Nature of Operations

Nature of Operations [Abstract]
Nature of operations	1. Ur-Energy Inc. (the “Company”) was incorporated on March 22, 2004 under the laws of the Province of Ontario. The Company was continued under the Canada Business Corporations Act on August 8, 2006. The Company is an exploration stage mining company, as defined by U. S. Securities and Exchange Commission (“SEC”) Industry Guide 7, headquartered in Littleton, Colorado. The Company is engaged in uranium mining and recovery operations, with activities including the acquisition, exploration, development and production of uranium mineral resources located in Wyoming. As of August 2013, the Company commenced uranium production at its Lost Creek Project in Wyoming. Due to the nature of the uranium mining methods used by the Company on the Lost Creek Property, and the definition of “mineral reserves” under National Instrument 43-101 (“NI 43-101”), which uses the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards, the Company has not determined whether the properties contain mineral reserves. However, the Company’s “ Amended Preliminary Economic Assessment of the Lost Creek Property, Sweetwater County, Wyoming, ” February 8, 2016 (“Lost Creek PEA”) outlines the potential viability of the Lost Creek Property. 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.

Summary of Significant Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Basis of presentation 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, 2015. The year-end balance sheet data was derived from the audited financial statements and certain information and footnote disclosures required by United States generally accepted accounting principles (US GAAP) have been condensed or omitted. New accounting pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 the promised 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 are effective for annual reporting periods beginning after December 15, 2017. Early application is not permitted. We are assessing the impact this pronouncement may have on our financial reporting. In January 2016, the FASB issued ASU 2016-1, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) . The amendments in this ASU supersede the guidance to classify equity securities with readily determinable fair values into different categories (that is, trading or available-for-sale) and require equity securities (including other ownership interests, such as partnerships, unincorporated joint ventures, and limited liability companies) to be measured at fair value with changes in the fair value recognized through net income. The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The amendments also require enhanced disclosures about those investments. The amendments improve financial reporting by providing relevant information about an entity’s equity investments and reducing the number of items that are recognized in other comprehensive income. This guidance is effective for annual reporting beginning after December 15, 2017, including interim periods within the year of adoption, and calls for prospective application, with early application permitted. Accordingly, the standard is effective for us beginning in the first quarter of fiscal 2019. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which requires lessees to recognize all leases, including operating leases, unless the lease is a short-term lease. ASU 2016-02 also requires additional disclosures regarding leasing arrangements. ASU 2016-02 is effective for interim periods and fiscal years beginning after December 15, 2018, and early application is permitted. We are currently evaluating the impact that this standard update will have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation- Improvements to Employee Share-Based Payment Accounting (Topic 718) , which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. In regard to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period, however early adoption is permitted. We are currently evaluating the guidance to determine the Company's adoption method and the effect it will have on the Company's Consolidated Financial Statements.

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, LC East and EN Projects. Currently, there are no royalties on the mining claims in the Lost Creek, LC North 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”) to acquire additional mineral properties. Assets acquired in this transaction include the Shirley Basin mine, portions of the Lucky Mc mine, machinery and equipment, vehicles, office equipment and development databases. Pathfinder was acquired for aggregate consideration of $6.7 million, a 5% production royalty under certain circumstances and the assumption of $5.7 million in estimated asset reclamation obligations . At June 30, 2016, the royalty expired and has been terminated. Other U.S. properties In June 2016, the Company decided to abandon its claims in the Hauber project and wrote off $62 thousand being the carrying value of the investment in that project. No impairment indicators were identified or recorded for any properties other than the investment in Bootheel described below.

Equity Investment [Abstract]
Equity Investment	9. 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 reflected on the Balance Sheet. Under the terms of the operating agreement, the Company elected not to participate financially for the year ended March 31, 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. In 2016, the Company performed quarterly impairment analyses based on the mineralization at the Bootheel property and the then current spot price. It determined that impairments reflecting the then current spot price were warranted. Upon further analysis, it was determined that the deteriorating market conditions have made the investment not currently economically viable. Therefore, while the ownership interest will continue to be carried by the Company and the related resources retained, the Company has elected to write off the remaining basis in the investment as of September 30, 2016 resulting in a charge of $889 for the quarter and $1,089 for the year.

Notes Payable	11. 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. On March 14, 2014, the Company modified a loan facility with RMB to include a $3.5 million line of credit. On October 15, 2015, the loan was amended to extend the maturity date of the $3.5 million line of credit to December 31, 2016 and spread the $3.5 million balance originally due March 31, 2016 over four quarterly payments commencing March 31, 2016 and concluding December 31, 2016, plus interest at a rate of approximately 9.13%. This was considered a modification for accounting purposes. Deferred loan fees include legal fees, commissions, commitment fees and other costs associated with obtaining the various financings. Those fees amortizable within 12 months of September 30, 2016 are considered current.

Asset Retirement Obligations [Abstract]
Asset Retirement and Reclamation Obligations	13. Asset retirement obligations ("ARO") relate to the Lost Creek mine and Pathfinder projects 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 September 30, 2016, the total undiscounted amount of the future cash needs was estimated to be $27.2 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 governmental agencies on these obligations.

Shareholders' Equity and Capital Stock	14. Stock options In 2005, the Company’s Board of Directors approved the adoption of the Company's stock option plan (the “Option Plan”). The plan was most recently approved by the shareholders on April 29, 2014. 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- average Options exercise price # US$ Balance, December 31, 2015 Exercised Forfeited Expired Outstanding, September 30, 2016 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 nine months ended September 30, 2016 was $0.5 million.

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 RSU Plan was approved by our shareholders most recently on May 5, 2016. 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 on May 28, 2015. Grants made subsequent to May 28, 2015 have been made pursuant to the amendments described. Activity with respect to RSUs is summarized as follows: Number Weighted of average grant RSUs date fair value US$ Unvested, December 31, 2015 Vested Forfeited Unvested, September 30, 2016 As of September 30, 2016, outstanding RSUs are as follows: Number of Remaining Aggregate unvested life Intrinsic Grant date RSUs (years) Value US$ (thousands) December 12, 2014 0.20 March 13, 2015 0.45 August 17, 2015 0.88 December 11, 2015 1.20 0.84 Upon RSU vesting, the holder of an RSU will receive one common share, for no additional consideration, for each RSU held. Warrants The following represents warrant activity during the period ended September 30, 2016. Number Weighted- of average Warrants exercise price US$ Outstanding, December 31, 2015 Expired Outstanding, September 30, 2016 As of September 30, 2016, outstanding warrants are as follows: Remaining Aggregate Exercise Number contractual Intrinsic price of warrants life (years) Value Expiry US$ US$ (thousands) 1.35 0.2 - December 19, 2016 0.91 1.7 - June 24, 2018 0.95 1.9 - August 27, 2018 1.04 1.3 - Share-based compensation expense Share-based compensation expense was $0.2 million and $0.6 million for the three and nine months ended September 30, 2016 and $0.2 million and $0.7 million for the three and nine months ended September 30, 2015, respectively. As of September 30, 2016, there was approximately $0.2 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 $0.3 million under the RSU Plan. The expenses are expected to be recognized over a weighted-average period of 0.6 years and 0.9 years, respectively. Cash received from stock options exercised during the nine months ended September 30, 2016 was less than $0.1 million and $0.4 million for the nine months ended September 30, 2015. Fair value calculations The initial fair value of options and RSUs granted is determined using the Black-Scholes option pricing model for options and the intrinsic pricing model for RSUs. There were no options or RSUs granted in the nine months ended September 30, 2016. The following assumptions were used in the calculations: Nine months ended September 30, 2015 Expected option life (years) 3.6 Expected volatility 57.00% Risk-free interest rate 0.67% Expected dividend rate 0% Forfeiture rate (Options) 5.0% Forfeiture rate (RSUs) 7.8% 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.

Financial instruments [Abstract]
Financial instruments	16. 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 $0.6 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation or the United States Federal Deposit Insurance Corporation, leaving approximately $9.9 million at risk at September 30, 2016 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 September 30, 2016. 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 Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they come due. As at September 30, 2016, the Company’s financial liabilities consisted of trade accounts payable and accrued trade and payroll liabilities of $2.4 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 5.0 years, and asset retirement obligations with estimated completion dates until 2033. In February 2016, the Company raised $5.7 million (net of costs of $766 thousand) from the issuance of 12.9 million shares priced at $0.50 per share pursuant to a bought-deal financing. The rationale for raising funds was due to a change in the timing of contracted deliveries and payment commitments in 2016. The Company has relied primarily on cash flow from operations since deliveries from production commenced on a regular basis in 2014. On May 27, 2016, we entered into an At Market Issuance Sales Agreement with MLV & Co. LLC and FBR Capital Markets & Co. under which we may, from time to time, issue and sell common shares at market prices on the NYSE MKT or other U.S. market through the distribution agents for aggregate sales proceeds of up to $10,000,000. Since its inception, we have sold 164,979 common shares under the sales agreement at an average price of $0.65 per share for gross proceeds of $108 thousand. After deducting transaction fees and commissions we received net proceeds of $105 thousand. After deducting all other costs associated with the completion of the agreement and filing the related prospectus supplement, we received $13 thousand. We do not anticipate the need for additional funding in 2016 unless it is advantageous to do so. The Company may continue to consider additional financing opportunities until it builds sufficient cash reserves to cover the variability of cash receipts that result from a limited number of large sales annually which is typical in this industry. Although the Company has been successful in raising debt and equity financing in the past there is no assurance that such financing will be available at all or on terms acceptable to us. 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 three and nine months ended September 30, 2016 or the comparable three and nine months in 2015. 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 Accounting Policies [Abstract]
Basis of presentation	Basis of presentation 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, 2015. The year-end balance sheet data was derived from the audited financial statements and certain information and footnote disclosures required by United States generally accepted accounting principles (US GAAP) have been condensed or omitted.
New accounting pronouncements	New accounting pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 the promised 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 are effective for annual reporting periods beginning after December 15, 2017. Early application is not permitted. We are assessing the impact this pronouncement may have on our financial reporting. In January 2016, the FASB issued ASU 2016-1, Recognition and Measurement of Financial Assets and Financial Liabilities (Topic 825) . The amendments in this ASU supersede the guidance to classify equity securities with readily determinable fair values into different categories (that is, trading or available-for-sale) and require equity securities (including other ownership interests, such as partnerships, unincorporated joint ventures, and limited liability companies) to be measured at fair value with changes in the fair value recognized through net income. The amendments allow equity investments that do not have readily determinable fair values to be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. The amendments also require enhanced disclosures about those investments. The amendments improve financial reporting by providing relevant information about an entity’s equity investments and reducing the number of items that are recognized in other comprehensive income. This guidance is effective for annual reporting beginning after December 15, 2017, including interim periods within the year of adoption, and calls for prospective application, with early application permitted. Accordingly, the standard is effective for us beginning in the first quarter of fiscal 2019. The adoption of this guidance is not expected to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) , which requires lessees to recognize all leases, including operating leases, unless the lease is a short-term lease. ASU 2016-02 also requires additional disclosures regarding leasing arrangements. ASU 2016-02 is effective for interim periods and fiscal years beginning after December 15, 2018, and early application is permitted. We are currently evaluating the impact that this standard update will have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, Compensation-Stock Compensation- Improvements to Employee Share-Based Payment Accounting (Topic 718) , which involves several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under the new standard, income tax benefits and deficiencies are to be recognized as income tax expense or benefit in the income statement and the tax effects of exercised or vested awards should be treated as discrete items in the reporting period in which they occur. An entity should also recognize excess tax benefits regardless of whether the benefit reduces taxes payable in the current period. Excess tax benefits should be classified along with other income tax cash flows as an operating activity. In regard to forfeitures, the entity may make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. This ASU is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period, however early adoption is permitted. We are currently evaluating the guidance to determine the Company's adoption method and the effect it will have on the Company's Consolidated Financial Statements.
