Disclosure Of Significant Accounting Policies [Abstract] |
Recent accounting pronouncements | Accounting standards and amendments adopted IFRS 15 – Revenue from contracts with customers IFRS 15, Revenue from Contracts with Customers, was adopted on January 1, 2018. The standard introduces a single, principles-based, five-step model for the recognition of revenue when control of goods is transferred to the customer. The five steps are: identify the contract(s) with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to each performance obligation and recognize revenue as each performance obligation is satisfied. IFRS 15 also requires enhanced disclosures about revenue to help users better understand the nature, amount, timing and uncertainty of revenue and cash flows from contracts with customers. The Company evaluated the effect the standard had on its sales recorded in its consolidated financial statements and determined there is no impact to the timing or amounts of revenue recognized in its statement of operations. IFRS 9 – Financial Instruments The final version of IFRS 9, Financial Instruments, was issued in July 2014 to replace IAS 39, Financial Instruments: Recognition and Measurement. IFRS 9 has two measurement categories for financial assets: amortized cost and fair value. Classification is determined at initial recognition in one of the following categories: fair value through profit and loss (“FVTPL”), fair value through other comprehensive income (“FVOCI”) or at amortized cost. In addition, the standard amended some of the requirements of IFRS 7, Financial Instruments: Disclosures, including the requirement for added disclosures about investments in equity instruments measured at FVOCI and guidance on financial liabilities and derecognition of financial instruments. The Company adopted the standard on January 1, 2018. Retrospective application was required, but there was no requirement to restate comparative periods disclosed. The Company has assessed the classification and measurement of its financial assets and financial liabilities under IFRS 9 and have summarized the original measurement categories under IAS 39 and the new measurement categories under IFRS 9 in the following table:
| Measurement Categories
|  | IAS 39 |  | IFRS 9
Financial instruments: |  |  |  |
Cash and cash equivalents |  | Amortized cost |  | Amortized cost
Debt service reserve account |  | Amortized cost |  | Amortized cost
Loans receivable |  | Amortized cost |  | Amortized cost
Long-term investments |  | FVTPL & FVOCI |  | FVOCI
Derivative financial instruments |  | FVTPL |  | FVTPL
Accounts payable and accrued liabilities |  | Amortized cost |  | Amortized cost
Convertible senior subordinated notes |  | FVTPL |  | FVTPL FVOCI for change in credit risk
Debt |  | Amortized cost |  | Amortized cost
Lease liabilities |  | Amortized cost |  | Amortized cost
The Company has elected to irrevocably designate its long-term investments held at the transition date as FVOCI as they are not considered to be held for trading. The Company applied the modified retrospective approach for the adoption of IFRS 9, whereby prior periods were not restated for the impact of the standard. As a result, a decrease in deficit of $46 million with a corresponding adjustment to accumulated other comprehensive loss ("AOCI") was recognized on January 1, 2018 consisting of:
• | Long-term investments (Note 7): reclassification of a $35 million loss (net of a $1 million deferred income tax recovery) from deficit to accumulated other comprehensive loss.
• | Convertible senior subordinated notes (Note 10): reclassification of an $11 million loss from deficit to AOCI.
Previously, under IAS 39, long-term investments were measured at fair value on acquisition and at each reporting date. Any unrealized holding gains and losses related to these investments were excluded from net income and included in other comprehensive income ("OCI") until the investment was sold or there was objective evidence that the investment was impaired. When there was evidence that an investment was impaired, the cumulative loss previously recognized in OCI was reclassified from AOCI to the consolidated statement of operations. For financial assets under IAS 39, the Company was required to assess whether there was objective evidence that the asset was impaired at each reporting date. If such evidence existed, the Company recognized an impairment loss equal to the difference between the amortized cost of the financial asset and the present value of the estimated future cash flows, discounted using the instrument’s original effective interest rate. The carrying amount of the asset was reduced by this amount either directly or indirectly through the use of an allowance account. Impairment losses on financial assets carried at amortized cost are reversed in subsequent periods if the amount of the loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized. The Company's approach to impairment of financial assets under IFRS 9, is outlined in Note 4. Accounting standards and amendments issued but not yet adopted IFRS 16 – Leases The IASB has issued IFRS 16, Leases, which is effective for annual periods commencing on or after January 1, 2019. This new standard eliminates the classification of leases as either operating leases or finance leases and introduces a single lessee accounting model which requires the lessee to recognize assets and liabilities for all leases with a term of longer than 12 months, with the exception of low-value assets. This requirement to record leases as finance leases is expected to increase lease assets and lease liabilities on the Company's consolidated balance sheet. IFRS 16 will also result in the lease expense previously recognized for operating leases being replaced with depreciation expense for lease assets and interest and financing expense for lease liabilities. On the transition date of January 1, 2019, the Company expects to recognize additional leases on the consolidated balance sheet, which will increase both short and long-term liabilities and mining interest balances. As a result of recognizing additional lease obligations, it is expected that there will be a reduction in production costs, as lease expense will be removed. Depreciation expense and interest and financing expense are expected to increase as a result of the recognition of additional lease assets and the associated lease obligations. The Company is in the process of finalizing the quantification of the impact. In 2017, the Company completed an initial scoping of its existing lease and service contracts and is finalizing this scoping. During 2018, a working group was formed, the assessment of the contracts began and was substantially completed, initial calculations were prepared for the contracts determined to contain leases for all locations and the design of controls for the identification of leases in service contracts was completed. In addition, during the fourth quarter of 2018, completeness tests were performed to validate the population of contracts in scope for IFRS 16. The Company intends to use the modified retrospective approach of adoption resulting in no restatement of prior year comparatives. The quantitative impact of adopting IFRS 16 will be reported in the first quarter of 2019.
Principles of consolidation | Principles of consolidation The financial statements of the Company consolidate the accounts of B2Gold and its subsidiaries. All intercompany transactions, balances, and unrealized gains and losses from intercompany transactions are eliminated on consolidation. The Company’s most significant wholly owned and partially owned subsidiaries are presented below:
|  | % interest
- | Fekola SA (“Fekola”) (Note 8) | 80
- | B2Gold Namibia (Pty) Ltd. (“Otjikoto”) | 90
- | Philippines Gold Processing & Refining Corporation (“Masbate”) | 100
- | Desarrollo Minero de Nicaragua, S.A. (“Libertad”) | 100
- | Triton Minera S.A. (“Limon”) | 100
- | Kiaka SA (“Kiaka”) | 81
Subsidiaries are entities controlled by the Company. Control exists when the Company has power over an investee, when the Company is exposed, or has rights, to variable returns from the investee and when the Company has the ability to affect those returns through its power over the investee. Subsidiaries are fully consolidated from the date on which control is obtained by B2Gold and are de-consolidated from the date that control ceases. The Company’s Gramalote property located in Colombia operates as an incorporated joint venture with AngloGold Ashanti Limited (“AngloGold”) which is accounted for as a jointly controlled entity (“JCE”). The Company does not control, either directly or indirectly, this JCE. B2Gold accounts for its interest in this JCE using the equity method. The Company established a trust arrangement under its Incentive Plan (Note 12) for the benefit of its directors, officers, employees and service providers. The Company consolidates this trust as it has the power to control its financial and operating policies and obtain the benefits from its activities.
Business combinations | Business combinations A business combination requires that the assets acquired and liabilities assumed constitute a business. A business consists of inputs and processes applied to those inputs that have the ability to create outputs. Although businesses usually have outputs, outputs are not required for an integrated set to qualify as a business as the Company considers other factors to determine whether the set of activities or assets is a business. Business combinations are accounted for using the acquisition method whereby acquired assets and liabilities are recorded at fair value as of the date of acquisition with the excess of the purchase consideration over such fair value being recorded as goodwill. Non-controlling interest in an acquisition may be measured at either fair value or at the non-controlling interest’s proportionate share of the fair value of the acquiree’s net identifiable assets. The excess of (i) total consideration transferred by the Company, measured at fair value, including contingent consideration, and (ii) the non-controlling interests in the acquiree’s, over the acquisition-date fair value of the net of the assets acquired and liabilities assumed, is recorded as goodwill. If the fair value attributable to the Company’s share of the identifiable net assets exceeds the cost of acquisition, the difference is recognized as a gain in the consolidated statement of operations. Should the consideration be contingent on future events, the preliminary cost of the acquisition recorded includes management’s best estimate of the fair value of the contingent amounts expected to be payable. Provisional fair values allocated at the reporting date are finalized within one year of the acquisition date with retroactive restatement to the acquisition date as required. Transaction costs, other than those associated with the issue of debt or equity securities, which the Company incurs in connection with a business combination, are expensed as incurred.
Goodwill | Goodwill Goodwill arising on the Company’s acquisitions includes (but is not limited to): (i) the ability of the Company to capture certain synergies through management of the acquired operation within the Company; (ii) the potential to increase reserves and resources through exploration activities; and (iii) the requirement to record a deferred tax liability for the difference between the assigned fair values and the tax bases of assets acquired and liabilities assumed. Goodwill is not amortized. The Company performs an annual impairment test for goodwill and when events or changes in circumstances indicate that the related carrying amount may not be recoverable. If the carrying amount of a cash generating unit (“CGU”) to which goodwill has been allocated exceeds the recoverable amount, an impairment loss is recognized for the amount in excess. The impairment loss is allocated first to reduce the carrying amount of goodwill allocated to the CGU to $nil and then to the other assets of the CGU based on the relative carrying amounts of those assets. Impairment losses recognized for goodwill are not reversed in subsequent periods should its value recover. Goodwill is allocated to CGUs for the purpose of impairment testing. The allocation is made to those cash generating units or groups of CGUs that are expected to benefit from the business combination in which the goodwill arose. If the composition of one or more cash generating units to which goodwill has been allocated changes due to a reorganization, the goodwill is re-allocated to the units affected.
Investments in joint arrangements | Investments in joint arrangements A joint arrangement is a contractual arrangement whereby two or more parties undertake an economic activity that is subject to joint control. Joint control is the contractually agreed sharing of control such that significant operating and financial decisions require the unanimous consent of the parties sharing control. The Company’s joint arrangements consist of jointly controlled entities (involving the establishment of a corporation) and are accounted for using the equity method. The equity method involves recording the initial investment at cost. Additional funding into an investee is recorded as an increase in the carrying value of the investment. The carrying amount is adjusted by the Company’s share of post-acquisition net income or loss, dilution gains or losses, depreciation, amortization or impairment.
Foreign currency translation | Foreign currency translation Functional and presentation currency Items included in the financial statements of each of the group’s entities are measured using the currency of the primary economic environment in which the entity operates (“the functional currency”). The consolidated financial statements are presented in United States dollars, which is the group’s presentation currency. The Company’s mining operations operate primarily within an economic environment where the functional currency is the United States dollar. Transactions and balances Transactions denominated in foreign currencies are translated into the United States dollar as follows:
• | Monetary assets and liabilities are translated at the rates of exchange at the consolidated balance sheet date;
• | Non-monetary assets and liabilities are translated at historical exchange rates prevailing at each transaction date;
• | Revenue and expenses are translated at the exchange rate at the date of the transaction, except depreciation, depletion and amortization, which are translated at historical exchange rates, and share-based compensation expense, which is translated at the rates of exchange applicable at the date of grant of the share-based compensation; and
• | Exchange gains and losses on translation are included in earnings. When the gain or loss on certain non-monetary items, such as long-term investments classified as fair value through other comprehesive income (“OCI”) is recognized in OCI, the translation differences are also recognized in OCI.
Group companies For any subsidiaries or joint ventures whose functional currency differs from the United States dollar, foreign currency balances and transactions are translated into the United States dollar as follows:
• | Assets and liabilities are translated at the rates of exchange at the consolidated balance sheet date;
• | Revenue and expenses are translated at average exchange rates throughout the reporting period or at rates that approximate the actual exchange rates; items such as depreciation are translated at the monthly average exchange rate; and
• | Exchange gains and losses on translation are included in OCI.
The exchange gains and losses are recognized in earnings upon the substantial disposition, liquidation or closure of the entity that gave rise to such amounts.
Financial instruments | Financial instruments The following financial instruments accounting policies have been applied as of January 1, 2018 upon adoption of IFRS 9. Prior to January 1, 2018, the Company applied financial instruments policies aligned with IAS 39, Financial Instruments Recognition and Measurement. The impact of IFRS 9 and key accounting policies under IAS 39 are outlined in Note 3. The Company recognizes financial assets and liabilities on the balance sheet when the Company becomes party to the contractual provisions of the instrument. Cash and cash equivalents Cash and cash equivalents include cash on hand, deposits held with banks, and other short-term highly liquid investments with original maturities of three months or less. Cash and cash equivalents are classified as financial assets and subsequently measured at amortized cost. Accounts receivable, accounts payable and accrued liabilities Accounts receivable, accounts payable and accrued liabilities are non-interest bearing and are initially measured at fair value, subsequently recorded at amortized cost which approximates fair value due to the short term to maturity. Where necessary, accounts receivable are net of expected credit losses. Accounts receivable are classified as financial assets subsequently measured at amortized cost and accounts payable and accrued liabilities are classified as financial liabilities subsequently measured at amortized cost. Long-term investments Equity investments in entities that are not subsidiaries, joint ventures or investments in associates are designated FVTPL unless they are irrevocably designated, on an individual basis, as FVOCI. These investments are measured at fair value on acquisition and at each reporting date. Any unrealized holding gains and losses related to long-term investments designated as FVOCI are excluded from net earnings and are included in OCI. Upon disposal, any accumulated gains and losses remain in equity. Lease liabilities Lease liabilities are interest bearing and are initially measured at the present value and subsequently recorded at amortized cost. Debt The Company initially recognizes all financial liabilities at fair value and classifies them as subsequently measured at either FVTPL or amortized cost, as appropriate. For debt subsequently measured at amortized cost, the effective interest rate method is used. Debt classified as FVTPL is measured at fair value on each financial period-end date with gains and losses flowing through the statement of operations. For debt that is optionally classified as FVTPL, the part of the fair value change related to the Company’s own credit risk is recorded in OCI rather than the statement of operations. Derivative instruments Derivative instruments, including embedded derivatives, are recorded at FVTPL and accordingly recorded on the balance sheet date at fair value. Unrealized gains and losses on derivatives held for trading are recorded as part of other gains or losses in earnings. Fair values for derivative instruments are determined using valuation techniques, using assumptions based on market conditions existing at the balance sheet date.
Impairment of financial assets | Impairment of financial assets At each reporting date, the Company measures the loss allowance for the financial asset held at amortized cost at an amount equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly since initial recognition. If at the reporting date, the credit risk on the financial asset has not increased significantly since initial recognition, we measure the loss allowance for the financial asset at an amount equal to twelve month expected credit losses. Derecognition of financial assets Financial assets are derecognized when the investments mature or are sold, and substantially all the risks and rewards of ownership have been transferred. Gains and losses on derecognition of financial assets classified as FVTPL or amortized cost are recognized within other non-operating income. Accumulated gains or losses on financial assets classified as FVOCI remain within accumulated other comprehensive income.
Inventories | Inventories Gold and silver bullion, in-process and stockpile inventories are recorded at the lower of average cost and net realizable value. The cost of finished goods and work-in-progress comprises raw materials, direct labour, and other direct costs, as well as stripping in the production stage and related production overheads (based on normal operating capacity) including applicable depreciation on property, plant and equipment. Net realizable value is the estimated selling price less applicable selling expenses. When inventories have been written down to net realizable value, a new assessment of net realizable value is made in each subsequent period. When the circumstances that caused the write down no longer exist, the amount of the write down is reversed. Materials and supplies inventories are valued at the lower of average cost and net realizable value. Cost includes acquisition, freight and other directly attributable costs.
Mining interests | Mining interests Mining interests include property, plant and equipment, mineral properties and mine development costs, deferred stripping, exploration and evaluation expenditures, capitalized borrowing costs and impairment. Property, plant and equipment Property, plant and equipment are recorded at cost. Repairs and maintenance expenditures are charged to operations; major improvements and replacements which extend the useful life of an asset are capitalized. Property, plant and equipment are amortized over the life of the mine using the units-of-production (“UOP”) method based on the recoverable ounces from the estimated proven and probable reserves and a portion of the measured and indicated resources that are reasonably expected to be converted to proven and probable reserves. Mobile equipment, tailings dam and equipment are depreciated on a straight-line basis over three to six years as appropriate, net of residual value. The Company allocates the amount initially recognized in respect of an item of property, plant and equipment to its significant parts and depreciates separately each such part. Residual values, method of amortization and useful lives of the assets are reviewed annually and adjusted if appropriate. During the commissioning phase of a new mine, pre-production expenditures, net of incidental revenue, are capitalized to plant and equipment. Mineral properties and mine development costs Mineral properties and mine development costs are stated at cost less accumulated depreciation and impairment losses. When production commences, these costs are amortized using the UOP method, based on recoverable ounces from the estimated proven and probable reserves and a portion of measured and indicated resources that are reasonably expected to be converted to proven and probable reserves. Capitalization of costs incurred ceases when the mining property is capable of commencement of mining operations in the manner intended by management. Costs incurred prior to this point, including depreciation of related plant and equipment, are capitalized and proceeds from sales of ounces produced during this period are offset against capitalized costs. The Company applies judgment in its assessment of when a mine is capable of operating in the manner intended by management which takes account of the design of the mine and the nature of the initial commissioning phase of the mine. Non-recoverable costs for projects determined not to be commercially feasible are expensed in the period in which the determination is made or when the carrying value of the project is determined to be impaired. Deferred stripping Stripping costs incurred during the production phase of a mine are considered production costs and are included in the cost of inventory produced during the period in which stripping costs are incurred, unless the stripping activity can be shown to be a betterment of the mineral property. Betterment occurs when stripping activity increases future output of the mine by providing access to additional reserves. Stripping costs incurred to prepare the ore body for extraction are capitalized as mine development costs and are amortized on a UOP basis over the reserves and resources to which they relate. Exploration and Evaluation Expenditures The Company defers the cost of acquiring, maintaining its interest, exploring and developing mineral properties as exploration and evaluation until the properties are placed in production, abandoned, sold or considered to be impaired in value. Once the technical feasibility and commercial viability of the extraction of mineral reserves or resources from a particular mineral property has been determined, exploration and evaluation expenditures are reclassified to “mineral properties and mine development costs”. If no mineable ore body is discovered, such costs are expensed in the period in which it is determined the property has no future economic value. Exploration costs that do not relate to any specific property are expensed as incurred. The establishment of technical feasibility and commercial viability of a mineral property is assessed based on a combination of factors, such as but not limited to:
• | The extent to which mineral reserves or mineral resources have been identified through a feasibility study or similar level document;
• | The results of optimization studies and further technical evaluation carried out to mitigate project risks identified in the feasibility study;
• | The status of environmental permits; and
• | The status of mining leases or permits.
In addition, commercial viability is deemed to be achieved when the Company determines that the project will provide a satisfactory return relative to its perceived risks. Ore reserves and resources may be declared for an undeveloped mining project before its commercial viability has been fully determined. Evaluation costs may continue to be capitalized during the period between declaration of reserves and approval to mine as further work is undertaken in order to refine the development case to maximize the project’s returns. Borrowing costs Borrowing costs attributable to the acquisition or construction of qualifying assets that take a substantial period of time to make ready for their intended use are added to the cost of the assets, until such time as the assets are substantially complete and ready for their intended use. The amount of borrowing costs capitalized cannot exceed the actual amount of borrowing costs incurred in a period. All other borrowing costs are expensed in the period in which they are incurred. Impairment The carrying amounts of non-current assets are tested for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable. If there are indicators of impairment, the recoverable amount of the asset is estimated in order to determine the extent of the impairment. An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount and is recorded as an expense in the statement of operations. The recoverable amount is the higher of an asset’s “fair value less costs of disposal” and “value-in-use”. Where the asset does not generate cash flows that are independent from other assets, the recoverable amount of the cash-generating unit to which the asset belongs is determined. “Fair value less costs of disposal” is determined as the amount that would be obtained from the sale of the asset in an arm’s length transaction between knowledgeable and willing parties. For mining assets this would generally be determined based on the present value of the estimated future cash flows arising from the continued development, use or eventual disposal of the asset. In assessing these cash flows and discounting them to the present value, assumptions used are those that an independent market participant would consider appropriate. In assessing “value-in-use”, the estimated future cash flows expected to arise from the continuing use of the assets in their present form and from their disposal are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and risks specific to the asset. Impairment losses are evaluated for potential reversals when events or circumstances warrant such consideration. Where an impairment loss is subsequently reversed, the amount of such reversal is limited such that, the revised carrying amount of the asset or cash-generating unit does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset or cash-generating unit in the prior years. A reversal of an impairment loss is recognized into earnings immediately.
Leases | Leases The determination of whether an arrangement is, or contains, a lease is based on the substance of the arrangement at inception date. It requires consideration as to whether the fulfilment of the arrangement is dependent on the use of a specific asset or assets or the arrangement conveys a right to use the asset. A reassessment is made after inception of the lease only if one of the following applies:
(a) | There is a change in contractual terms, other than a renewal or extension of the arrangement;
(b) | A renewal option is exercised or extension granted, unless the term of the renewal or extension was initially included in the lease term;
(c) | There is a change in the determination of whether fulfilment is dependent on a specified asset; or
(d) | There is a substantial change to the asset.
Where a reassessment is made, lease accounting shall commence or cease from the date when the change in circumstances gave rise to the reassessment for scenarios (a), (c) or (d) and at the date of the renewal or extension period for scenario (b). Company as a lessee Finance leases, which transfer to the Company substantially all the risks and rewards incidental to ownership of the leased item, are capitalized at the commencement of the lease term (the date from which the lessee is entitled to exercise its right to use the leased asset) at the fair value of the leased asset or, if lower, at the present value of the minimum lease payments. Capitalized leased assets are depreciated over the shorter of the estimated useful life of the asset and the lease term, if there is no reasonable certainty that the Company will obtain ownership by the end of the lease term. A lease is classified as an operating lease if it does not transfer substantially all of the risks and rewards incidental to ownership. Operating lease payments are recognized as an expense in the statement of operations on a straight line basis over the lease term.
Mine restoration provisions | Mine restoration provisions Future obligations to retire an asset including site closure, dismantling, remediation and on-going treatment and monitoring are initially recognized and recorded as a liability based on estimated future cash flows discounted at a risk free rate. The measurement determination is based on estimated future cash flows, the current risk-free discount rate, and an estimated inflation factor. The value of restoration provisions is adjusted at each reporting period for changes to factors including the expected amount of cash flows required to discharge the liability, the timing of such cash flows and the risk-free interest rate. The liability is added to the carrying amount of the associated asset, and this additional carrying amount is depreciated over the life of the asset. The liability is accreted to full value over time through periodic charges to earnings. This unwinding of the discount is expensed in the statement of operations. As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced.
Share-based payments | Share-based payments The cost of stock options and other equity-settled share-based payment arrangements is recorded based on the estimated fair-value at the grant date and charged to earnings over the vesting period. The Company grants stock options to certain employees and directors. Each tranche is considered a separate award with its own vesting period and grant date fair value. The fair value of each tranche is measured at the date of grant using the Black-Scholes option pricing model. Compensation expense is recognized over the tranche’s vesting period by a charge to earnings, with a corresponding increase to contributed surplus based on the number of awards expected to vest. The number of awards expected to vest is reviewed at least annually, with any impact being recognized immediately.
Current and deferred income taxes | Current and deferred income taxes Income tax comprises current and deferred tax. Income tax is recognized in the statement of operations except to the extent that it relates to items recognized directly in equity, in which case the income tax is also recognized directly in equity. Taxes on income in interim periods are recorded using the tax rate that would be applicable to expected annual profit. Current tax is the expected tax payable on taxable income for the year, using tax rates enacted or substantively enacted, at the end of the reporting period. Deferred tax is recognized in respect of temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the financial statements. Deferred income tax is determined on a non-discounted basis using tax rates and laws that have been enacted or substantively enacted at the balance sheet date and are expected to apply when the deferred tax asset or liability is reversed. Deferred tax assets are recognized to the extent that it is probable that the assets can be recovered. Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associates, except, in the case of subsidiaries, where the timing of the reversal of the temporary difference is controlled by the Company and it is probable that the temporary difference will not reverse in the foreseeable future. As an exception, deferred tax assets and liabilities are not recognized if the temporary differences arise from the initial recognition of goodwill or an asset or liability in a transaction (other than in a business combination) that affects neither accounting profit nor taxable profit. Deferred income tax assets and liabilities are presented as non-current.
Revenue | Revenue Gold revenue is recognized when it is probable that the economic benefits will flow to the Company, delivery has occurred, the sales price is reasonably determinable, and collectability is reasonably assured. These criteria are generally met at the time the product is delivered to the customer and, depending on the delivery conditions, title and the risks and rewards of ownership have passed to the customer and acceptance of the product, when contractually required, has been obtained. Gold revenue is measured based on the price specified in the sales contract at the time of sale. Silver revenue is accounted for as a by-product and is recorded as a credit to operating costs.
Earnings per share | Earnings per share Basic earnings per share is calculated by dividing the net income (loss) for the year attributable to shareholders of the Company by the weighted average number of common shares outstanding during the year. Diluted earnings per share is calculated using the treasury share method whereby all “in-the-money” options, warrants and equivalents are assumed to have been exercised at the beginning of the year and the proceeds from the exercise are assumed to have been used to purchase common shares at the average market price during the period. Diluted earnings per share excludes all dilutive potential common shares if their effect is anti-dilutive.
Ore reserve and resource estimates | Ore reserve and resource estimates Ore 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 ore reserves and mineral resources based on information compiled by appropriately qualified persons relating to the geological data on the size, depth and shape of the ore body, and requires complex geological judgments to interpret the data. The estimation of recoverable reserves is based upon factors such as estimates of foreign exchange rates, commodity prices, future capital requirements, metallurgical recoveries, permitting and production costs along with geological assumptions and judgments made in estimating the size, and grade of the ore body. Changes in the reserve or resource estimates may impact the carrying value of mining interests, mine restoration provisions, recognition of deferred tax assets, depreciation and amortization charges and royalties receivable.
Value-added tax receivables | Value-added tax receivables The Company incurs indirect taxes, including value-added tax, on purchases of goods and services at its operating mines and development projects. Indirect tax balances are recorded at their estimated recoverable amounts within current or long-term assets, net of provisions, and reflect the Company’s best estimate of their recoverability under existing tax rules in the respective jurisdictions in which they arise. Management’s assessment of recoverability considers the probable outcomes of claimed deductions and/or disputes. The provisions and balance sheet classifications made to date may be subject to change and such change may be material.
Deferred income taxes and valuation allowances | Deferred income taxes and valuation allowances The Company is periodically required to estimate the tax basis of assets and liabilities. Where applicable tax laws and regulations are either unclear or subject to varying interpretations, it is possible that changes in these estimates could occur that materially affect the amounts of deferred income tax assets and liabilities recorded in the financial statements. Changes in deferred tax assets and liabilities generally have a direct impact on earnings in the period that the changes occur. Each period, the Company evaluates the likelihood of whether some portion or all of each deferred tax asset will not be realized. This evaluation is based on historic and future expected levels of taxable income, the pattern and timing of reversals of taxable temporary timing differences that give rise to deferred tax liabilities, and tax planning initiatives. Levels of future taxable income are affected by, among other things, market gold prices, production costs, quantities of proven and probable gold reserves, interest rates and foreign currency exchange rates.
Impairment of long-lived assets | Impairment of long-lived assets Long-lived assets are tested for impairment, or reversal of a previous impairment, if there is an indicator of impairment or a subsequent reversal. Calculating the estimated recoverable amount of cash-generating units for long-lived asset requires management to make estimates and assumptions including future production levels, mill recoveries, operating and capital costs in its life-of-mine plans, future metal prices, foreign exchange rates, taxation rates, and discount rates. Changes in any of the assumptions or estimates used in determining the recoverable amount could impact the analysis. Such changes could be material.
Exploration and evaluation expenditures | Exploration and evaluation expenditures The application of the Company’s accounting policy for exploration and evaluation expenditures requires judgment in determining whether it is likely that future economic benefits are likely either from future exploitation or sale or where activities have not reached a stage which permits a reasonable assessment of the existence of reserves. The deferral policy requires management to make certain estimates and assumptions about future events or circumstances, in particular whether an economically viable mine can be established. Estimates and assumptions made may change if new information becomes available. If, after an expenditure is capitalized, information becomes available suggesting that the recovery of expenditure is unlikely, the amount capitalized is written off in the statement of operations in the period when the new information becomes available.
