The Company has consistently applied the following accounting policies to all periods presented in these financial statements.

These financial statements include the accounts of the Company. All significant intercompany transactions, balances, revenues, and expenses have been eliminated upon consolidation.

Subsidiaries are included in the consolidated financial results of the Company from the effective date of acquisition or control and up to the effective date of disposition or loss of control. Control is achieved when the Company has power over the investee, is exposed to or has rights to variable returns from its involvement with an investee, and had the ability to affect those returns through its power over the investee.

Fortuna Silver Mines Inc. is the ultimate parent entity of the group. At December 31, 2023, the principal subsidiaries of the Company, their geographic locations, and the ownership interests held by the Company, were as follows:



Name	Location	Ownership	Principal Activity
Minera Bateas S.A.C. ("Bateas")	Peru	100%	Caylloma Mine
Compania Minera Cuzcatlan S.A. de C.V. ("Cuzcatlan")	Mexico	100%	San Jose Mine
Mansfield Minera S.A. ("Mansfield")	Argentina	100%	Lindero Mine
Roxgold SANU S.A. (“Sanu”)	Burkina Faso	90%	Yaramoko Mine
Roxgold SANGO S.A. (“Sango”)	Côte d’Ivoire	90%	Séguéla Mine

A business combination is an acquisition of assets and liabilities that constitute a business. A business is an integrated set of activities and assets that consist of inputs and processes, including operational processes that, when applied to those inputs, have the ability to create outputs that provide a return to the Company and its shareholders. A business also includes those assets and liabilities that do not necessarily have all the inputs and processes required to produce outputs, but can be integrated with the inputs and processes of the Company to create outputs.

When acquiring a set of activities or assets in the exploration and development stage, which may not have outputs, the Company considers other factors to determine whether the set of activities or assets is a business.

Acquisitions of businesses are accounted for using the acquisition method. The consideration transferred in a business combination is measured at fair value, which is allocated to the identifiable assets acquired and liabilities assumed based on the acquisition-date fair value. The excess of the cost of acquisition over the fair value of the Company’s share of the identifiable net assets acquired is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets acquired, the difference, or gain, is recognized directly in the consolidated statement of operations. The results of businesses acquired during the period are included in the financial statements from the date of acquisition. Acquisition-related costs are expensed as incurred. Provisional fair values are finalized within 12 months of the acquisition date. Measurement period adjustments are adjustments that arise from additional information obtained during the measurement period about facts and circumstances that existed at the acquisition date.

Non-controlling interests represents equity interests in subsidiaries owned by outside parties. Non-controlling interests are recorded at their proportionate share of the fair value of identifiable net assets acquired on initial recognition. The share of net assets of subsidiaries attributable to non-controlling interests is presented as a component of equity. Their share of net income and other comprehensive income is recognized directly in equity even if the results of the non-controlling interest have a deficit balance.

The Company recognizes transactions with non-controlling interest as transactions with equity shareholders. Changes in the Company’s ownership interest in subsidiaries that do not result in loss of control are accounted for as equity transactions.

These financial statements are presented in United States Dollars (“$” or “US$” or “US dollars”), which is the functional currency of the Company. Reference to C$ are to Canadian dollars. All amounts in these financial statements have been rounded to the nearest thousand US dollars, unless otherwise stated.

The functional currency for each entity consolidated within the Company's financial statements is determined by the currency of the primary economic environment in which it operates. The functional currency of all subsidiaries is US dollars except for those outlined in the table below.



Name of Subsidiary	Place of Incorporation	Beneficial Common Share Ownership Interest	Principal Activity	Functional Currency
Roxgold Inc.	Canada	100%	Holding	CAD
FR Gold Mining Inc.	Canada	100%	Holding	CAD
Fortuna Silver Mines Australia Pty Ltd.	Australia	100%	Corporate	AUD
LGL Exploration Côte d’Ivoire SA	Côte d’Ivoire	100%	Exploration	XOF
LGL Resources Côte d’Ivoire SA	Côte d’Ivoire	100%	Exploration	XOF

Assets and liabilities of the subsidiaries that have a functional currency other than US dollar are translated into US dollars at the exchange rate in effect on the consolidated statements of financial position date and revenues and expenses are translated at the average rate over the reporting period. Gains and losses from these translations are recognized in other comprehensive income.

Transactions in foreign currencies are initially recorded in the functional currency at the exchange rate at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated at the rate of exchange at each financial position date. Foreign exchange gains or losses on translation to the functional currency of an entity are recorded in profit or loss. Non-monetary items that are measured in terms of historical cost in a foreign currency are translated using the exchange rate as at the date of the initial transaction.

Inventories include mineral concentrates, doré, leach pad, gold in-circuit, stockpiled ore, materials and supplies, which are valued at the lower of average production cost and estimated net realizable value. Production costs allocated to metal inventories include direct mining costs, direct labour costs, direct material costs, mine site overhead, depletion and amortization. Stockpiled ore that is not expected to be processed within the next twelve months is classified as non-current. Costs allocated to materials and supplies are based on weighted average costs and include all costs of purchase and other costs in bringing these inventories to their existing location and condition.

In the heap leaching process, ore is stacked on the leach pad and treated with a chemical solution that dissolves the gold contained within the ore. The resulting pregnant solution is further processed in a plant where the gold is recovered. The cost of leach pad inventory is based on cost of mining, crushing, and leaching, including applicable depletion and amortization, and is removed as ounces of gold are recovered at the weighted average cost per recoverable ounce of gold on the leach pad. Estimates of recoverable gold in the leach pad are calculated based on the quantities of ore placed on the leach pad (measured tonnes added to the leach pad), the estimated grade of ore placed on the leach pad (based on assay data), and an estimated recovery percentage (based on estimated recovery assumptions from metallurgical testing). The nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, estimates are refined based on actual results and engineering studies over a

period of time. The final recovery of gold from leach pad will not be known until the leaching process is concluded at the end of the mine life.

If the carrying value exceeds the net realizable amount, a write-down is recognized. The write-down may be reversed in a subsequent period if the circumstances which caused the write-down no longer exist, to the extent that the related inventory has not been sold. Net realizable value is calculated as the estimated price at the time of sale based on prevailing metal prices less estimated future costs to convert the inventories into saleable form and estimated costs to sell.

Exploration expenditures on properties for which the Company does not have title or rights to are expensed when incurred. Significant payments related to the acquisition of land and mineral rights and the costs to conduct a preliminary evaluation to determine that the property has potential to develop an economic ore body are capitalized as incurred. The time between initial acquisition and a full evaluation of a property’s potential is dependent on many factors including, but not limited to, location relative to existing infrastructure, the property’s stage of development, geological controls and metal prices.

The Company capitalizes the cost of acquiring, maintaining its interest, and exploring mineral properties as exploration and evaluation assets until such time as the properties are placed into development, abandoned, sold, or considered to be impaired in value.

If a mineable ore body is discovered, exploration and evaluation costs are reclassified to mining properties. The Company uses the following criteria in its assessment:

Exploration and evaluation assets are tested for impairment when an indicator of impairment is identified and upon reclassification to mining properties.

If no mineable ore body is discovered, all previously capitalized costs are expensed in the period in which it is determined the property has no economic value.

Proceeds received from the sale of interests in exploration and evaluation assets are credited to the carrying value of the mineral properties, plant and equipment. Exploration costs that do not relate to any specific property are expensed as incurred.

For operating mines, all mineral property expenditures are capitalized and amortized based on a unit-of-production method considering the expected production to be obtained over the life of the mineral property. The expected production includes proven and probable reserves, and for the Caylloma, Yaramoko, and Séguéla mines the portion of inferred resources expected to be extracted economically as part of the production cost.

Capitalized costs of producing properties are amortized on a unit-of-production basis over proven and probable reserves and the portion of inferred resources where it is considered highly probable that those resources are expected to be extracted economically.

The expected production to be obtained over the life of the mineral property is based on our life-of-mine production plans which for Caylloma, Yaramoko and Séguéla include a portion of inferred resources, and therefore differ from the life-of-mine plans the Company publishes as part of our NI 43-101 compliant technical reports which are based on reserves only. The decision to use inferred resources, and the portion of inferred resources to be included varies for each operation and is based on the geological characteristics of the ore body, the quality and predictability of inferred resources, and the conversion of inferred resources into measured and indicated (“M&I”) that the Company has historically achieved in the past.

As part of the process to include inferred resources into our life-of-mine production plans, the Company applies an economic cut-off to identify only the material that can be considered profitable to mine within our mine designs, and at this time we apply a conversion or “risk” factor to the mining blocks comprised of inferred resources that we include in such mine production plans. This conversion factor is based on the predictability of conversion derived from statistical estimates of confidence as described above and the support from historic conversion rates of inferred resources into M&I at each of our mines. The conversion factors used in our 2023 life-of-mine plans were 0% (2022: 90%) at San Jose, 90% (2022: 90%) at Caylloma, 100% (2022: 100%) at Yaramoko, and 100% at Séguéla.

The percentage of inferred resources included as a component of the total mineable inventory (reserve and resource) considered in the 2023 life-of-mine evaluation for each operation as of December 31, 2023, was San Jose 0% (2022: 31%), Caylloma 50% (2022: 41%), Yaramoko 5% (2022: 8%), Séguéla 1%, and Lindero 0% (2022: 0%).

The Company reviews the conversion factors including past experience in assessing the future expected conversion of inferred resources to be used in the life-of-mine plans for inclusion of inferred resources once a year in light of new geologic information and conversion data and when events or circumstances indicate that a review should be made. The Company continually monitors expected conversion and any changes in estimates that arise from this review are accounted for prospectively.

Property, plant and equipment are recorded at cost, net of accumulated depreciation and impairments. Costs directly related to construction projects are capitalized to work in progress until the asset is available for use in the manner intended by management. Assets, other than capital works in progress, are depreciated to their residual values over their estimated useful lives as follows:




Land and buildings
Land	Not depreciated
Mineral properties	Units of production	Declining balance
Buildings, located at the mine	Units of production	Declining balance
Buildings, others ⁽¹⁾	6-10 years	Straight line
Leasehold improvements ⁽¹⁾	4-8 years	Straight line
Plant and equipment
Processing plant	Units of production	Declining balance
Machinery and equipment ⁽¹⁾	3-12 years	Straight line
Furniture and other equipment ⁽¹⁾	2-12 years	Straight line
Transport units	4-5 years	Straight line
Capital work in progress	Not depreciated

Equipment under finance lease is initially recorded at the present value of minimum lease payments at the inception of the lease and depreciated over the shorter of the lease term or useful life.

Spare parts and components included in machinery and equipment are depreciated over the shorter of the useful life of the component or the related machinery and equipment.

Borrowing costs attributed to the construction of qualifying assets are capitalized to mineral properties, plant and equipment, and are included in the carrying amounts of related assets until the asset is available for use in the manner intended by management.

The sales proceeds and associated production costs incurred during commissioning of qualifying assets under capital works in progress are recognized in profit or loss.

On an annual basis, the depreciation method, useful economic life, and residual value of each component asset is reviewed with any changes recognized prospectively over its remaining useful economic life.

Pre-production stripping costs are generally capitalized and amortized over the production life of the mine using the unit-of-production method.

Stripping costs incurred during the production stage are incurred in order to produce inventory or to improve access to ore which will be mined in the future. Where the costs are incurred to produce inventory, the production stripping costs are accounted for as a cost of producing those inventories. Where the costs are incurred to improve access to ore which will be mined in the future, the costs are deferred and capitalized to the statement of financial position as a stripping activity asset (included in mining interest) if the following criteria are met:

If these criteria are not met, the costs are expensed in the period in which they are incurred.

The stripping activity asset is subsequently depleted using the units-of-production depletion method over the life of the identified component of the ore body to which access has been improved as a result of the stripping activity.

At the end of each reporting period, the Company assesses for impairment indicators and if there are such indicators, then the Company performs a test of impairment.

For the purpose of assessing impairment, assets are grouped at the lowest level for which there are separately identifiable cash inflows or cash generating units. These are typically individual mines or development projects. Brownfields exploration projects, located close to existing mine infrastructure, are assessed for impairment as part of the associated mine cash generating unit.

An impairment loss is recognized for the amount by which the asset’s carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset’s fair value less cost of disposal (“FVLCD”) and value in use.

When the recoverable amount is assessed using discounted cash flow techniques, the resulting estimates are based on detailed mine and/or production plans. For value in use, recent cost levels are considered, together with expected changes in costs compatible with the current condition of the business. The cash flow forecasts are based on best estimates of the expected future revenues and costs, including the future cash costs of production, sustaining capital expenditures, and reclamation and closure costs.

Where a FVLCD model is used, the cash flow forecast includes net cash flows expected to be realized from extraction, processing, and sale of mineral resources that do not currently qualify for inclusion in proven or probable reserves and the portion of resources expected to be extracted economically.

Where an impairment loss subsequently reverses, the carrying amount of the asset or cash-generating unit is increased to the revised estimate of recoverable amount but not beyond the carrying amount, net of depreciation and amortization, that would have been determined had no impairment loss been recognized for the asset or cash-generating unit in prior years. A reversal of an impairment loss is recognized into earnings immediately.

Interest and other financing costs incurred that are attributable to acquiring and developing exploration and development stage mining properties and constructing new facilities (“qualifying assets”), are capitalized and included in the carrying amounts of qualifying assets until those qualifying assets are capable of operating in the manner intended by management.

The capitalization of borrowing costs incurred commences on the date when the following three conditions are met:

Borrowing costs incurred after the qualifying assets are substantially complete are expensed.

Transaction costs, including legal, upfront commitment fees and other costs of issuance, associated with debt are recorded against the debt and are amortized over the term of the credit facility using the effective interest rate method.

All other borrowing costs are expensed in the period in which they are incurred.

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

Deferred tax assets and liabilities are recognized for deferred tax consequences attributable to unused tax loss carry forwards, unused tax credits, and differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis (“temporary differences”). Deferred tax assets and liabilities are measured using the enacted or substantively enacted tax rates expected to apply when the asset is realized, or the liability is settled.

The effect on deferred tax assets and liabilities of a change in tax rates is recognized in profit or loss in the period that substantive enactment occurs.

A deferred tax asset is recognized to the extent that it is probable that future taxable income 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.

The following temporary differences do not result in deferred tax assets or liabilities:

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.

Future obligations to retire an asset, including dismantling, remediation and ongoing treatment and monitoring of the site related to normal operation are initially recognized and recorded as a liability based on estimated future cash flows discounted at the risk-free rate.

The closure and reclamation provision (“CRP”) is adjusted at each reporting period for changes to the expected amount of cash flows required to discharge the liability, the timing of such cash flows and the risk-free discount rate.

The liability is accreted to full value over time through periodic charges to profit or loss.

The amount of the CRP initially recognized is capitalized as part of the related asset’s carrying value and amortized to profit or loss. The method of amortization follows that of the underlying asset. The costs related to a CRP are only capitalized to the extent that the amount meets the definition of an asset and can bring about future economic benefit. For a closed site or where the asset which generated a CRP no longer exists, there is no longer a future benefit related to the costs and as such, the amounts are expensed. Revisions in estimates or new disturbances

result in an adjustment to the CRP with an offsetting adjustment to the asset, unless there is no future benefit, in which case they are expensed.

Due to uncertainties inherent in environmental remediation, the ultimate cost of future site closure and reclamation could differ from the amounts provided. The estimate of future site closure and reclamation costs is subject to change based on amendments to laws and regulations, changes in technologies, price increases and changes in interest rates, and as new information concerning the Company’s closure and reclamation obligations becomes available. Such changes are reflected prospectively in the determination of the provision.

During the operating life of an asset, events such as infractions of environmental laws or regulations may occur. These events are not related to the normal operation of the asset and are referred to as environmental disturbance restoration provisions (“EDRP”). The costs associated with an EDRP are accrued and charged to earnings in the period in which the event giving rise to the liability occurs. Any subsequent adjustments to an EDRP due to changes in estimates are also charged to earnings in the period of adjustment. These costs are not capitalized as part of the long-lived asset’s carrying value.

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 were not satisfied, the expense previously recognized is reversed in the period the forfeiture occurs.

Share-based payment expenses relating to cash-settled awards, including deferred share units, restricted share units, and performance share units, are accrued and expensed over the vesting period based on the quoted market value of the Company’s common shares. As these awards will be settled in cash, the expense and liability are adjusted at each reporting period for any changes in the underlying share price.

Equity settled share-based payment transactions with parties other than employees are measured at the fair value of the goods or services received, except where that fair value cannot be estimated reliably, in which case they are measured at the fair value of the equity instruments granted, measured at the date the Company obtains the goods or the counter party renders the services.

The Company applies the fair value method of accounting for all stock option awards. Under this method, the Company recognizes a compensation expense for all stock options awarded to employees, based on the fair value of the options on the date of grant which is determined by using the Black-Scholes option pricing model. The fair value of the options is expensed over the graded vesting period of the options.

Deferred share units (“DSU”) are typically granted to non-executive directors of the Company. They are payable in cash upon resignation, retirement, removal, failure to achieve re-election, or upon a change of control of the Company. The DSU compensation liability is accounted for based on the number of DSUs outstanding and the quoted

market value of the Company’s common shares at the financial position date. The year-over-year change in the DSU compensation liability is recognized in profit or loss.

The Company’s share unit plan covers all restricted share units (“RSUs”) and performance share units (“PSUs”) granted by the Company.

The Company’s RSUs are settled in either cash or equity, as determined by the Company’s Board of Directors at the grant date and typically vest over three years.

For cash settled RSUs, the share-based payment expense is adjusted at each reporting period to reflect any change in the quoted market price of the Company’s common shares and the vesting of each RSU grant, with a corresponding amount recorded in Trade and Other Payables, and Other Non-Current Liabilities.

For equity-settled RSUs, the fair value is determined based on the quoted market price of the Company’s common shares at the date of grant, and the fair value is recognized as a share-based payment expense over the vesting period with a corresponding amount recorded in equity reserves.

The Company’s PSUs are performance-based awards for the achievement of specified performance metrics by specified deadlines and are settled in either cash or equity, as determined by the Company’s Board of Directors at the grant date and typically vest over three years.

For cash settled PSUs, the share-based payment expense is adjusted at each reporting period to reflect any change in the quoted market price of the Company’s common shares, the vesting of each PSU grant and the expected performance factors with a corresponding amount recorded in Trade and Other Payables.

For equity-settled PSUs, the fair value is determined based on the quoted market price of the Company’s common shares at the date of grant and the number of PSUs expected to vest based on the performance factors. The fair value is recognized as a share-based payment expense over the vesting period with a corresponding amount recorded in equity reserves.

Financial assets are measured as either: amortized cost; fair value through other comprehensive income (“FVOCI”) or fair value through profit or loss (“FVTPL”). All non-derivative financial liabilities are measured at amortized cost. The classification of financial assets is generally based on the business model in which a financial asset is managed and its contractual cash flow characteristics. Derivatives embedded in contracts where the host is a financial asset in the scope of the standard are never separated, and instead the hybrid financial instrument is assessed for classification.

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as at FVTPL:

A debt investment is measured at FVOCI if it meets both of the following conditions and is not designated as at FVTPL:

On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment’s fair value in other comprehensive income (OCI). This election is made on an investment-by-investment basis. All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVTPL.

Components of compound financial instruments are separately classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument. The financial liability is initially recognized at fair value, net of an allocation of issuance costs, and is subsequently measured at amortized cost. The equity component is initially measured based on the residual amount, net of an allocation of issuance costs, and is not subsequently remeasured.

Equity instruments issued by the Company are recognized at the proceeds received, net of direct issue costs. Repurchase of the Company’s own equity instruments is recognized and deducted directly in equity. No gain or loss is recognized in profit or loss on the purchase, sale, or cancellation of our own equity instruments. No gain or loss is recognized on the issue of our own equity instruments, unless the equity is issued to settle a liability.

Financial Liabilities at Amortized Cost – Financial liabilities are measured at amortized cost using the effective interest method, unless they are required to be measured at fair value through profit or loss, or the Company has opted to measure them at FVTPL. Debt and accounts payable and accrued liabilities are recognized initially at fair value, net of any transaction costs incurred, and subsequently at amortized cost using the effective interest method.

The following accounting policies apply to the subsequent measurement of financial assets:

The Company earns revenue from contracts with customers related to its concentrate and doré sales. Revenue from contracts with customers is recognized when a customer obtains control of the concentrate or the doré and the Company satisfies its performance obligation. The Company considers the terms of the contract in determining the transaction price, which is the amount the entity expects to be entitled to in exchange for the transferring of the concentrates. The transaction price of a contract is allocated to each performance obligation based on its stand-alone selling price.

The Company satisfies its performance obligations for its concentrate sales based upon specified contract terms which are generally upon delivery to the customer at a specified warehouse or upon loading of the concentrate onto a vessel. The Company typically receives payment within one to four weeks of delivery.

Doré sales are recognized when the Company satisfies its performance obligation and control is transferred to the customer upon payment. Final weights and assays are adjusted on final settlement which is approximately one month after delivery.

Revenue from concentrate sales is recorded based upon forward market price of the expected final sales price date. IFRS 15 Revenue from Contracts with Customers (“IFRS 15”) does not consider provisional price adjustments associated with concentrate sales to be revenue from contracts with customers as they arise from changes in market pricing for silver, gold, lead and zinc between the delivery date and settlement date. As such, the provisional price adjustments are accounted for as derivatives and presented separately in Note 20 of these financial statements.

The Company adopted Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2) from January 1, 2023. The amendments require the disclosure of 'material', rather than 'significant', accounting policies. Although the amendments did not result in any changes to the accounting policies themselves, they impacted the accounting policy information disclosed in Note 3 in certain instances.

A number of new standards are effective for annual periods beginning on or after January 1, 2024 and earlier application is permitted; however, the Company has not early adopted any new or amended standards in preparing these financial statements. The Company is currently evaluating the impact of the following amended standard on its financial statements:

These amendments clarify that the classification of liabilities as current or non-current is based on the right to defer settlement in existence at the end of the reporting period, which is unaffected by management’s intentions or expectation. These amendments also introduce a definition of “settlement” to make clear that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets or services.

In addition, the amendments specify that only covenants that a company is required to comply with on or before the reporting date affect the company’s right to defer settlement of a liability, and therefore the classification of current or non-current. Such covenants affect whether the right exists at the end of the reporting period, even if compliance with the covenant is assessed only after the reporting date.

The amendments are applied retrospectively for annual periods beginning on or after 1 January 2024, with early application permitted.

The following new standards or amendments are effective for annual periods beginning on or after January 1, 2024 and are expected to have no impact on the Company’s financial statements:

The Company is currently evaluating the impact of the following amended standard, effective January 1, 2025, and interpretations on its consolidated financial statements:
