Sierra Leone is 75% underlain by rocks of Precambrian age comprising a granite greenstone terrain on the edge of the West African Craton. Four classic greenstone belts are preserved namely the Kambui Hills, the Sula Mountains/Kangari Hills belt, the Nimini Hills and the Gori Hills. Taia has gold exploration properties in two of these belts in the Sula Mountains around Lake Sonfon area (1), and in the Gori Hills (2).
These schist belts host important mineralisation including gold, chromite, tin, copper, antimony, arsenic and iron ore. Whilst advanced gold project development is scarce in Sierra Leone (two projects have reached feasibility study level), there are already two world-class iron ore deposits under development in the country.
Gold was first discovered in the Sula Mountains in 1926 and has been mined artisinally and in a semi-industrial scale ever since from all the four classic greenstone terrains. Primary deposits are generally presented as high-grade lodes, typical of archaean greenstone belts world wide. The mineralisation is commonly mesothermal shear hosted in mafic and ultra-mafic rocks, but can be intrusion related associated with younger granities, and is also commonly BIF associated.
Sierra Leone is an exciting early stage gold exploration province with an abundance of the right rocks and a very high degree of prospectivity. Taia has licences in two of the principal regions and is extremely well placed to significantly further develop these properties.
