Fortuna Reports Results for the Second Quarter of 2025

(Results from the Company’s San Jose and Yaramoko assets have been excluded from its Q2 2025 continuing results, along with the comparative figures, due to the classification of the assets as discontinued as at June 30, 2025.)

Jorge A. Ganoza, President and CEO of Fortuna, commented, “Fortuna completed the second quarter with liquidity of more than half a billion dollars. Our strong balance sheet positions the Company to pursue growth opportunities under our control including the guided production expansion at the Séguéla Mine in 2026 and advancing to a construction decision at the Diamba Sud project in Senegal by the first half of 2026 following the completion of a PEA later this year.”

Mr. Ganoza continued, “We delivered a total of 75,950 gold equivalent ounces¹, keeping us firmly on track to meet annual production guidance. Higher realized gold prices in the quarter contributed to a record EBITDA¹ margin of 55%. The higher consolidated AISC¹ of $1,932 per ounce of gold in the quarter was primarily driven by the timing of capital expenditures and peak mine waste stripping at Séguéla during the second quarter and into the third. These investments are critical to achieving our annual target of 160 to 180 thousand gold ounces in 2026.”

Mr. Ganoza concluded, “Looking into the second half of the year, we expect our mines to remain within annual AISC¹  guidance. At Séguéla, AISC¹,  is projected to trend higher through the year due to planned mine waste stripping to access higher-grade material, but the full-year average is expected to remain well within guidance. In contrast, Lindero’s AISC¹,  is expected to trend lower in the second half of the year as the leach pad expansion is now complete and peak stripping is behind us.”

This estimate incorporates initial resources from the newly discovered mineralization at the Southern Arc prospect. The Company is advancing the Diamba Sud project with parallel activities on environmental permits, engineering studies, and continued mineral exploration working towards a preliminary economic assessment in the fourth quarter of 2025. Refer to our news release “Fortuna Advances Diamba Sud Gold Project in Senegal with Updated Mineral Resources; PEA Completion Targeted for Q4 2025” dated August 5, 2025.

Yaramoko and San Jose Divestment

The Company received $83.8 million in gross proceeds during the quarter related to the divestment of our two short-life mines as part of an initiative to streamline the asset portfolio. Taken together, these two sales allow the Company to reallocate approximately $50.0 million in capital and management focus away from mine closures and toward higher-value opportunities that align more closely with our long-term strategy.
