ARM: Plans Nkamouna Cobalt Nickel Investment in Cameroon

• US-based American Renaissance Minerals (ARM) is working to advance Cameroon's Nkamouna cobalt-nickel-manganese project, with Aeternum Resources Inc. agreeing to acquire 100% of ARM.
• The previous mining permit for Nkamouna was withdrawn in February 2025, and ARM is seeking a new one. An initial investment of $85 million is planned, with production targeted within 18 months after a new permit takes effect.
• The Nkamouna deposit is considered one of Central Africa's most promising for critical energy transition metals.
• ARM brings expertise in mineral processing, financing, and global experience to the project.
• The initiative is supported by US capital, the US government, and a commitment to responsible development in partnership with Cameroon and a local company.

The Nkamouna deposit is recognized as one of Central Africa's most promising sites for cobalt and nickel, alongside manganese.

American Renaissance Minerals (ARM), a Washington D.C.-headquartered critical minerals development company, is working to advance the Nkamouna cobalt-nickel project. Aeternum Resources Inc. has recently agreed to acquire 100% of ARM, with the transaction expected to close in the fourth quarter of 2026. This initiative targets the Nkamouna polymetallic deposit, situated within the Lomié district of Cameroon's Haut-Nyong department, in the East region. The previous mining permit for the Nkamouna project was withdrawn in February 2025, and ARM is currently working with the Government of Cameroon to secure a new one. The company has earmarked an initial investment of $85 million for the project's development, with production targeted within 18 months after a new permit takes effect. The move underscores a deepening mining partnership between the governments in Yaoundé and Washington, signaling increased foreign direct investment into Cameroon's critical minerals sector.

The Nkamouna deposit is recognized as one of Central Africa's most promising sites for cobalt and nickel, alongside manganese. This makes the Cameroon Nkamouna mining project a key component in the global strategy for critical metals, essential for the ongoing energy transition. The presence of cobalt, nickel, and manganese in Cameroon positions the nation as a potential hub for these vital resources.

ARM, a company specializing in strategic minerals, brings considerable expertise to the Lomié mining investment. Its contributions include specialized knowledge in mineral processing, robust financing capabilities, and extensive global experience in developing similar projects. This comprehensive approach is designed to ensure efficient and effective extraction from the polymetallic gisement.

The development of the Nkamouna project is bolstered by a collaborative framework, benefiting from American capital and direct support from the United States government. This backing highlights the strategic importance placed on securing critical mineral supplies and fostering responsible development practices in key regions.

ARM has committed to a responsible development approach, working in partnership with the Cameroonian government and a local enterprise. This multi-stakeholder collaboration aims to ensure that the Cameroon critical metals development not only meets global demand but also contributes positively to local economies and adheres to high environmental and social standards, reinforcing ARM strategic minerals Africa initiatives.

This substantial investment signals increased activity and potential for new legal work in Cameroon's mining sector, particularly in project finance, environmental compliance, and local content agreements. Lawyers should advise clients on regulatory changes or opportunities arising from this renewed focus on critical minerals development.
