and 17.9 g/t Au over 5.4m at Galgouli Prospect, Boussoura, Burkina Faso

Vancouver, September 7, 2021-- Fortuna Silver Mines Inc. (NYSE: FSM) (TSX: FVI) is pleased to announce

continued high-grade results from recent extension and scout drilling at its projects in Cote d’Ivoire and

Burkina Faso in West Africa.

Paul Weedon, Vice President of Exploration - West Africa, commented, "The exploration teams at Burkina

Faso and Cote d’Ivoire have continued to advance the exploration understanding of key structures and

controls on mineralization in both the Sunbird and Galgouli projects with excellent results highlighting the

potential for setting up several new targets and extensions to the known deposits at Séguéla and

mineralization at Boussoura.” Mr. Weedon continued, “The company is looking forward to the continued

growth from both projects as we head into the second half of the year, with Gabbro North and Sunbird

emphasising the potential of Séguéla, and the continuing success of scout drilling at Boussoura in

expanding the mineralized footprint.”

Séguéla gold Project, Cote d’Ivoire

Exploration activities at the Séguéla gold Project (see Figure 1) have continued to advance the high-grade

Koula deposit with step -out drilling intersecting a new zone of hanging wall mineralization as well as

infilling the extension of the high-grade Koula structure. The combined 7,115-meter, 24-hole Hanging Wall

(HW) and Main Zone program, which started in April 2021 is now completed. The significance of the

results, including 28.8 g/t gold over 7 meters (refer to the Appendix, drill hole SGRD1217) and 19.8 g/t gold

over 11 meters (refer to the Appendix, drill hole SGRD1209 and to Figure 2) and the proximity to the Stage

Two Pit Shell are being evaluated. Mineralization remains open at depth on the main Koula structure while

the hanging wall mineralization highlights the potential for additional structures at depth.

Depth extension drilling at Sunbird, as part of the recently completed 1,774 meter, 11-hole program which

started in May 2021, has extended the mineralized envelope . R esults including 17.2 g/t gold over

30 meters ( refer to the Appendix, drill hole SGDD089) and 3.2 g/t gold over 28 metres ( refer to the

Appendix, drill hole SGDD088) highlight the depth potential with the deepest drilling less than 200 meters

below surface (refer to Figure 3). In addition, Sunbird is demonstrating very similar structural and

lithological controls to those identified at the Koula and Ancien deposits. Mineralization remains open at

depth and along strike with more than 1 kilometer of mineralized strike drill tested to date.

Further high -grade results, including 23.0 g/t gold over 4 meters ( refer to the Appendix, drill hole

SGRC1236), have been returned from the 14 -hole, 2,070 -meter additional scout drilling program

completed in August at Gabbro North (refer to Figure 4), following up from previous high -grade results

intersected in the first scout drilling phase in the second quarter of 2021. Drilling only tested the southern

zone of known mineralization with mineralization now delineated along a 300-meter strike and where it

remains open along strike and at depth.

Boussoura, Burkina Faso

Exploration activities at Boussoura where a 47 -hole, 5,958-meter program since March 2021 has

continued to advance Fofora Main where infill and extension drilling has increased the confidence in the

structural controls of mineralization, with several additional high -grade intervals returned, including

9.9 g/t gold over 8 meters (refer to the Appendix, drill hole FFR272). Sc out drilling at the adjacent vein

corridors to the west continues to highlight the regional potential, with drilling on vein corridors VC4 and

VC5 intersecting extensive zones of alteration and associated quartz veining and mineralization.

Further south at Galgouli, a 12-hole, 3,419-meter program depth extension drilling on the central zone

testing the structural controls and concluded in July was successful in identifying extensions to the high-

grade shoots at depth with results including 17.9 g/t gold over 5.4 meters (refer to the Appendix, drill hole

GAL055). A 32-hole, 4,022-meter scout drilling program was also successful in identifying high -grade

mineralization approximately 1 kilometer to the south and south-east of the central Galgouli zone, testing

interpreted parallel structures (10.9 g/t gold over 2 meters; refer to the Appendix, drill hole RC098) and a

possible regional scale cross -structure (22 .2 g/t gold over 2 meters ; refer to the Appendix, drill hole

RC096). A total of 44 holes have been completed for a total of 7,444 meters since April 2021.

Quality Assurance & Quality Control (QA-QC)

All drilling data completed by the Company utilized the following procedures and methodologies. All

drilling was carried out under the supervision of the company’s personnel.

All RC drilling at Séguéla and Boussoura used a 5.25-inch face sampling pneumatic hammer with samples

collected into 60-liter plastic bags. Samples were kept dry by maintaining enough air pressure to exclude

groundwater inflow. If water ingress exceeded the air pressure, RC drilling was stopped, and dri lling

converted to diamond core tails. Once collected, RC samples were riffle split through a three-tier splitter
