Localities for Tantalite are pretty much the same as Columbite, and it often is not identified individually but more generally as Columbite-Tantalite. Specific localities that have produced exceptional Tantalite include the São Pedro Mine, Malacacheta, Minas Gerais, Brazil, where it was found in blocky crystals; the Shigar Valley, Skardu, Gilgit-Baltistan, Pakistan, as
pseudomorphs of Microlite; and Ankole, Mbarara District, Uganda; where the manganese-rich
end member has been found in dark red, translucent crystals.
