	NOTE 1 – Organization
	Liberty Star Uranium & Metals Corp. (the “Company”, “we” or “Liberty Star”) was formerly Liberty Star Gold Corp. and formerly Titanium Intelligence, Inc. (“Titanium”). Titanium was incorporated on August 20, 2001 under the laws of the State of Nevada. On February 5, 2004 we commenced operations in the acquisition and exploration of mineral properties business. Big Chunk Corp. (“Big Chunk”) is our wholly owned subsidiary and was incorporated on December 14, 2003 in the State of Alaska. Big Chunk is engaged in the acquisition and exploration of mineral properties business in the State of Alaska. Redwall Drilling Inc. (“Redwall”) was our wholly owned subsidiary and was incorporated on August 31, 2007 in the State of Arizona. Redwall performed drilling services on the Company’s mineral properties. Redwall ceased drilling activities in July 2008 and was dissolved on March 30, 2010. In April 2007, we changed our name to Liberty Star Uranium & Metals Corp. We are considered to be an exploration stage company, as we have not generated any revenues from operations.
	These consolidated financial statements include the results of operations and cash flows of Liberty Star Uranium & Metals Corp. and its wholly owned subsidiaries, Big Chunk and Redwall, from the dates of acquisition. All significant intercompany accounts and transactions were eliminated upon consolidation.
	These consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) with the on-going assumption that we will be able to realize our assets and discharge our liabilities in the normal course of business. However, certain conditions noted below currently exist which raise substantial doubt about our ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the amounts and classifications of assets and liabilities that might be necessary should we be unable to continue as a going concern. Our operations have primarily been funded by the issuance of common stock and debt. Continued operations are dependent on our ability to complete equity financings or generate profitable operations in the future. Management’s plan in this regard is to secure additional funds through future equity financings, joint venture agreements or debt. Such financings may not be available, or may not be available on reasonable terms.

Summary of significant accounting policies [Text Block]	'
	NOTE 2 – Summary of significant accounting policies
	The summary of significant accounting policies presented below is designed to assist in understanding the Company's consolidated financial statements. Such consolidated financial statements and accompanying notes are the representations of the Company’s management, who is responsible for their integrity and objectivity. These accounting policies conform to accounting principles generally accepted in the United States of America in all material respects, and have been consistently applied in preparing the accompanying consolidated financial statements. The significant accounting policies adopted by the Company are as follows:
	Use of estimates
	The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	The valuation of stock-based compensation, classification and valuation of common stock purchase warrants, classification and value of embedded conversion options, value of beneficial conversion features, valuation allowance on deferred tax assets, the determination of useful lives and recoverability of depreciable assets, accruals, and contingencies are significant estimates made by management. It is at least reasonably possible that a change in these estimates may occur in the near term.
	Principles of consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Big Chunk and Redwall, from the dates of acquisition, February 5, 2004 and August 31, 2007, respectively. All significant intercompany accounts and transactions have been eliminated upon consolidation.
	Cash and cash equivalents
	We consider cash held at banks and all highly liquid investments with original maturities of three months or less to be cash and cash equivalents. We maintain our cash in bank deposit accounts which, for periods of time, may exceed federally insured limits. At January 31, 2013 and 2012, we had cash in bank deposit accounts that exceeded federally insured limits of $0 and $0, respectively.
	Mineral claim costs
	We account for costs incurred to acquire, maintain and explore mineral properties as a charge to expense in the period incurred until the time that a proven mineral resource is established, at which point development of the mineral property would be capitalized. Currently, we do not have any proven mineral resources on any of our mineral properties.
	Property and equipment
	Property and equipment is stated at cost. We capitalize all purchased equipment over $500 with a useful life of more than one year. Depreciation is calculated using the straight line method over the estimated useful lives of the assets. Leasehold improvements are stated at cost and are amortized over their estimated useful lives or the lease term, whichever is shorter. Maintenance and repairs are expensed as incurred while betterments or renewals are capitalized. Property and equipment is reviewed periodically for impairment. The estimated useful lives range from 3 to 7 years.
	Convertible promissory notes
	We report convertible promissory notes as liabilities at their carrying value less unamortized discounts, which approximates fair value. We bifurcate conversion options and detachable common stock purchase warrants and report them as liabilities at fair value at each reporting period when required in accordance with the applicable accounting guidance. When convertible promissory notes are converted into shares of our common stock in accordance with the debt’s terms, no gain or loss is recognized. We account for inducements to convert as an expense in the period incurred, included in debt conversion expense.
	Common stock purchase warrants
	We report common stock purchase warrants as equity unless a condition exists which requires reporting as a derivative liability at fair market value. For common stock purchase warrants reported as a derivative liability, as well as new and modified warrants reported as equity, we utilize the Black-Scholes valuation method in order to estimate fair value.
	Environmental expenditures
	Our operations have been and may in the future be affected from time to time in varying degree by changes in environmental regulations, including those for future removal and site restoration costs. The likelihood of new regulations and their overall effect upon us are not predictable. We provide for any reclamation costs in accordance with the accounting standards codification section 410-30. It is management’s opinion that we are not currently exposed to significant environmental and reclamation liabilities and have recorded no reserve for environmental and reclamation expenditures at January 31, 2013 and 2012.
	Fair Value of Financial Assets and Liabilities
	The Company measures and discloses certain financial assets and liabilities at fair value. Authoritative guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Authoritative guidance also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:
	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	Income taxes
	Income taxes are recorded using the asset and liability method. Under the asset and liability method, tax assets and liabilities are recognized for the tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future tax assets and liabilities are measured using the enacted tax rates expected to apply when the asset is realized or the liability settled. The effect on future tax assets and liabilities of a change in tax rates is recognized in income in the period that enactment occurs. To the extent that the Company does not consider it more likely than not that a future tax asset will be recovered, it provides a valuation allowance against the excess. Interest and penalties associated with unrecognized tax benefits, if any, are classified as additional income taxes in the statement of operations. With few exceptions, we are no longer subject to U.S. federal, state and local examinations by tax authorities for years before 2009.
	Net loss per share
	Basic net loss per share is computed by dividing net loss attributable to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share takes into consideration shares of common stock outstanding (computed under basic loss per share) and potentially dilutive shares of common stock that are not anti-dilutive.
	Net loss per share – continued
	At January 31, 2013 and 2012, there were 174,773,105 and 187,086,566 potentially dilutive instruments outstanding, respectively. These instruments were not included in the determination of diluted loss per share as their effect was anti-dilutive.
	Statement Presentation
	Certain amounts in the prior-year financial statements have been reclassified for comparative purposes to conform with the presentation in the current-year financial statements.
	Recently issued accounting standards
	There are no recent pronouncements that are expected to have a material impact on our financial position and results of operations.

	The Company is in the exploration stage, has incurred losses from operations, and requires additional funds for further exploratory activity and to maintain its claims prior to attaining a revenue generating status. There are no assurances that a commercially viable mineral deposit exists on any of our properties. In addition, the Company may not find sufficient ore reserves to be commercially mined. As such, there is substantial doubt about the Company’s ability to continue as a going concern.

	NOTE 4– Mineral claims
	At January 31, 2013 we held a 100% interest in 417 standard Federal lode mining claims on the Colorado Plateau Province of Northern Arizona (the “North Pipes Claims”).
	At January 31, 2013 we held a 100% interest in 99 standard Federal lode mining claims located in the Tombstone region of Arizona. The mineral claims are owned by JABA US Inc, an Arizona Corporation in which two of our directors are owners. At January 31, 2013 we held Arizona State Land Department Mineral Exploration Permits covering 4,126.9 acres in the Tombstone region of Arizona.
	At January 31, 2013 we held an option to explore 26 standard Federal Lode mining claims located in the East Silver Bell region of northwest Tucson, Arizona. The mineral claims are owned by JABA US Inc., an Arizona Corporation in which two of our directors are owners.
	At January 31, 2013 we held a 100% interest in 612 Alaska State mining claims in the Iliamna region of Southwestern Alaska, located on the north side of the Cook Inlet, approximately 200 miles southwest of the city of Anchorage, Alaska (the “Big Chunk Claims”). We have designated 199 of these claims for transfer to Northern Dynasty in conjunction with a pending loan settlement agreement.
	We relinquished our Bonanza Hills claims in Alaska during 2012, to the State of Alaska.
	Title to mineral claims involves certain inherent risks due to difficulties of determining the validity of certain claims as well as potential for problems arising from the frequently ambiguous conveyance history characteristic of many mineral properties. The Company has investigated titles to all its mineral properties and, to the best of its knowledge, except as noted above for the Bonanza Hills Claims, titles to all properties are in good standing as of January 31, 2013.

	NOTE 7 – Convertible promissory notes
	We issue convertible promissory notes in private placements of our securities to institutional investors pursuant to exemptions from registration set out in Rule 506 of Regulation D under the Securities Act of 1933.
	On July 15, 2010 we issued a secured convertible promissory note bearing interest at a rate of 10% per annum compounded monthly (the “Convertible Note”) to Northern Dynasty Minerals Ltd (“Northern Dynasty”). During the year ended January 31, 2012 the agreement with Northern Dynasty was amended to issue additional secured convertible promissory notes totaling $730,174 to reimburse Northern Dynasty for assessment work, rental fees, cash in lieu of assessment work and filing fees on the mineral claims that was paid in fiscal 2011 and fiscal 2012 because we could not come to an agreement on the earn-in option and joint venture agreement with Northern Dynasty. Principal balance of the Convertible Notes at January 31, 2013 and 2012 was $3,730,174. Accrued interest on the Convertible Notes at January 31, 2013 and 2012 was $972,617 and $526,971, respectively.
	As part of the transaction noted above, Northern Dynasty could earn a 60% interest in our Big Chunk project in Alaska (the “Joint Venture Claims”) by spending $10,000,000 on those properties over six years. The borrowings from Northern Dynasty could be applied as part of Northern Dynasty’s earn-in requirements. Northern Dynasty’s minimum annual expenditures under the earn-in would be the minimum level necessary to keep the Joint Venture Claims in good standing. Northern Dynasty could elect to abandon the earn-in at any time on 30 days’ notice, so long as sufficient annual labor was performed, or a cash payment in lieu of labor was made, in order to fulfill the annual labor requirements for the Joint Venture Claims for a minimum of 12 months after termination of the earn-in. As of January 31, 2013, no such notice by Northern Dynasty has been received.
	On November 14, 2012, we signed a loan settlement agreement with Northern Dynasty which would have discharged the $3,730,174 principal balance and $972,617 of accrued interest for the 2010 Convertible Note and would have terminated Northern Dynasty’s earn-in rights. In exchange for the settlement, we initiated the transfer of 199 Alaska mining claims to Northern Dynasty’s subsidiary, U5 Resources. However, since a third party filed liens against the claims before the transfer could be completed, we have not recorded the settlement transaction as of January 31, 2013, pending resolution of the lien claims.

The shares that we sell to Fairhills Capital must be registered stock, among other conditions of investment.
	In August and September, 2013, we issued 2,934,763 shares to two individuals in exchange for services valued at $61,938.					In connection with the Investment Agreement, we also entered into a registration rights agreement with Fairhills. Pursuant to this registration rights agreement, we registered with the Securities and Exchange Commission 185,000,000 shares of the common stock underlying the Investment Agreement.
	In September, 2013, we sold 2,157,497 units to one investor for gross proceeds of $50,000. Each unit consisted of one common share of our company and one non-transferable share purchase warrant. Each share purchase warrant entitles the investor to purchase one additional common share of our company at a price of $0.0324 until September 5, 2016.					On November 13, 2012, we filed a 424B prospectus with the Securities Exchange Commission, acknowledging the assignment of all the rights under our investment agreement with Fairhills Capital Offshore Ltd. (Fairhills) to Deer Valley Management, LLC (Deer Valley). The Investment Agreement and other associated agreements were assigned by Fairhills to Deer Valley on November 6, 2012, and Liberty Star consented to the assignment. Fairhills and Deer Valley share the same ownership and management and there has not been any substantial change to our arrangement under the Investment Agreement as a result of the Assignment.
	On October 30, 2013, the Company entered into an investment agreement in which with KVM Capital Partners LLC, a New York limited liability company (“KVM”). Pursuant to the agreement, KVM has agreed to purchase up to $8,000,000 of our common stock over a period of up to thirty-six (36) months. The purchase price per share to be paid by KVM shall be calculated at a twenty percent ( 20%) discount to the lowest volume weighted average price of the common stock as reported by Bloomberg, L.P. during the five (5) consecutive trading days immediately prior to the receipt by KVM of the put notice. We initially reserved 244,500,000 shares of our common stock for issuance under the KVM Investment Agreement. In connection with the KVM Investment Agreement, we also entered into a registration rights agreement with KVM, pursuant to which we are obligated to file a registration statement with the SEC covering 244,500,000 shares of our common stock underlying the KVM Investment Agreement within 21 days after the closing of the transaction. In addition, we are obligated to use all commercially reasonable efforts to have the registration statement declared effective by the SEC and maintain the effectiveness of such registration statement until termination of the KVM Investment Agreement. On November 6, 2013, we filed form S-1 related to the KVM investment agreement. As of October 31, 2013, no shares were purchased by the investor.					At January 31, 2013 and subsequently, we have issued 59,670,369 and 29,479,597shares, respectively, of common stock for gross proceeds of $1,175,000 and $250,000, respectively, related to this financing agreement. As a result, in the future we would potentially be eligible to receive up to $8,575,000 on the issuance of an additional 95,850,034 shares. We are currently authorized to issue 1,250,000,000 shares of our common stock. Deer Valley has agreed to refrain from holding an amount of shares which would result in Deer Valley owning more than 4.99% of the then-outstanding shares of our common stock at any one time, or 62,375,000 shares. At an assumed purchase price under the Investment of $0.008 (equal to 72.5% of the closing price of our common stock of $0.011 on May 13, 2013), we will be able to receive up to $766,800 in gross proceeds.
	During the nine months ended October 31, 2013 there were 7,423,624 stock options granted at an exercise price of $0.03 per share, exercisable until September 5, 2023 with a fair value at grant date of $215,912. The options granted will be 100% vested for directors and shall vest in 25% increments on a yearly basis over the next four years for employees. In order to calculate the fair value of stock options at the date of grant, we use the Black-Scholes option pricing model. The volatility used was based on our historical volatility. The expected term was determined based on the simplified method outlined in Staff Accounting Bulletin No. 110. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Remaining stock option expense to be recognized in future periods related to the award is $48,840.					As of January 31, 2013, there were 94,059,629 whole share purchase warrants outstanding and exercisable.

	We estimate the fair value of option awards on the grant date using the Black-Scholes valuation model. The Company uses historical volatility, disregarding identifiable periods of time in which share price was extraordinarily volatile due to certain events that are not expected to recur during the expected term, as its method to estimate expected volatility. The Company used the following assumptions to estimate the fair value of stock option grants to employees and non-employees:
			Expected			Expected dividend				Risk-free interest
	Grant date		volatility			yield		Expected term		rate	Forfeiture rate
	10-Jan-12		128%			0%		10 years		2%	10%
	13-Dec-12		174%			0%		3 years		0.34%	0%
	1-Jan-13		173%			0%		3 years		0.36%	0%
	1-Jan-13		171%			0%		3 years		0.41%	0%
	The weighted average grant date fair value of the options granted during the year ended January 31, 2012 was $0.022 per option. There were 7,359,399 shares of warrants granted to vendors for service provided and the company recorded the expense into stock compensation expense. There were no options exercised during the year ended January 31, 2013. During the year ended January 31, 2013, a total of 2,625,000 options, of which 2,562,500 were vested, were forfeited by two former employees who declined to exercise the options within 90 days of termination of employment.
	Share-based compensation expense is reported in our statement of operations as follows:
		31-Jan-13			31-Jan-12
Geological and geophysical costs	$	624		$	1,237
Salaries and benefits		50,592			101,475
Investor relations		624			1,238
General and administrative		84,156			-
	$	135,996		$	103,950
At January 31, 2013 there is $51,341 unrecognized share-based compensation for all share-based awards outstanding with a weighted average remaining period for amortization of 0.94 years.

	Management has elected to provide a deferred tax asset valuation allowance equal to the potential benefit due to our history of losses. If we demonstrate the ability to generate taxable income, management will re-evaluate the allowance. The change in the valuation allowance of $832,000 and 176,000 in the years ended January 31, 2013 and 2012 primarily represents the benefit of the change in net operating loss carry-forwards during the period. As of January 31, 2013, our estimated net operating loss carryforward is approximately $27,980,000 and will expire beginning in 2024 through 2033.
	Internal Revenue Code Section 382 limits the ability to utilize net operating losses if a 50% change in ownership occurs over a three year period. Such limitation of the net operating losses may have occurred but we have not analyzed it at this time as the deferred tax asset is fully reserved. We have federal and state net operating loss carry-forwards that are available to offset future taxable income.

NOTE 13 – Fair value of financial instruments

Our financial instruments consist of cash and cash equivalents, accounts payable, accrued liabilities, convertible notes payable, notes payable, and warrant liability. It is management's opinion that we are not exposed to significant interest, currency or credit risks arising from these financial instruments. With the exception of the warrant liability, the fair value of these financial instruments approximates their carrying values based on their short maturities or for long-term debt based on borrowing rates currently available to us for loans with similar terms and maturities, which represent Level 3 input. Gains and losses recognized on changes in estimated fair value of the warrant liability are reported in other income (expense) as gain (loss) on change in fair value.

Our financial instruments consist of cash and cash equivalents, accounts payable, accrued liabilities, convertible notes payable, notes payable, and warrant liability. It is management's opinion that we are not exposed to significant interest, currency or credit risks arising from these financial instruments. With the exception of the warrant liability, the fair value of these financial instruments approximates their carrying values based on their short maturities or for long-term debt based on borrowing rates currently available to us for loans with similar terms and maturities. Gains and losses recognized on changes in estimated fair value of the warrant liability are reported in other income (expense) as gain (loss) on change in fair value.

We estimate the fair value of the warrant liability using level 3 inputs and the Black-Scholes valuation model. We use historical volatility as a method to estimate expected volatility. At October 31, 2013 and January 31, 2013 we had 2,500,000 whole share purchase warrants outstanding that contain a full ratchet down anti-dilution provision which is triggered if we enter into any lower priced issuance than $0.0264 per common share. We used the following assumptions to estimate the fair value of the warrant liability at October 31, 2013 and January 31, 2013:

We estimate the fair value of the warrant liability using level 3 inputs and the Black-Scholes valuation model. We use historical volatility as a method to estimate expected volatility. At January 31, 2012 we had 622,138 whole share purchase warrants outstanding that contain a full ratchet down anti-dilution provision which is triggered if we enter into any issuance priced lower than $0.02 per common share. At January 31, 2013 and 2012 we had 2,500,000 whole share purchase warrants outstanding that contain a full ratchet down anti-dilution provision which is triggered if we enter into any lower priced issuance than $0.0264 per common share. As a result of these provisions, these warrants are not considered indexed to our common stock and are classified as liabilities under ASC 815. We used the following assumptions to estimate the fair value of the warranty liability at January 31, 2013 and 2012:

Debt [Text Block]	' NOTE 6 – Debt
	In August, 2013, we entered into a promissory note (the “August 2013 Note”) for a principal sum of $555,000 plus accrued and unpaid interest and any other fees. The consideration is up to $500,000, which would produce an original issue discount of $55,000 if all the consideration is received. The lender paid $150,000 upon closing pursuant to the terms of the August 2013 Note. The August 2013 Note has a maturity of one year from the delivery of each payment. The August 2013 Note may be convertible into shares of common stock of our company at any time from 180 days after the date of each payment of consideration, at a conversion price which is 70% of the average of the three lowest closing prices in the 20 trading days previous to the conversion. We may repay the August 2013 Note at any time on or before 90 days from the effective date of the August 2013 Note with an interest rate of 0%, after which we may not make any further payments on the August 2013 Note prior to the maturity date without written approval from the lender. If we elect not to repay the August 2013 Note on or before 90 days from the effective date of the August 2013 Note, a one-time interest charge of 12% will be applied to the principal sum.

	NOTE 8 – Subsequent events	In February, March, April and May, 2013, we issued 29,479,597 shares for gross proceeds of $250,000 related to the investment agreement with Deer Valley Management, LLC.
	On November 18, 2013, we entered into a securities purchase agreement, whereby we agreed to issue a convertible note to one lender in the principal amount of $250,000. The Note is payable in full on November 18, 2014 and bears no interest except in an event of default. The lender may, at its option, after the 183 rd day following the closing date, convert the principal amount or any portion of such principal amount of the Note into shares of common stock of our company at the price equal to the lesser of (a) 100% of the volume weighted average price (VWAP), as reported on the closing date (November 18, 2013), and (b) 70% of the average of the 5 day VWAP immediately prior to the day of conversion.	In February, 2013, we sold 3,448,276 units to one investor for gross proceeds of $40,000. Each unit consisted of one common share and one common share of our company and one non transferable share purchase warrant. Each share purchase warrant entitles the investor to purchase one additional common share of our company at a price of $0.0162 until February 7, 2016.
	On December 9, 2013, we received additional consideration of $75,000 pursuant to the terms of the August 2013 Note.	In February, 2013, we issued 1,526,718 units to one investor in exchange for services performed for the company with a value of $20,000.

Recovered_Sheet1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 31, 2013
Use of estimates [Policy Text Block]	'
	Use of estimates
	The preparation of financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	The valuation of stock-based compensation, classification and valuation of common stock purchase warrants, classification and value of embedded conversion options, value of beneficial conversion features, valuation allowance on deferred tax assets, the determination of useful lives and recoverability of depreciable assets, accruals, and contingencies are significant estimates made by management. It is at least reasonably possible that a change in these estimates may occur in the near term.
Principles of consolidation [Policy Text Block]	'
	Principles of consolidation
	The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Big Chunk and Redwall, from the dates of acquisition, February 5, 2004 and August 31, 2007, respectively. All significant intercompany accounts and transactions have been eliminated upon consolidation.
Cash and cash equivalents [Policy Text Block]	'
	Cash and cash equivalents
	We consider cash held at banks and all highly liquid investments with original maturities of three months or less to be cash and cash equivalents. We maintain our cash in bank deposit accounts which, for periods of time, may exceed federally insured limits. At January 31, 2013 and 2012, we had cash in bank deposit accounts that exceeded federally insured limits of $0 and $0, respectively.
Mineral claim costs [Policy Text Block]	'
	Mineral claim costs
	We account for costs incurred to acquire, maintain and explore mineral properties as a charge to expense in the period incurred until the time that a proven mineral resource is established, at which point development of the mineral property would be capitalized. Currently, we do not have any proven mineral resources on any of our mineral properties.
Property and equipment [Policy Text Block]	'
	Property and equipment
	Property and equipment is stated at cost. We capitalize all purchased equipment over $500 with a useful life of more than one year. Depreciation is calculated using the straight line method over the estimated useful lives of the assets. Leasehold improvements are stated at cost and are amortized over their estimated useful lives or the lease term, whichever is shorter. Maintenance and repairs are expensed as incurred while betterments or renewals are capitalized. Property and equipment is reviewed periodically for impairment. The estimated useful lives range from 3 to 7 years.
Convertible promissory notes [Policy Text Block]	'
	Convertible promissory notes
	We report convertible promissory notes as liabilities at their carrying value less unamortized discounts, which approximates fair value. We bifurcate conversion options and detachable common stock purchase warrants and report them as liabilities at fair value at each reporting period when required in accordance with the applicable accounting guidance. When convertible promissory notes are converted into shares of our common stock in accordance with the debt’s terms, no gain or loss is recognized. We account for inducements to convert as an expense in the period incurred, included in debt conversion expense.
Common stock purchase warrants [Policy Text Block]	'
	Common stock purchase warrants
	We report common stock purchase warrants as equity unless a condition exists which requires reporting as a derivative liability at fair market value. For common stock purchase warrants reported as a derivative liability, as well as new and modified warrants reported as equity, we utilize the Black-Scholes valuation method in order to estimate fair value.
Environmental expenditures [Policy Text Block]	'
	Environmental expenditures
	Our operations have been and may in the future be affected from time to time in varying degree by changes in environmental regulations, including those for future removal and site restoration costs. The likelihood of new regulations and their overall effect upon us are not predictable. We provide for any reclamation costs in accordance with the accounting standards codification section 410-30. It is management’s opinion that we are not currently exposed to significant environmental and reclamation liabilities and have recorded no reserve for environmental and reclamation expenditures at January 31, 2013 and 2012.
Fair Value of Financial Assets and Liabilities [Policy Text Block]	'
	Fair Value of Financial Assets and Liabilities
	The Company measures and discloses certain financial assets and liabilities at fair value. Authoritative guidance defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Authoritative guidance also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:
	Level 1 - Quoted prices in active markets for identical assets or liabilities.
	Level 2 - Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
Income taxes [Policy Text Block]	'
	Income taxes
	Income taxes are recorded using the asset and liability method. Under the asset and liability method, tax assets and liabilities are recognized for the tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Future tax assets and liabilities are measured using the enacted tax rates expected to apply when the asset is realized or the liability settled. The effect on future tax assets and liabilities of a change in tax rates is recognized in income in the period that enactment occurs. To the extent that the Company does not consider it more likely than not that a future tax asset will be recovered, it provides a valuation allowance against the excess. Interest and penalties associated with unrecognized tax benefits, if any, are classified as additional income taxes in the statement of operations. With few exceptions, we are no longer subject to U.S. federal, state and local examinations by tax authorities for years before 2009.
Net loss per share [Policy Text Block]	'
	Net loss per share
	Basic net loss per share is computed by dividing net loss attributable to common shareholders by the weighted average number of shares of common stock outstanding during the period. Diluted net loss per share takes into consideration shares of common stock outstanding (computed under basic loss per share) and potentially dilutive shares of common stock that are not anti-dilutive.
Statement Presentation [Policy Text Block]	'
	Statement Presentation
	Certain amounts in the prior-year financial statements have been reclassified for comparative purposes to conform with the presentation in the current-year financial statements.
Recently issued accounting standards [Policy Text Block]	'
	Recently issued accounting standards
	There are no recent pronouncements that are expected to have a material impact on our financial position and results of operations.
