Fortuna Mining Corp. (NYSE: FSM, TSX: FVI) has secured the environmental decree from Senegal's Ministry of Environment and Ecological Transition for the Diamba Sud Gold Project. This authorization confirms that the project complies with all applicable environmental regulations and has achieved social acceptance from stakeholders. The approval represents a decisive step toward obtaining the mining permit, following the submission of the application to the Ministry of Energy, Petroleum, and Mines on February 4, 2026.

Jorge A. Ganoza, President and CEO, stated that obtaining the environmental permit just nine months from submission demonstrates the quality of the company's work and the competitive timeline for mining projects in Senegal. He highlighted the Government of Senegal's commitment to responsible mining sector development. With this approval, Fortuna will continue advancing early construction works, including camp construction and placing purchase orders for critical-path equipment packages, while targeting a final investment and construction decision in mid-2026.

The Diamba Sud Gold Project is in the late stages of permitting and feasibility. A Preliminary Economic Assessment (PEA) outlined robust project economics, including an after-tax Internal Rate of Return (IRR) of 72% and a Net Present Value (NPV5%) of US$563 million, based on a gold price of US$2,750 per ounce. The 2026 project budget is US$100 million. The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to be categorized as mineral reserves, meaning there is no certainty the results will be realized.

PEA Key Highlights

Fortuna Mining Corp. is a Canadian precious metals mining company with three operating mines and a portfolio of exploration projects in Argentina, Côte d'Ivoire, Guinea, Guyana, and Peru, as well as the Diamba Sud Gold Project in Senegal.
