Organization

Organization	12 Months Ended
	Jan. 31, 2015
Organization [Text Block]	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. We formed the wholly owned subsidiary, Hay Mountain Super Project LLC (“HMSP”) incorporated on October 24, 2014, to serve as the primary holding company for development of the potential ore bodies encompassed in the Hay Mountain area of interest in Arizona. In April 2007, we changed our name to Liberty Star Uranium & Metals Corp. 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 HMSP. 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_account

Summary of significant accounting policies	12 Months Ended
	Jan. 31, 2015
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 HMSP. 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, 2015 and 2014, 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.
	Long-lived assets and impairment of long-lived assets 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.
	We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Recoverability of a long-lived asset group to be held and used in operations is measured by a comparison of the carrying amount to the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset group. If such asset group is considered to be impaired, the impairment loss is measured as the amount by which the carrying amount of the asset group exceeds its fair value. Long-lived assets to be disposed of are carried at the lower of cost or fair value less the costs of disposal.
	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.
	Derivative liabilities   The valuation of the derivative liability of our warrants is determined through the use of a Monte Carlo options model that values the liability of the warrants based on a risk-neutral valuation where the price of the option is its discounted expected value. The technique applied generates a large number of possible (but random) price paths for the underlying common stock via simulation, and then calculates the associated exercise value (i.e. “payoff”) of the option for each path. These payoffs are then averaged and discounted to a current valuation date resulting in the fair value of the option.
	The valuation of the derivative liability attached to the convertible debt is arrived at through the use of a Monte Carlo model that values the derivative liability within the notes. The technique applied generates a large number of possible (but random) price paths for the underlying (or underlyings) via simulation, and then calculates the associated payment value (cash, stock, or warrants) of the derivative features. The price of the underlying common stock is modeled such that it follows a geometric Brownian motion with constant drift, and elastic volatility (increasing as stock price decreases). The stock price is determined by a random sampling from a normal distribution. Since the underlying random process is the same, for enough price paths, the value of the derivative is derived from path dependent scenarios and outcomes. The features in the notes are analyzed and incorporated into the model included the conversion features with the reset provisions, the call/redemption/prepayment options, and the default provisions. Based on these features, there are six primary events that can occur; payments are made in cash; payments are made with stock; the note holder converts upon receiving a redemption notice; the note holder converts the note; the issuer redeems the note; or the Company defaults on the note. The model simulates the underlying economic factors that influenced which of these events would occur, when they were likely to occur, and the specific terms that would be in effect at the time (i.e. stock price, conversion price, etc.). Probabilities are assigned to each variable such as redemption likelihood, default likelihood, and timing and pricing of reset events over the remaining term of the notes based on management projections. This leads to a cash flow simulation over the life of the note. A discounted cash flow for each simulation is completed, and is compared to the discounted cash flow of the note without the embedded features, thus determining a value for the derivative liability.
	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.
	Stock based compensation   The Company recognizes stock-based compensation for all share-based payment awards made to employees based on the estimated fair values, using the Black-Scholes option pricing model.
	Non-employee stock-based compensation is accounted for based on the fair value of the related stock or options or the fair value of the services on the grant date, whichever is more readily determinable. The fair value of options to be granted are estimated on the date of each grant using the Black-Scholes option pricing model and amortized ratably over the option's vesting periods, which approximates the service period.
	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 as of January 31, 2015 and 2014.
	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 2010.
	Net income (loss) per share
	Basic net income (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 income (loss) per share takes into consideration shares of common stock outstanding (computed under basic income or loss per share) and potentially dilutive shares of common stock that are not anti-dilutive. For the year ended January 31, 2015, potentially dilutive shares included in the calculation of diluted net income per share included 1,345,666 shares related to warrants and 119,442,929 shares related to convertible promissory notes.  For the year ended January 31, 2014, potentially dilutive 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
	During the fiscal year 2015, the Company elected to early adopt Accounting Standards Update No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements. The adoption of this ASU allows the Company to remove the inception to date information and all references to exploration stage.

Going_concern

Going concern	12 Months Ended
	Jan. 31, 2015
Going concern [Text Block]	NOTE 3 – Going concern
	The Company 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.
	Management is working to secure additional funds through the exercise of stock warrants already outstanding, equity financings, debt financings or joint venture agreements. The consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Mineral_claims

Mineral claims [Text Block]	NOTE 4– Mineral claims
	At January 31, 2015 we held a 100% interest in 211 standard federal lode mining claims on the Colorado Plateau Province of Northern Arizona (the “North Pipes Claims”).
	At January 31, 2015 we held a 100% interest in 95 standard federal lode mining claims located in the Tombstone region of Arizona. 29 federal lode mining claims are owned by JABA US Inc, an Arizona Corporation in which two of our directors are owners and 66 federal lode mining claims belong to Liberty Star Uranium & Metals Corp. At January 31, 2015 we held Arizona State Land Department Mineral Exploration Permits covering 2,367 acres in the Tombstone region of Arizona.
	At January 31, 2015 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, 2015 we held a 100% interest in 9 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”). The transaction for 199 claims transferred to Northern Dynasty in conjunction with our loan settlement agreement has now closed, and is no longer pending.
	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.
	All of the Company’s claims for mineral properties are in good standing as of January 31, 2015.

	We issued 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 “2010 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.
	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. No such notice by Northern Dynasty was 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 $1,592,769 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, MBGS, LLC filed liens against the claims before the transfer could be completed. In March 2014 Liberty Star and Big Chunk entered into a settlement agreement with MBGS, LLC, following a resolution conference conducted in Anchorage, Alaska whereby all Northern Dynasty claims recorded by MBGS, LLC were released. As a result of the settlement agreement with MBGS, LLC, the Company completed its loan settlement agreement with Northern Dynasty and discharged the principal balance and accrued interest for the 2010 Convertible Note and terminated Northern Dynasty’s earn-in-rights. A gain of $5,322,943 for the settlement of the Northern Dynasty debt and accrued interest was recorded in other income in April 2014. As of January 31, 2015, we had no principal or interest outstanding for the 2010 Convertible Note.
	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. We elected not to pay the $150,000 portion of the August 2013 Note within 90 days from the effective date. After the $150,000 portion of the August 2013 Note became convertible, the note holder elected to convert the principal and interest totaling $186,480 into 17,937,915 shares of the company’s common stock during the months of February through May
	of 2014. On December 9, 2013, we received additional consideration of $75,000 pursuant to the terms of the August 2013 Note. We elected not to pay the $75,000 portion of the August 2013 Note within 90 days from the effective date. In June, July and August 2014, the note holder converted principal and interest totaling $93,240 into 9,983,507 shares of the Company’s common stock. On June 24, 2014 and September 3, 2014, we received additional consideration of $75,000 and $75,000, respectively, pursuant to the terms of the August 2013 Note.

As of January 31, 2015, we had $144,519 outstanding for the August 2013 Note.
	On November 18, 2013, we entered into a securities purchase agreement (the “November 2013 Note”), whereby we agreed to issue a convertible note to one lender in the principal amount of $250,000. The proceeds from the note were $225,000, which created an original issue discount of $25,000. The note was 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 183rd day (after May 20, 2014) 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. On November 13, 2014, we entered into an Assignment of Promissory Note & Acknowledgment, whereby we consented to an assignment of the note to another lender, pursuant to which $250,000 remains owing by the Company. The maturity date of the November 2013 Note was extended to November 18, 2015. From November 2014 through January 2015, the new noteholder converted principal of $102,500 into 11,792,944 shares of the Company’s common stock.

Derivative Liabilities [Text Block]	NOTE 8 – Derivative Liabilities
	The embedded conversion feature in the convertible debt instruments that the Company issued in August 2013 and November 2013 (See Note 7), that became convertible during the year ended January 31, 2015, qualified it as a derivative instrument since the number of shares issuable under the note is indeterminate based on guidance in FASB ASC 815, Derivatives and Hedging. This convertible note tainted all other equity linked instruments including outstanding warrants and fixed rate convertible debt on the date that the instrument became convertible.
	The valuation of the derivative liability of the warrants was determined through the use of a Monte Carlo options model that values the liability of the warrants based on a risk-neutral valuation where the price of the option is its discounted expected value. The technique applied generates a large number of possible (but random) price paths for the underlying common stock via simulation, and then calculates the associated exercise value (i.e. “payoff”) of the option for each path. These payoffs are then averaged and discounted to a current valuation date resulting in the fair value of the option.
	The valuation of the derivative liability attached to the convertible debt was arrived at through the use of a Monte Carlo model that values the derivative liability within the notes. The technique applied generates a large number of possible (but random) price paths for the underlying (or underlyings) via simulation, and then calculates the associated payment value (cash, stock, or warrants) of the derivative features. The price of the underlying common stock is modeled such that it follows a geometric Brownian motion with constant drift, and elastic volatility (increasing as stock price decreases). The stock price is determined by a random sampling from a normal distribution. Since the underlying random process is the same, for enough price paths, the value of the derivative is derived from path dependent scenarios and outcomes. The features in the notes that were analyzed and incorporated into the model included the conversion features with the reset provisions, the call/redemption/prepayment options, and the default provisions. Based on these features, there are six primary events that can occur; payments are made in cash; payments are made with stock; the note holder converts upon receiving a redemption notice; the note holder converts the note; the issuer redeems the note; or the Company defaults on the note. The model simulates the underlying economic factors that influenced which of these events would occur, when they were likely to occur, and the specific terms that would be in effect at the time (i.e. stock price, conversion price, etc.). Probabilities were assigned to each variable such as redemption likelihood, default likelihood, and timing and pricing of reset events over the remaining term of the notes based on management projections. This led to a cash flow simulation over the life of the note. A discounted cash flow for each simulation was completed, and it was compared to the discounted cash flow of the note without the embedded features, thus determining a value for the derivative liability.
	Key inputs and assumptions used to value the convertible notes and warrants upon issuance or tainting and also as of January 31, 2015:
	The stock projections are based on the historical volatilities for each date. These ranged in the 112-124% range. The stock price projection was modeled such that it follows a geometric Brownian motion with constant drift and a constant volatility, starting with the market stock price at each valuation date;
	An event of default would not occur during the remaining term of the note;
	Conversion of the notes to stock would be completed monthly after any holding period and would be limited based on: 25% of the last 6 months average trading volume and the ownership limit identified in the contract assuming the underlying number of common shares increases at 1% per month. The effective discount was determined based on the historical trading history of the Company based on the specific pricing mechanism in each note;
	The Company would not have funds available to redeem the notes during the remaining term of the convertible notes;
	Discount rates were based on risk free rates in effect based on the remaining term and date of each valuation and instrument.
	The holder would exercise the warrant at maturity if the stock price was above the exercise price;
	The Holder would exercise the warrant after any holding period prior to maturity at target prices starting at 2 times the exercise price for the Warrants or higher subject to monthly limits of: 25% of the last 6 months average trading volume increasing by 1% per month and the ownership limit identified in the contract assuming the underlying number of common shares increases at 1% per month.
	For the warrants with reset features, the Company assumed it would issue equity linked instruments in the quarters ended 1/31/15 through 7/31/15 at 70% of market.
	Using the results from the model, the Company recorded a derivative liability of $520,552 for the fair value of the tainted warrants previously classified in equity, a derivative liability of $6,440 for newly granted warrants (see note 11) and a derivative liability of $382,175 for the fair value of the convertible feature included in the Company’s convertible debt instruments. The derivative liability recorded for the convertible feature created a debt discount of $382,173 which is being amortized over the remaining term of the note using the effective interest rate method, and is classified as convertible debt on the balance sheet. Interest expense related to the amortization of this debt discount for the year ended January 31, 2015, was $172,968. Additionally, $182,348 of debt discount was charged to interest expense as a result of the conversion of a portion of the underlying debt instrument (See Note 7). The remaining unamortized debt discount related to the derivative liability was $26,859 as of January 31, 2015. The Company recorded the change in the fair value of the derivative liability as a gain of $482,697 to reflect the value of the derivative liability for warrants and convertible notes as $216,705 as of January 31, 2015. The Company also recorded a reclassification from derivative liability to equity of $256,748 for the conversions of a portion of the Company’s convertible notes.
	At January 31, 2014, we estimated the fair value of the derivative liability related to the warrants using level 3 inputs and the Black-Scholes valuation model. We used historical volatility as a method to estimate expected volatility. At January 31, 2014 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 were not considered indexed to our common stock and were
	classified as liabilities under ASC 815. We used the following assumptions to estimate the fair value of the derivative liability related to the warrants at January 31, 2014:
		Expected	Expected dividend	Expected	Risk-free interest
	Description	volatility	yield	term	rate
	Derivative liability at January 31, 2014	209.37%	0%	2.5	0.69%
	The following table sets forth a reconciliation of changes in the fair value of the Company’s derivative liability:
				Year Ended January 31,
				2015			2014
	Beginning balance		$	46,985		$	15,112

	The 2010 Stock Option Plan was approved and adopted by the Board of Directors on August 10, 2010. The plan allows for up to 95,500,000 shares to be granted to key employees and non-employee consultants after specific objectives are met. The 2007 Stock Option Plan was approved and adopted by the Board of Directors on December 10, 2007. The plan allows for up to 2,500,000 shares to be granted to key employees and non-employee consultants after specific objectives are met. The 2004 Stock Option Plan was approved and adopted by the Board of Directors on December 27, 2004. The plan allows for up to 962,500 shares to be granted to key employees and non-employee consultants after specific objectives are met. Employees can receive incentive stock options and non-qualified stock options while non-employee consultants can receive only non-qualified stock options. The options granted vest under various provisions using graded vesting, not to exceed four years. The options granted have a term not to exceed ten years from the date of grant or five years for options granted to more than 10% stockholders. The option price set by the Plan Administration shall not be less than the fair market value per share of the common stock on the grant date or 110% of the fair market value per share of the common stock on the grant date for options granted to greater than 10% stockholders. Options remaining available for grant under the 2010 Stock Option Plan at January 31, 2015 and 2014 are 12,500,000 and 12,500,000. Options remaining available for grant under the 2007 Stock Option Plan at January 31, 2015 and 2014 are 50,000 and 50,000, respectively. Options remaining available for grant under the 2004 Stock Option Plan at January 31, 2015and 2014 are 127,626 and 32,876, respectively.
	In September 2013, there were 7,423,624 stock options granted at an exercise price of $0.0257 per share, exercisable until September 5, 2023 with a fair value net of forfeitures, at grant date of $210,300. The options granted were 100% vested for directors and shall vest in 25% immediately and 25% over four years 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 $29,455.
	The following tables summarize the Company’s stock option activity during the years ended January 31, 2015 and 2014. Incentive stock options to employees and directors outstanding at January 31, 2015 are as follows:
							Weighted

	The options cancelled during the year ended January 31, 2015 were a result of the options expiring.  The options cancelled during the year ended January 31, 2014 were a result of employee terminations.  The aggregate intrinsic value is calculated based on the stock price of $0.0086 and $0.0195 per share as of January 31, 2015 and 2014, respectively.
	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

			$	-		$	-
	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 future taxable income, management will re-evaluate the allowance. The decrease in the valuation allowance of $1,390,000 during the year ended January 31, 2015 primarily represents the utilization of net operating loss carry-forwards during the period to offset taxable income for the year. The change in the valuation allowance of $730,000 in the year ended January 31, 2014 primarily represents the benefit of the change in net operating loss carry-forwards during the period. As of January 31, 2015, our estimated net operating loss carry-forward is approximately $26,000,000 and will expire beginning in 2025 through 2034.
	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.

	A civil action was pending in the Alaska Superior Court in Anchorage, Alaska, that concerned title to some Alaska state mining claims owned by Big Chunk Corp., a subsidiary of Liberty Star. In that action Big Chunk and Liberty Star requested a judicial determination that certain lien claim notices recorded by a party named MBGS, LLC, against the mining claims were void; and MBGS sought an order enforcing the lien claims. Liberty Star and Big Chunk filed a motion for summary judgment to invalidate the lien claims. As was anticipated, MBGS opposed this motion. The lien claims were based on a debt alleged by MBGS to be due from Liberty Star. The existence of this alleged debt was disputed.
	In March 2014 Liberty Star and Big Chunk entered into a settlement agreement with MBGS, LLC, following a resolution conference conducted in Anchorage, Alaska whereby all lien claims for the Northern Dynasty transfer were released. As a result of those claims released by MBGS, LLC, in May 2014 the company completed its loan settlement agreement with Northern Dynasty and discharged the principal balance and accrued interest for the 2010 Convertible Note which also terminated Northern Dynasty’s earn-in-rights.
	On June 1, 2011 we rented a warehouse located at Building No. 1, 7900 South Kolb Road, Tucson, Arizona 85706. We rent this warehouse space for $3,645 per month.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 31, 2015
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 HMSP. 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, 2015 and 2014, 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.
Long-lived assets and impairment of long-lived assets [Policy Text Block]	Long-lived assets and impairment of long-lived assets 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.
	We review long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Recoverability of a long-lived asset group to be held and used in operations is measured by a comparison of the carrying amount to the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset group. If such asset group is considered to be impaired, the impairment loss is measured as the amount by which the carrying amount of the asset group exceeds its fair value. Long-lived assets to be disposed of are carried at the lower of cost or fair value less the costs of disposal.
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.
Derivative liabilities [Policy Text Block]	Derivative liabilities   The valuation of the derivative liability of our warrants is determined through the use of a Monte Carlo options model that values the liability of the warrants based on a risk-neutral valuation where the price of the option is its discounted expected value. The technique applied generates a large number of possible (but random) price paths for the underlying common stock via simulation, and then calculates the associated exercise value (i.e. “payoff”) of the option for each path. These payoffs are then averaged and discounted to a current valuation date resulting in the fair value of the option.
	The valuation of the derivative liability attached to the convertible debt is arrived at through the use of a Monte Carlo model that values the derivative liability within the notes. The technique applied generates a large number of possible (but random) price paths for the underlying (or underlyings) via simulation, and then calculates the associated payment value (cash, stock, or warrants) of the derivative features. The price of the underlying common stock is modeled such that it follows a geometric Brownian motion with constant drift, and elastic volatility (increasing as stock price decreases). The stock price is determined by a random sampling from a normal distribution. Since the underlying random process is the same, for enough price paths, the value of the derivative is derived from path dependent scenarios and outcomes. The features in the notes are analyzed and incorporated into the model included the conversion features with the reset provisions, the call/redemption/prepayment options, and the default provisions. Based on these features, there are six primary events that can occur; payments are made in cash; payments are made with stock; the note holder converts upon receiving a redemption notice; the note holder converts the note; the issuer redeems the note; or the Company defaults on the note. The model simulates the underlying economic factors that influenced which of these events would occur, when they were likely to occur, and the specific terms that would be in effect at the time (i.e. stock price, conversion price, etc.). Probabilities are assigned to each variable such as redemption likelihood, default likelihood, and timing and pricing of reset events over the remaining term of the notes based on management projections. This leads to a cash flow simulation over the life of the note. A discounted cash flow for each simulation is completed, and is compared to the discounted cash flow of the note without the embedded features, thus determining a value for the derivative liability.
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.
Stock based compensation [Policy Text Block]	Stock based compensation   The Company recognizes stock-based compensation for all share-based payment awards made to employees based on the estimated fair values, using the Black-Scholes option pricing model.
	Non-employee stock-based compensation is accounted for based on the fair value of the related stock or options or the fair value of the services on the grant date, whichever is more readily determinable. The fair value of options to be granted are estimated on the date of each grant using the Black-Scholes option pricing model and amortized ratably over the option's vesting periods, which approximates the service period.
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 as of January 31, 2015 and 2014.
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 2010.
Net income (loss) per share [Policy Text Block]	Net income (loss) per share
	Basic net income (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 income (loss) per share takes into consideration shares of common stock outstanding (computed under basic income or loss per share) and potentially dilutive shares of common stock that are not anti-dilutive. For the year ended January 31, 2015, potentially dilutive shares included in the calculation of diluted net income per share included 1,345,666 shares related to warrants and 119,442,929 shares related to convertible promissory notes.  For the year ended January 31, 2014, potentially dilutive instruments were not included in the determination of diluted loss per share as their effect was 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
	During the fiscal year 2015, the Company elected to early adopt Accounting Standards Update No. 2014-10, Development Stage Entities (Topic 915): Elimination of Certain Financial Reporting Requirements. The adoption of this ASU allows the Company to remove the inception to date information and all references to exploration stage.
