One of the world's largest undeveloped cobalt-nickel deposits, located in Cameroon's East Province
The Nkamouna project is located in the Haut Nyong Division, East Province of Cameroon. The project site is approximately 400 kilometers by road to the port of Kribi and about 300 km from the capital city of Yaoundé.
The closest town is Lomié, at approximately 26 kilometers to the west-southwest. The project benefits from existing road infrastructure and is positioned to gain from Cameroon's ongoing infrastructure upgrades, including the planned Mbalam iron ore railroad passing within 60 km (estimated completion 2030).
The prior mining permit covers a vast area of 1,650 km², of which only approximately 10% has been explored to date, highlighting significant upside potential for resource expansion.
The Nkamouna and Mada mineral resources have been audited by SRK in 2011. The deposits are unusual in their high Co:Ni ratio (~1:3), high cobalt grade (0.24%), and very low content of magnesium oxide. All cobalt and approximately half the nickel is contained in the mineral asbolane, a relatively hard mineral that is uniquely coarse in these deposits.

Based on SRK 2011 NI 43-101 Feasibility Study. Reserve stated above 0.12% cobalt cut-off for ferralite and 0.23% cobalt cut-off for breccias.
The December 2023 Mining Code mandates a 10% free-carried interest for SONAMINES. ARM is fully committed to compliance with Cameroon's updated regulatory framework.
A proposed Mining Permit to be held by a Cameroonian subsidiary of ARM with local private sector partner Codias, including the mandated 10% SONAMINES interest.
DPA Title III application submitted. Ongoing advocacy from U.S. Department of Commerce and State Department, including SONAMINES delegation meetings.
