Summary of Significant Accounting Policies	2 – Summary of Significant Accounting Policies A. Statement of Compliance These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). B. Basis of Presentation These consolidated financial statements have been prepared on a historical cost basis except for certain financial instruments, which are measured at fair value or amortized cost. The consolidated financial statements are presented in United States dollars, and all values are rounded to the nearest thousand except as otherwise indicated. C. Principles of Consolidation These consolidated financial statements include the accounts of the Company and its subsidiaries (all wholly owned), Sandstorm Gold (Canada) Ltd., Bridgeport Gold Inc., Inversiones Mineras Australes Holdings (BVI) Inc., Inversiones Mineras Australes S.A., Premier Royalty U.S.A. Inc., SA Targeted Investing Corp., Sandstorm Metals & Energy (Canada) Holdings Ltd., Sandstorm Metals & Energy (Canada) Ltd., Sandstorm Metals & Energy (US) Inc., Mariana Resources Limited and Mariana Turkey Limited. Subsidiaries are fully consolidated from the date the Company obtains control and continue to be consolidated until the date that control ceases. Control is achieved when the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. All intercompany balances, transactions, revenues and expenses have been eliminated on consolidation. D. Business Combinations On the acquisition of a business, the acquisition method of accounting is used, whereby the purchase consideration is allocated to the identifiable assets and liabilities on the basis of fair value at the date of acquisition. Provisional fair values allocated at a reporting date are finalized as soon as the relevant information is available, within a period not to exceed twelve months from the acquisition date with retrospective restatement of the impact of adjustments to those provisional fair values effective as at the acquisition date. Incremental costs related to acquisitions are expensed as incurred. When the amount of purchase consideration is contingent on future events, the initial cost of the acquisition recorded includes an estimate of the fair value of the contingent amounts expected to be payable in the future. When the fair value of contingent consideration as at the date of acquisition is finalized before the purchase price allocation is finalized, the adjustment is allocated to the identifiable assets and liabilities acquired. Subsequent changes to the estimated fair value of contingent consideration are recorded in the Consolidated Statements of Income (Loss). When the cost of the acquisition exceeds the fair values of the identifiable net assets acquired, the difference is recorded as goodwill. If the fair value attributable to the Company’s share of the identifiable net assets exceeds the cost of acquisition, the difference is recognized as a gain in the Consolidated Statements of Income (Loss). Non-controlling E. Investment in Associate An associate is an entity over which the Company has significant influence and is neither a subsidiary nor a joint arrangement. The Company has significant influence when it has the power to participate in the financial and operating policy decisions of the associate but does not have control or joint control over those policies. The Hod Maden interest on the Company’s Consolidated Statements of Financial Position represents an investment in an associate. The Company accounts for its investment in an associate using the equity method. Under the equity method, the Company’s investment in an associate is initially recognized at cost when acquired and subsequently increased or decreased to recognize the Company’s share of net income and losses of the associate, after any adjustments necessary to give effect to uniform accounting policies, any other movement in the associate’s reserves, and for impairment losses after the initial recognition date. The Company’s share of income and losses of the associate is recognized in net income during the period. Dividends received from the associate are accounted for as a reduction in the carrying amount of the Company’s investment. F. Goodwill The Company allocates goodwill arising from business combinations to each cash-generating unit or group of cash-generating units that are expected to receive the benefits from the business combination. Irrespective of any indication of impairment, the recoverable amount of the cash-generating unit or group of cash-generating units to which goodwill has been allocated is tested annually for impairment and when there is an indication that the goodwill may be impaired. Any impairment is recognized as an expense immediately. Any impairment of goodwill is not subsequently reversed. G. Mineral, Royalty and Other Interests Mineral, royalty and other interests consist of acquired royalty interests and stream metal purchase agreements. 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 agreement are expensed in the period incurred. Producing mineral, royalty and other interests are depleted using the units-of-production On acquisition of a mineral, royalty or other interest, an allocation of its cost is attributed to the exploration potential of the interest and is recorded as an asset on the acquisition date. The value of the exploration potential is accounted for in accordance with IFRS 6, Exploration and Evaluation of Mineral Resources 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. H. Impairment of Mineral, Royalty and Other Interests Evaluation of the carrying values of each mineral property is undertaken when events or changes in circumstances indicate that the carrying values may not be recoverable and at each reporting period. If any indication of impairment exists, the recoverable amount is estimated to determine the extent of any impairment loss. The recoverable amount is the higher of the fair value less costs of disposal and value in use. Fair value is the price that would be received from selling an asset in an orderly transaction between market participants at the measurement date. Costs of disposal are incremental costs directly attributable to the disposal of an asset. Fair value less costs of disposal is usually estimated using a discounted cash flow approach. Estimated future cash flows are calculated using estimated production, sales prices, and a discount rate. Estimated production is determined using current reserves and the portion of resources expected to be classified as mineral reserves as well as exploration potential expected to be converted into resources. Estimated sales prices are determined by reference to an average of long-term metal price forecasts by analysts and management’s expectations. The discount rate is estimated using an average discount rate incorporating analyst views to value precious metal royalty companies. Value in use is determined as the future value of present cash flows expected to be derived from continuing use of an asset in its present form for those assets where value in use exceeds fair value less costs of disposal. If it is determined that the recoverable amount is less than the carrying value, then an impairment is recognized within net income (loss) immediately. An assessment is made at each reporting period if there is any indication that a previous impairment loss may no longer exist or has decreased. If indications are present, the carrying amount of the mineral interest is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount net of depletion that would have been determined had no impairment loss been recognized for the mineral interest in previous periods. I. Exploration Assets All costs incurred prior to obtaining the legal right to undertake exploration and evaluation activities on a project are expensed in the period incurred. Exploration and evaluation costs arising following the acquisition of an exploration license are capitalized on a project-by-project Upon demonstration of the technical and commercial feasibility of a project and a development decision, any past exploration and evaluation costs related to that project are subject to an impairment test and are reclassified in accordance with IAS 16, Property Plant and Equipment. Management assesses exploration assets for impairment at each reporting period or when facts and circumstances suggest that the carrying value of capitalized exploration costs may not be recoverable. J. Revenue Recognition Revenue is comprised of revenue earned in the period from contracts with customers under each of its royalty and mineral stream interests. The Company has determined that each unit of a commodity that is delivered to a customer under a royalty and mineral stream interest arrangement is a performance obligation for the delivery of a good that is separate from each other unit of the commodity to be delivered under the same arrangement. In accordance with IFRS 15, the Company recognizes revenue to depict the transfer 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 agreements, revenue recognition occurs when the relevant commodity received from the stream operator is transferred by the Company to its third-party customers. For royalty interests, revenue recognition occurs when 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. K. Foreign Currency Translation The functional currency of the Company and its subsidiaries is the principal currency of the economic environment in which they operate. For the Company and its subsidiaries Sandstorm Gold (Canada) Ltd., Bridgeport Gold Inc., Inversiones Mineras Australes S.A., Inversiones Mineras Australes Holdings (BVI) Inc., Premier Royalty U.S.A. Inc., SA Targeted Investing Corp., Sandstorm Metals & Energy (Canada) Holdings Ltd., Sandstorm Metals & Energy (Canada) Ltd., Sandstorm Metals & Energy (US) Inc., Mariana Resources Limited and Mariana Turkey Limited the functional currency is the U.S. dollar. The functional currency of the Company’s Hod Maden interest in associate is the Turkish Lira. To translate the Hod Maden interest to the presentation currency of the U.S. dollar, all assets and liabilities are translated using the exchange rate as of the reporting date and all income and expenses are translated using the average exchange rates during the period. All resulting exchange differences are recognized in other comprehensive income (loss). Transactions in foreign currencies are initially recorded in the entity’s functional currency as the rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated using the closing rate as at the reporting date. L. Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, trade receivables and other, short and long-term investments, loans receivable which are included in other current assets, trade and other payables and bank debt. All financial instruments are initially recorded at fair value and designated as follows: Cash and cash equivalents, trade receivables and other, and loans receivable which are included in other current assets are classified as financial assets at amortized cost and trade and other payables and bank debt are classified as financial liabilities at amortized cost. Both financial assets at amortized cost and financial liabilities at amortized cost are measured at amortized cost using the effective interest method. The company’s financial assets which are subject to credit risk include cash and cash equivalents, trade receivables and other and loans receivable which are included in other current assets. Application of the expected credit loss model at the date of adoption did not have a significant impact on the Company’s financial assets because the Company determined that the expected credit losses on its financial assets were nominal. There were no impairment losses recognized on financial assets during the years ended December 31, 2019 and December 31, 2018. Investments in common shares are held for long-term strategic purposes and not for trading. The Company has made an irrevocable election to designate all these investments as fair value through other comprehensive income (“FVTOCI”) in order to provide a more meaningful presentation based on management’s intention, rather than reflecting changes in fair value in net income. Such investments are measured at fair value at the end of each reporting period, with any gains or losses arising on re-measurement Investments in warrants and convertible debt instruments are classified as fair value through profit or loss (“FVTPL”). These warrants and convertible debt instruments are measured at fair value at the end of each reporting period, with any gains or losses arising on re-measurement Transaction costs on initial recognition of financial instruments classified as FVTPL are expensed as incurred. Transaction costs incurred on initial recognition of financial instruments classified as loans and receivables, FVTOCI and other financial liabilities are recognized at their fair value amount and offset against the related loans and receivables or capitalized when appropriate. Financial assets are derecognized when the contractual rights to the cash flows from the asset expire. Financial liabilities are derecognized only when the Company’s obligations are discharged, cancelled or they expire. On derecognition, the difference between the carrying amount (measured at the date of derecognition) and the consideration received (including any new asset obtained less any new liability obtained) is recognized in profit or loss. M. Inventory When refined gold or the applicable commodity, under the Stream agreement, is delivered to the Company, it is recorded as inventory. The amount recognized as inventory includes both the cash payment and the related depletion associated with the related mineral interest. N. Cash and Cash Equivalents Cash and cash equivalents include cash on account, demand deposits and money market investments with maturities from the date of acquisition of three months or less, which are readily convertible to known amounts of cash and are subject to insignificant changes in value. O. Income Taxes Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used are those that are substantively enacted at the reporting date. Deferred income taxes are provided using the liability method on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for accounting. The change in the net deferred income tax asset or liability is included in income except for deferred income tax relating to equity items which is recognized directly in equity, and relating to investments in common shares designed as FVTOCI which is recognized in other comprehensive income. The income tax effects of differences in the periods when revenue and expenses are recognized in accordance with Company accounting practices, and the periods they are recognized for income tax purposes are reflected as deferred income tax assets or liabilities. Deferred income tax assets and liabilities are measured using the substantively enacted statutory income tax rates which are expected to apply to taxable income in the years in which the assets are realized or the liabilities settled. 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 for utilization. Deferred income tax assets and liabilities are offset only if a legally enforceable right exists to offset current tax assets against liabilities and the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on the same taxable entity and are intended to be settled on a net basis. The determination of current and deferred taxes requires interpretations of tax legislation, estimates of expected timing of reversal of deferred tax assets and liabilities, and estimates of future earnings. P. Share Capital and Share Purchase Warrants The proceeds from the issue of units are allocated between common shares and share purchase warrants (with an exercise price denominated in U.S. dollars) on a pro-rata Q. Earnings Per Share Basic earnings per share is computed by dividing the net income available to common shareholders by the weighted average number of common shares issued and outstanding during the period. Diluted earnings per share is calculated assuming that outstanding share options and share purchase warrants, with an average market price that exceeds the average exercise prices of the options and warrants for the year, are exercised and the proceeds are used to repurchase shares of the Company at the average market price of the common shares for the year. R. Share Based Payments The Company recognizes share based compensation expense for all share purchase options and restricted share rights (“RSRs”) awarded to employees, officers and directors based on the fair values of the share purchase options and RSRs at the date of grant. The fair values of share purchase options and RSRs at the date of grant are expensed over the vesting periods of the share purchase options and RSRs, respectively, with a corresponding increase to equity. The fair value of share purchase options is determined using the BSM with market related inputs as of the date of grant. Share purchase options with graded vesting schedules are accounted for as separate grants with different vesting periods and fair values. The fair value of RSRs is the market value of the underlying shares at the date of grant. At the end of each reporting period, the Company re-assesses The BSM requires management to estimate the expected volatility and expected term of the equity instrument, the risk-free rate of return over the term, expected dividends, and the number of equity instruments expected to ultimately vest. The Company uses its competitors market data with respect to expected volatility and expected dividend yield to the extent these factors are indicative of the Company’s future expectations. The expected term is estimated using historical exercise data, and the number of equity instruments expected to vest is estimated using historical forfeiture data. S. 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. T. Segment Reporting An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses. The Company’s operating segments are components of the Company’s business for which discrete financial information is available and which are reviewed regularly by the Company’s Chief Executive Officer to make decisions about resources to be allocated to the segment and assess its performance. U. Leases Upon lease commencement, the Company recognizes a right-of-use right-of-use re-measured

New Accounting Policies and Future Changes in Accounting Policies	3 – New Accounting Policies and Future Changes in Accounting Policies ADOPTION OF IFRS 16: LEASES IFRS 16 establishes a comprehensive framework for recognition, measurement and classification of leases and requires lessees to recognize assets and liabilities for most leases. It has replaced International Accounting Standard (“IAS”) 17 Leases and related interpretations. The Company has adopted IFRS 16 retrospectively from January 1, 2019 and has not restated comparatives for the 2018 reporting period, as permitted under the specific transitional provisions in the standard. The reclassifications and adjustments arising from the new leasing rules are recognized on the opening statement of financial position on January 1, 2019 to the extent they arise; however, no adjustments were necessary to the Company’s opening retained earnings as a result of the adoption of this standard. With respect to the Company’s office leases, a $3 million right-of-use non-current On adoption of IFRS 16, the Company recognized lease liabilities in relation to leases which had previously been classified as operating leases under the principles of IAS 17 Leases. These liabilities were measured at the present value of the remaining lease payments, discounted using the Company’s incremental borrowing rate as of January 1, 2019. The associated right-of-use IFRIC INTERPRETATION 23: UNCERTAINTY OVER INCOME TAX TREATMENTS In June 2017, the IASB issued IFRS Interpretations Committee (“IFRIC”) Interpretation 23 Uncertainty over Income Tax Treatments, which is applied to the determination of taxable profit or loss, unused tax losses, unused tax credits, tax rates and tax bases, when there is uncertainty about income tax treatment under IAS 12 Income Taxes. IFRIC 23 is effective January 1, 2019 and is to be applied retrospectively. The new standard did not have a material impact on the Company’s consolidated financial statements.

Key Sources of Estimation Uncertainty and Critical Accounting Judgments	4 – Key Sources of Estimation Uncertainty and Critical Accounting 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 sources of estimation uncertainty and judgments made by management in preparing the consolidated financial statements are described below. A. Attributable Reserve and Resource Estimates Mineral, royalty and other interests are a significant class of assets of the Company, with a carrying value of $395.5 million at December 31, 2019 (2018 - $374.2 million). This amount represents the capitalized expenditures related to the acquisition of the mineral, royalty and other interests net of accumulated depletion and any impairments. The Company estimates the reserves and resources relating to each agreement. Reserves and Resources are estimates of the amount of minerals that can be economically and legally extracted from the mining properties at which the Company has stream and royalty agreements, adjusted where applicable to reflect the Company’s percentage entitlement to minerals produced from such mines. The public disclosures of Reserves and Resources that are released by the operators of the interests involve assessments of geological and geophysical studies and economic data and the reliance on a number of assumptions, including commodity prices and production costs. The estimates of Reserves and Resources may change based on additional knowledge gained subsequent to the initial assessment. Changes in the Reserve or Resource estimates may impact the carrying value of the Company’s mineral, royalty and other interests and depletion charges. The Company’s mineral and royalty interests are depleted on a units-of-production B. Investments In the normal course of operations, the Company invests in equity interests of other entities. In such circumstances, management considers whether the facts and circumstances pertaining to each such investment result in the Company obtaining control, joint control or significant influence over the investee entity. In some cases, the determination of whether or not the Company controls, jointly controls or significantly influences the investee entities requires the application of significant management judgment to consider individually and collectively such factors as: · The purpose and design of the investee entity. · The ability to exercise power, through substantive rights, over the activities of the investee entity that significantly affect its returns. · The size of the Company’s equity ownership and voting rights, including potential voting rights. · The size and dispersion of other voting interests, including the existence of voting blocks. · Other investments in or relationships with the investee entity including, but not limited to, current or possible board representation, royalty and/or stream investments, loans and other types of financial support, material transactions with the investee entity, interchange of managerial personnel or consulting positions. · Other relevant and pertinent factors. If it is determined that the Company neither has control, joint control or significant influence over an investee entity, the Company accounts for the corresponding investment in equity interest at fair value through other comprehensive income as further described in note 2. C. Income Taxes The interpretation of existing tax laws or regulations in Canada, the United States of America, Australia, Argentina, Chile, Ecuador, Turkey, Guernsey, Mexico or any of the countries in which the mining operations are located or to which shipments of gold and other metals are made 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. To the extent there are uncertain tax provisions, the Company measures the impact of the uncertainty using the method that best predicts the resolution of the uncertainty. The judgements and estimates made to recognize and measure the effect of uncertain tax treatments are reassessed whenever circumstances change or when there is new information that affects those judgements. 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. Refer to note 11 for more information. D. Impairment of Assets There is judgment required to determine whether any indication of impairment exists at the end of each reporting period for each mineral, royalty and other interest and the Hod Maden interest, including assessing whether there are observable indications that the asset’s value has declined during the period. Management uses judgment when assessing whether there are indicators of impairment, such as significant changes in future commodity prices, discount rates, operator reserve and resource estimates or other relevant information received from the operators that indicates production from mineral interests will not likely occur or may be significantly reduced in the future. If such an indication exists, the recoverable amount of the interest is estimated in order to determine the extent of the impairment (if any). The recoverable amount is the higher of the fair value less costs of disposal and value in use. The calculation of the recoverable amount requires the use of estimates and assumptions such as long-term commodity prices, discount rates, and operating performance. The recoverable amount is determined by calculating the present value of expected future cash flows. The discount rate is based on the Company’s weighted average cost of capital, adjusted for various risks. The expected future cash flows are management’s best estimates of expected future revenues and costs. Under each method, expected future revenues reflect the estimated future production for each mine at which the Company has a Gold Stream or royalty based on detailed life of mine plans received from each of the mine operators. Included in these forecasts is the production of mineral resources that do not currently qualify for inclusion in proven and probable ore reserves where there is a high degree of confidence in its economic extraction. This is consistent with the methodology that is used to measure value beyond proven and probable reserves when determining the fair value attributable to acquired mineral and royalty interests. Expected future revenues also reflect management’s estimated long term metal prices, which are determined based on current prices, forward pricing curves and forecasts of expected long-term metal prices prepared by analysts. These estimates often differ from current price levels, but are consistent with how a market participant would assess future long-term metal prices. Estimated future cash costs are established based on the terms of each Gold Stream, Stream, or royalty, as disclosed in note 15 to the financial statements. E. Accounting for Acquisition of Assets and Mineral Interests The Company’s business is the acquisition of Gold Streams, Streams, and royalties. Each mineral, royalty and other interest agreement has its own unique terms and judgement is required to assess the appropriate accounting treatment. The determination of whether an acquisition should be accounted for as a mineral, royalty and other interest or a financial instrument requires the consideration of factors such as (i) the terms of the agreement; (ii) the applicability of the own use exemption under IFRS 9; (iii) whether there is a contractual commitment to repay amounts under the Stream; and (iv) the expected timing and amount of future deliveries of gold, silver and other commodities under the Stream with reference to the existing mine plan. The assessment of whether an acquisition meets the definition of a business or whether assets are acquired is another area of key judgement. If deemed to be a business combination, applying the acquisition method to business combinations requires each identifiable asset and liability to be measured at its acquisition date fair value. The excess, if any, of the fair value of the consideration over the fair value of the net identifiable assets acquired is recognized as goodwill. The determination of the acquisition date fair values often requires management to make assumptions and estimates about future events. The assumptions and estimates with respect to determining the fair value of mineral, royalty and other interests generally requires a high degree of judgement, and include estimates of mineral reserves and resources acquired, future metal prices, discount rates and conversion of reserves and resources. Changes in any of the assumptions or estimates used in determining the fair value of acquired assets and liabilities could impact the amounts assigned to assets and liabilities. F. Functional Currency The functional currency for each of the Company’s subsidiaries and associates is the currency of the primary economic environment in which the entity operates. Determination of functional currency may involve certain judgments to determine the primary economic environment and the Company reconsiders the functional currency of its entities if there is a change in events and conditions which determined the primary economic environment.

Financial Instruments	5 – Financial Instruments A. Capital Risk Management The Company manages its capital such that it endeavors to continue as a going concern while maximizing the return to stakeholders through the optimization of the debt and equity balance. At December 31, 2019, the capital structure of the Company consists of $570.9 million (2018 - $583.4 million) of equity attributable to common shareholders, comprising of issued capital (note 10), accumulated reserves, deficit and accumulated other comprehensive income (loss). The Company was not subject to any externally imposed capital requirements with the exception of complying with certain covenants under the credit agreement governing bank debt. The Company is in compliance with the debt covenants described in note 9 as at December 31, 2019. B. Fair Value Estimation The fair value hierarchy establishes three levels to classify the inputs of valuation techniques used to measure fair value. As required by IFRS 13, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy are described below: Level 1 | Level 2 | Level 3 | The following table sets forth the Company’s financial assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy as at December 31, 2019 and December 31, 2018. As at December 31, 2019: In $000s Total Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Short-term investments Convertible debt $ 10,801 $ - $ 10,801 $ - Long-term investments Common shares held $ 52,325 $ 52,325 $ - $ - Warrants and other 4,623 - 4,623 - Convertible debt 15,892 - 15,892 - $ 83,641 $ 52,325 $ 31,316 $ - As at December 31, 2018: In $000s Total Quoted prices in active markets for identical assets (Level 1) Significant other observable inputs (Level 2) Significant unobservable inputs (Level 3) Short-term investments Convertible debt $ 13,937 $ - $ 13,937 $ - Long-term investments Common shares held $ 33,139 $ 33,139 $ - $ - Warrants and other 2,106 - 2,106 - Convertible debt 10,998 - 10,998 - $ 60,180 $ 33,139 $ 27,041 $ - The fair value of the Company’s other financial instruments which include cash and cash equivalents, trade and other receivables, loans receivable which are included in other assets, and trade and other payables approximate their carrying values at December 31, 2019 and December 31, 2018 due to their short-term nature. The fair value of the Company’s bank debt approximates its carrying value due to the nature of its market-based rate of interest. There were no transfers between the levels of the fair value hierarchy during the years ended December 31, 2019 and December 31, 2018. C. Credit Risk The Company’s credit risk is limited to cash and cash equivalents, loans receivable which are included in other assets, trade and other receivables and the Company’s investments in convertible debentures. The Company’s trade and other receivables is subject to the credit risk of the counterparties who own and operate the mines underlying Sandstorm’s royalty portfolio. In order to mitigate its exposure to credit risk, the Company closely monitors its financial assets and maintains its cash deposits in several high-quality financial institutions. The Company’s investments in convertible debentures are subject to the counterparties’ credit risk. In particular, the Company’s convertible debentures due from Equinox Gold Corp. (“Equinox”) and Americas Gold (defined herein) is subject to the respective counterparty credit risk and the Company’s ability to realize on its security. Furthermore, the convertible debenture due from Equinox is subject to the risk that the value of Equinox’s equity decreases below the puttable price of the instrument. The impact of expected credit losses on trade receivables and financial assets held at amortized cost is not material. D. Currency Risk Financial instruments that impact the Company’s net income or other comprehensive income due to currency fluctuations include: cash and cash equivalents, trade and other receivables and trade and other payables denominated in Canadian dollars. Based on the Company’s Canadian dollar denominated monetary assets and monetary liabilities at December 31, 2019 a 10% increase (decrease) of the value of the Canadian dollar relative to the United States dollar would not have a material impact on net income or other comprehensive income. E. Liquidity Risk The Company has in place a planning and budgeting process to help determine the funds required to support the Company’s normal operating requirements on an ongoing basis. In managing liquidity risk, the Company takes into account the amount available under the Company’s revolving credit facility, anticipated cash flows from operating activities and its holding of cash and cash equivalents. As at December 31, 2019, the Company had cash and cash equivalents of $7.0 million (December 31, 2018 – $5.9 million). Sandstorm holds common shares, convertible debentures, and warrants and other of other companies with a combined fair market value as at December 31, 2019, of $83.6 million (December 31, 2018 – $60.2 million). The daily exchange traded volume of these shares, including the shares underlying the warrants, may not be sufficient for the Company to liquidate its position in a short period of time without potentially affecting the market value of the shares. F. Other Price Risk The Company is exposed to equity price risk as a result of holding investments in other mining companies. The Company does not actively trade these investments. The equity prices of long term investments are impacted by various underlying factors including commodity prices. Based on the Company’s investments held as at December 31, 2019 a 10% increase (decrease) in the equity prices of these investments would increase (decrease) net income by $1.6 million and other comprehensive income by $5.2 million.

B. Significant updates and other transactions During the year ended December 31, 2019: FRUTA DEL NORTE On January 18, 2019, the Company acquired a 0.9% NSR royalty on precious metals produced from the Fruta del Norte gold project in Ecuador, currently under construction by Lundin Gold Inc. The NSR royalty was acquired from a private third party for $32.8 million in cash and covers all mining concessions held by Lundin Gold Inc. on the Fruta del Norte gold project. RELIEF CANYON On April 3, 2019, the Company entered into a $42.5 million financing package with Americas Gold and Silver Corp. (“Americas Gold”) which includes a $25 million precious metal stream and an NSR on the Relief Canyon gold project in Nevada, U.S.A. (“Relief Canyon” or the “Relief Canyon Project”), a $10 million convertible debenture and a $7.5 million private placement. Under the terms of the precious metals stream, Sandstorm is entitled to receive 32,022 ounces of gold over a 5.5 year period beginning in April 2020 (the “Fixed Deliveries”). Under certain conditions, the starting date under the Fixed Deliveries may be extended by up to six months. After receipt of the Fixed Deliveries, the Company is entitled to purchase 4% of the gold and silver produced from the Relief Canyon Project for ongoing per ounce cash payments equal to 30%-65% 1.4%-2.8% Americas Gold may elect to reduce the 4.0% Stream and NSR on the Relief Canyon Project by delivering 4,000 ounces of gold to Sandstorm (the “Purchase Option”). The Purchase Option may be exercised by Americas Gold at any time and is subject to a 10% annual premium. Upon exercising the Purchase Option, the 4.0% Stream will decrease to 2.0% and the NSR will decrease to 1.0%. During the year ended December 31, 2018: HOUNDÉ On January 17, 2018, the Company acquired a 2% net smelter returns royalty (“NSR”) on the producing Houndé gold mine in Burkina Faso, owned and operated by Endeavour Mining Corporation. The royalty was acquired from Acacia Mining PLC for $45 million in cash and covers the Kari North and Kari South tenements. KORICANCHA In August 2018, the Company disposed of its interest in the Koricancha Gold Stream. The fair value of the financial instruments received on disposal amounted to $4.3 million, resulting in a $0.4 million loss. C. Impairments During the year ended December 31, 2019: As a result of a continued decline in the price of diamonds, the Company estimated the recoverable amount of the Diavik royalty and recorded an impairment charge of $2.4 million. The recoverable amount of $19.8 million was determined using a discounted cash flow model in estimating the fair value less costs of disposal. This is a level 3 measurement due to the unobservable inputs in the model. Key assumptions used in the cash flow forecast were: a mine life of approximately 3 years, a diamond price ranging from $110 - $130 per carat and a 4% discount rate. During the year ended December 31, 2018: As a result of an update to the production profile of the Gualcamayo mine and the estimated future ounces expected from the royalty, the Company estimated the recoverable amount of its royalty investment and recorded an impairment charge of $4.5 million ($3.2 million, net of tax). The recoverable amount of $2.5 million was determined using a discounted cash flow model in estimating the fair value less costs of disposal. This is a level 3 measurement due to the unobservable inputs in the model. Key assumptions used in the cash flow forecast were: a 3 year mine life, a gold price of $1,300 and a 4% discount rate .

Share Capital and Reserves	10 – Share Capital and Reserves A. Authorized Share Capital The Company is authorized to issue an unlimited number of common shares without par value. Under the Company’s normal course issuer bid (“NCIB”), the Company is able until April 4, 2020, to purchase up to 13.0 million common shares. The NCIB provides the Company with the option to purchase its common shares from time to time. During the year ended December 31, 2019, the Company, utilizing its previous and current NCIB, purchased and cancelled approximately 8.7 million common shares. B. Stock Options of the Company The Company has an incentive stock option plan (the “Option Plan”) whereby the Company may grant share options to eligible employees, officers, directors and consultants at an exercise price, expiry date, and vesting conditions to be determined by the Board of Directors. The maximum expiry date is five years from the grant date. All options are equity settled. The Option Plan permits the issuance of options which, together with the Company’s other share compensation arrangements, may not exceed 8.5% of the Company’s issued common shares as at the date of the grant. During the year ended December 31, 2019, the Company issued 1,427,000 options with a weighted average exercise price of CAD8.89 and a fair value of $2.0 million or $1.38 per option. The fair value of the options granted was determined using a Black-Scholes model using the following weighted average assumptions: grant date share price and exercise price of CAD8.89, expected volatility of 30%, risk-free interest rate of 1.62% and an expected life of 3 years. Expected volatility was determined by considering the trailing 3 year historic average share price volatility of similar companies in the same industry and business model. A summary of the Company’s options and the changes for the year is as follows: Number of Options Weighted average 1 Options outstanding at December 31, 2017 7,726,317 3.79 Granted 3,130,000 5.92 Exercised (1,440,907) (3.22) Expired unexercised (77,436) (7.19) Forfeited (15,333) (4.96) Options outstanding at December 31, 2018 9,322,641 4.58 Granted 1,427,000 8.89 Exercised (3,181,108) (2.99) Options outstanding at December 31, 2019 7,568,533 6.06 1 For options exercisable in British Pounds Sterling (“GBP”), exercise price is translated to Canadian Dollars (“CAD”) using the period end exchange rate. The weighted-average share price, at the time of exercise, for those shares that were exercised during the year ended December 31, 2019 was CAD7.75 per share (2018 - CAD6.07). The weighted average remaining contractual life of the options as at December 31, 2019 was 3.38 years (2018 - 3.02 years).

D. Restricted Share Rights The Company has a restricted share plan (the “Restricted Share Plan”) whereby the Company may grant restricted share rights (“RSRs”) to eligible employees, officers, directors and consultants at an expiry date to be determined by the Board of Directors. Each restricted share right entitles the holder to receive a common share of the Company without any further consideration. The Restricted Share Plan permits the issuance of up to a maximum of 4,500,000 restricted share rights. During the year ended December 31, 2019, the Company granted 579,700 RSRs with a fair value of $3.9 million, a three year vesting term, and a weighted average grant date fair value of $6.73 per unit.

Business Combinations On the acquisition of a business, the acquisition method of accounting is used, whereby the purchase consideration is allocated to the identifiable assets and liabilities on the basis of fair value at the date of acquisition. Provisional fair values allocated at a reporting date are finalized as soon as the relevant information is available, within a period not to exceed twelve months from the acquisition date with retrospective restatement of the impact of adjustments to those provisional fair values effective as at the acquisition date. Incremental costs related to acquisitions are expensed as incurred. When the amount of purchase consideration is contingent on future events, the initial cost of the acquisition recorded includes an estimate of the fair value of the contingent amounts expected to be payable in the future. When the fair value of contingent consideration as at the date of acquisition is finalized before the purchase price allocation is finalized, the adjustment is allocated to the identifiable assets and liabilities acquired. Subsequent changes to the estimated fair value of contingent consideration are recorded in the Consolidated Statements of Income (Loss). When the cost of the acquisition exceeds the fair values of the identifiable net assets acquired, the difference is recorded as goodwill. If the fair value attributable to the Company’s share of the identifiable net assets exceeds the cost of acquisition, the difference is recognized as a gain in the Consolidated Statements of Income (Loss). Non-controlling
Investment in Associate	E. Investment in Associate An associate is an entity over which the Company has significant influence and is neither a subsidiary nor a joint arrangement. The Company has significant influence when it has the power to participate in the financial and operating policy decisions of the associate but does not have control or joint control over those policies. The Hod Maden interest on the Company’s Consolidated Statements of Financial Position represents an investment in an associate. The Company accounts for its investment in an associate using the equity method. Under the equity method, the Company’s investment in an associate is initially recognized at cost when acquired and subsequently increased or decreased to recognize the Company’s share of net income and losses of the associate, after any adjustments necessary to give effect to uniform accounting policies, any other movement in the associate’s reserves, and for impairment losses after the initial recognition date. The Company’s share of income and losses of the associate is recognized in net income during the period. Dividends received from the associate are accounted for as a reduction in the carrying amount of the Company’s investment.
Goodwill	F. Goodwill The Company allocates goodwill arising from business combinations to each cash-generating unit or group of cash-generating units that are expected to receive the benefits from the business combination. Irrespective of any indication of impairment, the recoverable amount of the cash-generating unit or group of cash-generating units to which goodwill has been allocated is tested annually for impairment and when there is an indication that the goodwill may be impaired. Any impairment is recognized as an expense immediately. Any impairment of goodwill is not subsequently reversed.
Mineral, Royalty and Other Interests	G. Mineral, Royalty and Other Interests Mineral, royalty and other interests consist of acquired royalty interests and stream metal purchase agreements. 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 agreement are expensed in the period incurred. Producing mineral, royalty and other interests are depleted using the units-of-production On acquisition of a mineral, royalty or other interest, an allocation of its cost is attributed to the exploration potential of the interest and is recorded as an asset on the acquisition date. The value of the exploration potential is accounted for in accordance with IFRS 6, Exploration and Evaluation of Mineral Resources 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.
Impairment of Mineral, Royalty and Other Interests	H. Impairment of Mineral, Royalty and Other Interests Evaluation of the carrying values of each mineral property is undertaken when events or changes in circumstances indicate that the carrying values may not be recoverable and at each reporting period. If any indication of impairment exists, the recoverable amount is estimated to determine the extent of any impairment loss. The recoverable amount is the higher of the fair value less costs of disposal and value in use. Fair value is the price that would be received from selling an asset in an orderly transaction between market participants at the measurement date. Costs of disposal are incremental costs directly attributable to the disposal of an asset. Fair value less costs of disposal is usually estimated using a discounted cash flow approach. Estimated future cash flows are calculated using estimated production, sales prices, and a discount rate. Estimated production is determined using current reserves and the portion of resources expected to be classified as mineral reserves as well as exploration potential expected to be converted into resources. Estimated sales prices are determined by reference to an average of long-term metal price forecasts by analysts and management’s expectations. The discount rate is estimated using an average discount rate incorporating analyst views to value precious metal royalty companies. Value in use is determined as the future value of present cash flows expected to be derived from continuing use of an asset in its present form for those assets where value in use exceeds fair value less costs of disposal. If it is determined that the recoverable amount is less than the carrying value, then an impairment is recognized within net income (loss) immediately. An assessment is made at each reporting period if there is any indication that a previous impairment loss may no longer exist or has decreased. If indications are present, the carrying amount of the mineral interest is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount net of depletion that would have been determined had no impairment loss been recognized for the mineral interest in previous periods.
Exploration Assets	I. Exploration Assets All costs incurred prior to obtaining the legal right to undertake exploration and evaluation activities on a project are expensed in the period incurred. Exploration and evaluation costs arising following the acquisition of an exploration license are capitalized on a project-by-project Upon demonstration of the technical and commercial feasibility of a project and a development decision, any past exploration and evaluation costs related to that project are subject to an impairment test and are reclassified in accordance with IAS 16, Property Plant and Equipment. Management assesses exploration assets for impairment at each reporting period or when facts and circumstances suggest that the carrying value of capitalized exploration costs may not be recoverable.
Revenue Recognition	J. Revenue Recognition Revenue is comprised of revenue earned in the period from contracts with customers under each of its royalty and mineral stream interests. The Company has determined that each unit of a commodity that is delivered to a customer under a royalty and mineral stream interest arrangement is a performance obligation for the delivery of a good that is separate from each other unit of the commodity to be delivered under the same arrangement. In accordance with IFRS 15, the Company recognizes revenue to depict the transfer 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 agreements, revenue recognition occurs when the relevant commodity received from the stream operator is transferred by the Company to its third-party customers. For royalty interests, revenue recognition occurs when 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.
Foreign Currency Translation	K. Foreign Currency Translation The functional currency of the Company and its subsidiaries is the principal currency of the economic environment in which they operate. For the Company and its subsidiaries Sandstorm Gold (Canada) Ltd., Bridgeport Gold Inc., Inversiones Mineras Australes S.A., Inversiones Mineras Australes Holdings (BVI) Inc., Premier Royalty U.S.A. Inc., SA Targeted Investing Corp., Sandstorm Metals & Energy (Canada) Holdings Ltd., Sandstorm Metals & Energy (Canada) Ltd., Sandstorm Metals & Energy (US) Inc., Mariana Resources Limited and Mariana Turkey Limited the functional currency is the U.S. dollar. The functional currency of the Company’s Hod Maden interest in associate is the Turkish Lira. To translate the Hod Maden interest to the presentation currency of the U.S. dollar, all assets and liabilities are translated using the exchange rate as of the reporting date and all income and expenses are translated using the average exchange rates during the period. All resulting exchange differences are recognized in other comprehensive income (loss). Transactions in foreign currencies are initially recorded in the entity’s functional currency as the rate on the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated using the closing rate as at the reporting date.
Financial Instruments	L. Financial Instruments The Company’s financial instruments consist of cash and cash equivalents, trade receivables and other, short and long-term investments, loans receivable which are included in other current assets, trade and other payables and bank debt. All financial instruments are initially recorded at fair value and designated as follows: Cash and cash equivalents, trade receivables and other, and loans receivable which are included in other current assets are classified as financial assets at amortized cost and trade and other payables and bank debt are classified as financial liabilities at amortized cost. Both financial assets at amortized cost and financial liabilities at amortized cost are measured at amortized cost using the effective interest method. The company’s financial assets which are subject to credit risk include cash and cash equivalents, trade receivables and other and loans receivable which are included in other current assets. Application of the expected credit loss model at the date of adoption did not have a significant impact on the Company’s financial assets because the Company determined that the expected credit losses on its financial assets were nominal. There were no impairment losses recognized on financial assets during the years ended December 31, 2019 and December 31, 2018. Investments in common shares are held for long-term strategic purposes and not for trading. The Company has made an irrevocable election to designate all these investments as fair value through other comprehensive income (“FVTOCI”) in order to provide a more meaningful presentation based on management’s intention, rather than reflecting changes in fair value in net income. Such investments are measured at fair value at the end of each reporting period, with any gains or losses arising on re-measurement Investments in warrants and convertible debt instruments are classified as fair value through profit or loss (“FVTPL”). These warrants and convertible debt instruments are measured at fair value at the end of each reporting period, with any gains or losses arising on re-measurement Transaction costs on initial recognition of financial instruments classified as FVTPL are expensed as incurred. Transaction costs incurred on initial recognition of financial instruments classified as loans and receivables, FVTOCI and other financial liabilities are recognized at their fair value amount and offset against the related loans and receivables or capitalized when appropriate. Financial assets are derecognized when the contractual rights to the cash flows from the asset expire. Financial liabilities are derecognized only when the Company’s obligations are discharged, cancelled or they expire. On derecognition, the difference between the carrying amount (measured at the date of derecognition) and the consideration received (including any new asset obtained less any new liability obtained) is recognized in profit or loss.
Inventory	M. Inventory When refined gold or the applicable commodity, under the Stream agreement, is delivered to the Company, it is recorded as inventory. The amount recognized as inventory includes both the cash payment and the related depletion associated with the related mineral interest.
Cash and Cash Equivalents	N. Cash and Cash Equivalents Cash and cash equivalents include cash on account, demand deposits and money market investments with maturities from the date of acquisition of three months or less, which are readily convertible to known amounts of cash and are subject to insignificant changes in value.
Income Taxes	O. Income Taxes Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used are those that are substantively enacted at the reporting date. Deferred income taxes are provided using the liability method on temporary differences at the reporting date between the tax bases of assets and liabilities and their carrying amounts for accounting. The change in the net deferred income tax asset or liability is included in income except for deferred income tax relating to equity items which is recognized directly in equity, and relating to investments in common shares designed as FVTOCI which is recognized in other comprehensive income. The income tax effects of differences in the periods when revenue and expenses are recognized in accordance with Company accounting practices, and the periods they are recognized for income tax purposes are reflected as deferred income tax assets or liabilities. Deferred income tax assets and liabilities are measured using the substantively enacted statutory income tax rates which are expected to apply to taxable income in the years in which the assets are realized or the liabilities settled. 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 for utilization. Deferred income tax assets and liabilities are offset only if a legally enforceable right exists to offset current tax assets against liabilities and the deferred tax assets and liabilities relate to income taxes levied by the same taxation authority on the same taxable entity and are intended to be settled on a net basis. The determination of current and deferred taxes requires interpretations of tax legislation, estimates of expected timing of reversal of deferred tax assets and liabilities, and estimates of future earnings.
Share Capital and Share Purchase Warrants	P. Share Capital and Share Purchase Warrants The proceeds from the issue of units are allocated between common shares and share purchase warrants (with an exercise price denominated in U.S. dollars) on a pro-rata
Earnings Per Share	Q. Earnings Per Share Basic earnings per share is computed by dividing the net income available to common shareholders by the weighted average number of common shares issued and outstanding during the period. Diluted earnings per share is calculated assuming that outstanding share options and share purchase warrants, with an average market price that exceeds the average exercise prices of the options and warrants for the year, are exercised and the proceeds are used to repurchase shares of the Company at the average market price of the common shares for the year.
Share Based Payments	R. Share Based Payments The Company recognizes share based compensation expense for all share purchase options and restricted share rights (“RSRs”) awarded to employees, officers and directors based on the fair values of the share purchase options and RSRs at the date of grant. The fair values of share purchase options and RSRs at the date of grant are expensed over the vesting periods of the share purchase options and RSRs, respectively, with a corresponding increase to equity. The fair value of share purchase options is determined using the BSM with market related inputs as of the date of grant. Share purchase options with graded vesting schedules are accounted for as separate grants with different vesting periods and fair values. The fair value of RSRs is the market value of the underlying shares at the date of grant. At the end of each reporting period, the Company re-assesses The BSM requires management to estimate the expected volatility and expected term of the equity instrument, the risk-free rate of return over the term, expected dividends, and the number of equity instruments expected to ultimately vest. The Company uses its competitors market data with respect to expected volatility and expected dividend yield to the extent these factors are indicative of the Company’s future expectations. The expected term is estimated using historical exercise data, and the number of equity instruments expected to vest is estimated using historical forfeiture data.
Related Party Transactions	S. 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.
Segment Reporting	T. Segment Reporting An operating segment is a component of the Company that engages in business activities from which it may earn revenues and incur expenses. The Company’s operating segments are components of the Company’s business for which discrete financial information is available and which are reviewed regularly by the Company’s Chief Executive Officer to make decisions about resources to be allocated to the segment and assess its performance.
Leases	U. Leases Upon lease commencement, the Company recognizes a right-of-use right-of-use re-measured
