The company, which has taken control of several mining assets in West Africa, reflects a broader evolution in the sector: the growing role of private investment funds and sovereign capital in projects that were once dominated by large listed mining groups. Mansa Resources also illustrates how investors are increasingly targeting existing operations with turnaround potential rather than focusing solely on new exploration.

While the company remains at an early stage, the profile of its backers has attracted attention across the mining industry, particularly given de Montessus’s return to the sector less than two years after his departure from Endeavour Mining.
A strategy centred on existing assets
Mansa Resources has so far concentrated on projects that already possess infrastructure and defined mineral reserves. Among them are the Kouroussa mine in Guinea and the Dugbe project in Liberia, both previously linked to Hummingbird Resources.
This approach differs from the traditional model adopted by many junior mining companies, which often rely heavily on exploration programmes and long development timelines. Instead, Mansa appears to be positioning itself around the acquisition and rehabilitation of underperforming or financially constrained assets.
The strategy reflects broader trends in the gold industry. Rising construction costs, tighter financing conditions and growing political uncertainty in several mining jurisdictions have made investors more cautious about large greenfield developments. Existing projects with operational difficulties can offer lower entry valuations, even if they require substantial restructuring.
Industry analysts note that this type of model has become more common as mining companies seek ways to preserve margins while avoiding some of the risks associated with entirely new projects.
Idrissa Nassa’s vision for Mansa
Burkinabe businessman Idrissa Nassa, founder of Coris Bank International, is a key figure behind Mansa Resources.
Following the acquisition of Hummingbird Resources, he has positioned Mansa as a new mining platform in West Africa. The arrival of Sébastien de Montessus brings additional operational expertise to support the company’s growth ambitions.
Orion and the rise of specialist mining finance
The involvement of Orion Resource Partners is central to understanding Mansa’s financial structure.
The New York-based fund has become one of the most influential specialist investors in mining over the past decade, financing projects across a range of commodities and jurisdictions. Unlike traditional banks, specialist funds such as Orion are often willing to invest in more operationally or politically complex situations, provided the underlying assets are considered viable.
That role has grown as mainstream lenders have reduced exposure to frontier-market mining projects. Access to financing has become more selective in recent years, particularly for operations located in countries facing political instability or infrastructure constraints.
Orion’s participation therefore provides more than capital. It also offers technical and financial expertise that can help companies navigate restructuring processes and operational recovery.
For Mansa Resources, the partnership may help reassure investors concerned about the risks associated with operating in West Africa, where security challenges and regulatory changes have complicated the outlook for several mining groups.
ADQ’s increasing presence in African resources
The participation of ADQ reflects the expanding role of Gulf sovereign wealth funds in Africa’s resource sectors.
Over recent years, investors from the United Arab Emirates and Saudi Arabia have increased their presence across African infrastructure, logistics, agriculture and mining projects. The trend has accelerated as Gulf states seek to diversify their economies and secure long-term exposure to strategic commodities.
Gold remains particularly attractive because of its role as both a financial asset and a globally traded commodity less dependent on industrial demand cycles than metals such as copper or lithium.
For sovereign funds such as ADQ, mining investments also provide geopolitical as well as financial opportunities. Gulf countries have strengthened economic ties with African governments through investments in ports, transport infrastructure and energy projects, creating broader commercial relationships that extend beyond mining alone.
In that context, Mansa Resources fits within a wider pattern of Gulf-backed investments in African natural resources.
The return of Sébastien de Montessus
The operational leadership of Mansa Resources rests largely with Sébastien de Montessus.
During his time at Endeavour Mining, de Montessus oversaw a period of expansion that transformed the company into one of the largest gold producers operating in West Africa. Through acquisitions including Semafo and Teranga Gold, Endeavour increased production and strengthened its position across several countries in the region.
Analysts credit him with improving operational performance and consolidating assets in markets where logistical and political risks often complicate mining operations.
His experience consolidating mid-tier African gold producers is central to Mansa’s acquisition-led strategy.
Mining in a changing political environment
Mansa Resources is entering the market at a time when African governments are seeking greater economic returns from extractive industries.
Several countries in West Africa have revised mining regulations in recent years, increasing royalty expectations or strengthening state participation in projects. Governments have argued that previous models often generated insufficient local economic benefits despite strong commodity revenues.
At the same time, mining companies face increasing scrutiny over environmental and social impacts. Civil society organisations and local communities have raised concerns over land use, pollution, employment practices and the distribution of mining revenues.
Security remains another major issue. Political instability and armed violence in parts of the Sahel have increased operational risks for companies across the region, even in countries not directly affected by conflict.
For operators such as Mansa Resources, maintaining stable relations with governments and local stakeholders may prove as important as geological performance or gold prices.
A test for a new mining model
The structure of Mansa Resources reflects broader changes in how mining projects are financed and managed.
Large listed mining companies still dominate global production, but specialist funds, sovereign investors and privately backed platforms are playing a growing role in acquisitions and project development. The shift has been driven partly by the increasing complexity of mining projects and partly by shareholder pressure on listed groups to reduce risk exposure.
Mansa combines several of these trends: sovereign capital from the Gulf, specialist mining finance from the United States and operational leadership with deep experience in African gold mining.
Whether the company succeeds will depend on its ability to stabilise and develop its assets in a region where mining remains both economically important and politically sensitive.
For now, Mansa Resources represents less a transformative new entrant than an example of the changing financial and strategic alliances reshaping Africa’s mining industry.
