The map supersedes an earlier version of the International Mineral Deposit Map of Africa (Sheet 1), produced in 1991. It was predominantly compiled by a team of 5 members, led by Dr. Erik Hammerbeck, Milica Veselinovic-Williams and Susan Frost-Killian. Several coauthors and co-operators, including various research institutions and most of the African and Middle Eastern Geological Surveys, as well as the Bureau de Recherches Géologiques et Minières (BRGM, French Geological Survey), assisted with the compilation and verification of the mineral deposit and background geological data.
