(b) Foreign currency translation

Transactions in foreign currencies are initially recorded at the functional currency rate of exchange at the date of the transaction.

Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency rate of exchange at the date of the statement of financial position. Foreign exchange gains (losses) are recorded in the consolidated statement of operations and comprehensive income (loss) for the year.

Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rates as at the dates of the initial transactions. Non-monetary items measured at fair value in a foreign currency are translated using the exchange rates at the date when the fair value is determined.

(c) Cash and cash equivalents

Cash and cash equivalents consist of cash on hand and short-term investments with original maturity dates of less than ninety days or that are fully redeemable without penalty or loss of interest.

(d) Inventories

Gold on hand, gold in process and stockpiled ore inventories are recorded at the lower of weighted average production cost and net realizable value. Production costs include the cost of raw materials, direct labour, mine-site overhead expenses and applicable depreciation and depletion. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and long-term metal prices less estimated future costs to convert the inventories from their respective states into saleable form less estimated costs to sell.

Production costs are included in work-in-process inventory based on current costs incurred up to the point of dore production. The costs of finished goods represent the costs of work-in-process inventories plus applicable treatment costs. The costs of inventories sold during the period are presented as production costs in the statement of operations and comprehensive income (loss) for the period.

Additions to the cost of ore stockpiles are based on the related current cost of production for the period, while reductions in the cost of ore stockpiles are based on the weighted-average cost per tonne of ore in the stockpile. Stockpiles are segregated between current and non-current inventories in the consolidated statement of financial position based on the planned period of usage.

Supplies and spare parts are valued at the lower of weighted-average cost and net realizable value. Replacement costs of materials and spare parts are generally used as the best estimate of net realizable value. Provisions are recorded to reduce the carrying amount of materials and spare parts inventory to net realizable value to reflect current intentions for the use of redundant or slow-moving items. Provisions for redundant and slow-moving items are made by reference to specific items of inventory. The Company reverses write-downs where there is a subsequent increase in net realizable value and where the inventory is still on hand.

(e) Mineral properties, plant and equipment ("MPP&E")

(i) Mineral properties

Recognition

Capitalized costs of mining properties include the following:

- costs assigned to mining properties acquired in business combinations;

- expenditures incurred to develop mineral properties including pre-production stripping costs;

- stripping costs in the production phase of a mine if certain criteria have been met (see below);

- costs to define and delineate known economic resources and develop the project;

- borrowing costs attributable to qualifying mining properties; and

- estimates of reclamation and closure costs.

Stripping costs

In open pit mining operations, it is necessary to incur costs to remove overburden and other mine waste materials in order to access the ore from which minerals can be extracted economically. Stripping costs incurred in order to provide initial access to the ore body (referred to as pre-production stripping) are capitalized as incurred. Stripping costs incurred during the production stage of an open pit mine are accounted for as production costs in the consolidated statement of operations and comprehensive income during the period that the stripping costs were incurred, unless these costs provide a future economic benefit. Production phase stripping costs are considered to generate a future economic benefit when (i) it is probable that future economic benefit associated with the stripping activity will flow to the entity; (ii) the entity can identify the component of the ore body for which access has been improved; and (iii) the costs relating to the stripping activity associated with that component can be measured reliably. These costs are capitalized as mineral properties, plant and equipment.

Production costs are allocated between inventory produced and the stripping asset based on the volume of waste extracted compared with the expected volume, for a given volume of ore production. Stripping costs incurred and capitalized during the production phase are depleted using the units-of-production method over the proven and probable reserves (ore tonnes) of the component of the ore body to which access has been improved as a result of the specific stripping activity.

Management reviews the estimates of the waste and ore in each identified component of operating open pit mines at the end of each financial year, and when events and circumstances indicate that such a review should be made. Deferred stripping assets are written-down to their recoverable amount when their carrying value is not considered supportable. Changes to the estimated identification of components and the associated waste and ore within each component are accounted for prospectively.

Exploration and evaluation expenditures

Exploration and evaluation expenditures include the costs of acquiring rights to explore, exploratory drilling and related exploration costs incurred on sites without an existing mine and on areas outside the boundary of a known mineral deposit which contain proven and probable reserves. Exploration and evaluation expenditures incurred on a mineral deposit, with the exception of acquisition costs and costs arising from the recognition of an asset retirement provision, are expensed as incurred up to the date of establishing that costs incurred on a mineral deposit are technically feasible and commercially viable.

Expenditures incurred on a mineral deposit subsequent to the establishment of its technical feasibility and commercial viability are capitalized and included in the carrying amount of the related mining property.

The technical feasibility and commercial viability of a mineral deposit is assessed based on a combination of factors, such as, but not limited to:

- the extent to which mineral reserves or mineral resources have been identified through a feasibility study or similar level document;

- the results of optimization studies and further technical evaluation carried out to mitigate project risks identified in the feasibility study;

- the status of environmental permits, and

- the status of mining leases or permits.

Borrowing costs

Borrowing costs directly relating to the financing of qualifying assets are added to the capitalized cost of those related assets until such time as the assets are substantially ready for their intended use or sale which, in the case of mining properties, is when they are capable of commercial production. Where funds have been borrowed specifically to finance a project, the amount capitalized represents the actual borrowing costs incurred. Where the funds used to finance a project form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to relevant general borrowings of the Company during the period. Capitalized borrowing costs are depreciated over the life of the related asset.

All other borrowing costs are recognized in the consolidated statement of operations and comprehensive income in the year in which they are incurred. Borrowing costs are included as part of interest paid in the statement of cash flows.

Depletion

Mineral properties in production are depleted on a mine-by-mine basis using the units-of-production method over the mine's estimated proven and probable reserves, with the exception of deferred stripping which is depleted using the unit-of-production method over the reserves that directly benefit from the specific stripping activity and will commence when the mine is capable of operating in the manner intended by management. In the event proven and probable reserves are not identified management will use their best estimate from internally generated information.

The Company uses a number of criteria to assess whether the mine is in the condition necessary for it to be capable of operating in a manner intended by management. These criteria include, but are not limited to:

- completion of operational commissioning of each major mine and plant component;

- demonstrated ability to mine and mill consistently and without significant interruption at a pre-determined average rate of designed capacity;

- the passage of a reasonable period of time for testing of all major mine and plant components;

- gold recoveries at or near expected production levels; and

- a significant portion of available funding is directed towards operating activities.

Mineral properties in development are not depleted.

(ii) Plant and equipment

Recognition

The cost of plant and equipment consists of the purchase price, costs directly attributable to the delivery of the asset to the location and the condition necessary for it to be capable of operating in the manner intended by management, including the cost of testing whether these assets are operating in the manner intended by management. Subsequent costs are included in the asset's carrying amount or recognized as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Company and the cost can be measured reliably. Where significant components of an asset have differing useful lives, depreciation is calculated on each separate component.

Depreciation

Depreciation of an asset begins when it is available for use, i.e. when it is in the location and condition necessary for it to be capable of operating in the manner intended by management.

The carrying amounts of plant and equipment are depreciated using either the straight-line or units-of-production method over the shorter of the estimated useful life of the asset or the life of mine. The significant classes of depreciable plant and equipment and their estimated useful lives are as follows:

Asset Class	Estimated Useful Life
Fixed plant & related components and infrastructure	Units of production over life of mine
Mobile and other mine equipment components	3 to 12 years
Computer equipment and software	3 years
Right-of-use assets	Straight-line over lease term

Management reviews the estimated useful lives, residual values and depreciation methods of the Company's plant and equipment at the end of each financial year, and when events and circumstances indicate that such a review should be made. Changes to estimated useful lives, residual values or depreciation methods resulting from such review are accounted for prospectively.

Major maintenance and repairs

Expenditure on major maintenance and repairs includes the cost of replacement parts of assets and overhaul costs. Where an asset or part of an asset is replaced and it is probable that future economic benefits associated with the item will be available to the Company, that expenditure is capitalized and the carrying amount of the item replaced derecognized. Similarly, overhaul costs associated with major maintenance are capitalized when it is probable that future economic benefits will be available and any remaining carrying amounts of the cost of previous overhauls are derecognized. All other maintenance and repair costs are expensed as incurred.

(iii) Impairment of non-financial assets

The carrying amounts of assets included in mineral properties, plant and equipment are reviewed for impairment when events and changes in circumstances indicate that the related carrying amounts may not be recoverable. If any such indication exists, the recoverable amount of the relevant cash-generating unit ("CGU") is estimated in order to determine the extent of impairment. 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.

The carrying amounts of the CGUs are compared to their recoverable amounts where the recoverable amount is the higher of value-in-use ("VIU") and fair value less costs to sell ("FVLCS"). FVLCS is defined as the amount that would be obtained from the sale of the asset in an orderly transaction between market participants at the measurement date. 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. The fair value of mine sites 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. If a reliable estimate of future cash flows cannot be made, then fair value is determined by reference to market prices for comparable assets. If the recoverable amount of an asset (or CGU) is estimated to be less than its carrying amount, the carrying amount is reduced to its recoverable amount. An impairment is recognized immediately in the consolidated statement of operations and comprehensive income.

Mineral properties, plant and equipment that have been impaired are tested for possible reversal of the impairment whenever events or changes in circumstances indicate that the impairment may have reversed. When an impairment loss reverses in a subsequent period, the revised carrying amount shall not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset previously, less subsequent depletion and depreciation. Reversals of impairment losses are recognized in the consolidated statements of operations in the period in which the reversals occur.

(iv) Derecognition

Upon disposal or abandonment, the carrying amounts of mineral properties and plant and equipment are derecognized and any associated gains or losses are recognized in the consolidated statement of operations and comprehensive income.

(f) Leases

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 contract 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 it has the right to obtain substantially all of the economic benefits from and to direct the use of the identified asset.

At commencement or on modification of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component on the basis of its relative stand-alone prices.

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 end of the lease term, unless the lease transfers ownership of the underlying asset to the Company by the end of the lease term or the cost of the right-of-use asset reflects that the Company will exercise a purchase option. In that case, the right-of-use asset will be depreciated over the useful life of the underlying asset, which is determined on the same basis as those of 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 borrowing rate. Generally, the Company uses its incremental borrowing rate as the discount rate. The Company determines its incremental borrowing rate by obtaining interest rates from various external financing sources and makes certain adjustments to reflect the terms of the lease and type of the asset leased.

Lease payments included in the measurement of the lease liability comprise the following:

	•	fixed payments, including in-substance fixed payments;
	•	variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;
	•	amounts expected to be payable under a residual value guarantee; and
	•	the exercise price under a purchase option that the Company is reasonably certain to exercise, lease payments in an optional renewal period if the Company is reasonably certain to exercise an extension option, and penalties for early termination of a lease unless the Company is reasonably certain not to terminate early.

The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an 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, if the Company changes its assessment of whether it will exercise a purchase, extension or termination option, or if there is a revised in-substance fixed lease payment. 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 the consolidated statement of operations and comprehensive income if the carrying amount of the right-of-use asset has been reduced to zero.

Short-term leases and leases of low-value assets

The Company has elected not to recognize right-of-use assets and lease liabilities for leases of low-value assets and short-term leases, including office equipment. The Company recognizes the lease payments associated with these leases as an expense on a straight-line basis over the lease term.

(g) Provisions

General

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. Where the Company expects some or all of a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognized as a separate asset, but only when the reimbursement is virtually certain. The expense relating to any provision is presented in the consolidated statement of operations and comprehensive income net of any reimbursement. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects where appropriate, the risks specific to the liability. Where discounting is used, the increase in the provision due to the passage of time is recognized as finance expense in the consolidated statement of operations and comprehensive income.

Asset retirement provisions

An obligation to incur restoration, rehabilitation and environmental costs arises when environmental disturbance is caused by the exploration, development or ongoing production of a mineral property interest. The Company records the estimated present value of future cash flows associated with site reclamation as a liability when the liability is incurred with a corresponding increase in the carrying value of the related assets. Discount rates using a pre-tax, risk-free rate that reflect the time value of money are used to calculate the net present value. The liability is accreted over time to reflect the unwinding of the discount with the accretion expense included in finance costs in the consolidated statement of operations and comprehensive income (loss). Changes in estimates or circumstances include changes in legal or regulatory requirements, increased obligations arising from additional mining and exploration activities, changes to cost estimates, changes to the discount rate and changes to the risk-free interest rates.

(j) Financial instruments

(i) Financial assets

Recognition and measurement

The Company recognizes a financial asset in its statement of financial position when the Company becomes party to the contractual provisions of the instrument. All financial assets are initially recorded at fair value plus directly attributable transaction costs and classified as either (i) financial assets subsequently measured at amortized cost, (ii) financial assets subsequently measured at fair value through other comprehensive income or (iii) financial assets subsequently measured at fair value through profit or loss. The basis of classification takes into consideration both the Company's business model for managing and the contractual cash flow characteristics of the financial assets.

A financial asset is measured at amortized cost if the financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows and the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

A financial asset is measured at fair value through other comprehensive income if the financial asset is held within a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets and the contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

A financial asset is measured at fair value through profit or loss unless it is measured at amortised cost or at fair value through other comprehensive income. Fair value changes in financial assets classified as fair value through profit or loss, if any, are recognized in the consolidated statement of operations and comprehensive income.

Derecognition

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is derecognized when:

- the contractual rights to receive cash flows from the asset have expired, or

- the Company has transferred its contractual rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a 'pass-through 'arrangement; and either (a) the Company has transferred substantially all the risks and rewards of ownership of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

(ii) Financial liabilities

Recognition and measurement

All financial liabilities are initially recorded at fair value less transaction costs. All financial liabilities are subsequently measured at amortized cost using the effective interest method, except for:

- financial liabilities at fair value through profit or loss;

- financial liabilities that arise when a transfer of a financial asset does not qualify for derecognition or when the continuing involvement approach applies;

- financial guarantee contracts;

- commitments to provide a loan at a below-market interest rate; and

- contingent consideration recognized by an acquirer in a business combination to which IFRS 3, Business combinations, applies.

An entity may, at initial recognition, irrevocably designate a financial liability as measured at fair value through profit or loss when a contract contains one or more embedded derivatives, or when doing so results in more relevant information, because either (a) it eliminates or significantly reduces a measurement or recognition inconsistency (i.e. an accounting mismatch); or (b) a group of financial liabilities or financial assets and financial liabilities is managed and its performance is evaluated on a fair value basis.

Fair value changes of financial liabilities classified as fair value through profit or loss, if any, are recognized in the consolidated statement of operations and comprehensive income.

(k) Share-based compensation

The Company has a share option plan and share unit plan which are described in note 11. For share options, the fair value of share-based compensation awards is determined at the date of grant using the Black-Scholes option pricing model. The Company records all share-based compensation for options using the fair value method with graded vesting. Under the fair value method, share-based payments are measured at the fair value of the consideration received or the fair value of the equity instruments issued or liabilities incurred, whichever is more reliably measurable, and are charged over the vesting period to the consolidated statement of operations and comprehensive income. The offset is credited to Equity reserves ratably over the vesting period, after adjusting for the number of awards that are expected to vest.

Expenses recognized for forfeited awards are reversed. For awards that are cancelled, any expense not yet recognized is recognized immediately in the statement of operations and comprehensive income.

Where the terms of an equity-settled award are modified, as a minimum an expense is recognized as if the terms had not been modified over the original vesting period. In addition, an expense is recognized for any modification which increases the total fair value of the share-based payment arrangement as measured at the date of modification, over the remainder of the vesting period.

For cash-settled share-based payments (note 11), the Company measures the goods or services acquired and the liability incurred at the fair value of the liability. The corresponding share-based compensation expense is recognized over the vesting period of the award. As these awards will be settled in cash, the liability is remeasured at fair value at each reporting period and at the date of settlement, with changes in fair value recognized in the consolidated statement of operations and comprehensive income in the period incurred.

(l) Income taxes

Income tax on the profit or loss for the periods presented comprises current and deferred income tax. Income tax is recognized in the consolidated statement of operations and comprehensive income except to the extent that it relates to items recognized directly in equity, in which case it is recognized in equity.

Current income tax expense is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at period end, adjusted for amendments to tax payable with regards to previous years.

Deferred income tax is recognized in respect of unused tax losses, tax credits and temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when they reverse, based on the tax rates that have been substantively enacted at the reporting date.

A deferred income tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. To the extent that the Company does not consider it probable that a future income tax asset will be recovered, it does not recognize the asset.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to set off current tax assets against current tax liabilities and when they relate to income taxes levied by the same taxation authority and the Company intends to settle its tax assets and liabilities on a net basis.

The Company records foreign exchange gains and losses representing the impacts of movements in foreign exchange rates on the tax bases of non-monetary assets and liabilities which are denominated in foreign currencies. Foreign exchange gains and losses relating to the translation of the deferred income tax balance from local statutory accounts to functional currency accounts are included in deferred income tax expense or recovery in the consolidated statement of operations and comprehensive income.
