Watch for Q4 2026 production recovery at Seguela to first-half levels as management expects normalization. The Diamba Sud final investment decision in Q4 2026 and Seguela expansion timeline (completion Q3 2028) are key medium-term catalysts. Monitor Q4 operational update for confirmation that Seguela disruptions are resolved.

Executive Summary
Fortuna Mining reported Q3 2026 production of 69,665 gold equivalent ounces (GEO), down 4% from Q2 2026 (72,217 GEO) and 3.9% from Q3 2025 (72,462 GEO). The decline was driven by a 19% drop at the Seguela mine due to contractor equipment issues and a temporary artisanal miner blockade, partially offset by a 25% increase at Lindero. The company reaffirmed its 2026 annual guidance of 281,000-305,000 GEO and approved a $109 million 30% expansion of the Seguela plant targeting >200,000 oz/year from H2 2028. The production miss at the flagship Seguela mine is the key negative, while the growth capex and Lindero recovery provide offsets.
