Summary:
Ity is located in the Lower Proterozoic Birimian Formation of the Toulépleu-Ity klippe. The Toulépleu-Ity klippe is a small remnant of Birimian within the older Archean portion of the West African Craton. The Ity area is characterized by a series of granodioritic intrusions into a sedimentary sequence of volcano- sediments and carbonates with a general NE-SW strike. The volcanic rocks are generally tuffaceous with chemistry tha ranges from basic to acidic. All formations have been subjected to regional metamorphism.
The deposits of Ity are classified as skarn or typical shear-hosted greenstone deposits. The skarns developed at the contacts of a central northeast trending lensoidal shaped body of granodiorite intrusives with the carbonate units on both northwest and southeast contacts. The Ity, Ity Flat, Tontouo and Walter deposits are hosted along the southeastern contact, whilst Flotouo, Zia and ZiaNE are hosted along the northwestern contact. Bakatouo deposit is interpreted as being hosted by the northeast continuation of the carbonate units, whilst the Colline Sud skarn deposit represents the southwest continuation. The skarns are characterized by epidote, carbonate, diopside, chlorite, tremolite, magnetite and garnet with gold associated with pyrite and chalcopyrite. The Teckraie and Verse Ouest deposits are rock dumps of the now depleted Flotouo (skarn) open pit and sit on top of weathered granodiorite. Aires consists of the decommissioned heap leach pads f ........
Summary:
The selected mining approach is conventional open pit excavator-truck operation with the production unit operations (drilling, blasting, loading, hauling and dumping) carried out by mining contractors SFTP and SMS, with small earth works being done by Sopremi. The mining fleet consists of larger capacity 90 t dump trucks and 120 t class backhoe excavators. The 40 t articulated dump trucks are still utilized depending on pit and dump conditions, in particular, during the wet season. Ore and waste production rates are monitored, and material reconciliations are carried out continuously for the pit areas in production.
The production, drilling and blasting operations are carried out on 10 m benches. A half bench height (flitch) of 2.5 m is mined in ore to achieve a high degree of selectivity in loading and hauling operations. The highly weathered zone (clays and laterites) and transitional zone with a density below 2.0 t/m3 are amenable to free digging. Emulsion is used in both wet and dry blasting for efficiency.
