Sulphide mineralizations, confined to narrow chromitite zones at the contact with dikes of pegmatitic olivine norites. Started production in 1889 and has produced 450,000 t of refractory-grade chromite.

The Potosí chromitites are located 800 m deeper than the layered gabbros forming the MTZ at the Moa-Baracoa Ophiolitic Massif. They form lenses of variable sizes and irregular shapes (tabular to lenticular) hosted in dunite within harzburgite. The bodies are oriented N 40° E to N 74° E with dips between 32° and 45° to the NW, usually filling the foliation of the host peridotites. Several generations of gabbroic intrusions crosscut the chromitite bodies, usually following pull-apart fractures with brecciated zones at their margins. Dikes have highly variable thicknesses, from a few centimeters to 2 m across and locally show a distinct grain-size zoning with pegmatitic textures in the dike cores that reach grain sizes larger than 15 cm and finer grain sizes closer to the contacts with chromitite. Disrupted fragments of chromitite occur as inclusions within the gabbroic intrusions. The contacts between the chromitites and the gabbroic intrusions may be either neat or gradational, the latter characterized by a brecciated zone where chromite is included within the gabbroic dikes. Chromitite in Potosí can be classified as: i) ordinary podiform chromitite, preexistent to gabbroic intrusions, or ii) metasomatized chromitite, associated with or intruded by gabbroic dikes and denoted as “brecciated chromite ore” and “sulfide-rich chromite ore”. Ordinary chromitites represent more than 90 vol.% of the ore body and show mineralogical, textural and chemical features similar to other Al-rich chromitite bodies in the MBOB and ophiolitic complexes worldwide. Metasomatized chromitite is composed mostly of recrystallized Ti- and Fe3+ - rich chromite, Ti-rich amphibole, orthopyroxene, clinopyroxene, plagioclase, and Fe-Cu-Ni sulfides, the latter formed by fractionation of immiscible sulfide liquid segregated from the mafic intrusions.
