    Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides). The oxide ore bodies include stratiform, podiform, and breccia-related chromite
