Fortuna Extends High Grade Gold Mineralization at Sunbird, Including 6.1 g/t Au over 18.9 meters, Séguéla Mine, Côte d’Ivoire
NEWS RELEASE
Fortuna Extends High Grade Gold Mineralization at Sunbird,
Including 6.1 g/t Au over 18.9 meters, Séguéla Mine, Côte d’Ivoire
Vancouver, British Columbia, February 12, 2026: Fortuna Mining Corp. (NYSE: FSM |
TSX: FVI) is pleased to report results from ongoing exploration drilling at the Sunbird deposit,
located at the Séguéla Mine in Côte d’Ivoire (see Figure 1). Recent drilling has successfully
extended mineralization at depth and expanded a second high grade mineralized shoot.
Paul Weedon, Senior Vice President of Exploration, commented, “Continued d rilling at
Sunbird confirms that high grade mineralization remains wide open at depth.” Mr. Weedon
added, “With five drill rigs currently focused on Sunbird, these results build on previously
announced high grade drill intercepts and further underpin the potential for resource growth.”

A further 22 drill holes, totaling 9,816 meters, have been completed at the Sunbird deposit
as part of the underground resource confidence infill and extension drilling program (see
Figure 2). All drill holes were completed after the June 30, 2025 data cut-off date used for
reporting the current Séguéla Mineral Resources and Mineral Reserve s (refer to Fortuna
news release dated January 20, 2026 ). Drilling focused on extending the lower shoot and
has successfully delineated high grade gold mineralization approximately 400 meters beyond
the existing Mineral Resource and Mineral Reserves envelopes, with results including 13.0
g/t Au over an estimated true width of 4.2 meters from 686 meters depth in drill hole
SGDD149. Infill drilling has also targeted the linkage between the upper and lower shoots,
returning results such as 4.1g/t Au over an estimated true width of 11.9 meters from 499
meters depth in SGRD2487.
Mineralization at the Sunbird deposit remains open at depth and along strike , with drilling
expected to continue throughout 2026.
Refer to Appendix 1 for full details of the drill holes and assay results for this drill program.

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 reverse circulation (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 a ir 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 percent representative sample for submission to the analytical laboratory.
The residual 87.5 percent 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 started with HQ sized diameter, before reducing to NQ diameter
diamond drill bits on intersecting fresh rock. 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 samples were transported by Company vehicle or commercial courier to either the ALS
Global preparation laboratory in Yamoussoukro, Cote d’Ivoire or the Bureau Veritas preparation and
analytical laboratory in Abidjan, Cote d’Ivoire. Sample pul ps prepared by ALS Global were then
transported via commercial courier to ALS’s facility in Ouagadougou, Burkina Faso. Routine gold
analysis using a 50-gram charge and fire assay with an atomic absorption finish was completed for all
samples at either ALS’ s Ouagadougou laboratory or Bureau Veritas’ laboratory in Abidjan. Samples
returning assays >10 ppm Au were reanalyzed using a 50 -gram charge and fire assay with a
gravimetric finish. Quality control procedures included the systematic insertion of blanks, duplicates
and sample standards into the sample stream. In addition, both ALS and Bureau Veritas laboratories
inserted their own quality control samples.
