Summary of Significant Accounting Policies

6 Months Ended

Jun. 30, 2012

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

a. Basis of Preparation

The Company follows accounting standards set by the Financial Accounting Standards Board (FASB). The FASB sets accounting principles generally accepted (GAAP) in the United States that the Company follows to ensure they consistently report their financial condition, results of operations, and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification (ASC) or also referred to as Codification.

These interim consolidated financial statements have been prepared in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries, Aurora Gold Mineração Ltda ("Aurora Gold Mineração") and AGC Resources LLC (“AGC”) (through to date of disposition of AGC, June 14, 2011). Collectively, they are referred to herein as "the Company". Significant inter-company accounts and transactions have been eliminated.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (SEC) rules and regulations. The interim period consolidated financial statements should be read together with the audited consolidated financial statements and accompanying notes included in the Company’s audited consolidated financial statements for the year ended December 31, 2011. In the opinion of the management of the Company, the unaudited consolidated financial statements contained herein contain all adjustments (consisting of a normal recurring nature) necessary to present a fair statement of the results of the interim periods presented.

b. Use of Estimates

The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

c. Cash Equivalents

Cash equivalents comprise certain highly liquid instruments with a maturity date of three months or less when purchased. The Company has cash equivalents of $21,914 and $38,913 at June 30, 2012 and June 30, 2011. Amounts paid for income taxes during the periods ended June 30, 2012 and 2011 were nil; and for interest paid nil respectively.

d. Buildings and Equipment

Buildings and equipment are carried at cost (including development and preproduction costs, capitalized interest, other financing costs and all direct administrative support costs incurred during the construction period, net of cost recoveries and incidental revenues), less accumulated depletion and depreciation including write-downs. Following the construction period, interest, other financing costs and administrative costs are expensed as incurred. On the commencement of commercial production, depletion of each mining property is provided on the unit-of-production basis, using estimated proven and probable reserves as the depletion basis. Buildings and equipment utilized directly in commercial mining activities are depreciated, following the commencement of commercial production, over their expected economic lives using either the unit-of-production method or the straight-line method. Depreciation for non-mining equipment is provided over the following useful lives:

-	Vehicles	10 years
-	Office equipment, furniture and fixtures	2 to 10 years

The Company reviews the carrying values of its buildings and equipment whenever events or changes in circumstances indicate that their carrying values may not be recoverable. An impairment is considered to exist if total estimated future cash flows, or probability-weighted cash flows on an undiscounted basis, are less than the carrying value of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows associated with values beyond proven and probable reserves and resources. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable future cash flows that are largely independent of cash flows from other asset groups. Generally, in estimating future cash flows, all assets are grouped at a particular property for which there are identifiable cash flows. Buildings and equipment utilized directly in commercial mining activities are depreciated, following the commencement of commercial production, over their expected economic lives using either the unit-of-production method or the straight-line method.

e. Mineral Property Reclamation Bonds and Other Related Refundable Costs

Costs paid for the purchase of reclamation bonds and other related costs that are refundable are capitalized.  If amounts paid are not to be refunded then they will be expensed when it is determined they will not be refunded.

f. Mineral Properties and Exploration Expenses

The Company accounts for its mineral properties on a cost basis whereby all direct costs, net of pre-production revenue, relative to the acquisition of the properties are capitalized. All sales and option proceeds received are first credited against the costs of the related property, with any excess credited to earnings. Once commercial production has commenced, the net costs of the applicable property will be charged to operations using the unit-of-production method based on estimated proven and probable recoverable reserves. The net costs related to abandoned properties are charged to operations.

Exploration costs are charged to operations as incurred until such time that proven reserves are discovered. From that time forward, the Company will capitalize all costs to the extent that future cash flow from mineral reserves equals or exceeds the costs deferred. The deferred costs will be amortized over the recoverable reserves when a property reaches commercial production. As at June 30, 2012 and 2011, the Company does not have proven reserves. Exploration activities conducted jointly with others are reflected at the Company's proportionate interest in such activities.

The Company reviews the carrying values of its mineral properties on a regular basis by reference to the project economics including the timing of the exploration or development work, the program of works and the exploration results experienced by the Company and others. The review of the carrying value of any producing property will be made by reference to the estimated future operating results and net cash flows. When the carrying value of a property exceeds its estimated net recoverable amount, provision is made for the decline in value.

The recoverability of the amounts recorded for mineral properties is dependent on the confirmation of economically recoverable reserves, confirmation of the Company’s interest in the underlying mineral claims, the ability of the Company to obtain the necessary financing to successfully complete their development and the attainment of future profitable operations or proceeds from disposal.

Estimated costs related to site restoration programs during the commercial development stage of the property are accrued over the life of the project.

g. Stock-Based Compensation

The Company accounts for share-based payments under the fair value method of accounting for stock-based compensation consistent with GAAP. Under the fair value method, stock-based compensation cost is measured at the grant date based on the fair value of the award using the Black-Sholes option pricing model and is recognized to expense on a straight-line basis over the requisite service period, which is generally the vesting period. Where upon grant the options vest immediately the stock-based costs are expensed immediately.

h. Interest Expense

Interest expense for the periods ended June 30, 2012 and 2011 were nil.

i. Foreign Currency Translation and Transactions

The Company's reporting currency is the United States Dollar (USD). Aurora Gold Mineração Ltda is a foreign operation and its functional currency is the Brazilian Real (Real). Certain contractual obligations in these consolidated financial statements are stated in Brazilian Real’s. At the periods ended June 30, 2012 and 2011 the Brazilian Real exchange rate to the USD was $0.48060 to 1 Real (June 30, 2011: USD $0.63760 to 1 Real).

The Company translates foreign assets and liabilities of its subsidiaries, other than those denominated in USD, at the rate of exchange at the balance sheet date. Income and expenses of these subsidiaries are translated at the average rate of exchange throughout the reporting period. Gains or losses from these translations are reported as a separate component of other comprehensive income (loss) until all or a part of the investment in the subsidiaries is sold or liquidated. The translation adjustments do not recognize the effect of income tax because the Company expects to reinvest the amounts indefinitely in operations.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in foreign exchange (gain) loss in the consolidated statements of operations.

j. Concentration of Credit Risk

Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents.   The Company places its cash with high credit quality financial institutions in Brazil and Canada. The Company occasionally has cash deposits in excess of federally insured limits.  The Company had funds deposited in banks beyond the insured limits as of June 30, 2012 and 2011 respectively. The Company has not experienced any losses related to these balances, and management believes the credit risk to be minimal.

k. Fair Value of Financial Instruments and Risks

Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair value. The carrying value of cash, accounts payable, accrued expenses and advances payable (including related parties) approximate their fair value because of the short-term nature of these instruments.

Management is of the opinion that the Company is not exposed to significant interest or credit risks arising from these financial instruments. The Company operates outside of the United States of America (primarily in Brazil) and is exposed to foreign currency risk due to the fluctuation between the currency in which the Company operates in and the USD.

l. Income Taxes

The Company has adopted ASC 740, Accounting for Income Taxes, which requires the Company to recognize deferred tax liabilities and assets for the expected future tax consequences of events that have been recognized in the Company's financial statements or tax returns using the liability method. Under this method, deferred tax liabilities and assets are determined based on the differences between the financial statement carrying amounts and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. In July 2006, the FASB issued an interpretation, which clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements in accordance with GAAP. This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Estimated interest and penalties related to recording uncertain tax positions when recorded are included as a component of income tax expense on the consolidated statement of operations. The Company has not recorded any liabilities for uncertain tax positions or any related interest and penalties. The Company’s tax returns are open to audit for the years ending December 31, 2008 to 2011 respectively.

m. Basic and Diluted Net Income (Loss) Per Share

Earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the reporting period including common stock issued effective the date committed. Common stock issuable is considered outstanding as of the original approval date for the purposes of earnings per share computations. Diluted earnings (loss) per common share is computed by dividing net earnings (loss) by the sum of (a) the basic weighted average number of shares of common stock outstanding during the period and (b) additional shares that would have been issued and potentially dilutive securities. During the six months ended June 30, 2012 and 2011 the diluted earnings (loss) per share was equivalent to the basic earnings (loss) per share because all potentially dilutive securities were anti-dilutive due to the net losses incurred. Potentially dilutive securities consist of stock options and warrants outstanding at the end of the reporting period. Stock options outstanding as at June 30, 2012 were 10,650,000 (2011:1,700,000). Warrants outstanding as at June 30, 2012 were 8,000,000 (2011:nil).

n. Interim Financial Statements

In the opinion of management, the accompanying unaudited condensed financial statements contain all adjustments which include only normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods shown. The results of operations for such periods are not necessarily indicative of the results expected for a full year or for any future period.

The unaudited financial statements should be read in conjunction with the Company’s audited financial statements and notes for the year ended December 31, 2011, which are included in the Company’s Annual Report on Form 10-K.

o. Recent Accounting Pronouncements

The Company considers the effects of new accounting pronouncements on the accounting, presentation and disclosure of its consolidated financial statements, as such pronouncements become known. In June 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-05, Comprehensive Income or ASU 2011-05. The guidance in ASU 2011-05 revises the manner in which entities present comprehensive income in their financial statements. An entity is required to report the components of comprehensive income in either one or two consecutive financial statements:

-         A single, continuous statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income.

-         In a two-statement approach, an entity must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income.

ASU 2011-05 does not change the items that must be reported in other comprehensive income. The amendments in ASU 2011-05 are effective for fiscal years beginning after December 15, 2011 and the Company adopted this guidance effective January 1, 2012. In the consolidated statements of comprehensive income (loss) the Company has presented comprehensive income in a single continuous statement.

At present, there are no other such pronouncements not yet effective that the Company expects will have a material impact on these consolidated financial statements.

Organization, Nature of Business, Going Concern and Management's Plans

1. Organization, Nature of Business, Going Concern and Management’s Plans

Aurora Gold Corporation ("the Company") was formed on October 10, 1995 under the laws of the State of Delaware and is in the business of location, acquisition, exploration and, if warranted, development of mineral properties. The Company’s focus is on the exploration and development of its exploration properties located in the Tapajos Gold Province, State of Pará, Brazil (see Note 3). The Company has not yet determined whether its properties contain mineral reserves that may be economically recoverable and has not generated any operating revenues to date.

These interim consolidated financial statements have been prepared in accordance with generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The general business strategy of the Company is to acquire mineral properties either directly or through the acquisition of operating entities. The Company has incurred recurring operating losses since inception, has not generated any operating revenues to date and during the period ended June 30, 2012, operating activities used cash of $313,682 (June 30, 2011: $833,983). The Company requires additional funds to meet its obligations and maintain its operations.

These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in this regard are to raise equity financing through private or public equity investment in order to support existing operations and expand its business. The Company currently has a Prospectus out on offer and these details are included in further detail in these notes. There is however no assurance that such additional funding will be available to the Company when required, or on terms acceptable to the Company. In the event that the Company cannot obtain additional funds, on a timely basis, or the operations do not generate sufficient cash flow, the Company may be forced to curtail development or cease activities.

Summary of Significant Accounting Policies (Policies)

6 Months Ended

Jun. 30, 2012

Basis of Preparation

a. Basis of Preparation

The Company follows accounting standards set by the Financial Accounting Standards Board (FASB). The FASB sets accounting principles generally accepted (GAAP) in the United States that the Company follows to ensure they consistently report their financial condition, results of operations, and cash flows. References to GAAP issued by the FASB in these footnotes are to the FASB Accounting Standards Codification (ASC) or also referred to as Codification.

These interim consolidated financial statements have been prepared in accordance with GAAP and include the accounts of the Company and its wholly owned subsidiaries, Aurora Gold Mineração Ltda ("Aurora Gold Mineração") and AGC Resources LLC (“AGC”) (through to date of disposition of AGC, June 14, 2011). Collectively, they are referred to herein as "the Company". Significant inter-company accounts and transactions have been eliminated.

Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such Securities and Exchange Commission (SEC) rules and regulations. The interim period consolidated financial statements should be read together with the audited consolidated financial statements and accompanying notes included in the Company’s audited consolidated financial statements for the year ended December 31, 2011. In the opinion of the management of the Company, the unaudited consolidated financial statements contained herein contain all adjustments (consisting of a normal recurring nature) necessary to present a fair statement of the results of the interim periods presented.

Use of Estimates

b. Use of Estimates

The preparation of financial statements in conformity with GAAP 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 revenues and expenses during the reporting period. Actual results could differ from those estimates and assumptions.

Cash Equivalents

c. Cash Equivalents

Cash equivalents comprise certain highly liquid instruments with a maturity date of three months or less when purchased. The Company has cash equivalents of $21,914 and $38,913 at June 30, 2012 and June 30, 2011. Amounts paid for income taxes during the periods ended June 30, 2012 and 2011 were nil; and for interest paid nil respectively.

Buildings and Equipment

d. Buildings and Equipment

Buildings and equipment are carried at cost (including development and preproduction costs, capitalized interest, other financing costs and all direct administrative support costs incurred during the construction period, net of cost recoveries and incidental revenues), less accumulated depletion and depreciation including write-downs. Following the construction period, interest, other financing costs and administrative costs are expensed as incurred. On the commencement of commercial production, depletion of each mining property is provided on the unit-of-production basis, using estimated proven and probable reserves as the depletion basis. Buildings and equipment utilized directly in commercial mining activities are depreciated, following the commencement of commercial production, over their expected economic lives using either the unit-of-production method or the straight-line method. Depreciation for non-mining equipment is provided over the following useful lives:

-	Vehicles	10 years
-	Office equipment, furniture and fixtures	2 to 10 years

The Company reviews the carrying values of its buildings and equipment whenever events or changes in circumstances indicate that their carrying values may not be recoverable. An impairment is considered to exist if total estimated future cash flows, or probability-weighted cash flows on an undiscounted basis, are less than the carrying value of the assets. An impairment loss is measured and recorded based on discounted estimated future cash flows associated with values beyond proven and probable reserves and resources. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable future cash flows that are largely independent of cash flows from other asset groups. Generally, in estimating future cash flows, all assets are grouped at a particular property for which there are identifiable cash flows. Buildings and equipment utilized directly in commercial mining activities are depreciated, following the commencement of commercial production, over their expected economic lives using either the unit-of-production method or the straight-line method.

Mineral Property Reclamation Bonds and Other Related Refundable Costs

e. Mineral Property Reclamation Bonds and Other Related Refundable Costs

Costs paid for the purchase of reclamation bonds and other related costs that are refundable are capitalized.  If amounts paid are not to be refunded then they will be expensed when it is determined they will not be refunded.

Mineral Properties and Exploration Expenses

f. Mineral Properties and Exploration Expenses

The Company accounts for its mineral properties on a cost basis whereby all direct costs, net of pre-production revenue, relative to the acquisition of the properties are capitalized. All sales and option proceeds received are first credited against the costs of the related property, with any excess credited to earnings. Once commercial production has commenced, the net costs of the applicable property will be charged to operations using the unit-of-production method based on estimated proven and probable recoverable reserves. The net costs related to abandoned properties are charged to operations.

Exploration costs are charged to operations as incurred until such time that proven reserves are discovered. From that time forward, the Company will capitalize all costs to the extent that future cash flow from mineral reserves equals or exceeds the costs deferred. The deferred costs will be amortized over the recoverable reserves when a property reaches commercial production. As at June 30, 2012 and 2011, the Company does not have proven reserves. Exploration activities conducted jointly with others are reflected at the Company's proportionate interest in such activities.

The Company reviews the carrying values of its mineral properties on a regular basis by reference to the project economics including the timing of the exploration or development work, the program of works and the exploration results experienced by the Company and others. The review of the carrying value of any producing property will be made by reference to the estimated future operating results and net cash flows. When the carrying value of a property exceeds its estimated net recoverable amount, provision is made for the decline in value.

The recoverability of the amounts recorded for mineral properties is dependent on the confirmation of economically recoverable reserves, confirmation of the Company’s interest in the underlying mineral claims, the ability of the Company to obtain the necessary financing to successfully complete their development and the attainment of future profitable operations or proceeds from disposal.

Estimated costs related to site restoration programs during the commercial development stage of the property are accrued over the life of the project.

Stock-Based Compensation

g. Stock-Based Compensation

The Company accounts for share-based payments under the fair value method of accounting for stock-based compensation consistent with GAAP. Under the fair value method, stock-based compensation cost is measured at the grant date based on the fair value of the award using the Black-Sholes option pricing model and is recognized to expense on a straight-line basis over the requisite service period, which is generally the vesting period. Where upon grant the options vest immediately the stock-based costs are expensed immediately.

Interest Expense

h. Interest Expense

Interest expense for the periods ended June 30, 2012 and 2011 were nil.

Foreign Currency Translation and Transactions

i. Foreign Currency Translation and Transactions

The Company's reporting currency is the United States Dollar (USD). Aurora Gold Mineração Ltda is a foreign operation and its functional currency is the Brazilian Real (Real). Certain contractual obligations in these consolidated financial statements are stated in Brazilian Real’s. At the periods ended June 30, 2012 and 2011 the Brazilian Real exchange rate to the USD was $0.48060 to 1 Real (June 30, 2011: USD $0.63760 to 1 Real).

The Company translates foreign assets and liabilities of its subsidiaries, other than those denominated in USD, at the rate of exchange at the balance sheet date. Income and expenses of these subsidiaries are translated at the average rate of exchange throughout the reporting period. Gains or losses from these translations are reported as a separate component of other comprehensive income (loss) until all or a part of the investment in the subsidiaries is sold or liquidated. The translation adjustments do not recognize the effect of income tax because the Company expects to reinvest the amounts indefinitely in operations.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are included in foreign exchange (gain) loss in the consolidated statements of operations.

Concentration of Credit Risk

j. Concentration of Credit Risk

Financial instruments that subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents.   The Company places its cash with high credit quality financial institutions in Brazil and Canada. The Company occasionally has cash deposits in excess of federally insured limits.  The Company had funds deposited in banks beyond the insured limits as of June 30, 2012 and 2011 respectively. The Company has not experienced any losses related to these balances, and management believes the credit risk to be minimal.

Fair Value of Financial Instruments and Risks

k. Fair Value of Financial Instruments and Risks

Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair value. The carrying value of cash, accounts payable, accrued expenses and advances payable (including related parties) approximate their fair value because of the short-term nature of these instruments.

Management is of the opinion that the Company is not exposed to significant interest or credit risks arising from these financial instruments. The Company operates outside of the United States of America (primarily in Brazil) and is exposed to foreign currency risk due to the fluctuation between the currency in which the Company operates in and the USD.

Income Taxes

l. Income Taxes

The Company has adopted ASC 740, Accounting for Income Taxes, which requires the Company to recognize deferred tax liabilities and assets for the expected future tax consequences of events that have been recognized in the Company's financial statements or tax returns using the liability method. Under this method, deferred tax liabilities and assets are determined based on the differences between the financial statement carrying amounts and tax bases of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. In July 2006, the FASB issued an interpretation, which clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements in accordance with GAAP. This interpretation prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. Estimated interest and penalties related to recording uncertain tax positions when recorded are included as a component of income tax expense on the consolidated statement of operations. The Company has not recorded any liabilities for uncertain tax positions or any related interest and penalties. The Company’s tax returns are open to audit for the years ending December 31, 2008 to 2011 respectively.

Basic and Diluted Net Income (Loss) Per Share

m. Basic and Diluted Net Income (Loss) Per Share

Earnings (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the reporting period including common stock issued effective the date committed. Common stock issuable is considered outstanding as of the original approval date for the purposes of earnings per share computations. Diluted earnings (loss) per common share is computed by dividing net earnings (loss) by the sum of (a) the basic weighted average number of shares of common stock outstanding during the period and (b) additional shares that would have been issued and potentially dilutive securities. During the six months ended June 30, 2012 and 2011 the diluted earnings (loss) per share was equivalent to the basic earnings (loss) per share because all potentially dilutive securities were anti-dilutive due to the net losses incurred. Potentially dilutive securities consist of stock options and warrants outstanding at the end of the reporting period. Stock options outstanding as at June 30, 2012 were 10,650,000 (2011:1,700,000). Warrants outstanding as at June 30, 2012 were 8,000,000 (2011:nil).

Interim Financial Statements

n. Interim Financial Statements

In the opinion of management, the accompanying unaudited condensed financial statements contain all adjustments which include only normal recurring adjustments, necessary to present fairly the Company’s financial position, results of operations and cash flows for the periods shown. The results of operations for such periods are not necessarily indicative of the results expected for a full year or for any future period.

The unaudited financial statements should be read in conjunction with the Company’s audited financial statements and notes for the year ended December 31, 2011, which are included in the Company’s Annual Report on Form 10-K.

Recent Accounting Pronouncements

o. Recent Accounting Pronouncements

The Company considers the effects of new accounting pronouncements on the accounting, presentation and disclosure of its consolidated financial statements, as such pronouncements become known. In June 2011, the FASB issued Accounting Standards Update ("ASU") No. 2011-05, Comprehensive Income or ASU 2011-05. The guidance in ASU 2011-05 revises the manner in which entities present comprehensive income in their financial statements. An entity is required to report the components of comprehensive income in either one or two consecutive financial statements:

-         A single, continuous statement must present the components of net income and total net income, the components of other comprehensive income and total other comprehensive income, and a total for comprehensive income.

-         In a two-statement approach, an entity must present the components of net income and total net income in the first statement. That statement must be immediately followed by a financial statement that presents the components of other comprehensive income, a total for other comprehensive income, and a total for comprehensive income.

ASU 2011-05 does not change the items that must be reported in other comprehensive income. The amendments in ASU 2011-05 are effective for fiscal years beginning after December 15, 2011 and the Company adopted this guidance effective January 1, 2012. In the consolidated statements of comprehensive income (loss) the Company has presented comprehensive income in a single continuous statement.

At present, there are no other such pronouncements not yet effective that the Company expects will have a material impact on these consolidated financial statements.

Stock Options

6. Stock Options

In 2007, the Company's Board of Directors approved the 2007 Stock Option Plan (amended September 29, 2008) (“the Plan”) to offer an incentive to obtain services of key employees, directors and consultants of the Company. The Plan provides for the reservation for awards of an aggregate of 10% of the total shares of Common Stock outstanding from time to time. No Plan participant may receive stock options exercisable for more than 2,500,000 shares of Common Stock in any one calendar year. Under the Plan, the exercise price of an incentive stock option must be at least equal to 100% of the fair market value of the common stock on the date of grant (110% of fair market value in the case of options granted to employees who hold more than 10% of the Company's capital stock on the date of grant). The term of stock options granted under the Plan is not to exceed ten years and the stock options vest immediately upon granting.

The following is a summary of stock option activity and the status of stock options outstanding and exercisable at June 30, 2012:

	Stock  Options   #			Weighted  Average Exercise Price $		Remaining Contractual  Life (years)  As At		Aggregate  Intrinsic value   As At
Outstanding and exercisable at December 31, 2011		9,050,000			0.110		4.28		36,500
Forfeited during March 31, 2012		(200,000	)		0.260		-		-
Granted during March 31, 2012		1,600,000			0.050		-		-
Outstanding and exercisable at March, 31, 2012		10,450,000			0.090		4.21		42,000
Granted during June 30, 2012		200,000			0.065		-		-
Outstanding and exercisable at June, 30, 2012		10,650,000			0.097		3.97		34,125

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value for all “in-the-money” options (i.e. the difference between the Company’s closing stock price on the last trading day of the fiscal year and the exercise price, multiplied by the number of shares) that would have been received by the option holders had all option holders exercised their options on June 30, 2012.

Effective April 10, 2012, the Company’s board of directors granted 200,000 stock purchase options pursuant to the Company’s 2007 Stock Option Plan. Each of the Options has an issue date, effective date and vesting date of April 10, 2012, with an exercise price of $0.065 per share. The term of these Options are five years. The Options are exercisable at any time from the grant date up to and including April 9, 2017.

During the quarter ended March 31, 2012, Cameron Richardson departed the Company, an exercise notice for the 200,000 options held was not lodged and consequently the options lapsed during the quarter.

Effective January 13, 2012, the Company’s board of directors granted 1,600,000 stock purchase options pursuant to the Company’s 2007 Stock Option Plan. Each of the Options has an issue date, effective date and vesting date of January 13, 2012, with an exercise price of $0.05 per share. The term of these Options are five years. The Options are exercisable at any time from the grant date up to and including January 12, 2017.

Effective November 24, 2011, the Company’s board of directors granted 3,650,000 stock purchase options pursuant to the Company’s 2007 Stock Option Plan. Each of the Options has an issue date, effective date and vesting date of November 24, 2011, with an exercise price of $0.05 per share. The term of these Options are five years. The Options are exercisable at any time from the grant date up to and including November 23, 2016.

Effective October 11, 2011, the Company’s board of directors granted 4,200,000 stock purchase options pursuant to the Company’s 2007 Stock Option Plan. Each of the Options has an issue date, effective date and vesting date of October 11, 2011, with an exercise price of $0.12 per share. The term of these Options are five years. The Options are exercisable at any time from the grant date up to and including October 10, 2016.

On June 15, 2011 Michael Montgomery resigned from the board of directors, an exercise notice for the 500,000 options held was not lodged and consequently the options lapsed on July 15, 2011.

The total fair value of options granted during the three months ended June 30, 2012 was $11,979 (June 30, 2011: nil) and expensed in full as options were vested in full on grant. The fair value of options are determined using the Black Scholes option pricing model that takes into account the exercise price, the expected life of the option, the share price at grant date (April 10, 2012) and expected price volatility of the underlying share, the expected dividend yield (nil assumed) and the risk free interest rate (4.50% used) for the term of the option. Management determined 2.50 years to be the average expected likely life of the options and utilized the simplified method due to the fact that the Company has not had significant options granted to develop historical data to provide a reasonable basis to estimate option lives. Volatility rates were calculated at the grant date of the option tranche and a rate of 161.04% was used. As of June 30, 2012, there are outstanding Warrants to purchase 8,000,000 shares of common stock with an exercise price of $0.08 expiring June 20, 2013.

The total fair value of options granted for the three months ended March 31, 2012 was $43,681 (March 31, 2011: nil) and expensed in full as options were vested in full on grant. The fair value of options are determined using the Black Scholes option pricing model that takes into account the exercise price, the expected life of the option, the share price at grant date (January 13, 2012) and expected price volatility of the underlying share, the expected dividend yield (nil assumed) and the risk free interest rate (4.50% used) for the term of the option. Management determined 2.50 years to be the average expected likely life of the options and utilized the simplified method due to the fact that the Company has not had significant options granted to develop historical data to provide a reasonable basis to estimate option lives. Volatility rates were calculated at the grant date of the option tranche and a rate of 120.89% was used.

3. Mineral Properties and Exploration Expenses

(a) São Domingos Project in the Municipality of Itaituba, in the Tapajos gold province of the State of Para, Brazil, Department of National Production Minerals (DNPM) Processes 850.684/06 and 850.782/05:

i. DNPM Processes 850.684/06:

Aurora has good title over the mineral rights, which were granted as DNPM Process number 850.684/06 and which is valid and in force, free and clear of any judicial and extrajudicial encumbrances and taxes. The São Domingos mineral rights are located at the Municipality of Itaituba, State of Pará, and are registered in the name of Aurora. On September 13, 2006 the Company applied to the DNPM for the conversion of the Application to an Exploration Permit covering an area of 4,914.18 hectares. No payments or royalties are due regarding DNPM Process 850.384/06.

ii. DNPM Processes 850.782/05:

Aurora has good title over the mineral rights object of the DNPM Process No. 850.782/05, which is valid and in force, free and clear of any judicial and extrajudicial encumbrances and taxes. On November 8, 2005 it was submitted to DNPM the Exploration Claim for gold in the Municipality of Itaituba, State of Pará. The Exploration Permit was granted on November 28, 2006 for a three-year period. The transfer to Aurora was approved on March 24, 2009 and on September 28, 2009 it was requested the renewal of the Exploration Permit. This area was reduced from 6,756 hectares to 5,651.98 hectares due to the overlapping with Garimpeira (alluvial) Mining properties held by Mr Celio Paranhos. However the DNPM´s general attorney in Brasilia agreed with Aurora’s legal thesis and nullified all applications filed by Mr Paranhos (about to 1,900 applications). A new Exploration Permit rectifying the previous one was granted on August 20, 2010 for a three-year period, for an area of 6,656.20 hectares. No payments or royalties are due regarding the DNPM Process 850.782/05 since it was acquired through a permutation agreement with Altoro Mineração Ltda.

iii. DNPM Processes 850.012/06 and 850.013/06:

The exploration claims were submitted to DNPM on January 19, 2006, for gold covering an area of 1,128.08 hectares and 750.55 hectares respectively, in the Municipality of Itaituba, State of Pará. According to information obtained such claims were correctly prepared and the required documents are in place. The tenements 850.012/06 and 850.013/06 are held by Mr Antonio Oliveira Ferreira and were submitted to DNPM on January 19, 2006. The tenements are located at Itaituba, State of Pará and are valid and in force, free and clear of any judicial and extrajudicial encumbrances and taxes, but the area was blocked since it is inside of a Garimpeira Reserve. The transfer to Aurora will be submitted after the Exploration Permits are granted. There are no payments or royalties related to the tenements according to the agreement entered into with the previous owner.

iv. DNPM Process 850.119/06:

The exploration claim was submitted to DNPM on March 7, 2006, for gold covering an area of 1,068.72 hectares, in the Municipality of Itaituba, State of Pará. Aurora has good title over the mineral rights object of the DNPM Process No. 850.119/06, which is valid and in force, free and clear of any judicial and extrajudicial encumbrances and taxes. Aurora is the sole registered and beneficial holder of and owns and possesses good title to the referred mineral rights. The Exploration Permit has not been granted yet. The above-mentioned area is not related to any payments or royalties to third parties since Aurora claimed them directly.

v. DNPM Process 859.587/95:

The tenement, was held by Vera Lucia Lopes, and is valid and in force, and is free and clear of any judicial and extrajudicial encumbrances and taxes. It is located at the Municipality of Itaituba, State of Pará. On November 27, 1995, it was submitted to DNPM the Exploration Claim for gold.

On July 15, 2009, it was requested the renewal of the Exploration Permit which was granted and transferred to Aurora and published on June 29, 2012.

On June 10, 2008 it was presented an appeal to have the annulment dismissed, which hasn’t been analyzed yet. However, if the appeal is not approved, Samba Brazil’s rights over this tenement are guaranteed since only Samba Brazil has presented a Bid application for this process on July 18 2008. According to the Agreement signed between Samba Brazil and Antonio Oliveira Ferreira on June 5, 2008, a total amount of 120,000 Brazilian Real’s has already been paid by Samba Brazil for the acquisition of the Tenements.

(c) British Columbia, Canada – Kumealon Property (relinquished)

On January 20, 2012 the Company’s Kumealon claim over the property was relinquished.

(d) Sale of AGC Resources

On June 14, 2011, the Company, entered into an Asset Purchase Agreement with Devtec Management Ltd. (“Devtec”), pursuant to which the Company sold its subsidiary, AGC, which owns certain properties in Boulder, Colorado (see note 3(b) for a discussion of the specific assets purchased by AGC in June 2010), to Devtec for a total of $2 million, plus royalty. Under the terms of the agreement, Devtec will pay the Company $1 million upon production of the cumulative total of 1,000 ounces of gold and/or silver, and a further $1 million on the six month anniversary of the payment of the first $ 1 million. Additionally, Devtec will pay the Company a 5% royalty from the start of production.

The Company was unable to reasonably estimate the amount of minerals the properties will produce, if any, and thus there was uncertainty as to whether the purchase price will be collected. Given this, collection of the purchase price is not considered reasonably possible at the time of these consolidated financial statements given the current uncertain status of exploration work on the Boulder ,Colorado properties and thus no purchase price has been recorded as of June 30, 2011. Therefore, the Company recognized a loss on the sale of its subsidiary of $2,512,290 for the three and six months ended June 30, 2011, which represented the net book value of the assets transferred to Devtec on June 14, 2011 (no liabilities were assumed by Devtec) as follows:
