Nature of Operations [Abstract]
Nature of operations	1. Nature of Operations Ur-Energy Inc. was incorporated on March 22, 2004 under the laws of the Province of Ontario. It was continued under the Canada Business Corporations Act on August 8, 2006 . Ur-Energy Inc. and its wholly-owned subsidiaries Ur-Energy USA Inc.; NFU Wyoming, LLC; Lost Creek ISR, LLC; NFUR Bootheel, LLC; Hauber Project LLC; NFUR Hauber, LLC; and Pathfinder Mines Corporation (collectively, the “Company”) is an exploration stage mining company as defined by U.S. Securities and Exchange Commission (“SEC”) Industry Guide 7. We are headquartered in Littleton, Colorado. The Company is engaged in uranium mining and recovery operations, with activities including acquisition, exploration, development and operations of uranium mineral properties located in Wyoming. The Company commenced uranium production at its Lost Creek Project in August 2013 . Due to the nature of the uranium mining methods we use on the Lost Creek Property, and the definition of “mineral reserves” under the SEC Industry Guide 7, the Company has not determined whether the Lost Creek Property contains mineral reserves. However, the Company’s June 17, 2015 NI 43-101 “ Technical Report for the Lost Creek Property, Sweetwater County, Wyoming, ” outlines the potential viability of the Lost Creek Property. As well, the Company’s January 27, 2015 NI 43-101 Technical Report on Shirley Basin, “ Preliminary Economic Assessment of Shirley Basin Uranium Project Carbon County, Wyoming , USA ” (the “Shirley Basin PEA”), outlines the potential viability of the Shirley Basin Project. The recoverability of amounts recorded for mineral properties is dependent upon the discovery of economic resources, the ability of the Company to obtain the necessary financing to develop the properties and upon attaining future profitable production from the properties or sufficient proceeds from disposition of the properties.

Liquidity Risk

Liquidity Risk	6 Months Ended
	Jun. 30, 2015
Liquidity Risk [Abstract]
Liquidity Risk	2 . Liquidity Risk The Company has financed its operations from its inception primarily through the issuance of equity securities and debt instruments. Construction and development of the Lost Creek Project commenced in October 2012 after receiving the Record of Decision from the U.S. Department of the Interior Bureau of Land Management (“BLM”). Production began in August 2013 after receiving final operational clearance from the U.S. Nuclear Regulatory Commission (“NRC”). The Company made its first deliveries and related sales in December 2013 . It is now generating funds from sales to finance its operations. Based upon the Company’s current working capital balances and the expected timing of contractual product sales, it is possible that additional funding may be sought. During the quarter, the Company accelerated a contractual delivery from September to April and delivered under the contract using purchased U 3 O 8 . Also during the quarter, the Company conducted its first spot priced sale in June and delivered under the sale using produced U 3 O 8 . These are examples of the methods the Company may use to mitigate short term cash flow timing issues utlizing internal resources as opposed to obtaining additional external funding. The Company has no immediate plans to raise debt or equity financing, but may do so in the future. Although the Company has been successful in raising debt and equity financing in the past, there can be no guarantee that such funding will be available in the future.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	3. Summary of Significant Accounting Policies Basis of presentation These financial statements have been prepared by management in accordance with United States generally accepted accounting principles (“US GAAP”) and include all of the assets, liabilities and expenses of the Company. All inter-company balances and transactions between the subsidiaries and/or the parent have been eliminated upon consolidation. These unaudited interim consolidated financial statements do not conform in all respects to the requirements of generally accepted accounting principles for annual financial statements. The unaudited interim financial statements reflect all normal adjustments which in the opinion of management are necessary for a fair statement of the results for the periods presented. These unaudited interim consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements for the year ended December 31, 2014 . Exploration stage The Company has established the existence of uranium resources for certain uranium projects, including the Lost Creek Property. The Company has not established proven or probable reserves, as defined by SEC under Industry Guide 7, through the completion of a final or “bankable” feasibility study for any of its uranium projects, including the Lost Creek Property. Furthermore, the Company has no plans to establish proven or probable reserves for any of its uranium projects for which the Company plans on utilizing in-situ recovery (“ISR”) mining, such as the Lost Creek Project or the Shirley Basin Project. As a result, and despite the fact that the Company commenced recovery of U 3 O 8 at the Lost Creek Project in August 2013 , the Company remains in the Exploration Stage as defined under Industry Guide 7, and will continue to remain in the Exploration Stage until such time proven or probable reserves have been established. Since the Company commenced recovery of uranium at the Lost Creek Project without having established proven and probable reserves, any uranium resources established or extracted from the Lost Creek Project should not be in any way associated with having established, or production from, proven or probable reserves. Accordingly, information concerning mineral deposits set forth herein may not be comparable to information made public by companies that have reserves in accordance with United States standards. Exploration, evaluation and development costs Exploration and evaluation expenses consist of labor, annual exploration lease and maintenance fees and associated costs of the exploration geology department as well as land holding and exploration costs including drilling and analysis on properties which have not reached the permitting or operations stage. Development expense relates to the Company’s Lost Creek, LC East and Shirley Basin projects, which are more advanced in terms of permitting and preliminary economic assessments. Development expenses include all costs associated with exploring, delineating and permitting within those projects, the costs associated with the construction and development of permitted mine units including wells, pumps, piping, header houses, roads and other infrastructure related to the preparation of a mine unit to begin extraction operations as well as the cost of drilling and completing disposal wells. Capital assets Property, plant and equipment assets, including machinery, processing equipment, enclosures, vehicles and expenditures that extend the life of such assets, are recorded at cost including acquisition and installation costs. The enclosure costs include both the building housing and the processing equipment necessary for the extraction of uranium from impregnated water pumped in from the wellfield to the packaging of uranium yellowcake for delivery into sales. These enclosure costs are combined as the equipment and related installation associated with the equipment is an integral part of the structure itself. The costs of self-constructed assets include direct construction costs, direct overhead and allocated interest during the construction phase. Depreciation is calculated using a declining balance method for most assets with the exception of the plant enclosure and related equipment. Depreciation on the plant enclosure and related equipment is calculated on a straight-line basis. Estimated lives for depreciation purposes range from three years for computer equipment and software to 20 years for the plant enclosure and the name plate life of the related equipment. New accounting pronouncements In April 2015 , the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU” ) 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal periods beginning after December 15, 2015 . Early adoption is permitted for financial statements that have not been previously issued. We have elected early adoption of this standard effective with these financial statements. The impact was to move $174 thousand from current deferred loan costs to offset the current portion of the long term debt and to move $638 thousand of deferred loan costs previously included in non-current assets to offset the long term portion of the notes payable as of June 30, 2015 . As at December 31, 2014 , we moved $190 thousand of current deferred cost to offset the current portion of long-term debt and $716 thousand of non-current deferred loan costs to offset non-current notes payable. See note 11. In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers (Topic 606) ”. The amendments in ASU 2014-09 affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards ( e.g., insurance contracts or lease contracts). This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition , and most industry-specific guidance, and creates a Topic 606 Revenue from Contracts with Customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of ptherromised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments were to be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In June 2015, the FASB extended the implementation implementation date for one year to December 15, 2017. Early application is not permitted. The Company does not currently have contracts or other arrangements with customers which would be affected by this Standard. It will continue monitoring the final terms of the standard and assessing any impact on revenue recognition as appropriate.

Mineral Properties The Company’s mineral properties consist of the following : Lost Creek Pathfinder Other US Property Mines Properties Total $ $ $ $ Balance, December 31, 2014 Amortization - - Balance, June 30, 2015 Lost Creek Property The Company acquired certain Wyoming properties in 2005 when Ur-Energy USA Inc. purchased 100% of NFU Wyoming, LLC. Assets acquired in this transaction include the Lost Creek Project, other Wyoming properties and development databases. NFU Wyoming, LLC was acquired for aggregate consideration of $20 million plus interest. Since 2005, the Company has increased its holdings adjacent to the initial Lost Creek acquisition through staking additional claims and additional property purchases and leases. There is a royalty on each of the State of Wyoming sections under lease at the Lost Creek, LC West and EN Projects, as required by law. Other royalties exist on certain mining claims at the LC South and EN Projects. There are no royalties on the mining claims in the Lost Creek, LC North, LC East or LC West Projects. Pathfinder Mines The Company acquired additional Wyoming properties when Ur-Energy USA Inc. closed a Share Purchase Agreement (“SPA”) with an AREVA Mining affiliate in December 2013. Under the terms of the SPA, the Company purchased Pathfinder Mines Corporation (“Pathfinder”). Assets acquired in this transaction include the Shirley Basin Mine Project, portions of the Lucky Mc Mine, machinery and equipment, vehicles, office equipment, and exploration and development databases. Pathfinder was acquired for aggregate consideration of $6.6 million, a 5% production royalty under certain circumstances and the assumption of certain asset reclamation obligations which were estimated by AREVA at $5.7 million. Additional royalties exist on certain of the mineral properties at Shirley Basin as described in the January 2015 Shirley Basin PEA. The purchase price allocation attributed $5.7 million to asset retirement obligations, $3.3 million to deferred tax liabilities, $15.3 million to mineral properties and the balance to the remaining assets and liabilities.

Equity Investment [Abstract]
Equity Investment	9. Equity Investment Following its earn-in to the Bootheel Project in 2009, Jet Metals Corp was required to fund 75% of the project’s expenditures and the Company the remaining 25% . The project has been accounted for using the equity accounting method with the Company’s pro rata share of the project’s loss included in the Statement of Operations since the date of earn-in and the Company’s net investment is reflected on the Balance Sheet. Under the terms of the operating agreement, the Company elected not to participate financially for the year ended June 30, 2012 which reduced the Company’s ownership percentage to approximately 19% . The equity accounting method has been continued because the Company has an equal number of members on the management committee as the other member and can directly influence the budget, expenditures and operations of the project.

Notes Payable [Abstract]
Notes Payable	11. Notes Payable On October 15, 2013, the Sweetwater County Commissioners approved the issuance of a $34.0 million Sweetwater County, State of Wyoming, Taxable Industrial Development Revenue Bond (Lost Creek Project), Series 2013 (the “Sweetwater IDR Bond”) to the State of Wyoming, acting by and through the Wyoming State Treasurer, as purchaser. On October 23, 2013, the Sweetwater IDR Bond was issued and the proceeds were in turn loaned by Sweetwater County to Lost Creek ISR, LLC pursuant to a financing agreement dated October 23, 2013 (the “State Bond Loan”). The State Bond Loan calls for payments of interest at a fixed rate of 5.75% per annum on a quarterly basis commencing January 1, 2014. The principal is payable in 28 quarterly installments commencing January 1, 2015 and continuing through October 1, 2021. The State Bond Loan is collateralized by all of the assets at the Lost Creek Project. As a condition of the financing, earlier loan facilities with RMB Australia Holding Ltd (“RMBAH”) together with certain construction equipment loans were paid off with the funding proceeds from the State Bond Loan. On June 24, 2013, the Company entered into a $20.0 million First Loan Facility with RMBAH. The initial $20.0 million was drawn and repaid during 2013. An amendment to the First Loan Facility allowed for $5.0 million to be redrawn. This was done on December 19, 2013 for the acquisition of Pathfinder. On March 14, 2014, the loan was amended to change the interest rate, extend the loan maturity date to March 31, 2016 and increase the current loan to $10.0 million which included an additional line of credit of $3.5 million as a result of the completion and results of the Technical Report (NI 43-101) on the newly acquired Shirley Basin Project. On March 14, 2014, the Company also drew down an additional $1.5 million on its First Loan Facility. On September 19, 2014, the Company drew down the $3.5 million line of credit. The amended interest rate is approximately 8.75% . Principal payments of $0.81 million are due quarterly. The line of credit is renewable until March 31, 2016. Deferred loan fees includes legal fees, commissions, commitment fees and other costs associated with obtaining the various financings. Those fees amortizable within 12 months of June 30, 2015 are considered current. The current and long-term deferred loan fees have been offset against the related liabilities in accordance with recently approved ASU 2015-03 which we have elected to adopt early in these financial statements See note 3. The following table lists the current (within 12 months) and long term portion of each of the Company’s debt instruments: As at As at June 30, 2015 December 31, 2014 Current debt Sweetwater County bond RMBAH First Loan Facility Less deferred financing costs Long term debt Sweetwater County bond RMBAH First Loan Facility - Less deferred financing costs Schedule of payments on outstanding debt as of June 30, 2015 : Debt Total 2015 2016 2017 2018 2019 Subsequent Maturity Sweetwater County bond Principal October 1, 2021 Interest RMBAH First Loan Facility Principal - - - March 31, 2016 Interest - - - Total

Income taxes and Deferred Income Taxes [Abstract]
Income taxes	12. Income Taxes and Deferred Income Taxes The deferred income tax liability relates to the acquisition of Pathfinder. When the Company acquired Pathfinder, it had no basis in its remaining assets. Accordingly, the Company has no tax basis in these assets. Under US GAAP, the Company has to record a liability for the estimated additional taxes that would arise on the disposition of those assets because of the lack of tax basis in those assets. Based upon the level of historical taxable loss, management believes it is more likely than not that the Company will not realize the benefits of these deductible differences and accordingly has not reflected any deferred income tax assets.

Asset Retirement and Reclamation Obligations Asset retirement obligations ("ARO") relate to the Lost Creek Project and Pathfinder and are equal to the present value of all estimated future costs required to remediate any environmental disturbances that exist as of the end of the period discounted at a risk-free rate. Included in this liability are the costs of closure, reclamation, demolition and stabilization of the mines, processing plants, infrastructure, aquifer restoration, waste dumps and ongoing post-closure environmental monitoring and maintenance costs. At June 30, 2015, the total undiscounted amount of the future cash needs was estimated to be $24.8 million. The schedule of payments required to settle the ARO liability extends through 2033. The restricted cash as discussed in note 6 is related to the surety bonds which provide security to the related governmental agencies on these obligations.

Other Liabilities Warrants	14. Other Liabilities - Warrants For the December 2013 private placement, we issued units consisting of one common share of the Company’s stock and one half warrant. Each full warrant is priced at US $1.35 which created a derivative financial instrument as it is exerciseable in a currency other than the parent company’s functional currency. The liability created is adjusted to a calculated fair value quarterly using the Black-Scholes technique described below as there is no active market for the warrants. Any income or loss is reflected in net income for the year. The revaluation as of June 30, 2015 resulted in gains of $248 and $171 thousand for the three and six months ended June 30, 2015, respectively, which is reflected on the statement of operations.

Shareholders’ Equity and Capital Stock Stock options In 2005, the Company’s Board of Directors approved the adoption of the Company's stock option plan (the “Option Plan”). Eligible participants under the Option Plan include directors, officers, employees and consultants of the Company. Under the terms of the Option Plan, stock options generally vest with Option Plan participants as follows: 10% at the date of grant; 22% four and one-half months after grant; 22% nine months after grant; 22% thirteen and one-half months after grant; and the balance of 24% eighteen months after the date of grant. Activity with respect to stock options is summarized as follows: Weighted- Options average # exercise price US$ Outstanding, December 31, 2014 Granted Exercised Forfeited Expired Outstanding, June 30, 2015 The exercise price of a new grant is set at the closing price for the shares on the Toronto Stock Exchange (TSX) on the trading day immediately preceding the grant date so there is no intrinsic value as of the date of grant. The fair value of options vested during the six months ended June 30, 2015 was $0.4 million. As of June 30, 2015, outstanding stock options are as follows: Options outstanding Options exercisable Weighted- Weighted- average Aggregate average Aggregate Exercise remaining Intrinsic remaining Intrinsic price Number contractual Value Number contractual Value US$ of options life (years) US$ of options life (years) US$ Expiry (thousands) (thousands) 2.32 0.6 - 0.6 - January 28, 2016 1.27 1.0 - 1.0 - July 7, 2016 0.95 1.2 - 1.2 - September 9, 2016 0.94 1.3 - 1.3 - October 24, 2016 0.74 1.5 1.5 January 12, 2017 1.12 1.6 - 1.6 - February 1, 2017 0.95 1.7 - 1.7 - March 1, 2017 0.62 2.4 2.4 December 7, 2017 0.62 2.8 2.8 April 25, 2018 1.00 3.1 - 3.1 - August 1, 2018 0.97 3.5 - 3.5 - December 27, 2018 1.36 3.8 - 3.8 - March 31, 2019 0.83 4.5 - 4.5 - December 12, 2019 0.92 4.9 4.9 May 29, 2020 1.08 2.5 2.2 The aggregate intrinsic value of the options in the preceding table represents the total pre-tax intrinsic value for stock options with an exercise price less than the Company’s TSX closing stock price of Cdn $0.97 as of the last trading day in the period ended June 30, 2015, that would have been received by the option holders had they exercised their options as of that date. The total number of in-the-money stock options outstanding as of June 30, 2015 was 2,748,315 . The total number of in-the-money stock options exercisable as of June 30, 2015 was 2,748,315 . Restricted share units On June 24, 2010, the Company’s shareholders approved the adoption of the Company’s restricted share unit plan (the “RSU Plan”). The plan was approved most recently, as amended, on April 25, 2013. Eligible participants under the RSU Plan include directors and employees of the Company. Under the terms of the original RSU Plan, RSUs vested with participants as follows: 50% on the first anniversary of the date of the grant and 50% on the second anniversary of the date of the grant. In March 2015, the Board approved amendments to the plan that (a) extend the redemption period so that, going forward, all RSUs in a grant are not redeemed until the second anniversary of the grant; (b) provide for redemption, instead of cancellation, of outstanding RSUs at the date of redemption for retiring directors and executive officers, which is defined as a threshold of combined service and age of 65 years, and a minimum of five years of service to the Company; and (c) update the RSU Plan for compliance with applicable laws. The amendments were approved and ratified by shareholder vote at our most recent annual meeting of shareholders. Activity with respect to RSUs is summarized as follows: Number Weighted of average grant RSUs date fair value US$ Unvested, December 31, 2014 Granted Vested Forfeited Unvested, June 30, 2015 As of June 30, 2015, outstanding RSUs are as follows: Aggregate Number of Remaining Intrinsic unvested life Value Grant date RSUs (years) US$ (thousands) December 27, 2013 0.49 December 12, 2014 1.45 March 13, 2015 1.70 1.38 Upon RSU vesting, the holder of an RSU will receive one common share, for no additional consideration, for each RSU held. Warrants There was no warrant activity during the period ended June 30, 2015. As of June 30, 2015, outstanding warrants are as follows: Aggregate Exercise Remaining Intrinsic price Number contractual Value US$ of warrants life (years) US$ Expiry (thousands) 0.92 0.2 - September 4, 2015 1.12 0.3 - November 1, 2015 0.93 0.7 - March 5, 2016 1.35 1.5 - December 19, 2016 1.12 3.0 - June 24, 2018 1.17 3.2 - August 27, 2018 1.19 2.8 - Share-based compensation expense Share-based compensation expense was $0.4 million and $0.6 million for the three and six months ended June 30, 2015, repectively and $0.2 million and $0.6 million for the three and six months ended June 30, 2014, respectively. As of June 30, 2015, there was approximately $0.4 million of total unrecognized compensation expense (net of estimated pre-vesting forfeitures) related to unvested share-based compensation arrangements granted under the Option Plan and $0.4 million under the RSU Plan. The expenses are expected to be recognized over a weighted-average period of 1.0 years and 1.4 years, respectively. Cash received from stock options exercised during the six months ended June 30, 2015 and 2014 was $0.4 million and $0.9 million, respectively. Fair value calculations The fair value of RSUs granted during the six months ended June 30, 2015 was determined using the intrinsic value method using a forfeiture rate of 7.81% based on historical data. The initial fair value of options granted during the six months ended June 30, 2015 and 2014 was determined using the Black-Scholes option pricing model. The following assumptions were used in the calculations: Six months ended June 30, 2015 2014 Expected option life (years) 3.60 3.49 Expected volatility 57.00% 66.00% Risk-free interest rate 0.67% 1.40% Expected dividend rate 0% 0% Forfeiture rate (Options) 5.0% 4.5% The Company estimates expected volatility using daily historical trading data of the Company’s common shares, because this is recognized as a valid method used to predict future volatility. The risk-free interest rates are determined by reference to Canadian Treasury Note constant maturities that approximate the expected option term. The Company has never paid dividends and currently has no plans to do so. Share-based compensation expense is recognized net of estimated pre-vesting forfeitures, which results in recognition of expense on options that are ultimately expected to vest over the expected option term. Forfeitures were estimated using actual historical forfeiture experience. There were no RSUs granted in the six months ended June 30, 2014.

Financial instruments [Abstract]
Financial instruments	17. Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, accounts receivable, restricted cash, deposits, accounts payable and accrued liabilities and notes payable. The Company is exposed to risks related to changes in interest rates and management of cash and cash equivalents and short-term investments. Credit risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash and cash equivalents and restricted cash. These assets include Canadian dollar and U.S. dollar denominated certificates of deposits, money market accounts and demand deposits These instruments are maintained at financial institutions in Canada and the United States. Of the amount held on deposit, approximately $0.5 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation or the United States Federal Deposit Insurance Corporation, leaving approximately $10.9 million at risk at June 30, 2015 should the financial institutions with which these amounts are invested be rendered insolvent. The Company does not consider any of its financial assets to be impaired as of June 30, 2015. All of the Company’s customers have Moody’s Baa or greater ratings and purchase from the Company under contracts for set prices and payment terms. Liquidity risk (see note 2) Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. The Company has financed its operations from inception primarily through the issuance of equity securities and debt instruments. Production commenced in August 2013 after receiving final operational clearance from the NRC. Product sales commenced in December 2013. As at June 30, 2015, the Company’s financial liabilities consisted of trade accounts payable and accrued trade and payroll liabilities of $1.3 million which are due within normal trade terms of generally 30 to 60 days, notes payable which will be payable over periods of 0 to 6.5 years, and asset retirement obligations with estimated completion dates until 2033. Sensitivity analysis The Company has completed a sensitivity analysis to estimate the impact that a change in interest rates would have on the net loss of the Company. This sensitivity analysis shows that a change of +/- 100 basis points in interest rate would have a nominal effect on either the six months ended June 30, 2015 or the six months ended June 30, 2014. The financial position of the Company may vary at the time that a change in interest rates occurs causing the impact on the Company’s results to differ from that shown above.

Summary of Significant Accoun24

Summary of Significant Accounting Policies [Abstract]
Basis of presentation	Basis of presentation These financial statements have been prepared by management in accordance with United States generally accepted accounting principles (“US GAAP”) and include all of the assets, liabilities and expenses of the Company. All inter-company balances and transactions between the subsidiaries and/or the parent have been eliminated upon consolidation. These unaudited interim consolidated financial statements do not conform in all respects to the requirements of generally accepted accounting principles for annual financial statements. The unaudited interim financial statements reflect all normal adjustments which in the opinion of management are necessary for a fair statement of the results for the periods presented. These unaudited interim consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements for the year ended December 31, 2014 .
Capital assets	Capital assets Property, plant and equipment assets, including machinery, processing equipment, enclosures, vehicles and expenditures that extend the life of such assets, are recorded at cost including acquisition and installation costs. The enclosure costs include both the building housing and the processing equipment necessary for the extraction of uranium from impregnated water pumped in from the wellfield to the packaging of uranium yellowcake for delivery into sales. These enclosure costs are combined as the equipment and related installation associated with the equipment is an integral part of the structure itself. The costs of self-constructed assets include direct construction costs, direct overhead and allocated interest during the construction phase. Depreciation is calculated using a declining balance method for most assets with the exception of the plant enclosure and related equipment. Depreciation on the plant enclosure and related equipment is calculated on a straight-line basis. Estimated lives for depreciation purposes range from three years for computer equipment and software to 20 years for the plant enclosure and the name plate life of the related equipment.
New accounting pronouncements	New accounting pronouncements In April 2015 , the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update ("ASU” ) 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. Debt disclosures will include the face amount of the debt liability and the effective interest rate. The update requires retrospective application and represents a change in accounting principle. The update is effective for fiscal periods beginning after December 15, 2015 . Early adoption is permitted for financial statements that have not been previously issued. We have elected early adoption of this standard effective with these financial statements. The impact was to move $174 thousand from current deferred loan costs to offset the current portion of the long term debt and to move $638 thousand of deferred loan costs previously included in non-current assets to offset the long term portion of the notes payable as of June 30, 2015 . As at December 31, 2014 , we moved $190 thousand of current deferred cost to offset the current portion of long-term debt and $716 thousand of non-current deferred loan costs to offset non-current notes payable. See note 11. In May 2014, the FASB issued ASU 2014-09, “ Revenue from Contracts with Customers (Topic 606) ”. The amendments in ASU 2014-09 affect any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards ( e.g., insurance contracts or lease contracts). This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition , and most industry-specific guidance, and creates a Topic 606 Revenue from Contracts with Customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of ptherromised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The amendments were to be effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. In June 2015, the FASB extended the implementation implementation date for one year to December 15, 2017. Early application is not permitted. The Company does not currently have contracts or other arrangements with customers which would be affected by this Standard. It will continue monitoring the final terms of the standard and assessing any impact on revenue recognition as appropriate.
