Fortuna drills 22.7 g/t gold over 21.6 meters at Southern Arc, Diamba Sud Gold Project, Senegal

Core Viewpoint - Fortuna Mining Corp. has reported promising exploration drilling results from the Southern Arc deposit at the Diamba Sud Gold Project in Senegal, indicating potential for resource growth and further exploration planned for the upcoming months [1][2][5]. Exploration Results - The exploration drilling at the Southern Arc deposit has yielded several high-grade intercepts, with notable results including drillhole DSDD488, which intersected 22.7 g/t Au over an estimated true width of 21.6 meters [2][3]. - Additional highlights from the drilling program include: - DSDD418: 6.3 g/t Au over 18.2 meters, including 23.3 g/t Au over 0.8 meters [3]. - DSDD440: 6.3 g/t Au over 16.8 meters, including 19.4 g/t Au over 0.8 meters [3]. - DSDD462: 9.7 g/t Au over 20.8 meters, including 21.9 g/t Au over 2.2 meters [3]. - DSDD488: 22.7 g/t Au over 21.6 meters, including 258.8 g/t Au over 1.6 meters [3]. Drilling Program Details - A total of 152 reverse circulation and diamond core drill holes have been completed, amounting to 21,234 meters since the last update [4]. - The drilling program has been paused due to the rainy season, with plans to resume in mid-September [4]. - Of the 152 drill holes, 53 were completed after the data cutoff for the maiden Inferred Mineral Resource estimate of 3.9 million tonnes averaging 1.57 g/t Au, containing 194,000 ounces of gold [5]. Mineralization Characteristics - Mineralization at the Southern Arc deposit is characterized by fine stockwork vein arrays and pyrite-silica flooding, with a strong correlation to tectonic breccias and carbonate units [6]. - The mineralization remains open at depth and along strike to the south and east, indicating further exploration potential [2][6]. Future Plans - Drilling is scheduled to resume in September, with further results expected by year-end, and an updated resource estimate planned for the first quarter of 2026 [2][5].
