Notes to Financial Statements
Business Description and Basis of Presentation [Text Block]	NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation These consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and are presented in United States dollars. All inter-company transactions and balances have been eliminated upon consolidation. Exploration Stage We have established the existence of mineralized materials for certain uranium projects, including the Palangana Mine. We have not 7, no November 2010, 7 Since we commenced extraction of mineralized materials at the Palangana Mine without having established proven or probable reserves, any mineralized materials established or extracted from the Palangana Mine should not In accordance with U.S. GAAP, expenditures relating to the acquisition of mineral rights are initially capitalized as incurred while exploration and pre-extraction expenditures are expensed as incurred until such time we exit the Exploration Stage by establishing proven or probable reserves. Expenditures relating to exploration activities, such as drill programs to establish mineralized materials, are expensed as incurred. Expenditures relating to pre-extraction activities such as the construction of mine wellfields, ion exchange facilities and disposal wells, are expensed as incurred until such time proven or probable reserves are established for that project, after which expenditures relating to mine development activities for that particular project are capitalized as incurred. Companies in the Production Stage as defined under Industry Guide 7, no may not Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reported periods. Significant areas requiring management's estimates and assumptions include valuation and measurement of impairment losses on mineral rights and properties, valuation of stock-based compensation and asset retirement obligations. Other areas requiring estimates include allocations of expenditures to inventories, depletion and amortization of mineral rights and properties and depreciation of property, plant and equipment. Actual results could differ significantly from those estimates and assumptions. Foreign Currency Translation The functional currency of our Company, including its subsidiaries, is the United States dollar. Our subsidiaries, UEC Resources Ltd., UEC Resources (SK) Ltd. and Cue Resources Ltd., maintain their accounting records in their local currency, the Canadian dollar. Piedra Rica Mining S.A., Transandes Paraguay S.A., MYNM, Trier S.A. and other Paraguayan subsidiaries maintain their accounting records in their local currency, the Paraguayan Guarani. In accordance with ASC 830: Cash and Cash Equivalents Cash and cash equivalents consist of cash balances and term deposits with an original maturity of three Term Deposits Term deposits include short-term deposits held with banks with maturities from three one Equity-Accounted Investments Investments in an entity in which our ownership is greater than 20% 50%, 323: Other Non-Current Assets Other non-current assets include future expenditures that we have paid in advance but will not one not Mineral Rights Acquisition costs of mineral rights are initially capitalized as incurred while exploration and pre-extraction expenditures are expensed as incurred until such time proven or probable reserves, as defined by the SEC under Industry Guide 7, Where proven and probable reserves have been established, in accordance with Industry Guide 7, not not Databases Expenditures relating to mineral property databases are capitalized upon acquisition while those developed internally are expensed as incurred. Mineral property databases are amortized using the straight-line method over a five Property, Plant and Equipment Property, plant and equipment are recorded at cost and depreciated to their estimated residual values using the straight-line method over their estimated useful lives, as follows: ● Hobson processing facility: 20 ● Mining and logging equipment and vehicles: 5 10 ● Computer equipment: 3 ● Furniture and fixtures: 5 ● Building: 20 Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not not not Income Taxes We account for income taxes under the asset and liability method which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities. We provide a valuation allowance on deferred tax assets unless it is more likely than not Restoration and Remediation Costs (Asset Retirement Obligations) Various federal and state mining laws and regulations require our Company to reclaim the surface areas and restore underground water quality to the pre-existing quality or class of use after the completion of mining. We recognize the present value of the future restoration and remediation costs as an asset retirement obligation in the period in which we incur an obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. Asset retirement obligations consist of estimated final well closure, plant and equipment decommissioning and removal and environmental remediation costs to be incurred by our Company in the future. The asset retirement obligation is estimated based on the current costs escalated at an inflation rate and discounted at a credit adjusted risk-free rate. The asset retirement obligations are capitalized as part of the costs of the underlying assets and amortized over its remaining useful life. The asset retirement obligations are accreted to an undiscounted value until they are settled. The accretion expenses are charged to earnings and the actual retirement costs are recorded against the asset retirement obligations when incurred. Any difference between the recorded asset retirement obligations and the actual retirement costs incurred will be recorded as a gain or loss in the period of settlement. Long- T erm Debt Long-Term Debt is carried at amortized cost. Debt issuance costs, debt premiums and discounts and annual fees are included in the long-term debt balance and amortized using the effective interest rate over the contractual terms of the Long-Term Debt. Leases We determine if a contractual arrangement represents or contains a lease at inception. Operating leases with lease terms greater than 12 Operating and finance lease ROU assets and lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date. When the rate implicit to the lease cannot be readily determined, we utilize the incremental borrowing rate in determining the present value of the future lease payments. The incremental borrowing rate is the rate of interest our Company would have to pay to borrow on a collateralized basis over a similar term and the amount equal to the lease payments in a similar economic environment. The operating lease expenses are recognized on a straight-line basis over the lease term and included in general and administration expenses. Short-term leases, which have an initial term of 12 not We have leases arrangements that include both lease and non-lease components. We account for each separate lease component and its associated non-lease components as a single lease component for all of our asset classes. Stock-Based Compensation We measure stock-based awards at fair value on the date of the grant and expense the awards in our Consolidated Statements of Operations and Comprehensive Loss over the requisite service period of employees or consultants. The fair value of stock options is determined using the Black-Scholes valuation model. The fair value of restricted stock units (“RSU”s) is determined using the share price of the Company at the date of grant. The fair value of performance based restricted stock units (“PRSU”s) is determined using the Monte Carlo simulation model. Stock-based compensation expense related to stock option awards is recognized over the requisite service period on an accelerating basis. Forfeitures are accounted for as they occur.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation and Principles of Consolidation These consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) and are presented in United States dollars. All inter-company transactions and balances have been eliminated upon consolidation.
Exploratory Drilling Costs Capitalization and Impairment, Policy [Policy Text Block]	Exploration Stage We have established the existence of mineralized materials for certain uranium projects, including the Palangana Mine. We have not 7, no November 2010, 7 Since we commenced extraction of mineralized materials at the Palangana Mine without having established proven or probable reserves, any mineralized materials established or extracted from the Palangana Mine should not In accordance with U.S. GAAP, expenditures relating to the acquisition of mineral rights are initially capitalized as incurred while exploration and pre-extraction expenditures are expensed as incurred until such time we exit the Exploration Stage by establishing proven or probable reserves. Expenditures relating to exploration activities, such as drill programs to establish mineralized materials, are expensed as incurred. Expenditures relating to pre-extraction activities such as the construction of mine wellfields, ion exchange facilities and disposal wells, are expensed as incurred until such time proven or probable reserves are established for that project, after which expenditures relating to mine development activities for that particular project are capitalized as incurred. Companies in the Production Stage as defined under Industry Guide 7, no may not
Use of Estimates, Policy [Policy Text Block]	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported revenues and expenses during the reported periods. Significant areas requiring management's estimates and assumptions include valuation and measurement of impairment losses on mineral rights and properties, valuation of stock-based compensation and asset retirement obligations. Other areas requiring estimates include allocations of expenditures to inventories, depletion and amortization of mineral rights and properties and depreciation of property, plant and equipment. Actual results could differ significantly from those estimates and assumptions.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign Currency Translation The functional currency of our Company, including its subsidiaries, is the United States dollar. Our subsidiaries, UEC Resources Ltd., UEC Resources (SK) Ltd. and Cue Resources Ltd., maintain their accounting records in their local currency, the Canadian dollar. Piedra Rica Mining S.A., Transandes Paraguay S.A., MYNM, Trier S.A. and other Paraguayan subsidiaries maintain their accounting records in their local currency, the Paraguayan Guarani. In accordance with ASC 830:
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and Cash Equivalents Cash and cash equivalents consist of cash balances and term deposits with an original maturity of three

Mineral Rights,Policy [PolicyTextBlock]	Mineral Rights Acquisition costs of mineral rights are initially capitalized as incurred while exploration and pre-extraction expenditures are expensed as incurred until such time proven or probable reserves, as defined by the SEC under Industry Guide 7, Where proven and probable reserves have been established, in accordance with Industry Guide 7, not not
Databases [Policy Text Block]	Databases Expenditures relating to mineral property databases are capitalized upon acquisition while those developed internally are expensed as incurred. Mineral property databases are amortized using the straight-line method over a five
Property, Plant and Equipment, Policy [Policy Text Block]	Property, Plant and Equipment Property, plant and equipment are recorded at cost and depreciated to their estimated residual values using the straight-line method over their estimated useful lives, as follows: ● Hobson processing facility: 20 ● Mining and logging equipment and vehicles: 5 10 ● Computer equipment: 3 ● Furniture and fixtures: 5 ● Building: 20
Impairment or Disposal of Long-Lived Assets, Including Intangible Assets, Policy [Policy Text Block]	Impairment of Long-Lived Assets Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not not not
Income Tax, Policy [Policy Text Block]	Income Taxes We account for income taxes under the asset and liability method which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and tax bases of assets and liabilities. We provide a valuation allowance on deferred tax assets unless it is more likely than not
Asset Retirement Obligation [Policy Text Block]	Restoration and Remediation Costs (Asset Retirement Obligations) Various federal and state mining laws and regulations require our Company to reclaim the surface areas and restore underground water quality to the pre-existing quality or class of use after the completion of mining. We recognize the present value of the future restoration and remediation costs as an asset retirement obligation in the period in which we incur an obligation associated with the retirement of tangible long-lived assets that result from the acquisition, construction, development and/or normal use of the assets. Asset retirement obligations consist of estimated final well closure, plant and equipment decommissioning and removal and environmental remediation costs to be incurred by our Company in the future. The asset retirement obligation is estimated based on the current costs escalated at an inflation rate and discounted at a credit adjusted risk-free rate. The asset retirement obligations are capitalized as part of the costs of the underlying assets and amortized over its remaining useful life. The asset retirement obligations are accreted to an undiscounted value until they are settled. The accretion expenses are charged to earnings and the actual retirement costs are recorded against the asset retirement obligations when incurred. Any difference between the recorded asset retirement obligations and the actual retirement costs incurred will be recorded as a gain or loss in the period of settlement.
Debt, Policy [Policy Text Block]	Long- T erm Debt Long-Term Debt is carried at amortized cost. Debt issuance costs, debt premiums and discounts and annual fees are included in the long-term debt balance and amortized using the effective interest rate over the contractual terms of the Long-Term Debt.
Lessee, Leases [Policy Text Block]	Leases We determine if a contractual arrangement represents or contains a lease at inception. Operating leases with lease terms greater than 12 Operating and finance lease ROU assets and lease liabilities are recognized based on the present value of the future lease payments over the lease term at the commencement date. When the rate implicit to the lease cannot be readily determined, we utilize the incremental borrowing rate in determining the present value of the future lease payments. The incremental borrowing rate is the rate of interest our Company would have to pay to borrow on a collateralized basis over a similar term and the amount equal to the lease payments in a similar economic environment. The operating lease expenses are recognized on a straight-line basis over the lease term and included in general and administration expenses. Short-term leases, which have an initial term of 12 not We have leases arrangements that include both lease and non-lease components. We account for each separate lease component and its associated non-lease components as a single lease component for all of our asset classes.
Share-based Payment Arrangement [Policy Text Block]	Stock-Based Compensation We measure stock-based awards at fair value on the date of the grant and expense the awards in our Consolidated Statements of Operations and Comprehensive Loss over the requisite service period of employees or consultants. The fair value of stock options is determined using the Black-Scholes valuation model. The fair value of restricted stock units (“RSU”s) is determined using the share price of the Company at the date of grant. The fair value of performance based restricted stock units (“PRSU”s) is determined using the Monte Carlo simulation model. Stock-based compensation expense related to stock option awards is recognized over the requisite service period on an accelerating basis. Forfeitures are accounted for as they occur. The Company's estimates may not
