Fortuna Mining Corp. has increased the Indicated Mineral Resource estimate at its Diamba Sud Gold Project in Senegal by 73%, bringing the total to 1.25 million ounces of gold as of January 16, 2026. The substantial resource upgrade was achieved through targeted infill drilling and resource conversion activities, which enhanced the geological understanding of the deposit and upgraded mineralization estimates to higher confidence categories.
The Southern Arc deposit has emerged as the project's primary asset, representing the largest gold mineralization identified to date. This progression positions Diamba Sud as a significant development opportunity within Fortuna's portfolio as the company advances toward commercial production.
Fortuna expects to complete a feasibility study by the end of the second quarter of 2026, a critical milestone that will evaluate the technical and economic viability of the project. The company's development strategy targets annual gold production exceeding 500,000 ounces, contingent on favorable feasibility outcomes and regulatory approvals.
