Fortuna reports third quarter 2026 production of 69,665 gold equivalent ounces and advances key growth initiatives | Strikepoint News
GEO includes gold, silver, lead, and zinc and is calculated using the following metal prices: $4,446/oz Au, $75.21/oz Ag, $1,930/t Pb and $3,464/t Zn, or Au:Ag = 1:59.11, Au:Pb = 1:2.30, Au:Zn = 1:1.28.
GEO includes gold, silver, lead, and zinc and is calculated using the following metal prices: $3,467/oz Au, $39.35/oz Ag, $1,962/t Pb and $2,815/t Zn, or Au:Ag = 1:88.10, Au:Pb = 1:1.77, Au:Zn = 1:1.23.
During the third quarter of 2026, Séguéla mined 340,714 tonnes of ore at an average grade of 2.69 g/t Au from the Antenna, Ancien, Sunbird, and Koula pits, containing an estimated 29,516 ounces of gold. This compared with 433,231 tonnes of ore mined at an average grade of 3.06 g/t Au in the second quarter of 2026, containing an estimated 42,555 ounces of gold. Waste mined during the quarter totaled 6.5 million tonnes, resulting in a strip ratio of 19.1:1. At the Sunbird South pit, a further 623,390 tonnes of waste were excavated to advance access to the planned portal location for the Sunbird underground mine.
Third quarter mining performance and gold production were affected by reduced equipment availability at one of the Company’s mining contractors and a temporary site-wide stoppage caused by a blockade by artisanal miners operating in the surrounding area. The blockade was lifted following intervention by a government law enforcement agency, and normal operations resumed. These disruptions reduced mining volumes and delayed access to higher-grade ore. Corrective measures were implemented with the mining contractor, and mining volumes returned to planned levels in September.
Processing
Séguéla produced 33,744 ounces of gold in the third quarter of 2026, compared with 41,683 ounces in the second quarter, reflecting lower tonnes milled, head grade, and recovery. The plant processed 402,440 tonnes at an average head grade of 2.67 g/t Au and at a recovery rate of 90.75%.
Gold production is expected to recover to first-half 2026 levels in the fourth quarter as mining volumes normalize and access to higher-grade ore improves. The 1.35% quarter-over-quarter decrease in plant recovery was attributed to localized metallurgical characteristics of the Koula ore.
Year-to-date production
Séguéla produced 117,443 ounces of gold in the first nine months of 2026 and remains on track to achieve the lower end of its annual production guidance.
Project Updates
30% Plant Expansion
During the third quarter, the Board approved a $109 million budget for a 30% expansion of the Séguéla processing plant. The expansion will increase annual throughput to 2.3 million tonnes, restore gold recoveries to the original design rate of 94%, and support annual gold production target of over 200,000 ounces from the second half of 2028.
Detailed engineering is underway with Lycopodium, the EPCM contractor. The owner’s project team is 75% onboarded, and vendors have been selected for key equipment and infrastructure packages. Project completion and commissioning are scheduled for the third quarter of 2028.
Sunbird Underground Project
The Sunbird Underground Project, which is expected to begin supplying mill feed to the expanded plant in 2028, continued to advance during the quarter. The Environmental and Social Impact Assessment (“ESIA”) has been approved, with final permitting expected in the fourth quarter of 2026.
The underground project team has been recruited and is advancing pre-development and operational readiness activities. Major mining equipment has been ordered for delivery in line with the project schedule, and portal construction and development are expected to commence in the second quarter of 2027.
The underground mine design supports expected steady-state production of approximately 1 million tonnes per annum, equivalent to 40% of the expanded plant throughput.
The Sunbird underground deposit remains open at depth, with additional drilling planned from future underground platforms to test its growth potential.
Exploration Activities
Exploration during the quarter focused on converting Inferred Mineral Resources at the Sunbird Underground and Kingfisher deposits and on step-out drilling beyond the boundaries of the current Inferred Resources.
During the fourth quarter of 2026 and into 2027, drilling will focus on other priority targets, including the underground potential at Ancien, southern and depth extensions to the Antenna pit, and emerging prospects across the Séguéla property.
Diamba Sud Gold Project, Senegal: Drilling commences at the Bambadji property
During the third quarter of 2026, Fortuna acquired the 190 km² Bambadji advanced gold exploration project, immediately adjacent to Diamba Sud. The acquisition consolidates approximately 60 kilometers of prospective strike along the Senegal-Mali Shear Zone, where exploration has commenced with six drill rigs.
Diamba Sud continues to advance toward a final investment decision in the fourth quarter as the Company completes the final stages of negotiations for the tax stability agreement with the State of Senegal. First gold pour remains on track for the second quarter of 2028.
Latin America region
Lindero Mine, Argentina: Gold production increases 25% quarter-over-quarter; on track to meet annual guidance
Production includes doré, gold-in-carbon, and gold in copper concentrate.
Mining
During the third quarter of 2026, Lindero mined 2.3 million tonnes of ore at a strip ratio of 0.85:1 and stacked 1.9 million tonnes on the leach pad at an average grade of 0.63 g/t, containing an estimated 37,746 ounces of gold. Gold ounces placed on the leach pad increased by 18% compared with the second quarter, driven by improved mechanical availability across the processing circuit and higher crushing and stacking rates.
During the first nine months of 2026, Lindero placed approximately 99% of the planned gold ounces for the period on the leach pad.
Processing
Lindero produced 26,024 ounces of gold in the third quarter of 2026, a 25% increase from the second quarter and consistent with the second-half operating plan.
Year-to-date production
Lindero produced 68,398 ounces of gold in the first nine months of 2026 and remains on track to achieve its annual production guidance.
Exploration activities
Drilling to test extensions of mineralization beneath the ultimate Mineral Reserve pit shell at Lindero was completed as planned during the quarter. Assay results have been reported from the commercial laboratory and will be evaluated to determine the potential for future resource growth.
Caylloma Mine, Peru: On track to exceed annual production guidance; tailings storage expansion 64% complete
Metallurgical recovery for silver is calculated based on silver content in lead concentrate.
GEO production includes gold, silver, lead, and zinc and is calculated using the following metal prices: $4,281/oz Au, $62.70/oz Ag, $1,871/t Pb and $3,832/t Zn, or Au:Ag = 1:68.27, Au:Pb = 1:2.29, Au:Zn = 1:1.12.
GEO production includes gold, silver, lead, and zinc and is calculated using the following metal prices: $4,446/oz Au, $75.21/oz Ag, $1,930/t Pb and $3,464/t Zn, or Au:Ag = 1:59.11, Au:Pb = 1:2.30, Au:Zn = 1:1.28.
Mining
Caylloma mined 139,868 tonnes of ore in the third quarter of 2026, in line with the mine plan. Plant throughput of 140,832 tonnes was broadly consistent with the second quarter, with the difference between tonnes mined and processed reflecting the use of ore stockpile.
Processing
During the third quarter, Caylloma produced 247,367 ounces of silver, a 7% increase from the second quarter, supported by a higher average head grade of 66 g/t and improved recovery. Zinc and lead production totaled 11.4 million pounds and 8.4 million pounds, respectively, at average head grades of 4.08% zinc and 2.98% lead.
The quarter's performance reflects steady plant operations, consistent throughput, and continued strong contribution from base metal production.
Year-to-date production
Caylloma produced 9,897 GEO in the third quarter and 28,913 GEO during the first nine months of 2026, close to the lower end of its annual guidance range of 29,000 to 33,000 GEO and positioning the operation to exceed its annual guidance by year-end.
Project update
As of September 30, 2026, the expansion of the tailings storage facility No. 3 was approximately 64% complete and on schedule for completion by year-end. The expansion is expected to provide the additional tailings storage capacity required to support operations for several more years.
