Summary Of Significant Accounti

Summary Of Significant Accounting Policies	9 Months Ended

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Revenue Recognition On January 1, 2018, the Company adopted the updated revenue guidance applicable under ASC 606, - “ Revenue from Contracts with Customers ”. The new guidance creates a five-step framework to determine revenue recognition: 1. Identify the contract with the customer 2. Identify the performance obligations 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations 5. Recognize revenue when (or as) the entity satisfies a performance obligation 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: Three months ended September 30, Nine months ended September 30, In thousands 2018 2017 2018 2017 Opening Balance $ 13,799 $ 16,835 $ 14,883 $ 19,281 Revenue Recognized (582 ) $ (793 ) $ (1,666 ) $ (3,239 ) Closing Balance $ 13,217 $ 16,042 $ 13,217 $ 16,042 Recent Accounting Standards In January 2017, the FASB issued ASU 2017-01, “ Business Combinations (Topic 805) - Clarifying the Definition of a Business, ” which clarifies the definition of a business to assist entities in the evaluation of acquisitions and disposals of assets or businesses. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows. In November 2016, the FASB issued ASU 2016-18, “ Statement of Cash Flows (Topic 230) - Restricted Cash, ” which will require entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and resulted in the inclusion of restricted cash equivalents on the Consolidated Statements of Cash Flows of $12.5 million and $11.4 million at September 30, 2018 and 2017, respectively. In August 2016, the FASB issued ASU 2016-15, “ Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments, ” which provides guidance on presentation and classification of certain cash receipts and payments in the statement of cash flows. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows. In February 2016, the FASB issued ASU 2016-02, “ Leases, ” which will require lessees to recognize assets and liabilities for the rights and obligations created by most leases on the balance sheet. These changes become effective for the Company’s fiscal year beginning January 1, 2019 and the Company plans to adopt it using the cumulative-effect adjustment transition method approved by the FASB in July 2018. The Company is currently evaluating the potential impact of implementing these changes on the Company’s consolidated financial position, results of operations, and cash flows. In January 2016, the FASB issued ASU 2016-01, “ Recognition and Measurement of Financial Assets and Financial Liabilities, ” which requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. This new guidance also updates certain disclosure requirements for these investments. These changes became effective for the Company’s fiscal year beginning January 1, 2018, and resulted in a reclassification of $2.6 million of unrealized holding gains and losses and deferred income taxes related to investments in equity securities from Accumulated other comprehensive income (loss) to Accumulated deficit in the Consolidated Balance Sheets on that date. Unrealized holding gains and losses related to investments in equity securities are now recognized in Fair value adjustments, net in the Consolidated Statements of Comprehensive Income (Loss). In July 2015, the FASB issued ASU 2015-11, “ Simplifying the Measurement of Inventory, ” which provides a revised, simpler measurement for inventory to be measured at the lower of cost and net realizable value. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows. In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers ” , which has subsequently been amended several times, to update revenue guidance under the newly-created ASC 606. The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. These changes became effective under the modified retrospective method of adoption for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows.

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, which was acquired in the fourth quarter of 2017, all operating segments are engaged in the discovery, mining, and production of gold and/or silver. Silvertip is engaged in the discovery, mining, and production of silver, zinc and lead. Silvertip commenced commercial production on September 1, 2018. Other includes the 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.

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 performance shares, restricted stock and stock options. Stock-based compensation expense for the three and nine months ended September 30, 2018 was $2.0 million and $6.6 million , respectively, compared to $2.6 million and $8.1 million for the three and nine months ended September 30, 2017 , respectively. At September 30, 2018 , there was $8.6 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.5 years. The performance shares issued in 2018 vest at the end of a three-year service period if internal performance metrics are met. The number of shares that vest is also impacted by the inclusion of a modifier that is 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. The performance shares issued prior to 2018 vest at the end of a three-year service period if relative stockholder return and internal performance metrics are met and the existence of a market condition requires recognition of compensation cost for the relative stockholder return portion of the performance share awards over the requisite period regardless of whether the relative stockholder return metric is met. All other stock-based compensation awards are consistent with prior years. The following table summarizes the grants awarded during the nine months ended September 30, 2018 : Grant date Restricted stock Grant date fair value of restricted stock Stock options Grant date fair value of stock options Performance shares Grant date fair value of performance shares March 5, 2018 31,887 $ 7.84 — $ — — $ — May 9, 2018 868,134 $ 7.90 14,310 $ 4.09 408,179 $ 7.39 The following options and stock appreciation rights were exercisable during the nine months ended September 30, 2018 : Award Type Number of Exercised Units Weighted Average Exercised Price Number of Exercisable Units Weighted Average Stock options 159,069 $ 3.35 315,032 $ 15.06 Stock appreciation rights — $ — 42,152 $ 14.14

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 three and nine months ended September 30, 2018 , 672,399 and 1,526,109 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. Similarly, 633,391 and 851,254 common stock equivalents were excluded from the diluted earnings per share calculation for the three and nine months ended September 30, 2017 , respectively. Three months ended September 30, Nine months ended September 30, In thousands except per share amounts 2018 2017 2018 2017 Net income (loss) available to common stockholders: Income (loss) from continuing operations $ (53,044 ) $ (11,728 ) $ (49,423 ) $ (3,424 ) Income (loss) from discontinued operations — (4,924 ) 550 (5,520 ) $ (53,044 ) $ (16,652 ) $ (48,873 ) $ (8,944 ) Weighted average shares: Basic 185,246 179,278 184,935 179,141 Effect of stock-based compensation plans — — — — Diluted 185,246 179,278 184,935 179,141 Basic income (loss) per share: Income (loss) from continuing operations $ (0.29 ) $ (0.07 ) $ (0.27 ) $ (0.02 ) Income (loss) from discontinued operations 0.00 (0.03 ) 0.00 (0.03 ) Basic (1) $ (0.29 ) $ (0.09 ) $ (0.26 ) $ (0.05 ) Diluted income (loss) per share: Income (loss) from continuing operations $ (0.29 ) $ (0.07 ) $ (0.27 ) $ (0.02 ) Income (loss) from discontinued operations 0.00 (0.03 ) 0.00 (0.03 ) Diluted (1) $ (0.29 ) $ (0.09 ) $ (0.26 ) $ (0.05 ) (1) Due to rounding, the sum of net income per share from continuing operations and discontinued operations may not equal net income per share.

INCOME AND MINING TAXES	INCOME AND MINING TAXES The following table summarizes the components of Income and mining tax (expense) benefit for the three and nine months ended September 30, 2018 and 2017 by significant jurisdiction: Three months ended September 30, Nine months ended September 30, 2018 2017 2018 2017 In thousands Income (loss) before tax Tax (expense) benefit Income (loss) before tax Tax (expense) benefit Income (loss) before tax Tax (expense) benefit Income (loss) before tax Tax (expense) benefit United States $ (35,250 ) $ (908 ) $ (6,055 ) $ (2,892 ) $ (45,397 ) $ (2,700 ) $ 8,036 $ (4,072 ) Argentina (2,058 ) (75 ) 738 (366 ) (1,985 ) (172 ) 281 1,704 Canada (13,194 ) 4,432 — — (17,103 ) 6,476 — — Mexico 1,419 (7,234 ) 3,210 (9,057 ) 35,088 (23,055 ) 9,665 (23,745 ) Other jurisdictions (176 ) — 4,668 (1,974 ) (575 ) — 2,634 2,073 $ (49,259 ) $ (3,785 ) $ 2,561 $ (14,289 ) $ (29,972 ) $ (19,451 ) $ 20,616 $ (24,040 ) The Company’s effective income and mining tax rate is a function of the combined effective tax rates and foreign exchange rates in the jurisdictions in which it operates. Variations in the jurisdictional mix of income and loss and foreign exchange rates result in significant fluctuations in the consolidated effective tax rate, along with mining taxes, uncertain tax positions, and a full valuation allowance on deferred tax assets related to losses in the United States and certain foreign jurisdictions. Fluctuations in foreign exchange rates on deferred tax balances increased income and mining tax expense by $3.0 million and decreased income and mining tax expense by $1.4 million for the three months ended September 30, 2018 and 2017, respectively. Fluctuations in foreign exchange rates on deferred tax balances increased income and mining tax expense by $2.1 million and $7.2 million for the nine months ended September 30, 2018 and 2017, respectively. The impact of foreign exchange rates on deferred tax balances is predominately due to the Mexican Peso and Canadian Dollar. A valuation allowance is provided for deferred tax assets for which it is more likely than not that the related tax benefits will not be realized. 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 ultimately will 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” in the 2017 10-K. The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various state and foreign jurisdictions. The statute of limitations remains open from 2015 forward for the U.S. federal jurisdiction and from 2011 forward for certain other foreign jurisdictions. As a result of statutes of limitation that will begin to expire within the next twelve months in various jurisdictions and possible settlements of audit-related issues with taxing authorities in various jurisdictions with respect to which none of the issues are individually significant, the Company believes that it is reasonably possible that the total amount of its net unrecognized income tax benefits will decrease between $1.5 million and $2.5 million in the next twelve months. At September 30, 2018 and December 31, 2017, the Company had $3.7 million and $4.3 million of total gross unrecognized tax benefits, respectively that, if recognized, would positively impact the Company’s effective income tax rate. The Company’s continuing practice is to recognize potential interest and/or penalties related to unrecognized tax benefits as part of its income tax expense. At September 30, 2018 and December 31, 2017, the amount of accrued income-tax-related interest and penalties was $3.5 million and $4.8 million , respectively.

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 September 30, 2018 In thousands Total Level 1 Level 2 Level 3 Assets: Equity and debt securities $ 24,232 $ 19,665 $ — $ 4,567 Other derivative instruments, net 507 — 507 — $ 24,739 $ 19,665 $ 507 $ 4,567 Liabilities: Silvertip contingent consideration $ 48,945 $ — $ — $ 48,945 Other derivative instruments, net 267 — 267 — $ 49,212 $ — $ 267 $ 48,945 Fair Value at December 31, 2017 In thousands Total Level 1 Level 2 Level 3 Assets: Equity and debt securities $ 34,837 $ 27,946 $ — $ 6,891 Other derivative instruments, net 251 — 251 — $ 35,088 $ 27,946 $ 251 $ 6,891 Liabilities: Silvertip contingent consideration $ 47,965 $ — $ — $ 47,965 Other derivative instruments, net 222 — 222 — $ 48,187 $ — $ 222 $ 47,965 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, 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 matures June 30, 2027 , 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. In July 2018, Metalla completed an asset acquisition through the issuance of additional common stock, triggering the top-up clause in the convertible debenture, resulting in the conversion of $1.9 million of debt into Metalla common stock. 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. In October 2017, the Company acquired the Silvertip mine from shareholders of JDS Silver Holdings Ltd. The consideration for the Silvertip mine includes two $25.0 million contingent payments, which are 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. No assets or liabilities were transferred between fair value levels in the nine months ended September 30, 2018. The following tables present the changes in the fair value of the Company's Level 3 financial assets and liabilities for the three and nine months ended September 30, 2018 : Three Months Ended September 30, 2018 In thousands Balance at the beginning of the period Revaluation Settlements Accretion Balance at the Assets: Equity and debt securities $ 6,227 $ 193 $ (1,853 ) $ — $ 4,567 Liabilities: Silvertip contingent consideration $ 48,616 $ — $ — $ 329 $ 48,945 Nine Months Ended September 30, 2018 In thousands Balance at the beginning of the period Revaluation Settlements Accretion Balance at the end of the period Assets: Equity and debt securities $ 6,891 $ (172 ) $ (2,152 ) $ — $ 4,567 Liabilities: Silvertip contingent consideration $ 47,965 $ — $ — $ 980 $ 48,945 The fair value of financial assets and liabilities carried at book value in the financial statements at September 30, 2018 and December 31, 2017 is presented in the following table: September 30, 2018 In thousands Book Value Fair Value Level 1 Level 2 Level 3 Assets: Manquiri Notes Receivable $ 9,207 $ 9,207 $ — $ — $ 9,207 Liabilities: 5.875% Senior Notes due 2024 (1) $ 245,662 $ 235,725 $ — $ 235,725 $ — Revolving Credit Facility (2) $ 120,000 $ 120,000 $ — $ 120,000 $ — (1) Net of unamortized debt issuance costs of $4.3 million .

In September 2018, the Company entered into a Letter Agreement with the Buyer, pursuant to which the total aggregate principal amount of the Manquiri Notes Receivable received as partial consideration in the Manquiri Divestiture was reduced from $28.5 million to $25.0 million , and the Buyer made a concurrent cash payment of $15.0 million to the Company in respect of the Manquiri Notes Receivable. In addition, the Company also agreed to suspend the quarterly payments in respect of the NSR on all metals processed through the San Bartolomé mine’s processing facility received as partial consideration in the Manquiri Divestiture until October 15, 2019 and to forgo any rights the Company retained in the transaction to any VAT refunds collected or received by Manquiri. Based on the Company’s evaluation of the terms of the Letter Agreement, the Company recorded an $18.6 million write-down that is made up of $13.1 million on the VAT refunds, $3.6 million on the Manquiri Notes Receivable and $1.9 million on the NSR, which is included in Other, net .. The fair value of the Manquiri Notes Receivable was determined using a discounted cash flow model using a 12% discount rate which takes into consideration the increased credit risk and short duration of the Manquiri Notes Receivable. The fair value 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 21 -- Discontinued Operations for additional detail. The fair value of the 5.875% Senior Notes due 2024 (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 Provisional Metal Sales The Company enters into sales contracts with third-party smelters and refiners 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. Zinc Options At September 30, 2018 , the Company has outstanding Asian (or average value) put and call option contracts in net-zero-cost collar arrangements on a volume of 300 metric tons of zinc per month commencing in April 2018 and ending in December 2018. The weighted average strike prices on the put and call contracts are $3,000 and $4,050 per metric ton, respectively. The contracts are generally net cash settled and, if the price of zinc at the time of the expiration is between the put and call prices, would expire at no cost to the Company. Interest Rate Swap The Company is a party to an interest rate swap contract in which it will receive variable-rate interest and pay fixed-rate interest. The Company uses this instrument to manage its exposure to changes in interest rates related to its Revolving Credit Facility (see Note 18 -- Debt). The interest rate swap derivative instrument is not designated as a hedge from an accounting standpoint and hedge accounting is not applied. The notional amount is used to measure interest to be paid or received. The interest rate swap derivative instrument became effective June 2018 with a contractual term of twelve months and net settles monthly. At September 30, 2018 , the Company had the following derivative instruments that settle as follows: In thousands except average prices and notional ounces 2018 Thereafter Provisional silver sales contracts $ 1,444 $ — Average silver price per ounce $ 14.61 $ — Notional ounces 98,832 — Provisional gold sales contracts $ 14,802 $ — Average gold price per ounce $ 1,224 $ — Notional ounces 12,089 — Provisional zinc sales contracts $ 2,123 $ — Average zinc price per pound $ 1.20 $ — Notional pounds 1,772,075 — Provisional lead sales contracts $ 1,130 $ — Average lead price per pound $ 0.92 $ — Notional pound 1,230,193 — Zinc put options purchased $ 2,700 $ — Average zinc strike price per metric ton $ 3,000 $ — Notional metric tons 900 — Zinc call options sold $ (3,645 ) $ — Average zinc strike price per metric ton $ 4,050 $ — Notional metric tons 900 — Fixed interest rate swap payable $ 960 $ — Fixed Interest rate 2.46 % — Notional dollars $ 50,000 $ — Variable interest rate swap receivable $ 979 $ — Average variable interest rate 2.51 % $ — Notional dollars $ 50,000 $ — The following summarizes the classification of the fair value of the derivative instruments: September 30, 2018 In thousands Prepaid expenses and other Accrued liabilities and other Provisional metal sales contracts $ 310 $ 267 Zinc options 339 — Interest rate swaps 68 — $ 717 $ 267 December 31, 2017 In thousands Prepaid expenses and other Accrued liabilities and other Provisional metal sales contracts $ 251 $ 222 The following represent mark-to-market gains (losses) on derivative instruments for the three and nine months ended September 30, 2018 and 2017, respectively (in thousands): Three months ended September 30, Nine months ended September 30, Financial statement line Derivative 2018 2017 2018 2017 Revenue Provisional metal sales contracts $ 34 $ 147 $ 15 $ 596 Fair value adjustments, net Zinc options 225 — 588 — Fair value adjustments, net Interest rate swaps 206 — 18 — $ 465 $ 147 $ 621 $ 596 Credit Risk The credit risk exposure related to any derivative instrument is limited to the unrealized gains, if any, on outstanding contracts based on current market prices. To reduce counter-party credit exposure, the Company enters into contracts with institutions management deems credit-worthy and limits credit exposure to each institution. The Company does not anticipate non-performance by any of its counterparties.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS 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. The cash consideration was funded with $100.0 million of borrowing under the Facility (as defined in Note 18 -- 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 acquisition aligns with the Company’s strategic shift to a North America-focused mining portfolio. 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 allocation of purchase price to the acquired assets and liabilities assumed is preliminary as of September 30, 2018 and subsequent adjustments may result in changes to mineral interest and other carrying amounts initially assigned based on the preliminary fair value analysis. The principal remaining items to be valued are property, plant and equipment and mining properties, which will be finalized within one year of the acquisition date and recorded in the fourth quarter of 2018, as management completes the review of the valuation methodologies used to estimate the fair value of these assets. The preliminary 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 Assets: Receivables and other assets $ 6,828 Property, plant, and equipment 29,943 Mining properties, net 288,464 325,235 Liabilities: Accounts payable and accrued liabilities 13,077 Asset retirement obligation 6,982 Debt and capital lease 20,149 Deferred income taxes 48,121 88,329 Net assets acquired $ 236,906 (1) Purchase price has been adjusted for restricted cash acquired due to the adoption of ASU 2016-01.

The Company has collateralized these obligations by assigning certificates of deposit that have maturity dates ranging from three months to a year to the applicable institutions or agencies. At September 30, 2018 and December 31, 2017, the Company held certificates of deposit and cash equivalents under these agreements of $21.4 million and $20.8 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 obligation. 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 the collateral will remain in place beyond a twelve-month period and has therefore classified these investments as long-term.

Pursuant to the terms of the agreement, the Company received, among other consideration, the NSR. Coeur estimates the value of this net smelter returns royalty to be approximately $7.1 million , which is included in Other. In September 2018, the Company entered into the Letter Agreement, pursuant to which the Company agreed to suspend the quarterly payments in respect of the NSR until October 15, 2019. Based on the Company’s evaluation of the terms of the Letter Agreement, the Company recorded a write-down of $1.9 million on the NSR. See Note 10 -- Fair Value Measurements and 21 -- Discontinued Operations for additional detail. The Silvertip mine reached commercial production on September 1, 2018. The determination of commercial production (or ready for intended use) was based on many factors requiring the exercise of judgment. Factors that were considered when determining if intended use had been achieved included achievement of continuous production or other output, mineral recoveries at or near expected levels, the absence of routine take-downs of the plant to address commissioning issues and fix problems, and the release of the commissioning team. Prior to commercial production, costs related to mine development, construction of long-lived assets, and inventory were capitalized; all other costs were expensed in the period incurred. Amortization of mining properties commenced when the mine reached commercial production.

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 the Paramount properties acquired in 2015) to 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 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. As of September 30, 2018, the remaining unamortized balance was $13.2 million . 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 October 2017 Silvertip acquisition. The contingent consideration is based on the achievement of two milestones, which the Company has determined to be probable at September 30, 2018. The first milestone payment of $25.0 million is contingent upon receipt of a permit expansion for a sustained mining and milling rate of 1,000 tonnes per day. The permit application was required to be submitted to the British Columbia Ministry of Energy and Mining no later than June 2018 and was submitted on April 30, 2018. The second milestone payment of up to $25.0 million is contingent upon the amount of resource tonnes added as of December 31, 2019. The former JDS Silver Holdings Ltd. shareholders will receive $5.0 million for a total resource of at least 2.5 million tonnes and $5.0 million for every 0.3 million tonnes over 2.5 million tonnes, up to 3.7 million tonnes. The maximum payment of $25.0 million can be earned if the total resource reaches 3.7 million tonnes. The Silvertip mine had total mineralized material of approximately 2.6 million tonnes at December 31, 2017.

Discontinued Operations and Disposal Groups [Abstract]
Assets and Liabilities Held For Sale	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 Manquiri, which is the operator of the San Bartolomé mine and processing facility (the “Manquiri Divestiture”). On February 28, 2018, the Manquiri Divestiture was completed, and, in accordance with the Agreement, Manquiri was sold to Ag-Mining Investments, AB, a privately-held Swedish company. See below for a discussion of the Letter Agreement, which amended certain terms of the Manquiri Agreement. Coeur and its subsidiaries received the following consideration: • The NSR commencing immediately upon the closing of the Transaction, valued at $7.1 million . • Pre-closing VAT refunds valued at $12.7 million that will be collected or received by Manquiri in the future will be paid to Coeur (net of collection costs). • The Manquiri Notes Receivable valued at $26.9 million payable to Coeur and certain of its subsidiaries representing Manquiri’s cash and cash equivalents on the date of closing of the Manquiri Divestiture, and providing for repayment beginning in October 2018. • The Company recognized a liability of approximately $5.7 million for certain post-closing covenants, guaranties and indemnification obligations on the part of the Company pursuant to the Agreement The sale of Manquiri resulted in a gain of $1.5 million , which is included in Income (loss) from discontinued operations . The sale of Manquiri and San Bartolomé had a significant effect on the Company's results and operations. Accordingly, San Bartolomé’s operations for the three and nine months ended September 30, 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 three and nine months ended September 30, 2018 and 2017 are as follows (in thousands): Three months ended September 30, Nine months ended September 30, 2018 2017 2018 2017 Revenue $ — $ 16,043 $ 12,346 $ 60,441 COSTS AND EXPENSES Costs applicable to sales (1) — 17,365 12,269 58,979 Amortization — 1,430 — 5,053 General and administrative — 67 41 92 Exploration — 23 — 23 Pre-development, reclamation, and other — 2,931 265 3,956 OTHER INCOME (EXPENSE), NET Interest expense, net of capitalized interest — (11 ) (3 ) (23 ) Other, net — 804 (260 ) 1,305 Pretax profit (loss) on discontinued operations related to major classes of pretax profit (loss) — (4,980 ) (492 ) (6,380 ) Pretax gain on the disposal of the discontinued operation — — 1,525 — Total pretax gain or loss on discontinued operations — (4,980 ) 1,033 (6,380 ) Income and mining tax (expense) benefit — 56 (483 ) 860 Income (loss) from discontinued operations $ — $ (4,924 ) $ 550 $ (5,520 ) (1) Excludes amortization. Net cash used by operating activities was $7.9 million for the three months ended September 30, 2017. Net cash used in operating activities from San Bartolomé was $2.7 million for the nine months ended September 30, 2018 compared to net cash provided by operating activities of $8.6 million for the nine months ended September 30, 2017, respectively. Net cash used in investing activities from San Bartolomé was $0.4 million for the three months ended September 30, 2017. Net cash used in investing activities from San Bartolomé were $28.5 million and $1.2 million for the nine months ended September 30, 2018 and 2017, respectively. In September 2018, the Company entered into a 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 on all metals processed through the San Bartolomé mine’s processing facility until October 15, 2019 and to forgo any rights to any value added tax refunds collected or received by Manquiri. Based on the Company’s evaluation of the terms of the Letter Agreement, the Company recorded an $18.6 million write-down that is made up of $13.1 million on the value added tax refunds, $3.6 million on the Manquiri Notes Receivable and $1.9 million on the NSR, which is included in Other, net .

Subsequent Events	SUBSEQUENT EVENTS On October 1, 2018 the Company completed its acquisition of Northern Empire Resources Corp. (“Northern Empire”). 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 $63.9 million as of the closing date. Prior to the acquisition, the Company had an existing investment valued at $4.5 million in Northern Empire. See Note 13 -- Investments for additional detail. On October 15, 2018 the Company entered into an Asset Purchase Agreement among the Company, Coeur Rochester, Inc.

Accounting Policies [Abstract]
Revenue Recognition, Policy	Revenue Recognition On January 1, 2018, the Company adopted the updated revenue guidance applicable under ASC 606, - “ Revenue from Contracts with Customers ”. The new guidance creates a five-step framework to determine revenue recognition: 1. Identify the contract with the customer 2. Identify the performance obligations 3. Determine the transaction price 4. Allocate the transaction price to the performance obligations 5. Recognize revenue when (or as) the entity satisfies a performance obligation 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: Three months ended September 30, Nine months ended September 30, In thousands 2018 2017 2018 2017 Opening Balance $ 13,799 $ 16,835 $ 14,883 $ 19,281 Revenue Recognized (582 ) $ (793 ) $ (1,666 ) $ (3,239 ) Closing Balance $ 13,217 $ 16,042 $ 13,217 $ 16,042
Recent Accounting Standards	Recent Accounting Standards In January 2017, the FASB issued ASU 2017-01, “ Business Combinations (Topic 805) - Clarifying the Definition of a Business, ” which clarifies the definition of a business to assist entities in the evaluation of acquisitions and disposals of assets or businesses. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows. In November 2016, the FASB issued ASU 2016-18, “ Statement of Cash Flows (Topic 230) - Restricted Cash, ” which will require entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and resulted in the inclusion of restricted cash equivalents on the Consolidated Statements of Cash Flows of $12.5 million and $11.4 million at September 30, 2018 and 2017, respectively. In August 2016, the FASB issued ASU 2016-15, “ Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash Payments, ” which provides guidance on presentation and classification of certain cash receipts and payments in the statement of cash flows. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows. In February 2016, the FASB issued ASU 2016-02, “ Leases, ” which will require lessees to recognize assets and liabilities for the rights and obligations created by most leases on the balance sheet. These changes become effective for the Company’s fiscal year beginning January 1, 2019 and the Company plans to adopt it using the cumulative-effect adjustment transition method approved by the FASB in July 2018. The Company is currently evaluating the potential impact of implementing these changes on the Company’s consolidated financial position, results of operations, and cash flows. In January 2016, the FASB issued ASU 2016-01, “ Recognition and Measurement of Financial Assets and Financial Liabilities, ” which requires entities to measure equity investments that do not result in consolidation and are not accounted for under the equity method at fair value and recognize any changes in fair value in net income. This new guidance also updates certain disclosure requirements for these investments. These changes became effective for the Company’s fiscal year beginning January 1, 2018, and resulted in a reclassification of $2.6 million of unrealized holding gains and losses and deferred income taxes related to investments in equity securities from Accumulated other comprehensive income (loss) to Accumulated deficit in the Consolidated Balance Sheets on that date. Unrealized holding gains and losses related to investments in equity securities are now recognized in Fair value adjustments, net in the Consolidated Statements of Comprehensive Income (Loss). In July 2015, the FASB issued ASU 2015-11, “ Simplifying the Measurement of Inventory, ” which provides a revised, simpler measurement for inventory to be measured at the lower of cost and net realizable value. These changes became effective for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows. In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers ” , which has subsequently been amended several times, to update revenue guidance under the newly-created ASC 606. The new standard provides a five-step approach to be applied to all contracts with customers and also requires expanded disclosures about revenue recognition. These changes became effective under the modified retrospective method of adoption for the Company’s fiscal year beginning January 1, 2018 and did not materially impact the Company’s consolidated net income, financial position or cash flows.

Capitalization of Internal Costs, Policy [Policy Text Block]	The determination of commercial production (or ready for intended use) was based on many factors requiring the exercise of judgment. Factors that were considered when determining if intended use had been achieved included achievement of continuous production or other output, mineral recoveries at or near expected levels, the absence of routine take-downs of the plant to address commissioning issues and fix problems, and the release of the commissioning team. Prior to commercial production, costs related to mine development, construction of long-lived assets, and inventory were capitalized; all other costs were expensed in the period incurred. Amortization of mining properties commenced when the mine reached commercial production.
