Development in modern-high technology application is growing rapidly, resulting constant supply of critical metal and rare earth elements (REE). Meanwhile, source of these elements are limited and consequently new source of these elements need to be discovered. Scandium (Sc) as one of the critical metals is an important metal for electrolyte of solid oxide fuel cells and the demand is likely to increase in the near future. In addition, REE is an important element in the use of permanent magnets and rechargeable batteries. Information on the occurrence of scandium and rare earth elements are still very limited and therefore exploration activity in Indonesia is still scarce. Based on the most update investigation, scandium can be extracted from weathering crust of highly weathered nickel-contained ultramafic rock. New report suggests that Sc3+ enriched in mafic minerals such as pyroxene, amphibole and magnetite and poor in olivine. Scandium will be concentrated in limonite and saprolite layer, but the volume of enrichment is still unknown. Meanwhile, rare earth element found in granitic rocks particularly in zircon, monazite and xenotime and it has been reported that rare earth ore were extracted from heavily weathered granitic rocks from some areas. Sulawesi Island is one of the islands where lateritic deposits from heavily weathered ultramafic and granitic rocks are widely distributed. The lateritic soil of the ultramafic rocks can be potential source of scandium and the granitic rocks could be the potential source of rare earth element. This manuscript reports an update on the critical metal, particularly scandium and rare earth element occurrence in Sulawesi Island based on petrology and geochemistry data..
