Accounting Policies [Abstract]
NATURE OF BUSINESS AND BASIS OF PRESENTATION AND LIQUIDITY	1. NATURE OF BUSINESS AND BASIS OF PRESENTATION AND LIQUIDITY: I-Minerals Inc. (the “Company”) was incorporated under the laws of British Columbia, Canada, in 1984. The Company is listed for trading on the TSX Venture Exchange under the symbol “IMA” and the OTCQX marketplace under the symbol “IMAHF”. The Company’s principal business is the development of the Helmer-Bovill industrial mineral property (“the Property”) located in Latah County, Idaho. The Helmer-Bovill property is comprised of eleven mineral leases that host potentially economic deposits of feldspar, quartz and kaolinitic clays, primarily kaolinite and halloysite. Basis of Presentation and Liquidity The accompanying unaudited condensed consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information as well as Article 10 of Regulation S-X on the basis that the Company will continue as a going concern, which assumes that the Company will be able to meet its obligations and continue its operations for the next year Realization values may be substantially different from carrying values as shown and these financial statements do not give effect to adjustments that would be necessary to the carrying values and classification of assets and liabilities should the Company be unable to continue as a going concern. At January 31, 2017, the Company had not yet achieved profitable operations, had an accumulated deficit of $ since inception and expects to incur further losses in the development of its business, all of which casts substantial doubt upon the Company’s ability to continue as a going concern and, therefore, that it may be unable to realize its assets and discharge its liabilities in the normal course of business. The Company’s ability to continue as a going concern is dependent upon its ability to obtain the necessary financing to develop the Property and to meet its obligations and repay its liabilities arising from normal business operations when they come due. Although the Company has been successful in the past in obtaining financing, there is no assurance that it will be able to obtain adequate financing in the future or that such financing will be on terms advantageous to the Company. The Company is currently receiving funds from a company controlled by a director of the Company through promissory notes (Notes 5 and 11). The financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of our management, all adjustments (consisting of only normal recurring accruals) considered necessary for a fair presentation of the interim financial statements have been included. Operating results for the nine months ended January 31, 2017 are not necessarily indicative of the results that may be expected for the full year ending April 30, 2017. All amounts presented are in US dollars except where otherwise indicated. For further information refer to the financial statements and footnotes thereto for the year ended April 30, 2016 included in the Company’s Annual Report on Form 10-K filed on July 27, 2016.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Financial Instruments and Fair Value Measures The book value of cash, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of those instruments. The fair value hierarchy under US GAAP is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 - observable inputs other than Level I, quoted prices for similar assets or liabilities in active prices whose inputs are observable or whose significant value drivers are observable; and Level 3 - assets and liabilities whose significant value drivers are unobservable by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s Promissory Notes are based on Level 2 inputs in the ASC 820 fair value hierarchy. The Company calculated the fair value of these instruments by discounting future cash flows using rates representative of current borrowing rates. At January 31, 2017, the Promissory Notes had a fair value of $13,616,576 (April 30, 2016 – $10,703,836). The Company had certain Level 3 liabilities required to be recorded at fair value on a recurring basis in accordance with US GAAP as at January 31, 2017 and April 30, 2016. As at January 31, 2017, the Company’s Level 3 liabilities consisted of the warrants issued in connection with the Company’s offering of equity units in a private placement and warrants issued as financing fees as well as the grant of share purchase options to non-employees. The resulting Level 3 liabilities have no active market and are required to be measured at their fair value each reporting period based on information that is unobservable. A summary of the Company’s Level 3 liabilities for the nine months ended January 31, 2017 and 2016 is as follows: 2017 $ 2016 $ Warrants (Note 6) Beginning fair value 326,595 1,128,841 Issuance 55,239 151,318 Reallocation on exercises of warrants (108,784) - Change in fair value 365,241 (631,185) Ending fair value 638,291 648,974 Non-employee options (Note 7(c)) Beginning fair value 189,207 116,615 Fair value of options on vesting - 42,933 Change in fair value 139,185 (28,502) Ending fair value 328,392 131,046 Total Level 3 liabilities 966,683 780,020 Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). There were no assets or liabilities measured at fair value on a nonrecurring basis during the periods ended January 31, 2017 and April 30, 2016. Earnings (Loss) Per Share The basic loss per common share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding. Diluted loss per common share is computed similar to basic loss per common share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For the nine months ended January 31, 2017, loss per share excludes 9,226,082 (2016 – 30,414,438) potentially dilutive common shares (related to outstanding options and warrants as well as shares committed to be issued pursuant to the Promissory Notes) as their effect was anti-dilutive .

The First Promissory Notes were to mature as to $3,000,000 on December 2, 2016 and the balance due on December 31, 2016. On February 18, 2015 and December 1, 2015, the Company entered into agreements with the Lender pursuant to which $5,457,000 was advanced to the Company in tranches (the “Second Promissory Notes”). The Second Promissory Notes mature were to mature as to $1,000,000 on December 2, 2016, $2,000,000 on June 2, 2017 and the balance due on December 2, 2017. Effective August 31, 2016, the Company entered into an agreement (dated June 1, 2016) with the Lender pursuant to which up to an additional $2,965,000 will be advanced to the Company in tranches (the “Third Promissory Notes”). In addition, the First Promissory Notes and the Second Promissory Notes were amended and combined with the Third Promissory Notes with a modified maturity date of December 2, 2017. All other terms of the First Promissory Notes and the Second Promissory Notes remained unchanged. In accordance with the guidance of ASC 470-50 and ASC 470-60, the Company determined that the June 1, 2016 agreement resulted in a debt modification, not a debt extinguishment or a troubled debt restructuring. The aggregate finance fees relating to the promissory notes are now being amortized to the Statement of Loss over the revised life of the promissory notes using the effective interest method. During the nine months ended January 31, 2017, the Company received $1,420,000 in advances pursuant to the Third Promissory Notes and the final $200,000 in advances pursuant to the Second Promissory Notes. The following table outlines the estimated cash payments required in order to repay the principal balance of the Third Promissory Notes: 2017 $ 2018 $ 2019 $ 2020 $ 2021 $ Total $ - 14,063,657 - - - 14,063,657 Certain conditions may result in early repayment including immediate repayment in the event a person currently not related to the Company acquires more than 40% of the outstanding common shares of the Company. Debt issuance costs will be amortized over the estimated maturity life of the promissory notes. The promissory notes bear interest at the rate of 12% per annum and during the nine months ended January 31, 2017, the Company recorded interest of $1,159,725 (2016 - $525,136). Interest is payable semi-annually as calculated on May 31 st th The Company and the Lender agreed that the Lender is to receive bonus shares equal to 7.5% of each loan tranche advanced divided by the Company’s common share market price. In addition, the Company will issue the Lender an equal number of share purchase warrants for each loan tranche advanced. Each bonus share purchase warrant will entitle the Lender to purchase one common share of the Company at a price equal to the greater of (a) the market price of the Company’s common shares on the date of the advance and (b) the volume weighted average price of the Company’s common shares over the twenty trading days immediately prior to the date of the advance. The bonus share purchase warrants expire on the earlier of (a) December 31, 2018 and (b) the date the advance has been repaid in full, including interest. During the nine months ended January 31, 2017, the Company issued 852,562 bonus shares to the Lender at the fair value of $200,756, based on their quoted market price at the date the advances were received, including 349,325 shares having a fair value of $81,112 that the Company had committed to issue as at April 30, 2016. At January 31, 2017, the Company was committed to issuing no additional bonus shares to the Lender. The fair value of the bonus shares was determined by reference to the trading price of the Company’s common shares on the date the advances were received. The fair value of 534,480 bonus share purchase warrants committed to be issued (based on advances received during the period) during the nine months ended January 31, 2017 of $55,239 was estimated using the The aggregate finance fees (bonus shares and bonus warrants) are recorded against the promissory notes balance and are being amortized to the Statement of Loss over the life of the promissory notes using the effective interest method. The accretion expense in respect of the debt discount recorded on the issuance of bonus shares and warrants totalled $363,386 for the nine months ended January 31, 2017 (2016 - $142,702) The unamortized debt discount as at January 31, 2017 is $396,856 (April 30, 2016 $585,359).

WARRANT LIABILITIES	6. WARRANT LIABILITIES: The Company has share purchase warrants exercisable into common shares at an exercise price denominated in Canadian dollars. As a variable amount of US dollars are exercisable into a fixed number of common shares, the share purchase warrants are classified as derivative liabilities. The Company records the fair value of the share purchase warrants in accordance with ASC 815, “Derivatives and Hedging”.

Expected volatility was determined by reference to the historical volatility of the Company’s common shares trading on the TSX Venture Exchange. Non-Employee Stock Options In accordance with the guidance of ASC 815-40-15, stock options awarded to non-employees that are fully vested and exercisable in Canadian dollars are required to be accounted for as derivative liabilities because they are considered not to be indexed to the Company’s stock due to their exercise price being denominated in a currency other than the Company’s functional currency. Stock options awarded to non-employees that are not vested are accounted for as equity awards until the terms associated with their vesting requirements have been met. As at January 31, 2017, there were 400,000 (April 30, 2016 - nil) non-employee stock option awards that had not yet vested. The non-employee stock options are accounted for at their respective fair values and are summarized as follows for the nine months ended January 31, 2017 and 2016: 2017 $ 2016 $ Fair value of non-employee options, beginning of the period 189,207 116,615 Fair value of options on vesting - 42,933 Change in fair value of non-employee stock options during the period 139,185 (28,502) Fair value of non-employee options, end of the period 328,392 131,046 The Company determined the fair value of its non-employee stock options as at January 31, 2017 and April 30, 2016 using the Black-Scholes option pricing model with the following weighted average assumptions: January 31, 2017 April 30, 2016 Stock price (CAD$) 0.39 0.23 Exercise price (CAD$) 0.23 0.23 Risk-free interest rate (%) 0.86 1.34 Expected life (years) 1.66 2.43 Expected volatility (%) 61 87 Expected dividends ($) Nil Nil The non-employee options are required to be re-valued with the change in fair value of the liability recorded as a gain or loss on the change of fair value of derivative liability and included in other items in the Company’s Consolidated Statements of Loss at the end of each reporting period. The fair value of the options will continue to be classified as a liability until such time as they are exercised, expire or there is an amendment to the respective agreements that renders these financial instruments to be no longer classified as a liability. As at , the unamortized compensation cost of options is $105,809 and the intrinsic value of options expected to vest is $729,614 (CAD$949,400).

Accounting Policies [Abstract]
Financial Instruments and Fair Value Measures	Financial Instruments and Fair Value Measures The book value of cash, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the immediate or short-term maturity of those instruments. The fair value hierarchy under US GAAP is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: Level 1 - quoted prices (unadjusted) in active markets for identical assets or liabilities; Level 2 - observable inputs other than Level I, quoted prices for similar assets or liabilities in active prices whose inputs are observable or whose significant value drivers are observable; and Level 3 - assets and liabilities whose significant value drivers are unobservable by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company’s Promissory Notes are based on Level 2 inputs in the ASC 820 fair value hierarchy. The Company calculated the fair value of these instruments by discounting future cash flows using rates representative of current borrowing rates. At January 31, 2017, the Promissory Notes had a fair value of $13,616,576 (April 30, 2016 – $10,703,836). The Company had certain Level 3 liabilities required to be recorded at fair value on a recurring basis in accordance with US GAAP as at January 31, 2017 and April 30, 2016. As at January 31, 2017, the Company’s Level 3 liabilities consisted of the warrants issued in connection with the Company’s offering of equity units in a private placement and warrants issued as financing fees as well as the grant of share purchase options to non-employees. The resulting Level 3 liabilities have no active market and are required to be measured at their fair value each reporting period based on information that is unobservable. A summary of the Company’s Level 3 liabilities for the nine months ended January 31, 2017 and 2016 is as follows: 2017 $ 2016 $ Warrants (Note 6) Beginning fair value 326,595 1,128,841 Issuance 55,239 151,318 Reallocation on exercises of warrants (108,784) - Change in fair value 365,241 (631,185) Ending fair value 638,291 648,974 Non-employee options (Note 7(c)) Beginning fair value 189,207 116,615 Fair value of options on vesting - 42,933 Change in fair value 139,185 (28,502) Ending fair value 328,392 131,046 Total Level 3 liabilities 966,683 780,020 Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances (for example, when there is evidence of impairment). There were no assets or liabilities measured at fair value on a nonrecurring basis during the periods ended January 31, 2017 and April 30, 2016.
Earnings (Loss) Per Share	Earnings (Loss) Per Share The basic loss per common share is computed by dividing net loss available to common stockholders by the weighted average number of common shares outstanding. Diluted loss per common share is computed similar to basic loss per common share except that the denominator is increased to include the number of additional common shares that would have been outstanding if the potential common shares had been issued and if the additional common shares were dilutive. For the nine months ended January 31, 2017, loss per share excludes 9,226,082 (2016 – 30,414,438) potentially dilutive common shares (related to outstanding options and warrants as well as shares committed to be issued pursuant to the Promissory Notes) as their effect was anti-dilutive.
