Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to materially impact the Company’s consolidated statement of cash flows. 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to materially impact the Company’s consolidated net income, financial position or cash flows. In March 2016, the FASB issued ASU 2016-09, “ Improvements to Employee Share-Based Payment Accounting, ” which amends several aspects of the accounting for share-based payment transaction, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. These changes became effective for the Company’s fiscal year beginning January 1, 2017, and the Company’s adoption had no impact on the Company’s consolidated financial position, results of operations, and 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. Modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, is required with an option to use certain transition relief. 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 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to 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. 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company has substantially completed its analysis of the new standard and reviewed potential impacts from timing of when control is transferred to customers, variable consideration on concentrate sales and classification of refining fees. The Company does not expect this ASU to materially impact the Company’s consolidated net income, financial position or cash flows.

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 decreased income and mining tax expense by $1.4 million and increased by $7.2 million for the three and nine months ended September 30, 2017, predominately due to the Mexican Peso. Also, favorable operating results at Palmarejo contributed to higher income and mining tax expense. The three and nine months ended September 30, 2016 benefited from a legal entity reorganization to integrate acquisitions that resulted in a valuation allowance release of $40.8 million and a $15.0 million deferred tax benefit related to unremitted earnings. 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 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 sections titled “Risk Factors” set forth in the 2016 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 2013 forward for the U.S. federal jurisdiction and from 2009 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, 2017 and December 31, 2016, the Company had $17.5 million and $19.6 million of total gross unrecognized tax benefits, respectively. If recognized, these unrecognized tax benefits 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, 2017 and December 31, 2016, the amount of accrued income-tax-related interest and penalties was $8.7 million and $8.7 million , respectively.

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, 2017 , 633,391 and 851,254 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, 215,298 and 404,543 common stock equivalents were excluded from the diluted earnings per share calculation for the three and nine months ended September 30, 2016 , respectively. The 3.25% Convertible Senior Notes (“Convertible Notes”) were not included in the computation of diluted net income (loss) per share for the three and nine months ended September 30, 2016 because there is no excess value upon conversion over the principal amount of the Convertible Notes. The outstanding Convertible Notes were redeemed in the third quarter of 2016.

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, 2017 In thousands Total Level 1 Level 2 Level 3 Assets: Equity and debt securities $ 29,125 $ 22,194 $ — $ 6,931 Other derivative instruments, net 44 — 44 — $ 29,169 $ 22,194 $ 44 $ 6,931 Liabilities: Other derivative instruments, net $ 255 $ — $ 255 $ — Fair Value at December 31, 2016 In thousands Total Level 1 Level 2 Level 3 Assets: Equity securities $ 4,488 $ 4,209 $ — $ 279 $ 4,488 $ 4,209 $ — $ 279 Liabilities: Rochester royalty obligation 9,287 — — 9,287 Other derivative instruments, net 762 — 762 — $ 10,049 $ — $ 762 $ 9,287 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 and equity 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, relate to concentrate and certain doré sales contracts valued using pricing models, which require inputs that are 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 May 2017, the Company repurchased the Rochester royalty obligation for $5.0 million , resulting in a pre-tax gain of $2.3 million , which is included in Other, net . The fair value of the Rochester royalty obligation was estimated based on observable market data including contractual terms, forward silver and gold prices, yield curves, and credit spreads, as well as the Company’s current mine plan which is considered a significant unobservable input. Therefore, the Company historically classified this obligation as a Level 3 financial liability. 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. The fair value of the convertible debenture is estimated based on observable market data including yield curves and credit spreads. Therefore, the Company classifies the convertible debenture in Level 3 of the fair value hierarchy. No assets or liabilities were transferred between fair value levels in the nine months ended September 30, 2017 . The following tables present the changes in the fair value of the Company's Level 3 financial assets and liabilities for the nine months ended September 30, 2017 : Three Months Ended September 30, 2017 In thousands Balance at the beginning of the period Additions Revaluation Settlements Balance at the end of the period Assets: Equity and debt securities $ 258 $ 6,677 $ (4 ) $ — $ 6,931 Nine Months Ended September 30, 2017 In thousands Balance at the beginning of the period Additions Revaluation Settlements Gain on settlement Balance at the end of the period Assets: Equity and debt securities $ 279 $ 6,677 $ (25 ) $ — $ — $ 6,931 Liabilities: Rochester royalty obligation $ 9,287 — $ 864 $ (7,819 ) (2,332 ) $ — The fair value of financial assets and liabilities carried at book value in the financial statements at September 30, 2017 and December 31, 2016 is presented in the following table: September 30, 2017 In thousands Book Value Fair Value Level 1 Level 2 Level 3 Liabilities: 5.875% Senior Notes due 2024 (1) $ 244,934 $ 247,161 $ — $ 247,161 $ — (1) Net of unamortized debt issuance costs of $5.1 million .

The fair value of the 5.875% Senior Notes due 2024 (the “2024 Senior Notes”) and the 7.875% Senior Notes due 2021 (the “2021 Senior Notes”) were estimated using quoted market prices.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	DERIVATIVE FINANCIAL INSTRUMENTS Palmarejo Gold Production Royalty In January 2009, the Company's subsidiary, Coeur Mexicana, S.A. de C.V. (“Coeur Mexicana”), entered into a gold production royalty agreement with a subsidiary of Franco-Nevada Corporation that covered 50% of the life of mine production from the Palmarejo mine and legacy adjacent properties. The royalty transaction included a minimum obligation of 4,167 gold ounces per month and terminated upon delivery of 400,000 gold ounces, which occurred in July 2016. The price volatility associated with the minimum royalty obligation was considered an embedded derivative. The Company was required to recognize the change in fair value of the remaining minimum obligation due to changing gold prices. For the three and nine months ended September 30, 2016, the mark-to-market adjustment associated with the change were losses of $0.1 million and $5.9 million , respectively. Payments on the royalty obligation decreased the carrying amount of the minimum obligation and the derivative liability. For the three and nine months ended September 30, 2016, realized losses on settlement of the liabilities were $0.1 million and $5.9 million , respectively. The mark-to-market adjustments and realized losses are included in Fair value adjustments, net . Provisional Silver and Gold 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. Changes in silver and gold prices resulted in provisional pricing mark-to-market losses of $0.1 million and gains of $0.6 million in the three and nine months ended September 30, 2017 , respectively, compared to losses of $0.8 million and gains of $0.4 million in the three and nine months ended September 30, 2016 , respectively. At September 30, 2017 , the Company had the following provisionally priced sales that settle as follows: In thousands except average prices and notional ounces 2017 Thereafter Provisional silver sales contracts $ 3,915 $ — Average silver price $ 16.86 $ — Notional ounces 232,200 — Provisional gold sales contracts $ 33,887 $ — Average gold price $ 1,299 $ — Notional ounces 26,087 — Silver and Gold Options During the nine months ended September 30, 2016, the Company had realized losses of $1.6 million , from settled option contracts.

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.

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, 2017 and December 31, 2016, the Company held certificates of deposit and cash under these agreements of $ 21.0 million and $17.6 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.

The Credit Agreement provides for a $200.0 million senior secured revolving credit facility (the “Facility”), which may be increased by up to $50.0 million in incremental loans and commitments subject to the terms of the Credit Agreement.

Loans under the Facility will 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. 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, 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.

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Labor Union Contract The Company maintains a labor agreement with Sindicato de Trabajadores Mineros de la Empresa Manquiri S.A. at the San Bartolomé mine in Bolivia. The San Bartolomé mine labor agreement, which became effective January 28, 2010, is currently active and does not have a fixed term. At September 30, 2017 , approximately 11% of the Company’s global labor force was covered by this collective bargaining agreement. The Company cannot predict whether this agreement will be renewed on similar terms or at all, whether future labor disruptions will occur or, if disruptions do occur, how long they will last.

Subsequent Events	SUBSEQUENT EVENTS On September 10, 2017, the Company entered into an Arrangement Agreement (the “Arrangement Agreement”) among the Company, an indirect wholly-owned subsidiary of the Company, JDS Silver Holdings, Ltd. (“JDS Silver”) and Silvertip Resources Investment LLC as representative of the shareholders of JDS Silver. The Arrangement Agreement provides for the implementation of a Plan of Arrangement (the “Plan of Arrangement”), pursuant to which the Company would acquire all of the issued and outstanding common shares of JDS Silver (the “Acquisition”), the owner of the high-grade silver-zinc-lead Silvertip Mine located in northern British Columbia, Canada. On October 16, 2017, the Supreme Court of British Columbia approved the Plan of Arrangement, and the Company completed the Acquisition on October 17, 2017. Total initial consideration for the Acquisition was $200.0 million , consisting of (i) payments by the Company of approximately $147.5 million in cash and approximately $37.5 million in shares of common stock of the Company, and (ii) the assumption of approximately $15.0 million in existing debt. Additional contingent consideration of up to $50.0 million may become payable upon the achievement of certain permitting and exploration milestones prior to December 31, 2019. In connection with the completion of the Acquisition, on October 12, 2017 the Company borrowed $100.0 million under the revolving credit facility.

Accounting Policies [Abstract]
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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to materially impact the Company’s consolidated statement of cash flows. 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to materially impact the Company’s consolidated net income, financial position or cash flows. In March 2016, the FASB issued ASU 2016-09, “ Improvements to Employee Share-Based Payment Accounting, ” which amends several aspects of the accounting for share-based payment transaction, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. These changes became effective for the Company’s fiscal year beginning January 1, 2017, and the Company’s adoption had no impact on the Company’s consolidated financial position, results of operations, and 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. Modified retrospective adoption for all leases existing at, or entered into after, the date of initial application, is required with an option to use certain transition relief. 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 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company is currently evaluating this standard and does not expect this ASU to 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. 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 become effective for the Company’s fiscal year beginning January 1, 2018. The Company has substantially completed its analysis of the new standard and reviewed potential impacts from timing of when control is transferred to customers, variable consideration on concentrate sales and classification of refining fees. The Company does not expect this ASU to materially impact the Company’s consolidated net income, financial position or cash flows.
