In the fourth quarter of 2023, mined material totaled 409,293 tonnes of ore, averaging 3.34 g/t Au, and

containing an estimated 43,913 ounces of gold from the Antenna pit. Movement of waste during the

quarter totaled 2,110,209 tonnes from Antenna and 104,472 tonnes from the Ancien pit, for a strip ratio

of 5.4:1.

In the fourth quarter of 2023, Séguéla produced 43,096 ounces of gold at an average head grade of

3.62 g/t Au, a 37 percent increase and a 5 percent decrease, respectively, compared to the previous

quarter. The increase in gold production is directly related to the mill achieving consistently higher

throughput, processing 387,624 tonnes, a 25 percent increase over the previous quarter.

Mine reconciliation to reserve model

Reconciliation of tonnes, grade , and gold ounces mined for the fourth quarter from Antenna show a

positive correlation when compared to the long -term reserve model with 6 percent higher ore tonnes

mined at 16 percent higher grades resulting in 24 percent more gold ounces extracted than predicted in

the model.

Processing

Process plant performance continued to improve as feed characteristics were stabilized and initial

bottlenecks addressed. Recovery in the fourth quarter increased to 94.9 %, ahead of feasibility study

assumptions. Plant productivity also continued to improve with throughput in the fourth quarter being

186 t/hr, a 20 percent increase on the 154 t/hr nameplate capacity.

Yaramoko Mine, Burkina Faso

Strong performance, achieves higher end of annual production guidance

Based on Yaramoko’s strong performance during the year, management increased guidance in the third

quarter of 2023 from 96 to 102 thousand ounces of gold to 110 to 120 thousand ounces of gold (refer to

Fortuna news release dated October 5, 2023).

In the fourth quarter of 2023, Yaramoko produced 28,235 ounces of gold at an average head grade of

7.16 g/t Au, a 17 and 7 percent decrease, respectively, compared to the previous quarter . Reduced

production was due to lower mill throughput in the fourth quarter, the depletion of low-grade stockpiles,

and a planned maintenance shutdown in December.

Exploration and grade control drilling success in conjunction with underground development extended

mineralization on the western side of the Zone 55 mineralized structure. This provided additional mining

areas which demonstrated wider and higher-grade extensions of mineralization within and beyond the

existing resource boundary.

• FY 2023 production: 4,656,631 ounces of silver, and 28,559 ounces of gold

During the fourth quarter of 2023, t he San Jose Mine produced 1.02 million ounces of silver , and

6,345 ounces of gold, a 25 and 23 percent decrease, respectively, with average head grades for silver and

gold of 145 g/t and 0.91 g/t, a 23 and 20 percent decrease, respectively, when compared to the previous

quarter.

The decrease in silver and gold production for the quarter is explained by the declining grade profile of

Mineral Reserves in the mine plan, as well as lower tonnage extracted from the mine. The reduction in

tonnage is due to operational challenges leading to delays in backfilling and blasting operations in stopes

P and Q during December 2023. During the fourth quarter, the processing plant milled 241,035 tonnes at

an average of 2,678 tonnes per day.

Production in 2023 totaled 4,656,631 ounces of silver and 28,559 ounces of gold , 12 percent and

16 percent below annual guidance range, respectively. The decrease in production is attributed primarily

to the 15-day illegal union blockade in the second quarter (refer to Fortuna news release dated May 2,

2023), the associated disruption to operations thereafter, and a silver and gold head grade reconciliation

to reserves at the lower end of guidance range.

Exploration continues at the newly discovered Yessi vein with encouraging results (refer to Fortuna news

release dated December 12, 2023).

2024 Guidance Outlook

Séguéla Mine, Côte d’Ivoire

Mill throughput expanded to 1.46 Mta, achieving 70% of mill expansion scheduled for 2026

The 2024 mine plan considers mining in the Antenna, Ancien , and Koula pits, with plans to process

1.46 million tonnes of ore averaging 3.0 g/t Au, and capital investments estimated at $ 39.8 million,

including $32 million for sustaining capital expenditures and $7. 8 million for Brownfields exploration

programs.

Feasibility and optimization work is underway to realize the opportunity to incorporate underground

mineable resources at the Sunbird, Ancien, and Koula deposits.

Major sustaining capital investments include:

• Capitalized stripping $17.1 million

• Tailings storage facility (TSF) lift $4.8 million

• Other miscellaneous $10.1 million

- 8 -

Capitalized stripping at Séguéla corresponds to further mining of the Antenna pit and development and

mining of the Ancien and Koula pits. The overall stripping ratio for 2024 is planned to be 8.2:1 . AISC for

2024 reflects the ongoing TSF expansion project, which will add tailings holding capacity for the next

two years and is expected to be completed in the first half of 2024.

In 2024, annual ore processing is expanded to 1.46 million tonnes, 17 percent above tonnage scheduled

for year 1 in the 2021 Technical Report, and close to the expansion target of 1.57 million tonnes scheduled

for year 3. Process plant de -bottlenecking initiatives in 2024 still present upside opportunities for

throughput capacity.

Cash cost and AISC:

• The Company expects a 2024 cash cost between $630 and $730 per ounce of gold, an increase of

approximately 113 percent over 2023 at the upper range, and 84 percent at the lower range of

guidance. The increase is mainly due to the mine’s stripping ratio rising from 3.7:1 to 8.2:1, in

accordance with the mine plan. In addition, higher costs are anticipated for processing, which

include milling, energy consumption, freight, transportation, and overhead.

• The Company expects a 2024 AISC between $1,110 and $1,230 per ounce of gold, an increase of

approximately 54 percent over 2023 at the upper range, and 39 percent at the lower range of

guidance. The increase is explained by higher cash cost per ounce and higher capex per ounce of

approximately $120 related to capitalized stripping costs.

Yaramoko Mine, Burkina Faso

Grade and tonnages benefit from exploration success in 2023

At the Yaramoko Mine, the Company plans to process 435,000 tonnes of ore averaging 8.3 g/t Au. Capital

investment decreases substantially compared to previous years and in 2024 mainly comprises of

development and exploration activities.

Major sustaining capital investment projects include:

• Mine development $13.9 million

• Brownfields exploration $6.1 million

Cash cost and AISC:

• The Company expects a 2024 cash cost between $865 and $965 per ounce of gold, an increase of

approximately 29 percent over 2023 at the upper range, and 16 percent at the lower range of

guidance. The increase is due primarily to the reallocation of fixed mining costs from capex to

opex and lower processed ore.

• The Company expects a 2024 AISC between $1,220 and $1,320 per ounce of gold, a decrease of

approximately 7 percent under 2023 at the upper range, and 14 percent at the lower range of

guidance. The decrease is explained by lower capex year over year of approximately $250 per

ounce of gold.
