Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The significant accounting policies used in the preparation of these consolidated financial statements are as follows: Risks and uncertainties As a mining company, the revenue, profitability and future rate of growth of the Company are substantially dependent on the prevailing prices for gold, silver, zinc and lead. The prices of these metals are volatile and affected by many factors beyond the Company’s control, 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 particularly 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. COVID-19 During the year ended December 31, 2021, the COVID-19 pandemic continued to impact global economic and financial markets, disrupting global supply chains and workforce participation. Many industries and businesses, including the Company, continue to be impacted by the COVID-19 pandemic and face operating challenges associated with the regulations and guidelines resulting from efforts to contain COVID-19. The Company continues to restrict all non-essential travel and manage the contacts of its employees and contractors in order to reduce the risk of COVID-19 impacting its operations. The Company is operating its corporate offices at reduced capacity, with most employees working remotely. The Company's mine sites remain operational with carefully managed COVID-19 based restrictions designed to protect communities and employees, including quarantining, testing, ensuring physical distancing and providing additional protective equipment. Basis of preparation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Previously, the Company prepared its consolidated financial statements under International Financial Reporting Standards ("IFRS") as permitted by securities regulators in Canada, as well as in the United States under the status of a Foreign Private Issuer as defined by the United States Securities and Exchange Commission ("SEC"). As of June 30, 2021, the Company determined that it no longer qualified as a Foreign Private Issuer under the SEC rules. As a result, beginning January 1, 2022 the Company is required to report with the SEC on domestic forms and comply with domestic company rules in the United States. The transition to U.S. GAAP was made retrospectively for all periods from the Company’s inception. New accounting standards implemented subsequent to January 1, 2019 were adopted on their required adoption date. Use of estimates Preparing financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management’s estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production depreciation; reclamation liabilities; valuation of assets acquired and liabilities assumed in business combinations; estimates of fair value for certain reporting units and asset impairments (including impairments of long-lived assets and goodwill); estimates of recoverable metal in stockpile and leach pad inventories; estimates of the net realizable value of inventory, stockpiles and ore on leach pads; and estimates of deferred tax assets and liabilities. The Company has based its estimates on historical experience and various other assumptions that it believes to be reasonable. Accordingly, actual results may differ materially from these estimates under different assumptions or conditions. Changes in facts and circumstances may alter such estimates and affect the results of operations and financial position in future periods. Principles of consolidation These consolidated financial statements include the accounts of SSR Mining Inc., its wholly owned subsidiaries, and variable interest entities (“VIEs”) in which it is the primary beneficiary. Intercompany assets, liabilities, equity, income, expenses, and cash flows between SSR Mining Inc. and its subsidiaries have been eliminated on consolidation. Investments in joint ventures in which the Company has significant influence and VIEs where the Company is not the primary beneficiary are accounted for under the equity method of accounting. Operating segments The Company has five reportable segments for financial reporting purposes: Çöpler, Marigold, Seabee, Puna and the exploration, evaluation and development properties. Çöpler, Marigold, Seabee and Puna segments represent the Company's four operating mine sites. The exploration, evaluation and development properties segment represents a portfolio of prospective exploration tenures, both near or adjacent to the existing operations (near-mine) and greenfield standalone prospects, across Turkey, the U.S., Canada, Mexico and Peru. For further information refer to Note 4. 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 independent 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. Foreign currency transactions The functional and reporting currency of SSR Mining and each of its subsidiaries is the USD. Accordingly, foreign currency transactions and balances of the Company’s subsidiaries are remeasured as follows: (i) monetary assets and liabilities denominated in currencies other than the USD (“foreign currencies”) are remeasured into USD at the exchange rates prevailing at the balance sheet date; and (ii) non-monetary assets denominated in foreign currencies and measured at other than fair value are remeasured using the rates of exchange at the transaction date. Foreign exchange gains and losses are recognized in Foreign exchange gain (loss) in the Consolidated Statements of Operations. Unrealized foreign exchange gains and losses on cash and cash equivalent balances denominated in foreign currencies are disclosed separately in the Consolidated Statements of Cash Flows. Cash and cash equivalents Cash and cash equivalents include cash on hand and held at banks and short-term investments with an original maturity of three months or less, which are readily convertible into a known amount of cash. Restricted cash is presented separately in Restricted cash in the Consolidated Balance Sheets. Restricted cash is deposited at banks and financial institutions and represents both a debt service reserve account and reclamation reserve account. Inventories Stockpiled ore, leach pad inventory, work-in-process inventory, and finished goods are valued at the lower of average cost or net realizable value (“NRV”). NRV is calculated using the estimated price at the time of sale based on prevailing and forecasted metal prices, less estimated future production costs to convert the inventory into saleable form, depreciation, and all associated selling costs. Costs include all direct costs incurred in production, including direct labor and materials, freight, depletion and depreciation, and directly attributable overhead costs. Any write-downs of inventory to NRV are recognized within Production costs and Depreciation, depletion, and amortization in the Consolidated Statements of Operations. Stockpiled ore represents ore that has been extracted from the mine and is available for further processing. The cost of stockpiled ore is derived from the current mining costs incurred up to the point of stockpiling the ore and is removed at the weighted average cost as ore is processed. Quantities of stockpiled ore are verified by periodic surveys. Stockpiled ore that is not expected to be processed within the next twelve months is classified as non-current. Leach pad inventory represents ore that has been mined and placed on leach pads where a solution is applied to the surface of the heap to dissolve the gold and by-products. The resulting solution is further processed in a plant to recover the gold. The cost of leach pad inventory is derived from current mining and leaching costs and is removed as ounces of gold are recovered at the weighted average cost per recoverable ounce of gold on the leach pads. Estimates of recoverable gold in the leach pads are calculated based on the quantities of ore placed on the leach pads (measured tonnes added to the leach pads), the grade of ore placed on the leach pads (based on assay data), and an estimated recovery percentage (based on estimated recovery assumptions from the block model). The nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, estimates are refined based on actual results and engineering studies over time. The final recovery of gold from leach pads will not be known until the leaching process is concluded at the end of the mine life. Ore on leach pads that is not expected to be recovered within the next twelve months is classified as non-current. Work-in-process inventory represents material that is currently in the process of being converted to a saleable product, whether being processed in a mill or following recovery from a leach pad. Work-in-process inventory is determined based on assays of the material fed into the process and the projected recoveries of the respective processing plants. Work-in-process inventory is valued at the lower of average cost of the material fed into the process plus the in-process conversion costs, including applicable depreciation relating to the process facilities, or NRV. Finished goods inventory includes metal concentrates at site and in transit, doré at a site or a refinery, or gold bullion and are valued at the lower of the average cost of the respective in-process inventories incurred prior to the refining process, plus applicable refining costs, or NRV. Costs are transferred from finished goods inventory and recorded as Production costs and Depreciation, depletion and amortization in the Consolidated Statements of Operations upon sale. Materials and supplies inventories are measured at the lower of average cost or NRV. A regular review is undertaken to determine the extent of any reserve for obsolescence. Mineral properties, plant and equipment Mineral properties Mineral properties are capitalized at fair value at the acquisition date. Mineral properties may include mineral reserves, mineral resources and exploration potential. Mineral reserves represent the estimate of ore that can be economically and legally extracted from the Company's mining properties. Production stage mineral properties are operating properties that contain proven and probable reserves and are amortized using the units-of-production method based on the estimated recoverable ounces or pounds in proven and probable reserves. Development stage mineral properties are those under development that contain proven and probable reserves. Exploration stage mineral properties are those that potentially contain mineralized material, consisting of (i) areas adjacent to existing mineral resources and mineralization located within the immediate mine area; (ii) areas outside of immediate mine areas that are not part of mineral resources; and (iii) greenfield exploration potential that is not associated with any other production, development, or exploration stage property. Mineral properties in the development and exploration stage are not amortized until the property is converted to the production stage. Mineral exploration costs, including costs associated with prospecting, sampling, mapping, diamond drilling and other work involved in searching for mineral resources are charged to Exploration, evaluation and reclamation costs as incurred. Mine development Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Capitalization of mine development project costs that meet the definition of an asset begins once mineralization is classified as proven and probable reserves. Drilling and related costs are capitalized for an ore body where proven and probable reserves exist, and the activities are directed at obtaining additional information about the ore body or converting mineralized material to proven and probable reserves. All other drilling and related costs are expensed as incurred. Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of Production costs . The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Where multiple open pits exist at a mining complex utilizing common processing facilities, pre-stripping costs are capitalized for each pit. The removal, production, and sale of de minimis saleable materials may occur during the development phase of an open pit mine and are assigned incremental mining costs related to the removal of that material. The production phase of an open pit mine commences when saleable minerals, beyond a de minimis amount, are produced. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Production costs in the same period as the revenue from the sale of inventory. Mine development costs are amortized using the units-of-production method based on estimated recoverable ounces or pounds in proven and probable reserves. To the extent that these costs benefit an entire ore body, they are amortized over the estimated life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block or area. Plant and equipment Expenditures for new facilities or equipment and expenditures that extend the useful lives of existing facilities or equipment are capitalized and recorded at cost. Facilities and equipment acquired as part of a finance lease are capitalized and recorded as right-of-use ("ROU") assets based on the contractual lease terms. The carrying amounts of plant and equipment are depreciated to their estimated residual value over the estimated useful lives of the specific assets or the estimated life-of-mine ("LOM"), if shorter. Depreciation starts on the date when the asset is available for its intended use. Construction in process assets are not depreciated until available for their intended use. The major categories of plant and equipment are depreciated on a straight-line basis using the estimated lives indicated below: Vehicles 5 years - 7 years Mining equipment 3 years - 21 years Mobile equipment components 2 years - 7 years Buildings 5 years - 21 years Mine plant equipment 3 years - 21 years Underground infrastructure 5 years - 21 years ROU assets - plant and equipment (1) 10 years - 21 years (1) For ROU assets, the depreciation period indicated above represents the period from lease commencement date to the earlier of the end of the useful life of the underlying asset or the end of the lease term. Impairment of long-lived assets The Company assesses the carrying value of its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable. Events or circumstances that could indicate that the carrying value of an asset or asset group may not be recoverable include, but are not limited to, significant adverse changes in the business climate including changes in future metal prices, significant changes to the extent or manner in which the asset is being used or its physical condition including significant decreases in production or mineral reserves, and significant decreases in the market price of the assets. In evaluating long-lived assets for recoverability, estimates of undiscounted future cash flows of the Company's mines are used. An impairment is considered to exist if total estimated undiscounted future cash flows are less than the carrying amount of the asset. Once it is determined that an impairment exists, and impairment loss is recognized based on the difference between the estimated fair value of the long-lived assets and their carrying amounts. Fair value is typically determined through the use of an income approach utilizing estimates of discounted future cash flows. Future cash flows are derived from current business plans which are developed using short and long-term metal price assumptions; estimates of costs; and resource, reserve and exploration potential estimates, including timing and costs to develop and produce the material and are considered Level 3 fair value measurements. The Company believes its estimates and models used to determine fair value are similar to what a market participant would use. Goodwill Under the acquisition method of accounting for business combinations, the identifiable assets acquired and liabilities assumed are recognized at their estimated fair value as of the date of acquisition. The excess of the fair value of consideration paid over the fair value of the identifiable net assets acquired is recognized as Goodwill and allocated to the reporting units. Goodwill is allocated to reporting units and assessed for impairment annually as of December 31 and when events or circumstances indicate that the carrying value of a reporting unit exceeds its fair value. In testing for goodwill impairment, the Company first evaluates qualitative factors to determine whether the existence of events or circumstances indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is determined that it is more likely than not that the fair value is less than the carrying value, then a quantitative goodwill impairment test is performed by determining the fair value of the reporting unit. The fair value of a reporting unit is determined using either the income approach by utilizing estimates of discounted future cash flows or the market approach utilizing recent transaction activity for comparable properties. These approaches are considered Level 3 fair value measurements. If the carrying amount of a reporting unit exceeds the fair value, an impairment loss is recognized in the current period in an amount equal to the excess. Stock-based compensation The Company determines the fair value on the grant date for stock-based compensation awards and expenses the awards in the Consolidated Statements of Operations over the vesting period on a straight-line basis. Based on the terms of the award, and the Company’s intent and past practice for settlement in cash or shares, the awards are classified as liabilities or equity. The Company recognizes forfeitures as they occur. Cash-settled stock-based compensation arrangements; including Deferred Share Units (“DSUs”), DSU Replacement Units, Performance Stock Units (“PSUs”), and PSU Replacement Units are remeasured at fair value at the end of each reporting period and at the date of settlement, with any changes in fair value recognized in profit or loss for the period. For equity-settled stock options, the fair value at the grant date is estimated using the Black-Scholes option pricing model. For Restricted Share Units (“RSUs”) and RSU Replacement Units, the fair value at the grant date is estimated based on the quoted market price of the Company’s common stock. Income taxes The income tax and mining expense for the period is comprised of current tax expense and deferred tax expense, and is recognized in the Consolidated Statements of Operations. Current income tax Current tax for each of the Company's taxable entities is based on the local taxable profit for the period at the local statutory tax rates enacted at the date of the Consolidated Balance Sheets as well as the available double tax treaty rates as ratified. Management periodically evaluates positions taken in tax returns in situations in which applicable tax regulation is subject to interpretation. The Company establishes provisions where appropriate on the basis of amounts expected to be paid to tax authorities. Any uncertain tax positions must meet a more-likely-than-not realization threshold to be recognized and any potential accrued interest and penalties related to unrecognized tax benefits are recognized within Income tax benefit (expense) . Deferred tax Deferred income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are determined by applying the enacted statutory tax rates in effect at the end of a reporting period to the cumulative temporary differences between the tax bases of assets and liabilities and their reported amounts in the Company’s consolidated financial statements. Deferred income tax assets are recognized for all deductible temporary differences to the extent that it is more likely than not that taxable profits will be available to be utilized against those deductible temporary differences. A valuation allowance for deferred tax assets is established when it is more likely than not that some portion of the benefit from deferred tax assets will not be realized. The extent to which deductible temporary differences, unused tax losses and other income tax deductions are expected to be realized are reassessed at the end of each reporting period. The effect on deferred taxes for a change in tax rates is recognized in income during the period that the enactment date is effective. Deferred tax assets are recognized for investment incentive tax credits in Turkey in the period earned as expenditures that are more likely than not to be accepted as eligible spend occur and it is more likely than not that taxable profits will be available to be utilized against those credits, which can be applied to current and future year income tax payments. The Company accounts for the investment incentive tax credit in Turkey using the flow-through method. Under this method, the investment incentive tax credit is treated as a reduction of income taxes in the year in which the credit arises. Deferred income tax liabilities are not recognized for taxable temporary differences associated with investments in subsidiaries and associates, and interests in joint ventures, unless it becomes apparent that the excess book over tax basis difference is expected to reverse in the foreseeable future. Accordingly, deferred income tax assets and liabilities are recognized for future withholding taxes payable where it has been determined that the amount would reasonably be payable in the foreseeable future. Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset the current tax assets against the current tax liabilities, when they relate to income taxes levied by the same taxation authority, and the Company intends to settle its current tax assets and liabilities on a net basis. Mining taxes and other tax arrangements Mining taxes or royalties and other arrangements are treated as taxation arrangements when they have the characteristics of an income tax. This is the case when they are imposed under government authority and the amount payable is calculated by reference to an income measure. Obligations arising from royalty arrangements that do not satisfy these criteria are recognized as current liabilities and included within Production costs . Investments The Company has investments in debt securities and marketable equity securities. The Company determines the appropriate classification of debt securities at the time of purchase and re-evaluates such determinations at each reporting date. Current investments include marketable equity securities and held to maturity and available for sale debt securities. Marketable equity securities are carried at fair value. Held to maturity securities, classified based on the intent and ability to hold the securities to maturity, are carried at amortized cost. Marketable debt securities are categorized as available for sale and carried at fair value. Gains and losses on the sale of securities are recognized on a specific identification basis. Unrealized gains and losses are included in Other income (expense) on the Consolidated Statements of Operations. Derivative financial instruments The Company is exposed to various market risks, including the effect of changes in metal prices and foreign exchange rates, and from time to time uses derivatives to manage financial exposures that occur in the normal course of business. The Company recognizes derivatives as either assets, presented in the Consolidated Balance Sheets in Prepaid and other current assets or Other non-current assets , or liabilities, presented in the Consolidated Balance Sheets in Accrued liabilities and other or Other non-current liabilities , and measures those instruments at fair value. These are considered Level 2 fair value measurements. Changes in the value of derivative instruments are recorded each period in Production Costs or Other income (expense) on the Consolidated Statements of Operations. Management applies judgment in estimating the fair value of instruments that are highly sensitive to assumptions regarding commodity prices, market volatilities, and foreign currency exchange rates. The Company currently does not apply hedge accounting. Reclamation liabilities The Company recognizes a liability for the fair value of estimated future reclamation costs when incurred. The liability is accreted over time through periodic charges to Exploration, evaluation and reclamation costs in the Consolidated Statements of Operations. In addition, the asset retirement cost is capitalized as part of the asset's carrying value and amortized over the life of the related asset. Reclamation liabilities are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of reclamation costs. Changes in the estimate of reclamation costs may result from changes in legal or regulatory requirements, increased obligations arising from additional mining and exploration activities, and changes to cost estimates. Changes in reclamation estimates at mines that are not currently operating, as the mine or portion of the mine site has entered the closure phase and has no substantive future economic value, are reflected in Exploration, evaluation and reclamation costs in the Consolidated Statements of Operations. The estimated reclamation obligation is based on when spending for an existing disturbance is expected to occur. The Company reviews, on an annual basis, unless otherwise deemed necessary, the reclamation obligation at each mine site. Leases The Company has entered into lease contracts under which it is the lessee. The Company determines whether an arrangement is, or contains, a lease based on the substance of the arrangement at its inception. If the contract is determined to be a lease, the Company classifies the lease as either an operating or financing lease. Operating lease right of use ("ROU") assets are included in Other non-current assets and lease obligations are included in Accrued liabilities and other and Other non-current liabilities in the Consolidated Balance Sheets. Finance lease ROU assets are included in Mineral properties, plant and equipment and lease obligations are included in Finance lease liabilities in the Consolidated Balance Sheets. ROU assets represent the Company’s right to use the underlying assets for the lease term and the corresponding lease liabilities represent its obligations to make lease payments arising from the leases. Operating and finance lease ROU assets and liabilities are recognized at the commencement date based on the present value of the expected lease payments over the lease term. When the rate of interest implicit in the lease cannot be readily determined, the Company uses its incremental borrowing rate in determining the present value of future lease payments. Operating lease costs are recognized on a straight-line basis over the lease term. Finance lease costs are recognized based on the effective interest method for the lease liability and straight-line amortization of the ROU asset, resulting in more cost being recognized in earlier periods. Variable lease payments are recognized in the period in which they are incurred. The Company has elected certain practical expedients including the short-term lease recognition exemption for all classes of underlying assets. Accordingly, leases with a term of one year or less have not and will not be recognized on the Consolidated Balance Sheets. The Company has also elected the practical expedient to not separate lease and non-lease components such as taxes and common area maintenance charges, in certain classes of assets such as its office facilities. Most of the Company’s leasing arrangements include extension and termination options, all of which provide the Company flexibility in retaining the underlying facilities and equipment, as well as some protection from future price variability. The Company has applied judgment to determine the lease term, which is the non-cancelable period in the contract, plus the period beyond that cancellation period that the Company believes it is reasonably certain it will need the equipment for operational purposes. Revenue recognition The Company generates revenue by selling gold, copper, silver, lead and zinc produced from its mining operations. The majority of the Company’s sales come from the sale of refined gold bullion; however, the end product at the Company’s gold operations is generally doré bars. The Company also sells silver-lead and zinc concentrate to smelters for further treatment and refining. Gold sales Doré is sent to refiners to produce bullion that meets the required market standard of 99.95% gold. Under the terms of the Company’s refining agreements, the doré bars are refined for a fee, and the Company’s share of the refined gold and separately recovered silver is credited to its bullion account. Doré produced at Marigold and Seabee is sold primarily to bullion banks in the London spot market. Doré produced at Çöpler is sold primarily on the Istanbul Gold Exchange. Under legislation commenced in Turkey in 2018,

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS AND DIVESTITURES	ACQUISITIONS AND DIVESTITURES Acquisition of Taiga Gold Corporation On December 2, 2021, the Company announced an agreement to acquire all the issued and outstanding common shares of Taiga Gold Corporation (“Taiga Gold”) at a price of CAD $0.265 per Taiga Gold share which implies an equity value of approximately $21.0 million. Taiga Gold has announced that it intends to call a meeting of shareholders to be held on or before March 15, 2022 to seek shareholder approval for the Transaction. The transaction will require approval of (i) at least 66⅔% of the votes cast by Taiga Gold shareholders and (ii) a simple majority of the votes cast by certain Taiga Gold shareholders, which excludes votes from certain shareholders, as required under Canadian Multilateral Instrument 61-601 - Protection of Minority Securityholders in Special Transactions . The completion of the transaction is also subject to receipt of court, stock exchange and any other regulatory approvals, and is subject to customary closing conditions for transactions of this nature. The agreement provides for non-solicitation covenants with "fiduciary out" provisions that allow Taiga Gold to consider and accept a superior proposal, subject to a "right to match period" in favor of the Company. The agreement also provides for (i) a termination fee of $1.2 million to be paid by Taiga Gold to the Company if the agreement is terminated in certain specified circumstances; and (ii) and expense reimbursement fee of $0.3 million to be paid by the Company to Taiga Gold if the transaction fails to close as a result of specified breaches of the agreement by the Company. The transaction is expected to close in the first half of 2022. The transaction materially expands the Company’s presence in Saskatchewan, Canada, a core jurisdiction, by adding five new properties, which provide new exploration targets stretching south from the Seabee mine to the Company’s 100%-owned Amisk property. Further, the acquisition consolidates a 100% interest in the Fisher property contiguous to the Seabee mine, currently operated under joint venture comprised of the Company's 80% and Taiga Gold's 20%. The Company will leverage its existing teams and infrastructure to advance the development of these assets. Acquisition of Alacer Gold Corporation On September 16, 2020 (“Acquisition Date”), the Company acquired all of the issued and outstanding common shares of Alacer Gold Corp. ("Alacer"). The acquisition of Alacer created a diversified portfolio of high quality, long-life mines across four mining-friendly jurisdictions. The Company acquired all of the issued and outstanding common shares of Alacer, with Alacer shareholders receiving 0.3246 of the Company’s common stock for every one Alacer share (the "Exchange Ratio"). The transaction resulted in the issuance of 95,699,911 of the Company’s common stock to the former shareholders of Alacer. All outstanding RSUs, PSUs and DSUs of Alacer that were not exercised prior to the Acquisition Date were replaced with the Company units (the RSU Replacement Units, the PSU Replacement Units, and the DSU Replacement Units, respectively), with the number of such securities issued adjusted by the Exchange Ratio. Upon closing of the transaction, the Company and former Alacer shareholders owned 57% and 43%, respectively, of the shares of the combined entity. Upon the completion of the transaction, Alacer became a wholly-owned subsidiary of the Company. Alacer holds an 80% interest in Anagold Madencilik Sanayi ve Ticaret Anonim Şirketi ("Anagold"), the owner and operator of Çöpler, a large-scale open pit gold mine in east-central Turkey. The 20% non-controlling interest in Anagold is held by Lidya Madencilik Sanayi ve Ticaret Anonim Şirketi ("Lidya Mining"). Based upon the September 15, 2020 closing stock price of the Company's common stock, the total purchase price consideration of the acquisition was $2.2 billion. The Company incurred transaction and integration costs of $6.9 million and $20.8 million, which included $11.0 million for severance and termination payments to executives, for the years ended December 31, 2021 and 2020, respectively. These costs were recognized in Transaction, integration and SEC conversion expense in the Consolidated Statements of Operations. The acquisition of Alacer was accounted for as a business combination which requires the measurement of acquired assets and liabilities assumed at their respective fair values at the date of acquisition. The Acquisition Date fair value of the consideration transferred consists of the following (in thousands): Share consideration (1) $ 2,127,284 RSU, PSU and DSU consideration (2) 52,363 Total consideration $ 2,179,647 (1) The fair value of 95,699,911 common shares issued to Alacer shareholders was determined using the Company's common share price of $22.22 per share on September 15, 2020. (2) The fair value of 3,570,261 RSU, 3,463,023 PSU and 1,158,071 DSU consideration units issued was determined using the Alacer share price of $7.21 on September 15, 2020, adjusted for the Exchange Ratio. Of the amount relating to the RSU, PSU and DSU consideration, $15.4 million was recognized in equity and $23.8 million and $13.2 million were recognized in Accrued liabilities and other and Other non-current liabilities, respectively. The table below presents the fair values of the assets acquired and liabilities assumed at the Acquisition Date (in thousands): ASSETS Cash and cash equivalents $ 270,445 Trade and other receivables 17,218 Inventories 224,992 Prepaids and other current assets 6,039 Mineral properties, plant and equipment 2,789,832 Inventories 124,775 Restricted cash 32,943 Equity method investments 9,148 Other non-current assets 9,575 Total assets $ 3,484,967 LIABILITIES Accounts payable and accrued liabilities $ 71,861 Current portion of debt 70,000 Debt 175,000 Reclamation liabilities (1) 26,154 Lease liabilities - non-current 114,820 Deferred income tax liabilities (2) 337,752 Other non-current liabilities 3,081 Non-controlling interest (3) 506,652 Total liabilities 1,305,320 Total net assets $ 2,179,647 (1) The fair value of reclamation costs is based on the expected amounts and timing of cash flows for closure activities and discounted to present value using a credit-adjusted risk-free rate as of the Acquisition Date. Key assumptions include the costs and timing of key closure activities based on the life of mine plans. (2) Deferred income tax liabilities are net of a deferred income tax asset of $182.9 million relating to investment incentive tax credits at Çöpler and includes a deferred income tax liability of $29.2 million for withholding tax on distributable earnings of the Turkish entities. (3) The fair value of non-controlling interest is measured based on a discounted cash flow model. The fair values of inventories were determined based on an NRV approach, whereby the future estimated cash flows from sales of payable metal produced are adjusted for costs to complete. The fair values of mineral properties have been estimated using discounted cash flow models and the fair values of plant and equipment have been estimated using a depreciated replacement cost approach. A market approach was used to estimate the fair values of certain exploration assets with reference to a public company comparable analysis. Expected future cash flows are based on estimates of future metal prices, production based on current estimates of mineral reserves and recoverable mineral resources, future operating costs and capital expenditures, and discount rates. The valuation of net deferred tax liabilities includes an amount recognized for deferred tax assets relating to investment incentive tax credits for which the Company has determined it is more likely than not to be accepted as eligible spend occurs and it is more likely than not that taxable profits will be available to utilize against those credits. Consolidated revenue for the year ended December 31, 2020 includes revenue from the assets acquired in the acquisition of Alacer of $205.5 million. Consolidated net income for the year ended December 31, 2020 includes net income attributable to SSR Mining shareholders from Alacer o f $24.1 million. Pro forma financial information The following table provides unaudited pro forma financial information for the years ended December 31, 2020 and 2019, as if Alacer had been acquired as of January 1, 2019 (in thousands): Years Ended December 31, 2020 2019 Revenue $ 1,215,145 $ 1,077,093 Net income attributable to SSR Mining shareholders $ 264,390 $ 219,068 Acquisition of non-controlling interest in Puna On September 18, 2019, the Company acquired a 25% interest in Puna from Golden Arrow Resources Corporation ("Golden Arrow") for aggregate consideration of $32.4 million, consisting of $2.3 million of cash, the extinguishment of the loan to Golden Arrow and related interest of $11.4 million, the issuance of $18.2 million of the Company's common shares, and the transfer of shares in Golden Arrow held by the Company, with a fair value of $0.5 million, for cancellation. As the acquisition did not result in a change of control, the acquisition was accounted for as an equity transaction whereby the carrying amount of the non-controlling interest of $33.9 million in Puna prior to the acquisition was adjusted to zero in the Consolidated Balance Sheets. Further, the difference of $1.5 million between the carrying amount of the non-controlling interest in Puna at the time of acquisition and the fair value of the consideration paid to Golden Arrow of $32.4 million was recognized in equity. Transaction costs incurred in connection with the transaction of $0.2 million were recognized as a reduction of equity. Divestiture of royalty assets

Segment Reporting [Abstract]
OPERATING SEGMENTS	OPERATING SEGMENTS The Company currently has four producing mines and a portfolio of precious metal dominant projects. Each individual operating mine site along with the Company's exploration, evaluation and development properties are considered reportable segments. Operating results of operating segments are reviewed by the Company's chief operating decision maker ("CODM") to make decisions about resources to be allocated to the segments and to assess their performance. The Company's business activities that not included within the reportable segments are included in Corporate and other. Although they are not required to be included in this footnote, they are provided for reconciliation purposes. In connection with the acquisition of Alacer, the Company added Çöpler as a new operating mine site for the year ended December 31, 2020. Çöpler is an operating mine site, therefore it is considered a reportable segment. The following tables provide a summary of financial information related to the Company's segments (in thousands): Year Ended December 31, 2021 Çöpler Marigold Seabee Puna Exploration, evaluation Corporate and other (1) Total Revenue $ 607,887 $ 426,391 $ 213,860 $ 226,061 $ — $ — $ 1,474,199 Production costs $ 264,889 $ 219,035 $ 66,354 $ 121,096 $ — $ — $ 671,374 Depletion, depreciation and amortization $ 125,220 $ 35,410 $ 45,334 $ 21,995 $ — $ — $ 227,959 Exploration, evaluation and reclamation costs $ 10,868 $ 2,979 $ 11,867 $ 1,764 $ 13,027 $ 1,877 $ 42,382 Care and maintenance expense (1) $ — $ — $ — $ — $ — $ — $ — Transaction, integration and SEC conversion expense $ — $ — $ — $ — $ — $ 11,240 $ 11,240 Impairment of long-lived and other assets $ — $ — $ — $ — $ 20,275 $ — $ 20,275 Operating income $ 201,302 $ 169,070 $ 90,332 $ 79,043 $ (33,302) $ (62,070) $ 444,375 Capital expenditures $ 34,699 $ 55,861 $ 40,553 $ 10,458 $ — $ — $ 141,571 Total assets as of December 31, 2021 $ 2,290,367 $ 566,015 $ 479,370 $ 293,470 $ 923,204 $ 659,012 $ 5,211,438 (1) Care and maintenance expense consists of operating costs and depreciation incurred while a site is placed into care and maintenance or operating at reduced levels in response to the COVID-19 pandemic.

The application of these tax credits, which are denominated in Turkish Lira, reduced income and mining tax expense and cash tax payments for the year ended December 31, 2021 and are expected to offset future cash tax payments. Reviews of eligible expenditures for tax credits by local tax authorities occur periodically and can result in adjustments to the recognition of investment incentive tax credits. As of December 31, 2021 and 2020, an aggregate deferred tax liability of $10.7 million and $14.1 million, respectively, for temporary differences of $35.6 million and $47.0 million, respectively, related to investments in subsidiaries was not recognized as the Company controls the dividend policy of its subsidiaries (i.e., the Company controls the timing of reversal of the related taxable temporary differences and is satisfied that they will not reverse in the foreseeable future). Valuation of deferred tax assets The Company recognizes tax benefits on losses or other deductible amounts generated in countries where it determines that it is more likely than not that taxable profits will be available to be utilized against those temporary differences. The Company's deferred tax valuation allowance related primarily to tax losses in foreign jurisdictions which do not meet the “more-likely-than-not” standard under current accounting guidance due to insufficient positive taxable income to utilize available tax losses. When there is a change in judgment concerning the recovery of deferred tax assets in future periods, a valuation allowance is recorded into earnings during the quarter in which the change in judgment occurs. During 2021, the Company made adjustments to its deferred tax assets and corresponding valuation allowances. The net change to the valuation allowance consisted of a $1.1 million increase related to reclamation liabilities with no future tax benefit and the generation of losses. Tax loss carryforwards As of December 31, 2021, the Company had the following estimated tax operating losses available to reduce future taxable income, including both losses for which deferred tax assets are utilized to offset applicable deferred tax liabilities and losses for which deferred tax assets are not recognized as listed in the table above. Losses expire at various dates and amounts between 2022 and 2041. There were no operating losses generated in Turkey. December 31, 2021 Expiration Year Mexico $ 34,695 2022 - 2031 Canada $ 42,632 2040 - 2041 U.S.A. $ 7,797 Indefinite Argentina $ 5,146 2026 Unrecognized tax benefits The Company records uncertain tax positions on the basis on 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. The Company determined that no liability for unrecognized tax benefits for uncertain tax positions was required as of December 31, 2021. In addition, the Company does not believe that it has any tax positions for which it is reasonably possible that it will be required to record a significant liability for previously recognized tax benefits within the next twelve months. If the Company were to record an unrecognized tax benefit, the Company will recognize applicable interest and penalties related to income tax matters in income and mining tax expense. The Company files income tax returns in the U.S. federal jurisdiction, Canada, Turkey, Argentina and various state, provincial and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. Federal, state and local, and non-US income tax examinations for years before 2016. The Company is currently litigating with Turkey for the years 2016 through 2020 related to withholding tax on distributions from its Turkish operation.

Potential dilutive common shares include stock options, PSUs and PSU Replacement Units, RSUs and RSU Replacement Units, and convertible notes for periods in which the Company has reported net income. The calculations of basic and diluted net income per share attributable to stockholders of SSR Mining for the years ended December 31 were based on the following (in thousands): Years Ended December 31, 2021 2020 2019 Net Income $ 425,922 $ 157,162 $ 101,218 Net (income) loss attributable to non-controlling interest (57,846) (5,627) 1,558 Net income attributable to stockholders of SSR Mining 368,076 151,535 102,776 Interest saving on convertible notes, net of tax 4,889 4,883 3,392 Net income used in the calculation of diluted net income per share $ 372,965 $ 156,418 $ 106,168 Weighted average number of common shares issued 215,993 151,144 121,769 Adjustments for dilutive instruments: Stock options 38 453 1,224 PSUs and PSU Replacement Units — — 5 RSUs and RSU Replacement Units 58 1 — Convertible notes 12,152 12,101 12,445 Diluted weighted average number of shares outstanding 228,241 163,699 135,443 Net income per share attributable to common stockholders Basic $ 1.70 $ 1.00 $ 0.84 Diluted $ 1.63 $ 0.96 $ 0.78

FAIR VALUE MEASUREMENTS AND FIN

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 December 31, 2021   Level 1 (1) Level 2 (2) Level 3 (3) Total Assets: Cash $ 1,017,562 $ — $ — $ 1,017,562 Restricted cash 35,303 — — 35,303 Marketable securities 46,923 — — 46,923 Trade receivables — 72,634 — 72,634 Derivative asset — 987 — 987 Deferred consideration — — 22,610 22,610 $ 1,099,788 $ 73,621 $ 22,610 $ 1,196,019   Fair value at December 31, 2020   Level 1 (1) Level 2 (2) Level 3 (3) Total Assets: Cash $ 860,633 $ — $ — $ 860,633 Restricted cash 35,288 — — 35,288 Marketable securities 26,748 — — 26,748 Trade receivables — 36,856 — 36,856 Derivative asset — 1,243 — 1,243 Deferred consideration — — 21,460 21,460 $ 922,669 $ 38,099 $ 21,460 $ 982,228 Liabilities: Derivative liabilities $ — $ (3,881) $ — $ (3,881) $ — $ (3,881) $ — $ (3,881) 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) The Company manages its exposure to fluctuation in diesel prices and foreign currency exchange rates through hedges. The Company’s 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 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 related to the sale of of exploration and evaluation assets and the EMX divestiture are included in Level 3, as certain assumptions used in the calculation of the fair value are not based on observable market data. Deferred consideration is included in Other non-current assets in the Consolidated Balance Sheets. 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 consolidated financial statements (in thousands):   2021 2020 Beginning Balance as of January 1 $ 21,460 $ 13,984 Revaluations 930 (1,059) Receipt of deferred consideration 20,911 8,535 Disposition of deferred consideration (20,691) — Ending balance as of December 31 $ 22,610 $ 21,460 The fair value of the deferred consideration was estimated using the discounted cash flow method. The discount rate used to calculate the Company's deferred consideration assets was between 8.0% and 12.5% at December 31, 2021 and between 8.0% and 20.0% at December 31, 2020. Increases to the discount rate will cause a decrease in the the estimated value of the deferred consideration. The timing of achievement of development milestones were considered in determining the fair value of the deferred consideration. 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: December 31, 2021 2020 Level Carrying amount Fair value Carrying amount Fair value 2019 Notes (1) 1 $ 225,534 $ 286,207 $ 224,586 $ 317,538 Term Loan (2) 2 140,000 144,871 210,000 221,943 Total borrowings $ 365,534 $ 431,078 $ 434,586 $ 539,481 (1) The fair value disclosed for the Company's 2019 Notes is included in Level 1 as the basis of valuation uses a quoted price in an active market.

Term Loan In connection with the acquisition of Alacer (see Note 3), the Company assumed a term loan (the "Term Loan"), with a fair value of $245.0 million at the date of acquisition, with a syndicate of lenders (BNP Paribas (Suisse) SA, ING Bank NV, Societe Generale Corporate & Investment Banking and UniCredit S.P.A.). The Term Loan bears interest at the London Inter-bank Offered Rate ("LIBOR") plus a fixed interest rate margin in the range of 3.50% to 3.70% depending on the tranche. On October 12, 2021, the Company amended its existing agreement and agreed to replacement of the LIBOR screen rate with an alternative screen rate when LIBOR ceases to exist. The Term Loan has no mandatory hedging or cash sweep requirements, no prepayment penalties, and final repayment is scheduled in the fourth quarter of 2023. In addition to the Term Loan, the Company assumed LIBOR interest rate swap contracts with underlying notional amounts of approximately 37% of the outstanding Term Loan balance as of December 31, 2020 through the duration of the interest rate management program, which ended in 2021. Restricted cash accounts must be maintained while the Term Loan is outstanding. As of December 31, 2021 and 2020, $32.9 million and $32.9 million of restricted cash relates to the Term Loan, respectively. Restricted cash is not available for use within one year and is classified as Restricted cash in the Consolidated Balance Sheets. Under the terms of the Term Loan, the Company is required to comply with the following financial covenants: ▪ historic and forecast debt service cover ratio greater than or equal to 1.20:1; ▪ loan life cover ratio greater than or equal to 1.30:1; and ▪ minimum tail reserves as a percentage of total reserves greater than or equal to 30%. As of December 31, 2021, the Company was in compliance with its externally imposed financial covenants in relation to the Term Loan and Credit Facility. The Company does not have any financial covenants in relation to the 2019 Notes. Credit Facility On August 4, 2015, the Company entered into a $75.0 million senior secured revolving credit facility (the "Credit Facility") with a syndicate of banks. The Credit Facility may be used for reclamation bonding, working capital and other general corporate purposes but can only be used to fund activities of entities that were in the SSR Mining group prior to the acquisition of Alacer (see Note 3). During 2017, the Company extended the maturity of the Credit Facility to June 8, 2020, and concurrently reduced applicable margins, increased covenant flexibility and added a $25.0 million accordion feature. On June 7, 2021, the Company amended its existing Credit Facility to extend its maturity to June 8, 2025 and increase the Credit Facility to $200.0 million with a $100.0 million accordion feature (the "Amended Credit Facility"). Amounts drawn under the Amended Credit Facility are subject to variable interest rates at LIBOR plus an applicable margin ranging from 2.0% to 3.0%, based on the Company's net leverage ratio. The Amended Credit Facility contains fallback language that replaces LIBOR with an alternative benchmark rate based on either SOFR or another alternative benchmark rate when LIBOR ceases to exist. Undrawn amounts are subject to a standby fee ranging from 0.4% to 0.6%, based on the Company's net leverage ratio. The Amended Credit Facility also provides for financial letters of credit at 66.0% of the applicable margin, undrawn fees are subject to a utilization fee of 0.25%, and standby fees are calculated as 25% of the drawn applicable margin plus a utilization fee ranging from 0.25% to 0.75%. All debts, liabilities and obligations under the Credit Facility are guaranteed by the Company's material subsidiaries and secured by certain of the Company's assets and material subsidiaries, and pledges of the securities of the Company's material subsidiaries, excluding Alacer entities. In connection with the Credit Facility, the Company must also maintain certain net tangible worth and ratios for interest coverage and net leverage. As of December 31, 2021, the Company was in compliance with these covenants. As of December 31, 2021 and 2020, the amount outstanding on the Credit Facility, included in Accrued liabilities and other , was $0.9 million and $0.7 million, respectively. Scheduled minimum debt repayments are as follows (in thousands): 2022 $ 71,093 2023 $ 70,918 2024 $ — 2025 $ — 2026 $ — Thereafter $ 230,000

LEASES

Leases [Abstract]
LEASES	LEASES The Company’s operating leases consist primarily of leases for office space, vehicles, and plant and mining equipment. These leases have a range of terms between three months to twenty years with renewal terms included in the contracts. Some are automatic renewals, and some are at the option of the Company. There are no restrictions placed upon the lessee by entering into these leases. The Company’s finance leases consist primarily of equipment. The Company's principal lease relates to its right to use the oxygen plant supplied by Air Liquide Gaz Sanayi ve Ticaret A.S. (the "Air Liquide Plant") at Çöpler which was assumed on the acquisition of Alacer (see Note 3). The Air Liquide Plant is used for the production, transportation and delivery of oxygen and liquid oxygen to support mining operations at Çöpler. Under the terms of the Air Liquide Plant lease, the Company pays variable monthly lease payments that depend on an index. In addition, the Company is subject to variable payments based on consumption and use which have been accounted for as non-lease components and included in Production costs . The Air Liquide Plant lease contains a non-cancellable period of 15 years ending in 2033 with options to extend for consecutive 2-year periods. The lease term used in the measurement of the Company's lease liability and right-of-use asset includes four consecutive 2-year extension periods ending in 2041 for which the Company is reasonably certain to exercise its option in line with the Çöpler LOM. The Company uses its incremental borrowing rate as the discount rate to determine the present value of the lease payments, as the leases do not have readily determinable implicit discount rates. The Company’s incremental borrowing rate is the rate of interest that it would have to borrow on a collateralized basis over a similar term and amount in a similar economic environment to pay its lease obligations. The Company determines the incremental borrowing rates for its leases by adjusting the local risk-free interest rate with a credit risk premium corresponding to its credit rating. From time to time, the Company may enter into arrangements for the construction or purchase of an asset and then enter into a financing arrangement to lease the asset. The Company recognizes leased assets and liabilities under these arrangements when it obtain control of the asset.

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, zinc and lead. 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 particularly 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.
COVID-19	COVID-19 During the year ended December 31, 2021, the COVID-19 pandemic continued to impact global economic and financial markets, disrupting global supply chains and workforce participation. Many industries and businesses, including the Company, continue to be impacted by the COVID-19 pandemic and face operating challenges associated with the regulations and guidelines resulting from efforts to contain COVID-19. The Company continues to restrict all non-essential travel and manage the contacts of its employees and contractors in order to reduce the risk of COVID-19 impacting its operations. The Company is operating its corporate offices at reduced capacity, with most employees working remotely. The Company's mine sites remain operational with carefully managed COVID-19 based restrictions designed to protect communities and employees, including quarantining, testing, ensuring physical distancing and providing additional protective equipment.
Basis of preparation	Basis of preparation These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Previously, the Company prepared its consolidated financial statements under International Financial Reporting Standards ("IFRS") as permitted by securities regulators in Canada, as well as in the United States under the status of a Foreign Private Issuer as defined by the United States Securities and Exchange Commission ("SEC"). As of June 30, 2021, the Company determined that it no longer qualified as a Foreign Private Issuer under the SEC rules. As a result, beginning January 1, 2022 the Company is required to report with the SEC on domestic forms and comply with domestic company rules in the United States. The transition to U.S. GAAP was made retrospectively for all periods from the Company’s inception. New accounting standards implemented subsequent to January 1, 2019 were adopted on their required adoption date.
Use of estimates	Use of estimates Preparing financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management’s estimates and assumptions relate to mineral reserves that are the basis for future cash flow estimates utilized in impairment calculations and units-of-production depreciation; reclamation liabilities; valuation of assets acquired and liabilities assumed in business combinations; estimates of fair value for certain reporting units and asset impairments (including impairments of long-lived assets and goodwill); estimates of recoverable metal in stockpile and leach pad inventories; estimates of the net realizable value of inventory, stockpiles and ore on leach pads; and estimates of deferred tax assets and liabilities. The Company has based its estimates on historical experience and various other assumptions that it believes to be reasonable. Accordingly, actual results may differ materially from these estimates under different assumptions or conditions. Changes in facts and circumstances may alter such estimates and affect the results of operations and financial position in future periods.
Principles of consolidation	Principles of consolidationThese consolidated financial statements include the accounts of SSR Mining Inc., its wholly owned subsidiaries, and variable interest entities (“VIEs”) in which it is the primary beneficiary. Intercompany assets, liabilities, equity, income, expenses, and cash flows between SSR Mining Inc. and its subsidiaries have been eliminated on consolidation. Investments in joint ventures in which the Company has significant influence and VIEs where the Company is not the primary beneficiary are accounted for under the equity method of accounting.
Operating segments	Operating segments The Company has five reportable segments for financial reporting purposes: Çöpler, Marigold, Seabee, Puna and the exploration, evaluation and development properties. Çöpler, Marigold, Seabee and Puna segments represent the Company's four operating mine sites. The exploration, evaluation and development properties segment represents a portfolio of prospective exploration tenures, both near or adjacent to the existing operations (near-mine) and greenfield standalone prospects, across Turkey, the U.S., Canada, Mexico and Peru. For further information refer to Note 4.
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 independent 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.
Foreign currency transactions	Foreign currency transactions The functional and reporting currency of SSR Mining and each of its subsidiaries is the USD. Accordingly, foreign currency transactions and balances of the Company’s subsidiaries are remeasured as follows: (i) monetary assets and liabilities denominated in currencies other than the USD (“foreign currencies”) are remeasured into USD at the exchange rates prevailing at the balance sheet date; and (ii) non-monetary assets denominated in foreign currencies and measured at other than fair value are remeasured using the rates of exchange at the transaction date. Foreign exchange gains and losses are recognized in Foreign exchange gain (loss) in the Consolidated Statements of Operations. Unrealized foreign exchange gains and losses on cash and cash equivalent balances denominated in foreign currencies are disclosed separately in the Consolidated Statements of Cash Flows.
Cash and cash equivalents	Cash and cash equivalents Cash and cash equivalents include cash on hand and held at banks and short-term investments with an original maturity of three months or less, which are readily convertible into a known amount of cash. Restricted cash is presented separately in Restricted cash
Inventories	Inventories Stockpiled ore, leach pad inventory, work-in-process inventory, and finished goods are valued at the lower of average cost or net realizable value (“NRV”). NRV is calculated using the estimated price at the time of sale based on prevailing and forecasted metal prices, less estimated future production costs to convert the inventory into saleable form, depreciation, and all associated selling costs. Costs include all direct costs incurred in production, including direct labor and materials, freight, depletion and depreciation, and directly attributable overhead costs. Any write-downs of inventory to NRV are recognized within Production costs and Depreciation, depletion, and amortization in the Consolidated Statements of Operations. Stockpiled ore represents ore that has been extracted from the mine and is available for further processing. The cost of stockpiled ore is derived from the current mining costs incurred up to the point of stockpiling the ore and is removed at the weighted average cost as ore is processed. Quantities of stockpiled ore are verified by periodic surveys. Stockpiled ore that is not expected to be processed within the next twelve months is classified as non-current. Leach pad inventory represents ore that has been mined and placed on leach pads where a solution is applied to the surface of the heap to dissolve the gold and by-products. The resulting solution is further processed in a plant to recover the gold. The cost of leach pad inventory is derived from current mining and leaching costs and is removed as ounces of gold are recovered at the weighted average cost per recoverable ounce of gold on the leach pads. Estimates of recoverable gold in the leach pads are calculated based on the quantities of ore placed on the leach pads (measured tonnes added to the leach pads), the grade of ore placed on the leach pads (based on assay data), and an estimated recovery percentage (based on estimated recovery assumptions from the block model). The nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, estimates are refined based on actual results and engineering studies over time. The final recovery of gold from leach pads will not be known until the leaching process is concluded at the end of the mine life. Ore on leach pads that is not expected to be recovered within the next twelve months is classified as non-current. Work-in-process inventory represents material that is currently in the process of being converted to a saleable product, whether being processed in a mill or following recovery from a leach pad. Work-in-process inventory is determined based on assays of the material fed into the process and the projected recoveries of the respective processing plants. Work-in-process inventory is valued at the lower of average cost of the material fed into the process plus the in-process conversion costs, including applicable depreciation relating to the process facilities, or NRV. Finished goods inventory includes metal concentrates at site and in transit, doré at a site or a refinery, or gold bullion and are valued at the lower of the average cost of the respective in-process inventories incurred prior to the refining process, plus applicable refining costs, or NRV. Costs are transferred from finished goods inventory and recorded as Production costs and Depreciation, depletion and amortization in the Consolidated Statements of Operations upon sale.
Mineral properties, plant and equipment	Mineral properties, plant and equipment Mineral properties Mineral properties are capitalized at fair value at the acquisition date. Mineral properties may include mineral reserves, mineral resources and exploration potential. Mineral reserves represent the estimate of ore that can be economically and legally extracted from the Company's mining properties. Production stage mineral properties are operating properties that contain proven and probable reserves and are amortized using the units-of-production method based on the estimated recoverable ounces or pounds in proven and probable reserves. Development stage mineral properties are those under development that contain proven and probable reserves. Exploration stage mineral properties are those that potentially contain mineralized material, consisting of (i) areas adjacent to existing mineral resources and mineralization located within the immediate mine area; (ii) areas outside of immediate mine areas that are not part of mineral resources; and (iii) greenfield exploration potential that is not associated with any other production, development, or exploration stage property. Mineral properties in the development and exploration stage are not amortized until the property is converted to the production stage. Mineral exploration costs, including costs associated with prospecting, sampling, mapping, diamond drilling and other work involved in searching for mineral resources are charged to Exploration, evaluation and reclamation costs as incurred. Mine development Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, the removal of overburden to initially expose an ore body at open pit surface mines and the building of access ways, shafts, lateral access, drifts, ramps and other infrastructure at underground mines. Capitalization of mine development project costs that meet the definition of an asset begins once mineralization is classified as proven and probable reserves. Drilling and related costs are capitalized for an ore body where proven and probable reserves exist, and the activities are directed at obtaining additional information about the ore body or converting mineralized material to proven and probable reserves. All other drilling and related costs are expensed as incurred. Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of Production costs . The cost of removing overburden and waste materials to access the ore body at an open pit mine prior to the production phase are referred to as “pre-stripping costs.” Pre-stripping costs are capitalized during the development of an open pit mine. Where multiple open pits exist at a mining complex utilizing common processing facilities, pre-stripping costs are capitalized for each pit. The removal, production, and sale of de minimis saleable materials may occur during the development phase of an open pit mine and are assigned incremental mining costs related to the removal of that material. The production phase of an open pit mine commences when saleable minerals, beyond a de minimis amount, are produced. Stripping costs incurred during the production phase of a mine are variable production costs that are included as a component of inventory to be recognized in Production costs in the same period as the revenue from the sale of inventory. Mine development costs are amortized using the units-of-production method based on estimated recoverable ounces or pounds in proven and probable reserves. To the extent that these costs benefit an entire ore body, they are amortized over the estimated life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block or area. Plant and equipment Expenditures for new facilities or equipment and expenditures that extend the useful lives of existing facilities or equipment are capitalized and recorded at cost. Facilities and equipment acquired as part of a finance lease are capitalized and recorded as right-of-use ("ROU") assets based on the contractual lease terms. The carrying amounts of plant and equipment are depreciated to their estimated residual value over the estimated useful lives of the specific assets or the estimated life-of-mine ("LOM"), if shorter. Depreciation starts on the date when the asset is available for its intended use. Construction in process assets are not depreciated until available for their intended use. The major categories of plant and equipment are depreciated on a straight-line basis using the estimated lives indicated below: Vehicles 5 years - 7 years Mining equipment 3 years - 21 years Mobile equipment components 2 years - 7 years Buildings 5 years - 21 years Mine plant equipment 3 years - 21 years Underground infrastructure 5 years - 21 years ROU assets - plant and equipment (1) 10 years - 21 years
Impairment of long-lived assets	Impairment of long-lived assets The Company assesses the carrying value of its long-lived assets for impairment when events or changes in circumstances indicate that the related carrying amounts of such assets may not be recoverable. Events or circumstances that could indicate that the carrying value of an asset or asset group may not be recoverable include, but are not limited to, significant adverse changes in the business climate including changes in future metal prices, significant changes to the extent or manner in which the asset is being used or its physical condition including significant decreases in production or mineral reserves, and significant decreases in the market price of the assets. In evaluating long-lived assets for recoverability, estimates of undiscounted future cash flows of the Company's mines are used. An impairment is considered to exist if total estimated undiscounted future cash flows are less than the carrying amount of the asset. Once it is determined that an impairment exists, and impairment loss is recognized based on the difference between the estimated fair value of the long-lived assets and their carrying amounts. Fair value is typically determined through the use of an income approach utilizing estimates of discounted future cash flows. Future cash flows are derived from current business plans which are developed using short and long-term metal price assumptions; estimates of costs; and resource, reserve and exploration potential estimates, including timing and costs to develop and produce the material and are considered Level 3 fair value measurements. The Company believes its estimates and models used to determine fair value are similar to what a market participant would use.
Goodwill	Goodwill Under the acquisition method of accounting for business combinations, the identifiable assets acquired and liabilities assumed are recognized at their estimated fair value as of the date of acquisition. The excess of the fair value of consideration paid over the fair value of the identifiable net assets acquired is recognized as Goodwill and allocated to the reporting units.
Stock-based compensation	Stock-based compensation The Company determines the fair value on the grant date for stock-based compensation awards and expenses the awards in the Consolidated Statements of Operations over the vesting period on a straight-line basis. Based on the terms of the award, and the Company’s intent and past practice for settlement in cash or shares, the awards are classified as liabilities or equity. The Company recognizes forfeitures as they occur. Cash-settled stock-based compensation arrangements; including Deferred Share Units (“DSUs”), DSU Replacement Units, Performance Stock Units (“PSUs”), and PSU Replacement Units are remeasured at fair value at the end of each reporting period and at the date of settlement, with any changes in fair value recognized in profit or loss for the period.
Income taxes	Income taxes The income tax and mining expense for the period is comprised of current tax expense and deferred tax expense, and is recognized in the Consolidated Statements of Operations. Current income tax Current tax for each of the Company's taxable entities is based on the local taxable profit for the period at the local statutory tax rates enacted at the date of the Consolidated Balance Sheets as well as the available double tax treaty rates as ratified. Management periodically evaluates positions taken in tax returns in situations in which applicable tax regulation is subject to interpretation. The Company establishes provisions where appropriate on the basis of amounts expected to be paid to tax authorities. Any uncertain tax positions must meet a more-likely-than-not realization threshold to be recognized and any potential accrued interest and penalties related to unrecognized tax benefits are recognized within Income tax benefit (expense) . Deferred tax Deferred income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are determined by applying the enacted statutory tax rates in effect at the end of a reporting period to the cumulative temporary differences between the tax bases of assets and liabilities and their reported amounts in the Company’s consolidated financial statements. Deferred income tax assets are recognized for all deductible temporary differences to the extent that it is more likely than not that taxable profits will be available to be utilized against those deductible temporary differences. A valuation allowance for deferred tax assets is established when it is more likely than not that some portion of the benefit from deferred tax assets will not be realized. The extent to which deductible temporary differences, unused tax losses and other income tax deductions are expected to be realized are reassessed at the end of each reporting period. The effect on deferred taxes for a change in tax rates is recognized in income during the period that the enactment date is effective. Deferred tax assets are recognized for investment incentive tax credits in Turkey in the period earned as expenditures that are more likely than not to be accepted as eligible spend occur and it is more likely than not that taxable profits will be available to be utilized against those credits, which can be applied to current and future year income tax payments. The Company accounts for the investment incentive tax credit in Turkey using the flow-through method. Under this method, the investment incentive tax credit is treated as a reduction of income taxes in the year in which the credit arises. Deferred income tax liabilities are not recognized for taxable temporary differences associated with investments in subsidiaries and associates, and interests in joint ventures, unless it becomes apparent that the excess book over tax basis difference is expected to reverse in the foreseeable future. Accordingly, deferred income tax assets and liabilities are recognized for future withholding taxes payable where it has been determined that the amount would reasonably be payable in the foreseeable future. Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset the current tax assets against the current tax liabilities, when they relate to income taxes levied by the same taxation authority, and the Company intends to settle its current tax assets and liabilities on a net basis. Mining taxes and other tax arrangements Mining taxes or royalties and other arrangements are treated as taxation arrangements when they have the characteristics of an income tax. This is the case when they are imposed under government authority and the amount payable is calculated by reference to an income measure. Obligations arising from royalty arrangements that do not satisfy these criteria are recognized as current liabilities and included within Production costs .
Investments	Investments The Company has investments in debt securities and marketable equity securities. The Company determines the appropriate classification of debt securities at the time of purchase and re-evaluates such determinations at each reporting date. Current investments include marketable equity securities and held to maturity and available for sale debt securities. Marketable equity securities are carried at fair value. Held to maturity securities, classified based on the intent and ability to hold the securities to maturity, are carried at amortized cost. Marketable debt securities are categorized as available for sale and carried at fair value. Gains and losses on the sale of securities are recognized on a specific identification basis. Unrealized gains and losses are included in Other income (expense) on the Consolidated Statements of Operations.
Derivative financial instruments	Derivative financial instruments The Company is exposed to various market risks, including the effect of changes in metal prices and foreign exchange rates, and from time to time uses derivatives to manage financial exposures that occur in the normal course of business. The Company recognizes derivatives as either assets, presented in the Consolidated Balance Sheets in Prepaid and other current assets or Other non-current assets , or liabilities, presented in the Consolidated Balance Sheets in Accrued liabilities and other or Other non-current liabilities , and measures those instruments at fair value. These are considered Level 2 fair value measurements. Changes in the value of derivative instruments are recorded each period in Production Costs or Other income (expense)
Reclamation liabilities	Reclamation liabilities The Company recognizes a liability for the fair value of estimated future reclamation costs when incurred. The liability is accreted over time through periodic charges to Exploration, evaluation and reclamation costs in the Consolidated Statements of Operations. In addition, the asset retirement cost is capitalized as part of the asset's carrying value and amortized over the life of the related asset. Reclamation liabilities are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of reclamation costs. Changes in the estimate of reclamation costs may result from changes in legal or regulatory requirements, increased obligations arising from additional mining and exploration activities, and changes to cost estimates. Changes in reclamation estimates at mines that are not currently operating, as the mine or portion of the mine site has entered the closure phase and has no substantive future economic value, are reflected in Exploration, evaluation and reclamation costs in the Consolidated Statements of Operations. The estimated reclamation obligation is based on when spending for an existing disturbance is expected to occur. The Company reviews, on an annual basis, unless otherwise deemed necessary, the reclamation obligation at each mine site.
Leases	Leases The Company has entered into lease contracts under which it is the lessee. The Company determines whether an arrangement is, or contains, a lease based on the substance of the arrangement at its inception. If the contract is determined to be a lease, the Company classifies the lease as either an operating or financing lease. Operating lease right of use ("ROU") assets are included in Other non-current assets and lease obligations are included in Accrued liabilities and other and Other non-current liabilities in the Consolidated Balance Sheets. Finance lease ROU assets are included in Mineral properties, plant and equipment and lease obligations are included in Finance lease liabilities in the Consolidated Balance Sheets. ROU assets represent the Company’s right to use the underlying assets for the lease term and the corresponding lease liabilities represent its obligations to make lease payments arising from the leases. Operating and finance lease ROU assets and liabilities are recognized at the commencement date based on the present value of the expected lease payments over the lease term. When the rate of interest implicit in the lease cannot be readily determined, the Company uses its incremental borrowing rate in determining the present value of future lease payments. Operating lease costs are recognized on a straight-line basis over the lease term. Finance lease costs are recognized based on the effective interest method for the lease liability and straight-line amortization of the ROU asset, resulting in more cost being recognized in earlier periods. Variable lease payments are recognized in the period in which they are incurred. The Company has elected certain practical expedients including the short-term lease recognition exemption for all classes of underlying assets. Accordingly, leases with a term of one year or less have not and will not be recognized on the Consolidated Balance Sheets. The Company has also elected the practical expedient to not separate lease and non-lease components such as taxes and common area maintenance charges, in certain classes of assets such as its office facilities.
Revenue recognition	Revenue recognition The Company generates revenue by selling gold, copper, silver, lead and zinc produced from its mining operations. The majority of the Company’s sales come from the sale of refined gold bullion; however, the end product at the Company’s gold operations is generally doré bars. The Company also sells silver-lead and zinc concentrate to smelters for further treatment and refining. Gold sales Doré is sent to refiners to produce bullion that meets the required market standard of 99.95% gold. Under the terms of the Company’s refining agreements, the doré bars are refined for a fee, and the Company’s share of the refined gold and separately recovered silver is credited to its bullion account. Doré produced at Marigold and Seabee is sold primarily to bullion banks in the London spot market. Doré produced at Çöpler is sold primarily on the Istanbul Gold Exchange. Under legislation commenced in Turkey in 2018, the Central Bank of the Republic of Turkey has the first right of refusal for all gold produced by mining operations in Turkey. The Company generally recognizes revenue for gold from doré production when it satisfies the performance obligation of transferring gold bullion credits to the customer, as this is the point at which the customer obtains the ability to direct the use of and hold the remaining benefits of ownership of the asset. The transaction price is fixed on the date of sale based on the London Bullion Market Association's (“LBMA”) gold fix price or spot price and number of ounces delivered. Payment is due upon delivery of gold bullion credits to the customer’s account. Concentrate sales Metals produced at Puna are sold in concentrate form to smelters and traders. The Company recognizes revenue for silver-lead and zinc concentrate, net of treatment and refining costs, when it satisfies the performance obligation of transferring control of the concentrate to the customer. This generally occurs as material passes over the vessel’s rail at the port of loading or unloading, as the customer has the risk of loss and ability to direct the use of and obtain substantially all of the remaining benefits of the material. The Company has elected to account for shipping and handling costs for concentrate contracts as fulfillment activities and not as promised goods or services; therefore, these activities are not considered separate performance obligations. The initial sales price of concentrate metal sales is determined on a provisional basis at the date of sale as the final selling price is subject to movements in the monthly average London Metal Exchange (“LME”) or LBMA prices up to the date of final pricing. The period between provisional invoicing and final pricing, or settlement period, is typically between 30 and 120 days. The Company’s accounts receivable from 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 is adjusted to fair value through Revenue
Income per share	Income per shareBasic net income per share is calculated by dividing the net income or loss attributable to common stockholders of the Company by the weighted average number of common shares outstanding during the period. Diluted net income per share is determined by including the basic weighted average number of common shares outstanding adjusted for the effects of all potential dilutive shares of common stock, unless their effect would be anti-dilutive.
