Nature Of Operations [Abstract]
NATURE OF OPERATIONS	1. NATURE OF OPERATIONS Metalla Royalty & Streaming Ltd. (" Metalla Company TSX-V MTA NYSE MTA The Company has incurred a cumulative deficit to date of $38,676,639 as at May 31, 2020 (2019 - $31,285,237) and has had losses from operations for multiple years. Continued operations of the Company are dependent on the Company's ability to generate profitable earnings in the future, receive continued financial support, and/or complete external financing. Management expects that its cash balance, cash flows from operating activities, and available credit facilities will be sufficient to fund the operations of the Company for the next twelve months. In December 2019, the Company completed a consolidation of its common shares on the basis of one new share for four old shares (1:4) effective December 17, 2019 and the listing of its common shares on the NYSE effective January 8, 2020. All figures have been adjusted to reflect the one for four share consolidation.

Disclosure Of Significant Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Statement of Compliance The consolidated financial statements have been prepared using accounting policies in compliance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) and interpretations of the International Financial Reporting Interpretations Committee (“IFRIC”). Basis of preparation and measurement These consolidated financial statements have been prepared on a historical cost basis, except for financial instruments, which have been measured at fair value. In addition, these consolidated financial statements have been prepared using the accrual basis of accounting except for cash flow information. These consolidated financial statements are presented in Canadian Dollars except as otherwise indicated. Accounting standards adopted during the year Adoption of IFRS 16 Leases The Company adopted IFRS 16 Leases (" IFRS 16 At the inception of a contract, the new leasing standard requires the lessee to assess whether a contract is, or contains, a lease. A contract is, or contains, a lease if the lessee has the right to obtain substantially all of the economic benefits during the term of the arrangement and has the right to direct the use of the asset. If a lease is identified, the new standard eliminates the classification of leases as either operating or finance leases, and all leases that have a term of at least 12 months and are not of a low value will be recorded on the Company's consolidated statement of financial position. The Company has completed its assessment of the new standard. The process included a review of all lease and service contracts, to determine if we have the right to control the use of an identified asset for a period of time in exchange for consideration. Based on the Company's analysis, the only contract to which the Company will apply the new standard relates to the lease for the use of the Company's office premise. As a result of adopting the new standard, the Company recognized a right-of-use asset of $26,029. The right-of-use asset was measured at an amount equal to the lease liability on adoption. New accounting policy for leases under IFRS 16 Leases At inception of a contract, an assessment is made as to 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. At the commencement date of a lease, a right-of-use asset and a lease liability are recognized. The right-of-use asset is initially measured at cost, which is comprised of the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, less any lease incentives received. A lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by the interest rate implicit in the lease, or if that rate cannot be readily determined, the incremental borrowing rate. The lease obligation is measured at amortized cost using the effective interest method and remeasured if there is a change in future lease payments. The right-of-use asset is subsequently depreciated from the commencement date to the earlier of the end of the lease term, or the end of the useful life of the asset. An assessment is made at the end of each reporting period if there is an indication the carrying value of the right-of-use asset is not recoverable. Adoption of IFRIC 23 Uncertainty over Income Tax Treatments The Company adopted IFRIC 23 Uncertainty over Income Tax Treatments (" IFRIC 23 Principles of consolidation These consolidated financial statements include the accounts of the parent company and its subsidiaries after eliminating intercompany balances and transactions. Subsidiaries Subsidiaries are all entities over which the Company has exposure to variable returns from its involvement and has the ability to use power over the investee to affect its returns. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Company controls another entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company until the date on which control ceases. Foreign currency translation These consolidated financial statements are expressed in Canadian dollars, unless otherwise noted. The functional currency of the Company is the Canadian dollar, which is the currency of the primary economic environment in which the entity operates. The Company's subsidiaries have functional currencies of either the Canadian dollar or the United States ("US") dollar depending on the currency of the primary environment where the entity operates. Determination of functional currency may involve certain judgements to determine the primary economic environment. Transactions in currencies other than the functional currency are recorded at exchange rates prevailing on the dates of the transactions. At the end of each reporting period, the monetary assets and liabilities of the Company that are denominated in foreign currencies are translated at the rate of exchange at the reporting date while non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at the exchange rates approximating those in effect on the date of the transactions. Exchange gains and losses arising on translation are included in the consolidated statement of loss and comprehensive loss. On translation of the entity whose functional currency is the US dollar, revenues and expenses are translated at the exchange rates approximating those in effect on the date of the transactions. Assets and liabilities are translated at the rate of exchange at the reporting date. Exchange gains and losses, including results of re-translation, are recorded in the foreign currency translation adjustment. Royalty, stream, and other interests Royalty, stream, and other interests consist of acquired royalty, stream, and other interests. These interests are recorded at cost and capitalized as tangible assets with finite lives. They are subsequently measured at cost less accumulated depletion and accumulated impairment losses, if any. Project evaluation costs that are not related to a specific royalty or stream asset are expensed in the period incurred. Producing royalty and stream interests are depleted using the units-of-production method over the life of the property to which the interest relates, which is estimated using available information of proven and probable reserves and the portion of resources expected to be classified as mineral reserves at the mine corresponding to the specific agreement. On acquisition of a royalty or stream interest, an allocation of its fair value may be attributed to the exploration potential of the interest and is recorded as an exploration asset on the acquisition date. The carrying value of the exploration potential is accounted for in accordance with IFRS 6 Exploration and Evaluation of Mineral Resources (“IFRS 6”) and is not depleted until such time as the technical feasibility and commercial viability have been established, at which point the value of the asset is accounted for in accordance with IAS 16 Property, Plant and Equipment (“IAS 16”). Upon demonstration of the technical and commercial feasibility of a project and a development decision, the carrying value related to that project is subject to an impairment test and is reclassified in accordance with IAS 16. Joint operations Under IFRS 11 Joint Arrangements investments in joint arrangements are classified as either joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. The Company recognizes its direct right to the assets, liabilities, revenues, and expenses of joint operations and its share of any jointly held or incurred assets, liabilities, revenues, and expenses. Investments in associates Companies over which the Company has significant influence, but not control, are determined to be associates and accounted for using the equity basis of accounting, whereby the investment is initially recorded at cost, adjusted to recognize the Company's share of earnings or losses and reduced by dividends received. The Company assesses its equity investments for impairment if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the equity investment and if the event or events have an impact on the estimated future cash flow of the investment. Objective evidence of impairment of an equity investment includes: • Significant financial difficulty of the associated companies; • Becoming probable that the associated companies will enter bankruptcy or other financial reorganization; or • National or local economic conditions that correlate with defaults of the associated companies. Impairment of royalty, stream, and other interests The carrying amounts of non-financial assets, excluding deferred income tax assets, are reviewed for impairment at each reporting date, or whenever events or changes in circumstances indicate the carrying amounts may not be recoverable. If there are indicators of impairment, a review is undertaken to determine whether the carrying amounts are in excess of their recoverable amounts. Reviews are undertaken on an asset-by-asset basis, except where the recoverable amount for an individual asset cannot be determined, in which case the review is undertaken at the cash-generating unit (“CGU”) level. If the carrying amount of a CGU or non-financial asset exceeds the recoverable amount, being the higher of its fair value less costs to sell and its value-in-use, an impairment loss is recognized in net loss as the excess of the carrying amount over the recoverable amount. With respect to CGUs, impairment loses are allocated to reduce the carrying amounts of the assets of the CGU on a pro-rata basis. The future cash flow expected is derived using estimates of proven and probable reserves, a portion of resources that is expected to be converted into reserves and information regarding the Company's royalty, stream, and other production-based interests, respectively, that could affect the future recoverability of the Company's interests. Discount factors are determined individually for each asset and reflect their respective risk profiles. In certain circumstances, the Company may use a market approach in determining the recoverable amount which may include an estimate of (a) net present value of estimated future cash flows; (b) dollar value per ounce or pound of reserve/resource; (c) cash-flow multiples; and/or (d) market capitalization of comparable assets. Non-financial assets that have previously been impaired are tested for a possible reversal of the impairment whenever events or changes in circumstances indicate that the impairment may have reversed, or may have partially reversed. In these instances, the impairment loss is reversed to the recoverable amount but not beyond the carrying amount, net of amortization, that would have arisen if the prior impairment loss had not been recognized. Revenue recognition Revenue is comprised of revenue earned in the year from royalty, stream, and other interests. The Company recognizes revenue upon the transfer of control of the relevant commodity to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those commodities. For stream interests, revenue recognition occurs when the relevant commodity received from the stream operator is delivered by the Company to its third-party customers. Revenue is measured at the fair value of the consideration received or receivable when management can reliably estimate the amount, pursuant to the terms of the sales contract. For royalty interests, revenue recognition occurs when control of the relevant commodity is transferred to the end customer by the operator of the royalty property. Revenue is measured at the fair value of the consideration received or receivable when management can reliably estimate the amount, pursuant to the terms of the royalty agreement. In some instances, the Company will not have access to sufficient information to make a reasonable estimate of consideration to which it expects to be entitled and, accordingly, revenue recognition is deferred until management can make a reasonable estimate. Differences between estimates and actual amounts are adjusted and recorded in the period that the actual amounts are known. Financial instruments All financial instruments are initially recorded at fair value and designated as follows: Cash includes cash on account and is subsequently measured at amortized cost. Trade receivables relate to amounts received from sales of refined gold and silver and royalty revenue. These receivables are non-interest bearing and are recognized at fair value and are subsequently measured at amortized cost. We have applied the simplified approach to determining expected credit losses, which requires expected lifetime losses to be recognized upon initial recognition of the receivables. Marketable securities are designated as fair value through profit and loss (" FVTPL FVOCI Accounts payables, accrued liabilities, and loans payable are initially recorded at fair value, less transaction costs. These financial liabilities are subsequently measured at amortized cost, calculated using the effective interest rate method Related party transactions Parties are considered related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered related if they are subject to common control or significant influence. A transaction is considered a related party transaction when there is a transfer of resources or obligations between related parties. Share capital Common shares issued for non-monetary consideration are recorded at their fair value based on closing price on the measurement date and classified as equity. The measurement date is defined as the earliest of the date at which the commitment for performance by the counterparty to earn the common shares is reached or the date at which the counterparty's performance is complete. The proceeds from the issue of units are allocated between common shares and share purchase warrants on a pro-rata basis based on the relative fair values. The fair value of the common shares is based on the market closing price on the date of issuance and the fair value of the share purchase warrants is determined using the Black-Scholes option pricing model. Transaction costs directly attributable to the issue of common shares are recognized as a deduction from equity, net of any tax effects. Earnings (loss) per share The Company presents basic earnings (loss) per share data for its common shares, calculated by dividing the income (loss) attributable to equity holders of the Company by the weighted average number of common shares issued and outstanding during the period. Diluted earnings per share is calculated by adjusting the earnings attributable to equity holders and the weighted average number of common shares outstanding for the effects of all potentially dilutive common shares. The calculation of diluted earnings per share assumes that the proceeds to be received on the exercise of dilutive share options and warrants are used to repurchase common shares at the average market price during the period. In periods where a loss is reported, diluted loss per share is the same as basic loss per share as the effects of potentially dilutive common shares would be anti-dilutive. Income taxes Income tax expense consists of current and deferred tax expense. Income tax expense is recognized in the consolidated statement of loss and comprehensive loss. Current tax expense is the expected tax payable on the taxable income for the period, using tax rates enacted or substantively enacted at period end, adjusted for amendments to tax payable with regards to previous periods. Deferred tax assets and liabilities are recognized for deferred tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and losses carried forward. 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 income in the period that 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. To the extent that the Company does not consider it probable that a deferred tax asset will be recovered, the deferred tax asset is reduced. Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset 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 current tax assets and liabilities on a net basis. Share-based payments The Company grants stock options and restricted share units (" RSUs The fair value method of accounting is used for share-based payment transactions. Under this method, the cost of stock options and other equity-settled share-based payment arrangements are recorded based on the estimated fair value at the grant date and charged to earnings over the vesting period. Where awards are forfeited because non-market based vesting conditions are not satisfied, the expense previously recognized is proportionately reversed in the period the forfeiture occurs. Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segment, has been identified as the Chief Executive Officer ("CEO"). The Company operates in a single segment, the acquisition and management of precious metal royalties, streams, and similar production-based interests. In addition, the Company has corporate activities, which include the evaluation and acquisition of new precious metal royalties, streams, and similar production-based interests, treasury and finance, regulatory reporting, and corporate administration. Critical accounting estimates and judgments The preparation of the Company’s consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Estimates and assumptions are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes can differ from these estimates. Information about significant areas of estimation uncertainty and judgments made by management in preparing the consolidated financial statements are described below. The preparation of consolidated financial statements in conformance with IFRS requires management to make estimates, judgments and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue, and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Critical accounting estimates are estimates and assumptions made by management that may result in a material adjustment to the carrying amount of assets and liabilities within the next financial year and include, but are not limited to, the following: a) Royalty interests The Company holds royalty interests in production stage mineral properties. The royalty interests are recorded initially at their costs and are being depleted using the units of production basis over the expected life of the related mineral property, which is determined using available estimates of future metal prices and future production. Proven and probable reserves and future production plans associated with the royalty interests as determined by the operators impact the measurement of the respective assets. These estimates affect the depletion of the royalty interests and the assessment of the recoverability of the carrying value of the royalty interests. Management considers both external and internal sources of information in assessing whether there are any indications that the Company’s royalty interests are impaired. External sources of information management considers include changes in the market, economic and legal environment in which the Company operates that are not within its control and affect the recoverable amount of its royalty interests. Internal sources of information that management considers include the indications of economic performance of the assets. In determining the recoverable amounts of the Company’s royalty interests, management makes estimates of the discounted net cash flows expected to be derived from the Company’s royalty interests, costs of disposal, and the appropriate discount rates and discount multiples that apply to the specific asset. Reductions in metal price forecasts, increases in estimated future costs of production for the mine operators, reductions in the amount of recoverable mineral reserves, mineral resources, and exploration potential, and/or adverse current economics can result in a write-down of the carrying amounts of the Company’s royalty interests. b) Estimation of depletion The Company’s royalty, stream, and other production-based interests that generate economic benefits are considered depletable and are depleted on a unit-of-production basis over the ounces of production that are expected to generate the cash flows that will be attributable to the Company. These calculations require the use of estimates and assumptions, including the amount of contained metals, the recovery rates, and payable rates for the contained metals being treated through a milling or refining process. Changes to these assumptions may impact the estimated recoverable reserves, resources or exploration potential which could directly impact the depletion rates used. Changes to depletion rates are accounted for prospectively. c) Income taxes The interpretation of existing tax laws or regulations in Canada, Australia, Argentina, the United States, or any of the countries in which our property interests are located requires the use of judgment. Differing interpretation of these laws or regulations could result in an increase in the Company's taxes, or other governmental charges, duties or impositions. In addition, the recoverability of deferred income tax assets, including expected periods of reversal of temporary differences and expectations of future taxable income, are assessed by management at the end of each reporting period and adjusted, as necessary, on a prospective basis.

Disclosure of detailed information about financial instruments [Abstract]
FINANCIAL INSTRUMENTS	13. FINANCIAL INSTRUMENTS The Company classified its financial instruments as follows: May 31 May 31 2020 2019 Financial assets Amortized cost: Cash $ 4,695,653 $ 4,603,062 Other receivables 51,099 — Fair value through profit or loss: Royalty and stream receivables — 129,960 Marketable securities 36,000 — $ 4,782,752 $ 4,733,022 Financial liabilities Amortized cost: Accounts payable and accrued liabilities $ 1,635,627 $ 1,126,982 Loans payable 4,595,440 2,798,975 $ 6,231,067 $ 3,925,957 Fair value Financial instruments recorded at fair value on the consolidated statement of financial position are classified using a fair value hierarchy that reflects the significance of the inputs used in making the measurements. The fair value hierarchy has the following levels: a) b) c) The fair value hierarchy requires the use of observable market inputs whenever such inputs exist. A financial instrument is classified to the lowest level of the hierarchy for which a significant input has been considered in measuring fair value. As at May 31, 2020, the Company did not have any financial instruments measured at fair value. The carrying value of cash, receivables, and accounts payable and accrued liabilities approximated their fair value because of the short-term nature of these instruments. Marketable securities are classified within Level 1 of the fair value hierarchy. Royalty, stream receivable (if any) includes provisional pricing, and final price and assay adjustments and is valued using observable market commodity forward prices and thereby classified within Level 2 of the fair value hierarchy. The fair value of the Company's loans payable is approximated by its carrying value as its interest rates are comparable to market interest rates. Capital risk management The Company's objectives when managing capital are to provide shareholder returns through maximization of the profitable growth of the business and to maintain a degree of financial flexibility relevant to the underlying operating and metal price risks while safeguarding the Company's ability to continue as a going concern. The capital of the Company consists of share capital. The Board of Directors does not establish a quantitative return on capital criteria for management. The Company manages the capital structure and makes adjustments to it in light of changes in economic conditions and the risk characteristics of the underlying assets. The Company may issue new shares in order to meet its financial obligations. The management of the Company believes that the capital resources of the Company as at May 31, 2020 are sufficient for its present needs for at least the next twelve months. The Company is not subject to externally imposed capital requirements. Credit risk Credit risk arises from cash deposits, as well as credit exposures to counterparties of outstanding receivables and committed transactions. There is no significant concentration of credit risk other than cash deposits. The Company's cash deposits are primarily held with a Canadian chartered bank. Receivables include value added tax due from the Canadian government. The carrying amount of financial assets recorded in the financial statements represents the Company's maximum exposure to credit risk. The Company believes it is not exposed to significant credit risk and overall, the Company's credit risk has not declined from the prior year. Liquidity risk The Company strives to maintain sufficient liquidity to meet its short-term business requirements, taking into account its anticipated cash flows from royalty interests, its holdings of cash, and its committed liabilities. The maturities of the Company's non‐current liability are disclosed in Note 7. All current liabilities are settled within one year. Currency risk The Company is exposed to the financial risk related to the fluctuation of foreign exchange rates. The Company primarily operates in Canada, Australia, Argentina, and the United States and incurs expenditures in currencies other than Canadian dollars. Thereby, the Company is exposed to foreign exchange risk arising from currency exposure. The Company has not hedged its exposure to currency fluctuations. Based on the above net exposure, as at May 31, 2020, and assuming that all other variables remain constant, a 1% depreciation or appreciation of the Canadian dollar against the US dollar would result in an increase/decrease of approximately $12,000 in the Company's pre-tax income or loss.

Disclosure Of Significant Accounting Policies [Abstract]
Basis of preparation and measurement	Basis of preparation and measurement These consolidated financial statements have been prepared on a historical cost basis, except for financial instruments, which have been measured at fair value. In addition, these consolidated financial statements have been prepared using the accrual basis of accounting except for cash flow information. These consolidated financial statements are presented in Canadian Dollars except as otherwise indicated.
Accounting standards adopted during the year	Accounting standards adopted during the year Adoption of IFRS 16 Leases The Company adopted IFRS 16 Leases (" IFRS 16 At the inception of a contract, the new leasing standard requires the lessee to assess whether a contract is, or contains, a lease. A contract is, or contains, a lease if the lessee has the right to obtain substantially all of the economic benefits during the term of the arrangement and has the right to direct the use of the asset. If a lease is identified, the new standard eliminates the classification of leases as either operating or finance leases, and all leases that have a term of at least 12 months and are not of a low value will be recorded on the Company's consolidated statement of financial position. The Company has completed its assessment of the new standard. The process included a review of all lease and service contracts, to determine if we have the right to control the use of an identified asset for a period of time in exchange for consideration. Based on the Company's analysis, the only contract to which the Company will apply the new standard relates to the lease for the use of the Company's office premise. As a result of adopting the new standard, the Company recognized a right-of-use asset of $26,029. The right-of-use asset was measured at an amount equal to the lease liability on adoption. New accounting policy for leases under IFRS 16 Leases At inception of a contract, an assessment is made as to 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. At the commencement date of a lease, a right-of-use asset and a lease liability are recognized. The right-of-use asset is initially measured at cost, which is comprised of the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, less any lease incentives received. A lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by the interest rate implicit in the lease, or if that rate cannot be readily determined, the incremental borrowing rate. The lease obligation is measured at amortized cost using the effective interest method and remeasured if there is a change in future lease payments. The right-of-use asset is subsequently depreciated from the commencement date to the earlier of the end of the lease term, or the end of the useful life of the asset. An assessment is made at the end of each reporting period if there is an indication the carrying value of the right-of-use asset is not recoverable. Adoption of IFRIC 23 Uncertainty over Income Tax Treatments The Company adopted IFRIC 23 Uncertainty over Income Tax Treatments (" IFRIC 23
Principles of consolidation	Principles of consolidation These consolidated financial statements include the accounts of the parent company and its subsidiaries after eliminating intercompany balances and transactions. Subsidiaries Subsidiaries are all entities over which the Company has exposure to variable returns from its involvement and has the ability to use power over the investee to affect its returns. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Company controls another entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company until the date on which control ceases.
Foreign currency translation	Foreign currency translation These consolidated financial statements are expressed in Canadian dollars, unless otherwise noted. The functional currency of the Company is the Canadian dollar, which is the currency of the primary economic environment in which the entity operates. The Company's subsidiaries have functional currencies of either the Canadian dollar or the United States ("US") dollar depending on the currency of the primary environment where the entity operates. Determination of functional currency may involve certain judgements to determine the primary economic environment. Transactions in currencies other than the functional currency are recorded at exchange rates prevailing on the dates of the transactions. At the end of each reporting period, the monetary assets and liabilities of the Company that are denominated in foreign currencies are translated at the rate of exchange at the reporting date while non-monetary assets and liabilities are translated at historical rates. Revenues and expenses are translated at the exchange rates approximating those in effect on the date of the transactions. Exchange gains and losses arising on translation are included in the consolidated statement of loss and comprehensive loss. On translation of the entity whose functional currency is the US dollar, revenues and expenses are translated at the exchange rates approximating those in effect on the date of the transactions. Assets and liabilities are translated at the rate of exchange at the reporting date. Exchange gains and losses, including results of re-translation, are recorded in the foreign currency translation adjustment.
Royalty, stream, and other interests	Royalty, stream, and other interests Royalty, stream, and other interests consist of acquired royalty, stream, and other interests. These interests are recorded at cost and capitalized as tangible assets with finite lives. They are subsequently measured at cost less accumulated depletion and accumulated impairment losses, if any. Project evaluation costs that are not related to a specific royalty or stream asset are expensed in the period incurred. Producing royalty and stream interests are depleted using the units-of-production method over the life of the property to which the interest relates, which is estimated using available information of proven and probable reserves and the portion of resources expected to be classified as mineral reserves at the mine corresponding to the specific agreement. On acquisition of a royalty or stream interest, an allocation of its fair value may be attributed to the exploration potential of the interest and is recorded as an exploration asset on the acquisition date. The carrying value of the exploration potential is accounted for in accordance with IFRS 6 Exploration and Evaluation of Mineral Resources (“IFRS 6”) and is not depleted until such time as the technical feasibility and commercial viability have been established, at which point the value of the asset is accounted for in accordance with IAS 16 Property, Plant and Equipment (“IAS 16”). Upon demonstration of the technical and commercial feasibility of a project and a development decision, the carrying value related to that project is subject to an impairment test and is reclassified in accordance with IAS 16.
Joint operations	Joint operations Under IFRS 11 Joint Arrangements investments in joint arrangements are classified as either joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. The Company recognizes its direct right to the assets, liabilities, revenues, and expenses of joint operations and its share of any jointly held or incurred assets, liabilities, revenues, and expenses.
Investments in associates	Investments in associates Companies over which the Company has significant influence, but not control, are determined to be associates and accounted for using the equity basis of accounting, whereby the investment is initially recorded at cost, adjusted to recognize the Company's share of earnings or losses and reduced by dividends received. The Company assesses its equity investments for impairment if there is objective evidence of impairment as a result of one or more events that occurred after the initial recognition of the equity investment and if the event or events have an impact on the estimated future cash flow of the investment. Objective evidence of impairment of an equity investment includes: • Significant financial difficulty of the associated companies; • Becoming probable that the associated companies will enter bankruptcy or other financial reorganization; or • National or local economic conditions that correlate with defaults of the associated companies.
Impairment of non-financial assets	Impairment of royalty, stream, and other interests The carrying amounts of non-financial assets, excluding deferred income tax assets, are reviewed for impairment at each reporting date, or whenever events or changes in circumstances indicate the carrying amounts may not be recoverable. If there are indicators of impairment, a review is undertaken to determine whether the carrying amounts are in excess of their recoverable amounts. Reviews are undertaken on an asset-by-asset basis, except where the recoverable amount for an individual asset cannot be determined, in which case the review is undertaken at the cash-generating unit (“CGU”) level. If the carrying amount of a CGU or non-financial asset exceeds the recoverable amount, being the higher of its fair value less costs to sell and its value-in-use, an impairment loss is recognized in net loss as the excess of the carrying amount over the recoverable amount. With respect to CGUs, impairment loses are allocated to reduce the carrying amounts of the assets of the CGU on a pro-rata basis. The future cash flow expected is derived using estimates of proven and probable reserves, a portion of resources that is expected to be converted into reserves and information regarding the Company's royalty, stream, and other production-based interests, respectively, that could affect the future recoverability of the Company's interests. Discount factors are determined individually for each asset and reflect their respective risk profiles. In certain circumstances, the Company may use a market approach in determining the recoverable amount which may include an estimate of (a) net present value of estimated future cash flows; (b) dollar value per ounce or pound of reserve/resource; (c) cash-flow multiples; and/or (d) market capitalization of comparable assets. Non-financial assets that have previously been impaired are tested for a possible reversal of the impairment whenever events or changes in circumstances indicate that the impairment may have reversed, or may have partially reversed. In these instances, the impairment loss is reversed to the recoverable amount but not beyond the carrying amount, net of amortization, that would have arisen if the prior impairment loss had not been recognized.
Revenue recognition	Revenue recognition Revenue is comprised of revenue earned in the year from royalty, stream, and other interests. The Company recognizes revenue upon the transfer of control of the relevant commodity to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those commodities. For stream interests, revenue recognition occurs when the relevant commodity received from the stream operator is delivered by the Company to its third-party customers. Revenue is measured at the fair value of the consideration received or receivable when management can reliably estimate the amount, pursuant to the terms of the sales contract. For royalty interests, revenue recognition occurs when control of the relevant commodity is transferred to the end customer by the operator of the royalty property. Revenue is measured at the fair value of the consideration received or receivable when management can reliably estimate the amount, pursuant to the terms of the royalty agreement. In some instances, the Company will not have access to sufficient information to make a reasonable estimate of consideration to which it expects to be entitled and, accordingly, revenue recognition is deferred until management can make a reasonable estimate. Differences between estimates and actual amounts are adjusted and recorded in the period that the actual amounts are known.
Financial instruments	Financial instruments All financial instruments are initially recorded at fair value and designated as follows: Cash includes cash on account and is subsequently measured at amortized cost. Trade receivables relate to amounts received from sales of refined gold and silver and royalty revenue. These receivables are non-interest bearing and are recognized at fair value and are subsequently measured at amortized cost. We have applied the simplified approach to determining expected credit losses, which requires expected lifetime losses to be recognized upon initial recognition of the receivables. Marketable securities are designated as fair value through profit and loss (" FVTPL FVOCI Accounts payables, accrued liabilities, and loans payable are initially recorded at fair value, less transaction costs. These financial liabilities are subsequently measured at amortized cost, calculated using the effective interest rate method
Related party transactions	Related party transactions Parties are considered related if one party has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Parties are also considered related if they are subject to common control or significant influence. A transaction is considered a related party transaction when there is a transfer of resources or obligations between related parties.
Share capital	Share capital Common shares issued for non-monetary consideration are recorded at their fair value based on closing price on the measurement date and classified as equity. The measurement date is defined as the earliest of the date at which the commitment for performance by the counterparty to earn the common shares is reached or the date at which the counterparty's performance is complete. The proceeds from the issue of units are allocated between common shares and share purchase warrants on a pro-rata basis based on the relative fair values. The fair value of the common shares is based on the market closing price on the date of issuance and the fair value of the share purchase warrants is determined using the Black-Scholes option pricing model. Transaction costs directly attributable to the issue of common shares are recognized as a deduction from equity, net of any tax effects.
Earnings (loss) per share	Earnings (loss) per share The Company presents basic earnings (loss) per share data for its common shares, calculated by dividing the income (loss) attributable to equity holders of the Company by the weighted average number of common shares issued and outstanding during the period. Diluted earnings per share is calculated by adjusting the earnings attributable to equity holders and the weighted average number of common shares outstanding for the effects of all potentially dilutive common shares. The calculation of diluted earnings per share assumes that the proceeds to be received on the exercise of dilutive share options and warrants are used to repurchase common shares at the average market price during the period. In periods where a loss is reported, diluted loss per share is the same as basic loss per share as the effects of potentially dilutive common shares would be anti-dilutive.
Income taxes	Income taxes Income tax expense consists of current and deferred tax expense. Income tax expense is recognized in the consolidated statement of loss and comprehensive loss. Current tax expense is the expected tax payable on the taxable income for the period, using tax rates enacted or substantively enacted at period end, adjusted for amendments to tax payable with regards to previous periods. Deferred tax assets and liabilities are recognized for deferred tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and losses carried forward. 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 income in the period that 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. To the extent that the Company does not consider it probable that a deferred tax asset will be recovered, the deferred tax asset is reduced. Deferred tax assets and liabilities are offset when there is a legally enforceable right to offset 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 current tax assets and liabilities on a net basis.
Share-based payments	Share-based payments The Company grants stock options and restricted share units (" RSUs The fair value method of accounting is used for share-based payment transactions. Under this method, the cost of stock options and other equity-settled share-based payment arrangements are recorded based on the estimated fair value at the grant date and charged to earnings over the vesting period. Where awards are forfeited because non-market based vesting conditions are not satisfied, the expense previously recognized is proportionately reversed in the period the forfeiture occurs.
Segment reporting	Segment reporting Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision-maker. The chief operating decision-maker, who is responsible for allocating resources and assessing performance of the operating segment, has been identified as the Chief Executive Officer ("CEO"). The Company operates in a single segment, the acquisition and management of precious metal royalties, streams, and similar production-based interests. In addition, the Company has corporate activities, which include the evaluation and acquisition of new precious metal royalties, streams, and similar production-based interests, treasury and finance, regulatory reporting, and corporate administration.
Critical accounting estimates and judgments	Critical accounting estimates and judgments The preparation of the Company’s consolidated financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the reported amounts of assets, liabilities and contingent liabilities at the date of the consolidated financial statements and reported amounts of revenues and expenses during the reporting period. Estimates and assumptions are continuously evaluated and are based on management’s experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. However, actual outcomes can differ from these estimates. Information about significant areas of estimation uncertainty and judgments made by management in preparing the consolidated financial statements are described below. The preparation of consolidated financial statements in conformance with IFRS requires management to make estimates, judgments and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue, and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected. Critical accounting estimates are estimates and assumptions made by management that may result in a material adjustment to the carrying amount of assets and liabilities within the next financial year and include, but are not limited to, the following: a) Royalty interests The Company holds royalty interests in production stage mineral properties. The royalty interests are recorded initially at their costs and are being depleted using the units of production basis over the expected life of the related mineral property, which is determined using available estimates of future metal prices and future production. Proven and probable reserves and future production plans associated with the royalty interests as determined by the operators impact the measurement of the respective assets. These estimates affect the depletion of the royalty interests and the assessment of the recoverability of the carrying value of the royalty interests. Management considers both external and internal sources of information in assessing whether there are any indications that the Company’s royalty interests are impaired. External sources of information management considers include changes in the market, economic and legal environment in which the Company operates that are not within its control and affect the recoverable amount of its royalty interests. Internal sources of information that management considers include the indications of economic performance of the assets. In determining the recoverable amounts of the Company’s royalty interests, management makes estimates of the discounted net cash flows expected to be derived from the Company’s royalty interests, costs of disposal, and the appropriate discount rates and discount multiples that apply to the specific asset. Reductions in metal price forecasts, increases in estimated future costs of production for the mine operators, reductions in the amount of recoverable mineral reserves, mineral resources, and exploration potential, and/or adverse current economics can result in a write-down of the carrying amounts of the Company’s royalty interests. b) Estimation of depletion The Company’s royalty, stream, and other production-based interests that generate economic benefits are considered depletable and are depleted on a unit-of-production basis over the ounces of production that are expected to generate the cash flows that will be attributable to the Company. These calculations require the use of estimates and assumptions, including the amount of contained metals, the recovery rates, and payable rates for the contained metals being treated through a milling or refining process. Changes to these assumptions may impact the estimated recoverable reserves, resources or exploration potential which could directly impact the depletion rates used. Changes to depletion rates are accounted for prospectively. c) Income taxes The interpretation of existing tax laws or regulations in Canada, Australia, Argentina, the United States, or any of the countries in which our property interests are located requires the use of judgment. Differing interpretation of these laws or regulations could result in an increase in the Company's taxes, or other governmental charges, duties or impositions. In addition, the recoverability of deferred income tax assets, including expected periods of reversal of temporary differences and expectations of future taxable income, are assessed by management at the end of each reporting period and adjusted, as necessary, on a prospective basis.
