NOTE 1 NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | |
Nature of Operations and Basis of Presentation | |
McEwen Mining Inc. (the “Company” or “McEwen Mining”) was organized under the laws of the State of Colorado on July 24, 1979. Since inception, the Company has been engaged in the exploration for, development of, production and sale of gold and silver. On January 24, 2012, the Company changed its name from US Gold Corporation to McEwen Mining Inc. after the completion of the acquisition of Minera Andes Inc. (“Minera Andes”) by way of a statutory plan of arrangement under the laws of the Province of Alberta, Canada. | |
The Company operates in Argentina, Mexico, and the United States. It owns a 49% interest in Minera Santa Cruz S.A. (“MSC”), owner and operator of the producing San José mine in Santa Cruz, Argentina, which is controlled by the majority owner of the joint venture, Hochschild Mining plc (‘‘Hochschild’’). It also owns the El Gallo 1 mine in Sinaloa, Mexico, where production resumed in September 2012. In addition to its operating properties, the Company also holds interests in numerous exploration stage properties and projects in Argentina, Mexico and the United States. | |
The interim consolidated financial statements included herein have been prepared by the Company, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) has been condensed or omitted pursuant to such rules and regulations, although the Company believes that the disclosures included are adequate to make the information presented not misleading. | |
In management’s opinion, the unaudited Consolidated Statements of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2014 and 2013, the Consolidated Balance Sheets as at June 30, 2014 (unaudited) and December 31, 2013, the unaudited Consolidated Statement of Changes in Shareholders’ Equity for the six months ended June 30, 2014 and 2013, and the unaudited Consolidated Statements of Cash Flows for the six months ended June 30, 2014 and 2013, contained herein, reflect all adjustments, consisting solely of normal recurring items, which are necessary for the fair presentation of the Company’s financial position, results of operations and cash flows on a basis consistent with that of the Company’s prior audited consolidated financial statements. However, the results of operations for the interim periods may not be indicative of results to be expected for the full fiscal year. Therefore these financial statements should be read in conjunction with the audited financial statements and notes thereto and summary of significant accounting policies included in the Company’s Form 10-K for the year ended December 31, 2013. Except as noted below, there have been no material changes in the footnotes from those accompanying the audited consolidated financial statements contained in the Company’s Form 10-K for the year ended December 31, 2013. | |
The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company accounts and transactions have been eliminated. | |
Recently Adopted Accounting Pronouncements | |
Presentation of an Unrecognized Tax Benefit: In July 2013, ASC guidance was issued related to the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. The updated guidance requires an entity to net its unrecognized tax benefits against the deferred tax assets for the same jurisdiction’s net operating loss carryforward, a similar tax loss, or tax credit carryforwards. A gross presentation will be required only if such carryforwards are not available or would not be used by the entity to settle any additional income taxes resulting from disallowance of the uncertain tax position. The update was effective prospectively for the Company’s fiscal year beginning January 1, 2014. The new guidance affects disclosures only and the adoption had no impact on the Company’s consolidated financial position, results of operations or cash flows. | |
Foreign Currency Matters: In March 2013, ASC guidance was issued related to Foreign Currency Matters to clarify the treatment of cumulative translation adjustments when a parent sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a business within a foreign entity. The updated guidance also resolves the diversity in practice for the treatment of business combinations achieved in stages in a foreign entity. The update was effective prospectively for the Company’s fiscal year beginning January 1, 2014. The updated guidance had no impact on the Company’s consolidated financial position, results of operations or cash flows. | |
Recently Issued Accounting Pronouncements | |
Presentation of Financial Statements (ASC 205) and Property, Plant and Equipment (ASC 360) — Reporting Discontinued Operations and Disclosures of Components of an Entity: In April 2014, ASC guidance was amended to change the requirements for reporting discontinued operations in ASC 205-20. A disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations only if the disposal represents a strategic shift that has, or will have, a major effect on an entity’s operations and financial results when any of the following occurs: (1) the component of an entity or group of components of an entity meets the criteria in ASC 205-20-45-1E to be classified as held for sale; (2) the component of an entity or group of components of an entity is disposed of by sale; (3) the component of an entity or group of components of an entity is disposed of other than by sale. The update is effective prospectively for the Company’s fiscal year beginning January 1, 2015. The new guidance is not expected to have an impact on the Company’s consolidated financial position, results of operations or cash flows. | |
Revenue from Contracts with Customers (ASC 606): In May 2014, ASC 606 was issued related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The standard will be effective for the Company’s fiscal year beginning January 1, 2017, including interim reporting periods within that year. The Company is evaluating the effect that the updated standard will have on its consolidated financial position, results of operations or cash flows. | |

Mineral Property Interests | ||||||||||||||||
During the second quarter of 2014, the Company recorded an impairment charge of $120.4 million relating to its Los Azules copper exploration project (“Los Azules Project”). The Company conducts a review of potential triggering events for all its mineral projects on a quarterly basis. When events or changes in circumstances indicate that the related carrying amounts may not be recoverable, the Company carries out a review and evaluation of its long-lived assets for impairment, in accordance with its accounting policy. Such a triggering event was identified in the second quarter of 2014 with respect to the Company’s Los Azules Project. The triggering event identified was a recently announced acquisition of a copper project located in Argentina, which shares similarities with the Los Azules Project due to its scale, location, and stage of development. Based on the announcement day value of the similar project, the estimated market value per pound of copper equivalent mineralized material from this transaction was below the carrying value per pound of copper equivalent mineralized material of the Los Azules Project, indicating a potential significant decrease in the market price of its Los Azules Project, in accordance with ASC 360-35-21-a, and therefore a requirement to test the Los Azules Project for recoverability. To assist in performing a recoverability test, the Company engaged a third-party valuation firm who used the observed market value per pound of copper equivalent mineralized material based on this recent and other comparable transactions to estimate the fair value of the Los Azules Project. The carrying value of the property exceeded its estimated fair value, resulting in an impairment charge of $120.4 million, along with a resulting deferred income tax recovery of $22.5 million, being recorded in the Statement of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2014. | ||||||||||||||||
Impairments recorded in the second quarter of 2013 related to the Company’s exploration properties in Santa Cruz, Argentina. The impairments were primarily due to an unexpected significant decline in gold and silver market prices, continued inflationary pressures and a new tax on mining reserves in the Province, resulting in a depressed market for exploration properties in Argentina. An impairment charge of $27.7 million, along with a resulting reduction in deferred tax liability and recovery of deferred income taxes of $2.3 million, were included in the Statement of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2013. | ||||||||||||||||
Based on the above, impairment charges were recorded on the following mineral property interests for the three and six months ended June 30, 2014 and 2013. | ||||||||||||||||

Asset Retirement Obligations | ||||||||||||||||
The Company is responsible for reclamation of certain past and future disturbances at its properties. The two most significant properties subject to these obligations are the historic Tonkin property in Nevada and the El Gallo 1 mine in Mexico. | ||||||||||||||||
The current undiscounted estimate of the reclamation costs for existing disturbances on the Tonkin property to the degree required by the U.S. Bureau of Land Management (“BLM”) and the Nevada Department of Environmental Protection (“NDEP”) was $2.7 million as of June 30, 2014. Expenses are expected to be incurred between the years 2014 and 2040. The Company submitted a mine closure plan to the NDEP and BLM for the Tonkin property during the fourth quarter of 2010. As at June 30, 2014, the closure plan has already been approved by the NDEP but is still under review by the BLM pursuant to the National Environmental Policy Act. It is possible that reclamation plan cost estimates and bonding requirements may increase as a result of this review. The Company, however, is unable to meaningfully estimate possible increases at this time. | ||||||||||||||||
Asset Retirement Obligations (Continued) | ||||||||||||||||
For mineral properties in the United States, the Company maintains required reclamation bonding with various governmental agencies. At December 31, 2013, the Company had cash bonding in place of $5.2 million. During the second quarter of 2014, cash bonding requirements were reduced by $0.4 million, to $4.8 million at June 30, 2014. Subsequent to June 30, 2014, the Company replaced its cash bonding with surety bonds of the same amounts. The annual fees are 1.5% of the value of the surety bonds, with an upfront 10% deposit. | ||||||||||||||||
The current undiscounted estimate of the reclamation costs for existing disturbances at the El Gallo 1 mine was $4.6 million as of June 30, 2014. Expenses are expected to be incurred between the years 2014 and 2018. Under Mexican regulations, surety bonding of projected reclamation costs is not required. | ||||||||||||||||
A reconciliation of the Company’s asset retirement obligations for the six months ended June 30, 2014 and for the year ended December 31, 2013 are as follows: | ||||||||||||||||

Amortization of Mineral Property Interests and Asset Retirement Costs | ||||||||||||||||
The definition of proven and probable reserves is set forth in the SEC Industry Guide 7. If proven and probable reserves exist at the Company’s properties, the relevant capitalized mineral property interests and asset retirement costs are to be charged to expense based on the units of production method and upon commencement of production. Since the Company has not completed feasibility or other studies sufficient to characterize the mineralized material at El Gallo 1 as proven or probable reserves, the amortization of the capitalized mineral property interests and asset retirement costs are charged to expense based on the straight-line method over the estimated useful life of the mine. For the three and six months ended June 30, 2014, the Company recorded $0.3 million and $0.6 million, respectively, of amortization expense related to El Gallo 1, which is included in Production Costs Applicable to Sales in the Statement of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2014, of which $0.1 million and $0.1 million, respectively, related to the amortization of capitalized asset retirement costs. | ||||||||||||||||

NOTE 4 INVESTMENT IN MINERA SANTA CRUZ S.A. (“MSC”) — SAN JOSÉ MINE | ||||||||||||||
The Company’s 49% attributable share of earnings from its investment in MSC was a loss of $2.4 million for the three months ended June 30, 2014, and income of $4.6 million for the six months ended June 30, 2014. This compares to losses of $1.6 million and $1.8 million for the three and six months ended June 30, 2013. These amounts are net of the amortization of the fair value increments arising from the purchase price allocation and related income tax expense. Included in the income tax expense is the impact of fluctuations in the exchange rate between the Argentine peso and the U.S. dollar on the peso-denominated deferred tax liability associated with the investment in MSC recorded as part of the acquisition of Minera Andes. As a devaluation of the Argentine peso relative to the U.S. dollar results in a recovery of deferred income taxes, the impact has been an increase to the Company’s income from its investment in MSC for the three and six months ended June 30, 2014. | ||||||||||||||
During the first quarter of 2013, it was determined that the cost of sales reported by MSC under U.S. GAAP for the year and three months ended December 31, 2012 was understated, resulting in an overstatement of MSC’s after-tax net income of $3.9 million. As the error was not material to previously-reported consolidated financial statements, the correction was recorded in the three months ended March 31, 2013. As a result, the income from the Company’s equity investment of 49% in MSC includes an adjustment of $1.9 million, resulting in a reduction of the Company’s Income from Investment in MSC for the six months ended June 30, 2013. | ||||||||||||||
During the second quarter of 2013, the Company recorded an impairment charge of $95.9 million on its investment in MSC, primarily as a result of an unexpected and significant decline in gold and silver market prices, continued inflationary pressures during the year, and amendments to the Santa Cruz Provincial Tax Code and Provincial Tax Law, which imposed a new tax on mining reserves in the Province of Santa Cruz. As the loss in value of the investment was considered other than temporary, an impairment of $95.9 million was recorded in the Company’s Consolidated Statement of Operations and Comprehensive Income (Loss) for the three and six months ended June 30, 2013. | ||||||||||||||
During the fourth quarter of 2013, the Company entered into a vend-in agreement with MSC and subsidiaries of Hochschild pursuant to which both parties agreed to contribute to MSC the mining rights of certain Santa Cruz exploration properties. The carrying value of the Company’s properties of $35.9 million, net of the related deferred tax liability of $17.3 million, was transferred to the Company’s investment in MSC, with no gain or loss recognized upon transfer. | ||||||||||||||
During the three and six months ended June 30, 2014, the Company received $3.2 million and $7.1 million in dividends from MSC, respectively, compared to $nil during the same period in 2013. The Company received an additional dividend payment of 8.1 million Argentine pesos in July 2014, equivalent to approximately $1.0 million based on foreign exchange rates at the date of the dividend receipt, and expects another payment of 8.1 million pesos in the third quarter of 2014, equivalent to approximately $1.0 million based on foreign exchange rates as at June 30, 2014. | ||||||||||||||

NOTE 8 INCOME TAXES | |
The Company’s income tax expense differs from the amount computed by applying the U.S. federal and state statutory corporate income tax rate of 35% primarily as a result of the tax benefit of losses not being recognized and due to changes in the deferred tax liability associated with mineral property interests acquired with the Minera Andes acquisition. This deferred tax liability is impacted by fluctuations in the foreign exchange rate between the Argentine peso and U.S. dollar. For the three and six months ended June 30, 2014, the Company recorded an income tax recovery of $2.5 million and $21.4 million, respectively, as a result of the Argentine peso devaluation, compared to $7.5 million and $13.7 million for the three and six months ended June 30, 2013, respectively. Further, the income tax recovery for the three and six months ended June 30, 2014 includes $22.5 million associated with the impairment of the Los Azules Project, discussed in Note 3, Mineral Property Interests and Asset Retirement Obligations. This compares to an income tax recovery of $4.8 million related to mineral property interests sold or impaired in the three and six months ended June 30, 2013. | |

FAIR VALUE ACCOUNTING | ' | ||||||||||||||||||
NOTE 12 FAIR VALUE ACCOUNTING | |||||||||||||||||||
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 and 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 1Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; | |||||||||||||||||||
Level 2Quoted 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 3Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity). | |||||||||||||||||||
Assets and liabilities measured at fair value on a recurring basis | |||||||||||||||||||
The following table identifies the fair value of the Company’s financial assets and liabilities as reported in the Consolidated Balance Sheets at June 30, 2014 and December 31, 2013 by level within the fair value hierarchy. 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 Company’s cash and cash equivalents are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The cash equivalent instruments that are valued based on quoted market prices in active markets are primarily money market securities. | |||||||||||||||||||
As at June 30, 2014, accounts payable included an accrual of $1.1 million for the fair value of approximately 379,400 shares of common stock that are required to be issued as part of the settlement of certain amounts due by the Company to one of its vendors, as discussed in Note 6, Shareholders’ Equity. As the Company’s stock is quoted on an active market, this liability is classified within Level 1 of the fair value hierarchy. | |||||||||||||||||||
The fair value of other financial assets and liabilities approximate their carrying values due to their short-term nature and historically negligible credit losses. | |||||||||||||||||||
Assets and liabilities measured at fair value on a non-recurring basis | |||||||||||||||||||
