  ABSTRACT: This article examines the lithostratigraphy and typology of manganese mineralization on the Lebaye plateau based on trench observations and approximately one hundred rock samples analyzed by portable X-ray fluorescence. It identifies lamellar manganese ore as the main exploitable facies within a supergene alteration profile derived from manganese-bearing ampelites of the Francevillian succession. The manuscript also classifies the ore as medium-grade and raises hydrogeological considerations relevant to the future development of the quarry.
