Basis of Preparation | 2. Basis of Preparation a) Statement of Compliance These consolidated financial statements for the Company have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The financial statements were authorized for issue by the Board of Directors on July 27, 2018. b) Basis of Measurement The consolidated financial statements have been prepared on a historical cost basis, except certain financial instruments, which are measured at fair value, as explained in the Company’s accounting policies discussed in note 3. The consolidated financial statements are presented in Canadian dollars, which is also the parent company’s functional currency, and all values are rounded to the nearest thousand dollars, unless otherwise indicated. The preparation of consolidated financial statements in compliance with IFRS requires management to make certain critical accounting estimates. It also requires management to exercise judgment in applying the Company’s accounting policies. The areas involving a higher degree of judgment of complexity, or areas where assumptions and estimates are significant to the consolidated financial statements are disclosed in note 4. c) Basis of Consolidation These consolidated financial statements include the accounts of the Company and all of its subsidiaries, which are entities controlled by the Company. Control exists when the Company has the power to govern the financial and operating policies of an entity so as to obtain benefits from the entity’s activities. Subsidiaries are included in the consolidated financial results of the Company from the effective date of acquisition up to the effective date of disposal or loss of control. The Company’s wholly-owned subsidiaries, Bernal and Altiplano, along with various other subsidiaries, carry out their operations in Mexico, U.S.A. and in Canada. All intra-group transactions, balances, income and expenses are eliminated, in full, on consolidation. |

Summary of Significant Accounting Policies | 3. Summary of Significant Accounting Policies The accounting policies set out below were applied consistently to all periods presented in these consolidated financial statements, unless otherwise indicated. a) Foreign Currency Translation The functional currency of Starcore, the parent, is the Canadian dollar (“CAD”) and the functional currency of its subsidiaries is the United States dollar (“USD”) (collectively “Functional Currency”). Foreign currency accounts are translated into the Functional Currency as follows: • At the transaction date, each asset, liability, revenue and expense denominated in a foreign currency is translated into the Functional Currency by the use of the exchange rate in effect at that date. At the period end date, unsettled monetary assets and liabilities are translated into the Functional Currency by using the exchange rate in effect at the period end. Foreign exchange gains and losses are recognized in net earnings and presented in the Consolidated Statement of Operations and Comprehensive Income in accordance with the nature of the transactions to which the foreign currency gains and losses relate, except for foreign exchange gains and losses from translating available-for-sale b) Foreign Operations The assets and liabilities of foreign operations with Functional Currencies differing from the presentation currency, including fair value adjustments arising on acquisition, are translated to CAD at exchange rates in effect at the reporting date. The income and expenses of foreign operations with Functional Currencies differing from the presentation currency are translated into CAD at the year-to-date The Company’s foreign currency differences are recognised and presented in other comprehensive income as a foreign currency translation reserve (“Foreign Currency Translation Reserve”), a component of equity. When a foreign operation is disposed of such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. c) Cash and Cash Equivalents Cash and cash equivalents includes cash on hand, deposits held at call with financial institutions and other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and subject to an insignificant risk of change in value. At April 30, 2018 and April 30, 2017, the Company has no cash equivalents. d) Short Term Investments Short term investments, which consist of fixed term deposits held at a bank with a maturity with a maturity of more than three months at the time of issuance, are recorded at fair value. e) Revenue Recognition Revenue from the sale of metals is recognized when the significant risks and rewards of ownership have passed to the buyer, it is probable that economic benefits associated with the transaction will flow to the Company, the sale price can be measured reliably, the Company has no significant continuing involvement and the costs incurred or to be incurred in respect of the transaction can be measured reliably. Revenues from metal concentrate sales are subject to adjustment upon final settlement of metal prices, weights, and assays as of a date that may be up to two weeks after the shipment date. The Company records adjustments to revenues monthly based on quoted forward prices for the expected settlement period. Adjustments for weights and assays are recorded when results are determinable or on final settlement. Accounts receivable for metal concentrate sales are therefore measured at fair value. f) Inventory Finished goods and work-in-process Ore extracted from the mines is processed into finished goods (gold and by-products work-in-process work-in-process Supplies are measured at average cost. In the event that the net realizable value of the finished product, the production of which the supplies are held for use in, is lower than the expected cost of the finished product, the supplies are written down to net realizable value. Replacement costs of supplies are generally used as the best estimate of net realizable value. The costs of inventories sold during the year are presented in the Company’s profit and loss. g) Mining Interest, Plant and Equipment Mining interests represent capitalized expenditures related to the development of mining properties and related plant and equipment. Recognition and Measurement On initial recognition, equipment is valued at cost, being the purchase price and directly attributable cost of acquisition or construction required to bring the asset to the location and condition necessary to be capable of operating in the manner intended by the Company, including appropriate borrowing costs and the estimated present value of any future unavoidable costs of dismantling and removing items. The corresponding liability is recognized within provisions. Mining expenditures incurred either to develop new ore bodies or to develop mine areas in advance of current production are capitalized. Mine development costs incurred to maintain current production are included in the consolidated statement of operations. Exploration costs relating to the current mine in production are expensed to net income as incurred due to the immediate exploitation of these areas or an immediate determination that they are not exploitable. Borrowing costs that are directly attributable to the acquisition and preparation for use, are capitalized. Capitalization of borrowing costs, begins when expenditures are incurred and activities are undertaken to prepare the asset for its intended use. The amount of borrowing costs capitalized cannot exceed the actual amount of borrowing costs incurred during the period. All other borrowing costs are expensed as incurred. The capitalization of borrowing costs is discontinued when substantially all of the activities necessary to prepare the qualifying asset for its intended use or sale are complete. Capitalized borrowing costs are amortized over the useful life of the related asset. Major Maintenance and Repairs Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that the future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. All other repairs and maintenance are charged to the Company’s profit or loss during the financial year in which they are incurred. Subsequent Costs The cost of replacing part of an item of equipment is recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the part will flow to the Company and its costs can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day Leased Equipment Leased assets in which the Company receives substantially all of the risks and rewards of ownership of the asset are capitalized as finance leases at the lower of the fair value of the asset or the estimated present value of the minimum lease payments. The corresponding lease obligation is recorded within debt on the statement of financial position. Assets under operating leases are not capitalized and rental payments are included in earnings based on the terms of the lease. Derecognition Upon sale or abandonment, the cost of the property, plant, and equipment and related accumulated depreciation or depletion, are removed from the accounts and any gains or losses thereon are included in operations. Depreciation and Impairment Mining interest, plant and equipment are subsequently measured at cost less accumulated depreciation, less any accumulated impairment losses, with the exception of land which is not depreciated. Depletion of mine properties is charged on a unit-of-production The Company reviews and evaluates its mining interests, plant and equipment for impairment at least annually or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Impairment is considered to exist if the recoverable value of a cash generating unit is less than the carrying amount of the assets. An impairment loss is measured and recorded based on the greater of the cash generating unit’s fair value less cost to sell or its value in use versus its carrying value. Future cash flows are estimated based on expected future production, commodity prices, operating costs and capital costs. Mining interests, plant and equipment that have been impaired in prior periods are tested for possible reversal of impairment whenever events or changes in circumstances indicate that the impairment has reversed. If the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount but not beyond the carrying amount that would have been determined had no impairment loss been recognized for the asset in the prior periods. A reversal of an impairment loss is recognized in the consolidated statement of operations. h) Rehabilitation and Closure Cost Provision The Company records a provision for the estimated future costs of rehabilitation and closure of operating and inactive mines and development projects, which are discounted to net present value using the risk free interest rates applicable to the future cash outflows. Estimates of future costs represent management’s best estimates which incorporate assumptions on the effects of inflation, movements in foreign exchange rates and the effects of country and other specific risks associated with the related liabilities. The provision for the Company’s rehabilitation and closure cost obligations is accreted over time to reflect the unwinding of the discount with the accretion expense included in finance costs in the Consolidated Statement of Operations and Comprehensive Income. The provision for rehabilitation and closure cost obligations is re-measured Rehabilitation and closure cost obligations relating to operating mines and development projects are initially recorded with a corresponding increase to the carrying amounts of related mining properties. Changes to the obligations are also accounted for as changes in the carrying amounts of related mining properties, except where a reduction in the obligation is greater than the capitalized rehabilitation and closure costs, in which case, the capitalized rehabilitation and closure costs is reduced to nil and the remaining adjustment is included in production costs in the Consolidated Statement of Operations and Comprehensive Income. Rehabilitation and closure cost obligations related to inactive mines are included in production costs in the Consolidated Statement of Operations and Comprehensive Income on initial recognition and subsequently when re-measured. i) Exploration and Evaluation Expenditures Once the legal right to explore a property has been acquired, costs directly related to exploration and evaluation (“E&E”) expenditures are recognized and capitalized, in addition to the acquisition costs. These direct expenditures include such costs as materials used, surveying and sampling costs, drilling costs, payments made to contractors, geologists, consultants, and depreciation on plant and equipment during the exploration phase. Costs not directly attributable to E&E activities, including general and administrative overhead costs, are expensed in the period in which they occur. When a project is determined to no longer have commercially viable prospects to the Company, E&E expenditures in respect of that project are deemed to be impaired. As a result, those E&E expenditures, in excess of estimated recoveries, are written off to the Company’s profit or loss. The Company assesses E&E assets for impairment when facts and circumstances suggest that the carrying amount of an asset may exceed its recoverable amount. Once the technical feasibility and commercial viability of extracting the mineral resource has been determined, the property is considered to be a mine under development and is classified as “mines under construction”. E&E assets are tested for impairment before the assets are transferred to development properties. Any incidental revenues earned in connection with exploration activities are applied as a reduction to capitalized exploration costs. j) Financial Instruments Financial instruments are classified as one of the categories below based upon the purpose for which the asset was acquired. All transactions related to financial instruments are recorded on a trade date basis. The Company’s accounting policy for each category is as follows: Loans and Receivables Loans and receivables are non-derivative Amortised cost is calculated taking into account any discount or premium on acquisition and includes fees that are an integral part of the effective interest rate and transaction costs. Gains and losses are recognized in the profit or loss when the loans and receivables are derecognized or impaired, as well as through the amortization process. The Company’s cash is accounted for at fair value and amounts receivable are all accounted for as loans and receivables. Available-for-Sale Non-derivative available-for-sale. Available-for-sale available-for-sale available-for-sale Purchases and sales of available-for-sale Impairment of Financial Assets At each reporting date, the Company assesses whether there is any objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or group of financial assets is deemed to be impaired if, there is objective evidence of impairment as a result of one or more events that has occurred subsequent to the initial recognition of the asset and that event has an impact on the estimated future cash flows of the financial asset or the group of financial assets. Financial Liabilities Financial liabilities are classified as other financial liabilities, based on the purpose for which the liability was incurred, and comprised of trade and other payables, and loan payable. These liabilities are recognized at fair value, net of any transaction costs directly attributable to the issuance of the instrument and subsequently carried at amortised cost using the effective interest rate method. This ensures that, any interest expense over the period to repayment is at a constant rate on the balance of the liability carried in the statement of financial position. Interest expense in this context includes initial transaction costs and premiums payable on redemption, as well as any interest or coupon payable while the liability is outstanding. Trade and other payables & loan payable represent goods and services provided to the Company prior to the end of the period which are unpaid. Trade payable amounts are unsecured and are usually paid within 30 days of recognition. Fair value hierarchy Financial instruments recognized at fair value on the consolidated balance sheets must be classified into one of the three following fair value hierarchy levels: Level 1 – measurement based on quoted prices (unadjusted observed in active markets) for identical assets or liabilities; Level 2 – measurement based on inputs other than quoted prices included in Level 1, that are observable for the asset or liability; Level 3 – measurement based on inputs that are not observable (supported by little or no market activity) for the asset or liability. The Company’s financial instruments recognized at fair value consist of short term investments having a fair value of $Nil (2017 – $4,005) measured in accordance with Level 1. k) Income Taxes Current tax and deferred taxes are recognized in the Company’s profit or loss, except to the extent that it relates to a business combination or items recognized directly in equity or in other comprehensive loss/income. Current income taxes are recognized for the estimated taxes payable or receivable on taxable income or loss for the current year and any adjustment to income taxes payable in respect of previous years. Current income taxes are determined using tax rates and tax laws that have been enacted or substantively enacted by the period end date. Deferred tax assets and liabilities are recognized where the carrying amount of an asset or liability differs from its tax base, except for taxable temporary differences arising on the initial recognition of goodwill and temporary differences arising on the initial recognition of an asset or liability in a transaction which is not a business combination and at the time of the transaction affects neither accounting nor taxable profit or loss. Recognition of deferred tax assets for unused tax losses, tax credits and deductible temporary differences is restricted to those instances where it is probable that future taxable profit will be available against which the deferred tax asset can be utilised. At the end of each reporting period, the Company reassesses unrecognized deferred tax assets. The Company recognizes a previously unrecognized deferred tax asset to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered. l) Share Capital Financial instruments issued by the Company are classified as equity, only to the extent that they do not meet the definition of a financial liability or asset. The Company’s common shares, share warrants and share options are classified as equity instruments. Incremental costs, directly attributable to the issue of new shares, warrants or options, are shown in equity as a deduction, net of tax, from proceeds. m) Profit or Loss per Share Basic profit or loss per share is computed by dividing the Company’s profit or loss applicable to common shares by the weighted average number of common shares outstanding for the relevant period. Diluted profit or loss per share is computed by dividing the Company’s profit or loss applicable to common shares, by the sum of the weighted average number of common shares outstanding and all additional common shares that would have been outstanding if potentially dilutive instruments were converted at the beginning of the period. n) Share-based Payments Where equity-settled share options are awarded to employees or non-employees, Non-vesting non-vesting Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modifications, is charged to the Company’s profit or loss over the remaining vesting period. Where equity instruments are granted to employees, they are recorded at the fair value of the equity instrument granted at the grant date. The grant date fair value is recognized in the Company’s profit or loss over the vesting period, described as the period during which all the vesting conditions are to be satisfied. Where equity instruments are granted to non-employees, When the value of goods or services received in exchange for the share-based payment cannot be reliably estimated, the fair value is measured by use of a valuation model. The expected life used in the model is adjusted, based on management’s best estimate, for effects of non-transferability, All equity-settled share based payments are reflected in equity reserve, until exercised. Upon exercise, shares are issued from treasury and the amount reflected in equity reserve is credited to share capital, adjusted for any consideration paid. Where a grant of options is cancelled or settled during the vesting period, excluding forfeitures when vesting conditions are not satisfied, the Company immediately accounts for the cancellation as an acceleration of vesting and immediately recognizes the amount that otherwise would have been recognized for services received over the remainder of the vesting period. Any payment made to the employee on the cancellation is accounted for as the repurchase of an equity interest except to the extent that the payment exceeds the fair value of the equity instrument granted, measured at the repurchase date. Any such excess is recognized as an expense. Where vesting conditions are not satisfied and options are forfeited, the Company reverses the fair value amount of the unvested options which had been recognized over the vesting period. o) New and Revised Accounting Standards The following accounting standards have been issued or amended but are not yet effective. The Company has not early adopted these new and amended standards. The Company continues to evaluate the new standards but currently no material impact is expected as a result of the adoptions of these new and amended standards: • IFRS 3 “Business Combination” • IFRS 9 “Financial Instruments” • IFRS 10 “Consolidated Financial Statements” • IFRS 16 “Leases” • IAS 12 “Income Taxes” • IAS 23 “Borrowing Costs” • IAS 28 “Investments in Associates and Joint Ventures” • IFRIC 23 “Uncertainty over Income Tax treatments” |

Critical Accounting Estimates and Judgments | 4. Critical Accounting Estimates and Judgments The Company makes estimates and assumptions about the future that affect the reported amounts of assets and liabilities. Estimates and judgments are continually evaluated based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. In the future, actual experience may differ from these estimates and assumptions. The effect of a change in accounting estimate is recognized prospectively by including it in the Company’s profit or loss in the period of the change, if it affects that period only, or in the period of the change and future periods, if the change affects both. Information about critical judgments in applying accounting policies that have the most significant risk of causing material adjustment to the carrying amounts of assets and liabilities recognized in the consolidated financial statements within the next financial year are discussed below: a) Economic Recoverability and Profitability of Future Economic Benefits of Mining Interests Management has determined that mining interests, evaluation, development and related costs incurred which have been capitalized are economically recoverable. Management uses several criteria in its assessments of economic recoverability and probability of future economic benefit including geologic and metallurgic information, history of conversion of mineral deposits to proven and probable reserves, scoping and feasibility studies, accessible facilities, existing permits and life of mine plans. b) Impairments The Company assesses its mining interest, plant and equipment assets annually to determine whether any indication of impairment exists. Where an indicator of impairment exists, a formal estimate of the recoverable amount is made, which is considered to be the higher of the fair value less costs to sell and value in use. These assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates, future capital requirements, exploration potential and operating performance. c) Rehabilitation Provisions Rehabilitation provisions have been created based on the Company’s internal estimates. Assumptions, based on the current economic environment, have been made which management believes are a reasonable basis upon which to estimate the future liability. These estimates take into account any material changes to the assumptions that occur when reviewed regularly by management. Estimates are reviewed annually and are based on current regulatory requirements. Significant changes in estimates of contamination, restoration standards and techniques will result in changes to provisions from period to period. Actual rehabilitation costs will ultimately depend on future market prices for the rehabilitation costs, which will reflect the market condition at the time that the rehabilitation costs are actually incurred. The final cost of the currently recognized rehabilitation provision may be higher or lower than currently provided. The inflation rate applied to estimated future rehabilitation and closure costs is 3.5% and the discount rate currently applied in the calculation of the net present value of the provision is 8%. d) Income Taxes Significant judgment is required in determining the provision for income taxes. There are many transactions and calculations undertaken during the ordinary course of business for which the ultimate tax determination is uncertain. The Company recognizes liabilities and contingencies for anticipated tax audit issues based on the Company’s current understanding of tax law. For matters where it is probable that an adjustment will be made, the Company records its best estimate of the tax liability including the related interest and penalties in the current tax provision. Management believes they have adequately provided for the probable outcome of these matters; however, the final outcome may result in a materially different outcome than the amount included in the tax liabilities. In addition, the Company recognizes deferred tax assets relating to tax losses carried forward to the extent there are sufficient taxable temporary differences (deferred tax liabilities) relating to the same taxation authority and the same taxable entity against which the unused tax losses can be utilized. However, utilization of the tax losses also depends on the ability of the taxable entity to satisfy certain tests at the time the losses are recuperated. e) Share-based Payment The Company measures the cost of equity-settled transactions with employees, and some with non-employees, This estimate also requires determining the most appropriate inputs to the valuation model including the expected life of the share option, expected forfeiture rate, volatility and dividend yield and making assumptions about them. The assumptions and models used for estimating fair value for share-based payment transactions are disclosed in the notes. f) Mineral Reserves and Mineral Resource Estimates Mineral reserves are estimates of the amount of ore that can be economically and legally extracted from the Company’s mining properties. The Company estimates its mineral reserve and mineral resources based on information compiled by Qualified Persons as defined by Canadian Securities Administrators National Instrument 43-101 g) Units of production depletion Estimated recoverable reserves are used in determining the depreciation of mine specific assets. This results in depreciation charges proportional to the depletion of the anticipated remaining life of mine production. Each item’s life, which is assessed annually, has regard to both its physical life limitations and to present assessments of economically recoverable reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumption, including the amount of recoverable reserves and estimate of future capital expenditure. Changes are accounted for prospectively. |

In determining the recoverable amounts of the Company’s mining interests, the Company’s management makes estimates of the discounted future cash flows expected to be derived from the Company’s mining properties, costs to sell the mining properties and the appropriate discount rate. The projected cash flows are significantly affected by changes in assumptions about gold’s selling price, future capital expenditures, changes in the amount of recoverable reserves, resources, and exploration potential, production cost estimates, discount rates and exchange rates. Based on the calculation, at April 30, 2018, management has decided to record an impairment of $5,000 on the San Martin Project. The key assumptions used for assessing the recoverable amount are gold price of USD $1,300/oz and a discount rate of 9%. Management has also determined that the CIL plant constructed in 2016 is no longer useful in the operations of the San Martin mine in Queretaro, Mexico. While this plant has a value as a functioning carbon leach plant and has operated to process third party carbon concentrates, the Company cannot guarantee its usefulness in the future or the ability to attract third party carbon concentrates for processing. As a result, management has decided to write down the plant to $nil value and record an impairment of the book value of $1,713 to the Statements of Operations and Comprehensive Income (Loss).

Share Capital | 12. Share Capital a) Common Shares The Company is authorized to issue an unlimited number of common shares, issuable in series. The holders of common shares are entitled to one vote per share at meetings of the Company and to receive dividends, which may be declared from time-to-time. During the year ended April 30, 2018, the Company: • Completed a non-brokered one-half The Company calculated the fair value of the share component to be the lesser of the market price for the shares on the date of grant, which was $0.24 per share, and the offering price, which was $0.25 per unit. The shares, therefore, had a market price of $0.24 per share or $120 and the fair value of the warrants was calculated as the difference of $5. As such, share capital was increased by $120 and equity reserve increased by $5. During the year ended April 30, 2017, the Company did not issue any common shares. b) Warrants A summary of the Company’s outstanding share purchase warrants at April 30, 2018 and 2017 and the changes during the year ended is presented below: Number of Weighted Outstanding at April 30, 2016 139,284 $ 1.20 Warrants expired (139,284 ) 1.20 Outstanding at April 30, 2017 — — Warrants issued 250,000 0.30 Outstanding at April 30, 2018 250,000 $ 0.30 A summary of the Company’s outstanding share purchase warrants is presented below: Number of Warrants Exercise Expiry Date 250,000 $ 0.30 March 7, 2022 c) Share-based Payments The Company, in accordance with the policies of the TSX, was previously authorized to grant options to directors, officers, and employees to acquire up to 20% of the amount of stock outstanding.

The Company’s management and directors are reviewing alternative compensation arrangements for the Company’s employees and directors. The following is a summary of changes in options for the years ending April 30, 2018 and 2017: Number of Weighted Average Balance at April 30, 2016 2,846,250 $ 1.07 Forfeited/expired (1,497,500 ) 1.23 Balance at April 30, 2017 1,348,750 0.90 Forfeited (400,000 ) 0.94 Outstanding and Exercisable at April 30, 2018 948,750 $ 0.88 The following is a summary of the Company’s outstanding and exercisable options at April 30, 2018: Number Outstanding Weighted Weighted 50,000 $ 1.00 0.37 50,000 $ 0.80 0.31 50,000 $ 0.92 0.35 798,750 $ 0.88 0.71 948,750 $ 0.88 0.65 d) Deferred Share Units (“DSU”) & Restricted Share Units (“RSU”) Effective August 1, 2016, The Board of Directors has approved the adoption of a Restricted Share Unit and Deferred Share Unit Plan (the “RSU/DSU Plan”) as part of the Company’s compensation arrangements for directors, officers, employees or consultants of the Company or a related entity of the Company. Although the RSU/DSU Plan is share-based, all vested RSUs and DSUs will be settled in cash. No common shares will be issued. RSU The RSU plan is for eligible members of the Board of Directors, eligible employees and eligible contractors. The RSUs will vest over a period of three years from the date of grant, vesting as to one-third The Performance Conditions to be met are established by the Board at the time of grant of the RSU. RSUs that are permitted to be carried over to the succeeding years shall expire no later than August 1 st Number of Share Outstanding at April 30, 2016 — Granted 961,000 Cancelled (204,000 ) Outstanding at April 30, 2017 757,000 Granted 705,000 Exercised (178,750 ) Cancelled (42,000 ) Outstanding at April 30, 2018 1,241,250 Management has determined that 50% of the RSU’s will be deemed payable on the vesting dates based on current performance criteria measures. As such only 50% of the RSU’s have been valued at fair value of $0.195 per share. The liability portion for the year ended April 30, 2018 is $70 which has been included under Trades and Other Payables on the Statement of Financial Position. DSU The Company introduced a DSU plan for eligible directors. The DSUs are paid in full in the form of a lump sum payment no later than August 1 st DSU Awards going forward will vest on each anniversary date of the grant over a period of 3 years. The DSU share plan transactions during the period were as follows: Number of Share Outstanding at April 30, 2016 — Granted 760,000 Exercised (20,000 ) Cancelled (140,000 ) Outstanding at April 30, 2017 600,000 Granted 410,000 Outstanding at April 30, 2018 1,010,000 On August 1, 2017, the Company granted 410,000 DSUs to eligible directors.

Financial Instruments | 13. Financial Instruments All significant financial assets, financial liabilities and equity instruments of the Company are either recognized or disclosed in the consolidated financial statements together with other information relevant for making a reasonable assessment of future cash flows, interest rate risk and credit risk. Cash and short-term investments are carried at their fair value. There are no material differences between the carrying values and the fair values of any other financial assets or liabilities. In the normal course of business, the Company’s assets, liabilities and future transactions are impacted by various market risks, including currency risks associated with inventory, revenues, cost of sales, capital expenditures, interest earned on cash and the interest rate risk associated with floating rate debt. a) Currency Risk Currency risk is the risk to the Company’s earnings that arises from fluctuations of foreign exchange rates and the degree of volatility of these rates. The Company does not use derivative instruments to reduce its exposure to foreign currency risk. At April 30, 2018, the Company had the following financial assets and liabilities denominated in CAD and denominated in MXN$: In ‘000 of CAD MXN$ Cash $ 245 MP 8,305 Other working capital amounts—net $ (188 ) MP 44,441 At April 30, 2018, US dollar amounts were converted at a rate of $1.2821 Canadian dollars to $1 US dollar and MP were converted at a rate of MP18.78 to $1 US Dollar. A 10% increase or decrease in the US dollar exchange may increase or decrease annual earnings from mining operations by approximately $1,996. A 10% increase or decrease in the MP exchange rate will decrease or increase annual earnings from mining operations by approximately $487. b) Interest Rate Risk The Company’s cash earns interest at variable interest rates. While fluctuations in market rates do not have a material impact on the fair value of the Company’s cash flows, future cash flows may be affected by interest rate fluctuations. The Company is not significantly exposed to interest rate fluctuations and interest rate risk consists of two components: (i) To the extent that payments made or received on the Company’s monetary assets and liabilities are affected by changes in the prevailing market interest rates, the Company is exposed to interest rate cash flow risk. (ii) To the extent that changes in prevailing market interest rates differ from the interest rates in the Company’s monetary assets and liabilities, the Company is exposed to interest rate price risk. c) Credit Risk Credit risk is the risk that one party to a financial instrument will fail to discharge an obligation and cause the other party to incur a financial loss. The Company is exposed to credit risk with respect to its cash and short-term investments, the balance of which at April 30, 2018 is $2,321 (2017—$5,558) and $Nil (2017—$4,005), respectively. Cash of $974 (2017—$1,982) and short-term investments of $Nil (2017—$3,596) are held at a Mexican financial institution, cash of $23 (2017—$3) are held at a US financial institution and the remainder of $1,324 (2017—$3,573) and the short-term investment of $Nil (2017—$409) are held at a chartered Canadian financial institution; the Company is exposed to the risks of those financial institutions. The taxes receivable are comprised of Mexican VAT taxes receivable of $1,907 and GST receivable of $34, which are subject to review by the respective tax authority, and $1,359 related to amount owed from the sale of its San Pedrito Property (note 8). d) Liquidity Risk Liquidity risk arises from the excess of financial obligations over available financial assets due at any point in time. The Company’s objective in managing liquidity risk is to maintain sufficient readily available reserves in order to meet its liquidity requirements. The Company accomplishes this by achieving profitable operations and maintaining sufficient cash reserves. As at April 30, 2018, the Company was holding cash of $2,321 (2017—$5,558) and short-term investments of $Nil (2017—$4,005). Obligations due within twelve months 2018 2019 2020 2021 2022 and Trade and other payables $ 4,774 $ — $ — $ — $ — Current portion of loan payable — 1,334 — — — Reclamation and closure obligations $ — $ — $ — $ — $ 1,280 The Company’s trade and other payables are due in the short term. Long-term obligations include the Company’s reclamation and closure cost obligations, other long-term liabilities and deferred income taxes. Management believes that profits generated from the mine will be sufficient to meet its financial obligations. e) Commodity Risk Mineral prices and marketability fluctuate and any decline in mineral prices may have a negative effect on the Company. Mineral prices, particularly gold and silver prices, have fluctuated widely in recent years. The marketability and price of minerals which may be produced and sold by the Company will be affected by numerous factors beyond the control of the Company. These other factors include delivery uncertainties related to the proximity of its resources to processing facilities and extensive government regulations related to price, taxes, royalties, allowable production land tenure, the import and export of minerals and many other aspects of the mining business. Declines in mineral prices may have a negative effect on the Company. A 10% decrease or increase in metal prices may result in a decrease or increase of $2,781 in revenue and net income. |

Earnings per Share | 16. Earnings per Share The Company calculates the basic and diluted income (loss) per share using the weighted average number of shares outstanding during each year and the diluted income (loss) per share assumes that the outstanding vested stock options and share purchase warrants had been exercised at the beginning of the year. The denominator for the calculation of income (loss) per share, being the weighted average number of shares, is calculated as follows: For the years ended April 30, 2018 April 30, 2017 Issued common share, beginning of year 49,146,851 49,146,851 Weighted average issuances 73,973 — Basic weighted average common shares 49,220,824 49,146,851 Effect of dilutive warrants and options — — Diluted weighted average common shares 49,220,824 49,146,851 Vested share purchase options totalling 948,750 at April 30, 2018 (2017—1,348,750) and share purchase warrants totaling 250,000 (2017—Nil) were not included in the computation of diluted earnings per share as the effect was anti-dilutive. |

Income Taxes | 18. Income Taxes Current and deferred income tax expenses differ from the amount that would result from applying the Canadian statutory income tax rates to the Company’s earnings before income taxes. This difference is reconciled as follows: For the periods ended April 30, 2018 April 30, 2017 (Loss) Earnings before income taxes $ (17,945 ) $ 4,361 Income tax expense (recovery) at statutory rate (5,981 ) 1,134 Difference from higher statutory tax rates on earnings of foreign subsidiaries (917 ) — Permanent Difference — (1,286 ) Effect of Mexican mining royalty tax (SMD) on deferred income tax liabilities (375 ) (3,568 ) Recognition of previously unrecognized non-capital 1,328 859 Income tax (recovery) expense $ (5,945 ) $ (2,861 ) In September 2017, the British Columbia (BC) Provincial Government of Canada proposed changes to the general corporate income tax rate to increase the rate from 11% to 12% effective January 1, 2018 and onwards. This change in tax rate was substantively enacted on October 26, 2017. The relevant deferred tax balances have been measured to reflect the increase in the Company’s combined Federal and Provincial (BC) general corporate income tax rate from 26% to 27%. The significant components of the Company’s deferred income tax assets and liabilities are as follows: April 30, 2018 April 30, 2017 Deferred income tax assets (liabilities): Mining interest, plant and equipment $ (4,235 ) $ (7,805 ) Payments to defer (172 ) (31 ) Insurance (14 ) (14 ) Reclamation and closure costs provision 956 1,018 Exploration assets (368 ) (346 ) Expenses reserve 255 146 Pension-fund reserve 200 121 Deferred mining tax (1,193 ) (1,670 ) Non-capital 5,316 4,682 Sale on San Pedrito — (2,138 ) Other (748 ) (723 ) Deferred income tax liabilities, net $ (3 ) $ (6,460 ) April 30, 2018 April 30, 2017 Non-Capital losses $ 7,580 $ 19,375 Property and equipment — 1,585 Exploration and evaluation assets 22,497 30,077 $ 30,077 $ 24,637 The Non-Capital losses are set to expire between 2026 and 2038 while the remaining loss carry forwards have no set expiry date. In accordance with Mexican tax law, Bernal is subject to income tax. Income tax is computed taking into consideration the taxable and deductible effects of inflation, such as depreciation calculated on restated asset values. Taxable income is increased or reduced by the effects of inflation on certain monetary assets and liabilities through an inflationary component. Mexico Tax Reform During December 2013, the 2014 Tax Reform (the “Tax Reform”) was published in Mexico’s official gazette with changes taking effect January 1, 2014. The Tax Reform included the implementation of a 7.5% Special Mining Duty (“SMD”) and a 0.5% Extraordinary Mining Duty (“EMD”). The Company has taken the position that SMD is an income tax under IAS 12 Income tax Management is currently disputing the SMD, in a joint action lawsuit with other Mexican mining companies, with the applicable Mexican government authority. Management believes that the SMD is unconstitutional and should be overturned. In accordance with IFRS reporting standards, however, the estimated effect of the SMD has been accrued to the current and deferred income tax provisions as stated above. Should the Company be successful in overturning the SMD, in whole or in part, the accrued tax liabilities stated above will be reversed to recovery of income taxes in the applicable period. |

The Company has issued 3,000,000 warrants to the bond holders, each warrant entitling the bond holders to acquire one share of Starcore at a price of $0.20, expiring on June 18, 2021. The proceeds from the sale of the Bonds will be added to general working capital. |
Summary of Significant Accoun26
Summary of Significant Accounting Policies (Policies) | 12 Months Ended |

Text block1 [abstract] | |
Foreign Currency Translation | a) Foreign Currency Translation The functional currency of Starcore, the parent, is the Canadian dollar (“CAD”) and the functional currency of its subsidiaries is the United States dollar (“USD”) (collectively “Functional Currency”). Foreign currency accounts are translated into the Functional Currency as follows: • At the transaction date, each asset, liability, revenue and expense denominated in a foreign currency is translated into the Functional Currency by the use of the exchange rate in effect at that date. At the period end date, unsettled monetary assets and liabilities are translated into the Functional Currency by using the exchange rate in effect at the period end. Foreign exchange gains and losses are recognized in net earnings and presented in the Consolidated Statement of Operations and Comprehensive Income in accordance with the nature of the transactions to which the foreign currency gains and losses relate, except for foreign exchange gains and losses from translating available-for-sale |
Foreign Operations | b) Foreign Operations The assets and liabilities of foreign operations with Functional Currencies differing from the presentation currency, including fair value adjustments arising on acquisition, are translated to CAD at exchange rates in effect at the reporting date. The income and expenses of foreign operations with Functional Currencies differing from the presentation currency are translated into CAD at the year-to-date The Company’s foreign currency differences are recognised and presented in other comprehensive income as a foreign currency translation reserve (“Foreign Currency Translation Reserve”), a component of equity. When a foreign operation is disposed of such that control, significant influence or joint control is lost, the cumulative amount in the translation reserve related to that foreign operation is reclassified to profit or loss as part of the gain or loss on disposal. |
Cash and Cash Equivalents | c) Cash and Cash Equivalents Cash and cash equivalents includes cash on hand, deposits held at call with financial institutions and other short-term, highly liquid investments with original maturities of three months or less that are readily convertible to known amounts of cash and subject to an insignificant risk of change in value. At April 30, 2018 and April 30, 2017, the Company has no cash equivalents. |
Short Term Investments | d) Short Term Investments Short term investments, which consist of fixed term deposits held at a bank with a maturity with a maturity of more than three months at the time of issuance, are recorded at fair value. |
Revenue Recognition | e) Revenue Recognition Revenue from the sale of metals is recognized when the significant risks and rewards of ownership have passed to the buyer, it is probable that economic benefits associated with the transaction will flow to the Company, the sale price can be measured reliably, the Company has no significant continuing involvement and the costs incurred or to be incurred in respect of the transaction can be measured reliably. Revenues from metal concentrate sales are subject to adjustment upon final settlement of metal prices, weights, and assays as of a date that may be up to two weeks after the shipment date. The Company records adjustments to revenues monthly based on quoted forward prices for the expected settlement period. Adjustments for weights and assays are recorded when results are determinable or on final settlement. Accounts receivable for metal concentrate sales are therefore measured at fair value. |
Inventory | f) Inventory Finished goods and work-in-process Ore extracted from the mines is processed into finished goods (gold and by-products work-in-process work-in-process Supplies are measured at average cost. In the event that the net realizable value of the finished product, the production of which the supplies are held for use in, is lower than the expected cost of the finished product, the supplies are written down to net realizable value. Replacement costs of supplies are generally used as the best estimate of net realizable value. The costs of inventories sold during the year are presented in the Company’s profit and loss. |
Mining Interest, Plant and Equipment | g) Mining Interest, Plant and Equipment Mining interests represent capitalized expenditures related to the development of mining properties and related plant and equipment. Recognition and Measurement On initial recognition, equipment is valued at cost, being the purchase price and directly attributable cost of acquisition or construction required to bring the asset to the location and condition necessary to be capable of operating in the manner intended by the Company, including appropriate borrowing costs and the estimated present value of any future unavoidable costs of dismantling and removing items. The corresponding liability is recognized within provisions. Mining expenditures incurred either to develop new ore bodies or to develop mine areas in advance of current production are capitalized. Mine development costs incurred to maintain current production are included in the consolidated statement of operations. Exploration costs relating to the current mine in production are expensed to net income as incurred due to the immediate exploitation of these areas or an immediate determination that they are not exploitable. Borrowing costs that are directly attributable to the acquisition and preparation for use, are capitalized. Capitalization of borrowing costs, begins when expenditures are incurred and activities are undertaken to prepare the asset for its intended use. The amount of borrowing costs capitalized cannot exceed the actual amount of borrowing costs incurred during the period. All other borrowing costs are expensed as incurred. The capitalization of borrowing costs is discontinued when substantially all of the activities necessary to prepare the qualifying asset for its intended use or sale are complete. Capitalized borrowing costs are amortized over the useful life of the related asset. Major Maintenance and Repairs Subsequent costs are included in the asset’s carrying amount or recognized as a separate asset, as appropriate, only when it is probable that the future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably. All other repairs and maintenance are charged to the Company’s profit or loss during the financial year in which they are incurred. Subsequent Costs The cost of replacing part of an item of equipment is recognized in the carrying amount of the item if it is probable that the future economic benefits embodied within the part will flow to the Company and its costs can be measured reliably. The carrying amount of the replaced part is derecognized. The costs of the day-to-day Leased Equipment Leased assets in which the Company receives substantially all of the risks and rewards of ownership of the asset are capitalized as finance leases at the lower of the fair value of the asset or the estimated present value of the minimum lease payments. The corresponding lease obligation is recorded within debt on the statement of financial position. Assets under operating leases are not capitalized and rental payments are included in earnings based on the terms of the lease. Derecognition Upon sale or abandonment, the cost of the property, plant, and equipment and related accumulated depreciation or depletion, are removed from the accounts and any gains or losses thereon are included in operations. Depreciation and Impairment Mining interest, plant and equipment are subsequently measured at cost less accumulated depreciation, less any accumulated impairment losses, with the exception of land which is not depreciated. Depletion of mine properties is charged on a unit-of-production The Company reviews and evaluates its mining interests, plant and equipment for impairment at least annually or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Impairment is considered to exist if the recoverable value of a cash generating unit is less than the carrying amount of the assets. An impairment loss is measured and recorded based on the greater of the cash generating unit’s fair value less cost to sell or its value in use versus its carrying value. Future cash flows are estimated based on expected future production, commodity prices, operating costs and capital costs. Mining interests, plant and equipment that have been impaired in prior periods are tested for possible reversal of impairment whenever events or changes in circumstances indicate that the impairment has reversed. If the impairment has reversed, the carrying amount of the asset is increased to its recoverable amount but not beyond the carrying amount that would have been determined had no impairment loss been recognized for the asset in the prior periods. A reversal of an impairment loss is recognized in the consolidated statement of operations. |
Rehabilitation and Closure Cost Provision | h) Rehabilitation and Closure Cost Provision The Company records a provision for the estimated future costs of rehabilitation and closure of operating and inactive mines and development projects, which are discounted to net present value using the risk free interest rates applicable to the future cash outflows. Estimates of future costs represent management’s best estimates which incorporate assumptions on the effects of inflation, movements in foreign exchange rates and the effects of country and other specific risks associated with the related liabilities. The provision for the Company’s rehabilitation and closure cost obligations is accreted over time to reflect the unwinding of the discount with the accretion expense included in finance costs in the Consolidated Statement of Operations and Comprehensive Income. The provision for rehabilitation and closure cost obligations is re-measured Rehabilitation and closure cost obligations relating to operating mines and development projects are initially recorded with a corresponding increase to the carrying amounts of related mining properties. Changes to the obligations are also accounted for as changes in the carrying amounts of related mining properties, except where a reduction in the obligation is greater than the capitalized rehabilitation and closure costs, in which case, the capitalized rehabilitation and closure costs is reduced to nil and the remaining adjustment is included in production costs in the Consolidated Statement of Operations and Comprehensive Income. Rehabilitation and closure cost obligations related to inactive mines are included in production costs in the Consolidated Statement of Operations and Comprehensive Income on initial recognition and subsequently when re-measured. |
Exploration and Evaluation Expenditures | i) Exploration and Evaluation Expenditures Once the legal right to explore a property has been acquired, costs directly related to exploration and evaluation (“E&E”) expenditures are recognized and capitalized, in addition to the acquisition costs. These direct expenditures include such costs as materials used, surveying and sampling costs, drilling costs, payments made to contractors, geologists, consultants, and depreciation on plant and equipment during the exploration phase. Costs not directly attributable to E&E activities, including general and administrative overhead costs, are expensed in the period in which they occur. When a project is determined to no longer have commercially viable prospects to the Company, E&E expenditures in respect of that project are deemed to be impaired. As a result, those E&E expenditures, in excess of estimated recoveries, are written off to the Company’s profit or loss. The Company assesses E&E assets for impairment when facts and circumstances suggest that the carrying amount of an asset may exceed its recoverable amount. Once the technical feasibility and commercial viability of extracting the mineral resource has been determined, the property is considered to be a mine under development and is classified as “mines under construction”. E&E assets are tested for impairment before the assets are transferred to development properties. Any incidental revenues earned in connection with exploration activities are applied as a reduction to capitalized exploration costs. |
Financial Instruments | j) Financial Instruments Financial instruments are classified as one of the categories below based upon the purpose for which the asset was acquired. All transactions related to financial instruments are recorded on a trade date basis. The Company’s accounting policy for each category is as follows: Loans and Receivables Loans and receivables are non-derivative Amortised cost is calculated taking into account any discount or premium on acquisition and includes fees that are an integral part of the effective interest rate and transaction costs. Gains and losses are recognized in the profit or loss when the loans and receivables are derecognized or impaired, as well as through the amortization process. The Company’s cash is accounted for at fair value and amounts receivable are all accounted for as loans and receivables. Available-for-Sale Non-derivative available-for-sale. Available-for-sale available-for-sale available-for-sale Purchases and sales of available-for-sale Impairment of Financial Assets At each reporting date, the Company assesses whether there is any objective evidence that a financial asset or a group of financial assets is impaired. A financial asset or group of financial assets is deemed to be impaired if, there is objective evidence of impairment as a result of one or more events that has occurred subsequent to the initial recognition of the asset and that event has an impact on the estimated future cash flows of the financial asset or the group of financial assets. Financial Liabilities Financial liabilities are classified as other financial liabilities, based on the purpose for which the liability was incurred, and comprised of trade and other payables, and loan payable. These liabilities are recognized at fair value, net of any transaction costs directly attributable to the issuance of the instrument and subsequently carried at amortised cost using the effective interest rate method. This ensures that, any interest expense over the period to repayment is at a constant rate on the balance of the liability carried in the statement of financial position. Interest expense in this context includes initial transaction costs and premiums payable on redemption, as well as any interest or coupon payable while the liability is outstanding. Trade and other payables & loan payable represent goods and services provided to the Company prior to the end of the period which are unpaid. Trade payable amounts are unsecured and are usually paid within 30 days of recognition. Fair value hierarchy Financial instruments recognized at fair value on the consolidated balance sheets must be classified into one of the three following fair value hierarchy levels: Level 1 – measurement based on quoted prices (unadjusted observed in active markets) for identical assets or liabilities; Level 2 – measurement based on inputs other than quoted prices included in Level 1, that are observable for the asset or liability; Level 3 – measurement based on inputs that are not observable (supported by little or no market activity) for the asset or liability. The Company’s financial instruments recognized at fair value consist of short term investments having a fair value of $Nil (2017 – $4,005) measured in accordance with Level 1. |
Income Taxes | k) Income Taxes Current tax and deferred taxes are recognized in the Company’s profit or loss, except to the extent that it relates to a business combination or items recognized directly in equity or in other comprehensive loss/income. Current income taxes are recognized for the estimated taxes payable or receivable on taxable income or loss for the current year and any adjustment to income taxes payable in respect of previous years. Current income taxes are determined using tax rates and tax laws that have been enacted or substantively enacted by the period end date. Deferred tax assets and liabilities are recognized where the carrying amount of an asset or liability differs from its tax base, except for taxable temporary differences arising on the initial recognition of goodwill and temporary differences arising on the initial recognition of an asset or liability in a transaction which is not a business combination and at the time of the transaction affects neither accounting nor taxable profit or loss. Recognition of deferred tax assets for unused tax losses, tax credits and deductible temporary differences is restricted to those instances where it is probable that future taxable profit will be available against which the deferred tax asset can be utilised. At the end of each reporting period, the Company reassesses unrecognized deferred tax assets. The Company recognizes a previously unrecognized deferred tax asset to the extent that it has become probable that future taxable profit will allow the deferred tax asset to be recovered. |
Share Capital | l) Share Capital Financial instruments issued by the Company are classified as equity, only to the extent that they do not meet the definition of a financial liability or asset. The Company’s common shares, share warrants and share options are classified as equity instruments. Incremental costs, directly attributable to the issue of new shares, warrants or options, are shown in equity as a deduction, net of tax, from proceeds. |
Profit or Loss per Share | m) Profit or Loss per Share Basic profit or loss per share is computed by dividing the Company’s profit or loss applicable to common shares by the weighted average number of common shares outstanding for the relevant period. Diluted profit or loss per share is computed by dividing the Company’s profit or loss applicable to common shares, by the sum of the weighted average number of common shares outstanding and all additional common shares that would have been outstanding if potentially dilutive instruments were converted at the beginning of the period. |
Share-based Payments | n) Share-based Payments Where equity-settled share options are awarded to employees or non-employees, Non-vesting non-vesting Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modifications, is charged to the Company’s profit or loss over the remaining vesting period. Where equity instruments are granted to employees, they are recorded at the fair value of the equity instrument granted at the grant date. The grant date fair value is recognized in the Company’s profit or loss over the vesting period, described as the period during which all the vesting conditions are to be satisfied. Where equity instruments are granted to non-employees, When the value of goods or services received in exchange for the share-based payment cannot be reliably estimated, the fair value is measured by use of a valuation model. The expected life used in the model is adjusted, based on management’s best estimate, for effects of non-transferability, All equity-settled share based payments are reflected in equity reserve, until exercised. Upon exercise, shares are issued from treasury and the amount reflected in equity reserve is credited to share capital, adjusted for any consideration paid. Where a grant of options is cancelled or settled during the vesting period, excluding forfeitures when vesting conditions are not satisfied, the Company immediately accounts for the cancellation as an acceleration of vesting and immediately recognizes the amount that otherwise would have been recognized for services received over the remainder of the vesting period. Any payment made to the employee on the cancellation is accounted for as the repurchase of an equity interest except to the extent that the payment exceeds the fair value of the equity instrument granted, measured at the repurchase date. Any such excess is recognized as an expense. Where vesting conditions are not satisfied and options are forfeited, the Company reverses the fair value amount of the unvested options which had been recognized over the vesting period. |
New and Revised Accounting Standards | o) New and Revised Accounting Standards The following accounting standards have been issued or amended but are not yet effective. The Company has not early adopted these new and amended standards. The Company continues to evaluate the new standards but currently no material impact is expected as a result of the adoptions of these new and amended standards: • IFRS 3 “Business Combination” • IFRS 9 “Financial Instruments” • IFRS 10 “Consolidated Financial Statements” • IFRS 16 “Leases” • IAS 12 “Income Taxes” • IAS 23 “Borrowing Costs” • IAS 28 “Investments in Associates and Joint Ventures” • IFRIC 23 “Uncertainty over Income Tax treatments” |
