2023 Mineral Reserves and Mineral Resources

Notes:

1. Mineral Reserves and Mineral Resources are as defined by the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves.
2. Mineral Resources are exclusive of Mineral Reserves.
3. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
4. Factors that could materially affect the reported Mineral Resources or Mineral Reserves include changes in metal price and exchange rate assumptions; changes in local interpretations of mineralization; changes to assumed metallurgical recoveries, mining dilution and recovery; and assumptions as to the continued ability to access the site, retain mineral and surface rights titles, maintain environmental and other regulatory permits, and maintain the social license to operate.
5. Mineral Resources and Mineral Reserves are reported as of December 31, 2023.
6. Mineral Reserves for the Caylloma Mine are reported above NSR breakeven cut-off values based on underground mining methods including: mechanized (breasting) that represents 91 % of Mineral Reserves planned for mining at $89.78/t, mechanized (uppers) at $79.70/t, semi-mechanized at $93.27/t, sub-level stoping at $88.81/t, and a conventional method at $170/t; using assumed metal prices of $21/oz Ag, $1,600/oz Au, $2,000/t Pb, and $2,600/t Zn; metallurgical recovery rates of 82 or 85 % for Ag, 22 or 55 % for Au, 87 or 89 % for Pb and 89 % for Zn. Mining, processing, and administrative costs used to determine NSR cut-off values were estimated based on actual operating costs incurred from July 2022 through June 2023. Mining recovery is estimated to average 94 % with average mining dilution of 17 % depending on the mining methodology. Mineral Resources are reported at an NSR cut-off grade of $75/t for veins classified as wide (Animas, Animas NE, Nancy, and San Cristobal) and $135/t for veins classified as narrow (all other veins) based on the same parameters used for Mineral Reserves, and a 15 % upside in metal prices.
7. Mineral Reserves for the San Jose Mine are based on underground mining within optimized stope designs using an estimated NSR break-even cut-off grade of $96.54/t to $85.02/t equivalent to 154 to 132 g/t Ag Eq based on assumed metal prices of $23.90/oz Ag and $1,880/oz Au; estimated metallurgical recovery rates of 91 % for Ag and 90 % for Au and mining costs of $49.83/t (C&F) - $38.31/t (SLS); processing costs of $20.79/t; and other costs including distribution, general service costs of $25.92/t based on actual operating costs. Average mining recovery is estimated to 94 % (C&F) and 92 % (SLS) and average mining dilution 10 % (C&F) and 14 % (SLS). Mineral Resources are reported at a 130 g/t Ag Eq cut-off grade based on the same parameters used for Mineral Reserves.
8. Mineral Reserves for the Lindero Mine are reported based on open pit mining within a designed pit shell based on variable gold cut-off grades and gold recoveries by metallurgical type: Met type 1 cut-off 0.28 g/t Au, recovery 75.4 %; Met type 2 cut-off 0.27 g/t Au, recovery 78.2 %; Met type 3 cut-off 0.27 g/t Au, recovery 78.5 %; and Met type 4 cut-off 0.31 g/t Au, recovery 68.5 %. Mining recovery and mining dilution have been accounted for during block regularization to 10-meter x 10-meter x 8-meter size. The cut-off grades and pit designs are considered appropriate for long term gold prices of $1,600/oz, estimated base mining costs of $1.36 per tonne of material, total processing and G&A costs of $9.78 per tonne of ore, and refinery costs net of pay factor of $12.20 per ounce gold. Reported Proven Reserves include 8.3 Mt averaging 0.44 g/t Au of stockpiled material. Mineral Resources are reported within a conceptual pit shell above a 0.24 g/t Au cut-off grade based on the same parameters used for Mineral Reserves and a 15 % upside in metal prices. Mineral Resources for Arizaro are reported within a conceptual pit shell above a 0.26 g/t Au cut-off grade using the same gold price and costs as Lindero with an additional $0.52 per tonne of ore to account for haulage costs between the deposit and plant. A slope angle of 47° was used for defining the pit.
9. Mineral Reserves for the Yaramoko Mine are reported on a 100 % ownership basis at a cut-off grade of 1.57 g/t Au for the Zone 55 open pit, 0.86 g/t Au for the Zone 109 open pit, 4.5 g/t Au for Zone 55 underground, 3.8 g/t Au for Bagassi South QV Prime and Bagassi South underground based on an assumed gold price of $1,600/oz, metallurgical recovery rates of 96.8 %, underground mining costs of $154/t, processing cost of $28/t and G&A costs of $27/t, surface mining costs of $4.95/t, processing cost of $27/t, and G&A costs of $33/t. Underground average mining recovery is estimated at 90 % for Bagassi South QV Prime and Bagassi South underground, 93 % for Zone 55 SLS stopes, and 86 % for sill drift stopes. A mining dilution factor of 10 % has been applied for sill drift stopes, 0.7-meter and 0.4-meter dilution skin has been applied for sub-level stopes and shrinkage mining respectively. Surface mining recovery and mining dilution have been accounted for during block regularization to 5-meter x 5-meter x 5-meter size within an optimized pit shell and only Proven and Probable categories reported within the final pit designs. Yaramoko Mineral Resources are reported at a gold grade cut-off grade of 0.9 g/t Au for the Zone 55 open pit, 0.5 g/t Au for the Zone 109 open pit, and 2.7 g/t Au and 2.5 g/t Au for underground Zone 55 and Bagassi South respectively, based on an assumed gold price of $1,840/oz and the same costs, metallurgical recovery and constrained within an optimized pit shell.

Historical Mineral Resources

This estimate was prepared in accordance with the JORC Code; refer to the Scoping Study Report entitled "Diamba Sud Project, Senegal, prepared by Chesser Resources Limited ("Chesser") and published on March 15, 2022 and subsequently amended on October 27, 2022, and December 12, 2022.

Disclosure of the historical estimate in this news release is derived from the Diamba Sud Scoping Study completed in March 2022 by Chesser Resourced Ltd and updated in October and December 2022 and has been judged to be relevant and therefore suitable for disclosure, however, it should not be relied upon. Mineral Resources were reported within a $1,800/oz gold price pit shell and at a cut-off grade of 0.5 g/t Au. In the Company's view, there are no material differences between the confidence categories assigned under the 2012 Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves prepared by the Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Counsel of Australia, as amended (the "JORC Code") and the equivalent confidence categories in the Canadian Institute of Mining 2014 Definition Standards for Mineral Resources and Reserves. NI 43-101, defined below, reporting requirements do not allow for "Inferred Mineral Resources" to be added to other Mineral Resource categories and must be reported separately. The Inferred Resource category estimates above under the JORC Code were reported separately in each instance. There are numerous uncertainties inherent in the historical estimate, which is subject to all of the assumptions, parameters, and methods used to prepare such historical estimates. The historical estimate has been prepared in accordance with the requirements of the Joint Ore Reserves Committee of The Australasian Institute of Mining and Metallurgy, Australian Institute of Geoscientists and Minerals Council of Australia and does not comply with or fulfill the CIM Definition Standards on Mineral Resources and Mineral Reserves, as amended, adopted by the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM Definition Standards") as required by National Instrument 43-101 - Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators ("NI 43-101"), and may vary significantly from actual amounts, grade, and quality of minerals recovered from the property. There are no other more recent estimates. Fortuna has completed 101 diamond drillholes totaling 13,102 meters and 166 reverse circulation drillholes totaling 19,448 meters as part of an ongoing program to confirm the historical estimate with no material discrepancies identified to date. A detailed study of the drill results, technical data and economic parameters relating to the property, together with the preparation of an updated development plan, is required to be conducted in order to update these historical estimates, as a current Mineral Resource or Mineral Reserve. A qualified person has not done sufficient work to classify the historical estimates as current Mineral Resources or current Mineral Reserves and Fortuna is not treating the historical estimate as current Mineral Resources. Investors are cautioned not to place undue reliance on the historical estimates contained in this news release.

Diamba Sud Gold Project, Senegal

Fortuna plans to prepare a Mineral Resource estimate in accordance with the disclosure requirements of Canadian National Instrument 43-101 - Standards of Disclosure for Mineral Projects upon the completion of the current Brownfields exploration program that includes 42,700 meters of drilling, including extension and resource development, in addition to the testing and advancement of previously identified geochemistry anomalies (refer to Fortuna news release dated January 18, 2024). The program is expected to finish by the end of August 2024 with the updated evaluation planned for completion by the end of 2024.

Caylloma Mine, Peru

As of December 31, 2023, the Caylloma Mine has Proven and Probable Mineral Reserves of 2.3 Mt containing 6.1 Moz Ag, 10 koz Au, 64 kt Pb, and 93 kt Zn in addition to Inferred Resources of 4.5 Mt containing 14.4 Moz Ag, 63 koz Au, 110 kt Pb, and 162 kt Zn.

Year-over-year, Mineral Reserve tonnes decreased by 28 percent, while silver grade increased 2 percent to 83 g/t, lead grade increased 5 percent to 2.78 %, and zinc grade increased 4 percent to 4.04 %. Changes are due to mining related depletion of 544,000 tonnes, a decrease by 51,000 tonnes due to higher cut-off values related to increases in operating costs, a decrease of 188,000 tonnes as a result of changes in commercial terms and metal price, a decrease of 218,000 tonnes due to adjustments in the estimation parameters and geologic interpretation, and conversion of 23,000 tonnes of Inferred Resources to Mineral Reserves.

Measured and Indicated Resource tonnes, exclusive of Mineral Reserves, decreased by 37 percent year-over-year to 1.8 Mt with silver and lead grades increasing slightly by 9 and 1 percent, respectively, and zinc grades decreasing by 12 percent, due to an increase in cut-off value as a result of higher operating costs and the application of operational dilution based on mineable shape optimizer evaluation to remove isolated and narrow mineralized structures from the inventory.

Inferred Resource tonnes decreased by 10 percent year-over-year. Silver grades decreased 6 percent, whereas lead and zinc grades increased by 9 and 8 percent, respectively. The decrease in Inferred Mineral Resources is a result of an increase in cut-off values used for reporting Mineral Resources from $65/t to $75/t resulting in a decrease of 416,000 tonnes and adjustments in the geologic interpretation, changes in commercial terms, and sterilization of material associated with isolated or narrow mineralization resulting in a decrease of 929,000 tonnes, offset by the discovery of 900,000 tonnes through exploration drilling of the Animas and Animas NE veins.

The Brownfields exploration program budget for 2024 at Caylloma is $2.0 million, supporting field exploration, regional geophysics, and ongoing studies of the structural controls to mineralization on the Animas vein (refer to Fortuna news release dated January 18, 2024).

San Jose Mine, Mexico

As of December 31, 2023, the San Jose Mine has Proven and Probable Mineral Reserves of 0.7 Mt containing 3.7 Moz Ag and 23 koz Au, in addition to Inferred Resources of 1.0 Mt containing a further 4.9 Moz Ag and 35 koz Au.

Year-over-year, Mineral Reserves decreased 66 percent in terms of tonnes, while silver grade decreased 9 percent and gold grade decreased 16 percent after net changes of minus 1 Mt resulting from production-related depletion, and a further decrease of 0.4 Mt due to the application of higher cut-off grades as a result of significant cost increments related to the appreciation of the Mexican Peso, higher contractor costs for transportation, distribution, shotcrete, maintenance, and mining services, higher labor costs and new labor reform mandates, change from owner's mining fleet to contractor fleet for mine development, and higher costs in fuel, energy, materials, and consumables related to 2023 inflation.

Measured and Indicated Resource tonnes exclusive of Mineral Reserves increased by 15 percent year-over-year, while silver and gold grades increased 35 and 54 percent, respectively. The change is due to an increase in cut-off grade from 110 g/t to 130 g/t Ag Eq due to cost increases as detailed above combined with the upgrading of Inferred Resources to Indicated Resources in the Victoria mineralized zone. An evaluation is ongoing as to whether sufficient tonnage at a high enough grade is located in localized areas of the Victoria mineralized zone to cover development and infrastructure costs allowing conversion of Inferred Resources to Mineral Reserves and inclusion in the mine plan.

Year-over-year, Inferred Resources decreased 59 percent in terms of tonnes, with grades increasing for silver and gold by 25 percent. The net variation is due primarily to the increase in cut-off grade used for reporting, as described above, the upgrading of Inferred Resources to Indicated Resources through infill drilling of the Victoria mineralized zone and changes in the geologic interpretation and removal of isolated mineralization through the application of a mineable stope optimizer.

The Brownfields exploration program budget for 2024 at San Jose is $4.9 million, which includes 13,900 meters of diamond drilling, focused on testing and extending the Yessi vein as well as exploring additional targets within the mine area (refer to Fortuna news release dated January 18, 2024).

Lindero Mine, Argentina

As of December 31, 2023, the Lindero Mine has Proven and Probable Mineral Reserves of 71.5 Mt containing 1.3 Moz Au, in addition to Measured and Indicated Resources, exclusive of Mineral Reserves, of 30.5 Mt containing 412 koz Au, and Inferred Resources of 25.3 Mt containing 386 koz Au.

Since December 31, 2022, Mineral Reserve tonnes decreased by 10 percent, while gold grade remained relatively unchanged at 0.56 g/t Au. Changes are primarily due to mining related depletion and sterilization of 6.5 Mt of material containing 122 koz Au delivered to the heap leach pad in 2023 and an increase in the reporting cut-off grade due to higher operating costs resulting in a decrease of 2.3 Mt containing 21 koz Au.

Measured and Indicated Resource gold ounces, exclusive of Mineral Reserves, remained relatively unchanged year-over-year.

Inferred Resource tonnes increased by 1.1 Mt or 5 percent, to 25.3 Mt since December 31, 2022 with the gold grade remaining unchanged at 0.47 g/t. The slight increase in Inferred Resources is due to minor adjustments in the optimization of the pit shell.

Yaramoko Mine, Burkina Faso

As of December 31, 2023, the Yaramoko Mine has Proven and Probable Mineral Reserves of 0.9 Mt containing 219 koz Au, in addition to Measured and Indicated Resources, exclusive of Mineral Reserves, of 0.5 Mt containing 43 koz Au, and Inferred Resources of 0.16 Mt containing 18 koz Au.

Year over year, Mineral Reserve tonnes decreased 26 percent, while gold grades increased 34 percent to 7.90 g/t Au. The changes are due to mining related depletion in 2023 of 0.5 Mt of material containing 118 koz Au offset by successful underground exploration and delineation drilling of the Zone 55 and Bagassi South QV Prime veins that, after the application of modifying factors, resulted in an increase of 0.3 Mt containing 124 koz Au of new Probable Reserves.

Measured and Indicated Resource gold ounces, exclusive of Mineral Reserves, decreased by 46 koz and Inferred Resources by 7 koz as a result of the application of updated cut-off grades and operational dilution based on mineable stope optimizer evaluation to remove isolated non-economic mineralization.
The Brownfields exploration program budget for 2024 at Yaramoko is $6.1 million, which includes 41,450 meters of exploration drilling, with underground drilling testing western and depth extensions to the Zone 55 deposit, surface drilling testing several anomalies along the Boni Shear, Bagassi South surface extensions, and other surface targets (refer to Fortuna news release dated January 18, 2024).

Séguéla Mine, Côte d'Ivoire

As of December 31, 2023, the Séguéla Mine has Proven and Probable Mineral Reserves of 11.8 Mt containing 1.2 Moz Au, in addition to Indicated Resources of 4.7 Mt containing 381 koz Au and Inferred Resources of 3.1 Mt containing 245 koz Au.

Since December 31, 2022, Mineral Reserve tonnes decreased by 3 percent, while gold grade increased by 9 percent to 3.05 g/t Au. Changes are primarily due to mining related depletion of 0.8 Mt of material containing 79 koz Au since operations commenced in May 2023, an increase in the reporting cut-off grade due to higher processing and service costs resulting in a decrease of 1.6 Mt containing 53 koz Au offset by the reclassification of 2.1 Mt containing 206 koz from Indicated Resources to Probable Reserves related to delineation drilling and definition of the updated pit shell at the Sunbird deposit.

Measured and Indicated Resource gold ounces, exclusive of Mineral Reserves, decreased 34 percent, by 142 koz, year-over-year, in relation to the reclassification of the Sunbird deposit open pit resources from Indicated Resources to Probable Reserves and a reduction in pit size based on updated contractor costs and geologic interpretation, a decrease of 339 koz Au. This reduction was offset by the inclusion of underground Indicated Resources for the Koula, Ancien and Sunbird deposits totaling 233 koz Au. The application of higher cut-off grades in relation to an increase in processing and service costs accounted for a further decrease of 36 koz Au.

Inferred Resources decreased 2.6 Mt or 365 koz Au in relation to the reduction in the size of the Sunbird pit shell due to the results of the infill drilling and increased costs as described above resulting in a decrease of 203 koz, and upgrading to Indicated Resources of underground mineralization, previously planned for open pit mining of 233 koz Au. These decreases were offset by the inclusion of underground Inferred Resources for the Koula, Ancien and Sunbird deposits totaling 98 koz Au. Adjustments to the estimation parameters and pit optimization for the other deposits resulted in a further decrease of 27 koz Au.

The Brownfields exploration program budget for 2024 at Séguéla is $7.8 million, which includes
41,750 meters of exploration drilling, focused on testing and extending underground targets associated with the Sunbird, Ancien, and Koula deposits, as well as advancing emerging prospects such as Barana, Badior, and Kestral, and continuing to explore for additional prospects (refer to Fortuna news release dated January 18, 2024).

Arizaro Gold Project, Lindero Property, Argentina

As of December 31, 2023, the Arizaro Gold Project has Inferred Mineral Resources of 24.1 Mt averaging 0.40 g/t Au containing 310 koz Au, remaining relatively unchanged from last year other than minor adjustments in the pit shell. Mineralization remains open at depth and along the trend of the northeast to southwest striking porphyry.
