The Sierra Leonean rutile mineralisation is hosted within alluvial and fluvial sedimentary facies of the Bullom Group Sediments. Mineralisation has been derived by the erosion of quartzo-feldspathic gneiss of the Precambrian Kasila group during the Tertiary and redeposited in preincised channel systems and alluvial fans flanking topographically elevated areas of the Kasila Group. The host sediments are typically poorly sorted sandy clay and sandy clays. Rubbly surficial laterite development is prevalent through much of the Bullom Group but does not hinder mining.If the leading edge of the Sembehun group of deposits is considered as a single mineralised entity then the width of the mineralisation is over 5000m. The deposits length varies from about 1000m to over 6000m. The deposits vary significantly in size from a few mt to over 150mt. In general the mineralisation is present from surface.
