The Brazilian mining giant Vale on April 25, 2022 concluded the sale of its Mozambican coal production assets (the Moatize coal mine and the Nacala Logistical Corridor) to Vulcan Minerals is a private company. Vale had an indirect 95% stake and the remaining stake is owned by Empresa Moçambicana de Exploração Mineira, S.A.
The Matinde formation is the uppermost Karoo formation in the Tete/Moatize area and is comprised of a uniform series of coarse, highly compact cross bedded sandstones with locally developed conglomerates. Thin high ash coal and carbonaceous shales occur intermittently throughout the Matinde formation, but are not of economical value.In the Moatize-Minjova basin, economically significant coal seams are present at intervals over a total stratigraphic thickness of 317 m within the Serie Produtiva only. It consists of a sequence of shales, mudstones and siltstones, intercalated with coal seams and carbonaceous shales. The sediments were deposited in a deltaic environment under stable conditions and slow subsidence. Coal is contained in six multi-seam coal bearing zones known stratigraphically from the youngest to the oldest as:- Andre (± 1.5 m).- Grand Falesia (± 11 m).- Intermedia (± 9 m).- Bananeiras (± 40 m).- Chipanga (± 35 m).- Souza Pinto (± 13 m).Seams consist of bright coal, mainly vitrinite, alternating with dull detrital coal, carbonaceous shale and shale. The shale to coal ratio in the Chipanga seam is in the order of 60/40.The Chipanga Seam is economically the most important of the coal seams, as it is thicker and laterally more extensive and therefore has the largest reserves.The Moatize-Minjova Coal basin is a NW-SE trending graben, 20 km long and 7 km wide, associated with the Zambezi Valley distension zone. The graben is bounded by normal faults with throws of between 500 m and 800 m, which are marked by thick fault breccias.
