Cameroon Projects

Cameroon is host to some of the world’s major bauxite reserves, with deposits found in several locations throughout the country. The Company proposes to acquire two license areas known as Bangem and Fontem in the Republic of Cameroon. The licenses in Cameroon are currently under application. No drilling or modern exploration has been undertaken within the area.

Congo Projects

The Congo Projects comprise 6 contiguous concessions across two regions, totalling ~3,000km[2] . The northern concessions are referred to as the Kouyi Project, and are well known within Congo as a highly prospective bauxite region. The southern Kibangou Project is also understood to be similarly prospective for bauxite. All licenses are currently under application.

The projects have received no modern exploration work, with the most recent work completed in the 1960s.
