Fortuna Mining is paying US$200 million to acquire the Bambadji gold project in southeastern Senegal, consolidating exploration ground adjacent to its Diamba Sud project.

Fortuna Mining has agreed to acquire the Bambadji advanced gold exploration project in Senegal from Barrick Mining Corporation and IAMGOLD Corporation for US$200 million in cash, according to company announcements and filings.
The transaction gives Fortuna control of a 190-square-kilometre land package in the Kédougou region of southeastern Senegal, close to the border with Mali. Bambadji is immediately adjacent to Fortuna’s feasibility-stage Diamba Sud Gold Project, allowing the company to consolidate approximately 60 kilometres of prospective strike along the Senegal-Mali Shear Zone.
The deal comes as gold producers and developers continue to consolidate established exploration districts in West Africa. For Fortuna, the acquisition adds a large historical exploration dataset and a portfolio of drill-defined targets to a region where the company already has a more advanced development asset.
Deal terms and ownership
Bambadji was previously held through a joint venture between subsidiaries of Barrick and IAMGOLD. Barrick held a 65% interest, while IAMGOLD held the remaining 35%.
IAMGOLD said in an Aug. 10 company filing that it had completed the sale of its indirect interest in the Bambadji joint venture and its attributable interest in the Bambadji Sud exploration permit to Fortuna.
The consideration payable on a combined 100% basis includes:
| Transaction element | Details |
|---|---|
| Cash consideration | US$200 million |
| Payment to Barrick subsidiary | Approximately US$130.35 million |
| Payment to IAMGOLD subsidiary | Approximately US$69.65 million |
| Retained royalty | 0.5% net smelter return royalty |
| Royalty cap | First 1.75 million ounces of gold produced from the Bambadji permit |
| Previous joint venture ownership | Barrick 65%; IAMGOLD 35% |
IAMGOLD said its share of the proceeds was approximately US$70 million before taxes and transaction costs. The company described Bambadji as a non-core exploration asset and said the divestiture would support its focus on its existing operating and development portfolio.
Barrick and IAMGOLD will retain their proportionate interests in the royalty. Fortuna is funding the cash payment from its treasury, according to the transaction details reported in the companies’ disclosures.
Large exploration package without a declared resource
Bambadji is an advanced exploration project, but the transaction disclosures do not report a compliant mineral resource for the property. Its value is instead based on the scale of the land position, historical drilling, geological interpretation and proximity to Diamba Sud.
The project contains approximately 214,000 metres of historical auger, reverse-circulation and diamond drilling. Previous work also includes geochemical, geophysical and lithological datasets compiled during the joint venture’s exploration programs.
That work has identified at least eight significant drill-defined prospects. Several mineralised trends remain open along strike and at depth, while multi-kilometre gaps remain across parts of the anomalous gold system.
According to Global Mining Review’s report on Fortuna’s announcement, the project includes several styles of mineralisation that are considered prospective within the district. These include analogues to the breccia-style mineralisation identified at Diamba Sud, as well as Yalea sericite-albitite and high-tourmaline Gara-style mineralisation.
The historical drilling is an important part of the acquisition case, but Fortuna will need to verify and reinterpret the existing data before it can be used in future resource estimation or mine planning. As with other early-stage gold assets, exploration results may not translate into economic resources or reserves.
Fortuna plans 51,000 metres of drilling
Fortuna has approved an initial US$8 million exploration program for Bambadji for the remainder of 2026. The program includes approximately 51,000 metres of reverse-circulation and diamond drilling, with work expected to begin in the third quarter.
The first phase will focus on eight priority targets within roughly 20 kilometres of the proposed Diamba Sud plant site. Fortuna also plans to continue generative exploration across the broader property to test additional mineralised trends.
The location of the priority targets could be significant for future project planning. If exploration identifies extensions or satellite deposits close to the proposed Diamba Sud infrastructure, the results could influence decisions around mine sequencing, processing capacity and the potential scale of a regional development.
That possibility remains preliminary. Fortuna has not disclosed a combined development plan for Diamba Sud and Bambadji, and exploration success would still need to be followed by resource definition, metallurgical testing, engineering studies, permitting and financing decisions.
Link to Diamba Sud
The strategic logic of the acquisition rests largely on Bambadji’s relationship with Diamba Sud.
Fortuna’s Diamba Sud project is at the feasibility stage and is reported in company disclosures as having mineral reserves containing approximately 1.15 million ounces of gold. Fortuna has indicated that a final investment decision is expected in the near term.
By acquiring Bambadji, Fortuna is extending its position across a continuous section of the Senegal-Mali Shear Zone. The company described the combined ground position as a district-scale opportunity in one of West Africa’s established gold corridors.
The shear zone hosts several major gold deposits and operating mines across Senegal and Mali. Its geological potential has attracted exploration by international and regional mining companies for decades, although project development in the region also depends on infrastructure, permitting, community relations and the broader security environment.
For Fortuna, a contiguous land package may offer operational advantages over a collection of isolated exploration permits. Exploration teams can apply consistent geological models, coordinate access and prioritize targets based on their distance from planned infrastructure.
The company will nevertheless face the practical challenge of converting a large exploration position into a defined and economically viable inventory. The 2026 drilling campaign is intended to establish whether Bambadji can materially expand the resource and mine-planning potential of the broader Diamba Sud district.
West African gold consolidation
The transaction is part of a broader pattern of portfolio reshaping in West African gold.
Large producers have increasingly sought to sell non-core exploration ground while retaining royalties or other forms of future exposure. Buyers, meanwhile, have looked for advanced exploration assets near existing projects, where regional consolidation can reduce exploration duplication and create optionality around future infrastructure.
For IAMGOLD, the Bambadji sale provides immediate cash from an asset that was not central to its current operating portfolio. Barrick receives cash for its majority interest while maintaining a capped royalty linked to potential future production.
Fortuna is taking on the exploration and development risk. Its immediate capital commitment is the US$8 million program, but a larger investment would be required if drilling supports a resource estimate and the company decides to advance a combined development concept.
Gold prices, capital costs, regional infrastructure and Senegal’s regulatory environment will all influence the economics of any future project. The acquisition therefore adds geological potential, but it does not by itself establish a mine timetable or production forecast.
What to watch next
The first milestones will be the start of drilling, the release of initial assay results and Fortuna’s assessment of the historical database.
Investors and industry observers are likely to focus on four questions:
- Can Fortuna confirm the continuity of the known mineralised trends?
- Do the eight priority targets support extensions near the proposed Diamba Sud plant site?
- Will drilling identify sufficient scale or grade to justify a combined district development concept?
- How will Bambadji affect Diamba Sud’s timing, capital requirements and potential mine plan?
The acquisition gives Fortuna a larger position in Senegal’s Kédougou region and immediate access to a substantial body of historical exploration work. The next stage will depend on whether the company can convert that data and land position into a defined mineral inventory.
For now, Bambadji remains an exploration growth opportunity rather than a producing asset. Fortuna’s planned 51,000-metre program will provide the first major test of whether the project can expand the company’s Senegal strategy beyond Diamba Sud.
