Significant Accounting Policies [Abstract] | |
SUMMARY OF ACCOUNTING POLICIES | 3. SUMMARY OF ACCOUNTING POLICIES Cash and cash equivalents Cash includes cash deposits in any currency residing in chequing and sweep accounts. Cash equivalents consist of money market funds and other highly liquid investments purchased with maturities of three months or less. Investments with maturities greater than three months and up to one year are classified as short-term investments, while those with maturities in excess of one year are classified as long-term investments. Cash equivalents and short-term investments are stated at amortized cost, which typically approximates market value. Inventories Inventory classifications include "stockpiled ore," "in-process inventory," "finished goods inventory" and "materials and supplies". The stated value of all production inventories include direct production costs and attributable overhead and depreciation incurred to bring the materials to their current point in the processing cycle. General and administrative costs for corporate offices are not included in any inventories. Stockpiled ore represents coarse ore that has been extracted from the mine and is stored for future processing. Stockpiled ore is measured by estimating the number of tonnes (via truck counts or by physical surveys) added to, or removed from the stockpile, the number of contained ounces (based on assay data) and estimated gold recovery percentage. Stockpiled ore value is based on the costs incurred (including depreciation and amortization) in bringing the ore to the stockpile. Costs are added to the stockpiled ore based on current mining costs per tonne and are removed at the average cost per tonne of ore in the stockpile. In-process inventory represents material that is currently being treated in the processing plants to extract the contained gold and to transform it into a saleable product. The amount of gold in the in-process inventory is determined by assay and by measure of the quantities of the various gold-bearing materials in the recovery process. The in-process gold is valued at the average of the beginning inventory and the cost of material fed into the processing stream plus in-process conversion costs including applicable mine-site overheads, depreciation and amortization related to the processing facilities. Finished goods inventory is saleable gold in the form of doré bars. Included in the costs are the direct costs of the mining and processing operations as well as direct mine-site overheads, amortization and depreciation. Materials and supplies inventories consist mostly of equipment parts and other consumables required in the mining and ore processing activities. All inventories are valued at the lower of average cost or net realizable value. Property, plant and equipment Property, plant and equipment assets, including machinery, processing equipment, mining equipment, mine site facilities, buildings, vehicles and expenditures that extend the life of such assets, are initially recorded at cost including acquisition and installation costs. Property, plant and equipment are subsequently measured at cost, less accumulated depreciation and accumulated impairment losses. The costs of self-constructed assets include direct construction costs and direct overhead during the construction phase. Indirect overhead costs are not included in the cost of self-constructed assets. Depreciation for mobile equipment and other assets having estimated lives shorter than the estimated life of the ore reserves is calculated using the straight-line method at rates which depreciate the cost of the assets, less their anticipated residual values, if any, over their estimated useful lives. Mobile mining equipment is amortized over a five year life. Assets, such as processing plants, power generators and buildings, which have an estimated life equal to or greater than the estimated life of the ore reserves, are amortized over the life of the proven and probable reserves of the associated mining property using a units-of-production amortization method, less their anticipated residual values, if any. The net book value of property, plant and equipment assets is charged against income if the mine site is abandoned and it is determined that the assets cannot be economically transferred to another project or sold. The residual values, useful lives and method of depreciation of property, plant and equipment are reviewed at each reporting period end, and adjusted prospectively if appropriate. Gains and losses on the disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount, and are recognized net in the consolidated statement of operations. Mining properties Mining property assets, including property acquisition costs, tailings storage facilities, mine-site development and drilling costs where proven and probable reserves have previously been established, pre-production waste stripping, condemnation drilling, roads, feasibility studies and wells are recorded at cost. The costs of self-constructed assets include direct construction costs, direct overhead costs and allocated interest during the construction phase. Indirect overhead costs are not included in the cost of self-constructed assets. Mining property assets are amortized over the life of the proven and probable reserves to which they relate, using a units-of-production amortization method. At open pit mines the costs of removing overburden from an ore body in order to expose ore during its initial development period are capitalized. Underground mine development costs Underground mine development costs include development costs to build new shafts, drifts and ramps that will enable the Company to physically access ore underground. The time over which the Company will continue to incur these costs depends on the mine life. These underground development costs are capitalized as incurred. Capitalized underground development costs incurred to enable access to specific ore blocks or areas of the underground mine, and which only provide an economic benefit over the period of mining that ore block or area, are depreciated on a units-of-production basis, whereby the denominator is estimated ounces of gold in proven and probable reserves and the portion of resources within that ore block or area that is considered probable of economic extraction. If capitalized underground development costs provide an economic benefit over the entire mine life, the costs are depreciated on a units-of-production basis, whereby the denominator is the estimated ounces of gold in total accessible proven and probable reserves and the portion of resources that is considered probable of economic extraction. Borrowing costs Borrowing costs attributable to the acquisition, construction or production of a qualifying asset are capitalized. Qualifying assets are assets that require a significant amount of time to prepare for their intended use, including projects that are in the exploration and evaluation, development or construction stages. Capitalized borrowing costs are considered an element of the cost of the qualifying asset which is determined based on gross expenditures incurred on an asset. Capitalization ceases when the asset is substantially complete or if active development is suspended or ceases. Where the funds used to finance a qualifying asset form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to the relevant borrowings during the period. Where funds borrowed are directly attributable to a qualifying asset, the amount capitalized represents the borrowing costs specific to those borrowings. Other borrowing costs are recognized as an expense in the period in which they are incurred. Impairment of long-lived assets The Company assesses at each reporting period whether there is an indication that an asset or group of assets may be impaired. When impairment indicators exist, the Company estimates the recoverable amount of the asset and compares it against the asset's carrying amount. The recoverable amount is the higher of its fair value less cost of disposal ("FVLCD") and the asset's value in use ("VIU"). If the carrying amount exceeds the recoverable amount, an impairment loss is recorded in the consolidated statement of operations. In assessing VIU, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset not already reflected in the estimates of future cash flows. The cash flows are based on best estimates of expected future cash flows from the continued use of the asset and its eventual disposal. FVLCD is best evidenced if obtained from an active market or binding sale agreement. Where neither exists, the fair value is based on the best estimates available to reflect the amount that could be received from an arm's length transaction. Future cash flows are based on estimated quantities of gold and other recoverable metals, expected price of gold (considering current and historical prices, price trends and related factors), production levels and cash costs of production, capital and reclamation costs, all based on detailed engineered life-of-mine plans. Numerous factors including, but not limited to, unexpected grade changes, gold recovery variances, shortages of equipment and consumables, and equipment failures could impact our ability to achieve forecasted production schedules from proven and probable reserves. Additionally, commodity prices, capital expenditure requirements and reclamation costs could differ from the assumptions used in the cash flow models used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral interests involves further risks in addition to those factors applicable to mineral interests where proven and probable reserves have been identified, due to the lower level of confidence that the identified mineralized material can ultimately be mined economically. If an impairment loss reverses in a subsequent period, the carrying amount (post reversal) of the related asset is increased to the revised estimate of recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset previously. Reversals of impairment losses are recognized in the statement of operations in the period the reversals occur. Material changes to any of the factors or assumptions discussed above could result in future asset impairments. Rehabilitation provisions The Company records a liability and corresponding asset for the present value of the estimated costs of legal and constructive obligations for future site reclamation and closure where the liability is probable and a reasonable estimate can be made of the obligation. The estimated present value of the obligation is reassessed on a periodic basis or when new material information becomes available. Increases or decreases to the obligation usually arise due to changes in legal or regulatory requirements, the extent of environmental remediation required, methods of reclamation, cost estimates, inflation rates, or discount rates. Changes to the provision for reclamation and remediation obligations related to operating mines, which are not the result of current production of inventory, are recorded with an offsetting change to the related asset. Changes to the provision for reclamation and remediation obligations related to suspended mine operations are recognized in the consolidated statements of operations and comprehensive loss. The present value is determined based on current market assessments of the time value of money using discount rates based on the risk-free rate maturing approximating the timing of expected expenditures to be incurred, and adjusted for country related risks. The periodic unwinding of the discount is recognized in the consolidated statement of operations as a finance expense. Deferred revenue From January 1, 2018, deferred revenue consists of: 1) initial cash payments received by the Company for future delivery of payable gold under the terms of the Company’s Streaming Agreement as defined in Note 11 , Deferred Revenue, and 2) a significant financing component of the Company’s Streaming Agreement. Deferred revenue is increased as interest expense is recognized based on the implicit interest rate of the discounted cash flows arising from the expected delivery of ounces under the Company’s Streaming Agreement. The amount by which the deferred revenue balance is reduced and recognized into revenue is based on a rate per ounce of gold delivered under the stream. This rate per ounce of gold delivered relating to the payments received by the Company is based on the remaining deferred revenue balance divided by the ounces that are expected to be delivered over the term of the Stream Agreement. As the Company’s Streaming Agreement contains a variable component, IFRS 15 requires that the transaction price be updated and re-allocated on an ongoing basis. As a result, the deferred revenue recognized per ounce of gold delivered under the Streaming Agreement will require an adjustment each time there is a significant change in the underlying gold production profile of a mine. Should a change in the transaction price be necessary, a cumulative catch-up adjustment to revenue will be made in the period in which the change occurs, to reflect the updated production profile expected to be delivered under the Streaming Agreement. Foreign currency transactions The Company's presentation currency of its consolidated financial statements is the U.S. dollar, as is the functional currency of its operations. The functional currency of all consolidated subsidiaries is the U.S. dollar. All values are rounded to the nearest thousand, unless otherwise stated. Monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at period end exchange rates. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are translated into U.S. dollars at the exchange rate at the date that the fair value was determined. Income and expense items are translated at the exchange rate in effect on the date of the transaction. Exchange gains and losses resulting from the translation of these amounts are included in net loss, except those arising on the translation of equity investments at fair value through other comprehensive income that are recorded in other comprehensive income. Non-monetary assets and liabilities denominated in foreign currencies that are measured at historical cost are translated at the exchange rate in effect at the transaction date . Income taxes Income taxes comprise the provision for (or recovery of) taxes actually paid or payable (current taxes) and for deferred taxes. Current taxes are based on taxable earnings in the year. Current tax is calculated using tax rates and laws that were enacted or substantively enacted at the balance sheet date in the respective jurisdictions. Current income tax assets and current income tax liabilities are only offset if a legally enforceable right exists to offset the amounts and the Company intends to settle on a net basis or to realize the asset and settle the liability simultaneously. Deferred income tax assets and liabilities are recognized for the expected future tax consequences attributable to temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. Deferred income tax assets and liabilities are computed using enacted or substantially enacted income tax rates in effect when the temporary differences are expected to reverse. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in the period of substantial enactment. The provision for or the recovery of deferred taxes is based on the changes in deferred tax assets and liabilities during the period. The carrying amount of deferred income tax assets or liabilities are reviewed at the end of each reporting period and recognized to the extent that it is probable that taxable earnings will be available against which deductible temporary differences can be utilized. Net income/(loss) per share Basic income/(loss) per share of common stock is calculated by dividing income available to Golden Star's common shareholders by the weighted average number of common shares issued and outstanding during the period. In periods with earnings, the calculation of diluted net income per common share uses the treasury stock method to compute the dilutive effects of stock options, convertible debentures and other potentially dilutive instruments. In periods of loss, diluted net loss per share is equal to basic loss per share. Revenue recognition Revenue from the sale of metal is recognized when the Company transfers control over to a customer. All of our spot sales of gold are transported to a South African gold refiner who locates a buyer and arranges for sale of our gold on the same day that the gold is shipped from the mine site. The sales price is based on the London P.M. fix on the day of shipment. Revenue recognition for the Company’s Streaming Agreement is disclosed in the accounting policy for deferred revenue. Share-based compensation Under the Company's Fourth Amended and Restated 1997 Stock Option Plan, common share options may be granted to executives, employees, consultants and non-employee directors. Compensation expense for such grants is recorded in the consolidated statements of operations and comprehensive loss, with a corresponding increase recorded in the contributed surplus account in the consolidated balance sheet. The expense is based on the fair value of the option at the time of grant, measured by reference to the fair value determined using a Black-Scholes valuation model, and is recognized over the vesting periods of the respective options on a graded basis. Consideration paid to the Company on exercise of options is credited to share capital. Under the Company's Deferred Share Unit ("DSU") plan, DSUs may be granted to executive officers and directors. Compensation expense for such grants is recorded in the consolidated statements of operations and comprehensive loss with a corresponding increase recorded in the contributed surplus account in the consolidated balance sheets. The expense is based on the fair values at the time of grant and is recognized over the vesting periods of the respective DSUs. Upon exercise the Company's compensation committee may, at its discretion, issue cash, shares or a combination thereof. Under the Company's Share Appreciation Rights ("SARs") plan allows SARs to be issued to executives, employees and directors. These awards are settled in cash on the exercise date equal to the Company's stock price less the strike price. Since these awards are settled in cash, the Company marks-to-market the associated expense for each award at the end of each reporting period using a Black-Scholes model. The Company accounts for these as liability awards and marks-to-market the fair value of the award until final settlement. Under the Company's Performance Share Units ("PSU") plan, PSUs may be granted to executives, employees and non-employee directors. Each PSU represents one notional common share that is redeemed for cash based on the value of a common share at the end of the three year performance period, to the extent performance and vesting criteria have been met. The PSUs vest at the end of a three year performance. The cash award is determined by multiplying the number of units by the performance adjusting factor, which ranges from 0% to 200% . The performance factor is determined by comparing the Company's share price performance to the share price performance of a peer group of companies as listed in the PSU plan. As the Company was required to settle these awards in cash, they were accounted for as liability awards with corresponding compensation expense recognized. The final PSU grant vested on December 31, 2018 and as a result the Company did not recognize a PSU expense in 2019. Under the Company's 2017 performance and restricted share unit plan (the "2017 PRSU Plan"), performance share units ("2017 PSUs") and restricted share units ("2017 RSUs" and, together with the 2017 PSUs, the "Share Units") may be issued to any employee or officer of the Company or its designated affiliates. Share Units may be redeemed for: (i) common shares issued from treasury; (ii) common shares purchased in the secondary market; (iii) a cash payment; or (iv) a combination of (i), (ii) and (iii). Each PRSU represents one notional common share that is redeemed for common shares or common shares plus cash subject to the consent of the Company based on the value of a common share at the end of the three year performance period, to the extent performance and vesting criteria have been met. The PRSUs vest at the end of a three year performance period. The award is determined by multiplying the number of Share Units by the performance adjustment factor, which ranges from 0% to 200% . The performance adjustment factor is determined by comparing the Company's share price performance to the share price performance of a peer group of companies as listed in the 2017 PRSU Plan. As the Company has a practice of settling these awards in common shares, they are accounted for as equity awards with corresponding compensation expense recognized. Right of Use Asset and Lease Liabilities Until December 31, 2018 leases that transfer substantially all of the benefits and risks of ownership to the Company were recorded as finance leases and classified as property, plant and equipment with a corresponding amount recorded with current and long-term debt. All other leases were classified as operating leases under which leasing costs were expensed in the period incurred. On January 1, 2019, the Company adopted the requirements of IFRS 16 Leases . As a result, the Company updated its accounting policy for leases to align with the requirements of IFRS 16. The Company elected to use the modified retrospective approach to initially adopt IFRS 16 which resulted in recognizing the cumulative effect of prior period amounts as an adjustment to the opening balance sheet through opening deficit on January 1, 2019. From January 1, 2019, the Company recognizes a lease liability and a right-of-use asset at the lease commencement date. The lease liability is initially measured as the present value of future lease payments discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, each operation’s applicable incremental borrowing rate. The incremental borrowing rate is the rate which the operation would have to pay to borrow, over a similar term and with a similar security, the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment. Lease payments included in the measurement of the lease liability comprise the following: fixed payments, including in-substance fixed payments, less any lease incentives receivable, variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date, amounts expected to be payable by the Company under residual value guarantees, the exercise price of a purchase option if the Company is reasonably certain to exercise that option, and payments of penalties for terminating the lease, if the Company expects to exercise an option to terminate the lease. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability, reducing the carrying amount to reflect lease payments made, and remeasuring the carrying amount to reflect any reassessment or lease modifications. The lease liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option. The right-of-use asset is initially measured at cost, which comprises the following: the amount of the initial measurement of the lease liability, any lease payments made at or before the commencement date, less any lease incentives received, any initial direct costs incurred by the Company, and an estimate of costs to be incurred by the Company in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease, unless those costs are incurred to produce inventories. The right-of-use asset is subsequently measured at cost, less any accumulated depreciation and any accumulated impairment losses, and adjusted for any remeasurement of the lease liability. It is depreciated in accordance with the Company’s accounting policy for plant and equipment, from the commencement date to the earlier of the end of its useful life or the end of the lease term. Each lease payment is allocated between the lease liability and finance cost. The finance cost is charged to net earnings over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. On the consolidated balance sheet, right-of-use assets and lease liabilities are reported in mineral properties, plant and equipment and debt and lease liabilities, respectively. Financial instruments The Company recognizes all financial assets initially at fair value and classifies them into one of the following measurement categories: fair value through profit or loss (“FVTPL”), fair value through other comprehensive income (“FVOCI”) or amortized cost, as appropriate. The Company recognizes all financial liabilities initially at fair value and classifies them as either FVTPL or loans and borrowings, as appropriate. The Company has not classified any of its derivatives as hedging instruments in an effective hedge. Derivatives From time to time the Company may utilize foreign exchange and commodity price derivatives to manage exposure to fluctuations in foreign currency exchange rates and gold prices, respectively. The Company does not employ derivative financial instruments for trading purposes or for speculative purposes. Derivative instruments are recorded on the balance sheet at fair value with changes in fair value recorded in the consolidated statement of operations. The Company did not have any foreign exchange derivatives outstanding at December 31, 2019 . 7% Convertible Debentures embedded derivative The Company's 7% Convertible Debentures embedded derivative is considered a financial instrument at FVTPL. The embedded derivative was recorded at fair value on the date of debt issuance. It is subsequently remeasured at fair value at each reporting date, and the changes in the fair value are recorded in the consolidated statement of operations. The fair value of the embedded derivative is determined using a convertible note valuation model, using assumptions based on market conditions existing at the reporting date. Non-hedge derivative contracts During the year ended December 31, 2019 , the Company entered into costless collars consisting of puts and calls, on 50,000 ounces of gold with a floor price of $1,400 per ounce and a ceiling price of $1,750 per ounce with maturity dates ranging from October 2019 to September 2020. The non-hedge accounted collar contracts are considered fair value through profit or loss financial instruments with fair value determined using pricing models that utilize a variety of observable inputs that are a combination of quoted prices, applicable yield curves and credit spreads. The non-hedge derivative contracts are included with prepaids and other or accounts payable and accrued liabilities on the balance sheet. Share capital Common shares are classified as equity. Costs directly attributable to the issue of new shares or share options are shown in equity as a deduction, net of tax, from the gross proceeds. Changes in accounting policies The Company has adopted the following new and revised standards, effective January 1, 2019. These changes were made in accordance with the applicable transitional provisions. IFRS 16 Leases specifies how an IFRS reporter will recognize, measure, present and disclose leases. The standard provides a single lessee accounting model, requiring lessees to recognize assets and liabilities for all leases unless the lease term is 12 months or less or the underlying asset has a low value. Lessors continue to classify leases as operating or finance, with IFRS 16's approach to lessor accounting substantially unchanged from its predecessor, IAS 17. IFRS 16 was issued in January 2016 and applies to annual reporting periods beginning on or after January 1, 2019. On adoption of this standard the Company elected to use the modified retrospective approach to initially adopt IFRS 16 which resulted in recognizing the cumulative effect of prior period amounts as an adjustment to the opening balance sheet through opening deficit on January 1, 2019. Under IFRS 16, the Company recognized lease liabilities in relation to leases which had previously been classified as "operating leases" under the principles of IAS 17 Leases. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as of January 1, 2019. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 7.5% . The associated right-of-use assets for property leases were measured on a retrospective basis as if the new rules had always been applied. The change in accounting policy resulted in an increase to mining interests (plant and equipment) of $0.7 million and an increase to long term debt (finance leases) of $0.5 million . The net impact on retained earnings on January 1, 2019 was a decrease of $0.1 million . IFRIC 23 Uncertainty over income tax treatments clarifies how the recognition and measurement requirements of IAS 12, Income Taxes, are applied where there is uncertainty over income tax treatments effective for years beginning on or after January 1, 2019. There was no accounting impact to the financial statements on adoption of this standard. |

CRITICAL ACCOUNTING JUDGEMENTS, ESTIMATES AND ASSUMPTIONS | 4. CRITICAL ACCOUNTING JUDGEMENTS, ESTIMATES AND ASSUMPTIONS Preparation of our consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that can affect reported amounts of assets, liabilities, revenues and expenses and the accompanying disclosures. Estimates and assumptions are continuously evaluated and are based on management's historical experience and on other assumptions we believe to be reasonable under the circumstances. However, uncertainty about these judgments, estimates and assumptions could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods. Mineral reserves and resources Determining mineral reserves and resources is a complex process involving numerous variables and is based on a professional evaluation using accepted international standards for the assessment of mineral reserves. Estimation is a subjective process, and the accuracy of such estimates is a function of the quantity and quality of available data, the assumptions made and judgments used in engineering and geological interpretation. Mineral reserve estimation may vary as a result of changes in the price of gold, production costs, and with additional knowledge of the ore deposits and mining conditions. Differences between management's assumptions including economic assumptions such as metal prices and market conditions could have a material effect in the future on the Company's results and financial position, particularly a change in the rate of depreciation and amortization of the related mining assets and the recognition of deferred revenue. Units of production depreciation The mineral properties and a large portion of the property, plant and equipment is depreciated/amortized using the units of production method over the expected operating life of the mine based on estimated recoverable ounces of gold, which are the prime determinants of the life of a mine. Estimated recoverable ounces of gold include proven and probable mineral reserves. Changes in the estimated mineral reserves will result in changes to the depreciation charges over the remaining life of the operation. A decrease in the mineral reserves would increase depreciation and amortization expense and this could have a material impact on the operating results. The amortization base is updated on an annual basis based on the new mineral reserve and resource estimates. Carrying value of assets and impairment charges The Company undertakes a review of its assets at each reporting period to determine whether any indication of impairment exists. Where an indicator of impairment exists, a formal estimate of the recoverable amount of the asset or cash-generating unit ("CGU") is made, which is considered to be the higher of its FVLCD and VIU. An impairment loss is recognized when the carrying value of the asset or CGU is higher than the recoverable amount. In undertaking this review, management of the Company is required to make significant estimates of, amongst other things, discount rates, future production and sale volumes, metal prices, reserves and resource quantities, future operating and capital costs and reclamation costs to the end of the mine's life. These estimates are subject to various risks and uncertainties, which may ultimately have an effect on the expected recoverability of the carrying values of the asset or CGU. In determining a CGU, management has examined the smallest identifiable group of assets that generates cash inflows that are largely independent of cash inflows from other assets or group of assets. Assessment of impairment and reverse impairment indicators Management applies significant judgment in assessing whether indicators of impairment or reverse impairment exist for an asset or group of assets which would necessitate impairment testing. Internal and external factors such as significant changes in the use of the asset, commodity prices and production costs are used by Management in determining whether there are any indicators. Rehabilitation provisions Environmental reclamation and closure liabilities are recognized at the time of environmental disturbance, in amounts equal to the discounted value of expected future reclamation and closure costs. The estimated future cash costs of such liabilities are based primarily upon environmental and regulatory requirements of the various jurisdictions in which we operate as well as any other constructive obligations that exist. The liability represents management's best estimates of cash required to settle the liability, inflation, assumptions of risks associated with future cash flows and the applicable risk-free interest rates for discounting the future cash outflow. The liability is reassessed and remeasured at each reporting date. Fair value of financial instruments, including embedded derivatives Where the fair value of financial assets and financial liabilities recorded in the financial statements cannot be derived from active markets, their fair value is determined using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgment is required in establishing fair values. The judgments include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments. When measuring the fair value of an asset or liability, the Company uses observable market data to the greatest extent possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows: Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices) Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs) Income taxes We deal with uncertainties and judgments in the application of complex tax regulations in the various jurisdictions where our properties are located. The amount of taxes paid is dependent upon many factors, including negotiations with taxing authorities in the various jurisdictions and resolution of disputes arising from our international tax audits. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues in our various tax jurisdictions based on our best estimate of additional taxes payable. We adjust these tax estimates in light of changing facts and circumstances, however, due to the complexity of some of these uncertainties, the ultimate resolution may result in payment that is materially different from our estimates of our tax liabilities. If our estimate of tax liability proves to be less than the ultimate assessment, an additional charge to expense would result. If the estimate of tax liabilities proves to be greater that the ultimate assessment, a tax benefit is recognized. A deferred tax asset is recognized to the extent that it is probable that taxable earnings will be available against which deductible temporary differences can be utilized. Deferred revenue Significant judgment is required in determining the appropriate accounting for the Streaming Agreement that has been entered into. Management has determined that based on the agreements reached that it assumes significant business risk associated with the timing and amount of ounces of gold being delivered. As such, the deposits received have been recorded as deferred revenue liabilities in the consolidated balance sheet. The amount by which the deferred revenue balance is reduced and recognized into revenue is based on a rate per ounce of gold delivered under the stream. This rate per ounce of gold delivered relating to the payments received by the Company is based on the remaining deferred revenue balance divided by the ounces that are expected to be delivered over the term of the Stream Agreement. As the Company’s Streaming Agreement contains a variable component, IFRS 15 requires that the transaction price be updated and re-allocated on an ongoing basis. As a result, the deferred revenue recognized per ounce of gold delivered under the Streaming Agreement will require an adjustment each time there is a significant change in the underlying gold production profile of a mine. Should a change in the transaction price be necessary, a retroactive adjustment to revenue will be made in the period in which the change occurs, to reflect the updated production profile expected to be delivered under the Streaming Agreement. |

FINANCIAL INSTRUMENTS | 5. FINANCIAL INSTRUMENTS The following tables illustrate the classification of the Company's recurring fair value measurements for financial instruments within the fair value hierarchy and their carrying values and fair values as at December 31, 2019 and December 31, 2018 : December 31, 2019 December 31, 2018 Level Carrying value Fair value Carrying value Fair value Financial Liabilities Fair value through profit or loss 7% Convertible Debentures embedded derivative 3 5,608 5,608 4,177 4,177 Non-hedge derivative contracts 2 211 211 — — There were no non-recurring fair value measurements of financial instruments as at December 31, 2019 . The three levels of the fair value hierarchy are: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 - Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and Level 3 - Inputs that are not based on observable market data. The Company's policy is to recognize transfers into and transfers out of the fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. During the year ended December 31, 2019 , there were no transfers between the levels of the fair value hierarchy. Loss/(gain) on fair value of financial instruments in the Statements of Operations and Comprehensive Loss consists of the following: For the Years Ended 2019 2018 Loss/(gain) on fair value of 7% Convertible Debentures embedded derivative $ 1,431 $ (6,786 ) Unrealized loss on non-hedge derivative contracts 211 — $ 1,642 $ (6,786 ) The valuation technique that is used to measure fair value is as follows: 7% Convertible Debentures embedded derivative The debt component of the 7% Convertible Debentures is recorded at amortized cost using the effective interest rate method, and the conversion feature is classified as an embedded derivative measured at fair value through profit or loss. The embedded derivative was valued at December 31, 2019 and December 31, 2018 using a convertible note valuation model. The significant inputs used in the convertible note valuation are as follows: December 31, 2019 December 31, 2018 Embedded derivative Risk premium 5.3 % 5.0 % Borrowing costs 7.5 % 10.0 % Expected volatility 45.0 % 45.0 % Remaining life (years) 1.6 2.6 The following table presents the changes in the 7% Convertible Debentures embedded derivative for the year ended December 31, 2019 : Fair value Balance at December 31, 2018 $ 4,177 Loss on fair value of 7% Convertible Debentures embedded derivative 1,431 Balance at December 31, 2019 $ 5,608 If the risk premium increases by 10% , the fair value of the 7% Convertible Debentures embedded derivative would decrease and the related loss in the Statement of Operations would decrease by $0.1 million at December 31, 2019 . If the borrowing costs increases by 10% , the fair value of the 7% Convertible Debentures embedded derivative would decrease and the related loss in the Statement of Operations would decrease by $0.1 million at December 31, 2019 . If the expected volatility increases by 10% , the fair value of the 7% Convertible Debentures embedded derivative would increase and the related loss in the Statement of Operations would increase by $0.7 million at December 31, 2019 . Non-hedge derivative contracts During the year ended December 31, 2019 , the Company entered into costless collars consisting of puts and calls, on 50,000 ounces of gold with a floor price of $1,400 per ounce and a ceiling price of $1,750 per ounce with maturity dates ranging from October 2019 to September 2020. The non-hedge accounted collar contracts are considered fair value through profit or loss financial instruments with fair value determined using pricing models that utilize a variety of observable inputs that are a combination of quoted prices, applicable yield curves and credit spreads. The non-hedge derivative contracts are included with accounts payable and accrued liabilities on the balance sheet. During the year ended December 31, 2019 , the Company recognized an unrealized loss of $0.2 million on the non-hedge accounted collar contracts. |

Incomes Taxes [Abstract] | |
INCOME TAXES | 8. INCOME TAXES We recognize deferred tax assets and liabilities based on the difference between the financial reporting and tax basis of assets and liabilities using the tax rates enacted or substantively enacted when the temporary differences are expected to reverse. Deferred tax assets are fully recognized when we conclude sufficient positive evidence exists to demonstrate that it is probable that a deferred tax asset will be realized. These factors included, but are not limited to, (a) historic and expected future levels of taxable income; (b) tax plans that affect whether tax assets can be realized; and (c) the nature, amount and expected timing of reversal of taxable temporary differences. Levels of future income are affected by market price of gold, forecasted future costs of production and quantities of proven and probable gold reserves. If these factors or other circumstances changes, the Company records an adjustment to the recognition of deferred tax asset to reflect the Company’s latest assessment of the amount of deferred tax asset that is probable to be realized. Our net deferred tax (liabilities)/assets at December 31, 2019 and 2018 include the following components: December 31, December 31, Deferred tax assets Tax losses carried forward $ — $ 10,322 Deductible temporary differences relating to provisions 4,672 5,995 Deferred tax liabilities Mine property costs 25,226 15,723 Net deferred tax (liabilities)/assets $ (20,554 ) $ 594 The composition of our unrecognized deferred tax assets by tax jurisdiction is summarized as follows: December 31, December 31, Deductible temporary differences Canada $ 7,006 $ 8,844 Ghana 49,869 31,509 $ 56,875 $ 40,353 Tax losses Canada $ 60,195 $ 50,718 U.S. 138 175 Ghana 305,261 287,545 $ 365,594 $ 338,438 Total unrecognized deferred tax assets Canada $ 67,201 $ 59,562 U.S. 138 175 Ghana 355,130 319,054 $ 422,469 $ 378,791 The income tax expense includes the following components: For the years ended December 31, 2019 2018 Current tax expense Current tax on net earnings $ 6,291 $ — Deferred tax expense Originating and reversal of temporary differences in the current year 21,148 12,350 Income tax expense $ 27,439 $ 12,350 A reconciliation of expected income tax on net loss before minority interest at statutory rates with the actual income tax expense is as follows: For the years ended December 31, 2019 2018 Net loss before tax $ (50,534 ) $ (11,721 ) Statutory tax rate 26.5 % 26.5 % Tax benefit at statutory rate $ (13,392 ) $ (3,106 ) Foreign tax rates (21,367 ) (15,562 ) Other — 132 Non taxable/deductible items 1,914 (676 ) Change in unrecognized deferred tax assets due to exchange rates (2,424 ) 3,427 Change in unrecognized deferred tax assets due to impairment 19,867 — Change in unrecognized deferred tax assets 42,841 28,135 Deferred income tax expense $ 27,439 $ 12,350 At December 31, 2019 , the Company had a tax pool and loss carryovers expiring as follows: Canada Ghana Other 2020 $ — $ 63,099 $ — 2021 — 12,822 — 2022 — — — 2023 — 80,486 — 2024 — 130,324 — 2026 8,519 — — 2027 12,918 — — 2028 11,659 — — 2029 17,679 — — 2030 15,802 — — 2031 29,646 — — 2032 14,351 — — 2033 6,177 — 174 2034 — — 364 2035 8,450 — 1 2036 13,777 — 120 2037 15,565 — — 2038 27,439 — — 2039 24,997 — — Indefinite 40,347 585,443 — Total $ 247,326 $ 872,174 $ 659 The total of $872.2 million of the Ghana tax pool is usable against taxable income generated at Prestea. The Ghana Revenue Authority (“GRA”) has issued a tax assessment to the company’s subsidiary (Golden Star (Wassa) Limited) related to 2014-2016. The assessment claimed a reduction in the tax losses attributable by $29 million . The company believes that the majority of the matters noted in the assessment are incorrect and has filed an appeal in an attempt to resolve these matters. Overall, it is the company’s current assessment that the relevant assessments and claims by the GRA are without merit. No amounts have been recorded for any potential liability and the company intends to defend any follow up in relation to this matter should it arise. The amount of loss, if any, cannot be determined at the current time. |

At December 31, 2019 , the rehabilitation provision for Wassa was $17.8 million ( 2018 - $17.2 million ). The Company expects the payments for reclamation to be incurred between 2020 and 2027. During the year ended December 31, 2019 , the Company recorded an increase in estimate for Prestea of $3.1 million . The increase is due to a $3.3 million increase in the expected reclamation costs relating to the non-refractory operation, slightly offset by a $0.2 million reduction in expected reclamation costs relating to the refractory liability. The $0.2 million (2018 - $3.1 million ) reduction in refractory obligation was recorded as other expense/(income) since the carrying value of the underlying refractory assets were $nil after suspension of its operation in 2015. At December 31, 2019 , the rehabilitation provision for Prestea was $50.6 million ( 2018 - $49.0 million ). The Company expects the payments for reclamation to be incurred between 2020 and 2029. |

Disclosure Of Deferred Revenue [Abstract] | |
DEFERRED REVENUE | 11. DEFERRED REVENUE The Company through its subsidiary Caystar Finance Co. completed a $145 million gold purchase and sale agreement (“Streaming Agreement”) with RGLD Gold AG ("RGLD"), a wholly-owned subsidiary of Royal Gold, Inc. Golden Star will deliver 10.5% of gold production from Wassa and Prestea at a cash purchase price of 20% of spot gold until 240,000 ounces have been delivered. Thereafter, 5.5% of gold production will be delivered from Wassa and Prestea at a cash purchase price of 30% of spot gold price. As at December 31, 2019 the Company had delivered a total of 100,181 ounces of gold to RGLD since the inception of the Streaming Agreement. During the year ended December 31, 2019 , the Company sold 21,720 ounces of gold to RGLD. Revenue recognized on the ounces sold to RGLD during the year ended December 31, 2019 consisted of $6.0 million of cash payment proceeds and $13.3 million of deferred revenue recognized in the period (see Note 17 ). For the Years Ended December 31, 2019 2018 Beginning balance $ 119,948 $ 109,956 Impact of adopting IFRS 15 on January 1, 2018 — 18,980 Deferred revenue recognized before cumulative catch-up adjustment (13,334 ) (13,738 ) Variable consideration adjustment 3,073 — Interest on financing component of deferred revenue 4,288 4,750 Balance at the end of the period $ 113,975 $ 119,948 Current portion $ 11,191 $ 14,316 Long term portion 102,784 105,632 Total $ 113,975 $ 119,948 As the Company’s Streaming Agreement contains a variable component, each time there is a significant change in the underlying gold production of the Company’s mines a cumulative catch-up adjustment to revenue is required. In 2019, the Company realized an adjustment to revenue and finance costs due to an increase in the Company’s resource and reserve estimates related primarily to the Wassa mine. The result of the adjustment was to reduce revenue by $(9.3) million , reduce finance expense by $(6.2) million and increase deferred revenue by $3.1 million . |

Additionally, leases liabilities include $1.7 million lease agreements related to the Company's corporate office space which have remaining lease terms of up to 6 years and interest rates of 6.5% - 7.5% over the terms of the lease. Short-term lease payments for the period ended December 31, 2019 were $6.8 million . Ecobank Loan III On February 22, 2017, the Company through its subsidiary Golden Star (Wassa) Limited closed a $25 million secured Medium Term Loan Facility ("Ecobank Loan III") with Ecobank Ghana Limited. Ecobank Loan III had a term of 60 months from the date of initial drawdown and was secured by, among other things, Wassa's existing plant, and certain machinery and equipment having a specified value. The interest rate on the loan was three month LIBOR plus 8% , per annum, payable monthly in arrears beginning a month following the initial drawdown. Repayment of principal commenced six months following the initial drawdown and was thereafter payable quarterly in arrears. The Company had twelve months to drawdown the loan. On January 24, 2018, the Company drew down $15.0 million of the Ecobank Loan III. The full $25.0 million had been drawn as at December 31, 2018. As at December 31, 2019, the Ecobank III Loan had been fully repaid using the proceeds from the Credit Facility. Ecobank Loan IV On June 28, 2018, the Company through its subsidiary Golden Star (Wassa) Limited closed a $20.0 million secured loan facility ("Ecobank Loan IV") with Ecobank Ghana Limited and used the facility to repay in full the $20.0 million Royal Gold loan the Company had outstanding. The loan was secured by, among other things, Wassa's existing plant, and certain machinery and equipment having a specified value. There were no prepayment penalties associated with Ecobank Loan IV and the loan was repayable within 60 months of initial drawdown. Repayment of principal commenced September 2018 and was thereafter payable quarterly in arrears. Interest was payable monthly in arrears at an interest rate equal to three month LIBOR plus a spread of 7.5% per annum. As at December 31, 2019, the Ecobank Loan IV had been fully repaid using the proceeds from the Credit Facility. 7% Convertible Debentures The 7% Convertible Debentures were issued on August 3, 2016, in the amount of $65.0 million due August 15, 2021. The Company entered into exchange and purchase agreements with two holders of its 5% Convertible Debentures due June 1, 2017 to exchange $42.0 million principal amount of the outstanding 5% Convertible Debentures for an equal principal amount of 7% Convertible Debentures (the "Exchange"), with such principal amount being included in the issuance of the $65.0 million total aggregate principal amount of the 7% Convertible Debentures. The Company did not receive any cash proceeds from the Exchange. The 7% Convertible Debentures are governed by the terms of an indenture dated August 3, 2016, by and between the Company and The Bank of New York Mellon, as indenture trustee. The 7% Convertible Debentures are senior unsecured obligations of the Company, bear interest at a rate of 7.0% per annum, payable semi-annually on February 1 and August 1 of each year, beginning on February 1, 2017, and will mature on August 15, 2021, unless earlier repurchased, redeemed or converted. Subject to earlier redemption or purchase, the 7% Convertible Debentures are convertible at any time until the close of business on the third business day immediately preceding August 15, 2021 at the option of the holder, and may be settled, at the Company's election, in cash, common shares of the Company, or a combination of cash and common shares based on an initial conversion rate. The initial conversion rate of the 7% Convertible Debentures, subject to adjustment, is approximately 222 common shares of the Company per $1,000 principal amount of 7% Convertible Debentures being converted, which is equivalent to an initial conversion price of approximately $4.50 per common share. The initial conversion rate is subject to adjustment upon the occurrence of certain events. If the 7% Convertible Debentures are converted before August 1, 2019, the Company will, in addition to the consideration payable with the conversion, be required to make a conversion make-whole payment in cash, common shares of the Company or a combination thereof, at the Company's election, equal to the present value of the remaining scheduled payments of interest that would have been made on the 7% Convertible Debentures converted had such debentures remained outstanding from the conversion date to August 1, 2019, subject to certain restrictions. The present value of the remaining scheduled interest payments will be computed using a discount rate equal to 2.0% . Prior to August 15, 2019, the Company could not redeem the 7% Convertible Debentures except in the event of certain changes in applicable tax law. On or after August 15, 2019, the Company may redeem all or part of the outstanding 7% Convertible Debentures at the redemption price, only if the last reported sales price of the Company's common shares for 20 or more trading days in a period of 30 consecutive trading days ending on the trading day prior to the date the Company provides the notice of redemption to holders exceeds 130% of the conversion price in effect on each such trading day. The redemption price is equal to the sum of (1) 100% of the principal amount of the 7% Convertible Debentures to be redeemed, (2) any accrued and unpaid interest to, but excluding, the redemption date, and (3) a redemption make-whole payment, payable in cash, common shares of the Company or a combination thereof, at the Company's election, equal to the present value of the remaining scheduled payments of interest that would have been made on the 7% Convertible Debentures to be redeemed had such debentures remained outstanding from the redemption date to August 15, 2021 (excluding interest accrued to, but excluding, the redemption date, which is otherwise paid pursuant to the preceding clause (2)). The conversion feature referred to above is an embedded derivative. The Company selected to bifurcate the conversion feature from the host instrument, thereby separating it from the debt component. The debt component is recorded at amortized cost, and the embedded derivative is accounted for at fair value. At August 3, 2016, the date of the debt issuance, the fair value of the embedded derivative was $12.3 million . At December 31, 2019 , the fair value of the embedded derivative was $5.6 million ( December 31, 2018 - $4.2 million ). The revaluation loss of $1.4 million is recorded in the Statement of Operations (year ended December 31, 2018 - revaluation gain of $6.8 million ). There were no conversions of the 7% Convertible Debentures during 2019 , therefore, as at December 31, 2019 , $51.5 million principal amount of 7% Convertible Debentures remains outstanding. The changes in the carrying amount of the 7% Convertible Debentures are as follows: For the Years Ended December 31, 2019 2018 Beginning balance $ 44,612 $ 42,515 Accretion of 7% Convertible Debentures discount 2,390 2,097 Balance at the end of the period $ 47,002 $ 44,612 Vendor Agreement On May 4, 2016, the Company entered into an agreement with Volta River Authority, a significant account creditor to settle $36.5 million of current liabilities. Under this agreement, the Company paid $12.0 million and deferred the payment of the remaining $24.5 million until January 2018, after which the outstanding balance was repaid in equal installments over 24 months commencing on January 31, 2018. Interest of 7.5% accrued and was payable beginning in January 2017 (the "Vendor Agreement"). As at December 31, 2019, the Vendor Agreement had been fully repaid using the proceeds from the Credit Facility.

Commitments And Contingencies [Abstract] | |
COMMITMENTS AND CONTINGENCIES | 14. COMMITMENTS AND CONTINGENCIES Our commitments and contingencies include the following items: Environmental bonding in Ghana The Ghana Environmental Protection Agency ("EPA") requires environmental compliance bonds that provide assurance for environmental remediation at our Bogoso/Prestea and Wassa mining operations. To meet this requirement the Company has environmental bonds totaling $9.6 million and $8.1 million for Wassa and Bogoso/Prestea respectively, with a commercial bank in Ghana. These bonds are guaranteed by Golden Star Resources Ltd. There is also a cross guarantee between Wassa and Bogoso/Prestea. The Company also held cash deposits of $1.1 million and $1.0 million for each operation, which are recorded as restricted cash on the consolidated balance sheets. Government of Ghana's rights to increase its participation Under Act 703, the Government of Ghana has the right to acquire a special share in our Ghanaian subsidiaries at any time for no consideration or such consideration as the Government of Ghana and such subsidiaries might agree, and a pre-emptive right to purchase all gold and other minerals produced by such subsidiaries. A special share carries no voting rights and does not participate in dividends, profits or assets. If the Government of Ghana acquires a special share, it may require the Company to redeem the special share at any time for no consideration or for consideration determined by the Company. To date, the Government of Ghana has not sought to exercise any of these rights at our properties. Royalties Government of Ghana The Government of Ghana receives a royalty equal to 5% of mineral revenues earned by Bogoso/Prestea and Wassa. Asikuma Properties As part of the acquisition of the Asikuma properties in 2003, the Company agreed to pay the seller a net smelter return royalty on future gold production from Mampon mineral property which is located on the Asikuma property. As per the acquisition agreement, there will be no royalty due on the first 200,000 ounces produced from Mampon. The amount of the royalty is based on a sliding scale which ranges from 2% of net smelter return at gold prices at or below $300 per ounce and progressively increases to 3.5% for gold prices in excess of $400 per ounce. Since the ounces mined at Mampon were below the 200,000 ounces threshold, we are not required to pay a royalty on this property. Mansiso Properties Bogoso Gold Limited agreed to grant, transfer and convey to Birim Goldfields (Ghana) Limited a net smelter return royalty of 3.5% for any average gold price above $400 per ounce in respect of all mineral products that may be produced from the land pertaining to the Ghanaian Mansiso mineral property. During the year ended December 31, 2019, the Company accrued $0.7 million (year ended December 31, 2018 - $ nil ) in royalty payments related to the Mansiso mineral property. Legal proceedings The Company is involved in legal proceedings, from time to time, arising in the ordinary course of its business. It is not expected that any material liability will arise from current legal proceedings or have a material adverse effect on the Company’s future business, operations or financial condition. |

SHARE-BASED COMPENSATION | 15. SHARE-BASED COMPENSATION Share-based compensation expenses recognized in general and administrative expense in the Statements of Operations and Comprehensive Loss, are as follows: For the Years Ended December 31, 2019 2018 Share options $ 1,890 $ 1,248 Deferred share units 689 565 Share appreciation rights (52 ) (502 ) Performance share units 592 (33 ) $ 3,119 $ 1,278 Share options On May 5, 2016, the Fourth Amended and Restated 1997 Stock Option Plan (the "Stock Option Plan") was approved by shareholders to (i) reserve an additional 2,000,000 common shares for the Stock Option Plan, thereby increasing the total number of common shares issuable from 5,000,000 common shares to 7,000,000 common shares under the Stock Option Plan; (ii) provide for the grant of "incentive stock options" (being stock options designated as "incentive stock options" in an option agreement and that are granted in accordance with the requirements of, and that conforms to the applicable provisions of, Section 422 of the Internal Revenue Code); and (iii) to make such other changes to update the provisions of the Stock Option Plan in light of current best practices. Options granted are non-assignable and are exercisable for a period of ten years or such other period as is stipulated in a stock option agreement between Golden Star and the optionee. Under the Plan, we may grant options to employees, consultants and directors of the Company or its subsidiaries of up to 7,000,000 shares, of which 1,202,583 are available for grant as of December 31, 2019 ( December 31, 2018 - 1,917,767 ). The exercise price of each option is not less than the closing price of our shares on the Toronto Stock Exchange on the day prior to the date of grant. Options typically vest over periods ranging from immediately to four years from the date of grant. Vesting periods are determined at the discretion of the Compensation Committee. The fair value of option grants is estimated at the grant dates using the Black-Scholes option-pricing model. Fair values of options granted during the years ended December 31, 2019 and 2018 were based on the weighted average assumptions noted in the following table: For the Years Ended December 31, 2019 2018 Expected volatility 51.20% 70.06% Risk-free interest rate 1.73% 2.39% Expected lives 5.74 years 5.68 years The weighted average fair value per option granted during the year ended December 31, 2019 was $2.54 CAD ( year ended December 31, 2018 - $2.82 CAD). As at December 31, 2019 , there was $0.5 million of share-based compensation expense ( December 31, 2018 - $0.6 million ) relating to the Company's share options to be recorded in future periods. For the year ended December 31, 2019 , the Company recognized an expense of $1.9 million ( year ended December 31, 2018 - $1.2 million ).

Pursuant to the DSU Plan, directors may elect to receive all or part of their retainer in DSUs having a market value equal to the portion of the retainer to be received in that form, subject to such limits as the Compensation Committee may impose. The Compensation Committee may also grant to any director or executive officer, in each year, DSUs having a market value not greater than the total compensation payable to such director or executive officer for that year, including any salary or bonus but excluding any director’s retainer. The number of DSUs to be issued is determined by dividing the amount of the retainer or base salary determined as the basis for the award by the volume-weighted average trading price of a Common Share (as reported by the NYSE American) for the 20 trading days immediately preceding the date the DSUs are awarded. The vesting schedule of the DSUs is determined at the discretion of the Compensation Committee, but generally in the case of DSUs granted to directors in lieu of director retainers, the DSUs vest immediately on the award date. DSUs otherwise awarded to directors and officers as part of total compensation payable generally vest one-third on each of the first three anniversaries of the award date. At the election of the Compensation Committee in its sole discretion, each DSU granted after the Restatement Effective Date may be redeemed for: (a) cash payment equal to the market value of one Common Share on the date of redemption (the “Redemption Value”), after deduction of applicable taxes and other source deductions required by applicable laws; (b) such number of common shares purchased by the Company on the public market as having an aggregate market value equal to the Redemption Value; or (c) any combination of the foregoing, so long as the aggregate redemption price has a fair market value equal to the Redemption Value. In addition to the foregoing, the Compensation Committee in its sole discretion, may redeem DSUs granted prior to the Restatement Effective Date for common shares issued by the Company from treasury. For the year ended December 31, 2019 , the DSUs that were granted vested immediately and a compensation expense of $0.7 million was recognized for these grants ( year ended December 31, 2018 - $0.6 million ). As of December 31, 2019 , there was no unrecognized compensation expense related to DSUs granted under the Company's DSU Plan. A summary of DSU activity during the years ended December 31, 2019 and 2018 : For the Years Ended December 31, 2019 2018 Number of DSUs, beginning of period ('000) 1,086 1,018 Granted 188 150 Exercised — (82 ) Number of DSUs, end of period ('000) 1,274 1,086 Share appreciation rights ("SARs") On February 13, 2012, the Company adopted a Share Appreciation Rights ("SARs") Plan. The plan allows SARs to be issued to executives, employees and directors that vest after a period of three years. These awards are settled in cash on the exercise date equal to the Company's stock price less the strike price. Since these awards are settled in cash, the Company marks-to-market the associated expense for each award at the end of each reporting period using a Black-Scholes model. The Company accounts for these as liability awards and marks-to-market the fair value of the award until final settlement. As of December 31, 2019 , there was approximately $0.1 million of total unrecognized compensation cost related to unvested SARs ( December 31, 2018 - $0.3 million ). For the year ended December 31, 2019 , the Company recognized a recovery of $0.1 million related to these cash settled awards ( year ended December 31, 2018 - recovery of $0.5 million ). A summary of the SARs activity during the year ended December 31, 2019 and 2018 : For the Years Ended December 31, 2019 2018 Number of SARs, beginning of period ('000) 674 533 Granted 285 304 Exercised (203 ) (36 ) Forfeited (160 ) (127 ) Expired (3 ) — Number of SARs, end of period ('000) 593 674 Performance share units ("PSUs") On January 1, 2014, the Company adopted a Performance Share Unit ("PSU") Plan. Each PSU represented one notional common share that was redeemed for cash based on the value of a common share at the end of the three -year performance period, to the extent performance and vesting criteria had been met. The PSUs vested at the end of a three -year performance period. The cash award was determined by multiplying the number of units by the performance adjustment factor, which ranged from 0% to 200% . The performance adjustment factor was determined by comparing the Company's share price performance to the share price performance of a peer group of companies as listed in the PSU Plan. As the Company was required to settle these awards in cash, they were accounted for as liability awards with corresponding compensation expense recognized. The final PSU grant vested on December 31, 2018 and, as a result, the Company did not recognize a PSU expense in 2019. For the year ended December 31, 2018 the Company recognized a $0.4 million recovery related to PSU's. The Company paid out the final amount owing of $6.4 million in April 2019 and as at December 31, 2019 there is no longer a PSU liability recognized on the Balance Sheet. A summary of the PSU activity during the year ended December 31, 2019 and 2018 : For the Years Ended December 31, 2019 2018 Number of PSUs, beginning of period ('000) 1,173 2,721 Settled (1,173 ) (1,548 ) Number of PSUs, end of period ('000) — 1,173 2017 Performance and restricted share units ("PRSUs") On May 4, 2017, the Company adopted a 2017 performance and restricted share unit plan (the "2017 PRSU Plan"). Pursuant to the 2017 PRSU Plan, performance share units ("2017 PSUs") and restricted share units ("2017 RSUs" and, together with the 2017 PSUs, the "Share Units") may be issued to any employee or officer of the Company or its designated affiliates. Share Units may be redeemed for: (i) common shares issued from treasury; (ii) common shares purchased in the secondary market; (iii) a cash payment; or (iv) a combination of (i), (ii) and (iii). Under the 2017 PRSU plan, the Company may grant up to a maximum of 2,200,000 common shares. As at December 31, 2019, 1,242,155 share units were available for grant. Each PRSU represents one notional common share that is redeemed for common shares or common shares plus cash subject to the consent of the Company based on the value of a common share at the end of the three year performance period, to the extent performance and vesting criteria have been met. The PRSUs vest at the end of a three year performance period. The award is determined by multiplying the number of Share Units by the performance adjustment factor, which ranges from 0% to 200% . The performance adjustment factor is determined by comparing the Company's share price performance to the share price performance of a peer group of companies as listed in the 2017 PRSU Plan. As the Company has a practice of settling these awards in common shares, they are accounted for as equity awards with corresponding compensation expense recognized. PRSUs are accounted for as equity awards with a corresponding compensation expense recognized. For the year ended December 31, 2019 , the Company recognized $0.6 million expense ( year ended December 31, 2018 - $0.3 million ). A summary of the PRSU activity during the years ended December 31, 2019 and 2018 : For the Years Ended December 31, 2019 2018 Number of PRSUs, beginning of period ('000) 791 339 Granted 561 480 Settled (324 ) — Forfeited (394 ) (28 ) Number of PRSUs, end of period ('000) 634 791 |

Disclosure of impairment of assets [Abstract] | |
IMPAIRMENT CHARGES | 19. IMPAIRMENT CHARGES In the fourth quarter of 2019, the Company completed its annual budgeting process. Management observed a decrease in the Prestea mine’s cash flow reflecting adjustments to key mine planning, cost and working capital assumptions following the conclusion of the independent review of the underground operations at Prestea which resulted in a trigger for an impairment test. The recoverable amount of the Prestea CGU of $ nil was determined based on a discounted cash flow analysis of an indicative life of mine model. This life of mine model is management’s best estimate of the recoverable amount of Prestea’s assets at December 31, 2019. The impairment test concluded that the recoverable amount of the Prestea CGU using a Value In Use model was lower than its carrying value as at December 31, 2019. This resulted in an impairment charge of $56.8 million to the consolidated statement of operations and comprehensive loss and a reduction in the carrying value of Prestea’s assets. Key Assumptions: The key assumptions used in determining the recoverable amount of the Prestea CGU include gold price, discount rate and life of mine. 2019 Test Assumptions Gold Price per oz - short term $1,435 - $1,500 Gold Price per oz - long term $1,400 Discount Rate 7 % Life of Mine (years) 7 Changes in gold price and the discount rate assumptions can have a material impact on the recoverable value of each CGU. A significant change in gold prices will result in a reassessment of our life of mine plans, including the determination of reserves and resources which will impact on the recoverable amount of the CGUs. The Company ran sensitivities at Prestea assuming a -/+ $100/oz price for gold as well as a +/- 1% change in the discount rate using the existing discounted cash flow model. Management concluded that an increase of $100/oz over the life of the mine would reduce the impairment charge to $30.0 million . None of the other changes would have had a material impact on the impairment charge. Gold Price - Management estimated gold prices by considering the average of the most recent market commodity price forecasts from a number of recognized financial analysts. Discount rate - A pre-tax discount rate was based on the Company’s estimated weighted average cost of capital. Life of Mine - The life of mine was estimated using management’s latest information including Prestea’s latest reserves and resources estimates as well as information gathered from the independent operational review. |

Except for the sales to RGLD as part of the Streaming Agreement, the refinery arranges for the sale of gold on the day it is shipped from the mine sites and we receive payment for gold sold two working days after the gold leaves the mine site. The global gold market is competitive with numerous banks and refineries willing to buy gold on short notice. Therefore, we believe that the loss of one of our current customers would not materially delay or disrupt revenue. |

Disclosure of general information about financial statements [Abstract] | |
FINANCIAL RISK MANAGEMENT | 26. FINANCIAL RISK MANAGEMENT Our exposure to market risk includes, but is not limited to, the following risks: changes in interest rates on our debt, changes in foreign currency exchange rates and commodity price fluctuations. Liquidity risk Liquidity risk is the risk that the Company will encounter difficulty in meeting obligations associated with financial liabilities that are settled by delivering cash or another financial asset. We manage the liquidity risk inherent in these financial obligations by preparing monthly financial summaries, quarterly forecasts and annual long-term budgets which forecast cash needs and expected cash availability to meet future obligations. Typically these obligations are met by cash flows from operations and from cash on hand. Scheduling of capital spending and acquisitions of financial resources may also be employed, as needed and as available, to meet the cash demands of our obligations. Our ability to repay or refinance our future obligations depends on a number of factors, some of which may be beyond our control. Factors that influence our ability to meet these obligations include general global economic conditions, credit and capital market conditions, results of operations, mineral reserves and resources and the price of gold. Macquarie Credit Facility Financial Covenants The Macquarie Credit Facility includes covenant clauses requiring the Company to maintain certain key financial ratios. The Company must maintain a Debt Service Coverage Ratio of greater than 1.20 :1, tested quarterly on a rolling four-quarter basis as at the end of each of the fiscal quarters beginning with the fiscal quarter ending June 30, 2020; maintain a ratio of Net Debt to EBITDA of less than 3.00 :1, tested quarterly on a rolling four-quarter basis as at the end of each of the fiscal quarters; demonstrate, on the basis of the consolidated financial statements and annual consolidated corporate budget, that from December 31, 2020 and for each fiscal quarter thereafter, the Convertible Debentures can be repaid in full in cash by the maturity in August 2021 while maintaining (after giving effect to such repayment in cash) a positive cash position (excluding restricted cash) of $25 million ; and ensure that at all times the sum of aggregate indebtedness does not exceed $116.5 million . The following table shows our contractual obligations as at December 31, 2019 : Payment due (in thousands) by period (Stated in thousands of U.S dollars) Less than 1 1 to 3 years 4 to 5 years More than Total Accounts payable and accrued liabilities $ 90,842 $ — $ — $ — $ 90,842 Debt 1 15,000 91,498 5,000 — 111,498 Lease liabilities 987 533 607 254 2,381 Interest on long term debt 7,378 7,321 150 5 14,854 Purchase obligations 17,318 — — — 17,318 Rehabilitation provisions 2 5,826 17,749 25,877 24,316 73,768 Total $ 137,351 $ 117,101 $ 31,634 $ 24,575 $ 310,661 1 Includes the outstanding repayment amounts from the 7% Convertible Debentures maturing on August 15, 2021 and the Macquarie Credit Facility. 2 Rehabilitation provisions indicates the expected undiscounted cash flows for each period. As at December 31, 2019 , the Company has current assets of $107.3 million compared to current liabilities of $123.8 million . As at December 31, 2019 , the Company had a cash balance of $53.4 million . The Company expects to meet its short-term financial needs through its cash on hand and cash flow from operations. Interest rate risk Interest rate risk is the risk that the future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Macquarie Credit Facility is 4.5% plus the applicable USD LIBOR rate. Based on our current $60.0 million outstanding balance , a 100 basis point change in the USD LIBOR rate would result in a nominal change in interest expense. We have not entered into any agreements to hedge against unfavorable changes in interest rates, but may in the future actively manage our exposure to interest rate risk. Foreign currency exchange rate risk Currency risk is risk that the fair value of future cash flows will fluctuate because of changes in foreign currency exchange rates. In addition, the value of cash and cash equivalents and other financial assets and liabilities denominated in foreign currencies can fluctuate with changes in currency exchange rates. Since our revenues are denominated in U.S. dollars and our operating units transact much of their business in U.S. dollars, we are typically not subject to significant impacts from currency fluctuations. However, certain purchases of labor, operating supplies and capital assets are denominated in Ghana cedis, euros, British pounds, Australian dollars, South African rand and Canadian dollars. To accommodate these purchases, we maintain operating cash accounts in non-US dollar currencies and appreciation of these non-US dollar currencies against the U.S. dollar results in a foreign currency gain and a decrease in non-U.S. dollar currencies results in a loss. In the past, we have entered into forward purchase contracts for South African rand, euros and other currencies to hedge expected purchase costs of capital assets. During 2019 and 2018, we had no currency related derivatives. At December 31, 2019 and December 31, 2018 , we held $6.1 million and $1.9 million , respectively, of foreign currency. Commodity price risk Gold is our primary product and, as a result, changes in the price of gold can significantly affect our results of operations and cash flows. Based on our gold production in the year, a $100 per ounce change in gold price would result in approximately a $18.7 million and $17.8 million change in our sales revenues and operating cash flows, respectively. To reduce gold price volatility, we have at various times entered into gold price hedges. During the year ended December 31, 2019 , the Company entered into costless collars consisting of puts and calls, on 50,000 ounces of gold with a floor price of $1,400 per ounce and a ceiling price of $1,750 per ounce with maturity dates ranging from October 2019 to September 2020. During the year ended December 31, 2019 , the Company recognized an unrealized loss of $0.2 million on the non-hedge accounted collar contracts. Credit risk Credit risk is the risk that one party to a financial instrument will cause a financial loss for the other party by failing to discharge an obligation. Our credit risk is primarily associated with liquid financial assets and derivatives. We limit exposure to credit risk on liquid financial assets by holding our cash, cash equivalents, restricted cash and deposits at highly-rated financial institutions. Risks associated with gold trade receivables is considered minimal as we sell gold to a credit-worthy buyer who settles promptly within two days of receipt of gold bullion. |

As of As of December 31, December 31, (Deficiency)/equity $ (32,123 ) $ 42,037 Long-term debt 90,782 73,224 $ 58,659 $ 115,261 Cash and cash equivalents (53,367 ) (96,507 ) $ 5,292 $ 18,754 The Company manages its capital structure and makes adjustments to it in light of changes in economic conditions and the risk characteristics of the underlying assets. In doing so, the Company may issue new shares, restructure or issue new debt and acquire or dispose of assets. In order to facilitate the management of its capital requirements, the Company prepares annual budgets that are updated as necessary depending on various factors, including successful capital deployment and general industry conditions. The Company's treasury policy specifies that cash is to be held in banks with a rating of A or higher by Moody's Investors Service or Standard & Poor's Financial Services LLC. In addition, the Company's investment policy allows investment of surplus funds in permitted investments consisting of US treasury bills, notes and bonds, government sponsored agency debt obligations, corporate debt or municipal securities with credit rating of at least AA. All investments must have a maximum term to maturity of one year. |

Significant Accounting Policies [Abstract] | |
Statement of compliance | Statement of compliance The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards ("IFRS"), as issued by the International Accounting Standards Board ("IASB") and with interpretations of the International Financial Reporting Interpretations Committee ("IFRIC") which the Canadian Accounting Standards Board has approved for incorporation into Part 1 of the CPA Canada Handbook – Accounting. These consolidated financial statements were approved by the Board of Directors of the Company on February 18, 2020 . |
Basis of presentation | Basis of presentation These consolidated financial statements include the accounts of the Company and its subsidiaries, whether owned directly or indirectly. The financial statements of the subsidiaries are prepared for the same period as the Company using consistent accounting policies for all periods presented, except for the changes in accounting policies described in Note 3 below. All inter-company balances and transactions have been eliminated. Subsidiaries are entities controlled by the Company. Non-controlling interests in the net assets of consolidated subsidiaries are a separate component of the Company's equity. These consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and discharge of all liabilities in the normal course of business. The consolidated financial statements have been prepared on a historical cost basis, except for derivative financial instruments which are measured at fair value through profit or loss. |
Cash and cash equivalents | Cash and cash equivalents Cash includes cash deposits in any currency residing in chequing and sweep accounts. Cash equivalents consist of money market funds and other highly liquid investments purchased with maturities of three months or less. Investments with maturities greater than three months and up to one year are classified as short-term investments, while those with maturities in excess of one year are classified as long-term investments. Cash equivalents and short-term investments are stated at amortized cost, which typically approximates market value. |
Inventories | Inventories Inventory classifications include "stockpiled ore," "in-process inventory," "finished goods inventory" and "materials and supplies". The stated value of all production inventories include direct production costs and attributable overhead and depreciation incurred to bring the materials to their current point in the processing cycle. General and administrative costs for corporate offices are not included in any inventories. Stockpiled ore represents coarse ore that has been extracted from the mine and is stored for future processing. Stockpiled ore is measured by estimating the number of tonnes (via truck counts or by physical surveys) added to, or removed from the stockpile, the number of contained ounces (based on assay data) and estimated gold recovery percentage. Stockpiled ore value is based on the costs incurred (including depreciation and amortization) in bringing the ore to the stockpile. Costs are added to the stockpiled ore based on current mining costs per tonne and are removed at the average cost per tonne of ore in the stockpile. In-process inventory represents material that is currently being treated in the processing plants to extract the contained gold and to transform it into a saleable product. The amount of gold in the in-process inventory is determined by assay and by measure of the quantities of the various gold-bearing materials in the recovery process. The in-process gold is valued at the average of the beginning inventory and the cost of material fed into the processing stream plus in-process conversion costs including applicable mine-site overheads, depreciation and amortization related to the processing facilities. Finished goods inventory is saleable gold in the form of doré bars. Included in the costs are the direct costs of the mining and processing operations as well as direct mine-site overheads, amortization and depreciation. Materials and supplies inventories consist mostly of equipment parts and other consumables required in the mining and ore processing activities. All inventories are valued at the lower of average cost or net realizable value. |
Property, plant and equipment | Property, plant and equipment Property, plant and equipment assets, including machinery, processing equipment, mining equipment, mine site facilities, buildings, vehicles and expenditures that extend the life of such assets, are initially recorded at cost including acquisition and installation costs. Property, plant and equipment are subsequently measured at cost, less accumulated depreciation and accumulated impairment losses. The costs of self-constructed assets include direct construction costs and direct overhead during the construction phase. Indirect overhead costs are not included in the cost of self-constructed assets. Depreciation for mobile equipment and other assets having estimated lives shorter than the estimated life of the ore reserves is calculated using the straight-line method at rates which depreciate the cost of the assets, less their anticipated residual values, if any, over their estimated useful lives. Mobile mining equipment is amortized over a five year life. Assets, such as processing plants, power generators and buildings, which have an estimated life equal to or greater than the estimated life of the ore reserves, are amortized over the life of the proven and probable reserves of the associated mining property using a units-of-production amortization method, less their anticipated residual values, if any. The net book value of property, plant and equipment assets is charged against income if the mine site is abandoned and it is determined that the assets cannot be economically transferred to another project or sold. The residual values, useful lives and method of depreciation of property, plant and equipment are reviewed at each reporting period end, and adjusted prospectively if appropriate. Gains and losses on the disposal of an item of property, plant and equipment are determined by comparing the proceeds from disposal with the carrying amount, and are recognized net in the consolidated statement of operations. |
Mining properties | Mining properties Mining property assets, including property acquisition costs, tailings storage facilities, mine-site development and drilling costs where proven and probable reserves have previously been established, pre-production waste stripping, condemnation drilling, roads, feasibility studies and wells are recorded at cost. The costs of self-constructed assets include direct construction costs, direct overhead costs and allocated interest during the construction phase. Indirect overhead costs are not included in the cost of self-constructed assets. Mining property assets are amortized over the life of the proven and probable reserves to which they relate, using a units-of-production amortization method. At open pit mines the costs of removing overburden from an ore body in order to expose ore during its initial development period are capitalized. Mineral reserves and resources Determining mineral reserves and resources is a complex process involving numerous variables and is based on a professional evaluation using accepted international standards for the assessment of mineral reserves. Estimation is a subjective process, and the accuracy of such estimates is a function of the quantity and quality of available data, the assumptions made and judgments used in engineering and geological interpretation. Mineral reserve estimation may vary as a result of changes in the price of gold, production costs, and with additional knowledge of the ore deposits and mining conditions. Differences between management's assumptions including economic assumptions such as metal prices and market conditions could have a material effect in the future on the Company's results and financial position, particularly a change in the rate of depreciation and amortization of the related mining assets and the recognition of deferred revenue. |
Underground mine development costs | Underground mine development costs Underground mine development costs include development costs to build new shafts, drifts and ramps that will enable the Company to physically access ore underground. The time over which the Company will continue to incur these costs depends on the mine life. These underground development costs are capitalized as incurred. Capitalized underground development costs incurred to enable access to specific ore blocks or areas of the underground mine, and which only provide an economic benefit over the period of mining that ore block or area, are depreciated on a units-of-production basis, whereby the denominator is estimated ounces of gold in proven and probable reserves and the portion of resources within that ore block or area that is considered probable of economic extraction. If capitalized underground development costs provide an economic benefit over the entire mine life, the costs are depreciated on a units-of-production basis, whereby the denominator is the estimated ounces of gold in total accessible proven and probable reserves and the portion of resources that is considered probable of economic extraction. |
Borrowing costs | Borrowing costs Borrowing costs attributable to the acquisition, construction or production of a qualifying asset are capitalized. Qualifying assets are assets that require a significant amount of time to prepare for their intended use, including projects that are in the exploration and evaluation, development or construction stages. Capitalized borrowing costs are considered an element of the cost of the qualifying asset which is determined based on gross expenditures incurred on an asset. Capitalization ceases when the asset is substantially complete or if active development is suspended or ceases. Where the funds used to finance a qualifying asset form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to the relevant borrowings during the period. Where funds borrowed are directly attributable to a qualifying asset, the amount capitalized represents the borrowing costs specific to those borrowings. Other borrowing costs are recognized as an expense in the period in which they are incurred. |
Impairment of long-lived assets | Impairment of long-lived assets The Company assesses at each reporting period whether there is an indication that an asset or group of assets may be impaired. When impairment indicators exist, the Company estimates the recoverable amount of the asset and compares it against the asset's carrying amount. The recoverable amount is the higher of its fair value less cost of disposal ("FVLCD") and the asset's value in use ("VIU"). If the carrying amount exceeds the recoverable amount, an impairment loss is recorded in the consolidated statement of operations. In assessing VIU, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset not already reflected in the estimates of future cash flows. The cash flows are based on best estimates of expected future cash flows from the continued use of the asset and its eventual disposal. FVLCD is best evidenced if obtained from an active market or binding sale agreement. Where neither exists, the fair value is based on the best estimates available to reflect the amount that could be received from an arm's length transaction. Future cash flows are based on estimated quantities of gold and other recoverable metals, expected price of gold (considering current and historical prices, price trends and related factors), production levels and cash costs of production, capital and reclamation costs, all based on detailed engineered life-of-mine plans. Numerous factors including, but not limited to, unexpected grade changes, gold recovery variances, shortages of equipment and consumables, and equipment failures could impact our ability to achieve forecasted production schedules from proven and probable reserves. Additionally, commodity prices, capital expenditure requirements and reclamation costs could differ from the assumptions used in the cash flow models used to assess impairment. The ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral interests involves further risks in addition to those factors applicable to mineral interests where proven and probable reserves have been identified, due to the lower level of confidence that the identified mineralized material can ultimately be mined economically. If an impairment loss reverses in a subsequent period, the carrying amount (post reversal) of the related asset is increased to the revised estimate of recoverable amount to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset previously. Reversals of impairment losses are recognized in the statement of operations in the period the reversals occur. Material changes to any of the factors or assumptions discussed above could result in future asset impairments. Carrying value of assets and impairment charges The Company undertakes a review of its assets at each reporting period to determine whether any indication of impairment exists. Where an indicator of impairment exists, a formal estimate of the recoverable amount of the asset or cash-generating unit ("CGU") is made, which is considered to be the higher of its FVLCD and VIU. An impairment loss is recognized when the carrying value of the asset or CGU is higher than the recoverable amount. In undertaking this review, management of the Company is required to make significant estimates of, amongst other things, discount rates, future production and sale volumes, metal prices, reserves and resource quantities, future operating and capital costs and reclamation costs to the end of the mine's life. These estimates are subject to various risks and uncertainties, which may ultimately have an effect on the expected recoverability of the carrying values of the asset or CGU. In determining a CGU, management has examined the smallest identifiable group of assets that generates cash inflows that are largely independent of cash inflows from other assets or group of assets. Assessment of impairment and reverse impairment indicators Management applies significant judgment in assessing whether indicators of impairment or reverse impairment exist for an asset or group of assets which would necessitate impairment testing. Internal and external factors such as significant changes in the use of the asset, commodity prices and production costs are used by Management in determining whether there are any indicators. |
Rehabilitation provisions | Rehabilitation provisions The Company records a liability and corresponding asset for the present value of the estimated costs of legal and constructive obligations for future site reclamation and closure where the liability is probable and a reasonable estimate can be made of the obligation. The estimated present value of the obligation is reassessed on a periodic basis or when new material information becomes available. Increases or decreases to the obligation usually arise due to changes in legal or regulatory requirements, the extent of environmental remediation required, methods of reclamation, cost estimates, inflation rates, or discount rates. Changes to the provision for reclamation and remediation obligations related to operating mines, which are not the result of current production of inventory, are recorded with an offsetting change to the related asset. Changes to the provision for reclamation and remediation obligations related to suspended mine operations are recognized in the consolidated statements of operations and comprehensive loss. The present value is determined based on current market assessments of the time value of money using discount rates based on the risk-free rate maturing approximating the timing of expected expenditures to be incurred, and adjusted for country related risks. The periodic unwinding of the discount is recognized in the consolidated statement of operations as a finance expense. Rehabilitation provisions Environmental reclamation and closure liabilities are recognized at the time of environmental disturbance, in amounts equal to the discounted value of expected future reclamation and closure costs. The estimated future cash costs of such liabilities are based primarily upon environmental and regulatory requirements of the various jurisdictions in which we operate as well as any other constructive obligations that exist. The liability represents management's best estimates of cash required to settle the liability, inflation, assumptions of risks associated with future cash flows and the applicable risk-free interest rates for discounting the future cash outflow. The liability is reassessed and remeasured at each reporting date. |
Deferred revenue | Deferred revenue From January 1, 2018, deferred revenue consists of: 1) initial cash payments received by the Company for future delivery of payable gold under the terms of the Company’s Streaming Agreement as defined in Note 11 , Deferred Revenue, and 2) a significant financing component of the Company’s Streaming Agreement. Deferred revenue is increased as interest expense is recognized based on the implicit interest rate of the discounted cash flows arising from the expected delivery of ounces under the Company’s Streaming Agreement. The amount by which the deferred revenue balance is reduced and recognized into revenue is based on a rate per ounce of gold delivered under the stream. This rate per ounce of gold delivered relating to the payments received by the Company is based on the remaining deferred revenue balance divided by the ounces that are expected to be delivered over the term of the Stream Agreement. As the Company’s Streaming Agreement contains a variable component, IFRS 15 requires that the transaction price be updated and re-allocated on an ongoing basis. As a result, the deferred revenue recognized per ounce of gold delivered under the Streaming Agreement will require an adjustment each time there is a significant change in the underlying gold production profile of a mine. Should a change in the transaction price be necessary, a cumulative catch-up adjustment to revenue will be made in the period in which the change occurs, to reflect the updated production profile expected to be delivered under the Streaming Agreement. Deferred revenue Significant judgment is required in determining the appropriate accounting for the Streaming Agreement that has been entered into. Management has determined that based on the agreements reached that it assumes significant business risk associated with the timing and amount of ounces of gold being delivered. As such, the deposits received have been recorded as deferred revenue liabilities in the consolidated balance sheet. The amount by which the deferred revenue balance is reduced and recognized into revenue is based on a rate per ounce of gold delivered under the stream. This rate per ounce of gold delivered relating to the payments received by the Company is based on the remaining deferred revenue balance divided by the ounces that are expected to be delivered over the term of the Stream Agreement. As the Company’s Streaming Agreement contains a variable component, IFRS 15 requires that the transaction price be updated and re-allocated on an ongoing basis. As a result, the deferred revenue recognized per ounce of gold delivered under the Streaming Agreement will require an adjustment each time there is a significant change in the underlying gold production profile of a mine. Should a change in the transaction price be necessary, a retroactive adjustment to revenue will be made in the period in which the change occurs, to reflect the updated production profile expected to be delivered under the Streaming Agreement. |
Foreign currency transactions | Foreign currency transactions The Company's presentation currency of its consolidated financial statements is the U.S. dollar, as is the functional currency of its operations. The functional currency of all consolidated subsidiaries is the U.S. dollar. All values are rounded to the nearest thousand, unless otherwise stated. Monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at period end exchange rates. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are translated into U.S. dollars at the exchange rate at the date that the fair value was determined. Income and expense items are translated at the exchange rate in effect on the date of the transaction. Exchange gains and losses resulting from the translation of these amounts are included in net loss, except those arising on the translation of equity investments at fair value through other comprehensive income that are recorded in other comprehensive income. Non-monetary assets and liabilities denominated in foreign currencies that are measured at historical cost are translated at the exchange rate in effect at the transaction date . |
Income taxes | Income taxes Income taxes comprise the provision for (or recovery of) taxes actually paid or payable (current taxes) and for deferred taxes. Current taxes are based on taxable earnings in the year. Current tax is calculated using tax rates and laws that were enacted or substantively enacted at the balance sheet date in the respective jurisdictions. Current income tax assets and current income tax liabilities are only offset if a legally enforceable right exists to offset the amounts and the Company intends to settle on a net basis or to realize the asset and settle the liability simultaneously. Deferred income tax assets and liabilities are recognized for the expected future tax consequences attributable to temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements. Deferred income tax assets and liabilities are computed using enacted or substantially enacted income tax rates in effect when the temporary differences are expected to reverse. The effect on the deferred tax assets and liabilities of a change in tax rates is recognized in the period of substantial enactment. The provision for or the recovery of deferred taxes is based on the changes in deferred tax assets and liabilities during the period. The carrying amount of deferred income tax assets or liabilities are reviewed at the end of each reporting period and recognized to the extent that it is probable that taxable earnings will be available against which deductible temporary differences can be utilized. Income taxes We deal with uncertainties and judgments in the application of complex tax regulations in the various jurisdictions where our properties are located. The amount of taxes paid is dependent upon many factors, including negotiations with taxing authorities in the various jurisdictions and resolution of disputes arising from our international tax audits. We recognize potential liabilities and record tax liabilities for anticipated tax audit issues in our various tax jurisdictions based on our best estimate of additional taxes payable. We adjust these tax estimates in light of changing facts and circumstances, however, due to the complexity of some of these uncertainties, the ultimate resolution may result in payment that is materially different from our estimates of our tax liabilities. If our estimate of tax liability proves to be less than the ultimate assessment, an additional charge to expense would result. If the estimate of tax liabilities proves to be greater that the ultimate assessment, a tax benefit is recognized. A deferred tax asset is recognized to the extent that it is probable that taxable earnings will be available against which deductible temporary differences can be utilized. |
Net income/(loss) per share | Net income/(loss) per share Basic income/(loss) per share of common stock is calculated by dividing income available to Golden Star's common shareholders by the weighted average number of common shares issued and outstanding during the period. In periods with earnings, the calculation of diluted net income per common share uses the treasury stock method to compute the dilutive effects of stock options, convertible debentures and other potentially dilutive instruments. In periods of loss, diluted net loss per share is equal to basic loss per share. |
Revenue recognition | Revenue recognition Revenue from the sale of metal is recognized when the Company transfers control over to a customer. All of our spot sales of gold are transported to a South African gold refiner who locates a buyer and arranges for sale of our gold on the same day that the gold is shipped from the mine site. The sales price is based on the London P.M. fix on the day of shipment. Revenue recognition for the Company’s Streaming Agreement is disclosed in the accounting policy for deferred revenue. |
Share-based compensation | Share-based compensation Under the Company's Fourth Amended and Restated 1997 Stock Option Plan, common share options may be granted to executives, employees, consultants and non-employee directors. Compensation expense for such grants is recorded in the consolidated statements of operations and comprehensive loss, with a corresponding increase recorded in the contributed surplus account in the consolidated balance sheet. The expense is based on the fair value of the option at the time of grant, measured by reference to the fair value determined using a Black-Scholes valuation model, and is recognized over the vesting periods of the respective options on a graded basis. Consideration paid to the Company on exercise of options is credited to share capital. Under the Company's Deferred Share Unit ("DSU") plan, DSUs may be granted to executive officers and directors. Compensation expense for such grants is recorded in the consolidated statements of operations and comprehensive loss with a corresponding increase recorded in the contributed surplus account in the consolidated balance sheets. The expense is based on the fair values at the time of grant and is recognized over the vesting periods of the respective DSUs. Upon exercise the Company's compensation committee may, at its discretion, issue cash, shares or a combination thereof. Under the Company's Share Appreciation Rights ("SARs") plan allows SARs to be issued to executives, employees and directors. These awards are settled in cash on the exercise date equal to the Company's stock price less the strike price. Since these awards are settled in cash, the Company marks-to-market the associated expense for each award at the end of each reporting period using a Black-Scholes model. The Company accounts for these as liability awards and marks-to-market the fair value of the award until final settlement. Under the Company's Performance Share Units ("PSU") plan, PSUs may be granted to executives, employees and non-employee directors. Each PSU represents one notional common share that is redeemed for cash based on the value of a common share at the end of the three year performance period, to the extent performance and vesting criteria have been met. The PSUs vest at the end of a three year performance. The cash award is determined by multiplying the number of units by the performance adjusting factor, which ranges from 0% to 200% . The performance factor is determined by comparing the Company's share price performance to the share price performance of a peer group of companies as listed in the PSU plan. As the Company was required to settle these awards in cash, they were accounted for as liability awards with corresponding compensation expense recognized. The final PSU grant vested on December 31, 2018 and as a result the Company did not recognize a PSU expense in 2019. Under the Company's 2017 performance and restricted share unit plan (the "2017 PRSU Plan"), performance share units ("2017 PSUs") and restricted share units ("2017 RSUs" and, together with the 2017 PSUs, the "Share Units") may be issued to any employee or officer of the Company or its designated affiliates. Share Units may be redeemed for: (i) common shares issued from treasury; (ii) common shares purchased in the secondary market; (iii) a cash payment; or (iv) a combination of (i), (ii) and (iii). Each PRSU represents one notional common share that is redeemed for common shares or common shares plus cash subject to the consent of the Company based on the value of a common share at the end of the three year performance period, to the extent performance and vesting criteria have been met. The PRSUs vest at the end of a three year performance period. The award is determined by multiplying the number of Share Units by the performance adjustment factor, which ranges from 0% to 200% . The performance adjustment factor is determined by comparing the Company's share price performance to the share price performance of a peer group of companies as listed in the 2017 PRSU Plan. As the Company has a practice of settling these awards in common shares, they are accounted for as equity awards with corresponding compensation expense recognized. |
Right of Use Asset and Lease Liabilities | Right of Use Asset and Lease Liabilities Until December 31, 2018 leases that transfer substantially all of the benefits and risks of ownership to the Company were recorded as finance leases and classified as property, plant and equipment with a corresponding amount recorded with current and long-term debt. All other leases were classified as operating leases under which leasing costs were expensed in the period incurred. On January 1, 2019, the Company adopted the requirements of IFRS 16 Leases . As a result, the Company updated its accounting policy for leases to align with the requirements of IFRS 16. The Company elected to use the modified retrospective approach to initially adopt IFRS 16 which resulted in recognizing the cumulative effect of prior period amounts as an adjustment to the opening balance sheet through opening deficit on January 1, 2019. From January 1, 2019, the Company recognizes a lease liability and a right-of-use asset at the lease commencement date. The lease liability is initially measured as the present value of future lease payments discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, each operation’s applicable incremental borrowing rate. The incremental borrowing rate is the rate which the operation would have to pay to borrow, over a similar term and with a similar security, the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic environment. Lease payments included in the measurement of the lease liability comprise the following: fixed payments, including in-substance fixed payments, less any lease incentives receivable, variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date, amounts expected to be payable by the Company under residual value guarantees, the exercise price of a purchase option if the Company is reasonably certain to exercise that option, and payments of penalties for terminating the lease, if the Company expects to exercise an option to terminate the lease. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability, reducing the carrying amount to reflect lease payments made, and remeasuring the carrying amount to reflect any reassessment or lease modifications. The lease liability is remeasured when there is a change in future lease payments arising from a change in an index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option. The right-of-use asset is initially measured at cost, which comprises the following: the amount of the initial measurement of the lease liability, any lease payments made at or before the commencement date, less any lease incentives received, any initial direct costs incurred by the Company, and an estimate of costs to be incurred by the Company in dismantling and removing the underlying asset, restoring the site on which it is located or restoring the underlying asset to the condition required by the terms and conditions of the lease, unless those costs are incurred to produce inventories. The right-of-use asset is subsequently measured at cost, less any accumulated depreciation and any accumulated impairment losses, and adjusted for any remeasurement of the lease liability. It is depreciated in accordance with the Company’s accounting policy for plant and equipment, from the commencement date to the earlier of the end of its useful life or the end of the lease term. Each lease payment is allocated between the lease liability and finance cost. The finance cost is charged to net earnings over the lease period so as to produce a constant periodic rate of interest on the remaining balance of the liability for each period. On the consolidated balance sheet, right-of-use assets and lease liabilities are reported in mineral properties, plant and equipment and debt and lease liabilities, respectively. |
Financial instruments | Financial instruments The Company recognizes all financial assets initially at fair value and classifies them into one of the following measurement categories: fair value through profit or loss (“FVTPL”), fair value through other comprehensive income (“FVOCI”) or amortized cost, as appropriate. The Company recognizes all financial liabilities initially at fair value and classifies them as either FVTPL or loans and borrowings, as appropriate. The Company has not classified any of its derivatives as hedging instruments in an effective hedge. Derivatives From time to time the Company may utilize foreign exchange and commodity price derivatives to manage exposure to fluctuations in foreign currency exchange rates and gold prices, respectively. The Company does not employ derivative financial instruments for trading purposes or for speculative purposes. Derivative instruments are recorded on the balance sheet at fair value with changes in fair value recorded in the consolidated statement of operations. The Company did not have any foreign exchange derivatives outstanding at December 31, 2019 . 7% Convertible Debentures embedded derivative The Company's 7% Convertible Debentures embedded derivative is considered a financial instrument at FVTPL. The embedded derivative was recorded at fair value on the date of debt issuance. It is subsequently remeasured at fair value at each reporting date, and the changes in the fair value are recorded in the consolidated statement of operations. The fair value of the embedded derivative is determined using a convertible note valuation model, using assumptions based on market conditions existing at the reporting date. |
Share capital | Share capital Common shares are classified as equity. Costs directly attributable to the issue of new shares or share options are shown in equity as a deduction, net of tax, from the gross proceeds. |
Changes in accounting policies and standards, interpretations and amendments not yet effective | Changes in accounting policies The Company has adopted the following new and revised standards, effective January 1, 2019. These changes were made in accordance with the applicable transitional provisions. IFRS 16 Leases specifies how an IFRS reporter will recognize, measure, present and disclose leases. The standard provides a single lessee accounting model, requiring lessees to recognize assets and liabilities for all leases unless the lease term is 12 months or less or the underlying asset has a low value. Lessors continue to classify leases as operating or finance, with IFRS 16's approach to lessor accounting substantially unchanged from its predecessor, IAS 17. IFRS 16 was issued in January 2016 and applies to annual reporting periods beginning on or after January 1, 2019. On adoption of this standard the Company elected to use the modified retrospective approach to initially adopt IFRS 16 which resulted in recognizing the cumulative effect of prior period amounts as an adjustment to the opening balance sheet through opening deficit on January 1, 2019. Under IFRS 16, the Company recognized lease liabilities in relation to leases which had previously been classified as "operating leases" under the principles of IAS 17 Leases. These liabilities were measured at the present value of the remaining lease payments, discounted using the lessee’s incremental borrowing rate as of January 1, 2019. The weighted average lessee’s incremental borrowing rate applied to the lease liabilities on January 1, 2019 was 7.5% . The associated right-of-use assets for property leases were measured on a retrospective basis as if the new rules had always been applied. The change in accounting policy resulted in an increase to mining interests (plant and equipment) of $0.7 million and an increase to long term debt (finance leases) of $0.5 million . The net impact on retained earnings on January 1, 2019 was a decrease of $0.1 million . IFRIC 23 Uncertainty over income tax treatments clarifies how the recognition and measurement requirements of IAS 12, Income Taxes, are applied where there is uncertainty over income tax treatments effective for years beginning on or after January 1, 2019. There was no accounting impact to the financial statements on adoption of this standard. |
Units of production depreciation | Units of production depreciation The mineral properties and a large portion of the property, plant and equipment is depreciated/amortized using the units of production method over the expected operating life of the mine based on estimated recoverable ounces of gold, which are the prime determinants of the life of a mine. Estimated recoverable ounces of gold include proven and probable mineral reserves. Changes in the estimated mineral reserves will result in changes to the depreciation charges over the remaining life of the operation. A decrease in the mineral reserves would increase depreciation and amortization expense and this could have a material impact on the operating results. The amortization base is updated on an annual basis based on the new mineral reserve and resource estimates. |
Fair value of financial instruments, including embedded derivatives | Fair value of financial instruments, including embedded derivatives Where the fair value of financial assets and financial liabilities recorded in the financial statements cannot be derived from active markets, their fair value is determined using valuation techniques including the discounted cash flow model. The inputs to these models are taken from observable markets where possible, but where this is not feasible, a degree of judgment is required in establishing fair values. The judgments include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments. When measuring the fair value of an asset or liability, the Company uses observable market data to the greatest extent possible. Fair values are categorized into different levels in a fair value hierarchy based on the inputs used in the valuation techniques as follows: Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities Level 2: inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices) Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs) |
