Fortuna Mining (NYSE: FSM; TSX: FVI) has boosted the mineral resource count for its Diamba Sud gold project in Senegal ahead of a preliminary economic assessment (PEA) later this year.
The Diamba Sud project now contains 724,000 ounces of gold in indicated resources, a 53% increase on the previous estimate since year-end 2024. The inferred resource also rose by 93% to 285,000 gold ounces.
The resource covers seven deposits — Area A, Area D, Karakara, Western Splay, Kassassoko, Southern Arc and Moungoundi — based on drilling data from a total of 1,178 diamond and reverse circulation holes completed since 2019.
The update incorporates over 31,000 metres of drilling (243 holes) completed on the property for the one-year period up until July 2025. It includes the first estimates for the Southern Arc and Moungoundi deposits, containing 194,000 and 31,000 ounces respectively.
