Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are

re-measured.

Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rate of exchange in effect at the reporting date.

Non-monetary

items that are measured in terms of historical cost in a foreign currency are translated using the exchange rate as at the date of the initial transaction. Translation gains or losses are recognized in profit or loss.

These consolidated financial statements include the accounts of the Company and its subsidiaries: NXE Energy Royalty Ltd., NXE Energy SW1 Ltd., NXE Energy SW3 Ltd. and IsoEnergy. Shares of IsoEnergy were issued to third parties as part of financings since its inception, thereby resulting in the recognition of

non-controlling

interests. The financial results of the subsidiaries are included in these consolidated financial statements from the date of incorporation. Intercompany balances and transactions are eliminated on consolidation. The following table sets forth the Company’s ownership percentage in each of its subsidiaries as of December 31, 2019:

Once the legal rights to explore a property have been obtained, exploration and evaluation costs are capitalized as exploration and evaluation assets on an area of interest basis pending determination of the technical feasibility and the commercial viability of the project. Capitalized costs include costs directly related to exploration and evaluation activities in the area of interest. When a claim is relinquished or a project is abandoned, the related costs are recognized in profit or loss immediately.

Proceeds received from the sale of any interest in a property will be credited against the carrying value of the property, with any excess included in operations for the period. If a property is abandoned, the acquisition and deferred exploration costs will be written off to operations.

Although the Company has taken steps to verify title to exploration and evaluation assets in which it has an interest, in accordance with industry standards for the current stage of exploration of such properties, these procedures do not guarantee the Company’s title. A property may be subject to unregistered prior agreements or inadvertent

non-compliance

with regulatory requirements.

Once the technical feasibility and commercial viability of the extraction of mineral resources in an area of interest are demonstrable, exploration and evaluation assets attributable to that area of interest are first tested for impairment and then reclassified to mining assets and development assets within property, plant and equipment.

The cost of replacing a part of an item in the carrying amount of equipment is recognized when that cost is incurred, if it is probable that the future economic benefits embodied within the item will flow to the Company and the cost of the item can be measured reliably.

The carrying amounts of equipment (including initial and subsequent capital expenditures) are amortized to their estimated residual value over the estimated useful lives of the specific assets concerned. Depreciation is calculated over the estimated useful lives of each significant component as follows:

An impairment loss is recognized when the carrying amount of an asset, or its cash generating unit (“CGU”), exceeds its recoverable amount. A CGU is the smallest identifiable group of assets that generates cash inflows that are largely independent of the cash inflows from other assets or groups of assets. Impairment losses are recognized in profit and loss for the period. Impairment losses recognized in respect of CGUs are allocated first to reduce the carrying amount of any goodwill allocated to CGUs and then to reduce the carrying amount of the other assets in the unit on a

pro-rata

basis.

The recoverable amount of assets is the greater of an asset’s fair value less cost to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a

pre-tax

discount rate that reflects the current market assessments of the time value of money and the risks specific to the asset. For an asset that does not generate cash inflows largely independent of those from other assets, the recoverable amount is determined for the cash-generating unit to which the asset belongs.

An impairment loss is only reversed if there is an indication that the impairment loss may no longer exist and there has been a change in the estimates used to determine the recoverable amount, however, not to an amount higher than the carrying amount that would have been determined had no impairment loss been recognized in previous years.

Decommissioning and restoration 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 reporting date, taking into account the risks and uncertainties surrounding the obligation and discount rates. 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 discounted at the market discount rate.

Over time the carrying value of the liability is increased for the changes in the present value based on the current market discount rates and liability risks. When some or all of the economic benefits required to settle a provision are expected to be recovered from a third party, the receivable is recognized as an asset if it is virtually certain that reimbursement will be received, and the amount receivable can be measured reliably.

Common shares are classified as equity. Incremental costs directly attributable to the issue of common shares are recognized as a deduction from equity. Common shares issued for consideration other than cash, are valued based on their market value at the date the shares are issued.

The Company has adopted a residual value method with respect to the measurement of shares and warrants issued as private placement units. The residual value method first allocates value to the more easily measurable component based on fair value and then the residual value, if any, to the less easily measurable component. The Company considers the fair value of common shares issued in the private placements to be the more easily measurable component and the common shares are valued at their fair value, as determined by the closing market price on the announcement date. The balance, if any, is allocated to the attached warrants. Any fair value attributed to the warrants is recorded as reserves.

The Company’s stock option plan allows Company employees, directors, officers and consultants to acquire shares of the Company. The fair value of options granted is recognized as share-based payments expense with a corresponding increase in equity reserves. The fair value of the options granted is measured using the Black-Scholes option pricing model, taking into account the terms and conditions upon which the options were granted. Fair value is measured at grant date, and each tranche is recognized using the graded vesting method over the period during which the options vest.

At each financial reporting date, the amount recognized as an expense is adjusted to reflect the actual number of stock options that are expected to vest. In situations where equity instruments are issued to

non-employees

and some or all of the goods or services received by the entity as consideration cannot be specifically identified, they are measured at the fair value of the share-based payment, otherwise share-based payment awards to

non-employees

are measured at the fair value of goods or services received. An individual is classified as an employee when the individual is an employee for legal or tax purposes (direct employee) or provides services similar to those performed by a direct employee.

Resource expenditure deductions for income tax purposes related to exploration activities funded by flow-through share arrangements are renounced to investors under Canadian income tax legislation. On issuance, the Company separates the flow-through share into i) a flow-through share premium, equal to the estimated premium, if any, investors pay for the flow-through feature, which is recognized as a liability and ii) share capital. Upon qualifying expenditures being incurred, the Company recognizes a deferred tax liability for the taxable temporary difference that arises from the difference between the carrying amount of eligible expenditures capitalized as exploration and evaluation assets and its tax base and the premium liability is reduced and recognized as a reduction of deferred tax expense. Proceeds received from the issuance of flow-through shares must be expended on Canadian resource property exploration within a period of two years. Failure to expend such funds as required under the Canadian income tax legislation will result in a Part XII.6 tax to the Company on flow-through proceeds renounced under the “Look-back” Rule. When applicable, this tax is classified as a financial expense.

The Company uses the treasury stock method to compute the dilutive effect of options, warrants and other similar instruments. Under this method, the weighted average number of shares outstanding used in the calculation of diluted loss per share assumes that the deemed proceeds received from the exercise of stock options, share purchase warrants and their equivalents would be used to repurchase common shares of the Company at the average market price during the period.

Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is not recognized for the following temporary differences: the initial recognition of assets or liabilities in a transaction that is not a business combination and that affects neither accounting nor taxable profit or loss, and differences relating to investments in subsidiaries and jointly controlled entities to the extent that it is probable that they will not reverse in the foreseeable future. In addition, deferred tax is not recognized for taxable temporary differences arising on the initial recognition of goodwill. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the laws that have been enacted or substantively enacted by the reporting date.

Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset current tax liabilities and assets, and they relate to income taxes levied by the same tax authority on the same taxable entity, or on different tax entities, but they intend to settle current tax liabilities and assets on a net basis or their tax assets and liabilities will be realized simultaneously.

A deferred tax asset is recognized for unused tax losses, tax credits and deductible temporary differences, to the extent that it is probable that future taxable profits will be available against which they can be utilized. Future taxable profits are determined based on the reversal of relevant taxable temporary differences. If the amount of taxable temporary differences is insufficient to recognize a deferred tax asset in full, then future taxable profits, adjusted for reversals of existing temporary differences, are considered, based on the business plan for the Company. Deferred tax assets are reviewed at each reporting date and are reduced to the extent that it is no longer probable that the related tax benefit will be realized.

The Company classifies its financial assets in the following categories: at fair value through profit and loss (“FVTPL”), at fair value through other comprehensive income (“FVTOCI”) or at amortized cost. The Company determines the classification of financial assets at initial recognition. The classification of debt instruments is driven by the Company’s business model for managing the financial assets and their contractual cash flow characteristics. Equity instruments that are held for trading (including all equity derivative instruments) are classified as at FVTPL. For other equity instruments, on the day of acquisition the Company can make an irrevocable election (on an

instrument-by-instrument

basis) to designate them as at FVTOCI. Financial liabilities are measured at amortized cost, unless they are required to be measured at FVTPL (such as instruments held for trading or derivatives) or the Company has opted to measure them at FVTPL (such as the Convertible Debentures).

As the Company has taken an exemption not to restate prior periods with respect to classification and measurement, it has recognized the cumulative effects of retrospective application to shareholders’ equity at the beginning of the 2018 annual reporting period that includes the date of initial application. Therefore, the adoption of IFRS 9 resulted in a decrease to opening accumulated deficit on January 1, 2018 of $503,146 with a corresponding adjustment to accumulated other comprehensive (loss) income, arising due to the changed classification on the accumulated fair value gain (loss) due to the change in the Company’s own credit risk as at January 1, 2018.

Elected investments in equity instruments at FVTOCI are initially recognized at fair value plus transaction costs. Subsequently they are measured at fair value, with gains and losses arising from changes in fair value recognized in other comprehensive (loss) income.

Financial assets and liabilities carried at FVTPL are initially recorded at fair value and transaction costs are expensed in the consolidated statements of net (loss) income. Realized and unrealized gains and losses arising from changes in the fair value of the financial assets and liabilities held at FVTPL are included in the consolidated statements of net (loss) income in the period in which they arise. Where management has opted to recognize a financial liability at FVTPL, any changes associated with the Company’s own credit risk will be recognized in other comprehensive (loss) income. The Company’s Convertible Debentures have been recognized at FVTPL.

The adoption of the expected credit loss impairment model under IFRS 9 had no impact on the carrying amounts of our financial assets on the transition date given the Company transacts exclusively with large international financial institutions and amounts receivable are comprised of value-added tax receivable from the government of Canada.

At each reporting date, the Company measures the loss allowance for the financial asset at an amount equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly since initial recognition. If at the reporting date, the financial asset has not increased significantly since initial recognition, the Company measures the loss allowance for the financial asset at an amount equal to twelve month expected credit losses.

The Company derecognizes financial assets only when the contractual rights to cash flows from the financial assets expire, or when it transfers the financial assets and substantially all the associated risks and rewards of ownership to another entity. Gains and losses on derecognition are generally recognized in the consolidated statements of net (loss) income. However, gains and losses on derecognition of financial assets classified as FVTOCI remain within the accumulated other comprehensive (loss) income.

The Company derecognizes financial liabilities only when its obligations under the financial liabilities are discharged, cancelled or expired. The difference between the carrying amount of the financial liability derecognized and the consideration paid and payable, including any

non-cash

assets transferred or liabilities assumed, is recognized in the consolidated statements of net (loss) income.

The Company has adopted all of the requirements of IFRS 16 Leases (“IFRS 16”), as of January 1, 2019, using the modified retrospective approach and therefore the comparative information has not been restated and continues to be reported under IAS 17 Leases (“IAS 17”). IFRS 16 specifies how to recognize, measure, present and disclose leases. IFRS 16 provides a single lessee accounting model, requiring lessees to recognize assets and liabilities for all major leases. The impact of the transition is shown in Note 4(n) below.

At inception of a contract, the Company assesses whether a contract is, or contains, a lease. A contract is, or contains, a lease if the contracts conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To assess whether a contract conveys the right to control the use of an identified asset, the Company assesses whether:

The Company recognizes a

right-of-use

asset and a lease liability at the lease commencement date. The

right-of-use

asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any initial direct costs incurred and an estimate of costs to dismantle and remove the underlying asset or to restore the underlying asset or the site on which it is located, less any lease incentives received.

The

right-of-use

asset is subsequently depreciated using the straight-line method from the commencement date to the earlier of the end of the useful life of the

right-of-use

asset or the end of the lease term. The estimated useful lives of the

right-of-use

assets are determined on the same basis as those of the property and equipment. In addition, the

right-of-use

asset is periodically reduced by impairment losses, if any, and adjusted for certain remeasurements of the lease liability.

The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily determined, the Company’s incremental borrow rate. Generally, the Company uses its incremental borrowing rate as the discount rate.

The lease liability is measured at amortized costs using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in index or rate, if there is a change in the Company’s estimate of the amount expected to be payable under a residual value guarantee, or if the Company changes its assessment of whether it will exercise a purchase, extension or termination option.

When the lease liability is remeasured in this way, a corresponding adjustment is made to the carrying amount of the

right-of-use

asset, or is recorded in profit or loss in the carrying amount of the

right-of-use

asset has been reduced to zero.

The Company has elected to apply the recognition exemption not to recognize

right-of-use

assets and lease liabilities for short-term leases that have a lease term of 12 months or less and leases of

low-value

assets. The lease payments associated with these leases is recognized as an expense on a straight-line basis over the lease term.

On initial application, the Company has elected to record

right-of-use

assets based on the corresponding lease liability.

Right-of-use

assets and lease obligations of $2,826,512 and $3,222,380, respectively, were recorded as of January 1, 2019, with no net impact on retained earnings. When measuring lease liabilities, the Company discounted lease payments using an incremental borrowing rate at January 1, 2019. The weighted-average rate applied is 7.40%.

The transition to IFRS 16 from IAS 17 is shown in the reconciliation table below, starting with the lease commitments below as at December 31, 2018 and adjusting for the operating expenses included in the lease commitments and the discounted portion of the lease commitment to equal the Lease liability as at January 1, 2019.
