Fortuna’s Diamba Sud Gold Project Nears Senegal Permit
Africa · Western
Key Facts
—Permit imminent. Fortuna expects Senegal’s final exploitation permit within weeks, following environmental approval in June 2026.
—Capital cost. Initial capex stands at US$397.5 million, making it one of Senegal’s largest single mining investments.
—Production profile. The open-pit mine targets 158,000 ounces annually in early years, with first gold expected by mid-2028.
—State stake. Senegal receives a 10% free-carried interest automatically, with an option to buy up to 35% total.
—Strong economics. The feasibility study shows a post-tax net present value of US$1 billion and an internal rate of return near 60%.
Senegal is weeks away from granting Canadian miner Fortuna the final permit for its Diamba Sud gold project, a nearly US$400 million investment that signals Dakar’s ambition to become West Africa’s most predictable mining jurisdiction.
A permit in weeks, not years
Fortuna Mining’s chief executive Jorge Ganoza told Reuters on 9 July that the company is “only now waiting for our final construction permit.” He added that approval “should come in a matter of weeks.”
The environmental decree was already issued on 15 June 2026 by Senegal’s Ministry of Environment and Ecological Transition. That document certified regulatory compliance and confirmed “social acceptance” by project stakeholders, clearing the last major hurdle before the exploitation permit.
The speed of the process has caught investors’ attention. Fortuna submitted its environmental and social impact assessment in October 2025 and received approval roughly nine months later, a timeline the CEO contrasted favourably with multi-year delays in Peru, Mexico and parts of North America.
What the Diamba Sud gold project delivers
The Diamba Sud gold project sits in Senegal’s Kédougou Region, about 665 kilometres southeast of Dakar and 50 kilometres north of the Guinea border. It lies within the Kenieba-Koudougou Inlier, a Birimian greenstone belt already hosting world-class deposits in neighbouring Mali.
The feasibility study, published on 29 June 2026, outlines an open-pit mine using conventional carbon-in-leach processing across seven deposits. Probable reserves stand at 20.5 million tonnes grading 1.75 grams per tonne, containing roughly 1.1 million recoverable ounces.
Average production during the first four years is projected at 158,000 ounces annually, with peak output reaching around 230,000 ounces. Over a 9.4-year mine life, total production should approach one million ounces, with first gold expected before the end of the second quarter of 2028.
The numbers that make boards pay attention
At a gold price of US$3,500 per ounce, the Diamba Sud gold project generates a post-tax net present value of US$1 billion at a 5% discount rate. The internal rate of return reaches roughly 60%, with capital payback in about one year.
Even at a more conservative US$2,750 gold price, the earlier preliminary economic assessment showed an after-tax net present value of US$563 million and a 72% internal rate of return. All-in sustaining costs are estimated at US$1,056 per ounce in early years and US$1,332 over the full mine life.
Initial capital expenditure is set at US$397.5 million, including US$72.1 million in pre-production costs and US$33.7 million in contingency. An early-works budget of roughly US$73 million will fund access roads, camp expansion and site infrastructure before full construction begins in the fourth quarter of 2026.
Senegal’s calibrated resource play
Under Senegal’s mining code, the government automatically receives a 10% free-carried interest in the project company, Boya SA, upon granting the exploitation permit. Dakar may also purchase up to an additional 25% at a fair price determined by independent valuation.
This structure gives the state a potential 35% stake, enough for a blocking minority, without resorting to the contract revisions or expropriations seen elsewhere. Business press commentary describes the approach as “resource nationalism lite,” balancing tougher ownership terms with efficient, predictable permitting.
The strategy appears calibrated to attract capital that might otherwise flow to less stable neighbours. As military-ruled Mali and coup-hit Burkina Faso face sanctions and security crises, Senegal is positioning itself as the region’s safe port for Western mining investment, a dynamic explored in our pillar Africa: The New Scramble.
The great-power backdrop to a gold mine
Diamba Sud is led by a Canadian-listed company financed through Western capital markets. In neighbouring countries, Chinese state-owned enterprises and Russian-linked firms have expanded their presence in bauxite, iron ore and gold, though no such interests are reported in this specific project.
The regional pattern matters. Ensuring that strategic gold belts remain accessible to Western capital, rather than locked into rival spheres of influence, is a quiet but real component of economic statecraft.
Diamba Sud anchors TSX and NYSE-listed capital in a politically moderate coastal state at a moment when gold’s role as a reserve asset is growing.
For Latin American readers, the contrast is instructive. Fortuna operates mines in Peru, Mexico and Argentina, where permitting timelines stretch far longer.
Senegal’s nine-month environmental review offers a competitive benchmark that some Latin American jurisdictions may struggle to match.
What to watch next
The final investment decision is expected immediately after the exploitation permit is granted, likely within weeks. Full construction would then start in the fourth quarter of 2026, after the wet season, with first gold targeted for mid-2028.
Several risks bear monitoring. Community expectations for jobs and infrastructure will rise once earthworks begin, and any failure to deliver visible benefits could trigger protests.
Senegal’s fiscal position may also create pressure to revisit mining contracts during the mine’s long life, testing the durability of the current framework.
For now, the Diamba Sud gold project represents a US$400 million bet that a mid-sized African democracy can out-compete its neighbours not by offering the cheapest terms, but by offering the most reliable ones.

Frequently Asked Questions
When will the Diamba Sud gold project receive its final permit?
Fortuna’s CEO told Reuters in early July 2026 that the exploitation permit is expected “in a matter of weeks.” The environmental decree was already issued on 15 June 2026, leaving the mining permit as the last regulatory step before a final investment decision.
How much gold will Diamba Sud produce?
The feasibility study projects average production of 158,000 ounces annually during the first four years and roughly 116,000 ounces over the 9.4-year mine life. Total life-of-mine output is estimated at about one million ounces, with peak annual production reaching approximately 230,000 ounces.
What stake does Senegal hold in the Diamba Sud gold project?
Senegal automatically receives a 10% free-carried interest upon granting the exploitation permit. The government may also purchase up to an additional 25% at an independently determined fair price, potentially giving it a 35% total stake and a blocking minority in the project company Boya SA.
