On July 5, 2016, a wholly-owned subsidiary, Blackjack Gold Corporation, a Nevada corporation, was formed for potential purchases of exploration targets. On June 17, 2015, the Board of Directors of the Company approved a reverse stock split of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), at a ratio of 1-for-18 (the “Reverse Stock Split”) which became effective on June 18, 2015. In connection with the Reverse Stock Split, the Company filed a Certificate of Amendment to its Amended and Restated Articles of Incorporation, as amended, with the Nevada Secretary of State to reduce the number of shares of Common Stock the Company is authorized to issue from 800,000,000 to 200,000,000. All share and per share values of the Company’s Common Stock for all periods presented in the accompanying consolidated financial statements are retroactively restated for the effect of the Reverse Stock Split in accordance with Staff Accounting Bulletin Topic 4C: Equity Accounts – Change in Capital Structure (“SAB Topic 4C”).

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	6 Months Ended	12 Months Ended
	Jun. 30, 2018	Dec. 31, 2017
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation and principles of consolidation The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”) and present the consolidated financial statements of the Company and its wholly-owned subsidiaries as of June 30, 2018. All intercompany transactions and balances have been eliminated. All adjustments (consisting of normal recurring items) necessary to present fairly the Company’s financial position as of June 30, 2018, and the results of operations and cash flows for the six months ended June 30, 2018 have been included. The results of operations for the six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. The accounting policies and procedures employed in the preparation of these consolidated financial statements have been derived from the audited financial statements of the Company for the fiscal year ended December 31, 2017, which are contained in the Company’s Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 28, 2018. The consolidated balance sheet as of December 31, 2017, contained herein, was derived from those financial statements. Use of estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet, and revenues and expenses for the period then ended. Actual results may differ significantly from those estimates. Significant estimates made by management include, but are not limited to, the useful life of property and equipment, the valuation of deferred tax assets and liabilities, including valuation allowance, amounts and timing of closure obligations, the assumptions used to calculate fair value of restricted stock units, options and warrants granted, stock-based compensation, beneficial conversion on preferred stock, capitalized mineral rights, asset valuations, timing of the performance criteria of restricted stock units and the fair value of common stock issued. Cash and cash equivalents The Company considers all highly liquid investments with an original maturity of three months or less when acquired to be cash equivalents. The Company places its cash with high credit quality financial institutions. The Company’s accounts at these institutions are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. At June 30, 2018, the Company had bank balances exceeding the FDIC insurance limit on interest bearing accounts. To reduce its risk associated with the failure of such financial institutions, the Company evaluates at least annually the rating of the financial institutions in which it holds deposits. Going concern These unaudited consolidated financial statements of the Company have been prepared assuming that the Company will continue as a going concern, which contemplates, among other things, the realization of assets and the satisfaction of liabilities in the normal course of business over a reasonable period of time. The Company has incurred a net loss of approximately $8.3 million for the six months ended June 30, 2018, has used approximately $7.2 million of net cash in operations for the six months ended June 30, 2018, has incurred a total cumulative deficit of approximately $179.0 million since its inception and requires capital for its contemplated business and exploration activities to take place. The Company plans to raise additional capital to carry out its business plan. The Company’s ability to raise additional capital through future equity and debt securities issuances is unknown. Obtaining additional financing, the successful development of the Company’s contemplated plan of operations, and its transition, ultimately, to profitable operations are necessary for the Company to continue business. The ability to successfully resolve these factors raises substantial doubt about the Company’s ability to continue as a going concern as determined by management. The consolidated financial statements of the Company do not include any adjustments that may result from the outcome of these uncertainties. Restricted cash – non current Restricted cash consists of cash which is held as collateral under surface management surety bonds issued on the Company’s behalf. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows: June 30, 2018 December 31, 2017 (Unaudited) Cash and cash equivalents $ 5,501,245 $ 12,858,873 Restricted cash – non current 3,690,000 3,690,000 Total cash, cash equivalents and restricted cash $ 9,191,245 $ 16,548,873 Fair value of financial instruments The Company adopted Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. The adoption of ASC 820 did not have an impact on the Company’s financial position or operating results, but did expand certain disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below: Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. The Company analyzes all financial instruments with features of both liabilities and equity under the Financial Accounting Standard Board’s (“FASB”) accounting standard for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their estimated fair market values based on the short-term maturity of these instruments. Prepaid expenses and other current assets Prepaid expenses and other current assets of $708,533 and $1,006,779 at June 30, 2018 and December 31, 2017, respectively, consist primarily of costs paid for future services which will occur within a year. Prepaid expenses principally include prepayments for consulting, public relations, and business advisory services, insurance premiums, drilling services, mining claim fees and mineral lease fees which are being amortized over the terms of their respective agreements. Mineral property acquisition and exploration costs Costs of leasing, exploration, carrying and retaining unproven mineral lease properties are expensed as incurred. The Company expenses all mineral exploration costs as incurred as it is still in the exploration stage. the completion of a final feasibility study indicating a mine is economically viable a final decision to commence operating mine development activities to bring a mine into production, the property would enter into the development stage and the Company would capitalize future costs until production is established. When a property reaches the production stage, the related capitalized costs are amortized using the units-of-production method over the estimated life of the proven and probable reserves. If in the future the Company has capitalized mineral properties, these properties will be periodically assessed for impairment. To date, the Company has not established the commercial feasibility of any exploration prospects; therefore, all exploration costs are being expensed. ASC 930-805, “Extractive Activities-Mining: Business Combinations” (“ASC 930-805”), states that mineral rights consist of the legal right to explore, extract, and retain at least a portion of the benefits from mineral deposits. Mining assets include mineral rights. Acquired mineral rights are considered tangible assets under ASC 930-805. ASC 930-805 requires that mineral rights be recognized at fair value as of the acquisition date. As a result, the direct costs to acquire mineral rights are initially capitalized as tangible assets. Mineral rights include costs associated with acquiring patented and unpatented mining claims. ASC 930-805-30-1 and 30-2 provide that, in fair valuing mineral assets, an acquirer should take into account both:  The value beyond proven and probable reserves (“VBPP”) to the extent that a market participant would include VBPP in determining the fair value of the assets.  The effects of anticipated fluctuations in the future market price of minerals in a manner that is consistent with the expectations of market participants. Property and equipment Property and equipment are carried at cost. The cost of repairs and maintenance is expensed as incurred; major replacements and improvements are capitalized. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in income in the year of disposition. Depreciation is calculated on a straight-line basis over the estimated useful life of the assets, generally one to twenty-five years. Impairment of long-lived assets The Company accounts for the impairment or disposal of long-lived assets according to ASC 360, “Property, Plant and Equipment”. The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of long-lived assets, including mineral rights, may not be recoverable. Long-lived assets in the exploration stage are monitored for impairment based on factors such as the Company’s continued right to explore the area, exploration reports, assays, technical reports, drill results and the Company’s continued plans to fund exploration programs on the property, and whether sufficient work has been performed to indicate that the carrying amount of the mineral property cost carried forward as an asset will not be fully recovered. The tests for long-lived assets in the exploration stage are monitored for impairment based on factors such as current market value of the long-lived assets and results of exploration, future asset utilization, business climate, mineral prices and future undiscounted cash flows expected to result from the use of the related assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated future net undiscounted cash flows expected to be generated by the asset. When necessary, impaired assets are written down to estimated fair value based on the best information available. Estimated fair value is generally based on either appraised value or measured by discounting estimated future cash flows. Considerable management judgment is necessary to estimate discounted future cash flows. Accordingly, actual results could vary significantly from such estimates. The Company recognizes an impairment loss when the sum of expected undiscounted future cash flows is less than the carrying amount of the asset. The Company did not record any impairment of its long-lived assets at June 30, 2018 and December 31, 2017, respectively. Asset retirement obligations Asset retirement obligations (“ARO”), consisting primarily of estimated mine reclamation and closure costs at the Company’s Relief Canyon property, are recognized in the period incurred and when a reasonable estimate can be made, and recorded as liabilities at fair value. Such obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to accretion expense. Corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s remaining useful life. Asset retirement obligations are periodically adjusted to reflect changes in the estimated present value resulting from revisions to the estimated timing or amount of reclamation and closure costs. The Company reviews and evaluates its asset retirement obligations annually or more frequently at interim periods if deemed necessary. Income taxes The Company accounts for income taxes pursuant to the provision of ASC 740-10, “Accounting for Income Taxes” (“ASC 740-10”), which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred asset will not be realized. The Company follows the provision of ASC 740-10 related to Accounting for Uncertain Income Tax Positions. When tax returns are filed, there may be uncertainty about the merits of positions taken or the amount of the position that would be ultimately sustained. In accordance with the guidance of ASC 740-10, the benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured at the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefit associated with tax positions taken that exceed the amount measured as described above should be reflected as a liability for uncertain tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company has adopted ASC 740-10-25, “Definition of Settlement”, which provides guidance on how an entity should determine whether a tax position is effectively settled for the purpose of recognizing previously unrecognized tax benefits and provides that a tax position can be effectively settled upon the completion and examination by a taxing authority without being legally extinguished. For tax positions considered effectively settled, an entity would recognize the full amount of tax benefit, even if the tax position is not considered more likely than not to be sustained based solely on the basis of its technical merits and the statute of limitations remains open. The federal and state income tax returns of the Company are subject to examination by the IRS and state taxing authorities, generally for three years after they are filed. Stock-based compensation Stock-based compensation is accounted for based on the requirements of the Share-Based Payment Topic of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires recognition in the consolidated financial statements of the cost of employee and director services received in exchange for an award of equity instruments over the period the employee or director is required to perform the services in exchange for the award (presumptively, the vesting period). ASC 718 also requires measurement of the cost of employee and director services received in exchange for an award based on the grant-date fair value of the award. The Company adopted ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” (“ASU 2016-09”), which makes several modifications to Topic 718. Upon adoption of ASU 2016-09, the Company recognizes the effect of forfeitures in compensation cost as they occur, rather than estimating forfeitures as of the award date. Any previously recognized compensation cost will be reversed in the period of forfeiture. Pursuant to ASC Topic 505-50, “Equity Based Payments to Non-employees”, for share-based payments to consultants and other third-parties, compensation expense is determined at the measurement date. The expense is recognized over the vesting period of the award. Until the measurement date is reached, the total amount of compensation expense remains uncertain. The Company initially records compensation expense based on the fair value of the award at the reporting date. Related party transactions Parties are considered to be related to the Company if the parties, directly or indirectly, through one or more intermediaries, control, are controlled by, or are under common control with the Company. Related parties also include principal owners of the Company, its management, members of the immediate families of principal owners of the Company and its management and other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. The Company discloses all related party transactions. Foreign currency transactions The Company accounts for foreign currency transactions in accordance with ASC 830, “Foreign Currency Matters” (“ASC 830”), specifically the guidance in subsection ASC 830-20, “Foreign Currency Transactions”. The U.S. dollar is the functional and reporting currency for the Company and its subsidiaries. Pursuant to ASC 830, monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting gains or losses upon settlement reported in foreign exchange gain (loss) in the computation of net income (loss). Recent accounting pronouncements In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18. ASU 2016-18 is intended to clarify how entities present restricted cash in the statement of cash flows. The guidance requires entities to show the changes in the total of cash and cash equivalents and restricted cash in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. When cash and cash equivalents and restricted cash are presented in more than one line-item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively. Early adoption was permitted, including adoption in an interim period. The Company early adopted ASU 2016-18 for the three-month period ended December 31, 2017 and its adoption did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”, which eliminates Step 2 from the goodwill impairment test. When an indication of impairment was identified after performing the first step of the goodwill impairment test, Step 2 required that an entity determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) using the same procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the amendments in ASU No. 2017-04, an entity would perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value. An entity would recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value. In addition, an entity must consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. A public business entity that is a SEC filer should adopt the amendments in ASU No. 2017-04 for its annual, or any interim, good will impairment tests in fiscal years beginning after December 15, 2019. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation”. The update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in ASC Topic 718. An entity shall account for the effects of a modification described in ASC paragraphs 718-20-35-3 through 35-9, unless all the following are met: (1) The fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The provisions of this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. The Company’s adoption of this guidance on January 1, 2018 did not have a material impact on the Company’s consolidated results of operations, financial position and related disclosures. In July 2017, the FASB issued ASU 2017-11 “Earnings Per Share (Topic 260)”. The amendments in the update change the classification of certain equity-linked financial instruments (or embedded features) with down round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. For freestanding equity-classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260, Earnings Per Share, to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features would be subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). For public business entities, the amendments in Part I of this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12 “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities”. ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. The guidance is effective for the Company beginning after December 15, 2018, although early adoption is permitted. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07 “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation - Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-Employees. The guidance is effective for public companies for fiscal years, and interim fiscal periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers. The Company is assessing ASU 2018-07 and does not expect it to have a material impact on its accounting and disclosures. Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation and principles of consolidation The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“US GAAP”) and present the consolidated financial statements of the Company and its majority-owned subsidiaries as of December 31, 2017. In the preparation of the consolidated financial statements of the Company, intercompany transactions and balances have been eliminated. Use of estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet, and revenues and expenses for the period then ended. Actual results may differ significantly from those estimates. Significant estimates made by management include, but are not limited to, the useful life of property and equipment, the valuation of deferred tax assets and liabilities, including valuation allowance, amounts and timing of closure obligations, the assumptions used to calculate fair value of restricted stock units, options and warrants granted, stock-based compensation, beneficial conversion on preferred stock, capitalized mineral rights, asset valuations, timing of the performance criteria of restricted stock units and the fair value of common stock issued. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassified amounts have no impact on the Company’s previously reported financial position or results of operations. Cash and cash equivalents The Company considers all highly liquid investments with an original maturity of three months or less when acquired to be cash equivalents. The Company places its cash with high credit quality financial institutions. The Company’s accounts at these institutions are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. At December 31, 2017, the Company had bank balances exceeding the FDIC insurance limit on interest bearing accounts. To reduce its risk associated with the failure of such financial institutions, the Company evaluates at least annually the rating of the financial institutions in which it holds deposits. Restricted cash – non current Restricted cash consists of cash which is held as collateral under surface management surety bonds issued on the Company’s behalf to cover its reclamation obligations. Once the reclamation is completed the surface management surety bonds will be released and the collateral will no longer be required. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows: December 31, December 31, Cash and cash equivalents $ 12,858,873 $ 11,722,102 Restricted cash - non current 3,690,000 2,250,000 Total cash, cash equivalents and restricted cash $ 16,548,873 $ 13,972,102 Fair value of financial instruments The Company adopted Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. The adoption of ASC 820 did not have an impact on the Company’s financial position or operating results, but did expand certain disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below: Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. The Company analyzes all financial instruments with features of both liabilities and equity under the Financial Accounting Standard Board’s (“FASB”) accounting standard for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their estimated fair market values based on the short-term maturity of these instruments. Prepaid expenses and other current assets Prepaid expenses and other current assets of $1,006,779 and $1,139,760 at December 31, 2017 and 2016, respectively, consist primarily of costs paid for future services, which will occur within a year. Prepaid expenses principally include prepayments for consulting, public relations, and business advisory services, insurance premiums, drilling services, mining claim fees and mineral lease fees which are being amortized over the terms of their respective agreements. Included in other current assets are deferred financing costs of $0 and $312,415 at December 31, 2017 and 2016, respectively. The Company deferred these costs until such time that the associated financing was completed. Upon completion and recognition of the proceeds, any deferred financing costs will be reported as a direct deduction from the amount of the proceeds received. As of December31, 2017, the Company determined that the contemplated financing will not be completed therefore the Company expensed such payments of $374,240 during the year ended December 31, 2017. Mineral property acquisition and exploration costs Costs of leasing, exploration, carrying and retaining unproven mineral lease properties are expensed as incurred. The Company expenses all mineral exploration costs as incurred as it is still in the exploration stage. Upon the completion of a final feasibility study indicating a mine is economically viable and a final decision to commence operating mine development activities to bring a mine into production, it would enter into the development stage and capitalize future costs until production is established. When a property reaches the production stage, the related capitalized costs are amortized using the units-of-production method over the estimated life of the proven and probable reserves. If in the future the Company has capitalized mineral properties, these properties will be periodically assessed for impairment. To date, the Company has not established the commercial feasibility of any exploration prospects; therefore, all exploration costs are being expensed. ASC 930-805, “Extractive Activities-Mining: Business Combinations” (“ASC 930-805”), states that mineral rights consist of the legal right to explore, extract, and retain at least a portion of the benefits from mineral deposits. Mining assets include mineral rights. Acquired mineral rights are considered tangible assets under ASC 930-805. ASC 930-805 requires that mineral rights be recognized at fair value as of the acquisition date. As a result, the direct costs to acquire mineral rights are initially capitalized as tangible assets. Mineral rights include costs associated with acquiring patented and unpatented mining claims. ASC 930-805-30-1 and 30-2 provide that, in fair valuing mineral assets, an acquirer should take into account both: The value beyond proven and probable reserves (“VBPP”) to the extent that a market participant would include VBPP in determining the fair value of the assets. The effects of anticipated fluctuations in the future market price of minerals in a manner that is consistent with the expectations of market participants. Property and equipment Property and equipment are carried at cost. The cost of repairs and maintenance is expensed as incurred; major replacements and improvements are capitalized. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in income in the year of disposition. Depreciation is calculated on a straight-line basis over the estimated useful life of the assets, generally one to twenty-five years. Impairment of long-lived assets The Company accounts for the impairment or disposal of long-lived assets according to ASC 360, “Property, Plant and Equipment”. The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of long-lived assets, including mineral rights, may not be recoverable. Long-lived assets in the exploration stage are monitored for impairment based on factors such as the Company’s continued right to explore the area, exploration reports, assays, technical reports, drill results and the Company’s continued plans to fund exploration programs on the property, and whether sufficient work has been performed to indicate that the carrying amount of the mineral property cost carried forward as an asset will not be fully recovered. The tests for long-lived assets in the exploration stage are monitored for impairment based on factors such as current market value of the long-lived assets and results of exploration, future asset utilization, business climate, mineral prices and future undiscounted cash flows expected to result from the use of the related assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated future net undiscounted cash flows expected to be generated by the asset. When necessary, impaired assets are written down to estimated fair value based on the best information available. Estimated fair value is generally based on either appraised value or measured by discounting estimated future cash flows. Considerable management judgment is necessary to estimate discounted future cash flows. Accordingly, actual results could vary significantly from such estimates. The Company recognizes an impairment loss when the sum of expected undiscounted future cash flows is less than the carrying amount of the asset. The Company did not record any impairment of its long-lived assets at December 31, 2017 and 2016, respectively. Asset Retirement Obligations Asset retirement obligations (“ARO”), consisting primarily of estimated mine reclamation and closure costs at the Company’s Relief Canyon property, are recognized in the period incurred and when a reasonable estimate can be made, and recorded as liabilities at fair value. Such obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to accretion expense. Corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s remaining useful life. Asset retirement obligations are periodically adjusted to reflect changes in the estimated present value resulting from revisions to the estimated timing or amount of reclamation and closure costs. The Company reviews and evaluates its asset retirement obligations annually or more frequently at interim periods if deemed necessary. Income taxes The Company accounts for income taxes pursuant to the provision of ASC 740-10, “Accounting for Income Taxes” (“ASC 740-10”), which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred asset will not be realized. The Company follows the provision of ASC 740-10 related to Accounting for Uncertain Income Tax Positions. When tax returns are filed, there may be uncertainty about the merits of positions taken or the amount of the position that would be ultimately sustained. In accordance with the guidance of ASC 740-10, the benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured at the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefit associated with tax positions taken that exceed the amount measured as described above should be reflected as a liability for uncertain tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company has adopted ASC 740-10-25, “Definition of Settlement”, which provides guidance on how an entity should determine whether a tax position is effectively settled for the purpose of recognizing previously unrecognized tax benefits and provides that a tax position can be effectively settled upon the completion and examination by a taxing authority without being legally extinguished. For tax positions considered effectively settled, an entity would recognize the full amount of tax benefit, even if the tax position is not considered more likely than not to be sustained based solely on the basis of its technical merits and the statute of limitations remains open. The federal and state income tax returns of the Company are subject to examination by the IRS and state taxing authorities, generally for three years after they are filed. Stock-based compensation Stock-based compensation is accounted for based on the requirements of the Share-Based Payment Topic of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires recognition in the consolidated financial statements of the cost of employee and director services received in exchange for an award of equity instruments over the period the employee or director is required to perform the services in exchange for the award (presumptively, the vesting period). ASC 718 also requires measurement of the cost of employee and director services received in exchange for an award based on the grant-date fair value of the award. Effective for the fiscal year-ended December 31, 2017, the Company early adopted ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” (“ASU 2016-09”), which makes several modifications to Topic 718. Upon adoption of ASU 2016-09, the Company recognizes the effect of forfeitures in compensation cost as they occur, rather than estimating forfeitures as of the award date. Any previously recognized compensation cost will be reversed in the period of forfeiture. Pursuant to ASC Topic 505-50, “Equity Based Payments to Non-employees”, for share-based payments to consultants and other third-parties, compensation expense is determined at the measurement date. The expense is recognized over the vesting period of the award. Until the measurement date is reached, the total amount of compensation expense remains uncertain. The Company initially records compensation expense based on the fair value of the award at the reporting date. Related party transaction Parties are considered to be related to the Company if the parties, directly or indirectly, through one or more intermediaries, control, are controlled by, or are under common control with the Company. Related parties also include principal owners of the Company, its management, members of the immediate families of principal owners of the Company and its management and other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. The Company discloses all related party transactions. Foreign currency transactions The Company accounts for foreign currency transactions in accordance with ASC 830, “Foreign Currency Matters” (“ASC 830”), specifically the guidance in subsection ASC 830-20, “Foreign Currency Transactions”. The U.S. dollar is the functional and reporting currency for the Company and its subsidiaries. Pursuant to ASC 830, monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting gains or losses upon settlement reported in foreign exchange gain (loss) in the computation of net income (loss). Recent accounting pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those annual periods and is applied retrospectively. Early adoption is permitted. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” (“ASU 2016-09”) as part of FASB's simplification initiative focused on improving areas of GAAP for which cost and complexity may be reduced while maintaining or improving the usefulness of information disclosed within the financial statements. ASU 2016-09 focuses on simplification specifically with regard to share-based payment transactions, including income tax consequences, classification of awards as equity or liabilities and classification on the statement of cash flows. The guidance in ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company’s adoption did not have a material impact on the Company’s consolidated results of operations, financial position and related disclosures. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2016-15”). ASU 2016-15 addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This guidance is effective for the Company beginning with its fiscal year beginning after December 15, 2017, and the interim periods within the fiscal year. The Company adopted the guidance on January 1, 2018 and does not believe it will have a material impact on its consolidated financial statements for fiscal years beginning after December 15, 2017 and the interim periods within those fiscal years. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18. ASU 2016-18 is intended to clarify how entities present restricted cash in the statement of cash flows. The guidance requires entities to show the changes in the total of cash and cash equivalents and restricted cash in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. When cash and cash equivalents and restricted cash are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively. Early adoption is permitted, including adoption in an interim period. The Company early adopted ASU 2016-18 for the three-month period-ended December 31, 2017 and its adoption did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”, which eliminates Step 2 from the goodwill impairment test. When an indication of impairment was identified after performing the first step of the goodwill impairment test, Step 2 required that an entity determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) using the same procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the amendments in ASU No. 2017-04, an entity would perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying value. An entity would recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value. In addition, an entity must consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. A public business entity that is a SEC filer should adopt the amendments in ASU No. 2017-04 for its annual, or any interim, good will impairment tests in fiscal years beginning after December 15, 2019. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In July 2017, the FASB issued ASU 2017-11 “Earnings Per Share (Topic 260)”. The amendments in the update change the classification of certain equity-linked financial instruments (or embedded features) with down round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. For freestanding equity-classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260, Earnings Per Share, to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features would be subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). For public business entities, the amendments in Part I of this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not believe the guidance will have a material impact on its consolidated financial statements. Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.

Mineral Industries Disclosures [Abstract]
MINERAL PROPERTIES	NOTE 3 — MINERAL PROPERTIES The Company’s Relief Canyon property rights currently total approximately 29,000 acres and are comprised of approximately 1,056 owned unpatented mining claims, 120 owned millsite claims, 143 leased unpatented mining claims, and 4,127 acres of leased and 3,739 acres of subleased private lands. Most of the property on which the Relief Canyon deposit is located is subject to a 2% net smelter return production royalty, with a portion of that property subject to net smelter return production royalties totaling 4.5%. The rest of the property is subject, under varying circumstances, to net smelter return production royalties ranging from 2% to 5%. Pershing Pass Property The Pershing Pass property consists of over 765 unpatented mining claims (746 owned and 19 leased) covering approximately 12,900 acres and a mining lease of private lands covering approximately 635 acres. Out of the total unpatented mining claims, 17 unpatented mining claims are subject to a 2% net smelter return royalty and 19 unpatented mining claims are leased with a purchase option. The primary term of the mining lease of private lands is ten years ending in January 2023, which may be extended as long as mineral exploration, development or mining continue on the property. Production from the private lands covered by the lease is subject to a 2% net smelter return royalty on all metals produced other than gold, and to a royalty on gold indexed to the gold price, ranging from 2% at gold prices of less than $500 per ounce to 3.5% at gold prices over $1,500 per ounce. Prior to one year after commercial production begins, the Company can repurchase up to 3% of the royalty on gold production at the rate of $600,000 for each 1%. In September 2013, the Company entered into a lease agreement and purchase option for 19 unpatented mining claims (approximately 400 acres) in the Pershing Pass Property. Production from the lease is subject to a 1% net smelter return royalty on precious metals and a 0.5% net smelter royalty on all other metals produced from the leased property. Prior to production, and starting in September 2016, the Company is required to pay a $10,000 annual advance minimum royalty payment until September 2023. The annual advance minimum royalty payment increases to $12,500 in September 2023, to $15,000 in September 2028 and to $20,000 in September 2033. The Company has the right to buy the leased claims at any time for $250,000. Coal Canyon Property In December 2017, the Company entered into two mining leases at Coal Canyon, which is west of the Relief Canyon Mine. One such mining lease with Good Springs Exploration, LLC and Clancy Wendt (collectively “Lessor”) covers 43 unpatented mining claims adding 800 acres to the Company’s property holdings. The lease contains customary terms and conditions, with a primary term of ten years, which may be extended, annual advance royalty payments to Lessor starting at $20,000 per year, capping at $50,000, which payments are recoupable against a 3% net smelter return production royalty, which royalty can be bought down by one percent point of net smelter return for a payment of , and also includes a conditional purchase option for $350,000. A second mining lease with New Nevada Resources, LLC and New Nevada Lands, LLC (collectively “New Nevada”) covers 1,899 acres of fee land. The lease contains customary terms and conditions, with a primary term of twenty years, which may be extended, with annual advance royalty payments to New Nevada starting at $10 per acre capping at $25 per acre, which payments are recoupable against a 3% net smelter return production royalty. This royalty can be reduced by one percent of net smelter return in exchange for a payment of $1 million, and also includes a conditional purchase option at a price of $500 per acre. Newmont Properties On April 5, 2012, the Company purchased from Victoria Gold Corp. and Victoria Resources (US) Inc. (collectively, “Victoria”) their interest in approximately 13,300 acres of mining claims and private lands adjacent to the Company’s original landholdings at the Relief Canyon Mine in Pershing County, Nevada. Approximately 8,900 acres of the lands that the Company acquired from Victoria were a leasehold interest comprised of unpatented mining claims and private lands subject to a 2006 Mineral Lease and Sublease with Newmont USA Ltd. (“Newmont”), which the Company refers to as the Newmont Leased property. At that time, the Newmont Leased property consisted of 155 unpatented lode mining claims owned by Newmont comprising approximately 2,800 acres, approximately 4,900 acres of privately-owned fee minerals leased by Newmont from the owners, and 62 unpatented mining claims that were owned by Victoria within the Newmont Leased property and area of interest. On January 14, 2015, the Company entered into an Asset Purchase Agreement with Newmont (the “Asset Purchase Agreement”) pursuant to which the Company acquired for $6.0 million, 74 unpatented mining claims totaling approximately 1,300 acres that the Company had previously leased from Newmont, and entered into a new mining lease directly with New Nevada Resources, LLC and New Nevada Lands, LLC for approximately 1,600 acres of fee, or private, land that the Company had previously subleased from Newmont. As part of the January 2015 transactions completed pursuant to the Asset Purchase Agreement, a subsidiary of the Company entered into a Mining Lease (the “2015 Mining Lease”) with New Nevada Resources, LLC and New Nevada Lands, LLC (the “Owners”), covering certain fee lands (the “Leased Properties”) included in the Company’s Relief Canyon properties. The 2015 Mining Lease has a term of twenty years and for as long thereafter as any mining, development or processing operations are being conducted on a continuous basis. The 2015 Mining Lease contains customary terms and conditions, including an advance royalty and a 2.5% net smelter returns production royalty on the Leased Properties payable to the Owners. Newmont Leased Property As part of the Asset Purchase Agreement transactions, Newmont and the Company entered into an amendment of the 2006 Minerals Lease and Sublease (the “Third Amendment”), pursuant to which the Company agreed to a $2.6 million work commitment on the properties remaining subject to the 2006 Minerals Lease and Sublease to be expended by the seventh anniversary of the effective date of the Third Amendment. Upon the eighth anniversary of the effective date of the Third Amendment, the Company shall pay an annual rental payment of $10.00 per acre if the Company does not incur $500,000 in qualified expenditures during the preceding year. Expenditures incurred in excess of the annual work commitment or rental payment obligation may be carried forward as credits against future annual work commitment obligations or rental payment obligations. As of December 15, 2017, the most recent cost reporting date under the Third Amendment, the Company can credit approximately $2.9 million in exploration expenditures already incurred against the remaining $2.3 million work commitment and future rental payment obligations. Also as part of the transactions completed pursuant to the Asset Purchase Agreement, Newmont and the Owners entered into a new Mining Lease (the “2015 Newmont Lease”) covering about 2,770 acres of private lands included in the Company’s Relief Canyon properties (the “Subleased Properties”) and subleased by the Company from Newmont pursuant to the 2006 Minerals Lease and Sublease. The 2015 Newmont Lease has a term of twenty years and for as long thereafter as any mining, development or processing operations are being conducted on a continuous basis. The 2015 Newmont Lease contains customary terms and conditions, including an advance royalty and a 2.5% net smelter returns production royalty on the Subleased Properties payable to the Owners. The Company continues to hold rights to the Subleased Properties pursuant to its 2006 Minerals Lease and Sublease with Newmont. On March 29, 2017, the Company entered into a Mining Sublease with Newmont granting the Company the exclusive right to prospect, explore for, develop, and mine minerals on certain lands within the Pershing Pass area south of the Relief Canyon Mine. The Mining Sublease has an initial term of ten years and may be extended by the Company until December 3, 2034 and so long thereafter as any mining, development, or processing operations are being conducted continuously. The Mining Sublease calls for the Company to make minimum work expenditures for the first four years of the Mining Sublease, followed by annual advanced minimum royalty payments to Newmont to maintain the Mining Sublease in good standing. The Sublease may be terminated any time after providing 90-days written notice of termination. If the required minimum work commitment of $500,000 has not been satisfied prior to termination the Company must pay Newmont the difference between the $500,000 required minimum work commitment and costs already incurred by the Company towards the required minimum work commitment. As of June 30, 2018, the most recent cost reporting date under the Mining Sublease, the Company can credit approximately $270,000 in exploration expenditures already incurred against the $1.5 million work commitment. General In February 2018, the Company increased its statewide surface management surety bonds by $200,000 with the United States Department of the Interior Bureau of Land Management (“BLM”) as required by the State of Nevada. No additional collateral was required. As of June 30, 2018, the Company had posted statewide surface management surety bonds in the total amount of approximately $12.5 million, which was approximately $80,000 in excess of the coverage requirement as of June 30, 2018, to reclaim land disturbed in its exploration and mining operations. The surface management surety bonds are provided through third-party insurance underwriters. The Company was required to deposit a total of $3,690,000, or approximately 30% of the total surety bonds, in collateral accounts. The funds deposited in the collateral accounts are classified as restricted cash – noncurrent on the Company’s balance sheet. As of June 30, 2018, based on management’s review of the carrying value of mineral rights, management determined that there is no evidence that the cost of these acquired mineral rights will not be fully recovered and accordingly, the Company determined that no adjustment to the carrying value of mineral rights was required. As of the date of these consolidated financial statements, the Company has not established any proven or probable reserves on its mineral properties and has incurred only acquisition and exploration costs.

The Company’s ability to draw down on the Facility was subject to the negotiation and execution of definitive agreements, completion by the Lender of its due diligence review and the satisfaction of other customary closing conditions. The Facility, when completed, would have been available for up to three draws occurring during a period of five months following the closing date. As a condition to any such draw, the Company would have been required to raise equity financing not less than the amount drawn. Amounts drawn under the Facility would be secured by a lien on the Relief Canyon Mine and processing facilities and would bear interest at 9.0% per annum. Amounts drawn would mature three years following the date drawn, with monthly principal payments commencing on the earlier of June 30, 2018 or upon achievement of commercial production at the Relief Canyon Mine. The proceeds of the Facility would be use to advance the Relief Canyon project towards production. The Company has paid the Lender a structuring fee of $200,000 and $105,000 for costs associated with their legal and operational due diligence efforts. In addition, the Company has incurred related legal fees and expenses of $69,240. As of December 31, 2017, the Company determined that the financing would not be completed. Accordingly, the Company has reclassified $374,240 from prepaid expenses and other current assets to interest expense and other finance costs for the year-ended December 31, 2017.

INCOME TAXES

INCOME TAXES	12 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 9 — INCOME TAXES The Company accounts for income taxes under ASC Topic 740: Income Taxes which requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statements and the tax basis of assets and liabilities, and for the expected future tax benefit to be derived from tax losses and tax credit carryforwards. ASC Topic 740 additionally requires the establishment of a valuation allowance to reflect the likelihood of realization of deferred tax assets. The Company has a net operating loss carryforward for tax purposes totaling approximately $75.7 million at December 31, 2017, expiring through the year 2037. Internal Revenue Code Section 382 places a limitation on the amount of taxable income that can be offset by carryforwards after certain ownership shifts. The table below summarizes the differences between the Company’s effective tax rate and the statutory federal rate as follows for the year ended December 31, 2017 and 2016: December 31, December 31, Tax benefit computed at “expected” statutory rate $ (4,452,130 ) $ (5,316,096 ) State income taxes, net of benefit — — Permanent differences: Stock based compensation and consulting 199,654 629,133 Other 7,888 155,300 Change in Tax Rates 14,086,726 — Increase (decrease) in valuation allowance (9,842,138 ) 4,531,663 Net income tax benefit $ - $ - The table below summarizes the differences between the Company’s effective tax rate and the statutory federal rate as follows for the year ended December 31, 2017 and 2016: December 31, December 31, Computed “expected” tax expense (benefit) (34.0 )% (34.0 )% State income taxes 0 % 0 % Permanent differences 1.58 % 5.02 % Change in Tax Rates 107.58 % — % Change in valuation allowance (75.16 )% 28.98 % Effective tax rate 0.0 % 0.0 % On December 22, 2017 the United States (“U.S.”) Government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act establishes new tax laws effective January 1, 2018 including but not limited to, (1) reduction of U.S. federal corporate tax rate to 21 percent; (2) the elimination of the corporate alternative minimum tax (AMT) and refunding of existing AMT credit carryforwards ; (3) limitations on deductible interest expense; (4) the repeal of the of the domestic production activity deduction (DPAD); and (5) limitations on net operating losses (NOL’s) generated after December 31, 2017 to 80 percent of taxable income. The NOL’s generated in 2018 and beyond are to be carried forward indefinitely with no carryback. The Company is subject to the provisions of ASC 740-10 which requires that the effect on deferred tax assets and liabilities of a change in tax rates be recognized in the period the tax rate change was enacted. The carrying value of our U.S. deferred taxes is determined by the enacted U.S. corporate income tax rate. Consequently, the reduction in the U.S. corporate income tax rate impacts the carrying value of our deferred tax assets. Under the new corporate income tax rate of 21%, the net deferred tax asset position will decrease as will the related valuation allowance. The Company has not completed its assessment for the income tax effects of the Tax Act but has recorded reasonable estimates of the effects. Further analysis could potentially affect the measurement of deferred tax balances or potentially give rise to new deferred tax amounts. The Company has a deferred tax asset which is summarized as follows at December 31, 2017 and 2016: Deferred tax assets: December 31, December 31, Net operating loss carryover $ 15,896,934 $ 21,486,659 Stock based compensation 2,782,257 4,422,167 Depreciable and depletable assets (16,203 ) (212,727 ) Mining explorations 3,144,263 5,390,018 Capital loss carryforward 915,886 1,482,865 Other 32,346 28,639 Less: valuation allowance (22,755,483 ) (32,597,621 ) Net deferred tax asset $ — $ — After consideration of all the evidence, both positive and negative, management has recorded a full valuation allowance at December 31, 2017, due to the uncertainty of realizing the deferred income tax assets. The valuation allowance was decreased by approximately $9.8 million.

All adjustments (consisting of normal recurring items) necessary to present fairly the Company’s financial position as of June 30, 2018, and the results of operations and cash flows for the six months ended June 30, 2018 have been included. The results of operations for the six months ended June 30, 2018 are not necessarily indicative of the results to be expected for the full year. The accounting policies and procedures employed in the preparation of these consolidated financial statements have been derived from the audited financial statements of the Company for the fiscal year ended December 31, 2017, which are contained in the Company’s Form 10-K as filed with the Securities and Exchange Commission (“SEC”) on March 28, 2018. The consolidated balance sheet as of December 31, 2017, contained herein, was derived from those financial statements.

Use of estimates	Use of estimates In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated balance sheet, and revenues and expenses for the period then ended. Actual results may differ significantly from those estimates. Significant estimates made by management include, but are not limited to, the useful life of property and equipment, the valuation of deferred tax assets and liabilities, including valuation allowance, amounts and timing of closure obligations, the assumptions used to calculate fair value of restricted stock units, options and warrants granted, stock-based compensation, beneficial conversion on preferred stock, capitalized mineral rights, asset valuations, timing of the performance criteria of restricted stock units and the fair value of common stock issued.

Reclassifications		Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. The reclassified amounts have no impact on the Company’s previously reported financial position or results of operations.
Cash and cash equivalents	Cash and cash equivalents The Company considers all highly liquid investments with an original maturity of three months or less when acquired to be cash equivalents. The Company places its cash with high credit quality financial institutions. The Company’s accounts at these institutions are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. At June 30, 2018, the Company had bank balances exceeding the FDIC insurance limit on interest bearing accounts. To reduce its risk associated with the failure of such financial institutions, the Company evaluates at least annually the rating of the financial institutions in which it holds deposits.

Going concern	Going concern These unaudited consolidated financial statements of the Company have been prepared assuming that the Company will continue as a going concern, which contemplates, among other things, the realization of assets and the satisfaction of liabilities in the normal course of business over a reasonable period of time. The Company has incurred a net loss of approximately $8.3 million for the six months ended June 30, 2018, has used approximately $7.2 million of net cash in operations for the six months ended June 30, 2018, has incurred a total cumulative deficit of approximately $179.0 million since its inception and requires capital for its contemplated business and exploration activities to take place. The Company plans to raise additional capital to carry out its business plan. The Company’s ability to raise additional capital through future equity and debt securities issuances is unknown. Obtaining additional financing, the successful development of the Company’s contemplated plan of operations, and its transition, ultimately, to profitable operations are necessary for the Company to continue business. The ability to successfully resolve these factors raises substantial doubt about the Company’s ability to continue as a going concern as determined by management. The consolidated financial statements of the Company do not include any adjustments that may result from the outcome of these uncertainties.
Restricted cash - non current	Restricted cash – non current Restricted cash consists of cash which is held as collateral under surface management surety bonds issued on the Company’s behalf.

Fair value of financial instruments	Fair value of financial instruments The Company adopted Accounting Standards Codification (“ASC”) 820, “Fair Value Measurements and Disclosures” (“ASC 820”), for assets and liabilities measured at fair value on a recurring basis. ASC 820 establishes a common definition for fair value to be applied to existing generally accepted accounting principles that requires the use of fair value measurements, establishes a framework for measuring fair value and expands disclosure about such fair value measurements. The adoption of ASC 820 did not have an impact on the Company’s financial position or operating results, but did expand certain disclosures. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Additionally, ASC 820 requires the use of valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. These inputs are prioritized below: Level 1: Observable inputs such as quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs for which there is little or no market data, which require the use of the reporting entity’s own assumptions. The Company analyzes all financial instruments with features of both liabilities and equity under the Financial Accounting Standard Board’s (“FASB”) accounting standard for such instruments. Under this standard, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The carrying amounts reported in the consolidated balance sheets for cash and cash equivalents, prepaid expenses and other current assets, accounts payable and accrued expenses approximate their estimated fair market values based on the short-term maturity of these instruments.

Prepaid expenses and other current assets	Prepaid expenses and other current assets Prepaid expenses and other current assets of $708,533 and $1,006,779 at June 30, 2018 and December 31, 2017, respectively, consist primarily of costs paid for future services which will occur within a year. Prepaid expenses principally include prepayments for consulting, public relations, and business advisory services, insurance premiums, drilling services, mining claim fees and mineral lease fees which are being amortized over the terms of their respective agreements.	Prepaid expenses and other current assets Prepaid expenses and other current assets of $1,006,779 and $1,139,760 at December 31, 2017 and 2016, respectively, consist primarily of costs paid for future services, which will occur within a year. Prepaid expenses principally include prepayments for consulting, public relations, and business advisory services, insurance premiums, drilling services, mining claim fees and mineral lease fees which are being amortized over the terms of their respective agreements. Included in other current assets are deferred financing costs of $0 and $312,415 at December 31, 2017 and 2016, respectively. The Company deferred these costs until such time that the associated financing was completed. Upon completion and recognition of the proceeds, any deferred financing costs will be reported as a direct deduction from the amount of the proceeds received. As of December31, 2017, the Company determined that the contemplated financing will not be completed therefore the Company expensed such payments of $374,240 during the year ended December 31, 2017.
Mineral property acquisition and exploration costs	Mineral property acquisition and exploration costs Costs of leasing, exploration, carrying and retaining unproven mineral lease properties are expensed as incurred. The Company expenses all mineral exploration costs as incurred as it is still in the exploration stage. the completion of a final feasibility study indicating a mine is economically viable a final decision to commence operating mine development activities to bring a mine into production, the property would enter into the development stage and the Company would capitalize future costs until production is established. When a property reaches the production stage, the related capitalized costs are amortized using the units-of-production method over the estimated life of the proven and probable reserves. If in the future the Company has capitalized mineral properties, these properties will be periodically assessed for impairment. To date, the Company has not established the commercial feasibility of any exploration prospects; therefore, all exploration costs are being expensed. ASC 930-805, “Extractive Activities-Mining: Business Combinations” (“ASC 930-805”), states that mineral rights consist of the legal right to explore, extract, and retain at least a portion of the benefits from mineral deposits. Mining assets include mineral rights. Acquired mineral rights are considered tangible assets under ASC 930-805. ASC 930-805 requires that mineral rights be recognized at fair value as of the acquisition date. As a result, the direct costs to acquire mineral rights are initially capitalized as tangible assets. Mineral rights include costs associated with acquiring patented and unpatented mining claims. ASC 930-805-30-1 and 30-2 provide that, in fair valuing mineral assets, an acquirer should take into account both:  The value beyond proven and probable reserves (“VBPP”) to the extent that a market participant would include VBPP in determining the fair value of the assets.  The effects of anticipated fluctuations in the future market price of minerals in a manner that is consistent with the expectations of market participants.	Mineral property acquisition and exploration costs Costs of leasing, exploration, carrying and retaining unproven mineral lease properties are expensed as incurred. The Company expenses all mineral exploration costs as incurred as it is still in the exploration stage.

When a property reaches the production stage, the related capitalized costs are amortized using the units-of-production method over the estimated life of the proven and probable reserves. If in the future the Company has capitalized mineral properties, these properties will be periodically assessed for impairment. To date, the Company has not established the commercial feasibility of any exploration prospects; therefore, all exploration costs are being expensed. ASC 930-805, “Extractive Activities-Mining: Business Combinations” (“ASC 930-805”), states that mineral rights consist of the legal right to explore, extract, and retain at least a portion of the benefits from mineral deposits. Mining assets include mineral rights. Acquired mineral rights are considered tangible assets under ASC 930-805. ASC 930-805 requires that mineral rights be recognized at fair value as of the acquisition date. As a result, the direct costs to acquire mineral rights are initially capitalized as tangible assets. Mineral rights include costs associated with acquiring patented and unpatented mining claims. ASC 930-805-30-1 and 30-2 provide that, in fair valuing mineral assets, an acquirer should take into account both: The value beyond proven and probable reserves (“VBPP”) to the extent that a market participant would include VBPP in determining the fair value of the assets. The effects of anticipated fluctuations in the future market price of minerals in a manner that is consistent with the expectations of market participants.
Property and equipment	Property and equipment Property and equipment are carried at cost. The cost of repairs and maintenance is expensed as incurred; major replacements and improvements are capitalized. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gains or losses are included in income in the year of disposition. Depreciation is calculated on a straight-line basis over the estimated useful life of the assets, generally one to twenty-five years.

Impairment of long-lived assets	Impairment of long-lived assets The Company accounts for the impairment or disposal of long-lived assets according to ASC 360, “Property, Plant and Equipment”. The Company continually monitors events and changes in circumstances that could indicate that the carrying amounts of long-lived assets, including mineral rights, may not be recoverable. Long-lived assets in the exploration stage are monitored for impairment based on factors such as the Company’s continued right to explore the area, exploration reports, assays, technical reports, drill results and the Company’s continued plans to fund exploration programs on the property, and whether sufficient work has been performed to indicate that the carrying amount of the mineral property cost carried forward as an asset will not be fully recovered. The tests for long-lived assets in the exploration stage are monitored for impairment based on factors such as current market value of the long-lived assets and results of exploration, future asset utilization, business climate, mineral prices and future undiscounted cash flows expected to result from the use of the related assets. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the estimated future net undiscounted cash flows expected to be generated by the asset. When necessary, impaired assets are written down to estimated fair value based on the best information available. Estimated fair value is generally based on either appraised value or measured by discounting estimated future cash flows. Considerable management judgment is necessary to estimate discounted future cash flows. Accordingly, actual results could vary significantly from such estimates. The Company recognizes an impairment loss when the sum of expected undiscounted future cash flows is less than the carrying amount of the asset. The Company did not record any impairment of its long-lived assets at June 30, 2018 and December 31, 2017, respectively.

The Company did not record any impairment of its long-lived assets at December 31, 2017 and 2016, respectively.
Asset retirement obligations	Asset retirement obligations Asset retirement obligations (“ARO”), consisting primarily of estimated mine reclamation and closure costs at the Company’s Relief Canyon property, are recognized in the period incurred and when a reasonable estimate can be made, and recorded as liabilities at fair value. Such obligations, which are initially estimated based on discounted cash flow estimates, are accreted to full value over time through charges to accretion expense. Corresponding asset retirement costs are capitalized as part of the carrying amount of the related long-lived asset and depreciated over the asset’s remaining useful life. Asset retirement obligations are periodically adjusted to reflect changes in the estimated present value resulting from revisions to the estimated timing or amount of reclamation and closure costs. The Company reviews and evaluates its asset retirement obligations annually or more frequently at interim periods if deemed necessary.

Income taxes	Income taxes The Company accounts for income taxes pursuant to the provision of ASC 740-10, “Accounting for Income Taxes” (“ASC 740-10”), which requires, among other things, an asset and liability approach to calculating deferred income taxes. The asset and liability approach requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided to offset any net deferred tax assets for which management believes it is more likely than not that the net deferred asset will not be realized. The Company follows the provision of ASC 740-10 related to Accounting for Uncertain Income Tax Positions. When tax returns are filed, there may be uncertainty about the merits of positions taken or the amount of the position that would be ultimately sustained. In accordance with the guidance of ASC 740-10, the benefit of a tax position is recognized in the financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more likely than not recognition threshold are measured at the largest amount of tax benefit that is more than 50 percent likely of being realized upon settlement with the applicable taxing authority. The portion of the benefit associated with tax positions taken that exceed the amount measured as described above should be reflected as a liability for uncertain tax benefits in the accompanying balance sheet along with any associated interest and penalties that would be payable to the taxing authorities upon examination. The Company has adopted ASC 740-10-25, “Definition of Settlement”, which provides guidance on how an entity should determine whether a tax position is effectively settled for the purpose of recognizing previously unrecognized tax benefits and provides that a tax position can be effectively settled upon the completion and examination by a taxing authority without being legally extinguished. For tax positions considered effectively settled, an entity would recognize the full amount of tax benefit, even if the tax position is not considered more likely than not to be sustained based solely on the basis of its technical merits and the statute of limitations remains open. The federal and state income tax returns of the Company are subject to examination by the IRS and state taxing authorities, generally for three years after they are filed.

Stock-based compensation	Stock-based compensation Stock-based compensation is accounted for based on the requirements of the Share-Based Payment Topic of ASC 718, “Compensation — Stock Compensation” (“ASC 718”), which requires recognition in the consolidated financial statements of the cost of employee and director services received in exchange for an award of equity instruments over the period the employee or director is required to perform the services in exchange for the award (presumptively, the vesting period). ASC 718 also requires measurement of the cost of employee and director services received in exchange for an award based on the grant-date fair value of the award. The Company adopted ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” (“ASU 2016-09”), which makes several modifications to Topic 718. Upon adoption of ASU 2016-09, the Company recognizes the effect of forfeitures in compensation cost as they occur, rather than estimating forfeitures as of the award date. Any previously recognized compensation cost will be reversed in the period of forfeiture. Pursuant to ASC Topic 505-50, “Equity Based Payments to Non-employees”, for share-based payments to consultants and other third-parties, compensation expense is determined at the measurement date. The expense is recognized over the vesting period of the award. Until the measurement date is reached, the total amount of compensation expense remains uncertain. The Company initially records compensation expense based on the fair value of the award at the reporting date.

ASC 718 also requires measurement of the cost of employee and director services received in exchange for an award based on the grant-date fair value of the award. Effective for the fiscal year-ended December 31, 2017, the Company early adopted ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” (“ASU 2016-09”), which makes several modifications to Topic 718. Upon adoption of ASU 2016-09, the Company recognizes the effect of forfeitures in compensation cost as they occur, rather than estimating forfeitures as of the award date.

Related party transactions	Related party transactions Parties are considered to be related to the Company if the parties, directly or indirectly, through one or more intermediaries, control, are controlled by, or are under common control with the Company. Related parties also include principal owners of the Company, its management, members of the immediate families of principal owners of the Company and its management and other parties with which the Company may deal if one party controls or can significantly influence the management or operating policies of the other to an extent that one of the transacting parties might be prevented from fully pursuing its own separate interests. The Company discloses all related party transactions.

Foreign currency transactions	Foreign currency transactions The Company accounts for foreign currency transactions in accordance with ASC 830, “Foreign Currency Matters” (“ASC 830”), specifically the guidance in subsection ASC 830-20, “Foreign Currency Transactions”. The U.S. dollar is the functional and reporting currency for the Company and its subsidiaries. Pursuant to ASC 830, monetary assets and liabilities denominated in foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date, with the resulting gains or losses upon settlement reported in foreign exchange gain (loss) in the computation of net income (loss).

Recent accounting pronouncements	Recent accounting pronouncements In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18. ASU 2016-18 is intended to clarify how entities present restricted cash in the statement of cash flows. The guidance requires entities to show the changes in the total of cash and cash equivalents and restricted cash in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. When cash and cash equivalents and restricted cash are presented in more than one line-item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively. Early adoption was permitted, including adoption in an interim period. The Company early adopted ASU 2016-18 for the three-month period ended December 31, 2017 and its adoption did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”, which eliminates Step 2 from the goodwill impairment test. When an indication of impairment was identified after performing the first step of the goodwill impairment test, Step 2 required that an entity determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) using the same procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Under the amendments in ASU No. 2017-04, an entity would perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value. An entity would recognize an impairment charge for the amount by which the carrying value exceeds the reporting unit’s fair value. In addition, an entity must consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. A public business entity that is a SEC filer should adopt the amendments in ASU No. 2017-04 for its annual, or any interim, good will impairment tests in fiscal years beginning after December 15, 2019. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, “Compensation - Stock Compensation”. The update provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting in ASC Topic 718. An entity shall account for the effects of a modification described in ASC paragraphs 718-20-35-3 through 35-9, unless all the following are met: (1) The fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified; (2) The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (3) The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The provisions of this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2017. The Company’s adoption of this guidance on January 1, 2018 did not have a material impact on the Company’s consolidated results of operations, financial position and related disclosures. In July 2017, the FASB issued ASU 2017-11 “Earnings Per Share (Topic 260)”. The amendments in the update change the classification of certain equity-linked financial instruments (or embedded features) with down round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. For freestanding equity-classified financial instruments, the amendments require entities that present earnings per share (“EPS”) in accordance with Topic 260, Earnings Per Share, to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features would be subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). For public business entities, the amendments in Part I of this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In August 2017, the FASB issued ASU 2017-12 “Derivatives and Hedging (Topic 815) Targeted Improvements to Accounting for Hedging Activities”. ASU 2017-12 eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. The guidance is effective for the Company beginning after December 15, 2018, although early adoption is permitted. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07 “Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting.” These amendments expand the scope of Topic 718, Compensation - Stock Compensation (which currently only includes share-based payments to employees) to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity - Equity-Based Payments to Non-Employees. The guidance is effective for public companies for fiscal years, and interim fiscal periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers. The Company is assessing ASU 2018-07 and does not expect it to have a material impact on its accounting and disclosures. Other accounting standards that have been issued or proposed by FASB that do not require adoption until a future date are not expected to have a material impact on the consolidated financial statements upon adoption. The Company does not discuss recent pronouncements that are not anticipated to have an impact on or are unrelated to its financial condition, results of operations, cash flows or disclosures.	Recent accounting pronouncements In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases. The new guidance will be effective for fiscal years beginning after December 15, 2018, and interim periods within those annual periods and is applied retrospectively. Early adoption is permitted. The Company does not believe the guidance will have a material impact on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation - Stock Compensation (Topic 718)” (“ASU 2016-09”) as part of FASB's simplification initiative focused on improving areas of GAAP for which cost and complexity may be reduced while maintaining or improving the usefulness of information disclosed within the financial statements. ASU 2016-09 focuses on simplification specifically with regard to share-based payment transactions, including income tax consequences, classification of awards as equity or liabilities and classification on the statement of cash flows. The guidance in ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted. The Company’s adoption did not have a material impact on the Company’s consolidated results of operations, financial position and related disclosures. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the FASB Emerging Issues Task Force)” (“ASU 2016-15”). ASU 2016-15 addresses the following eight specific cash flow issues: Debt prepayment or debt extinguishment costs; settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies (including bank-owned life insurance policies); distributions received from equity method investees; beneficial interests in securitization transactions; and separately identifiable cash flows and application of the predominance principle. This guidance is effective for the Company beginning with its fiscal year beginning after December 15, 2017, and the interim periods within the fiscal year. The Company adopted the guidance on January 1, 2018 and does not believe it will have a material impact on its consolidated financial statements for fiscal years beginning after December 15, 2017 and the interim periods within those fiscal years. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash,” or ASU 2016-18.

This reconciliation can be presented either on the face of the statement of cash flows or in the notes to the financial statements. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and is to be applied retrospectively. Early adoption is permitted, including adoption in an interim period. The Company early adopted ASU 2016-18 for the three-month period-ended December 31, 2017 and its adoption did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment”, which eliminates Step 2 from the goodwill impairment test.

In addition, an entity must consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable.
