Basis of Preparation of Financial Statements	1. 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. However, 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 do not necessarily indicate 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, 2023 included in the Company’s annual report on Form 10-K (the “2023 Annual Report”). 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 2023 Annual Report.

Income Taxes	5. Income Taxes The Company recorded an income tax benefit of $1.9 million for the three months ended March 31, 2024. For the three months ended March 31, 2023, the Company recorded an income tax benefit of $0.1 million. 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. Income in Mexico is taxed at 37.5% (30% income tax and 7.5% mining tax), and Canada’s 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: (i) 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, and (ii) the “extraordinary” mining duty of 0.5% on gross revenue from the sale of gold, silver, and platinum. The mining royalty tax generally applies to earnings before income tax, depreciation, depletion, amortization, and interest. In calculating the mining royalty tax, there are no corporate deductions related to depreciable costs from operational fixed assets. However, prospecting and exploration expenses are amortized using a 10% rate in a 10-year straight line. Both duties are tax deductible for income tax purposes. As a result, our effective tax rate applicable to the Company’s Mexican operations is higher than Mexico’s statutory rate. The Company periodically transfers funds from its Mexican wholly owned subsidiary to the U.S. as 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 specific 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 estimated annual effective tax rate reflects the impact of the planned annual dividends for 2023. As of March 31, 2024, the Company recorded a $0.1 million deferred tax liability related to the 5% withholding tax on funds available for transfer to the U.S. as dividends in the future are 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. In October 2023, the Company received a notification from the Mexican Tax Administration Services (“SAT”) with a sanction of 331 million pesos (approximately $19.9 million) as the result of a 2015 tax audit that began in 2021. The 2015 tax audit performed by SAT encompassed various tax aspects, including but not limited to intercompany transactions, mining royalty tax, and extraordinary mining tax. Management is in process of disputing this tax notification and sent a letter of protest to the tax authorities along with providing all requested documentation. Management intends to pursue legal avenues of protest, including filing a lawsuit with the Mexico court system, if necessary, to ensure that these adjustments are removed. Management believes the position taken on the 2015 income tax return meets the more likely than not threshold and that as of March 31, 2024 and December 31, 2023, the Company has no liability for uncertain tax positions. If the Company were to determine there was an unrecognized tax benefit, the Company would recognize the liability and related interest and penalties within income tax (benefit) provision.

Starting in the third quarter of each year, these same statutes allow companies to request a reduction of the coefficient, which adjusts for losses experienced in the current year. During 2023, DDGM had to prepay approximately $76 million pesos ($5 million) despite of the losses for the year. In 2024, these overpayments can be used to offset the required 2024 tax prepayments, and as a result, no income tax payments are expected in 2024. Other current assets A value added (“IVA”) tax in Mexico is assessed on the sales of products and purchases of materials and services. 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 March 31, 2024, this resulted in an asset balance of $0.3 million, included in Other current assets.

Gold and Silver Stream Agreements	10. Gold and Silver Stream Agreements The following table presents the Company’s liabilities related to the Company’s Gold and Silver Stream Agreements with Osisko Bermuda Limited (“OBL”), a wholly owned subsidiary of Osisko Gold Royalties Ltd (TSX & NYSE: OR), as of March 31, 2024 and December 31, 2023: As of As of March 31, December 31, 2024 2023 (in thousands) Liability related to the Gold Stream Agreement $ 21,553 $ 21,002 Liability related to the Silver Stream Agreement 24,788 23,930 Total liability $ 46,341 $ 44,932 Periodic interest expense is incurred based on an implied interest rate. The implied interest rate is determined based on the timing and probability of future production and a 6% discount rate. Interest expense is recorded to the Condensed Consolidated Statements of Operations and the gold and silver stream agreement liability on the Condensed Consolidated Interim Balance Sheets. The stream agreements contain customary provisions regarding default and security. In the event that our subsidiary defaults under the stream agreements, including by failing to achieve commercial production by an agreed upon date, it may be required to repay the deposit plus accumulated interest at a rate agreed with OBL. If the Company fails to do so, OBL may elect to enforce its remedies as a secured party and take possession of the assets that comprise the Back Forty Project. Gold Streaming Agreement In November 2017, Aquila entered into a stream agreement with OBL, 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 OBL, 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 March 31, 2024. In March 2024, the Company secured an amendment to the stream agreement that deferred the required completion of certain operational milestones related to permitting from 2024 to 2026. The $20 million received from OBL through March 31, 2024 is shown as a long-term liability on the Condensed Consolidated Interim Balance Sheets, along with an implied interest. The implied interest rate is applied on the OBL advance payments and calculated on the total expected life-of-mine production to be deliverable using an estimated gold price and a discount rate of 6%. As the remaining $30 million deposit is subject to the completion of specific milestones and the satisfaction of certain other conditions, this amount is not reflected on the Condensed Consolidated Interim Balance Sheets. 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 OBL. Please see Note 12—Commitments and Contingencies Item 1—Condensed Consolidated Interim Financial Statements and Notes (unaudited) . Silver Stream Agreement Through a series of contracts, Aquila executed a silver stream agreement with OBL to purchase 85% of the silver produced and sold at the Back Forty Project. A total of $17.2 million has been advanced under the agreement as of March 31, 2024. 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 March 31, 2024. In March 2024, the Company secured an amendment to the stream agreement that deferred the required completion of certain operational milestones related to permitting from 2024 to 2026. 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 March 31, 2024 is shown as a long-term liability on the Condensed Consolidated Interim Balance Sheets and includes an implied interest rate. The implied interest rate is applied on the OBL advance payments and calculated on the total expected life-of-mine production to be deliverable using an estimated silver price and a discount rate of 6%.

The Company’s undiscounted reclamation liabilities of $ 2.3 million and $2.2 million as of March 31, 2024 and December 31, 2023, respectively, are related to the Don David Gold Mine in Mexico. 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, and mine development. The Company’s asset retirement obligations reflect the additions to the asset for reclamation and remediation costs in Property, Plant, and Mine Development, post-2013 development stage status, which are discounted using a credit adjusted risk-free rate of 8%. As of March 31, 2024 and December 31, 2023, the Company’s asset retirement obligation was $9.9 million and $9.6 million, respectively, primarily related to the Don David Gold Mine in Mexico.

Commitments and Contingencies	12. Commitments and Contingencies Commitments As of March 31, 2024 and December 31, 2023, the Company has equipment purchase commitments of approximately $0.9 million and $0.8 million, respectively. Contingent Consideration With the Aquila acquisition, the Company assumed a contingent consideration. On December 30, 2013, Aquila’s shareholders approved the 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: The value of future installments is based on C$9 million tied to the 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; 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; a. C $2 million payable in cash 450 days after the commencement of commercial production. Initially, the Company intended to pay the first C$3 million in 2023 to prevent HudBay’s 51% buy-back option in the Back Forty Project. Management later decided that it was more likely than not that HudBay would not exercise its buy-back option, and consequently, this amount was not paid. Additionally, since financing of the project is not expected in 2024, this liability was reclassified to long-term. As of the end of January 2024, by the contractual deadline, HudBay did not exercise its buy-back option, and thus, it is forfeited. The total value of the contingent consideration as of March 31, 2024 and December 31, 2023 was $3.6 million and $3.5 million, respectively. The contingent consideration is adjusted for the time value of money and the likelihood of the milestone payments. Any future change in the value of the contingent consideration is recognized in other expense, net, in the Condensed Consolidated Statements of Operations. The following table shows the change in the balance of the contingent consideration for the three months ended March 31, 2024 and the year ended December 31, 2023: 2024 2023 (in thousands) Beginning Balance of contingent consideration: Current contingent consideration $ - $ 2,211 Non-current contingent consideration 3,548 2,179 $ 3,548 $ 4,390 Change in value - (2,211) Change in value 50 1,369 Ending Balance of contingent consideration: Current contingent consideration $ - $ - Non-current contingent consideration 3,598 3,548 $ 3,598 $ 3,548 Other Contingencies The Company has certain other contingencies resulting from litigation, claims, and other commitments and is subject to various environmental and safety laws and regulations incident to the ordinary course of business. The Company currently has no basis to conclude that any or all of 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. There can be no assurance that the ultimate disposition of contingencies will not have a material adverse effect on the Company’s financial position, results of operations, or cash flows. With the acquisition of Aquila Resources Inc. on December 10, 2021, the Company assumed substantial liabilities that relate to the gold and silver stream agreements with OBL. Under the agreements, OBL deposited a total of $37.2 million upfront in exchange for a portion of the future gold and silver production from the Back Forty Project. The stream agreements contain customary provisions regarding default and security. In the event that our subsidiary defaults under the stream agreements, including failing to achieve commercial production at a future date, it may be required to repay the deposit plus accumulated interest at a rate agreed with OBL. If it fails to do so, OBL may be entitled to enforce its remedies as a secured party and take possession of the assets that comprise the Back Forty Project.

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 allows eligible employees to make tax deferred contributions to a retirement trust account up to 90% of their qualified wages, subject to the IRS annual maximums. On April 23, 2021, a decree that reforms labor outsourcing in Mexico was published in the Federation’s Official Gazette. This decree amended the outsourcing provisions, whereby operating companies can no longer source their labor resources used to carry out the core business functions from service entities or third-party providers. Under Mexican law, employees are entitled to receive statutory profit sharing (Participacion a los Trabajadores de las Utilidades or “PTU”) payments. 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.

Net Loss per Common Share
Net Loss per Common Share	18. Net Loss 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 of the Company’s RSUs are anti-dilutive due to the Company’s net loss for the period. Since PSUs and DSUs are expected to be cash settled, they are not included in the dilutive calculation. 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 0.8 million shares of common stock at weighted average exercise price of $2.99 were outstanding as of March 31, 2024, but had no dilutive effect due to the net loss for the period. Options to purchase 1.5 million shares of common stock at a weighted average exercise price of $2.90 were outstanding as of March 31, 2023 but had no dilutive effect due to the net loss for the period.

Fair Value Measurement
Fair Value Measurement	19. 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 and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. These assets and liabilities are remeasured for each reporting period. The following tables set forth certain of the Company’s assets and liabilities measured at fair value by level within the fair value hierarchy as of March 31, 2024 and December 31, 2023: As of As of March 31, December 31, Input Hierarchy Level 2024 2023 (in thousands) Cash and cash equivalents $ 5,662 $ 6,254 Level 1 Accounts receivable, net $ 4,161 $ 4,335 Level 2 Investment in equity securities-Maritime $ 1,909 $ 1,596 Level 1 Investment in equity securities-Green Light Metals $ 3,618 $ 3,698 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: sales have not yet settled as of the reporting date, the mark-to-market adjustment related to these invoices is included in accounts receivable as of each reporting date.
