DISCLOSURE REGARDING CONTROLS AND PROCEDURES

Disclosure Controls and Procedures.

Disclosure controls and procedures are defined in Rule 13a-15(e) and Rule 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as those controls and procedures designed to ensure that information required to be disclosed in the annual filings and interim filings and other reports filed or submitted by Fortuna Silver Mines Inc. (the “Company”) under the Exchange Act is duly recorded, processed, summarized and reported, within the time periods specified in rules and forms of the United States Securities and Exchange Commission (the “SEC”). Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the Company’s reports and filings is accumulated and communicated to management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) as appropriate, to allow timely decisions regarding required disclosure.

The Company evaluated, with the participation of its CEO and CFO, the effectiveness of its disclosure controls and procedures as of December 31, 2017. Based on that evaluation, the CEO and the CFO have concluded that, as of the end of the period covered by this annual report on Form 40-F, the disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in the Company’s annual filings and interim filings and other reports filed or submitted under the Exchange Act, is recorded, processed, summarized and reported within time periods specified in SEC rules and forms and is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Notwithstanding the foregoing, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that the Company’s disclosure controls and procedures will detect or uncover every situation involving the failure of persons within the Company and its subsidiaries to disclose material information otherwise required to be set forth in the Company’s periodic reports. The Company’s disclosure controls and procedures are designed to provide reasonable assurance of achieving their objective of ensuring that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is communicated to management to allow timely decisions regarding required disclosure.

Management’s Annual Report on Internal Control Over Financial Reporting.

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as such term is defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) and has designed such internal controls over financial reporting to provide reasonable assurance regarding the reliability of financial reporting and preparation of financial statements for external purposes in accordance with International Financial Reporting Standards, as issued by the International Accounting Standards Board.

In designing and evaluating the Company’s internal control over financial reporting, the Company’s management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its reasonable judgment in evaluating the cost-benefit relationship of possible controls and procedures. Because of its inherent limitations, internal controls over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risks that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management of the Company, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer, had conducted as evaluation of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2016, using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on the evaluation performed, management concluded that material weaknesses existed as of December 31, 2016. Management subsequently took actions to address the material weaknesses, including (i) hiring a Vice-President of Finance and Accounting, an Internal Controls Manager, a Corporate Tax Manager, and local internal controls analysts at each of its operations; (ii) engaging external specialists to assist in the documentation and review of its internal controls; (iii) completing a fraud risk assessment; and (iv) redesigning general information technology controls over user access privileges, unauthorized access, and segregation of duties.

Following these remediation activities, management assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2017. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control - Integrated Framework (2013). Based on this assessment, management concluded that, as of December 31, 2017, the Company’s internal control over financial reporting was effective based on those criteria.

See “Management’s Report on Internal Control Over Financial Reporting” in the Management’s Discussion and Analysis for the fiscal years ended December 31, 2017 and 2016, included as Exhibit 99.3 to this annual report on Form 40-F. The Company’s auditors have issued an attestation report on management’s assessment of the Company’s internal control over financial reporting. See “Attestation Report of the Registered Public Accounting Firm” below.

Changes in Internal Control Over Financial Reporting. During the fiscal year ended December 31, 2017, other than as described in “Management’s Annual Report on Internal Control over Financial Reporting” above in response to the material weaknesses identified at December 31, 2016, there were no changes in the Company’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
