Localities

At the type locality, the Foote Lithium Co. Mine, Kings Mountain Mining District, Cleveland county, North Carolina, USA, whiteite-(MnMnMn) was found in small vugs of partially oxidised pegmatite minerals on the East dump of the mine, in association with eosphorite, hureaulite, fairfieldite, mangangordonite, whiteite-(CaMnMn) and jasonsmithite. It occurs as sugary aggregates of blade-like crystals up to 0.1 mm long and as epitaxial overgrowths on whiteite-(CaMnMn) (MM 85.6.862-867).
