Principal Accounting Policies [Abstract]	'
Principal Accounting Policies	'
	1	Principal Accounting Policies:
	Paramount Gold and Silver Corp. (the “Company”), incorporated under the General Corporation Law of the State of Delaware, and its wholly-owned subsidiaries are engaged in the acquisition, exploration and development of precious metal properties. The Company’s wholly owned subsidiaries include Paramount Gold de Mexico S.A. de C.V., Magnetic Resources Ltd, Minera Gama SA de CV, and X-Cal Resources Ltd. The Company is in the process of exploring its mineral properties in both the United States and Mexico. The Company’s activities are subject to significant risks and uncertainties, including failing to secure additional funding to advance its projects and to date has not determined whether these properties contain reserves that are economically recoverable.
	Basis of Presentation and Preparation
	The consolidated financial statements are prepared by management in accordance with U.S generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
	Use of Estimates
	The preparation of consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	Significant estimates made by management in the accompanying financial statements include collectability of amounts receivable, the adequacy of the Company’s asset retirement obligations, fair value of stock based compensation and valuation of deferred tax assets.
	Cash and Cash Equivalents
	All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash and cash equivalents.
	Marketable Securities
	The Company classifies its marketable securities as available-for-sale securities. The securities are measured at fair market value in the financial statements with unrealized gains and temporary losses on investments classified as available for sale are included within accumulated other comprehensive income, net of any related tax effect. Upon realization, such amounts are reclassified from accumulated other comprehensive income to other income, net, realized gains and losses and other than temporary impairments, if any, are reflected in the statements of operations as other income or expenses. The Company does not recognize changes in the fair value of its investments in income unless a decline in value is considered other than temporary.
	Fair Value Measurements
	The Company has adopted FASB ASC 820, Fair Value Measurements and Disclosures, which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. The Company applies fair value accounting for all financial assets and liabilities and non – financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
	The Company has adopted FASB ASC 825, Financial Instruments, which allows companies to choose to measure eligible financial instruments and certain other items at fair value that are not required to be measured at fair value. The Company has not elected the fair value option for any eligible financial instruments.
	Stock Based Compensation
	The Company has adopted the provisions of FASB ASC 718, “Stock Compensation” (“ASC 718”), which establishes accounting for equity instruments exchanged for employee services. Under the provisions of ASC 718, stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity grant). New shares of the Company’s Common Stock will be issued for any options exercised or awards granted.
	Comprehensive Income
	FASB ASC 220“Reporting Comprehensive Income” establishes standards for the reporting and display of comprehensive income and its components in the financial statements.
	Mineral Properties
	Mineral property acquisition costs are capitalized when incurred and will be amortized using the units –of – production method over the estimated life of the reserve following the commencement of production. If a mineral property is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment.
	Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of mineral properties.
	Exploration Costs
	Exploration costs, which include maintenance, development and exploration of mineral claims, are expensed as incurred. When it is determined that a mineral deposit can be economically developed as a result of establishing proven and probable reserves, the costs incurred after such determination will be capitalized and amortized over their useful lives. To date, the Company has not established the commercial feasibility of its exploration prospects; therefore, all exploration costs are being expensed.
	Derivatives
	The Company accounts for its derivative instruments not indexed to our stock as either assets or liabilities and carries them at fair value. Derivatives that are not defined as hedges must be adjusted to fair value through earnings.
	Warrants and options issued and outstanding in prior periods with exercise prices denominated in Canadian dollars were not considered indexed to our stock, as their exercise price was not in the Company’s functional currency of the US dollar, and therefore no longer qualified for the scope exception and were accounted for as a derivative. These warrants and options were reclassified as liabilities under the caption “Warrant liability” and recorded at estimated fair value at each reporting date, computed using the Black-Scholes valuation method. Changes in the liability from period to period were recorded in the Statements of Operations under the caption “Change in fair value of warrant liability.”
	The Company elected to record the change in fair value of the warrant liability as a component of other income and expense on the statement of operations as we believe the amounts recorded relate to financing activities and not as a result of our operations.
	Property and Equipment
	Equipment is recorded at cost less accumulated depreciation. All equipment is amortized over its estimated useful life at the following annual rates:
	Computer equipment	30% declining balance
	Equipment	20% declining balance
	Furniture and fixtures	20% declining balance
	Exploration equipment	20% declining balance
	Income Taxes
	Income taxes are determined using assets and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. In addition, a valuation allowance is established to reduce any deferred tax asset for which it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.
	Potential benefits of income tax losses are not recognized in the accounts until realization is more likely than not. The Company has adopted FASB ASC 740 as of its inception. Pursuant to FASB ASC 740 the Company is required to compute tax asset benefits for net operating losses carried forward. Potential benefits of net operating losses have not been recognized in these financial statements because the Company cannot be assured it is more likely than not it will utilize the net operating losses carried forward in future periods; and accordingly is offset by a valuation allowance. FIN No.48 prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of tax positions taken in tax returns.
	To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, such amounts would be accrued and classified as a component of income tax expense in our Consolidated Statements of Operations and Comprehensive Loss. The Company elected this accounting policy, which is a continuation of our historical policy, in connection with our adoption of FIN 48.
	Net Income (Loss) Per Share
	Basic earnings(loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of shares outstanding during each period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
	For the years ended June 30, 2014, 2013 and 2012 the shares of common stock equivalents related to outstanding stock option and stock purchase warrants have not been included in the diluted per share calculation as they are anti-dilutive as the Company has recorded a net loss from continuing operations for each year.
	Revenue Recognition
	Revenue is recognized when persuasive evidence that an agreement exists, the risks and rewards of ownership pass to the purchaser, the selling price is fixed and determinable; or collection is reasonably assured. The passing of title to the purchaser is based on the terms of the purchase and sale agreement.
	Concentration of Credit Risk and Amounts Receivable
	Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents and amounts receivable. The Company maintains cash in accounts which may, at times, exceed federally insured limits. At June 30, 2014, the balances of approximately $4.8 million were in excess of federally insured limits. We deposit our cash with financial institutions which we believe have sufficient credit quality to minimize the risk of loss.
	Impuesto al Valor Agregado taxes (IVA) are recoverable value-added taxes charged by the Mexican government on goods sold and services rendered at a rate of 16%. Under certain circumstances, these taxes are recoverable by filing a tax return and as determined by the Mexican taxing authority. Each period, receivables are reviewed for collectability. When a receivable is determined to not be collectable we allow for the receivable until we are either assured of collection or assured that a write-off is necessary. Allowances in association with our receivable from IVA from our Mexico subsidiaries is based on our determination that the Mexican government may not allow the complete refund of these taxes. The Company believes that all amounts recorded as a receivable from the Mexican government will be recovered.
	Foreign Currency
	The parent company’s functional currency is the United States dollar. The functional currencies of the Company’s wholly-owned subsidiaries are the U.S. Dollar and the Canadian Dollar. Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate prevailing at the consolidated balance sheet date. Foreign currency transaction gains and losses are included in the statement of operations and comprehensive loss. The aggregate foreign transaction loss for the year ended June 30, 2014 is $41,168.
	The financial statements of the subsidiaries are translated to United States dollars in accordance with ASC 830 using period-end rates of exchange for assets and liabilities, and average rates of exchange for the period for revenues and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity.

	2	Recent Accounting Pronouncements Adopted:
	Accounting Pronouncements Adopted During the Period
	i)	ASU 2014-10
	In June 2014, the FASB issued ASU 2014-10, “Development Stage Entities (Topic 915)”. The amendments in ASU 2014-10 remove all incremental financial reporting requirements from U.S. GAAP for development stage entities, including the removal of Topic 915, Development Stage Entities, from the FASB Accounting Standards Codification. In addition, the ASU: (a) adds an example disclosure in Topic 275, Risks and Uncertainties, to illustrate one way that an entity that has not begun planned principal operations could provide information about the risks and uncertainties related to the company’s current activities; and (b) removes an exception provided to development stage entities in Topic 810, Consolidation, for determining whether an entity is a variable interest entity. The presentation and disclosure requirements in Topic 915 will no longer be required for the first annual reporting period beginning after December 15, 2014. The withdrawal of the presentation and disclosure requirements of Topic 915 is effective for annual reporting periods beginning after December 15, 2015. The revised consolidation standards are effective for annual reporting periods beginning after December 15, 2016. Early adoption is permitted for any annual reporting period or interim period for which an entity’s financial statements have not yet been issued or made available for issuance. The Company has early adopted ASU 2014-10 and impacts of its adoption have been reflected throughout the Company’s consolidated financial statements, with the significant effect being the elimination of disclosures of certain cumulative amounts incurred during the period from inception to the period end reporting date.
	New Accounting Pronouncements Not Yet Adopted
	i)	ASU 2013-05
	In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-05, “Foreign Currency Matters (Topic 830); Parents Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” This guidance applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business (other than a sale of substance real estate or conveyance of oil and gas, mineral rights) within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods with those years) beginning after December 15, 2013. We are currently reviewing the provisions of ASU No. 2013-05 on our financial position or results of operations.
	ii)	ASU 2013-11
	In July 2013, FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exits.” The FASB’s objective in issuing this ASU is to eliminate diversity in practice resulting from a lack of guidance on this topic in current U.S. GAAP. This ASU applies to all entities with unrecognized tax benefits that also have tax loss or tax credit carryforwards in the same tax jurisdiction as of the reporting date. ASU No. 2013-11 is effective for public entities for fiscal years beginning after December 15, 2013, and interim periods within those years. Early adoption is permitted. The amendments should be applied to all unrecognized tax benefits that exist as of the effective date. Entities may choose to apply the amendments retrospectively to each prior reporting period presented. We are currently assessing the impact of the adoption of this update on our financial position or results of operations.

Fair Value Measurements [Abstract]	'
Fair Value Measurements	'
	4	Fair Value Measurements:
	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated by applying the following hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization with the hierarchy upon the lowest level of input that is available and significant to the fair value measurement:
	The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3).
	The three levels of the fair value hierarchy under ASC 820 are described below:
	Level 1	Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
	Level 2	Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.
	Level 3	Inputs that are both significant to the fair value measurement and unobservable.
	The following table sets forth the Company’s financial assets and liabilities measured at fair value by level within the fair value hierarchy. As required by ASC 820, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.
			Fair Value at June 30, 2014								30-Jun-13
	Assets		Total		Level 1		Level 2		Level 3		Total
	Cash and cash equivalents		$	5,107,691	$	5,107,691	$	-	$	-	$	11,524,051
	Marketable Securities		$	560,099	$	-	$	-	$	560,099	$	450,000
	The Company’s cash and cash equivalents and short-term investments are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The cash and cash equivalents that are valued based on quoted market prices in active markets are primarily comprised of commercial paper, short-term certificates of deposit and U.S. Treasury securities.
	The Company’s marketable securities include convertible preferred stock and stock purchase warrants. The convertible preferred stock is recorded at fair market value in the financial statements based on quoted market prices of the underlying common stock security with an adjustment made using a European put option model to reflect certain restrictions from resale. The stock purchase warrants’ fair value is recorded using a Black Scholes options model using inputs such as contractual terms, stock volatility and implied interest rates. The Company’s marketable securities are classified within Level 3 of the fair value hierarchy.

	Stock Based Compensation
	The Company uses the Black-Scholes option valuation model to value stock options granted. The Black-Scholes model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The model requires management to make estimates which are subjective and may not be representative of actual results. Changes in assumptions can materially affect estimates of fair values. For purposes of the calculation, the following assumptions were used:
		30-Jun-14	30-Jun-13
	WA Risk free interest rate	0.12%	0.15%
	WA Expected dividend yield	0%	0%
	WA Expected stock price volatility	58%	64%
	WA Expected life of options	2 years	2.9 years
	Changes in the Company’s stock options for the year ended June 30, 2014 are summarized below:

	11	Reclamation and Environmental:
	The Company holds an insurance policy related to its Sleeper Gold Project that covers reclamation costs in the event the Company defaults on payments of its reclamation costs up to an aggregate of $25 million. The insurance premium is being amortized over ten years and the current and non-current prepaid insurance balance at June 30, 2014 is $122,607 (2013 - $367,822).
	As a part of the policy, the Company has funds in a commutation account which is used to reimburse reclamation costs and indemnity claims. The balance of the commutation account at June 30, 2014 is $2,626,538 (2013 - $2,718,384).
	Reclamation and environmental costs are based principally on legal requirements. Management estimates costs associated with reclamation of mineral properties and properties under mine closure. On an ongoing basis the Company evaluates its estimates and assumptions; however, actual amounts could differ from those based on estimates and assumptions.
	The asset retirement obligation at the Sleeper Gold Project has been measured using the following variables: 1)Expected costs for earthwork, re-vegetation, in-pit water treatment, on-going monitoring, labor and management, 2)Inflation adjustment, and 3) Market risk premium. The sum of the expected costs by year is discounted using the Company’s credit adjusted risk free interest rate from the time it expects to pay the retirement obligation to the time it incurs the obligation. The reclamation and environmental obligation recorded on the balance sheet is equal to the present value of the estimated costs.
	The current undiscounted estimate of the reclamation costs for existing disturbances at the Sleeper Gold Project is $3,915,626 as required by U.S Bureau of Land Management and the Nevada Department of Environmental Protection.

	The potential tax benefits of net operating and non capital losses have not been recognized in these financial statements because the Company cannot be assured it is more likely than not it will utilize the net operating or non capital losses carried forward in future years.
	Accounting for uncertainty for Income Tax
	Income taxes are determined using assets and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. In addition, a valuation allowance is established to reduce any deferred tax asset for which it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.
	Effective July 1, 2009, the Company adopted the interpretation for accounting for uncertainty in income taxes which was an interpretation of the accounting standard accounting for income taxes. This interpretation created a single model to address accounting for uncertainty in tax positions. This interpretation clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements.
	As at June 30, 2014 and 2013, the Company’s consolidated balance sheets did not reflect a liability for uncertain tax positions, nor any accrued penalties or interest associated with income tax uncertainties. The Company is subject to income taxation at the federal and state levels. The Company is subject to US federal tax examinations for the tax years 2009 through 2014. Loss carryforwards generated or utilized in years earlier than 2009 are also subject to examination and adjustment. The Company has no income tax examinations in process.

Principal_Accounting_Policies_

Principal Accounting Policies (Policies)	12 Months Ended
	Jun. 30, 2014
Principal Accounting Policies [Abstract]	'
Basis of Presentation and Preparation	'
	Basis of Presentation and Preparation
	The consolidated financial statements are prepared by management in accordance with U.S generally accepted accounting principles (“U.S. GAAP”). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
Use of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
	Significant estimates made by management in the accompanying financial statements include collectability of amounts receivable, the adequacy of the Company’s asset retirement obligations, fair value of stock based compensation and valuation of deferred tax assets.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	All highly liquid investments with maturities of three months or less at the date of purchase are classified as cash and cash equivalents.
Marketable Securities	'
	Marketable Securities
	The Company classifies its marketable securities as available-for-sale securities. The securities are measured at fair market value in the financial statements with unrealized gains and temporary losses on investments classified as available for sale are included within accumulated other comprehensive income, net of any related tax effect. Upon realization, such amounts are reclassified from accumulated other comprehensive income to other income, net, realized gains and losses and other than temporary impairments, if any, are reflected in the statements of operations as other income or expenses. The Company does not recognize changes in the fair value of its investments in income unless a decline in value is considered other than temporary.
Fair Value Measurements	'
	Fair Value Measurements
	The Company has adopted FASB ASC 820, Fair Value Measurements and Disclosures, which defines fair value, establishes guidelines for measuring fair value and expands disclosures regarding fair value measurements. The Company applies fair value accounting for all financial assets and liabilities and non – financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.
	The Company has adopted FASB ASC 825, Financial Instruments, which allows companies to choose to measure eligible financial instruments and certain other items at fair value that are not required to be measured at fair value. The Company has not elected the fair value option for any eligible financial instruments.
Stock Based Compensation	'
	Stock Based Compensation
	The Company has adopted the provisions of FASB ASC 718, “Stock Compensation” (“ASC 718”), which establishes accounting for equity instruments exchanged for employee services. Under the provisions of ASC 718, stock-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity grant). New shares of the Company’s Common Stock will be issued for any options exercised or awards granted.
Comprehensive Income	'
	Comprehensive Income
	FASB ASC 220“Reporting Comprehensive Income” establishes standards for the reporting and display of comprehensive income and its components in the financial statements.
Mineral Properties	'
	Mineral Properties
	Mineral property acquisition costs are capitalized when incurred and will be amortized using the units –of – production method over the estimated life of the reserve following the commencement of production. If a mineral property is subsequently abandoned or impaired, any capitalized costs will be expensed in the period of abandonment or impairment.
	Acquisition costs include cash consideration and the fair market value of shares issued on the acquisition of mineral properties.
Exploration Costs	'
	Exploration Costs
	Exploration costs, which include maintenance, development and exploration of mineral claims, are expensed as incurred. When it is determined that a mineral deposit can be economically developed as a result of establishing proven and probable reserves, the costs incurred after such determination will be capitalized and amortized over their useful lives. To date, the Company has not established the commercial feasibility of its exploration prospects; therefore, all exploration costs are being expensed.
Derivatives	'
	Derivatives
	The Company accounts for its derivative instruments not indexed to our stock as either assets or liabilities and carries them at fair value. Derivatives that are not defined as hedges must be adjusted to fair value through earnings.
	Warrants and options issued and outstanding in prior periods with exercise prices denominated in Canadian dollars were not considered indexed to our stock, as their exercise price was not in the Company’s functional currency of the US dollar, and therefore no longer qualified for the scope exception and were accounted for as a derivative. These warrants and options were reclassified as liabilities under the caption “Warrant liability” and recorded at estimated fair value at each reporting date, computed using the Black-Scholes valuation method. Changes in the liability from period to period were recorded in the Statements of Operations under the caption “Change in fair value of warrant liability.”
	The Company elected to record the change in fair value of the warrant liability as a component of other income and expense on the statement of operations as we believe the amounts recorded relate to financing activities and not as a result of our operations.
Property and Equipment	'
	Property and Equipment
	Equipment is recorded at cost less accumulated depreciation. All equipment is amortized over its estimated useful life at the following annual rates:
	Computer equipment	30% declining balance
	Equipment	20% declining balance
	Furniture and fixtures	20% declining balance
	Exploration equipment	20% declining balance
Income Taxes	'
	Income Taxes
	Income taxes are determined using assets and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. In addition, a valuation allowance is established to reduce any deferred tax asset for which it is determined that it is more likely than not that some portion of the deferred tax asset will not be realized.
	Potential benefits of income tax losses are not recognized in the accounts until realization is more likely than not. The Company has adopted FASB ASC 740 as of its inception. Pursuant to FASB ASC 740 the Company is required to compute tax asset benefits for net operating losses carried forward. Potential benefits of net operating losses have not been recognized in these financial statements because the Company cannot be assured it is more likely than not it will utilize the net operating losses carried forward in future periods; and accordingly is offset by a valuation allowance. FIN No.48 prescribes a recognition threshold and measurement attribute for financial statement recognition and measurement of tax positions taken in tax returns.
	To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, such amounts would be accrued and classified as a component of income tax expense in our Consolidated Statements of Operations and Comprehensive Loss. The Company elected this accounting policy, which is a continuation of our historical policy, in connection with our adoption of FIN 48.
Net Income (Loss) Per Share	'
	Net Income (Loss) Per Share
	Basic earnings(loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of shares outstanding during each period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.
	For the years ended June 30, 2014, 2013 and 2012 the shares of common stock equivalents related to outstanding stock option and stock purchase warrants have not been included in the diluted per share calculation as they are anti-dilutive as the Company has recorded a net loss from continuing operations for each year.
Revenue Recognition	'
	Revenue Recognition
	Revenue is recognized when persuasive evidence that an agreement exists, the risks and rewards of ownership pass to the purchaser, the selling price is fixed and determinable; or collection is reasonably assured. The passing of title to the purchaser is based on the terms of the purchase and sale agreement.
Concentration of Credit Risk and Amounts Receivable	'
	Concentration of Credit Risk and Amounts Receivable
	Financial instruments that potentially subject the Company to a concentration of credit risk consist principally of cash and cash equivalents and amounts receivable. The Company maintains cash in accounts which may, at times, exceed federally insured limits. At June 30, 2014, the balances of approximately $4.8 million were in excess of federally insured limits. We deposit our cash with financial institutions which we believe have sufficient credit quality to minimize the risk of loss.
	Impuesto al Valor Agregado taxes (IVA) are recoverable value-added taxes charged by the Mexican government on goods sold and services rendered at a rate of 16%. Under certain circumstances, these taxes are recoverable by filing a tax return and as determined by the Mexican taxing authority. Each period, receivables are reviewed for collectability. When a receivable is determined to not be collectable we allow for the receivable until we are either assured of collection or assured that a write-off is necessary. Allowances in association with our receivable from IVA from our Mexico subsidiaries is based on our determination that the Mexican government may not allow the complete refund of these taxes. The Company believes that all amounts recorded as a receivable from the Mexican government will be recovered.
Foreign Currency	'
	Foreign Currency
	The parent company’s functional currency is the United States dollar. The functional currencies of the Company’s wholly-owned subsidiaries are the U.S. Dollar and the Canadian Dollar. Monetary assets and liabilities denominated in foreign currencies are translated using the exchange rate prevailing at the consolidated balance sheet date. Foreign currency transaction gains and losses are included in the statement of operations and comprehensive loss. The aggregate foreign transaction loss for the year ended June 30, 2014 is $41,168.
	The financial statements of the subsidiaries are translated to United States dollars in accordance with ASC 830 using period-end rates of exchange for assets and liabilities, and average rates of exchange for the period for revenues and expenses. Translation gains (losses) are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity.

	Accounting Pronouncements Adopted During the Period
	i)	ASU 2014-10
	In June 2014, the FASB issued ASU 2014-10, “Development Stage Entities (Topic 915)”. The amendments in ASU 2014-10 remove all incremental financial reporting requirements from U.S. GAAP for development stage entities, including the removal of Topic 915, Development Stage Entities, from the FASB Accounting Standards Codification. In addition, the ASU: (a) adds an example disclosure in Topic 275, Risks and Uncertainties, to illustrate one way that an entity that has not begun planned principal operations could provide information about the risks and uncertainties related to the company’s current activities; and (b) removes an exception provided to development stage entities in Topic 810, Consolidation, for determining whether an entity is a variable interest entity. The presentation and disclosure requirements in Topic 915 will no longer be required for the first annual reporting period beginning after December 15, 2014. The withdrawal of the presentation and disclosure requirements of Topic 915 is effective for annual reporting periods beginning after December 15, 2015. The revised consolidation standards are effective for annual reporting periods beginning after December 15, 2016. Early adoption is permitted for any annual reporting period or interim period for which an entity’s financial statements have not yet been issued or made available for issuance. The Company has early adopted ASU 2014-10 and impacts of its adoption have been reflected throughout the Company’s consolidated financial statements, with the significant effect being the elimination of disclosures of certain cumulative amounts incurred during the period from inception to the period end reporting date.
	New Accounting Pronouncements Not Yet Adopted
	i)	ASU 2013-05
	In March 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-05, “Foreign Currency Matters (Topic 830); Parents Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” This guidance applies to the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business (other than a sale of substance real estate or conveyance of oil and gas, mineral rights) within a foreign entity. ASU No. 2013-05 is effective prospectively for fiscal years (and interim reporting periods with those years) beginning after December 15, 2013. We are currently reviewing the provisions of ASU No. 2013-05 on our financial position or results of operations.
	ii)	ASU 2013-11
	In July 2013, FASB issued ASU 2013-11, “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exits.” The FASB’s objective in issuing this ASU is to eliminate diversity in practice resulting from a lack of guidance on this topic in current U.S. GAAP. This ASU applies to all entities with unrecognized tax benefits that also have tax loss or tax credit carryforwards in the same tax jurisdiction as of the reporting date. ASU No. 2013-11 is effective for public entities for fiscal years beginning after December 15, 2013, and interim periods within those years. Early adoption is permitted. The amendments should be applied to all unrecognized tax benefits that exist as of the effective date. Entities may choose to apply the amendments retrospectively to each prior reporting period presented. We are currently assessing the impact of the adoption of this update on our financial position or results of operations.
