Basis of Preparation of Financial Statements and Nature of Operations	'
	1.   Basis of Preparation of Financial Statements and Nature of Operations
	Golden Minerals Company (the “Company”), a Delaware corporation, has prepared these unaudited interim condensed consolidated financial statements in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Such rules and regulations allow the omission of certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), so long as such omissions do not render the financial statements misleading.  The year-end balance sheet data was derived from audited financial statements, but does not include all disclosures normally required by GAAP.
	In the opinion of management, these financial statements reflect all adjustments that are necessary for a fair presentation of the financial results for the periods presented. These interim financial statements should be read in conjunction with the annual financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2013, and filed with the SEC on February 28, 2014.
	In June 2013 the Company suspended mining and processing at its Velardeña and Chicago precious metals mining properties (the “Velardeña Properties”) in Mexico in order to conserve the asset until the Company was able to create new mining and processing plans that, at then current prices for silver and gold, indicated a sustainable cash margin.  On June 18, 2014 the Company announced it would restart mining at the Velardeña Properties beginning in July 2014.  On July 11, 2014 the Company announced that it had restarted mining at its Velardeña Properties on July 1, 2014, with plans to begin processing material from the mine in the fourth quarter of 2014.   The Company is primarily focused on its activities to restart mining and processing at the Velardeña Properties and continued exploration of properties in Mexico. The Company is also reviewing strategic opportunities, focusing primarily on development or operating properties in North America, including Mexico.
	The Company is considered an exploration stage company under the criteria set forth by the SEC as the Company has not yet demonstrated the existence of proven or probable reserves, as defined by the SEC Industry Guide 7, at the Velardeña Properties, or any of the Company’s other properties.  As a result, and in accordance with GAAP for exploration stage companies, all expenditures for exploration and evaluation of the Company’s properties are expensed as incurred. As such the Company’s financial statements may not be comparable to the financial statements of mining companies that do have proven and probable reserves.
	The financial statements have been prepared on a going concern basis under which an entity is considered to be able to realize its assets and satisfy its liabilities in the normal course of business.  However, the continuing operations of the Company are dependent upon its ability to secure sufficient funding and to generate future profitable operations.  The underlying value and recoverability of the amounts shown as mineral properties in the condensed consolidated balance sheets are dependent on the ability of the Company to generate positive cash flows from operations and to continue to fund exploration and development activities that would lead to profitable mining activities or proceeds from the disposition of the mineral properties.  There can be no assurance that the Company will be successful in generating future profitable operations or securing additional funding in the future on terms acceptable to the Company or at all.

	2.   New Accounting Pronouncements
	On May 28, 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”). ASU 2014-09 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. In addition, the guidance requires improved disclosures to help users of financial statements better understand the nature, amount, timing and uncertainty of revenue that is recognized and the related cash flows. ASU 2014-09 is effective for interim and annual periods beginning after December 15, 2016; early application is not permitted. The Company is evaluating the financial statement implications of adopting ASU 2014-09 but does not believe adoption of ASU 2014-09 will have a material impact on the its consolidated financial position or results of operations.
	In April 2014 the FASB issued Accounting Standards Update No. 2014-08 “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity” (“ASU 2014-08)”. ASU 2014-08 changes the criteria for reporting discontinued operations while enhancing disclosures in this area. Under ASU 2014-08, only disposals representing a strategic shift in operations will be presented as discontinued operations. Additionally, ASU 2014-08 requires expanded disclosures about discontinued operations that will provide financial statement users with more information about the assets, liabilities, income, and expenses of discontinued operations. ASU 2014-08 will become effective for the Company in the first quarter of 2015. The Company does not believe the adoption of ASU 2014-08 will have a material impact on the Company’s consolidated financial position or results of operations.
	In July 2013 the FASB issued Accounting Standards Update No. 2013-11 “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”), which requires an unrecognized tax benefit to be presented as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward that the entity intends to use and is available for settlement at the reporting date. ASU 2013-11 became effective for the Company in the first quarter of 2014. The adoption of ASU 2013-11 has not had a material impact on the Company’s consolidated financial position or results of operations.

	The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Short-term investments include investments with maturities greater than three months, but not exceeding 12 months, or highly liquid investments with maturities greater than 12 months that the Company intends to liquidate during the next 12 months for working capital needs.
	The Company determines the appropriate classification of its investments in equity securities at the time of purchase and re-evaluates those classifications at each balance sheet date.  Available for sale investments are marked to market at each reporting period with changes in fair value recorded as a component of other comprehensive income (loss). If declines in fair value are deemed other than temporary, a charge is made to net income (loss) for the period.
	The Company had no short-term investments as of June 30, 2014 or December 31, 2013.

	The Company has recorded value added tax (“VAT”) paid in Mexico and related to the Velardeña Properties as a recoverable asset. Mexican tax law allows for certain VAT payments to be recovered through ongoing applications for refunds. The Company expects that the current amounts will be recovered within a one year period.
	The Company has also paid VAT in Mexico as well as other countries, primarily related to exploration projects, which has been charged to expense as incurred because of the uncertainty of recoverability.

	Key Employee Long-Term Incentive Plan
	On December 13, 2013, the Board of Directors of the Company approved and the Company adopted the 2013 Key Employee Long-Term Incentive Plan (the “KELTIP”), which became effective immediately. The KELTIP provides for the grant of units (“KELTIP Units”) to certain officers and key employees of the Company, which units will, once vested, entitle such officers and employees to receive an amount, in cash or in Company common stock issued pursuant to the Company’s Amended and Restated 2009 Equity Incentive Plan, measured generally by the price of the Company’s common stock on the settlement date. KELTIP Units are not an actual equity interest in the Company and are solely unfunded and unsecured obligations of the Company that are not transferable and do not provide the holder with any stockholder rights. Payment of the settlement amount of vested KELTIP Units is deferred generally until the earlier of a change of control of the Company or the date the grantee ceases to serve as an officer or employee of the Company.
	The KELTIP Units are marked to market at each reporting period. At June 30, 2014 and December 31, 2013 the Company had recorded liabilities of $198,000 and $81,000, respectively related to KELTIP Unit grants which are included in accrued employee compensation and benefits in the table above.

	9.   Asset Retirement Obligations
	The Company retained the services of a mining engineering firm to prepare a detailed closure plan for the Velardeña Properties. The plan was completed during the second quarter 2012 and indicated that the Company had an ARO and offsetting ARC of approximately $1.9 million. The estimated $3.5 million ARO and ARC that was recorded at the time of the acquisition of the Velardeña Properties was adjusted accordingly.
	The Company will continue to accrue additional estimated ARO amounts based on an asset retirement plan as activities requiring future reclamation and remediation occur.  During the first six months of 2014 the Company recognized approximately $0.1 million of accretion expense and approximately $0.1 million of amortization expense related to the ARC.
	The following table summarizes activity in the Velardeña Properties ARO:
		Six Months Ended

	Changes in estimates, and other	(85		)	203
	Accretion expense	98			88
	Ending balance	$	2,480		$	2,371
	The decrease in the ARO recorded during the six months ended June 30, 2014 is the result of changes in assumptions related to inflation factors and discount rates used in the determination of future cash flows.
	The increase in ARO recorded during the six months ended June 30, 2013 relates to a change in assumption related to inflation factors used in the determination of future cash flows.  The corresponding increase in ARO was discounted using the Company’s current credit-adjusted risk-free interest rate.
	The ARO set forth on the accompanying Condensed Consolidated Balance Sheets at June 30, 2014 and December 31, 2013 include approximately $0.1 million of reclamation liabilities related to activities at the El Quevar project in Argentina.

	11.   Fair Value Measurements
	The Company follows the guidance of ASC Topic 820 “Fair Value Measurements and Disclosures” (“ASC 820”) for financial assets and liabilities and nonfinancial assets and liabilities which are measured at fair value on a recurring basis.  ASC 820 establishes a framework for measuring fair value in the form of a fair value hierarchy which prioritizes the inputs into valuation techniques used to measure fair value into three broad levels.  This hierarchy gives the highest priority to quoted prices (unadjusted) in active markets and the lowest priority to unobservable inputs.  Further, financial assets and liabilities should be classified by level in their entirety based upon the lowest level of input that was significant to the fair value measurement.  The three levels of the fair value hierarchy per ASC 820 are as follows:
	Level 1:  Unadjusted quoted market prices in active markets for identical assets or liabilities that are accessible at the measurement date.
	Level 2:  Quoted prices in inactive markets for identical assets or liabilities, quoted prices for similar assets or liabilities in active markets, or other observable inputs either directly related to the asset or liability or derived principally from corroborated observable market data.
	Level 3:  Unobservable inputs due to the fact that there is little or no market activity. This entails using assumptions in models which estimate what market participants would use in pricing the asset or liability.
	The following table summarizes the Company’s financial assets and liabilities at fair value at June 30, 2014 and December 31, 2013, by respective level of the fair value hierarchy:
		Level 1		Level 2		Level 3		Total
		(in thousands)
	At June 30, 2014

	Liabilities:
	KELTIP payable	81		—				81
		$	10,344	$	—	$	—	$	10,344
	The Company’s cash equivalents, comprised principally of U.S. treasury securities, are classified within Level 1 of the fair value hierarchy.
	The KELTIP payable are related to employee and officer compensation as discussed in Note 8 and are marked to market at the end of each period based on the closing price of the Company’s common stock resulting in a classification of Level 1 within the fair value hierarchy.
	During the six months ended June 30, 2014 and for the year ended December 31, 2013 there were no amounts transferred between levels and there were no changes in fair value measurement techniques.  The Company did not have any Level 2 or Level 3 financial assets or liabilities at June 30, 2014 or December 31, 2013.
	Credit Risk
	Credit risk is the risk that a third party might fail to fulfill its performance obligations under the terms of a financial instrument. For cash and cash equivalents and investments, the Company’s maximum exposure to credit risk represents the carrying amount on the balance sheet. The Company attempts to mitigate credit risk for cash and cash equivalents by placing its funds with high credit-quality financial institutions, limiting the amount of exposure to each financial institution, monitoring the financial condition of the financial institutions and investing only in government and corporate securities rated “investment grade” or better. The Company invests with financial institutions that maintain a net worth of not less than $1.0 billion and are members in good standing of the Securities Investor Protection Corporation.

	The Company accounts for income taxes in accordance with the provisions of ASC 740, “Income Taxes” (“ASC 740”), on a tax jurisdictional basis.  For the six months ended June 30, 2014, the Company had no income tax benefit or expense.  The Company operates in jurisdictions that have generated ordinary losses on a year-to-date basis and no benefit can be recognized on those losses, thus an estimated effective tax rate is not used to report the year-to-date results.  For the six months ended June 30, 2013, the Company recorded a $47.5 million income tax benefit related primarily to the impairment of long lived assets of the Velardeña Properties and Mexico net operating losses, resulting in an elimination of the net deferred tax liability in existence at that time.
	In accordance with ASC 740, the Company presents deferred tax assets net of its deferred tax liabilities on a tax jurisdictional basis on its Consolidated Balance Sheets.  As of June 30, 2014 and as of December 31, 2013, the Company had no net deferred tax assets or net deferred tax liabilities reported on its balance sheet.
	The Company, a Delaware corporation, and its subsidiaries file tax returns in the United States and in various foreign jurisdictions.  The tax rules and regulations in these countries are highly complex and subject to interpretation. The Company’s income tax returns are subject to examination by the relevant taxing authorities and in connection with such examinations, disputes can arise with the taxing authorities over the interpretation or application of certain tax rules within the country involved.  In accordance with ASC 740, the Company identifies and evaluates uncertain tax positions, and recognizes the impact of uncertain tax positions for which there is less than a more-likely-than-not probability of the position being upheld upon review by the relevant taxing authority.  Such positions are deemed to be “unrecognized tax benefits” which require additional disclosure and recognition of a liability within the financial statements.  The Company had no unrecognized tax benefits as of June 30, 2014 and as of December 31, 2013.

	In May 2014, the Company’s stockholders approved amendments to the Company’s 2009 Equity Incentive Plan, adopting the Amended and Restated 2009 Equity Incentive Plan (the “Equity Plan”), pursuant to which awards of the Company’s common stock may be made to officers, directors, employees, consultants and agents of the Company and its subsidiaries.  The Company recognizes stock-based compensation costs using a graded vesting attribution method whereby costs are recognized over the requisite service period for each separately vesting portion of the award.
	The following table summarizes the status of the Company’s restricted stock grants issued under the Equity Plan at June 30, 2014 and changes during the six months then ended:
	Restricted Stock Grants	Number of		Weighted Average

	For the six months ended June 30, 2014 the Company recognized approximately $0.3 million of compensation expense related to outstanding restricted stock grants.  The Company expects to recognize additional compensation expense related to these awards of approximately $0.4 million over the next 24 months.

	At June 30, 2014, in addition to the Equity Plan options outstanding, the Company has outstanding 126,000 options to purchase shares of the Company’s common stock at an exercise price of $16.00. The options are related to the merger with ECU Silver Mining Inc. (“ECU”) on September 2, 2011 and were issued to former ECU stock option holders to replace options previously issued to them by ECU. The options expire on October 22, 2014.
	Also, pursuant to the Equity Plan, the Company’s board of directors adopted the Non-Employee Director’s Deferred Compensation and Equity Award Plan (the “Deferred Compensation Plan”).  Pursuant to the Deferred Compensation Plan the non-employee directors receive a portion of their compensation in the form of Restricted Stock Units (“RSUs”) issued under the Equity Plan. The RSUs vest on the first anniversary of the grant date and each vested RSU entitles the director to receive one unrestricted share of common stock upon the termination of the director’s board service.
	The following table summarizes the status of the RSU grants issued under the Deferred Compensation Plan at June 30, 2014 and changes during the six months then ended:

	For the six months ended June 30, 2014 the Company recognized approximately $0.3 million of compensation expense related to the RSU grants.  The Company expects to recognize additional compensation expense related to these awards of approximately $0.2 million over the next 12 months.
	Pursuant to the KELTIP (see Note 8) KELTIP Units may be granted to certain officers and key employees of the Company, which units will, once vested, entitle such officers and employees to receive an amount in cash or in Company common stock measured generally by the price of the Company’s common stock on the settlement date. The KELTIP Units are recorded as a liability as discussed in detail in Note 8.

	Prior to the suspension of mining and processing in June 2013 (see Note 1) the Company sold marketable products including concentrates and precipitates at its Velardeña Properties.  During the six months ended June 30, 2014 the Company did not sell any product or incur any related costs as the result of the suspension of mining and processing.
	During the six months ended June 30, 2013 the Company sold marketable products to five customers.  Under the terms of the Company’s agreements with one precipitate customer, title does not pass to the purchaser until the product is received by the refinery, at which point revenue is recognized. For the Company’s other customers, title generally passes when a provisional payment is made, which occurs after the product is shipped and customary sales documents are completed.  Costs related to the sale of metals products include direct and indirect costs incurred to mine, process and market the products.  At June 30, 2013 the Company had written down its metals inventory to net realizable value including a charge to the cost of metals sold of approximately $1.6 million and a charge to depreciation expense of approximately $0.3 million.  Also included in cost of metals sold at June 30, 2013 is a $0.6 million charge related to workforce reduction severance costs.
