Basis of Preparation of Financial Statements ​ The Condensed Consolidated Interim Financial Statements (“interim financial statements”) of Gold Resource Corporation and its subsidiaries (collectively, the “Company”) are unaudited and have been prepared in accordance with the rules of the Securities and Exchange Commission (“SEC”) for interim statements. Certain information and footnote disclosures required by United States Generally Accepted Accounting Principles (“U.S. GAAP”) have been condensed or omitted as permitted by such rules, although the Company believes that the disclosures included are adequate to make the information presented not misleading. In the opinion of management, all adjustments (including normal recurring adjustments) and disclosures necessary for a fair presentation of these interim financial statements have been included. The results reported in these interim financial statements are not necessarily indicative of the results that may be reported for the entire year. These interim financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2021 included in the Company’s annual report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements. Unless otherwise noted, there have been no material changes to the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s annual report on Form 10-K. ​ Certain items in the prior period’s consolidated financial statements and notes have been reclassified to conform to the current presentation. These reclassifications had no effect on the reported results of operations. ​

Income Taxes

Income Taxes
Income Taxes	5. Income Taxes ​ The Company recorded an income tax benefit of $0.2 million and income tax expense $8.9 million, respectively, for the three and nine months ended September 30, 2022. For the three and nine months ended September 30, 2021, the Company recorded an income tax expense of $2.4 million and $6.7 million, respectively. In accordance with applicable accounting rules, the interim provision for taxes is calculated using the estimated consolidated annual effective tax rate. The consolidated effective tax rate is a function of the combined effective tax rates for the jurisdictions in which the Company operates. Variations in the relative proportions of jurisdictional income could result in fluctuations to the Company’s consolidated effective tax rate. At the federal level, the Company’s income in the U.S. is taxed at 21%, and a 5% withholding tax applies to dividends received from Mexico. The Mexico income is taxed at 37.5% (30% income tax and 7.5% mining tax), and Canada income is taxed at 26.5%, which results in a consolidated effective tax rate above statutory U.S. Federal rates. The U.S. and Canadian jurisdictions do not currently generate taxable income. ​ Mexico Mining Taxation ​ Mining entities in Mexico are subject to two mining duties in addition to the 30% Mexico corporate income tax. The first is a “special” mining duty of 7.5% of taxable income as defined under Mexican tax law (also referred to as “mining royalty tax”) on extraction activities performed by concession holders. The mining royalty tax is generally applicable to earnings before income tax, depreciation, depletion, amortization, and interest, and it is considered an income tax for purposes of financial reporting. The second is a 0.5% mining duty over sales of gold and silver, but this duty is not considered an income tax for financial reporting purposes and reported as production cost. Both duties are tax deductible for Mexico income tax purposes. ​ On January 1, 2022, the 2022 Tax Reform became effective in Mexico, which included several amendments to the Income Tax Law relevant to tax deductions. For 2022, a depreciation rate of 5% per year was established for construction of facilities, additions, repairs, improvements, adaptations, as well as any other construction performed in a mining lot, in accordance with Article 12 of the Mexican Mining Law. ​ The Company periodically transfers funds from its Mexican wholly-owned subsidiary to the U.S. in the form of dividends, which are subject to a 10% Mexico withholding tax, unless otherwise provided per a tax treaty. The current U.S.-Mexico tax treaty limits the dividend withholding tax between these countries to 5%, as long as certain requirements are met. Based on the Company’s understanding that it meets these requirements, the Company pays a 5% withholding tax on dividends paid from Mexico. The impact of the planned annual dividends for 2022 is reflected in the estimated annual effective tax rate. As of September 30, 2022, the Company recorded $0.8 million deferred tax liability related to the 5% withholding tax on funds available for transfer to the U.S. as dividends in the future and no longer deemed to be permanently reinvested in Mexico. If these funds are distributed to the U.S. from Mexico in the future, at that time they will be subject to the 5% dividend withholding tax payment upon distribution. ​ As of September 30, 2022, the Company believes that it has no liability for uncertain tax positions. ​

Promissory Note

Promissory Note.
Promissory Note	6. Promissory Note ​ A promissory note was acquired in the Aquila Resources, Inc. (“Aquila”) acquisition. In October 2021, Aquila sold its Wisconsin assets to Green Light Metals in return for a C$4.9 million ($3.9 million) promissory note. In June, an amended agreement was executed. Under the amended promissory note, Green Light Metals is to deliver C$4.9 million in Green Light Metal common shares once Green Light Metals goes public, or private shares of Green Light Metals at the maturity date of December 31, 2022, whichever occurs first. The shares are expected to represent approximately 20% to 28% of the total outstanding shares of Green Light Metals. Due to the short maturity of the promissory note, the carrying amount approximates the fair value, and likewise, no interest and collateral is required. Until maturity, the Company will record unrealized foreign currency gain or loss on the promissory note. ​

Businesses owe IVA taxes as the business sells a product and collects IVA taxes from its customers. Likewise, businesses are generally entitled to recover the taxes they have paid related to purchases of materials and services, either as a refund or credit to IVA tax payable. Amounts recorded as IVA taxes in the consolidated financial statements represent the net estimated IVA tax payable or receivable, since there is a legal right of offset of IVA taxes. As of September 30, 2022, this resulted in a small asset balance ($0.6 million), which is included in Other current assets above.

Gold and Silver Stream Agreements	10. Gold and Silver Stream Agreements ​ The following table presents the Company’s liabilities related to the Gold and Silver Stream Agreements as of September 30, 2022 and December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ As of ​ ​ September 30, ​ December 31, ​ ​ 2022 ​ 2021 ​ ​ (in thousands) Liability related to the Gold Stream Agreement ​ $ 20,506 ​ $ 20,364 Liability related to the Silver Stream Agreement ​ ​ 22,695 ​ ​ 22,196 Total liability ​ $ 43,201 ​ $ 42,560 ​ Periodic interest expense will be incurred based on an implied interest rate. The implied interest rate is determined based on the timing and probability of future production and an 8% discount rate. Interest expense is recorded to the Consolidated Statements of Operations and the gold and silver stream agreement liability on the Consolidated Balance Sheet. ​ Gold Streaming Agreement ​ In November 2017, Aquila entered into a stream agreement with Osisko Bermuda Limited (“OBL”), a wholly-owned subsidiary of Osisko Gold Royalties Ltd (TSX & NYSE: OR), pursuant to which OBL agreed to commit approximately $55 million to Aquila through a gold stream purchase agreement. In June 2020, Aquila amended its agreement with Osisko, reducing the total committed amount to $50 million, as well as adjusting certain milestone dates under the gold stream to align with the current project development timeline. Aquila had received a total of $20 million of the committed funds at the time of the Gold Resource Corporation acquisition. Remaining deposits from OBL are $5 million upon receipt of permits required for the development and operation of the Back Forty Project and $25 million upon the first drawdown of an appropriate project debt finance facility. OBL has been provided a general security agreement over the Back Forty Project which consists of the subsidiaries of Gold Resource Acquisition Sub, Inc., a 100% owned subsidiary of Gold Resource Corporation. The initial term of the agreement is for 40 years, automatically renewable for successive ten-year periods. The agreement is subject to certain operating and financial covenants, which are in good standing as of September 30, 2022. ​ The $20 million received from OBL through September 30, 2022 is shown as a long-term liability on the Consolidated Balance Sheet along with implied interest. The implied interest rate is applied on OBL advance payments and calculated on the total expected life-of-mine production to be deliverable (as supported in the Back Forty Project Preliminary Economic Assessment) at the five-year average street consensus metal prices (based on the median) evaluated as of December 31, 2021 and is discounted at 8.0%. As the remaining $30 million deposit is subject to the completion of certain milestones and the satisfaction of certain other conditions, this amount is not reflected on the Consolidated Balance Sheet. ​ Per the terms of the gold stream agreement, OBL will purchase 18.5% of the refined gold from Back Forty (the “Threshold Stream Percentage”) until the Company has delivered 105,000 ounces of gold (the “Production Threshold”). Upon satisfaction of the Production Threshold, the Threshold Stream Percentage will be reduced to 9.25% of the refined gold (the “Tail Stream”). In exchange for the refined gold delivered under the Stream Agreement, OBL will pay the Company ongoing payments equal to 30% of the spot price of gold on the day of delivery, subject to a maximum payment of $600 per ounce. Where the market price of gold is greater than the price paid, the difference realized from the sale of the gold will be applied against the deposit received from Osisko. ​ Silver Stream Agreement ​ Through a series of contracts, Aquila executed a silver stream agreement with OBL to purchase silver produced at the Back Forty Project. A total of $17.2 million has been advanced under the agreement as of September 30, 2022. There are no future deposits remaining under the agreement. The initial term of the agreement is for 40 years, automatically renewable for successive ten-year periods. The agreement is subject to certain operating and financial covenants, which are in good standing as of September 30, 2022. ​ Per the terms of the silver stream agreement, OBL will purchase 85% of the silver produced from the Back Forty Project at a fixed price of $4 per ounce of silver. Where the market price of silver is greater than $4 per ounce, the difference realized from the sale of the silver will be applied against the deposit received from Osisko. ​ The $17.2 million received from OBL through September 30, 2022 is shown as a long-term liability on the Consolidated Balance Sheet along with an implied interest.

These represent reclamation liabilities that were expensed through 2013 before proven and probable reserves were established and the Company was considered to be a development stage entity; therefore, most of the costs, including asset retirement costs, were not allowed to be capitalized as part of our Property, Plant & Mine Development. ​ The Company’s asset retirement obligations reflect the additions to the asset for reclamation and remediation costs in Property, Plant & Mine Development, post 2013 development stage status, which are discounted using a credit adjusted risk-free rate of 8%. As of September 30, 2022 and December 31, 2021, the Company’s asset retirement obligation related to the Don David Gold Mine in Mexico was $1.4 million and $1.3 million, respectively.

Commitments and Contingencies	12. Commitments and Contingencies ​ Commitments ​ As of September 30, 2022 and December 31, 2021, the Company has equipment purchase commitments of approximately $1.2 million and $0.4 million, respectively. ​ Contingent Consideration ​ With the Aquila acquisition, the Company assumed a contingent consideration related to the December 30, 2013, Aquila acquisition of 100% of the shares of HudBay Michigan Inc. (“HMI”), a subsidiary of HudBay Minerals Inc. (“HudBay”), effectively giving Aquila 100% ownership in the Back Forty Project (the “HMI Acquisition”). Pursuant to the HMI Acquisition, HudBay’s 51% interest in the Back Forty Project was acquired in consideration for the issuance of common shares of Aquila, future milestone payments tied to the development of the Back Forty Project, and a 1% net smelter return royalty on production from certain land parcels in the project. The issuance of shares and 1% net smelter obligations were settled before the Company acquired Aquila. ​ The contingent consideration is composed of the following in Canadian dollars: ​ The value of future installments is based on C$9 million tied to development of the Back Forty project as follows: a. C $3 million payable on completion of any form of financing for purposes including the commencement of construction of Back Forty. Up to 50% of the C $3 million can be paid, at the Company’s option, in Gold Resource Corporation shares with the balance payable in cash (if as of November 2023 this milestone has not been achieved or payment made, HMI has the right to repurchase a 51% ownership in the Back Forty Project); b. C $2 million payable in cash 90 days after the commencement of commercial production; c. C $2 million payable in cash 270 days after the commencement of commercial production; and d. C $2 million payable in cash 450 days after the commencement of commercial production. ​ The value of the contingent consideration as of September 30, 2022 was $4.0 million. The contingent consideration will be adjusted for the foreign currency translation, time value of money, and the likelihood of the milestone payments. Any future changes in the value of the contingent consideration will be recognized in the Consolidated Statements of Operations. ​ Other Contingencies ​ The Company has certain other contingencies resulting from litigation, claims, and other commitments that are subject to a variety of environmental and safety laws and regulations incidents related to the ordinary course of business. The Company currently has no basis to conclude that any or all such contingencies will materially affect its financial position, results of operations, or cash flows. However, in the future, there may be changes to these contingencies, or additional contingencies may occur, any of which might result in an accrual or a change in current accruals recorded by the Company, and there can be no assurance that their ultimate disposition will not have a material adverse effect on the Company’s financial position, results of operations, or cash flows. ​ With the successful acquisition of Aquila Resources Inc. on December 10, 2021, the Company assumed substantial liabilities that relate to the gold and silver stream agreements with Osisko Bermuda Limited (see Note 10 - Gold and Silver Stream Agreements at a rate agreed with Osisko. If it fails to do so, Osisko may be entitled to enforce their remedies as a secured party and take possession of the assets that comprise the Back Forty Project. ​ ​

Derivatives	14. Derivatives ​ Embedded Derivatives ​ Concentrate sales contracts contain embedded derivatives due to the provisional pricing terms for unsettled shipments. At the end of each reporting period, the Company records an adjustment to accounts receivable and revenue to reflect the mark-to-market adjustments for outstanding provisional invoices based on forward metal prices. Please see Note—20 Fair Value Measurement ​ The following table summarizes the Company’s unsettled sales contracts at September 30, 2022 with the quantities of metals under contract subject to final pricing occurring through November 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gold ​ Silver ​ Copper ​ Lead ​ Zinc ​ ​ Total ​ ​ (ounces) ​ (ounces) ​ (tonnes) ​ (tonnes) ​ (tonnes) ​ ​ ​ Under contract ​ ​ 4,784 ​ ​ 253,342 ​ ​ 282 ​ ​ 1,647 ​ ​ 3,373 ​ ​ ​ Average forward price (per ounce or tonne) ​ $ 1,741 ​ $ 19.52 ​ $ 7,738 ​ $ 2,011 ​ $ 3,474 ​ ​ ​ Unsettled sales contracts value (in thousands) ​ $ 8,329 ​ $ 4,945 ​ $ 2,182 ​ $ 3,312 ​ $ 11,718 ​ $ 30,486 ​ Other Derivatives ​ Derivative instruments that are not designated as hedging instruments are required to be recorded on the balance sheet at fair value. Changes in fair value will impact the Company’s earnings through mark-to-market adjustments until the physical commodity is delivered or the financial instrument is settled. The fair value does not reflect the realized or cash value of the instrument. ​ As of September 30, 2022, the Company’s derivatives not designated as hedges consist of zinc zero cost collars used to manage its near-term exposure to cash flow variability from zinc price risks. A zero cost collar is a combination of two options: a sold call option and a purchased put option. The Company sold call options to establish the ceiling price of $3,500 per tonne of zinc that the Company will receive for the contracted zinc volume of 1,950 tonnes for October through December 2022. The purchased put establishes the floor price of $3,200 per tonne of zinc that the Company will receive for the same contracted tonnes and period of time. ​ Derivatives are carried at fair value and on a net basis when a legal right of offset exists with the same counterparty. Otherwise, any fair value gains or losses are recognized in earnings in the current period. The London Metal Exchange (“LME”) average zinc price of $3,660 per tonne during the nine months ended September 30, 2022 exceeded the call option ceiling of $3,313 per tonne, resulting in a realized loss of $2.4 million. The zinc price forward curve as of September 30, 2022 is below the put option ceiling, resulting in a $0.4 million asset on the remaining 1,950 tonnes. The asset recognized resulted in an unrealized gain of $2.3 million for the nine months ended September 30, 2022. ​ The Company manages credit risk by selecting counterparties believed to be financially strong, by entering into netting arrangements with counterparties and by requiring other credit risk mitigants, as appropriate. The Company actively evaluates the creditworthiness of its counterparties, assigns appropriate credit limits, and monitors credit exposures against those assigned limits.

Employee Benefits
Employee Benefits	15. Employee Benefits ​ Effective October 2012, the Company adopted a profit sharing plan (the “Plan”) which covers all U.S. employees. The Plan meets the requirements of a qualified retirement plan pursuant to the provisions of Section 401(k) of the Internal Revenue Code. The Plan also provides eligible employees the opportunity to make tax deferred contributions to a retirement trust account up to 50% of their qualified wages, subject to the IRS annual maximums. ​ Under Mexican law, employees are entitled to receive statutory profit sharing (Participacion a los Trabajadores de las Utilidades or “PTU”) payment. The required cash payment to employees in the aggregate is equal to 10% of their employer’s profit subject to PTU, which differs from profit determined under U.S. GAAP.

Stock-Based Compensation
Stock-Based Compensation	16. Stock-Based Compensation ​ The Company’s compensation program comprises three main elements: base salary, an annual short-term incentive plan (“STIP”) cash award, and long-term equity-based incentive compensation (“LTIP”) in the form of performance share units (“PSUs”), restricted stock units (“RSUs”), stock options, and deferred stock units (“DSUs”). ​ The Gold Resource Corporation 2016 Equity Incentive Plan (the “Incentive Plan”) allows for the issuance of up to 5 million shares of common stock in the form of incentive and non-qualified stock options, stock appreciation rights, RSUs, stock grants, stock units, performance shares, performance share units, and performance cash. Additionally, pursuant to the terms of the Incentive Plan, any award outstanding under the prior plan that is terminated, expired, forfeited, or canceled for any reason, will be available for grant under the Incentive Plan. ​ Effective January 1, 2021, the Company’s Board of Directors, on the recommendation of the Compensation Committee, implemented a program to issue DSUs. DSUs are qualifying instruments under the terms of the Company’s Incentive Plan and therefore do not require additional shareholder approval. The vesting and settlement terms of the DSUs are determined by the Compensation Committee at the time the DSUs are awarded. ​ DSUs of nil and 214,357 were granted to the Board of Directors during the three and nine months ended September 30, 2022, respectively. DSUs of nil and 130,000 were granted to the Board of Directors during the three and nine months ended September 30, 2021, respectively. DSUs are redeemable in cash or shares at the earlier of 10 years or upon the eligible directors’ termination. Termination is deemed to occur on the earliest of (1) the date of voluntary resignation or retirement of the director from the Board; (2) the date of death of the director; or (3) the date of removal of the director from the Board whether by shareholder resolution, failure to achieve re-election, or otherwise; and on which date the director is not a director or employee of the Company or any of its affiliates. These awards contain a cash settlement feature and are therefore classified as a liability and are marked to fair value each reporting period. The Company may also issue DSUs for directors in lieu of board fees at their request. During the three and nine months ended September 30, 2022, respectively, there were 3,746 and 10,454 DSUs granted in lieu of board fees that are also subject to mark-to-market adjustment. Both during the three and nine months ended September 30, 2021, respectively, there were 1,960 DSUs granted in lieu of board fees that are also subject to mark-to-market adjustment. As of September 30, 2022 and 2021, the liability balance related to DSUs was $0.6 million and $0.2 million, respectively. ​ RSUs of nil and 611,681 were granted during the three and nine months ended September 30, 2022, respectively. No RSUs were granted during the three and nine months ended September 30, 2021. During the three and nine months ended September 30, 2022, a total of 41,666 and 119,467 RSUs vested, respectively, from which 41,666 and 80,169 RSUs were redeemed, respectively, issuing 41,666 and 75,584 common shares with an intrinsic value and a fair value of $74,165 and $138,101, respectively. During the three and nine months ended September 30, 2021, respectively, a total of 50,183 and 52,797 RSUs vested and redeemed, and 49,755 and 52,369 common shares were issued with an intrinsic value and a fair value of $0.1 million and $0.1 million, respectively. ​ Stock options of nil and 320,816 were granted during the three and nine months ended September 30, 2022, respectively. Stock options of nil and 600,000 were granted during the three and nine months ended September 30, 2021, respectively. Stock options of nil and 355,000, respectively, were exercised during the three and nine months ended September 30, 2022. These exercises were settled in cash. No stock options were exercised during the three months ended September 30, 2021. During the nine months ended September 30, 2021, stock options to purchase an aggregate of 217,718 shares of the Company’s common stock were exercised at a weighted average exercise price of $1.31 per share. ​ PSUs of nil and 695,041 were granted during the three and nine months ended September 30, 2022, respectively. No PSUs were granted during the three and nine months ended September 30, 2021.

Net Income per Common Share
Net Income per Common Share	19. Net Income per Common Share ​ Basic net income per common share is calculated based on the weighted average number of common shares outstanding for the period. Diluted earnings per common share are calculated based on the assumption that stock options and other dilutive securities outstanding, which have an exercise price less than the average market price of the Company’s common shares during the period, would have been exercised on the later of the beginning of the period or the date granted and that the funds obtained from the exercise were used to purchase common shares at the average market price during the period. All the Company’s RSUs and DSUs are considered to be dilutive in periods with net income. ​ The effect of the Company’s dilutive securities is calculated using the treasury stock method and only those instruments that result in a reduction in net income per common share are included in the calculation. Options to purchase 2.1 million shares of common stock at weighted average exercise prices of $3.52 and 2.1 million shares of common stock at weighted average exercise prices of and $5.11 were outstanding as of September 30, 2022 and 2021, respectively, but were not included in the computation of diluted weighted average common shares outstanding, as the exercise price of the options exceeded the average price of the Company’s common stock during the reporting period, and therefore are anti-dilutive. ​ Basic and diluted net income per common share is calculated as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended ​ For the nine months ended ​ ​ September 30, ​ September 30, ​ ​ 2022 ​ 2021 ​ 2022 ​ 2021 Numerator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income (in thousands) ​ $ (9,730) ​ $ 1,529 ​ $ (3,038) ​ $ 5,339 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Denominator: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic weighted average shares of common stock outstanding ​ ​ 88,391,220 ​ ​ 74,552,545 ​ ​ 88,358,188 ​ ​ 74,481,281 Dilutive effect of share-based awards ​ ​ - ​ ​ 345,975 ​ ​ - ​ ​ 360,814 Diluted weighted average common shares outstanding ​ ​ 88,391,220 ​ ​ 74,898,520 ​ ​ 88,358,188 ​ ​ 74,842,095 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted net (loss) income per common share ​ $ (0.11) ​ $ 0.02 ​ $ (0.03) ​ $ 0.07 ​

Fair Value Measurement
Fair Value Measurement	20. Fair Value Measurement ​ 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, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; 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 are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth certain of the Company’s assets measured at fair value on a recurring basis by level within the fair value hierarchy as of September 30, 2022 and December 31, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of ​ As of ​ ​ ​ ​ September 30, ​ December 31, ​ Input Hierarchy Level ​ ​ 2022 ​ 2021 ​ ​ ​ ​ (in thousands) ​ ​ Cash and cash equivalents ​ $ 22,531 ​ $ 33,712 ​ Level 1 Accounts receivable, net ​ $ 3,741 ​ $ 8,672 ​ Level 2 Investment in equity securities ​ $ 1,716 ​ $ - ​ Level 1 Derivative asset - zinc zero cost collar ​ $ 432 ​ $ - ​ Level 2 Derivative liability - zinc zero cost collar ​ $ - ​ $ (1,844) ​ Level 2 Contingent consideration ​ $ (4,036) ​ $ (4,603) ​ Level 3 Gold and silver stream agreements ​ $ (43,201) ​ $ (42,560) ​ Level 3 ​ The following methods and assumptions were used to estimate the fair value of each class of financial instrument: ​ Cash and cash equivalents ​ Accounts receivable, net: Note 14—Derivatives ​ Investment in equity securities Derivative liability - zinc zero cost collar For the zinc zero cost collar, when the prior month LME average zinc price is greater than the call price, positions settling in the period are recorded as a realized gain or loss, and unsettled positions are recorded as an unrealized gain or loss. ​ Contingent consideration Note 12— Commitments and Contingencies ​ Gold and silver stream agreements Note 10—Gold and Silver Stream Agreements ​ Gains and losses related to changes in the fair value of these financial instruments were included in the Company’s Condensed Consolidated Interim Statements of Operations as shown in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the three months ended September 30, ​ For the nine months ended September 30, ​ Statements of Operations Classification ​ ​ 2022 ​ 2021 ​ ​ 2022 ​ 2021 ​ ​ ​ Note (in thousands) ​ ​ Realized and unrealized derivative (loss) gain, net 14 $ (934) ​ $ (478) ​ ​ $ (1,064) ​ $ 156 ​ Sales, net Realized gain (loss) on zinc zero cost collar 17 $ 61 ​ $ (40) ​ ​ $ (2,396) ​ $ (40) ​ Realized and unrealized loss on zinc zero cost collar Unrealized gain (loss) on zinc zero cost collar 17 $ 157 ​ $ (144) ​ ​ $ 2,276 ​ $ (144) ​ Realized and unrealized loss on zinc zero cost collar ​ Realized/Unrealized Derivatives ​ The following tables summarize the Company’s realized/unrealized derivatives for the periods presented (in thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gold ​ Silver ​ Copper ​ Lead ​ Zinc ​ Total For the three months ended September 30, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Realized loss ​ $ (198) ​ $ (141) ​ $ (158) ​ $ (88) ​ $ (627) ​ $ (1,212) Unrealized (loss) gain ​ ​ (95) ​ ​ (81) ​ ​ 108 ​ ​ 96 ​ ​ 250 ​ ​ 278 Total realized/unrealized derivatives, net ​ $ (293) ​ $ (222) ​ $ (50) ​ $ 8 ​ $ (377) ​ $ (934) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gold ​ Silver ​ Copper ​ Lead ​ Zinc ​ Total For the three months ended September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Realized (loss) gain ​ $ (110) ​ $ (295) ​ $ (4) ​ $ 72 ​ $ 91 ​ $ (246) Unrealized gain (loss) ​ ​ 28 ​ ​ (11) ​ ​ (16) ​ ​ (84) ​ ​ (149) ​ ​ (232) Total realized/unrealized derivatives, net ​ $ (82) ​ $ (306) ​ $ (20) ​ $ (12) ​ $ (58) ​ $ (478) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gold ​ Silver ​ Copper ​ Lead ​ Zinc ​ Total For the nine months ended September 30, 2022 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Realized (loss) gain ​ $ (16) ​ $ 13 ​ $ (173) ​ $ (32) ​ $ 1,022 ​ $ 814 Unrealized (loss) gain ​ ​ (96) ​ ​ 30 ​ ​ 3 ​ ​ (103) ​ ​ (1,712) ​ ​ (1,878) Total realized/unrealized derivatives, net ​ $ (112) ​ $ 43 ​ $ (170) ​ $ (135) ​ $ (690) ​ $ (1,064) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gold ​ Silver ​ Copper ​ Lead ​ Zinc ​ Total For the nine months ended September 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Realized (loss) gain ​ $ (133) ​ $ (123) ​ $ 63 ​ $ 146 ​ $ 251 ​ $ 204 Unrealized gain (loss) ​ ​ 58 ​ ​ 10 ​ ​ (24) ​ ​ (63) ​ ​ (29) ​ ​ (48) Total realized/unrealized derivatives, net ​ $ (75) ​ $ (113) ​ $ 39 ​ $ 83 ​ $ 222 ​ $ 156 ​
