An intrusion including nepheline syenite is known to occur in the Makutu Hills, 29 km north of Mivula Hill (No. 180-00-003) (Newton, 1959), but no account of this occurrence has been located except for a detailed petrographic description of a single specimen by Adams and Osborne (1932). The rock consists of microcline perthite, nepheline, partly or completely altered to cancrinite and replaced by sodalite, aegirine, biotite, magnetite, ilmenite, pyrite, chalcopyrite, zircon and calcite.
