Basis of Presentation [Abstract]
Basis of Presentation	THE COMPANY Coeur Mining, Inc. (“Coeur” or “the Company”) is primarily a gold and silver producer with five operating mines located in the United States, Canada and Mexico and several exploration projects in North America. Coeur was incorporated as an Idaho corporation in 1928 under the name Coeur d’Alene Mines Corporation and on May 16, 2013, changed its state of incorporation from the State of Idaho to the State of Delaware and changed its name to Coeur Mining, Inc. Coeur’s corporate headquarters are in Chicago, Illinois. The cash flow and profitability of the Company's operations are significantly impacted by the market price of gold, silver, zinc and lead, which are affected by numerous factors beyond the Company's control.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Risks and uncertainties As a mining company, the revenue, profitability and future rate of growth of the Company are substantially dependent on the prevailing prices for gold, silver, zinc and lead. The prices of these metals are volatile and affected by many factors beyond the Company’s control, including prevailing interest rates and returns on other asset classes, expectations regarding inflation, speculation, currency values, governmental decisions regarding precious metals stockpiles, global and regional demand and production, political and economic conditions and other factors. A substantial or extended decline in commodity prices could have a material adverse effect on the Company’s financial position, results of operations, cash flows, access to capital and the quantities of reserves that the Company can economically produce. Further, the carrying value of the Company’s property, plant and equipment, net; mining properties, net; inventories and ore on leach pads are particularly sensitive to the outlook for commodity prices. A decline in the Company’s price outlook from current levels could result in material impairment charges related to these assets. Use of Estimates The Company's Consolidated Financial Statements have been prepared in accordance with United States Generally Accepted Accounting Principles. The preparation of the Company's Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to metal prices and mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of production amortization calculations, environmental, reclamation and closure obligations, estimates of recoverable silver and gold in leach pad inventories, estimates of fair value for certain reporting units and asset impairments, valuation allowances for deferred tax assets, and the fair value and accounting treatment of financial instruments, equity securities, asset acquisitions, the allocation of fair value to assets and liabilities assumed in connection with business combinations, and derivative instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from the amounts estimated in these financial statements. Principles of Consolidation The Consolidated Financial Statements include the wholly-owned subsidiaries of the Company, the most significant of which are Coeur Mexicana S.A. de C.V., Coeur Rochester, Inc., Coeur Alaska, Inc., Wharf Resources (U.S.A.), Inc., Coeur Silvertip Holdings Ltd. All intercompany balances and transactions have been eliminated. Cash and Cash Equivalents Cash and cash equivalents include all highly-liquid investments with an original maturity of three months or less. The Company minimizes its credit risk by investing its cash and cash equivalents with major U.S. and international banks and financial institutions located principally in the United States with a minimum credit rating of A1, as defined by Standard & Poor’s. The Company’s management believes that no concentration of credit risk exists with respect to the investment of its cash and cash equivalents. At certain times, amounts on deposit may exceed federal deposit insurance limits. Receivables Trade receivables and other receivable balances are reported at outstanding principal amounts, net of an allowance for doubtful accounts, if deemed necessary. Management evaluates the collectability of receivable account balances to determine the allowance, if any. Management considers the other party's credit risk and financial condition, as well as current and projected economic and market conditions, in determining the amount of the allowance. Receivable balances are written off when management determines that the balance is uncollectible. Ore on Leach Pads The heap leach process extracts silver and gold by placing ore on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained silver and gold, which are then recovered in metallurgical processes. The Company uses several integrated steps to scientifically measure the metal content of ore placed on the leach pads. As the ore body is drilled in preparation for the blasting process, samples are taken of the drill residue which are assayed to determine estimated quantities of contained metal. The Company estimates the quantity of ore by utilizing global positioning satellite survey techniques. The Company then processes the ore through crushing facilities where the output is again weighed and sampled for assaying. A metallurgical reconciliation with the data collected from the mining operation is completed with appropriate adjustments made to previous estimates. The crushed ore is then transported to the leach pad for application of the leaching solution. As the leach solution is collected from the leach pads, it is continuously sampled for assaying. The quantity of leach solution is measured by flow meters throughout the leaching and precipitation process. After precipitation, the product is converted to doré at the Rochester mine and a form of gold concentrate at the Wharf mine, representing the final product produced by each mine. The inventory is stated at lower of cost or net realizable value, with cost being determined using a weighted average cost method. The historical cost of metal expected to be extracted within twelve months is classified as current and the historical cost of metals contained within the broken ore expected to be extracted beyond twelve months is classified as non-current. Ore on leach pads is valued based on actual production costs incurred to produce and place ore on the leach pad, less costs allocated to minerals recovered through the leach process. The estimate of both the ultimate recovery expected over time and the quantity of metal that may be extracted relative to the time the leach process occurs requires the use of estimates, which are inherently inaccurate due to the nature of the leaching process. The quantities of metal contained in the ore are based upon actual weights and assay analysis. The rate at which the leach process extracts gold and silver from the crushed ore is based upon laboratory testing and actual experience of more than twenty years of leach pad operations at the Rochester mine and thirty years of leach pad operations at the Wharf mine. The assumptions used by the Company to measure metal content during each stage of the inventory conversion process includes estimated recovery rates based on laboratory testing and assaying. The Company periodically reviews its estimates compared to actual experience and revises its estimates when appropriate. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis. Metal and Other Inventory Inventories include concentrate, doré, and operating materials and supplies. The classification of inventory is determined by the stage at which the ore is in the production process. All inventories are stated at the lower of cost or net realizable value, with cost being determined using a weighted average cost method. Concentrate and doré inventory includes product at the mine site and product held by refineries. Metal inventory costs include direct labor, materials, depreciation, depletion and amortization as well as overhead costs relating to mining activities. Property, Plant, and Equipment Expenditures for new facilities, assets acquired pursuant to capital leases, new assets or expenditures that extend the useful lives of existing facilities are capitalized and depreciated using the straight-line method at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such facilities, lease term, or the useful life of the individual assets. Productive lives range from 7 to 30 years for buildings and improvements and 3 to 10 years for machinery and equipment. Certain mining equipment is depreciated using the units-of-production method based upon estimated total proven and probable reserves. Mining Properties and Mine Development Capitalization of mine development costs begins once all operating permits have been secured, mineralization is classified as proven and probable reserves and a final feasibility study has been completed. Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Costs incurred before mineralization are classified as proven and probable reserves are capitalized if a project is in pre-production phase or expensed and classified as Exploration or Pre-development if the project is not yet in pre-production. Mine development costs are amortized using the units of production method over the estimated life of the ore body generally based on recoverable ounces to be mined from proven and probable reserves. Interest expense allocable to the cost of developing mining properties and to construct new facilities is capitalized until assets are ready for their intended use. Drilling and related costs incurred at the Company’s operating mines are expensed as incurred in Exploration, unless the Company can conclude with a high degree of confidence, prior to the commencement of a drilling program, that the drilling costs will result in the conversion of a mineralized material into proven and probable reserves. The Company’s assessment is based on the following factors: results from previous drill programs; results from geological models; results from a mine scoping study confirming economic viability of the resource; and preliminary estimates of mine inventory, ore grade, cash flow and mine life. In addition, the Company must have all permitting and/or contractual requirements necessary to have the right to and/or control of the future benefit from the targeted ore body. The costs of a drilling program that meet these criteria are capitalized as mine development costs. Drilling and related costs of approximately $7.5 million and $18.6 million at December 31, 2019 and 2018, respectively, were capitalized. The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Costs applicable to sales in the same period as the revenue from the sale of inventory. Mineral Interests Significant payments related to the acquisition of land and mineral rights are capitalized. Prior to acquiring such land or mineral rights, the Company generally makes a preliminary evaluation to determine that the property has significant potential to develop an economic ore body. The time between initial acquisition and full evaluation of a property’s potential is variable and is determined by many factors including: location relative to existing infrastructure, the property’s stage of development, geological controls and metal prices. If a mineable ore body is discovered, such costs are amortized when production begins using the units of- production method based on recoverable ounces to be mined from proven and probable reserves. If no mineable ore body is discovered, such costs are expensed in the period in which it is determined the property has no future economic value. Impairment of Long-lived Assets We review and evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Asset impairment is considered to exist if the total estimated undiscounted pretax future cash flows are less than the carrying amount of the asset. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of future cash flows from other asset groups. An impairment loss is measured by discounted estimated future cash flows, and recorded by reducing the asset's carrying amount to fair value. Future cash flows are estimated based on estimated quantities of recoverable minerals, expected gold, silver, lead and zinc prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. Existing proven and probable reserves and value beyond proven and probable reserves, including mineralization other than proven and probable reserves are included when determining the fair value of mine site asset groups at acquisition and, subsequently, in determining whether the assets are impaired. The term “recoverable minerals” refers to the estimated amount of gold, silver, lead and zinc that will be obtained after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from exploration stage mineral interests are risk adjusted based on management’s relative confidence in such materials. The ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral interests involves further risks in addition to those risk 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 could ultimately be mined economically. Assets classified as exploration potential have the highest level of risk that the carrying value of the asset can be ultimately realized, due to the still lower level of geological confidence and economic modeling. During the fourth quarter of 2019, the Company performed a comprehensive analysis of its Silvertip property and determined that indicators of impairment existed, primarily as a result of continued deterioration in zinc and lead market conditions as well as ongoing challenges related to the processing facility. As a result of the impairment indicators, a recoverability test was performed and the Company concluded that the long-lived assets for the Silvertip property was impaired. A non-cash impairment charge of $250.8 million was recorded during the fourth quarter of 2019. The write-down was allocated between Property, plant and equipment, net , Mining properties, net and Other non-current assets , in the amounts of $43.6 million , $201.5 million and $5.7 million , respectively. See Note 4 -- Impairment of Long-lived Assets and 16 -- Fair Value Measurements for additional detail of the impairment and assumptions used in the determination of the fair value of the long-lived assets tested for impairment. Properties Held for Sale In determining whether to classify a property as held for sale, the Company considers whether: (i) management has committed to a plan to sell the property; (ii) the investment is available for immediate sale, in its present condition; (iii) the Company has initiated a program to locate a buyer; (iv) the Company believes that the sale of the property is probable; (v) the Company has received a significant non-refundable deposit for the purchase of the property; (vi) the Company is actively marketing the property for sale at a price that is reasonable in relation to its estimated fair value; and (vii) actions required for the Company to complete the plan indicate that it is unlikely that any significant changes will be made to the plan. If all of the above criteria are met, the Company classifies the property as held for sale. When these criteria are met, the Company suspends depreciation on the properties held for sale. The properties held for sale and associated liabilities are classified separately on the consolidated balance sheets. Such properties are recorded at the lesser of the carrying value or estimated fair value less costs to sell. Additionally, if the sale represents a strategic shift that has (or will have) a major effect on the entity's results and operations, the assets, liabilities and operations for the periods presented are classified on the Consolidated Balance Sheets as held for sale and Consolidated Statements of Comprehensive Income (Loss) as discontinued operations for all periods presented. At December 31, 2017, the San Bartolomé mine met the held for sale criteria. Furthermore, considering that San Bartolomé was an operating mine and the sale represented an exit from the South American region, the Company determined that the expected disposal of Manquiri and the San Bartolomé mine through a sale of all of the issued and outstanding shares of Manquiri represented a strategic shift to a North America-focused mining portfolio that had a major effect on the entity's results and operations, therefore, the applicable assets, liabilities and operations for the periods presented are classified on the Consolidated Balance Sheets as held for sale and the Consolidated Statements of Comprehensive Income (Loss) as discontinued operations for all periods presented. Restricted Assets The Company, under the terms of its self-insurance and bonding agreements with certain banks, lending institutions and regulatory agencies, is required to collateralize certain portions of its obligations. The Company has collateralized these obligations by assigning certificates of deposit that have maturity dates ranging from three months to a year, to the respective institutions or agencies. At December 31, 2019 and 2018, the Company held certificates of deposit and cash under these agreements of $8.8 million and $12.3 million , respectively. The ultimate timing of the release of the collateralized amounts is dependent on the timing and closure of each mine and repayment of the facility. In order to release the collateral, the Company must seek approval from certain government agencies responsible for monitoring the mine closure status. Collateral could also be released to the extent the Company is able to secure alternative financial assurance satisfactory to the regulatory agencies. The Company believes there is a reasonable probability that the collateral will remain in place beyond a twelve-month period and has therefore classified these investments as long-term. Leases We determine if an arrangement is, or contains, a lease at the inception date. Operating leases are included in Other assets, non-current with the related liabilities included in Accrued liabilities and Other and Other long-term liabilities . Assets under finance leases, which primarily represent property and equipment , are included in Property, plant and equipment, net , with the related liabilities included in debt, current and debt, non-current on the Consolidated Balance Sheet. Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components which are accounted for as a single lease component. Reclamation The Company recognizes obligations for the expected future retirement of tangible long-lived assets and other associated asset retirement costs. The fair value of a liability for an asset retirement obligation will be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. An accretion cost, representing the increase over time in the present value of the liability, is recorded each period in Pre-development, reclamation, and other . As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced. Future remediation costs for inactive mines are accrued based on management’s best estimate at the end of each period of the discounted costs expected to be incurred at the site. Such cost estimates include, where applicable, ongoing care and maintenance and monitoring costs. Changes in estimates are reflected prospectively in the period an estimate is revised. Foreign Currency The assets and liabilities of the Company’s foreign subsidiaries are measured using U.S. dollars as their functional currency. Revenues and expenses are remeasured at the average exchange rate for the period. Foreign currency gains and losses are included in the determination of net income or loss. Derivative Financial Instruments The Company is exposed to various market risks, including the effect of changes in metal prices and interest rates, and uses derivatives to manage financial exposures that occur in the normal course of business. The Company may elect to designate certain derivatives as hedging instruments under U.S. GAAP. The Company, from time to time, uses derivative contracts to protect the Company’s exposure to fluctuations in metal prices. The Company has elected to designate these instruments as cash flow hedges of forecasted transactions at their inception. Assuming normal market conditions, the change in the market value of such derivative contracts has historically been, and is expected to continue to be, highly effective at offsetting changes in price movements of the hedged item. For derivatives not designated as hedging instruments, the Company recognizes derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. Changes in the value of derivative instruments not designated as hedging instruments are recorded each period in the Consolidated Statement of Comprehensive Income (Loss) in Fair value adjustments, net or Revenue . Management applies judgment in estimating the fair value of instruments that are highly sensitive to assumptions regarding commodity prices, market volatilities, and foreign currency exchange rates. See Note 17 -- Derivative Financial Instruments and Hedging Activities for additional information. Stock-based Compensation The Company estimates the fair value of stock options using the Black-Scholes option pricing model and stock appreciation rights (“SARs”) awards using market comparison. Stock options granted are accounted for as equity-based awards and SARs are accounted for as liability-based awards. The value of the SARs is remeasured at each reporting date. The Company estimates forfeitures of stock-based awards based on historical data and periodically adjusts the forfeiture rate. The adjustment of the forfeiture rate is recorded as a cumulative adjustment in the period the forfeiture estimate is changed. Compensation costs related to stock based compensation are included in General and administrative expenses , Costs applicable to sales , and Property, plant, and equipment, net as deemed appropriate. The fair value of restricted stock is based on the Company's stock price on the date of grant. The fair value of performance leverage stock units (“PSUs”) with market conditions is determined using a Monte Carlo simulation model. Stock based compensation expense related to awards with a market or performance condition is generally recognized over the vesting period of the award utilizing the graded vesting method, while all other awards are recognized on a straight-line basis. The Company's estimates may be impacted by certain variables including, but not limited to, stock price volatility, employee stock option exercise behaviors, additional stock option grants, estimates of forfeitures, the Company's performance, and related tax impacts. Income and Mining Taxes The Company uses an asset and liability approach which results in the recognition of deferred tax liabilities and assets for the expected future tax consequences or benefits of temporary differences between the financial reporting basis and the tax basis of assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. A valuation allowance has been provided for the portion of the Company’s net deferred tax assets for which it is more likely than not that they will not be realized. Revenue Recognition The Company produces doré and concentrate that is shipped to third-party refiners and smelters, respectively, for processing. The Company enters into contracts to sell its metal to various third-party customers which may include the refiners and smelters that process the doré and concentrate. The Company’s performance obligation in these transactions is generally the transfer of metal to the customer. In the case of doré shipments, the Company generally sells refined metal at market prices agreed upon by both parties. The Company also has the right, but not the obligation, to sell a portion of the anticipated refined metal in advance of being fully refined. When the Company sells refined metal or advanced metal, the performance obligation is satisfied when the metal is delivered to the customer. Revenue and Costs Applicable to Sales are recorded on a gross basis under these contracts at the time the performance obligation is satisfied. Under the Company’s concentrate sales contracts with third-party smelters, metal prices are set on a specified future quotational period, typically one to three months, after the shipment date based on market prices. When the Company sells gold concentrate to the third-party smelters, the performance obligation is satisfied when the concentrate is loaded onto the third-party shipping vessel. The contracts, in general, provide for provisional payment based upon provisional assays and historical metal prices. Final settlement is based on the applicable price for the specified future quotational period and generally occurs three to six months after shipment. The Company’s provisionally priced sales contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of concentrates measured at the forward price at the time of sale. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through revenue each period until the date of final metal settlement. The Company also sells concentrate under off-take agreements to third-party customers that are responsible for arranging the smelting of the concentrate. Prices can be either be fixed or based on a quotational period. The quotational period varies by contract, but is generally a one-month period following the shipment of the concentrate. The performance obligation is satisfied when the concentrate is loaded onto the third-party shipping vessel. The off-take agreement allows for the Company to sell concentrate in advance of shipment and results in the customer taking ownership of the concentrate prior to shipment. The Company recognizes revenue from concentrate sales, net of treatment and refining charges, when it satisfies the performance obligation of transferring control of the concentrate to the customer. For doré and off-take sales, the Company may incur a finance charge related to advance sales that is not considered significant and, as such, is not considered a separate performance obligation. In addition, the Company has elected to treat freight costs as a fulfillment cost under ASC 606 and not as a separate performance obligation. The Company’s gold stream agreement with a subsidiary of Franco-Nevada Corporation (“Franco-Nevada”) provided for a $20.0 million deposit paid by Franco-Nevada in exchange for the right and obligation, commencing in 2016, to purchase 50% of a portion of Palmarejo gold production at the lesser of $800 or market price per ounce. Because there is no minimum obligation associated with the deposit, it is not considered financing, and each shipment is considered to be a separate performance obligation. The streaming agreement represents a contract liability under ASC 606, which requires the Company to ratably recognize a portion of the deposit as revenue for each gold ounce delivered to Franco-Nevada. The following table presents a rollforward of the Franco-Nevada contract liability balance: Year ended December 31, In thousands 2019 2018 2017 Opening Balance $ 12,918 $ 14,883 $ 19,281 Revenue Recognized (1,857 ) (1,965 ) (4,398 ) Closing Balance $ 11,061 $ 12,918 $ 14,883 In December 2019, the Company received a $15.0 million prepayment for deliveries of gold concentrate from the Kensington mine pursuant to the Amended Sales Contract (as defined below). The Company expects to recognize the full value of the accrued liability by June 2020 when it satisfies the performance obligation of transferring control of the concentrate to the customer. See Note 21 -- Commitments and Contingencies for additional detail. Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, “ Leases, ” which required lessees to recognize assets and liabilities for the rights and obligations created by most leases on the balance sheet. These changes became effective for the Company’s fiscal year beginning January 1, 2019 and the Company adopted it using the cumulative-effect adjustment transition method approved by the FASB in July 2018, which did not require the Company to recast the comparative periods presented when transitioning to the new guidance on January 1, 2019. The Company elected to utilize the transition related practical expedients permitted by the new standard. In addition to existing capital leases and other financing obligations, the adoption of the new standard resulted in the recognition of additional right-of-use assets and lease liabilities related to operating leases of approximately $65.0 million . These changes did not materially impact the Company’s consolidated net income, financial position or cash flows. Recently Issued Accounting Standards In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326)”. The new standard is effective for reporting periods beginning after December 15, 2019. The standard replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. The standard requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We plan to adopt the new credit loss standard effective January 1, 2020. We do not expect the new credit loss standard to have a material effect on our financial position, results of operations or cash flows. In December 2019, the FASB issued ASU 2019-12, “Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740)” which is intended to

Segment Reporting [Abstract]
SEGMENT REPORTING	SEGMENT REPORTING The Company’s operating segments include the Palmarejo complex, and the Rochester, Kensington, Wharf and Silvertip mines. Except for the Silvertip mine, all operating segments are engaged in the discovery, mining, and production of gold and/or silver. The Silvertip mine is engaged in the discovery, mining, and production of silver, zinc and lead. Silvertip commenced commercial production in September 2018. Other includes the Sterling/Crown project and La Preciosa project, other mineral interests, strategic equity investments, corporate office, elimination of intersegment transactions, and other items necessary to reconcile to consolidated amounts. The Company determined that the disposition in the first quarter of 2018 of Empresa Minera Manquiri S.A., a Bolivian Sociedad anonima (“Manquiri”), which operates the San Bartolomé mine, represented a strategic shift to a North America-focused mining portfolio and had significant effect on the entity's results and operations; therefore, the results of operations are presented as discontinued operations in Other for all periods presented. Financial information relating to the Company’s segments is as follows (in thousands): Year ended December 31, 2019 Palmarejo Rochester Kensington Wharf Silvertip (3) Other Total Revenue Gold sales $ 141,669 $ 50,225 $ 181,111 $ 120,342 $ — $ — $ 493,347 Silver sales 111,032 61,799 — 1,072 17,575 — 191,478 Zinc sales — — — — 12,806 — 12,806 Lead sales — — — — 13,871 — 13,871 Metal sales 252,701 112,024 181,111 121,414 44,252 — 711,502 Costs and Expenses Costs applicable to sales (1) 141,927 100,205 119,602 80,689 108,758 — 551,181 Amortization 59,379 18,041 50,592 12,280 36,738 1,846 178,876 Exploration 5,658 657 5,588 272 2,469 7,883 22,527 Write-downs — — — — 250,814 — 250,814 Other operating expenses 4,591 4,572 1,248 2,832 1,216 38,455 52,914 Other income (expense) Loss on debt extinguishment — — — — — (1,281 ) (1,281 ) Fair value adjustments, net — — — — — 16,030 16,030 Interest expense, net (444 ) (1,015 ) (1,333 ) (100 ) (1,137 ) (20,742 ) (24,771 ) Other, net (4,798 ) (378 ) (704 ) 89 (557 ) 3,155 (3,193 ) Income and mining tax (expense) benefit (14,257 ) (709 ) — (3,041 ) 32,084 (2,948 ) 11,129 Income (loss) from continuing operations $ 21,647 $ (13,553 ) $ 2,044 $ 22,289 $ (325,353 ) $ (53,970 ) $ (346,896 ) Income (loss) from discontinued operations $ — $ — $ — $ — $ — $ 5,693 $ 5,693 Segment assets (2) $ 319,292 $ 284,878 $ 194,076 $ 84,765 $ 164,125 $ 168,647 $ 1,215,783 Capital expenditures $ 32,658 $ 22,592 $ 23,513 $ 2,220 $ 17,504 $ 1,285 $ 99,772 (1) Excludes amortization (2) Segment assets include receivables, prepaids, inventories, property, plant and equipment, and mineral interests (3) Subsequent to the end of the period covered by this Report, the Company made the decision to temporarily suspend mining and processing activities at Silvertip as a result of further deterioration in zinc and lead market conditions as well as processing facility-related challenges. The Company plans to (i) double its exploration investment in 2020 to potentially further expand the mineralized material and extend the mine life, and (ii) pursue a mill expansion to improve the asset’s cost structure and its ability to deliver sustainable cash flow Year ended December 31, 2018 Palmarejo Rochester Kensington Wharf Silvertip Other Total Revenue Gold sales $ 131,758 $ 66,556 $ 132,924 $ 95,770 — $ — $ 427,008 Silver sales 113,998 75,252 — 746 3,157 — 193,153 Zinc sales — — — — 3,612 — 3,612 Lead sales — — — — 2,131 — 2,131 Metal sales 245,756 141,808 132,924 96,516 8,900 — 625,904 Costs and Expenses Costs applicable to sales (1) 120,088 105,677 112,364 67,201 35,620 — 440,950 Amortization 60,744 20,909 29,508 11,072 5,235 1,005 128,473 Exploration 10,516 332 5,871 104 2,748 5,826 25,397 Other operating expenses 3,043 7,071 1,721 2,686 303 36,564 51,388 Other income (expense) Fair value adjustments, net — — — — — 3,638 3,638 Interest expense, net (2,137 ) (466 ) (973 ) (40 ) (766 ) (19,982 ) (24,364 ) Other, net (8,308 ) (1,211 ) 2,795 (834 ) (370 ) (16,777 ) (24,705 ) Income and mining tax (expense) benefit (15,724 ) (874 ) — (1,063 ) 16,057 18,384 16,780 Income (loss) from continuing operations $ 25,196 $ 5,268 $ (14,718 ) $ 13,516 $ (20,085 ) $ (58,132 ) $ (48,955 ) Income (loss) from discontinued operations $ — $ — $ — $ — — $ 550 $ 550 Segment assets (2) $ 363,024 $ 269,903 $ 224,460 $ 102,246 415,998 $ 175,040 $ 1,550,671 Capital expenditures $ 29,425 $ 9,919 $ 44,738 $ 3,382 52,932 $ 391 $ 140,787 (1) Excludes amortization (2) Segment assets include receivables, prepaids, inventories, property, plant and equipment, and mineral interests Year ended December 31, 2017 Palmarejo Rochester Kensington Wharf Silvertip Other Total Revenue Gold sales $ 146,187 $ 68,964 $ 154,469 $ 124,629 — $ — $ 494,249 Silver sales 128,622 83,716 — 1,272 — 1,739 215,349 Metal sales 274,809 152,680 154,469 125,901 — 1,739 709,598 Costs and Expenses Costs applicable to sales (1) 146,176 107,921 116,096 69,322 — 745 440,260 Amortization 73,744 22,306 36,022 13,012 — 1,465 146,549 Exploration 11,924 1,352 8,604 320 — 8,111 30,311 Other operating expenses 1,263 3,394 1,412 2,468 153 43,862 52,552 Other income (expense) Loss on debt extinguishment — — — — — (9,342 ) (9,342 ) Fair value adjustments, net — (864 ) — — — — (864 ) Interest expense, net (487 ) (496 ) (413 ) (66 ) (2,212 ) (12,766 ) (16,440 ) Other, net (851 ) 2,193 (922 ) 172 1,142 24,909 26,643 Income and mining tax (expense) benefit (24,330 ) (1,028 ) — (3,936 ) (932 ) 1,228 (28,998 ) Income (loss) from continuing operations $ 16,034 $ 17,512 $ (9,000 ) $ 36,949 $ (2,155 ) $ (48,415 ) $ 10,925 Income (loss) from discontinued operations $ — $ — $ — $ — — $ (12,244 ) $ (12,244 ) Segment assets (2) $ 377,621 $ 239,223 $ 212,588 $ 104,010 339,369 $ 71,742 $ 1,344,553 Capital expenditures $ 29,902 $ 40,874 $ 36,248 $ 8,844 17,684 $ 3,182 $ 136,734 (1) Excludes amortization (2) Segment assets include receivables, prepaids, inventories, property, plant and equipment, and mineral interests Assets December 31, 2019 December 31, 2018 Total assets for reportable segments $ 1,215,783 $ 1,550,671 Cash and cash equivalents 55,645 115,081 Other assets 107,208 46,748 Total consolidated assets $ 1,378,636 $ 1,712,500 Geographic Information Long-Lived Assets December 31, 2019 December 31, 2018 United States $ 494,286 $ 515,649 Mexico 312,168 342,007 Canada 146,804 404,185 Other 7,486 8,177 Total $ 960,744 $ 1,270,018 Revenue Year ended December 31, 2019 2018 2017 United States $ 414,548 $ 371,248 $ 433,050 Mexico 252,701 245,756 274,809 Canada 44,253 8,900 — Australia — — 1,739 Total $ 711,502 $ 625,904 $ 709,598 The Company's doré, as well as the concentrate product produced by the Wharf mine, is refined into gold and silver bullion according to benchmark standards set by the LBMA, which regulates the acceptable requirements for bullion traded in the London precious metals markets. The Company then sells its gold and silver bullion to multi-national banks, bullion trading houses, and refiners across the globe. The Company had eight trading counterparties at December 31, 2019. The Company's sales of doré or concentrate product produced by the Palmarejo, Rochester, and Wharf mines amounted to approximately 68% , 77% , and 78% of total metal sales for the years ended December 31, 2019, 2018, and 2017, respectively. In November 2018, one of the refiners of the Company’s doré, RMC, a U.S.-based precious metals refiner, filed for protection under Chapter 11 of the United States Bankruptcy Code. See Note 5 -- Receivables for additional detail. The Company's gold concentrate product from the Kensington mine and the zinc and lead concentrates from the Silvertip mine are sold under a variety of agreements with smelters and traders, and the smelters and traders pay the Company for the metals recovered from the concentrates. The Company’s sales of concentrate produced by the Kensington and Silvertip mines amounted to approximately 32% , 23% , and 22% of total metal sales for the years ended December 31, 2019, 2018, and 2017, respectively. The Company believes that the loss of any one smelter, refiner, trader or third-party customer would not materially adversely affect the Company due to the liquidity of the markets and current availability of alternative trading counterparties.

Impairment or Disposal of Tangible Assets Disclosure [Abstract]
Asset Impairment Charges [Text Block]	IMPAIRMENT OF LONG-LIVED ASSETS During the fourth quarter of 2019, the Company performed a comprehensive analysis of its Silvertip property and determined that indicators of impairment existed, primarily as a result of further deterioration in zinc and lead market conditions as well as processing facility-related challenges. As a result of the impairment indicators, a recoverability test was performed and the Company concluded that the carrying value of the long-lived assets for the Silvertip property was impaired. A non-cash impairment charge of $250.8 million was recorded during the fourth quarter of 2019. The write-down was allocated between Property, plant and equipment, net , Mining properties, net and Other non-current assets , $43.6 million , $201.5 million and $5.7 million , respectively. Subsequent to the end of the period covered by this Report, the Company made the decision to temporarily suspend active mining and processing activities. The Company plans to (i) double its exploration investment in 2020 to potentially further expand the mineralized material and extend the mine life, and (ii) pursue a mill expansion to improve the asset’s cost structure and its ability to deliver sustainable cash flow. See Note 16 -- Fair Value Measurements for additional detail of the assumptions used in the determination of the fair value of the long-lived assets tested for impairment.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS In November 2018, the Company and Coeur Rochester consummated the transactions contemplated by the Asset Purchase Agreement among the Company, Coeur Rochester and Alio Gold Inc. and one of its subsidiaries (“Alio Gold”) pursuant to which Coeur Rochester acquired all of Alio Gold’s rights, titles, and interests in and to certain real property assets and patented and unpatented mining claims located in Pershing County, Nevada (collectively, the “Lincoln Hill and related assets”). In consideration for the acquisition of Lincoln Hill and related assets, the Company paid Alio Gold consideration of $19.0 million in shares of Company common stock calculated using a five-day volume-weighted average price of Company common stock for a five-trading day period ending on the third trading day immediately preceding the closing. The transaction was accounted for as an asset acquisition as the Lincoln Hill and related assets do not currently have processes, including experienced personnel, in place to extract the minerals from the ground to produce outputs. As such, the total purchase price was allocated to the assets acquired and liabilities assumed based on their relative fair values. The purchase price and acquired assets and liabilities were as follows (in thousands except share data): Common shares issued (4,268,703 at $4.40) $ 18,782 Transaction advisory fees and other acquisition costs 246 Total purchase price $ 19,028 Total assets acquired $ 19,028 In October 2018, the Company completed its acquisition of Northern Empire, whose principal asset is the Sterling/Crown gold project. Upon completion of the acquisition, each share of Northern Empire common stock issued and outstanding immediately prior to the effective time of the Plan of Arrangement, excluding shares owned by the Company, was exchanged for shares of the Company’s common stock at a ratio of 0.1850 shares of Company common stock for each Northern Empire common share. Approximately 12.1 million Coeur shares were issued to Northern Empire shareholders (other than the Company) upon closing of the acquisition, representing aggregate value of approximately $73.6 million as of the closing date. Prior to the acquisition, the Company had an existing investment valued at $7.3 million in Northern Empire. The transaction was accounted for as an asset acquisition as Northern Empire did not have processes, including experienced personnel, in place to extract the minerals from the ground to produce outputs. As such, the total purchase price was allocated to the assets acquired and liabilities assumed based on their relative fair values. Total consideration and acquired assets and liabilities were as follows (in thousands except share data): Common shares issued (12,122,683 at $5.27) $ 63,887 Fair value of existing investment in Northern Empire 7,257 Transaction advisory fees and other acquisition costs 2,449 Total consideration 73,593 Total assets acquired 111,527 Total liabilities assumed 37,934 Net assets acquired $ 73,593 In October 2017, the Company completed the acquisition of JDS Silver Holdings Ltd. and its wholly-owned subsidiary JDS Silver Inc. (together, “JDS Silver”) which, following the closing of the acquisition, were amalgamated with a subsidiary of Coeur to form Coeur Silvertip Holdings Ltd., which owns the underground Silvertip silver-zinc-lead mine in northern British Columbia, Canada. JDS Silver was purchased for approximately $153.2 million in cash and $36.0 million in Coeur common stock. In addition, the Company recorded $47.7 million of contingent consideration payable in cash and common stock upon reaching future permitting and resource declaration milestones (see Note 21 -- Commitments and Contingencies), a portion of which was paid in 2019. The cash consideration was funded with $100.0 million of borrowing under the Facility (as defined in Note 12 -- Debt) and cash on hand. Upon closing, the Company issued approximately 4.2 million Coeur shares to former shareholders of JDS Silver Holdings Ltd. The transaction was accounted for as a business combination, which requires that assets acquired and liabilities assumed be recognized at their respective fair values at the acquisition date. The acquisition was not significant to the Company’s results of operations, individually or in the aggregate, because the Silvertip mine was in in pre-production. As there were no significant differences from the Company’s historical results of operations, no pro forma financial information was provided. The purchase price allocation is as follows (in thousands): Common shares issued (4,191,679 at $8.59) $ 36,007 Cash 153,194 Contingent consideration 47,705 Total purchase price (1) $ 236,906 Total assets acquired 328,450 Total liabilities assumed 91,544 Net assets acquired $ 236,906 (1) Purchase price has been adjusted for restricted cash acquired due to the adoption of ASU 2016-01.

The 2024 Senior Notes are governed by an Indenture dated as of May 31, 2017 (the “Indenture”), among the Company, as issuer, certain of the Company's subsidiaries named therein, as guarantors thereto (the “Guarantors”), and the Bank of New York Mellon, as trustee. In connection with the sale of the 2024 Senior Notes, the Company entered into a Registration Rights Agreement. On August 4, 2017, the Company commenced an exchange offer of registered 2024 Senior Notes for privately-placed 2024 Senior Notes which was completed on September 12, 2017. The 2024 Senior Notes bear interest at a rate of 5.875% per year from the date of issuance. Interest on the 2024 Senior Notes is payable semi-annually in arrears on June 1 and December 1 of each year, commencing on December 1, 2017. The 2024 Senior Notes will mature on June 1, 2024 and are fully and unconditionally guaranteed by the Guarantors. At any time prior to June 1, 2020, the Company may redeem all or part of the 2024 Senior Notes upon not less than 30 nor more than 60 days’ prior notice at a redemption price equal to the sum of (i) 100% of the principal amount thereof, plus (ii) a make-whole premium as of the date of redemption, plus (iii) accrued and unpaid interest and additional interest, if any, thereon, to the date of redemption. In addition, the Company may redeem some or all of the 2024 Senior Notes on or after June 1, 2020, at redemption prices set forth in the Indenture, together with accrued and unpaid interest. At any time prior to June 1, 2020, the Company may use the proceeds of certain equity offerings to redeem up to 35% of the aggregate principal amount of the 2024 Senior Notes, including any permitted additional 2024 Senior Notes, at a redemption price equal to 105.875% of the principal amount. The Indenture contains covenants that, among other things, limit the Company’s ability under certain circumstances to incur additional indebtedness, pay dividends or make other distributions or repurchase or redeem capital stock, prepay, redeem or repurchase certain debt, make loans and investments, create liens, sell, transfer or otherwise dispose of assets, enter into transactions with affiliates, enter into agreements restricting the Company's subsidiaries' ability to pay dividends and impose conditions on the Company’s ability to engage in mergers, consolidations and sales of all or substantially all of its assets. The Indenture also contains certain “Events of Default” (as defined in the Indenture) customary for indentures of this type. In the third quarter of 2019, the Company entered into multiple privately-negotiated agreements to exchange $20 million in aggregate principal amount of its 2024 Senior Notes for approximately 4.5 million shares of common stock. Based on the closing price of the Company’s common stock on the date of each exchange, the exchanges resulted in an aggregate loss of $1.3 million . Revolving Credit Facility In September 2017, the Company, as borrower, and certain subsidiaries of the Company, as guarantors, entered into the Credit Agreement with respect to the Company’s revolving credit facility (the “Facility”). The Facility originally had a term of four years. Loans under the Facility bear interest at a rate equal to either a base rate plus a margin ranging from 1.00% to 1.75% or an adjusted LIBOR rate plus a margin ranging from 2.00% to 2.75%, as selected by the Company, in each case, with such margin determined in accordance with a pricing grid based upon the Company’s consolidated net leverage ratio as of the end of the applicable period. In October 2018, the Company entered into an amendment to increase the Facility by $50.0 million from $200.0 million to $250.0 million and extend the term by approximately one year to October 2022. In April and August of 2019, the Company entered into amendments to the Credit Agreement to, among other items, modify the financial covenants to provide greater flexibility in 2019. The Facility is secured by substantially all of the assets of the Company and its domestic subsidiaries, including the land, mineral rights and infrastructure at the Kensington, Rochester and Wharf mines and Coeur Sterling, as well as a pledge of the shares of certain of the Company’s subsidiaries. The Credit Agreement contains representations and warranties and affirmative and negative covenants that are usual and customary, including representations, warranties, and covenants that, among other things, restrict the ability of the Company and its subsidiaries to incur additional debt, incur or permit liens on assets, make investments and acquisitions, consolidate or merge with any other company, engage in asset sales and make dividends and distributions. The Credit Agreement contains financial covenants consisting of a consolidated net leverage ratio and a consolidated interest coverage ratio. Obligations under the Credit Agreement may be accelerated upon the occurrence of certain customary events of default. At December 31, 2019 , the Company had all $250.0 million available under the Facility. At December 31, 2019 , the interest rate on the principal of the Facility was 4.2% . Silvertip Debt Obligation The Company assumed an existing third-party debt obligation as part of the Silvertip acquisition. In February 2018, the Company voluntarily terminated and repaid the remaining debt obligation of $ 12.6 million . 2021 Senior Notes Concurrent with the offering of the 2024 Senior Notes, the Company commenced a cash tender offer (the “Tender Offer”) to purchase the outstanding $178.0 million in aggregate principal amount of its 7.875% Senior Notes due 2021 (the “2021 Senior Notes”). The Tender Offer was made on the terms and subject to the conditions set forth in the Offer to Purchase dated May 19, 2017. Holders of the 2021 Senior Notes who tendered their notes were entitled to receive $1,043.88 per $1,000 principal amount of the Notes, plus accrued and unpaid interest. $118.1 million aggregate principal amount of the Notes were tendered and purchased by the Company on May 31, 2017. In accordance with the terms of the indenture governing the 2021 Senior Notes, the remaining $59.9 million aggregate principal amount of the Notes were redeemed on June 30, 2017 at the redemption price of $1,039.38 per $1,000 principal amount, plus accrued and unpaid interest. The Company recorded a loss of $9.3 million as a result of the extinguishment of the 2021 Senior Notes. Finance Lease Obligations From time to time, the Company acquires mining equipment and facilities under finance lease agreements. In the year ended December 31, 2019, the Company entered into new lease financing arrangements primarily for mining equipment at Silvertip and Rochester.

The Company analyzes its deferred tax assets and, if it is determined that the Company will not realize all or a portion of its deferred tax assets, it will record or increase a valuation allowance. Conversely, if it is determined that the Company will ultimately be more likely than not able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced. There are a number of factors that impact the Company’s ability to realize its deferred tax assets. For additional information, please see the section titled “Risk Factors” included in Item 1A. Based upon this analysis, the Company has recorded valuation allowances as follows: Year ended December 31, In thousands 2019 2018 U.S. $ 213,783 $ 223,444 Canada 118,738 7,661 Mexico 15,884 17,606 New Zealand 21,863 22,482 Other 1,009 1,646 $ 371,277 $ 272,839 The Company has the following tax attribute carryforwards at December 31, 2019, by jurisdiction: In thousands U.S. Canada Mexico New Zealand Other Total Regular net operating losses $ 421,561 $ 236,849 $ 52,947 $ 80,838 $ 2,344 $ 794,539 Expiration years 2020-2038 2029-2039 2020-2030 Indefinite 2020-2022 Capital losses 82,147 — — — — 82,147 Alternative minimum tax credits 430 — — — — 430 Foreign tax credits 24,939 — — — — 24,939 The majority of the U.S. capital losses will expire from 2020 through 2022. Alternative minimum tax credits do not expire and foreign tax credits expire if unused beginning in 2020. The utilization of U.S. net operating loss carryforwards, tax credit carryforwards, and recognized built-in losses may be subject to limitation under the rules regarding a change in stock ownership as determined by the Internal Revenue Code and state tax laws. Section 382 of the Internal Revenue Code of 1986, as amended, imposes annual limitations on the utilization of net operating loss carryforwards, tax credit carryforwards, and certain built-in losses upon an ownership change as defined under that Section. Generally, an ownership change may result from transactions that increase the aggregate ownership of certain shareholders in the Company’s stock by more than 50 percentage points over a three-year testing period. If the Company experiences an ownership change, an annual limitation would be imposed on certain of the Company’s tax attributes, including net operating losses and certain other losses, credits, deductions or tax basis. Management has determined that the Company experienced ownership changes during 2002, 2003, 2007, and 2015 for purposes of Section 382. Based on management’s calculations, the Company does not expect any of its U.S. tax attributes to expire unused as a result of the Section 382 annual limitations. However, the annual limitations may impact the timeframe over which the net operating loss carryforwards can be used, potentially impacting cash tax liabilities in a future period. The U.S. federal tax credits and state net operating losses may potentially be limited as well. We continue to maintain a full valuation allowance on our US net deferred tax assets since it is more likely than not that the related tax benefits will not be realized. The Company may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if the Company earns U.S. federal taxable income, it may be limited in the ability to (1) recognize current deductions on built-in loss assets and (2) offset this income with our pre-change net operating loss carryforwards and other tax credit carryforwards, which may be subject to limitations, potentially resulting in increased future tax liability to us. Under the new U.S. federal income tax law, federal net operating losses incurred in 2019 and in future years may be carried forward indefinitely, but the deductibility of such federal net operating losses is limited to 80% of future taxable income. The Company intends to indefinitely reinvest earnings from Mexican operations. A reconciliation of the beginning and ending amount related to unrecognized tax benefits is below (in thousands): Unrecognized tax benefits at December 31, 2017 $ 5,324 Gross increase to current period tax positions — Gross increase to prior period tax positions 37 Reductions in unrecognized tax benefits resulting from a lapse of the applicable statute of limitations (1,585 ) Unrecognized tax benefits at December 31, 2018 $ 3,776 Gross increase to current period tax positions — Gross increase to prior period tax positions 137 Reductions in unrecognized tax benefits resulting from a lapse of the applicable statute of limitations (1,207 ) Unrecognized tax benefits at December 31, 2019 $ 2,706 At December 31, 2019, 2018, and 2017, $2.7 million , $3.8 million , and $4.3 million , respectively, of these gross unrecognized benefits would, if recognized, decrease the Company’s effective tax rate. The Company operates in numerous countries around the world and is subject to, and pays annual income taxes under, the various income tax regimes in the countries in which it operates. The Company has historically filed, and continues to file, all required income tax returns and paid the taxes reasonably determined to be due. The tax rules and regulations in many countries are highly complex and subject to interpretation. From time to time, the Company is subject to a review of its historic income tax filings and, in connection with such reviews, disputes can arise with the taxing authorities over the interpretation or application of certain rules to the Company’s business conducted within the country involved. The Company files income tax returns in various U.S. federal and state jurisdictions, in all identified foreign jurisdictions, and various others. The statute of limitations remains open from 2016 for the US federal jurisdiction and from 2011 for certain other foreign jurisdictions. As a result of statutes of limitations that will begin to expire within the next 12 months in various jurisdictions and possible settlement of audit-related issues with taxing authorities in various jurisdictions with respect to which none of these issues are individually significant, the Company believes that it is reasonably possible that the total amount of its unrecognized income tax liability will decrease between $2.5 million and $0.0 million in the next 12 months. The Company classifies interest and penalties associated with uncertain tax positions as a component of income tax expense and recognized interest and penalties of $2.3 million , $3.5 million , and $4.8 million at December 31, 2019, 2018, and 2016, respectively.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company has stock incentive plans for executives and eligible employees. Stock awards include stock options, restricted stock, and performance shares. Stock-based compensation expense for the years ended December 31, 2019, 2018, and 2017 was $9.3 million , $8.3 million and $10.5 million , respectively. At December 31, 2019, there was $6.7 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.6 years . Restricted Stock Restricted stock granted under the Company’s incentive plans are accounted for based on the market value of the underlying shares on the date of grant and vest in equal installments annually over three years . Restricted stock awards are accounted for as equity awards. Holders of restricted stock are entitled to vote the shares and to receive any dividends declared on the shares. The following table summarizes restricted stock activity for the years ended December 31, 2019, 2018, and 2017: Restricted Stock Number of Shares Weighted Average Grant Date Fair Value Outstanding at December 31, 2016 2,433,915 4.48 Granted 799,165 8.78 Vested (1,023,708 ) 5.14 Canceled/Forfeited (53,527 ) 5.90 Outstanding at December 31, 2017 2,155,845 5.72 Granted 1,000,690 7.63 Vested (1,277,076 ) 5.30 Canceled/Forfeited (337,811 ) 6.51 Outstanding at December 31, 2018 1,541,648 7.14 Granted 1,586,590 4.90 Vested (797,025 ) 6.36 Canceled/Forfeited (146,538 ) 5.70 Outstanding at December 31, 2019 2,184,675 $ 5.89 At December 31, 2019, there was $3.8 million of unrecognized compensation cost related to restricted stock awards to be recognized over a weighted-average period of 1.4 years . Performance Shares Performance shares granted under the Company’s incentive plans are accounted for as equity awards at fair value using a Monte Carlo simulation valuation model. Performance shares granted during and subsequent to 2018 will vest at the end of a three-year service period if internal performance metrics are met, with the number of shares vesting impacted by the inclusion of a modifier based upon a relative stockholder return metric. The relative stockholder return metric is included in the determination of the grant date fair value of the performance shares however the recognition of compensation cost for performance share awards is based on the results of the internal performance metrics. Outstanding performance shares granted prior to 2018 will vest at the end of a three-year service period if relative stockholder return and internal performance metrics are met. The existence of a market condition requires recognition of compensation cost for the performance share awards over the requisite period regardless of whether the relative stockholder return metric is met. The following table summarizes performance shares activity for the years ended December 31, 2019, 2018, and 2017: Performance Shares Number of Shares Weighted Average Grant Date Fair Value Outstanding at December 31, 2016 2,372,632 4.53 Granted 316,213 11.58 Vested (66,696 ) 14.18 Canceled/Forfeited (253,868 ) 11.56 Outstanding at December 31, 2017 2,368,281 4.44 Granted (1) 869,421 7.41 Vested (1,086,058 ) 6.83 Canceled/Forfeited (613,329 ) 5.41 Outstanding at December 31, 2018 1,538,315 4.05 Granted (2) 946,000 4.71 Vested (969,903 ) 1.77 Canceled/Forfeited (2) (300,267 ) 1.84 Outstanding at December 31, 2019 1,214,145 6.93 (1) Includes 461,242 additional shares granted in connection with the vesting of the 2015 award in 2018 due to above-target performance in accordance with the terms of the awards. (2) Includes 207,264 additional shares granted and 300,267 shares cancelled in connection with the vesting of the 2016 award in 2019 due to above-target and below target performance, respectively, in accordance with the terms of the award. At December 31, 2019, there was $2.9 million of unrecognized compensation cost related to performance shares to be recognized over a weighted average period of 1.9 years . Stock Options and Stock Appreciation Rights Stock options and stock appreciation rights (SARs) granted under the Company’s incentive plans vest over three years and are exercisable over a period not to exceed ten years from the grant date. The exercise price of stock options is equal to the fair market value of the shares on the date of the grant. The value of each stock option award is estimated using the Black-Scholes option pricing model. Stock options are accounted for as equity awards and SARs are accounted for as liability awards and remeasured at each reporting date. SARs, when vested, provide the participant the right to receive cash equal to the excess of the market price of the shares over the exercise price when exercised. The following table sets forth the weighted average fair value of stock options and the assumptions used to estimate the fair value of the stock options using the Black-Scholes option valuation model: 2019 2018 2017 Weighted average fair value of stock options granted $ — $ 4.09 $ 3.91 Volatility — 66.86 % 67.07 % Expected life in years 0 4.00 4.00 Risk-free interest rate — 2.07 % 1.69 % Dividend yield — — — The following table summarizes stock option and SAR activity for the years ended December 31, 2019, 2018, and 2017: Stock Options SARs Shares Weighted Average Exercise Price Shares Weighted Outstanding at December 31, 2016 656,611 10.76 42,152 14.14 Granted 14,820 7.60 — — Exercised (26,966 ) 3.28 — — Canceled/forfeited (27,019 ) 21.88 — — Outstanding at December 31, 2017 617,446 10.53 42,152 14.14 Granted 14,310 7.91 — — Exercised (159,069 ) 3.35 — — Canceled/forfeited (153,601 ) 11.48 — — Outstanding at December 31, 2018 319,086 13.53 42,152 14.14 Exercised (11,055 ) 5.57 — — Canceled/forfeited (11,519 ) 9.31 — — Expired (4,733 ) 10.00 (9,870 ) 10.00 Outstanding at December 31, 2019 291,779 14.05 32,282 15.40 The following table summarizes outstanding stock options as of December 31, 2019.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Year ended December 31, In thousands 2019 2018 2017 Unrealized gain (loss) on equity securities $ 15,348 $ (5,019 ) $ — Realized gain (loss) on equity securities 860 7,964 — Zinc options — 753 — Interest rate swap, net (178 ) (60 ) — Other — — (864 ) Fair value adjustments, net $ 16,030 $ 3,638 $ (864 ) Accounting standards establish a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1), secondary priority to quoted prices in inactive markets or observable inputs (Level 2), and the lowest priority to unobservable inputs (Level 3). The following table presents the Company’s financial assets and liabilities measured at fair value on a recurring basis (at least annually) by level within the fair value hierarchy. Assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement: Fair Value at December 31, 2019 In thousands Total Level 1 Level 2 Level 3 Assets: Equity securities $ 35,646 $ 35,646 $ — $ — Other derivative instruments, net 753 — 753 — $ 36,399 $ 35,646 $ 753 $ — Liabilities: Silvertip contingent consideration $ 25,000 $ — $ — $ 25,000 Other derivative instruments, net 275 — 275 — $ 25,275 $ — $ 275 $ 25,000 Fair Value at December 31, 2018 In thousands Total Level 1 Level 2 Level 3 Assets: Equity and debt securities $ 17,806 $ 15,589 $ — $ 2,217 Other derivative instruments, net 914 — 914 — $ 18,720 $ 15,589 $ 914 $ 2,217 Liabilities: Silvertip contingent consideration $ 49,276 $ — $ — $ 49,276 Other derivative instruments, net 644 — 644 — $ 49,920 $ — $ 644 $ 49,276 The Company’s investments in equity securities are recorded at fair market value in the financial statements based primarily on quoted market prices. Such instruments are classified within Level 1 of the fair value hierarchy. Quoted market prices are not available for certain debt securities; these securities are valued using pricing models, which require the use of observable and unobservable inputs, and are classified within Level 3 of the fair value hierarchy. The Company’s other derivative instruments, net, include concentrate and certain doré sales contracts, gold and zinc hedges, and an interest rate swap which are valued using pricing models with inputs derived from observable market data, including contractual terms, forward market prices, yield curves, credit spreads, and other unobservable inputs. The model inputs can generally be verified and do not involve significant management judgment. Such instruments are classified within Level 2 of the fair value hierarchy. In July 2017, the Company sold the Endeavor Silver Stream and remaining non-core royalties to Metalla Royalty & Streaming Ltd. (“Metalla”) for total consideration of $13.0 million , including a $6.7 million convertible debenture. The convertible debenture bears interest at a rate of 5% payable semi-annually, and is convertible into Metalla shares in connection with future equity financings or asset acquisitions by Metalla at the then-current price to maintain the Company’s approximate 19.9% ownership of Metalla. During 2018, Metalla completed a number of equity-based transactions, triggering the top-up clause in the convertible debenture, resulting in the conversion of $4.4 million of debt into 7.4 million shares of Metalla common stock during 2018. The fair value of the convertible debenture is estimated based on observable and unobservable data including yield curves and credit spreads. Therefore, the Company classifies the convertible debenture in Level 3 of the fair value hierarchy. The convertible debenture was due to mature in June 30, 2027 , however, through a combination of principal repayments and conversions into Metalla shares, the convertible debenture was extinguished in February 2019. In October 2017, the Company acquired the Silvertip mine from shareholders of JDS Silver Holdings Ltd (the “Silvertip Acquisition”). The consideration for the Silvertip Acquisition includes two $25.0 million contingent payments, which were payable in cash and common stock upon reaching a future permitting milestone and resource declaration milestone, respectively. The fair value of the Silvertip contingent consideration is estimated based on an estimated discount rate of 2.5% for the contingent permitting payment and 2.9% for the contingent resource declaration payment and is classified within Level 3 of the fair value hierarchy. During 2019, the Company paid the $25.0 million due for the permitting milestone in the form of cash and common stock and, subsequent to the end of the period covered by this Report, the Company paid the $25.0 million due for the resource declaration milestone in the form of cash and common stock. No assets or liabilities were transferred between fair value levels in the year ended December 31, 2019. The following tables present the changes in the fair value of the Company's Level 3 financial assets and liabilities for the year ended December 31, 2019 and 2018: Year Ended December 31, 2019 In thousands Balance at the beginning of the period Revaluation Settlements Accretion Balance at the Liabilities: Silvertip contingent consideration $ 49,276 $ — $ (25,000 ) $ 724 $ 25,000 Year Ended December 31, 2018 In thousands Balance at the beginning of the period Revaluation Settlements Accretion Balance at the Assets: Equity and debt securities $ 6,891 $ (274 ) $ (4,400 ) $ — $ 2,217 Liabilities: Silvertip contingent consideration $ 47,965 $ — $ — $ 1,311 $ 49,276 During the fourth quarter of 2019, Coeur recorded an impairment of long-lived assets totaling $250.8 million . The fair values of long-lived assets were estimated using a discounted cash flow approach derived from live-of-mine plans which were developed using long-term pricing reflective of the current price environment and management’s projections for operating costs. The discounted cash flow model used significant unobservable inputs and is therefore classified within Level 3 for the fair value hierarchy. See Note 4 -- Impairment of Long-lived Assets for additional detail regarding the impairment. The following table sets forth the quantitative and qualitative information related to the unobservable inputs used in the calculation of the Company's non-recurring Level 3 fair value measurements: Description Valuation technique Unobservable input Range / Weighted Average Property, plant, and equipment, Mining properties and Right of Use Assets Discounted cash flow Discount rate 7.5% Long-term silver price per Oz $17.00 Long-term zinc price per pound $1.07 Long-term lead price per pound $0.93 The fair value of financial assets and liabilities carried at book value in the financial statements at December 31, 2019 and December 31, 2018 is presented in the following table: December 31, 2019 In thousands Book Value Fair Value Level 1 Level 2 Level 3 Liabilities: 2024 Senior Notes (1) $ 226,885 $ 228,585 $ — $ 228,585 $ — Revolving Credit Facility (2) $ — $ — $ — $ — $ — (1) Net of unamortized debt issuance costs of $3.1 million .

(2) Unamortized debt issuance costs of $2.2 million included in Other Non-Current Assets . The fair value of the Manquiri Notes Receivable (as defined in Note 22 -- Discontinued Operations) is estimated based on observable and unobservable data including yield curves and credit spreads, therefore, the Company classifies the Manquiri Notes Receivable in Level 3 of the fair value hierarchy; see Note 22 -- Discontinued Operations for additional detail. The fair value of the 2024 Senior Notes was estimated using quoted market prices. The fair value of the Revolving Credit Facility approximates book value as the liability is secured, has a variable interest rate, and lacks significant credit concerns.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS & HEDGING ACTIVITIES The Company is exposed to various market risks, including the effect of changes in metal prices and interest rates, and uses derivatives to manage financial exposures that occur in the normal course of business. The Company does not hold or issue derivatives for trading or speculative purposes. The Company may elect to designate certain derivatives as hedging instruments under U.S. GAAP. The Company formally documents all relationships between designated hedging instruments and hedged items as well as its risk management objectives and strategies for undertaking hedge transactions. This process includes linking all derivatives designated as hedges to either recognized assets or liabilities or forecasted transactions and assessing, both at inception and on an ongoing basis, the effectiveness of the hedging relationships. Derivatives Not Designated as Hedging Instruments Provisional Metal Sales The Company enters into sales contracts with third-party smelters, refiners and off-take customers which, in some cases, provide for a provisional payment based upon preliminary assays and quoted metal prices. The provisionally priced sales contracts contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable recorded at the forward price at the time of sale. The embedded derivatives do not qualify for hedge accounting and are marked to market through earnings each period until final settlement. Interest Rate Swap The Company enters into interest rate swap contracts in which it receives variable-rate interest and pays fixed-rate interest. The Company uses these instruments to manage its exposure to changes in interest rates related to the Facility (see Note 12-- Debt) and does not designate the instruments as hedges from an accounting standpoint and does not apply hedge accounting. The notional amount is used to measure interest to be paid or received. During the second quarter of 2019, an interest rate swap derivative instrument, with a notional amount of $50.0 million , expired and was replaced with an instrument with a notional amount of $75.0 million , which became effective in June 2019, covered a contractual term of six months and net settled monthly. The Company had no outstanding interest rate swap contracts at December 31, 2019 . At December 31, 2019 , the Company had the following derivative instruments that settle as follows: In thousands except average prices and notional ounces 2020 Thereafter Provisional silver sales contracts $ 8,116 $ — Average silver price per ounce $ 17.89 $ — Notional ounces 453,610 — Provisional gold sales contracts $ 16,265 $ — Average gold price per ounce $ 1,471 $ — Notional ounces 11,054 — Provisional zinc sales contracts $ 10,762 $ — Average zinc price per pound $ 1.03 $ — Notional pounds 10,411,742 — Provisional lead sales contracts $ 5,485 $ — Average lead price per pound $ 0.88 $ — Notional pounds 6,205,968 — The following summarizes the classification of the fair value of the derivative instruments: December 31, 2019 In thousands Prepaid expenses and other Accrued liabilities and other Provisional metal sales contracts $ 753 $ 275 December 31, 2018 In thousands Prepaid expenses and other Accrued liabilities and other Provisional metal sales contracts $ 784 $ 644 Zinc options 113 — Interest rate swaps 17 — $ 914 $ 644 The following represent mark-to-market gains (losses) on derivative instruments for the years ended December 31, 2019, 2018 and 2017 and 2018, respectively (in thousands): Year ended December 31, Financial statement line Derivative 2019 2018 2017 Revenue Provisional metal sales contracts $ 337 $ 111 $ 631 Fair value adjustments, net Zinc options — 753 — Fair value adjustments, net Interest rate swaps (178 ) (60 ) — $ 159 $ 804 $ 631 Derivatives Designated as Cash Flow Hedging Strategies To protect the Company’s exposure to fluctuations in metal prices, in the third quarter of 2019, the Company entered into Asian (or average value) put and call option contracts in net-zero-cost collar arrangements on a volume of 21,000 ounces of gold per month for the last 4 months of 2019 and 12,000 ounces of gold per month for the first 8 months of 2020. The contracts are net cash settled monthly and, if the price of gold at the time of expiration is between the put and call prices, would expire at no cost to the Company. The Company has elected to designate these instruments as cash flow hedges of forecasted transactions at their inception. At December 31, 2019 , the Company had the following derivative cash flow hedge instruments that settle as follows: In thousands except average prices and notional ounces 2020 Gold put options Average gold strike price per ounce $ 1,408 Notional ounces 96,000 Gold call options Average gold strike price per ounce $ 1,803 Notional ounces 96,000 The effective portions of cash flow hedges are recorded in accumulated other comprehensive income (loss) (“AOCI”) until the hedged item is recognized in earnings. Deferred gains and losses associated with cash flow hedges of metal sales revenue are recognized as a component of net sales in the same period as the related revenue is recognized. For options designated as cash flow hedges, the total change in cash flows value will be considered when assessing of hedge effectiveness. The Company has performed an assessment and determined that the terminal value of the hedging instrument and the forecasted transaction match and has qualitatively concluded that changes in the cash flows attributable to the variability of the total sales price of gold are expected to completely offset and the hedging relationship is considered perfectly effective. Future assessments are performed to verify that critical terms of the hedging instrument and the forecasted transaction continue to match, and the forecasted transactions remain probable, as well as an assessment of any adverse developments regarding the risk of the counterparties defaulting on their commitments. There have been no such changes in critical terms or adverse developments and the Company has concluded that there is no ineffectiveness to be recorded. Derivative instruments designated as cash flow hedges must be de-designated as hedges when it is probable the forecasted hedged transaction will not occur in the initially identified time period or within a subsequent two-month time period. Deferred gains and losses in AOCI associated with such derivative instruments would be reclassified into fair value adjustments, net in the period of de-designation. Any subsequent changes in fair value of such derivative instruments would be reflected in fair value adjustments, net unless they are re-designated as hedges of other transactions. As of December 31, 2019, the Company had $0.5 million of after-tax gains in AOCI related to gains from commodity cash flow hedge transactions. The Company does not expect to recognize any of these after-tax gains in its consolidated statement of comprehensive income during the next 12 months. Actual amounts ultimately reclassified to net income are dependent on the price of gold in effect when derivative contracts currently outstanding mature. The following summarizes the classification of the fair value of the derivative instruments designated as cash flow hedges: December 31, 2019 In thousands Prepaid expenses and other Accrued liabilities and other Gold zero cost collars $ — $ 136 The following table sets forth the pre-tax gains (losses) on derivatives designated as cash flow hedges that have been included in AOCI and the consolidated statement of comprehensive income for the years ended December 31, 2019 and 2018.

Earnings Per Share [Abstract]
NET INCOME (LOSS) PER SHARE	NET INCOME (LOSS) PER SHARE Basic net income (loss) per share is computed by dividing net income (loss) available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock. For the years ended December 31, 2019, 2018, and 2017, there were 1,137,726 , 1,312,737 and 653,354 common stock equivalents, respectively, related to equity-based awards were not included in the diluted earnings per share calculation as the shares would be antidilutive. Year ended December 31, In thousands except per share amounts 2019 2018 2017 Net income (loss) available to common stockholders: Income (loss) from continuing operations $ (346,896 ) $ (48,955 ) $ 10,925 Income (loss) from discontinued operations 5,693 550 (12,244 ) $ (341,203 ) $ (48,405 ) $ (1,319 ) Weighted average shares: Basic 218,812 188,606 180,096 Effect of stock-based compensation plans — — 4,048 Diluted 218,812 188,606 184,144 Basic income (loss) per share: Income (loss) from continuing operations $ (1.59 ) $ (0.26 ) $ 0.06 Income (loss) from discontinued operations 0.03 — (0.07 ) Basic (1) $ (1.56 ) $ (0.26 ) $ (0.01 ) Diluted income (loss) per share: Income (loss) from continuing operations $ (1.59 ) $ (0.26 ) $ 0.06 Income (loss) from discontinued operations 0.03 — (0.07 ) Diluted (1) $ (1.56 ) $ (0.26 ) $ (0.01 ) (1) Due to rounding, the sum of net income per share from continuing operations and discontinued operations may not equal net income per share. In June 2019, the Company completed a $50.0 million “at the market” offering of its common stock, par value $0.01 per share (the “First Offering”). The First Offering was conducted pursuant to an Equity Distribution Agreement, entered into in May 2019 between the Company and Citigroup Global Markets Inc. as the sales agent. The Company sold a total of 16,630,444 shares of its common stock at an average price of $3.00 per share, raising net proceeds (after sales commissions) of $48.9 million in the First Offering. Proceeds from the First Offering were used to repay outstanding amounts under the Facility. In September 2019, the Company completed a $75.0 million “at the market” offering of its common stock, par value $0.01 per share (the “Second Offering” and, together with the First Offering, referred to herein as the “Offerings”).

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Palmarejo Gold Stream Coeur Mexicana, S.A. de C.V. (“Coeur Mexicana”), a subsidiary of Coeur, sells 50% of Palmarejo gold production (excluding production from certain properties acquired in 2015) to a subsidiary of Franco-Nevada Corporation (“Franco-Nevada”) under a gold stream agreement for the lesser of $800 or spot price per ounce. In 2015, Coeur Mexicana received a $22.0 million deposit toward future deliveries under the gold stream agreement. In accordance with generally accepted accounting principles, although Coeur Mexicana has satisfied its contractual obligation to repay the deposit to Franco-Nevada, the deposit is accounted for as deferred revenue and is recognized as revenue on a units of production basis as ounces are sold to Franco-Nevada. At December 31, 2019 the remaining unamortized balance was $11.1 million , which is included in Accrued liabilities and other and Other long-term liabilities on the Consolidated Balance Sheet. Kensington Prepayment In June 2019, Coeur entered into a transaction with an existing metal sales counterparty whereby it amended its existing sales and purchase contract for gold concentrate from its Kensington mine (the “Amended Sales Contract”) to allow for a $25.0 million prepayment for deliveries of gold concentrate from the Kensington mine. The Amended Sales Contract also includes an option to allow for an additional $15.0 million prepayment for deliveries of gold concentrate, which Coeur exercised in December 2019. In 2019, the Kensington mine delivered approximately $25.0 million of gold concentrate to the counterparty. The remaining deliveries of $15.0 million are recognized as a deferred revenue liability and are presented in Accrued liabilities and other on the Consolidated Balance Sheet. Under the relevant terms of the Amended Sales Contract, Coeur maintains its exposure to the price of gold and expects to recognize the full value of the accrued liability by the June 2020. Silvertip Contingent Consideration A total of up to $50.0 million of contingent consideration, payable in cash and common stock, is payable in conjunction with the Silvertip Acquisition based upon the achievement of two milestones, one of which was achieved and paid during 2019 and the other of which the Company has determined to be probable at December 31, 2019 . The first milestone payment of $25.0 million was contingent upon receipt of a permit expansion for a sustained mining and milling rate of 1,000 tonnes per day (the “Permit contingent consideration”). The permit application was submitted to the British Columbia Ministry of Energy and Mining on April 30, 2018 and following its approval in November 2019, the Company provided a payment of $25.0 million in the form of $18.7 million in cash and 1.0 million shares of common stock to satisfy the Permit contingent consideration obligation. At December 31, 2019, based on the Silvertip mine’s total mineralized material (including reserves) (the “Resource contingent consideration”), the former JDS Silver Holdings Ltd. shareholders were entitled to the full second contingent payment of $25.0 million , which has been included in Accrued liabilities and other on the Consolidated Balance Sheet. Subsequent to the end of the period covered by this Report, the Company made a payment of $25.0 million in the form of $18.8 million in cash and 0.9 million shares of common stock to satisfy the Resource contingent consideration obligation. Mexico VAT Litigation Included in non-current receivables as of December 31, 2019 are $28.0 million due from the Mexican government associated with VAT that was paid under Coeur Mexicana’s prior royalty agreement with a subsidiary of Franco-Nevada Corporation, which was terminated effective in 2016. Under the royalty agreement, Coeur applied for and initially received VAT refunds associated with the royalty payments in the normal course; however, in 2011 the Mexican tax authorities began denying the Company’s VAT refunds based on the argument that VAT was not legally due on the royalty payments. Accordingly, Coeur began to request refunds of the VAT as undue payments, which the Mexican tax authorities also denied. The Company has since been engaged in ongoing efforts to recover the VAT from the Mexican government (including through litigation). Despite a favorable ruling from Mexican tax courts in this matter in 2018, litigation continues, some of which has been determined unfavorably to the Company in 2019 based on interpretations of applicable law and prior court decisions which the Company and its counsel believe are erroneous and which are now under appeal. While the Company believes that it remains legally entitled to be refunded the full amount of the VAT receivable, the Company may continue to experience delays or obstacles in the recovery of VAT and it is possible that some or all of the VAT receivable may not ultimately be recovered as outcomes in Mexican tax courts and the process for recovering funds even if there is a successful outcome in litigation can be unpredictable. Other Commitments and Contingencies As part of its ongoing business and operations, the Company and its affiliates are required to provide surety bonds, bank letters of credit and bank guarantees as financial support for various purposes, including environmental remediation, reclamation, and other general corporate purposes. As of December 31, 2019 and 2018, we had surety bonds totaling $215.6 million and $216.3 million , respectively in place as financial support for future reclamation and closure costs. The obligations associated with these instruments are generally related to performance requirements that the Company addresses through its ongoing operations. As the specific requirements are met, the beneficiary of the associated instrument cancels and/or returns the instrument to the issuing entity. Certain of these instruments are associated with operating sites with long-lived assets and will remain outstanding until closure. The Company believes it is in compliance with all applicable bonding obligations and will be able to satisfy future bonding requirements through existing or alternative means, as they arise.

Discontinued Operations and Disposal Groups [Abstract]
Assets and Liabilities Held For Sale	DISCONTINUED OPERATIONS In December 2017, the Company and certain of its subsidiaries entered into a definitive agreement (as amended, the “Manquiri Agreement”) to sell all of the outstanding capital stock of Empresa Minera Manquiri S.A. (“Manquiri”), which is the operator of the San Bartolomé mine and processing facility. On February 28, 2018, the Manquiri Divestiture was completed, and, in accordance with the Manquiri Agreement, the capital stock in Manquiri was sold to Ag-Mining Investments, AB, a privately-held Swedish company (the “Buyer”), in exchange for, among other items, (A) 2.0% net smelter returns royalty on all metals processed through the San Bartolomé mine’s processing facility (the “NSR”) and (B) promissory notes payable by the Buyer with an aggregate principal amount equal to $27.6 million (the “Manquiri Notes Receivable”). In September 2018, the Company entered into the Letter Agreement with the Buyer pursuant to which the total aggregate principal amount of the Manquiri Notes Receivable was reduced to $25.0 million, and the Buyer made a concurrent cash payment of $15.0 million to the Sellers in respect of the Manquiri Notes Receivable. In addition, the Company also agreed to suspend the quarterly payments in respect of the NSR until October 15, 2019 and to forgo any rights to any value added tax refunds collected or received by Manquiri. On February 28, 2019, the parties executed a letter agreement (the “February Letter Agreement”), which amended certain terms of the Manquiri Agreement. Pursuant to the February Letter Agreement, the Buyer agreed to accelerate repayment of the remaining aggregate $6.0 million owed under the Manquiri Notes Receivable, by making a concurrent cash payment of $2.0 million to the Company in respect of the Manquiri Notes Receivable and agreeing to pay the remaining $4.0 million outstanding principal amount in two equal installments on March 31, 2019 and April 30, 2019, both of which were received. As of the date of the entry into the February Letter Agreement, the remaining obligations under the Manquiri Agreement (including post-closing indemnification obligations) terminated. The Company recorded a $5.7 million gain on the sale Manquiri following the release of the indemnification liability (associated with termination of post-closing indemnification obligations) pursuant to the February Letter Agreement. In addition, pursuant to the February Letter Agreement, until October 31, 2019 (the “Option Period”) the Buyer had a non-exclusive option (the “Option”) to either purchase or terminate its obligations to pay the NSR, by making a payment to Coeur of $4.8 million (the “NSR Payment Amount”). During the Option Period, the Company’s right to receive NSR payments was suspended. Since the Buyer did not exercise the Option and pay the NSR Payment Amount to Coeur during the Option Period, the Buyer’s obligations to pay the NSR resumed for the quarterly period beginning on July 1, 2019 and ended September 30, 2019. Subsequent to the period covered by this Report, the Buyer purchased the NSR from the Company by making a payment to Coeur of $4.5 million. The sale of Manquiri and the San Bartolomé mine had a significant effect on the Company's results and operations. Accordingly, San Bartolomé’s operations for the years ended December 31, 2019, 2018 and 2017 are classified on the Consolidated Statements of Operations and Comprehensive Income (Loss) as Income (loss) from discontinued operations . The major classes of line items constituting the pretax profit or loss for the years ended December 31, 2019, 2018 and 2017, respectively. are as follows (in thousands): Year ended December 31, 2019 2018 2017 Revenue $ — $ 12,346 $ 73,065 COSTS AND EXPENSES Costs applicable to sales (1) — 12,269 74,074 Amortization — — 5,899 General and administrative — 41 172 Exploration — — 23 Write-downs — — 3,390 Pre-development, reclamation, and other — 265 4,664 OTHER INCOME (EXPENSE), NET Interest expense, net of capitalized interest — (3 ) (27 ) Other, net — (260 ) 1,763 Pretax profit (loss) on discontinued operations related to major classes of pretax profit (loss) — (492 ) (13,421 ) Pretax gain on the disposal of the discontinued operation 5,693 1,525 — Total pretax gain or loss on discontinued operations 5,693 1,033 (13,421 ) Income and mining tax (expense) benefit — (483 ) 1,177 Income (loss) from discontinued operations $ 5,693 $ 550 $ (12,244 ) (1) Excludes amortization.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Risks and Uncertainties [Policy Text Block]	Risks and uncertainties As a mining company, the revenue, profitability and future rate of growth of the Company are substantially dependent on the prevailing prices for gold, silver, zinc and lead. The prices of these metals are volatile and affected by many factors beyond the Company’s control, including prevailing interest rates and returns on other asset classes, expectations regarding inflation, speculation, currency values, governmental decisions regarding precious metals stockpiles, global and regional demand and production, political and economic conditions and other factors. A substantial or extended decline in commodity prices could have a material adverse effect on the Company’s financial position, results of operations, cash flows, access to capital and the quantities of reserves that the Company can economically produce. Further, the carrying value of the Company’s property, plant and equipment, net; mining properties, net; inventories and ore on leach pads are particularly sensitive to the outlook for commodity prices. A decline in the Company’s price outlook from current levels could result in material impairment charges related to these assets.
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The Company's Consolidated Financial Statements have been prepared in accordance with United States Generally Accepted Accounting Principles. The preparation of the Company's Consolidated Financial Statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements and reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to metal prices and mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of production amortization calculations, environmental, reclamation and closure obligations, estimates of recoverable silver and gold in leach pad inventories, estimates of fair value for certain reporting units and asset impairments, valuation allowances for deferred tax assets, and the fair value and accounting treatment of financial instruments, equity securities, asset acquisitions, the allocation of fair value to assets and liabilities assumed in connection with business combinations, and derivative instruments. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Accordingly, actual results will differ from the amounts estimated in these financial statements.
Consolidation, Policy [Policy Text Block]	Principles of Consolidation The Consolidated Financial Statements include the wholly-owned subsidiaries of the Company, the most significant of which are Coeur Mexicana S.A. de C.V., Coeur Rochester, Inc., Coeur Alaska, Inc., Wharf Resources (U.S.A.), Inc., Coeur Silvertip Holdings Ltd. All intercompany balances and transactions have been eliminated.
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents include all highly-liquid investments with an original maturity of three months or less. The Company minimizes its credit risk by investing its cash and cash equivalents with major U.S. and international banks and financial institutions located principally in the United States with a minimum credit rating of A1, as defined by Standard & Poor’s. The Company’s management believes that no concentration of credit risk exists with respect to the investment of its cash and cash equivalents. At certain times, amounts on deposit may exceed federal deposit insurance limits.
Receivables, Policy [Policy Text Block]	Receivables Trade receivables and other receivable balances are reported at outstanding principal amounts, net of an allowance for doubtful accounts, if deemed necessary. Management evaluates the collectability of receivable account balances to determine the allowance, if any. Management considers the other party's credit risk and financial condition, as well as current and projected economic and market conditions, in determining the amount of the allowance. Receivable balances are written off when management determines that the balance is uncollectible.
Ore on Leach Pad [Policy Text Block]	Ore on Leach Pads The heap leach process extracts silver and gold by placing ore on an impermeable pad and applying a diluted cyanide solution that dissolves a portion of the contained silver and gold, which are then recovered in metallurgical processes. The Company uses several integrated steps to scientifically measure the metal content of ore placed on the leach pads. As the ore body is drilled in preparation for the blasting process, samples are taken of the drill residue which are assayed to determine estimated quantities of contained metal. The Company estimates the quantity of ore by utilizing global positioning satellite survey techniques. The Company then processes the ore through crushing facilities where the output is again weighed and sampled for assaying. A metallurgical reconciliation with the data collected from the mining operation is completed with appropriate adjustments made to previous estimates. The crushed ore is then transported to the leach pad for application of the leaching solution. As the leach solution is collected from the leach pads, it is continuously sampled for assaying. The quantity of leach solution is measured by flow meters throughout the leaching and precipitation process. After precipitation, the product is converted to doré at the Rochester mine and a form of gold concentrate at the Wharf mine, representing the final product produced by each mine. The inventory is stated at lower of cost or net realizable value, with cost being determined using a weighted average cost method. The historical cost of metal expected to be extracted within twelve months is classified as current and the historical cost of metals contained within the broken ore expected to be extracted beyond twelve months is classified as non-current. Ore on leach pads is valued based on actual production costs incurred to produce and place ore on the leach pad, less costs allocated to minerals recovered through the leach process. The estimate of both the ultimate recovery expected over time and the quantity of metal that may be extracted relative to the time the leach process occurs requires the use of estimates, which are inherently inaccurate due to the nature of the leaching process. The quantities of metal contained in the ore are based upon actual weights and assay analysis. The rate at which the leach process extracts gold and silver from the crushed ore is based upon laboratory testing and actual experience of more than twenty years of leach pad operations at the Rochester mine and thirty years of leach pad operations at the Wharf mine. The assumptions used by the Company to measure metal content during each stage of the inventory conversion process includes estimated recovery rates based on laboratory testing and assaying. The Company periodically reviews its estimates compared to actual experience and revises its estimates when appropriate. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted for on a prospective basis.
Metal and Other Inventory [Policy Text Block]	Metal and Other Inventory Inventories include concentrate, doré, and operating materials and supplies. The classification of inventory is determined by the stage at which the ore is in the production process. All inventories are stated at the lower of cost or net realizable value, with cost being determined using a weighted average cost method. Concentrate and doré inventory includes product at the mine site and product held by refineries. Metal inventory costs include direct labor, materials, depreciation, depletion and amortization as well as overhead costs relating to mining activities.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant, and Equipment Expenditures for new facilities, assets acquired pursuant to capital leases, new assets or expenditures that extend the useful lives of existing facilities are capitalized and depreciated using the straight-line method at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such facilities, lease term, or the useful life of the individual assets. Productive lives range from 7 to 30 years for buildings and improvements and 3 to 10 years for machinery and equipment. Certain mining equipment is depreciated using the units-of-production method based upon estimated total proven and probable reserves.
Operational Mining Properties and Mine [Policy Text Block]	Mining Properties and Mine Development Capitalization of mine development costs begins once all operating permits have been secured, mineralization is classified as proven and probable reserves and a final feasibility study has been completed. Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Costs incurred before mineralization are classified as proven and probable reserves are capitalized if a project is in pre-production phase or expensed and classified as Exploration or Pre-development if the project is not yet in pre-production. Mine development costs are amortized using the units of production method over the estimated life of the ore body generally based on recoverable ounces to be mined from proven and probable reserves. Interest expense allocable to the cost of developing mining properties and to construct new facilities is capitalized until assets are ready for their intended use. Drilling and related costs incurred at the Company’s operating mines are expensed as incurred in Exploration, unless the Company can conclude with a high degree of confidence, prior to the commencement of a drilling program, that the drilling costs will result in the conversion of a mineralized material into proven and probable reserves. The Company’s assessment is based on the following factors: results from previous drill programs; results from geological models; results from a mine scoping study confirming economic viability of the resource; and preliminary estimates of mine inventory, ore grade, cash flow and mine life. In addition, the Company must have all permitting and/or contractual requirements necessary to have the right to and/or control of the future benefit from the targeted ore body. The costs of a drilling program that meet these criteria are capitalized as mine development costs. Drilling and related costs of approximately $7.5 million and $18.6 million at December 31, 2019 and 2018, respectively, were capitalized. The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Costs applicable to sales in the same period as the revenue from the sale of inventory.
Mineral Interests [Policy Text Block]	Mineral Interests Significant payments related to the acquisition of land and mineral rights are capitalized. Prior to acquiring such land or mineral rights, the Company generally makes a preliminary evaluation to determine that the property has significant potential to develop an economic ore body. The time between initial acquisition and full evaluation of a property’s potential is variable and is determined by many factors including: location relative to existing infrastructure, the property’s stage of development, geological controls and metal prices. If a mineable ore body is discovered, such costs are amortized when production begins using the units of- production method based on recoverable ounces to be mined from proven and probable reserves. If no mineable ore body is discovered, such costs are expensed in the period in which it is determined the property has no future economic value.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	Impairment of Long-lived Assets We review and evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Asset impairment is considered to exist if the total estimated undiscounted pretax future cash flows are less than the carrying amount of the asset. In estimating future cash flows, assets are grouped at the lowest level for which there is identifiable cash flows that are largely independent of future cash flows from other asset groups. An impairment loss is measured by discounted estimated future cash flows, and recorded by reducing the asset's carrying amount to fair value. Future cash flows are estimated based on estimated quantities of recoverable minerals, expected gold, silver, lead and zinc prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans. Existing proven and probable reserves and value beyond proven and probable reserves, including mineralization other than proven and probable reserves are included when determining the fair value of mine site asset groups at acquisition and, subsequently, in determining whether the assets are impaired. The term “recoverable minerals” refers to the estimated amount of gold, silver, lead and zinc that will be obtained after taking into account losses during ore processing and treatment. Estimates of recoverable minerals from exploration stage mineral interests are risk adjusted based on management’s relative confidence in such materials. The ability to achieve the estimated quantities of recoverable minerals from exploration stage mineral interests involves further risks in addition to those risk 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 could ultimately be mined economically. Assets classified as exploration potential have the highest level of risk that the carrying value of the asset can be ultimately realized, due to the still lower level of geological confidence and economic modeling. During the fourth quarter of 2019, the Company performed a comprehensive analysis of its Silvertip property and determined that indicators of impairment existed, primarily as a result of continued deterioration in zinc and lead market conditions as well as ongoing challenges related to the processing facility. As a result of the impairment indicators, a recoverability test was performed and the Company concluded that the long-lived assets for the Silvertip property was impaired. A non-cash impairment charge of $250.8 million was recorded during the fourth quarter of 2019. The write-down was allocated between Property, plant and equipment, net , Mining properties, net and Other non-current assets , in the amounts of $43.6 million , $201.5 million and $5.7 million , respectively. See Note 4 -- Impairment of Long-lived Assets and 16 -- Fair Value Measurements for additional detail of the impairment and assumptions used in the determination of the fair value of the long-lived assets tested for impairment.
Mining Properties Held for Sale [Policy Text Block]	Properties Held for Sale In determining whether to classify a property as held for sale, the Company considers whether: (i) management has committed to a plan to sell the property; (ii) the investment is available for immediate sale, in its present condition; (iii) the Company has initiated a program to locate a buyer; (iv) the Company believes that the sale of the property is probable; (v) the Company has received a significant non-refundable deposit for the purchase of the property; (vi) the Company is actively marketing the property for sale at a price that is reasonable in relation to its estimated fair value; and (vii) actions required for the Company to complete the plan indicate that it is unlikely that any significant changes will be made to the plan. If all of the above criteria are met, the Company classifies the property as held for sale. When these criteria are met, the Company suspends depreciation on the properties held for sale. The properties held for sale and associated liabilities are classified separately on the consolidated balance sheets. Such properties are recorded at the lesser of the carrying value or estimated fair value less costs to sell. Additionally, if the sale represents a strategic shift that has (or will have) a major effect on the entity's results and operations, the assets, liabilities and operations for the periods presented are classified on the Consolidated Balance Sheets as held for sale and Consolidated Statements of Comprehensive Income (Loss) as discontinued operations for all periods presented.
Restricted Assets Policy [Policy Text Block]	Restricted Assets The Company, under the terms of its self-insurance and bonding agreements with certain banks, lending institutions and regulatory agencies, is required to collateralize certain portions of its obligations. The Company has collateralized these obligations by assigning certificates of deposit that have maturity dates ranging from three months to a year, to the respective institutions or agencies. At December 31, 2019 and 2018, the Company held certificates of deposit and cash under these agreements of $8.8 million and $12.3 million , respectively. The ultimate timing of the release of the collateralized amounts is dependent on the timing and closure of each mine and repayment of the facility. In order to release the collateral, the Company must seek approval from certain government agencies responsible for monitoring the mine closure status. Collateral could also be released to the extent the Company is able to secure alternative financial assurance satisfactory to the regulatory agencies. The Company believes there is a reasonable probability that the collateral will remain in place beyond a twelve-month period and has therefore classified these investments as long-term.
Lessee, Leases [Policy Text Block]	Leases We determine if an arrangement is, or contains, a lease at the inception date. Operating leases are included in Other assets, non-current with the related liabilities included in Accrued liabilities and Other and Other long-term liabilities . Assets under finance leases, which primarily represent property and equipment , are included in Property, plant and equipment, net , with the related liabilities included in debt, current and debt, non-current on the Consolidated Balance Sheet. Operating lease assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. We use our estimated incremental borrowing rate in determining the present value of lease payments. Variable components of the lease payments such as maintenance costs are expensed as incurred and not included in determining the present value. Our lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. We have lease agreements with lease and non-lease components which are accounted for as a single lease component.
Asset Retirement Obligation [Policy Text Block]	Reclamation The Company recognizes obligations for the expected future retirement of tangible long-lived assets and other associated asset retirement costs. The fair value of a liability for an asset retirement obligation will be recognized in the period in which it is incurred if a reasonable estimate of fair value can be made. The fair value of the liability is added to the carrying amount of the associated asset and this additional carrying amount is depreciated over the life of the asset. An accretion cost, representing the increase over time in the present value of the liability, is recorded each period in Pre-development, reclamation, and other . As reclamation work is performed or liabilities are otherwise settled, the recorded amount of the liability is reduced. Future remediation costs for inactive mines are accrued based on management’s best estimate at the end of each period of the discounted costs expected to be incurred at the site. Such cost estimates include, where applicable, ongoing care and maintenance and monitoring costs. Changes in estimates are reflected prospectively in the period an estimate is revised.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency The assets and liabilities of the Company’s foreign subsidiaries are measured using U.S. dollars as their functional currency. Revenues and expenses are remeasured at the average exchange rate for the period. Foreign currency gains and losses are included in the determination of net income or loss.
Derivatives, Policy [Policy Text Block]	Derivative Financial Instruments The Company is exposed to various market risks, including the effect of changes in metal prices and interest rates, and uses derivatives to manage financial exposures that occur in the normal course of business. The Company may elect to designate certain derivatives as hedging instruments under U.S. GAAP. The Company, from time to time, uses derivative contracts to protect the Company’s exposure to fluctuations in metal prices. The Company has elected to designate these instruments as cash flow hedges of forecasted transactions at their inception. Assuming normal market conditions, the change in the market value of such derivative contracts has historically been, and is expected to continue to be, highly effective at offsetting changes in price movements of the hedged item. For derivatives not designated as hedging instruments, the Company recognizes derivatives as either assets or liabilities on the balance sheet and measures those instruments at fair value. Changes in the value of derivative instruments not designated as hedging instruments are recorded each period in the Consolidated Statement of Comprehensive Income (Loss) in Fair value adjustments, net or Revenue . Management applies judgment in estimating the fair value of instruments that are highly sensitive to assumptions regarding commodity prices, market volatilities, and foreign currency exchange rates. See Note 17 -- Derivative Financial Instruments and Hedging Activities for additional information.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	Stock-based Compensation The Company estimates the fair value of stock options using the Black-Scholes option pricing model and stock appreciation rights (“SARs”) awards using market comparison. Stock options granted are accounted for as equity-based awards and SARs are accounted for as liability-based awards. The value of the SARs is remeasured at each reporting date. The Company estimates forfeitures of stock-based awards based on historical data and periodically adjusts the forfeiture rate. The adjustment of the forfeiture rate is recorded as a cumulative adjustment in the period the forfeiture estimate is changed. Compensation costs related to stock based compensation are included in General and administrative expenses , Costs applicable to sales , and Property, plant, and equipment, net as deemed appropriate. The fair value of restricted stock is based on the Company's stock price on the date of grant. The fair value of performance leverage stock units (“PSUs”) with market conditions is determined using a Monte Carlo simulation model. Stock based compensation expense related to awards with a market or performance condition is generally recognized over the vesting period of the award utilizing the graded vesting method, while all other awards are recognized on a straight-line basis. The Company's estimates may be impacted by certain variables including, but not limited to, stock price volatility, employee stock option exercise behaviors, additional stock option grants, estimates of forfeitures, the Company's performance, and related tax impacts.
Income Tax, Policy [Policy Text Block]	Income and Mining Taxes The Company uses an asset and liability approach which results in the recognition of deferred tax liabilities and assets for the expected future tax consequences or benefits of temporary differences between the financial reporting basis and the tax basis of assets and liabilities, as well as operating loss and tax credit carryforwards, using enacted tax rates in effect in the years in which the differences are expected to reverse. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of its deferred tax assets will not be realized. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in making this assessment. A valuation allowance has been provided for the portion of the Company’s net deferred tax assets for which it is more likely than not that they will not be realized.
Revenue Recognition, Policy	Revenue Recognition The Company produces doré and concentrate that is shipped to third-party refiners and smelters, respectively, for processing. The Company enters into contracts to sell its metal to various third-party customers which may include the refiners and smelters that process the doré and concentrate. The Company’s performance obligation in these transactions is generally the transfer of metal to the customer. In the case of doré shipments, the Company generally sells refined metal at market prices agreed upon by both parties. The Company also has the right, but not the obligation, to sell a portion of the anticipated refined metal in advance of being fully refined. When the Company sells refined metal or advanced metal, the performance obligation is satisfied when the metal is delivered to the customer. Revenue and Costs Applicable to Sales are recorded on a gross basis under these contracts at the time the performance obligation is satisfied. Under the Company’s concentrate sales contracts with third-party smelters, metal prices are set on a specified future quotational period, typically one to three months, after the shipment date based on market prices. When the Company sells gold concentrate to the third-party smelters, the performance obligation is satisfied when the concentrate is loaded onto the third-party shipping vessel. The contracts, in general, provide for provisional payment based upon provisional assays and historical metal prices. Final settlement is based on the applicable price for the specified future quotational period and generally occurs three to six months after shipment. The Company’s provisionally priced sales contain an embedded derivative that is required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale of concentrates measured at the forward price at the time of sale. The embedded derivative does not qualify for hedge accounting and is adjusted to fair value through revenue each period until the date of final metal settlement. The Company also sells concentrate under off-take agreements to third-party customers that are responsible for arranging the smelting of the concentrate. Prices can be either be fixed or based on a quotational period. The quotational period varies by contract, but is generally a one-month period following the shipment of the concentrate. The performance obligation is satisfied when the concentrate is loaded onto the third-party shipping vessel. The off-take agreement allows for the Company to sell concentrate in advance of shipment and results in the customer taking ownership of the concentrate prior to shipment. The Company recognizes revenue from concentrate sales, net of treatment and refining charges, when it satisfies the performance obligation of transferring control of the concentrate to the customer. For doré and off-take sales, the Company may incur a finance charge related to advance sales that is not considered significant and, as such, is not considered a separate performance obligation. In addition, the Company has elected to treat freight costs as a fulfillment cost under ASC 606 and not as a separate performance obligation. The Company’s gold stream agreement with a subsidiary of Franco-Nevada Corporation (“Franco-Nevada”) provided for a $20.0 million deposit paid by Franco-Nevada in exchange for the right and obligation, commencing in 2016, to purchase 50% of a portion of Palmarejo gold production at the lesser of $800 or market price per ounce. Because there is no minimum obligation associated with the deposit, it is not considered financing, and each shipment is considered to be a separate performance obligation. The streaming agreement represents a contract liability under ASC 606, which requires the Company to ratably recognize a portion of the deposit as revenue for each gold ounce delivered to Franco-Nevada. The following table presents a rollforward of the Franco-Nevada contract liability balance: Year ended December 31, In thousands 2019 2018 2017 Opening Balance $ 12,918 $ 14,883 $ 19,281 Revenue Recognized (1,857 ) (1,965 ) (4,398 ) Closing Balance $ 11,061 $ 12,918 $ 14,883 In December 2019, the Company received a $15.0 million prepayment for deliveries of gold concentrate from the Kensington mine pursuant to the Amended Sales Contract (as defined below). The Company expects to recognize the full value of the accrued liability by June 2020 when it satisfies the performance obligation of transferring control of the concentrate to the customer. See Note 21 -- Commitments and Contingencies for additional detail.
Recent Accounting Standards	Recently Adopted Accounting Standards In February 2016, the FASB issued ASU 2016-02, “ Leases, ” which required lessees to recognize assets and liabilities for the rights and obligations created by most leases on the balance sheet. These changes became effective for the Company’s fiscal year beginning January 1, 2019 and the Company adopted it using the cumulative-effect adjustment transition method approved by the FASB in July 2018, which did not require the Company to recast the comparative periods presented when transitioning to the new guidance on January 1, 2019. The Company elected to utilize the transition related practical expedients permitted by the new standard. In addition to existing capital leases and other financing obligations, the adoption of the new standard resulted in the recognition of additional right-of-use assets and lease liabilities related to operating leases of approximately $65.0 million . These changes did not materially impact the Company’s consolidated net income, financial position or cash flows. Recently Issued Accounting Standards In June 2016, the FASB issued ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326)”. The new standard is effective for reporting periods beginning after December 15, 2019. The standard replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires the use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. The standard requires a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We plan to adopt the new credit loss standard effective January 1, 2020. We do not expect the new credit loss standard to have a material effect on our financial position, results of operations or cash flows. In December 2019, the FASB issued ASU 2019-12, “Income Taxes - Simplifying the Accounting for Income Taxes (Topic 740)” which is intended to simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. ASU 2019-12 will be effective for interim and annual periods beginning after December 15, 2020 (January 1, 2021 for the Company). Early adoption is permitted. The Company is currently evaluating the impact the adoption of ASU 2019-12 will have on its consolidated financial statements.
