Fortuna Silver Mines Inc. provided an update on its exploration program at the Seguela Mine in Cote d'Ivoire.

Since the discovery announcement made earlier this year; an additional 5,423-meter, 40-hole program was completed at Kingfisher.

Results defined continuous mineralization over more than 1-kilometer of strike and joined the previous central and northern lodes; Kingfisher's location, approximately 1-kilometer east of Sunbird; Kingfisher prospect long section - looking west; and At Badior Prospect: At Badior, an additional 2,727-meter, 30-hole program was completed during 2024; to infill and test depth extensions to previous high-grade intersections; to infill and testdepth extensions to previous high-grade intersection; and at depth; and at depth. At Ancien, an additional 3,255-meter, 11-hole infill drill program was completed during the second quarter of 2024 to further refine the controls on the high-grade mineralized shoots at depth. Séguéla Mine, Côte d?Ivoire: 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 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 drilling converted to diamond core tails. Once collected, RC samples were riffle split through a three-tier splitter to yield a 12.5% representative sample for submission to the analytical laboratory. The residual 87.5% samples were stored at the drill site until assay results were received and validated.

Coarse reject samples for all mineralized samples corresponding to significant intervals are retained and stored on-site at the Company-controlled core yard. All diamond drilling (DD) drill holes were drilled with HQ sized diamond drill bits. The core was logged, marked up for sampling using standard lengths of one meter or to a geological boundary.

Samples were then cut into equal halves using a diamond saw. One half of the core was left in the original core box and stored in a secure location at the Company core yard at the project site. The other half was sampled, catalogued, and placed into sealed bags and securely stored at the site until shipment.

All RC and DD core samples were shipped to ALS Laboratories? preparation laboratory in Yamoussoukro for preparation and then, via commercial courier, to ALS?s facility in Ouagadougou, Burkina Faso for finishing. Routine gold analysis using a 50-gram charge and fire assay with an atomic absorption finish was completed for all samples.

Quality control procedures included the systematic insertion of blanks, duplicates and sample standards into the sample stream. In addition, the ALS laboratory inserted its own quality control samples.
