Summary Of Significant Accounting Policies [Abstract] |
Basis of consolidation [Policy Text Block] | (i) Basis of consolidation The Company consolidates an entity when it has power over that entity, is exposed, or has rights, to variable returns from its involvement with that entity and has the ability to affect those returns through its power over that entity. The financial statements of subsidiaries are consolidated from the date that control commences until the date that control ceases. All significant intercompany transactions and balances are eliminated. The consolidated financial statements of the Company include Western Copper and Gold Corp., Casino Mining Corp., and Ravenwolf Resource Group Ltd.
Presentation currency [Policy Text Block] | (ii) Presentation currency The Company's presentation currency is the Canadian dollar ("$"). The functional currency of Western and its significant subsidiaries is the Canadian dollar.
Foreign currency translation [Policy Text Block] | (iii) Foreign currency translation In preparing the financial statements of the individual entities, transactions in currencies other than the entity's functional currency ("foreign currencies") are recorded at the rates of exchange prevailing at the dates of the transactions. At each balance sheet date, foreign currency denominated monetary assets and liabilities are translated using the period end foreign exchange rate. Non-monetary assets and liabilities are translated using the historical rate on the date of the transaction. All gains and losses on translation of these foreign currency transactions are included in the statement of loss.
Share-based payments [Policy Text Block] | (iv) Share-based payments The Company grants stock options, restricted share units ("RSUs") and deferred share units ("DSUs") to buy common shares of the Company to directors, officers, employees and consultants. The fair value of stock options granted by the Company is treated as compensation costs in accordance with IFRS 2 - Share-based Payments. The fair value of stock options is calculated using the Black-Scholes option pricing model and the fair value of RSUs and DSUs are determined based on the closing price of the shares on the day of grant. These costs are charged to the statement of loss or, if appropriate, are capitalized to exploration and evaluation assets over the stock option vesting period with an offsetting entry to contributed surplus. The Company's allocation of share-based payments is consistent with its treatment of other types of compensation for each recipient. If the stock options are exercised, the value attributable to the stock options is transferred to share capital.
Income taxes [Policy Text Block] | (v) Income taxes Income tax expense consists of current and deferred tax expense. Income tax expense is recognized in the statement of loss. Current tax expense is the expected tax payable on the taxable income for the period, using tax rates enacted or substantively enacted at year end, adjusted for amendments to tax payable with regards to the previous year. Deferred taxes are recorded using the liability method. Under the liability method, deferred tax assets and liabilities are recognized for future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases (i.e. timing differences). Deferred tax assets and liabilities are measured using the enacted or substantively enacted tax rates expected to apply when the asset is realized or the liability settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the statement of loss in the period that the substantive enactment occurs. A deferred tax asset is recognized to the extent that it is probable that future taxable profits will be available against which the asset can be utilized.
Loss per share [Policy Text Block] | (vi) Loss per share Basic loss per share is computed by dividing the net loss available to common shareholders by the weighted average number of shares outstanding during the reporting period. Diluted loss per share is computed in the same way as basic loss per share except that the weighted average number of shares outstanding is increased to include additional shares for the assumed exercise of all stock options and warrants, if dilutive.
Long-lived assets [Policy Text Block] | (vii) Long-lived assets 1. Exploration and evaluation assets Direct costs related to the acquisition and exploration of mineral properties held or controlled by the Company are capitalized on an individual property basis until the property is put into production, sold, abandoned, or determined to be impaired. Administration costs and general exploration costs are expensed as incurred. When a property is placed into commercial production, deferred costs will be depleted using the units-of-production method. The Company classifies its mineral properties as exploration and evaluation assets until technical feasibility and commercial viability of extracting a mineral resource are demonstrable. At this point, the exploration and evaluation assets are transferred to property and equipment. The establishment of technical feasibility and commercial viability of a mineral property is assessed based on a combination of factors, such as the extent of established mineral reserves, the results of feasibility and technical evaluations, and the status of mining leases or permits. Proceeds received from the sale of royalties, tax credits, or government assistance programs are recognized as a reduction in the carrying value of the related asset when the proceeds are more likely than not to be received. If proceeds received is in excess of the carrying value of the related asset after impairment the amount received is recorded as a credit in the statement of loss in the period in which the payment is more likely than not to be received. Although we have taken steps to verify title to mineral properties in which we have an interest, in accordance with industry standards for the current stage of exploration of such properties, these procedures do not guarantee our title. Property title may be subject to unregistered prior agreements or transfers, and may be affected by undetected defects. 2. Leases Leases are recognized as a right-of-use asset and a corresponding liability at the date at which the leased asset is available for use by the Company. Each lease payment is allocated between the liability and finance expense. The finance expense is charged to the statements of operations over the lease period. The right-of-use asset is depreciated over the shorter of the asset's useful life or the lease term on a straight-line basis. Assets and liabilities arising from a lease are initially measured on a present value of lease payments. The lease payments are discounted using the interest rate implicit in the lease, if that rate can be determined, or the Company's incremental borrowing rate. 3. Impairment The Company's exploration and evaluation assets are reviewed for indication of impairment at each balance sheet date in accordance with IFRS 6 - Exploration for and evaluation of mineral resources. If any such indication exists, an estimate of the recoverable amount is undertaken. Recoverable amount is the higher of an asset's fair value less costs of disposal and value in use ("VIU"). If the asset's carrying amount exceeds its recoverable amount then an impairment loss is recognized in the statement of loss. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value of mineral assets is generally determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset, including any expansion prospects. VIU is determined as the present value of the estimated future cash flows expected to arise from the continued use of the asset in its present form and from its ultimate disposal. Impairment is normally assessed at the level of cash-generating units, which are identified as the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets. 4. Reversal of impairment An impairment loss is reversed if there is an indication that there has been a change in the estimates used to determine the recoverable amount. An impairment loss is reversed only to the extent that the asset's carrying amount does not exceed the carrying amount that would have been determined, net of amortization, if no impairment loss had been recognized.
Cash and cash equivalents [Policy Text Block] | (viii) Cash and cash equivalents Cash and cash equivalents consist of cash on hand, deposits in banks and highly liquid investments with an original maturity of three months or less.
Financial instruments [Policy Text Block] | (ix) Financial instruments 1. Classification and measurement Financial instruments are recognized when the Company becomes party to a contractual obligation. At initial recognition, the Company classifies its financial instruments as one the following categories: at fair value through profit and loss ("FVTPL"), at fair value through other comprehensive income ("FVTOCI"), or at amortized cost according to the financial instruments' contractual cash flow characteristics and the business models under which they are held. Financial assets are measured at amortized cost if they are held for the collection of contractual cash flows where those cash flows solely represent payments of principal and interest. The Company's intent is to hold these financial assets in order to collect contractual cash flows and the contractual terms give rise to cash flows on specified dates that are solely payments of principal and interest on the principal amount outstanding. The Company determines the classification of financial assets at initial recognition. Marketable securities are instruments held for trading and are classified as fair value through profit and loss ("FVTPL"). Financial assets are measured at FVTOCI if they are held for the collection of contractual cash flows and for selling the financial assets, where the assets' cash flows represent solely payments of principal and interest. The Company initially recognizes these financial assets at their fair value with subsequent changes to fair values recognized in OCI. When the financial asset is derecognised, the cumulative gain or loss previously recognised in OCI is reclassified from equity to the statement of loss. Financial assets are measured at FVTPL if they do not qualify as financial assets at amortized cost or FVTOCI. The Company initially recognizes these financial assets at their fair value with subsequent changes to fair values recognized in the statement of loss. Financial liabilities are measured at amortised cost unless they are required to be measured at FVTPL. The Company classifies its financial instruments as follows:
Financial assets/liabilities | Classification
Cash and cash equivalents | Amortized cost
Short-term investments | Amortized cost
Marketable securities | FVTPL
Other assets | Amortized cost
Accounts payable and accrued liabilities | Amortized cost
2. Impairment of financial assets At each reporting date, the Company assesses the expected credit loss associated with its financial assets carried at amortized cost and FVTOCI. The impairment methodology applied depends on whether there has been a significant increase in credit risk. Allowances are recognized as impairment gains or losses on the statement of loss. 3. Derecognition Financial assets are derecognized when the rights to receive cash flows from the financial assets have expired or have been transferred and the Company has transferred substantially all the risks and rewards of ownership. Financial liabilities are derecognized when, and only when, the Company's obligations are discharged, cancelled or they expire.
Provisions [Policy Text Block] | (x) Provisions Provisions are recorded when a present legal or constructive obligation exists as a result of past events where it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate of the amount of the obligation can be made. The amount recognized as a provision is the best estimate of the consideration required to settle the present obligation at the balance sheet date, taking into account the risks and uncertainties surrounding the obligation. Where a provision is measured using the cash flows estimated to settle the present obligation, its carrying amount is the present value of those cash flows.
