The Alto Ligonha pegmatite belt in northern Mozambique contains a number of historic tantalum and lithium mine workings including the Muiane mine. At some Alto Ligonha pegmatites, lithium (lepidolite) and caesium (mostly pollucite) were mined as by products (in addition to gemstones and industrial minerals). The most important Li-mineral deposits are those of Morrua, Muiane, Moneiea and Munhamola. The Chigaio prospect, located 9 kilometres south of Vundu, is a substantial lithium‐tantalum‐tin occurrence reportedly exhibiting many similarities to the Greenbushes lithium deposit in Western Australia.

 

• HAMC Lda is a private company and is the owner of the mining concessions for the three largest known pegmatites in Zambezia, northern Mozambique. In the case of Morrua they have used the historic core drilling that was done (some 16,500m) for the definition of a JORC compliant tantalum resource (some 5.3Mt at 500ppm) and have estimated, using a 0.6% cut-off, 22Mt of Li₂O (alternatively, applying a 0.9% cut-off 8.8Mt They estimate the Marropino tailings that were already mined and milled for tantalite, at 5.5Mt
