VANCOUVER, British Columbia, Nov. 02, 2026 (GLOBE NEWSWIRE) — Fortuna Mining Corp. (NYSE: FSM | TSX: FVI) is pleased to provide an update on its progress at the Diamba Sud gold project, Senegal.
Jorge A. Ganoza, CEO and Director of Fortuna, commented, “Following our July final investment decision on the 30% plant expansion at our flagship Séguéla mine, and with Diamba Sud advancing through the final stages of permitting, we are progressing along a clear growth path. Together, these projects underpin our target of approximately 60% growth in annual gold production to an annualized rate of 500,000 ounces from mid-2028.”
Permits
Fortuna is pleased to report that it received the Notice of Admissibility for its Diamba Sud Exploitation Permit application from Senegal’s Ministry of Mines and Geology on November 2, 2026, following initiation of the application process in February 2026. The notice confirms that the Ministry has completed the review of the application documentation, and the file complies with all regulatory requirements, marking an important final step toward the granting of the Exploitation Permit. The Company and the Ministry have worked constructively to advance the application to this stage. With this milestone completed, the Company now expects the Government´s internal approval process for the final Exploitation Permit to be completed during the fourth quarter of 2026.
The project has already received the environmental decree from Senegal’s Ministry of Environment and Ecological Transition approving its Environmental and Social Impact Assessment, as announced on June 15, 2026. Fortuna is advancing early works and committing capital to protect the project schedule and its target of first gold in mid-2028. The Company anticipates making a formal final investment decision (“FID”) upon receipt of the Exploitation Permit.
Mining Convention
Fortuna is at an advanced stage of negotiations with the State of Senegal on a new Mining Convention for the Diamba Sud project based on Senegal’s 2016 Mining Code, together with additional provisions intended to establish a fiscal stability framework for a ten-year period. The Convention remains subject to finalization and the required Government approvals.
Construction Planning and Early Works Advancing
Full-scale construction of the mine remains subject to receipt of the Exploitation Permit, Board approval of the FID and some local level customary construction approvals. The results of the positive feasibility study (“FS”) announced on June 29, 2026 demonstrated the project’s technical and economic viability (refer to Fortuna news release dated June 29, 2026, “Fortuna delivers robust Feasibility Study for the Diamba Sud Gold Project in Senegal: After-tax IRR of 60% and NPV5% of US$1 billion using US$3,500/oz”).
Early works completed or underway to support the project schedule include:
- Assembly of the owner’s construction team, with a core of professionals largely drawn from the team that successfully delivered Fortuna´s flagship Séguéla mine in Cote d’Ivoire
- Selection of SENET, a leading African project management and engineering company, as the project’s engineering, procurement and construction management contractor, and award of a limited order to proceed to advance early works
- Completion of front-end engineering and design
- 15% progress on detailed engineering for the processing plant
- Purchase orders placed and down payments for critical long-lead equipment, including the semi-autogenous grinding (“SAG”) mill, primary crusher, and carbon-in-leach tank plate work
- Manufacturing of the power station’s heavy fuel oil (“HFO”) and light fuel oil (“LFO”) generators with the LFO generators passing factory acceptance testing and shipped
- Tendering and award of key construction packages, including, bulk earthworks for process plant, water storage facility, tailings storage facility, power station, and fuel storage facilities
- New accommodation camp earthworks 80% complete, civil works 40% complete and buried services nearing completion
- Land compensation and clearing for major infrastructure footprints
