Mining
Mine production for the quarter totaled 340,426 tonnes of ore, averaging 3.3 g/t Au, and containing an estimated 36,482 ounces of gold from the Antenna, Ancien, and Koula pits. A total of 5,194,192 tonnes of waste was moved during the period, resulting in a strip ratio of 15.3:1.
Processing
In the second quarter of 2025, Séguéla produced 38,186 ounces of gold at an average head grade of 3.0 g/t Au, representing a 0.8 percent decrease in ounces produced and an 8.6 percent increase in grade compared to the first quarter of 2025.
Gold recoveries and mill throughput declined slightly during the quarter, attributed to maintenance on one of the carbon-in-leach processing tanks in June. Despite this, mill throughput averaged 210 tonnes per hour, exceeding nameplate capacity by 36 percent.
Year-to-Date Production
Séguéla produced a total of 76,686 ounces of gold in the first half of 2025, in line with the upper end of annual production guidance.
Yaramoko Mine, Burkina Faso: Sale completed in May 20251

Gold recovery (%) | 97.68 | 97.43 |
Gold production3(oz) | 4,721 | 33,073 |
Notes:
In May 2025, Fortuna leveraged favorable precious metals market conditions and continued to optimize its asset portfolio with the completion of the sale of the Yaramoko Mine, which had approximately one year of mineral reserves remaining. As a result, the Company no longer has any operations in Burkina Faso.
As part of the agreement for the sale of the Company’s Burkinabe assets with Soleil Resources, the assumed handover of operations at the Yaramoko Mine was effective April 14, 2025. As of this date, 20,666 tonnes of ore were treated at an average head grade of 7.28 g/t Au, producing 4,721 ounces of gold. Mining was focused at the 55 Zone, QV Prime, and the 109 Zone open pit.
As of April 14, 2025, Yaramoko had produced a total of 37,794 ounces of gold year to date.

Lindero Mine, Argentina: On track to meet annual production guidance

Ore placed on pad (t) | 1,828,520 | 1,753,016 |

Mining
Mining operations delivered another quarter of strong and consistent performance in the second quarter of 2025, aligning with management’s annual mine plan. Lindero mined 1.32 million tonnes of ore with an efficient strip ratio of 2.3:1. Furthermore, 1.83 million tonnes of ore were placed on the leach pad, a 4 percent increase over the previous quarter, with an average head grade of 0.57 g/t Au, containing an estimated 33,219 ounces of gold.
Processing
Lindero produced 23,550 ounces of gold during the quarter, including 21,153 ounces in doré bars, 1,214 ounces in rich fine carbon, 72 ounces in copper precipitate, and 1,111 ounces in precipitated sludge.
The 16 percent increase in production compared to the first quarter was driven by a 4 percent higher gold grade, 4 percent more ore placed on the pad, and recovery of non-leached inventory stacked in the previous quarter. Production remains in line with the planned mining and stacking sequence.
Energy Efficiency and Cost Optimization
The 14.5 MWh photovoltaic plant was successfully completed and commissioned on schedule. In June 2025, it generated 1 million kWh, supplying 26 percent of Lindero’s power demand. The plant’s performance means Lindero was able to eliminate the need for 286,300 liters of diesel, which is equivalent to 35 percent of the operation’s typical monthly diesel consumption, contributing to both cost efficiency and reduced greenhouse gas emissions.
Plant Performance with crushing capacity significantly enhanced at Lindero, achieving new milestones
During the first half of 2025, the project to increase crushing plant capacity was consolidated, achieving an average throughput of 1,050 tonnes per hour (tph) in the second quarter, 11 percent above the 2024 average. In June, a record average throughput of 1,109 tph was achieved. This performance places Lindero on track to meet annual production guidance.
Year-to-Date Production
Lindero produced a total of 43,870 ounces of gold in the first half of 2025.
