Fortuna Mining Corp. Reports Significant Updates on Diamba Sud
Fortuna Mining Corp. Updates Diamba Sud Gold Project Insights
Fortuna Mining Corp. (NYSE: FSM | TSX: FVI) recently announced an important update regarding the Diamba Sud Gold Project. This project is centered around substantial mineral resources, and the latest estimate as of July 7, 2025, reflects significant growth in both indicated and inferred resources.
Highlights of the Mineral Resource Update
The updated figures show that the indicated mineral resource has surged by 53 percent since the end of the previous year, now totaling an impressive 724,000 ounces of gold. Additionally, the inferred mineral resource has nearly doubled, standing at 285,000 ounces, which marks a notable 93 percent increase. These resources are the result of substantial drilling efforts and offer an optimistic outlook on the project's potential.
Noteworthy Resource Details
The Diamba Sud Gold Project features an indicated mineral resource of approximately 14.2 million tonnes, with an average gold grade of 1.59 g/t, while the inferred resource consists of 6.2 million tonnes at an average grade of 1.44 g/t. This new estimate comes from recent drilling campaigns conducted between July 2024 and July 2025 that involved 243 holes and accumulated over 31,650 meters of drilling. Notably, this update enhances the geological understanding and resource modeling across key areas, including Area A, Area D, Karakara, Western Splay, and Kassassoko.
Progress and Future Plans
Fortuna Mining is in the process of conducting a Preliminary Economic Analysis (PEA) of the Diamba Sud Gold Project, with targets set for completion by the end of 2025. This analysis will likely further refine expectations regarding the project’s economic viability and operational strategies.
Resource Estimates and Their Implications
Among the significant changes in estimates, infill drilling at various locations, including Area A, Area D, Karakara, Western Splay, and Kassassoko, greatly improved the geological interpretations and supported the conversion of inferred resources into indicated ones. New exploration at the Southern Arc and Moungoundi deposits has led to initial inferred estimates for these areas—194,000 ounces and 31,000 ounces, respectively.
Detailed Mineral Resource Insights
The total indicated mineral resources sum up to about 14.153 million tonnes, with a gold content of 724,000 ounces at a grade of 1.59 g/t. The inferred resources total to approximately 6.171 million tonnes, containing 285,000 ounces of gold at a grade of 1.44 g/t. These resources are reported on a 100% ownership basis.
Quality Control and Sampling Protocols
