Nature of Operations	'
	1	Nature of Operations
	Ur-Energy Inc. (the “Company”) was incorporated on March 22, 2004 under the laws of the Province of Ontario. The Company 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. We are engaged in the identification, acquisition, exploration, evaluation, development and production of uranium mineral resources located primarily in Wyoming in the United States. As of August 2013, the Company commenced uranium production at its Lost Creek Project.
	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 properties contain mineral reserves. However, the Company’s December 30, 2013 NI 43-101 Technical Report on Lost Creek, “Preliminary Economic Assessment of the Lost Creek Property, Sweetwater County, Wyoming,” 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.

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 United States Department of the Interior Bureau of Land Management (“BLM”).  Production began in August 2013 after receiving final operational clearance from the United States Nuclear Regulatory Commission (“NRC”). The Company made its first deliveries and related sales in December 2013.
	On October 23, 2013, the Company closed a $34 million Sweetwater County, State of Wyoming, Taxable Industrial Development Revenue Bond financing program (“State Bond Loan”)(see note 13). The repayment terms of the State Bond Loan call for interest only payments for the first year of the loan.
	On December 19, 2013, the Company drew down $5 million from RMB Australia Holdings (“RMBAH”) on its First Loan Facility (see note 13). On the same date, the Company closed a private placement for gross proceeds of $5.1 million from the sale of 4.7 million units at $1.10 per unit. Together, the funds were used to purchase Pathfinder Mines Corporation on December 20, 2013.
	On March 14, 2014, the Company drew down an additional $1.5 million on its First Loan Facility (see note 13).
	Based upon the Company’s current working capital balances and the expected timing of product sales, it is possible that additional funding might be sought. 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.

Accounting Changes and Error Corrections [Abstract]	'
Change in Accounting Policy	'
	3	Out of period adjustment
	During the three months ended June 30, 2014, the Company recorded an out of period adjustment to change the treatment of severance and ad valorem taxes from a direct reduction of sales to a cost of extraction which is included in inventory and cost of sales calculations. The adjustment increased sales for the year and quarter by $0.7 million for taxes treated as a direct reduction of sales in prior periods and increased cost of goods sold by $0.5 million. The net effect of the change is an increase in inventory and a decrease of net loss of $0.2 million as of June 30, 2014 and for the three and six month periods then ended. We have concluded that these adjustments were not material to the 2013 or first quarter 2014 results of operations and balance sheets.

Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	4	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 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. All inter-company balances and transactions have been eliminated upon consolidation. Ur-Energy Inc. and its wholly-owned subsidiaries are collectively referred to herein as the “Company.”
	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, 2013.
	Presentation currency
	As a result of losing its foreign private issuer status, the Company previously changed its presentational currency from the Canadian dollar to U.S. dollars. Comparative information has therefore been restated in U.S. dollars in these financial statements. The effects of doing so are not significant because the Canadian and U.S. dollars were close to par at June 30, 2013.
	Exploration Stage
	The Company has established the existence of mineral resources under CIM Definition Standards 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 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 property or the Shirley Basin mine. As a result, and despite the fact that the Company commenced extraction of U3O8 at the Lost Creek property 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 extraction of uranium at the Lost Creek property without having established proven and probable reserves, any uranium established or extracted from the Lost Creek property 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.
	Restatement
	The Company has regularly monitored practices followed by peer companies in the industry. As discussed above, the Company has not established, and has no plans to establish the existence of proven and probable reserves at the Lost Creek Project. As a result of this, the Company changed its accounting policy at December 31, 2013 with respect to the nature of items that qualify for capitalization for in-situ uranium mining operations to align its policy to the accounting treatment that has been established as best practice for these types of mining operations.
	The specific costs affected by this change are those associated with the development of the wellfield which, during 2013, was being constructed as a part of the Lost Creek project.  The development of this wellfield includes production and monitor well drilling and completion, piping within the wellfield and to the processing facility, header houses used to monitor production and disposal wells associated with the operation of the mine.  These costs are now expensed when incurred.
	During the three and six months ended June 30, 2013, a total of $5.8 million and $10.0 million, respectively, of such expenditures was originally capitalized as part of construction in progress within capital assets. Accordingly, the comparative financial statements have been restated to show the impact of this change in accounting policy and include these amounts in development expense. This increased the loss per share from $0.03 per share to $0.08 for the three months and from $0.06 to $0.14 for the six months ended June 30, 2013.
	New accounting pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual periods beginning on or after December 15, 2016. We are still considering whether or not this pronouncement will have an effect our financial statements.

	Lost Creek Property
	The Company acquired certain Wyoming properties when Ur-Energy USA Inc. entered into the Membership Interest Purchase Agreement (“MIPA”) with New Frontiers Uranium, LLC in 2005.  Under the terms of the MIPA, the Company 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 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, 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. 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.
	Canadian properties
	The claims at Screech Lake reached a point during 2014 where the Company needed to take the property to lease under the mining regulations and invest in additional exploration or release the claims. The Company elected not to pursue further exploration at Screech Lake. As a result, the claims were abandoned and the cost of the asset was written off.

	Following its earn-in to the Bootheel Project in 2009, Jet Metals Corp (“Jet Metals”), formerly Crosshair Energy Corporation, 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 proportionate 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 March 31, 2012 which reduced the Company’s ownership percentage to approximately 19%. The equity accounting method has been continued because of the Company’s ability to directly influence the budget process and therefore the operations of the Project. The Company resumed participation financially as of the project year ended March 31, 2013.

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, the RMBAH First and Second Loan Facilities 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 existing loan facility was amended to change the interest rate, extend the loan maturity date to June 30, 2016, increase the current loan to $6.5 million and provide for an additional line of credit of $3.5 million pending the completion and results of the Technical Report (NI 43-101) on the newly acquired Shirley Basin property. The amended interest rate is approximately 8.75%. Principal payments of $0.81 million are due quarterly commencing on June 30, 2014.
	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, 2014 are considered current assets.

	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 basis in those assets.

	In March 2013, the Company assigned a portion of its contractual delivery obligations under two of its sales contracts to a natural resources trading company in exchange for a cash payment of $5.1 million. The remainder of the Company’s contractual delivery obligations under the two contracts remain in place as well as certain other performance obligations including scheduled deliveries of product sourced from approved locations which are covenants associated with the contracts.  The Company reflects a portion of the payment as revenue when the related deliveries under the contracts are settled. As of December 31, 2013, the deliveries called for in 2013 had been made and the revenue thereon was recognized. As of June 30, 2014, one of the two remaining deliveries called for in 2014 had been made and the revenue thereon was recognized. The final required delivery has not been made as of June 30, 2014 and the revenue thereon remains deferred.

	Asset retirement obligations ("ARO") relate to the Lost Creek Project and Pathfinder mines 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, 2014, the total undiscounted amount of the future cash needs was estimated to be $17.7 million. The schedule of payments required to settle the ARO liability extends through 2033.
	The restricted cash as discussed in note 8 is related to the surety bonds and letters of credit which provide security to the related governmental agencies on these obligations.

	For the December 2013 private placement, the Company issued units consisting of one common share and one half warrant. Each full warrant is priced at US$1.35 which created a derivative financial instrument. The liability created is adjusted to a calculated fair value quarterly using the Black-Scholes technique described below. We are using “Level 3” value as there is no active market for the warrants or more accurate external method of measurement. Any income or loss is reflected in net income for the year. The revaluation as of June 30, 2014 resulted in a gain of $576 thousand for the six months ended June 30, 2014 which is reflected on the statement of operations.

Share-based compensation expense
Share-based compensation expense was $0.5 million and $0.4 million for the six months ended June 30, 2014 and 2013, respectively.
As of June 30, 2014, there was approximately $0.5 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 0.9 years and 1.3 years, respectively.
Cash received from stock options exercised during the six months ended June 30, 2014 was $0.9 million. There were no options exercised during the six months ended June 30, 2013.
Fair Value Calculations
The initial fair value of options granted during the six months ended June 30, 2014 was determined using the Black-Scholes option pricing model with the following assumptions:
		2014				2013
Expected option life (years)			3.49				3.41
Expected volatility			66	%			63	%
Risk-free interest rate			1.4	%			1.1	%
Forfeiture rate (options)			4.5	%			4.4	%
Expected dividend rate			0	%			0	%
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 or 2013.

	In June 2014, the Wyoming Department of Environmental Quality and the NRC approved modifications to several reclamation bonds to reflect current obligations and anticipated disturbances during the upcoming year. The total reclamation bonding requirements were therefore increased to $26.7 million. The Company increased its surety performance bonding to that amount. The Company will be increasing the cash securing the security bonds (see note 5) by $3.1 million prior to the end of the current year.
	In June, the Company signed an agreement for drilling and completion of a third disposal well. The project will begin in July 2014 with completion later this year. It is anticipated that the total cost of the well will be approximately $3.2 million.

	21	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 foreign currency exchange rates, interest rates and management of cash and cash equivalents.
	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. They bear interest at annual rates ranging from 0.18% to 0.6% and mature at various dates up to February 5, 2015. These instruments are maintained at financial institutions in Canada and the United States. Of the amount held on deposit, approximately $0.9 million is covered by the Canada Deposit Insurance Corporation, the Securities Investor Protection Corporation or the United States Federal Deposit Insurance Corporation, leaving approximately $5.8 million at risk at June 30, 2014 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, 2014.
	Liquidity risk
	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 its 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, 2014, the Company’s financial liabilities consisted of trade accounts payable and accrued trade and payroll liabilities of $2.8 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 7 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 for 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.

	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 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. All inter-company balances and transactions have been eliminated upon consolidation. Ur-Energy Inc. and its wholly-owned subsidiaries are collectively referred to herein as the “Company.”
	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, 2013.
Presentation currency	'
	Presentation currency
	As a result of losing its foreign private issuer status, the Company previously changed its presentational currency from the Canadian dollar to U.S. dollars. Comparative information has therefore been restated in U.S. dollars in these financial statements. The effects of doing so are not significant because the Canadian and U.S. dollars were close to par at June 30, 2013.
Exploration Stage	'
	Exploration Stage
	The Company has established the existence of mineral resources under CIM Definition Standards 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 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 property or the Shirley Basin mine. As a result, and despite the fact that the Company commenced extraction of U3O8 at the Lost Creek property 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 extraction of uranium at the Lost Creek property without having established proven and probable reserves, any uranium established or extracted from the Lost Creek property 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.
Restatement	'
	Restatement
	The Company has regularly monitored practices followed by peer companies in the industry. As discussed above, the Company has not established, and has no plans to establish the existence of proven and probable reserves at the Lost Creek Project. As a result of this, the Company changed its accounting policy at December 31, 2013 with respect to the nature of items that qualify for capitalization for in-situ uranium mining operations to align its policy to the accounting treatment that has been established as best practice for these types of mining operations.
	The specific costs affected by this change are those associated with the development of the wellfield which, during 2013, was being constructed as a part of the Lost Creek project.  The development of this wellfield includes production and monitor well drilling and completion, piping within the wellfield and to the processing facility, header houses used to monitor production and disposal wells associated with the operation of the mine.  These costs are now expensed when incurred.
	During the three and six months ended June 30, 2013, a total of $5.8 million and $10.0 million, respectively, of such expenditures was originally capitalized as part of construction in progress within capital assets. Accordingly, the comparative financial statements have been restated to show the impact of this change in accounting policy and include these amounts in development expense. This increased the loss per share from $0.03 per share to $0.08 for the three months and from $0.06 to $0.14 for the six months ended June 30, 2013.
New accounting pronouncements	'
	New accounting pronouncements
	In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers. Under ASU 2014-09, an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance is effective for annual periods beginning on or after December 15, 2016. We are still considering whether or not this pronouncement will have an effect our financial statements.
