Mafic and ultramafic intrusions observed in the Archean formations of the Sipilou region exhibit occurrences of polymetallic sulphide. Mapping, petrographic and geochemical studies have defined magnetic facies associated with the various geological units. The results of this work reveal that cupronickel sulphides, olivines and pyroxenes as well as spinels are related to ultrabasic formations where strong magnetic facies prevail. Iron sulphides and magnetite are linked to quartzo-feldspathic and jotunite-enderbite formations, which are characterised by moderate magnetic facies. The latter are thought to be derived from anatexite remobilisation within Archean granulites, which have weak magnetic facies.
