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, lead and zinc. The prices of these metals are volatile and affected by many factors beyond the Company’s control, and there can be no assurance that commodity prices will not be subject to wide fluctuations in the future. 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. The carrying value of the Company’s Mineral properties, plant and equipment ; Inventories ; Deferred income tax assets ; and Goodwill are sensitive to the outlook for commodity prices. A decline in the Company’s price outlook could result in material impairment charges related to these assets. In addition, the Company maintains cash balances at banking institutions in various jurisdictions which may or may not have deposit insurance. The Company mitigates potential cash risk by maintaining bank accounts with credit-worthy financial institutions. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company's financial condition, results of operations, and cash flows. Basis of Presentation The Condensed Consolidated Financial Statements have been prepared in accordance with the instructions to Form 10-Q and do not include all information and disclosures required by generally accepted accounting principles in the United States. Therefore, this information should be read in conjunction with SSR Mining Inc.’s Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022 filed on February 22, 2023, as amended on Form 10-K/A filed on March 17, 2023, solely to correct a typographical error related to the date of the audit opinion (together, “Form 10-K”). The information furnished herein reflects all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods reported. All such adjustments are, in the opinion of management, of a normal recurring nature. The results for the three month period ended March 31, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. Reclassifications Certain amounts and disclosures in prior years have been reclassified to conform to the current year presentation. Changes to operating segments During the first quarter of 2023 the Company changed the way management internally reviews and evaluates operating performance and manages the business. The Company determined it has four reportable segments: Çöpler, Marigold, Seabee and Puna. The Company’s previous exploration, evaluation and development properties are now managed by the nearest or adjacent reportable segment except for greenfield standalone prospects, which are included in Corporate and other. Prior period segment information has been recast to conform with current period presentation.

INCOME AND MINING TAXES

INCOME AND MINING TAXES	3 Months Ended
	Mar. 31, 2023
Income Tax Disclosure [Abstract]
INCOME AND MINING TAXES	INCOME AND MINING TAXES The Company’s consolidated effective income tax rate was 8.8% for the first three months of 2023 compared to 29.2% for the first three months of 2022. The primary driver of the change in the effective rate is foreign currency fluctuations and the release of uncertain tax positions, although these tax benefits were partially offset by tax return adjustments, including the newly implemented Türkiye earthquake tax. The Company’s statutory tax rate for the period is 27.0%. The effective rate differs from the statutory rate primarily due to the release of uncertain tax positions, partially offset by tax return adjustments, which are largely attributable to the Türkiye earthquake tax assessments. Unrecognized Tax Benefits The Company records uncertain tax positions on the basis of a two-step process in which (1) the Company determines whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions meeting the “more-likely-than-not” recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. A reconciliation of the beginning and ending amount of gross unrecognized tax benefits, inclusive of interest and penalties, is as follows (in thousands): Three Months Ended March 31, 2023 2022 Balance as of January 1 $ 8,574 $ — Increase associated with tax positions taken during the current year — — Increase (decrease) associated with tax positions taken during a prior year (1) (6,594) — Settlements — — Decrease associated with lapses in statutes of limitation — — Balance as of March 31 (1) $ 1,980 $ — (1) Of the gross unrecognized tax benefits, $2.0 million were recognized as current liabilities in Condensed Consolidated Balance Sheet as of March, 31, 2023. As of March 31, 2023 and December 31, 2022, $2.0 million and $8.6 million, respectively, represent the amount of unrecognized tax benefits, inclusive of interest and penalties that, if recognized, would impact the Company’s effective income tax rate. As of March 31, 2023 and December 31, 2022, the total amount of accrued income-tax-related interest and penalties included in the Condensed Consolidated Balance Sheets were nil and $5.2 million. The Company believes it is reasonably possible that the total amount of the unrecognized tax benefit of $2.0 million will be settled in the next 12 months. During the three months ended March 31, 2023, the Company released $6.6 million of tax, interest and penalties in Income and mining tax benefit (expense) in the Condensed Consolidated Statements of Operations.

Earnings Per Share [Abstract]
INCOME (LOSS) PER SHARE	INCOME (LOSS) PER SHARE The Company calculates basic net income (loss) per share using, as the denominator, the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share uses, as its denominator, the weighted average number of common shares outstanding during the period plus the effect of potential dilutive shares during the period. Potential dilutive common shares include stock options, Restricted Share Units (“RSUs”), and convertible notes for periods in which the Company has reported net income (loss). The calculations of basic and diluted net income (loss) per share attributable to stockholders of the Company for the three months ended March 31, 2023 and 2022 are based on the following (in thousands): Three Months Ended March 31, 2023 2022 Net income (loss) $ 29,004 $ 76,106 Net (income) loss attributable to non-controlling interest 809 (8,543) Net income (loss) attributable to shareholders of SSR Mining 29,813 67,563 Interest saving on 2019 Notes, net of tax 1,221 1,215 Net income (loss) used in the calculation of diluted net income per share $ 31,034 $ 68,778 Weighted average number of common shares outstanding 206,778 212,423 Adjustments for dilutive instruments: Stock options — 9 Restricted share units 14 88 2019 Notes 12,611 12,216 Diluted weighted average number of shares outstanding 219,403 224,736 Net income (loss) per share attributable to common shareholders Basic $ 0.14 $ 0.32 Diluted $ 0.14 $ 0.31

FAIR VALUE MEASUREMENTS AND FIN

FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS	3 Months Ended
	Mar. 31, 2023
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS	FAIR VALUE MEASUREMENTS AND FINANCIAL INSTRUMENTS Fair value accounting establishes 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 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2 - Quoted prices in markets that are not active, quoted prices for similar assets or liabilities in active markets, quoted prices or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability and model-based valuation techniques (e.g. the Black-Scholes model) for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following tables set forth the Company’s assets and liabilities measured at fair value on a recurring (at least annually) and nonrecurring basis by level within the fair value hierarchy (in thousands): Fair value at March 31, 2023 Level 1 (1) Level 2 (2) Level 3 (3) Total Assets: Cash $ 561,783 $ — $ — $ 561,783 Restricted cash 34,029 — — 34,029 Marketable securities 38,203 — — 38,203 Trade receivables from provisional sales, net — 80,639 — 80,639 Deferred consideration — — 22,284 22,284 $ 634,015 $ 80,639 $ 22,284 $ 736,938 Fair value at December 31, 2022 Level 1 (1) Level 2 (2) Level 3 (3) Total Assets: Cash $ 655,453 $ — $ — $ 655,453 Restricted cash 33,653 — — 33,653 Marketable securities 44,841 — — 44,841 Trade receivables from provisional sales, net — 49,897 — 49,897 Deferred consideration — — 24,369 24,369 $ 733,947 $ 49,897 $ 24,369 $ 808,213 (1) Marketable securities of publicly quoted companies, consisting of investments, are valued using a market approach based upon unadjusted quoted prices in an active market obtained from securities exchanges. (2) At times, the Company manages a portion of its exposure to fluctuation in diesel prices and foreign currency exchange rates through hedges; however, as of March 31, 2023 the Company does not have any outstanding hedge positions. In periods when the Company has open hedge positions, the derivative asset and liabilities are valued using pricing models with inputs derived from observable market data, including quoted prices in active markets. The Company’s provisional metal sales contracts, included in Trade and other receivables in the Condensed Consolidated Balance Sheets, are valued using inputs derived from observable market data, including quoted commodity forward prices. The inputs do not involve significant management judgment. Such instruments are classified within Level 2 of the fair value hierarchy. (3) Certain items of deferred consideration are included in Level 3, as certain assumptions used in the calculation of the fair value are not based on observable market data. The following table reconciles the beginning and ending balances for financial instruments that are recognized at fair value using significant unobservable inputs (Level 3) in the condensed consolidated financial statements (in thousands): Three Months Ended March 31, 2023 2022 Balance as of January 1 $ 24,369 $ 22,610 Revaluations (2,085) 651 Balance as of March 31 $ 22,284 $ 23,261 Fair values of financial assets and liabilities not already measured at fair value The fair value of the 2019 Notes and Term Loan as compared to the carrying amounts were as follows (in thousands): March 31, 2023 December 31, 2022 Level Carrying amount Fair value Carrying amount Fair value 2019 Notes (1) 1 $ 226,745 $ 251,850 $ 226,510 $ 257,025 Term Loan (2) 2 52,500 53,367 70,000 71,419 Total borrowings $ 279,245 $ 305,217 $ 296,510 $ 328,444 (1) The fair value disclosed for the Company's 2019 Notes is designated as Level 1 as the basis of valuation uses a quoted price in an active market. (2) The fair value disclosed for the Company's Term Loan is designated as Level 2 as the fair value is determined by an independent third-party pricing source.

The Company’s provisional metal sales contracts, included in Trade and other receivables in the Condensed Consolidated Balance Sheets, are valued using inputs derived from observable market data, including quoted commodity forward prices. The inputs do not involve significant management judgment. Such instruments are classified within Level 2 of the fair value hierarchy. (3) Certain items of deferred consideration are included in Level 3, as certain assumptions used in the calculation of the fair value are not based on observable market data.
