06:43 AM EDT, 08/13/2025 (MT Newswires) -- Fortuna Mining ( FSM ) was at last look up 1.1% in US pre-market trade on Wednesday as it reported additional exploration drilling results from the Southern Arc deposit at the Diamba Sud Gold Project in Senegal

A statement noted this follows the July 7, 2025 resource update.

Senior Vice President of Exploration Paul Weedon said, "Exploration drilling at the Southern Arc deposit has continued beyond the data cut-off date for its maiden resource estimate, returning several high-grade intercepts. Highlights include drillhole DSDD488, which intersected 22.7 g/t Au over an estimated true width of 21.6 meters from a downhole depth of 53 meters."

Weedon added: "These results further demonstrate the potential for resource growth at Diamba Sud. The deposit remains open to the south, east, and at depth, with current drilling only extending to approximately 150 meters. Drilling is scheduled to resume in September, following the end of the rainy season, with further results expected by year-end."

Fortuna rose more than 4% on the TSX on Tuesday.
