SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 31, 2025
Accounting Policies [Abstract]
Risks and Uncertainties	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; and Deferred income tax assets 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. The Company's business may be impacted by adverse macroeconomic and geopolitical conditions. These conditions include inflation, interest rate and foreign currency fluctuations and slowdown of economic activity around the world. The Company maintains its cash and cash equivalents primarily in United States dollars (“USD”). Any fluctuation in the exchange rate of the Turkish Lira (“TRY”), Canadian Dollar (“CAD”), Argentine Peso (“ARS”), or the currency of any other country in which the Company operates, against the USD could result in a loss on the Company’s books to the extent the Company holds funds or net monetary or non-monetary assets denominated in those currencies, and any fluctuations of currency prices generally may result in volatility. Certain of the Company's operations are located in countries that have in the past and are currently experiencing high rates of inflation. It is possible that in the future, high inflation in the countries in which we operate may result in an increase in operational costs in local currencies (without a concurrent devaluation of the local currency of operations against the dollar or an increase in the dollar price of gold, silver, copper, zinc or lead). Maintaining operating costs in currencies subject to significant inflation could expose us to risks relating to devaluation and high domestic inflation. The Company's business may also be impacted by physical risks that can impact each of its properties, such as those experienced in connection with the Çöpler Incident.
Business combinations	Business Combinations The Company recognizes and measures the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date, while transaction and integration costs are expensed as incurred. Any excess of the purchase consideration when compared to the fair value of the net tangible and intangible assets acquired, if any, is recorded as goodwill. For material acquisitions, the Company engages third-party valuation specialists to assist with the determination of the fair value of assets acquired, liabilities assumed, non-controlling interest, if any, and goodwill, based on recognized business valuation methodologies. An income, market or cost valuation method may be utilized to estimate the fair value of the assets acquired, liabilities assumed, and non-controlling interest, if any, in a business combination. If the initial accounting for the business combination is incomplete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition date, and not later than one year from the acquisition date, the Company will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the date of the acquisition. Any adjustment that arises from information obtained that did not exist as of the date of the acquisition will be recorded in the period the adjustment arises. If the business combination provides for contingent consideration, the Company records the contingent consideration at fair value at the acquisition date. Changes in fair value of contingent consideration resulting from events after the acquisition date are recognized as follows: (1) if the contingent consideration is classified as a liability, the changes in fair value and accretion costs are recognized in earnings, or (2) if the contingent consideration is classified as equity, the contingent consideration is not re-measured and its subsequent settlement is accounted for within equity. The increases or decreases in the fair value of contingent consideration can result from a change in the timing of the contingent event and changes in assumed discount periods and rates.
Basis of Presentation	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 (“GAAP”) 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, 2024 filed on February 18, 2025. 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, 2025, are not necessarily indicative of the results that may be expected for the year ending December 31, 2025.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2024-03 “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) (“ASU 2024-03”).” ASU 2024-03 requires public business entities to disclose additional information about specific expense categories in the notes to financial statements. The new standard is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027 with early adoption permitted. ASU 2024-03 should be applied either (1) prospectively to financial statements issued for reporting periods after the effective date, or (2) retrospectively to any or all prior periods presented in the financial statements. The Company is currently evaluating the impact of the new standard on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” ASU 2023-09 enhances the transparency and decision usefulness of income tax disclosures through changes to the rate reconciliation and income taxes paid information. The standard is effective beginning with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025, and subsequent interim periods, with early adoption permitted. The Company is currently evaluating the impact of the standard on the consolidated financial statements.
