Fortuna's Senegal Gold Project Gets Green Light, Paving Path to Production

VANCOUVER, British Columbia – June 15, 2026 – Fortuna Mining Corp. has secured a critical environmental decree for its Diamba Sud Gold Project in Senegal, a milestone that significantly de-risks the asset and moves the ambitious project one major step closer to a final construction decision. The approval, granted by Senegal’s Ministry of Environment and Ecological Transition, certifies that the project’s comprehensive Environmental and Social Impact Assessment (ESIA) complies with national regulations and has achieved social acceptance from local stakeholders.

This green light is more than a procedural step; it’s a powerful signal from both the company and the Senegalese government. For Fortuna, it unlocks the next phase of development and reinforces its path toward a final investment decision slated for mid-2026. For Senegal, it showcases a commitment to fostering a competitive and responsible mining sector.

Jorge A. Ganoza, President and CEO of Fortuna, lauded the efficiency of the process. “Obtaining the environmental permit for our future Diamba Sud Gold Mine, just nine months from submission to approval, is a clear testament to the quality of our work and demonstrates that mining projects in Senegal can advance on a highly competitive timeline,” he stated in a press release. This rapid turnaround is a key data point for other international firms weighing investments in West Africa, suggesting a government eager to facilitate growth while upholding its regulatory standards.

A Decisive Step in a Promising Jurisdiction

The environmental decree is the culmination of a rigorous assessment and marks the most significant hurdle cleared since Fortuna submitted its mining permit application on February 4, 2026. With this approval in hand, the Canadian-based precious metals miner can confidently advance its early works program. The company has already budgeted US$100 million for 2026 to fund camp construction and place purchase orders for critical long-lead equipment, demonstrating a strong conviction in the project's future.

Senegal's regulatory framework, governed by the 2016 Mining Code and a new, comprehensive Environmental Code enacted in 2023, is designed to balance economic development with environmental protection. The efficient handling of Fortuna’s application suggests the country’s administrative bodies are capable of executing this vision. By granting the decree, the Ministry of Environment and Ecological Transition has validated Fortuna’s plans for managing the project's ecological footprint and its engagement with local communities—a core requirement for long-term operational success.

This development positions Diamba Sud as a flagship project not only for Fortuna but for Senegal's entire mining industry. As the nation seeks to expand its resource-based economy beyond phosphates and heavy mineral sands, the successful advancement of a major gold mine sends a clear message to the global market: Senegal is open for business, provided you meet its standards.

Unpacking the Billion-Dollar Economics

While the environmental permit is a crucial operational milestone, the project's allure for investors is rooted in its robust financial projections. A Preliminary Economic Assessment (PEA) from late 2025 outlined compelling economics, projecting an after-tax Internal Rate of Return (IRR) of 72% and a Net Present Value (NPV) of US$563 million.

However, a closer look at the numbers reveals the high-stakes nature of the venture. These impressive figures are predicated on a gold price assumption of US$2,750 per ounce. While the mine plan itself was based on a more conservative US$2,300 per ounce, the project's ultimate profitability remains highly sensitive to the volatile global gold market. The PEA projects an all-in sustaining cost (AISC) of US$1,238 per ounce over the life of the mine, offering a substantial margin at the assumed price but highlighting the importance of cost control and market stability.

Furthermore, investors must weigh the inherent risks detailed in the PEA. The assessment is classified as 'preliminary' because it includes 'inferred mineral resources,' which are too geologically speculative to be categorized as proven reserves. As Fortuna itself cautions, there is no certainty that the PEA's results will be fully realized. The company’s next major milestone, a full feasibility study, will be critical in converting these resources into bankable reserves and solidifying the economic case.

The project’s structure also includes significant government participation. Upon the granting of the final exploitation permit, the Senegalese government is entitled to a 10% free-carried interest in the project and retains the right to acquire an additional 25% stake on a contributory basis. While standard practice in the region, this will materially impact the final economic returns for Fortuna's shareholders.

The Social License and Sustainability Test

In modern mining, a government permit is only one part of the equation; the 'social license to operate'—the ongoing acceptance from local communities—is equally vital. Fortuna's announcement that the decree certifies the project has been 'socially accepted' is a significant claim. This acceptance is underpinned by Senegal’s Mining Code, which mandates that mining companies contribute 0.5% of their turnover to a local development fund, ensuring a direct flow of capital into community-led projects.

This framework aims to transform resource extraction into a catalyst for regional socio-economic progress. However, the true test of this social contract will come during the construction and operational phases. Maintaining trust will require continuous and transparent engagement with local stakeholders, effective management of social impacts, and delivering on promises of local employment and business opportunities.

Fortuna, which operates a portfolio of mines across the Americas and Africa, emphasizes that sustainability is at the core of its strategy. The company's ESG performance at its existing operations in Argentina, Peru, and Côte d’Ivoire will be scrutinized as a predictor of its conduct in Senegal. For Diamba Sud to become a long-term success, it must prove to be a model not just of economic efficiency but also of responsible partnership with its host communities and diligent stewardship of the local environment.

With the environmental approval secured, Fortuna is now focused on the final leg of the permitting process: obtaining the exploitation permit from the Ministry of Energy, Petroleum, and Mines. While the path forward seems clear, the PEA's fine print wisely notes that the state retains the 'sovereign prerogative' to revisit fiscal terms. With Senegal reportedly preparing to adopt a new mining law in line with broader West African standards, the regulatory landscape remains dynamic. Fortuna's ability to navigate these potential shifts while advancing the project toward its mid-2026 construction decision will be a masterclass in modern resource development.
