The Man Shield straddling the West African countries of Senegal, Sierra Leone, Mali, Ivory Coast Burkina Faso, Ghana and Niger, consists of the Archean Kenema-Man Domain and the Paleoproterozoic Baoul-Mossi Domain. It is characterized by World-class deposits of gold, iron and manganese which are located in this 1.1 million square km area. Few base-metal sulphide occurrences of economic interest have been described, although geological formations of similar age (Archean and Paleoproterozoic) in other parts of the world host large zinc, copper and nickel deposits. The purpose of this paper is to provide a metallogenetic inventory of the Man Shield, to assist in the evaluation of known sulphide occurrences as well as supporting the exploration of new deposits. The volume summarises the Base metal potential of the Lower and Middle Precambrian of West Africa by providing lithologic data, drill cores, thin section photographs of prevalent rocks and provides a 1:2000000 scale geological sheet map of the Man Shield Area (included).
