treasury shares are sold or reissued subsequently,  the  amount 
        received  is  recognized  as  an  increase in equity, and the  resulting  surplus  or  deficit  on  the 
        transaction is transferred to/from retained earnings.

        31, 2010 were as follows:

        As  at  March 31, 2011, with other variables unchanged, a 10% depreciation or appreciation of the  U.S.

        instruments  and  would  affect  the consolidated statement of operations  and  comprehensive  loss  by 
        approximately $338,127. 
 
        The  Company's exposure to the Colombia peso on quarterly exploration expenditures throughout the three 
        months  ended  March 31, 2011 was $4.8 million. A 10% depreciation or appreciation of the  U.S.  dollar 
        against  the  Colombian  peso would affect the consolidated statement of operations  and  comprehensive 
        loss by approximately $484,258. 
 
        The  Company's  exposure  to the Canadian dollar, expressed in U.S dollars  and  Canadian  dollars,  on 
        financial instruments is as follows:

        As  at  March 31, 2011, with other variables unchanged, a 10% depreciation or appreciation of the  U.S. 
        dollar  against  the  Canadian  dollar  would change the values  of  the  Canadian  dollar  denominated 
        financial instruments and would affect the consolidated statement of operations and comprehensive  loss 
        by approximately $9,286,055. 
 
        The  Company's  exposure  to the Canadian dollar on quarterly exploration expenditures  throughout  the 
        three  months ended March 31, 2011 was $516,430. A 10% depreciation or appreciation of the U.S.  dollar 
        against  the  Canadian dollar would affect the consolidated statement of operations  and  comprehensive 
        loss by approximately $51,643. 
 
    (b)Credit risk: 
 
        Credit risk is the risk of an unexpected loss if a third party to a financial instrument fails to  meet 
        its  contractual obligations.  The Company manages its credit risk through its counterparty ratings and 
        credit limits. 
 
        The  Company's  cash  and cash equivalents and short term investments are held through  large  Canadian 
        financial  institutions.   Short-term  investments are composed  of  financial  instruments  issued  by 
        Canadian  banks and companies with high investment-grade ratings.  These instruments mature at  various 
        dates  over  the  current  operating period and are normally cashable on  a  designated  monthly  date. 
        Amounts  receivable  primarily  consists of HST receivable with  expected  payment  from  the  Canadian 
        government. 
 
        The  total cash and cash equivalents and amounts receivable represent the maximum credit exposure.  The 
        Company  limits  its credit risk exposure by holding bank accounts and any short term investments  with 
        reputable banks with high credit ratings. 
 
     (c)Liquidity risk: 
 
        The  Company  manages liquidity risk by maintaining adequate cash balances in order to meet  short  and 
        long  term business requirements.  The Company believes that these sources will be sufficient to  cover 
        its  cash  requirements  for the upcoming year.  The Company's cash is invested in  liquid  investments 
        with  quality financial institutions and is available on demand for the Company's programs and  is  not 
        invested in any asset backed commercial paper. 
 
        As at March 31, 2011, the Company's liabilities have contractual maturities as summarized below: 
 
                                                                                                     Less than 
                                                                                         Total          1 year

         Amounts payable on exploration and evaluation asset acquisition             1,140,516       1,140,516 
                                                                                 $   5,614,703     $ 5,614,703 
     (d)Interest rate risk: 
 
        Interest rate risk is the risk that the fair value or future cash flows of a financial instrument  will 
        fluctuate  because  of  changes in market interest rates. The Company's  bank  accounts  earn  interest 
        income  at  variable rates.  The Company's future interest income is exposed to changes  in  short-term 
        rates.  An  increase  or  decrease in the annual interest rate of 1% would result  in  a  corresponding 
        increase or decrease of annual interest income by $910,976. 
 
    (e)Fair value of financial instruments 
 
        The  fair  values of amounts receivable and accounts payable and accrued liabilities approximate  their 
        carrying  values  due  to the short-term nature of these instruments. The fair  value  of  the  amounts 
        payable  on  mineral property acquisitions approximates their carrying value as there was  no  material 
        change to the discount rate used to calculate the fair value since initial recognition. 
 
        There  are  three levels of the fair value hierarchy that prioritize the inputs to valuation techniques 
        used  to  measure  fair  value, with Level 1 inputs having the highest priority.  The  levels  and  the 
        valuation techniques used to value financial assets and liabilities are described below: 
 
            (i)Level 1 - Quoted Prices in Active Markets for Identical Assets 
 
                 Unadjusted  quoted  prices in active markets that are accessible at the measurement  date  for 
                 identical, unrestricted assets or liabilities. 
 
                 Cash  equivalents, including demand deposits and money market instruments,  are  valued  using 
                 quoted  market prices. Marketable equity securities are valued using quoted market  prices  in 
                 active  markets, obtained from securities exchanges. Accordingly, these items are included  in 
                 Level 1 of the fair value hierarchy. 
 
            (ii)Level 2 - Significant Other Observable Inputs 
 
                 Quoted  prices in markets that are not active, quoted prices for similar assets or liabilities 
                 in  active  markets,  or  inputs  that  are observable, either  directly  or  indirectly,  for 
                 substantially the full term of the asset or liability. 
 
            (iii)Level 3 - Significant Unobservable Inputs 
 
                 Unobservable (supported by little or no market activity) prices. 
 
        The  following table illustrates the classification of the Company's financial instruments recorded  at 
        fair value within the fair value hierarchy as at March 31, 2011. 
 
                                                                 Financial assets at fair value

    13.Subsequent events 
 
    In  April 2011, the Company announced various management and board changes that were effective in March and 
    April  2011. Various commitments have been recorded as a result of these changes in management. As at March 
    31, 2011, the Company accrued $232,223 as termination payments. As of April 2011, the Company has committed 
    $1,649,593  as termination payments. These termination payments will be paid over a period of  one  to  six 
    months commencing in April 2011. 
 
    On  May  3,  2011, the Company announced its decision to cancel the listing of its shares on  AIM  with  an 
    effective date of June 3, 2011. The Company's shares will continue to trade on the TSX. 
 
    14.First time adoption of IFRS 
 
    The Company adopted IFRS on January 1, 2011 with a transition date of January 1, 2010.  IFRS 1, "First-time 
    adoption  of  International Financial Reporting Standards", provides guidance for the initial  adoption  of 
    IFRS.  IFRS 1 requires retrospective application of the standards in the transition statement of  financial 
    position,  with  all  adjustments to assets and liabilities taken to deficit unless certain  mandatory  and 
    optional exemptions are applied. 
 
    The Company has applied the following exemptions to its opening statement of financial position: 
 
    (a)Business combinations 
 
        The  Company has elected to not apply IFRS 3 to business combinations that occurred before the date  of 
        transition  to  IFRS,  which  is an election permitted on first-time  adoption  of  IFRS.   IFRS  3  is 
        applicable for business combinations occurring on or after January 1, 2010. 
 
     (b)Cumulative foreign currency translation differences 
 
        As  permitted  by  the  IFRS  1 election for cumulative foreign currency translation  differences,  the 
        Company  has  deemed cumulative foreign currency translation differences for foreign operations  to  be 
        zero  at  the  date  of transition.  Any gains and losses on subsequent disposal of foreign  operations 
        will not be impacted by translation differences that arose prior to the date of transition. 
 
    (c)Share-based payments 
 
        Under  IFRS  1,  a first time adopter can elect not to apply IFRS 2, "Share-based Payment,"  to  share- 
        based  payments granted after November 7, 2001, that vested the later of (a) the date of the transition 
        and  (b)  January 1, 2005. The Company has elected to apply this exemption and to apply IFRS 2 only  to 
        awards  unvested at the January 1, 2010, date of transition.  IFRS has not been applied to awards  that 
        vested prior to January 1, 2010. 
 
    (d)Compound financial instruments 
 
        The  Company  has  elected to apply the exemption related to compound financial instruments  where  the 
        liability  component  is no longer outstanding at the date of transition to IFRS.  IAS  32,  "Financial 
        Instruments:  Presentation," requires an entity to split a compound financial instrument  at  inception 
        into  its separate liability and equity components. If the liability component is no longer outstanding 
        at  the  IFRS transition date, a first-time adopter need not separate the impact of compound  financial 
        instruments between the respective components of equity. 
 
    (e)Site restoration provision 
 
        IFRS  1  allows first time adopters to not fully comply with the requirements of IFRIC 1,  "Changes  in 
        Existing  Decommission, Restoration and Similar Liabilities," for such liabilities outstanding  at  the 
        IFRS  transition  date and instead apply a simplified method as set out in IFRS  1.   The  Company  has 
        elected  to apply this exemption related to site restoration provisions.  IFRIC 1 dealing with  changes 
        in site restoration provisions will be applied on a prospective basis from the date of transition. 
 
    (f)Leases 
 
        The  Company has elected to apply the IFRS exemption with respect to leases. This election  allows  the 
        Company  to  apply  the  transitional provisions of IFRIC Interpretation  4,  "Determining  Whether  an 
        Arrangement  Contains a Lease," to determine whether an arrangement existing at the date of  transition 
        to IFRS contains a lease on the basis of facts and circumstances existing at that date. 
 
    (g)Borrowing costs 
 
        Borrowing  costs related to the acquisition, construction or production of qualifying  assets  must  be 
        capitalized  under  IAS 23, "Borrowing Costs." In accordance with IFRS 1, the Company  has  elected  to 
        prospectively apply IAS 23 effective January 1, 2010. 
 
    (h)Estimates 
 
        IFRS  1  requires  that  an entity's estimates under IFRS at the date of transition  to  IFRS  must  be 
        consistent  with  estimates made for the same date under the entity's previous GAAP,  unless  there  is 
        objective  evidence that those estimates were in error.  The Company's IFRS estimates as of January  1, 
        2010 are consistent with its Canadian GAAP estimates for the same date. 
 
    IFRS  employs  a  conceptual framework that is similar to Canadian GAAP; however,  significant  differences 
    exist  in  certain areas of recognition, measurement and disclosure. While the adoption  of  IFRS  has  not 
    changed  the  actual  cash  flows of the Company, the adoption has resulted in  changes  to  the  Company's 
    reported  financial  position  and results of operations. In order to allow financial  statement  users  to 
    better  understand  these changes, the Company's Canadian GAAP opening statement of financial  position  at 
    January 1, 2010, and interim statements of financial position at March 31, 2010 and December 31, 2010,  and 
    statements  of comprehensive loss, and cash flows for the three months ended March 31, 2010, and  the  year 
    ended  December 31, 2010, have been reconciled to IFRS and presented below, along with explanations of  the 
    resulting differences. 
 
    The  Company's Canadian GAAP statement of financial position as at January 1, 2010, has been reconciled  to 
    IFRS as follows: 
 
                                                                January 1, 2010

    Explanatory notes to the IFRS reconciliations above 
 
        (i)Functional currency 
 
    Under  Canadian  GAAP  -  An entity is not explicitly required to assess the unit  of  measure  (functional 
    currency) in which it measures its own assets, liabilities, revenues and expenses.  Under Canadian GAAP, an 
    entity  applies criteria to determine only whether a foreign subsidiary's operation is integrated or  self- 
    sustaining, in which case the temporal or current methods of translation respectively, are then applied  to 
    the  subsidiary's financial statement balances and results of operations.  Under Canadian GAAP, the Company 
    prepared  its  financial  statements in Canadian dollars and its Colombian  branch  and  subsidiaries  were 
    determined to be integrated foreign operations. 
 
    Under  IFRS  - The functional currency of the reporting entity and each of its foreign operations  must  be 
    assessed  independently giving consideration to the primary economic environment in  which  each  operates. 
    IFRS  provides  guidance  in  respect  of factors to be considered in determining  an  entity's  functional 
    currency that are similar to those noted in Canadian GAAP, however unlike Canadian GAAP, IFRS distinguishes 
    between  primary and secondary factors in making such an assessment.  Based on the assessment  under  IFRS, 
    management  has determined that the functional currencies of Greystar Resources Ltd., its Colombian  branch 
    and  subsidiaries are the U.S. dollar as this is the currency of the primary economic environment in  which 
    the  Company operates.  Accordingly, the change in functional currency has been reflected in reporting  the 
    Company's financial position and results of operations under IFRS. 
 
        (ii)Change in presentation currency 
 
    The  Company  previously presented its financial statements in Canadian dollars. Under IFRS, the  Company's 
    financial  statements  are presented in U.S. dollars, the same as its functional currency.  The  change  in 
    presentation  currency results in a cumulative translation adjustment and under IFRS  1,  the  Company  has 
    elected to eliminate the cumulative translation adjustment on the IFRS transition date. 
 
        (iii)Share-based payments 
 
    Under  Canadian GAAP - The fair value of stock-based awards with graded vesting are calculated as one grant 
    and the resulting fair value is recognized on a straight-line basis over the vesting period. Forfeitures of 
    awards are recognized as they occur. 
 
    Under  IFRS - Each tranche of an award with different vesting dates is considered a separate grant for  the 
    calculation  of  fair  value, and the resulting fair value is amortized over the  estimated  lives  of  the 
    respective tranches. Forfeiture estimates are recognized in the period they are estimated, and are  revised 
    for actual forfeitures in subsequent periods. 
 
        (iv)Share purchase warrants 
 
    Under  Canadian  GAAP  -  The  Company's share purchase warrants are measured  at  fair  value  at  initial 
    recognition using the Black-Scholes option pricing model, and recorded in equity reserve with no subsequent 
    re-measurement. 
 
    Under  IFRS  -  The exercise prices of the Company's share purchase warrants that are issued in  connection 
    with  the  issuance  of  equity are denominated in Canadian dollars, which is not the Company's  functional 
    currency.  As a result, the proceeds from the exercise of these warrants will vary. These warrants meet the 
    definition of derivatives under IAS 32 and are therefore, classified as liabilities and measured  at  FVTPL 
    at  grant  date  and  the  end of each reporting period. The Company's share purchase  warrants  issued  as 
    compensation  for mineral property acquisitions and agents' commissions for share issuances  are  accounted 
    for under IFRS 2 and are classified as equity. The adoption of IFRS had no impact on these warrants. 
 
        (v)Compound financial instruments 
 
    Under  Canadian GAAP - The Company raised equity by issuing units that consisted of common shares and share 
    purchase warrants. The gross proceeds were allocated to common shares and warrants using the relative  fair 
    value method. 
 
    Under  IFRS - IAS 32 requires an entity to split a compound financial instrument at inception into separate 
    liability  and  equity components. For proceeds received from the issuance of compound  equity  instruments 
    such  as  units  comprised  of common shares and warrants, the Company allocated  the  proceeds  using  the 
    residual  method whereby the proceeds allocated to the warrants is based on their Black-Scholes fair  value 
    with the remaining proceeds allocated to common shares. 
 
        (vi)Site restoration provision 
 
    Under  Canadian  GAAP  -  The  Company uses the best estimate that a  third  party  would  charge  for  the 
    remediation  work  to measure the reclamation and closure cost obligations. The Company  uses  the  credit- 
    adjusted  pre-tax  risk-free  interest  rate  as a discount rate  to  measure  the  net  present  value  of 
    undiscounted estimated future cash flows. 
 
    Under IFRS - Under IAS 37, reclamation and closure cost obligations are measured based on management's best 
    estimate  of the expenditures required to settle the obligations as at the balance sheet date. In the  case 
    that  management intends to perform the reclamation and closure activities internally at a lower cost  than 
    if  they  were  performed externally, the lower costs are used to represent management's best estimate.  In 
    addition, the discount rate used to determine the present value of reclamation and closure cost obligations 
    is the pre-tax rate that does not reflect risks for which future cash flow estimates have been adjusted.

Management's Discussion and Analysis 
 
For the Three Months Ended March 31, 2011 
 
 
1.INTRODUCTION 
 
The following provides management's discussion and analysis ("MD&A") of the financial condition and results  of 
operations  as at and for the three months ended March 31, 2011, of Greystar Resources Ltd. (the  "Company"  or 
"Greystar"). The Company adopted International Financial Reporting Standards ("IFRS") on January 1, 2011 with a 
transition  date  of January 1, 2010.  This MD&A, which has been prepared as of May 11, 2011,  supplements  and 
compliments the Company's unaudited interim consolidated financial statements and notes thereto for  the  three 
months ended March 31, 2011 and 2010, prepared in accordance with IFRS. This MD&A should be read in conjunction 
with  the  audited annual consolidated financial statements and notes thereto for the years ended December  31, 
2010  and  2009,  prepared in accordance with Canadian generally accepted accounting principles  ("GAAP").  All 
amounts in this MD&A are expressed in United States dollars unless otherwise indicated. 
 
Additional  information relevant to the Company's activities, including the Company's Annual Information  Form, 
is available on SEDAR at www.sedar.com. 
 
The Company is a precious metals exploration and development company currently working on an alternative way to 
develop its wholly owned, multi-million ounce Angostura gold-silver deposit (the "Angostura Project") in north- 
eastern Colombia. The Company is committed to developing the Angostura Project but recognizes that there  is  a 
need  to  consider additional options for its development.  Consequently, the Company intends to continue  with 
studies  into  the  feasibility  of  an alternative project, which includes an  underground  mine,  whilst  the 
uncertainty surrounding the definition of Paramo and the exclusion of mining from Paramo affects the permitting 
of  the  Company's  open  pit/heap leach project. The Company's head office is located  in  Vancouver,  British 
Columbia,  Canada  and  its  exploration and administrative office in  Colombia  is  located  in  the  city  of 
Bucaramanga.  The Angostura mineral property is located approximately 55 kilometres north-east of  Bucaramanga. 
The  Company  is  a reporting issuer in British Columbia, Alberta, Ontario and Nova Scotia and  trades  on  the 
Toronto Stock Exchange ("TSX") and on the AIM Market of the London Stock Exchange (the "AIM Market"), under the 
symbol  GSL. On May 3, 2011, the Company announced its decision to cancel the listing of its shares to  trading 
on  the  AIM Market with an effective date of June 3, 2011. The Company's shares will continue to trade on  the 
TSX. 
 
2.HIGHLIGHTS 
 
Results of Operations 
 
The  Company  adopted  IFRS on January 1, 2011, with a transition date of January 1, 2010,  and  as  a  result, 
differences  between IFRS and Canadian GAAP are explained and reconciliations provided under the  heading  "New 
Accounting Policies" in this MD&A. 
 
The  net  loss  for the three months ended March 31, 2011, was $3.6 million compared to $2.8  million  for  the 
comparative  period in 2010. Loss per share for the three months ended March 31, 2011 was $0.04 and  $0.03  for 
the comparative period in 2010. 
 
In  December 2009, the Company filed its Environmental Impact Assessment ("EIA") with the Colombian Ministry of 
Environment, Housing and Territorial Development ("MAVDT") in respect to the development of an open  pit  gold- 
silver  mine at the Company's Angostura Project in Colombia. After a series of Information and Public  Hearings 
in  2010  and 2011, the Company filed a request with MAVDT to desist from the administrative procedure  of  the 
environmental  licensing, as well as the administrative procedure of evaluation and approval of  the  Work  and 
Investment  Plan before Ingeominas. As a result, the Company has decided it will not proceed with  finalization 
of  the  feasibility  study on the open pit project at this time. The Company is committed  to  developing  the 
Angostura Project, but recognizes that there is a need to consider additional options for its development. 
 
On  April 29, 2011, the Company announced the receipt of a positive scoping stage Preliminary Assessment  under 
National  Instrument 43-101 ("Scoping Study") for an underground only operation at the Angostura  Project.  The 
Scoping  Study,  which  evaluated roasting, bio-oxidation ("BIOX") and pressure  oxidation  ("POX")  processing 
treatments for the production from Angostura underground resources, estimated that 1.9 million ounces of  gold, 
7.7  million  ounces  of silver and 228,316 pounds of copper could be produced over a 14-year  mine  life.  The 
Scoping Study is available on SEDAR at www.sedar.com. 
 
Management and Board Changes 
 
In  March,  2011,  David Heugh was appointed to the position of Chief Operating Officer  and  Frederick  Felder 
retired from his position as Executive Vice President. In April 2011, the Company announced it had agreed  with 
Amber  Capital  LP,  a  New  York-based  investment firm, which controls approximately  18%  of  the  Company's 
outstanding shares, to change the members of its board of directors and the members of its executive management 
team.   Other shareholders, holding approximately 20% of the Company's outstanding shares, advised the  Company 
that  they  supported Amber Capital LP's position. The Company appointed Mr. Juan Esteban Orduz and Mr.  Rafael 
Nieto Loaiza to the Company's board of directors.  The Company also appointed Mr. Nieto Loaiza as President  of 
the  Company and Mr. David Rovig as interim Chief Executive Officer to succeed Mr. Steve Kesler in those roles. 
It  has also been agreed that at the Company's upcoming annual general meeting, the incumbent directors,  other 
than  Messrs. Nieto Loaiza and Orduz, will not stand for re-election and the Company will nominate as directors 
certain additional individuals proposed by Amber Capital LP. 
 
 
 
3.ANGOSTURA GOLD-SILVER PROJECT UPDATE, COLOMBIA 
 
Permitting 
 
In December 2009, the Company filed its EIA with MAVDT in respect to the development of an open pit gold-silver 
mine  at  the  Company's Angostura Project in Colombia following which, there were a series of Information  and 
Public  Hearings  in  2010  and  2011. On March 18, 2011, the Company made an announcement  clarifying  certain 
comments made by the Ministry of Mines and Energy of Colombia, which could be incorrectly interpreted  to  mean 
that  the Company is fully withdrawing from the Angostura Project. The Company confirmed that that it does  not 
intend  to  withdraw  from  the Angostura Project and it intends simply to desist  from  ongoing  environmental 
licensing  to  allow for future re-filing on terms that reflect concerns. On the March 23,  2011,  the  Company 
filed a request with MAVDT to desist from the administrative procedure of the environmental licensing, as  well 
as  the  administrative procedure of evaluation and approval of the Work and Investment Plan before Ingeominas. 
As a result, the Company has decided it will not proceed with finalization of the feasibility study on the open 
pit  project  at  this time. The Company is committed to developing the Angostura Project, but recognizes  that 
there  is  a  need  to consider additional options for its development. The Company intends  to  continue  with 
studies  into  the  feasibility  of  alternatives, including an  underground  option,  whilst  the  uncertainty 
surrounding the definition of Paramo and the exclusion of mining from Paramo affects the permitting of its open 
pit/heap  leach  part  of  the project. The Company also will continue to proceed with  evaluating  the  entire 
project  while working jointly with the MAVDT as well as with the Ministry of Mines and Energy of  Colombia  in 
resolving  any outstanding issues, including how the open pit project can be modified to meet concerns  and  to 
proceed with an underground project. 
 
Underground Study 
 
On  April  29, 2011, the Company announced the receipt of a Scoping Study for an underground only operation  at 
the  Angostura  Project.  The  Technical Report entitled Mineral Resource  Estimate  and  Preliminary  Economic 
Assessment  for  Underground  Mining, Angostura Gold-Silver Project, Santander, Colombia  prepared  by  Rodrigo 
Mello,  MAusIMM,  Carlos  Guzman, MAusIMM (NCL Ingenier¡a y Construcci¢n Ltda), John  Wells,  FSAIMM,  Giovanny 
Ortiz, MAusIMM (Greystar) and dated April 25, 2011 is available on SEDAR at www.sedar.com. 
 
The  Scoping  Study,  which  evaluated roasting, BIOX and POX processing treatments  for  the  production  from 
Angostura  underground resources, estimated that 1.9 million ounces of gold, 7.7 million ounces of  silver  and 
228,316 pounds of copper could be produced over a 14-year mine life. 
 
 
 
 
Highlights of the Scoping Study include: 
 
    *All  three processing routes produce positive returns with roasting being the most economically beneficial 
     method evaluated. 
    *Average annual production for the first seven full years of 209,458 gold equivalent ("AuEq") ounces, which is 
     comprised of 197,840 ounces of gold ("Au") and 582,079 ounces of silver ("Ag"). 
    *Total cash costs of $455 per ounce over the life of mine, net of silver and copper by-product credits. 
    *Pre-tax internal rate of return ("IRR") of 21.4%(1). 
    *Estimated initial capital cost of $301.6 million. 
    *Pre-tax net present value ("NPV") of $400.2 million(1)  using a 5% discount rate. 
    *Mineable Resource ("In Stope Inferred Mineral Resource") of 2.4 million ounces of gold in 13.98 million 
tonnes 
     grading 5.35 grams per tonne ("g/t") of gold, 29.61 g/t of silver and 0.091% copper based on 3 g/t gold cut- 
off 
     grade ('COG"). 
    *Mine life of 14 years at a planned production rate of up to 4,000 tonnes per day. 
    *Potential Economic Enhancements: 
            oMineable Resource Expansion - Study does not include mineral resource estimates defined outside of 
the 
             stopes,which comprise an additional indicated mineral resource of 1.44 million ounces of gold and an 
             additional inferred mineral resource of 1.0 million ounces of gold, at 3 g/t gold COG. 
            oMineable Resource Expansion - Optimizing COG to enhance tonnage and contained ounces of gold/silver. 
            oMineral Resource Expansion - Mineralization remains open at depth with deep drilling program ongoing. 
            oImproved mine design and mineral recovery through ongoing optimization work. 
            oPotential to increase production scenario and/or enhance mine life from further exploration and 
             development of known areas of mineralization. 
 
(1) Based on a gold price of $1,170 per ounce and a silver price of $18.25 in the first two years followed by a 
life 
    of mine price of &1,015 per ounce for gold and $15,85 per ounce for silver. 
 
The Scoping Study 
 
The  Scoping Study represents an un-optimized, technically feasible design that includes the development  of  a 
mineable  resources  inventory  and a mine plan for the recovery of high-grade  veins  of  the  deposit  and  a 
preliminary  engineering design for process plant options to extract gold, silver and copper. NCL Ingenier¡a  y 
Construcci¢n  Ltda.  completed  the  mining  studies and Alquimia Conceptos  S.A.  completed  the  process  and 
infrastructure  components of the Scoping Study. NCL also developed a preliminary economic  evaluation  of  the 
project with a pre-tax cash flow analysis.

The  Scoping  Study includes only the underground portion of the Angostura gold-silver deposit,  with  a  total 
mineable  resource  comprised of In Stope Inferred Mineral Resources of 2.4 million ounces  of  gold  in  13.98 
million tonnes grading 5.35 g/t gold, 29.61 g/t silver and 0.091% copper based on 3 g/t gold COG. 
 
The Scoping Study contemplates a 4,000 tonnes per day ("tpd") underground mine and a 3,300 tpd floatation plant 
producing an average of just over 140,000 ounces of gold and just over 570,000 ounces of silver annually over a 
14  year mine life. The total mine capital cost is $220 million for the life of the mine, with $108 million for 
equipment and $49 million for development. These numbers include a 35% contingency given the preliminary nature 
of the analysis. 
 
In  all three of the processing options (Roasting, POX and BIOX), the main final product is metal Dore, with  a 
content  of 75% of gold-silver and 25% of copper. In the case of roasting, small productions of copper cathodes 
and  sulfuric acid were also accounted for and included in the economic evaluation. Pre-tax NPV at 5%  discount 
rate and IRR of the cash flows have been calculated for a gold price of $1,015 per ounce and a silver price  of 
$15.85  per ounce. Higher prices were applied to the two initial years of the plan ($1,170 per ounce  for  gold 
and $18.25 per ounce for silver). 
 
All  the options show positive results. The option of Roasting shows better NPV and slightly lower IRR compared 
to the POX option due to the contribution of copper cathodes and sulfuric acid sales. Without that contribution 
this option results in an NPV of $340 million with a 17.8% IRR. 
 
Project  sensitivity analysis indicates that the Project NPV is more sensitive to feed grade  and  metal  price 
followed by operating costs and then capital costs. 
 
Mine Design and Processing 
 
Different mining methods were analysed for the underground exploitation of the Angostura deposit. Based on  the 
rock   conditions  presented,  a  geotechnical  assessment  was  provided  by  consultants  AKL   S.A.,   whose 
recommendations for mining methods were: 
 
    *Veins with less than 5 m width = Bench and Fill Stoping 
    *Veins within 5 m and 20 m width = VCR (Vertical Crater Retreat) 
    *Veins within 20 m and 40 m width = Blast Hole Open Stoping 
 
The  processing operation was designed for a nominal throughput of 3,288 tpd with an average head grade of  5.5 
g/t gold, 18 g/t silver per tonne and 0.077% copper. According to mining plan, the ore type composition is: 75% 
sulfide; 15% transition and 10% oxide. 
 
The Mine layout was designed considering the following restrictions and criteria: 
 
    *Avoid surface accesses and roads above 3,000 meters above sea level. 
    *Main transport levels should connect the different sectors of production. 
    *Portals for access to the main transport levels located below 3,000 meters above sea level. 
    *If possible, use accesses from surface avoiding development of long internal ramps. 
    *Ore passes will take the ore to the transport level, and ventilation shafts will provide fresh air for every 
     ramp created. The ventilation shafts will be equipped with fans (range between 200 to 300 thousand cfm) that 
     have been sized according to the requirements of the mine. 
 
Mineable Mineral Resources ("In Stope Inferred Mineral Resources") 
 
In  the  preliminary underground study, underground mining potential was restricted by the terms  of  reference 
resulting  in a COG of 3.0 g/t gold. The mineral resource estimate is as of March 18, 2011, and includes  drill 
and  assay data up to July 2010. A gold price of $850 per ounce was utilized for the COG calculation.  Drilling 
results reported subsequent to this period will be incorporated into future resource updates. 
 
In  Stope mineral resource estimates consider dilution and the mineral resource estimates were determined  from 
the selected veins by generating a contour at 3.0 g/t gold COG. These contours were created from plan views  at 
20  metres.  Stopes  were  created from 20 meter level contours. These polygons were  tied  between  levels  to 
delineate  the  corresponding solids representing the stopes. A minimum width of 2 meters was applied  for  the 
construction  of the solids. Given the separation of the levels and the width of the veins, the delineation  of 
the stopes does not accurately follow the limits of the high grade veins, incorporating dilution to the content 
of  the  generated solids. For this reason, no additional dilution factors have been applied to the calculation 
of the mineable resources 
 
The terms of reference are detailed below.

The  mining method selected as most suitable for the preliminary economic assessment was bench and fill because 
of the narrow width of veins.

The  mineral  resources  in  this MD&A were estimated using the Canadian Institute of  Mining,  Metallurgy  and 
Petroleum  (CIM), Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by  the  CIM 
Standing Committee on Reserve Definitions. 
 
The  mineral resource estimate and the mineable in stope mineral resource estimate are based on 306,915  metres 
of  drill  core from 936 drill holes. Mineral resources that are not mineral reserves do not have  demonstrated 
economic viability.  The estimate of mineral resources may be materially affected by environmental, permitting, 
legal, title, taxation, sociopolitical, marketing, or other relevant issues. The quantity and grade of reported 
Inferred  resources in this estimation are uncertain in nature and there has been insufficient  exploration  to 
define  these  Inferred resources as an indicated or measured mineral resource and it is uncertain  if  further 
exploration will result in upgrading them to an Indicated or Measured mineral resource category. 
 
The  Scoping  Study  is preliminary in nature and includes inferred mineral resources that are  considered  too 
speculative  geologically to have the economic considerations applied to them that  would  enable  them  to  be 
categorized  as mineral reserves, and there is no certainty that the preliminary assessment will  be  realized. 
Additional drilling will be required and is planned to better categorize these mineral resources. 
 
Moving Forward 
 
Based  upon  the  results of this Scoping Study, the Company plans to proceed with follow-up diamond  drilling, 
engineering,  metallurgy and other work in order to develop a Preliminary Feasibility Study for an  underground 
only  operation.  A diamond drilling program is underway to expand the current underground resource.  Trade-off 
studies  will include different processing options and mining schedules. The Company will continue with further 
metallurgical testing to optimize process parameters and project economics. 
 
Qualified Persons 
 
The  Scoping  Study  is  based on a NI 43-101 compliant mineral resource estimate  reviewed  by  Rodrigo  Mello 
(MAusIMM), Independent Consulting Geologist. 
 
The  following  are the Qualified Persons as defined under National Instrument 43-101 who are  responsible  for

Company's  Exploration Manager, was responsible for the preparation of the geology, exploration and  geological 
model.   The  expert,  Americo Delgado, the Company's Superintendent of Metallurgy,  was  responsible  for  the 
metallurgical  testwork program and the review of the process plant design. All of the above Qualified  Persons 
and experts are independent of the Company with the exception of Mr. Ortiz and Mr. Delgado. 
 
Exploration 
 
In  December  2009, the Company initiated an exploration drill program to investigate the mineral potential  of 
the  La Plata mineral property, over which the Company has completed its 100% working interest acquisition,  in 
the  La  Baja  Valley, located southwest of the Angostura deposit. The Company continued with  its  program  of 
exploring the potential of high grade mineralization at the Angostura gold-silver deposit. Evaluation continued 
at  the  near surface oxide gold and deeper sulphide mineralization discovered in 2008 at the Mongora  prospect 
located 3 km south of the main Angostura deposit. 
 
Los Laches Drill Program 
 
 
The  Company announced additional assay results from the targeted drill program at the Los Laches/El Pozo  area 
of  the  Angostura  gold-silver  deposit.  The new drill results from the Los Laches  Area,  where  geology  is 
structurally  complex, continue to provide positive results showing the potential of high grade  mineralization 
at depth below the envisioned Preliminary Feasibility Study open pit. 
 
Cristo Rey 
 
During  2010,  3,778 meters of core were drilled at Cristo Rey to test higher grade mineralized  structures  at 
depth  and  along  strike. The latest results from diamond drilling in the Cristo Rey  area,  which  marks  the 
current northern limit of the Angostura deposit, included 189.5 g/t gold and 701 g/t silver over 1.5 meters  in 
hole CR10-05, 6.89 g/t gold and 85.4 g/t silver over 1.6 meters in hole CR10-04 and 12.45 g/t gold and 96.7 g/t 
silver over 1 meter in hole CR10-02. These significant intercepts confirm the presence of mineralization  along 
strike  and down dip in the northern limit of proposed Angostura pit. Mineralization in the Cristo Rey area  is 
similar  in  style  to  the  Veta  de Barro area immediately to the south where higher  grade  structures  have 
considerable  strike  extent and, although relatively narrow, the structures have very  interesting  high  gold 
grade contents. 
 
Angostura High-Grade Veins Drill Program 
 
 
The  Company has started a drill program in 2011 with the objective of improving the category of the  resources 
inside  the  veins  and  to define the continuity of the veins in strike and depth of the  Angostura  ore  body 
(including the Cristo Rey and Los Laches/El Pozo areas). 
 
Mongora Drill Program 
 
The Mongora prospect is defined by a large, 500 meter by 300 meter gold-in-soil anomaly. Core drilling to March 
2011 consists of 58 drill holes with a total of 20,276 meters, the majority of which have intercepted anomalous 
gold  grades.   Similar to the Angostura deposit, the Mongora prospect hosts higher-grade  gold  mineralization 
including  116 grams of gold per tonne over 2.0 meters, 22.2 grams of gold per tonne over 2.0 meters and  12.35 
grams  of  gold  per  tonne  over  1.6  meters within broader zones of  lower-grade  gold  mineralization.  The 
mineralization contained in the oxidized and transitional rock at the Mongora area could be very important  and 
the Company is continuing to evaluate the prospect, as it may potentially provide additional resources. 
 
La Plata 
 
La  Plata  is located in the California mining district of Colombia. La Plata comprises 78 hectares of  mineral 
rights contiguous on the majority of its borders with existing Greystar holdings. 
 
The La Plata property lies within a mineralized belt related to the northeast-southwest trending La Baja Fault, 
which  has given rise to a number of mineralized occurrences where gold and silver mineralization is associated 
with  flexures along the main fault. This mineralization, which has traditionally been mined by local artisanal 
miners, is now the focus of more modern exploration methods. 
 
Exploration carried out by the Company since 2009 identified vein and stock work mineralization associated with 
strong  alteration hosted in a dacite-porphyry system. Drilling, comprising 18 drill holes and 7,162 meters  as 
of  March  2011, has intersected anomalous gold and silver grades, and additional work is in process to  define 
the geometry of the mineralization. Rock samples from mine tunnels on site returned gold assays ranging from no 
significant gold up to 9.66 grams per ton gold and silver assays ranging from no significant silver up to  94.3 
grams per tonne silver.  At surface, the mineralized structures have returned grab sample values as high as 9.3 
g/t gold, 2,030 g/t silver, 2% copper, 736 parts per million ("ppm") molybdenum, 0.4% lead and 1% zinc. 
 
New Areas of Exploration outside of the Angostura Project Area 
 
Greystar  has applied for mineral property rights over 80,000 hectares in other jurisdictions around  Colombia, 
in  the  departments of Nari¤o, Cauca, Tolima, Caldas, Santander, Norte de Santander and Cesar  with  only  one 
having  been granted by Ingeominas to date. Ingeominas is evaluating the other applications to define the  free 
areas  to  be  granted.   Prospecting activities are being carried out to identify other mineral  potential  in 
Colombia. 
 
The  information under the heading "Exploration" has been reviewed and approved by Giovanny Ortiz, MAusIMM (the 
Company's Exploration Manager), a "qualified person" as that term is defined in National Instrument 43-101  and

Three months ended March 31, 2011 
 
Total  exploration  expenditures were $5.2 million for the three months ended March 31, 2011,  compared  to  $3 
million  for  the  three  months ended March 31, 2010.  The increase of $2.2 million  was  the  result  of  the 
following: 
 
    * Exploration costs were higher for the three months ended March 31, 2011, due to the increase in meters 
drilled 
      and drilling costs at the Angostura, Los Laches, Mongora and La Plata properties. These drilling 
expenditures 
      totalled $1.7 million during the three months ended March 31, 2011, compared to costs of $1.1 million in the 
      comparative period of 2010. 
 
    * General  and  administrative expense for the Angostura Project in Colombia (included in other  exploration 
      expense of $4.2 million) was $2.1 million for the three months ended March 31, 2011, compared to costs of $1 
      million for the comparative period in 2010 due to increases in additional personnel, consultants and 
activities 
      relating to public hearing as the Company anticipated going into development. 
 
      General  and  administrative expenses at the corporate office increased by approximately $0.9 million  for 
the 
      three  months  ended  March 31, 2011, compared to the three months ended March 31, 2010.  The  increase  was 
a 
      result of the following: 
 
    * Management and consulting fees were up $447,000 in 2011 compared to 2010, due primarily to the engagement of 
      consultants for finance advisory services, and corporate reorganization consulting services. 
 
    * Audit, legal and other professional fees were up $149,000 in 2011 compared to 2010, due primarily to 
      additional accounting assistance costs and increased legal costs. 
 
    * Travel costs were up by $136,000 in 2011 compared to 2010, due primarily to increase travel by corporate 
staff 
      resulting from increased activities in the Public Hearing process, financing, recruitment and project site 
      visits. 
 
    * Salaries and benefits were up $104,000 in 2011 compared to 2010, due primarily to the hiring of additional 
      senior corporate staff after the first quarter of 2010. 
 
    * There  has  been  a  general trend for increased general and administrative costs  on  a  quarterly  basis 
      attributable to increased activities and staffing as the Company anticipated moving into development. 
 
There was a $2.9 million gain in the fair value of warrants for the three months ended March 31, 2011, compared 
to  a  gain of $136,000 for the comparative period in 2010, primarily because the market value of the Company's 
common shares, on which the fair value of the warrants are based, declined in 2011 compared to 2010. 
 
The Company had a foreign exchange gain of $2.1 million for the three months ended March 31, 2011, compared  to 
$2.6 million for the three months ended March 31, 2010, primarily due to the large cash held in Canadian funds, 
which  appreciated against the U.S. dollar by approximately 2.3% during the three months ended March  31,  2011 
and 3% in the comparative 2010 period.

Notes and Factors Affecting Comparability of Quarters: 
 
     1.  The Company is a precious metals exploration and development company and has no operating revenue. 
Interest 
         is from funds invested. The amount of interest earned is a function of the amount of funds invested and 
         interest rates. Interest rates on term deposits dropped significantly in 2009 and remained low during 
         2010 and 2011. This, however, was offset by the significantly increased levels of cash, which contributed 
         to  increasing level of quarterly interest income in 2010 and 2011. 
 
     2.  Share-based compensation costs are a non-cash expense and represent the amortization of the estimated 
fair 
         value  of  stock options granted determined using the Black-Scholes option pricing model.  Share-based 
         compensation varies depending on the amount and fair value of the stock options granted. 
 
     3.  The increase in exploration expenditures starting in the second half of 2009 is primarily due to efforts 
         being placed to prepare the feasibility study.  Engineering costs for the feasibility study decreased 
         during the first quarter of 2011 when it was nearing completion. 
 
     4.  There  has  been  a  general trend for increased general and administrative costs on a  quarterly  basis 
         attributable to increased activities and staffing as the Company anticipated moving into development. 
 
6.LIQUIDITY AND CAPITAL RESOURCES 
 
Statement of Cash Flow Information 
 
At  March 31, 2011, cash and cash equivalents were $91.1 million, down from $98.9 million at December 31, 2010. 
The  decrease  in  cash and cash equivalents is primarily attributed to the use of cash in operations  with  no 
significant  cash  inflow  compared to the receipt of gross proceeds of $46.1  million  from  the  exercise  of 
warrants in the first quarter of 2010. 
 
The  Company's  cash  resources  are  invested in short term financial instruments  issued  by  major  Canadian 
chartered banks. These instruments mature at various dates over the current operating period. The Company  does 
not  invest  in  asset-backed commercial paper. Cash used in operations including changes in  non-cash  working 
capital  was  $7.2  million  for  the  three months ended March 31, 2011, compared  to  $1.2  million  for  the 
comparative  period  in  2010.  For  the three months ended March 31, 2011,  exploration-related  expenditures, 
including feasibility study costs, were $5.2 million and represent the major use of funds for the period. 
 
At  March  31,  2011,  the  Company had working capital of $81.3 million, but had not yet  achieved  profitable 
operations and expects to incur further losses in the development of its business.  For the three months  ended 
March  31,  2011, the Company reported a net loss of $3.6 million and as at March 31, 2011, had an  accumulated 
deficit  of  $152.3 million.  The ability of the Company to continue as a going concern is dependent  upon  the 
Company's  ability  to  arrange additional funds to complete the development of its property  and  upon  future 
profitable operations. 
 
There  is no material variance between the use of proceeds as stated in the Company's September 22, 2009, short 
form prospectus relating to its public offering and the actual application of those funds. 
 
Management  of  the Company believes that the current level of funds is expected to be sufficient  to  pay  for 
committed costs over the next 12 months. Management continues to explore alternative financing sources  in  the 
form  of equity, debt or a combination thereof; however, the current economic uncertainty and financial  market 
volatility make it difficult to predict success.  Risk factors potentially influencing the Company's ability to 
raise  equity or debt financing include: the outcome of the feasibility studies for an underground mine at  the 
Angostura  Project,  mineral  prices, the political risk of operating in a foreign country  including,  without 
limitation,  risks  relating  to permitting, and the buoyancy of the credit and  equity  markets.  For  a  more 
detailed  list of risk factors, refer to the Company's Annual Information Form for the year ended December  31, 
2010, which is filed on SEDAR. 
 
Due to the current low interest rate environment, interest income is not expected to be a significant source of 
income  or cash flow.  Management intends to monitor spending and assess results on an ongoing basis  and  will 
make appropriate changes as required. 
 
Commitments 
 
The Company's commitments related to its mineral property acquisitions are discussed below. 
 
(a)Mineral Property Commitments 
 
    The Company's mineral properties comprise surface rights, mining titles, exploration licenses, exploitation 
    permits and concession contracts that provide for gold, silver and other precious metals exploitation in an 
    area  located  in the Municipality of California, Santander, Colombia, collectively known as  the  Colombia 
    Properties.  The  licenses, permits and contracts expire at various dates ranging from  2020  to  2038  and 
    generally can be renewed for an additional 10, 20 or 30 years depending on the applicable mining code. 
 
    Certain  portions of the Colombia Properties are subject to royalties ranging from 5% to 10% of net profits 
    after  certain  additional  deductions. In addition, pursuant to the laws of Colombia,  the  Government  of 
    Colombia  currently receives royalties on gold and silver production equal to 4% of 80% of  the  production 
    value, which is calculated using the average gold and silver prices published by the London Metal Exchange. 
 
    In  order  to maintain the Company's mineral properties in good standing, the Company is required  to  make 
    certain annual fee payments based on the number of hectares and a Colombian wage factor that fluctuates  on 
    an  annual basis.  As at March 31, 2011, the required annual fee payments related to the Company's  mineral 
    properties totaled approximately $624,000 (2010 - $634,000). 
 
(b)Other Commitments 
 
    The following is a schedule of the Company's other commitments as at March 31, 2011: 
 
                                                              As of March 31, 
                                               2012        2013       2014       2015       2016     2017 and 
                                                                                                   Thereafter 
Consulting & contract Services    (a)       $ 2,130,049  $ 106,875 $       -  $      -   $       -  $       - 
 
Office operating leases           (b)           232,503    129,234    21,367    12,815       8,998          - 
                                            $ 2,362,552  $ 236,109 $  21,367  $ 12,815   $   8,998          - 
 
(a) Relates to various outsourced professional services 
(b) Primarily relates to operating leases for office premises 
 
Various commitments have been recorded as a result of the changes in management during March and April 2011. As 
at  March  31,  2011, the Company accrued $232,223 as termination payments. As of April 2011, the  Company  has 
committed $1,649,593 as termination payments. These termination payments will be paid over a period of  one  to 
six months commencing in April 2011. 
 
The  Company is from time to time involved in various claims, legal proceedings and complaints arising  in  the 
ordinary  course of business. The Company does not believe that adverse decisions in any pending or  threatened 
proceedings related to any matter, or any amount which it may be required to pay by reason thereof, will have a 
material effect on the financial condition or future results of operations of the Company. 
 
 
7.FINANCIAL INSTRUMENTS 
 
The  Company's  financial instruments are exposed to certain financial risks, including currency  risk,  credit 
risk, liquidity risk, interest risk and price risk. 
 
   (a)Currency risk 
 
    The  Company  is exposed to the financial risk related to the fluctuation of foreign exchange  rates.   The 
    Company  maintains  a significant portion of its investments in Canadian dollars. The Company  operates  in 
    Canada  and Colombia and a large portion of its expenses are incurred in Colombian pesos and U.S.  dollars. 
    A  significant change in the currency exchange rates between the U.S. dollar relative to the Colombian peso 
    and Canadian dollar could have an effect on the Company's results of operations, financial position or cash 
    flows.  The Company has not hedged its exposure to currency fluctuations. 
 
    The  Company's exposure to the Colombian peso, expressed in U.S. dollars and Colombian pesos, on  financial 
    instruments is as follows: 
 
                                      March 31, 2011                            December 31, 2010 
 
                                        US$       Colombian Peso                    US$       Colombian Peso 
Cash and cash equivalents    $      386,596          726,595,817         $       94,032          179,975,804 
Trade and other receivables         649,812        1,221,301,225                529,412        1,013,284,852 
Trade and other payables          2,344,860        4,407,094,745              2,421,976        4,635,613,156 
                             $    3,381,268        6,354,991,787         $    3,045,420        5,828,873,812 
 
    As at March 31, 2011, with other variables unchanged, a 10% depreciation or appreciation of the U.S. dollar 
    against  the Colombian peso would change the values of the Colombian peso denominated financial instruments 
    and would affect the consolidated statement of operations and comprehensive loss by approximately $338,000. 
 
    The  Company's  exposure to the Colombia peso on quarterly exploration expenditures  throughout  the  three 
    months ended March 31, 2011 was $4.8 million. A 10% depreciation or appreciation of the U.S. dollar against 
    the  Colombian  peso  would  affect  the consolidated statement of operations  and  comprehensive  loss  by 
    approximately $484,000. 
 
    The  Company's exposure to the Canadian dollar, expressed in U.S dollars and Canadian dollars, on financial 
    instruments is as follows: 
 
 
 
 
 
 
                                     March 31, 2011                            December 31, 2010 
 
                                        US$               CDN$                      US$                  CDN$ 
Cash and cash equivalents    $   90,490,815     $   87,938,974           $   97,022,814        $   96,498,890 
Trade and other receivables         240,405            233,626                  249,539               248,192 
Trade and other payables          2,129,326          2,069,279                3,929,595             3,791,313 
                             $   92,860,546     $   90,241,879            $ 101,201,948        $  100,538,395 
 
    As at March 31, 2011, with other variables unchanged, a 10% depreciation or appreciation of the U.S. dollar 
    against  the  Canadian  dollar  would  change  the values of  the  Canadian  dollar  denominated  financial 
    instruments  and  would  affect  the  consolidated  statement  of  operations  and  comprehensive  loss  by 
    approximately $9.3 million. 
 
    The  Company's exposure to the Canadian dollar on quarterly exploration expenditures throughout  the  three 
    months ended March 31, 2011 was $516,000. A 10% depreciation or appreciation of the U.S. dollar against the 
    Canadian  dollar  would  affect  the  consolidated  statement  of  operations  and  comprehensive  loss  by 
    approximately $52,000. 
 
    (b) Credit risk 
 
    Credit risk is the risk of an unexpected loss if a third party to a financial instrument fails to meet  its 
    contractual  obligations. The Company manages its credit risk through its counterparty ratings  and  credit 
    limits. 
 
    The  Company's  cash  and  cash  equivalents and short term investments are  held  through  large  Canadian 
    financial  institutions. Short-term investments are composed of financial instruments  issued  by  Canadian 
    banks  and  companies  with high investment-grade ratings.  These instruments mature and  are  cashable  at 
    various dates over the current operating period. Amounts receivable primarily consists of Harmonized  Sales 
    Tax receivable with expected payment from the Canadian government. 
 
    The  total  cash and cash equivalents and accounts receivable represent the maximum credit  exposure.   The 
    Company  limits  its  credit  risk exposure by holding bank accounts and any short  term  investments  with 
    reputable banks with high credit ratings. 
 
    (c) Liquidity risk 
 
    The  Company manages liquidity risk by maintaining adequate cash balances in order to meet short  and  long 
    term  business requirements.  The Company believes that these sources will be sufficient to cover its  cash 
    requirements for the upcoming year.  The Company's cash is invested in liquid investments with good quality 
    financial institutions and is not invested in any asset backed commercial paper. 
 
    As at March 31, 2011, the Company's liabilities have contractual maturities as summarized below: 
 
                                                                                                         Less than 
                                                                                            Total           1 year 
     Trade and other payables                                                         $ 4,474,187      $ 4,474,187 
     Amounts payable on exploration and evaluation asset acquisition                    1,140,516        1,140,516 
                                                                                      $ 5,614,703      $ 5,614,703 
 
    (d) Interest rate risk 
 
    Interest  rate  risk  is the risk that the fair value or future cash flows of a financial  instrument  will 
    fluctuate because of changes in market interest rates.  The Company's cash in bank accounts and investments 
    earn  interest  income at variable rates.  The Company's future interest income is exposed  to  changes  in 
    short-term rates. Assuming cash remains constant, an increase or decrease in the annual interest rate of 1% 
    would result in a corresponding increase or decrease of annual interest income by $911,000. 
 
    (e) Fair value of financial instruments 
 
    The  fair values of amounts receivable and accounts payable and accrued liabilities       approximate their 
    carrying values due to the short-term nature of these instruments. The fair value of the amounts payable on 
    mineral  property  acquisitions approximates their carrying value as there was no material  change  to  the 
    discount rate used to calculate the fair value since initial recognition. 
 
    There are three levels of the fair value hierarchy that prioritize the inputs to valuation techniques  used 
    to  measure  fair  value,  with Level 1 inputs having the highest priority. The levels  and  the  valuation 
    techniques used to value the Company's financial assets and liabilities are described below: 
 
             (i)Level 1 - Quoted Prices in Active Markets for Identical Assets 
 
                 Unadjusted  quoted  prices in active markets that are accessible at the measurement  date  for 
                 identical, unrestricted assets or liabilities. 
 
                 Cash  equivalents, including demand deposits and money market instruments,  are  valued  using 
                 quoted  market prices. Marketable equity securities are valued using quoted market  prices  in 
                 active  markets, obtained from securities exchanges. Accordingly, these items are included  in 
                 Level 1 of the fair value hierarchy. 
 
            (ii)Level 2 - Significant Other Observable Inputs 
 
                 Quoted  prices in markets that are not active, quoted prices for similar assets or liabilities 
                 in  active  markets,  or  inputs  that  are observable, either  directly  or  indirectly,  for 
                 substantially the full term of the asset or liability. 
 
           (iii)Level 3 - Significant Unobservable Inputs 
 
                Unobservable (supported by little or no market activity) prices. 
 
    The  following table illustrates the classification of the Company's financial instruments recorded at fair 
    value within the fair value hierarchy as at March 31, 2011.

9.CRITICAL ACCOUNTING ESTIMATES 
 
Exploration and Evaluation Assets 
 
The  application  of  the  Company's accounting policy for and determination on recoverability  of  capitalized 
exploration  and evaluation expenditure requires judgement in determining whether future economic benefits  are 
likely, which may be based on assumptions about future events or circumstances.  Estimates and assumptions made 
may  change  if  new information becomes available.  If, after expenditure is capitalized, information  becomes 
available suggesting that the recovery of expenditure is unlikely, the amount capitalized is recognized in loss 
in  the  period  that  the  new  information becomes available. As at March 31, 2011,  amounts  capitalized  to 
exploration and evaluation assets total $18.1 million. 
 
Amounts Payable on Exploration and Evaluation Asset Acquisition 
 
Included  in the Company's balance sheet is the fair value of the amounts payable on exploration and evaluation 
asset  acquisition. The fair value of the amounts payable on exploration and evaluation asset  acquisition  was 
determined  by  discounting the stream of future cash payments at the estimated prevailing  pre-tax  risk  free 
interest  rate.  Changes  in  assumptions can materially affect the fair value  estimate,  and  therefore,  the 
existing models do not necessarily provide a reliable single measure of the fair value. 
 
Site Restoration Provision 
 
The  Company assesses its site restoration provision annually.  Significant estimates and assumptions are  made 
in  determining  the  site restoration provision as there are numerous factors that will  affect  the  ultimate 
liability  payable.   These  factors include estimates of the extent and costs  of  rehabilitation  activities, 
technological  changes, regulatory changes, cost increases, and changes in discount rates.  Those uncertainties 
may  result  in future actual expenditure differing from the amount currently provided.  The provision  at  the 
date  of the statement of financial position represents management's best estimate of the present value of  the 
future  site restoration costs required.  Changes to estimated future costs are recognized in the statement  of 
financial  position  by  adjusting  the site restoration asset and liability.  To  the  extent  that  the  site 
restoration  provision was created due to exploration activities, the amount capitalized is reduced immediately 
by a charge to exploration expenses for the same amount. 
 
Income taxes 
 
Judgement  is required in determining whether deferred tax assets are recognized in the statement of  financial 
position.   Deferred  tax  assets, including those arising from unutilized tax losses,  require  management  to 
assess  the  likelihood that the Company will generate taxable earnings in future periods, in order to  utilize 
recognized  deferred  tax  assets.  Estimates of future taxable income are based on forecast  cash  flows  from 
operations and the application of existing tax laws in each jurisdiction.  To the extent that future cash flows 
and  taxable income differ significantly from estimates, the ability of the Company to realize the net deferred 
tax  assets recorded at the date of the statement of financial position could be impacted. Additionally, future 
changes  in tax laws in the jurisdictions in which the Company operates could limit the ability of the  Company 
to obtain tax deductions in future periods. 
 
Fair value of share-based compensation and warrants issued 
 
The fair value of share-based compensation and warrants issued with Canadian dollar exercise prices are subject 
to  the  limitation  of  the  Black-Scholes option pricing model that incorporates  market  data  and  involves 
uncertainty in estimates used by management in the assumptions. Because the Black-Scholes option pricing  model 
requires  the  input  of  highly subjective assumptions, including the volatility of share  price,  changes  in 
subjective input assumptions can materially affect the fair value estimate. 
 
10.FIRST TIME ADOPTION OF IFRS 
 
The  Company  adopted IFRS on January 1, 2011 with a transition date of January 1, 2010.  IFRS  1,  "First-time 
adoption  of International Financial Reporting Standards," provides guidance for the initial adoption of  IFRS. 
IFRS  1  requires retrospective application of the standards in the transition statement of financial position, 
with  all  adjustments  to  assets  and  liabilities taken to deficit unless  certain  mandatory  and  optional 
exemptions are applied. 
 
The Company has applied the following exemptions to its opening statement of financial position: 
 
(a)Business combinations 
 
    The  Company  has  elected to not apply IFRS 3 to business combinations that occurred before  the  date  of 
    transition  to  IFRS, which is an election permitted on first-time adoption of IFRS.  IFRS 3 is  applicable 
    for business combinations occurring on or after January 1, 2010. 
 
(b)Cumulative foreign currency translation differences 
 
    As  permitted by the IFRS 1 election for cumulative foreign currency translation differences,  the  Company 
    has  deemed  cumulative foreign currency translation differences for foreign operations to be zero  at  the 
    date of transition.  Any gains and losses on subsequent disposal of foreign operations will not be impacted 
    by translation differences that arose prior to the date of transition. 
 
(c)Share-based payments 
 
    Under  IFRS  1,  a first time adopter can elect not to apply IFRS 2, "Share-based Payment," to  share-based 
    payments  granted after November 7, 2001, that vested the later of (a) the date of the transition  and  (b) 
    January  1,  2005.  The  Company has elected to apply this exemption and to apply IFRS  2  only  to  awards 
    unvested at the January 1, 2010, date of transition.  IFRS has not been applied to awards that vested prior 
    to January 1, 2010. 
 
(d)Compound financial instruments 
 
    The  Company  has  elected  to  apply the exemption related to compound  financial  instruments  where  the 
    liability  component  is  no  longer outstanding at the date of transition  to  IFRS.  IAS  32,  "Financial 
    Instruments:  Presentation," requires an entity to split a compound financial instrument at inception  into 
    its  separate liability and equity components. If the liability component is no longer outstanding  at  the 
    IFRS  transition date, a first-time adopter need not separate the impact of compound financial  instruments 
    between the respective components of equity. 
 
(e)Site restoration provision 
 
    IFRS  1  allows  first  time adopters to not fully comply with the requirements of  IFRIC  1,  "Changes  in 
    Existing  Decommission, Restoration and Similar Liabilities," for such liabilities outstanding at the  IFRS 
    transition  date and instead apply a simplified method as set out in IFRS 1.  The Company  has  elected  to 
    apply  this  exemption  related  to site restoration provisions.  IFRIC 1  dealing  with  changes  in  site 
    restoration provisions will be applied on a prospective basis from the date of transition. 
 
(f)Leases 
 
    The  Company  has  elected  to apply the IFRS exemption with respect to leases. This  election  allows  the 
    Company to apply the transitional provisions of IFRIC Interpretation 4, "Determining Whether an Arrangement 
    Contains  a Lease," to determine whether an arrangement existing at the date of transition to IFRS contains 
    a lease on the basis of facts and circumstances existing at that date. 
 
(g)Borrowing costs 
 
    Borrowing  costs  related  to  the acquisition, construction or production of  qualifying  assets  must  be 
    capitalized  under  IAS  23,  "Borrowing Costs." In accordance with IFRS 1,  the  Company  has  elected  to 
    prospectively apply IAS 23 effective January 1, 2010. 
 
(h)Estimates 
 
    IFRS  1 requires that an entity's estimates under IFRS at the date of transition to IFRS must be consistent 
    with  estimates made for the same date under the entity's previous GAAP, unless there is objective evidence 
    that those estimates were in error.  The Company's IFRS estimates as of January 1, 2010 are consistent with 
    its Canadian GAAP estimates for the same date. 
 
IFRS employs a conceptual framework that is similar to Canadian GAAP; however, significant differences exist in 
certain areas of recognition, measurement and disclosure. While the adoption of IFRS has not changed the actual 
cash  flows  of the Company, the adoption has resulted in changes to the Company's reported financial  position 
and  results of operations. In order to allow financial statement users to better understand these changes, the 
Company's  Canadian GAAP opening statement of financial position at January 1, 2010, and interim statements  of 
financial  position  at March 31, 2010 and December 31, 2010, and statements of comprehensive  loss,  and  cash 
flows for the three months ended March 31, 2010, and the year ended December 31, 2010, have been reconciled  to 
IFRS and presented below, along with explanations of the resulting differences. 
 
 
The  Company's Canadian GAAP statement of financial position as at January 1, 2010, has been reconciled to IFRS 
as follows:

Explanatory notes to the IFRS reconciliations above 
 
    (i)Functional currency 
 
    Under  Canadian  GAAP  -  An entity is not explicitly required to assess the unit  of  measure  (functional 
    currency) in which it measures its own assets, liabilities, revenues and expenses.  Under Canadian GAAP, an 
    entity  applies criteria to determine only whether a foreign subsidiary's operation is integrated or  self- 
    sustaining, in which case the temporal or current methods of translation respectively, are then applied  to 
    the  subsidiary's financial statement balances and results of operations.  Under Canadian GAAP, the Company 
    prepared  its  financial  statements in Canadian dollars and its Colombian  branch  and  subsidiaries  were 
    determined to be integrated foreign operations. 
 
    Under  IFRS  - The functional currency of the reporting entity and each of its foreign operations  must  be 
    assessed  independently giving consideration to the primary economic environment in  which  each  operates. 
    IFRS  provides  guidance  in  respect  of factors to be considered in determining  an  entity's  functional 
    currency that are similar to those noted in Canadian GAAP, however unlike Canadian GAAP, IFRS distinguishes 
    between  primary and secondary factors in making such an assessment.  Based on the assessment  under  IFRS, 
    management  has determined that the functional currencies of Greystar Resources Ltd., its Colombian  branch 
    and  subsidiaries are the U.S. dollar as this is the currency of the primary economic environment in  which 
    the  Company operates.  Accordingly, the change in functional currency has been reflected in reporting  the 
    Company's financial position and results of operations under IFRS. 
 
    (ii)Change in presentation currency 
 
    The  Company  previously presented its financial statements in Canadian dollars. Under IFRS, the  Company's 
    financial  statements  are presented in U.S. dollars, the same as its functional currency.  The  change  in 
    presentation  currency results in a cumulative translation adjustment and under IFRS  1,  the  Company  has 
    elected to eliminate the cumulative translation adjustment on the IFRS transition date. 
 
    (iii)Share-based payments 
 
    Under  Canadian GAAP - The fair value of stock-based awards with graded vesting are calculated as one grant 
    and the resulting fair value is recognized on a straight-line basis over the vesting period. Forfeitures of 
    awards are recognized as they occur. 
 
    Under  IFRS - Each tranche of an award with different vesting dates is considered a separate grant for  the 
    calculation  of  fair  value, and the resulting fair value is amortized over the  estimated  lives  of  the 
    respective tranches. Forfeiture estimates are recognized in the period they are estimated, and are  revised 
    for actual forfeitures in subsequent periods. 
 
    (iv)Share purchase warrants 
 
    Under  Canadian  GAAP  -  The  Company's share purchase warrants are measured  at  fair  value  at  initial 
    recognition using the Black-Scholes option pricing model, and recorded in equity reserve with no subsequent 
    re-measurement. 
 
    Under  IFRS  -  The exercise prices of the Company's share purchase warrants that are issued in  connection 
    with  the  issuance  of  equity are denominated in Canadian dollars, which is not the Company's  functional 
    currency. As a result, the proceeds from the exercise of these warrants will vary. These warrants meet  the 
    definition  of  derivatives  under IAS 32 and are therefore, classified  as  liabilities  and  measured  at 
    financial  assets at fair value through profit or loss at grant date and the end of each reporting  period. 
    The  Company's share purchase warrants issued as compensation for mineral property acquisitions and agents' 
    commissions  for share issuances are accounted for under IFRS 2 and are classified as equity. The  adoption 
    of IFRS had no impact on these warrants. 
 
    (v)Compound financial instruments 
 
    Under  Canadian GAAP - The Company raised equity by issuing units that consisted of common shares and share 
    purchase warrants. The gross proceeds were allocated to common shares and warrants using the relative  fair 
    value method. 
 
    Under  IFRS - IAS 32 requires an entity to split a compound financial instrument at inception into separate 
    liability  and  equity components. For proceeds received from the issuance of compound  equity  instruments 
    such  as  units  comprised  of common shares and warrants, the Company allocated  the  proceeds  using  the 
    residual  method whereby the proceeds allocated to the warrants is based on their Black-Scholes fair  value 
    with the remaining proceeds allocated to common shares. 
 
    (vi)Site restoration provision 
 
    Under  Canadian  GAAP  -  The  Company uses the best estimate that a  third  party  would  charge  for  the 
    remediation  work  to measure the reclamation and closure cost obligations. The Company  uses  the  credit- 
    adjusted  pre-tax  risk-free  interest  rate  as a discount rate  to  measure  the  net  present  value  of 
    undiscounted estimated future cash flows. 
 
    Under IFRS - Under IAS 37, reclamation and closure cost obligations are measured based on management's best 
    estimate  of the expenditures required to settle the obligations as at the balance sheet date. In the  case 
    that  management intends to perform the reclamation and closure activities internally at a lower cost  than 
    if  they  were  performed externally, the lower costs are used to represent management's best estimate.  In 
    addition, the discount rate used to determine the present value of reclamation and closure cost obligations 
    is the pre-tax rate that does not reflect risks for which future cash flow estimates have been adjusted. 
 
11.OFF BALANCE SHEET ARRANGEMENTS 
 
The Company has no off-balance sheet arrangements. 
 
12.OUTSTANDING SHARE DATA 
 
The  Company  has  only  one  class of share capital, common shares without par value.  The  number  of  shares 
authorized is unlimited. The Company has issued warrants for the purchase of common shares and also has a stock 
option plan. 
 
The following are outstanding at May 11, 2011: 
 
Common shares                                                                  84,227,487 
Shares issuable on the exercise of warrants                                     3,365,686 
Shares issuable on the exercise of outstanding stock options                    6,068,055 
 
 
 
 
 
 
13.RISKS AND UNCERTAINTIES 
 
The  Company competes with other mining companies, some of which have greater financial resources and technical 
facilities,  for  the  acquisition of mineral concessions, claims and other  interests,  as  well  as  for  the 
recruitment and retention of qualified employees. 
 
The  Company  is  in  compliance  in  all  material respects with regulations  applicable  to  its  exploration 
activities.  Existing  and  possible  future environmental legislation, regulations  and  actions  could  cause 
additional expense, capital expenditures, restrictions and delays in the activities of the Company, the  extent 
of  which  cannot  be  predicted.  Before production can commence on any properties, the  Company  must  obtain 
regulatory and environmental approvals. There is no assurance that such approvals can be obtained on  a  timely 
basis  or  at all. The cost of compliance with changes in governmental regulations has the potential to  reduce 
the profitability of operations. 
 
The  Company's  mineral  property is located in Colombia. The Company is subject to  certain  risks,  including 
currency fluctuations and possible political or economic instability which may result in the impairment or loss 
of  mining  title  or other mineral rights, and mineral exploration and mining activities may  be  affected  in 
varying  degrees  by  political stability and governmental regulations relating to  the  mining  industry.  The 
acquisition  of mining title in Colombia is a very detailed and time-consuming process. In addition,  title  to 
mining rights may be disputed. 
 
The  Company has incurred losses since its inception and will not achieve profitability until such time as  the 
Angostura Project can be developed into a profitable operation.

Information Form for the year ended December 31, 2010, which can be found on SEDAR at www.sedar.com. 
 
 
14.INTERNAL CONTROL OVER FINANCIAL REPORTING 
 
Disclosure Controls and Procedures 
 
Disclosure controls and procedures are designed to provide reasonable assurance that information required to be 
disclosed by the Company under Canadian Securities laws is recorded, processed, summarized and reported  within 
the  time  periods  specified  under those laws and include controls and procedures  designed  to  ensure  such 
information  is accumulated and communicated to management, including the Chief Executive Officer  ("CEO")  and 
the Chief Financial Officer ("CFO"), to allow timely decisions regarding required disclosure. 
 
There  has  been  no change in the Company's disclosure controls and procedures during the three  months  ended 
March 31, 2011, that has materially affected or is reasonably likely to materially affect the purposes set  out 
above. 
 
Internal Controls over Financial Reporting 
 
Management  is  responsible for the establishment, maintenance and testing of adequate internal  controls  over 
financial  reporting ("ICFR") to provide reasonable assurance regarding the reliability of financial  reporting 
and the preparation of financial statements for external purposes in accordance with Canadian GAAP. 
 
The  Company's management and the Board of Directors do not expect that its disclosure controls and  procedures 
or  internal  controls over financial reporting will prevent all errors or all instances of  fraud.  A  control 
system, no matter how well designed and operated, can provide only reasonable (not absolute) assurance that the 
control system's objectives will be met. 
 
Further,  the design, maintenance and testing 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 gaps and instances of fraud have been detected. These inherent limitations  include 
the  reality  that  judgment in decision-making can be faulty, and that simple errors or  mistakes  can  occur. 
Controls  can also 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, maintenance and testing of any system of  controls  is 
based  in part upon certain assumptions about the likelihood of future events, and any control system  may  not 
succeed in achieving its stated goals under all potential future conditions. 
 
There  has  been no change in the Company's internal control over financial reporting during the  three  months 
ended March 31, 2011, that has materially affected, or is reasonably likely to materially affect, the Company's 
internal controls over financial reporting. 
 
15.FORWARD LOOKING STATEMENTS 
 
Certain  statements included or incorporated by reference in this MD&A, including information as to the  future 
financial or operating performance of the Company, and its projects, constitute forward-looking statements. The 
words  "believe",  "expect",  "anticipate", "contemplate", "target", "plan", "intends",  "continue",  "budget", 
"estimate",  "may",  "will", "schedule" and similar expressions identify forward-looking  statements.  Forward- 
looking  statements  include,  among other things, statements regarding the estimation  of  mineral  resources, 
estimated annual production, estimated pre-tax internal rate of return, estimated capital cost, estimated  pre- 
tax  net  present  value and estimated mine life relating to an underground option at the  Company's  Angostura 
Project  and  the  future  price of gold and silver. Forward-looking statements are  based  upon  a  number  of 
estimates  and assumptions made by the Company in light of its experience and perception of historical  trends, 
current  conditions  and  expected future developments, as well as other factors  that  Greystar  believes  are 
appropriate  in  the  circumstances. While these estimates and assumptions are  considered  reasonable  by  the 
Company,  they  are  inherently subject to significant business, economic, competitive,  political  and  social 
uncertainties  and  contingencies. Many factors could cause the Company's actual results to  differ  materially 
from  those expressed or implied in any forward-looking statements made by, or on behalf of, the Company.  Such 
factors  include, among other things, risks relating to permitting, risks relating to the Company's ability  to 
obtain  adequate  financing for the development of the Angostura Project, conclusions of economic  evaluations; 
changes  in  project  parameters as plans continue to be refined; future prices of gold  and  silver,  possible 
variations  in  ore  reserves, grade or recovery rates; risks related to fluctuations in the  currency  market, 
risks  related to the business being subject to environmental laws and regulations which may increase costs  of 
doing  business and restrict the Company's operations; risks relating to title disputes; risks relating to  all 
the  Company's properties being located in Colombia, including political, economic and regulatory  instability, 
accidents,  labour disputes and other risks of the mining industry; delays in obtaining governmental  approvals 
or  financing  or  in the completion of development or construction activities. These factors and  others  that 
could  affect Greystar's forward-looking statements are discussed in greater detail in the section headed "Risk 
Factors"  in the Company's Annual Information Form for the year ended December 31, 2010, which can be found  on 
SEDAR  at  www.sedar.com. Investors are cautioned that forward-looking statements are not guarantees of  future 
performance  and, accordingly, investors are cautioned not to put undue reliance on forward-looking  statements 
due to the inherent uncertainty therein. Forward-looking statements are made as of the date of this MD&A, or in 
the  case  of  documents  incorporated by reference herein, as of the date of such document,  and  the  Company 
disclaims  any intent or obligation to update publicly such forward-looking statements, whether as a result  of 
new information, future events or results or otherwise, other than as required by applicable securities laws.
