Abstract: Rare metal placer deposits and gold placer are scattered in Nigeria's inland region. The spacial order of distribution is belt-like. Placers are of complex compositions. The usable minerals are mainly ilmenite, columbite-tantalite, zircon, thorite, monazite and cassiterite. Columbite-tantalite and cassiterite are the major mines for developing. Ilmenite, zircon, thorite, and monazite are always comprehensively assessed as associated minerals. Gold placer type we confirmed in this study is mostly alluvial. Rare metal placer deposits are alluvial and slope-washing. Considering the main character of inland placer in Nigeria, we propose placer drilling and sand drain as general assessing methods. Developing advice is given in this study.
