INDEPENDENT AUDITORS' REPORT TO THE SHAREHOLDERS 
 
We have audited the accompanying consolidated financial statements of Greystar Resources Ltd., which comprise the 
consolidated balance sheets as at December 31, 2010 and 2009, the consolidated statements of operations, 
comprehensive loss and deficit, shareholders' equity and cash flows for the years then ended, and notes, 
comprising a summary of significant accounting policies and other explanatory information. 
 
Management's Responsibility for the Consolidated Financial Statements 
 
Management is responsible for the preparation and fair presentation of these consolidated financial statements in 
accordance with Canadian generally accepted accounting principles, and for such internal control as management 
determines is necessary to enable the preparation of consolidated financial statements that are free from material 
misstatement, whether due to fraud or error. 
 
Auditors' Responsibility 
 
Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We 
conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require 
that we comply with ethical requirements and plan and perform the audit to obtain reasonable assurance about 
whether the consolidated financial statements are free from material misstatement. 
 
An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the 
consolidated financial statements. The procedures selected depend on our judgment, including the assessment of the 
risks of material misstatement of the consolidated financial statements, whether due to fraud or error. In making 
those risk assessments, we consider internal control relevant to the entity's preparation and fair presentation of 
the consolidated financial statements in order to design audit procedures that are appropriate in the 
circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal 
control. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness 
of accounting estimates made by management, as well as evaluating the overall presentation of the consolidated 
financial statements. 
 
We believe that the audit evidence we have obtained in our audits is sufficient and appropriate to provide a basis 
for our audit opinion. 
 
Opinion 
 
In our opinion, the consolidated financial statements present fairly, in all material respects, the financial 
position of Greystar Resources Ltd. as at December 31, 2010 and 2009, and the results of its operations and its 
cash flows for the years then ended in accordance with Canadian generally accepted accounting principles.

GREYSTAR RESOURCES LTD. 
 
Notes to Consolidated Financial Statements 
(Expressed in Canadian dollars) 
For the year ended December 31, 2010 
 
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 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 December 31, 2010, the Company had working capital of $90,774,567 but had not yet achieved profitable 
operations and expects to incur further losses in the development of its business.  For the year ended December 
31, 2010, the Company reported a net loss of $35,941,803 and as at December 31, 2010, had an accumulated deficit 
of $173,164,292. 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, including obtaining the necessary permits 
and other regulatory approvals, and upon future profitable operations. 
 
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. On April 20, 2010, the MAVDT requested a new EIA to be 
filed that conforms to a new regulation which calls for an adjustment of the occupied area outside of 'Paramo.' 
MAVDT's request would have required the Angostura project to be completely redesigned and would have severely 
impacted the project schedule and may have had a material effect on its economic viability. On April 29, 2010, the 
Company filed an appeal of the notification from MAVDT. On May 28, 2010, the Company received a letter from MAVDT 
that reinstated the Company's EIA as filed. MAVDT will move forward with a review of the Company's EIA as 
originally filed. On July 15, 2010, MAVDT issued a notice to the Company that, at the request of third parties, 
Information Meetings for local communities that were being planned by the Company are to be incorporated into a 
public hearing process. The Company held two Informational Hearings on November 3 and 4, 2010, and the Public 
Hearing on November 21, 2010, to hear the views and opinions of certain interested parties on the environmental 
impact of the Angostura project. These Information and Public Hearings are steps in the process relating to the 
decision from MAVDT on issuing an environmental permit for the Angostura project. In December 2010, MAVDT notified 
the Company that a new Information Meeting and Public Hearing for the environmental permit are to be held in 
Bucaramanga. This decision was based on the fact that certain participants opposing the project, who had 
registered to address the general public during the first hearing, were in the petitioner's view, unable to 
participate on account of alleged restrictions in the road heading to California, Santander. This exceptional 
request was intended to better allow inhabitants of the city of Bucaramanga to express their views on the project. 
The Information Meeting was held on February 17, 2011, and the Public Hearing held on March 4, 2011, but was 
terminated early and cancelled by MAVDT after 28 of the inscribed 470 statements had been heard. 
 
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" (which in this context, means to cease the Company's intention of further pursuing a 
formal petition or request for the administrative procedure for an environmental license at this time with a 
Colombian governmental entity, but without prejudice of the right and opportunity to file a new petition or 
request for administrative procedure for a mining project environmental license in the future) from ongoing 
environmental licensing to allow for future re-filing on terms that reflects concerns. On the March 23, 2011, the 
Company filed a request to desist from the administrative procedure of the environmental licensing before MAVDT. 
The Company is committed to developing the Angostura Project, but recognizes that there is a need to reconfigure 
it. 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 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. The Company has completed a 
Preliminary Economic Evaluation ("PEE") of an underground operation at the Angostura Project that targets the high 
grade resource at Angostura. The Company proposes to work rapidly to advance the next phase of study and drilling 
with an objective to increase and improve the categorization of high grade underground resources, and 
investigating the potential to extend the resource at length and depth. 
 
2. Significant accounting policies 
 
(a) Basis of presentation and consolidation 
 
These consolidated financial statements have been prepared in accordance with Canadian generally accepted 
accounting principles. They include the accounts of the Company, its controlled subsidiaries and branch operations 
in Colombia. All significant intercompany transactions and balances have been eliminated. 
 
2. Significant accounting policies (continued) 
 
(b) Comparative figures 
 
Comparative figures have been adjusted to conform to changes in presentation in these consolidated financial 
statements where required. 
 
(c) Cash and cash equivalents 
 
Cash and cash equivalents are comprised of cash on deposit with banks and highly liquid investments having 
original terms to maturity of one year or less when acquired. 
 
(d) Equipment 
 
Equipment is recorded at cost less accumulated depreciation. Depreciation is recognized in profit or loss on a 
straight-line basis over the estimated useful lives of equipment. The estimated useful lives are as follows: 
 
- Buildings               20 years 
- Field equipment         3 to 5 years 
- Office equipment        3 years 
- Transport               5 years 
 
(e) Mineral properties 
 
Exploration and development 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. Mineral property 
acquisition costs and 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 mineral properties represent acquisition costs incurred to date, less recoveries and write- 
offs, and do not reflect fair value. 
 
(f) Impairment assessment 
 
The Company performs impairment tests on its mineral properties when events or changes in circumstances indicate 
that the carrying values of these assets may not be recoverable. As of December 31, 2010, management determined 
there is no impairment or write-down of the carrying value of mineral properties. 
 
(g) Asset retirement obligations 
 
The Company recognizes statutory, contractual or other legal obligations related to the retirement of tangible 
long-lived assets when such obligations are incurred, if a reasonable estimate of fair value can be made. These 
obligations are measured initially at fair value and the resulting costs capitalized to the carrying value of the 
related asset. To the extent that the asset retirement obligation was created due to exploration activities, the 
amount capitalized is reduced immediately by a charge to exploration expenses for the same amount. To the extent 
that the asset retirement obligation was created due to development activities, the amount capitalized is 
amortized to operations over the life of the asset. In subsequent periods, the liability is adjusted for any 
changes in the amount or timing and for the discounting of the underlying future cash flows. The asset retirement 
obligation is classified as current and long-term, based on expectation of settlement. 
 
(h) 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, the Company uses the relative fair value method to allocate 
proceeds received between the common share and warrant units upon initial recognition. 
 
(i) Stock-based compensation and other stock-based payments 
 
The Company has a stock option plan that is described in note 7(c). The Company records all stock-based payments 
using the fair value method. Under the fair value method, stock based payments for employees are measured at fair 
value at the date of grant and stock- based payments to non-employees are measured at the fair value of the 
consideration received or the fair value of the equity instruments issued, whichever is more reliably measurable 
and are amortized over the vesting period. The offset to the recorded cost is to contributed surplus. 
Consideration received on the exercise of stock options is recorded as share capital and the related contributed 
surplus is transferred to share capital. 
 
(j) Income taxes 
 
The Company uses the asset and liability method of accounting for income taxes. Under this method of tax 
allocation, future income tax assets and liabilities are determined based on differences between the financial 
statement carrying values of existing assets and liabilities and their respective income tax bases (temporary 
differences), and losses carried forward. Future income tax assets and liabilities are measured using the tax 
rates expected to be in effect when the temporary differences are likely to reverse. The effect on future income 
tax assets and liabilities of a change in tax rates is included in operations in the period in which the change is 
enacted or substantively enacted. The amount of future income tax assets recognized is limited to the amount of 
the benefit that is more likely than not to be realized. 
 
(k) Loss per share 
 
Basic loss per share is calculated using the weighted average number of common shares issued and outstanding 
during the period. 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 options (note 7(d)) and warrants (note 
7(e)) on loss per share would be anti-dilutive. 
 
(l) Foreign currency translation 
 
Transactions and account balances originally stated in currencies other than Canadian dollars have been translated 
into Canadian dollars using the temporal method of foreign currency translation as follows: 
 
- Revenue and expense items at average exchange rates. 
 
- Non-monetary assets and liabilities at historical exchange rates, unless such items are carried at market value, 
in which case they are translated at the exchange rate in effect on the balance sheet date. 
 
- Monetary assets and liabilities at the exchange rate in effect at the balance sheet date. 
 
Exchange gains and losses are recorded in the statement of operations in the period in which they occur. 
 
(m) Financial instruments 
 
All financial instruments are classified into one of five categories: held-for-trading, held-to- maturity 
investments, loans and receivables, available-for-sale financial assets or other financial liabilities. All 
financial instruments and derivatives are measured in the balance sheet at fair value except for loans and 
receivables, held-to-maturity investments and other financial liabilities which are measured at amortized cost. 
Subsequent measurement and changes in fair value will depend on their initial classification as follows: (1) held- 
for-trading financial assets are measured at fair value and changes in fair value are recognized in the statement 
of operations; (2) available-for-sale financial instruments are measured at fair value with changes in fair value 
recorded in other comprehensive income until the instrument is derecognized or impaired; and (3) all derivative 
instruments, including embedded derivatives, are recorded in the balance sheet at fair value unless they qualify 
for the normal sale normal purchase exemption and changes in their fair value are recorded in income unless cash 
flow hedge accounting is used, in which case changes in fair value are recorded in other comprehensive income. 
 
The Company has classified its cash and cash equivalents as held-for-trading and thus, measured at fair value. 
Accounts receivables are classified as loans and receivables and thus, measured at amortized cost. Accounts 
payable and accrued liabilities and amounts payable on mineral property acquisition are classified as other 
financial liabilities and thus, measured at amortized cost. The Company measures derivatives and embedded 
derivatives at fair value and the Company has maintained its policy not to use hedge accounting. 
 
Transaction costs incurred upon the issuance of debt instruments or modification of a financial liability are 
deducted from the financial liability and are amortized using the effective interest method over the expected life 
of the related liability. 
 
(n) Use of estimates 
 
The preparation of financial statements requires management to make estimates and assumptions that affect the 
reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the 
financial statements and the reported amounts of revenue and expenses during the reporting period. Significant 
areas requiring the use of management estimates relate to the determination of impairment of mineral properties, 
determination of asset retirement and remediation obligations, the assumptions used in determining fair value of 
stock-based compensation and valuation allowances for future income tax assets. Actual results could differ from 
these estimates. 
 
3. New accounting pronouncements 
 
(a) Business Combinations 
 
In October 2008, the CICA issued Handbook Section 1582, "Business Combinations", which establishes new standards 
for accounting for business combinations. This is effective for business combinations for which the acquisition 
date is on or after the beginning of the first annual reporting period beginning on or after January 1, 2011. 
Should the Company engage in a future business combination, it would consider early adoption to coincide with the 
adoption of International Financial Reporting Standards. 
 
(b) Non-controlling Interests 
 
Also in October 2008, the CICA issued Handbook Section 1602, "Non-controlling Interests", to provide guidance on 
accounting for non-controlling interests subsequent to a business combination. This is effective for fiscal years 
beginning on or after January 1, 2011. 
 
(c) International Financial Reporting Standards (IFRS) 
 
In February 2008, the Accounting Standards Board ("AcSB") confirmed that 2011 is the changeover date for publicly- 
listed companies to use IFRS. The date is for interim and annual financial statements relating to fiscal years 
beginning on or after January 1, 2011. The changeover date of January 1, 2011, will require the 2010 comparatives 
to be presented according to IFRS. 
 
Key dates: 
 
- January 1, 2010 (transition date): An opening statement of financial position according to IFRS will be prepared 
as at this date to facilitate the changeover to IFRS in 2011. The Company will continue to report its fiscal 2010 
and comparative 2009 results according to Canadian GAAP. 
 
- January 1, 2011 (changeover date): The date after which the Company will prepare and report interim and annual 
2011 financial statements with 2010 comparatives according to IFRS. 
 
The Company has identified the following impacted areas: 
 
(i) Functional currency 
 
Under Canadian GAAP -- Companies apply criteria to determine whether a foreign subsidiary's operation is 
integrated or self-sustaining, in which case the temporal and current methods of translation, respectively, are 
then applied to the subsidiary's financial statement balances and results of operations. The Company uses the 
temporal method to translate foreign currency transactions into Canadian dollars. 
 
Under IFRS -- The concepts of integrated and self-sustaining foreign operations do not exist under International 
Accounting Standards ("IAS") 21, The Effects of Changes in Foreign Exchange Rates. Under IAS 21, a reporting 
entity and each of its foreign operations must identify its "functional currency", defined as "the currency of the 
primary economic environment in which the entity operates." Management has determined that the functional currency 
of Greystar Resources Ltd., its Colombian branch and subsidiaries is the U.S. dollar as this is the currency of 
the primary economic environment in which the Company operates. 
 
(ii) Share-based payments 
 
Under Canadian GAAP -- The fair value of stock-based awards with different vesting dates 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. 
 
(iii) 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 are denominated in Canadian dollars. 
Because the functional currency of the Company is the U.S. dollar under IFRS, the share purchase warrants meet the 
definition of derivatives and will be measured as financial liabilities at fair value through profit or loss 
("FVTPL") at date of the grant and the end of each reporting period. The fair value of the share purchase warrants 
is determined using the Black Scholes option pricing model. 
 
(iv) 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. As the share purchase warrants will be classified as warrant liabilities, the 
residual method will be used to allocate the gross proceeds to common shares and warrant liability as required by 
IAS 32. 
 
(v) Environment rehabilitation 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. 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. 
 
(vi) Amounts payable on exploration and evaluation asset acquisition 
 
Under Canadian GAAP - The Company acquired surface rights for which some payments are due in the future. This 
obligation has been recorded as amounts payable on exploration and evaluation asset acquisition and have been 
discounted to reflect its non-interest bearing feature. The Company used credit-adjusted pre-tax risk-free 
interest rate to discount this obligation and record the value of the mineral interest. 
 
Under IFRS - The discount rate used to determine the present value of this obligation is the pre-tax rate that 
does not reflect risks for which future cash flow estimates have been adjusted. 
 
(vii) Change in presentation currency 
 
The Company currently presents its financial statements in Canadian dollars. The Company expects to present its 
financial statements in US dollars under IFRS. This change in presentation currency will result in a cumulative 
translation adjustment and under IFRS 1, the Company will elect to eliminate the cumulative translation adjustment 
on the IFRS transition date. 
 
The Company is in the process of determining the effect of these items noted above for presentation in the first 
quarter interim financial statements for 2011.

5. Mineral properties 
 
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 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 December 31, 2010, the required annual fee payments related to the Company's mineral properties 
totaled approximately $620,000 (2009 - $611,000). 
 
(a) Acquisition costs 
 
                                             2010         2009 
Acquisition costs, beginning of year $ 18,590,951 $ 14,418,247 
Additions during the year               2,312,795    4,172,704 
Acquisition costs, end of year       $ 20,903,746 $ 18,590,951 
 
Additions to mineral properties during the year ended December 31, 2010, relate to a combination of $2,066,512 
cash consideration and 95,000 share purchase warrants issued. The warrants issued to purchase the Company's common 
shares have a term of 4 years with exercise prices ranging from $3.65 to $4.17 and maturity dates ranging from 
July 28, 2014 through October 21, 2014. The value of the share purchase warrants issued was estimated to be 
$246,283 using the Black--Scholes valuation model applying risk free rates ranging from 1.79% to 2.42%, expected 
lives based on the full term of the warrants, expected dividends of nil, and volatility rates ranging from 74.8% 
to 83.7%. 
 
Additions to mineral properties during the year ended December 31, 2009, relate to a combination of $2,557,889 
cash consideration and 628,500 share purchase warrants issued. The warrants issued to purchase the Company's 
common shares have a term of 4 years with exercise prices ranging from $2.05 to $6.75 and maturity dates ranging 
from January 11, 2012 through June 29, 2013. The value of the share purchase warrants issued was estimated to be 
$1,614,815 using the Black--Scholes valuation model applying risk free rates ranging from 1.39% to 3.45%, expected 
lives based on the full term of the warrants, expected dividends of nil, and volatility rates ranging from 48.4% 
to 80.3%. 
 
In June 2009, the Company acquired the "Las Puentes" land parcel for $2,037,318 (COP4,010,000,000). A cash payment 
of $1,017,920 (COP 1,860,000,000) was made on the acquisition date, with further payments of approximately 
$595,700 (COP1,150,000,000) payable in April 2010 and $518,000 (COP1,000,000,000) payable in April 2011. 
 
Pursuant to the agreement, the Company was required to make a progress payment of approximately $595,700 
(COP1,150,000,000) in April 2010 for the Las Puentes land parcel. However, certain of the original Las Puentes 
vendors are currently in a title dispute with another unrelated group. The Company believes that its title is not 
at risk, and has decided not to make the $595,700 payment until the title dispute amongst the vendors and the

The future obligations have been recorded as amounts payable on mineral property acquisition on the consolidated 
balance sheet and have been discounted to reflect the non-interest bearing feature of this obligation. The 
discounted value of the future payments recognized on the date of acquisition was $1,019,398 and is being accreted 
to earnings at a rate of 12%. The discounted amount of $1,099,339 includes accretion at 12% and the effects of 
exchange rate differences as at December 31, 2010. 
 
In November 2009, the Company entered into a binding purchase agreement with a private Colombian company for an 
exclusive option to acquire a 100% working interest in the 78 hectares La Plata property ("La Plata"). The terms 
of the purchase agreement include staged payments totaling US$1,900,000 and the issuance of 160,000 share purchase 
warrants to acquire a 100% working interest in the property. During the year ended December 31, 2010, the Company 
made $1,345,959 (US$1,300,000) (2009 - $302,636 (US$300,000)) of the required staged payments and issued the share 
purchase warrants. Subsequent to year end, the Company made the final $297,332 (US$300,000) staged payment and has 
therefore, fully acquired the 100% working interest. The Company is required to incur minimum annual exploration 
expenditures aggregating approximately $745,950 (US$750,000) and to drill an aggregate of 4,000 meters on the 
property over a four year period starting in November 2009. In addition, if the Company develops an economically 
viable ore body at La Plata, the Company will pay a one-time payment of US$7 per ounce of gold and US$0.10 per 
ounce of silver for extractable reserves up to a maximum of 750,000 ounces.

6. Asset retirement obligation 
 
As at December 31, 2010, the Company had an asset retirement obligation of $1,163,223 (2009 - $1,342,855) relating 
to the remediation of environmental disturbances on the Angostura project. The obligation is based on $1,524,556 
of undiscounted estimated cash flows required to settle the obligation in the future.  Assumptions used by 
management to determine the carrying amount of the asset retirement obligation were a 12% credit-adjusted risk- 
free rate, a 15 - 25% mark-up in costs to reflect anticipated third party contractor costs 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 asset retirement obligation 
associated with the Angostura Project:

7. Share capital 
 
(a) Authorized 
 
Unlimited common shares without par value. 
 
(b) Issued and outstanding 
 
As of December 31, 2010, the Company had 84,222,987 common shares issued and outstanding (2009 -- 72,360,764). 
 
During the year ended December 31, 2010, a total of 11,700,261 shares of the Company were issued upon the exercise 
of warrants at prices between $2.47 and $4.30 per share for total proceeds of $46,062,723 of which $86,357 relates 
to the exercise of agents' warrants. As a result of these exercises, $11,969,381 previously recorded as warrants 
in shareholders' equity was transferred to share capital. For the year ended December 31, 2010, a total of 161,962 
shares of the Company were issued upon the exercise of options at prices between $0.85 and $4.71 per share for 
total proceeds of $371,763. As a result of these exercises, $633,541 was transferred from contributed surplus to 
share capital. 
 
On March 20, 2009, the Company completed a private placement of 6,579,161 units at a price of $1.83 per unit for 
gross proceeds of $12,039,865. Each unit consisted of one common share and three-quarters of a transferable common 
share purchase warrant. A total of 6,579,161 common shares and 4,934,371 warrants were issued on closing. The 
Company allocated $7,874,898 of gross proceeds to share capital and allocated $4,164,967 to warrants using the 
relative fair value method. The Company incurred $191,627 of issue costs with $125,338 allocated to common shares 
and $66,289 allocated to warrants. Each whole warrant entitles the holder to purchase one common share at a price 
of $2.47 per share during the five-year period ending March 20, 2014. If at any time following six months from 
March 20, 2009, the closing price of the Company's common shares on the Toronto Stock Exchange (TSX) is above 
$3.70 for 30 or more consecutive trading days, the Company can give notice to accelerate the expiry date of up to 
2,467,185 warrants to 60 days following the date of such notice. During 2010, this condition was met and the 
Company accelerated the expiry date resulting in 2,467,185 warrants being exercised. Additionally, if at any time 
following two months from the completion and delivery of a bankable feasibility study with respect to the 
Company's Angostura gold-silver project, the closing price of the Company's common shares on the TSX is above 
$3.70 for 30 or more consecutive trading days, the Company can give notice to accelerate the expiry of the 
remaining 2,467,186 warrants (or less) to 60 days following the date of such notice. The value of the warrants 
issued as part of this private offering was estimated using the Black-Scholes valuation model with the following 
assumptions: 
 
Risk-free interest rate         1.85% 
Expected life                5 years 
Volatility                        72% 
Expected dividends               Nil 
 
On September 29, 2009, the Company closed a public offering of 18,071,429 units at a price of $3.50 per unit for 
gross proceeds of $63,250,000. Each unit consisted of one common share and one-half of a transferable common share 
purchase warrant. A total of 18,071,429 common shares and 9,939,285 warrants were issued on closing, including 
903,571 warrants issued as compensation to the agents assisting with the offering. The Company allocated the gross 
proceeds of $53,013,442 to share capital and $10,236,558 to warrants using the relative fair value method. The 
Company incurred $5,147,610 of issue costs with $4,314,495 allocated to common shares and $833,115 allocated to 
warrants. The 9,035,714 warrants subscribed to in this offering entitle the holder to purchase one common share at 
a price of $4.30 per share during the one-year period ending September 29, 2010. If at any time, the closing price 
of the Company's common shares on the TSX is greater than $5.00 for 20 or more consecutive trading days, the 
Company can give notice to accelerate the expiry date of the warrants to 20 days following the date of such 
notice. During 2010, this condition was met and the Company accelerated the expiry date resulting in 9,233,076 
being exercised and 21,529 warrants expiring. Of these warrants, the Company received $194,265 due to the 
allotment to be issued pursuant to the exercise of 45,178 warrants. The Company also issued 127,000 common shares 
in 2009 and received cash proceeds of $546,100 subsequent to December 31, 2009. The 903,571 agents' warrants 
entitle the holder to purchase one unit at a price of $3.50 per unit during the one-year period ending September 
29, 2010, with each unit comprised of one common share and one-half of a transferable common share purchase 
warrant and having the same terms as the units subscribed to as part of the September 29, 2009 public offering. 
The value of the agents' warrants was estimated to be $1,359,965 using the Black-Scholes valuation model and has 
been recorded as an issue cost of this transaction. The valuation of the warrants issued as part of this public 
offering was estimated using the Black-Scholes valuation model with the following assumptions: 
 
Risk-free interest rate        1.20% 
Expected life                1 year 
Volatility                      119% 
Expected dividends              Nil 
 
(c) Share purchase 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. All stock options will automatically vest in the event of a change in control as defined in the Plan. 
 
The share option plan also provides for a cashless exercise option provision which is in substance a stock 
appreciation right which calls for settlement by the issuance of equity instruments. Stock-based employee awards 
that include stock appreciation rights are accounted under the fair value based method. During the year ended 
December 31, 2010, the Company granted to directors, officers, employees and consultants a total of 3,095,750 
options with vesting periods ranging from immediate vesting to vesting one third on each one year anniversary from 
the date of grant. The options are exercisable for up to five years from date of grant. The estimated fair value 
of the 2010 stock options granted at the date of option grant is $8,321,512 of which $3,309,518 has been recorded 
in stock-based compensation during the year ended December 31, 2010. 
 
During the year ended December 31, 2009, the Company granted a total of 1,510,000 options with vesting periods 
ranging from immediate vesting to vesting one third on each one year anniversary from the date of grant. The 
options are exercisable for up to five years from date of grant. The estimated fair value of the stock options 
granted at the date of option grant was $3,241,456. 
 
The Company recorded total stock based compensation expense of $4,515,330 for the year ended December 31, 2010 
(2009 - $2,305,684), and will record additional expenses of $5,974,623 as the remaining options become vested. 
 
The weighted average assumptions used to estimate the fair value of options granted were: 
 
                                2010     2009 
Risk-free interest rate         2.42%    1.75% 
Expected life                5 years  5 years 
Volatility                      77.5%    72.6% 
Expected dividends               Nil      Nil

the Company at the close of the business on November 19, 2003, and one right will attach automatically to each 
common share issued thereafter. 
 
The rights will trigger and become exercisable ten trading days after the occurrence of certain events including 
the acquisition or announcement of an intention to acquire by a person, including any persons related to or acting 
jointly or in concert with such person, of 20% or more of the Company's outstanding common shares, other than by 
an acquisition that complies with the permitted bid provisions of the Rights Plan or by an acquisition in respect 
of which the board of directors has waived the application of the Rights Plan. The initial exercise price of the 
rights is $25.00, subject to adjustments set forth in the Rights Plan. The expiry date for the rights plan has 
been extended from December 20, 2007 to December 20, 2013.

12. Management of financial risk 
 
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 
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 Canadian dollar relative to the Colombian 
peso and U.S. 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 cash and cash equivalents held in 
Canadian dollars at December 31, 2010 was $92,426,285 (2009 - $78,615,797). 
 
The Company's exposure to the Colombian peso, expressed in Canadian dollars and Colombian pesos, on financial 
instruments is as follows: 
 
                                                        2010                        2009 
                                                  CDN$  Colombian peso         CDN$  Colombian peso 
Cash and cash equivalents                  $    93,227     179,975,804  $   598,289   1,170,819,961 
Accounts receivable and prepaid expenses       524,882   1,013,284,852      337,783     661,023,483 
Accounts payable and accrued liabilities     2,400,242   4,633,672,085    1,761,310   3,446,790,607 
                                           $ 3,018,351   5,826,932,741  $ 2,697,382   5,278,634,051 
 
As at December 31, 2010, with other variables unchanged, a 10% depreciation or appreciation of the Canadian 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 $301,800. 
 
The Company's exposure to the Colombia peso on annual exploration expenditures throughout the year ended December 
31, 2010 was $17,718,266. A 10% depreciation of the Canadian dollar against the Colombian peso would affect the 
consolidated statement of operations and comprehensive loss by approximately $1,771,827. 
 
The Company's exposure to the U.S. dollar, expressed in Canadian dollars and U.S. dollars, on financial 
instruments is as follows: 
 
 
/T/ 
 
                                                    2010                    2009

Cash and cash equivalents                 $1,746,735  $1,754,234  $   44,494  $  42,513 
Accounts payable and accrued liabilities   1,151,856   1,158,110     225,631    215,585 
                                          $2,898,591  $2,912,344  $  270,125  $ 258,097 
 
/T/ 
 
As at December 31, 2010, with other variables unchanged, a 10% depreciation or appreciation of the Canadian dollar 
against the U.S. dollar would change the values of the U.S. dollar denominated financial instruments and would 
affect the consolidated statement of operations and comprehensive loss by approximately $289,859. 
 
The Company's exposure to the U.S. dollar on annual exploration expenditures throughout the year ended December 
31, 2010 was $5,943,565. A 10% depreciation of the Canadian dollar against the U.S. dollar would affect the 
consolidated statement of operations and comprehensive loss by approximately $594,357. 
 
(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 quality financial institutions 
and is available on demand for the Company's programs and is not invested in any asset backed commercial paper. 
Contractual commitments that the Company is obligated to pay in future years are disclosed in note 14. 
 
As at December 31, 2010, the Company's liabilities have contractual maturities as summarized below: 
 
                                                         Less than 
                                                Total       1 year 
Accounts payable and accrued liabilities  $ 6,308,617  $ 6,308,617 
Accounts payable on mineral properties      1,113,700    1,113,700 
                                          $ 7,422,317  $ 7,422,317 
 
(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 $983,000. 
 
(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 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 December 31, 2010. 
 
                                                     Financial assets at fair value

13. Capital management 
 
The Company's objective when managing capital is to maintain adequate levels of funding in order to support 
exploration and development of its projects in Colombia and to maintain corporate and administrative functions. 
The Company considers shareholders' equity as capital. 
 
The Company is not subject to externally imposed capital requirements and the Company's overall strategy with 
respect to capital risk management remains unchanged from the prior year (see note 1 for additional information).

1. HIGHLIGHTS 
 
Results of Operations 
 
The net loss for the year ended December 31, 2010, was $35.9 million compared to $24.0 million for the comparative 
period in 2009. Loss per share for the years ended December 31, 2010 and 2009 was $0.43. 
 
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. On April 20, 2010, MAVDT requested a new EIA that 
conforms to new regulation Law 1382 of 2010 (Modified Mining Code) which requires that mining and exploration 
activity must be excluded from the "Paramo" ecosystem. On April 29, 2010, the Company filed an appeal of the 
notification from MAVDT regarding the EIA. On May 28, 2010, the Company received a letter from MAVDT that 
reinstated its review of the Company's EIA as originally filed. On July 15, 2010, MAVDT issued a notice to the 
Company that, at the request of third parties, Information Meetings for local communities planned by the Company 
needed be incorporated into a public hearing process. The Company held two Informational Hearings on November 3 
and 4, 2010, and the Public Hearing on November 21, 2010, to hear the views and opinions of certain interested 
parties on the environmental impact of the Angostura Project. These Information and Public Hearings are steps in 
the process relating to the decision from MAVDT on issuing an environmental permit for the Angostura Project. 
 
In December 2010, MAVDT notified the Company of a requirement of another Information Meeting and Public Hearing 
for the environmental permitting process to be held in the city of Bucaramanga. This decision was based on the 
fact that certain participants opposing the Angostura Project, who had registered to address the general public 
during the first hearing process, were in the petitioner's view, unable to participate on account of alleged 
restrictions in the road heading to California, Santander, the location of the first hearing. This exceptional 
request was intended to better allow inhabitants of Bucaramanga to express their views on the Angostura Project 
and for MAVDT to obtain public testimony or comments on the Angostura Project's EIA. The Information Meeting was 
held on February 17, 2011, and the Public Hearing held on March 4, 2011. Unfortunately, confrontations during the 
Public Hearing resulted in the representatives of MAVDT cancelling the Public Hearing after 28 of the inscribed 
470 statements had been heard. 
 
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" (which in this context, means to cease the Company's intention of further pursuing a 
formal petition or request for the administrative procedure for an environmental license at this time with a 
Colombian governmental entity, but without prejudice of the right and opportunity to file a new petition or 
request for administrative procedure for a mining project environmental license in the future) from ongoing 
environmental licensing to allow for future re-filing on terms that reflects concerns. On the March 23, 2011, the 
Company filed a request to desist from the administrative procedure of the environmental licensing before MAVDT. 
The Company is committed to developing the Angostura Project, but recognizes that there is a need to reconfigure 
it. 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 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. The Company has completed a 
Preliminary Economic Evaluation ("PEE") of an underground operation at the Angostura Project that targets the high 
grade resource at Angostura. The Company proposes to work rapidly to advance the next phase of study and drilling 
with an objective to increase and improve the categorization of high grade underground resources, and 
investigating the potential to extend the resource at length and depth. 
 
The PEE indicates that over a 14 year initial project life, gold production is estimated at 2 million ounces of 
gold and 8 million ounces of silver. Production costs are estimated at US$395 per ounce of gold after silver 
credits. The initial capital cost is estimated at US$352 million. At a long term gold price of US$1,015 per ounce 
of gold, US$15.85 per ounce of silver and a discount rate of 5%, the pre-tax net present value ("NPV") is US$412 
million and the internal rate of return ("IRR') is 20%. Mineral resources that are not mineral reserves do not 
have a demonstrated economic viability. The Company will file a National Instrument 43-101 compliant Technical 
Report within 45 days from March 18, 2011. 
 
The Company will complete all necessary steps to ensure that the Angostura Project will not affect the water 
supply or its quality to the city of Bucaramanga, the surrounding metropolitan area, or the North Soto Province. 
The Company will continue to inform citizens fully about its proposed Angostura Project and to encourage an 
understanding that responsible mining can bring considerable economic and social benefits, not only to the region, 
but to Colombia as a whole. 
 
International Cyanide Management Code 
 
In September 2010, the Company announced that The International Cyanide Management Institute ("ICMI") has accepted 
the Company as a signatory to the International Cyanide Management Code for the Manufacture, Transport and Use of 
Cyanide in the Production of Gold ("Code"). The Code is a voluntary industry program for companies involved in the 
production of gold using cyanide and companies manufacturing and transporting this cyanide. 
 
By becoming a signatory, the Company commits to follow the Code's Principles and implement its Standards of 
Practice and to have verification audits of the Angostura Project conducted by independent third-party auditors 
during its pre-operational phase, within one year of its first receipt of cyanide, and every three years 
thereafter. 
 
Management Changes 
 
In February 2010, the Company announced the appointment of Mr. Steve Kesler to the position of President and CEO 
following receipt of a Canadian work permit. Mr. Kesler assumed the role of President and Chief Executive Officer 
in May 2010 following the retirement of Mr. David Rovig who was appointed as non-executive Chair of the Board. In 
April 2010, Tim Lallas resigned as Vice-President Finance, Administration and Chief Financial Officer.  Rick Low, 
the Company's Director Finance, acted as interim Chief Financial Officer until the appointment of David Newbold as 
Chief Financial Officer in August 2010.  In June 2010, Geoff Chater stepped down as Vice President Corporate 
Development, but continued to provide investor relations consulting services until October 2010. In September 
2010, the Company announced the appointment of Victoria Vargas as Vice President Investor Relations and Corporate 
Communications. David Heugh was appointed to the position of Chief Operating Officer in March 2011.

The variation in total assets over the three year term is mainly due to fluctuations in levels of cash. As the 
Company has no operating revenue, it relies primarily on equity financing to fund its activities. Proceeds from 
equity financing, including exercise of stock options and warrants, were $46 million, $76 million and $294,000 in 
2010, 2009 and 2008, respectively. Interest income increased in 2010 due to the higher level of cash balance 
compared to 2009. Interest rates on investments for 2008 were higher resulting in higher interest income compared 
to subsequent years. Funds raised have been used primarily for exploration activities and mineral property 
acquisitions at the Angostura Project. Over the three year period, exploration costs have trended up from a 
monthly average of $1.7 million in 2008 to $2.2 million in 2010, due to costs incurred for the preparation of the 
prefeasibility and feasibility studies. Administrative costs have increased in step with the level of exploration 
activity, additional administrative personnel and professional fees as the Company transitions from exploration to 
development. At December 31, 2010, cash and cash equivalents represented approximately $98.3 million out of the 
$121.1 million of total assets. 
 
Stock-based compensation costs, primarily stock options granted to directors and employees of the Company, were 
the largest single component of administrative expenses during 2010 and 2009. Stock based compensation costs are a 
non-cash expense and represent an estimate of the fair value of stock options granted to directors, employees and 
consultants of the Company. 
 
3. ANGOSTURA GOLD¡SILVER PROJECT UPDATE, COLOMBIA 
 
Historical information on the Angostura Project follows the current and latest developments, which are discussed 
immediately below. 
 
Current Developments 
 
The Company's permitting process for the Angostura Project is described under "Permitting" below. This process 
involved the filing of an EIA in 2009 and 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 
reflects concerns. On the March 23, 2011, the Company filed a request to desist from the administrative procedure 
of the environmental licensing before MAVDT. 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 reconfigure it. 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. The Company has completed a Preliminary Economic Evaluation of an underground operation at the Angostura 
Project that targets the high grade resource at Angostura. The Company proposes to work rapidly to advance the 
next phase of study and drilling with an objective to increase and improve the categorization of high grade 
underground resources, and investigating the potential to extend the resource at length and depth. 
 
The PEE indicates that most of these resources are contained within the shell of the open pit. Mineable resources 
were estimated at 14 million tonnes at 5.34 grams per tonne ("g/t") gold and 29.6 g/t silver. A mining rate of 
4,000 tonnes per day ("tpd") and flotation plant operation of 3,300 tpd are envisaged, which after a ramp up of 
one year, would produce approximately 200,000 ounces of gold per year over the first seven years before production 
declines owing to resource constraints. The PEE indicates that over a 14 year initial project life, gold 
production is estimated at 2 million ounces of gold and 8 million ounces of silver. Production costs are estimated 
at US$395 per ounce of gold after silver credits. The initial capital cost is estimated at US$352 million. At a 
long term gold price of US$1,015 per ounce of gold, US$15.85 per ounce of silver and a discount rate of 5%, the 
NPV is US$412 million and the IRR is 20%. Mineral resources that are not mineral reserves do not have a 
demonstrated economic viability. 
 
The Company is committed to the reclamation of all areas affected by the Angostura Project and to develop a 
biodiversity offset program. The Company believes that the oxide resource can be developed with open pit mining 
whilst preserving biodiversity and water quality. The Company wants to ensure that the future re-filing reflects 
the many concerns that have been presented and that this will allow it to have a social license to operate 
sustainably. The Company will complete all necessary steps to ensure that the Angostura Project will not affect 
the water supply or its quality to the city of Bucaramanga, the surrounding metropolitan area, or the North Soto 
Province. The Company will continue to inform citizens fully about its proposed Angostura Project and to encourage 
an understanding that responsible mining can bring considerable economic and social benefits, not only to the 
region, but to Colombia as a whole. 
 
Historical Development of Resources 
 
On March 18, 2011 the Company announced its commitment to developing the Angostura Project, but recognized that 
there is a need to reconfigure it. The definition of resources prior to this date is set out below for reference. 
 
On July 15, 2010, Greystar announced an updated resource estimate for the Angostura Project. The resource study 
was based on updated three dimensional geological and mineral models It included all of the technical data 
available as of January 2010, including 179,813 core assays from 938 drill holes representing 302,834 meters, and 
1,768 muck samples from the exploration tunnels. The resource study was developed by Greystar under the overall 
supervision of consulting company NCL Ingenierfa y Construccion S.A. ("NCL") from Santiago, Chile. 
 
Additional drilling carried out in 2008 and the rigorous evaluation of the resource by Greystar's geological staff 
working closely with NCL had provided a robust resource model. Greystar had initiated the evaluation of 
underground resources that lie beyond the pit boundary but within a proximity to allow exploitation utilizing the 
pit infrastructure either during or after completing the open pit operation. As the cut-off date for the data 
employed in this resource study was January 2010, drilling data from the Los Laches, Cristo Rey and Silencio 
properties received after that date was not included. 
 
Resource Highlights: 
 
This resource statement was made using a gold price of US$850/oz and a silver price of US$12/oz. In developing 
this resource, a more conservative view was taken on higher grade material, which included grade capping and 
reduced search area to make the resource more robust and to enhance the overall economic evaluation of the 
viability of the Angostura Project. An operational pit was designed by NCL using available mining, metallurgical 
and geotechnical parameters. Details of the operational pit and underground resources are provided in the tables 
below:

Underground Resource 
 
The PEE referred to in the March 18, 2011 update addresses a different resource that would be accessed by 
underground methods rather than open pit. Such minable resources were estimated at 14 million tonnes at 5.34 g/t 
gold and 29.6 g/t silver. 
 
The following discusses the smaller underground resource as contained in the July 15, 2010 updated resource 
estimate for the open pit Angostura Project. 
 
The portions of the block model beneath the operational pits were examined to determine the zones which might 
support the necessary capital for underground development. The portions that were too isolated from the pit 
infrastructure or with insufficient grade or tonnage for underground mining were categorized as waste.

On July 15, 2010, Greystar announced an updated metallurgical recovery model ("Recovery Model") and process flow 
for the Angostura Project. The updated Recovery Model replaces the metallurgical model used in the May 2009 
Preliminary Feasibility Study ("PFS Recovery Model"). 
 
The results of the metallurgical testing have the following average gold recoveries by ore type.

samples tested at 38 mm). 
 
3. Heap Leach average metallurgical results in the Recovery Model based on 11 CLT at 38 mm. 
 
4. High grade ore circuit average metallurgical results in the PFS Recovery Model were based on the sale of 
concentrates with 90% flotation gold recovery, 98.5% Smelter Recovery, and 54% heap leaching recovery of flotation 
tails agglomerates. 
 
5. High grade ore circuit average metallurgical results in the Recovery Model based on 91% flotation gold 
recovery, 90% BIOX([R]) /CIP recovery, and 50% heap leaching recovery of flotation tails agglomerates. 
 
6. Heap leach feed size sensitivity (38mm vs. 19mm) employed for the Recovery Model was determined considering 
only samples tested at both feed sizes, rather than average results as presented in the table shown above. 
 
Updates to the Recovery Model included: 
 
- A coarsening of the planned heap leach feed size to 38mm. 
 
- A new geo-metallurgical model to project heap leach recoveries. 
 
- A revision to the high grade recovery circuit to include stirred tank bio-oxidation and carbon-in-pulp 
cyanidation of the flotation concentrate. 
 
The metallurgical processing routes for the Angostura ore would have been driven by the Recovery Model with: 
 
- Oxide, transitional and low-grade sulphide ore being processed by conventional cyanide heap leach and 
agglomerated flotation tailings heap leach, and 
 
- High grade sulphide mineralization being treated by milling, flotation, stirred tank bio- oxidation, carbon in 
pulp cyanidation of bio-oxidized residue and pulp agglomeration heap leaching of flotation tailings. 
 
Permitting 
 
Date:             Event: 
 
October, 2009     The Company submitted an application for a Work and Investment Plan 
                  (PTO) based on the preliminary feasibility study ('PFS"). The PTO was 
                  submitted to the Ingeominas, a division in the Ministry of Mines and 
                  Energy, on October 23, 2009. The PTO is the operating plan for 
                  Angostura which must be approved by Ingeominas in a parallel process to 
                  the environmental permitting. Both the EIA and the PTO must be 
                  approved in order to begin the construction phase of the Mining 
                  Concession Contract. 
 
December, 2009    The Company filed the EIA with MAVDT to initiate the environmental 
                  permitting process for the development of an open pit gold and silver mine 
                  at the Angostura Project in Colombia. The EIA, which is based on the PFS, 
                  covers all environmental and social aspects of the proposed mine 
                  development including baseline data and end of mine life mitigation plans. 
 
April, 2010       MAVDT requested a new EIA to be filed. MAVDT requested that the new 
                  EIA conform to new regulation Law 1382 of 2010 (Modified Mining 
                  Code) which requires that mining and exploration activity must be 
                  excluded from the "Paramo" ecosystem. 
 
May, 2010         After the Company's appeal in April 2010, the Company received a writ 
                  from MAVDT that reversed its April 20th writ and reinstated the 
                  December 22, 2009 EIA as filed. MAVDT advised it would move forward 
                  with a review of the EIA. 
 
November 2010     After MAVDT's notice in July 2010, stating that the Information Meetings 
                  for local communities that were being planned by the Company are to be 
                  incorporated into a public hearing process, the Company held two 
                  Informational Hearings on November 3 and 4, 2010 and the Public Hearing 
                  on November 21, 2010. The Informational Hearing was held in the towns 
                  of California and Vetas Santander, Colombia and the Public Hearing held 
                  only in the town of California. 
 
March 2011        In December 2010, MAVDT notified the Company of a requirement of 
                  another Information Meeting and Public Hearing for the environmental 
                  permitting process to be held in the city of Bucaramanga. This decision 
                  was based on the fact that certain participants opposing the Angostura 
                  Project, who had registered to address the general public during the first 
                  hearing process, were in the petitioner's view, unable to participate on 
                  account of alleged restrictions in the road heading to California, Santander, 
                  the location of the first hearing. This exceptional request was intended to 
                  better allow inhabitants of Bucaramanga to express their views on the 
                  Angostura Project and for MAVDT to obtain public testimony or 
                  comments on the Angostura Project's EIA. These Information and Public 
                  Hearings are steps in the process relating to the decision from MAVDT on 
                  issuing an environmental permit for the Angostura Project. The 
                  Information Meeting was held on February 17, 2011 and the Public 
                  Hearing held on March 4, 2011. Unfortunately, confrontations during the 
                  Public Hearing resulted in the representatives of MAVDT cancelling the 
                  Public Hearing after 28 of the inscribed 470 statements had been heard. On 
                  the March 23, 2011, the Company filed a request to desist from the 
                  administrative procedure of environmental licensing before MAVDT, as 
                  well as the administrative procedure of evaluation and approval of the 
                  PTO before Ingeominas. 
 
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 area of the 
Angostura gold-silver deposit. The new drill results from the Los Laches Area, whose 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. 
 
Mongora Drill Program 
 
The Mongora prospect is defined by a large, 500 meter by 300 meter gold-in-soil anomaly. The Company started 57 
drill holes on the Mongora target, accumulating 19,459 meters to December 2010. 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 for the Angostura Project. 
 
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 17 drill holes (6,651 meters) 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. 
 
Cristo Rey 
 
3,778 meters of core has been drilled at Cristo Rey in 2010 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. 
 
New Areas of Exploration outside of the Angostura Project Area 
 
Greystar has applied for mineral property rights over 35,000 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. 
 
Besides the exploration for gold, a study of potential for limestone as a source of lime feed for a lime plant was 
completed on April 2009 in the Issuer's concessions in the areas of Charta and Vetas. Three potential areas as 
sources of limestone for a future plant were defined.

Three months ended December 31, 2010 
 
Total exploration expenditures were $9.6 million for the three months ended December 31, 2010, compared to $5.4 
million for the three months ended December 31, 2009. The change was the result of the following: 
 
- Costs related to feasibility study were $4.0 million for the three months ended December 31, 2010, compared to 
$1.8 million for the comparative period in 2009. The higher cost in 2010 was due to increased expenses in the 
process of finalizing the feasibility study. 
 
- Exploration costs were higher for the three months ended December 31, 2010, due to the drill programs at Los 
Laches, Mongora and La Plata properties. These drilling expenditures totalled $2.0 million in the three months 
ended December 31, 2010, compared to costs of $0.8 million in the comparative period of 2009. 
 
- General and administrative expense for the Angostura Project in Colombia was $2.4 million for the three months 
ended 2010 compared to costs of $1.1 million for the comparative period in 2009 due to increases in personnel, 
consultants and activities relating to public hearing. 
 
General and administrative expenses at the corporate office increased by approximately $1.3 million for the three 
months ended December 31, 2010, compared to the three months ended December 31, 2009. The increase was a result of 
the following: 
 
- Management and consulting fees were up $0.3 million in 2010 compared to 2009, due primarily to the engagement of 
consultants for finance advisory services, and corporate reorganization consulting services. 
 
- Salaries and benefits were up $0.3 million in 2010 compared to 2009, due primarily to the hiring of additional 
senior corporate staff during first half of 2010. 
 
- Stock-based compensation increased by $0.4 million in 2010 compared to 2009, due to higher amortization 
resulting from the higher number and fair values for stock options granted during the first half of 2010, and to 
higher amortization of the cost of prior period awards that vested during the period. 
 
- Travel costs were up by $0.1 million in 2010 compared to 2009, due primarily to increase travel by corporate 
staff resulting from increased activities in the hearing process, financing, recruitment and project site visits. 
 
- 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 anticipates moving into development. 
 
Interest income for the three months ended December 31, 2010, increased by $0.1 million from the comparative 
period in 2009, primarily due to the increased cash balances. 
 
The Company had a foreign exchange gain of $253,000 for the three months ended December 31, 2010, compared to a 
$70,000 loss for the three months ended December 31, 2009, primarily due to the conversion of Colombian peso 
denominated transactions and balances to Canadian dollars. 
 
Year ended December 31, 2010 
 
Total exploration expenditures were $26.3 million for the year ended December 31, 2010, compared to $19.2 million 
for the year ended December 31, 2009. The change was the result of the following: 
 
- Costs related to the feasibility study were $10.1 million for the year ended December 31, 2010, compared to $8.6 
million for the comparative period in 2009. The higher cost in 2010 was due to the increased expenses in the 
process of finalizing of the feasibility study. 
 
- Exploration costs were higher for the year ended December 31, 2010, due to the drill programs at Los Laches, 
Mongora and La Plata properties. These drilling expenditures totalled $6.4 million in 2010, compared to costs of 
$2.7 million in the comparative period of 2009. 
 
- General and administrative expense for the Angostura Project in Colombia increased by $2.3 million for the year 
ended December 31, 2010 compared to the comparative period of 2009 due to increases in personnel, consultants and 
activities relating to public hearing. 
 
General and administrative expenses at the corporate office have increased by approximately $6.0 million for the 
year ended December 31, 2010, compared to the year ended December 31, 2009. The following explains the increase in 
the comparative periods: 
 
- Management and consulting fees were up $1.6 million in 2010 compared to 2009, due primarily to the engagement of 
consultants to recruit senior executives, finance advisory services, and corporate reorganization consulting 
services. 
 
- Salaries and benefits were up $1.5 million in 2010 compared to 2009, due primarily to the hiring of additional 
senior corporate staff during 2010 and bonuses awarded to senior management during the first quarter of 2010 as 
compared to no bonuses in the comparative quarter of 2009. 
 
- Stock-based compensation increased by $2.2 million in 2010 compared to 2009, due to higher amortization 
resulting from the higher number and fair values for stock options granted during 2010, and to higher amortization 
of the cost of prior period awards that vested during the period. 
 
- Travel costs were up by $0.4 million in 2010 compared to 2009, due primarily to increase travel by corporate 
staff resulting from increased activities in the hearing process, financing, recruitment and project site visits. 
 
 
Interest income for the year ended December 31, 2010, increased by $0.8 million from the comparative period in 
2009, primarily due to the increased cash balances. 
 
The Company had a foreign exchange gain of $83,000 for the year ended December 31, 2010 compared to a $0.2 million 
loss for the year ended December 31, 2009. Gains recorded in the current year period can primarily be attributed 
to the conversion of Colombian peso transactions into Canadian dollars as the Colombian peso weakened against the 
Canadian dollar during the year.

Notes and Factors Affecting Comparability of Quarters: 
 
1. The Company is a mineral 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. This, however, was 
offset by the significantly increased levels of cash, which contributed to increasing level of quarterly interest 
income in 2010 compared to 2009. 
 
2. Stock-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. 
 
3. Exploration and other project-related activities in Colombia shut down each year for a Christmas break which 
extends into January. As a result of this shut-down, exploration and project-related expenditures for the December 
31 quarter and the March 31 quarter tend to be lower than the preceding September 30 quarter. For the quarters 
ended March 31, 2009 and June 30, 2009, the reduction of costs can be attributed to the time lag between the 
completion of the PFS and the start of the FS in late June 2009. For the second half of 2009, costs increased 
significantly due to efforts being placed on the FS. Engineering costs for the feasibility study decreased during 
the first quarter of 2010 but increased for the remainder of the year. 
 
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 anticipates moving into development. 
 
6. LIQUIDITY AND CAPITAL RESOURCES 
 
Statement of Cash Flow Information 
 
At December 31, 2010, cash and cash equivalents were $98.3 million, up from $81.6 million at December 31, 2009. 
The increase in cash and cash equivalents is primarily attributed to the receipt of gross proceeds of $46.1 
million received 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 $27.2 
million for the year ended December 31, 2010, compared to $20.0 million for the comparative period in 2009. For 
the year ended December 31, 2010, exploration-related expenditures, including feasibility study costs, were $26.3 
million and represent the major use of funds for the period. 
 
At December 31, 2010, the Company had working capital of $90.8 million, but had not yet achieved profitable 
operations and expects to incur further losses in the development of its business. For the year ended December 31, 
2010, the Company reported a net loss of $35.9 million and as at December 31, 2010, had an accumulated deficit of 
$173.2 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 project and 
administrative costs to the end of 2011. Financial advisors have been appointed to assist the Company in 
developing a financing plan for development of the Angostura Project. 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 Company's application for an 
environmental permit with the MAVDT, mineral prices, the results and recommendations of the FS, the political risk 
of operating in a foreign country, 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. Management intends to continue discussions with potential debt and equity investors. 
 
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 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 December 31, 2010, the required annual fee payments related to the Company's mineral properties 
totaled approximately $620,000 (2009 - $611,000). 
 
(b) Other Commitments 
 
The following is a schedule of the Company's other commitments as at December 31, 2010: 
 
                                                                                             2016 and

(a) Relates to various professional services and outsourced. 
 
(b) Primarily relates to operating leases for office premises 
 
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 
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 Canadian dollar relative to the 
Colombian peso and U.S. 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 Canadian dollars and Colombian pesos, on financial 
instruments is as follows: 
 
                                                       2010                       2009 
                                               CDN$  Colombian peso         CDN$  Colombian peso 
Cash and cash equivalents                  $ 93,227     179,975,804    $ 598,289   1,170,819,961 
Accounts receivable and prepaid expenses    524,882   1,013,284,852      337,783     661,023,483 
Accounts payable and accrued liabilities  2,400,242   4,633,672,085    1,761,310   3,446,790,607 
                                         $3,018,351   5,826,932,741  $ 2,697,382   5,278,634,051 
 
As at December 31, 2010, with other variables unchanged, a 10% depreciation or appreciation of the Canadian 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 $301,800. The 
Company's exposure to the Colombia peso on annual exploration expenditures throughout the year ended December 31, 
2010 was $17,718,266. A 10% depreciation of the Canadian dollar against the Colombian peso would affect the 
consolidated statement of operations and comprehensive loss by approximately $1,771,827. 
 
The Company's exposure to the U.S. dollar, expressed in Canadian dollars and U.S. dollars, on financial 
instruments is as follows: 
 
                                                      2010               2009 
                                               CDN$        US$        CDN$       US$ 
Cash and cash equivalents                $1,746,735 $1,754,234  $   44,494 $  42,513 
Accounts payable and accrued liabilities  1,151,856  1,158,110     225,631   215,585 
                                         $2,898,591 $2,912,344  $  270,125 $ 258,097 
 
As at December 31, 2010, with other variables unchanged, a 10% depreciation or appreciation of the Canadian dollar 
against the U.S. dollar would change the values of the U.S. dollar denominated financial instruments and would 
affect the consolidated statement of operations and comprehensive loss by approximately $289,859. 
 
The Company's exposure to the U.S. dollar on annual exploration expenditures throughout the year ended December 
31, 2010 was $5,943,565. A 10% depreciation of the Canadian dollar against the U.S. dollar would affect the 
consolidated statement of operations and comprehensive loss by approximately $594,357. 
 
(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 quality financial institutions 
and is available on demand for the Company's programs and is not invested in any asset backed commercial paper. 
Contractual commitments that the Company is obligated to pay in future years are disclosed in note 14. 
 
As at December 31, 2010, the Company's liabilities have contractual maturities as summarized below: 
 
                                                           Less than 
                                                 Total        1 year

Accounts payable on mineral properties       1,113,700     1,113,700 
                                           $7, 422,317   $7, 422,317 
 
(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 $983,000. 
 
(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 our financial assets and liabilities are described below: 
 
(iv) 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. 
 
(v) 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. 
 
(vi) 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 December 31, 2010.

9. CRITICAL ACCOUNTING ESTIMATES 
 
Mineral Property and Land Costs 
 
It is the Company's accounting policy that exploration and development expenditures incurred prior to the 
determination of the feasibility of mining operations are charged to operations as incurred. The Company's mineral 
property account on the balance sheet reflects actual costs incurred by it on acquisition costs of its properties. 
The realization of the Company's investment in these exploration projects is dependent upon various factors, 
including the discovery of economically recoverable reserves of minerals, the ability to obtain necessary 
financing to develop the  project's potential, approval of permits and licenses from the Colombian government, 
upon future profitable operations, or alternatively upon the disposal of interests on an advantageous basis. The 
Company reviews the carrying values of its projects on a quarterly basis and if required, makes an adjustment to 
reflect the project's realizable value. Capitalized costs will be amortized over the estimated useful life of the 
properties following the commencement of production. As at December 31, 2010, amounts capitalized to mineral 
properties total $20.9 million. 
 
Amounts Payable on Mineral Property Acquisition 
 
Included in the Company's balance sheet is the fair value of the amounts payable on mineral property acquisition. 
The fair value of the amounts payable on mineral property acquisition was determined by discounting the stream of 
future cash payments at the estimated prevailing market rate for a debt instrument of comparable maturity and 
credit quality. 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. 
 
Asset Retirement Obligation 
 
The asset retirement obligation has been estimated based on the Company's interpretation of current regulatory 
requirements and have been measured at fair value. Fair value is determined based on the net present value of 
expected future cash expenditures upon reclamation and closure. Environmental rehabilitation costs are charged to 
exploration costs. Because the fair value measurement requires the input of subjective assumptions, including the 
environmental rehabilitation costs and discount rate used, changes in subjective input assumptions can materially 
affect the fair value estimate. 
 
Income taxes 
 
Future income tax assets and liabilities are computed based on differences between the carrying amounts of assets 
and liabilities on the balance sheet and their corresponding tax values using substantively enacted income tax 
rates at each balance sheet date. Future income tax assets also result from unused loss carry-forwards and other 
deductions. The valuation of future income tax assets is reviewed quarterly and adjusted, if necessary, by use of 
a valuation allowance to reflect the estimated realizable amount. 
 
Fair value of stock-based compensation and warrants issued 
 
The fair value of stock-based compensation and warrants issued 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. NEW ACCOUNTING POLICIES 
 
(a) Business Combinations 
 
In October 2008, the CICA issued CICA Handbook Section 1582, "Business Combinations", which establishes new 
standards recognition, measurement, presentation and disclosure of business acquisitions. This standard is 
substantially aligned with International Financial Reporting Standards. This is effective for business 
combinations for which the acquisition date is on or after the beginning of the first annual reporting period 
beginning on or after January 1, 2011.  Should the Company engage in a future business combination, it would 
consider early adoption to coincide with the adoption of International Financial Reporting Standards. The Company 
is currently assessing the impact of this accounting standard on the Company's financial position and results from 
operations. 
 
(b) Non-controlling Interests 
 
In October 2008, the CICA issued CICA Handbook Sections 1601, "Consolidated Financial Statements" and 1602, "Non- 
controlling Interests", which provide revised guidance on the presentation of consolidated financial statements 
and accounting for non-controlling interests subsequent to a business combination. This guidance is effective for 
fiscal years beginning on or after January 1, 2011. The Company is currently assessing the impact of this 
accounting standard on the Company's financial position and results from operations. 
 
(c) International Financial Reporting Standards ("IFRS") 
 
In February 2008, the Accounting Standards Board ("AcSB") confirmed that 2011 is the changeover date for publicly- 
listed companies to use IFRS.  The date is for interim and annual financial statements relating to fiscal years 
beginning on or after January 1, 2011. The changeover date of January 1, 2011, will require the 2010 comparatives 
to be presented according to IFRS. 
 
Key dates: 
 
While the Company continues to perform detailed assessments of the impact of adopting IFRS, the Company has 
estimated the impact of IFRS to its opening financial position under IFRS as of January 1, 2010. In estimating the 
opening financial position, the Company has applied the following IFRS exemptions on first-time adoption. 
 
(i) 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. 
 
(ii) Cumulative translation differences 
 
As permitted by the IFRS 1 election for cumulative translation differences, the Company has deemed cumulative 
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. 
 
(iii) Share-based payments 
 
The Company has elected to apply IFRS 2 to awards unvested at the date of transition. IFRS has not been applied to 
awards that vested prior to January 1, 2010. 
 
(iv) Compound financial instruments 
 
The Company has elected to apply the exemption related to compound financial instruments. IAS 32 requires an 
entity to split a compound financial instrument at inception into separate liability and equity components. If the 
liability component is no longer outstanding, retrospective application of IAS 32 involves separating two portions 
of equity. However, in accordance with this IFRS, a first-time adopter need not separate these two portions if the 
liability component is no longer outstanding at the date of transition to IFRS. 
 
(v) Decommissioning liabilities 
 
The Company has elected to apply the exemption related to decommissioning liabilities. This exemption allows a 
first-time adopter to apply the requirements of IFRIC 1, dealing with changes in decommissioning liabilities, on a 
prospective basis from the date of transition. 
 
(vi) Leases 
 
The Company has elected to apply the transitional provisions of IFRIC Interpretation 4, "Determining Whether an 
Arrangement Contains a Lease". This election allows the Company 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. 
 
(vii) Borrowing costs 
 
In accordance with IFRS 1, the Company has elected to prospectively apply IAS 23 effective January 1, 2010. 
 
(viii) 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. 
 
The Company's estimated IFRS opening financial position as of January 1, 2010, together with estimated differences 
between IFRS and Canadian GAAP is presented below. The accompanying explanatory notes provide a description of the 
differences between Canadian GAAP and IFRS affecting the Company. The estimated financial position and differences 
have not been audited by the Company's auditors and are subject to change as the Company continues to perform 
detailed assessments of the impact of adopting IFRS.

Explanatory notes 
 
(a) Functional currency 
 
Under Canadian GAAP - Companies apply criteria to determine whether a foreign subsidiary's operation is integrated 
or self-sustaining, in which case the temporal and current methods of translation, respectively, are then applied 
to the subsidiary's financial statement balances and results of operations. The Company uses the temporal method 
to translate foreign currency transactions into Canadian dollars. 
 
Under IFRS - The concepts of integrated and self-sustaining foreign operations do not exist under IAS 21 "The 
Effects of Changes in Foreign Exchange Rates;" rather, a reporting entity and each of its foreign operations must 
identify its "functional currency", defined as "the currency of the primary economic environment in which the 
entity operates." Management has determined that the functional currencies of Greystar Resources Ltd., its 
Columbian branch and subsidiaries are the U.S. dollar as this is the currency of the primary economic environment 
in which the Company operates. The Company has converted transactions and balances denominated in foreign 
currencies into U.S. dollars in accordance with IFRS. 
 
(b) 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. 
 
(c) 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 are denominated in Canadian dollars, 
which is not the Company's functional currency, being the U.S. dollar. As a result, the share purchase warrants 
meet the definition of derivatives and are measured as financial liabilities at fair value through profit and loss 
('FVTPL") at grant date and the end of each reporting period. The fair value of the share purchase warrants is 
determined using the Black Scholes option pricing model. 
 
(d) 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. As the share purchase warrants are classified as liabilities, the Company 
allocated the gross proceeds to common shares and warrant liability using the residual method as required by IAS 
32. 
 
(e) Environment rehabilitation 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. In addition, 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. 
 
(f) Amounts payable on exploration and evaluation asset acquisition 
 
Under Canadian GAAP - The Company acquired surface rights for which some payments are due in the future. This 
obligation has been recorded as amounts payable on exploration and evaluation asset acquisition and have been 
discounted to reflect its non-interest bearing feature. The Company used credit-adjusted pre-tax risk-free 
interest rate to discount this obligation and record the value of the mineral interest. 
 
Under IFRS - The discount rate to be used to determine the present value of this obligation is the pre-tax rate 
that does not reflect risks for which future cash flow estimates have been adjusted. 
 
(g) Change in presentation currency 
 
The Company previously presented its financial statements in Canadian dollars. Under IFRS, the Company's financial 
statements are presented in US 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. 
 
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. 
 
/T/ 
 
The following are outstanding at March 23, 2011: 
Common shares                                                  84,222,987 
Shares issuable on the exercise of warrants                     3,330,686 
Shares issuable on the exercise of outstanding stock options    6,023,555 
 
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. In particular, the development of the Angostura gold-silver project may be materially affected by the 
outcome of the Company's application for an environmental permit with MAVDT. 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.

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. 
 
Management, with the participation of the Chief Executive Officer and the Chief Financial Officer has evaluated 
the design and effectiveness of the Company's disclosure controls and procedures as of December 31, 2010, and 
based upon this evaluation, the CEO and the CFO have concluded that these disclosure controls and procedures, as 
defined by National Instrument 52-109, Certification of Disclosure in Issuers' Annual and Interim Filings, are 
effective for 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. 
 
Management, with the participation of the Chief Executive Officer and the Chief Financial Officer, has conducted 
an evaluation of the design and the effectiveness of the Company's internal control over financial reporting as of 
December 31, 2010 based on Internal Control --Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission. Based on that evaluation, management concluded that the Company's 
internal control over financial reporting, as defined by National Instrument 52-109, Certification of Disclosure 
in Issuers' Annual and Interim Filings, is effective to provide reasonable assurance regarding the reliability of 
financial reporting and the preparation of financial statements in accordance with Canadian GAAP. 
 
There has been no change in the Company's internal control over financial reporting during the year ended December 
31, 2010, 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, success of 
exploration activities, currency fluctuation, the future price of gold and silver, governmental regulation of 
mining operations, and estimated gold recoveries. 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, the outcome of the Company's application for an environmental permit with the MAVDT, 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.
