Fortuna announces positive construction decision for its Séguéla gold Project

in Côte d’Ivoire

Vancouver, September 29, 2021 -- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to

announce that the Board of Directors of the company has made a decision to proceed with the

construction of an open pit mine at the Séguéla gold Project in Côte d’Ivoire. The company is ready to

immediately commence construction with long lead items procured, and development teams established

on the ground. In July 2021, Fortuna completed the acquisition of Roxgold Inc. which was advancing the

Séguéla Project (see Fortuna´s news release dated July 2, 2021, “ Fortuna and Roxgold complete

combination to create a global premier growth -oriented intermediate gold and silver producer ”). For

specific details on the Séguéla Project feasibility study, please refer to the technical report entitled “NI 43‐

101 Technical Report, Séguéla Project, Feasibility Study, Worodougou Region, Côte d’Ivoire ” dated May

26, 2021.

Jorge A. Ganoza, President and CEO of Fortuna , commented, “With a nine year mine life in reserves,

130,000 ounces of annual gold production in the initial six years, and compelling economics , Séguéla is

planned to become our fifth operating mine with first gold by mid-2023.” Mr. Ganoza added, “Fortuna is

in a solid financial position to fund the remaining $162 million initial capital investment and our teams in

West Africa are primed and ready to start.” Mr. Ganoza concluded, “Parallel to construction, the company

plans to continue with well funded drill programs to test multiple remaining targets on the Séguéla

property, where over the last 12 months, the exploration team has successfully delivered gold discoveries

at the Koula, Sunbird and Gabbro North prospects.”

Paul Criddle, COO - West Africa of Fortuna, commented, “The decision to commence construction of the

still growing Séguéla Project, marks an exciting milestone for the company.” Mr. Criddle continued, “The

team has further derisked the project by advancing detailed design and commencing procurement of long

lead items , including the SAG mill and the e xecution of critical path agreements including the EPC

agreement with Lycopodium for the processing plant. This has allowed Séguéla´s critical path to be

protected as well as managing the cost risk by locking in substantial components of the initial cap ex in

fixed price contracts. ” Mr. Criddle added, “B ulk earthworks contractors have been mobili zed and will

break ground at the plant site in October with the accommodation village expected to be completed in

November of 2021.”

The updated Séguéla Project total initial capital investment is $173.5 million. $11.5 million of this amount

has previously been approved by the Board for early works items. The anticipated construction schedule

is approximately 20 months, with ramp-up to name plate capacity expected in the third quarter of 2023.
