摘要
The Suwar Cu-Ni sulphide prospect is very highly regarded for its potential to host a major nickel-copper sulphide deposit in Republic of Yemen, a mineral resource lacking country. The ore-hosting intrusion is a lopolith about 6km long and lkm wide and more than 300m deep. There are two types of Cu-Ni mineralizations in the prospect: primary massive chalcopyrite+ pyrrhotite+ pentlandite controlled by gravitational and structural traps while the secondary Cu-Ni mineralization is coarse grained and occur as veins, veinlets, fracture fill, blebs or associated with coarse, re-crystallized carbonate in shear zones and faults. The deposit type of the prospect is believed to be the one associated with the ultramafic component of a large, broadly differentiated noritic, gabbroid intrusive. It is suggested that the prospect and adjacent area possibly contain a similar world class Ni-Cu deposits as that in Jinchuan, China.
