The four projects, each of which has a mining license, are located along the 210 kilometre long Twangiza-Namoya gold belt in the South Kivu and Maniema provinces of the Democratic Republic of the Congo. Led by a management team with extensive gold and African experience, the initial focus of the Company is on the mining of oxide material, which has a low capital intensity to develop but also attracts a lower technical and financial risk to the Company. All business activities are followed in a socially and environmentally responsible manner.
