  SAKARO The Sakaro deposit is loed some 4 km SW of Lega Dembi. Gold mineralisation is hosted in an enechelon quartzvein system developed in graphitic metapelites parallel to the contact between massive amphibolites and metasediments, the latter being correlated stratigraphically with the metasediments of the Lega Dembi area. The ore is hosted by goldrich and sulphidepoor quartz veins
