The Company operates in Argentina, Mexico, Canada and the United States. It owns a 49% interest in Minera Santa Cruz S.A. (“MSC”), owner of the producing San José silver-gold mine in Santa Cruz, Argentina, which is operated by the joint venture majority owner, Hochschild Mining plc. It also owns and operates the El Gallo 1 mine in Sinaloa, Mexico and the Black Fox Complex in Timmins, Ontario, Canada. Finally, the Company owns the Los Azules copper deposit in San Juan, Argentina, the El Gallo 2 project in Sinaloa, Mexico, the Gold Bar project in Nevada in the United States, and a portfolio of exploration properties in Argentina, Mexico, Nevada, and Timmins, Ontario in Canada.

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”) have 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 (Loss) Income (“Statement of Operations”) for the three months ended March 31, 2018 and 2017, the unaudited Consolidated Balance Sheets as at March 31, 2018 and December 31, 2017, the unaudited Consolidated Statement of Changes in Shareholders’ Equity for the three months ended March 31, 2018 and 2017, and the unaudited Consolidated Statements of Cash Flows for the three months ended March 31, 2018 and 2017, 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 annual report on Form 10-K for the year ended December 31, 2017. 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, 2017. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. Inter-company accounts and transactions have been eliminated.

Recently Adopted Accounting Pronouncements

Statement of Cash Flows – Restricted Cash: In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flow - Restricted Cash (ASU 2016-18). ASU 2016-18 requires that an entity's statement of cash flows explain the change during the period in that entity's total cash and cash equivalents, including amounts generally described as restricted cash or restricted cash equivalents. Therefore, changes in restricted cash and restricted cash equivalents will no longer be shown as specific line items within the statement of cash flows. Additionally, an entity is required to reconcile the cash and cash equivalents on its balance sheet to the cash and cash equivalent balances presented in its statement of cash flows. ASU 2016-18 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017 with early adoption permitted. The Company early adopted the guidance within ASU 2016-18 as of December 31, 2017. The impact of ASU 2016-18 on its financial statements was as follows: (1) changes in restricted cash balances are no longer shown in the statements of cash flows, as these balances are included in the beginning and ending cash balances in the statements of cash flows; and (2) included within Note 16 is a reconciliation between cash balances presented on the balance sheets with the amounts presented in the statements of cash flows. The Company continued to hold material restricted cash during the three months ended March 31, 2018.

Statement of Cash Flows – Classification of Certain Cash Receipts and Cash Payments: In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) – Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 clarifies how entities should classify certain cash receipts and cash payments in the statement of cash flows and amends certain disclosure requirements of ASC 230. The guidance will generally be applied retrospectively and is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those years. The Company has elected to utilize the Cumulative Earnings Approach to classify distributions from equity method investees, this approach is defined in ASU 2016-15 as an acceptable approach. Based on the Cumulative Earnings Approach, if the inception-to-date distributions are greater than the inception to date earnings then, the cash flows from the equity method investee would be recognized as a return of investment within cash inflows from investing activities. Based on the Company’s analysis the inception-to-date distributions are not greater than the inception-to-date earnings for any of the prior year periods nor the three months ended March 31, 2018. Therefore, the adoption of ASU 2016-15 did not result in any change to the classification or presentation of the distributions received from equity method investees in any current or prior period.

Revenue from Contracts with Customers: In 2016, the FASB issued four separate accounting standard updates regarding Topic 606: ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2017-13. These ASUs outline amendments to Topic 606, including reporting revenue gross versus net, identifying performance obligations and licensing and narrow-scope improvements and practical expedients. Adoption of this update by the Company, effective January 1, 2018 was completed using the modified retrospective approach. The modified retrospective method contemplates that comparative periods should not be restated and the cumulative impact of applying the standard should be recognized at the date of initial adoption, January 1, 2018. The Company has elected to apply the method only to new contracts and contracts that were not completed as of January 1, 2018. As expected, the Company did not have any cumulative effect of initially applying the standard for contracts not complete as of January 1, 2018. As a result, the Company has presented comparative periods under legacy GAAP and there has been no change to any line item as a result of adoption of the new standard. There was no material impact to revenue recognition.

Revenue Recognition Accounting Policy: Revenue consists of sales value received for the Company’s principal products, gold and silver. Revenue is recognized when title to gold and silver passes to the buyer and when collectability is reasonably assured. Title passes to the buyer based on terms of the sales contract, usually upon delivery of the product. Product pricing is determined under the sales agreements which are referenced against active and freely traded commodity markets, for example, the London Bullion Market for both gold and silver, in an identical form to the product sold. Gold and silver doré produced from the San José mine is sold at the prevailing spot market price based on the London A.M. fix, while concentrates are sold at the prevailing spot market price based on either the London P.M. fix or average of the London A.M. and London P.M. fix depending on the sales contract. Concentrates are provisionally priced, whereby the selling price is subject to final adjustments at the end of a period ranging from 30 to 90 days after delivery to the customer. The final price is based on the market price of the precious metal content at the relevant quotation point stipulated in the contract. Due to the time elapsed between shipment and the final settlement with the buyer, MSC must estimate the prices at which sales of metals will be settled. At the end of each financial reporting period, previously recorded provisional sales are adjusted to estimated settlement metals prices based on relevant forward market prices until final settlement with the buyer. Any material differences to these differences will be separately disclosed.

The Company entered into a doré sales agreement with a Canadian financial institution in July 2012. Under that agreement, the Company has the option to sell to the institution approximately 90% of the gold and silver contained in doré bars prior to the completion of refining by the third party refiner, which normally takes approximately 10 business days. Revenue is recognized when the Company has provided irrevocable instructions to the refiner to transfer to the purchaser the refined ounces sold upon final processing outturn, and when payment of the purchase price for the purchased doré or bullion has been made in full by the purchaser. There is no judgement involved in revenue recognition as revenue is recognized when payment has been made by the purchaser and the product has been delivered.

The Company also has a contract under which revenue is earned from a toll milling arrangement at the Black Fox Complex. Revenue is recognized when title to the product passes to the customer. This revenue is separately disclosed as Other revenue in the financial statements. There is no judgement involved in revenue recognition from the toll milling agreement as revenue is recognized when the customer takes delivery of the product.

Revenue by operating segments is separately disclosed within Note 12 to the financial statements.

Compensation – Stock Compensation – Scope of Modification Accounting: In May 2017, the FASB issued ASU No. 2017-09 which provides clarity and reduces diversity in practice with respect to the modification of terms or conditions of a share-based payment award. The update to the standard is effective for the Company for fiscal years beginning after December 15, 2017, with early application permitted. The Company has adopted the update as of January 1, 2018 and adoption did not have any impact on the consolidated financial statements or disclosures.

Business Combinations: Definition of a business: In January 2017, the FASB issued ASU No. 2017-01 which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. The update to the standard is effective for the Company beginning after December 15, 2017, with early application permitted. The Company has adopted the update as of January 1, 2018 and the adoption did not have any impact on the consolidated financial statements or disclosures.

Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory: In October 2016, the FASB issued ASU No. 2016-16 to modify the current exception to income tax accounting that required companies to defer the income tax effect of certain intercompany transactions. ASU No. 2016-16 only allows companies to defer the income tax effect of intercompany inventory transactions under an exception to the guidance on income taxes that currently applies to intercompany sales and transfers of all assets. The update to the standard was adopted by the Company beginning January 1, 2018 and adoption of the update did not have any impact on the consolidated financial statements or disclosures.

Financial Instruments - Recognition and Measurement of Financial Assets and Financial Liabilities: In January 2016, the FASB issued ASU No. 2016-01, which updates certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The update to the standard was adopted by the Company beginning January 1, 2018. The new guidance requires entities to measure equity investments (except those accounted for under the equity method, those that result in consolidation of the investee and certain other investments) at fair value and recognize any changes in fair value in net income. Transitional guidance provided that entities with unrealized gains or losses on available for sale (“AFS”) equity securities were required to reclassify those amounts to beginning retained earnings in the year of adoption. As a result, the Company has reclassified the beginning amount of accumulated other comprehensive income related to AFS securities to accumulated deficit and all changes in fair-values of these securities is now reflected in the Statement of Operations in the Company’s net loss for the period.

Recently Issued Accounting Pronouncements

Leases – Amendments: In February 2016, the FASB issued ASU 2016-02 “leases (ASC 842)” which provides that a lessee should recognize the assets and the liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the statement of financial position a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. For leases with a term of twelve months or less, the lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from the previous GAAP. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within such fiscal year, with early adoption permitted. The ASU requires a modified retrospective transition method with the option to elect a package of practical expedients. There are three practical expedients for which an election must be made to apply and the election must be applied to all leases, as follows:

Package of practical expedients – to permit an entity to a) not reassess whether expired or existing contracts contain leases, b) not reassess lease classification for existing or expired leases and c) not consider whether previously capitalized initial direct costs would be appropriate under the new standard.

Hindsight practical expedient – to permit an entity to use hindsight in determining the lease term.

Easements practical expedient – to permit an entity to continue applying its current policy for accounting for land easements that existed as of, or expired before, the effective date of ASC 842 (ASU 2018-01).

The Company expects to elect to apply all of the practical expedients available. During the first quarter the Company has begun preliminary analysis of the effect of the standard on its financial statements as well as review of major contracts. Based on the Company’s preliminary analysis, it is not expected that the adoption of ASC 842 will result in significant changes to the financial statements. However, the analysis remains ongoing. A quantitative estimate of the effect is not reasonably estimable as of the date of this report.
